In addition, the device has a high degree of automation and higher disassembly efficiency.

[0030] Combination Figures 1 to 4 As shown, the device of this embodiment includes a milling part 10, a positioning part 20 and a driving part 30. The milling part 10 disassembles the bus of the battery module, the positioning part 20 can position the weld on the bus before disassembly and milling, and the driving part 30 can drive the milling part 10 and the positioning part 20 to move, so that the positioning operation and the milling operation can be carried out smoothly.

[0031] In this embodiment, the milling part 10 includes a milling motor 11 and a milling tool 12. The milling motor 11 drives the milling tool 12 to disassemble the weld of the bus. After the weld is milled, the bus can be disassembled without damaging the battery cell poles, which is beneficial to the recycling of the battery cell.

[0032] See also Figure 2and Figure 4 The positioning part 20 includes a first positioning member 21 and a second positioning member 22. The first positioning member 21 is used to determine the position coordinates of the busbar weld in the first direction and the second direction, and the second positioning member 22 is used to determine the position coordinates of the busbar weld in the third direction. The first positioning member 21 of this embodiment includes a camera 211 and a light source 212. The light source 212 is located at the front end of the lens of the camera 211 to illuminate the camera 211, and the second positioning member 22 is a laser rangefinder.

[0033] Specifically, with the cooperation of the camera 211 and the light source 212, the position coordinates of the busbar weld in the first direction and the second direction are determined, and the laser rangefinder can determine the position coordinates of the busbar weld in the third direction. The first direction and the second direction of this embodiment are the XY axis directions, and the third direction is the Z axis direction. Combined with the thickness parameters of the busbar itself, the milling operation of the busbar weld can be accurately performed. The positioning part 20 of this embodiment adopts a combination of a visual system and a laser ranging system, which effectively ensures the overall milling accuracy and high flexibility of the device, making its operation more precise and the milling effect better.

[0034] In this embodiment, the positioning portion 20 is connected to the milling motor 11 through the mounting block 40, and the mounting block 40 is provided with a first fixed block 41 and a second fixed block 42. The camera 211 is detachably connected to the first fixed block 41, and the light source 212 is detachably connected to the second fixed block 42. The presence of the first fixed block 41 and the second fixed block 42 facilitates the adjustment of the positions of the camera 211 and the light source 212, which is beneficial to the precise positioning of the bus weld.

[0035] Specifically, the first fixed block 41 is provided with a plurality of first holes, the camera 211 is installed in one of the first holes, the second fixed block 42 is provided with a plurality of second holes, the light source 212 is installed in one of the second holes through a mounting plate, the camera 211 changes its installation position by selecting different first holes, and the light source 212 can change its installation position by selecting different second holes, thereby meeting the positioning requirements for the busbar weld.

[0036] Combination Figure 2 and Figure 4 As shown, a blocking portion 50 is provided on the mounting block 40, and the blocking portion 50 includes a driving cylinder 51 and a blocking cover 52. The driving cylinder 51 drives the blocking cover 52 to protect the light source 212. When the bus weld needs to be milled, the driving cylinder 51 drives the blocking cover 52 to rotate, and the blocking cover 52 protects the light source 212, so as to protect the camera 211 and the light source 212.

[0037] See also Figure 2 and Figure 3A blowing part 60 is provided on the mounting block 40, and the blowing part 60 includes an air connecting pipe 61, a mounting plate 62 and a nozzle 63. The air connecting pipe 61 supplies air to the nozzle 63, and the jet direction of the nozzle 63 is the same as the direction of the milling tool 12. During the milling process of the busbar weld, the nozzle 63 will continue to jet to deal with impurities generated by milling.

[0038] Specifically, there are a plurality of nozzles 63 which are spaced apart around the circumference of the milling cutter 12 , so that impurities generated by milling can be uniformly processed.

[0039] In this embodiment, the driving unit 30 is a six-axis manipulator, and the milling unit 10 is installed on the six-axis manipulator, which has a higher degree of freedom and is compatible with busbar milling of battery modules of various specifications, and has greater versatility.

[0040] In actual use of the milling device for disassembling the battery module of this embodiment, the milling part 10 can mill the weld of the busbar, thereby realizing the disassembly of the busbar, and the positioning part 20 can determine the weld of the busbar from the XYZ axis direction. Combined with the thickness parameters of the busbar itself, precise milling of the busbar can be achieved. The existence of the driving part 30 can drive the positioning part 20 to move. After the positioning part 20 determines the weld coordinates of the busbar, the driving part 30 drives the milling part 10 to move, and the milling part 10 precisely mills the weld of the busbar.
