The invention discloses a battery cover reverse side visual inspection method. The battery cover reverse side visual inspection method comprises the steps that reverse side images of battery covers are obtained through a camera; and the reverse side images are compared with battery covers to obtain correction coefficients, the bottom disc wrapping edges on the reverse sides of the battery covers are inspected, the unqualified battery covers are separated out, the scratch areas on the reverse sides of the battery covers are inspected, the unqualified battery covers are separated out, the welded breakdown areas on the reverse sides of the battery covers are inspected, the unqualified battery covers are separated out, the porous mixing areas on the reverse sides of the battery covers are inspected, and the unqualified battery covers are separated out. The battery covers passing inspection of the steps are judged to be qualified. According to the battery cover reverse side visual inspection method, image collection is conducted on the reverse sides of the battery covers through the camera, the bottom disc wrapping edges, the scratch areas, the welded breakdown areas and the porous mixing areas on the reverse sides of the battery covers are inspected and judged to be qualified or not, quality inspection of the battery covers is achieved through the image processing technology, the inspection speed is high, and the accuracy is high.
Description
technical field [0001] The invention relates to the technical field of batteries, and more specifically relates to a method for visually detecting the reverse side of a battery cap. Background technique [0002] The battery cap is the core component of the battery. It not only serves as a conductive electrode, but also provides battery sealing and safety valves. Its quality directly affects the service life of the battery and personal safety. Therefore, it is necessary to check the battery cap before installing the battery. Strict appearance inspection. [0003] During the battery production process, the battery cap is prone to various production defects, especially the reverse side of the battery cap. With the continuous development of the new energy industry, the quality requirements for battery caps are getting higher and higher. However, most battery manufacturers currently use manual inspection methods to inspect the appearance of battery caps. Due to the slow speed of...
