Rather, these embodiments are provided to facilitate a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] The embodiment of the present application discloses a disassembly device, which is used to disassemble a battery pack 70, recover valuable materials in the battery pack 70, and perform disassembly analysis and verification on the battery pack 70. The battery pack 70 includes a cover plate 71.

[0033] Reference Figure 1 and Figure 2As shown, the disassembly device has a first direction X, a second direction Y, and a third direction Z that intersect with each other. The angles between the first direction X, the second direction Y, and the third direction Z are set according to the specific usage requirements. The embodiment of the present application does not make specific limitations on this. For example, the angles between the first direction X, the second direction Y, and the third direction Z are 90 degrees.

[0034] Reference Figures 1 to 5 As shown, the disassembly device includes a base 10, a clamping mechanism 40, a three-dimensional moving mechanism 20 and a rotary cutting mechanism 50. The clamping mechanism 40 is connected to the base 10 and is used to clamp the battery pack 70; the three-dimensional moving mechanism 20 is connected to the base 10, and the three-dimensional moving mechanism 20 is provided with a moving end 21, and the moving end 21 is used to realize movement along the first direction X, the second direction Y and the third direction Z; the rotary cutting mechanism 50 is connected to the mobile end 21, and the rotary cutting mechanism 50 is used to follow the moving cutting cover 71 of the mobile end 21.

[0036] The clamping mechanism 40 is used to clamp the battery pack 70 to fix the battery pack 70 and prevent the battery pack 70 from moving when the disassembly device cuts the cover plate 71, resulting in unstable cutting and even damage to the battery pack 70.

[0037] The mobile end 21 of the three-dimensional moving mechanism 20 is used to realize movement along the first direction X, the second direction Y and the third direction Z, so as to drive the rotary cutting mechanism 50 connected thereto to move along the first direction X, the second direction Y and the third direction Z, thereby realizing precise positioning of the mobile end 21 and the rotary cutting mechanism 50.

[0038] In the embodiment of the present application, the clamping mechanism 40 of the disassembly device is used to clamp the battery pack 70, and the mobile end 21 of the three-dimensional moving mechanism 20 is used to achieve movement along the first direction X, the second direction Y, and the third direction Z.

By clamping the battery pack 70, the three-dimensional moving mechanism 20, and the rotary cutting mechanism 50, the disassembly device can achieve precise cutting of the cover plate 71, thereby achieving safe, efficient, and non-destructive disassembly of the battery pack 70. Compared with manual disassembly of the battery pack 70, this device has the advantages of convenient disassembly and high efficiency. It also reduces the skill requirements for the disassembler, avoiding injuries to the disassembler and fires in the battery pack 70 caused by careless operation.

[0042] The cutter 52 can be a conventional technology, selected based on the intended use. For example, the cutter 52 can be a laser cutter. A laser cutter is an industrial processing device that uses a high-energy-density laser beam to cut materials. Laser cutters offer advantages such as high cutting accuracy, high cutting speed, a small heat-affected zone, contact-free cutting, and the ability to cut complex patterns and shapes.

[0047] The image acquisition element 60 can be conventional technology and can be selected based on the application requirements. For example, the image acquisition element 60 can be a 3D visual inspection camera.

[0064] Optionally, the disassembly device also includes a controller, which is respectively connected to the clamping mechanism 40, the three-dimensional moving mechanism 20 and the rotary cutting mechanism 50, and is used to comprehensively control the clamping mechanism 40, the three-dimensional moving mechanism 20 and the rotary cutting mechanism 50 to achieve precise cutting of the cover plate 71.

[0065] The disassembly device of the embodiment of the present application can be used for accurate, efficient, safe and non-destructive disassembly of the cover plate 71 of the battery pack 70. It is suitable for the serial-parallel connection structure between the single battery cells 73 using laser welding of the bus collector cover plate. It can avoid damage to the single battery cells 73 inside the battery pack 70 during the disassembly process and affect the secondary utilization, and has the advantage of higher safety.

[0066] Reference Figure 5 As shown, the battery pack 70 includes a cover plate 71 and a single battery cell 73 . A laser molten pool 72 is formed on the cover plate 71 when the cover plate 71 and the single battery cell 73 are combined by laser welding during the production process of the battery pack 70 .

[0067] The process of using the disassembly device is as follows, and refer to Figures 1 to 5 As shown:

[0068] 1. Place the battery pack 70 in the clamping space formed between the movable plate 42 and the fixed plate 41. The clamping drive 43 drives the movable plate 42 to move toward the fixed plate 41. The movable plate 42 and the fixed plate 41 clamp the battery pack 70 together, so that the battery pack 70 does not move when the disassembly device is working.

[0069] 2. The image acquisition element 60 acquires image information of the cover plate 71. The 3D motion mechanism 20 activates the first drive motor 241, the second drive motor 271, and the third drive motor 371 based on the image information. The first drive motor 241 rotates the first lead screw 242 to cause the first slider 30 to slide on the first guide rail 22, and the second lead screw 243 to cause the second slider 31 to slide on the second guide rail 34. When the rotary cutting mechanism 50 moves in the first direction X, above the first row of laser molten pools 72, the first drive motor 241 stops.

[0070] The second drive motor 271 drives the third lead screw 272 to rotate, causing the third slider 33 to slide on the first vertical support member 26, and drives the fourth lead screw 273 to rotate, causing the fourth slider 36 to slide on the second vertical support member 35, thereby causing the horizontal connector 25 to drive the rotary cutting mechanism 50 to move downward toward the cover plate 71. When the cutter 52 in the rotary cutting mechanism 50 reaches a preset distance above the laser molten pool 72 (the preset distance is set according to usage requirements, for example, the preset distance is 1 mm or 2 mm along the third direction Z between the lower end of the cutter 52 and the plane of the laser molten pool 72), the second drive motor 271 stops.

[0071] The third drive motor 371 drives the fifth lead screw 372 to rotate so that the movable end 21 slides on the horizontal connecting member 25, so that the movable end 21 drives the cutter 52 to move. When the cutter 52 faces the laser molten pool 72, the third drive motor 371 stops working.

[0072] 3. Then, the image acquisition element 60 identifies the laser molten pool 72 in the cover plate 71 on the top of the battery pack 70, and under the action of the controller, issues an instruction to the cutter 52 to accurately cut a concentric circle on the outer circle of the laser molten pool 72 that is larger than the laser molten pool 72 by a preset size (the preset size is set according to the use requirements, for example, the preset distance is 2mm or 3mm). The cut concentric circle completely penetrates the cover plate 71 without damaging the battery pole 74 of the single battery cell 73.

[0073] 4. After the cutter 52 completes cutting of a laser molten pool 72, the cutter 52 moves in the second direction Y driven by the second drive motor 271 under the drive of the movable end 21. After the cutter 52 reaches above the next laser molten pool 72, the above step 4 is repeated until all the laser molten pools 72 along the first row of the battery pack 70 in the second direction Y are cut.

[0074] 5. After the first row of laser molten pools 72 along the length of the battery pack 70 is completely cut along the second direction Y, the first drive motor 241 drives the first lead screw 242 to rotate, causing the first slider 30 to slide on the first guide rail 22, and drives the second lead screw 243 to rotate, causing the second slider 31 to slide on the second guide rail 34. This causes the movable end 21 to drive the cutter 52 to move along the first direction X. When the cutter 52 moves to the next row of laser molten pools 72, the first drive motor 241 stops. Steps 3 and 4 are repeated.

[0075] Repeat the above steps 3, 4 and 5 until the cutting of the laser molten pool 72 on the cover plate 71 is completed, and the separation of the cover plate 71 and the single battery cell 73 is completed.

[0076] In the embodiment of the present application, the clamping mechanism 40 of the disassembly device is used to clamp the battery pack 70, and the mobile end 21 of the three-dimensional moving mechanism 20 is used to achieve movement along the first direction X, the second direction Y, and the third direction Z. The rotary cutting mechanism 50 is connected to the mobile end 21 and is used to cut the cover plate 71 according to the movement of the mobile end 21. By clamping the battery pack 70, the three-dimensional moving mechanism 20, and the rotary cutting mechanism 50, the disassembly device can achieve precise cutting of the cover plate 71, thereby achieving safe, efficient, and non-destructive disassembly of the battery pack 70. Compared with manual disassembly of the battery pack 70, this device has the advantages of convenient disassembly and high efficiency. It also reduces the skill requirements for the disassembler, avoiding injuries to the disassembler and fires in the battery pack 70 caused by careless operation.
