Inspection of electrode sheets and metal foils | Strains, pinholes, edges
Electrode sheet and metal foil defect inspection | Striations, pinholes, coating edges
In the inspection of sheets coated with a film on metal foil, like electrode sheets, we look for streaks, pinholes, foreign objects, the position of the coating edge, and wrinkles or undulations in the foil. The presence or absence and position can be seen with a 2D line camera, but since the shiny foil and the dark coating appear in the same image, the visibility of defects changes depending on the lighting. When we want to see the height of protrusions and the shape of wrinkles in numerical form, we consider using 3D. [Key Points] - The shiny foil and dark coating are adjacent, so the appearance changes with lighting. - The position of the coating edge can be measured in 2D as the boundary between light and dark. - If you want to see the height of protrusions and the shape of wrinkles in numerical form, 3D should be added. *For detailed explanations, please refer to the technical notes in the related links and the downloadable materials.
