Description

Technical Field

[0001] The utility model relates to the technical field of glass detection, in particular to a glass defect visualization detection system. Background Art

[0002] With the rapid development of home appliances and construction technology, glass, as a key industrial material used in these fields, has a quality that directly impacts the aesthetics and lifespan of products. During the glass production process, defects can occur for a variety of reasons, primarily scratches, bubbles, and stains. Detecting defective glass during production can allow it to be returned to the factory for reprocessing, effectively reducing costs and improving product quality. Therefore, identifying glass defects is a pressing issue for glass manufacturers in both production quality control and product quality inspection. Currently, many glass manufacturers rely on workers to visually identify defects, a labor-intensive and time-consuming process, as well as challenging to detect. While automated glass defect detection equipment is commercially available, such equipment can only issue an alarm or mark the product when it detects defective glass. Even if it can screen out defective glass, workers still need to visually locate and confirm the corresponding defects on the glass. This method is inefficient, incomplete, and unintuitive. For most domestic glass manufacturers, developing highly efficient inspection equipment that can easily and intuitively identify defects is an urgent need. Utility Model Content
