Detection system and method for zip fastener defects

Abstract

The invention discloses a detection system for zip fastener defects. The detection system comprises an image acquisition unit, wherein an output end of the image acquisition unit is connected with aninput end of an image processing and detection unit; the invention further discloses a detection method of the zip fastener defects; the detection method comprises the following steps: firstly, acquiring a gray scale image of a chain tooth to be detected; secondly, extracting a target chain tooth region and pre-processing the image; then carrying out quality detection on the chain tooth; finally,carrying out mass center distance detection on the chain tooth. The defect detection of a zip fastener is further completed through the introduced quality detection of the chain tooth, and the qualitydetection of the chain tooth is combined with the mass center distance detection of the chain tooth, so as to commonly realize comprehensive and accurate detection of the quality of the zip fastener.The method is simple to use and good in treatment effect, and can be used for rapidly and accurately judging whether the chain tooth has defects or not.

Description

technical field [0001] The invention belongs to the technical field of textile process detection, relates to a detection system for zipper defects, and also relates to a method for detecting defects by using the system. Background technique [0002] In recent years, with the vigorous development of my country's garment industry and textile industry, my country has become the largest zipper producer in the world, and the manufacturing technology of zipper has made great progress. However, in the production process of the zipper, due to the imperfect production process and the lack of corresponding testing equipment, more or less problems often occur, such as defects such as more teeth, less teeth, and incomplete chain teeth. [0003] At present, the domestic zipper detection technology is still in the stage of semi-automatic and manual detection. For the inspection of the quality of the finished zipper, the inspection method of visual inspection after sampling is generally u...
