Description

Technical Field

[0001] The invention relates to the technical field of laser processing, in particular to a large-format glass drilling and grinding all-in-one machine. Background Art

[0002] Laser sandblasting machine is a processing equipment that uses laser technology to sandblast and drill holes on the surface of materials. Its core principle is to use a high-energy, highly focused laser beam to irradiate the surface of the material, convert light energy into heat energy, and locally melt or vaporize the material, thereby achieving the effect of sandblasting and drilling.

[0003] When sanding or drilling large-format glass, first place the glass plate on the laser sandblasting machine, transport the glass plate through the conveying device on the laser sandblasting machine, transport the glass plate to the bottom of the laser, and then emit laser to sand and drill the glass plate.

[0004] However, during use, as the size of the glass plate increases, the thickness of the glass plate also increases synchronously, requiring the laser to frequently adjust the focus according to the thickness of the glass plate, resulting in low processing efficiency of the laser sandblasting machine.

[0005] To this end, the prior art proposes a method for colorful frosting of metal surfaces. The invention uses a femtosecond laser to mark a clear periodic micro-nano stripe structure on the surface of the metal material; and etches a frosted gradient effect on the metal surface through a nanosecond laser, thereby achieving a frosted effect. However, the problem of frequent focusing required as the thickness of the glass plate changes has not been solved.

When the transmission wheel 64 rotates, it cooperates with the thread on the support column through the screw groove, so that the support rod 65 slides vertically upward. At the same time, because the nominal diameter of the transmission wheel 64 is smaller than the nominal diameter of the auxiliary wheel 63, the rotation speed of the transmission wheel 64 is greater than the rotation speed of the driven wheel 43 and the driving wheel 41, so that the speed of the vertical sliding of the support rod 65 is greater than the sliding speed of the lifting platform 5, so that the support rod 65 slides vertically upward relative to the lifting platform 5; The support rod 65 has a circular sliding cavity 652, and a slider 653 is arranged in the sliding cavity 652.
