Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display processing, in particular to an auxiliary fixing device for finished product film pasting in the processing and production of liquid crystal displays. Background Technique

[0002] The processing of liquid crystal displays is a field involving multiple complex processes and technologies. First of all, the selection of raw materials is crucial. High-quality liquid crystal materials, glass substrates, and related electronic components are the basis for ensuring the quality of the display. During the processing, lithography technology is widely used. Through lithography, circuit patterns can be precisely formed on the substrate. For example, manufacturing a thin-film transistor array plays a key role in controlling the display effect of each pixel. The liquid crystal filling process also requires a high degree of precision to ensure that the liquid crystal is evenly distributed between the two substrates without bubbles and impurities mixed in. The assembly link cannot be ignored either. Good assembly can ensure the structural stability of the display. Finally, a protective film needs to be pasted on the surface of the liquid crystal screen to prevent the surface of the liquid crystal screen from being scratched.

[0003] After retrieval, in the prior art, Chinese Patent Publication No.: CN220350058U discloses an automatic film pasting device for liquid crystal displays. The utility model includes a frame and a clamping mechanism. An installation seat is installed on the inner bottom surface of the frame, and a positive and negative thread lead screw driving structure is arranged in the installation seat, and a clamping mechanism is installed on the positive and negative thread lead screw driving structure. A liquid crystal display is placed on the fixed seat. Screw driving structures are installed on both sides of the inner wall of the frame, and a bracket is arranged on the two screw driving structures. A branch pipe penetrates through the surface of the bracket, and one end of the branch pipe is communicated with a vacuum chuck. A vacuum pump is installed on the top surface of the frame. In this utility model, it can play a good buffering effect during the process of limiting and clamping the liquid crystal display, avoid the probability of the liquid crystal display being clamped and damaged, ensure the integrity of the liquid crystal display, and at the same time can ensure the stability during the film pasting process of the liquid crystal display, ensure that the liquid crystal display does not shake easily, and the film pasting effect is more ideal.

[0004] However, this device still has the following defects:

[0005] This device uses the elastic force of a spring to push the clamping plate against both sides of the liquid crystal screen, making it difficult to adjust the clamping mechanism. When pasting a film on a liquid crystal screen with a smaller size, there will be a situation of insufficient clamping force, and when pasting a film on a liquid crystal screen with a larger size, there will be a situation where the clamping force is too large and the liquid crystal screen is damaged. This device does not solve this problem. Content of the Utility Model

[0023] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0024] A finished product film pasting auxiliary fixing device for liquid crystal display screen processing and production, including a processing table. The processing table includes a box body 1, and two groups of mounting plates 2 are fixedly installed on both sides of the box body 1. It also includes a limiting component. The limiting component includes two groups of first limiting plates 3 and two groups of second limiting plates 4. A moving plate 5 is fixedly installed at the bottom of the first limiting plate 3, and a moving seat 6 is fixedly installed in the middle of the bottom of the moving plate 5. The moving seats 6 of the two moving plates 5 are respectively installed in two screw grooves with opposite directions on the surface of a bidirectional lead screw 7. Two groups of sliding seats 10 are fixedly installed on both sides of the bottom of the moving plate 5. The sliding seats 10 are slidably matched with sliding rods 11. The two ends of the sliding rods 11 are fixedly installed on the top surface of a lifting plate 9 through fixing seats 12. The two ends of the bidirectional lead screw 7 are rotatably installed on a mounting seat 13, and the mounting seat 13 is fixedly installed on the lifting plate 9. The bidirectional lead screw 7 is in transmission cooperation with the output end of a motor 14, and the motor 14 is fixedly installed on the mounting seat 13. By setting the bidirectional lead screw 7, the moving plate 5 can be driven to move through the moving seat 6, so that the two groups of first limiting plates 3 can be attached to both sides of liquid crystal display screen bodies 18 with different sizes, preventing the liquid crystal display screen bodies 18 from sliding longitudinally. The cooperation with the sliding seats 10 and the sliding rods 11 can improve the stability of the moving plate 5; the second limiting plate 4 is slidably matched with the mounting plate 2. One side of the second limiting plate 4 is fixedly connected to the telescopic end of a first air cylinder 8. Two groups of sliders 16 are fixedly installed on both sides of the bottom of the second limiting plate 4. A chute 17 is formed on the surface of the mounting plate 2, and the sliders 16 are slidably matched with the chute 17. The first air cylinder 8 is fixedly installed on the mounting plate 2. Rubber pads 19 are bonded to the sides of the first limiting plate 3 and the second limiting plate 4 that contact the liquid crystal display screen bodies 18. Anti-slip strips are arranged on the surfaces of the rubber pads 19. By setting the first air cylinder 8 to push the second limiting plate 4, the other two sides of the liquid crystal display screen bodies 18 can be limited, preventing the liquid crystal display screen bodies 18 from sliding horizontally. The cooperation with the first limiting plate 3 can limit the four sides of the liquid crystal display screen bodies 18, thereby fixing the horizontal position of the liquid crystal display screen bodies 18, preventing the liquid crystal display screen bodies 18 from sliding during the film pasting process, reducing the difficulty of film pasting. At the same time, the first limiting plate 3 and the second limiting plate 4 do not apply force to the liquid crystal display screen bodies 18, thereby avoiding damaging the liquid crystal display screen bodies 18.

[0025] It also includes a lifting component. The lifting component includes a lifting plate 9. The lifting plate 9 is slidably installed inside the box body 1. The bottom of the lifting plate 9 is fixedly connected to the telescopic end of a second air cylinder 15, and the second air cylinder 15 is fixedly installed on the bottom surface of the box body 1. By using the second air cylinder 15 in cooperation with the lifting plate 9, the liquid crystal display screen bodies 18 can be moved up and down, facilitating the taking and placing of the liquid crystal display screen bodies 18.

[0026] During specific use, move this device to the designated position, place the LCD screen body 18 on the surfaces of the two sets of moving plates 5, start the motor 14, control the positive rotation of the output end of the motor 14, the output end of the motor 14 drives the bidirectional lead screw 7 to rotate forward, so that the moving seats 6 installed in the two sets of reverse thread grooves drive the moving plates 5 and the first limiting plate 3 to move towards each other. When the rubber pad 19 on one side of the first limiting plate 3 contacts the side wall of the LCD screen body 18, turn off the motor 14, control the telescopic end of the second cylinder 15 to contract downward, drive the lifting plate 9 to move downward, so that the LCD screen body 18 moves downward. When the moving plate 5 moves to the bottom of the box body 1, at this time, both sides of the bottom of the LCD screen body 18 contact the surface of the mounting plate 2. Control the telescopic ends of the two sets of first cylinders 8 to extend, so as to push the second limiting plate 4 to start moving. When the rubber plate of the second limiting plate 4 just contacts the LCD screen body 18, turn off the first cylinder 8. At this time, the fixation of the LCD screen body 18 is completed, and the film can be pasted. After the film pasting is completed, control the first cylinder 8 to contract, control the second cylinder 15 to extend upward, and control the output end of the motor 14 to rotate reversely, then the limit on the LCD screen body 18 can be released and it can be lifted upward, which is convenient for the operator to take out the LCD screen body 18.
