[0028] It should be noted that by setting placement groove 2 on engraving table 1, engraving material 19 is placed in placement groove 2, after engraving material 19 is placed, first, the auxiliary positioning assembly is used to pre-position engraving material 19, then vacuum pump 5 is started to extract a part of the gas in negative pressure chamber 3, after the air is reduced, negative pressure chamber 3 will suck the bottom of engraving material 19 tightly on rubber pad 9, thereby maintaining the firmness of engraving material 19, so that laser generator 8 will not cause the offset of engraving material 19 in engraving, and the stability of engraving is improved.

[0029] In this embodiment, the front end of engraving table 1 is provided with support plate 6, the side of support plate 6 close to engraving table 1 is provided with control box 7 of external power supply, control box 7 is movably connected to support plate 6, and the bottom of control box 7 is provided with laser generator 8.

[0030] It should be noted that the printing method used in the utility model is a laser printing method, and the working principle of the laser printing machine is based on the principle of laser and material interaction, specifically, when a high-energy-density laser beam irradiates the material surface, a series of physical and chemical effects such as vaporization, combustion, etc. will occur, thereby forming a specific pattern or character on the material surface, and the control box 7 is responsible for controlling the laser generator 8, thereby enabling the laser generator 8 to emit laser, and there are beam expander mirrors, full-reflecting half-reflecting mirror pieces, focusing mirrors and other optical elements in the controller, which are used to focus, shape and guide the laser beam generated by the laser generator 8, so as to ensure that the laser beam can accurately irradiate the material surface on the workbench.

[0031] The laser generator 8 generates a laser beam, which is focused and shaped by the optical system to form a micron-level light spot, and when the laser beam irradiates the material surface, the laser energy is absorbed by the material and converted into heat energy, and with the accumulation of heat energy, the temperature of the local area of the material surface rises to reach the threshold of vaporization or combustion, and the substance in the local area of the material surface is vaporized or combusted to form a pit or a scratch,

[0032] The above is the working principle of the laser printing machine, which is prior art and will not be described in detail here.
