All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0031] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] As Figure 1 and Figure 2 and Figure 3 shown, it includes a driving component 1, a transportation component 2 and a laser machine 3. The driving component 1 is used to drive the laser machine 3 to move, the transportation component 2 is used to convey products, and the laser machine 3 is used to laser QR codes on the products.

[0033] The driving component 1 includes a first linear module 11 and a gantry 12. The first linear module 11 is arranged on the gantry 12, and the laser machine 3 is slidably arranged on the driving end of the first linear module 11. The first linear module 11 can drive the laser machine 3 to move back and forth.

[0034] The transportation component 2 includes a bottom plate 21 and a second linear module 22. The second linear module 22 is arranged on the bottom plate 21. A bearing plate 23 is arranged at the driving end of the second linear module 22. The product is placed on the bearing plate 23, and the second linear module 22 drives the bearing plate 23 to move back and forth.

[0035] A guide plate 4 is arranged on the laser machine 3, and a jet head 5 is arranged on the guide plate 4. The jet head 5 is externally connected to an inert gas source, and the jet head 5 sprays nitrogen to prevent oxidation of the laser area.

[0036] The bearing plate 23 has two states: being away from and staying in the laser area of the laser machine 3. Driven by the second linear module 22, when the bearing plate 23 moves into the laser area of the laser machine 3 and a two-dimensional code is formed on the product, that is, when starting to laser, high temperature will be generated. In this way, the high-temperature area on the workpiece is prone to oxidation. The jet head 5 is turned on, and the jet head 5 sprays nitrogen onto the area where the two-dimensional code is located on the product to prevent the area where the two-dimensional code is located on the product from being oxidized.

[0037] After the product is protected from oxidation to the target, the jet head 5 is turned off. Driven by the second linear module 22, the bearing plate 23 resets to replace the workpiece to be laser.

[0038] The driving component 1 further includes a first slide rail 13 and a first slider 14. The first slide rail 13 is arranged in parallel with the first linear module 11. The first slider 14 is slidably arranged on the first slide rail 13. The bottom of the laser machine 3 is connected to the first slider 14, and the laser machine 3 is simultaneously connected to the first slider 14 and the first linear module 11, so that the laser machine 3 is more stable during the moving process.

[0039] Furthermore, a sliding seat 15 is slidably arranged on the first linear module 11, and the laser machine 3 is arranged on the sliding seat 15. The laser machine 3 is simultaneously connected to the first slider 14.

[0040] A load-carrying component 6 is slidably arranged on the second linear module 22. The load-carrying component 6 includes a pallet 61 and a third linear module 63. The second linear module 22 drives the load-carrying component 6 to move. The pallet 61 is slidably arranged on the second linear module 22, and the second linear module 22 drives the pallet 61 to move. The third linear module 63 is arranged on the pallet 61, and a bearing plate 23 is arranged on the third linear module 63. The driving direction of the third linear module 63 is perpendicular to the driving direction of the second linear module 22. In this way, under the combined action of the second linear module 22 and the third linear module 63, the bearing plate 23 can move on a plane. When the bearing plate 23 moves to the laser area of the laser machine 3, an error will occur because the position of the workpiece placed on the bearing plate 23 is different each time. Therefore, through the combined drive of the second linear module 22 and the third linear module 63, the laser area to be laser of the workpiece on the bearing plate 23 is aligned with the laser area of the laser machine 3.

[0041] A vision camera 7 is also arranged on the laser machine 3. The scanning end of the vision camera 7 is aligned with the laser area of the laser machine 3. The vision camera 7 can identify whether the laser area on the workpiece is within the set range through scanning. In addition, the vision camera 7 can identify whether the two-dimensional code after laser forming is valid through scanning.

[0042] Furthermore, a vertical rod 8 is also arranged on the laser machine 3. The vision camera 7 is rotatably arranged on the vertical rod 8. According to workpieces of different shapes and different laser areas, the alignment position of the scanning end of the vision camera 7 is adjusted.

[0043] Such as Figure 4 and Figure 5 As shown, the load-carrying component 6 further includes a second slide rail 62 and a second slider 64. The second slide rail 62 is arranged in parallel with the third linear module 63. The second slider 64 is slidably arranged on the second slide rail 62. The bearing plate 23 is connected to the second slider 64. The bearing plate 23 is simultaneously connected to the second slider 64 and the third linear module 63, and the movement of the bearing plate 23 is more stable.

[0044] A plurality of bumps 24 are arranged on the upper surface of the bearing plate 23. The heights of the bumps 24 are not consistent. Because there may be impurities on the workpiece and the lower surface of the workpiece is uneven, the use of a plurality of bumps 24 with different heights can keep the workpiece balanced.

[0045] A groove 25 is also arranged on the bearing plate 23. The groove 25 extends to the outer edge of the bearing plate 23. It is convenient to take out or place the workpiece from the groove 25.

[0046] Furthermore, the first linear module 11 drives the laser machine 3 to move back and forth. A plurality of conveying components 2 are arranged in parallel. Correspondingly, the number of the carrier plates 23 and the carrying components 6 is set to match the number of the conveying components 2. After the workpiece QR code is laser-formed on one of the carrier plates 23, the laser machine 3 moves above the next carrier plate 23, and so on in a cycle.

It is not intended to limit the protection scope of the present invention.
