If the UV roller coating process of the bamboo board 8 is unqualified, the first marker 52 is controlled to mark the unqualified bamboo board 8, and the unqualified bamboo board 8 is sorted to the second storage area.

[0066] In this embodiment, the frame 1 is a supporting structure below the first conveying assembly 2 and the second conveying assembly 3. The frame 1 can be obtained by welding steel pipes or locking aluminum alloy profiles. Furthermore, the first conveying assembly 2 and the second conveying assembly 3 are arranged on the frame 1. The first conveying assembly 2 includes a first conveyor belt 23, a first guide group 21 and a second guide group 22.

Optionally, the first storage area can be set at the output end of the second conveyor belt 32, and the second storage area can be set at other positions. Only when the UV roller coating process is unqualified, the sorting robot arm 61 will clamp the bamboo board 8 on the second conveyor belt 32 and move it to the second storage area. When the UV roller coating process is qualified, the bamboo board 8 can automatically enter the first storage area driven by the second conveyor belt 32.

[0071] In this embodiment, the determination of the UV coating process of the bamboo board 8 is completed by the control unit 7. Further, the control unit 7 can be integrated into a console separately, and the control unit 7 is used to determine whether the UV coating process of the bamboo board 8 is qualified according to the image information of the current bamboo board 8. If the UV coating process of the bamboo board 8 is unqualified, the first marker 52 is controlled to mark the unqualified bamboo board 8, and the unqualified bamboo board 8 is sorted to the second storage area. It should be noted that the detailed logical judgment content of the control unit 7 can be understood by referring to the detection method described later.

[0072] This embodiment diverts the bamboo boards 8, and performs comprehensive inspections on the bamboo boards 8 in turn, captures the image information of the bamboo boards 8, and can promptly discover and handle unqualified bamboo boards 8, thereby improving product quality management efficiency, reducing the number of unqualified products, and improving production efficiency and product quality.
