In the battery industry, defects like tearing at the welding edge, tab root, and underside are hard to detect due to occlusion and surface reflections, challenging traditional vision systems.
Customer Objectives
The customer requires defect detection for tab tearing on the front surface of a battery cell product, with a particular focus on identifying severe defects where the tearing length exceeds 2mm for both positive and negative electrodes. The inspection cycle time must be controlled within 1.1 seconds, demanding high-speed and high-precision detection capabilities.
