2results about How to "Improve rejection rate" patented technology

This invention relates to a debris removal system and method based on multimodal optical detection using air separation. The system includes a feed duct, a primary visual inspection and removal unit, a secondary laser inspection and removal unit arranged sequentially along the material conveying direction of the feed duct, a debris collection unit connected to the feed duct, and a noise reduction and maintenance unit that encloses noise-generating components. This invention forms a redundant and complementary detection system through dual-modal optical detection using both vision and laser. Primary visual inspection quickly removes debris with obvious optical characteristics, while secondary laser inspection identifies foreign objects of the same color in blind spots of visual inspection based on the physical properties of the material surface. This significantly improves the overall debris detection and removal rate, ensuring the high purity of the finished product.
