Description

Pole piece dust collector Technical Field The utility model relates to the technical field of batteries, in particular to a pole piece dust removal device. Background In the production and use process of the battery pole piece, the lug is subjected to die cutting by using a laser die cutting machine, dust, metal particles and other impurities can be generated in the process, and part of the impurities can adhere to the pole piece and possibly cause risks such as battery short circuit, ignition and explosion, so that dust removal treatment is required to be carried out on the surface of the pole piece. The traditional dust removing method mostly adopts a brush to remove dust, but the contact type dust removing mode of the brush is easy to damage the pole piece, and the protruding part of the edge of the pole piece coil stock corresponding to the pole lug is easy to be brushed by the brush, so that the using effect is influenced. In addition, because the brush can adhere more dust after long-term operation, secondary pollution is easily caused to the polar plate. Disclosure of utility model The utility model aims to solve the technical problems that the existing pole piece dust removing device is easy to damage a pole piece and is not thoroughly cleaned. In order to solve the technical problems, the pole piece dust removing device comprises a dust removing box, wherein a dust blowing cavity connected with a positive pressure air source, a first dust collecting cavity connected with a negative pressure air source and a second dust collecting cavity are arranged in the dust removing box, a slit hole, a first dust collecting hole and a second dust collecting hole are formed in the bottom of the dust removing box, the slit hole is communicated with the dust blowing cavity, the first dust collecting hole is communicated with the first dust collecting cavity, and the second dust collecting hole is communicated with the second dust collecting cavity. Further, in the pole piece dust removing device provided by the utility model, the pole piece dust removing device further comprises an air inlet piece, wherein the air inlet piece is positioned in the dust blowing cavity, an air inlet channel is arranged in the air inlet piece, the dust removing box is provided with an air inlet, and the air inlet is communicated with the air inlet channel. Further, in the pole piece dust removal device disclosed by the utility model, the air inlet channel comprises an air guide channel and a plurality of flow dividing channels, the air guide channel is communicated with the air inlet, and the flow dividing channels are respectively communicated with the air guide channel and the dust blowing cavity.
