[0038] See also Figures 1 to 3 As shown, the embodiment of the utility model provides a laser engraving device 10, which includes a mounting structure 100, a laser assembly 200, a galvanometer assembly 300 and a moving assembly 400; the mounting structure 100 includes a mounting frame 110 and a moving seat 120, the moving seat 120 is movably connected to the mounting frame 110, and the mounting frame 110 is used to connect with an external component; the laser assembly 200 is arranged on the moving seat 120; the galvanometer assembly 300 includes a galvanometer driving member 310 and a galvanometer reflector 320, the galvanometer driving member 310 is connected to the moving seat 120, the galvanometer reflector 320 is connected to the output end of the galvanometer driving member 310, and the galvanometer reflector 320 is arranged on the laser optical path of the laser assembly 200, and the galvanometer driving member 310 is used to drive the galvanometer reflector 320 to rotate relative to the moving seat 120; the moving assembly 400 is arranged on the mounting frame 110 and connected to the moving seat 120, and the moving assembly 400 is used to drive the moving seat 120 to move relative to the mounting frame 110.

[0039] In the laser engraving device 10 of the present embodiment, by setting the galvanometer assembly 300 to cooperate with the laser assembly 200, the direction of the laser emitted by the laser assembly 200 can be automatically adjusted to improve the scanning and cutting speeds, and by setting the moving assembly 400 to cooperate with the mounting structure 100, the position of the laser assembly 200 can be adjusted, the structure is simple, and the use effect is good.

[0040] Specifically, the laser assembly 200 includes a laser 210 and a laser heat sink 220 . The laser 210 is disposed on the movable seat 120 . The laser heat sink 220 is connected to the laser 210 and is used to conduct heat of the laser 210 .

[0041] By arranging the laser heat sink 220 in cooperation with the laser 210 , the heat generated by the laser 210 when started can be conducted to the laser heat sink 220 and dissipated through the laser heat sink 220 to avoid overheating of the laser 210 , thereby improving the operating reliability of the laser assembly 200 .

[0042] In one embodiment, the laser heat sink 220 includes a heat sink 221 and a heat sink fan 222 . The heat sink 221 is connected to the laser 210 and the heat sink fan 222 , respectively. The heat sink 221 is used to transfer the heat of the laser 210 to the heat sink fan 222 .

[0043] In this embodiment, the radiator 221 may have a plurality of heat dissipating fins, and the radiator 221 is preferably mounted on the laser 210 to conduct the heat emitted by the laser 210, and dissipate the heat of the radiator 221 to the external environment through the heat dissipation fan 222. At the same time, the radiator 221 can also achieve passive heat dissipation through the heat dissipation fins. With the assistance of active heat dissipation of the heat dissipation fan 222, the heat dissipation effect of the laser 210 can be effectively improved. When the radiator 221 is mounted on the laser 210, the combined structure of the laser 210 and the laser heat sink 220 can also be made compact and occupy a small space.

[0044] In one embodiment, the rotation axis of the galvanometer driver 310 is parallel to the moving direction of the moving base 120 .

[0045] In this arrangement, when the moving assembly 400 drives the moving base 120 to move in a straight line relative to the mounting frame 110, since the galvanometer driving component 310 drives the galvanometer reflector 320 to rotate along a rotation axis parallel to the moving direction of the moving base 120, the galvanometer reflector 320 can be driven to realize a scanning function on a plane perpendicular to the rotation axis of the galvanometer driving component 310 during the movement of the galvanometer assembly 300, thereby increasing the scanning range of the galvanometer assembly 300, thereby improving the engraving performance of the laser engraving device 10.

[0046] Specifically, the galvanometer assembly 300 further includes a galvanometer pressing block 330 , which is connected to the moving seat 120 , the galvanometer driving member 310 is connected to the galvanometer pressing block 330 , and the galvanometer reflector 320 and the galvanometer pressing block 330 are arranged to rotate relative to each other.

[0047] In this embodiment, the galvanometer clamp 330 can be connected to the movable seat 120 and serve as a fixed structure of the galvanometer driver 310. At this time, the galvanometer driver 310 is connected to the galvanometer clamp 330, and the galvanometer reflector 320 can be rotatably connected to the galvanometer clamp 330 to limit the rotation of the galvanometer reflector 320.

[0048] In one embodiment, the galvanometer assembly 300 further includes a galvanometer fixing seat 340 . The galvanometer fixing seat 340 is connected to the moving seat 120 . The galvanometer reflector 320 is movably disposed in the galvanometer fixing seat 340 .

[0049] Thus, when assembling the galvanometer assembly 300, first install the galvanometer fixing seat 340 on the moving seat 120, then insert the galvanometer driving member 310 into the galvanometer pressing block 330 and connect it to the galvanometer reflector 320, then place the galvanometer reflector 320 into the galvanometer fixing seat 340 and connect it to the moving seat 120 through the galvanometer pressing block 330, thereby connecting and fixing the galvanometer pressing block 330 and the galvanometer fixing seat 340 to the moving seat 120, which has a simple structure and is easy to assemble. At the same time, after the galvanometer pressing block 330 is sealed and connected to the galvanometer fixing seat 340, the galvanometer reflector 320 can also be protected to achieve dustproof and anti-collision functions.

[0050] Specifically, the moving component 400 includes a moving motor 410, a moving screw rod 420 and a moving transmission block 430. The moving motor 410 is connected to the mounting frame 110, the moving screw rod 420 is connected to the output end of the moving motor 410, the moving transmission block 430 is connected to the moving seat 120, and the moving transmission block 430 is transmission-connected to the moving screw rod 420.

[0052] In one embodiment, the moving assembly 400 further includes a moving rail 440 and a moving slider 450 . The moving rail 440 is slidably connected to the moving slider 450 . The moving rail 440 is disposed on the mounting frame 110 , and the moving slider 450 is connected to the moving seat 120 .

[0053] By providing a movable guide rail 440 and a movable slider 450 to connect the mounting frame 110 and the movable seat 120 , the movement of the movable seat 120 relative to the mounting frame 110 can be guided to improve the smoothness of the movement of the movable seat 120 relative to the mounting frame 110 .

[0054] Furthermore, the moving assembly 400 further includes a moving sensing switch 460 and a moving sensing rod 470 . The moving sensing switch 460 is disposed on the mounting bracket 110 . The moving sensing rod 470 is connected to the moving seat 120 , and the moving sensing rod 470 is used to contact the moving sensing switch 460 .

[0055] Thus, when the movable seat 120 moves to the end of the path relative to the mounting frame 110 , the movable sensing rod 470 can contact the movable sensing switch 460 to trigger the movable sensing switch 460 , thereby obtaining the position signal of the movable seat 120 through the movable sensing switch 460 .
