Defective Edge Detection System Design for Long Bamboo Batten

To effectively and accurately detect edge defects in bamboos, a defective edge detection system for a long bamboo batten was designed in this study. There is a significant gap difference between the defective and intact edges of bamboo battens. Specifically, a large gap exists between the edge of a defective bamboo batten and a contact plate, whereas the gap is either very small or non-existent for a non-defective bamboo batten. The intensity of the light passing through the gap is detected using an optical fiber amplifier, and an infrared photoelectric switch positions the bamboo. The system can detect the four edges of multiple bamboo battens in real-time under the supervision of a master controller. The reliability of the system was verified through a series of physical experiments. This system can help in improving the production efficiency of bamboo plate processing enterprises, which is of considerable significance for the automatic production of bamboo products.
