Abstract

The invention discloses a zipper defect detection device based on vision. The zipper defect detection device comprises a conveying device, a cutting device, a vision system and a control system for connecting the conveying device, the cutting device and the vision system, the conveying device comprises a carrying platform and a transportation unit; the cutting device is arranged between the carrying platform and the transportation unit; the visual system comprises a first camera and a second camera which are used for acquiring images of the front side and the back side of the cloth tape, a third camera for acquiring images of zipper tooth parts, and a fourth camera and a fifth camera which are respectively used for acquiring images of two end parts of a finished zipper; the first camera and the second camera are respectively arranged on the upper side and the lower side of the carrying platform; the third camera is arranged between the carrying platform and the transportation unit; the fourth camera and the fifth camera are both arranged above the conveying unit. The cameras are arranged for different parts of the zipper respectively, the lighting sources meeting the conditions are arranged according to the parts, where the cameras obtain the images, of the cameras respectively, and the control system can judge the defects of the parts according to the images collected by the cameras respectively.

Description

technical field [0001] The invention relates to the technical field of product quality inspection, in particular to a vision-based zipper defect inspection device. Background technique [0002] Zippers are widely used in clothing, bags, tents and other daily necessities. Before the zipper leaves the factory, the quality inspection of the zipper is required to judge whether the zipper release is qualified. [0003] In the prior art, patent CN205317233U discloses a visual detection system for zippers. The system includes a plurality of detection devices 112 arranged along the guide rail 113, including light sources and cameras. The distance between the detection devices 112 can be adjusted. The system can At the same time, it detects the slider, top stop, bottom stop or square latch in the zipper. However, in this system, the structures of all detection devices 112 are the same. Since the slide fastener is composed of many parts (including cloth tape, chain teeth, upper and l...
