Dent detection on bolt screw


Date:

September 12, 22

This week topic is dents inspection on the bolt.

Some items that are difficult to detect with the standard spec AOI sorting machine.
however, some can be detected by changing the optical conditions.

 


The original optical conditions were limited to detect dents of 0.3 mm or more
in X and Y (threaded part).
We had to give up on detecting dents smaller than 0.3 mm.

This time, by using the 3 colors and large size (human face) of lights,
our detection level has considerably improved.
The new optical condition is capable of detecting even small dents (NG) that would stop a nut on the screw.
 
This customer exports most of its products.
However, they can't stop the inspection leakage.

The risk of NG flow-out in oversea would be very serious.
so in order to avoid the risk, reduce the ispection man-power cost,
and improve the reliability of the customer,
this customer is considering the AOI sorting even some parts, not all points.

Please feel free to contact us if any interest about AOI machine and our sorting service.
Let's make this week great one!
