In practical applications, the moving mechanism 1 carries and drives the material to move along the transmission direction, and the rotating mechanism 2 causes the material to rotate during its movement. (Reference) Figure 1 , 4 As shown, when materials are sequentially conveyed to the points of the collection device, the collection mechanism 4 synchronously drives the collection device 3 to move along the material conveying direction. The collection device 3 moves synchronously with the material to be inspected, and cleverly follows the side defects of the material to be inspected for all-round detection, so as to detect whether there are defects on the surface of the material to be inspected. It does not delay the transmission time, can realize online detection and batch detection, improve detection efficiency, facilitate the quick determination of the process that produces defective products, avoid material waste, reduce the difficulty of troubleshooting, and improve the quality of material detection.

[0058] refer to Figure 2 , 3 As shown, in this embodiment, the moving mechanism 1 includes at least two parallel material shafts 11 and a moving drive mechanism 12 for driving the material shafts 11 to move along the transmission direction. A receiving space 110 for placing materials is formed between the top ends of two adjacent material shafts 11. During the process of the moving drive mechanism 12 driving the material shafts 11, the rotating mechanism 2 drives the material shafts 11 to rotate so that the materials rotate. In actual application, the materials are placed in the receiving space 110, and the moving drive mechanism 12 drives the material shafts 11 to move. During the movement of the material shafts 11, the rotating mechanism 2 drives the material shafts 11 to rotate.

Since the material shaft 11 is rotatably mounted on the mounting seat 122, the rotation mechanism 2 drives the material shaft 11 to rotate during the movement of the material shaft 11 and the mounting seat 122. The bottom of the material is rubbed by the material shaft 11, thereby driving the material to rotate, which meets the material detection requirements at multiple angles.

Specifically, the transfer drive wheel 1232, the transfer driven wheel 1233, and the transfer driven wheel 1233 are all connected to the transfer drive wheel 1232 and the transfer driven wheel 1233. Two sets of wheels 1233 and conveyor 121 are symmetrically arranged at both ends of the material shaft 11. The two conveying drive wheels 1232 are connected by a rotating shaft to ensure synchronous rotation of the two conveying drive wheels 1232. The two ends of the material shaft 11 are respectively connected to the conveyor 121. The two conveyor 121 support the two ends of the material shaft 11 to ensure stable movement of the material shaft 11. During the movement of the material shaft 11, the self-rotation mechanism 2 drives the material shaft 11 to rotate. During the movement of the material, it is synchronously rubbed by the material shaft 11. The structure is cleverly arranged, which cleverly combines the material self-rotation process into the material transportation process, saving material transportation time and improving production quality.

During the movement of the material shaft 11, the material shaft driving mechanism 22 is used to drive the material shaft driving component 21 to move. Under the cooperation of the rubbing shaft protrusion 211 and the shaft groove 111, the material shaft 11 is passively rotated. The bottom of the material is rubbed by two adjacent material shafts 11, thereby causing the material to rotate. The material rotation is achieved during the movement of the material.

[0064] refer to Figure 8As shown, the drive mechanism 22 includes a drive motor 221, a drive wheel 222 driven by the drive motor 221, and a driven wheel 223. The material shaft drive 21 is provided with a belt section 212 connected to the rubbing shaft protrusion 211. The belt section 212 is connected to the drive wheel 222 and the driven wheel 223. In actual application, the drive motor 221 drives the drive wheel 222 to rotate, and under the action of the belt section 212, it drives the drive wheel 222 and the driven wheel 223 to rotate synchronously. The driving wheel 222 and the driven wheel 223 stably support the material shaft drive 21, facilitating the stable movement of the material shaft drive 21. The belt part 212 and the rubbing shaft protrusion 211 move synchronously. Under the action of the rubbing shaft protrusion 211 and the shaft groove 111, the bottom of the material is rubbed by two adjacent material shafts 11 to make the material rotate. Specifically, the number of mounting seats 122 is dozens to hundreds. The rubbing shaft protrusion 211 cooperates with the shaft groove 111 on at least dozens of material shafts 11, which facilitates the material shaft drive 21 to make a batch of material shafts 11 rotate synchronously, improving the material detection efficiency.

The bracket 43 supports the follow-up drive mechanism 41, improving its structural stability. During the rotation of the material driven by the moving mechanism 1, the acquisition device 3 selects the material to be inspected from the rotating material moving along the material transport direction. The follow-up drive mechanism 41 drives the acquisition device 3 to follow the material to be inspected, thereby collecting data from the surface of the material. The first light source 42 moves synchronously with the follow-up base 301, providing continuous and effective illumination to the material to be inspected. This facilitates providing the acquisition device 3 with an effective field of view, ensuring that the acquisition device 3 has complete and clear information about the material to be inspected, improving the acquisition quality of the acquisition device 3, enabling online monitoring, and improving material detection efficiency.

Specifically, a through hole can be provided on the movable mounting frame 51, and the locking part 54 is a locking screw. After the position of the acquisition device 3 is determined, the inner end of the locking part 54 is inserted into the through hole and tightly pressed against the outer side of the movable acquisition frame 52, thereby locking the movable acquisition frame 52 and the movable mounting frame 51.
