Piece dividing method for battery cell pole piece feeding

Abstract

The invention discloses a piece dividing method for battery cell pole piece feeding. The piece dividing method comprises the following steps that a first pressing device moves upwards, at least one first airflow nozzle discharges first airflow, and the first airflow acts on pole pieces in a pole piece storage device, so that parts of the pole pieces on the uppermost layer arch upwards; an adsorption device adsorbs the first pole pieces, the first pole pieces are the pole pieces in direct contact with the adsorption device, a second airflow nozzle discharges second airflow, the second airflow acts on the pole pieces, the second airflow blows off the second pole pieces, and the second pole pieces are the pole pieces adhered to the first pole pieces; and the first pole pieces move from the pole piece storage device to a transmission device, so that the first pole pieces are far away from the first pressing device, and the first pressing device resets and presses the pole pieces in the pole piece storage device. By means of the piece dividing method for battery cell pole piece feeding, the time for pole piece dividing and pole piece positioning can be saved, the machining efficiency isimproved, and the purpose of single piece feeding is effectively achieved.

Description

Technical field [0001] The present invention relates to the technical field of lithium batteries, and in particular to a method for slicing the pole pieces of a battery. Background technique [0002] Due to the advantages of long service life, high rated voltage, low self-discharge rate, high storage energy density and high power endurance, lithium batteries have a good development trend. In the manufacture of lithium batteries, battery cells are shaped Craftsmanship plays an important role. Among them, the cell forming process includes a pole piece feeding process, and the quality of the pole piece feeding method is related to the quality and efficiency of subsequent cell forming. In the prior art, the sucker-type manipulator is often used to absorb the pole pieces for loading. It is necessary to use visual positioning to locate the pole pieces. The visual positioning requires a certain feedback time, which affects the efficiency of grabbing the pole pieces. There is an adsorp...

Problems solved by technology

In the prior art, the suction cup-type manipulator is often used to absorb the pole piece for loading. It is necessary to use visual positioning to locate the pole piece. The visual positioning requires a certain feedback time, which affects the efficiency of grabbing the pole piece. At the same time, due to the There is an adsorption force between them, and the redundant pole piece needs to be shaken off by shaking action, and a certain amount of time needs to be reserved during the shaking off process, resulting in low efficiency of material retrieving during the feeding process
