[0025] Embodiment 1: As shown in the accompanying drawings, a processing and positioning device for a liquid crystal display screen includes a bottom frame 1 and a workbench 2. The workbench 2 is fixedly connected to the top of the bottom frame 1. The device further includes a positioning and clamping assembly, which is used to position and clamp the liquid crystal display screen to be processed.

[0026] In this embodiment, specifically, the positioning and clamping assembly includes a fixed block 3, a bidirectional threaded rod 4, a plurality of moving blocks 5, a plurality of moving rods 6, a plurality of clamping blocks 7, a rubber pad 8, and a driving assembly. The fixed blocks 3 are symmetrically and fixedly connected to the side walls of the workbench 2. The bidirectional threaded rod 4 is rotatably connected to the adjacent fixed blocks 3. The plurality of moving blocks 5 are respectively threadedly connected to the adjacent bidirectional threaded rod 4. The plurality of moving rods 6 are respectively slidably connected to the adjacent moving blocks 5. The plurality of clamping blocks 7 are fixedly connected to the opposite sides of the moving rods 6. The clamping blocks 7 are L-shaped. The rubber pad 8 is adhesively connected to the inner wall of the clamping blocks 7. The driving assembly is used to drive the bidirectional threaded rod 4 when positioning the liquid crystal display screen. Among them, the driving assembly includes a motor 9, a transmission assembly 10, a push rod 11, and an adapter rod 12. The motor 9 is installed in the bottom frame 1. The transmission assembly 10 is installed between the output shaft of the bidirectional threaded rod 4 and the motor 9. The push rod 11 is slidably connected to the bottom of the workbench 2. The adapter rod 12 is slidably connected between two adjacent moving rods 6. The push rod 11 is fixedly connected to the adapter rod 12.

[0027] Further, it further includes a trigger component, which is used to trigger the motor 9 to start clamping the liquid crystal display screen after the liquid crystal display screen is placed. Wherein, the trigger component includes a pressing block 14, a first spring 15, a button 16 and a second spring 17. The pressing block 14 is slidably connected to the workbench 2. The first spring 15 is connected between the bottom of the pressing block 14 and the workbench 2. The button 16 is slidably connected inside the workbench 2. The button 16 is electrically connected to the motor 9. The second spring 17 is connected between the button 16 and the workbench 2. The top of the button 16 contacts the bottom of the pressing block 14. Further still, it further includes a locking component, which is used to lock the moving rod 6 after the clamping block 7 clamps the liquid crystal display screen. Wherein, the locking component includes a plurality of locking screws 18, a plurality of rubber blocks 19, a plurality of nuts 20, a plurality of gears 21 and a rack frame 22. The plurality of locking screws 18 are threadedly connected to the moving block 5. The plurality of rubber blocks 19 are respectively fixedly connected to the bottoms of the adjacent locking screws 18. The plurality of nuts 20 are rotatably connected to the tops of the adjacent moving blocks 5. The locking screw 18 is threadedly connected to the nut 20. The plurality of gears 21 are key-connected to the adjacent nuts 20. The rack frame 22 is symmetrically fixedly connected to the top of the bottom frame 1. The gear 21 moves in engagement with the rack frame 22.

[0028] It should be noted that the top of the nut 20 is conical, which can guide the waste residues generated during the processing to prevent the waste residues from entering the gap between the nut 20 and the locking screw 18 and affecting the locking effect of the locking screw 18.

[0029] It should be noted that guide rollers 13 are rotatably connected to the top of the workbench 2 and the top of the pressing block 14, and the guide rollers 13 are made of rubber, which can reduce the friction for the movement of the liquid crystal display screen to prevent the liquid crystal display screen from being damaged due to friction during the movement.

[0030] It should be noted that the guide roller 13 on the pressing block 14 is higher than the guide roller 13 on the top of the workbench 2.

[0031] In the above technical solution, when the liquid crystal display screen needs to be processed, first place the liquid crystal display screen on the top of the workbench 2; manually pull the push rod 11 outward, and then place the liquid crystal display screen on the top of the workbench 2 in contact with the guide roller 13. The liquid crystal display screen presses the pressing block 14, and the pressing block 14 moves downward to press the button 16. Both the first spring 15 and the second spring 17 are compressed. The button 16 controls the motor 9 to start, and at the same time controls the push rod 11 to drive the clamping block 7 and the rubber pad 8 to move, so that the rubber pad 8 contacts the liquid crystal display screen, thereby clamping the liquid crystal display screen. Subsequently, the output shaft of the motor 9 drives the transmission component 10 to drive the bidirectional threaded rod 4 to rotate, so that the moving block 5 drives the moving rod 6 to move inward, thereby driving the clamping block 7 to move closer to the middle. The moving block 5 drives the gear 21 to move. The gear 21 meshes with the rack 22, so that the gear 21 drives the locking screw 18 to move downward, thereby driving the rubber block 19 to move downward, and thus can press and lock the moving rod 6, thereby improving the clamping stability to prevent the liquid crystal display screen from shifting during subsequent processing. In this way, during the period when the liquid crystal display screen can be clamped, the liquid crystal display screen is in the centered position, which is convenient for subsequent processing of the liquid crystal display screen, and the operation is simple and convenient.

[0032] The above is only an illustration of the best embodiment of the present invention, but it should not be construed as a limitation of the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to change. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
