Character Detection in Wire Drawing Process

Case Explanation

It is necessary to detect the characters on the lid of the thermos cup because the surface of the product parts is brushed. When lighting, the light irradiation in different directions will show different effects.

However, the direction of incoming materials during parts inspection cannot be guaranteed on site during inspection, so we need to use a light source that can produce the same effect at any angle. In the same ordinary light source, the sample will produce two different lighting effects.

After using a special light source developed by ourselves, the incoming parts can produce the same effect in any direction.


Test Summary

·Light character detection.
·Due to the drawing process on the surface of the part, different effects of light will appear when lighting.
·Ensure that parts have consistent effects in different directions.
