Use Case: Battery Inspection
- Casing Inspection: Typical battery casing defects such as scratches, dents, cracks, and stains, are difficult to detect using conventional machine vision: not only are the defects difficult to capture because of the reflective nature of the casing surfaces, but the threshold for defects is also difficult to quantify.
With SaigeVision® Segmentation, such external surface defects can be detected and identified accurately and quickly.
- Tab Inspection: Battery tabs, which are made of a variety of metals (aluminum, copper, nickel), are thin, soft, and easily damaged. Common defects include scratches, bumps, holes, and dirt. All defects must be identified and eliminated prior to soldering, since a damaged tab can significantly degrade battery performance. Low-quality soldering can also cause downstream defects such as burns, hits, and missing balls.
With SaigeVision® Segmentation, tab defects can be identified accurately and quickly.
- X-Ray Inspection: Checking the alignment of the positive and negative electrodes inside a battery, determining whether there are a correct number of electrodes, and identifying poor-quality welds are critical steps in battery inspection. X-ray inspection is the preferred non-invasive method for battery internal inspection, but X-ray images can be noisy and highly susceptible to environmental variables.
With SaigeVision® Super-Resolution and Segmentation, battery internal inspection using X-rays can be conducted accurately and reliably.
