Automatic Visual inspection machine for metal parts

Automatic Visual inspection machine for metal parts


Product Features

Automatic visual inspection system using AI
Determine bending of metal parts and detect presence or absence of scratches
Since it is not possible to detect bends and scratches at the same time with a single camera, we inspect each process separately.
When detecting bends in metal parts, a strong light is irradiated to intentionally generate halation on areas other than the bends, and only the bends are reflected and judged.

When it comes to detecting scratches, using red lighting makes the scratches stand out, so the idea is to visualize them using red lighting and use AI to detect the scratches.

Inspection

Detecting bends in metal parts was unstable and difficult.
Even when using normal lighting, the appearance of the image varies greatly depending on the degree of bending, making it difficult for AI to learn from the image.
By shining a strong light on it, we intentionally created halation, which wiped out all information other than the curve, allowing us to see only the curved part in the image.
If unnecessary information is omitted in this way, it will be easier for AI to learn, and it will be able to detect bends more stably.


When it comes to detecting scratches on metal parts, shining white light on metal tends to cause halation, and once halation occurs, the scratches become invisible.
However, by using red lighting for scratches on metal, the scratched area will appear black, making it easy to see that there is a scratch.
With images like this, it is possible to detect flaws using AI.


Inspection time

Bending detection of metal parts: 1 second
Scratch detection on metal parts: 1 second
