[0001] The utility model relates to the technical field of dust brushing equipment, in particular to a dust brushing equipment for pole pieces used in the production and processing of lithium batteries. Background Art

[0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. The production of battery accessory pole pieces is generally completed by stamping. The battery pole piece raw materials are prepared before stamping. However, due to long-term storage, there will be dust on the surface of the battery pole piece raw materials, so the pole piece needs to be brushed.

[0003] The existing dust brushing device generally uses a cleaning brush to brush the surface of the pole piece, but the dust brushed by the cleaning brush will float in the air and still fall onto the surface of the pole piece, thereby affecting the cleaning effect of the pole piece.

One end of the limiting rod 3113 is fixedly connected to a pull rod 3114, and one side of the pull rod 3114 is fixedly connected to a spring 3115.

[0030] In this embodiment, the driving wheel 311 is fixedly connected to the outer wall of the second rotating shaft 322, and the first rotating shaft 315 is rotatably connected to the processing box 316 through a bearing.

At the same time, under the action of the pad 329, the electrode can be protected to prevent damage to the electrode caused by excessive pressure. When the electrode is fixed, the first telescopic rod 325 is manually controlled to drive the fixing seat 326 to adjust the height, so as to fine-tune the distance between the electrode and the brush 324 to a suitable position. Afterwards, the motor 321 is manually turned on to drive the second rotating shaft 322 to rotate through the motor 321, so that the brush roller 323 fixedly connected to the outer wall of the second rotating shaft 322 can be rotated, and then the brush 324 fixedly connected to the outer wall of the brush roller 323 can be rotated, and then the pole piece can be moved under the action of the slide rail 4 and the slider 5, so that the brush 324 can perform the first dust brushing treatment on the pole piece. When brushing the pole piece for the second time, the height of the pole piece can be slightly adjusted downward to prevent the brush 324 from damaging the pole piece due to a large cleaning force.
