Electrode pole piece rolling cleaning device for production of lithium ion batteries

Abstract

The invention discloses an electrode pole piece rolling cleaning device for production of lithium ion batteries. The device includes a lower pressing roller, an upper pressing roller and a pole piecetightly pressed between the lower pressing roller and the upper pressing roller, wherein the lower pressing roller and the upper pressing roller are mounted on a roller press. The upper pressing roller is mounted on the roller press through two mounting plates on the front and rear sides, and a cleaning box and a residue receiving box are mounted on the two sides of the lower ends of the two mounting plates respectively. The electrode pole piece rolling cleaning device for the production of the lithium ion batteries has the advantages that powder on the outer surfaces of the rollers can be stably and thoroughly scraped off for a long time, and the service life is long.

Description

technical field [0001] The invention relates to the field of lithium ion battery production, in particular to a roll cleaning device for electrode pole pieces used in lithium ion battery production. Background technique [0002] The rolling machine is one of the necessary production equipment in the lithium battery manufacturing industry. Its function is to increase the density of the positive and negative pole pieces by rolling, so that the energy density of the assembled battery is greatly improved. A pair of rolls of the rolling press have high precision, and the surface of the rolls must be impregnated, quenched, etc. to achieve high hardness. After the production task is finished, it is often necessary to clean the outer surface of the roll. The general roll press is equipped with a powder scraping mechanism, that is, a non-metallic blade is used to scrape off the powder remaining on the outer surface of the roll, and then the user uses a Clean the outer surface of the...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of electrode pole sheet roll cleaning device for lithium-ion battery production in order to solve the above problems, to solve the poor effect when scraping the powder remaining on the outer surface of the roll with a scraper in the prior art, After a long time of use, the blade is prone to curling, which makes it difficult to remove the powder on the outer surface of the roll, etc.
