Description

Technical Field

[0002] With the development of modern society, mobile devices such as mobile phones, camcorders, laptops, portable DVD players, and digital cameras have become increasingly widely used, and correspondingly, battery quality standards are becoming increasingly stringent. During the battery production process, not only are the battery's external dimensions inspected, but also the barcode position, the cell tab margins, and the tab package slot marks, among other things. Among existing patents, Chinese patent application number 202221925669.8 discloses a device for detecting battery cell tab weld marks. The device comprises two light sources, spaced apart and horizontally movable, for illuminating the positive and negative tabs of a battery cell. The camera is positioned above the two light sources to capture images of the battery cell. The processor, connected to the camera, detects the weld marks on the cell tabs from the received images to obtain test results. The patent document uses a light source pointing vertically downward to capture the cell tabs. However, the aluminum-plastic film of the cell easily reflects light, resulting in unclear images and difficulty ensuring accurate detection. Manual inspection is also required, leading to low detection efficiency. Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content
