[0033] A sliding adjustment component is arranged on the inner wall of the slide groove 17;

[0034] The step protection assembly is arranged on the outer wall of the moving rod 8 .

[0035] Reference Figure 1 , Figure 2 and Figure 3The sliding adjustment component includes a fixed plate 5 fixedly connected to the inner wall of the material box 1, and the fixed plate 5 is rotatably connected to the driving plate 6. The inner wall of the fixed plate 5 is provided with symmetrically distributed slide grooves 17. The inner wall of the slide groove 17 is slidably connected with a slide plate 18, and the slide plate 18 is fixedly connected to the moving rod 8. The driving plate 6 rotates to drive the arc groove 7 to rotate, and the moving rod 8 is squeezed by the arc groove 7 to slide in the slide groove 17 through the slide plate 18, thereby driving the limit column 13 to move synchronously.

[0036] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7 The step protection assembly includes a limit column 13 fixedly connected to the outer wall of the moving rod 8, the inner wall of the limit column 13 is provided with a uniformly distributed fan-shaped groove 19, the inner wall of the fan-shaped groove 19 is rotatably connected with a step plate 20, the outer wall of the step plate 20 is fixedly connected with a guide plate 22, the inner wall of the fan-shaped groove 19 is slidably connected with a slide bar 21, and the outer wall of the slide bar 21 is sleeved with a return spring 24. The guide plate 22 will be squeezed during the movement of the display, and the guide plate 22 is made of an arc-shaped soft material to avoid damage to the display. At the same time, the display can better push the step plate 20 through the arc structure. The step plate 20 rotates in the fan-shaped groove 19 and finally rotates to the inner wall of the fan-shaped groove 19. At this time, the step plate 20 squeezes the slide bar 21 and the return spring 24. At this time, the return spring 24 is deformed and elastically stores energy. When the step plate 20 loses the squeezing force of the display, the return spring 24 releases the elastic energy and pushes the step plate 20 to rotate through the slide bar 21. At this time, the step plate 20 tilts and returns to its original position through the action of gravity, and is limited by the inner wall of the fan-shaped groove 19.

[0039] Reference Figure 2 The inner wall of the fixed plate 5 is fixedly connected with an electric push rod 12, and the electric push rod 12 is rotatably connected with the driving plate 6. The output end of the electric push rod 12 is fixedly connected with a lifting plate 16, and the lifting plate 16 is driven by the output end of the electric push rod 12 to push the display upward.

[0040] Specifically, when the automatic loading device for display screen production is working / in use: first, the display is put in through the feed plate 23, and the display is supported by the rubber support column 14. At the same time, the strong elastic effect of the strong spring 15 prevents the display from falling too quickly and being damaged. Then, the electric push rod 12 is started, and the lifting plate 16 is driven by the output end of the electric push rod 12 to push the display upward. During the movement of the display, the guide plate 22 will be squeezed, and the guide plate 22 is made of an arc-shaped soft material to avoid damage to the display. At the same time, the display can better push the step plate 20 to rotate in the fan-shaped groove 19 through the arc structure, and finally rotate to the inner wall of the fan-shaped groove 19. At this time, the step plate 20 squeezes the slide bar 21 and the return spring 24. At this time, the return spring 24 is deformed and elastic energy is stored. When the step plate 20 loses the squeezing force of the display, the return spring 24 releases the elastic energy and pushes the step plate 20 to rotate through the slide bar 21. At this time, the angle of the step plate 20 is tilted and It returns to its original position through the action of gravity and is limited by the inner wall of the fan-shaped groove 19. Similarly, when the display moves to the uppermost step plate 20, the output end of the electric push rod 12 contracts, and the display is placed on the step plate 20 at this time. This process is repeated until the display fills the step plate 20. Then, the driving structure (not shown in the figure) in the lifting and rotating box 2 is used to rotate and lift the loading rack 3, and the display is adsorbed, lifted and rotated to the processing position by adsorbing the loading plate 4. If it is necessary to adjust the limit column 13 to adapt to the size of the display, the drive motor 9 can be started to drive the drive gear 10 to rotate, and then the meshing transmission driven gear 11 can be rotated, thereby driving the drive plate 6 to rotate, that is, driving the arc groove 7 to rotate, and the moving rod 8 is squeezed through the arc groove 7 to slide in the slide groove 17 through the slide plate 18, thereby driving the limit column 13 to move synchronously, so as to adjust the distance between the limit columns 13 to adapt to displays of different sizes.
