Metal foil coating repairing mechanism

Abstract

The invention relates to the field of batteries, and discloses a metal foil coating repairing mechanism. The mechanism comprises a plurality of conveying rollers which are arranged between the outletend of coating equipment and final inspection equipment and used for conveying pole pieces; a first detection position, a first repair position and a first drying position are sequentially arranged onone surface of the pole pieces in the conveying direction; a second detection position, a second repair position and a second drying position are sequentially arranged on the other surface of the pole pieces in the conveying direction; the first detection position is located between the first detection position and the first drying position, the second detection position is located between the first detection position and the first drying position, the second repairing position is located at the downstream of the first repairing position, CCD high-speed cameras are arranged on the first detection position and the second detection position, spraying repairing devices are arranged on the first repairing position and the second repairing position, and dryers are arranged on the first dryingposition and the second drying position. The metal foil coating film repairing mechanism disclosed by the invention is used for repairing abnormal products with coating film missing, large color difference and poor uniformity, so that the overall defective product rate is greatly reduced.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a metal foil coating repair mechanism. Background technique [0002] Electrode technology has always played a very important role in the conductivity, battery life, cycle performance, etc. of the battery, so how to make a good electrode is the key. Adding the conductive film layer of the metal foil primer can better play the performance of the pole piece, not only can change the adhesion ability of the metal foil surface, but also play a role in other properties of the pole piece. Therefore, the quality of the primer conductive film layer is very important to a certain extent, the thickness of the film layer should be uniform, and the surface should be free from defects and damage. [0003] The traditional primer coating equipment is to complete the two-sided coating film at one time, and then after the size and surface inspection of the CCD high-speed camera, the abnormal products are ...
