Appearance inspection – printed surface of batteries
Appearance inspection of battery surfaces to find flaws or dents was difficult because it was hard to differentiate between printing and defects. The LumiTrax™ function allows detection of just flaws and dents by cancelling 2D information such as printing.

Appearance inspection of battery housing
The inspection of outer cans for dents and scratches to maintain the strength of battery cells and modules is an important

Crystal resonator flaw inspection
Wrinkles on black sheets are often difficult to detect due to poor contrast. Shape images allow for inspection with wrinkles and foreign particles clearly extracted.
-
Differential gear appearance inspection
For the inspection of the sides of cylindrical targets such as gears for remaining black scales, stains, flaws, or dents, it was difficult to apply lighting evenly.

ECU sealant coat inspection
KEYENCE’s Pattern Projection Vision System uses 3D data to create contrast based solely on shape, rather than surface finish or colour.

Inspection for foreign particles in jelly after filling
When inspecting for dirt, hair, and other unacceptable contamination in a packaging process, flexible lighting is needed to detect the NG parts.

O ring burr inspection
Capturing the entirety of the part with a high-resolution camera enables inspections that can catch even the smallest burrs on O rings.

Wound coil appearance inspection
This is a wound coil appearance inspection example. Such inspections are sometimes unstable due to lighting reflections and variations in the colours with conventional lighting conditions.
