[0037] In this embodiment, the front, middle and rear of the main frame 32 are respectively equipped with a front photoelectric switch 1, a middle photoelectric switch 8 and a rear photoelectric switch 9. The front photoelectric switch 1 and the rear photoelectric switch 9 are used to detect whether the material is being fed, and the middle photoelectric switch 8 is used to detect whether the material is in place.

[0038] In this embodiment, the left fixing plate 17 and the right fixing plate 27 are equipped with protective covers 12.

[0039] In this embodiment, the main frame 32 is fitted with a base 18 at its bottom, and the base 18 is T-shaped.

[0040] As attached Figure 1 As shown, the overall weight of this embodiment is 82kg. Four T-shaped bases 18 are installed at the bottom of the main frame 32, allowing the entire unit to be installed on a laser marking machine platform. The main frame 32 uses 40*20 profile material. The transmission belt 5 is connected to the conveyor servo motor 10 via a 2M synchronous pulley 11 for transmission.

Four lifting cylinders 7 and two blocking cylinders 6 are installed below the main frame 32. The lifting cylinders 7 are used to lift the workpiece to facilitate laser marking operations. The blocking cylinders 6 are used to block the simulated workpiece 14 from moving forward, which plays a role in accurate positioning. The positions of the lifting cylinders 7 and the blocking cylinders 6 can be freely adjusted.

[0041] As attached Figure 3 and 4As shown, a high-precision active ball screw 28 and a drive servo motor 23 serve as the main transmission components. An active synchronous pulley 24 is connected to the drive servo motor 23. Power is provided by the drive servo motor 23, which drives the driven synchronous pulley 26 to rotate via a drive synchronous belt 25. The driven synchronous pulley 26 is connected to the active ball screw 28, causing it to rotate. The other end of the active ball screw 28 is connected to a 5M driven synchronous pulley 19. A 5M synchronous belt 21 connects the active ball screw 28 and the driven ball screw 31, enabling synchronous rotation of both active ball screws 28 and driven ball screws 31. Idler pulleys 20 are used to tension both sides of the 5M synchronous belt 21. Guide shafts 29 are installed above the driving ball screw 28 and driven ball screw 31 to ensure smooth movement of the simulated workpiece 14 on the main frame 32. The driving ball screw 28 can precisely control the displacement of the left conveyor bracket 16, thereby automatically adjusting the distance between the left conveyor bracket 16 and the right conveyor bracket 15 to accommodate workpieces of different sizes and shapes. Both the driving ball screw 28 and the guide shaft 29 are equipped with dustproof protective sleeves 13 to prevent cutting slag from splashing onto the driving ball screw 28, driven ball screw 31, and guide shaft 29, ensuring transmission accuracy and increasing service life.

[0042] The specific working process of this embodiment is as follows:

[0043] (1) When the simulated workpiece 14 is transferred from the previous process to this embodiment, the photoelectric switch 9 will give a signal to the conveying servo motor 10 to start after detecting that there is material.

[0044] (2) The conveying servo motor 10 drives the transmission belt 5 through the 2M synchronous pulley 11 to slowly advance the simulated workpiece 14, while the blocking cylinder 6 is raised.

[0045] (3) When the simulated workpiece 14 reaches the position of the intermediate photoelectric switch 8, the blocking cylinder 6 will restrict the simulated workpiece 14 from moving forward. At the same time, after the intermediate photoelectric switch 8 detects that there is material, it will give a signal to the conveying servo motor 10 to stop rotating, and at the same time, it will give a signal to the lifting cylinder 7.

[0046] (4) After receiving the signal, the lifting cylinder 7 will perform an upward action to lift the simulated workpiece 14 and clamp the simulated workpiece 14 with the upper stainless steel baffle to perform laser marking.

[0047] (5) After the marking work is completed, the lifting cylinder 7 returns to the initial position, places the simulated workpiece 14 on the transmission belt 5, and sends a signal to the conveying servo motor 10 to continue rotating. At the same time, it sends a signal to the blocking cylinder 6. After receiving the signal, the blocking cylinder 6 returns to the initial position.

[0048] (6) The simulated workpiece 14 continues to move forward through the belt conveyor mechanism. After it moves to the position of the front photoelectric switch 1 at the rear end, the front photoelectric switch 1 detects that the simulated workpiece 14 has been processed and sends a signal to the previous process to continue processing the next simulated workpiece 14.

[0049] (7) At this point, the overall laser marking process is complete.

[0050] Changing workpieces of different sizes: By controlling the forward and reverse rotation of the transmission servo motor 23, the transmission synchronous belt 25 drives the driven synchronous pulley 26 to rotate, which in turn drives the active ball screw 28 to rotate, controlling the movement of the left conveyor bracket 16, thereby automatically adjusting the distance between the left conveyor bracket 16 and the right conveyor bracket 15 to accommodate workpieces of different sizes.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
