[0004] The existing horn capacitor appearance detection device is a detection equipment based on a machine vision system. The principle of the capacitor appearance detection equipment is to use a visual detection system, convert the captured target into an image signal through a CCD industrial camera, transmit the image signal to a dedicated image processing system, convert the image signal into a digital signal according to pixel distribution and brightness, etc. The image system performs various operations on these signals to extract the characteristics of the target, and then controls the action of the on-site equipment according to the judgment result.

The existing detection device has a complex structure. The horn capacitor is placed in the sleeve and moves.
