Abstract

The invention discloses a method for preventing positive and negative electrode dust cross contamination in a baking process. According to the method, transfer equipment and at least two sets of dustremoval equipment are adopted, wherein the transfer equipment removes dust in the positive electrode dust removal equipment and the negative electrode dust removal equipment. The dust removal of the transfer equipment comprises the following steps that: 1, a mechanical arm stretches into the dust removal equipment, high-pressure air blows towards a to-be-dedusted surface of the mechanical arm, anddust on the to-be-dedusted surface is swept through a brush; 2, the mechanical arm extends out of the dust removal equipment, the position of the to-be-dedusted surface is adjusted, and the mechanical arm extends into the dust removal equipment; and 3, the mechanical arm extends out of the dust removal equipment. With the method of the invention adopted, the problem of dust cross contamination when dust exists on a positive electrode roll and a negative electrode roll at the same time is solved; the problem of excessively high equipment cost is solved; equipment investment cost can be solved;and battery cell production cost can be decreased.

Description

Technical field [0001] The invention relates to the technical field of battery production, in particular to a method for preventing cross contamination of positive and negative electrode dust in a baking process. Background technique [0002] At present, in traditional battery production, in order to avoid the risk of cross-contamination of the positive and negative electrodes, the pole coil baking process is divided into a positive electrode area and a negative electrode area. The relatively isolated space and two sets of handling systems greatly increase the equipment cost. , Thereby increasing the production cost of the battery. [0003] Therefore, there is an urgent need for a method to prevent cross-contamination of the positive and negative electrodes during the baking process during battery production. Summary of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention...
