Lithium Battery Solder Joint and Appearance Inspection with SinceVision 3D Laser Profilers
Industry pain points and demands
Ensuring the quality of lithium battery solder joints and overall appearance is essential for maintaining performance, safety, and longevity. Defects in solder joints, such as cracks, voids, or uneven soldering, can result in poor electrical conductivity or even battery failure.
Similarly, surface irregularities like scratches or uneven finishes not only detract from the product's reliability but also undermine customer trust. However, traditional inspection methods often fall short in delivering the precision and speed necessary to meet the demands of modern lithium battery production, making advanced solutions indispensable.
SinceVision Solution: SR8060H and SRI7140 3D Laser Profilers
01High-Resolution Inspection: Detects minute solder joint defects and surface irregularities, ensuring compliance with quality standards.
02Fast Scanning Speed: Optimized for real-time inspection in high-throughput lithium battery production lines.
03Comprehensive Coverage: Dual profiler setup ensures complete inspection of solder joints and battery surfaces, enhancing product consistency. SinceVision SR8060H is used for top cover weld inspection, with an accuracy of up to 4μm, ensuring stable detection of welding defects. SinceVision SRI7140 is used for battery appearance inspection, with a detection accuracy of 0.01mm.
