Dedusting feeding device for battery pole pieces and dedusting system of battery pole pieces

Abstract

The invention provides a dedusting feeding device for battery pole pieces and a dedusting system of battery pole pieces. Two cylindrical rollers and a plurality of rolling pieces are included. According to the dedusting feeding device for battery pole pieces and the dedusting system of battery pole pieces, by arranging the rolling pieces on the roller, pole pieces are separated from the peripheralside face of each cylindrical roller by means of the supporting action of the rolling pieces; sliding friction is replaced by rolling friction to reduce the factors of friction of the pole pieces asfar as possible, so that the probability of a micro short circuit formed on the pole pieces is reduced. By forming a vent hole, impurities on the pole pieces can be removed by way of adsorption; an inner ring and an outer ring are designed, so that the stability of the rolling pieces on each cylindrical roller and the adsorption effect of the vent hole can be guaranteed, and meanwhile, the vent hole has a certain adsorption effect to the pole pieces to prevent the pole pieces from falling from each cylindrical roller. The two cylindrical rollers are arranged in a staggered manner, so that thepole pieces between the two cylindrical rollers generate certain tension, and the dedusting effect is improved.

Description

technical field [0001] The invention relates to the field of battery auxiliary equipment, in particular to a battery pole piece dust removal and feeding device and a battery pole piece dust removal system. Background technique [0002] With the continuous development of electronic technology, the performance requirements and quantity requirements for lithium-ion batteries are also getting higher and higher. During the manufacturing process of lithium-ion batteries, dust particles will have a great impact on the performance of the subsequent finished battery cells. The clean room can reduce the dust particle pollution in the manufacturing workshop, but it cannot remove the floating dust or curls on the pole pieces. In the prior art, trays are used to carry the pole pieces for the powder particles generated during the winding process, and the powder and floating dust on the surface are removed by blowing air or a brush with air suction during the winding process of the pole pi...

AI Technical Summary

Problems solved by technology

During the manufacturing process of lithium-ion batteries, dust particles will have a great impact on the performance of the subsequent finished battery cells. The clean room can reduce the dust particle pollution in the manufacturing workshop, but it cannot remove the floating dust or curls on the pole pieces. In the prior art, trays are used to carry the pole pieces for the powder particles generated during the winding process, and the powder and floating dust on the surface are removed by blowing air or a brush with air suction during the winding process of the pole pieces. Due to the friction between the pole pieces or the friction between the pole pieces and the tray, a micro-short circuit is formed inside the formed lithium-ion battery, which in turn causes the problem of excessive voltage drop rate of the battery.
