The surface of the piece is patterned, or the workpiece is cut. In the past, when the laser engraving machine was processed, because the laser beam was processed on the surface of the workpiece, the surface material of the workpiece was vaporized by high heat to remove the substance that was vaporized. It has become a myriad of dust particles that are scattered inside the laser engraving machine or attached to the surface of the workpiece. Long-term downtime often causes the internal parts of the laser engraving machine to cause corrosion or damage due to the adhesion of too many dust particles on the surface. In order to solve such problems, the current laser engraving machine mainly uses the method of vacuum discharge to remove the dust generated by the vacuum engraving machine from the inside of the laser engraving machine. The main purpose is that the laser engraving machine is arranged inside a sealed outer casing body, and an exhaust pipe is connected outwardly, and the exhaust pipe is connected with a dust collecting device M300583, so that the air is extracted and pushed away.

A schematic diagram of a preferred embodiment of a laser engraving machine is created. As shown in the figure, a preferred embodiment of the laser engraving machine of the present invention mainly has an outer casing 10, and a laser processing device 20 and a carrying device 30 are disposed inside the outer casing 10 to form the >; The structure of the laser engraving machine. Referring to Fig. 2, there is shown an exploded perspective view of a laser processing apparatus and a carrying device according to a preferred embodiment of the present invention. The laser processing apparatus 20 includes a sliding group 22, a laser optical mirror holder 24, and a dust collecting assembly 26. The sliding group 22 has a first sliding rail 222 and two second sliding gates 224. The second sliding gates 224 are arranged in parallel with each other. The first sliding rails 222 are disposed on the second sliding rail 224 in a straight manner. The first slide rail 222 can be moved along the second slide rail 224 by being driven by a driving device (not shown). M300583 Please refer to FIG. 3 and FIG. 4, which are schematic perspective views and motion diagrams of a laser optical lens holder according to a preferred embodiment of the present invention. The laser optics mount 24 is primarily used to generate a laser beam 244 for processing a workpiece 40. The laser optics mount 24 is disposed on the first slider 222 of the set of slides 22 such that the laser optics mount 24 can be moved along the first slide 222. Therefore, by the driving of the slide group 22, the laser lens holder 24 can be moved to an appropriate position along the X-axis (left-right direction) or the ¥-axis (front-rear direction), and the workpiece 40 can be processed. . A main feature of the present invention is that the laser processing unit 20 is provided with a dust collecting assembly 26. The dust collecting assembly 26 includes a suction pipe body 262, a duct 266, and a dust collector 268.

The front end opening of the suction pipe body 262 is located at a position corresponding to the laser beam 244; the end of the suction pipe body 262 is sleeved with a pipe 266, and is connected to the dust collector 268 via a pipe. The dust collector 268 creates a vacuum in the conduit 266 so that a suction force can be generated at the front end of the suction pipe body 262. When the laser optical body 24 generates the laser beam 244 to process the workpiece 4, the suction pipe body 262 can heat the surface of the workpiece 40 by the laser beam 244 to vaporize the dust particles. The position where the laser beam is placed (above the processing site) is immediately extracted and removed, so that the dust particles do not have a chance to enter the interior of the laser engraving machine. The extracted dust particles are sent to the dust collector 268 through the conduit 266 for filtration and collection; and the clean air after the dust particles have been filtered is discharged out of the dust collector. In this way, the dust particles generated during processing are prevented from being scattered inside the housing M300583 ~ ίο outside the laser engraving machine to avoid erosion or damage to the internal parts. Please refer to FIG. 5 and FIG. 6 for a perspective view of the working platform and the positioning component of a preferred embodiment of the present invention and a combination thereof. The carrier device 30 is disposed below the laser processing device 20. The carrier device 30 includes a flat working platform 32 and a positioning member 34. The surface of the working platform 32 has at least one long straight guiding groove 36, and a symmetric convex edge 362 is protruded from the opposite side walls of the groove 366 on the surface of the guiding groove 36, so that the positioning element 34 can be along The guide groove 36 moves in the direction of the guide groove 36 and is positioned inside the guide groove 36.

The screw hole 346 is provided with a screw 348. When the positioning member 34 is disposed inside the guide groove 36 via the receiving groove 364, the fixing plate 342 can be moved in the up and down direction by adjusting the rotation of the screw 348. After the positioning member 34 is adjusted to the proper position inside the guide groove 36, the screw 348 can be adjusted so that the fixing plate 342 can be lifted upward to abut against the flange 362 of the guide M300583 groove 36, so that the fixing member 34 is The flanges 362 of the guide groove 36 are in a forced state, thereby achieving the purpose of locking and fixing the positioning member 34: When the positioning component 34 is to be adjusted to other positions, it is only necessary to adjust the screw 348 to move the fixing plate 342 downward, so that the positioning component 34 is in a loose state (as shown in FIG. 8). ), the positioning element 34 is easily moved inside the guide groove 36 and adjusted in position.
