Description

Technical Field

[0001] The utility model relates to the disassembly of waste batteries, in particular to a waste battery module disassembly system. Background Art

[0002] As the power source for new energy vehicles, battery packs consist of components such as the outer casing and the battery modules installed within. Each battery module consists of several battery cells encapsulated together. With the rapid development of new energy vehicles, new energy vehicle power batteries are about to be retired on a large scale. Most of these used battery packs are due to partial cell failure, rendering the entire battery pack unusable. Therefore, the classified recycling and reuse of the battery cells within the battery pack is of great significance, which places higher requirements on the meticulous disassembly of the battery pack.

[0003] The recycling process for used battery packs involves first removing the cover from the battery pack casing to obtain the battery module, and then disassembling the battery module to obtain the battery cells. Currently, battery module disassembly is primarily manual, resulting in low efficiency and inability to rapidly disassemble large quantities of used battery packs. Furthermore, electrolyte leakage is prone to occur during the disassembly process, resulting in poor working conditions in the workshop. Therefore, designing a mechanized system for disassembling used battery modules is crucial. Summary of the Invention

The disassembled battery core can be removed by using the material retrieving robot 7 and the gripper mechanism 8.

[0029] Two six-axis robots are spaced apart on the stage 2, with a cutting mechanism 3 and a cutting and milling mechanism 4 installed on one of the six-axis robots. The cutting mechanism 3 has an ultrasonic cutting blade, and the cutting and milling mechanism 4 has a milling cutter.

[0030] The upper conveying unit 5 and the lower conveying unit 6 are arranged parallel to each other on the frame 1, and the upper conveying unit 5 passes through the loading platform 2.

The first clamping assembly includes a fixed clamping block 10b spaced apart on the fixed base plate 10a and a movable clamping block 10c driven by a first linear power source.

[0031] The left and right sides of the frame 1 are provided with a lifting platform 12 (preferably a guide rail chain lifting platform) connected to the upper conveying unit 5 and the lower conveying unit 6. The lifting platform 12 is a single-layer (or double-layer) lifting platform. The lifting platform 12 can transfer the supporting assembly 10 fixed with the battery module to the upper conveying unit 5, and can also transfer the empty supporting assembly 10 to the battery pack disassembly process to realize the assembly line disassembly of the battery module;

[0032] There are multiple leakage holes on the loading platform 2, and the liquid collecting structure includes a liquid collecting cover 2a arranged under the loading platform 2. The liquid collecting cover 2a is a conical structure with a larger top and a smaller bottom. The bottom of the liquid collecting cover 2a is connected to the waste liquid barrel 2b through a drain pipe; during the disassembly process, the electrolyte flows from the leakage holes to the liquid collecting cover 2a, and finally enters the waste liquid barrel 2b (to facilitate subsequent centralized treatment), thereby avoiding electrolyte leakage, effectively ensuring the workshop working environment and reducing environmental pollution; an exhaust hood 14 and a fan 15 connected to the exhaust hood are provided on the top of the protective cover 13.

The fixed base plate 10a is also equipped with a guide block 10e that cooperates with the piston rod of the bidirectional cylinder 10d to prevent the movable clamping block 10c from twisting. During operation, the piston rod of the bidirectional cylinder 10d drives the movable clamping block 10c toward the fixed clamping block 10b to achieve clamping. The bidirectional cylinder 10d then drives the movable clamping block 10c away from the fixed clamping block 10b to achieve opening, thereby meeting the clamping and securing requirements of the battery module. Each piston rod of the bidirectional cylinder 10d is equipped with a return spring 10f to facilitate the return of the movable clamping block 10c.

[0034] Combine Figure 3-4It can be seen that the gripping mechanism 8 includes a fixed plate 8a, a second linear power source and a second clamping assembly. A mounting frame 8j is provided on one side of the fixed plate 8a, and the second linear power source is a second cylinder 8c arranged in the mounting frame 8j; the second clamping assembly includes a fixed splint 8d fixed on the other side of the fixed plate 8a and a movable splint 8e driven by the second cylinder 8c; two groups of guide sleeves 8b are arranged at intervals on the fixed plate 8a, and two guide shafts 8f arranged at intervals are provided on the movable splint 8e, and the guide shafts 8f pass through the corresponding guide sleeves 8b, thereby ensuring the linear movement of the movable splint 8e; the gripping mechanism 8 also includes an anti-slip structure, the anti-slip structure includes a third cylinder 8g hinged to the bottom of the back side of the movable splint 8e and an anti-slip frame 8h hinged to the upper part of the back side of the movable splint 8e, the middle part of the anti-slip frame 8h is hinged to the third cylinder 8g, and the anti-slip frame 8h has a plurality of anti-slip teeth 8i arranged at intervals, which effectively ensure the clamping and fixing effect and prevent it from falling.

[0035] Combine Figure 2 It can be seen that an XYZ three-axis drive mechanism 11 (a commercially available XYZ high-precision mobile platform) is provided on the top plate of the protective cover 13. The XYZ three-axis drive mechanism 11 has a lifting seat, on which the screw screwing mechanism 9 is provided. The XYZ three-axis drive mechanism 11 is used to adjust the horizontal and height positions of the screw screwing mechanism 9. Figure 1 As can be seen, the upper conveyor unit 5 and the lower conveyor unit 6 are mounted on the frame 1. The upper conveyor unit 5 includes an upper conveyor belt (which can be a conveyor chain) that drives the support assembly 10. The frame 1 is provided with an upper guide member (i.e., an upper guide rail) that guides the support assembly 10. The support assembly 11 slides with the upper guide rail. The lower conveyor unit 6 includes a lower conveyor belt (which can be a conveyor chain) that drives the support assembly 10. The frame 1 is also provided with a lower guide member (lower guide rail) that guides the support assembly 10. In actual operation, the upper conveyor unit 5 transports the battery module to the loading platform 2 for disassembly. After disassembly is completed, the lower conveyor unit 6 transports it to the next process, laying the foundation for the assembly line disassembly of the battery pack.

[0036] The working process and principle of the present invention are briefly described as follows: the battery module to be disassembled is moved from the previous process to the lifting platform 12 on the left side, the lifting platform 12 is raised to the same height as the upper conveying unit 5, so that the supporting assembly 10 equipped with the battery module is transferred to the upper conveying unit 5, and the upper conveying unit 5 is used to move the supporting assembly 10 to the loading platform 2; then the visual system is used to identify the position of the battery module, and when it moves to the cutting station, the cutting milling mechanism 4 is used to mill and remove the welding points of the battery module, and the screw tightening mechanism 9 is used to remove the screws on the battery module, and the battery module is used to remove the screws. The cutting mechanism 3 cuts the battery module, thereby realizing the disassembly of the battery module; after the disassembly is completed, the disassembled battery module on the loading platform 2 is removed by the material-picking robot and the gripper mechanism 8 and placed on the next process; during this process, the supporting assembly 10 continues to move to the right, and is transferred to the lower conveying unit 6 below through the transfer lifting device on the right. The lower conveying unit 6 drives the empty supporting assembly 10 to move to the left, and enters the previous process through the transfer lifting device on the left to support the battery module to be disassembled. This cycle realizes the assembly line disassembly operation of the battery module and improves work efficiency.
