Description
technical field [0001] The invention relates to the field of solder joint defect detection, in particular to a visual online detection method for lithium battery tab laser solder joints. Background technique [0002] At present, with the development of my country's industry, welding technology has become an indispensable processing technology in manufacturing and industry, but in the welding process, due to the complex and changeable external production environment, the quality of solder joints is likely to vary. When detecting solder joints with ear laser, the traditional method is to use manual re-inspection to detect solder joints, but manual re-inspection is not only easy to cause misjudgment, but also the re-inspection efficiency is not high, which has caused a great impact on production resources and human resources. Serious waste. Therefore, it is urgent to propose a visual online detection method for lithium battery tab laser solder joints, which is used to solve the p...
