[0003] In the battery production process, the battery cap is prone to various production defects, especially the front of the battery cap is prone to various quality defects
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 manual inspection, human emotions Influenced by experience and experience, it is easy to misdetect and omit detection, it is difficult to guarantee product quality, and it is difficult to meet the comprehensive testing requirements of large quantities of products

The invention discloses a battery cap front side vision detection method. The method comprises steps: a camera is calibrated, and the front side image of the battery cap is acquired through the camera; the front side image and the battery cap are subjected to size comparison, and a correction coefficient is acquired; through the front side image, the edge arc and the intermediate ring body of the battery cap front side are detected, and a disqualified battery cap is separated out; through the front side image, a vision defect area in the battery cap front side is detected, and a disqualified battery cap is separated out; through the front side image, a solder point defect area in the battery cap front side is detected, and a disqualified battery cap is separated out; and a battery cap which passes through the above detection steps is judged to be qualified. The front side of the battery cap is subjected to image acquisition through the camera, battery cap quality detection is realized through the image processing technology, the detection speed is quick, 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 front 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 front of the battery cap is prone to various quality defects. 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. Du...
