电池极耳TAB焊接尺寸精度检测OA

Battery tab welding is an important process for welding thin copper foils and electrodes.Its welding quality will affect battery stability,reliability and service life.Its dimensional accuracy should be strictly controlled to ensure the consistency and stability of welding.The machine vision technology is used to realize the dimensional accuracy inspection of battery tab welding.Firstly,the camera is used to capture the image and filter the noise,then the HSV color space model is used for threshold segmentation,and the binary image is obtained.The zero area of the polar ear welding is found and the image is scanned pixel by pixel,and the size and accuracy of each size of the polar ear welding are obtained.Then the edge detection and Hough transform are performed on the binary image,the edge line segment is extracted,and the distance and accuracy between the core edge and the electrode are calculated.In this paper,the automatic detection of TAB welding dimension accuracy of battery pole ear is realized,which can improve the detection efficiency,ensure the inspection quality and reduce the labor intensity of workers.
