The cutting blades 31 are all vertically oriented toward the upper surface of the lifting platform 21. When separating and disassembling the battery module to obtain the battery cells, the spacing between adjacent cutting blades 31 is first adjusted to make the spacing the same as the thickness of the battery cells. Then the battery module is placed on the lifting platform 21, and the telescopic cylinder 22 is started to lift the lifting platform 21 upward. Under the action of the thrust of the telescopic cylinder 22, the cutting blade 31 on the blade holder 14 can cut into the gaps between the battery cells, thereby separating the battery module into a plurality of battery cells. The battery module can be disassembled using the disassembly equipment, and the battery module can be disassembled in one operation. Compared with the traditional manual disassembly method, the disassembly efficiency is higher. Moreover, the disassembly equipment uses the telescopic cylinder 22 to lift the battery module, so that the battery module gradually approaches the cutting blade 31 on the blade holder 14. The relative motion trajectory between the battery module and the cutting blade 31 is a straight line, which avoids the cutting blade 31 from damaging the battery cell, ensures the recyclable value of the battery cell, and effectively prevents the battery cell from being damaged, damaging the health of the disassembly personnel, and polluting the environment.

[0027] In order to facilitate the dismantling personnel to place the battery module on the lifting platform 21 in the box body 1, see Figure 3The lifting platform 21 includes a support frame 23 and a sliding plate 24. The lower surface of the support frame 23 is vertically fixedly connected to the telescopic cylinder 22, and the upper surface is slidably connected to the sliding plate 24. The sliding plate 24 can slide along the length direction of the support frame 23. An inlet 16 is provided on one side of the shell 12. The width of the inlet 16 is not less than the width of the sliding plate 24, so that the sliding plate 24 can slide out of the inlet 16. After the dismantling personnel place the battery module on the sliding plate 24, they can push the sliding plate 24 carrying the battery module into the box body 1.

[0028] Furthermore, in order to facilitate the dismantling personnel to operate the sliding plate 24, a grip groove 25 is provided at one end of the lower surface of the sliding plate 24 near the insertion port 16, and the depth of the grip groove 25 is 1.5-3 cm. The provision of the grip groove 25 can facilitate the dismantling personnel to pull the sliding plate 24 out of the box body 1 or push it into the box body 1.

[0029] Furthermore, in order to prevent the dismantling personnel or unrelated personnel from inserting their hands or debris into the insertion opening 16 during the dismantling operation, see Figure 1 and Figure 2 A rotatably connected protective door 17 is provided on the outer side of the insertion port 16, and the area of ​​the protective door 17 is not less than the area of ​​the insertion port 16. After the dismantling personnel slide the sliding plate 24 with the battery module placed into the box body 1, the protective door 17 can be closed to prevent the personnel from mistakenly putting their hands or other objects into the box body 1 when the lifting platform 21 is lifted, thereby preventing the personnel from being injured by the equipment and preventing the internal structure of the dismantling equipment from being damaged.

[0030] Furthermore, in the process of disassembling the battery module, the disassembling equipment may generate debris, which may fly out of the inlet 16 and injure personnel or damage surrounding equipment. To prevent this from happening, the lower end of the protective door 17 is rotatably connected to the outer surface of the shell 12 through a hinge, and a locking buckle 18 is provided above the inlet 16. The locking buckle 18 is rotatably connected to the outer surface of the shell 12, and an unlocking notch 19 is provided on the side of the locking buckle 18 facing the edge of the protective door 17. The shape of the unlocking notch 19 is consistent with the edge of the protective door 17. The shape of the edge is matched, the distance between the inner surface of the locking buckle 18 and the outer surface of the shell 12 is matched with the thickness of the protective door 17. When the arc-shaped side of the locking buckle 18 faces downward, the upper end of the protective door 17 can be stuck between the inner side of the locking buckle 18 and the outer side of the shell 12, thereby locking the state of the protective door 17 and preventing the debris generated by disassembly from flying out of the inlet 16. When unlocking, the locking buckle 18 is rotated to align the unlocking notch 19 of the locking buckle 18 with the edge of the protective door 17, and the protective door 17 can be pulled outward to open.

[0031] Furthermore, in order to facilitate the dismantling personnel to operate the protective door 17 , an operating handle 171 is provided on a side surface of the protective door 17 away from the insertion port 16 .

The inner side of the lower frame 143 is vertically connected to the two ends of the cutting knife 31. The two ends of the cutting knife 31 are provided with fixing heads 32. The inner side of the lower frame 143 is provided with fixing grooves 144 at the positions where the two ends of the cutting knife 31 are in contact. The fixing heads 32 at the two ends of the cutting knife 31 can be embedded in the corresponding fixing grooves 144. After the upper frame 142 is fixed to the lower frame 143, the position of the cutting knife 31 on the knife holder 14 can be fixed.

[0033] Furthermore, the shape of the fixing groove 144 includes a U-shape, the lower end of the fixing groove 144 is closed, and the upper end is connected to the upper surface of the lower frame 143, and the shape of the fixing groove 144 matches the shape of the fixing head 32, so that the fixing heads 32 at both ends of the cutting knife 31 can be inserted into the fixing groove 144 from top to bottom.

[0034] As a preferred embodiment, in order to facilitate the dismantling personnel to observe the dismantling process of the battery module in the box body 1, see Figure 1 and Figure 2 An observation window 121 is provided at the top of the shell 12 , and the observation window 121 is covered with a protective plate 122 . The protective plate 122 is made of a transparent acrylic plate. The protective plate 122 made of a transparent acrylic plate can facilitate the dismantling personnel to observe the dismantling situation in the box body 1 through the observation window 121 .

[0035] Preferably, the telescopic cylinder 22 adopts an electric telescopic cylinder 22. The electric telescopic cylinder 22 is small in size and can provide greater thrust than the hydraulic telescopic cylinder 22 of the same size, and does not need to be connected to a hydraulic oil pump, so that the telescopic cylinder 22 can be extended or shortened, thereby driving the lifting platform 21 to rise or fall. When the lifting platform 21 rises, the battery module placed on the lifting platform 21 gradually approaches the cutting knife 31 on the tool holder 14 under the hydraulic thrust of the telescopic cylinder 22, and the cutting knife 31 can cut between the battery cells, thereby decomposing the battery module into several battery cells.
