[0002] With the rapid development of new energy vehicles and energy storage industries, the large-scale application of lithium-ion batteries has led to a surge in the number of waste battery packs. Battery packs are usually composed of multiple battery modules connected in series or in parallel, and have high recycling value. Their efficient disassembly and resource recycling are of great significance to reducing environmental pollution and realizing a circular economy.

[0003] However, the existing disassembly process mostly relies on manual labor, and has problems such as low efficiency, high safety risks, and low recycling yield. In addition, the battery pack shell packaging forms are diverse and the internal connection structure is complex. The existing equipment generally has poor adaptability and is difficult to be compatible with the disassembly needs of battery packs of multiple specifications.

[0057] Brief description of the working process of the present invention:

[0058] The incoming battery pack is manually hoisted and placed into the Pack trolley mechanism 2 using the KBK hoist. After completion, the trolley is pushed into the jacking and positioning mechanism 1 below the lifting and flipping mechanism 3. The jacking cylinders 13 on both sides of the jacking and positioning mechanism 1 extend to push the jacking wedges 14. The inclined surfaces of the jacking wedges 14 cooperate with the jacking rollers 15 to drive the lifting frame 12 to rise and lift the pallet 23 of the Pack trolley 21. The lifting drive module 34 of the lifting and flipping mechanism 3 rotates, so that the flip base 35 together with the rotating fork clamp 36 descends to the upper surface of the battery pack 26, and the four Pack fixing plates 37 are manually locked with the mounting points of the battery pack 26. The lifting drive module 34 rotates, driving the flip base 35, the rotating fork clamp 36 and the battery pack 26 to rise together. After rising to a safe height, the rotating fork clamp 36 rotates 180 degrees, and then the lifting drive module 34 rotates, driving the flip base 35, the rotating fork clamp 36 and the battery pack 26 to fall back to the Pack trolley 21. Manually remove the connecting bolts between the four Pack fixing plates 37 and the battery pack 26. The lifting and positioning mechanism 1 is lowered to release the Pack trolley 21, and the Pack trolley 21 is pulled out to complete the flipping of the battery pack 26 so that the bottom plate faces upward, which is convenient for subsequent operations.

[0059] The trolley is manually pushed into the lifting and positioning mechanism 1 below the bottom plate milling mechanism 4. The lifting cylinders 13 on both sides of the lifting and positioning mechanism 1 extend to push the lifting wedges 14. The inclined surfaces of the lifting wedges 14 cooperate with the lifting rollers 15 to drive the lifting frame 12 to rise and lift the tray 23 of the Pack trolley 21. The visual system 48 of the bottom plate milling mechanism 4 takes pictures of the three mark points of the battery pack 26 for positioning, and then the bottom plate milling mechanism 4 drives the 3D line scan camera on the visual system 48 to scan the upper surface of the battery pack 26 to obtain the flatness of the milling path. The bottom plate milling mechanism 4 compensates for the milling height according to the correction position and flatness data fed back by the visual system 48, and automatically mills the upper bottom plate of the battery pack 26 and the surrounding areas where the box body is bolted. During the milling process, the dust removal fan is turned on, and the milling debris is drawn away through the dust removal hood 49 and the connecting pipeline. After the milling is completed, the lifting and positioning mechanism 1 is lowered to release the Pack trolley 21, and the Pack trolley 21 is pulled out to complete the milling of the bottom plate of the battery pack 26, so that the connection between the bottom plate and the box body is disconnected.

[0060] The head of the battery pack 26 that has been manually pried and milled is tilted up at one corner, and the trolley is pushed into the lifting and positioning mechanism 1 below the stripping and extruding mechanism 5. The lifting cylinders 13 on both sides of the lifting and positioning mechanism 1 extend to push the lifting wedges 14. The inclined surfaces of the lifting wedges 14 cooperate with the lifting rollers 15 to drive the lifting frame 12 to rise and lift the tray 23 of the pack trolley 21. The stripping mechanism (lifting mechanism 52, rotary drive mechanism 53 and stripping roller 54) on the stripping and extruding mechanism 5 inserts the stripping roller 54 into the tilted edge of the head of the battery pack 26. The rotary drive mechanism 53 rotates, driving the stripping roller 54, and at the same time, the bottom plate of the battery pack 26 is wound up and separated from the box body. After winding is completed, the modules in the battery pack are exposed. At this time, the transfer drive mechanism 59 is activated, and the extrusion tooling 58 is moved to the top of the single module. The press on the press head 57 descends, driving the extrusion tooling 58 to press down, so that the module is separated from the battery pack body, and the module falls into the tray 23 of the pack cart 21. Repeat several times to press out all the modules in the battery pack 26. After the extrusion is completed, the lifting and positioning mechanism 1 descends to release the pack cart 21, and the pack cart 21 is pulled out, and the entire battery pack disassembly and module recovery process is completed.

[0061] The protective fence mechanism 6 independently separates the lifting and flipping mechanism 3, the bottom plate milling mechanism 4 and the stripping and extruding mechanism 5, so that the equipment at each station does not affect each other when it is running or stops abnormally, ensuring the equipment operation efficiency and personnel safety. Personnel can observe or operate the equipment at the operation box outside the protective fence mechanism 6.

[0062] In addition, for different product changes, the spacing between the forks on the rotating fork clamp 36 of the lifting and flipping mechanism 3 and the position of the Pack fixing plate 37 on the fork are adjusted to be compatible with the flipping of battery packs of different lengths and widths. The bottom plate milling mechanism 4 presets different product milling recipes, and can be switched to be compatible with different products with one click through the program. The working range of the stripping and extrusion mechanism 5 can cover the largest product. When changing the model, the extrusion tooling 58 can be replaced to adapt to different size modules, and different product production can be achieved by switching the program recipe.

[0063] The present invention designs a device for disassembling the battery pack and recycling the modules in the whole process. The battery pack bottom plate disassembly and module removal are realized through the Pack trolley mechanism, the lifting and flipping unit, the bottom plate milling unit and the stripping and extruding unit, etc., and it has a relatively large flexible and compatible production function, which meets the needs of diversified products in the recycling industry and has great practical value. The connection between the bottom plate and the box body is mainly cut by the bottom plate milling mechanism, which only destroys the bottom plate and does not damage the battery pack box body. The battery pack box body can be recycled at the same time, which has a relatively large economic value. After the module is exposed, the inner module is automatically pressed out through the stripping and extruding mechanism, which is efficient, safe, and has good integrity of the inner module, and the recycling yield is greatly improved. The disassembly method of the present invention has no chemical harm to the environment and human body, meets the industrialization requirements of green recycling, and has a relatively high social and economic value.

[0064] The present invention designs a device composed of battery pack flipping, back milling, bottom plate stripping and module extrusion devices, which realizes battery pack flipping, bottom plate milling, bottom plate stripping and module extrusion, greatly improves disassembly efficiency, reduces manual work, greatly improves the degree of equipment automation, and is compatible with a variety of battery pack production.
