During use, the battery cell 3 is first placed in the debonding agent in the immersion part 2 for soaking, so as to debond the adhesive between the battery cell 3 and the plastic bracket and reduce the difficulty of subsequent separation. The battery cell 3 is then placed in the disassembly part 1, and the lower bracket of the battery cell is clamped by the clamping piece 11. The upper bracket of the battery cell 3 is then clamped and lifted upward by the lifting piece 12, so as to separate the upper bracket of the battery cell 3 from the battery cell body 311, thereby achieving a gentle separation effect. Finally, the battery cell body 311 is lifted up in the clamping position of the clamping piece 11 on the lower bracket, and separated from the lower bracket. The entire separation process can realize non-destructive disassembly of the battery cell, greatly improve the disassembly yield and efficiency of the battery cell 3, and provide a strong guarantee for the high-value cascade utilization of the battery cell 3.

[0033] Understandably, see Figure 3 The battery cell 3 is composed of a battery cell body 311, a plastic upper bracket 312 glued to the top of the battery cell body 311, and a plastic lower bracket 313 glued to the bottom of the battery cell body 311.

When the battery cell 3 is flush with the disassembly plane of the disassembly part 1, the conveying member 22 is used to push it from the lifting member 23 to the disassembly plane of the disassembly part 1 for subsequent disassembly, thereby achieving the process of immersion and transportation of the battery cell 3.

[0035] Specifically, the positioning member 11 includes a workbench 111 and an extension platform 112. A pair of the extension platforms 112 are fixed on the top of the workbench 111 and are relatively distributed. The extension platform 112 is in an inverted L-shape and consists of a bottom block and a flat plate. The bottom block is fixed on the workbench 111, and the extension platform 112 is fixed on the top of the bottom block, and is used to press against the top of both sides of the lower bracket of the battery cell, wherein the flat plate presses against the top of the plastic lower bracket 313 to limit it.

[0036] Further, the lifting member 12 includes a cylinder push rod 121, an extension rod 122, a guide rod 123, a lifting frame 124 and a fixing seat 125. The cylinder push rod 121 is arranged on one side of the workbench 111. There are two lifting members 12, which are respectively located on the left and right sides of the workbench 111. The cylinder push rod 121 is also fixedly installed on the left and right sides of the workbench 111. The extension rod 122 is arranged at the telescopic end of the cylinder push rod 121. The extension rod 122 is a straight rod, which mainly serves to extend the push rod. The fixing seat 125 is arranged on the outside of the cylinder push rod 121. The guide rod 123 is arranged on the fixed seat 125, and the guide rod 123 is slidably connected with the lifting frame 124. The guide rod 123 is mainly used for guiding the lifting frame 124 when it is extended and retracted, so as to improve the stability of its up and down movement. The lifting frame 124 is arranged on the top of the extension rod 122, and the other side of the lifting frame 124 is used to clamp on the bottom of the upper bracket of the battery cell. The lifting frame 124 is mainly composed of a frame body connected with the extension rod 122 and a lifting plate clamped on the bottom of the upper bracket of the battery cell, and the lifting plate is a flat plate.

[0037] It can be understood that the battery cell 3 is inserted into the disassembly part 1, the plastic lower bracket 313 is inserted into the bottom side of the extension platform 112 for limiting, the plastic upper bracket 312 is pressed against the top of the lifting plate on the lifting frame 124, and the cylinder push rod 121 is extended upward to pull the lifting plate up, thereby separating the plastic upper bracket 312 from the battery cell body 311.

[0038] In this embodiment, in order to achieve stable pushing of the battery cells, the conveying member 22 includes a conveyor belt 221, and a plurality of ribs 222 are arranged at equal intervals on the conveyor belt 221 for pushing the battery cells in grids. The ribs 222 are arranged on the surface of the belt body of the conveyor belt 221 to divide the belt body into grid pushing intervals. A battery cell 3 can be placed in each pushing interval.

[0039] Furthermore, the pushing member 23 includes a first telescopic member 231, a connecting frame 232 and a pushing seat 233. The first telescopic member 231 is arranged on the outside of the immersion pool 21. There are two first telescopic members 231, which are respectively installed on the left and right sides of the immersion pool 21. The connecting frame 232 is arranged at the telescopic end of the first telescopic member 231. The connecting frame 232 is fixed between the top ends of the two first telescopic members 231. The pushing seat 233 is arranged at the bottom of the connecting frame 232. The pushing seat 233 is U-shaped, and its two sides are used to limit the left and right sides of the battery cell 3.
