Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, and in particular to a portable laser marking device. Background Technology

[0002] Laser marking is a technique that uses a high-energy-density laser beam to permanently mark the surface of different materials. The marking methods include changing the physical and chemical properties of the material surface or directly etching the material. Laser marking is widely used in industrial manufacturing, electronic products, medical devices and consumer products.

[0003] Laser marking involves controlling a laser beam to move at high speed on a target surface, concentrating the laser's thermal energy on the material surface to cause the following reactions: the local high temperature of the laser beam causes the material to evaporate or ablate, forming a recessed mark; changing the surface gloss or color of the material; creating a contrast effect; and forming a permanent mark.

[0004] Although existing laser marking devices can complete the marking operation, in actual use, after a product is marked, the equipment needs to wait for the staff to remove the marked product and place the unmarked product. During the loading and unloading process, the equipment is in a paused state and cannot continue to operate, thus reducing the overall marking efficiency. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 3 and Figure 6 The present invention provides an embodiment of a portable laser marking device, comprising a marking table 1, a support 2 fixedly connected to the upper part of the marking table 1, a marking component inside the support 2 to facilitate marking operations on products, a loading and unloading component inside the marking table 1 to facilitate loading and unloading operations on products during marking, a moving component at the lower part of the marking table 1 to facilitate movement of the device, and an operation panel 17 installed on the right side of the support 2 to display the device's operating status, parameter settings, and error information in real time, so that operators can understand the working status of the device in a timely manner.

[0030] The loading and unloading assembly includes a motor 8, which is fixedly connected inside the marking table 1. A rotating block 9 is fixedly connected to the output end of the motor 8. A protrusion 10 is fixedly connected to the right side of the rotating block 9. A rotating rod 11 is rotatably connected inside the marking table 1. An intermittent plate 12 is fixedly connected to the outside of the rotating rod 11. Guide grooves are provided around the inside of the intermittent plate 12 to facilitate the movement of the protrusion 10. The intermittent plate 12 is in contact with the rotating block 9. A placement platform 13 is fixedly connected to the top of the rotating rod 11. Limiting rods 14 are fixedly connected to both sides of the lower part of the placement platform 13. Placement slots 16 are provided around the upper part of the placement platform 13 to facilitate the placement of products. An annular groove 15 is provided on the upper part of the marking table 1. Two limiting rods 14 are rotatably connected inside the annular groove 15 to facilitate the movement of the limiting rods 14.

[0031] Specifically, in the laser marking operation, firstly, the operator places the products to be marked sequentially into the placement slots 16 around the upper part of the placement table 13. Then, by adjusting the positions of the laser 6 and galvanometer 7, the laser 6 and galvanometer 7 are accurately aligned with the surface of the workpiece to be marked, providing the necessary preparation for subsequent marking operations. Next, the motor 8 is started, and the motor 8, along with the rotating block 9 connected to its output end, rotates. The rotating block 9 drives the protrusion 10 fixed on the outer right side to rotate as well. When the protrusion 10 rotates to the designated position on the intermittent plate 12, it engages in the guide groove inside the intermittent plate 12. At this time, the rotation of the protrusion 10 drives the intermittent plate 12 to rotate. As the intermittent plate 12 rotates, the rotating rod 11 fixed inside it is also driven to rotate. The rotation of the rotating rod 11 ultimately drives the placement table 13 fixed at the top to rotate synchronously. The rotation of the placement table 13 causes its... Products placed around the top perimeter move sequentially. Products that have been marked are moved away from under the galvanometer 7, while unmarked products are moved under the galvanometer 7 and into the marking area. At this time, the protrusion 10 automatically releases its drive on the intermittent plate 12, ensuring that the placement table 13 is fixed in the marking position and no longer moves. With the positioning of the galvanometer 7 and the high-energy laser beam of the laser 6, the product surface begins to be marked, enabling high-precision marking of text, patterns, QR codes, etc. At the same time, the operator can take advantage of the stable state of the equipment to remove the marked products from the placement slot 16 and replace them with new products to be marked. Throughout the process, the motor 8 and the protrusion 10 rotate continuously, constantly driving the intermittent plate 12 and the placement table 13 to rotate periodically, realizing the synchronous operation of marking and loading / unloading without frequent equipment pauses, thus ensuring continuous operation of the equipment and improving marking efficiency.

[0032] Reference Figure 4 , Figure 5 and Figure 7The moving assembly includes a horizontal plate 18, which is fixedly connected inside the marking table 1. An electric push rod 19 is fixedly connected to the upper part of the horizontal plate 18. A moving block 20 is fixedly connected to the output end of the electric push rod 19. Adjusting plates 21 are rotatably connected to both sides of the moving block 20. Fixed rods 22 are fixedly connected to both sides inside the horizontal plate 18. Sliding sliders 23 are slidably connected to the outside of the two fixed rods 22. The bottom of the two adjusting plates 21 is rotatably connected to the upper part of the two sliding sliders 23. Adjusting plates 24 are rotatably connected to the lower part of the two sliding sliders 23. A moving plate 25 is slidably connected to the bottom of the marking table 1. The bottom of the two adjusting plates 24 is rotatably connected to the upper sides of the moving plate 25. Guide blocks 27 are fixedly connected to both sides. Rollers 26 are installed around the lower part of the moving plate 25. The rollers 26 facilitate the movement of the device. Slide grooves 28 are opened on both sides inside the marking table 1. Two guide blocks 27 are slidably connected inside the two slide grooves 28. The slide grooves 28 facilitate the movement of the guide blocks 27. A telescopic rod 29 is fixedly connected to the lower part of the horizontal plate 18. The top of the telescopic rod 29 is fixedly connected to the upper part of the moving plate 25. The telescopic rod 29 assists in the movement of the moving plate 25. Through holes 30 are opened on both sides inside the horizontal plate 18. Two sliders 23 are slidably connected inside the two through holes 30. The through holes 30 facilitate the movement of the sliders 23.

[0033] Specifically, when the laser marking device needs to be moved, firstly, by activating the electric push rod 19, the output end of the electric push rod 19 begins to move, driving the fixedly connected moving block 20 to move upward. The rise of the moving block 20 simultaneously drives the two externally rotatably connected adjusting plates 21 to move upward synchronously. The movement of the adjusting plates 21 further drives the slider 23 rotatably connected at its bottom to move relative to the outside of the fixed rod 22. When the slider 23 moves relative to the fixed rod 22, it drives the two externally rotatably connected adjusting plates 24 to move downward synchronously. The downward movement of the adjusting plates 24 directly drives the bottom-connected moving plate 25 to move downward. As the moving plate 25 moves downward, the rollers 26 installed around its lower perimeter come into contact with the ground. The contact action of the roller 26 further lifts the entire marking device, causing the marking table 1 at its bottom to detach from the ground. Through the flexible contact between the roller 26 and the ground, the operator can easily push the device and quickly move it to the location where marking is required. Once the device has moved to the designated position, the moving plate 25 can be raised by reversing the operation of the electric push rod 19, causing the roller 26 to detach from the ground, and the marking table 1 to re-contact and fix itself to the ground, thus achieving stable installation of the equipment and preparing it for marking. This facilitates the movement of the marking device, allows for quick position adjustments, adapts to multi-point marking needs, effectively avoids production process interruptions caused by fixed equipment positions, and thus improves overall work efficiency.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The marking assembly includes a lead screw 4, which is rotatably connected inside the bracket 2. A turntable 3 is fixedly connected to the top of the lead screw 4. An adjusting block 5 is threadedly connected to the outside of the lead screw 4. A laser 6 is mounted on the outside of the adjusting block 5. A galvanometer 7 is mounted on the outside of the laser 6.

[0035] Specifically, during marking, firstly, the rotating turntable 3 rotates the lower fixed lead screw 4 inside the bracket 2. As the lead screw 4 rotates, the externally threaded adjusting block 5 moves downward. As the adjusting block 5 moves, the externally mounted laser 6 moves. The movement of the laser 6 moves the externally mounted galvanometer 7, ensuring that the laser beam is aligned with the surface of the target workpiece. Then, by activating the laser 6, the laser beam is projected onto the workpiece surface through the galvanometer 7. The laser beam acts on the workpiece surface with high energy density to make a mark, thus completing the marking operation.

[0036] Working principle: During marking, firstly, the product is placed sequentially inside the placement slots 16 on the upper perimeter of the placement table 13. Then, by adjusting the positions of the laser 6 and the galvanometer 7, the motor 8 is started during marking. The motor 8 drives the rotating block 9 fixed at the output end to rotate, and the rotating block 9 drives the protrusion 10 fixed on the outer right side to rotate. When the protrusion 10 rotates to the position of the intermittent plate 12, the protrusion 10 will engage with the guide groove inside the intermittent plate 12. Then, as the protrusion 10 rotates, it drives the intermittent plate 12 to rotate. The rotation of the intermittent plate 12 drives the rotating rod 11 fixed inside to rotate, and the rotation of the rotating rod 11 drives the rotation of the placement table 13 fixed at the top. The rotation of the placement table 13 drives the upper perimeter of the placement slots 16 to rotate. The product is rotated, and the marked product is moved away from under the galvanometer 7. The unmarked product is moved to the bottom of the galvanometer 7. When the protrusion 10 releases the drive of the intermittent plate 12, the placement table 13 will not move. The product is marked by the galvanometer 7. At the same time, the operator can take the marked product out of the placement slot 16 and replace the unmarked product. The continuous rotation of the protrusion 10 drives the intermittent plate 12 to move continuously, thereby completing the product marking operation and loading and unloading operation. During this process, there is no need to shut down the equipment. Marking and loading and unloading can be completed without stopping the equipment during the marking process, which greatly reduces the idle time of the equipment and improves the marking efficiency.

[0037] When the device needs to be moved, the electric push rod 19 is activated. The electric push rod 19 moves the moving block 20 fixed at the output end upward. The movement of the moving block 20 moves the adjusting plates 21 rotatably connected to the two outer sides in sync. The movement of the two adjusting plates 21 moves the two sliders 23 rotatably connected to the bottom relative to each other outside the two fixed rods 22. When the two sliders 23 move relative to each other, they move the two adjusting plates 24 rotatably connected to the bottom in sync. The two adjusting plates 24 rotatably connect the moving plate 25 rotatably connected to the bottom in sync and move the moving plate 25 downward. The downward movement of the moving plate 25 moves the rollers 26 installed around the bottom in sync. The rollers 26 contact the ground and lift the marking table 1 off the ground, thus completing the movement of the device. This makes it easy to move the marking device, which can be quickly moved to the location where marking is needed without complicated installation or workpiece movement, reducing interruptions in the production process and improving overall work efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
