The Edge-Vision-4.0-CURTAIN machine-vision system from Hammer-IMS is able to detect pinholes and other anomalies in battery film/electrode coating at a scale of 10 micrometers. Utilization of 3x 12k resolution camera modules allow for scans from the production every 125 microseconds, or in other words, 8000 scans per second. This translates to a line speed of 0.08 m/second or about 5 meters per minute for quality scans to be achieved. This 10 micrometer oversampling capture at that rate of speed minimizes pixel discretization errors, which is the process of converting continuous data into a digital form, enabling us to detect anomalies as tiny as 50x50 micrometers more accurately. In contrast, systems utilizing lower-resolution cameras will inherently introduce more discretization, rendering them less effective at identifying such minuscule defects.
