Image inspection system apparatus
Metal Surface Inspection Device ①High Res-S ②High Res-HS
Inspection device (High-Res-2) was developed and started sales based on the new technology simultaneously inspecting ①Determination of a scratch and a line under oil ② Opposing corner and diagonal line ③Determination with burr .
New Technology
１．oil stained steel sheet
Dark field lighting effect
- ・It allows the inspection of the scratches without being affected by the stain.
- ・it turns the signal from the oil down, and also become capable of detect the longitudinal linear defect.
Installation of grid lighting at
a sensing environment
- 1、Grid lighting
- 2、LED diffused reflection lighting
2．Surface inspection for the electrical steel
Detection principle of hole and glitters
It detects such as normal draw scratches and line scratches, and also may discriminate holed defects and detect glitters on the surface of the electrical steel.
Inspection method for holes
Add LED lighting for the inspection for holes to the surface inspection part, and the holed defects will be detected and determined surely by the transmission type hole inspection,
as well as the holed defect discrimination function from the image processing.
Detect glitters
For the gathering defect of dots that are brightly luminescent generate on the surface of the electrical steel, detect one by one by light defect determination.
When more than designated number of dotted defects are generated within the designated area, determine them as abnormal denseness defects.
