[0032] The structure and working principle of the electrode surface powder brushing device of the present invention are described in detail below.

[0033] The utility model relates to a powder brushing device for the surface of an electrode, which is mainly used for removing dust from the electrode and ensuring the cleanliness of the electrode.

[0034] The support seat 6 is used to support the overall structure, which ensures stability during operation. The first brush group 1 and the second brush group 2 are respectively fixed on top of it, and the pole piece passes through the middle of the first brush group 1 and the second brush group 2; the first cylinder group 3 and the second cylinder group 4 respectively adjust the movement of the first brush group 1 and the second brush group 2. Its function is to open and close the first brush group 1 and the second brush group 2 through the telescopic movement of the cylinder, and adjust the pressure of the brush on the pole piece for dust removal. On the other hand, it is more convenient for pole piece replacement and maintenance.

[0035] The width adjustment group 5 is installed on top of the support seat 6 through the Y-axis module. Above the width adjustment group 5 are the first brush group 1 and the second brush group 2. In front of the width adjustment group 5 is a handle, which is convenient for moving the whole back and forth to adapt to different width requirements and ensure dust removal on the effective surface of the brush and the electrode. There is a scale on the side of the width adjustment group 5. After adjusting the width direction, it is locked by bolts to make the brush as a whole stable and not deviated.

[0036] The dust suction pipe 7 is installed at the bottom of the first brush group 1 and the second brush group 2, and is connected to the dust removal pipe 13 behind the large plate through a hose after being led out.

[0037] The first brush 8 is connected to the first brush drive motor 9 through a first coupling to provide stable power for the first brush 8. The second brush is connected to the second brush drive motor through a second coupling to provide stable power for the second brush. The first brush 8 and the second brush are fixed with mounting plates around them, and the filter below is connected to the dust suction pipe 7. Working space is reserved on the side so that the first brush 8 and the second brush can brush the powder electrode at the same time.

[0038] On one side of the first coupling, there is a first brush adjustment block 10 and a first brush adjustment bolt 11, and on the second coupling side, there are a second brush adjustment block and a second brush adjustment bolt. The first brush 8 and the second brush will wear out after long-term use. The first brush adjustment bolt 11 is used to adjust the distance between the first brush adjustment block 10 to adjust the position of the first brush 8. The second brush adjustment bolt is used to adjust the distance between the second brush adjustment block to adjust the position of the second brush, so that the first brush 8 and the second brush have the same force on the electrode powder.

[0039] The guide plate 12 can be installed on both sides of the first brush 8 and the second brush, and its position is determined according to the direction of the pole piece and the pole ear. Its function is to guide the pole ear (foil area) and prevent the brush from damaging the pole ear; a dust removal pipe 13 is installed under the first brush 8 and the second brush, which is a quick-disassembly type for easy maintenance and cleaning.

[0040] The utility model has the advantages of delicate structure, high stability and flexible adjustment, and has obvious powder brushing and dust removal effect on the pole pieces, which can prevent the dust on the pole pieces from affecting the performance of the lithium battery and further improve the quality of the pole pieces.
