[0002] After producing the light guide plates, some manufacturers will place an isolation film between the two light guide plates to isolate and identify the existence of the two light guide plates. At the same time, a protective film will be pasted on one side of any light guide plate to protect the surface of the light guide plate from contamination, scratches or other damage, so as to ensure the optical performance and surface quality before the light guide plate is assembled to the display module.

[0003] In the existing automatic film tearing equipment for light guide plates, the loading method mostly adopts a robotic arm cooperating with a loading mechanism to load the light guide plates.

[0049] To achieve the above purpose, Figure 1 and Figure 5 As shown, the cache lifting mechanism 100 proposed by the utility model includes:

[0050] The machine platform is provided with a mounting cavity and a feeding port 10a connected to the mounting cavity;

[0051] A cache mechanism 10, which is disposed in the installation cavity. The cache mechanism 10 includes a translation module 11 and a first bracket 12 disposed in the installation cavity. The first bracket 12 is slidably connected to the translation module 11, and the first bracket 12 can move on the translation module 11; and

[0052] The feeding mechanism 13 includes a lifting module 14 and a second supporting arm 15 arranged in the installation cavity. The lifting module 14 is located at one end of the translation module 11. The second supporting arm 15 is slidably connected to the lifting module 14. The second supporting arm 15 can move on the lifting module 14.

[0053] The cache lifting mechanism 100 has an initial feeding state and a material transfer state. In the initial feeding state, the position height of the second support arm 15 is lower than the position height of the first support arm 12; in the material transfer state, the light guide plate on the first support arm 12 moves to the top of the second support arm 15 through the translation module 11, and the second support arm 15 passes through the first support arm 12 through the lifting module 14 to transfer the light guide plate to the feeding port 10a.

[0054] In the technical solution of the utility model, the machine platform of the cache lifting mechanism 100 forms an installation cavity and a feeding port 10a connected to the installation cavity. The cache mechanism 10 and the feeding mechanism 13 are both arranged in the installation cavity. The stacked light guide plate materials can be placed on the first support arm 12 and the second support arm 15. When it is necessary to load the light guide plate tearing machine, the staff first places the first pile of light guide plate materials on the first support arm 12, and then moves it to the feeding mechanism 13 through the translation module 11. At this time, the second support arm 15 is above the first support arm 12, and then the lifting module 14 is started, the second support arm 15 rises, and the first pile of light guide plate materials is placed on the first support arm 12. The light guide plate material is transferred to the second support arm 15 to the feeding port 10a; after the material conversion is completed, the first support arm 12 returns to the original material change position, carries out the second loading and moves to a position close to the feeding mechanism 13. At this time, the first pile of light guide plate materials is temporarily in the feeding state. After the feeding of the first pile of light guide plate materials is completed, the height of the second support arm 15 drops to the bottom of the first support arm 12, and the first support arm 12 moves to the top of the second support arm 15 for feeding. Therefore, when facing multiple light guide plate tearing machines equipped with a cache lifting mechanism 100, the configuration of feeding personnel can be reduced, thereby reducing labor costs.

[0055] In this embodiment, the machine can be used as a separate basic frame to fix the cache mechanism 10 and the feeding mechanism 13, and can also be a part of the fixed frame 200 of the light guide plate tearing machine; the machine encloses an installation cavity that can accommodate the cache mechanism 10 and the feeding mechanism 13 and a feeding port 10a connected to the installation cavity. The term "feeding port 10a" can refer to the end point of the light guide plate material on the second support arm 15, or it can be the starting point of the tearing process of the light guide plate tearing machine, and is not limited here; when the light guide plate tearing machine needs to be loaded, the position of the machine corresponding to the first support arm 12 is opened to place the light guide plate material.

[0056] The cache mechanism 10 is fixedly arranged in the installation cavity. The cache mechanism 10 includes a translation module 11 and a first bracket 12. In this embodiment, in order to save the occupied area of ​​the cache lifting mechanism 100, the translation module 11 is arranged close to the machine platform. The first bracket 12 that can move along the translation module 11 is arranged on the translation module 11. The first bracket 12 includes two spaced fork arm structures. The translation module 11 includes a frame structure, moving parts, a transmission system, etc., wherein the frame structure is usually made of aluminum alloy material, has sufficient strength and rigidity to support the cache mechanism 10, and provides a fixing and support for the moving parts. Structural basis; the moving part can be a guide rail structure or a linear guide rail structure or a slider structure for the movement of the first support arm 12, which is a part or workpiece used to support and guide the movement of the first support arm 12, and is not limited here; the transmission system can be a drive motor or a cylinder drive, which is not limited here. In this embodiment, the motor drive method is preferred. The translation drive motor 101 is controlled by the control system of the light guide plate tearing machine composed of a PLC, a touch screen and a host computer, and parameters are set to control the time and position of the feeding and retreating of the first support arm 12, so as to realize subsequent automatic feeding.

[0057] The feeding mechanism 13 includes a lifting module 14 and a second support arm 15 arranged in the installation cavity. In order to save the occupied area of ​​the cache lifting mechanism 100, the feeding mechanism 13 is located at one end of the translation module 11. At the same time, there is a space between the lifting module 14 and the cache mechanism 10 for the first support arm 12 and the second support arm 15 to move. The lifting module 14 includes a mounting frame, a lifting drive motor 131 arranged on the mounting frame and capable of driving the second support arm 15, and a guide rail arranged on the mounting frame. The lifting drive motor 131 of the feeding mechanism 13 is controlled by the control system of the light guide plate tearing machine. The second support arm 15 includes two spaced fork arm structures. The second support arm 15 is controlled by the lifting drive motor 131 to move up and down on the guide rail. Furthermore, the spacing distance between the two fork arm structures of the second support arm 15 is greater than the spacing distance between the two fork arm structures of the first support arm 12, so that when material conversion is performed, the second support arm 15 is on the outside of the first support arm 12, so that the two force-bearing positions carrying the light guide plate material are equally spaced, thereby improving the stability of the material on the second support arm 15 when it rises.

[0058] When the cache lifting mechanism 100 is feeding, it is in an initial feeding state at the beginning. In the initial feeding state, the position height of the second support arm 15 is lower than the position height of the first support arm 12, so that when the material is converted, the light guide plate material can be transferred from the first support arm 12 to the second support arm 15; subsequently entering the material transfer state, the second support arm 15 rises under the drive of the lifting drive motor 131 to drive the light guide plate material to the feeding port 10a, and when the material is fed, the first support arm 12 can retreat to the starting position, carry out the second loading and move on the translation module 11 to a position close to the feeding mechanism 13 to wait for the second support arm 15 to drop to the lowest point, and quickly carry out the second feeding.

[0059] In one embodiment of the present invention, Figure 1 As shown, a translation guide rail 111 is provided on the translation module 11, and a movable gap 16a is formed between the translation guide rail 111 and the translation module 11; the first support arm 12 includes a connecting portion 17 and a fork arm group 18, the fork arm group 18 is connected to the connecting portion 17, and the connecting portion 17 can be inserted into the movable gap 16a.

[0060] In this embodiment, a translation guide rail 111 is provided on the translation module 11, and a movable gap 16a is formed between the translation guide rail 111 and the translation module 11; the first support arm 12 includes a connecting portion 17 and a fork arm group 18 detachably connected to the connecting portion 17, the fork arm group 18 is composed of two parallel fork arms, and the fork arms can be installed on the connecting portion 17 by screwing or by snapping, so as to achieve the replacement of damaged fork arms; the connecting portion 17 can be inserted in the movable gap 16a, and the movement on the translation guide rail 111 is achieved through the control of the translation drive motor 101.

[0061] The utility model also provides a light guide plate automatic film tearing device 1000, such as Figures 2 to 9 As shown, the automatic light guide plate film tearing equipment 1000 includes a fixed frame 200, a cache lifting mechanism 100, a mold taking mechanism 300 and a film tearing mechanism 400; the machine is connected to the fixed frame 200, the mold taking mechanism 300 is movably arranged on the fixed frame 200, and the mold taking mechanism 300 is provided with a first vacuum suction cup 33 and a clamping part 36, the first vacuum suction cup 33 is used to adsorb the light guide plate located at the feed port 10a, and the clamping part 36 can clamp the isolation film located on the back of the light guide plate; the film tearing mechanism 400 includes a film tearing robot movably arranged on the fixed frame 200 to tear off the protective film on the front side of the light guide plate.

[0062] In the present embodiment, the automatic film-tearing device 1000 for light guide plates comprises a fixed frame 200 and a cache lifting mechanism 100, a mold-taking mechanism 300 and a film-tearing mechanism 400 arranged on the fixed frame 200. The light guide plates are fed by the cache lifting mechanism 100, the mold-taking mechanism 300 takes away the isolation film, and the film-tearing mechanism 400 tears off the protective film, thereby realizing a fully automated film-tearing process. Among them, the feed port 10a of the cache lifting mechanism 100 is located on the fixed frame 200, and is also the starting position of the process of taking away the isolation film. First of all, it needs to be explained that the front side of the light guide plate located at the top layer is a protective film attached to the surface of the light guide plate, and the back side is an isolation film without adhesion, and the isolation film is located between the two light guide plates for distinguishing and isolating. When the light guide plate reaches the feed port 10a, it first passes through the first true film of the mold-taking mechanism 300. The empty suction cup 33 takes away the top layer of the light guide plate, and the film-tearing robot of the film-tearing mechanism 400 tears off the protective film on the front side. At this time, the isolation film is completely exposed on the surface of the second layer of the light guide plate. Then the clamping part 36 clamps the isolation film and moves it to the waste collection area 200a provided on the fixed frame 200, and the protective film on the film-tearing robot is also collected in the waste collection area 200a; the automatic light guide plate film-tearing equipment 1000 has a control system composed of a PLC, a touch screen and a host computer. Under the control of the control system, the loading process and the film-tearing process cooperate with each other to improve the working efficiency of the automatic light guide plate film-tearing equipment 1000; at the same time, an isolation cover composed of multiple pieces of glass is also provided on the fixed frame 200 to prevent dust from appearing on the surface of the light guide plate during the operation of the automatic light guide plate film-tearing equipment 1000.

[0063] In one embodiment of the present invention, Figure 2 , Figure 6 as well as Figure 7 As shown, the mold taking mechanism 300 includes:

[0064] A light guide plate transfer mechanism 31, the light guide plate transfer mechanism 31 comprises a first transfer module 32 disposed on the fixed frame 200 and a first vacuum suction cup 33 movably disposed on the first transfer module 32; and

[0065] The isolation film clamping mechanism 34 includes a second transfer module 35 disposed on the fixed frame 200 and a clamping portion 36 movably disposed on the second transfer module 35 , and the clamping portion 36 can clamp the isolation film.

[0066] In the present embodiment, the mold taking mechanism 300 includes a light guide plate transfer mechanism 31 and an isolation film clamping mechanism 34; the light guide plate transfer mechanism 31 includes a first transfer module 32 and a first vacuum suction cup 33 movably arranged on the first transfer module 32, the first transfer module 32 includes a guide rail, a servo motor and a connecting arm, the guide rail is fixed on one side of the fixed frame 200, one end of the connecting arm is connected to the guide rail, and the other end is connected to the first vacuum suction cup 33, the servo motor drives the connecting arm to move on the guide rail under the control of the control system, the connecting arm is connected to at least one first vacuum suction cup 33, when there is only one first vacuum suction cup 33, the adsorption point of the first vacuum suction cup 33 on the light guide plate is at the center of the light guide plate to prevent the first vacuum suction cup 33 from being unstable when transferring the light guide plate, causing the light guide plate to fall; when the connecting arm is connected to multiple first vacuum suction cups 33, the first vacuum suction cup 33 is connected to the light guide plate, and the light guide plate is not stable when the first vacuum suction cup 33 is transferred. Suction cup 33, any two first vacuum suction cups 33 are arranged at intervals to increase the adsorption area of ​​the light guide plate and improve the stability when transferring the light guide plate; after the light guide plate on the top layer is adsorbed away, the isolation film clamping mechanism 34 starts to work, the isolation film clamping mechanism 34 includes a second transfer module 35 arranged on the fixed frame 200 and a clamping part 36 movably arranged on the second transfer module 35, the second transfer module 35 includes a guide rail, a servo motor and a connecting arm, the second transfer module 35 is fixed on one side of the fixed frame 200 adjacent to the first transfer module 32, the movement direction of the first vacuum suction cup 33 is perpendicular to the movement direction of the clamping part 36, the space utilization rate of the fixed frame 200 is improved, and the occupied area is saved; the clamping part 36 is connected to the connecting arm, and the opening and closing size of the clamping part 36 can be realized under the control of the servo motor, so as to clamp and release the isolation film.

[0067] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the mold taking mechanism 300 also includes a film fixing component, which includes a material distribution structure and a film fixing structure 37 movably arranged on the periphery of the feed port 10a; the material distribution structure and the film fixing structure 37 can both approach or move away from the light guide plate synchronously, the material distribution structure can abut the light guide plate, and the film fixing structure 37 can clamp and fix the isolation film.

[0068] In this embodiment, the mold removal mechanism 300 also includes a film fixing component, which includes a material distribution structure and a film fixing structure 37 movably arranged on the periphery of the feed port 10a. It needs to be explained that because the isolation film has no adhesion, when the light guide plate transfer mechanism 31 removes a light guide plate, the isolation film on the back has the problem of moving with the light guide plate. Therefore, when a light guide plate is removed, the film fixing structure 37 on the periphery of the feed port 10a will move closer to each other through a servo motor or other driving parts to clamp and fix the isolation film. After a light guide plate is removed, the film fixing structure 37 moves away from each other to release. The isolation film is then clamped by the clamping portion 36 to the waste collection area 200a. It can be understood that the fixed film structure 37 can be set to a long rod shape or a multi-segment structure, which is not limited here; further, in order to prevent multiple light guide plates from shifting in position during the discharge process, both ends of the fixed film structure 37 are provided with a material balancing structure, which is connected to the fixed film structure 37 to achieve synchronous approaching or moving away from the light guide plate with the fixed film structure 37. The material balancing structure can abut against multiple light guide plates at one time to fine-tune the position of the light guide plate at the feed port 10a, thereby improving the subsequent film tearing accuracy.
