During the carbon fiber coagulation bath molding process, defects such as broken fibers, yarn twisting, tangling, lumps, and joints may occur. However, manual inspection is limited by the operator's speed and fatigue level, making it difficult to meet the requirements of high-speed production lines. This inspection system, based on machine vision technology, can perform real-time high-speed inspection, improving production efficiency. Furthermore, the system can operate stably for extended periods, ensuring continuous monitoring of the production process and promptly alerting personnel to handle any anomalies.
