Magnetic Ring Outside Inspection Program-Electronic Industry-Specialized in visual imaging solutions_Non-standard optical customization-Dongguan Chuangshi Automation Technology Co., Ltd

Industry background

Magnetic rings, usually made of soft magnetic materials such as iron, nickel and cobalt, are essential components in electronic and electrical equipment. Magnetic rings generate magnetic field and transfer magnetic energy through a closed magnetic path. The quality directly determines the performance of the equipment. At present, the production enterprises for the outer wall of the magnetic ring in the production process may produce disconnection, multi-glue, cracks, bruises and other processing defects detection mainly rely on the human eye. Artificial detection method of judgment standards vary from person to person, different individual detection results may not be the same. Detection efficiency and reliability is not high. Enterprises are in urgent need of a new inspection program to complete the quality screening of magnetic rings before leaving the factory. After many comparisons, the customer finally chose Chuangshi Automation magnetic ring outer wall appearance inspection program.

Advantages of the plan

In the whole set of magnetic ring outer wall appearance inspection program. Adopting the surface array method, according to the size of the sample will be 50MM Chuangshi FA lens and camera tilted to a certain size, once can shoot the entire ring 1/3 of the outer wall. In the light source part, choose the ring shadowless light source from the product above the irradiation, the background selection of white background, the combination of the two to highlight the contrast of defects, to achieve the purpose of detection.

This program can be continuous and uninterrupted detection!
