Lithium Battery Industry - Positive Pole Guidance Assembly Inspection
In lithium battery manufacturing, the positive electrode pole must be accurately aligned and assembled. Any deviation, tilt, or contamination can lead to assembly failure, safety risks, or reduced battery performance. High-precision machine vision lighting is essential for capturing fine structures and ensuring stable detection.
Inspection Requirements
Identify the exact position of the positive electrode pole
Detect assembly alignment and ensure verticality
Check for defects such as scratches, deformation, or contamination
Ensure stable imaging under reflective metal surfaces
Lighting Solution
A customized low-angle ring light combined with coaxial illumination was used to highlight the metal texture and significantly improve contour and edge contrast. This lighting setup eliminates strong reflections and ensures consistent image quality across different production speeds.
Results & Benefits
Achieved ±0.05 mm positioning accuracy
Improved assembly pass rate by over 20%
Reduced false detections caused by glare
Ensured stable imaging on complex reflective surfaces
Supported long-term 24/7 automated operation
