Abstract

The invention relates to a lithium battery electrode sheet cleaning device and method, and aims to provide the lithium battery electrode sheet cleaning device and the lithium battery electrode sheet cleaning method capable of cleaning metal filings and dust on the surface of an electrode sheet and metal filings and dust on a cut part at the edge of the electrode sheet. The lithium battery electrode sheet cleaning device comprises an upper adsorption conveying belt, a lower adsorption conveying belt, an upper vacuum adsorption plate, a lower vacuum adsorption plate, an edge cleaning device, a lower surface cleaning device and an upper surface cleaning device, wherein the conversion of upper/lower surface adsorption is realized through an internal adsorption cavity of the upper vacuum adsorption plate on the upper adsorption conveying belt and the lower vacuum adsorption plate on the lower adsorption conveying belt; and the cleaning is performed through a left edge cleaning device, a right edge cleaning device, the lower surface cleaning device and the upper surface cleaning device in sequence. The lithium battery electrode sheet cleaning device and the lithium battery electrode sheet cleaning method have the beneficial effects that the metal filings and the dust on the surface of the electrode sheet and the metal filings and the dust on the cut part at the edge of the electrode sheet can be cleaned and on-line continuous cleaning can be realized.

Description

technical field [0001] The invention relates to a soft material cleaning method and a device thereof, in particular to a lithium battery electrode sheet cleaning device and a method thereof. Background technique [0002] During the manufacturing and processing of lithium batteries, it is necessary to strictly control metal filings and dust, especially dust with a diameter of more than 8um, so as to avoid internal short circuit of the battery, increase the self-discharge rate of the battery and even cause safety hazards. The metal shavings and dust of the lithium battery electrode sheet mainly come from: the dust on the surface of the raw material of the lithium battery electrode sheet and the metal shavings and dust during the processing of the lithium battery electrode sheet, and the metal shavings and dust during the processing of the lithium battery electrode sheet Chips and dust are mainly concentrated in the cutting edge. The basic principle of cleaning the lithium bat...
