The driving component includes components fixed to the fixed plate 1. The cylinder 7 is located at the lower end of the fixed plate 1. The output end of the cylinder 7 passes through the fixed plate 1 and is installed at the lower end of the lifting plate 2. A connecting block 9 is fixedly installed on the upper side of the output end of the cylinder 7. Fixed blocks 10 are provided on both the left and right sides of the connecting block 9. An arc-shaped groove 11 is opened at one end of the fixed block 10. The fixed block 10 is fixed to the lower end of the lifting plate 2 by bolts. At the same time, the arc-shaped groove 11 fits against the lower end of the connecting block 9, fixing the output end of the cylinder 7 to the lower end of the lifting plate 2. When the cylinder 7 is started, it can drive the lifting plate 2 to move. The lifting plate 2 is located below the tray. When the cylinder 7 drives the lifting plate 2 to move upward, it lifts the tray.

[0020] A circular hole 23 is provided on the side wall of the lifting plate 2. A position sensor 8 is provided inside the circular hole 23. The lower end of the position sensor 8 passes through the circular hole 23 and is fixed to the outer wall of the cylinder 7. When the cylinder 7 drives the lifting plate 2 to move, the circular hole 23 moves outside the position sensor 8. A controller 12 is fixedly installed on one side of the lower end of the fixing plate 1. The controller 12 and the position sensor 8 are electrically connected. The position sensor 8 detects whether the cylinder 7 has been lifted to the correct position. If the cylinder 7 has not been lifted to the correct position, the position sensor 8 sends a signal to the controller 12. The controller 12 controls the cylinder 7 to continue lifting until it is lifted to the preset position.

[0021] Two ear plates 3 are fixedly installed at the diagonal of the lifting plate 2. A positioning rod 4 is fixedly installed at the upper end of the ear plate 3. Several support columns 5 are evenly fixedly installed at the upper end of the lifting plate 2. A positioning groove corresponding to the positioning rod 4 is set at the diagonal of the lower end of the pallet. The positioning rod 4 is inserted into the positioning groove to position the pallet, while the support column 5 supports the pallet.

[0022] A buffer component is provided between the fixed plate 1 and the lifting plate 2. The buffer component includes a thickened plate 13, a fixed cylinder 14 and a drive block 21. The thickened plate 13 and the fixed cylinder 14 are fixed to the lower side of the fixed plate 1. The thickened plate 13 is fixed to the lower end of the fixed plate 1 by bolts. A threaded rod 15 is fixedly installed on the upper end of the fixed cylinder 14. The upper end of the threaded rod 15 passes through the fixed plate 1. Two nuts 16 are threadedly connected to the outer end of the threaded rod 15. The two nuts 16 are located at the upper end of the fixed plate 1 and the lower end of the thickened plate 13, respectively, to fix the fixed cylinder 14 and the threaded rod 15.

[0023] A sliding column 18 is elastically connected inside the fixed cylinder 14. A buffer block 19 is fixedly installed at the lower end of the sliding column 18. A groove 17 is opened at the lower end of the threaded column 15. The end of the sliding column 18 away from the buffer block 19 is slidably inserted into the groove 17. A spring 20 is fixedly installed between the buffer block 19 and the threaded column 15. The spring 20 is sleeved on the outer end of the sliding column 18. The sliding column 18 slides in the groove 17 by compressing the spring 20. The driving block 21 is fixedly installed at the lower end of the guide shaft of the linear bearing 6. The driving block 21 is located directly below the buffer block 19. An impact block 22 is fixedly installed at the outer end of the driving block 21. The impact block 22 is located at the lower end of the buffer block 19. When the guide shaft of the linear bearing 6 moves, it will drive the driving block 21 and the impact block 22 to move, and make the impact block 22 contact the buffer block 19. The sliding column 18 slides in the groove 17 by compressing the spring 20, which plays a buffering role.

[0024] In actual use, when the pallet needs to be lifted, the drive cylinder 7 drives the lifting plate 2 to move upward. At the same time, when the guide shaft of the linear bearing 6 moves, it will drive the drive block 21 and the impact block 22 to move, and make the impact block 22 contact the buffer block 19. The slide column 18 slides in the slide groove 17 through the compression spring 20 until the lifting plate 2 lifts the pallet. At the same time, it plays a role in buffering the lifting force to prevent the pallet from tilting or falling off the production line.
