Abstract

The invention provides a welding spot detection device and method for a cylindrical battery cap. The device comprises an image obtaining module which is used for obtaining a welding spot image of the cylindrical battery cap; a welding spot acquisition module which is used for detecting welding spots in the welding spot image based on a multi-feature welding spot template to obtain welding spot quality information; a matching module which is used for matching the welding spot quality information with welding spot standard information of a standard welding spot template corresponding to an actual production drawing, and sending a corresponding result to a feedback module when the welding spot quality information is not matched with the welding spot standard information; and the feedback module which is used for feeding back the result to a user terminal. The method can solve the problem that the number of welding spots which are complex in supplied material and excessively different from a template is not matched completely when the welding spots are matched.

Description

technical field [0001] The invention relates to the technical field of 3C manufacturing in the lithium battery industry, in particular to a welding spot detection device for a cylindrical battery cap. Background technique [0002] At present, with the continuous development of society and the continuous advancement of science and technology, mechanical automation production has become a development trend, and gradually replaces traditional manual labor, injecting new power sources for the sustainable development of enterprises. In the process of battery production and manufacturing, it is also necessary to promote technological transformation, vigorously develop mechanical automation production, and realize the sustainable development of battery manufacturing enterprises. The traditional detection is to match multiple solder joints with one template. Due to the complex production environment, the solder joints are diverse. Compared with the previous method, multi-template ma...
