[0002] During the laser welding process of the aluminum busbars, battery modules may experience cracking spots, weld penetrations, and cold joints. Modules with cold joints can be repaired by re-welding. However, modules with cracking spots or weld penetrations cannot be repaired online and must be disassembled into individual cells and reassembled into modules for reuse.

[0003] Currently, most of the module disassembly solutions disclosed in the industry use mechanical milling to separate the aluminum bars and battery cells in the module. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a battery module disassembly device, which includes a base, a clamping frame, a laser cutting machine and a movable frame, and the laser cutting machine is provided with a laser head.

The laser cutting machine is set on the mobile end of the X-axis mobile module, with the laser head pointing towards the clamping frame.

[0006] When in use, the battery module with exploded points or welded through is fixed on the clamping frame, and then the laser cutting machine is moved using the X-axis moving module and the Y-axis moving module to cut the aluminum row on the battery module along the preset trajectory, thereby disassembling the battery module into single battery cells for easy reuse.

[0007] Furthermore, it also includes a Z-axis moving module, the fixed end of the Z-axis moving module is set on the moving end of the X-axis moving module, and the laser cutting machine is set on the moving end of the Z-axis moving module, so that the laser cutting machine can also be moved in height, which is convenient for cutting different battery modules.

[0008] The X-axis, Y-axis, and Z-axis are the same as those in the industry, that is, the X-axis, Y-axis, and Z-axis are perpendicular to each other, the X-axis and Y-axis are in the horizontal direction, and the Z-axis is in the direction of gravity.

[0009] Furthermore, the laser cutting machine also includes a camera for identifying battery module images. In conjunction with a built-in or external image processing device, such as a computer, it can automatically identify aluminum bars and plan the movement route of the laser cutting machine, so that different battery modules can be directly cut.

[0010] Furthermore, the laser cutting machine also includes a gas nozzle for releasing nitrogen for cutting protection.

[0011] Furthermore, the clamping frame includes a supporting plate, a first clamping portion and a second clamping portion. The supporting plate is used to support the battery module, and the first clamping portion and the second clamping portion are used to clamp both ends of the battery module respectively.

[0012] Furthermore, the first clamping portion and the second clamping portion are provided with limiting blocks for limiting the two ends of the battery module, so that the battery module is clamped more reliably.

The clamping frame also includes a first rotating seat and a second rotating seat, the first clamping part is rotatably arranged on the first rotating seat, and the second clamping part is rotatably arranged on the second rotating seat. After the cutting of one side of the battery module is completed, the lifting module drives the support plate to descend, and then utilizes the cooperation of the two clamping parts and the rotating seat to directly rotate the battery module while clamping the battery module, so that the surface to be cut faces upward, and then the lifting module drives the support plate to rise to support the bottom side of the battery module, so that the battery module can be relatively fixed during cutting.

[0014] Furthermore, the clamping frame also includes a motor, and the first clamping portion is transmission-connected to the motor, and the motor drives the first clamping portion to rotate, so that the battery module can rotate automatically.

[0015] Furthermore, the clamping frame includes a locking nut, which is disposed on the second clamping portion at a position corresponding to the inner side of the second rotating seat. The second clamping portion is provided with corresponding threads. When the locking nut is tightened, the locking nut abuts the second rotating seat, thereby increasing the pressure of the second clamping portion on the battery module. When the locking nut is loosened, the second clamping portion can be moved, thereby facilitating the securing and removal of the battery module.

[0016] Furthermore, the first clamping portion and the second clamping portion are provided with positioning pins adapted to the positioning holes on the battery module, so that the two clamping portions can clamp the battery module more reliably.

[0017] Compared with traditional mechanical milling devices, the laser cutting method used in this utility model produces almost no aluminum metal debris during the cutting process, and also improves the efficiency of module disassembly, making it easier to disassemble the battery module into single cells for cascade utilization.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1 、 Figure 2 The battery module 6 disassembly device includes a base 1, a clamping frame 2, a laser cutting machine 3 and a movable frame 4, and the laser cutting machine 3 is provided with a laser head 5.

[0026] The clamping frame 2 is connected to the base 1 and is used to clamp and support the battery module 6. The movable frame 4 includes an X-axis movable module 7 and a Y-axis movable module 8. The fixed end of the Y-axis movable module 8 is fixed to the base 1, and the fixed end of the X-axis movable module 7 is set on the movable end of the Y-axis movable module 8. In order to adapt to more battery modules 6 of different specifications, this embodiment also includes a Z-axis movable module 9. The fixed end of the Z-axis movable module 9 is set on the movable end of the X-axis movable module 7. The laser cutting machine 3 is set on the movable end of the Z-axis movable module 9. The laser head 5 points to the clamping frame 2, so that the laser cutting machine 3 can also be moved in height to facilitate cutting different battery modules 6.

[0027] In this embodiment, the laser cutting machine 3 preferably further includes a camera 10 for identifying images of the battery modules 6. In conjunction with a built-in or external image processing device, such as a computer, the camera 10 can automatically identify the aluminum bars and plan the movement path of the laser cutting machine 3, enabling direct cutting of different battery modules 6. The laser cutting machine 3 also includes a gas nozzle 11 for spraying nitrogen gas for cutting protection during the laser cutting process.

[0028] The clamping frame 2 of this embodiment includes a support plate 12, a first clamping portion 13, and a second clamping portion 14. The support plate 12 is used to support the battery module 6, and the first clamping portion 13 and the second clamping portion 14 are respectively used to clamp the two ends of the battery module 6. The first clamping portion 13 and the second clamping portion 14 are provided with stoppers 15 for limiting the positions of the two ends of the battery module 6, thereby ensuring a more secure clamping of the battery module 6. The first clamping portion 13 and the second clamping portion 14 are provided with locating pins 16 that are adapted to the locating holes on the battery module 6, thereby ensuring a more secure clamping of the battery module 6 by the two clamping portions.

[0029] The clamping frame 2 also includes a lifting module 17, the fixed end of the lifting module 17 is fixedly connected to the base 1, and the support plate 12 is arranged on the movable end of the lifting module 17. The clamping frame 2 also includes a first rotating seat 18 and a second rotating seat 19, the first clamping part 13 is rotatably arranged on the first rotating seat 18, and the second clamping part 14 is rotatably arranged on the second rotating seat 19. After the cutting of one side of the battery module 6 is completed, the lifting module 17 drives the support plate 12 to descend, and then uses the cooperation of the two clamping parts and the rotating seat to directly rotate the battery module 6 while clamping the battery module 6, so that the surface to be cut faces upward, and then the lifting module 17 drives the support plate 12 to rise to support the bottom side of the battery module 6, so that the battery module 6 can be relatively fixed during cutting. The clamping frame 2 also includes a motor, and the first clamping part 13 is transmission-connected to the motor, and the motor drives the first clamping part 13 to rotate, so that the battery module 6 can rotate automatically.

[0030] The clamping frame 2 further includes a locking nut 20, which is disposed on the second clamping portion 14 at a position corresponding to the inner side of the second rotating seat 19, and the second clamping portion 14 is provided with a corresponding thread. Figure 3 、 Figure 4 When tightening the locking nut 20, the locking nut 20 abuts against the second rotating seat 19, thereby increasing the pressure of the second clamping portion 14 on the battery module 6; when loosening the locking nut 20, the second clamping portion 14 can be moved, thereby facilitating the fixing and removal of the battery module 6.

[0031] During use, the battery module 6 with a burst point or weld through is placed on the clamping frame 2, with the battery cell pole facing upward, and then the locking nut 20 is tightened to fix the battery module 6. The camera 10 is used to capture the image of the battery module 6, and a photo is taken to identify the center rivet hole of the pole of the battery cell in the battery module 6. After processing, the movement trajectory of the laser cutting machine 3 is generated. The laser cutting machine 3 is moved using the X-axis moving module 7, the Y-axis moving module 8, and the Z-axis moving module 9. The laser head 5 emits a laser to cut along the periphery of the weld on the pole of the battery module 6. During the cutting process, the gas nozzle 11 blows protective gas nitrogen for cutting protection. After cutting all the battery cell pole welds on the battery module 6, the module cover is removed, completing the first cut of the battery module 6.

[0032] The second time the weld seams remaining on the battery module 6's cell poles are cut, the support plate 12 first sinks under the drive of the lifting module 17. At this time, the battery module 6 is suspended in the air. The motor drives the battery module 6 to rotate 90°, so that the side of the battery module 6 faces upward. Then, the support plate 12 rises under the drive of the lifting module 17 to support the battery module 6, and the laser cutting machine 3 cuts off the excess weld seams on the battery module 6. Similarly, the support plate 12 sinks under the drive of the lifting module 17. At this time, the battery module 6 is suspended in the air. The motor drives the battery module 6 to rotate 180°, so that the other side of the battery module 6 faces upward. The support plate 12 rises under the drive of the lifting module 17 to support the battery module 6, and the laser cutting machine 3 cuts off the excess weld seams on the battery module 6.

[0033] After the welds on both sides of the module are cleaned, the support plate 12 is lowered by the lifting module 17. The battery module 6 is now suspended in the air, and the motor rotates the battery module 6 90°, so that the battery module 6 pole faces upward. The locking nut 20 is then loosened, and the second clamping portion 14 is withdrawn a certain distance. The battery module 6, with the pole welds now cleaned, is removed. Finally, a laser cleaning mechanism is used to clean the cell pole surface of the battery module 6, ensuring that the cell pole surface is clean and free of foreign matter.

[0034] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention.
