Insulator appearance inspection device

The utility model discloses an insulator appearance inspection device, and belongs to the technical field of insulator appearance inspection equipment. The detection elements comprise an upper detection element (11) arranged on the upper side of the conveying device, side detection elements (13) arranged on the two sides of the conveying device and a lower detection element (8) arranged on the lower side of the conveying device, and the signal output ends of the upper detection element (11), the lower detection element (8) and the two side detection elements (13) are all connected with the signal input end of the control device. The conveying device of the insulator appearance inspection device can convey an insulator to be detected, the upper detection element collects an image of the top of the insulator, the lower detection element collects an image of the bottom of the insulator, and the detection elements on the two sides collect images of the two sides of the insulator. The control device receives the c
