The brush lateral movement assembly 3 and the dust collection hood 4 are mounted on the bracket 1. The brush lateral movement assembly 3 drives the two brush assemblies 2 to move relative to each other, thereby bringing the two brush assemblies 2 closer together to clean the electrode surface passing through the brush assembly 2. The dust collection hood 4 receives negative air pressure, and the dust swept out by the brush assembly 2 is absorbed and collected by the dust collection hood 4 to prevent dust from flying.

[0018] The brush assembly 2 includes a brush holder 23, a brush structure 22, a brush rotating structure 21, a positioning wing screw 24, and a locking structure 25. The brush structure 22, the brush rotating structure 21, the positioning wing screw 24, and the locking structure 25 are mounted on the brush holder 23. The brush rotating structure 21 drives the brush structure 22 to rotate, thereby causing the brush structure 22 to rotate and clean the electrode sheet evenly. The positioning wing screw 24 and the locking structure 25 abut against the brush structure 22 respectively. The positioning wing screw 24 is used to position the brush structure 22, and the locking structure 25 is used to prevent the brush structure 22 from detaching from the brush holder 23.

The inner bearing housing 215 and the motor base 212 are fixed on the brush bracket 23. The motor 211 is mounted on the motor base 212. The motor base 212 and the inner bearing housing 215 are mounted on the brush bracket 23. The motor 212 is connected to the guide shaft 214 through the coupling 213. The second bearing 216 is mounted in the inner bearing housing 215 and is sleeved on the guide shaft 214. The guide shaft 214 passes through the brush 224. A limit pin 2141 is provided on the guide shaft 214, and a groove 2241 is provided at one end of the brush 224. The limit pin 2141 is engaged in the groove 2241. A guide groove 2242 is provided at the opening of the groove 2241 to guide the limit pin 2141 into the groove 2241. The locking structure 25 includes a locking wing screw 252 and a locking baffle 251. The locking wing screw 252 passes through the locking baffle 251 and is threadedly connected to the brush bracket 23. The locking baffle 251 abuts against the outer bearing seat 221.

[0021] When it is necessary to assemble the brush structure 22, align the brush 224 with the guide shaft 214 so that the brush 224 is sleeved on the guide shaft 214. Push the handle 222 so that the brush 224 slides along the guide shaft 214 and the limit pin 2141 enters the slot 2241 along the wire groove 2242, that is, the brush structure 22 is installed in place. Operate the locking wing screw 252 so that the locking baffle 251 abuts against the outer bearing seat 221, thereby locking the outer bearing seat 221. Then operate the positioning wing screw 24 so that the positioning wing screw 24 is locked and fixed to the outer bearing seat 221, thereby realizing the assembly of the brush structure 22.

[0022] When it is necessary to disassemble the brush structure 22, first operate the positioning wing screw 24 to separate the positioning wing screw 24 from the outer bearing seat 221, operate the locking wing screw 252 to separate the locking baffle 251 from the outer bearing seat 221, and operate the handle 222 to disengage the brush 224 from the guide shaft 214, thereby realizing the disassembly of the brush structure 22.
