Automatic dust removal device for pole piece

Abstract

The invention relates to the technical field of flexible-package battery pole piece forming, in particular to an automatic dust removal device for a pole piece. The automatic dust removal device for the pole piece comprises a housing and a vacuum conveyor belt which passes through the housing, wherein a powder-brushing dust absorbing device and a powder-blowing dust absorbing device are sequentially arranged in a transport direction of the pole piece above the vacuum conveyor belt; a self-cleaning device is arranged below the vacuum conveyor belt; and the powder-brushing dust absorbing deviceand the powder-blowing dust absorbing device are arranged in the housing. According to the automatic dust removal device for the pole piece, the powder-brushing dust absorbing device loosens dust, thepowder-blowing dust absorbing device strongly blows up dust, and the self-cleaning device takes away dust, so that the pole piece dust removal is more complete; dust removal is performed in a relatively sealed vacuum space, so that impurities are prevented from flying, and therefore, cleanliness of the working space is improved; and the vacuum conveyor belt has a self-cleaning function, so that aproduct is prevented from being polluted from a second time.

Description

Technical field [0001] The invention relates to the technical field of forming the pole piece of a soft pack battery, in particular to an automatic dust removal device for the pole piece. Background technique [0002] The dust removal of the soft-pack battery pole piece is located after the pole piece is formed and cut. Since the pole piece is translated, formed, and cut, a lot of dust will be formed on the surface and cut surface of the pole piece. If the dust is not effectively removed, it will flow into the bottom One process will cause the battery to short circuit. Existing dust removal methods mainly use brushes and vacuum suction, which have unsatisfactory dust removal effect and are prone to secondary pollution, which ultimately leads to a high short-circuit rate of the battery. Summary of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide an automatic pole piece dust removal de...

Problems solved by technology

[0002] The dust removal of the pole piece of the soft pack battery is located after the pole piece is formed and cut. Since the pole piece will form a lot of dust on the surface of the pole piece and the cut surface during the process of translation, tab forming, and cutting, if the dust cannot be effectively removed, it will flow into the lower A process that will cause a short circuit in the battery

The existing dust removal methods mainly use brushes and vacuum suction. The dust removal effect is not ideal, and it is easy to cause secondary pollution, which eventually leads to a high short circuit rate of the battery.
