The embodiments of the present application will be described below with reference to the drawings.
The embodiment of the application provides a laminating equipment. The laminating equipment is used for laminating the curved cover plate and the flexible screen.
The curved surface cover plate is of a structure with a curved surface attaching area. For example, the curved cover plate may be a protective cover plate with an arc-shaped edge applied to various electronic devices, and the attaching surface on the inner side of the protective cover plate includes an attaching area having a curved surface. The protective cover plate can be a front cover plate or a rear cover plate of the electronic equipment. In one embodiment, the curved attachment area may have a bend angle greater than or equal to 60 ° where the curved cover is a large curvature curved cover. In another embodiment, the bending angle of the curved attachment area may be greater than 0 ° and less than 60 °, and the curved cover plate is a curved cover plate with a small curvature. In another embodiment, the curved surface of the attachment area may have a curvature of 0 °, in which case the curved surface cover plate is substantially a flat surface cover plate.
The flexible screen can be a flexible display screen, a flexible touch screen with integrated display function, a flexible heat dissipation film, a flexible decoration film or other flexible screen structures. In the embodiment of the present application, a curved surface cover plate is taken as a front cover plate of an electronic device, and a flexible touch screen with an integrated display function is taken as an example for explanation, and after the curved surface cover plate is attached to the flexible touch screen, a curved surface screen of the electronic device is formed.
In the embodiment of the application, the curved surface cover plate and the flexible screen are stacked and attached together along the first direction by the attaching equipment. The laminating equipment comprises an installation assembly, a clamping assembly and a laminating assembly. The mounting assembly is used for mounting the curved cover plate. The clamping assembly is used for clamping two ends of a bearing film bearing the flexible screen, and the bearing film is located between the mounting assembly and the attaching assembly. The attaching assembly and the mounting assembly can move relatively in a first direction. The laminating subassembly includes first slider, second slider and laminating pad. The first slider and the second slider are arranged in the second direction and can approach and move away from each other. The second direction is perpendicular to the first direction. The attaching pad is made of elastic material. The pad can deform when stressed. The fit pad is positioned on one side of the first sliding block and the second sliding block facing the installation component. The fit pad extends from one side of the first slider, which is far away from the second slider, to one side of the second slider, which is far away from the first slider. The laminating pad is used for supporting the flexible screen and is laminated and laminated together with the curved surface cover plate along the first direction.
The process of laminating curved surface apron and flexible screen of laminating equipment includes two steps: the first step is that the first sliding block and the second sliding block are close to each other to a close state, the attaching component and the mounting component move relatively in a first direction, so that the first sliding block and the second sliding block support the middle area of the flexible screen through the attaching pad (or support the flexible screen through the attaching pad by the pressing block, which is detailed in a third embodiment) and the middle area of the curved cover plate to contact and attach; and the second step is that the first sliding block and the second sliding block are far away from each other along the second direction to an open state, so that the first sliding block and the second sliding block further support the edge area of the flexible screen and the edge area of the curved cover plate to be attached through the attaching pad. In short, the curved cover plate and the flexible screen are firstly attached to the middle area and then attached to the edge area in the attaching device, so that complete attachment is completed. By the mode of middle zone toward the laminating of edge region, can reduce bad risks such as bubble, crackle, fold to appear for the laminating quality of curved surface apron and flexible screen is better, and the product yield of the screen that forms after curved surface apron and the laminating of flexible screen is higher.

Also, the same or similar explanations will be used for similar descriptions of the positional relationships among the plurality of components in the following.
Optionally, the clamping assembly is further configured to maintain the carrier film in a tensioned state during the attachment of the curved cover plate to the flexible screen. The laminating process is a process of laminating the curved cover plate and the flexible screen. At the moment, in the laminating process of the curved-surface cover plate and the flexible screen, the bearing film is kept in a tensioning state, so that the flexible screen is always in a flat state, the risk of generating air bubbles, cracks, folds and other defects is lower when the curved-surface cover plate is laminated with the flexible screen, and the laminating quality of the curved-surface cover plate and the flexible screen is further improved.
Wherein, in this application, the laminating process begins the process of laminating to accomplishing the laminating for curved surface apron and flexible screen. And the part to be attached of the curved cover plate is at least partially contacted with the part to be attached of the flexible screen. And the part to be jointed of the curved cover plate is completely jointed with the part to be jointed of the flexible screen after the jointing is finished. The part to be attached of the curved cover plate can be a partial area of the curved cover plate, for example, an attachment surface or a partial area of the attachment surface of the curved cover plate facing the flexible screen in the attaching process. The portion of the flexible screen to be attached may be a partial region of the flexible screen, for example, a surface or a partial region of the surface of the flexible screen facing the curved cover plate during the attaching process.
Optionally, the support structure of the flexible screen has multiple embodiments by the attaching assembly:
in one embodiment, the first slider and the second slider jointly support the fit pad, and the relative movement of the first slider and the second slider is active movement.

Referring to fig. 3 and 4 together, fig. 3 is a schematic structural view of a portion of the attaching apparatus 100 shown in fig. 1, and fig. 4 is a schematic structural view of the structure shown in fig. 3 in another use state. Fig. 3 and 4 mainly include structures of the cavity assembly 2 and the fixing frame 1 of the attaching device 100.
Optionally, the second cavity 22 is mounted to the fixation frame 1. The first cavity 21 is slidably mounted to the fixing frame 1. The first chamber 21 is movable in a first direction Z relative to the second chamber 22 to be in an open state with the second chamber 22 (as shown in fig. 3) or in a closed state with the second chamber 22 (as shown in fig. 4).
For example, the second cavity 22 may be fixed to the support plate 13. The chamber body assembly 2 further comprises a movable mounting plate 23. The movable mounting plate 23 is connected with the fixed frame 1 in a sliding way. The movable mounting plate 23 is located above the first cavity 21.

In one embodiment, the retractable hanger 241 comprises a retractable sleeve and a spring disposed outside the retractable sleeve.
When the movable mounting plate 23 moves along the first direction Z and the first cavity 21 is in a suspended state, the first cavity 21 moves along with the movable mounting plate 23. When the movable mounting plate 23 moves along the first direction Z and the first chamber 21 is in a non-suspended state (e.g., supported by the second chamber 22), the distance between the two ends of the retractable suspension 241 of the first suspension assembly 24 changes, and the first chamber 21 does not move with the movable mounting plate 23.
The chamber body assembly 2 further comprises a first chamber body driving assembly 25.

The first chamber driving assembly 25 is further configured to drive the first chamber 21 away from the second chamber 22 along the first direction Z to an open state. For example, the first cavity drive assembly 25 includes one or more first cavity drives 251. In this embodiment, the first cavity driving assembly 25 includes two first cavity driving members 251, and the two first cavity driving members 251 are respectively connected to two ends of the movable mounting plate 23. The first cavity driving member 251 is used for driving the movable mounting plate 23 to move along the first direction Z.
The process of transforming the first cavity 21 and the second cavity 22 from the open state to the closed state includes: the first cavity driving assembly 25 drives the movable mounting plate 23 to approach the second cavity 22 along the first direction Z, and the first cavity 21 approaches the second cavity 22 along with the movable mounting plate 23 until the first cavity 21 abuts against the second cavity 22 and is combined with the second cavity 22. After the first cavity 21 abuts against the second cavity 22, the first cavity driving assembly 25 can drive the movable mounting plate 23 to further approach the second cavity 22, so that the abutting connection between the first cavity 21 and the second cavity 22 is more reliable, and the sealing performance of a working cavity formed by the first cavity 21 and the second cavity 22 is better.
The process of transforming the first cavity 21 and the second cavity 22 from the closed state to the open state includes: the first cavity driving assembly 25 drives the movable mounting plate 23 to be away from the second cavity 22 along the first direction Z, and the first cavity 21 is away from the second cavity 22 along with the movable mounting plate 23, so that the closed state is released. If the movable mounting plate 23 moves a greater distance relative to the first cavity 21 during the combining process of the first cavity 21 and the second cavity 22, the movable mounting plate 23 first moves away from the second cavity 22 by a distance during the separating process of the first cavity 21 and the second cavity 22, and then drives the first cavity 21 to move away from the second cavity 22.
The first cavity driving member 251 is a servo motor. The servo motor adopts a closed-loop feedback system and has accurate position precision, so that the position of the movable mounting plate 23 can be accurately controlled, the position precision of the first cavity 21 is high, and the reliability of the laminating process of the laminating equipment 100 is ensured. In other embodiments, the first cavity driving member 251 may also be a common motor or an air cylinder.

The conduit communicates with the working chamber, for example, one end of the conduit may be mounted to the first cavity 21 or the second cavity 22. When the working chamber is vacuumized, the bonding quality of the curved cover plate 200 and the flexible screen 300 can be improved, and the risk of generating bubbles is reduced. Optionally, the laminating apparatus 100 may further include a vacuum breaking assembly.
Referring to fig. 5, fig. 5 is a schematic structural view of the first cavity 21 and the second cavity 22 shown in fig. 3 at another angle.
Optionally, one or both of the first cavity 21 and the second cavity 22 are provided with a window 26. During the attaching process, the orthographic projection of the curved cover plate 200 and the flexible screen 300 along the third direction to the first cavity 21 or the second cavity 22 is located in the window 26. The third direction is perpendicular to the first direction Z and the second direction X. The attaching process is a process of attaching the curved cover plate 200 to the flexible screen 300. "orthographic projection" means that parallel projection lines are perpendicular to the plane of projection.
In this embodiment, whether bubbles caused by gaps exist in the attaching process of the curved surface cover plate 200 and the flexible screen 300 or flatness and the like in the attaching process of the curved surface cover plate 200 and the flexible screen 300 can be observed through the window 26, so that the reason of poor attaching is known, process parameters in the attaching equipment 100 are adjusted in time, the attaching precision of the attaching equipment 100 is improved, and material waste can be reduced.
It is understood that in other embodiments, the attaching process may also be a partial process from the beginning of the attaching process of the curved cover plate 200 to the flexible screen 300 to the completion of the attaching process, for example, an edge region of the curved cover plate 200, which is prone to generate bubbles, is attached to an edge region of the flexible screen 300.
As shown in fig. 5, in the present embodiment, the first cavity 21 is provided with a window 26. The curved cover plate 200 and the flexible screen 300 are located in the first cavity 21 during the attaching process.

In other embodiments, second lumen 22 is provided with a window. The curved cover plate 200 and the flexible screen 300 are positioned within the second cavity 22 during the attachment process. During the attachment process, the orthographic projection of the curved cover plate 200 and the flexible screen 300 in the third direction to the second cavity 22 is located within the viewing window.
In other embodiments, the first cavity 21 and the second cavity 22 are provided with a window 26. The curved cover plate 200 and the flexible screen 300 are located in a working chamber formed by the first cavity 21 and the second cavity 22 during the attaching process. During the attaching process, the orthographic projections of the curved cover plate 200 and the flexible screen 300 along the third direction with the first cavity 21 and the second cavity 22 are located in the window 26.
It is understood that the present application does not strictly limit the number, arrangement position, shape, etc. of the viewing windows 26, but sets the viewing windows according to the region where the curved cover plate 200 and the flexible screen 300 are located during the attaching process.
Referring to fig. 5, optionally, the attaching apparatus 100 further includes a monitoring camera assembly 6. The monitoring camera assembly 6 is located outside the first cavity 21 and the second cavity 22, and is configured to obtain image information in the first cavity 21 and the second cavity 22 through the window 26. At this time, the monitoring camera assembly 6 can acquire image information in the working chamber through the window 26, so that a user can record the attaching operation process of the attaching device 100 conveniently. In addition, the monitoring camera assembly 6 is positioned outside the working chamber, and the influence on the attaching process can be reduced. The monitoring camera shooting assembly 6 is located outside the working chamber instead of inside the working chamber, so that the monitoring camera shooting assembly 6 cannot vacuumize the working chamber in the laminating process due to the laminating equipment 100, explosion occurs due to negative pressure in a vacuum environment, the monitoring camera shooting assembly 6 is protected, and the service life is prolonged.
The image information at least includes image information of the edge region of the curved cover plate 200 and the edge region of the flexible screen 300 in the attaching process. The image information may further include image information of the middle region of the curved cover 200 and the middle region of the flexible screen 300 during the attaching process.
Wherein the monitoring camera assembly 6 comprises one or more cameras 61. When the number of the cameras 61 is plural, the plurality of cameras 61 may be used to acquire different image information in the first cavity 21 and the second cavity 22. The present embodiment is described by taking an example in which the monitoring camera assembly 6 includes two cameras 61. The two cameras 61 may be used to respectively obtain image information of the edge area of the curved cover plate 200 and the edge area of the flexible screen 300 during the attaching process, and image information of the middle area of the curved cover plate 200 and the middle area of the flexible screen 300 during the attaching process.
The monitoring camera assembly 6 further includes a guide rail 62 and a camera support 63. One end of the camera bracket 63 is connected with the camera 61. The other end of the camera bracket 63 is slidably attached to the guide rail 62. The guide rail 62 may include a first sub-guide 621 and a second sub-guide 622.

The second sub-rail 622 moves in the second direction X. The end of the camera support 63 remote from the camera 61 is slidably mounted to the second sub-rail 622. At this time, the camera 61 has the degree of freedom in the first direction Z and the degree of freedom in the second direction X, so that the image information in the first cavity 21 and the second cavity 22 can be acquired more flexibly.
It is understood that there are various ways to realize the number, structure, shape, etc. of the guide rails 62 of the monitoring camera assembly 6, and the design is performed according to the required moving path of the camera 61, which is not strictly limited in this application.
In other embodiments, the monitoring camera assembly 6 may also be used in a vacuum environment, and in this case, the monitoring camera assembly 6 may be located inside the first cavity 21 and the second cavity 22. For example, the camera 61 of the monitoring camera assembly 6 may be an open type camera, and thus normally operates in a vacuum environment. Alternatively, the guide rail structure and the camera support structure may be correspondingly disposed inside the first cavity 21 and the second cavity 22.
Referring to fig. 6, fig. 6 is a schematic partial structure diagram of the bonding apparatus 100 shown in fig. 1. Fig. 6 mainly includes the structures of the mounting assembly 3, a part of the cavity assembly 2, and a part of the fixing frame 1 of the attaching apparatus 100.
Optionally, the mounting assembly 3 includes a mounting base 31. The mounting base 31 has a mounting station 311, and the mounting station 311 is used for mounting the curved cover plate 200. The mounting base 31 is movable up and down in the first direction Z. For example, when the attaching apparatus 100 is not attached, the mounting base 31 is located in the first cavity 21. When the attaching device 100 is attached, the mounting base 31 may be located in the first cavity 21 or may be moved into the second cavity 22.
Alternatively, the mounting base 31 may be provided with one or more vacuuming holes (not shown). The vacuuming hole is communicated to the mounting station 311 to absorb the curved cover plate 200 on the mounting station 311 by negative pressure.
In the embodiment of the present application, the mounting base 31 has a plurality of driving manners, for example:
in one embodiment, as shown in fig. 6, the mounting assembly 3 further includes a mounting base drive 32. The mounting base driver 32 is used to drive the mounting base 31 to move in the first direction Z. The mounting base drive 32 may be mounted on the movable mounting plate 23. At this time, the mounting base 31 may move with the movable mounting plate 23, or may move relative to the movable mounting plate 23 by the driving of the mounting base driving member 32. Therefore, the installation base driving member 32 is provided, so that the installation base 31 has higher mobility, and the process in the attaching process of the attaching device 100 is more diversified.
Wherein the mounting assembly 3 further comprises a mounting platform 33. The mounting platform 33 includes a fixing portion 331 located inside the first cavity 21, a driving portion 332 located outside the first cavity 21, and a connecting portion 333 connected between the fixing portion 331 and the driving portion 332. The mounting base 31 is mounted to the fixed portion 331 of the mounting platform 33. The mounting base drive 32 is connected to the drive portion 332 of the mounting platform 33. The first cavity 21 is provided with a first through hole 211. The first through hole 211 communicates the inner space and the outer space of the first chamber 21. The connection part 333 of the mounting platform 33 passes through the first through hole 211. The mounting assembly 3 further comprises a first vacuum bellows 34. The first vacuum bellows 34 is sleeved outside the connecting portion 333 of the mounting platform 33 for sealing the first through hole 211, so that the working chamber formed after the first cavity 21 and the second cavity 22 are sealed can maintain a vacuum environment.
Wherein the mounting assembly 3 further comprises a second suspension assembly 35. The second suspension assembly 35 comprises a plurality of telescopic hangers 351. A plurality of retractable hangers 351 are spaced apart from each other. Both ends of each telescopic hanger 351 are connected to the movable mounting plate 23 and the driving portion 332 of the mounting platform 33, respectively. The spacing between the ends of the retractable hanger 351 is adjustable. The mounting base 31 is connected with the movable mounting plate 23 through the mounting platform 33 and the second suspension assembly 35, and the mounting base 31 can move along with the movable mounting plate 23 and can also move relative to the movable mounting plate 23. In one embodiment, the retractable suspension 351 includes a retractable sleeve and a spring disposed outside the retractable sleeve.
Wherein the mounting assembly 3 further comprises a third pressure sensor 36. The third pressure sensor 36 is used for detecting the attaching pressure of the curved cover plate 200 and the flexible screen 300 in the attaching process. The third pressure sensor 36 may be disposed between the mounting platform 33 and the mounting base driving member 32 to accurately and timely detect the bonding pressure applied to the curved cover plate 200. At this time, since the third pressure sensor 36 can feed back the bonding pressure between the curved surface cover plate 200 and the flexible screen 300 in real time, the process parameters of the bonding apparatus 100 are adjusted in time according to the detection data, and the risk of the occurrence of the problem of poor bonding (for example, the curved surface cover plate 200 or the flexible screen 300 is damaged due to too large bonding pressure, the bonding is not in place due to insufficient bonding pressure, and the like) is reduced, so that the bonding quality between the curved surface cover plate 200 and the flexible screen 300 is better. In other embodiments, the third pressure sensor 36 may be disposed at other positions capable of detecting the bonding pressure of the curved cover 200.
In another embodiment, please refer to fig. 7, fig. 7 is a schematic structural diagram of the structure shown in fig. 6 in another embodiment. Most technical contents of the structure shown in fig. 7 which are the same as those of the structure shown in fig. 6 are not described again.
In the present embodiment, the mounting unit 3 is not provided with a mounting base driver. The mounting base 31 is movably connected with the movable mounting plate 23 through a mounting platform 33 and a second suspension assembly 35. The mounting base 31 can move with the movable mounting plate 23 in a suspended state. When the mounting base 31 is subjected to other external forces, the mounting base 31 can move relative to the movable mounting plate 23. For example, when the first chamber 21 and the mounting base 31 are both in a suspended state, the first chamber 21 and the mounting base 31 move along with the movable mounting plate 23 and are driven by the first chamber driving assembly 25 to move. When the first chamber 21 is in a non-suspended state (e.g., supported by the second chamber 22) and the mounting base 31 is in a suspended state, the first chamber 21 no longer moves along with the movable mounting plate 23, but the mounting base 31 moves along with the movable mounting plate 23, and the first chamber driving assembly 25 drives the mounting base 31 to move.
In this embodiment, because the mounting base 31 is movably connected to the movable mounting plate 23, when the curved cover plate 200 mounted on the mounting base 31 is under a large pressure (for example, the pressure during the attaching process), the mounting base 31 can move a little relative to the movable mounting plate 23, so as to play a role in buffering, reduce the risk of damage to the curved cover plate 200 caused by an excessive pressure, and make the attaching process more reliable.
In the embodiment of the present application, there are various methods for fixing the curved cover plate 200 to the mounting base 31, for example:
in one embodiment, please refer to fig. 8, wherein fig. 8 is a partial structural diagram of the structure shown in fig. 6. Fig. 8 mainly includes a structure of a part of the mount assembly 3.
The mounting assembly 3 further comprises a first clamping block 37 and a second clamping block 38. The first and second clamping blocks 37, 38 are arranged in the third direction Y and are relatively movable in the third direction Y. The third direction Y is perpendicular to the first direction Z and the second direction X. The first and second clamping blocks 37, 38 are located on either side of the mounting station 311. When the first clamping block 37 and the second clamping block 38 approach each other to the first position, the distance between the first clamping block 37 and the second clamping block 38 is equal to the length of the curved cover plate 200 in the third direction Y, and the first clamping block 37 and the second clamping block 38 clamp the curved cover plate 200 in the third direction Y, thereby fixing the curved cover plate 200. When the first clamping block 37 and the second clamping block 38 are away from each other to the second position, the distance between the first clamping block 37 and the second clamping block 38 is greater than the length of the curved cover plate 200 in the third direction Y, and the curved cover plate 200 can be loaded into the mounting station 311 or unloaded from the mounting station 311.
There are various relative movement manners between the first clamping block 37 and the second clamping block 38, for example, both can move in the third direction Y, or one of them is fixed and the other can move in the third direction Y. In the present embodiment, the first clamp block 37 is fixedly attached to the mounting platform 33, and the second clamp block 38 is movably attached to the mounting platform 33. The mounting assembly 3 further comprises a clamping block drive 39. The clamping block drive 39 may be mounted to the mounting platform 33. The clamping block driving member 39 is used for driving the second clamping block 38 to move in the third direction Y to approach or move away from the first clamping block 37.
Wherein the first clamping block 37 comprises a first wear layer 371 directed towards the second clamping block 38. The first wear-resistant layer 371 is a surface structure of the first clamping block 37 facing the second clamping block 38. For example, the first wear-resistant layer 371 may be assembled or integrally formed with other materials to form the first clamping block 37. Alternatively, the first clamping block 37 may be made of a wear-resistant material as a whole, and the surface structure of the first clamping block 37 facing the second clamping block 38 forms the first wear-resistant layer 371. The material of the first abrasion resistant layer 371 may be an abrasion resistant plastic material or a metal material. Examples of the wear-resistant plastic material include Polytetrafluoroethylene (PTFE), acrylic, polypropylene, and polyvinyl chloride. A wear resistant metallic material such as stainless steel. The formation manner and material of the first abrasion resistant layer 371 are not strictly limited in this application. Optionally, the second clamping block 38 comprises a second wear layer 381 facing the first clamping block 37. The design of the second wear-resistant layer 381 can be referred to the first wear-resistant layer 371.
In the present embodiment, since the first clamping block 37 includes the first wear-resistant layer 371 and the second clamping block 38 includes the second wear-resistant layer 381, the first clamping block 37 and the second clamping block 38 can be applied to a batch processing environment and have a long service life. In addition, when the first wear-resistant layer 371 and the second wear-resistant layer 381 are made of materials with a buffering effect, the risk that the curved-surface cover plate 200 is damaged due to too large impact force is reduced in the process that the curved-surface cover plate 200 is clamped by the first clamping block 37 and the second clamping block 38, and the processing yield of the attaching device 100 is higher.
It is understood that in other embodiments, the side of the first clamping block 37 facing the second clamping block 38 may be surface-treated, and the side of the second clamping block 38 facing the first clamping block 37 may be surface-treated, so as to increase the surface friction force of the first clamping block 37 and the second clamping block 38 and improve the wear resistance.
Wherein the mounting assembly 3 further comprises an adjustment structure 310. The mounting base 31 is slidably mounted to the mounting platform 33. The adjustment structure 310 is mounted to the mounting platform 33 for adjusting the position of the mounting base 31 in the second direction X. The adjustment structure 310 may include one or more micrometers.
At this time, when the curved cover plate 200 is mounted on the mounting base 31, the position in the first direction Z can be adjusted by the mounting base driving member 32 (or the first cavity driving assembly 25), the position in the second direction X can be adjusted by the adjusting structure 310, and the position in the third direction Y can be adjusted by the first clamping block 37 and the second clamping block 38, so that the curved cover plate 200 has three degrees of freedom in three directions, and the position can be flexibly adjusted in the process of attaching to the flexible screen 300, thereby obtaining a better attaching effect.
In another embodiment, the mounting station 311 of the mounting base 31 may be a recess having a shape and size adapted to the curved cover 200. The groove can be made of metal (such as stainless steel, plastic steel and the like), plastic (such as acrylic and the like) and other materials with small deformation and high hardness.
Referring to fig. 9, fig. 9 is a schematic partial structural view of the bonding apparatus 100 shown in fig. 1. Fig. 9 mainly includes the structure of the clamping assembly 4, the second cavity 22 and the fixing frame 1 of the attaching device 100.

First portion 431 and second portion 432 of clamping platform 43 are spaced apart from each other and are positioned on opposite sides of conformable assembly 5 (see FIG. 2). Wherein, the second cavity 22 is provided with a second through hole 221 and a third through hole 222. A fourth portion 434 of the clamping platform 43 passes through the second through hole 221. The fifth portion 435 of the clamping platform 43 passes through the third through hole 222. The clamping assembly 4 further comprises a second vacuum bellows 45 and a third vacuum bellows 46. The second vacuum bellows 45 is sleeved outside the fourth portion 434 of the clamping platform 43, and is used for sealing the second through hole 221, so that the working chamber formed after the first cavity 21 and the second cavity 22 are sealed can maintain a vacuum environment. The third vacuum bellows 46 is sleeved outside the fifth portion 435 of the clamping platform 43, and is used for sealing the third through hole 222, so that the working chamber formed after the first cavity 21 and the second cavity 22 are sealed can maintain a vacuum environment. In other embodiments, the first portion 431 and the second portion 432 of the clamping platform 43 may be integrally connected, so that the structures of the fourth portion 434 and the fifth portion 435 of the clamping platform 43 and the structure of the second cavity 22 are correspondingly adjusted.
The first clamping claw 41 and the second clamping claw 42 are respectively used for clamping both ends of the carrier film 400 (see fig. 2). The first clamping claw 41 and the second clamping claw 42 are respectively positioned at two sides of the fitting component 5 and are both slidably mounted on the clamping platform 43. Wherein the first clamping jaw 41 is slidably mounted to the first portion 431 of the clamping platform 43. Between the first clamping jaw 41 and the first part 431 of the clamping platform 43, a sliding rail structure is formed, the sliding direction of which is parallel to the second direction X, so that the first clamping jaw 41 can move in the second direction X relative to the first part 431 of the clamping platform 43. The second clamping jaw 42 is slidably mounted to the second portion 432 of the clamping platform 43. Between the second clamping jaw 42 and the second portion 432 of the clamping platform 43, a sliding rail structure is formed, the sliding direction of which is parallel to the second direction X, so that the second clamping jaw 42 can move in the second direction X relative to the second portion 432 of the clamping platform 43.
The gripper jaw drive assembly 44 is configured to drive the first gripper jaw 41 and the second gripper jaw 42 to move relative to each other in the second direction X. Gripper jaw drive assembly 44 includes a first gripper jaw drive 441, a second gripper jaw drive 442, a first gripper jaw transmission 443, and a second gripper jaw transmission 444. First gripper driving member 441 and second gripper driving member 442 are respectively located at both sides of second cavity 22 and are mounted on fixing frame 1. First gripper jaw transmission 443 is connected between first gripper jaw 41 and first gripper jaw driving member 441. Second gripper jaw transmission 444 is connected between second gripper jaw 42 and second gripper jaw drive 442. Wherein, the second cavity 22 is further provided with a fourth through hole 223 and a fifth through hole 224. The first gripper jaw transmission 443 passes through the fourth through hole 223. Second gripper jaw transmission 444 passes through fifth through-hole 224. The clamping assembly 4 further comprises a fourth vacuum bellows 47 and a fifth vacuum bellows 48. The fourth vacuum bellows 47 is sleeved outside the first clamping jaw transmission member 443 and is used for sealing the fourth through hole 223, so that a working chamber formed after the first cavity 21 and the second cavity 22 are sealed can maintain a vacuum environment. The fifth vacuum bellows 48 is sleeved outside the second gripper jaw transmission member 444 for sealing the fifth through hole 224, so that the working chamber formed after the first cavity 21 and the second cavity 22 are sealed can maintain a vacuum environment.
Optionally, the clamping assembly 4 is further used to keep the carrier film 400 in a tensioned state during the attachment of the curved cover plate 200 to the flexible screen 300. The attaching process is a process of attaching the curved cover plate 200 to the flexible screen 300. In this application, because first gripper jaw 41 and second gripper jaw 42 can drive the both ends of carrier film 400 and move in second direction X, consequently the both ends of carrier film 400 can be close to relatively or keep away from for carrier film 400 can keep the tensioning state in the laminating process, in order to guarantee the laminating quality of curved surface apron 200 and flexible screen 300.
It will be appreciated that the tensioning force of the carrier film 400 of the gripper assembly 4 remains substantially constant, allowing some float, but does not increase or decrease significantly while maintaining the tensioned state of the carrier film 400, thereby avoiding over-tensioning, under-tensioning, or immobilization of the carrier film 400.
First gripper driving member 441 may be a servo motor. Second gripper jaw drive 442 may be of the same type as first gripper jaw drive 441. At this time, first gripper jaw driving member 441 may control the movement speed, displacement, etc. of first gripper jaw 41 in stages, and second gripper jaw driving member 442 may control the movement speed, displacement, etc. of second gripper jaw 42 in stages. Through the clamping and tensioning of the first clamping claw 41 and the second clamping claw 42 at the two ends of the bearing film 400, the pre-bending profiling of the flexible screen 300 can be realized, and the fine control and adjustment are performed, so that the tensioning force of the bearing film 400 is stable, and the attaching quality of the flexible screen 300 and the curved surface cover plate 200 is higher.
In other embodiments, first gripper jaw drive 441 may be a conventional motor or cylinder.
Optionally, the first clamping jaw 41 comprises a first upper clamping jaw 411 and a first lower clamping jaw 412. The first upper jaw 411 and the first lower jaw 412 may be relatively moved in the first direction Z to perform opening or clamping, thereby releasing the carrier film 400 or fixing the carrier film 400. The first lower jaw 412 is slidably connected to the first upper jaw 411. Between the first upper jaw 411 and the first lower jaw 412, a rail structure is formed, which extends along the first direction Z.
Wherein the first clamping jaw 41 further comprises a cylinder 414. The air cylinder 414 is used to drive the first upper jaw 411 and the first lower jaw 412 to move away from and/or close to each other. In the present application, "a and/or B" includes three cases of the scheme a, the scheme B, and the schemes a and B. When the first upper jaw 411 and the first lower jaw 412 are separated from each other, it is possible to attach one end of the carrier film 400 to the first gripper 41 and detach one end of the carrier film 400 from the first gripper 41. The first upper jaw 411 and the first lower jaw 412 can grip one end of the carrier film 400 when they are close to each other.
In one embodiment, the cylinder 414 has bi-directional drive force. The air cylinder 414 can drive the first upper jaw 411 and the first lower jaw 412 away from and toward each other.
In another embodiment, the first clamping jaw 41 further comprises an elastic member 413. The elastic member 413 is used for generating an elastic force for clamping the first lower jaw 412 and the first upper jaw 411 to each other. The cylinder 414 is used to generate a driving force for moving the first lower jaw 412 and the first upper jaw 411 away from each other. When the air cylinder 414 is not operated, the first clamping claw 41 clamps the carrier film 400 when the elastic member 413 clamps the first lower clamping claw 412 and the first upper clamping claw 411 to each other. When the cylinder 414 is operated to drive the first lower jaw 412 and the first upper jaw 411 to move away from each other, the first clamping jaw 41 releases the carrier film 400.
Wherein, by replacing the elastic member 413 (for example, using a different type of spring), the first clamping jaw 41 has a different clamping force, so as to adapt to more types of carrier films 400 and attaching processes. In some embodiments, a torsion mechanism may be provided in the first clamping jaw 41 to reduce the force required by the air cylinder 414 to open the clamp (even if the first upper clamping jaw 411 and the first lower clamping jaw 412 are opened).
In yet another embodiment, the first clamping jaw 41 further comprises an elastic member 413. The elastic member 413 is used for generating an elastic force for separating the first lower jaw 412 and the first upper jaw 411 from each other. The cylinder 414 is used to generate a driving force for moving the first lower jaw 412 and the first upper jaw 411 toward each other. When the air cylinder 414 is not operated, the elastic member 413 makes the first lower jaw 412 and the first upper jaw 411 move away from each other, and the first clamping jaw 41 releases the carrier film 400. When the air cylinder 414 is operated to drive the first lower clamping jaw 412 and the first upper clamping jaw 411 to clamp each other, the first clamping jaw 41 clamps the carrier film 400.
In other embodiments, the relative movement between the first upper jaw 411 and the first lower jaw 412 may be achieved by other driving members. For example, a motor or a servo motor may be employed as the driving member. At this point, the driver is outside the second cavity 22.
Optionally, a plurality of positioning posts 4121 may be disposed on first lower jaw 412. The positioning posts 4121 are spaced apart from each other. The positioning posts 4121 are used to initially position the carrier film 400. The carrier film 400 is provided with a plurality of corresponding positioning holes. The first upper clamping jaw 411 is provided with a plurality of corresponding avoiding holes or avoiding grooves 4111. When the first lower clamping jaw 412 and the first upper clamping jaw 411 are clamped to each other, the positioning pillars 4121 are located in the avoiding holes or avoiding grooves 4111 in a one-to-one correspondence manner. Wherein, a plurality of dodging holes or dodging grooves 4111 can also be communicated with each other into a whole.
Optionally, the first upper jaw 411 includes an upper anti-slip layer (not shown) facing the first lower jaw 412. The first lower jaw 412 comprises a lower non-slip layer (not shown in the figure) facing the first upper jaw 411. The upper anti-slip layer and the lower anti-slip layer are used for increasing the friction coefficient between the first upper clamping jaw 411 and the first lower clamping jaw 412 and the carrier film 400 when the carrier film 400 is clamped by the upper clamping jaw and the lower clamping jaw, so that the carrier film 400 can be better fixed and clamped.
Optionally, the second clamping jaw 42 includes a second upper clamping jaw 421, a second lower clamping jaw 422, and driving members of the second upper clamping jaw 421 and the second lower clamping jaw 422. The first clamping claw 41 can be referred to for specific structural design, and details are not repeated here.
Optionally, clamp assembly 4 further includes a clamp platform drive assembly 49. The clamping platform drive assembly 49 is connected to the clamping platform 43 for driving the clamping platform 43 to move in the first direction Z. In this embodiment, since the clamping platform 43 can move in the first direction Z under the driving of the clamping platform driving assembly 49, and the first clamping claw 41 and the second clamping claw 42 slidably connected to the clamping platform 43 can carry two ends of the carrier film 400 to move in the second direction X, the carrier film 400 has the degrees of freedom in the first direction Z and the second direction X and in two directions, so as to better contact the attaching assembly 5, and realize bending and profiling, so as to improve the attaching quality of the flexible screen 300 and the curved cover plate 200. In addition, under the clamping and moving of the first clamping claw 41 and the second clamping claw 42, the profiling action of the carrier film 400 is active profiling, the controllability is stronger, and the precision is higher, so that the attaching quality of the flexible screen 300 and the curved cover plate 200 is higher. The first clamping claw 41 and the second clamping claw 42 have the degrees of freedom in the first direction Z and the second direction X, so that the clamping assembly 4 can move the two ends of the carrier film 400 more flexibly, and the tensioned state of the carrier film 400 is stably maintained in the process of attaching the flexible screen 300 to the curved cover plate 200.
Optionally, the clamping assembly 4 further comprises a first decoupling structure and a second decoupling structure. The first decoupling structure is connected between the first gripper jaw 41 and the gripper jaw drive assembly 44. The first decoupling structure is also connected between the first clamping jaw 41 and the clamping platform drive assembly 49. The first decoupling structure is used to enable the first gripper jaw 41 to move in a first direction Z relative to the gripper jaw drive assembly 44 and in a second direction X relative to the gripper platform drive assembly 49. The second decoupling structure is connected between the second clamping jaw 42 and the clamping jaw drive assembly 44 and the clamping platform drive assembly 49. The second decoupling structure is for enabling the second gripper jaw 42 to move 44 relative to the gripper jaw drive assembly in the first direction Z and to move 49 relative to the gripper platform drive assembly in the second direction X.
In this embodiment, the first decoupling structure and the second decoupling structure are used for relieving the interference of the gripper jaw driving assembly 44 and the gripper platform driving assembly 49 when driving the first gripper jaw 41 or the second gripper jaw 42, so that both the gripper jaw driving assembly 44 and the gripper platform driving assembly 49 can independently drive the first gripper jaw 41 or the second gripper jaw 42, and the attaching device 100 has high motion completion degree and good attaching quality.
The first decoupling structure and the second decoupling structure have multiple implementation modes. For example, in the embodiment shown in fig. 9, the first decoupling structure includes a first jaw base 415, a first jaw lower slide 416, and a first jaw side slide 417. The first upper jaw 411, the first lower jaw 412, and a driving member for driving the first upper jaw 411 and the first lower jaw 412 to move relatively are fixed to the first jaw base 415 relatively. In other words, when the first jaw base 415 moves, the first upper jaw 411, the first lower jaw 412 and the driving member for driving the first upper jaw 411 and the first lower jaw 412 to move relatively move synchronously are driven. The first jaw base 415 is slidably connected to a first portion 431 of the clamping platform 43. A first jaw lower slide 416 is formed between the first jaw base 415 and the clamp platform 43. The extension direction of the first jaw lower slide 416 is parallel to the second direction X. A first jaw side slide rail 417 is formed between the first jaw base 415 and the first jaw transmission 443. The extending direction of the first jaw-side slide rail 417 is parallel to the first direction Z.
At this time, when the clamping platform driving assembly 49 drives the clamping platform 43 to move in the first direction Z, the first jaw base 415 can move in the first direction Z relative to the first clamping jaw transmission 443, that is, the first clamping jaw 41 can move in the first direction Z independently of the first clamping jaw transmission 443. When the gripper jaw driving assembly 44 drives the first gripper jaw base 415 to move in the second direction X through the first gripper jaw transmission 443, the first gripper jaw base 415 can move in the second direction X relative to the attaching platform 43, that is, the first gripper jaw 41 can move independently of the attaching platform 43 in the second direction X. Therefore, the driving mechanism of the first gripper jaw 41 in the first direction Z and the driving mechanism in the second direction X can be used in cooperation with each other without interference, and the driving mechanism has a simple structure and a low cost.
The second decoupling structure may be designed by referring to the first decoupling structure, and details are not described here.
In other embodiments, the first decoupling structure and the second decoupling structure may have other implementations, which are not strictly limited in this application.
Optionally, the clamping platform drive assembly 49 includes an adjustment platform 491, a clamping platform drive member 492, and a clamping platform drive member 493. The adjustable platform 491 is also called a UVW platform, and the adjustable platform 491 can move in the second direction X and the third direction and can rotate around the first direction Z. The adjustment platform 491 is mounted on the base 11 of the fixing frame 1. The clamping platform driving member 493 is mounted on the adjustment platform 491. The clamping platform driving member 493 may be a servo motor, a common motor, or an air cylinder. Clamping platform drive 492 includes a first wedge block 4921, a second wedge block 4922, and one or more sets of guides 4923. The first wedge 4921 is connected to the clamping platform 43, for example to the third portion 433 of the clamping platform 43. The second wedge 4922 is attached to an adjustment platform 491. The second wedge 4922 cooperates with the inclined surface of the first wedge 4921. The clamping platform drive 493 is coupled to the second wedge 4922 to drive the second wedge 4922 to move in a direction perpendicular to the first direction Z (e.g., the second direction X), and the second wedge 4922 drives the first wedge 4921 to move in the first direction Z to move the clamping platform 43 in the first direction Z. One or more sets of guides 4923 are connected between clamping platform 43 and adjustment platform 491 for limiting movement of clamping platform 43 relative to adjustment platform 491 in first direction Z.
In this embodiment, since the adjustment platform 491 can rotate around the first direction Z, the clamping platform 43 can deflect at an angle, so that the flexible screen 300 can compensate for the deflection angle when aligning with the curved cover plate 200, thereby achieving higher alignment accuracy.
In other embodiments, the clamping platform driving assembly 49 may drive the clamping platform 43 to move in the first direction Z through other structures. This is not strictly limited in this application.
Referring to fig. 10, fig. 10 is a schematic partial structural view of the bonding apparatus 100 shown in fig. 1. Fig. 10 mainly includes a fitting assembly 5 structure of the fitting apparatus 100.
The attaching assembly 5 includes a first slider 51, a second slider 52 and an attaching pad 53. The first slider 51 and the second slider 52 are aligned in the second direction X, and can approach and move away from each other. The first slider 51 and the second slider 52 may be close to each other in the second direction X to a closed state, or may be away from each other in the second direction X to an open state. The second direction X is perpendicular to the first direction Z. The pad 53 is made of an elastic material. Conformable pad 53 may deform when subjected to a force. The fit pad 53 is located on the side of the first slider 51 and the second slider 52 facing the mount assembly 3. The fit pad 53 extends from a side of the first slider 51 away from the second slider 52 to a side of the second slider 52 away from the first slider 51. At this time, the attaching pad 53 covers the attaching area of the first slider 51 and the second slider 52 toward the mount assembly 3. The attaching pad 53 is used for supporting the flexible screen 300 to be stacked and attached to the curved cover plate 200 along the first direction Z.
In this embodiment, the attaching assembly 5 may attach the middle region of the flexible screen 300 and the middle region of the curved cover plate 200 through the attaching pad 53 when the first slider 51 and the second slider 52 are in the close state, and attach the edge region of the flexible screen 300 and the edge region of the curved cover plate 200 through the attaching pad 53 when the first slider 51 and the second slider 52 are in the open state, so that the flexible screen 300 and the curved cover plate 200 are attached in stages, and the attaching sequence is first from the middle to the two sides, thereby reducing risks of occurrence of bubbles, cracks, wrinkles and other defects, so that the attaching quality of the curved cover plate 200 and the flexible screen 300 is better, and the yield of the screen formed after the curved cover plate 200 and the flexible screen 300 are attached is higher.
Because laminating subassembly 5 supports flexible screen 300 through laminating pad 53, laminating pad 53 adopts elastic material, not only can transmit the holding power of first slider 51 and second slider 52 for flexible screen 300 and curved surface capping through laminating pad 53 for laminate, laminating pad 53's cushioning effect and indirect supporting effect make flexible screen 300 can remain stable position and state in the laminating in-process moreover, make the laminating quality of flexible screen 300 and curved surface apron 200 better.
Referring to fig. 11, fig. 11 is a schematic view illustrating a cover plate structure according to an embodiment of the present disclosure. The middle area 2001 of the curved cover plate 200 is a flat portion. The edge region 2002 of the curved cover plate 200 includes curved portions at the ends. In one embodiment, the curved portion has a bend angle greater than or equal to 60 °. This example is used as an example for the present application.
The edge region 2002 of the curved cover plate 200 may also include a flat portion that connects between the middle region 2001 of the curved cover plate 200 and the curved portion of the edge region 2002. The bending angle of the curved cover plate 200 is the angle between the tangent plane at the end of the edge area 2002 and the plane of the middle area 2001, the angle is located on the side of the plane of the middle area 2001 facing the edge area 2002, and the tangent plane at the end of the edge area 2002 is away from the plane area 2001. In the embodiment shown in fig. 11, the curved cover plate 200 has a curvature angle of about 95 °. In other embodiments, the curved cover plate 200 may also have a bending angle of 60 °, 70 °, 80 °, 81.2 °, 85 °, 90 °, 100 °, 105 °, and the like. It is understood that the curved angle of the curved cover plate 200 may be any angle within the range.
Continuing to refer to FIG. 10, the laminating assembly 5 further includes a laminating platform 54 and a slider drive assembly 55. The first slider 51 and the second slider 52 are slidably mounted on the attaching platform 54. The slider driving assembly 55 serves to drive the first slider 51 and the second slider 52 toward and away from each other. The slider driving assembly 55 is used for driving the first slider 51 and the second slider 52 to move in the second direction X. Because the first slider 51 and the second slider 52 are both slidably mounted on the attaching platform 54, the sliding directions of the first slider 51 and the second slider 52 can be more smoothly and accurately controlled through the attaching platform 54, so that the attaching quality of the flexible screen 300 and the curved cover plate 200 is ensured.
The first slider 51, the second slider 52 and the attaching platform 54 may be directly connected or indirectly connected. This embodiment is described by taking an indirect connection as an example. Referring to fig. 1 and 10, the first slider 51 and the second slider 52 are located inside the second cavity 22, and the bonding platform 54 and the slider driving assembly 55 are located outside the second cavity 22. The gluing assembly 5 further comprises a first slider transmission 56 and a second slider transmission 57. The first slider transmission member 56 is connected between the first slider 51 and the attachment platform 54. A second slider drive 57 is connected between the second slider 52 and the application platform 54.
In this embodiment, since the slider driving assembly 55 can be located outside the second cavity 22, the space of the second cavity 22 can be reduced, and the cost of the vacuum environment of the bonding apparatus 100 can be reduced, and it is not necessary to require the slider driving assembly 55 to work normally in the vacuum environment, the requirements on the components in the slider driving assembly 55 are low, and it is enough to adopt a driving member with low cost to meet the driving requirements, so the overall cost of the bonding apparatus 100 is low.
Specifically, as shown in fig. 10, the first slider transmission member 56 includes a fixed portion 561, a sliding portion 562, and a connecting portion 563 connected between the fixed portion 561 and the sliding portion 562. The fixed portion 561 of the first slider transmission member 56 is located inside the second cavity 22, and the first slider 51 is fixedly connected to the fixed portion 561 of the first slider transmission member 56. The sliding portion 562 of the first slider drive 56 is located outside of the second cavity 22 and is slidably coupled to the engaging platform 54. The sliding portion 562 of the first slider transmission member 56 and the attaching platform 54 form a sliding rail structure, and the extending direction of the sliding rail structure is parallel to the second direction X.
The second cavity 22 is provided with a sixth through hole 225. One end of the connecting portion 563 of the first slider transmission member 56 is located inside the second cavity 22 and connected to the fixing portion 561 of the first slider transmission member 56, and the other end thereof extends to the outside of the second cavity 22 through the sixth through hole 225 and is connected to the sliding portion 562 of the first slider transmission member 56. Conformable assembly 5 further includes a sixth vacuum bellows 58. The sixth vacuum bellows 58 is sleeved outside the connecting portion 563 of the first slider transmission member 56, and is configured to seal the sixth through hole 225, so that the working chamber formed after the first cavity 21 and the second cavity 22 are sealed can maintain a vacuum environment.
The second slider transmission member 57 includes a fixed portion 571, a sliding portion 572, and a connecting portion 573 connected between the fixed portion 571 and the sliding portion 572. The fixing portion 571 of the second slider transmission member 57 is located inside the second cavity 22, and the second slider 52 is fixedly connected to the fixing portion 571 of the second slider transmission member 57. The sliding portion 572 of the second slider transmission member 57 is located outside the second cavity 22 and is slidably connected to the engaging platform 54. The sliding portion 572 of the second slider transmission member 57 and the attaching platform 54 form a sliding track structure, and the extending direction of the sliding track structure is parallel to the second direction X.
The second cavity 22 is provided with a seventh through hole 226. One end of the connecting portion 573 of the second slider transmission member 57 is located inside the second cavity 22 and connected to the fixing portion 571 of the second slider transmission member 57, and the other end thereof extends outside the second cavity 22 through the seventh through hole 226 and is connected to the sliding portion 572 of the second slider transmission member 57. Conformable assembly 5 further includes a seventh vacuum bellows 59. The seventh vacuum bellows 59 is disposed outside the connecting portion 573 of the second slider transmission member 57 and seals the seventh through hole 226, so that the working chamber formed by sealing the first cavity 21 and the second cavity 22 can maintain a vacuum environment.
It will be appreciated that the fixed portion 561 of the first slider transmission member 56 can be fixed to the second cavity 22 by a slide rail structure and can be moved by the connecting portion 563 of the first slider transmission member 56. The slide rail structure includes degrees of freedom in a first direction Z and a second direction X. The fixing portion 571 of the second slider transmission member 57 may be fixed to the second cavity 22 by a slide rail structure and may be moved by the connection portion 573 of the second slider transmission member 57. The slide rail structure includes degrees of freedom in a first direction Z and a second direction X. In this case, the stability of the first slider 51 and the second slider 52 is better.
It should be understood that the embodiment shown in fig. 10 is only a schematic structural diagram of the first slider transmission member 56 and the second slider transmission member 57 in one embodiment, and the first slider transmission member 56 and the second slider transmission member 57 may have other structures, which is not limited to this embodiment.
The slider driving assembly 55 includes a first slider driving member 551 and a second slider driving member 552. The first slider driving member 551 is used for driving the first slider 51 to move along the second direction X. For example, a first slider drive 551 may be mounted to the abutment platform 54. The first slider driving member 551 is connected to the driving portion 562 of the first slider transmission member 56, and drives the first slider 51 to move through the first slider transmission member 56. The second slider driver 552 is used to drive the second slider 52 to move in the second direction X. For example, a second slider drive 552 may be mounted to the conformable platform 54. The second slider driving member 552 is connected to the driving portion 572 of the second slider transmission member 57 for moving the second slider 52 via the second slider transmission member 57.
In this embodiment, since the first slider 51 is driven by the first slider driving member 551 and the second slider 52 is driven by the second slider driving member 552, the first slider 51 and the second slider 52 can be operated independently of each other, for example, the first slider 51 and the second slider 52 can be moved simultaneously, sequentially, or one can be moved while the other is not moved. Therefore, the movement of the first slider 51 and the second slider 52 is more flexible, and the step of attaching the flexible screen 300 and the curved cover 200 of the attaching apparatus 100 is more flexible and diversified.
The first slider driving member 551 and the second slider driving member 552 may employ servo motors. The servo motor adopts a closed-loop feedback system and has accurate position precision, so that the positions and the moving speeds of the first slider 51 and the second slider 52 can be accurately controlled, the position precision of the first slider 51 and the second slider 52 is high, and the reliability of the laminating process of the laminating device 100 is ensured. Moreover, a feedback system of the servo motor can also respond in time, and the first slider 51 and the second slider 52 push the flexible screen 300 to be attached to the curved cover plate 200, so that the attaching pressure between the flexible screen 300 and the curved cover plate 200 is adjusted in time, and the attaching precision of the attaching device 100 is higher. In other embodiments, the first slider drive 551 and the second slider drive 552 may be implemented by conventional motors or pneumatic cylinders. In addition, the first slider driving member 551 and the second slider driving member 552 can also be set to the initial positions by the servo motor, so that the first slider 51 and the second slider 52 can accurately move back to the initial positions when approaching to the close state, thereby ensuring the attaching precision in the next attaching process.
In the present application, the positioning of fit platform 54 may be designed in a variety of ways.
For example, in one embodiment, the conformable platform 54 may be a fixed platform. For example, the conformable platform 54 may be mounted to the fixture 1, or be part of the fixture 1. At this time, the first slider 51 and the second slider 52 have a degree of freedom in the second direction X. In the process of attaching the flexible screen 300 to the curved cover plate 200, the first clamping claw 41 and the second clamping claw 42 of the clamping assembly 4 can move in the first direction Z and the second direction X, so that the first clamping claw 41 and the second clamping claw 42 drive the two ends of the carrier film 400 to approach or be away from the attaching assembly 5, and the flexible screen 300 fixed on the carrier film 400 is close to or is away from the attaching pad 53 of the attaching assembly 5; the mounting member 3 can move in the first direction Z to make the mounting member 3 bring the curved cover plate 200 close to or away from the flexible screen 300.
In another embodiment, the docking platform 54 is a movable platform, and the docking platform 54 is movable in the first direction Z. For example, as shown in FIG. 10, conformable assembly 5 further includes a conformable platform drive assembly 510. Conformable station drive assembly 510 is used to drive conformable station 54 in a first direction Z. At this time, the first slider 51 and the second slider 52 can drive the attaching pad 53 to move along the first direction Z under the driving of the attaching platform driving assembly 510, so as to support the flexible screen 300 to move along the first direction Z, and thus the attaching step of the attaching device 100 has higher flexibility and is more diversified. Further, when the attaching platform 54 can move in the first direction Z, the mounting base 31 in the mounting unit 3 can be fixed in the first direction Z, and can have a degree of freedom in the first direction Z, and the arrangement manner of the mounting base 31 can be more diversified. In addition, when the attaching platform 54 can move in the first direction Z, the first clamping claw 41 and the second clamping claw 42 of the clamping assembly 4 may not have the degree of freedom in the first direction Z, and the movement motion of the attaching platform 54 in the first direction Z is matched with the movement motion of the first clamping claw 41 and the second clamping claw 42 in the second direction X, so that the profiling motion of the carrier film 400 and the flexible screen 300 is realized.
The bonding platform driving assembly 510 includes a bonding platform driving member 5101, a third wedge 5102, a fourth wedge 5103, and one or more sets of guiding members 5104. A third wedge 5102 connects the engaging platform 54. The fourth wedge 5103 is connected to the support platform 14 of the fixing frame 1. The fourth wedge 5103 is engaged with the inclined surface of the third wedge 5102. The conformable platform drive 5101 may be mounted to the support platform 14. The laminating platform drive 5101 is connected to the fourth wedge 5103 to drive the fourth wedge 5103 to move in a direction perpendicular to the first direction Z (e.g., the second direction X), and the fourth wedge 5103 drives the third wedge 5102 to move in the first direction Z to move the laminating platform 54 in the first direction Z. One or more sets of guides 5104 are coupled between the conformable platform 54 and the support platform 14 for limiting movement of the conformable platform 54 relative to the support platform 14 in the first direction Z.
In the present application, the structural design of the attachment platform 54 can be implemented in a variety of ways:
as shown in FIG. 10, in one embodiment, the side of the conformable platform 54 supporting the first and second slides 51, 52 is fixed to the side for coupling to conformable platform drive assembly 510.
In another embodiment, the side of the conformable platform 54 supporting the first and second slides 51, 52 and the side for connecting the conformable platform drive assembly 510 may be movable relative to each other. Specifically, the method comprises the following steps:
referring to fig. 12, fig. 12 is a schematic structural view of another embodiment of the bonding assembly 5 in the structure shown in fig. 10. Most technical contents of the attaching assembly 5 in this embodiment that are the same as those of the attaching assembly 5 in the foregoing embodiment are not described again.
The bonding platform 54 includes an upper platform 541, a lower platform 542, and an elastic member 543. The attaching platform 54 is formed on the upper platform 541 for supporting one side of the first slider 51 and the second slider 52. The first slider 51 and the second slider 52 are mounted to the upper stage 541. The first slider 51 is slidably mounted to the upper stage 541 by a first slider transmission member 56. The second slider 52 is slidably mounted to the lower platform 542 via a second slider drive 57. The lower stage 542 is located on a side of the upper stage 541 remote from the first slider 51 and the second slider 52. One side of the conformable platform 54 for connecting to conformable platform drive assembly 510 is formed in lower platform 542. Lower platform 542 is coupled to conformable platform drive assembly 510. The elastic member 543 is connected between the lower platform 542 and the upper platform 541, so that the upper platform 541 and the lower platform 542 can move relatively. The elastic member 543 may include a plurality of elastic bodies arranged to be spaced apart from each other. The elastic body may be a spring (as shown in fig. 12), rubber, or the like.
In this embodiment, because the elastic member 543 is disposed between the upper platform 541 and the lower platform 542, the elastic member 543 is stressed to deform, so that in the process of attaching the flexible screen 300 to the curved cover plate 200, the attaching pressure between the flexible screen 300 and the curved cover plate 200 is transmitted to the elastic member 543 through the attaching pad 53, the first slider 51, the second slider 52 and the upper platform 541, the elastic member 543 can adapt to the attaching pressure, so that the upper platform 541 moves or tilts according to the attaching condition of the flexible screen 300 and the curved cover plate 200, thereby further optimizing the attaching condition of the flexible screen 300 and the curved cover plate 200, and further improving the attaching quality of the two.
Wherein the slider driving assembly 55 is mounted to the upper stage 541. That is, the first and second slider driving members 551 and 552 are mounted on the upper stage 541. At this time, the first and second slider driving members 551 and 552 move along with the upper stage 541. The first and second slider drivers 551 and 552 may be air cylinders. The cylinder has a smaller volume and a lower weight, which is advantageous for increasing the flexibility of the upper platform 541. In other embodiments, the first slider drive 551 and the second slider drive 552 may be servo motors, common motors, or the like.
Referring to fig. 13, fig. 13 is a schematic structural view of a bonding assembly 5 in the structure shown in fig. 10 according to still another embodiment. Most technical contents of the attaching assembly 5 in this embodiment that are the same as those of the attaching assembly 5 in the foregoing embodiment are not described again.
In this embodiment, the slide drive assembly 55 includes a slide drive member. The slider driving member is mounted on the upper stage 541. The slider driving unit is used to drive the first slider 51 and the second slider 52. The slider driving part may be located between the first slider 51 and the second slider 52. In this embodiment, the number of the slider driving members is smaller than that in the foregoing embodiment, so that the load of the upper platform 541 is smaller, and the upper platform 541 can more flexibly adapt to the bonding stress between the flexible screen 300 and the curved cover plate 200, so as to improve the bonding quality.
Wherein the slider drive assembly 55 further comprises a drive transmission member (not shown) by which the slider drive member can drive the first and second sliders 51, 52. In one implementation, the driving shaft of the slider driving member moves in a third direction, the third direction is perpendicular to the first direction Z and the second direction X, and the driving transmission member connects the driving shaft of the slider driving member with the first slider 51 and the second slider 52 and converts the power of the third direction into the power of the second direction X, so that the slider driving member can drive the first slider 51 and the second slider 52. It will be appreciated that the drive transmission member may be of various constructions and the construction of the drive transmission member is not strictly limited in this application.
Referring to fig. 14, fig. 14 is a schematic structural view of a bonding assembly 5 in the structure shown in fig. 10 according to still another embodiment. Most technical contents of the attaching assembly 5 in this embodiment that are the same as those of the attaching assembly 5 in the foregoing embodiment are not described again.
The slider drive assembly 55 includes a first slider drive 551, a first drive transmission 553, a second slider drive 552, and a second drive transmission 554. The first slider drive 551 is mounted to the lower platform 542. The first drive transmission 553 is slidably mounted to the lower platform 542. Between the first driving transmission member 553 and the lower platform 542, a sliding track structure is formed, which extends along the second direction X. The first slider drive 551 is for driving the first drive transmission 553 to move in the second direction X. The first slider transmission member 56 is slidably connected to the first driving transmission member 553, and a sliding rail structure is formed therebetween, and extends along the first direction Z. A second slider drive 552 is mounted to the lower platform 542. A second drive transmission 554 is slidably mounted to the lower platform 542. The second drive transmission member 554 and the lower platform 542 form a sliding track structure extending along the second direction X. The second slider drive 552 is for driving the second drive transmission 554 to move in the second direction X. The second slider transmission member 57 is slidably connected to the second driving transmission member 554, and a sliding rail structure is formed between the second driving transmission member and the second driving transmission member, and the sliding rail structure extends along the first direction Z.
When the first slider driving part 551 drives the first driving transmission member 553 to move in the second direction X, the first driving transmission member 553 pushes the first slider transmission member 56, thereby moving the first slider 51 in the second direction X. When the second slider driving member 552 drives the second driving transmission member 554 to move in the second direction X, the second driving transmission member 554 pushes the second slider transmission member 57, thereby moving the second slider 52 in the second direction X. When the upper platform 541 moves relative to the lower platform 542, the first slider transmission member 56 can move relative to the first driving transmission member 553, and the second slider transmission member 57 can move relative to the second driving transmission member 554, so that the first slider 51 and the second slider 52 can move along with the upper platform 541, thereby realizing self-adaptation.
In this embodiment, since the slider driving assembly 55 is mounted on the lower platform 542, the load of the upper platform 541 is small, and the upper platform 541 can more flexibly adapt to the bonding stress between the flexible screen 300 and the curved cover 200, so as to improve the bonding quality.
It is to be understood that, in the description section above regarding the structural design of fit platform 54, fit platform 54 is mainly taken as an example of a movable platform (i.e., a solution in which fit assembly 5 includes fit platform driving assembly 510). In the embodiment where the attaching platform 54 is a fixed platform, the lower platform 542 of the attaching platform 54 is a fixed platform, and the lower platform 542 may be fixed to the fixing frame 1 or be a part of the fixing frame 1.
In the embodiment of the present application, the shape of the pad 53 matches the shape of the first slider 51 and the second slider 52. The design basis of the fit pad 53, the second slider 52 and the second slider 52 is: the shape of the outer surface of the portion of the first slider 51, the bonding pad 53, the carrier film 400 and the flexible screen 300 corresponding to one of the edge regions of the curved cover plate 200 after being stacked is the same as the shape of the inner surface of the edge region of the curved cover plate 200; the shape of the outer surface of the portion of the second slider 52, the bonding pad 53, the carrier film 400, and the flexible screen 300 corresponding to the other edge region of the curved cover 200 after being stacked is the same as the shape of the inner surface of the edge region of the curved cover 200. At this time, the flexible screen 300 can be well attached to the inner surface of the curved cover 200, thereby achieving complete attachment. That is, the shapes of the first and second sliders 51 and 52, the bonding pad 53, and the carrier film 400 are designed to be similar to the shape of the edge region of the curved cover plate 200.
The first slider 51, the second slider 52 and the bonding pad 53 have various structures. Specifically, the method comprises the following steps:
referring to fig. 15 to 17, fig. 15 is a schematic partial structure view of the attaching assembly 5 shown in fig. 10, fig. 16 is an exploded view of the structure shown in fig. 15, and fig. 17 is a schematic structural view of the structure shown in fig. 15 in another use state. Fig. 15 illustrates the structure of the first slider 51, the second slider 52 and the bonding pad 53 of the bonding assembly 5.
Optionally, the first slider 51 includes a first supporting surface 511, a first transition surface 512 and a first side surface 513 connected in sequence. The first transition surface 512 smoothly connects the first support surface 511 and the first side surface 513. The second slider 52 includes a second supporting surface 521, a second transition surface 522 and a second side surface 523, which are sequentially connected. The second transition surface 522 smoothly connects the second supporting surface 521 and the second side surface 523. The first and second support surfaces 511, 521 are both disposed facing the mounting assembly 3 (see fig. 1). The first side surface 513 and the second side surface 523 are disposed opposite to each other and both are recessed toward each other. Conformable pad 53 contacts first transition surface 512, first support surface 511, second support surface 521 and second transition surface 522.
In this embodiment, since the first side surface 513 and the second side surface 523 are recessed toward each other, that is, the first side surface 513 and the second side surface 523 are waisted, a portion corresponding to the first transition surface 512 forms a vertex angle with a smooth surface, and a portion corresponding to the second transition surface 522 forms a vertex angle with a smooth surface. In the process that the first slider 51 and the second slider 52 are away from each other to the open state, the vertex angle formed by the first slider 51 and the second slider 52 can be abutted against the flexible screen 300 through the attaching pad 53 and the carrier film 400, so that the edge area of the flexible screen 300 is attached to the edge area of the curved cover plate 200. Moreover, the vertex angles of the first slider 51 and the second slider 52 can be adapted to the bending angle of the edge area of the curved cover plate 200, so that the attaching device 100 can be better applied to the attaching environment of the curved cover plate 200 with a large bending angle.
As shown in fig. 15, when the first slider 51 and the second slider 52 are close to each other to a closed state, the first supporting surface 511 forms a supporting region of the first slider 51, the second supporting surface 521 forms a supporting region of the second slider 52, and the first supporting surface 511 and the second supporting surface 521 jointly support the attaching pad 53, so that the middle region of the flexible screen 300 supported by the attaching pad 53 is attached to the middle region of the curved cover plate 200. As shown in fig. 17, when the first slider 51 and the second slider 52 are moved away from each other to an open state, the first supporting surface 511 and the first transition surface 512 together form a supporting region of the first slider 51, the second supporting surface 521 and the second transition surface 522 together form a supporting region of the second slider 52, and the first supporting surface 511, the first transition surface 512, the second supporting surface 521 and the second transition surface 522 together support the attaching pad 53, so that the edge region of the flexible screen 300 is supported by the attaching pad 53 to be attached to the edge region of the curved cover plate 200.
Referring to fig. 15 to 17 again, the pad 53 includes a first side portion 531, a second side portion 532, and a middle portion 533 between the first side portion 531 and the second side portion 532. As shown in fig. 17, when the first slider 51 and the second slider 52 are moved away from each other to an open state, the first side portion 531 faces the first side surface 513, the second side portion 532 faces the second side surface 523, and the middle portion 533 faces the first transition surface 512, the first supporting surface 511, the second supporting surface 521 and the second transition surface 522.
In this embodiment, middle portion 533 of conformable pad 53 can be used to support carrier film 400 and flexible screen 300. Since the first side portion 531 faces the first side surface 513 and the second side portion 532 faces the second side surface 523 when the first slider 51 and the second slider 52 are away from each other to the open state, the middle portion 533 can maintain a state of covering the support areas of the first slider 51 and the second slider 52 in the attaching process, so that the flexible screen 300 can be stably supported, and the attaching quality of the flexible screen 300 and the curved cover plate 200 is better.
Wherein, fit pad 53 may have a variety of shapes when in a natural state. For example, as shown in FIG. 17, conformable pad 53 may be a contoured pad. That is, the bonding pad 53 is formed by opening the mold. The shape of the silicone pad 53 in the natural state is adapted to the shape of the outer side surface of the first slider 51 and the second slider 52 in the closed state. For example, when the silicone pad 53 is in a natural state: the shape of the surface of the silica gel pad 53, which is used for contacting the first transition surface 512 (the first slider 51 and the second slider 52 are in a closed state), is matched with that of the first transition surface 512, and the two can be mutually attached; the shape of the surface of the silicone pad 53 for contacting the first transition surface 512 (the first slider 51 and the second slider 52 are in the closed state) is matched with the shape of the second transition surface 522, and the two surfaces can be attached to each other. Of course, since the silicone pad 53 is made of an elastic material, the shape of the surface of the silicone pad 53 contacting the first transition surface 512 (the first slider 51 and the second slider 52 are in the closed state) may also be slightly different from that of the first transition surface 512, and the shape of the surface of the silicone pad 53 contacting the first transition surface 512 (the first slider 51 and the second slider 52 are in the closed state) may be slightly different from that of the second transition surface 522.
In other embodiments, conformable pad 53 may be in a flattened configuration when in its natural state (see FIG. 25 in the examples below).
Alternatively, conformable pad 53 may be formed of silicone, rubber, Thermoplastic Elastomer (TPE), or the like. The rubber material includes, but is not limited to, Thermoplastic Polyurethanes (TPU). The shore hardness of fit pad 53 may be between 10 degrees and 80 degrees, such as shore 15 degrees, shore 20 degrees, shore 25 degrees, shore 30 degrees, shore 35 degrees, shore 40 degrees, shore 42 degrees, shore 42.5 degrees, shore 60 degrees, and the like.
Alternatively, referring to fig. 11 and 16, the length of the attachment surface 2003 of the curved cover plate 200 in the second direction X is the first length L1. When the first slider 51 and the second slider 52 are in the closed state, the maximum length of the part of the attachment pad 53 corresponding to the first transition surface 512, the part of the attachment pad 53 corresponding to the second transition surface 522, and the outer surface in the second direction X is the second length L2. The first length L1 is greater than the second length L2. The specific dimensions of the first slider 51, the second slider 52 and the fit pad 53 are designed according to the specific product form of the curved cover plate 200 and the flexible screen 300.
It is understood that the area of the contact area between the middle portion 533 of the fit pad 53 and the first and second support surfaces 511 and 521 is increased during the process of transforming the first and second sliders 51 and 52 from the closed state to the open state, which can be generally realized by the following embodiments:
in one embodiment, referring to fig. 15 and 17, during the process of transforming the first slider 51 and the second slider 52 from the closed state to the open state, the first side portion 531 and the second side portion 532 of the fit pad 53 are deformed, so that the two ends of the middle portion 533 of the fit pad 53 connecting the first side portion 531 and the second side portion 532 move towards the first transition surface 512 and the second transition surface 522, thereby increasing the area of the area where the middle portion 533 contacts the first slider 51 and the second slider 52 (where the area includes the area facing the gap between the first slider 51 and the second slider 52). In this embodiment, the middle portion 533 of the attaching pad 53 is not deformed or hardly deformed, so that the middle portion 533 of the attaching pad 53 can be reliably supported by the flexible screen 300, the attaching of the flexible screen 300 and the curved cover plate 200 is in place, the problem of the attaching being not in place due to the fact that the size of the middle portion 533 of the attaching pad 53 is too large in deformation is avoided, and the attaching quality of the flexible screen 300 and the curved cover plate 200 is better.
In the present embodiment, as shown in fig. 15, when the first slider 51 and the second slider 52 are close to each other to the close state, the first side portion 531 faces the first side surface 513, the second side portion 532 faces the second side surface 523, and the middle portion 533 faces a partial region of the first side surface 513, a partial region of the first transition surface 512, a partial region of the first support surface 511, a partial region of the second support surface 521, a partial region of the second transition surface 522, and a partial region of the second side surface 523.
The middle portion 533 is provided with a reinforcing layer 534 on one surface facing the first slider 51 and the second slider 52 (hereinafter referred to as a bottom surface of the middle portion 533), so that the tensile strength of the middle portion 533 is greater than the tensile strength of the first side portion 531 and greater than the tensile strength of the second side portion 532. At this time, the deformation region of the attaching pad 53 is controlled at the first and second side portions 531 and 532. Specifically, in the process that the first slider 51 and the second slider 52 are away from each other to the open state, the first side portion 531 and the second side portion 532 having smaller tensile strength are stretched, the middle portion 533 having larger tensile strength is not deformed or is deformed a little, one end of the middle portion 533 connected to the first side portion 531 moves from a position facing the first side surface 513 to a position close to the position facing the first transition surface 512, one end of the middle portion 533 connected to the second side portion 532 moves from a position facing the second side surface 523 to a position close to the position facing the second transition surface 522, and the middle portion 533 can support the edge region of the flexible screen 300 to be attached to the edge region of the cover plate with high precision.
The reinforcing layer 534 may be made of a flexible material with high tensile strength, such as a metal material or a fabric. The reinforcing layer 534 may be made of a material with a small friction coefficient, so that the relative movement between the middle portion 533 and the first and second sliders 51 and 52 is smooth, and the resistance of the first and second sliders 51 and 52 in the process of being away from each other is small, thereby reducing the required driving force of the slider driving assembly 55, and reducing the energy consumption of the attaching apparatus 100.
In another embodiment, referring to fig. 18 and 19 together, fig. 18 is a schematic structural view of a portion of the structure of the attaching assembly 5 shown in fig. 15 in another embodiment, and fig. 19 is a schematic structural view of the structure shown in fig. 18 in another using state. Most technical contents of the attaching assembly 5 shown in this embodiment that are the same as the attaching assembly 5 of the previous embodiment are not described again.
In the process of transforming the first slider 51 and the second slider 52 from the closed state to the open state, the whole of the fit pad 53 is deformed, that is, the middle portion 533, the first side portion 531 and the second side portion 532 of the fit pad 53 are deformed. At this time, the entire thickness of the attachment pad 53 becomes thin and the area becomes large, so that both ends of the middle portion 533 of the attachment pad 53 connecting the first and second side portions 531 and 532 move toward the first and second transition surfaces 512 and 522, thereby increasing the area of the region where the middle portion 533 contacts the first and second sliders 51 and 52. At this time, the end of the middle portion 533 connected to the first side portion 531 may completely face the first transition surface 512, or may partially face the first transition surface 512 and partially face the first side surface 513. The end of the middle portion 533 connected to the second side portion 532 may face the second transition surface 522 completely, or may face the second transition surface 522 partially and face the second side surface 523 partially.
One surface of the middle portion 533 facing the first slider 51 and the second slider 52 (i.e., the bottom surface of the middle portion 533) is provided with a lubricating layer 535, and the lubricating layer 535 is made of a lubricating material. At this time, since the regions of the adhesion pad 53 contacting the first slider 51 and the second slider 52 are concentrated on the middle portion 533 of the adhesion pad 53 and these regions are provided with the lubricating layer 535, the deformation resistance of the adhesion pad 53 in the process of the first slider 51 and the second slider 52 being away from each other is smaller, which is advantageous for ensuring the smooth proceeding of the adhesion process. Wherein the lubricating material may be a lubricating oil, a grease or a solid lubricant. In one embodiment, the side of the first side 531 facing the first slider 51 and the side of the second side 532 facing the second slider 52 are also provided with a lubricating layer 535.
In yet another embodiment, the middle portion 533 of conformable pad 53 is deformed and the first and second side portions 531, 532 are not deformed. For example, the thickness of the middle portion 533 of the fit pad 53 is thinned to have a larger area, so that the area of the region where the middle portion 533 is in contact with the first slider 51 and the second slider 52 is larger. In this embodiment, when the first slider 51 and the second slider 52 approach each other to the close state, the first side portion 531 faces the first side surface 513, the second side portion 532 faces the second side surface 523, and the middle portion 533 faces the first transition surface 512, the first supporting surface 511, the second supporting surface 521, and the second transition surface 522.
Referring to fig. 20, fig. 20 is a schematic structural view of the structure shown in fig. 15 at another angle.
Optionally, the first side 531 is fixed to the first side 513. The second side 532 is fixed to the second side 523. When the first slider 51 and the second slider 52 are brought close to each other to the closed state, the fit pad 53 is in a natural state or a tensioned state. Wherein, when the attaching pad 53 is in a natural state, no wrinkle is formed. At this point, conformable pad 53 has a flat (meaning a support surface without sharp bumps or pits) support surface. When the first slider 51 and the second slider 52 are moved away from each other to an opened state, the fit pad 53 is in a tensioned state. At this time, the bonding pad 53 has a flat supporting surface.
In this embodiment, since the first side 531 of the bonding pad 53 is fixed to the first slider 51, and the second side 532 is fixed to the second slider 52, the bonding pad 53 does not shift in the process of separating the first slider 51 and the second slider 52 from each other, but can deform according to the preset condition, so that the bonding process between the flexible screen 300 and the curved cover plate 200 is more controllable, and the bonding quality is higher. Since the bonding pad 53 has a flat supporting surface when the first slider 51 and the second slider 52 are in the closed state or the open state, the bonding pad 53 can better support the flexible screen 300 to be bonded to the curved cover plate 200 with high precision.
Wherein, laminating subassembly 5 still includes locking layering 520. The number of the locking beads 520 is two, and the two locking beads 520 are used to fix the first and second side portions 531 and 532, respectively. One of the locking beads 520 is located on the side of the first side 531 remote from the first slider 51. The other locking bead 520 is located on the side of the second side 532 remote from the second slide 52. In one embodiment, the locking bead 520 has a shape of a straight bar, and the locking bead 520 may extend in the third direction Y. In other embodiments, the locking bead 520 has a wavy strip shape, a pulse strip shape, or the like. The side of the locking bead 520 adjacent to the first side 531 toward the first side 531 is provided with a wavy surface to increase a contact area with the first side 531, thereby more firmly fixing the first side 531. The side of the locking bead 520 adjacent the second side 532 toward the second side 532 is provided with a wavy surface to increase the contact area with the second side 532, thereby more firmly securing the second side 532.
Conformable assembly 5 also includes a plurality of fasteners 530. The locking bead 520 is provided with a plurality of through holes. The plurality of fastening members 530 pass through the plurality of through holes in a one-to-one correspondence. A plurality of fasteners 530 also pass through the first or second side portions 531, 532, respectively, to secure the first side portion 531 to the first slider 51 and the second side portion 532 to the second slider 52 via the locking bead 520.
Wherein, laminating subassembly 5 still includes spacing layering 540. The number of the limiting pressing strips 540 is two. The locking bead 520 near the first side 531 is provided with a mounting groove 5201 at a side facing the first side 531. One of the limiting pressing bars 540 is installed in the mounting groove 5201 and abuts against the first side portion 531. The locking bead 520 near the second side 532 has a mounting groove 5201 on a side facing the second side 532. The other limit pressing bar 540 is installed in the installation slot 5201 and abuts against the second side 532. The depth direction of the mounting groove 5201 of the locking bead 520 is parallel to the first direction Z. At this time, the position limitation of the position limiting bead 540 to the first side 531 and the second side 532 can be adjusted by adjusting the position of the position limiting bead 540, for example, adjusting the depth of the position limiting bead 540 in the mounting groove 5201 of the locking bead 520, thereby adjusting the degree of tension of the attaching pad 53.
Referring to fig. 21, fig. 21 is a partial structural diagram of the structure shown in fig. 20. Fig. 21 includes a first slider 51, a second slider 52, and a bonding pad 53 shown in fig. 20.
The first side portion 531 is provided with a plurality of slot-shaped holes 5311 spaced apart from each other. The second side 532 is also provided with a plurality of slot-shaped apertures 5321 spaced apart from each other. The direction of extension of the slot-shaped holes (5311, 5321) is parallel to the first direction Z. The first slider 51 is provided with a plurality of fastening holes. The second slider 52 is also provided with a plurality of fastening holes. The plurality of fasteners 530 of the conformable assembly 5 pass through the plurality of slot-shaped apertures (5311, 5321) and the plurality of fastening apertures in a one-to-one correspondence.
At this time, since the position of the fastening member 530 in the slot holes (5311, 5321) can be adjusted along the first direction Z, the locking position of the first side portion 531 and the first slider 51 can be adjusted, the locking position of the second side portion 532 and the second slider 52 can be adjusted, the tension degree of the attaching pad 53 can be adjusted, and the attaching device 100 can better support the flexible screen 300 to attach to the curved cover plate 200 by adjusting the tension degree of the attaching pad 53.
In other embodiments, the first side 531 may not be fixed on the first side 513, but may be suspended or connected to the self-weight and suspended. The second side 532 may not be fixed on the second side 523 but may be suspended or connected to the self-weight and suspended. At this time, in the process of transforming the first and second sliders 51 and 52 from the closed state to the open state, one ends of the first and second side portions 531 and 533 move toward the first transition surface 512, and the other ends of the second and third side portions 532 and 533 move toward the second transition surface 522, so that the area of the region where the middle portion 533 of the attachment pad 53 contacts the first and second sliders 51 and 52 is larger, thereby supporting the attachment process of the flexible screen 300 to the curved cover 200.
Referring to fig. 16 again, optionally, when the first slider 51 and the second slider 52 are close to each other to a close state, the first supporting surface 511 and the second supporting surface 521 are spliced to form a continuous supporting surface 540. It will be appreciated that a gap between the first and second support surfaces 511, 521 is allowed due to manufacturing tolerances, assembly tolerances or assembly requirements.
At this time, the first slider 51 and the second slider 52 continuously support the attaching pad 53, thereby integrally supporting the middle region of the flexible screen 300 to be attached to the middle region of the curved cover plate 200, so that the attaching quality of the flexible screen 300 to the curved cover plate 200 is better.
Optionally, the bearing surface 540 is smoothly disposed. At this time, the supporting surface 540 supports the flexible screen 300 more smoothly, and the resistance of the bonding pad 53 moving relative to the supporting surface 540 is smaller and is not easily damaged.
In the present embodiment, the shape of conformable pad 53 is adapted to the shape of carrying surface 540. For example, when the attaching pad 53 completely attaches to the supporting surface 540, a region of a side surface of the attaching pad 53 away from the supporting surface 540, which is opposite to the supporting surface 540, is a planar region. At this moment, in the laminating process of flexible screen 300 and curved surface apron 200, laminating pad 53 is more steady to the support of flexible screen 300, and the laminating pressure of flexible screen 300 and curved surface apron 200 is even, can enough guarantee the laminating quality, also can reduce the risk that flexible screen 300 and curved surface apron 200 take place to damage in the laminating process.
The shape of the fit pad 53 and the shape of the carrying surface 540 have various embodiments:
in one embodiment, as shown in fig. 16, the carrying surface 540 includes a first planar area 5401, a recessed area 5402 and a second planar area 5403 sequentially arranged in the second direction X. The first planar area 5401 and the second planar area 5403 are parallel to the second direction X. The thickness of the portion of conformable pad 53 facing recessed area 5402 is greater than the thickness of the portion of conformable pad 53 facing first planar area 5401 and greater than the thickness of the portion of conformable pad 53 facing second planar area 5403. The portion of the fit pad 53 facing the bearing surface 540 is a portion of the middle portion 533. At this time, the middle portion 533 of the bonding pad 53 tends to be thick in the middle and thin on both sides. In the laminating process, the middle of the middle portion 533 of the laminating pad 53 can support the middle region of the flexible screen 300 slightly to be slightly raised, so that the laminating of the middle region of the curved cover plate 200 is firstly performed, the laminating sequence of the laminating of the middle part and the two sides is realized in the laminating process, and the laminating quality is improved.
Wherein the thickness of first side 531, second side 532, the thickness of the portion of conformable pad 53 opposite first planar region 5401 and the thickness of the portion opposite second planar region 5403 of central portion 533 of conformable pad 53 are uniform. The specific thickness and the specific shape of the pad 53 can be designed according to specific use requirements, which is not strictly limited in this application.
In the present embodiment, the shape of the bonding pad 53 may be variously configured:
in one version, as shown in fig. 16, the middle portion 533 of the conformable pad 53 includes a bottom surface facing the first slider 51 and the second slider 52 and a top surface facing away from the first slider 51 and the second slider 52. The bottom surface of the middle portion 533 includes a convex arc and two flat surfaces on either side of the arc. The top surface of the middle portion 533 is disposed symmetrically to the bottom surface of the middle portion 533. At this time, the reinforcing layer 534 (or the lubricating layer 535) disposed on the bottom surface of the middle portion 533 can play a fool-proof role, so that the attaching pad 53 is accurately assembled with the first slider 51 and the second slider 52.
In another embodiment, referring to fig. 22, fig. 22 is a schematic structural view of the pad 53 shown in fig. 16 in another embodiment. Most technical contents of the structure of the bonding pad 53 in this embodiment that are the same as the bonding pad 53 in the previous embodiment are not repeated. The bottom surface of the middle portion 533 of the attachment pad 53 is flat. In this case, the reinforcing layer 534 (or the lubricating layer 535) can be more easily fixed to the bottom surface of the middle portion 533, and the processing accuracy of the bonding pad 53 is higher. The top surface of middle portion 533 of conformable pad 53 includes a convex arc and two flat surfaces on either side of the arc.
In another embodiment, referring to fig. 23, fig. 23 is a schematic structural view of the pad 53 shown in fig. 16 in yet another embodiment. Most technical contents of the structure of the bonding pad 53 in this embodiment that are the same as the bonding pad 53 in the previous embodiment are not repeated. The bottom surface of the middle portion 533 of the conformable pad 53 includes a convex arc and two flat surfaces on either side of the arc.

The middle portion 533 of the fit pad 53 has a thickness equal to the thickness of the first side portion 531 and the thickness of the second side portion 532. In this case, the first slider 51, the second slider 52, and the bonding pad 53 are less difficult to process and are lower in cost. The reinforcing layer 534 (or the lubricating layer 535) on the bottom surface of the middle portion 533 of the attaching pad 53 can play a foolproof role. For example, first side 531 of conformable pad 53 may have a thickness in the range of 0.2 millimeters to 10 millimeters. For example, first side 531 of conformable pad 53 may have a thickness in the range of 0.5 millimeters to 6 millimeters.
It will be appreciated that in the previously described arrangement, the first slider 51 and the second slider 52 are symmetrically arranged. At this time, the same material may be used for the first slider 51 and the second slider 52, thereby reducing the cost of the laminating apparatus 100. In other embodiments, the first slider 51 and the second slider 52 may not be symmetrically disposed. For example:

The part of the attaching assembly 5 for supporting the flexible screen 300 and the part of the mounting assembly 3 for mounting the curved cover plate 200 move relatively, that is, the attaching assembly 5 and the mounting assembly 3 move relatively in the first direction Z.
Referring to fig. 33, fig. 33 is a schematic partial structure view of the bonding apparatus 100 shown in fig. 31. Fig. 33 mainly includes the structure of the pasting member 5 of the pasting apparatus 100.
The attaching assembly 5 includes a first slider 51, a second slider 52, a supporting block 550 and an attaching pad 53. The first slider 51 and the second slider 52 are aligned in the second direction X, and can approach and move away from each other. The second direction X is perpendicular to the first direction Z. The supporting block 550 is located between the first slider 51 and the second slider 52. That is, the first slider 51, the support block 550, and the second slider 52 are sequentially arranged in the second direction X. The first slider 51 and the second slider 52 can approach and separate from the supporting block 550. The pad 53 is made of an elastic material. Conformable pad 53 may deform when subjected to a force. The fit pad 53 is located on the side of the first slider 51 and the second slider 52 facing the mount assembly 3. The fit pad 53 extends from a side of the first slider 51 away from the second slider 52 to a side of the second slider 52 away from the first slider 51. The attaching pad 53 is used for supporting the flexible screen 300 to be stacked and attached to the curved cover plate 200 along the first direction Z.
In this embodiment, the attaching assembly 5 may attach the middle region of the flexible screen 300 and the middle region of the curved cover plate 200 through the attaching pad 53 when the first slider 51 and the second slider 52 are close to the supporting block 550 to the closed state, and attach the edge region of the flexible screen 300 and the edge region of the curved cover plate 200 through the attaching pad 53 when the first slider 51 and the second slider 52 are far from the supporting block 550 to the open state, so that the flexible screen 300 and the curved cover plate 200 are attached in stages, and the attaching sequence is first between the middle and the two sides, thereby reducing risks of occurrence of bubbles, cracks, wrinkles and other defects, so that the attaching quality of the curved cover plate 200 and the flexible screen 300 is better, and the product yield of the screen formed after the curved cover plate 200 and the flexible screen 300 are attached is higher.
Because laminating subassembly 5 supports flexible screen 300 through laminating pad 53, laminating pad 53 adopts elastic material, not only can transmit first slider 51, the holding power of second slider 52 and supporting shoe 550 for flexible screen 300 and curved surface capping through laminating pad 53, make flexible screen 300 laminate with the curved surface capping, laminating pad 53's cushioning effect and indirect supporting effect make flexible screen 300 can keep stable position and state in the laminating in-process moreover, make the laminating quality of flexible screen 300 and curved surface capping 200 better.
In addition, when the first slider 51 and the second slider 52 are far away from the supporting block 550 to the open state, the supporting block 550 can still support the flexible screen 300 through the attaching pad 53, so that the attaching process of the flexible screen 300 and the curved cover plate 200 is more stable, the flexible screen 300 and the curved cover plate 200 are not easy to deform, and the attaching quality is better.

In this embodiment, since the first slider 51 is driven by the first slider driving member 551 and the second slider 52 is driven by the second slider driving member 552, the first slider 51 and the second slider 52 can be operated independently of each other, for example, the first slider 51 and the second slider 52 can be moved simultaneously, sequentially, or one can be moved while the other is not moved. Therefore, the movement of the first slider 51 and the second slider 52 is more flexible, and the step of attaching the flexible screen 300 and the curved cover 200 of the attaching apparatus 100 is more flexible and diversified.
The first slider driving member 551 and the second slider driving member 552 may employ servo motors. The servo motor adopts a closed-loop feedback system and has accurate position precision, so that the positions and the moving speeds of the first slider 51 and the second slider 52 can be accurately controlled, the position precision of the first slider 51 and the second slider 52 is high, and the reliability of the laminating process of the laminating device 100 is ensured. For example, the conforming process can be accomplished by a loop of positions of the first slider drive 551 and the second slider drive 552. The design parameters of the first slider drive 551 and the design parameters of the second slider drive 552 may be the same or different.
Moreover, a feedback system of the servo motor can also respond in time, and the first slider 51 and the second slider 52 push the flexible screen 300 to be attached to the curved cover plate 200, so that the attaching pressure between the flexible screen 300 and the curved cover plate 200 is adjusted in time, and the attaching precision of the attaching device 100 is higher. In other embodiments, the first slider drive 551 and the second slider drive 552 may be implemented by conventional motors or pneumatic cylinders. In addition, the first slider driving member 551 and the second slider driving member 552 can also be set to the initial positions by the servo motor, so that the first slider 51 and the second slider 52 can accurately move back to the initial positions when approaching to the close state, thereby ensuring the attaching precision in the next attaching process.
It is understood that the design of the position of the laminating platform 54 of the laminating assembly 5 of the laminating apparatus 100 shown in this embodiment can also be implemented in various ways, for example, it can be a fixed platform or a movable platform, as described in the first embodiment.
It is understood that the structural design of the laminating platform 54 of the laminating assembly 5 of the laminating apparatus 100 shown in this embodiment can also be implemented in various ways, for example, it can be a platform with two relatively fixed sides, or a platform with two relatively movable sides, as described in the first embodiment.
Optionally, with continued reference to fig. 33, conformable assembly 5 further includes a first pressure sensor 5501 and a second pressure sensor 5502. The first pressure sensor 5501 is disposed between the support block 550 and the first slider 51. The first pressure sensor 5501 serves to detect the pressure between the support block 550 and the first slider 51. The second pressure sensor 5502 is disposed between the support block 550 and the second slider 52. The second pressure sensor 5502 detects the pressure between the support block 550 and the second slider 52.
In this embodiment, the bonding assembly 5 may obtain the pressure between the supporting block 550 and the second slider 52 and the pressure between the supporting block 550 and the second slider 52 through the first pressure sensor 5501 and the second pressure sensor 5502, so as to feed back the bonding pressure when the edge region of the flexible screen 300 supported by the first slider 51 and the second slider 52 is bonded to the edge region of the curved cover plate 200, and further diagnose whether the bonding process is qualified through the bonding pressure, and also adjust the parameters (for example, parameters of the driving assembly) of the bonding device 100 in time through the bonding pressure, thereby optimizing the bonding process between the curved cover plate 200 and the flexible screen 300 in time, and improving the bonding quality.
Referring to fig. 34 to 36 together, fig. 34 is a partial structural schematic view of the attaching assembly 5 shown in fig. 33, fig. 35 is an exploded view of the structure shown in fig. 34, and fig. 36 is a structural schematic view of the structure shown in fig. 34 in another use state. Fig. 34 illustrates the first slider 51, the second slider 52, the supporting block 550 and the attaching pad 53 of the attaching assembly 5.
The first slider 51 includes a first supporting surface 511, a first transition surface 512 and a first side surface 513 connected in sequence. The second slider 52 includes a second supporting surface 521, a second transition surface 522 and a second side surface 523, which are sequentially connected. The first support surface 511 and the second support surface 521 are disposed facing the mounting assembly 3, and the first side surface 513 and the second side surface 523 are disposed opposite to each other and both are recessed toward each other. Conformable pad 53 contacts first transition surface 512, first support surface 511, second support surface 521 and second transition surface 522.
In this embodiment, since the first side surface 513 and the second side surface 523 are recessed toward each other, that is, the first side surface 513 and the second side surface 523 are waisted, a portion corresponding to the first transition surface 512 forms a vertex angle with a smooth surface, and a portion corresponding to the second transition surface 522 forms a vertex angle with a smooth surface. In the process that the first slider 51 and the second slider 52 are away from each other to the open state, the vertex angle formed by the first slider 51 and the second slider 52 can be abutted against the flexible screen 300 through the attaching pad 53 and the carrier film 400, so that the edge area of the flexible screen 300 is attached to the edge area of the curved cover plate 200. Moreover, the vertex angles of the first slider 51 and the second slider 52 can be adapted to the bending angle of the edge area of the curved cover plate 200, so that the attaching device 100 can be better applied to the attaching environment of the curved cover plate 200 with a large bending angle. In addition, the third supporting surface can continuously support the flexible screen 300 in the attaching process, so that the attaching process of the flexible screen 300 and the curved cover plate 200 is more stable, and the attaching quality is better.
The support block 550 includes a third support surface 5503 facing the mounting assembly 3. The conformable pad 53 may also be capable of contacting the third support surface 5503. When the first slider 51 and the second slider 52 approach the supporting block 550 to the closed state, the first supporting surface 511, the third supporting surface 5503 and the second supporting surface 521 are spliced into a continuous supporting surface 540. At this time, the bearing surface 540 can continuously support the flexible screen 300, so that the attachment quality of the middle region of the flexible screen 300 and the middle region of the curved cover plate 200 is higher. Optionally, the bearing surface 540 is smoothly disposed. At this time, the supporting surface 540 supports the flexible screen 300 more smoothly, and the resistance of the bonding pad 53 moving relative to the supporting surface 540 is smaller and is not easily damaged.
As shown in fig. 34, when the first slider 51 and the second slider 52 approach the supporting block 550 to the closed state, the first supporting surface 511 forms a supporting region of the first slider 51, the third supporting surface 5503 forms a supporting region of the supporting block 550, the second supporting surface 521 forms a supporting region of the second slider 52, and the first supporting surface 511, the third supporting surface 5503 and the second supporting surface 521 support the attaching pad 53 together, so that the middle region of the flexible screen 300 supported by the attaching pad 53 is attached to the middle region of the curved cover plate 200. As shown in fig. 36, when the first slider 51 and the second slider 52 are moved away from each other to an open state, the first supporting surface 511 and the first transition surface 512 together form a supporting region of the first slider 51, the second supporting surface 521 and the second transition surface 522 together form a supporting region of the second slider 52, and the first supporting surface 511, the first transition surface 512, the second supporting surface 521 and the second transition surface 522 together support the attaching pad 53, so that the edge region of the flexible screen 300 is supported by the attaching pad 53 to be attached to the edge region of the curved cover plate 200. At this time, the third supporting surface 5503 forms a supporting region of the supporting block 550, and the third supporting surface 5503 still supports the attaching pad 53, so that the middle region of the flexible screen 300 maintains an attaching state with the central region of the curved cover plate 200.
Referring to fig. 34 to fig. 36 again, the pad 53 includes a first side portion 531, a second side portion 532, and a middle portion 533 between the first side portion 531 and the second side portion 532. When the first slider 51 and the second slider 52 move away from the supporting block 550 to the open state, the first side portion 531 faces the first side surface 513, the second side portion 532 faces the second side surface 523, and the middle portion 533 faces the first transition surface 512, the first supporting surface 511, the second supporting surface 521, the second transition surface 522, and the third supporting surface 5503.
In this embodiment, middle portion 533 of conformable pad 53 can be used to support carrier film 400 and flexible screen 300. Because the first side portion 531 faces the first side surface 513 and the second side portion 532 faces the second side surface 523 when the first slider 51 and the second slider 52 are far away from the supporting block 550 to the open state, the middle portion 533 can keep the state of covering the supporting areas of the first slider 51, the second slider 52 and the supporting block 550 in the attaching process, so that the flexible screen 300 can be stably supported, and the attaching quality of the flexible screen 300 and the curved cover plate 200 is better.
Wherein, a first sliding slot 518 is disposed on one side of the first sliding block 51 facing the supporting block 550. The second slide block 52 is provided with a second sliding groove 528 at a side facing the supporting block 550. The support block 550 includes a first sliding protrusion 5504 and a second sliding protrusion 5505 disposed back to back. The first sliding protrusion 5504 is slidably mounted to the first sliding groove 518. The second sliding protrusion 5505 is slidably mounted to the second sliding groove 528. Wherein, one side surfaces of the first sliding protrusion 5504 and the second sliding protrusion 5505 may form a portion of the third support surface 5503 to increase an area of the third support surface 5503, so that the support area of the support block 550 to the fitting pad 53 is larger.
It is understood that other designs (such as structural design, position design, material design, etc.) of the fit pad 53, the first slider 51, the support block 550 and the second slider 52 can refer to the first embodiment, and are not described herein. Without conflict, conformable assembly 5 of the present embodiment may be combined with the features of conformable assembly 5 of the first embodiment.
Alternatively, the shape of the side surface of the supporting block 550 facing the first slider 51 and the shape of the side surface facing the second slider 52 may be designed in various ways, for example, they may be designed as a vertical surface, an inclined surface, a curved surface, etc., and this is not limited in this application. The shape of the side surface of the support block 550 facing the first slider 51 and the shape of the side surface facing the second slider 52 are designed so that the support block 550 is completely engaged with the first slider 51 and the second slider 52 as much as possible.
Referring to fig. 37 and 38 together, fig. 37 is a schematic view of an internal structure of a pasting apparatus 100 according to an embodiment of the present application in a third embodiment, and fig. 38 is a schematic view of the pasting apparatus 100 shown in fig. 37 in a use state. Hatching in each structure is omitted in each of fig. 37 and 38, so that the structure of each component of the laminating apparatus 100 is clearly illustrated. In the following drawings of the embodiments of the present application, the contents of the drawings are the partial structure or related structure of the laminating apparatus 100 shown in fig. 37, and the hatching in the structure is also omitted, and the description is incorporated herein.
Most technical contents of the attaching device 100 shown in the third embodiment are the same as those of the attaching device 100 shown in the first embodiment, and are not described in detail later. Hereinafter, differences of the third embodiment from the first embodiment and a part of technical contents in the third embodiment will be mainly described, and the same contents as those in the first embodiment may exist in this part.
The attaching device 100 includes a fixing frame 1, a cavity assembly 2, a mounting assembly 3, a clamping assembly 4 and an attaching assembly 5. The attaching device 100 is used for laminating and attaching the curved cover plate 200 and the flexible screen 300 together along the first direction Z. In the present embodiment, the first direction Z is taken as an example of a vertical direction, that is, the movement along the first direction Z is an up-down movement.
Mount 1 is used to mount and support other component parts of laminating apparatus 100. The chamber body assembly 2 includes a first chamber body 21 and a second chamber body 22. The first cavity 21 and the second cavity 22 can be close to and far from each other in the first direction Z. The mounting component 3 is movably mounted on the fixed frame 1. The mounting assembly 3 is used to mount the curved cover plate 200. The clamping component 4 is movably arranged on the fixed frame 1. The clamping assembly 4 is located below the mounting assembly 3. The clamping assembly 4 is used for clamping two ends of the carrier film 400 carrying the flexible screen 300, and the carrier film 400 is located between the mounting assembly 3 and the attaching assembly 5. The flexible screen 300 is located on the side of the carrier film 400 facing the cover plate. In this embodiment, the structure of the fixing frame 1, the structure of the cavity assembly 2, the structure of the mounting assembly 3, and the structure of the clamping assembly 4 can be referred to the related description of the first embodiment.
The attaching component 5 is movably arranged on the fixed frame 1. The attaching member 5 is located below the mounting member 3. The attaching member 5 and the mounting member 3 are relatively movable in the first direction Z. The attaching assembly 5 is used for supporting the flexible screen 300 to be stacked and attached to the curved cover plate 200 along the first direction Z. The part of the attaching assembly 5 for supporting the flexible screen 300 and the part of the mounting assembly 3 for mounting the curved cover plate 200 move relatively, that is, the attaching assembly 5 and the mounting assembly 3 move relatively in the first direction Z.
Referring to fig. 39, fig. 39 is a partial structural schematic view of the attaching device 100 shown in fig. 37. Fig. 39 mainly includes the structure of the pasting member 5 of the pasting apparatus 100.
The attaching assembly 5 includes an attaching platform 54, a first slider 51, a second slider 52, a pressing block 580 and an attaching pad 53. The first slider 51 and the second slider 52 are aligned in the second direction X, and can approach and move away from each other. The second direction X is perpendicular to the first direction Z. The first slider 51 and the second slider 52 are slidably mounted on the attaching platform 54. The pressing block 580 is mounted to the applying platform 54 and is movable in the first direction Z with respect to the applying platform 54. The pressing block 580 is located between the first slider 51 and the second slider 52. The pressing block 580 includes a first sliding surface 5801 and a second sliding surface 5802 spaced apart from each other. The first sliding surface 5801 and the second sliding surface 5802 are away from each other in a direction away from the fitting stage 54. The first slider 51 contacts the first sliding surface 5801. The second slider 52 contacts the second sliding surface 5802. Wherein the pressing block 580 may have a substantially inverted trapezoidal shape.
The pad 53 is made of an elastic material. Conformable pad 53 may deform when subjected to a force. The fit pad 53 is located on the side of the first slider 51 and the second slider 52 facing the mount assembly 3. The abutment pad 53 is also located on the side of the crush block 580 facing the mounting assembly 3. The fit pad 53 extends from a side of the first slider 51 away from the second slider 52 to a side of the second slider 52 away from the first slider 51. The attaching pad 53 is used for supporting the flexible screen 300 to be stacked and attached to the curved cover plate 200 along the first direction Z.
In this embodiment, when the pressing block 580 is in the ejected state, the pressing block 580 protrudes in a direction away from the attaching platform 54 relative to the first slider 51 and the second slider 52, the first slider 51 and the second slider 52 are in the closed state, and the distance between the first slider 51 and the second slider 52 is small. When the pressing block 580 is forced to move to a pressing state in a direction close to the attaching platform 54, the first slider 51 and the second slider 52 are pushed away towards two sides by the pressing block 580, the first slider 51 and the second slider 52 are in an opening state, and the distance between the first slider 51 and the second slider 52 is larger.
The attaching assembly 5 can attach the middle region of the flexible screen 300 and the middle region of the curved cover plate 200 through the supporting of the extrusion block 580 and the attaching pad 53 when the extrusion block 580 is in the ejection state and the first slider 51 and the second slider 52 are in the closing state, further support the edge region of the flexible screen 300 and attach the edge region of the curved cover plate 200 through the first slider 51, the second slider 52 and the attaching pad 53 when the extrusion block 580 is in the pressing state and the first slider 51 and the second slider 52 are in the opening state, so that the flexible screen 300 and the curved cover plate 200 are attached in stages, the attaching sequence is firstly from the middle to the back, risks of bubbles, cracks, wrinkles and the like are reduced, the attaching quality of the curved cover plate 200 and the flexible screen 300 is better, and the product yield of the screen formed after the curved cover plate 200 and the flexible screen 300 are attached is higher.
Because laminating subassembly 5 supports flexible screen 300 through laminating pad 53, laminating pad 53 adopts elastic material, not only can transmit first slider 51, the holding power of second slider 52 and supporting shoe 550 for flexible screen 300 and curved surface capping through laminating pad 53, make flexible screen 300 laminate with the curved surface capping, laminating pad 53's cushioning effect and indirect supporting effect make flexible screen 300 can keep stable position and state in the laminating in-process moreover, make the laminating quality of flexible screen 300 and curved surface capping 200 better.
In addition, in the process that the pressing block 580 moves from the ejection state to the press-in state, the middle region of the flexible screen 300 can be continuously supported, so that the middle region of the flexible screen 300 and the middle region of the curved cover plate 200 are kept in a bonding state, and the bonding quality of the two is ensured.
In this embodiment, since the movement of the first slider 51 and the second slider 52 is pushed by the pressing block 580, the attaching assembly 5 does not need to be additionally provided with a driving assembly, thereby reducing the cost of the attaching apparatus 100 and simplifying the attaching process step of the attaching apparatus 100.
The first slider 51, the second slider 52 and the attaching platform 54 may be directly connected or indirectly connected. The present embodiment is described by taking a direct connection as an example. Referring to fig. 37 and 39, the first slider 51, the second slider 52, the pressing block 580 and the bonding platform 54 are located inside the second cavity 22. Conformable assembly 5 further includes a platform support 590. Platform support 590 is mostly located the second cavity 22 outside, and platform support 590 is a little stretched into the second cavity 22 inboard to support laminating platform 54, it is specific:
A sliding rail structure is formed between the first sliding block 51 and the attaching platform 54, and the extending direction of the sliding rail structure is parallel to the second direction X. The second slider 52 and the attaching platform 54 form a slide rail structure therebetween, and the extending direction of the slide rail structure is parallel to the second direction X. At this time, the attaching platform 54 can define the moving direction of the first slider 51 and the second slider 52, thereby ensuring the operational reliability of the attaching assembly 5.
The platform support 590 includes a driving portion 5901 and a supporting portion 5902. Drive portion 5901 is positioned outside of second cavity 22 and support portion 5902 is supported between drive portion 5901 and conformable platform 54. The second cavity 22 has one or more ninth through holes 228. The number of the support portions 5902 is one or more. The one or more supporting portions 5902 extend from the one or more ninth through holes 228 into the inside of the second cavity 22 in a one-to-one correspondence. Conformable assembly 5 further includes one or more ninth vacuum bellows 5903. One or more ninth vacuum bellows 5903 are sleeved between the one or more support portions 5902 in a one-to-one correspondence.
Optionally, with continued reference to FIG. 39, the laminating assembly 5 further includes a laminating platform drive assembly 510. Conformable station drive assembly 510 is used to drive conformable station 54 in a first direction Z. In this embodiment, the bonding platform driving assembly 510 is connected to the platform supporting member 590, and drives the platform supporting member 590 to move, so as to drive the bonding platform 54 to move. The specific design of the platen driving assembly 510 in this embodiment can be referred to as the first embodiment.
In other embodiments, the attaching platform 54 may also be located outside the second cavity 22 and connected to the first slider 51, the second slider 52 and the pressing block 580 through a connecting member or a transmission member. In this embodiment, the bonding stage driving assembly 510 can directly drive the bonding stage 54 to move.
In other embodiments, the attachment platform 54 may be a fixed platform. Specific design reference may be made to the first embodiment.
It is understood that the structural design of the laminating platform 54 of the laminating assembly 5 of the laminating apparatus 100 shown in this embodiment can be implemented in various ways, for example, it can be a platform with two relatively fixed sides, or a platform with two relatively movable sides, as described in the first embodiment. For example, the attachment platform 54 includes an upper platform, a lower platform, and a resilient member. The first sliding block, the extrusion block and the second sliding block are arranged on the upper platform. The lower platform is positioned on one side of the upper platform far away from the extrusion block. The elastic piece is connected between the lower platform and the upper platform so that the upper platform and the lower platform can move relatively.
Optionally, as shown in fig. 39, conformable assembly 5 further includes a fourth pressure sensor 5904. The fourth pressure sensor 5904 is provided between the first slider 51 and the second slider 52. The fourth pressure sensor 5904 is used to detect the pressure between the first slider 51 and the second slider 52. At this moment, the fourth pressure sensor 5904 can acquire the pressure between the first slider 51 and the second slider 52, thereby feedback out the laminating pressure when the edge region that the first slider 51 and the second slider 52 supported the flexible screen 300 and the edge region of curved surface apron 200 laminate mutually, and then whether qualified through the laminating pressure diagnosis laminating process, still can in time adjust the parameter of laminating equipment 100 through laminating pressure, thereby in time optimize the laminating process of curved surface apron 200 and flexible screen 300, improve the laminating quality.
With continued reference to FIG. 39, optionally, conformable assembly 5 may further include a resilient support 5905. Resilient support 5905 is located between the expression block 580 and the conformable platform 54. When the pressing block 580 is forced close to the fitting platform 54, the elastic support 5905 is compressed, and the first slider 51 and the second slider 52 move away from each other. In other words, during the process of transforming the pressing block 580 from the ejected state to the pressed state, the elastic support 5905 is gradually compressed, thereby generating an elastic force supporting the pressing block 580, so that the pressing block 580 can support the flexible screen 300 through the fit pad 53.
In one embodiment, the resilient support 5905 is a spring or other resilient member.
In another embodiment, the elastic support 5905 includes a guide for limiting the movement of the pressing block 580 along the first direction Z and an elastic member sleeved on the guide, which may be a spring or other structure.
With continued reference to FIG. 39, the attachment assembly 5 may optionally further include a resilient tensioning member 5906. The elastic tension member 5906 is located between the first slider 51 and the second slider 52. The elastic tension member 5906 is in a stretched state, so as to generate an elastic force between the first slider 51 and the second slider 52 to make them approach each other, so as to ensure the normal operation of the fitting assembly 5. The elastic tension member 5906 may be a spring or other elastic member.
When the pressing block 580 is in the ejection state, the elastic support 5905 may be in a stretched state, so as to generate a force that causes the pressing block 580 to approach the attaching platform 54, and the elastic force of the elastic support 5905 and the elastic force of the elastic tensioning member 5906 balance the pressing block 580, the first slider 51, and the second slider 52, thereby preventing the pressing block 580 from departing from a predetermined position, and enhancing the reliability of the attaching assembly 5.
Referring to fig. 40 to 42 together, fig. 40 is a partial structural schematic view of the attaching assembly 5 shown in fig. 37, fig. 41 is an exploded view of the structure shown in fig. 40, and fig. 42 is a structural schematic view of the structure shown in fig. 40 in another use state. Fig. 40 illustrates the structure of the first slider 51, the second slider 52, the pressing block 580, the bonding pad 53 and the bonding platform 54 of the bonding assembly 5.
The first slider 51 includes a first supporting surface 511, a first transition surface 512 and a first side surface 513 connected in sequence. The second slider 52 includes a second supporting surface 521, a second transition surface 522 and a second side surface 523, which are sequentially connected. The first and second support surfaces 511 and 521 are each disposed facing the mounting component 3. The first side surface 513 and the second side surface 523 are disposed opposite to each other and both are recessed toward each other. Conformable pad 53 may contact first transition surface 512, first support surface 511, second support surface 521, and second transition surface 522. Conformable pad 53 may also contact a top surface 5803 of crush block 580 facing away from conformable platform 54. The top surface 5803 of the crush block 580 faces the mounting assembly 3.
In this embodiment, since the first side surface 513 and the second side surface 523 are recessed toward each other, that is, the first side surface 513 and the second side surface 523 are waisted, a portion corresponding to the first transition surface 512 forms a vertex angle with a smooth surface, and a portion corresponding to the second transition surface 522 forms a vertex angle with a smooth surface. In the process that the first slider 51 and the second slider 52 are away from each other to the open state, the vertex angle formed by the first slider 51 and the second slider 52 can be abutted against the flexible screen 300 through the attaching pad 53 and the carrier film 400, so that the edge area of the flexible screen 300 is attached to the edge area of the curved cover plate 200. Moreover, the vertex angles of the first slider 51 and the second slider 52 can be adapted to the bending angle of the edge area of the curved cover plate 200, so that the attaching device 100 can be better applied to the attaching environment of the curved cover plate 200 with a large bending angle. In addition, the top surface 5803 of the extrusion block 53 can continuously support the flexible screen 300 in the attaching process, so that the attaching process of the flexible screen 300 and the curved cover plate 200 is more stable, and the attaching quality is better.
In one embodiment, when the pressing block 580 is in the ejection state and the first slider 51 and the second slider 52 are in the closing state, the fit pad 53 contacts the top surface 5803, the first transition surface 512, the first supporting surface 511, the second supporting surface 521 and the second transition surface 522 of the pressing block 580; in another embodiment, as shown in fig. 41, when the pressing block 580 is in the ejected state and the first slider 51 and the second slider 52 are in the closed state, the fit pad 53 contacts the top surface 5803, the first transition surface 512 and the second transition surface 522 of the pressing block 580. At this time, since the height of the pressing block 580 protruding with respect to the first slider 51 and the second slider 52 is large, the contact between the attaching pad 53 and the first supporting surface 511 and the second supporting surface 521 is temporarily kept.
Optionally, as shown in fig. 42, when the first slider 51 and the second slider 52 are away from each other to an open state, the first supporting surface 511 and the pressing block 580 are far away from the top surface 5803 of the attaching platform 54 and the second supporting surface 521 to be spliced into a continuous supporting surface 540. At this time, the bearing surface 540 can continuously support the flexible screen 300, so that the quality of the attachment of the flexible screen 300 to the curved cover plate 200 is higher. Wherein the carrying surface 540 is smoothly disposed. At this time, the supporting surface 540 supports the flexible screen 300 more smoothly, and the resistance of the bonding pad 53 moving relative to the supporting surface 540 is smaller and is not easily damaged.
Referring to fig. 40 to 42, the pad 53 includes a first side portion 531, a second side portion 532, and a middle portion 533 between the first side portion 531 and the second side portion 532. When the first slider 51 and the second slider 52 move away from each other to the open state, the first side portion 531 faces the first side surface 513, the second side portion 532 faces the second side surface 523, and the middle portion 533 faces the first transition surface 512, the first supporting surface 511, the second supporting surface 521, the second transition surface 522, and the top surface 5803 of the pressing block 580.
In this embodiment, middle portion 533 of conformable pad 53 can be used to support carrier film 400 and flexible screen 300. Since the first side portion 531 faces the first side surface 513 and the second side portion 532 faces the second side surface 523 when the first slider 51 and the second slider 52 are pressed to the open state by the pressing block 580, the middle portion 533 can maintain a state of covering a supporting area (an area for supporting the attaching pad 53) of the first slider 51, the second slider 52 and the pressing block 580 during attaching, so that the flexible screen 300 can be stably supported, and the attaching quality of the flexible screen 300 and the curved cover plate 200 is better.
Wherein, a first limit groove 519 is provided at one side of the first slider 51 facing the extrusion block 580. A second limiting groove 529 is formed on one side of the second sliding block 52 facing the pressing block 580. The expression nub 580 includes a first retention bump 5804 and a second retention bump 5805 that are disposed back-to-back. When the extrusion block 580 is in a pressed-in state, the first limiting protrusion 5804 is positioned in the first limiting groove 519 and abuts against the wall surface of the first limiting groove 519; the second limiting protrusion 5805 is located in the second limiting groove 529 and abuts against a wall surface of the second limiting groove 529. At this time, the pressing block 580 maintains a stable position with respect to the first slider 51 and the second slider 52, thereby maintaining the flexible screen 300 in a stable attached state with the curved cover 200. When the pressing block 580 is in the ejected state, the first limiting protrusion 5804 leaves the wall surface of the first limiting groove 519, and the second limiting protrusion 5805 leaves the wall surface of the second limiting groove 529. Wherein, one side surface of the first and second limit protrusions 5804 and 5805 may form a portion of the top surface 5803 of the pressing block 580 to increase the area of the top surface 5803 of the pressing block 580, so that the pressing block 580 has a larger supporting area for the attaching pad 53.
It is understood that other designs (such as structural design, position design, material design, etc.) of the fit pad 53, the first slider 51, the pressing block 580 and the second slider 52 can refer to the first embodiment, and are not described herein. Without conflict, conformable assembly 5 of the present embodiment may be combined with the features of conformable assembly 5 of the first embodiment.
The embodiment of the application further provides a fitting device, which is used for stacking and fitting the curved cover plate and the flexible screen together along the first direction. The laminating device comprises a mounting assembly, a clamping assembly and the laminating assembly described in the previous embodiment. The mounting assembly is used for mounting the curved cover plate. The attaching assembly and the mounting assembly can move relatively in a first direction, and the first direction is perpendicular to a second direction.

The attaching method can be applied to the attaching device in the embodiment, and can also be applied to other attaching devices capable of realizing the attaching method.

For example, the curved cover plate may be a protective cover plate with an arc-shaped edge applied to various electronic devices, the attachment surface on the inner side of the protective cover plate is curved, and the protective cover plate may be a front cover plate or a rear cover plate of the electronic device. In an alternative embodiment, the central region of the curved cover plate is a planar portion. The edge region of the curved cover plate includes a curved portion at the end.

Referring to fig. 43, fig. 43 is a flowchart illustrating a bonding method according to a first embodiment of the present application. Fig. 43 illustrates the main steps of the attaching method, and the attaching method may further include steps not illustrated in fig. 43.

The respective steps of the bonding method will be described below with reference to schematic structural diagrams in the specific steps. The following bonding method is described by taking as an example the case where it is performed in the bonding apparatus shown in the foregoing embodiment.
In one embodiment, please refer to fig. 44, wherein fig. 44 is a first structural diagram corresponding to the bonding method shown in fig. 43.
The attaching apparatus 100 includes a mounting assembly 3, an attaching assembly 5, and a clamping assembly 4. The mounting assembly 3 includes a mounting base 31 for mounting the curved cover plate 200. The attachment member 5 and the mounting member 3 are arranged substantially along the first direction Z. The attaching member 5 is located below the mounting member 3. The clamping assembly 4 comprises a first clamping jaw 41 and a second clamping jaw 42. The first clamping claw 41 and the second clamping claw 42 are respectively positioned at two sides of the attaching assembly 5.
The attaching assembly 5 includes a first slider 51, a second slider 52 and an attaching pad 53. The first slider 51 and the second slider 52 are aligned in the second direction X, and can approach and move away from each other. The first slider 51 and the second slider 52 may be close to each other in the second direction X to a closed state, or may be away from each other in the second direction X to an open state. The second direction X is perpendicular to the first direction Z. The pad 53 is made of an elastic material. Conformable pad 53 may deform when subjected to a force. The fit pad 53 is located on the side of the first slider 51 and the second slider 52 facing the mount assembly 3. The fit pad 53 extends from a side of the first slider 51 away from the second slider 52 to a side of the second slider 52 away from the first slider 51.
Before the step 010, the attaching method further includes an apparatus aligning step. The equipment alignment step comprises:
step 001: the mounting base 31 and the bonding pad 53 are aligned at the center. Specifically, the center of the bottom wall of the mounting station 311 of the mounting base 31 is aligned with the center of the fit pad 53 in the first direction Z. Further, the bottom wall of the mounting station 311 of the mounting base 31 may be substantially parallel to the portion of the bonding pad 53 located above the first slider 51 and the second slider 52.
In one embodiment, one or both of mounting base 31 and conformable pad 53 may be movable in second direction X. Further, one or both of mounting base 31 and conformable pad 53 may be movable in third direction Y. The third direction Y is perpendicular to the second direction X.
Step 002: the first gripper jaw 41 and the second gripper jaw 42 are moved so that the heights of the first gripper jaw 41 and the second gripper jaw 42 in the first direction Z coincide. At this time, the plane of the clamping area of first clamping claw 41 and second clamping claw 42 is approximately parallel to bonding pad 53.
In one embodiment, the first gripper jaw 41 and the second gripper jaw 42 are movable in the first direction Z.
Step 003: the first gripper claw 41 and the second gripper claw 42 are moved so that the first gripper claw 41 and the second gripper claw 42 are equally spaced from the application pad 53 in the second direction X. Wherein, the step 003 can be carried out separately from the step 002, and the order of the two can be exchanged. Step 003 may also be performed simultaneously with step 002.
In one embodiment, the first gripper jaw 41 and the second gripper jaw 42 are movable in the second direction X.
In another embodiment, if the first gripper jaw 41 and the second gripper jaw 42 have no degree of freedom in the first direction Z, the first gripper jaw 41 and the second gripper jaw 42 are mechanically positioned so that the heights thereof in the first direction Z are the same between the steps 001. If there is no degree of freedom in the second direction X in the first and second clamping jaws 41 and 42, the distance between the first and second clamping jaws 41 and 42 and the bonding pad 53 in the second direction X is made equal by synchronously moving the mounting base 31 and the bonding module 5.
In this embodiment, in the attaching method, through the device alignment step, the core component in the attaching device 100 is moved to a suitable position in advance, so that the subsequent steps can be performed smoothly, the debugging time of the subsequent steps is reduced, and the attaching precision of the curved surface cover plate 200 and the flexible screen 300 can be increased.
It is understood that the equipment alignment step is an optional step of the lamination method, and is not a necessary step.
Referring to fig. 45, fig. 45 is a second structural schematic diagram corresponding to the bonding method shown in fig. 43. Fig. 45 corresponds to step 010 and step 020 of the bonding method.
Step 010: the curved cover plate 200 is fixed to the mounting assembly 3. The curved cover plate 200 includes a middle region and edge regions at both sides of the middle region.
Wherein "fixing the curved surface cover plate 200 to the mounting member 3" includes:
the curved surface cover plate 200 is preliminarily fixed in the mounting station 311 of the mounting base 31 of the mounting assembly 3 by vacuum suction.
The first clamping block 37 and the second clamping block 38 are moved relative to each other (see fig. 8) to secure the curved cover plate 200. The first clamping block 37 and the second clamping block 38 can be moved in the manner described with reference to the previous embodiments.
In this embodiment, since the curved cover plate 200 is further clamped and fixed by the first clamping block 37 and the second clamping block 38, the curved cover plate 200 can still be kept still after the vacuum suction action on the curved cover plate 200 fails in the vacuum environment in the subsequent step, thereby ensuring the attaching effect of the curved cover plate 200 and the flexible screen 300.
In the drawings of the first embodiment, the curved cover 200 is illustrated as having a large bending angle in the edge area. For example, the middle region of the curved cover plate 200 is a flat region, the edge region of the curved cover plate 200 is a curved region, and the bending angle is greater than or equal to 60 °.
Step 020: the chucking assembly 4 chucks both ends of the carrier film 400. The carrier film 400 includes a first surface 4001 facing the curved cover plate 200 and a second surface 4002 facing away from the curved cover plate 200. The first face 4001 carries a flexible screen 300 thereon.
Wherein, the "holding assembly 4 holds both ends of the carrier film 400" includes: the first and second clamping claws 41 and 42 of the clamping assembly 4 clamp both ends of the carrier film 400, respectively. The first holding jaw 41 includes a first upper holding jaw 411 and a first lower holding jaw 412, and the first upper holding jaw 411 and the first lower holding jaw 412 are relatively moved in the first direction Z to clamp and fix one end of the carrier film 400. The second holding jaw 42 includes a second upper holding jaw 421 and a second lower holding jaw 422, and the second upper holding jaw 421 and the second lower holding jaw 422 are relatively moved in the first direction Z to hold and fix the other end of the carrier film 400.
The carrier film 400 includes a first face 4001 facing the curved cover plate 200 and a second face 4002 facing away from the curved cover plate 200. The first face 4001 carries a flexible screen 300 thereon. The first surface 4001 and the second surface 4002 are parallel. The flexible screen 300 is located approximately midway between the first gripper jaw 41 and the second gripper jaw 42.
It is understood that step 010 and step 020 can be performed in tandem without limitation, or can be performed simultaneously.
Referring to fig. 46, fig. 46 is a third schematic structural view corresponding to the bonding method shown in fig. 43. Fig. 46 corresponds to step 010 and step 040.
Step 040: the clamping assembly 4 and the attaching assembly 5 are relatively moved to the pre-attaching position, so that the carrier film 400 is kept in a tensioned state and the second surface 4002 contacts the attaching pad 53 of the attaching assembly 5. Wherein, laminating subassembly 5 still includes first slider 51 and second slider 52, and first slider 51 and second slider 52 support laminating pad 53 jointly. At this time, the first slider 51 and the second slider 52 are in a closed state.
When the clamping assembly 4 and the attaching assembly 5 are in the pre-attaching position, the carrier film 400 and the flexible screen 300 on the carrier film 400 are contoured, and the shape of the flexible screen 300 corresponds to the shape of the support area of the attaching pad 53. The support area of the bonding pad 53 is an area where the bonding pad 53 contacts the carrier film 400. At this time, the shape of the bent flexible screen 300 may be more suitable for the subsequent steps by the structural design of the attaching assembly 5 of the attaching apparatus 100, so as to improve the attaching quality and the attaching efficiency.
The process of "the clamping component 4 and the attaching component 5 move relatively to the pre-attaching position" has various implementation manners, for example:
In one implementation, as shown in fig. 46, the process of moving clamping assembly 4 and attaching assembly 5 relative to each other to the pre-attaching position includes:
step 041: the holding member 4 drives the two ends of the carrier film 400 to move toward the two sides of the bonding pad 53.
The clamping assembly 4 drives the two ends of the carrier film 400 to perform interpolation motion, so as to be close to the two side portions of the attaching pad 53. For example, the first clamping claw 41 has a degree of freedom in the first direction Z and the second direction X, and the first clamping claw 41 drives one end of the carrier film 400 to move (i.e., move downward) away from the curved cover plate 200 and move toward the first side 531 of the attaching pad 53. The second clamping jaw 42 has freedom degrees in the first direction Z and the second direction X, and the second clamping jaw 42 drives the other end of the carrier film 400 to move away from the curved cover plate 200 (i.e. move downward) and move toward the second side 532 of the bonding pad 53. That is, the holding member 4 drives the two ends of the carrier film 400 to move in the first direction Z and the second direction X toward the two sides of the attaching pad 53. The movement of the end of the carrier film 400 in the first direction Z and the movement in the second direction X by the clamping assembly 4 are not limited to be in sequence.
Step 042: the abutting assembly 5 moves in a direction approaching the mounting assembly 3.
The first slider 51, the second slider 52 and the bonding pad 53 of the bonding module 5 move synchronously along the first direction Z toward the mounting module 3. When the step 041 is performed, the step 042 may be performed synchronously to accelerate the relative movement of the clamping component 4 and the attaching component 5 to the pre-attaching position, so as to improve the attaching efficiency of the curved cover plate 200 and the flexible screen 300 in the attaching method.
In this implementation, because the pre-fitting position relationship is realized by moving the clamping assembly 4 and the fitting assembly 5, the respective moving strokes of the clamping assembly 4 and the fitting assembly 5 are small, which is beneficial to reducing the volumes of the driving parts or the transmission parts of the clamping assembly 4 and the fitting assembly 5 of the fitting device 100, thereby reducing the volume and the cost of the fitting device 100. In addition, the mode that the clamping component 4 and the attaching component 5 move simultaneously can also shorten the time length that the clamping component 4 and the attaching component 5 move in place, so that the attaching efficiency of the attaching method is improved.
The first slider 51 includes a first supporting surface 511, a first transition surface 512 and a first side surface 513 sequentially connected to each other. The second slider 52 includes a second supporting surface 521, a second transition surface 522 and a second side surface 523, which are sequentially connected. The first side surface 513 and the second side surface 523 are disposed opposite to each other and both are recessed toward each other. The attaching pad 53 contacts the first transition surface 512, the first supporting surface 511, the second supporting surface 521 and the second transition surface 522.
At this time, since the first side surface 513 and the second side surface 523 are recessed toward each other, that is, the first side surface 513 and the second side surface 523 are waisted, a portion corresponding to the first transition surface 512 forms a vertex angle with a smooth surface, and a portion corresponding to the second transition surface 522 forms a vertex angle with a smooth surface. The vertex angles of the first slider 51 and the second slider 52 can be matched with the bending angle of the edge area of the curved cover plate 200, so that the flexible screen 300 and the curved cover plate 200 can be better supported to be attached in the subsequent attaching process.
When the clamping assembly 4 and the attaching assembly 5 move relatively to the pre-attaching position, two ends of the carrier film 400 are respectively located on a side of the first supporting surface 511 facing the first side surface 513 and a side of the second supporting surface 521 facing the second side surface 523, and a distance S3 between the two ends of the carrier film 400 is smaller than a distance S4 between the two ends of the flexible screen 300. That is, two ends of the carrier film 400 are located in the concave regions formed by the first side surface 513 and the second side surface 523, at this time, two ends of the flexible screen 300 can be better close to the vertex angle of the first slider 51 and the vertex angle of the second slider 52, and the profiling angle of two ends of the flexible screen 300 is larger, so as to adapt to the fitting requirement of the curved cover plate 200 with a larger bending angle (for example, greater than or equal to 60 °) in the edge region.
In other embodiments, when the attaching method is used to attach the curved cover plate 200 and the flexible screen 300 having smaller bending angles in the edge regions, the two ends of the carrier film 400 do not have to be moved into the concave regions formed by the first side surface 513 and the second side surface 523, and the flexibility of the positions of the two ends of the carrier film 400 is higher. Likewise, the first side 513 and the second side 523 may not be designed to be concave, but may be designed to be flat.
In other embodiments, step 041 and step 042 may also be implemented in tandem without limitation.
In other embodiments, please refer to fig. 47, fig. 47 is a schematic structural diagram of the structure shown in fig. 46 in another embodiment. In step 041, the clamping assembly 4 drives the two ends of the carrier film 400 to move along the second direction X toward the two sides of the attaching pad 53. In this embodiment, since the attaching assembly 5 can move along the first direction Z and the holding assembly 4 can move along the second direction X, in the relative movement process of the attaching assembly 5 and the holding assembly 4, the objectives of relative movement in the first direction Z and relative movement in the second direction X can be achieved, so that when the holding assembly 4 and the attaching assembly 5 are in the pre-attaching position relationship, the specific positions of the two are more diversified, and the attaching requirements of the curved surface cover plate 200 and the flexible screen 300 with different sizes or shapes in a wider range can be met.
In another implementation, the process of moving clamping assembly 4 and attaching assembly 5 to the pre-attaching position includes:
step 041': the holding member 4 drives the two ends of the carrier film 400 to move toward the two sides of the bonding pad 53.
This step can be implemented as step 041 described above. In this implementation, the attaching assembly 5 does not need to move, and the clamping assembly 4 and the attaching assembly 5 move to the pre-attaching position through the movement of the clamping assembly 4 alone, so that the design of the freedom degree of the attaching assembly 5 can be reduced, the structure of the attaching device 100 is simpler, the cost is lower, the process steps of the attaching method are simplified, and the controllability is improved. This implementation is applicable to the fitting process of the curved cover plate 200 having a large bending angle in the edge region, and may also be applicable to the fitting process of the curved cover plate 200 having a small bending angle in the edge region.
In another implementation, the process of moving the clamping assembly 4 and the attaching assembly 5 to the pre-attaching position includes:
step 042': the abutting assembly 5 moves in a direction approaching the mounting assembly 3.
This step can be implemented as described in step 042 above. In this implementation, the clamping assembly 4 does not need to move, and the clamping assembly 4 and the attaching assembly 5 move to the pre-attaching position through the movement of the attaching assembly 5, so that the design of the degree of freedom of the clamping assembly 4 can be reduced, the structure of the attaching device 100 is simpler, the cost is lower, the process steps of the attaching method are simplified, and the controllability is improved. This embodiment is mostly used to implement the attaching process of the curved cover plate 200 with a small bending angle in the edge area.
It is to be understood that the applicator assembly 5 structure of fig. 44-47 may employ the applicator assembly 5 of the first-third embodiments of the applicator apparatus 100 of the previous embodiments.
Referring to fig. 48, fig. 48 is a fourth schematic structural view corresponding to the bonding method shown in fig. 43. Fig. 48 corresponds to step 060. The attaching assembly 5 in fig. 48 corresponds to the attaching assembly 5 of the aforementioned attaching apparatus 100 in the first embodiment.
Step 060: the attaching member 5 and the mounting member 3 are brought close to each other in the first direction Z to a preliminary attaching position to attach the middle region of the curved cover 200 to the middle region of the flexible screen 300. At this time, the first slider 51 and the second slider 52 are kept in a closed state. Conformable pad 53 remains naturally flat or taut. The first slider 51, the second slider 52 and the bonding pad 53 of the bonding module 5 are synchronously operated and relatively close to the mounting base 31 of the mounting module 3. The first support surface 511 of the first slider 51 and the second support surface 521 of the second slider 52 support the middle region of the flexible screen 300 to be attached to the middle region of the curved cover plate 200 through the attachment pad 53.
It is understood that the dividing positions of the middle area and the edge area of the curved cover plate 200 are not strictly defined in the embodiments of the present application, and the dividing positions of the middle area and the edge area of the flexible screen 300 are also not strictly defined, but simply define that the middle area is located in the middle and the edge areas are located at both sides of the middle area.
Wherein the process of "approaching the attaching assembly 5 and the mounting assembly 3 to the preliminary attaching position in the first direction Z to each other" includes:
step 061: the mounting assembly 3 moves in a first direction Z toward the abutment assembly 5. Specifically, the mounting base 31 drives the curved cover plate 200 to approach the attaching pad 53 of the attaching assembly 5 along the first direction Z.
Step 062: engaging assembly 5 and gripping assembly 4 move synchronously in a first direction Z, towards the direction of approach of mounting assembly 3. Specifically, the first clamping claw 41 and the second clamping claw 42 bring the carrier film 400 and the flexible screen 300 close to the mounting base 31 of the mounting assembly 3 along the first direction Z synchronously with the first slider 51, the second slider 52 and the attaching pad 53.
In this embodiment, step 061 and step 062 may be performed simultaneously to increase the speed of the attaching member 5 and the mounting member 3 moving to the preliminary attaching position, thereby improving the attaching efficiency of the curved surface cover plate 200 and the flexible screen 300 of the attaching method.
In this embodiment, since the clamping assembly 4, the attaching assembly 5, and the mounting assembly 3 all realize the preliminary attaching position relationship by moving, the respective moving strokes of the clamping assembly 4, the attaching assembly 5, and the mounting assembly 3 are small, which is beneficial to reducing the volumes of the driving parts 5901 or the transmission parts of the clamping assembly 4, the attaching assembly 5, and the mounting assembly 3 of the attaching apparatus 100, thereby reducing the volume and the cost of the attaching apparatus 100.
In other embodiments, the process of "the attaching member 5 and the mounting member 3 approach each other to the preliminary attaching position in the first direction Z" may include step 061 or step 062. At this time, by moving the mounting assembly 3 or the attaching assembly 5 and the clamping assembly 4, the attaching assembly 5 and the mounting assembly 3 can be close to each other to the preliminary attaching position in the first direction Z, so that the driving mechanism and the transmission mechanism of the mounting assembly 3 or the attaching assembly 5 and the clamping assembly 4 can be simplified, the cost of the attaching device 100 can be reduced, the process steps of the attaching method can be simplified, and the controllability can be improved.
Referring to fig. 49, fig. 49 is a schematic structural diagram of the structure shown in fig. 48 in another embodiment. The attaching assembly 5 in fig. 49 corresponds to the attaching assembly 5 of the aforementioned attaching apparatus 100 in the second embodiment. Most technical contents of the present embodiment that are the same as those of the previous embodiment are not described again.
The main differences between this embodiment and the foregoing embodiment are: the conformable assembly 5 also includes a support block 550. The supporting block 550 is located between the first slider 51 and the second slider 52. When the first slider 51 and the second slider 52 approach the supporting block 550 to the closed state, the first supporting surface 511 of the first slider 51, the third supporting surface 5503 of the supporting block 550, and the second supporting surface 521 of the second slider 52 are spliced into a continuous and flat supporting surface, and the supporting surface supports the attaching pad 53. That is, the first slider 51, the supporting block 550 and the second slider 52 are attached to the middle region of the curved cover plate 200 together through the attaching pad 53 supporting the middle region of the flexible screen 300.
Referring to fig. 50, fig. 50 is a schematic structural view of the structure shown in fig. 48 in a further embodiment. The attaching assembly 5 in fig. 50 corresponds to the attaching assembly 5 of the aforementioned attaching apparatus 100 in the third embodiment. Most technical contents of the present embodiment that are the same as those of the previous embodiment are not described again.
The main differences between this embodiment and the foregoing embodiment are: conformable assembly 5 also includes a conformable platform 54 and a squeeze block 580. The first slider 51 and the second slider 52 are slidably mounted to the attaching platform 54. The pressing block 580 is installed on the attaching platform 54 and located between the first slider 51 and the second slider 52. When the pressing block 580 is in the ejecting state, the pressing block 580 protrudes in a direction away from the attaching platform 54 relative to the first slider 51 and the second slider 52, the first slider 51 and the second slider 52 are in the closing state, and the distance between the first slider 51 and the second slider 52 is small. When the pressing block 580 is forced to move to a pressing state in a direction close to the attaching platform 54, the first slider 51 and the second slider 52 are pushed away towards two sides by the pressing block 580, the first slider 51 and the second slider 52 are in an opening state, and the distance between the first slider 51 and the second slider 52 is larger.
When the attaching member 5 and the mounting member 3 are brought close to each other to the preliminary attaching position in the first direction Z, the pressing block 580 is protruded in a direction away from the attaching platform 54 with respect to the first slider 51 and the second slider 52, and the middle region of the flexible screen 300 is attached to the middle region of the cover plate with the support of the pressing block 580. At this time, the pressing block 580 is attached to the middle region of the curved cover plate 200 away from the top surface 5803 of the attaching platform 54 through the middle region of the attaching pad 53 supporting the flexible screen 300. In addition, neither the first slider 51 nor the second slider 52 is yet attached and supported.
Here, in the present embodiment, when the attaching platform 54 is a fixed platform, the attaching member 5 and the mounting member 3 are brought close to each other to the preliminary attaching position by step 061.
Referring to fig. 51, fig. 51 is a fifth structural schematic view corresponding to the bonding method shown in fig. 43. Fig. 51 corresponds to step 070. The attaching assembly 5 in fig. 51 corresponds to the attaching assembly 5 of the aforementioned attaching apparatus 100 in the first embodiment. The structure shown in fig. 51 corresponds to fig. 48.
Step 070: the first slider 51 and the second slider 52 are away from each other in the second direction X to an open state, so that the edge region of the curved cover plate 200 is attached to the edge region of the flexible screen 300. Wherein the second direction X is perpendicular to the first direction Z.
At this time, the first transition surface 512 of the first slider 51 and a portion of the first supporting surface 511 close to the first transition surface 512, the second transition surface 522 of the second slider 52 and a portion of the second supporting surface 521 close to the second transition surface 522 are attached to the edge region of the flexible screen 300 by the edge region of the curved cover 200 supported by the attaching pad 53, so that the curved cover 200 and the flexible screen 300 are completely attached.
Because the first transition surface 512 and the second transition surface 522 are in the shape of the inward-contracting profile design of the curved portion of the edge region of the curved cover plate 200, the vertex angle of the first slider 51 corresponding to the first transition surface 512 and the vertex angle of the second slider 52 corresponding to the second transition surface 522 can support the edge region of the curved cover plate 200 to be attached to the edge region of the flexible screen 300 through the attachment pad 53, and the problem of bubbles generated when the edge of the flexible screen 300 is attached to the curved cover plate 200 before the middle portion 533 of the flexible screen 300 can be avoided, so that the attachment quality of the flexible screen 300 and the curved cover plate 200 is better.
Optionally, the attaching assembly 5 further includes a slider driving assembly 55, and when the first slider 51 and the second slider 52 are away from each other in the second direction X to the open state, "the slider driving assembly 55 drives the first slider 51 and the second slider 52 to move.
Referring to fig. 10, the slider drive assembly 55 includes a first slider drive member 551 and a second slider drive member 552. The first slider driving member 551 is used for driving the first slider 51 to move. The second slider drive 552 is used to drive the second slider 52 in motion. In the process of driving the first slider 51 and the second slider 52 to move by the slider driving assembly 55, the first slider 51 and the second slider 52 may move away from each other at the same time, or one of them may move away from each other first and the other may move away from each other again. Since the first slider driving member 551 and the second slider driving member 552 can be controlled independently of each other, the sequence of the moving time of the first slider 51 and the second slider 52 is not strictly limited by the attaching method, and the moving scheme of the first slider 51 and the second slider 52 is flexible.
Optionally, with continued reference to fig. 51, in the process of "the first slider 51 and the second slider 52 are away from each other in the second direction X to the opened state", the clamping assembly 4 and the applying assembly 5 are relatively moved to the applying position, so that the carrier film 400 is kept in the tensioned state, and a partial region of the carrier film 400 is pushed by the first slider 51 and the second slider 52 and is close to the edge region of the curved cover plate 200.
In this embodiment, since the distance between the first slider 51 and the second slider 52 is formed and increased in the process of transforming the first slider 51 and the second slider 52 from the closed state to the open state, in order to not damage the flexible panel 300, a part of the area of the carrier film 400 needs to be moved from the position originally facing the first side surface 513 or the first transition surface 512 to the position close to the position facing the first supporting surface 511, and another part of the area of the carrier film 400 needs to be moved from the position originally facing the second side surface 523 or the second transition surface 522 to the position close to the position facing the second supporting surface 521, thereby compensating the area of the carrier film 400 facing the distance between the first slider 51 and the second slider 52. In short, a partial region of the carrier film 400 needs to be moved from a lateral position of the attachment pad 53 to a top position near the attachment pad 53 for displacement compensation of the carrier film 400.
The area of the carrier film 400 for displacement compensation is pushed by the first slider 51 and the second slider 52 to bring the edge area of the flexible screen 300 close to the edge area of the curved cover plate 200, so as to be attached to the edge area of the curved cover plate 200. The carrier film 400 is always kept in a tension state in the process of attaching the flexible screen 300 to the curved cover plate 200, so that the attaching quality of the flexible screen 300 and the curved cover plate 200 is high, and the yield of the screen formed by attaching the flexible screen 300 and the curved cover plate 200 is high.
Wherein, the process of "clamping component 4 and laminating component 5 relatively move to the laminating position" includes:
step 071: the clamping assembly 4 drives the two ends of the carrier film 400 to move away from each other in the second direction X. The both ends of the carrier film 400 refer to both ends of the carrier film 400 sandwiched by the first and second clamping claws 41 and 42.
In step 060, the two ends of the carrier film 400 clamped by the clamping assembly 4 are located at two sides of the attaching assembly 5, that is, located at two sides of the first slider 51 and the second slider 52, so that in the process that the first slider 51 and the second slider 52 are away from each other, the two ends of the carrier film 400 are driven by the clamping assembly 4 to be away from each other in the second direction X, which can prevent the two ends of the clamping assembly 4 and the carrier film 400 from obstructing the sliding motion of the first slider 51 and the second slider 52, and thus the motion of the first slider 51 and the second slider 52 away from each other can be smoothly performed.
In addition, when one end of the first clamping claw 41 of the clamping assembly 4 clamping the carrier film 400 is located in the concave region of the first side surface 513, and the other end of the second clamping claw 42 clamping the carrier film 400 is located in the concave region of the second side surface 523, the first clamping claw 41 and the second clamping claw 42 drive the two ends of the carrier film 400 to move away from each other in the second direction X, so that one end of the carrier film 400 can leave the concave region of the first side surface 513, and the other end of the carrier film 400 can leave the concave region of the second side surface 523, and a portion of the carrier film 400 located at the side position of the attaching pad 53 moves from an inclined state to a vertical state, thereby releasing a partial region for displacement compensation.
Step 072: the clamping assembly 4 drives the two ends of the carrier film 400 to approach the curved cover plate 200 along the first direction Z.
At this time, the first clamping claw 41 of the clamping assembly 4 clamps one end of the carrier film 400 near one side edge region of the curved cover plate 200, and the second clamping claw 42 clamps the other end of the carrier film 400 near the other side edge region of the curved cover plate 200, so that both ends of the carrier film 400 can release partial regions for displacement compensation.
Step 073: the mounting assembly 3 and the attaching assembly 5 move in the first direction Z simultaneously so that the curved cover plates 200 are close to both ends of the carrier film 400. The both ends of the carrier film 400 refer to both ends of the carrier film 400 sandwiched by the first and second clamping claws 41 and 42.
At this time, the mounting base 31 of the mounting unit 3, the first slider 51, the second slider 52, and the bonding pad 53 of the bonding unit 5 move in the first direction Z in synchronization. Both ends of the carrier film 400 can also release partial areas for displacement compensation.
In this embodiment, the attaching method moves the clamping assembly 4 and the attaching assembly 5 to the attaching position through one or both of steps 072 and 073 and step 071, so that the displacement of the movement of each component of the attaching apparatus 100 is small, thereby reducing the size and cost of the attaching apparatus 100. When one or both of steps 072 and 073 and step 071 are performed simultaneously, the clamping assembly 4 and the applying assembly 5 can be relatively moved to the applying position more quickly, so that the applying efficiency of the applying method is higher.
Wherein, step 072 and step 073 may be implemented alternatively or both. When step 072 and step 073 are both performed, both steps may be performed simultaneously or one after the other.
In other embodiments, the process of "moving clamp assembly 4 and conformable assembly 5 relative to each other to the conformable position" can be performed by step 071 alone (where conformable assembly 5 and mount assembly 3 do not move in first direction Z), or by one or both of steps 072 or 073 (where clamp assembly 4 does not move in second direction X).
It can be understood that, when the step 071 is not provided in the step "relative movement of the clamping assembly 4 and the attaching assembly 5 to the attaching position", in the step 040 "relative movement of the clamping assembly 4 and the attaching assembly 5 to the pre-attaching position", a sufficient distance needs to be reserved between a position where the first clamping claw 41 of the clamping assembly 4 clamps the end of the carrier film 400 and the first slider 51, so that the first slider 51 does not interfere with the end of the carrier film 400 in the process of moving away from the second slider 52. Similarly, a sufficient distance is required to be reserved between the position where the second clamping claw 42 of the clamping assembly 4 clamps the other end of the carrier film 400 and the second slider 52, so that the second slider 52 does not interfere with the other end of the carrier film 400 in the process of moving away from the first slider 51.
Referring to fig. 52, fig. 52 is a schematic structural diagram of the structure shown in fig. 51 in another embodiment. The structure shown in fig. 52 corresponds to fig. 48. Most technical contents of the present embodiment that are the same as those of the previous embodiment are not described again. In the present embodiment, the gripper assembly 4 has no degree of freedom in the first direction Z. At this time, the process of "relatively moving the holding member 4 and the applying member 5 to the applying position" may be performed by the step 073 alone, or by the steps 073 and 071. Specifically, the method comprises the following steps:
the process of relatively moving clamping assembly 4 and attaching assembly 5 to the attaching position includes:
the attaching member 5 and the mounting member 3 are moved in synchronization in the first direction Z so that the flexible screen 300 is close to both ends of the carrier film 400. The both ends of the carrier film 400 refer to both ends of the carrier film 400 sandwiched by the first and second clamping claws 41 and 42. This step corresponds to the aforementioned step 073.
Optionally, the process of "moving clamping assembly 4 and attaching assembly 5 relatively to each other to the attaching position" further includes:
the clamping assembly 4 drives the two ends of the carrier film 400 to move away from each other in the second direction X. This step corresponds to the aforementioned step 071.
Referring to fig. 53, fig. 53 is a schematic structural diagram of the structure shown in fig. 51 in a further embodiment. The attaching assembly 5 in fig. 53 corresponds to the attaching assembly 5 of the aforementioned attaching apparatus 100 in the second embodiment. The structure shown in fig. 53 corresponds to fig. 49. Most technical contents of the present embodiment that are the same as those of the previous embodiment are not described again.
Wherein, laminating assembly 5 may also include first pressure sensor 5501 and second pressure sensor 5502. The fitting assembly 5 can acquire the pressure between the supporting block 550 and the second slider 52 and the pressure between the supporting block 550 and the second slider 52 through the first pressure sensor 5501 and the second pressure sensor 5502, so as to feed back the fitting pressure when the edge region of the flexible screen 300 supported by the first slider 51 and the second slider 52 is fitted with the edge region of the curved cover plate 200, and further diagnose whether the fitting process is qualified through the fitting pressure, and also can adjust the parameters (such as the parameters of the driving assembly) of the fitting equipment 100 through the fitting pressure in time, so as to optimize the fitting process of the curved cover plate 200 and the flexible screen 300 in time, and improve the fitting quality.
In the process of moving the first slider 51 and the second slider 52 away from each other in the second direction X to the splayed state, the drive parameter of the first slider driver is adjusted according to the detection value of the first pressure sensor 5501, and the drive parameter of the second slider driver is adjusted according to the detection value of the second pressure sensor 5502. At this time, the attaching process of the edge area of the flexible screen 300 and the edge area of the curved cover plate 200 is more accurate, and the attaching quality is higher.
Note that, in fig. 53, the attaching unit 5, the mounting unit 3, and the holding unit 4 may be moved in the same manner as in the embodiment shown in fig. 52. And will not be described in detail herein.
Referring to fig. 54, fig. 54 is a schematic structural diagram of the structure shown in fig. 51 in a further embodiment. The attaching assembly 5 in fig. 54 corresponds to the attaching assembly 5 of the aforementioned attaching apparatus 100 in the third embodiment. The structure shown in fig. 54 corresponds to fig. 50. Most technical contents of the present embodiment that are the same as those of the previous embodiment are not described again.
The process of "the first slider 51 and the second slider 52 move away from each other in the second direction X to the open state" includes:
the attaching assembly 5 and the mounting assembly 3 are close to each other to a completely attaching position in the first direction Z, the pressing block 580 moves to a direction close to the attaching platform 54 under the pressing of the curved cover plate 200, the first slider 51 and the second slider 52 are away from each other to an open state in the second direction X under the pressing of the pressing block 580, and the edge region of the flexible screen 300 is attached to the edge region of the curved cover plate 200 under the support of the first slider 51 and the second slider 52. The present embodiment is largely different from the foregoing embodiment in that the movement of the pressing block 580, the first slider 51, and the second slider 52 is a passive movement. The direction of passive movement is indicated by the dashed arrow in fig. 54.
Wherein the process of "approaching the attaching assembly 5 and the mounting assembly 3 to the completely attaching position in the first direction Z" includes: the mounting member 3 moves in the first direction Z in a direction approaching the attaching member 5. In this case, the bonding platform 54 may be a fixed platform, and the bonding apparatus 100 has a simple structure and low cost.
In other embodiments, when conformable platform 54 is a movable platform, proximity to mounting assembly 3 may also be achieved by movement of conformable assembly 5. At this time, the holding member 4 and the sticking member 5 move in synchronization.
It is understood that, without conflict, the displacement compensation manner of the carrier film 400 in the present embodiment may be the same as that of the foregoing embodiment.
Referring to fig. 55 and 56 together, fig. 55 is a sixth schematic structural view corresponding to the bonding method shown in fig. 43, and fig. 56 is a seventh schematic structural view corresponding to the bonding method shown in fig. 43.
After "the first slider 51 and the second slider 52 are moved away from each other in the second direction X to the open state" (step 070), the attaching method further includes:
step 080: the clamping assembly 4 drives the two ends of the carrier film 400 to approach the cover plate, so that the carrier film 400 is released from the tension state. At this time, the carrier film 400 is in a relaxed state, so as to avoid the carrier film 400 from being locally damaged or breaking the flexible screen 300 due to sudden stress change of the carrier film 400 when the clamping assembly 4 releases the carrier film 400.
Step 090: the chucking assembly 4 releases both ends of the carrier film 400. The first upper jaw 411 and the first lower jaw 412 of the first holding jaw 41 are moved away from each other to release one end of the carrier film 400. The second upper jaw 421 and the second lower jaw 422 of the second gripper jaw 42 are moved away from each other to release the other end of the carrier film 400. In addition, the attaching assembly 5 can be far away from the mounting assembly 3, so that the attaching pad 53 is separated from the carrier film 400. When the attaching assembly 5 is far away from the mounting assembly 3, the first slider 51 and the second slider 52 can be moved close to each other to be in a close state, so as to be convenient to withdraw.
Alternatively, between "moving the clamping assembly 4 and the fitting assembly 5 relatively to the pre-fitting position" (step 040) and "approaching the fitting assembly 5 and the mounting assembly 3 to the preliminary fitting position in the first direction Z" (step 060), the fitting method further includes:
a sealed working chamber is formed, and the curved cover plate 200 and the flexible screen 300 are accommodated in the working chamber. And, evacuating the working chamber.
In this embodiment, the curved cover plate 200 and the flexible screen 300 can be attached to each other in a vacuum environment, so that bubbles and foreign matters are reduced, and the attachment quality is improved.
After "the first slider 51 and the second slider 52 are moved away from each other in the second direction X to the opened state" (step 070), the attaching method further includes: the vacuum environment of the working chamber is released. And, opening the working chamber.
The present step may be performed before step 080, between step 080 and step 090, or after step 090.
Optionally, after "evacuating the working chamber", the attaching method further includes (see fig. 29 and 30):
and the monitoring camera assembly 6 shoots the laminating process of the curved cover plate 200 and the flexible screen 300 along the third direction Y. Wherein the third direction Y is perpendicular to the first direction Z and the second direction X. The attaching process includes one or both of attaching a middle region of the curved cover plate 200 to a middle region of the flexible screen 300 or attaching an edge region of the curved cover plate 200 to an edge region of the flexible screen 300.
In this embodiment, the curved cover plate 200 and the flexible screen 300 which are poorly attached can be intercepted in time by monitoring the image information acquired by the camera assembly 6, and the user can also analyze the attaching process, so that the attaching process steps are improved, and the attaching quality is improved.
Alternatively, after "the clamping assembly 4 releases both ends of the carrier film 400" (step 090), the attaching method further includes:
0100: the curved cover plate 200 is removed from the mounting assembly 3. At this time, the member (e.g., the flexible panel 300) attached to the curved cover 200 is removed along with the curved cover 200.
Step 0110: the carrier film 400 is torn away from the flexible screen 300.
Wherein, the sequence of step 0100 and step 0110 is not limited. In other embodiments, the mounting assembly 3 may release the curved cover plate 200 during the "de-vacuuming the working chamber" step. In this way, when the mounting assembly 3 is away from the attachment assembly 5, the curved cover 200 and the flexible screen 300 are positioned on the attachment assembly 5, and the curved cover 200 and the flexible screen 300 can be removed from the attachment assembly 5.
