Problems solved by technology

[0005] However, the second method has several disadvantages: firstly, it is only suitable for the incident surface of the material to be a regular surface
Due to the difference in workpiece size error, it is quite difficult to locate some irregular workpieces on the lower surface
Moreover, when the method in the above-mentioned patent is internally engraving a large-volume workpiece, because the transparent liquid needs to flow over the workpiece, when the internal engraving is completed and the workpiece is taken out, some transparent liquid will inevitably adhere to the workpiece, which will consume a relatively large amount of transparent liquid material
If the internal engraving machine itself is a moving platform structure, the inertia of the entire moving platform will be too large during work, which will affect the positioning accuracy and even exceed the design load of the moving platform

Embodiment 1

[0027] When the laser incident surface of the inner engraving workpiece is non-planar, the inner engraving device such as figure 1 As shown, it mainly includes a container 1 with a transparent bottom, which is an open container, and the material at the bottom of the container is a transparent glass plate with a thickness of 10mm. Above, the angle between the optical axis of the convex lens and the bottom of the container is 90°, and the focus of the convex lens and the container 1 can move relative to each other in three dimensions. Use more than two stoppers 3 with the focus as a reference, position the pattern to be engraved relative to the workpiece 3, i.e. the bottle position in this embodiment, and fix it in the container; then inject the transparent liquid into the container to adjust the position of the bottle in the container. The height of the liquid level of the transparent liquid. The minimum height of the liquid level must ensure that the laser incident surface wit...

Embodiment 2

[0029] Such as figure 2 As shown, the present invention also provides another device. When the laser incident surface of the inner carving workpiece is a plane, the device mainly includes a transparent smooth flat plate 6, which is a transparent glass flat plate with a thickness of 10mm. The transparent and smooth flat plate is set above the laser converging mechanism 5 of the laser engraving machine, that is, the convex lens, so that the angle between the optical axis of the convex lens and the transparent and smooth flat plate is 90°, and the focal point of the convex lens and the transparent and smooth flat plate can move relative to each other in three dimensions; Use more than two limit blocks 3 with focus as a reference, position according to the position requirements of the pattern to be engraved relative to the workpiece 3, fix it on a transparent and smooth flat plate 6, and then place the workpiece between the limit blocks so that it relies on the limit Three-axis p...

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a method and a device for realizing internal engraving in transparent materials. Background technique [0002] Laser engraving is a laser beam that is focused inside a transparent object, and its focal point forms a burst point or a colored point. In the existing laser engraving method, the optical axis of the outgoing light of the focusing lens is generally installed perpendicular to the horizontal plane, and the focal point is located under the focusing lens. The placement of materials generally has the following methods. [0003] 1. Select the smooth plane side of the material to be engraved as the incident surface of the laser and fix the incident surface on the platform perpendicular to the optical axis. [0004] 2. If the laser incident surface of the material is non-planar, add a piece of material with a refractive index close to the laser incident surface, th...
