Method and device for engraving three-dimensional image on glass with regular cambered surface

Abstract

The invention discloses a method and device for engraving a three-dimensional image on glass with a regular cambered surface. The method includes the process of using a laser focusing method for forming a damage point in the glass with the regular cambered surface and the process of moving a laser focusing point in the glass with the regular cambered surface, wherein the distance between the glass and the laser focusing point is adjustable, the laser focusing point engraves different regions in the circumferential direction of the glass by means of rotation of the glass, and the laser focusing point moves up and down to engrave different regions in the length direction of the glass; the engraving process is finished through the corresponding device according to the method. Three-dimensional image engraving on drum-shaped or cylindrical glass can be finished, three-dimensional image engraving has wider development space, and the requirement for market diversification is met.

Description

technical field [0001] The present invention relates to an optical device, in particular to an automatic control device, especially to a laser energy-concentrating processing device, and in particular to a method and device for engraving a three-dimensional image in glass with a regular arc surface. Background technique [0002] Crystal and glass laser engraving machine is a machine used for crystal and glass engraving. The main working process is to put the crystal or glass on the workbench of the machine, and output three-dimensional or plane patterns through computer control. Using the principle of laser focus, in Engraved designs inside crystal or glass. [0003] In the prior art, lasers are used to engrave three-dimensional images inside glass, and the surface to be engraved needs to be flat, that is, most of them are engraved in flat glass, so there are great limitations, and many cylindrical objects cannot achieve 360° Spend a week engraving, such as cylindrical glas...
