The control device 6 will receive the barcode information. Since none of the first and second conveying track mechanisms 31, 31' carry the plate 1, therefore, the sensing element 36 of the first and second conveying track mechanisms 31, 31' will not generate a sensing signal, the The control device 6 can then determine that the first conveying track mechanism 31 and the second conveying track mechanism 31 ′ do not carry the plate 1.

Referring to Figure 8, Figure 10, Figure 11 and Figure 12, then, the control device 6 controls The transfer mechanism 42 that manufactures the feeding and transfer device 4 conveys the plate 1 to the first conveying rail mechanism 31. When the conveying belts 322 (as shown in FIG. 5) and 332 of the first conveying track mechanism 31 move the plate 1 to a position above the sensing element 36, the sensing element 36 generates the sensing signal.

In this embodiment, the The laser 52 is used to engrave product information such as bar codes. Of course, the laser 52 can also engrave product information such as a two-dimensional code, and is not limited to the aforementioned barcode.

During the process of engraving the plate 1 by the laser engraving device 5, the transfer mechanism 42 of the feeding transfer device 4 will be at the first feeding position to continue to accept the feeding side 21 (as shown in FIG. 1 Shown) another input of this board 1. Since the control device 6 judges that the first conveying track mechanism 31 carries the plate 1 through the sensing element 36 (as shown in FIG. 9) of the first conveying track mechanism 31, the control device 6 will control the feeding The driving mechanism 41 of the transfer device 4 drives the transfer mechanism 42 to move along the second transverse direction Y to the second feeding position shown in FIG. 14.

When the laser engraving device 5 finishes engraving the barcode, the camera 53 captures the engraved barcode image and generates corresponding barcode information. The control device 6 will receive the barcode information. The control device 6 sends the barcode information received by the automatic code reader 7 and the barcode information received by the camera 53 to a field information integration system (SFIS) together, so that the field information integration system The aforementioned barcode information is bound to facilitate the traceability of the product source of the panel 1.

Referring to Figures 8, 13 and 14, after the laser engraving device 5 completes the engraving of the plate 1 carried by the first conveying track mechanism 31, the control device 6 controls the first conveying track mechanism 31 to complete the engraving The plate 1 is conveyed to the discharging transfer device 4'on the transfer mechanism 42 located at the first material receiving position. On the other hand, the control device 6 controls the transfer mechanism 42 of the feeding transfer device 4 to transport another plate 1 To the second conveying track mechanism 31'.

The transfer mechanism 42 of the discharging transfer device 4'will then output the carried board 1 to the next workstation via the discharging side 22 (as shown in Fig. 1). The control device 6 controls the moving mechanism 51 to drive the laser 52 and the camera 53 to move below the other plate 1 carried by the second conveying track mechanism 31', so that the mine is moved by the aforementioned positioning method. The laser 52 is positioned at the second engraving position as shown in FIG. 14, so that the laser 52 can perform laser engraving on the position to be engraved on the bottom surface 11 of the other plate 1.

During the process of engraving the plate 1 by the laser engraving device 5, the control device 6 determines through the sensing element 36 of the second conveying track mechanism 31' that the second conveying track mechanism 31' carries the plate 1, so , The control device 6 will control the driving mechanism 41 of the feeding transfer device 4 to drive the transfer mechanism 42 to return to the first feeding position shown in FIG. 15 to continue to accept the feeding side 21 (such as Shown in Figure 1) another input of the panel 1. In addition, the control device 6 controls the driving mechanism 41 of the discharging transfer device 4'to drive the transfer mechanism 42 to move along the second transverse direction Y to the second material receiving position shown in FIG. 15.

It should be noted that the other panel 1 that is input later will also be read by the automatic barcode reader 7 on the top surface 12 according to the aforementioned method, and the camera 53 will capture the engraved bottom surface 11 Barcode image, so I won’t repeat it here.

Referring to Figures 8 and 15, the second laser engraving device 5 is engraved to complete the second After conveying the plate 1 carried by the rail mechanism 31', the control device 6 controls the second conveying rail mechanism 31' to transport the carved plate 1 to the discharge transfer device 4'which is located in the first On the transfer mechanism 42 at the second material-bearing position. On the other hand, the control device 6 controls the transfer mechanism 42 of the feeding transfer device 4 to transport another plate 1 to the first conveying rail mechanism 31.

By repeating the foregoing operation mode, the dual-track laser engraving machine 200 can automatically and continuously perform laser engraving on the input panel 1.

In summary, the dual-track laser engraving machine 200 of the present embodiment uses the first conveying track mechanism 31 and the second conveying track mechanism 31' of the conveying device 3, the feeding and transferring device 4, and The design of the discharging transfer device 4'can quickly and smoothly convey the plate 1 to the positioning, which can save the time of feeding, positioning and discharging the plate 1 and improve the conveying efficiency. The manner in which the first conveying track mechanism 31 and the second conveying track mechanism 31' cooperate with each other to convey the plate 1 can facilitate rapid and continuous laser engraving operations, thereby realizing high-speed marking. The laser 52 of the laser engraving device 5 can move between the first engraving position and the second engraving position, so that the dual-track laser engraving machine 200 can use a single laser 52 Laser engraving the plate 1 carried by the first and second conveying track mechanisms 31, 31' at different positions can save the manufacturing cost of the dual-track laser engraving machine 200. As a result, the dual-track laser engraving machine 200 can automatically and continuously perform laser engraving on the input panel 1, which can effectively improve the engraving speed, efficiency and yield, and can overcome the problems caused by manual labeling. defect. this In addition, the laser engraving device 5 is arranged under the conveying device 3 and the laser 52 is engraved on the bottom surface 11 of the plate 1 from bottom to top, so that the plate 1 is input to the dual-track mine After the engraving machine 200, laser engraving can be carried out without turning over, thereby avoiding damage to the electronic parts arranged on the top surface 12 of the plate 1 during the turning process, so it can indeed achieve the new cost The purpose.
