The wire crimp terminal pins shall be sent to the electroplating section after stamping.
Similar to the stamping stage, problems such as pin distortion, breakage or deformation will also occur when the stamped pins are fed into the electroplating equipment.
For most machine vision system suppliers, many quality defects in electroplating process are still forbidden zones for detection systems.
Custom crimp terminal manufacturers hope that the inspection system can detect various inconsistent defects such as fine scratches and pinholes on the electroplated surfaces of connector pins.
These defects can be easily identified on other products (such as aluminum can bottoms or other relatively flat surfaces).
Due to the irregular and angular surface design of most electronic connectors, it is difficult for the visual inspection system to obtain the images needed to identify these minor defects.
This is a very difficult task for vision systems using black-and-white cameras, because the image gray levels of different metal coatings are virtually the same.
Although the camera of color vision system can successfully distinguish these different metal coatings, the problem of lighting difficulty still exists due to the irregular angle and the reflection effect of the coating surface.
