Description

Technical Field

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

[0002] During the production process, fabrics are prone to defects or flaws due to environmental factors or raw material influences. These defects may include variations in fabric density, broken threads, streaks, misaligned yarns, spots, patches, damage, and uneven dyeing. Therefore, to provide higher quality fabrics, manual inspection is typically performed. In this manual inspection, the fabric is placed on a conveyor belt and observed visually for defects, which are then marked with labels. However, this method of visual inspection is susceptible to eye fatigue and misjudgment after prolonged observation, leading to a decrease in the fabric defect detection rate. Furthermore, existing methods using fixed fabric are ineffective for defect detection. Therefore, we have developed a fabric defect detection device. Utility Model Content
