[0104] Similarly, after the sixth roller 323 supports the tray 510, the eighth driving unit 324 drives the sixth roller 323 to rotate, so that the tray 510 can move along the second direction through the friction between the sixth roller 323 and the tray 510, and the tray 510 can be stably transported along the second direction.

[0105] Specifically, the specific structure of the eighth driving unit 324 may refer to the first driving unit 221 , and will not be described again here.

[0106] Appropriate reference Figure 2 In some embodiments of the present application, the tray 510 is provided with at least three.

[0107] After at least three trays 510 are provided, at least one tray 510 can be used for loading, at least one tray 510 can be used for processing, and at least one tray 510 can be used for unloading and sorting. Loading, processing and unloading and sorting can be carried out simultaneously, which is beneficial to improving production efficiency.

[0108] Specifically, the number of the trays 510 may be three, four, five or other numbers.

[0109] Reference Figure 5 The laser processing device according to the second embodiment of the present application includes a conveying device and a laser device 600. The laser device 600 is used to generate laser to process the workpiece 520 on the tray 510 in the first conveying channel 211.

[0110] The laser processing equipment according to the embodiment of the present application has at least the following beneficial effects: by using the above-mentioned conveying device, the processing rhythm can be matched with the loading rhythm, and the processing rhythm can be matched with the unloading rhythm, which is beneficial to improving the production efficiency of the laser processing equipment.

[0111] Specifically, the laser processing equipment may be one of laser cutting equipment, laser drilling equipment, laser welding equipment and laser marking equipment.

[0112] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
