Problems solved by technology

[0002] During the production and preparation process, various defects of capacitors include: scratches on lead rods, cracked sleeves, blisters, scratches, scratches, exposed aluminum shells, expansion, reverse rubber plugs, rubber plug protrusions, tilting, pill sticks Problems such as exposure, long casing, turned-up casing, poor sealing, bad casing cutting, rubber plug damage, dirty packaging, etc.

There are only a few applications of machine vision technology in the field of capacitance detection. For example, Chinese patent CN102401800A discloses a high-voltage ceramic capacitor welding quality online inspection equipment based on machine vision, but this equipment cannot integrate the defect detection of the above-mentioned capacitors into one equipment system. In particular, the packaging function and the detection system are integrated into one equipment system to achieve

In the existing technology, there are still secondary damages caused by handling and discharging after capacitance detection, and the technical problems of low single-capacitance detection efficiency
