[0041] Referring to Figure 3 and Figure 4 , the circumferential direction of the collecting cover 51 is provided with a rotating hole 512, the rotating hole 512 dividing the collecting cover 51 into two parts, the upper and lower parts of the collecting cover 51 being connected to each other through a rotating ring 533 in the embodiment, in other embodiments, the upper and lower parts of the collecting cover 51 being fixedly connected through a plurality of connecting rods, improving the stability of the collecting cover 51, the top surface and the bottom surface of the rotating ring 533 being respectively rotatably connected to the inner wall of the rotating hole 512, and the inner diameter of the rotating ring 533 being located in the inside of the collecting cover 51.

[0042] The upper part of the collecting cover 51 prolongs the cover height of the collecting cover 51, and improves the safety degree of the application. The central assembly 53 comprises a central motor 531 fixedly connected to the collecting cover 51, a driving gear 532 fixedly connected to the central motor 531, a rotating ring 533 rotatably connected to the collecting cover 51, and a cleaning brush 534 fixedly connected to the rotating ring 533. The central motor 531 and the driving gear 532 are located outside the collecting cover 51. The output end of the central motor 531 is fixedly connected to the center of the driving gear 532. The axis of the rotating ring 533 coincides with the axis of the rotating hole 512. The top surface and the bottom surface of the rotating ring 533 are rotatably connected to the inner wall of the rotating hole 512, respectively. The rotating hole 512 limits the movement of the rotating ring 533, so that the rotation of the rotating ring 533 is more stable.

The driving gear 532 and the external gear ring 5331 are meshed with each other. When the user starts the central motor 531, the central motor 531 drives the driving gear 532 to rotate. Due to the meshing relationship between the driving gear 532 and the external gear of the rotating ring 533, the rotating ring 533 rotates.

[0043] Further, the inner diameter of the rotating ring 533 is located inside the collecting cover 51. One end of the cleaning brush 534 is fixedly connected to the inner diameter of the rotating ring 533. The rotating ring 533 drives the cleaning brush 534 to rotate after rotating. The cleaning brush 534 is located inside the collecting cover 51. The end of the cleaning brush 534 away from the rotating ring 533 extends to the center of the movable hole 11. The end of the cleaning brush 534 away from the rotating ring 533 is close to the edge of the movable hole 11. The bottom of the cleaning brush 534 contacts the top surface of the base 1.

It is convenient for the user to send the materials from the collecting bin 511 into the inside of the collecting box 52, and improves the cleaning efficiency.

[0044] When the user starts the cylinder 2 to lift the movable plate 4, the central motor 531 is started to adjust the position of the cleaning brush 534, reducing the interference of the cleaning brush 534 to the shell pulling work. When the user pushes the materials inside the lithium battery shell out, the fixed chain 31 is released to constrain the lithium battery shell, and the lithium battery shell is taken out. After the central motor 531 is started, the driving gear 532 drives the rotating ring 533 and the cleaning brush 534 to rotate. The bottom of the cleaning brush 534 is a flexible brush. The cleaning brush 534 sweeps from the top surface of the base 1 and the fixed chain 31. After the materials are gathered at the position of the collecting bin 511, the user sweeps the materials into the inside of the collecting bin 511. Since the collecting bin 511 is downwardly inclined, the materials enter the inside of the collecting box 52 along the collecting bin 511, realizing the cleaning and collecting of the materials, and improving the efficiency of the user in disassembling the lithium battery shell.
