The threaded sleeve 6 is slidably connected to the partition 11, and a display screen 12 is attached to the clamping plate 7. The threaded rods 5 on both sides of the outer shell 2 are rotated to drive the threaded sleeve 6 to push the clamping plate 7 to clamp the display screen 12, thereby preventing the display screen 12 from shaking when the pre-laminating machine performs pressure detection on the display screen 12, thereby affecting the detected pressure data, thereby further improving the accuracy of pressure detection of the pre-laminating machine.

The output end of the electric push rod 14 is fixedly connected to the second telescopic rod 15. The end of the second telescopic rod 15 away from the electric push rod 14 is fixedly connected to the connecting rod 16. A driven shaft 17 is rotatably connected to the connecting rod 16. A pressure roller 20 is fixedly connected to the driven shaft 17. One end of the driven shaft 17 is fixedly connected to a gear 18. A rack 19 is fixedly connected to the shell 2. The gear 18 is meshed and connected to the rack 19. The end of the driven shaft 17 away from the gear 18 rolls on the shell 2. A pressure sensor 24 is fixedly connected to the placement plate 10. The model of the pressure sensor 24 is AXCX. The pressure sensor 24 is located on the same horizontal plane as the display screen 12. By arranging the pressure sensor 24 on the placement plate 10, the display screen 12 can be laminated in the pre-laminating machine. When the film is being laminated, the pressing roller 20 will squeeze the pressure sensor 24 at the same time, so that the pressure sensor 24 measures the pressure of the pre-laminator. At the same time, the height of the display screen 12 can be adjusted by the micro hydraulic rod 8, so that the force of the pressing roller 20 squeezing the display screen 12 is different, so that the pressure sensor 24 measures the maximum bearing capacity of the display screen 12 on the pre-laminator. Therefore, through such a setting, it can be avoided that the display screen 12 is damaged when the subsequent pre-laminator laminates the film on the display screen 12, thereby increasing the production cost. A slide groove 21 is provided on the placement plate 10, and a slider 22 is slidably connected to the slide groove 21. The end of the slider 22 away from the slide groove 21 is fixedly connected to the threaded sleeve 6. The bottom of the support plate 1 is fixedly connected to a support leg 23.

[0030] Working principle: first, place the display screen 12 on the placement plate 10, then align the protective film and place it on the display screen 12, then rotate the handles 4 on both sides of the shell 2, the rotation of the handles 4 drives the driving shaft 3 to rotate, the rotation of the driving shaft 3 drives the threaded rod 5 to rotate, the rotation of the threaded rod 5 drives the threaded sleeve 6 to move forward, the forward movement of the threaded sleeve 6 drives the slider 22 to slide on the slide groove 21, and at the same time, the threaded sleeve 6 pushes the clamping plate 7 to move forward to clamp the display screen 12, and then start the micro hydraulic rod 8, the output end of the micro hydraulic rod 8 drives the first telescopic rod 9 to extend, the first telescopic rod 9 extends to drive the placement plate 10 to rise, the placement plate 10 rises and drives the display screen 12 to rise and contact the surface of the pressure roller 20, and then stops rising, and at the same time the pressure sensor 24 also fits with the pressure roller 20, and then start the electric push rod 14, the output end of the electric push rod 14 drives the second telescopic rod 15 to extend and retract, and the extension of the second telescopic rod 15 drives the driven shaft 1 through the connecting rod 16 7 moves back and forth, and the driven rotating shaft 17 moves back and forth, driving the gear 18 to move on the rack 19, thereby causing the gear 18 to rotate. The rotation of the gear 18 drives the pressure roller 20 to rotate, and the rotation of the pressure roller 20 squeezes the protective film on the display screen 12, making it fit more closely with the display screen 12. At the same time, the pressure roller 20 rolls and squeezes the pressure sensor 24. The pressure sensor 24 feeds back the tested pressure data to the control system for analysis by the staff, and at the same time starts the micro hydraulic rod 8. The output end of the micro hydraulic rod 8 drives the first telescopic rod 9 to extend and retract. The extension of the first telescopic rod 9 drives the placement plate 10 to rise. The rise of the first telescopic rod 9 drives the display screen 12 to rise, thereby making the force of the pressure roller 20 squeezing the display screen 12 different. The pressure sensor 24 measures the maximum bearing pressure of the display screen 12 on the pre-laminating machine. Therefore, through such a setting, it is possible to avoid damage to the display screen 12 due to excessive pressure when the subsequent pre-laminating machine laminates the display screen 12.
