[0020] The pressing mechanism includes an electric telescopic rod 8, a mounting cavity 9, a mounting seat 10, a pressing roller 11 and a transmission assembly. The electric telescopic rod 8 is installed on both sides of the bottom end of the mounting plate 5. The bottom end of the electric telescopic rod 8 is installed with a mounting cavity 9. A transmission assembly is arranged inside the mounting cavity 9. A mounting seat 10 is installed at one end of the transmission assembly. A pressing roller 11 is rotatably installed inside the mounting seat 10. The transmission assembly includes a servo motor 12, a rotating sleeve 13, a threaded block 14, a transmission rod 15 and a limiting structure. The servo motor 12 is installed at one end of the mounting cavity 9. A rotating sleeve 13 is installed inside the mounting cavity 9. The output end of the servo motor 12 is connected to one end of the rotating sleeve 13. A threaded block 14 is arranged inside the rotating sleeve 13. A transmission rod 15 is installed at one end of the threaded block 14. One end of is connected with one side of the mounting base 10. When in use, when the touch screen contacts the liquid crystal display screen, the electric telescopic rod 8 is started to drive the mounting cavity 9 to move downward, so that the pressing roller 11 contacts the screen with each other. At this time, the servo motor 12 is started, and the rotating sleeve 13 is driven to rotate under the limit of the limit groove 16 and the limit block 17. Since the rotating sleeve 13 is threadedly connected with the threaded block 14, the threaded block 14 is driven to move. Then, under the limit of the positioning block 18 and the positioning groove 19, the transmission rod 15 is driven to move by the threaded block 14, and then the pressing roller 11 is driven to move. The pressing roller 11 is moved from the middle to both sides of the touch screen to perform a pressing process on it, so that the bonding effect between the liquid crystal display screen and the touch screen is better, and bubbles are not easy to be generated during bonding, thereby greatly improving the practicality of the device when in use.

[0021] The limiting structure includes a limiting groove 16, a limiting block 17, a positioning block 18 and a positioning groove 19. The limiting groove 16 is opened on the outer wall of the rotating sleeve 13, and the limiting block 17 is arranged inside the limiting groove 16. The limiting block 17 is installed inside the mounting cavity 9. The positioning groove 19 is opened on both sides of the transmission rod 15. The positioning block 18 is arranged inside the positioning groove 19. The positioning block 18 is installed on both sides of one end inside the mounting cavity 9. The cross section of the positioning block 18 is smaller than the cross section of the positioning groove 19. A sliding structure is formed between the positioning block 18 and the positioning groove 19. When in use, the limiting groove 16 and the limiting block 17 cooperate with each other to limit the rotating sleeve 13 when it rotates, so that the rotating sleeve 13 is more stable when it rotates. The positioning block 18 and the positioning groove 19 cooperate with each other to limit the transmission rod 15 when it moves, so that the transmission rod 15 is more stable when it moves.

[0022] The positioning mechanism includes a side plate 20, a threaded groove 21, a threaded rod 22, a limit plate 23, a rotating wheel 24 and a guide structure. The side plate 20 is respectively mounted on both sides of the mounting plate 5 and one end of the support plate 6. The inside of the side plate 20 is provided with a threaded groove 21, and the inside of the threaded groove 21 is penetrated by a threaded rod 22. One end of the threaded rod 22 is mounted with a rotating wheel 24, and the other end of the threaded rod 22 is mounted with a limit plate 23. The threaded rod 22 and the limit plate 23 are rotatably connected. When in use, the rotating wheel 24 drives the threaded rod 22 to rotate. Since the threaded groove 21 and the threaded rod 22 are threadedly connected, the threaded rod 22 moves inside the threaded groove 21. Then, under the limitation of the limiting hole 25 and the limiting rod 26, the threaded rod 22 is used to drive the limit plate 23 to move. The staff adjusts the limit plate 23 to an appropriate position according to the actual situation, so that the LCD screen is more accurate when fitting, thereby greatly improving the versatility of the device when in use.

[0023] The guide structure includes a limiting hole 25 and a limiting rod 26. The limiting hole 25 is opened below the side plate 20. The limiting rod 26 is arranged inside the limiting hole 25. One end of the limiting rod 26 is connected to one end of the limiting plate 23. When in use, the limiting hole 25 and the limiting rod 26 cooperate with each other to limit the limiting plate 23 when moving, so that the limiting plate 23 is more stable when moving.

[0024] Working principle: the staff first rotates the rotating wheel 24 to drive the threaded rod 22 to rotate. Since the thread groove 21 and the threaded rod 22 are threadedly connected, the threaded rod 22 moves inside the thread groove 21, and then the threaded rod 22 drives the limit plate 23 to move under the limit of the limit hole 25 and the limit rod 26. The staff adjusts the limit plate 23 to an appropriate position according to the actual situation, and then places the LCD screen on the top of the support plate 6, limits it with the limit plate 23, and fixes it with the pneumatic suction cup 7. The touch screen is placed on the bottom of the mounting plate 5, and is fixed with the pneumatic suction cup 7. Then the cylinder 4 is started to drive the mounting plate 5 and the touch screen. The touch screen moves downward. When the touch screen contacts the liquid crystal display screen, the electric telescopic rod 8 is started to drive the installation cavity 9 to move downward, so that the lamination roller 11 contacts the screen. At this time, the servo motor 12 is started to drive the rotating sleeve 13 to rotate under the limit of the limit groove 16 and the limit block 17. Since the rotating sleeve 13 is threadedly connected with the threaded block 14, the threaded block 14 is driven to move. Then, under the limit of the positioning block 18 and the positioning groove 19, the transmission rod 15 is driven to move by the threaded block 14, and then the lamination roller 11 is driven to move. The lamination roller 11 is moved from the middle of the touch screen to both sides to perform a lamination process on it, so that it is not easy to have bubbles when the touch screen and the liquid crystal display screen are fitted.
