Description

Technical Field

[0001] The utility model relates to the field of grinding equipment, in particular to a burr detection and grinding equipment for lithium battery electrodes. Background Technique

[0002] The electrodes of lithium batteries are important components that constitute the electrochemical reactions of lithium batteries. They are divided into cathode plates (negative electrodes) and anode plates (positive electrodes), which are responsible for the positive and negative reactions of the battery respectively. During the battery processing, a small amount of burrs will be generated on the positive and negative electrodes of lithium-ion soft-packaged batteries. If these burrs are too large, they will pierce the separator between the positive and negative plates, thus forming a short circuit, and in severe cases, even cause battery safety accidents such as explosion. Therefore, during the production of lithium batteries, the length of burrs on the lithium battery electrodes must be strictly controlled.

[0003] However, most of the existing lithium battery electrode detections are carried out by sampling detection under a microscope. Such detections have the problems of large manual measurement labor intensity, and are extremely prone to burr missed detection and misdetection, which will affect the qualification rate of product production.
