Description

Technical Field

[0001] The utility model relates to the field of laser printing, in particular to a running device for marking laser printing. Background Art

[0002] Laser printing identification usually refers to laser marking technology, which is a marking method that uses high-energy-density lasers to partially irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent mark. The basic principle of laser marking is that a laser generator generates a high-energy continuous laser beam, and the focused laser acts on the substrate, causing the surface material to melt instantly or even vaporize. By controlling the path of the laser on the surface of the material, the required graphic mark is formed. In this process, the laser beam is like a fine "tool" that removes the surface material of the object point by point, achieving non-contact processing, without generating mechanical extrusion or mechanical stress, and therefore will not damage the processed object.

[0003] After searching, the document with publication number CN221210302U discloses an operating structure for laser printing of aluminum ingot markings, including a base, the top surface of the base is fixedly connected with a fixing component and a trough body, the inside of the trough body is rotatably connected with a threaded rod three, one end of the threaded rod three is fixedly connected to the output end of the motor two, the outer side of the threaded rod three is threadedly connected with a threaded block, the top surface of the threaded block is fixedly connected with a connecting plate, and the top surface of the connecting plate is fixedly connected with a precise positioning mechanism. In the utility model, by driving the motor two, the threaded rod three drives the threaded block to move, and then drives the precise positioning mechanism to move left and right, by driving the electric push rod, the frame one moves up and down, and by driving the motor one, the slider drives the laser print head to move forward and backward, thereby achieving the effect of accurately positioning and adjusting the position of the laser print head.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] like Figure 1-5 As shown, the utility model provides an operating device for marking laser printing, including a workbench 100, and a support frame 200 fixedly arranged on the top of the workbench 100, a clamping frame 300 is installed on the top of the workbench 100, and a fixing component 400 for fixing a workpiece is arranged in the clamping frame 300, electric push rods Ⅰ500 are installed on both sides above the support frame 200, and an optical axis driving mechanism 600 located below the support frame 200 is installed at the movable end of the electric push rod Ⅰ500, and a laser printing head 700 is arranged below the optical axis driving mechanism 600;

[0028] Among them, the fixing component 400 includes a gear 401, two racks 404 meshing with the gear 401, connecting rods 403 respectively fixedly connected to the two racks 404, and splints 402 respectively fixedly connected to the two connecting rods 403.

[0035] In this embodiment, the X-axis moving block 6024 is fixedly connected below the Y-axis moving block 6014 , and the laser printing head 700 is fixedly installed at the bottom of the X-axis moving block 6024 .

[0036] How to use and working principle of this device:

[0037] When the device is used, the product is first placed on the partition 301, and one of the clamping plates 402 is pushed by the electric push rod Ⅰ500. The clamping plate 402 moves the rack 404 through the connecting rod 403. The rack 404 moves to drive the gear 401 to rotate and the other rack 404 drives the clamping plate 402 connected thereto to move. The two clamping plates 402 move toward each other to clamp and fix the product, simplifying the operation and converting it into an electric mode, reducing the time of early clamping and improving the processing efficiency.

[0038] When laser printing is performed, the Y-axis active sprocket 6016 is driven to rotate by the Y-axis motor 6015, and the Y-axis slider 6012 is moved along the Y-axis rail 6011 through the transmission of the Y-axis chain 6018, thereby driving the Y-axis moving block 6014 to move to adjust the laser printing head 700 in the Y-axis direction. After the adjustment is completed, the X-axis active sprocket 6026 is driven to rotate by the X-axis motor 6025, and the X-axis slider 6022 is moved along the Y-axis rail 6011 through the transmission of the X-axis chain 6028, thereby driving the X-axis moving block 6024 to move to adjust the laser printing head 700 in the X-axis direction. Finally, the optical axis driving mechanism 600 is pushed by the electric push rod Ⅰ500 to adjust the laser printing head 700 downward in the Z-axis direction. The distance between the laser printing head 700 and the product is minimized and can even be fitted. Therefore, there is no problem that the distance between the laser printing head 700 and the product is too large, which causes the diffusion and attenuation of the laser beam and affects the printing accuracy and quality.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
