Description

Technical Field

[0001] This utility model relates to the field of laser marking machine technology, and in particular to a lightweight, non-slip handheld laser marking machine. Background Technology

[0002] Laser marking technology, with its advantages of being non-contact, requiring no consumables, and producing permanent and clear marks, has gradually replaced traditional marking methods such as inkjet printing and stamping, becoming the preferred process for component traceability and brand anti-counterfeiting in industries such as 3C electronics, medical devices, hardware tools, and jewelry. In recent years, with the fragmentation of consumer scenarios and the surge in customized orders, the market demand for marking equipment that is "mobile, easy to use, and low-cost" has rapidly increased; especially for large, difficult-to-handle workpieces (such as engineering robotic arms, automobile frames, and exhibition props), fixed laser workstations can no longer meet the needs of flexible production, thus giving rise to lightweight handheld laser marking machines.

[0003] However, in engineering applications, existing lightweight handheld laser marking machines have a forward-positioned center of gravity, requiring operators to continuously apply downward pressure and maintain a constant speed. Prolonged operation can easily lead to wrist fatigue and quality problems such as inconsistent marking depth and misaligned lines. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a lightweight, non-slip handheld laser marking machine to solve the problems mentioned in the background art.

[0008] Preferably, the walking mechanism includes a pair of rotating frames, and the positioning frame is symmetrically fixedly connected to the left and right sides with first fixing ears. The rotating frames are rotatably connected between the corresponding two first fixing ears. The end of the rotating frame is rotatably connected to a rotating shaft. The side wall of the rotating shaft is fixedly connected to a walking wheel. The rear end of the first fixing ear located on the right side of the positioning frame is fixedly connected to a first servo motor. The output shaft end of the first servo motor is fixedly connected to the rear end of the rotating shaft.

[0009] Preferably, the adjustment mechanism includes a pair of connecting shafts, a second fixing lug is fixedly connected to the upper end of the rotating frame, the connecting shafts are respectively fixedly connected to the rear end of the corresponding second fixing lug, a connecting rod is rotatably connected to the rear end of the second fixing lug, a moving block is rotatably connected to the end of the connecting rod, a bidirectional threaded rod is rotatably connected to the lower end of the laser head through a bearing seat, both ends of the bidirectional threaded rod pass through the moving block and are threadedly connected to it, a second servo motor is fixedly connected to the left end of the laser head, and the output shaft end of the second servo motor is fixedly connected to the left end of the bidirectional threaded rod.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-4 As shown, this utility model has the following two specific embodiments.

[0017] Example 1 A lightweight, non-slip handheld laser marking machine includes a laser head 1, a handle 12 fixedly connected to the right end of the laser head 1, a storage groove 121 formed on the lower side wall of the handle 12, a support mechanism 5 installed inside the storage groove 121 for supporting the handle 12, a mounting bracket 13 fixedly connected to the rear end of the laser head 1, and a positioning frame 14 fixedly connected to the lower end of the mounting bracket 13; it also includes: Walking mechanism 3 is installed on the side wall of positioning frame 14 and is used to drive laser head 1 to move at a constant speed. Adjustment mechanism 4 is installed at the lower end of laser head 1 and is used to adjust walking mechanism 3; Anti-slip sleeve 2 is fitted onto the outer wall of handle 12; The lower end face of the anti-slip sleeve 2 is provided with a clearance hole, which is connected to the storage groove 121. The anti-slip sleeve 2 is made of silicone material. The support mechanism 5 includes a support rod 51, which is hinged inside the storage groove 121 via a damping shaft. A roller 52 is rotatably connected to the left end of the support rod 51, and a handle 53 is fixedly connected to the lower end of the support rod 51.

[0018] In this embodiment, as Figure 1As shown, the operator holds the silicone anti-slip sleeve 2, which increases friction. A slight turn of the handle 53 causes the support rod 51 to rotate out of the storage slot 121 around the damping axis. The roller 52 then adheres to the workpiece surface, forming a fulcrum with the end of the handle 12. The weight of the laser head 1 is distributed, allowing the wrist to remain stable without additional force. After starting the laser head 1, for point marking, the current state is maintained, with the bottom surface of the positioning frame 14 against the workpiece, ensuring stable optical output. For continuous marking, the adjustment mechanism 4 drives the traveling mechanism 3, supporting the positioning frame 14 and moving its lower end away from the workpiece. The traveling mechanism 3 then moves the laser head 1 smoothly, producing even and clear marking lines. After operation, the support rod 51 is retracted, and the roller 52 is stored in the storage slot 121. The entire machine can be stored upright or easily placed in a tool bag for convenient transport.

[0019] Example 2 The difference from Embodiment 1 is that this embodiment discloses the specific structures of the walking mechanism 3 and the adjustment mechanism 4; The walking mechanism 3 includes a pair of rotating frames 32. The positioning frame 14 has first fixed ears 31 symmetrically fixed to the left and right sides. The rotating frames 32 are rotatably connected between the corresponding two first fixed ears 31. The end of the rotating frame 32 is rotatably connected to a rotating shaft 33. The side wall of the rotating shaft 33 is fixedly connected to a walking wheel 34. The rear end of the first fixed ear 31 located on the right side of the positioning frame 14 is fixedly connected to a first servo motor 35. The output shaft end of the first servo motor 35 is fixedly connected to the rear end of the rotating shaft 33.

[0020] The adjustment mechanism 4 includes a pair of connecting shafts 42. The upper end of the rotating frame 32 is fixedly connected to a second fixed ear 41. The connecting shafts 42 are respectively fixedly connected to the rear end of the corresponding second fixed ear 41. The rear end of the second fixed ear 41 is rotatably connected to a connecting rod 43. The end of the connecting rod 43 is rotatably connected to a moving block 44. The lower end of the laser head 1 is rotatably connected to a bidirectional threaded rod 46 through a bearing seat. Both ends of the bidirectional threaded rod 46 pass through the moving block 44 and are threadedly connected to it. The left end of the laser head 1 is fixedly connected to a second servo motor 47. The output shaft end of the second servo motor 47 is fixedly connected to the left end of the bidirectional threaded rod 46.

[0021] The lower end face of the laser head 1 is provided with a dovetail groove 11. Dovetail blocks 45 are slidably connected to the left and right sides inside the dovetail groove 11. The lower ends of the dovetail blocks 45 are fixedly connected to the upper ends of the corresponding moving blocks 44.

[0022] In this embodiment, as Figures 2-4As shown, the second servo motor 47 drives the bidirectional threaded rod 46 to rotate, and the two moving blocks 44 slide synchronously in opposite directions under the limitation of the dovetail groove 11. The connecting rod 43 pushes and pulls the rotating frame 32 accordingly, causing the rotating shaft 33 and the traveling wheel 34 mounted on it to swing up and down relative to the positioning frame 14. When the traveling wheel 34 swings down to the lowest position, the first servo motor 35 drives the rotating shaft 33 to rotate, and the traveling wheel 34 rolls in contact with the workpiece surface. The laser head 1 is pulled forward at a uniform speed to achieve continuous line marking. When the traveling wheel 34 swings up to the highest position, the wheel body completely detaches from the workpiece, the bottom surface of the positioning frame 14 directly contacts the workpiece, the laser head 1 loses its driving force, the optical path is fixed, and it switches to static marking. The entire switching process requires no additional tools. A light touch of a button can switch between the "static" and "dynamic" states with one click, meeting the needs of different scenarios.

[0023] The working principle of this utility model is as follows: When operating by hand, the silicone anti-slip sleeve 2 increases grip friction, prevents sweat and slipping; after the support rod 51 is rotated out of the storage slot 121, the roller 52 and the end of the handle 12 form a fulcrum, the force of the laser head 1 shifting forward is balanced by the fulcrum, and the wrist does not need to press down continuously to keep the whole machine stable. When continuous marking is required, the second servo motor 47 drives the bidirectional threaded rod 46 to rotate, and the two moving blocks 44 move synchronously in opposite directions under the guidance of the dovetail groove 11. The rotating frame 32 is pushed and pulled by the connecting rod 43, so that the traveling wheel 34 swings down to a position lower than the bottom surface of the positioning frame 14. At this time, the first servo motor 35 drives the rotating shaft 33 to rotate, and the traveling wheel 34 rolls in contact with the surface of the workpiece. The entire laser head 1 is pulled at a uniform speed, and the optical path maintains a constant power output during the movement, forming continuous marks with consistent depth and smooth lines. When fixed-point marking is required, the second servo motor 47 rotates in the opposite direction, the moving block 44 drives the connecting rod 43 to swing the rotating frame 32 upward, the walking wheel 34 lifts away from the workpiece, the bottom surface of the positioning frame 14 directly contacts the surface of the workpiece, the laser head 1 loses its traveling power, and the optical path continues to output at a fixed position to complete the static marking. The two modes can be switched with the same button without the need for additional tools or disassembly of any parts. After the operation is completed, the support rod 51 is retracted into the storage slot 121, and the walking wheels 34 can also be reset to the high position. The overall size of the machine is compressed, and it can be stored upright or put into a tool bag, achieving true lightweight, non-slip, and handheld dual-mode laser marking.

[0024] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
