Laser mapping process for frosted transparent glass ornament surface

Abstract

The present invention discloses a laser mapping process for the surface of frosted transparent glass ornaments, comprising the following steps: step 1, cleaning the surface of the crystal glass ornaments; step 2, frosting the cleaned crystal glass ornaments; step 3, stringing the frosted crystal glass ornaments into strips, cleaning the surface, and drying; step 4, vacuum coating the dried crystal glass ornaments; step 5, using a laser machine to engrave and map the surface of the vacuum-coated crystal glass ornaments; step 6, completing laser mapping, and removing the crystal glass ornaments. The coating layer is ablated by laser, and after the coating layer on the surface of the glass ornament is peeled off, the frosted surface prevents the laser from passing through the glass ornaments, or the penetrating laser is not enough to peel off the bottom coating layer. The glass ornaments can be rotated to produce double-sided or multi-sided patterns. After vacuum coating, the laser can only peel off the surface coating layer. The glass ornaments can be rotated to produce double-sided or multi-sided patterns.

Description

Technical Field

[0001] The invention relates to a drawing process, and more specifically to a laser drawing process for the surface of a frosted transparent glass ornament. Background Art

[0002] Since December 2017, our glass ornaments have been vacuum coated to form a colored film on the surface, and then laser engraved to form a colored pattern. This method previously required the use of porcelain glass (emulsified glass). For transparent glass ornaments, the laser will penetrate the glass ornaments and peel off the colored film layer on the surface and bottom, making it difficult to form double-sided or multi-sided patterns. For this reason, after repeated research and experiments, our company proposed that glass ornaments should be frosted first, then vacuum coated and laser engraved, so that double-sided or multi-sided patterns can be formed. Summary of the invention

[0003] The main technical problem solved by the present invention is to provide a laser patterning process for the surface of frosted transparent glass ornaments, which overcomes the problem that double-sided or multi-sided patterns cannot be formed on transparent glass ornaments in the past.

[0004] In order to solve the above technical problems, the present invention relates to a mapping process, more specifically, a laser mapping process for the surface of a frosted transparent glass ornament, characterized in that it comprises the following steps:

[0005] Step 1: Clean the surface of the crystal glass ornaments;

[0006] Step 2: Frost the cleaned crystal glass ornaments;

[0007] Step 3: string the frosted crystal glass ornaments into strips, clean the surface, and then dry them;

[0008] Step 4, vacuum coating the dried crystal glass ornaments;

[0009] Step 5: Use a laser machine to carve and map the surface of the vacuum-coated crystal glass ornaments;

[0010] Step 6: Complete laser mapping and remove the crystal glass ornaments.

[0011] Furthermore, the frosting process in step 2 is one or a combination of diamond abrasive vibration treatment, mechanical sandblasting, manual grinding or hydrofluoric acid etching.

[0012] Furthermore, the glass ornament rotates or turns during laser engraving.

[0013] The beneficial effects of the laser mapping process for the surface of frosted transparent glass ornaments of the present invention are:

[0014] The present invention discloses a frosted transparent glass ornament surface laser mapping process, which uses laser ablation of the coating layer. After the coating layer on the surface of the glass ornament is peeled off, the frosted surface prevents the laser from penetrating the glass ornament, or the penetrating laser is insufficient to peel off the bottom coating layer. By rotating the glass ornament, double-sided or multi-sided patterns can be produced. To achieve this effect, we frosted the surface of the transparent glass ornament. After vacuum coating, the laser can only peel off the surface coating layer. By rotating the glass ornament, double-sided or multi-sided patterns can be produced. DETAILED DESCRIPTION Example

[0015] The following steps are involved:

[0016] Step 1: Clean the surface of the crystal glass ornaments;

[0017] Step 2: Frost the cleaned crystal glass ornaments;

[0018] Step 3: string the frosted crystal glass ornaments into strips, clean the surface, and then dry them;

[0019] Step 4, vacuum coating the dried crystal glass ornaments;

[0020] Step 5: Use a laser machine to carve and map the surface of the vacuum-coated crystal glass ornaments;

[0021] Step 6: Complete laser mapping and remove the crystal glass ornaments.

[0022] The frosting process in step 2 is one or a combination of diamond sand vibration treatment, mechanical sandblasting, manual grinding or hydrofluoric acid dissolution.

[0023] When laser engraving, the glass ornaments are rotated or turned over to create double-sided or multi-sided patterns.

[0024] After the laser peels off the coating layer on the surface of the glass ornament, the frosted surface prevents the laser from penetrating the glass ornament, or the penetrating laser is not enough to peel off the bottom coating layer. By rotating the glass ornament, double-sided or multi-sided patterns can be made. To achieve this effect, we frosted the surface of the transparent glass ornament. After vacuum coating, the laser can only peel off the surface coating layer. By rotating the glass ornament, double-sided or multi-sided patterns can be made.

[0025] Transparent glass ornaments have many colors. After vacuum coating, the surface coating color and the original color of the glass ornaments can be freely combined, and the pattern colors are very rich. It has changed the original use of opaque porcelain glass ornaments for surface drawing. There are many glass materials to choose from, rich products, and beautiful appearance. It has achieved a leap from coating the surface of transparent glass ornaments with colored films to making colored patterns on the surface.

[0026] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
