[0033] Example:

[0034] See Figure 2 The six sides of the battery cell 10 are described in detail. The battery cell 10 refers to a prismatic battery cell 10. The battery cell 10 includes... Figure 2 The front side, the back side which is set opposite the front side, the top surface which is set on the left side, the bottom surface which is set on the right side, and the two sides which are set in the vertical direction;

[0035] like Figure 1 As shown, a six-sided cleaning device for a square-shell battery cell includes a brush cleaning device 200. The brush cleaning device 200 is mainly used to clean the bottom, front and back of the battery cell 10. After cleaning with the brush, the dust and other stains on the surface of the battery cell 10 can be quickly removed. In conjunction with the first suction nozzle 240, the removed dust can be collected in a unified manner.

[0036] A mechanical gripper 100 is disposed adjacent to the brush cleaning device 200. The mechanical gripper 100 is typically disposed to the side of the brush cleaning device 200. The mechanical gripper 100 is used to grip the battery cell 10, and the battery cell 10 is cleaned by the brush cleaning device 200 under the gripping and moving action of the mechanical gripper 100. Furthermore, the mechanical gripper 100 moves the battery cell 10 onto the battery cell transfer platform 300. In order to ensure that the brush cleaning device 200 can effectively clean the bottom, front, and back surfaces of the battery cell 10, the mechanical gripper 100 preferably grips two sides of the battery cell 10.

[0037] The battery cell transfer platform 300 is located adjacent to the brush cleaning device 200. In one embodiment, the transfer direction of the battery cell transfer platform 300 is preferably on the same straight line as the channel direction inside the brush cleaning device 200. This facilitates the mechanical gripper 100 to move in a straight line during transport, thereby improving the transfer speed.

[0038] The ion air cleaning device 400 is located in the middle of the battery cell transfer platform 300. It can be understood that the side of the battery cell transfer platform 300 near the brush cleaning device 200 can be used to receive and position the battery cell 10. After the battery cell 10 is positioned, the battery cell transfer platform 300 transfers the battery cell 10 to the ion air cleaning device 400 for further cleaning. After cleaning, the battery cell transfer platform 300 transfers the battery cell 10 to the tail end of the battery cell transfer platform 300, and the cleaned battery cell 10 can be transferred to the next process by a robotic arm.

[0039] like Figure 3 As shown, in one embodiment, the brush cleaning device 200 includes a bottom roller brush cleaning device 210, a side roller brush cleaning device 220, and a first ion air knife 230 arranged sequentially along the traveling direction of the battery cell 10; the traveling direction of the battery cell 10 refers to the direction from the lower right corner to the upper left corner, that is... Figure 2 The middle arrow indicates the direction; the bottom roller brush cleaning device 210 and the side roller brush cleaning device 220 have the same driving device, both including a first drive motor 201 and a first drive belt 202; the first drive motor 201 is connected to the roller brush through the first drive belt 202, thereby driving the roller brush to rotate and cleaning the bottom, front and back of the battery cell 10; since the brush on the outside of the roller brush has good softness, although the roller brush of the side roller brush cleaning device 220 mainly cleans the back and front, it can also perform some preliminary cleaning on the two sides of the battery cell 10 at the same time;

[0040] The brush cleaning device 200 has a first suction port 240 at its bottom; the ion wind cleaning device 400 has a second suction port 450 at its bottom; the first suction port 240 and / or the second suction port 450 are connected to an anemometer 500. It should be noted that the first suction port 240 is also connected to a suction device (not shown in the figure), which is connected to the bottom of the first suction port 240 via a pipe. The suction pipe is also connected to an anemometer 500 to measure the wind speed during suction, thus monitoring the suction effect.

[0041] Similarly, the second suction nozzle 450 is also connected to a suction device (not shown in the figure). The suction device is connected to the bottom of the second suction nozzle 450 through a pipe. The suction pipe is also connected to an anemometer 500 to measure the wind speed during suction, which can be used to monitor the suction effect. The suction devices connecting the first suction nozzle 240 and the second suction nozzle 450 can be two or share one.

[0042] In one embodiment, the air outlet of the first ion air knife 230 is tilted toward the direction of the cell transfer platform 300. That is, the air blown out by the first ion air knife 230 blows the dust on the surface of the cell 10 toward the outside of the brush cleaning device 200. The advantage of this is that it can prevent the dust from directly adhering to the roller brush when blowing inward. When blowing outward, the dust floats and falls downward. With the suction effect of the bottom first suction horn 240, the dust blown outward can enter the first suction horn 240 from the bottom, thereby reducing the problem of a large amount of dust adhering to the roller brush.

[0043] like Figure 2 As shown, in one embodiment, the mechanical gripper 100 includes a connecting frame 110; the connecting frame 110 is provided with a plurality of gripper assemblies 120; in one embodiment, the gripper assembly 120 includes four grippers.

[0046] In one embodiment, a limiting block 331 is fixedly provided on the transfer platform 330; a positioning block 333 is provided on the opposite side of the limiting block 331; the positioning block 333 is connected to the movable rod of the positioning cylinder 332; the positioning cylinder 332 drives the positioning hole to approach or move away from the limiting block 331 to achieve clamping and releasing of the battery cell 10; after the positioning block 333 clamps the battery cell 10, the second drive belt 350 can transfer the battery cell 10 to the ion wind cleaning device 400 for cleaning;

[0047] In one embodiment, a third pulley 361 is connected to the output shaft of the second drive motor 340; the third pulley 361 is connected to a fourth pulley 362 via a third drive belt 360; the fourth pulley 362 is coaxially arranged with the first pulley 351 and rotates synchronously.

[0049] like Figure 6As shown, in one embodiment, the isolation chamber 410 is provided with a support frame 420; a first bracket 430 is slidably connected to the support frame 420; a plurality of second ion air knives 431 are connected to the first bracket 430; a third ion air knife 441 is connected to the first bracket 430 through a second bracket 440; the length direction of the second ion air knife 431 is perpendicular to the length direction of the third ion air knife 441. The second ion air knife 431 is mainly used to remove dust from the two sides of the battery cell 10, and the third ion air knife 441 is mainly used to remove dust from the top surface of the battery cell 10. In one embodiment, the third ion air knife 441 is rotatably connected to the second bracket 440, and the tilt angle of the third ion air knife 441 can be adjusted as needed. After adjusting to the required angle, it is fixed by screws. In one embodiment, the second bracket 440 is connected to both ends of the first bracket 430, and two second brackets 440 are provided. The length of the third ion air knife 441 is approximately equal to the length of the support frame 420.

[0050] like Figure 6 As shown, in one embodiment, the air outlet of the second ion air knife 431 is set at an angle. The angled second ion air knife 431 can better align the air outlet with the two sides of the battery cell 10, resulting in better dust removal.
