Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and more specifically, to a fixture for a laser marking machine. Background Technology

[0002] Laser marking machines use laser beams to evaporate, chemically and physically alter, or ablate the surface of materials, creating permanent graphics or text. Their core characteristics are high efficiency, precision, and durable marking. The basic components include a laser, a galvanometer system, optical elements (field lens, beam combiner), and control software. For example, fiber laser marking machines require a galvanometer to control the beam trajectory, and a red light indicator to assist in positioning. During the marking process, a fixture is needed to fix the workpiece, ensuring its stability and thus guaranteeing the stability and quality of the marking, improving the yield rate. Sheet-shaped workpieces are common targets for laser marking.

[0003] Most existing laser marking machine fixtures are equipped with a planar placement and positioning mechanism. During use, the sheet-like workpiece is placed on the plate. After marking, it is often necessary to slide and move the workpiece or clamp the warped edge to remove the sheet-like workpiece. Sliding and warping can easily cause certain surface or structural damage to the sheet-like workpiece, affecting subsequent processing and use, and affecting product quality.

[0004] In summary, to address the issue of difficulty in removing sheet-like workpieces from the laser marking machine fixture during laser marking, or the potential impact on the quality of the workpieces, the laser marking machine fixture needs to be able to position the sheet-like workpieces and facilitate their removal after laser marking, thereby reducing damage to the workpieces. Utility Model Content

[0005] The present invention provides a laser marking machine fixture, which aims to solve the following problem: existing laser marking machine fixtures often require sliding to move the workpiece or clamping the warped edge to remove sheet-like workpieces.

A support block 16 is fixedly connected to the lower end of the second movable frame 13. The support block 16 is slidably connected to the support rod 12. A threaded rod 17 is rotatably connected to the inner side of the first docking block 9. The threaded rod 17 is threadedly connected to the second docking block 15.

[0023] It should be noted that the first movable frame 7 and the second movable frame 13 are placed on the mounting platform 1, and the sheet-like workpiece is placed on the first support plate 8 and the second support plate 14, which facilitates positioning and subsequent marking. The second movable frame 13 is supported by the support rod 12 and the support block 16, and the threaded rod 17 is rotated, which in turn drives the second docking block 15 and the second movable frame 13 to move in conjunction with the first docking block 9, so that the first movable frame 7 and the second movable frame 13 move closer or further away to adapt to the workpiece specifications.

[0024] It is worth noting that the first movable frame 7 and the second movable frame 13 can slide back and forth on the mounting table 1 through the positioning block 10, thereby enabling the first movable frame 7 to detach from the mounting table 1, which facilitates the removal of sheet-like workpieces from the sides and rear. This reduces the possibility of bending of the sheet-like workpieces during placement, positioning and removal, and ensures processing quality.

[0025] Refer to the instruction manual appendix Figure 2 The mounting platform 1 has sliding grooves 2 on both sides, and positioning bolts 3 are provided on the outer side of the sliding grooves 2. The upper end of the mounting platform 1 has a mating groove 4, and the positioning rod 11 is slidably connected to the mounting platform 1.

[0026] It should be noted that the first movable frame 7 and the second movable frame 13 are placed on the mounting platform 1 to facilitate the placement and positioning of the workpiece.

[0027] Refer to the instruction manual appendix Figure 2The lower inner side of the mounting platform 1 is provided with a first positioning groove 5, and the two sides of the first positioning groove 5 are provided with second positioning grooves 6. The support block 16 is slidably connected to the first positioning groove 5, and the first docking block 9 and the second docking block 15 are slidably connected to the second positioning groove 6.

[0028] It should be noted that the first positioning groove 5 and the second positioning groove 6 facilitate the normal movement of the first moving frame 7 and the second moving frame 13.

[0029] Refer to the instruction manual appendix Figure 3 The upper ends of the first movable frame 7 and the second movable frame 13 are rotatably connected to a rotating frame 18. A support spring 19 is provided on the inner side of the rotating frame 18, and a pressure block 20 is slidably connected to both sides of the rotating frame 18.

[0030] It should be noted that the working method is similar to that of a spring clamp, which allows the support spring 19 to work in conjunction with the first moving frame 7 and the second moving frame 13 to drive the rotating frame 18 and the pressing block 20 to rotate, thereby pressing down on the positioning sheet-like workpiece.

[0031] Refer to the instruction manual appendix Figure 4 The lower end of the mounting platform 1 is provided with a placement platform 21. Both sides of the placement platform 21 are fixedly connected with support frames 22. The support frames 22 are slidably connected to the mounting platform 1 through a sliding groove 2. The lower end of the placement platform 21 is fixedly connected with a connecting block 23.

[0032] It should be noted that the mounting platform 1 is moved and positioned by the support frame 22 in conjunction with the slide 2 and the positioning bolts 3, so that the position can be adjusted normally for laser marking.

[0033] Refer to the instruction manual appendix Figure 4 A base body 24 is provided on the outer side of the connecting block 23, and a connecting rod 25 is fixedly connected to the inner side of the base body 24. The connecting rod 25 is slidably connected to the connecting block 23.

[0034] It should be noted that the base body 24 and the connecting rod 25 work together with the connecting block 23 to move the placement platform 21, thereby assisting in positioning.

[0035] Refer to the instruction manual appendix Figure 5 The upper end of the docking groove 4 is provided with a placement rack 26, the inner side of the placement rack 26 is slidably connected with a first baffle plate 27, and the lower end of the first baffle plate 27 is provided with a second baffle plate 28.

[0036] It should be noted that by connecting the mounting bracket 26 to the docking slot 4, and by defining the marking area with the first blocking plate 27 and the second blocking plate 28, the impact of laser marking on other positions is reduced.

[0037] It is worth noting that the positioning rod 11 is connected to the mounting platform 1, which facilitates the normal movement of the first movable frame 7 and the second movable frame 13. At the same time, the connecting block 23 is provided with a limit bolt, which can cooperate with the connecting rod 25 to fix the positioning platform 21. The support frame 22 is provided with a positioning groove, which can cooperate with the positioning bolt 3 to fix the mounting platform 1, which facilitates the positioning of sheet-like workpieces.

[0038] Working principle: First, the threaded rod 17 is rotated, which in turn drives the second docking block 15 and the second moving frame 13 to move in conjunction with the first docking block 9, so that the first moving frame 7 and the second moving frame 13 move closer or further apart. Then, the sheet-like workpiece is placed through the first support plate 8 and the second support plate 14, which facilitates positioning and subsequent marking. Then, the support spring 19, in conjunction with the first moving frame 7 and the second moving frame 13, drives the rotating frame 18 and the pressing block 20 to rotate, thereby pressing down and positioning the sheet-like workpiece. After marking is completed, the positioning block 10 slides back and forth on the mounting table 1, which allows the first moving frame 7 to detach from the mounting table 1, thus facilitating the removal of the sheet-like workpiece from the sides and rear.

[0039] In use, firstly, the first movable frame 7 and the second movable frame 13 are placed on the mounting platform 1, and the first positioning groove 5 and the second positioning groove 6 facilitate the normal movement of the first movable frame 7 and the second movable frame 13. Next, the mounting platform 1 is moved and positioned by the support frame 22 in conjunction with the sliding groove 2 and the positioning bolt 3, so as to facilitate normal adjustment of the position for laser marking. Then, the placement platform 21 is moved by the base body 24 and the connecting rod 25 in conjunction with the connecting block 23. Finally, the placement frame 26 is connected to the docking groove 4, and the marking area is defined by the first blocking plate 27 and the second blocking plate 28 to reduce the impact of laser marking on other positions.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
