[0001] This invention relates to the field of battery pack disassembly technology, and in particular to a device and method for disassembling and repairing battery packs for new energy vehicles. Background Technology

[0002] Currently, during the disassembly and repair of battery pack cells, the cells are typically coated with adhesive materials, including thermally conductive gel layers and insulating layers, used to fix the cells, conduct heat, and provide insulation protection. Therefore, when repairing faulty cells, these adhesive materials must first be removed. Existing disassembly operations mostly rely on manual peeling, which is cumbersome and inefficient. To solve this problem, existing technologies use robotic arms to drive blades to cut and tear the adhesive materials on the outside of the cells, achieving automated disassembly, replacing manual operation, and significantly improving disassembly efficiency.

[0003] In the aforementioned prior art, the method of cutting and peeling off the external adhesive material of the battery cell by blade is difficult to control precisely in actual operation.

Then, the buffer adjustment unit adjusts the rebound resistance of the cross-shaped cutting tool, ensuring that the resistance can penetrate the adhesive material but not scratch the battery cell casing. When the cross-shaped cutting tool penetrates the adhesive material and contacts the battery cell casing, the buffer adjustment unit buffers the impact, allowing the... The cross-shaped cutting blade is retracted by pushing; after the adhesive material of the battery cell is cut off, the cutting lateral movement component moves, and the shovel blade shovels the cut adhesive material to remove it from the battery cell, thus completing the peeling off of the adhesive material. Therefore, through the rotation of the cutting rotating chamber and the movement of the cutting lateral movement component, the path is stable during the cutting of adhesive material, preventing shaking and deviation. Simultaneously, the rebound force of the cross-shaped cutting blade is adjusted by the buffer adjustment unit during cutting, so that it can be resisted and rebounded when it contacts the battery cell's outer shell, while its sharp blade can complete the cutting of the adhesive material, avoiding damage to the battery cell's outer shell during peeling off the adhesive material, significantly improving the disassembly success rate.

Detailed Implementation

[0027] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0028] Please see Figures 1 to 8 The present invention provides a new energy vehicle battery pack disassembly and repair device, including a base 1, a battery cell 2, a clamping and rotating unit and a disassembly assembly. The clamping and rotating unit is disposed on the base 1 and the battery cell 2 is disposed on the clamping and rotating unit. The disassembly assembly includes a cutting transverse component 3, a cutting rotation chamber 4, multiple cross-cutting blades 5, multiple buffer adjustment units, and a scraper 6. The cutting transverse component 3 is disposed above the battery cell 2, the cutting rotation chamber 4 is disposed on one side of the cutting transverse component 3, the multiple buffer adjustment units are sequentially disposed inside the cutting rotation chamber 4, the multiple cross-cutting blades 5 are respectively disposed on the corresponding buffer adjustment units, and the scraper 6 is disposed on the other side of the cutting transverse component 3.

[0029] In this embodiment, the battery cell 2 is first placed on the clamping and rotating unit; then the cutting rotating chamber 4 moves above the battery cell 2, bringing the cross-shaped cutting tool 5 into contact with the outer wall of the battery cell 2; at this time, the cutting rotating chamber 4 rotates, and simultaneously the cutting lateral movement component 3 drives the cutting rotating chamber 4 to move laterally above the battery cell 2, cutting the adhesive material on the outside of the battery cell 2; then, the buffer adjustment unit adjusts the rebound resistance of the cross-shaped cutting tool 5, so that the resistance can penetrate the adhesive material but cannot scratch the outer shell of the battery cell 2; when the cross-shaped cutting tool 5 penetrates the adhesive material and contacts the outer shell of the battery cell 2, the buffer adjustment unit buffers the impact, allowing the cross-shaped cutting tool to... 5 is pushed and contracted; until the adhesive material of the battery cell 2 is cut off, the cutting transverse component 3 is moved, and the shovel 6 is used to shovel the cut adhesive material to remove it from the battery cell 2, thus completing the peeling off of the adhesive material; thereby, through the rotation of the cutting rotating chamber 4 and the movement of the cutting transverse component 3, the path is stable when cutting the adhesive material, and it is not easy to shake or deviate. At the same time, the spring force of the cross-cutting blade 5 is adjusted by the buffer adjustment unit during cutting, so that it can be resisted and rebounded when it comes into contact with the outer shell of the battery cell 2, while its own sharp blade can complete the cutting of the adhesive material, avoiding damage to the outer shell of the battery cell 2 when peeling off the adhesive material, and significantly improving the disassembly success rate.

[0030] Furthermore, the disassembly assembly also includes a bracket 7, two suspended moving parts 8, and two suspended lifting parts 9. The bracket 7 is mounted above the base 1. The two suspended moving parts 8 are sequentially arranged on the bracket 7. The output ends of the two suspended moving parts 8 are respectively provided with corresponding suspended lifting parts 9. The output ends of the two suspended lifting parts 9 are fixedly connected to the cutting transverse moving part 3.

[0031] In this embodiment, the bracket 7 supports the suspended moving component 8, the suspended moving component 8 is an electric slide rail, and the suspended lifting component 9 is a self-locking cylinder; first, the suspended lifting component 9 is started, which drives the cutting rotating chamber 4 below to approach the battery cell 2, and then the suspended moving component 8 is started, so that it moves and cooperates with each other to align the cross cutting blade 5 with the adhesive material on the outside of the battery cell 2.

[0032] Furthermore, the disassembly assembly also includes a flipping unit and two reinforcement mechanisms. The flipping unit is located at the output end of the cutting transverse component 3, the cutting rotating chamber 4 is located on the flipping unit, and the two reinforcement mechanisms are symmetrically arranged on both sides of the flipping unit.

[0033] In this embodiment, the flipping unit is used to flip the cutting rotating chamber 4 from below the cutting transverse component 3 to above, thereby making space below so that the shovel 6 can smoothly contact the battery cell 2, thereby shoveling away the loosened adhesive material caused by cutting; the reinforcing mechanism is used to reinforce and support the flipped cutting rotating chamber 4 to prevent shaking.

[0034] Furthermore, the flipping unit includes a flipping component 10, a flipping plate 11, and a cutting rotation component 12. The flipping component 10 is disposed at the output end of the cutting transverse component 3, the flipping plate 11 is disposed at the output end of the flipping component 10, and the cutting rotation component 12 is disposed on one side of the flipping plate 11. The output end of the cutting rotation component 12 passes through the flipping plate 11 and is fixedly connected to the cutting rotation chamber 4.

[0035] In this embodiment, both the flipping component 10 and the cutting rotating component 12 are self-locking motors. First, the flipping component 10 is started, which drives the flipping plate 11 to move, thereby driving the cutting rotating chamber 4 to flip. When the cutting rotating chamber 4 is running, the cutting rotating component 12 is started to drive it.

[0036] Furthermore, the reinforcement mechanism includes a reinforcement telescopic component 13, a reinforcement abutment component 14, and a reinforcement plate 15. The reinforcement telescopic component 13 is disposed on one side of the flipping component 10. The output end of the reinforcement telescopic component 13 is fixedly connected to the reinforcement abutment component 14, and the output end of the reinforcement abutment component 14 is fixedly connected to the reinforcement plate 15.

[0037] In this embodiment, both the reinforcing telescopic component 13 and the reinforcing abutment component 14 are self-locking cylinders. First, the reinforcing telescopic component 13 is activated, and the reinforcing abutment component 14 extends and moves to one side of the flip plate 11. At this time, the reinforcing abutment component 14 is activated, driving the reinforcing plate 15 to move and abut against one side of the flip plate 11, thereby achieving a reinforcing effect, reducing shaking, and providing support.

[0038] Furthermore, the buffer adjustment unit includes a telescopic column 16, a contact pad 17, a holding claw 18, a holding transmission mechanism, and a reset mechanism. The cross-shaped cutting tool 5 is provided with arc-shaped blades 19 on both sides. The cutting rotating chamber 4 has a buffer chamber 20. The telescopic column 16 is slidably connected to the buffer chamber 20. The contact pad 17 is provided on the outside of the telescopic column 16. The holding transmission mechanism and the reset mechanism are both provided inside the buffer chamber 20 and distributed on both sides of the telescopic column 16. The holding claw 18 is provided on the holding transmission mechanism.

[0039] In this embodiment, when cutting adhesive material, the holding claw 18 abuts against the contact pad 17, allowing the cross-shaped cutting tool 5 to contact the adhesive material and smoothly complete the cut until it penetrates the adhesive material and abuts against the outer shell of the battery cell 2. If the cutting rotating chamber 4 continues to rotate or presses closer to the battery cell 2 after abutting against the outer shell of the battery cell 2, the holding claw 18 will not be able to provide sufficient holding force, resulting in sliding between it and the contact pad 17. That is, the cross-shaped cutting tool 5 pushes the telescopic column 16 to slide and retract in the buffer chamber 20. This effectively avoids damage to the outer shell of the battery cell 2. After the cutting rotating chamber 4 rotates one revolution, all the cross-shaped cutting tools 5 have retracted. At this time, further rotation will not allow them to contact the adhesive material. At this time, the reset sub-mechanism can be activated to push the telescopic column 16 out and reset. In addition, the holding force of the holding claw 18 can be adjusted by the holding transmission mechanism to adapt to adhesive materials of different thicknesses or strengths.

[0040] Further, the abutting transmission mechanism includes an abutting transmission component 21, an abutting transmission rod 22, a first bevel gear 23, a second bevel gear 24, a stabilizing shaft 25, a threaded rod 26, a fixing plate 27, and two sliding plates 28. The abutting transmission component 21 is disposed on the inner side wall of the buffer chamber 20. The output end of the abutting transmission component 21 is fixedly connected to the abutting transmission rod 22. One end of the abutting transmission rod 22 is fixedly connected to the first bevel gear 23. The first bevel gear 23 and the second bevel gear 24 mesh with each other. The two ends of the stabilizing shaft 25... The fixed plate 27 is disposed inside the buffer chamber 20 and is rotatably connected to the second bevel gear 24 and the inner wall of the buffer chamber 20 respectively. One end of the threaded rod 26 is rotatably connected to the fixed plate 27, and the other end of the threaded rod 26 is fixedly connected to the second bevel gear 24. The abutting claw 18 is adapted to the threaded rod 26. The buffer chamber 20 has two sliding grooves 29. One end of each of the two sliding plates 28 is fixedly connected to the abutting claw 18, and the other end of each of the two sliding plates 28 is slidably connected to the corresponding sliding groove 29.

[0041] In this embodiment, the abutting transmission component 21 is a self-locking motor. After starting, it drives the abutting transmission rod 22 to rotate. The abutting transmission rod 22 drives the first bevel gear 23 to rotate, which in turn drives the second bevel gear 24 through meshing. Simultaneously, it rotates on the stabilizing shaft 25 to maintain the stability of the second bevel gear 24. The second bevel gear 24 drives the threaded rod 26 to rotate. The threaded rod 26 cooperates with the abutting claw 18, causing the abutting claw 18 to move within the buffer chamber 20. Consequently, the abutting claw 18 presses against the contact pad 17, generating a holding force. This prevents the cross-cutting blade 5 from being easily pushed back into the buffer chamber 20 when cutting adhesive materials. Furthermore, when the abutting claw 18 moves... The sliding plate 28 slides on the groove 29, preventing the holding claw 18 from easily shaking or shifting. When the cross-cutting blade 5 rotates, the arc-shaped blade 19 on the side first contacts the adhesive material and then penetrates into it. As the rotation continues, it can excavate a large area of ​​the adhesive material. Combined with the action of the cross-cutting blade 5, the cutting effect of the adhesive material can be significantly improved. In addition, by vertically moving the cutting rotating chamber 4, the cross-cutting blade 5 can press down on the adhesive material and cut it by the cutting edge of the cross-cutting blade 5 itself. Thus, the adhesive material can be cut in multiple ways, which significantly improves the cutting effect and efficiency compared to traditional blade cutting.

[0042] Furthermore, the reset mechanism includes a screw compressor 30, a reset plate 31, and a pressure sensor 32. The screw compressor 30 is disposed on the inner side wall of the buffer chamber 20, and the reset plate 31 is disposed at the output end of the screw compressor 30. The pressure sensor 32 is disposed on the reset plate 31.

[0043] In this embodiment, when the cross-shaped cutting tool 5 is fully pushed back and the telescopic column 16 contacts the pressure sensor 32, it indicates that neither the cross-shaped cutting tool 5 nor the arc-shaped blade 19 can contact the adhesive material. At this time, the screw compressor 30 can be started to move the reset plate 31, thereby pushing the telescopic column 16 out of the buffer chamber 20 again. At the same time, in order to reduce the pressure of the screw compressor 30 during the pushing out, the holding claw 18 can reduce some of the holding force.

[0044] Furthermore, the clamping and rotating unit includes a clamping and rotating component 33, a rotating disk 34, two clamping components 35, two clamping plates 36, and a plurality of clamping posts 37. The clamping and rotating component 33 is disposed below the base 1, and the output end of the clamping and rotating component 33 passes through the base 1 and is fixedly connected to the rotating disk 34. The battery cell 2 is placed on the rotating disk 34. The two clamping components 35 are symmetrically arranged on the base 1, and the output ends of the two clamping components 35 are respectively fixedly connected to the corresponding clamping plates 36. The plurality of clamping posts 37 are respectively disposed on the corresponding clamping plates 36.

[0045] In this embodiment, the clamping rotating component 33 is a self-locking motor, and the clamping component 35 is a self-locking cylinder. After the battery cell 2 is placed on the rotating disk 34, the clamping rotating component 33 is activated to drive the rotating disk 34 to rotate, thereby adjusting the position of the battery cell 2. After adjustment, the clamping component 35 is activated to drive the clamping plate 36 to move. Finally, the clamping post 37 holds the outer side of the battery cell 2, thus fixing it. Relying on the action of the clamping post 37, the entire plane of the clamping plate 36 can directly contact the battery cell 2, thereby avoiding squeezing the interface, electrode or component on the battery cell 2.

[0046] When using the new energy vehicle battery pack disassembly and repair device of this embodiment, the battery cell 2 is first placed on the clamping and rotating unit; then the cutting rotating chamber 4 moves above the battery cell 2, and the cross-shaped cutting blade 5 is brought into contact with the outer wall of the battery cell 2; at this time, the cutting rotating chamber 4 rotates, and the cutting lateral movement component 3 drives the cutting rotating chamber 4 to move laterally above the battery cell 2, cutting the adhesive material on the outside of the battery cell 2; then the buffer adjustment unit adjusts the rebound resistance of the cross-shaped cutting blade 5 so that the resistance can penetrate the adhesive material but cannot scratch the outer shell of the battery cell 2; when the cross-shaped cutting blade 5 penetrates the adhesive material and contacts the outer shell of the battery cell 2, the buffer adjustment unit buffers the impact, so that... The cross-shaped cutting blade 5 is retracted by pushing; after the adhesive material of the battery cell 2 is cut off, the cutting lateral movement component 3 is moved, and the shovel 6 shovels the cut adhesive material to remove it from the battery cell 2, thus completing the peeling off of the adhesive material; thereby, through the rotation of the cutting rotating chamber 4 and the movement of the cutting lateral movement component 3, the path is stable when cutting the adhesive material, and it is not easy to shake or deviate. At the same time, the spring force of the cross-shaped cutting blade 5 is adjusted by the buffer adjustment unit during cutting, so that it can be resisted and rebounded when it comes into contact with the outer shell of the battery cell 2, while its own sharp blade can complete the cutting of the adhesive material, avoiding damage to the outer shell of the battery cell 2 when peeling off the adhesive material, and significantly improving the disassembly success rate.

[0047] Please see Figure 9 The present invention also provides a method for disassembling and repairing a battery pack for a new energy vehicle, comprising the following steps: S1: Place the battery cell 2 on the clamping and rotating unit; S2: The cutting rotating chamber 4 moves above the battery cell 2 and makes the cross-cutting blade 5 fit against the outer wall of the battery cell 2; S3: The cutting rotating chamber 4 rotates, and at the same time the cutting transverse moving component 3 drives the cutting rotating chamber 4 to move transversely above the battery cell 2 to cut the adhesive material on the outside of the battery cell 2; S4: The springback resistance of the cross-cutting blade 5 is adjusted by the buffer adjustment unit so that the resistance can penetrate the adhesive material but cannot scratch the outer shell of the battery cell 2. S5: When the cross-cutting blade 5 penetrates the adhesive material and comes into contact with the outer shell of the battery cell 2, the buffer adjustment unit buffers the flow, causing the cross-cutting blade 5 to be pushed and retracted. S6: After the adhesive material of the battery cell 2 is cut off, the cutting transverse component 3 is moved, and the shovel 6 is used to shovel the cut adhesive material to remove it from the battery cell 2, thus completing the peeling off of the adhesive material.

[0048] The process involves placing the battery cell 2 on the clamping and rotating unit; moving the cutting rotating chamber 4 above the battery cell 2 and bringing the cross-shaped cutting tool 5 into contact with the outer wall of the battery cell 2; rotating the cutting rotating chamber 4 while the cutting lateral movement component 3 moves the cutting rotating chamber 4 laterally above the battery cell 2 to cut the adhesive material on the outside of the battery cell 2; adjusting the rebound resistance of the cross-shaped cutting tool 5 through the buffer adjustment unit to ensure that the resistance can penetrate the adhesive material but not scratch the outer shell of the battery cell 2; when the cross-shaped cutting tool 5 penetrates the adhesive material and contacts the outer shell of the battery cell 2, the buffer adjustment unit buffers the material, causing the cross-shaped cutting tool 5 to be pushed and retracted; after the adhesive material on the battery cell 2 is cut, the cutting lateral movement component 3 is moved, and the shovel 6 shovels the cut adhesive material to remove it from the battery cell 2, completing the peeling of the adhesive material.

10. A method for disassembling and repairing a new energy vehicle battery pack, using the new energy vehicle battery pack disassembly and repair device as described in claim 9, characterized in that, Includes the following steps: The battery cell is placed on the clamping and rotating unit; The cutting rotating chamber moves above the battery cell, bringing the cross-shaped cutting tool into contact with the outer wall of the battery cell; The cutting rotating chamber rotates, and at the same time, the cutting lateral movement component drives the cutting rotating chamber to move laterally above the battery cell to cut the adhesive material on the outside of the battery cell; The springback resistance of the cross-cutting blade is adjusted by the buffer adjustment unit so that the resistance can penetrate the adhesive material but cannot scratch the battery cell casing. When the cross-shaped cutting tool penetrates the adhesive material and comes into contact with the outer casing of the battery cell, the buffer adjustment unit buffers the flow, causing the cross-shaped cutting tool to be pushed and retracted. After the adhesive material of the battery cell is cut off, the cutting lateral component is moved, and the shovel blade is used to shovel the cut adhesive material off the battery cell, thus completing the peeling off of the adhesive material.
