Description

Technical Field

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

[0002] Laser marking machines use high-energy laser beams to create permanent marks on or inside objects through thermal or photochemical effects. Small, portable laser marking machines offer significant advantages: they are lightweight and portable, allowing for flexible operation in various scenarios such as outdoor construction and temporary exhibitions, and are convenient for on-site customer service. They are easy to operate with a simple interface, requiring only minimal training for beginners; startup is quick and setup is convenient. Furthermore, they are cost-effective, with low purchase, operating, and maintenance expenses. They are highly versatile, capable of marking text, patterns, QR codes, and other rich content on various materials such as metals and plastics.

[0003] In most cases, existing laser marking machines are used by placing the workpiece directly on the machine's table before starting the marking operation. However, existing laser marking machines lack a structure to fix the workpiece in place. If the workpiece is moved due to external force during the marking process, it may cause marking errors, thus affecting the quality of the marking operation. Therefore, a small portable laser marking machine is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a small portable laser marking machine, which aims to improve the problem that laser marking machines often place the workpiece on a table for marking, but lack a fixed structure. External force collisions can easily cause the workpiece to shift, resulting in marking errors and affecting the quality of the work.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a small portable laser marking machine, comprising a main unit, a storage component installed on one side of the outer wall of the main unit, a support plate fixedly connected to one side of the outer wall of the main unit, a support rod fixedly connected to one side of the upper surface of the support plate, a limit plate fixedly connected to one side of the outer wall of the support rod, a marking component installed inside the support rod, and a quick-release component installed inside the support plate;

[0011] The above technical solution achieves precise control of the height of the digital galvanometer.

[0012] Furthermore, the storage component includes a collection box, one side of which is fixedly connected to one side of the outer wall of the main unit chassis, and mounting cotton is fixedly connected inside the collection box.

[0013] The above technical solution achieves the effect of facilitating the storage and holding of components.

[0014] Furthermore, a support roller is fixedly connected to one side of the outer wall of the support rod, and a take-up roller is rotatably connected to the outer wall of the support roller. The main unit and the frame are connected by a connecting line, which is wound around the outer wall of the take-up roller. A cable anti-detachment component is installed on the outer wall of the support roller.

[0015] The above technical solution achieves the effect of facilitating the storage of connecting cables.

[0016] Furthermore, the cable anti-detachment component includes an L-shaped frame, the outer and inner walls of which are fixedly connected to one side of the outer wall of the support roller. A telescopic rod two is fixedly connected to the lower surface of the L-shaped frame. A spring three is sleeved on the outer wall of the telescopic rod two. A connecting frame is fixedly connected to the lower surface of the telescopic rod two. A limiting cylinder is rotatably connected inside the connecting frame. The outer wall of the limiting cylinder abuts against the outer wall of the connecting line.

[0017] The above technical solution effectively prevents the connecting wires from coming loose.

[0018] Furthermore, the outer wall of the T-shaped rod is slidably connected to the inner wall of the clamping block, and the T-shaped rod is used to connect the clamping block.

[0019] The above technical solution achieves the effect of facilitating the rotation of the clamping block.

[0020] Furthermore, one end of the spring is fixedly connected to the lower surface of the L-shaped frame, and the other end of the spring is fixedly connected to the upper surface of the connecting frame.

[0021] The above technical solution achieves the effect of facilitating the movement of the connecting frame.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the workpiece is placed on top of the support plate, and then the insert is inserted into the support plate. The extension and retraction of the first spring drives the rotating plate to lock the clamping block into the support plate. The rotation of the second spring then drives the T-shaped rod to push the clamping block against the workpiece. With the cooperation of the marking component, the workpiece is marked, thereby improving the practicality of the machine.

[0024] 2. In this utility model, by winding the connecting wire around the outer wall of the take-up roller, and then by the extension and retraction of the spring three, the extension and retraction of the telescopic rod two is achieved. At this time, the spring three causes the limiting cylinder inside the connecting frame to abut against the outer wall of the connecting wire. Then, by rotating the take-up roller, the connecting wire is collected and prevented from falling off, thereby improving the practicality of the machine. Attached Figure Description

[0038] Working principle: When using this machine to mark workpieces, firstly, the workpiece is placed above the support plate 12. Then, the insert 13 is inserted into the hole inside the support plate 12. The extension and retraction of spring 15 then causes the rotating plate 16 to rotate. The rotation of the rotating plate 16 causes the clamping block 17 to abut against the inside of the support plate 12. The reaction force of spring 20 then causes the T-shaped rod 21 to slide inside the clamping block 19. The movement of the clamping block 19 then achieves the effect of limiting the workpiece. Finally, by rotating the hand... Wheel 7 causes lead screw 6 to slide threaded sleeve 8 inside limit plate 5. At this time, the threaded sleeve 8 causes digital galvanometer 11 on one side of moving seat 9 to approach the workpiece. Then, the connecting wire 24 connects the main unit 1 and digital galvanometer 11. The digital galvanometer 11 then performs marking operation on the workpiece. At the same time, the connecting wire 24 can be wound around the outer wall of take-up roller 23. Then, the reaction force of spring 3 27 causes the limit cylinder 29 inside the connecting frame 28 on the lower surface of telescopic rod 26 to abut against the outer wall of connecting wire 24, thereby preventing connecting wire 24 from falling off.
