Description

Technical Field

[0001] This utility model relates to the field of automatic optical inspection technology, specifically to an automatic inspection device for the appearance of mobile phone batteries. Background Technology

[0002] Defects in the appearance of mobile phone batteries not only affect the product's aesthetics but can also seriously impact battery performance and safety. Therefore, effective detection of appearance defects in mobile phone batteries is a crucial step in ensuring product quality and user safety.

[0003] Battery surface defects, such as scratches, cracks, dents, and contaminants, can affect battery performance and safety. Undetected surface defects may lead to battery malfunctions during use or even safety accidents. Effective surface inspection allows for the timely detection and repair of defects during production, ensuring that every battery leaving the factory meets quality standards.

[0004] Currently, the main methods for inspecting mobile phone battery casings in the industry are: 1. Inspection under artificial sunlight from multiple angles. This method is wasteful of manpower and resources, inefficient, and prone to misjudgment due to subjective human judgment; 2. CCD detection of battery appearance defects. However, CCDs cannot automatically focus, are inconvenient to maintain, and have low compatibility with products of different sizes. Therefore, we propose an automatic inspection device for mobile phone battery appearance to solve the above problems. Utility Model Content
