Background

The OLED flexible liquid crystal display is a new display technology, and compared with the existing liquid crystal display, the OLED flexible liquid crystal display has the most important characteristics that the OLED flexible liquid crystal display not only can realize plane display, but also can realize bending deformation and curved surface display. Compared with the common flat-panel liquid crystal display, the production process flow is greatly simplified, the energy consumption is lower, the service life is longer, and the method is the mainstream direction of the development of the future display technology.

In the production process of the OLED display screen, the whole large flexible display screen is required to be cut into a small flexible display screen (Cell) shown in figure 1 by laser according to typesetting, and the small flexible display screen consists of an upper protective film, a middle PI layer and a lower protective film. And the upper protective film is cut off along the cutting seam by laser, the middle PI layer is not damaged, and finally the waste edge film to be removed is stripped and removed from the Cell.

In the current production process of the OLED, the waste edge peeling and removing of the small flexible display screen (cell) is mostly performed by peeling and removing after adsorbing and bonding a waste edge film by using a roller, for example, the published patent scheme is as follows: a method and a device (application number: 201410018044.7) for peeling a flexible display film are disclosed, which are used to solve the problem that when the flexible display film with a display structure is peeled off from a substrate, the flexible display film may be damaged greatly, so that the manufactured flexible display device cannot display.

Detailed Description

For a further understanding of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings and examples.

The small flexible display 500 shown in fig. 1 is composed of three parts, namely, a lower protective film 501, a PI layer 502 located in the middle, and an upper protective film 503. Wherein, the upper protective film 503 is cut off along the cutting seam by laser without damaging the middle PI layer, thereby forming a waste edge film 504 at the edge, and finally peeling off and removing the waste edge film 504 to be removed from the display screen. However, the conventional peeling apparatus has problems such as poor peeling effect and the possibility of generation of wrinkles and bubbles. The present invention provides a number of solutions and illustrates different solutions by means of different embodiments.

In the present specification, the terms "upper", "lower", "left", "right" and "middle" are used for clarity of description, and are not used to limit the scope of the present invention, and the relative relationship between the terms and the terms is not limited to the scope of the present invention.

Example 1

Referring to fig. 2, the film peeling mechanism of the present embodiment includes a clamping jaw mechanism 320, a film lifting assembly and a peeling element, wherein the film lifting assembly is used for driving the peeling element to move relative to the clamping jaw mechanism and enabling the peeling element to penetrate into the waste selvage film to form an arch. As a specific implementation manner, the film removing assembly in this embodiment includes a film removing driving mechanism 220, in implementation, the film removing driving mechanism 220 and the clamping jaw mechanism 320 are both installed on the base 131, a horizontal sliding base 230 capable of moving horizontally is arranged in the film removing driving mechanism 220, and a peeling element 310 is installed on the horizontal sliding base 230 and is used for arching the waste edge film 504 to be peeled; the gripper mechanism 320 is used to grip the arched waste-edge film 504.

Specifically, the base 131 serves as a mounting base, and may be coupled to different portions of a particular user device, or may be mounted to other devices to achieve different movements. For example, by connecting the base 131 to the lifting mechanism, the entire peeling mechanism can be lifted and lowered; by connecting the base 131 to a horizontally moving drive, the entire peeling mechanism can be moved horizontally. The clamping jaw mechanism 320 may be directly connected to the base 131, or may be connected to the base 131 through other intermediate mechanisms, without specific limitation.

The film-lifting driving mechanism 220 may adopt a linear motor slide rail, a screw rod slide rail, etc., and taking a screw rod slide rail as an example, the film-lifting driving mechanism 220 may specifically include a driving motor, a transmission screw rod and a guide rail, and the transmission screw rod is horizontally disposed. The horizontal sliding base 230 is provided with a screw rod pair, and is matched with the transmission screw rod and the guide rail, so that the horizontal sliding base 230 can be driven by the driving motor to horizontally move along the screw rod direction.

Further, a tool holder 311 is installed on the horizontal sliding base 230, a vertically arranged peeling element 310 is installed on the tool holder 311, and the bottom end of the peeling element 310 can be set as a tip end for piercing the waste edge film 504 to be peeled. Since the peeling element 310 and the holder 311 are generally fixedly installed, a holder installation plate 312 may be disposed between the holder 311 and the horizontal sliding base 230 to implement installation of the peeling element 310 for convenience of fixing.

As other embodiments, the peeling element 310 may have other blade structure, such as two tips arranged in parallel at the bottom of the peeling element, and the parallel direction of the two tips may be the same as or perpendicular to the moving direction of the peeling element during peeling operation. The upper section of the peeling member 310 may have a rod-like or plate-like structure or the like, and the main purpose is to pierce the waste film with the tip of the lower end, and the connecting portion of the peeling member 310 is not particularly limited.

The clamping jaw mechanism 320 in this embodiment includes a connecting arm 322, a clamping jaw driving mechanism 321, and a clamp body 323, where the clamping jaw driving mechanism 321 is used to control the clamp body 323 to open and close, and may adopt a hydraulic, pneumatic, or electric driving structure, and preferably, may adopt an electric clamping jaw driving mechanism. The clamp body 323 consists of two clamps, and the clamp body 323 can be controlled to close the clamped object through a clamping jaw driving mechanism.

The jaw driving mechanism 321 is connected to the base 131 via a connecting arm 322, so that the jaw driving mechanism 321 does not move relative to the base 131. While the stripping elements 310 are able to move horizontally relative to the clamp body 323.

It should be noted that, since the peeling element 310 can only move horizontally relative to the clip body 323, in order to make the peeling element 310 penetrate into the waste edge film 504, the lower end of the peeling element 310 needs to protrude from the bottom surface of the clip body 323 by a distance smaller than the thickness of the waste edge film 504.

When the film peeling device is used, the driving base 131 descends, the peeling element 310 pierces the waste edge film 504 when the clamp 323 presses the upper protective film 503, and with reference to fig. 3, the peeling element 310 is driven by the film lifting driving mechanism 220 to move towards the clamp 323, so that the waste edge film 504 is separated from the upper protective film 503 and arched, the waste edge film 504 can be clamped by driving the clamp 323, and the waste edge film 504 can be torn off by moving the base 131 or the lower bearing table.

Example 2

Referring to fig. 4, the film peeling mechanism of the present embodiment is further provided with a Z-axis pair driving mechanism 210, wherein the Z-axis pair driving mechanism 210 is used for driving the peeling element 310 to move up and down.

Fig. 4 provides a specific mounting position of the Z-axis pair driving mechanism 210, in this embodiment, the Z-axis pair driving mechanism 210 is fixed on the base 131, the lifting plate 211 is provided in the Z-axis pair driving mechanism 210, and the film lifting driving mechanism 220 is mounted on the lifting plate 211 for moving the peeling member 310 up and down relative to the gripper mechanism 320.

The Z-axis pair driving mechanism 210 may adopt driving manners of different forms and different structures, and its main purpose is to ensure that the lifting plate 211 can move up and down, for example, a linear motor guide rail may be adopted to drive the lifting plate 211 to move up and down. The elevating plate 211 can move up and down by the power of the Z-axis pair driving mechanism 210.

The peeling member 310 can be driven to move up and down by the Z-axis sub-driving mechanism 210 by attaching the peeling driving mechanism 220 to the lifting plate 211. By cooperating the film-lifting drive mechanism 220 and the Z-axis pair drive mechanism 210, the up-and-down movement and the horizontal movement of the peeling member 310 can be realized.

Example 3

Referring to fig. 5, the film peeling mechanism of the present embodiment is further characterized by further comprising a distance measuring device 330, wherein the distance measuring device 330 moves synchronously with the peeling element 310. The distance measuring device 330 is used to detect the height from the waste film 504 before peeling, and an optical distance measuring device, such as a laser distance measuring device, may be used.

When the device is used, the distance measuring device 330 is moved to the lower cutting position, then the required downward movement distance of the peeling element 310 is detected, then the peeling element 310 is moved to the lower cutting position, and then the peeling element 310 is pricked into the waste edge film 504 by matching with the base 131 and the Z-axis pair driving mechanism 210. The peeling member 310 is driven by the film raising driving mechanism 220 to move forward slowly for a certain distance, so that the waste edge film 504 is raised to form a semicircular arc shape and then stops, the raised waste edge film 504 can be clamped by the clamp body 323, and then the peeling operation can be performed.

Example 4

Fig. 5 also shows an embodiment of the film-drawing driving mechanism 220. In this embodiment, the film-drawing driving mechanism 220 further comprises a servo motor 221, a transmission belt 222 and a shield 223, the servo motor 221 is fixed on the lifting plate 211 and is located above the lifting plate 211, the guide rail and the lead screw in the film-drawing driving mechanism 220 are mounted on the lifting plate and are located at the middle-lower position, and transmission is performed between the lead screw and the servo motor 221 through the transmission belt 222. Further, a shield 223 is covered on the outer side of the belt 222 for safety protection.

The state of the position of the peeling element 310 when piercing the waste edge film 504 is shown in fig. 6; fig. 7 shows the state that the waste-edge film 504 is arched in an arc shape by the peeling member 310, and the operation principle of the peeling mechanism can be clearly shown by two structural changes.

Example 5

Referring to fig. 8, this embodiment can also realize the horizontal movement and the vertical movement of the peeling element 310, except that in this embodiment, the positions of the film-lifting driving mechanism 220 and the Z-axis secondary driving mechanism 210 are exchanged, the film-lifting driving mechanism 220 is fixedly mounted on the base 131, the Z-axis primary driving mechanism 130 is mounted on the horizontal sliding base 230, and the film-lifting driving mechanism 220 can drive the Z-axis primary driving mechanism 130 to horizontally move in the same direction.

The Z-axis pair driving mechanism 210 is provided with a lifting plate 211, and the stripping element 310 is fixedly mounted on the lifting plate 211, that is, the tool holder 311 of the stripping element 310 is mounted on the lifting plate 211, or the tool holder 311 is connected with the lifting plate 211 through a tool holder mounting plate 312.

In this embodiment, although the structural form is changed, the horizontal movement and the vertical movement of the peeling element 310 can be realized, and the peeling work can be normally performed.

Example 6

On the basis of the above embodiment, with reference to fig. 6 and 7, as a preferred embodiment, an interlayer pad 324 may be disposed on the clamping surface of the clamp body 323. The interlayer pad 324 may be made of rubber, which is beneficial to protect the display screen 500 and prevent the display screen 500 from being damaged during the operation of the clip body.

Example 7

In this embodiment, on the basis of embodiment 6, the interlayer pad 324 protrudes from the bottom surface of the clip body 323, or a gasket is disposed on the bottom surface of the clip body 323, and the gasket and the interlayer pad 324 may be made of rubber, or may be made of other soft materials, without specific limitation.

The interlayer pad or the gasket protruding from the bottom of the clamp body can play a certain role in buffering and protecting, and in addition, in the scheme that the peeling element is parallel to the clamping surface, the clamp body positioned above the upper protective film 503 can press the upper protective film 503, so that the upper protective film 503 at the edge part cannot be lifted in conjunction with the peeling of the waste edge film 504, and the phenomenon that the upper protective film 503 is folded can be avoided. This protective effect can be further optimized when using an interlayer gasket 324 or shim.

As a modification, the bottom surfaces of the two clips of the clip body 323 may be arranged not to be in the same plane, wherein the clip in contact with the upper protective film 503 is in a lower position, the other clip is mainly used for the waste edge film clipping, and the bottom surface position may be relatively high. When the clamp is used specifically, the clamp can press the upper protective film, or the clamp and the upper protective film are not contacted, and no specific requirement exists.

Example 8

In the above embodiments, the clamping surface of the clamp body 323 is parallel to the horizontal movement direction of the peeling element 310, and alternatively, the horizontal movement direction of the peeling element 310 may be perpendicular to the clamping surface of the clamp body 323.

Fig. 9 shows an embodiment in which the direction of movement of the peeling member 310 is perpendicular to the holding surface, and in this case, since the raising and holding are performed in the width direction of the waste film 504, the body 323 holds only a partial region of the waste film 504.

It should be noted that, in this embodiment, if the clip 323 still presses the upper protective film 503, the waste edge film 504 is also pressed, and the peeling member cannot raise the waste edge film 504, so that the clip 323 can be suspended above the upper protective film 503.

Referring to fig. 10, as a modification, the clips 323 may be positioned near the end portions of the waste film 504 where one clip is positioned at the outer end of the waste film 504 without contacting the waste film 504 and the other clip may press down the waste film 504, in this embodiment, it is easier to arch the waste film 504 since the waste film 504 is peeled off at a fixed length.

Example 9

In the embodiment, the clip 323 is further improved to solve the problem that the clip 323 presses the waste edge film 504 and cannot be arched in the embodiment 8.

As shown in fig. 11, in this embodiment, the bottom surface of the clip 323 has a step surface, the lowest surface can press the upper protective film 503, and the position of the clip opposite to the waste edge film 504 forms a gap due to the step surface, so that the peeling element 310 can normally arch the waste edge film 504.

In particular, depending on the position of the collet 323, for example, only one of the collet 323 can be configured with a stepped surface.

The jaw drive mechanism 321 in the above embodiments may be a pneumatic or hydraulic or electric drive. The Z-axis pair driving mechanism 210 and the film-drawing driving mechanism 220 may be a lead screw guide rail structure, a synchronous belt guide rail structure or a linear motor guide rail structure. As for the specific structure, the screw rod can be matched with the guide rail in specific implementation, and no specific requirement exists. The power element may be a stepping motor, a servo motor, or the like, and is not particularly limited.

A table 410 is provided under the base 131 of the device for carrying the display screen 500. More specifically, the table 410 is located below the peeling mechanism so that the peeling mechanism can move above. The stage 410 may be a stage having adsorption holes, for example, a porous ceramic stage or a metal microporous adsorption plate.

In this embodiment, the workbench 410 and the clamping jaw mechanism 320 can move relatively, and specifically, when the arrangement is performed, the workbench 410 may be fixed and the base 131 moves, or the base 131 may be fixed and the workbench 410 moves, so that the workbench 410 and the clamping jaw mechanism 320 move relatively, and the stripped waste edge film is removed through the relative movement. The relative movement referred to may be a horizontal movement or may have a certain tilting movement, without particular limitation.

During processing, one side of the display screen 500 with the waste edge film 504 can be arranged close to the edge, and the waste edge film 504 can be quickly removed after being peeled off.

Preferably, a waste bin 430 may be provided at one side of the table 410 for receiving the stripped waste mold.

The base is fixedly mounted on the Y-axis slide 121 to effect relative movement of the table 410 and the gripper mechanism 320. The Y-axis driving mechanism 120 may be driven by an electric, hydraulic, or pneumatic driving method, and the specific executing structure may be a screw rod, a belt transmission, etc., without specific limitation.

Example 12

The film peeling apparatus of this embodiment further includes a lifting platform 420, the lifting platform 420 is located at one side of the working platform 410 and is combined with the working platform 410 to form a processing platform, and during processing, the waste edge film 504 is located above the lifting platform 420.

The lifting platform 420 can be an electric lifting platform or a hydraulic lifting platform or a pneumatic lifting platform, i.e. the lifting platform is driven to move up and down by a corresponding power system. The elevating platform 420 is used as an auxiliary support, can be descended when not needed, can reduce the area of the worktable, and can prevent interference with other components.

Example 13

In the film peeling apparatus of the present embodiment, a Z-axis main driving mechanism 130 is provided for driving a base 131 to move up and down. Specifically, the Z-axis main driving mechanism 130 may be fixed to the Y-axis slide 121, and the base 131 is connected to the lifting member of the Z-axis main driving mechanism 130, so that the movement of the base 131 in two perpendicular directions may be realized.

Example 14

The film peeling device of the embodiment is further provided with a base 110 and a shaft driving mechanism 111, the base 110 is used as a mounting support of the whole device, the X-axis driving mechanism 111 is fixed on the base 110, an X-axis sliding seat 112 is arranged in cooperation with the X-axis driving mechanism 111, the Y-axis driving mechanism 120 is mounted on the X-axis sliding seat 112, the direction of a sliding rail of the Y-axis driving mechanism 120 is perpendicular to the direction of a sliding rail of the X-axis driving mechanism 111 and is parallel to the workbench 410, and the direction of a sliding rail of the Z-axis main driving mechanism 130 is perpendicular to the workbench 410.

In this embodiment, the X-axis driving mechanism 111, the Y-axis driving mechanism 120, and the Z-axis main driving mechanism 130 form a three-axis large-step motion assembly including two horizontal motion mechanisms and one vertical motion mechanism with respect to the work table, and the Z-axis sub-driving mechanism 210 and the film-drawing driving mechanism 220 form two small-inertia peeling assemblies including up-and-down motion and horizontal motion with respect to the work table, and are mainly used for fine-tuning the distance and position at the time of peeling.

In this embodiment, one motion scheme is:

after the small flexible display screen 500 is placed on the worktable 410, the lifting platform 420 is lifted to be coplanar with the worktable 410, and then the worktable 410 adsorbs the display screen 500. The X-axis driving mechanism 111 and the Y-axis driving mechanism 120 drive the distance measuring sensor 8 to the lower position of the slitter edge film 504, and the required descending height of the cutter head is measured.

Then the film lifting driving mechanism 220 drives the peeling element 310 to slowly advance a short distance along the peeling direction, the to-be-removed clamp body 323 on the display screen 500 is peeled and arched, the to-be-removed clamp body 323 stops after being arched to form a semicircular arc shape, and the arched to-be-removed clamp body 323 is clamped by the clamp body 323. The Z-axis main driving mechanism 130 drives the clamp 323 to stop after rising for a certain distance, the X-axis driving mechanism 111 and the Y-axis driving mechanism 120 drive the clamp 323 to completely strip and remove the waste edge film 504 to be removed from the display screen 500 and move to the position above the waste bin 430, and the clamp 323 is loosened to put the stripped and removed waste edge film 504 into the waste bin 430. And finally, automatically resetting each driving shaft of the stripping and removing mechanism to wait for the next action cycle.

The device has small inertia of the stripping part and adopts a micro-motion mechanism, so that the high-precision stable operation can be realized at the initial stage of stripping the waste edge film. After the waste edge film is arched, the waste edge film can be reliably clamped and peeled. Therefore, the stripping device adopting the stripping mechanism can stably strip and remove the waste edge film, cannot generate wrinkles and bubbles, cannot damage the functional layer, and is favorable for improving the product quality and the qualification rate.
