Problems solved by technology

[0003] In order to engrave crystals of various sizes, the laser head or galvanometer is set to be movable, but later practice found that there are some disadvantages, such as the instability of the laser light path and the insufficient stability of the power, resulting in crystal and glass engraving. The effect is not good, the pattern splicing produces misalignment

Embodiment

[0024] Embodiment: A method for engraving a three-dimensional pattern in glass, including a process of forming a damage point in the glass by using a laser focusing method, and also including a process of moving the glass to make the laser focus point engrave it.

[0025] Specifically, before the laser forms the first damage point in the glass, a glass displacement path range is first set, and in the process of setting the glass displacement path range, the engraved area is divided into one or More than two parallel engraving partitions, any one of the engraving partitions is composed of at least one plane and the outer surface of the glass, any one of the above-mentioned planes forms an angle less than or equal to 90 degrees with the X-Y axis plane, and any phase The adjacent planes are all parallel to each other. In the process of forming the damage point by laser focusing method, the glass is first moved so that the first engraved partition reaches below the laser focus poin...

Abstract

The invention discloses a method and device for engraving three-dimensional patterns in glass. An area to be engraved is divided into one or two or more parallel engraving divided areas; firstly, the glass is moved to enable the first engraving divided area to reach the position below a laser focusing point, and the glass motion is controlled to enable the laser focusing point to engrave the portion, between 1percent to 100percent of a pattern in the first engraving divided area; then the glass is moved in a parallel manner to enable the engraving divided area close to the first engraving divided area to reach the position below the laser focusing point, and the glass motion is controlled to enable the laser focusing point to engrave the portion, between 1percent to 100percent of the pattern in the engraving divided area close to the first engraving divided area; then, the glass is moved to enable the next divided area to each the position below the laser focusing point, and the engraving steps are repeated until the complete pattern is engraved. A laser source and a galvanometer are arranged to be in fixed state, and a working table carrying the glass is arranged to be in a movable type, so that laser vibration is reduced; and the laser focusing point is more stable, and the engraving effect is improved.

Description

technical field [0001] The invention relates to the technical field of laser internal engraving, in particular to a method and device for engraving three-dimensional patterns in glass with stable optical path and good engraving effect. 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 order to engrave crystals of various sizes, the laser head or galvanometer is set to be movable, but later practice found that there are some disadvantages, such as the instability of the laser light path and the insufficient stability of the power, resulting in crystal and glass engraving. The effect is not good, and the pattern splicing produces misalignment. Contents...
