Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1a is a schematic structural view of a curved display screen attaching apparatus according to a first embodiment of the present invention. As shown in fig. 1a, the curved display screen attaching apparatus 10 is used for attaching a flexible display panel 20 to a curved cover 30, wherein the curved cover 30 includes a plane area a and an arc area B formed by extending an end of the plane area a. The curved display screen attaching device 10 comprises an elastic pressure head 11 and a pressing piece 12. The pressing part 12 is embedded in the elastic pressure head 11, that is, the pressing part 12 is tightly embedded in the elastic pressure head 11, the surface of the pressing part 12 is tightly contacted with the elastic pressure head 11, and the elasticity of the pressing part 12 is smaller than that of the elastic pressure head 11.
The elastic indenter 11 has a good elasticity, for example a block of silicone. The elastic pressure head 11 comprises the same surface structure as the curved cover plate 30 to be attached, i.e. the elastic pressure head 11 comprises an attachment plane a corresponding to the plane area a of the curved cover plate 301And a first arc-shaped surface B corresponding to the arc-shaped region B of the curved cover plate 301Wherein the abutting plane a of the elastic indenter 111Is usually slightly convex, the fitting plane a1Whether the center of (a) is slightly convex has no effect on the curved display screen engaging apparatus 10 provided herein and therefore the slight convexity is ignored herein. In this way, the flexible display panel 20 can be pressed into the curved cover 30 by the elastic pressing head 11, and the flexible display panel 20 and the curved cover 30 can be bonded together at one time.
The press 12 may be a rigid element, such as a metal block. The number, shape and position of the pressing elements 12 in the elastic pressing head 11 can be chosen according to the actual needs. The pressing part 12 can assist the elastic pressing head 11 in fitting, and is used for driving out bubbles and realizing secondary fitting in the fitting process of the elastic pressing head 11 or after the elastic pressing head 11 is fitted.
According to the curved display screen laminating device provided by the embodiment, when the elastic pressing head 11 is pushed upwards by an external force to press the flexible display screen 20 into the curved cover plate 30, since the elasticity of the pressing part 12 is smaller than that of the elastic pressing head 11, along with the deformation of the elastic pressing head 11, the pressing part 12 generates further pressure on the elastic pressing head 11, compared with the pressing by only relying on the elastic pressing head 11, the laminating pressure of the selected area (i.e. the position embedded into the pressing part 12) can be increased, and the laminating effect is improved. In one embodiment, as shown in FIG. 1a, the curved display screen engaging apparatus 10 further comprises a driving member 13. The driving member 13 is connected to the pressing member 12 for generating a pushing force directed to the pressing member 12 to drive a local area of the elastic pressing head 11 to bulge outwards.
The driving member 13 may be an electric, pneumatic or manual driving mechanism, such as a propeller, or an externally acting force transmitter, such as a push rod, in which case a separate external driving device, such as a propeller, is required to be engaged to apply force to the push rod. The number of driving members 13 and the number of pressing members 12 correspond one to one, or a plurality of pressing members 12 share one driving member 13, in which case the plurality of pressing members 12 move in synchronization. The driving member 13 may be located outside the elastic pressing head or inside the elastic pressing head, and may be selected according to the type and driving manner of the driving member, and is not limited in detail herein.
The application process of the curved surface display screen laminating device comprises the following steps: firstly, an external mechanism is utilized to push the elastic pressure head 11 to completely press the flexible display panel 20 into the curved cover plate 30, so that one-time lamination is realized; then, when the elastic pressure head 11 is pushed by an external mechanism, because the elasticity of the pressing part 12 is smaller than that of the elastic pressure head 11, the pressing part 12 drives the corresponding area of the elastic pressure head 11 to protrude outwards, or the driving part 13 applies a pushing force to the pressing part 12 to drive the corresponding area of the elastic pressure head 11 to protrude outwards, so that secondary fitting of the corresponding area is realized. Or, firstly, the elastic pressure head 11 is pushed to press the center of the flexible display panel 20 into the curved cover plate 30; secondly, the bonded part is bonded for the second time by using the pressing piece 12, and bubbles at the bonded part are expelled; according to the above process, the flexible display panel 20 is sequentially attached from the center to the periphery.
According to the curved surface display screen laminating device provided by the embodiment, the flexible display panel and the curved surface cover plate are laminated twice, the probability of defects such as bubbles and black spots in the laminating process is reduced, and the reliability of the laminated curved surface display screen is improved. Meanwhile, the elastic pressure head can also play a role in stress buffering, so that the flexible display panel is prevented from being damaged due to the fact that the rigid pressing piece is in direct contact with the flexible display panel.
In one embodiment, as shown in fig. 1a, the elastic indenter 11 includes an arc-shaped area Q, and the pressing member 12 is located in the arc-shaped area Q of the elastic indenter 11.
In the process of simply using the elastic pressure head 11 for laminating, the first arc-shaped surface b of the elastic pressure head 111Easily contact with the arc-shaped area B of the curved cover plate 30, or the first arc-shaped surface B1After contacting the arc-shaped area B, the elastic pressure head 11 applies uneven pressure to various parts on the arc-shaped area B, thereby causing the defects of the curved-surface display screen, such as bubbles, in the arc-shaped area B of the curved-surface cover plate 30. According to the curved display screen laminating device provided by the embodiment, the pressing piece 12 is arranged in the arc-shaped area Q of the elastic pressure head 11, so that the arc-shaped area B of the curved cover plate 30 and the first arc-shaped surface B of the elastic pressure head 11 are realized1The secondary laminating between the two parts utilizes the pressing part 12 to compensate the stress of the arc-shaped area B, and the laminating effect of the whole curved surface display screen is improved.
In one embodiment, as shown in FIG. 1b, which is a partial enlarged view of the curved display screen attaching apparatus shown in FIG. 1a according to an embodiment of the present invention, the pressing member 12 includes an arc surface b curved in the same direction as the arc area Q of the elastic pressing head 112The arc surface b2Is smaller than the radius of curvature R of the curved region Q of the elastic indenter.
In the case of an arc, the degree of curvature can be measured by the radius of curvature by providing the arc surface b of the pressing member 122Is smaller than the radius R of curvature of the arc-shaped area Q of the elastic indenter 11, the arc-shaped surface b of the elastic indenter 11 can be made1And the arc-shaped area B of the curved cover plate 30, thereby ensuring the attaching effect of the arc-shaped area B of the curved cover plate 30.
When the arc-shaped area Q of the elastic pressure head 11 and the arc-shaped surface b of the pressing piece 122The radius of curvature of the upper portions is unequal, the arcuate surfaces b of the pressing members 122Is smallest inThe radius of curvature R is smaller than the minimum radius of curvature R of the curved region of the elastic indenter 11.
In one embodiment, as shown in fig. 1b, the curved display screen attaching device further includes a push rod 131, and a first end of the push rod 131 is rigidly connected to the pressing member 12. The extension line of the axis of the push rod 131 passes through the first arc surface b1The arc apex of (a). In this way, the thrust exerted by the driving member 13 is exactly perpendicular to the first arc face b1Thereby further improving the attachment of the curved region B of the curved cover plate 30. Fig. 2 is a schematic structural view of a curved display screen attaching apparatus according to another embodiment of the present invention. As can be seen from comparing fig. 1a and 2, the curved display panel attaching apparatus further includes a force transmitter connected between the pressing member 12 and the driving member 13, compared to the curved display panel attaching apparatus 10. Specifically, the pressing member includes a first pressing member 121 and a second pressing member 122, the curved-surface display screen attaching device 40 further includes a rotating shaft 14, a first attaching arm 151 and a second attaching arm 152, a first end of the first attaching arm 151 is fixedly connected to the first pressing member 121, a first end of the second attaching arm 152 is fixedly connected to the second pressing member 122, and a second end of the first attaching arm 151 and a second end of the second attaching arm 152 are respectively rotatably connected to the rotating shaft 14. The first pressing element 121 and the second pressing element 122 may have the same structure or different structures, and are not limited specifically herein, and may be used to realize the function of attaching a curved display screen.
The curved-surface display screen attaching device further comprises a push rod 131, a first end of the push rod 131 is connected with the rotating shaft 14, and the axis of the push rod 131 is parallel to the rotating planes of the first attaching arm 151 and the second attaching arm 152; a pushing force is applied to the pressing member 12 through the push rod 131.
Specifically, as shown in fig. 2, in the curved display screen attaching device, when the push rod 131 pushes the rotating shaft 14 upward, the first end of the first attaching arm 151 and the first end of the second attaching arm 152 are driven to move upward, and meanwhile, by virtue of the elasticity of the elastic pressing head 11, the second end of the first attaching arm 151 drives the first pressing member 121 to move, and the second end of the second attaching arm 152 drives the second pressing member 122 to move; that is, the second end of the first attaching arm 151 drives the first pressing member 121 to move upward and leftward, and the second end of the second attaching arm 152 drives the second pressing member 122 to move upward and rightward.
According to the curved display screen attaching device provided by the embodiment, by arranging the force transmission piece, the direction of the thrust applied to the first pressing piece 121 and the second pressing piece 122 by the push rod 131 can be changed, so that the thrust direction just points to the first arc-shaped surface b1. Meanwhile, the curved display screen attaching device may further include a driving member 13, and the driving member 13 may be disposed at a more flexible position, for example, as shown in fig. 2, the driving member 13 is disposed on an attaching plane a with the elastic pressing head 111On the opposite side, the crossing of the different attachment arms within the elastic indenter 11 is avoided, compared to the curved display screen attachment device shown in fig. 1 b.
In one embodiment, first and second engaging arms 151 and 152 are symmetrical about pushrod 131. In this case, the first pressing member 121, the first attaching arm 151, the rotating shaft 14, the second attaching arm 152, the second pressing member 122, and the elastic pressing head 11 between the first pressing member 121 and the second pressing member 122 are sequentially connected to form an isosceles triangle, which has a more stable structure, more uniform acting force applied to the two pressing members, and a better attaching effect.
In one embodiment, the resilient ram 11 includes a cavity within which one or more of the push rod 131, the spindle 14, the first engaging arm 151, and the second engaging arm 152 are located. Because the push rod 131, the rotating shaft 14, the first attaching arm 151 and the second attaching arm 152 can generate a motion track in the elastic pressure head 11, by providing a cavity for accommodating these components, a pulling effect on the elastic pressure head 11 during the motion process can be avoided.
The shape and size of the cavity depend on the size of the corresponding component to be accommodated and its motion trajectory. In one embodiment, the smaller the cavity, the better, provided this requirement is met. This makes it possible to reduce as far as possible the influence on the structure of the elastic indenter itself.
In one embodiment, first and second engaging arms 151 and 152 are telescoping rods. Specifically, the first attaching arm 151 adopts a pneumatic telescopic structure, and includes a pneumatic cylinder, a piston rod, a first gas exchange valve, and a second gas exchange valve. The first gas exchange valve and the second gas exchange valve are respectively arranged on the pneumatic cylinder at a fixed distance from two ends of the pneumatic cylinder and used for controlling the extension and contraction of the piston rod, and the first pressing piece 121 is rigidly connected with the piston rod. Alternatively, the first attaching arm 151 is a ball screw, and a nut of the ball screw is rigidly connected to the first pressing member 121. The second attaching arm 152 has the same structure as the first attaching arm 151. It should be understood that the configurations of the first and second attaching arms 151 and 152 given herein are merely exemplary, and the present invention is not limited thereto.
According to the curved display screen attaching device provided by the embodiment, by arranging the first attaching arm 151 and the second attaching arm 152 to be telescopic, under the condition that the positions of the first attaching arm 151 and the second attaching arm 152 are not changed, the magnitude of the pushing force applied to the first pressing part 121 and the second pressing part 122 is adjustable.

A collar 42 is sleeved on the periphery of the middle section, and the inner diameter r of the collar 423Greater than the diameter r of the cross-sectional circle of the middle section2Outer diameter r of collar 424Smaller than the diameter r of the cross-sectional circle of the edge section1. In this way, it is possible to ensure that the collar 42 rotates freely about the presser body 41 without falling off.
According to the curved display screen attaching device provided by the embodiment, the second end of the attaching arm 151 can rotate around the pressing member 40, and compared with the rigid connection between the attaching arm and the pressing member, the pulling of the elastic pressing head 11 around the pressing member 40 during the movement of the attaching arm is avoided.

The application process of the curved surface display screen laminating device comprises the following steps: the collar 42 rotates around the cylindrical body 41 during the movement of the abutment arm 15 from the position of the broken line to the position of the solid line, by applying pressure to the shaft by means of the drive. When the second limit protrusion 52 contacts with the first limit protrusion 51, the collar 42 stops rotating, and at this time, the attaching arm 15 is just perpendicular to the first arc-shaped surface b1I.e. the thrust exerted by the driving member on the pressing member is directed exactly towards the first arc-shaped surface b1The arc vertex of the curved cover plate can reduce the probability of the defects of bubbles or black spots and the like in the arc area of the curved cover plate to the maximum extent.
