Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting printing equipment technology, specifically a laser coding anti-counterfeiting printing equipment. Background Technology

[0002] Laser marking involves focusing a laser beam with extremely high energy density onto the surface of the object being marked. This vaporizes the surface material through burning and then shifts the laser beam to create precise patterns or text, thus forming a certain anti-counterfeiting label on the product surface.

[0003] After production, existing metal parts often require laser marking to engrave anti-counterfeiting labels on the metal surface. Some products require laser marking on both the front and back. However, since the direction of the laser is fixed, after marking one side of the metal part with laser, the part needs to be manually flipped over and marked a second time. This process is tedious and takes up a certain amount of time. Utility Model Content

[0004] The purpose of this invention is to provide a laser coding anti-counterfeiting printing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser coding anti-counterfeiting printing device, comprising a first conveyor table, a second conveyor table mounted on the upper end of the first conveyor table, the length of the first conveyor table being greater than the length of the second conveyor table, a first side plate mounted on each side of the first conveyor table, a second side plate mounted on each side of the second conveyor table, a telescopic plate mounted on the inner side of each of the first and second side plates, a laser head mounted on the lower end of each telescopic plate, a lifting plate mounted between the first and second side plates and located outside the first conveyor table, a rotating shaft rotatably connecting the two lifting plates, a driving device connected to one end of the rotating shaft, and an electromagnet mounted at the center of the surface of the rotating shaft.

[0006] Preferably, a groove is provided on the inner side of both the first side plate and the second side plate, and a threaded rod is rotatably connected inside the groove. One end of the threaded rod is connected to a driving device, and a movable plate is threadedly connected to the surface of the threaded rod. The front end of the movable plate is connected to one end of the telescopic plate.

[0007] Preferably, the surface of the first conveyor table is provided with a first track conveying structure, and the surface of the second conveyor table is provided with a second track conveying structure.

[0008] Preferably, the length of the electromagnet is less than the length of the first tracked conveyor structure.

[0009] Preferably, an electric push plate is installed on both sides of the first track conveyor structure and the second track conveyor structure, and a protective shell is installed on the other end of the electric push plate. Multiple driven shafts are installed in an array inside the protective shell.

[0010] Preferably, the lower end of the protective shell is provided with an array of movable wheels at the connection point with the first tracked conveyor structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This laser coding anti-counterfeiting printing equipment places the metal parts to be coded onto the surface of the first conveyor table. Laser heads on the inner sides of the two first side plates perform laser anti-counterfeiting coding on one side of the metal parts. After coding, the metal parts continue to be conveyed to the second conveyor table. For parts requiring coding on the reverse side, when passing under the electromagnet, two lifting plates lower the electromagnet, bringing it into contact with the part's surface and energizing it. The electromagnet then attracts the part. The two lifting plates then raise the electromagnet, while a drive motor rotates the shaft and electromagnet 180 degrees, flipping the part above the electromagnet. The lifting plates then lower the electromagnet and part, bringing one end of the part into contact with the surface of the second conveyor table. The electromagnet is then de-energized, and the part continues to be conveyed by the second conveyor table, moving between the two second side plates for secondary coding by the laser heads on the second side plates. The entire process is automatic, requiring no manual intervention, significantly saving time and costs.

[0013] 2. This laser marking anti-counterfeiting printing equipment uses two electric push plates installed inside the first and second conveyor tables. The electric push plates drive the protective shell and multiple driven shafts to move, moving the driven shafts to both sides of the metal parts. This limits the position of the metal parts, making the marking more accurate. Attached Figure Description

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 3 As shown, the laser coding anti-counterfeiting printing equipment in this embodiment includes a first conveyor table 1, and a second conveyor table 2 is installed on the upper end of the first conveyor table 1. The length of the first conveyor table 1 is greater than the length of the second conveyor table 2. Figure 1As shown, a second conveyor 2 is installed on the upper end of the first conveyor 1. Metal parts requiring marking first enter the surface of the first conveyor 1. Metal parts requiring secondary marking can be fed from the surface of the first conveyor 1 to the surface of the second conveyor 2 for secondary marking. Metal parts not requiring secondary marking are directly conveyed from the surface of the first conveyor 1 to the outside. A first side plate 3 is installed on both sides of the first conveyor 1, and a second side plate 5 is installed on both sides of the second conveyor 2. A telescopic plate 7 is installed on the inner side of both the first side plate 3 and the second side plate 5. The telescopic plate 7 can... It can telescopically move in the horizontal direction and is driven by electricity. A laser head 11 is installed at the lower end of the telescopic plate 7 for anti-counterfeiting coding. A lifting plate 4 is installed between the first side plate 3 and the second side plate 5 and outside the first conveyor table 1. The lifting plate 4 is electrically lifted and connected to an external power source. A rotating shaft 8 is connected between the two lifting plates 4. One end of the rotating shaft 8 is connected to a drive device. An electromagnet 9 is installed at the center of the surface of the rotating shaft 8. The drive device is a common servo motor that can drive the rotating shaft 8 and the electromagnet 9 to rotate.

[0022] Specifically, a groove 16 is provided on the inner side of both the first side plate 3 and the second side plate 5. A threaded rod 10 is rotatably connected inside the groove 16. One end of the threaded rod 10 is connected to a driving device. A movable plate 6 is threadedly connected to the surface of the threaded rod 10. The front end of the movable plate 6 is connected to one end of the telescopic plate 7. The threaded rod 10 is driven to rotate by the driving device. When the threaded rod 10 rotates, the movable plate 6 is threadedly connected to the surface of the threaded rod 10. The movable plate 6 will rotate along the length direction of the threaded rod 10, thereby driving the telescopic plate 7 to move.

[0023] Furthermore, the surface of the first conveyor table 1 is provided with a first track conveyor structure 12, and the surface of the second conveyor table 2 is provided with a second track conveyor structure 13. The length of the electromagnet 9 is less than the length of the first track conveyor structure 12, and the arm shaft 8 of the electromagnet 9 is wider. The lifting plate 4 can drive the shaft 8 and the electromagnet 9 to move up and down. When the shaft 8 is above the first conveyor table 1, the electromagnet 9 can penetrate into the interior of the first track conveyor structure 12 and then contact the metal parts that need to be marked.

[0024] Furthermore, an electric push plate 14 is installed on both sides of the first track conveyor structure 12 and the second track conveyor structure 13. A protective shell 15 is installed on the other end of the electric push plate 14. Multiple driven shafts 17 are arranged in an array inside the protective shell 15. Moving wheels 18 are arranged in an array at the lower end of the protective shell 15 where it connects to the first track conveyor structure 12. By installing two electric push plates 14 inside the first conveyor table 1 and the second conveyor table 2, the electric push plates 14 drive the protective shell 15 and the multiple driven shafts 17 to move, moving the driven shafts 17 to both sides of the metal parts. This can limit the position of the metal parts, making the marking of the metal parts more accurate.

[0025] The usage method of this embodiment is as follows: The metal parts that need to be coded are placed on the surface of the first conveyor table 1. The laser heads 11 on the inner side of the two first side plates 3 perform laser anti-counterfeiting coding on one side of the metal parts. After anti-counterfeiting coding, the metal parts continue to be conveyed to the second conveyor table 2. When the parts that need to be coded on the reverse side pass under the electromagnet 9, the two lifting plates 4 will drive the electromagnet 9 to descend, so that the electromagnet 9 contacts the surface of the part and is energized. At this time, the electromagnet 9 will attract the part. Then, the two lifting plates 4 will drive the electromagnet 9 to rise. At the same time, the drive motor will drive the rotating shaft 8 and the electromagnet 9 to rotate 180 degrees. At this time, the part will be flipped to the top of the electromagnet 9. At the same time, the lifting plates 4 will drive the electromagnet 9 and the part to descend, so that one end of the part contacts the surface of the second conveyor table 2. At this time, the power to the electromagnet 9 is turned off. The part will then be conveyed by the second conveyor table 2 and moved between the two second side plates 5. The laser heads 11 on the second side plates 5 will perform secondary coding. The whole process is automatic and does not require manual intervention, which can save time and costs to a large extent.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
