Abstract

A laser engraving and multi-color processing technique comprises the following steps to be performed in a factory: 1. punching and molding an aluminum material; 2. polishing a surface of the aluminum material; and 3. anodizing and brightening the aluminum material, and processing the same to obtain a high-gloss surface; and further comprises the following steps to be performed in a retail store: 4. inputting a personalized pattern into a computer; 5. engraving the personalized pattern on the high-gloss surface by means of a laser engraving machine; 6. applying ink onto the engraved personalized pattern; and 7. wiping off excess ink from the high-gloss surface after the ink is dry. The present technique is partly implemented in the factory and partly implemented in the retail store, thereby meeting the requirements of speedy processing of personalized signatures and patterns in the retail store. Moreover, the technique is simple to implement, does not involve toxic and harmful substances, and facilitates speedy manufacture and delivery of finished products.

Description

Laser engraving multi-color processing technology

Technical field

The invention belongs to the technical field of product surface treatment, in particular to a laser engraving multi-color processing technology.

Background technique

With the general increase in people's personalized needs, it is very common to engrave personalized patterns and signatures on personal items, which are widely used in industrial production and cosmetic personalized signatures, handicraft signatures and other fields. For example, there are demands on mobile phone shells, various electronic product shells, and decorative shells. In the existing technology, the general engraving process is generally completed in the factory, and the engraving is carried out in batches, which is difficult to meet the personalized retail order requirements for rapid production of pickups, and the existing order is generally pure laser engraving, engraving The color of the back pattern or signature is the color of the metal itself, which is difficult to meet the needs of personalized colors. At present, when processing in the factory, if you need to meet the requirements of multi-color processing, you generally need to use a lot of toxic and harmful chemicals that are difficult to control.

Summary of the invention

In view of the shortage of the existing technology, the present invention provides a laser engraving multi-color processing technology. Part of this processing technology is completed in the factory, and the other part can be completed in the retail store to meet the needs of rapid processing of individual signatures and patterns in the retail store. , And the operation is simple, non-toxic and harmless, quickly make pickups.

In order to solve the above technical problems, the present invention is solved by the following technical solutions: a laser engraving multi-color processing process, including the following steps completed in the factory: 1, the aluminum material is punched into shapes; 2, the aluminum surface Polishing; 3. Anodizing and brightening the aluminum material to process the high-gloss surface; also including the following steps completed in the retail store: 4. Entering the personalized pattern into the computer; 5. Using the laser engraving machine on the high-gloss surface Carve out personalized patterns; 6. Apply ink to the carved personalized patterns; 7. Wipe off excess ink on the high gloss surface after the ink is dry. Using this laser engraving multi-color processing technology, the high-gloss surface is processed in the factory, and then the ink is painted on the high-gloss surface by the laser engraving machine in the retail store. After the ink is dried, it can be very convenient to wipe the high-gloss surface The ink on the surface is erased, and because the engraved position has a strong adsorption capacity for the ink, it will not be erased. Part of this processing process is completed in the factory, and the other part is completed in the retail store, which can meet the needs of fast retail stores. The processing of personalized signatures and patterns is required, and the operation is simple, non-toxic and harmless, suitable for retail power supply operation, and can quickly produce pickups.

In the above technical solution, preferably, the ink in step 6 is a self-drying ink. The use of self-drying ink allows the ink to dry faster, resulting in shorter processing time, improved processing efficiency, and the need for quick parts pickup.

In the above technical solution, preferably, a step of drying the ink by a blower is also included between step 6 and step 7. Drying the ink through a blower makes the processing time shorter and the processing efficiency improved to meet the demand for fast parts pickup.

In the above technical solution, preferably, after step 3 completed in the factory, it also includes sandblasting the high-gloss surface, and then performing anodizing treatment again. Sandblasting and anodizing treatment can further improve the smoothness of the high-gloss surface, making subsequent ink easier to wipe off.

In the above technical solution, preferably, in the second anodizing treatment, the electrolytic polishing time is 3 to 5 minutes.

Compared with the prior art, the present invention has the following beneficial effects: using this laser engraving multi-color processing technology, a high-gloss surface is processed in a factory, and then ink is printed on the high-gloss surface in a retail store by a laser engraving machine , Wiping after the ink is dry can easily erase the ink on the high-gloss surface, and because the engraved position has a strong adsorption capacity for the ink and will not be erased, part of this processing process is completed in the factory. And the other part is completed in the retail store, which can meet the needs of rapid processing of personal signatures and patterns in the retail store, and is simple to operate, non-toxic and harmless, suitable for retail power supply operation, and can quickly produce pickups.

detailed description

The present invention will be described in further detail below with reference to specific embodiments: a laser engraving multi-color processing process, including the following steps completed in the factory: 1. Punching aluminum material into shapes; 2. Polishing aluminum surface; 3 1. Anodizing and brightening the aluminum material to process the high-glossy surface, sandblasting the high-glossy surface, and then performing anodizing treatment again. In the second anodizing treatment, the electrolytic polishing time is 3 to 5 minutes; Including the following steps completed in the retail store: 4. Enter the personalized pattern into the computer; 5. Engrave the personalized pattern on the high-gloss bright surface through the laser engraving machine; 6. Apply the self-drying ink on the engraved personalized pattern , Dry the ink through a blower; 7. After the ink is dry, wipe off the excess ink on the high-gloss surface. Using this laser engraving multi-color processing technology, the high-gloss surface is processed in the factory, and then the ink is painted on the high-gloss surface by the laser engraving machine in the retail store. After the ink is dried, it can be very convenient to wipe the high-gloss surface The ink on the surface is erased, and because the engraved position has a strong adsorption capacity for the ink, it will not be erased.
