Minor defects—such as pinholes, explosion points, or protrusions—in power battery top covers can compromise sealing, leading to electrolyte leakage or short circuits, which severely impact battery performance and safety.
Manual inspection lacks consistency, resulting in production risks and customer complaints. Traditional algorithm-based vision systems still miss some small defects and struggle to accurately classify defect types. As a result, manual quality checks remain necessary, failing to achieve the intended goals of reducing labor costs and improving efficiency.
