[0058] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0059] Combine the following Figure 1-Figure 4 , describing the battery disassembly tooling provided in an embodiment of the present application.

[0060] The battery disassembly tool includes a base 100, a limiting mechanism, an elastic component 300 and a cutting mechanism 400. The base 100 is formed with a disassembly platform 110, and the disassembly platform 110 is used to place the battery to be disassembled; the limiting mechanism is arranged on the base 100, and is used to limit the battery 700 to be disassembled on the disassembly platform 110; the elastic component 300 is arranged on the limiting mechanism, and the elastic component 300 abuts against the outer surface of the battery to be disassembled by stretching along a preset direction; the cutting mechanism 400 is arranged on the base 100, and is used to cut the shell of the battery to be disassembled. It should be noted that the battery to be disassembled is a square shell battery, and the outer surface of the battery to be disassembled is six planes: up, down, left, right, front and back. The preset direction refers to the direction perpendicular to any one of the six planes, and the elastic component 300 abuts perpendicularly against the outer surface of the battery to be disassembled by stretching along the preset direction.

[0061] By utilizing the technical solution provided by the above-mentioned embodiment of the present application, a limiting mechanism and a cutting mechanism 400 are arranged on the base 100, and the elastic component 300 is arranged on the limiting mechanism. The elastic component 300 abuts against the outer surface of the battery to be disassembled by stretching and contracting along a preset direction. By utilizing the elastic force of the elastic component 300, it is possible to adapt to the uneven outer surface of the battery to be disassembled (the uneven outer surface of the battery caused by battery bulging and the like), so that while the outer surface of the battery to be disassembled is pressed tightly, excessive abutment between the local outer surface of the battery to be disassembled and the limiting mechanism can be prevented, thereby preventing the internal pole group of the battery to be disassembled from being damaged due to local stress concentration caused by excessive abutment during the limiting process of the battery to be disassembled. This is beneficial to protecting the internal pole group, avoiding the influence of secondary damage on the disassembly analysis results caused by secondary damage, and can also adapt to the dimensional tolerance of the battery to be disassembled.

[0062] Reference Figure 1 , Figure 2As shown, in some embodiments provided by the present application, the limiting mechanism includes a transverse limiting assembly 210 and a longitudinal limiting assembly 220, wherein the transverse limiting assembly 210 is used to abut against the outer surface of the battery to be disassembled along a first direction, the first direction being the length direction of the base 100; the longitudinal limiting assembly 220 is used to abut against the outer surface of the battery to be disassembled along a second direction, the second direction being the width direction of the base 100; and the elastic assembly 300 is disposed on at least one of the transverse limiting assembly 210 and the longitudinal limiting assembly 220. By arranging the transverse limiting assembly 210 and the longitudinal limiting assembly 220 on the base 100, the battery to be disassembled can be limited in the length direction and the width direction of the base 100 respectively, so that the battery to be disassembled can be more stably limited on the platform 110 to be disassembled, and the battery to be disassembled can be prevented from shifting during the cutting process of the battery to be disassembled by the cutting mechanism 400.

[0063] Reference Figure 1 , Figure 2As shown, in some embodiments provided in the present application, the lateral limit assembly 210 includes a first limit block 211 and a second limit block 212, and the first limit block 211 is fixedly mounted on the base 100; the second limit block 212 is movably mounted on the base 100, the second limit block 212 is arranged opposite to the first limit block 211, and the second limit block 212 can approach or move away from the first limit block 211 along the first direction, and the elastic assembly 300 is arranged on the side of the second limit block 212 close to the first limit block 211; the longitudinal limit assembly 220 includes a third limit block 221 and a fourth limit block 222, the third limit block 221 is movably mounted on the base 100; the fourth limit block 222 is movably mounted on the base 100, the fourth limit block 222 is arranged opposite to the third limit block 221, and the fourth limit block 222 and the third limit block 221 can approach or move away from each other along the second direction. By setting the second limiting block 212 and the first limiting block 211 opposite to each other, the two end faces of the battery to be disassembled are limited; by setting the fourth limiting block 222 and the third limiting block 221 opposite to each other, the two side faces of the battery to be disassembled are limited; by setting the elastic component 300 on the second limiting block 212, on the one hand, one end face of the battery to be disassembled can be elastically pressed to avoid damaging the internal electrode group; on the other hand, the position adjustment speed of the battery to be disassembled can be improved; specifically, when the battery to be disassembled is placed on the disassembly platform 110, the battery to be disassembled is tilted by an external force. The elastic component 300 is then pressed against one end face of the battery to be disassembled, and then the elastic component 300 is squeezed to place the battery to be disassembled between the second limit block 212 and the first limit block 211, so that the second limit block 212 is no longer needed to be moved. The elastic force of the elastic component 300 can be used to limit the freedom of the battery to be disassembled in the first direction, and then the third limit block 221 and the fourth limit block 222 are moved to limit the freedom of the battery to be disassembled in the second direction, thereby effectively shortening the positioning time of the battery to be disassembled on the disassembly platform 110 and improving the disassembly efficiency.

[0064] Reference Figure 1 , Figure 2As shown, in some embodiments provided by the present application, the elastic component 300 includes an abutment plate 310, a guide rod 320 and a buffer spring 330.

Specifically, the buffer spring 330 is in two groups. When the abutment plate 310 and the battery to be disassembled are pressed against each other, the buffer spring 330 is compressed and contracts along the guide rod 320; when the abutment plate 310 is separated from the battery to be disassembled, the buffer spring 330 is reset along the guide rod 320.

The length directions of the second through hole 630 and the second limit hole 640 are parallel to the width direction of the base 100. The second bolt passes through the second through hole 630 and the second limit hole 640 in sequence to install the third limit block 221 and the fourth limit block 222 on the base 100. At least one of the second through hole 630 and the second limit hole 640 is a bar hole; in this way, the third limit block 221 and the fourth limit block 222 can respectively move along the second limit hole 640, so as to adjust the distance between the third limit block 221 and the fourth limit block 222 to limit the battery to be disassembled.
