Description

Technical Field

[0001] The present invention relates to the technical field of zipper detection, and in particular to a device for collecting images of defective zippers and a method for using the device. Background Art

[0002] Zippers are a type of connector that is widely used on various clothing, bags, tents and other items for easy opening and closing. They are usually woven from polyester, nylon and other materials. They are the main part of the zipper and carry the chain teeth and connect items. The width and strength of the chain will vary depending on the application scenario. For example, zipper chains used for heavy winter coats are generally wider and stronger, while those used for light clothing are relatively narrow and softer.

[0003] At present, the detection method for defective zippers has gradually shifted from manual visual inspection to mechanical inspection. In particular, machine vision inspection has excellent objectivity, non-destructiveness and high efficiency, and is more suitable for online inspection of zippers.
