Description

Technical Field

[0001] The invention relates to battery appearance detection equipment and belongs to the field of battery production. Background Art

[0002] With China's current push for new energy, the lithium battery industry has experienced significant growth. This has led to increasingly stringent requirements for lithium battery production efficiency and quality. Therefore, it's crucial to strengthen effective control over the battery cell production process to improve production line efficiency and capacity. During battery production, appearance is a crucial component of battery quality inspection. Surface defects are directly linked to internal defects, which in turn impact battery safety and reliability. A thorough review of battery appearance can significantly mitigate potential issues, making visual inspection crucial. Currently, mainstream battery visual inspection relies on manual testing to identify obvious defects, such as bulging and scratches. However, this approach not only impacts overall production line efficiency but also significantly increases labor costs. Manual inspection also carries the risk of missed or false positives, necessitating the use of automated machinery to improve the accuracy and efficiency of visual inspection.
