A new inline process by Vitronic enables quality testing of lithium-ion batteries for electric vehicles. It can be used to detect particle contamination in battery cells as well as other defects. A high-resolution 16K line scan camera sensor simultaneously takes multiple images of the electrode foils from different angles, with different illumination. The detected particles are measured and automatically classified. Other defects can also be detected, such as position deviations, edge and cut defects, or surface properties of the electrodes that have changed due to transport.
Long Range Sensor for large Measuring Distances
The optoNCDT 1760-1000 long-range laser sensor by Micro-Epsilon also measures at distances of up to 2m with up to 7.5kHz.
