Various high-tech innovation in the field of industrial automation, vision inspection technology with its fast, real-time, accurate collection and processing information advantages, has gradually become an indispensable technical tool and means to enhance the competitiveness of enterprises in the automation industry, its application areas are becoming more and more extensive, and has also been favored by the textile accessories industry.

　　The quality of textiles and their auxiliary materials is the lifeblood of the survival of textile manufacturers. As an extremely important part of the production, quality inspection is essential for effective quality management to find out the problems of product quality, reduce the defective rate and improve the quality of products. At present, most of the domestic textile enterprises have adopted spinning machines with a high degree of automation, but their product surface quality inspection has been stuck in the traditional manual inspection stage due to the lack of visual inspection and testing equipment to match them, and the inspection workers look for surface defects of textiles and their accessories with their naked eyes by referring to the given standards. The manual inspection method is prone to visual fatigue, labor intensity, low inspection efficiency, and the inspection results are susceptible to the influence of human subjective factors, false detection rate, high leakage rate and other shortcomings.

　　Machine vision inspection is a comprehensive science and technology that integrates optics, computer science, mechanical science, and physics, and is used in manufacturing inspection and other industrial fields to ensure product quality, control production processes, and sense the environment. Machine vision system is the target to be taken into the image signal, transmitted to the special image processing system, according to the pixel distribution and brightness, color and other information, into a digital signal; image system for these signals to perform a variety of operations to extract the characteristics of the target, and then according to the discriminatory results to control the site equipment action.

　　Machine vision inspection technology in the textile accessories industry applications.

　　1. textile inspection: can be for cloth, such as non-woven fabrics, towels and other surface defects detection, such as holes, stains, loose edges, unsealed edges, threads, trademarks and other types of defects.

　　2. Button detection: can measure the length, height, outer diameter and other dimensions of various types of metal and resin buttons, as well as detect surface defects such as bad plating, crushing, deformation, scratches and breakage.

　　3. zipper inspection: front and back chain teeth inspection for all types of metal, plastic and nylon zippers, detection of missing chain teeth, detection of chain teeth crushing and scratching defects, etc.

　　The introduction of machine vision inspection technology makes the textile production line into a fast, real-time, accurate and efficient assembly line, which can greatly improve production efficiency. The use of machine vision inspection equipment instead of the human eye to complete monitoring, measurement and judgment, with non-contact, repeatable, reliable, high precision, continuity, high efficiency, flexibility and many other application advantages.
