Detailed Description of the Embodiment

[0022] The following further describes the present application in detail Figures 2-4 in conjunction with the accompanying drawings.

[0023] An embodiment of the present application discloses an adjustable laser marking device.

[0024] Referring to Figure 2 and Figure 3 , the adjustable laser marking device includes a base 5, a workpiece is placed on the base 5, a positioning mechanism for fixing the workpiece is arranged on the base 5, a first sliding frame 6 is slidably connected to the base 5, a marking machine 8 is arranged on the first sliding frame 6 through a lifting mechanism, and a first driving unit for driving the first sliding frame 6 to horizontally slide is arranged on the base 5.

[0025] Therefore, when a laser marking operation needs to be performed on the marking area 4 of the workpiece, the operator places the workpiece on the base 5, uses the positioning mechanism to fix the workpiece, reduces the possibility of the workpiece shaking during the laser operation, starts the first driving unit, drives the first sliding frame 6 to slide on the base 5, so as to realize the adjustable position of the marking machine 8 in the horizontal direction, improve the flexibility and the adaptation range of the overall laser marking device, facilitate the marking operation on different areas of different models of workpieces, and improve the efficiency of laser marking.

[0026] Referring to Figure 2 and Figure 3 On the first sliding frame 6, a second sliding frame 7 is slidably connected, and the moving directions of the first sliding frame 6 and the second sliding frame 7 are perpendicular to each other. The first driving unit includes a mounting frame 24 provided on the base 5. Two relatively arranged first linear modules 25 are mounted on the mounting frame 24. Both ends of the first sliding frame 6 are respectively mounted on the sliders of the two first linear modules 25. A second driving unit for driving the second sliding frame 7 to slide is provided on the first sliding frame 6. The second driving unit includes a second linear module 26 provided on the first sliding frame 6. The second sliding frame 7 is bolted to the slider of the second linear module 26.

[0027] Therefore, by starting the first linear module 25, the first sliding frame 6 is driven to slide, so as to realize the adjustable position of the marking machine 8 in the Y-axis direction horizontally. By starting the second linear module 26, the second sliding frame 7 is driven to slide, so as to realize the adjustable position of the marking machine 8 in the X-axis direction horizontally. The Y-axis direction and the X-axis direction are two mutually perpendicular directions horizontally. While having stronger flexibility, the adaptation range of the overall laser marking device is improved, which is convenient for dealing with the marking operations on different regions of workpieces of different models, and the efficiency of laser marking is improved.

[0028] Referring to Figure 2 and Figure 3 The lifting mechanism includes a vertically arranged support frame 9 slidably connected to the second sliding frame 7. The marking machine 8 is arranged on the support frame 9. A lifting unit for driving the support frame 9 to lift is provided on the second sliding frame 7. The lifting unit in the embodiment of the present application includes a third linear module 27 vertically arranged on the second sliding frame 7. The support frame 9 is bolted to the slider of the third linear module 27. Therefore, by starting the third linear module 27, the support frame 9 is driven to move along with the slider of the third linear module 27, so as to drive the marking machine 8 to realize the lifting in the Z-axis direction vertically, and the height between the marking machine 8 and the marking area 4 of the workpiece is adjustable.

[0029] Referring to Figure 3 and Figure 4, the positioning mechanism includes a bottom plate 10 provided on the base 5. A handle 29 is bolted to the bottom plate 10. In the embodiment of the present application, a plurality of weight-reducing holes 30 are formed in the bottom plate 10. The weight-reducing holes 30 reduce the weight of the bottom plate 10, and it is convenient for the operator to carry the positioning mechanism by using the handle 29. A first support column 11 and a second support column 12 are bolted to the bottom plate 10. At one end of the first support column 11 away from the base 5, a first positioning frame 13 matching the size of the first connection end 2 is installed. At one end of the second support column 12 away from the base 5, a second positioning frame 14 matching the second connection end 3 is installed. The first connection end 2 of the workpiece is placed in the first positioning frame 13 and the second connection end 3 is placed in the second positioning frame 14.

[0030] Therefore, the first positioning frame 13 plays a limiting role on the first connection end 2 of the workpiece, and the second positioning frame 14 plays a limiting role on the second connection end 3 of the workpiece. While the first positioning frame 13 and the second positioning frame 14 support the workpiece, they reduce the possibility of the workpiece shifting in position during the laser marking process, improving the stability of the workpiece placement.

[0031] Refer to Figure 3 and Figure 4 , a third support column 15 is provided on the bottom plate 10. The third support column 15 is located between the first support column 11 and the second support column 12. At one end of the third support column 15 away from the bottom plate 10, a stabilizing frame 16 matching the size of the frame 1 of the workpiece is installed. The frame 1 of the workpiece is placed on the stabilizing frame 16. The stabilizing frame 16 supports the frame 1 of the workpiece, balancing the center of gravity of the workpiece and further improving the stability of the workpiece placement. In the embodiment of the present application, the number of the first support column 11, the second support column 12, and the third support column 15 can be set to multiple according to the actual situation, so as to facilitate the laser marking operation of multiple workpieces at the same time and improve the production efficiency.

[0032] Refer to Figure 3 and Figure 4, a rodless cylinder 17 is installed on the base 5. The rodless cylinder 17 can be a magnetic coupling rodless cylinder. A sliding table 18 is arranged at the output end of the rodless cylinder 17. A connecting plate 19 is bolted to the sliding table 18. The bottom plate 10 is arranged on the connecting plate 19. Installation bolts are sequentially arranged through the bottom plate 10 and the connecting plate 19 on the bottom plate 10. An installation nut is threadedly connected to the outer edge of the installation bolt. The connecting plate 19 is pressed tightly between the installation bolt and the installation nut. In the embodiment of the present application, a placement frame 28 is placed on one side of the base 5. Multiple workpieces of different models and positioning mechanisms adapted to the workpieces of different models can be placed in the placement frame 28. According to the actual situation on site, when marking operations need to be performed on workpieces of different models, the operator can remove the bottom plate 10 from the connecting plate 19 by means of bolt disassembly, and then remove the positioning mechanism and replace it with a positioning mechanism adapted to the workpieces of different models. The positioning principles of the positioning mechanisms of different models are the same. The positions of the first support column 11, the second support column 12, and the third support column 15 and the sizes of the first positioning frame 13, the second positioning frame 14, and the stable frame 16 are only adjusted adaptively according to the workpiece model. The replaced workpiece is erected on the replaced positioning mechanism, meeting the diversified production requirements and improving the versatility and production efficiency of the adjustable laser marking device.

[0033] Therefore, start the rodless cylinder 17 to drive the sliding table 18 at the output end of the rodless cylinder 17 to move. During the movement of the sliding table 18, the connecting plate 19 and the bottom plate 10 are driven to move synchronously, so as to realize the adjustable position of the workpiece on the bottom plate 10, further improving the flexibility and application range.

[0034] Refer to Figure 3 and Figure 4 , two guide rails 20 parallel to the rodless cylinder 17 are bolted to the base 5. The rodless cylinder 17 is located between the two guide rails 20. Sliders 21 matching the sizes of the guide rails 20 are respectively slidably connected to the two guide rails 20. The connecting plate 19 is arranged on the two sliders 21. The guide rails 20 play a role in limiting the moving position of the sliders 21, reducing the possibility of position deviation during the movement of the connecting plate 19 and improving the stability of the connecting plate 19 during movement.

[0035] Refer to Figure 3 and Figure 4 , a collision block 22 is bolted to the surface of the connecting plate 19 facing the base 5. A hydraulic buffer 23 is installed on the base 5. The collision block 22 corresponds to the output end of the hydraulic buffer 23. The hydraulic buffer 23 can convert the impact force or vibration into the flow of oil, enabling the collision block 22 to stop smoothly when being impacted, thereby improving the stability and reliability of the connecting plate 19.

[0036] The implementation principle of the embodiment of this application is as follows: When laser marking operation needs to be performed on the marking area 4 of the workpiece, the operator places the first connection end 2 of the workpiece in the first positioning frame 13 and the second connection end 3 of the workpiece in the second positioning frame 14, thereby fixing the workpiece and reducing the possibility of the workpiece shaking during the laser operation. Start the first linear module 25 to drive the first sliding frame 6 to slide, so as to realize the adjustable position of the marking machine 8 in the Y-axis direction horizontally; start the second driving unit to drive the second sliding frame 7 to slide, so as to realize the adjustable position of the marking machine 8 in the X-axis direction horizontally; start the lifting unit to drive the support frame 9 to slide, thereby driving the marking machine 8 to move up and down in the Z-axis direction vertically, so that the height of the marking machine 8 from the marking area 4 of the workpiece is adjustable. Move the marking end of the marking machine 8 to directly above the marking area 4, and the marking machine 8 performs marking operation on the marking area 4 of the workpiece. While having stronger flexibility, it improves the adaptation range of the overall laser marking device, facilitates dealing with the marking operations on different areas of workpieces of different models, and improves the efficiency of laser marking.
