The surface defects of particleboard include oil stains, scratches, pits, debris, large shavings, glue spots, etc. The traditional defect detection method is to arrange staff to manually inspect the particleboard and judge whether there are defects by naked eyes and touch. However, this detection method is inefficient and has high work intensity. As the working hours increase, the staff will become tired and prone to problems such as missing inspections and false inspections.

[0004] In response to the above problems, the invention with patent publication number CN114527141A discloses a particleboard surface defect collection system. The system includes several groups of collection units, light source controllers, collection cards, board grading controllers, servers and on-site PLCs that are spaced near the conveyor belt that transmits the particleboard; the collection device includes a camera, a light source, a photoelectric switch, an encoder, and an encoder signal generator. The present invention adds hardware equipment such as sensors, cameras, light sources, and servers to the particleboard production site to collect pictures of the particleboard during the production process, and through machine vision recognition, it is determined whether the current particleboard has defects, and the particleboard is automatically transported to the desired location after defect grading.

[0005] The system transmits by setting two conveyor belts at intervals, and setting cameras up and down between the two conveyor belts (the patent document Figure 2 As shown in the figure, however, the particle board is always placed flat during the inspection. When the particle board moves from one conveyor belt to two conveyor belts, its two ends are respectively in contact with the two conveyor belts, blocking the camera's shooting.

The inspection of the bottom surface is not thorough, and there is a gap between the two conveyor belts, which increases the floor space of the overall system equipment and aggravates the space pressure of the factory.
