Description

A device for capturing images of defective zippers and its usage method Technical Field

[0001] This invention relates to the field of zipper inspection technology, specifically to a device for acquiring images of defective zippers and its usage method. Background Technology

[0002] Zippers are widely used in various clothing, bags, tents and other items to facilitate opening and closing. They are usually made of materials such as polyester fiber and nylon and are the main part of the zipper, which carries the chain teeth and connects the items. The width and strength of the zipper strap will vary depending on the application scenario. For example, the zipper strap for heavy winter coats is generally wider and stronger, while the zipper strap for light clothing is relatively narrower and softer.

[0003] Currently, the detection methods for defective zippers have gradually shifted from manual visual inspection to mechanical inspection methods. In particular, machine vision inspection has excellent objectivity, non-destructive nature, and high efficiency, making it more suitable for online inspection of zippers. The current work of collecting defective images for visual inspection in the zipper industry mainly relies on collection on the production line. This method is time-consuming and extends the project development cycle. Therefore, we have designed a zipper defective image acquisition device. Summary of the Invention
