Embodiment 1

[0027] The laser engraving process of magnesium aluminum panels for notebook computers includes the following steps:

[0028] The magnesium-aluminum parts formed by CNC form a primer on the surface of the magnesium-aluminum part. The thickness of the primer is 20-25um. After the primer is dried, laser engraving is performed on it with a laser engraving machine. Choose a laser transmitter with an output power of not less than 50W, and set the output power to 100% of the average output power, 20HZ frequency, 0.03-0.05mm spacing between filling lines, 3000mm / s scanning speed, and 19.89mm carving depth. um.

[0029] After the carving is completed, a topcoat is formed on the surface of the carving, and the thickness of the topcoat is 10-15um.

[0030] Carry out conventional and salt spray tests on the magnesium-aluminum parts after the above-mentioned engraving process. The environment of the salt spray test is a salt solution with a concentration of 5%. The test results are shown...

Embodiment 2

[0039] Basic as attached figure 2 Shown: The difference from Embodiment 1 is that the magnesium-aluminum plate 21 includes a panel body, wherein the panel body includes a magnesium plate 20 and an aluminum plate 21 connected to each other, the area of ​​the magnesium plate 20 is much larger than that of the aluminum plate 21, and the magnesium plate 20 is far away from the aluminum plate 21 Two connection notches are arranged symmetrically on one side, and the connection notches are set close to the side of the magnesium plate 20 , and a plastic plate 22 is arranged in the connection notches.

[0040] The specific connection method between the magnesium plate 20 and the aluminum plate 21 is that a number of irregular first grooves 23 are arranged on the side of the aluminum plate 21 close to the magnesium plate 20, and the number of first grooves 23 are distributed along the side spacing of the aluminum plate 21. , while a number of irregular first protrusions are correspondi...

Abstract

The invention relates to the technical field of laser engraving processes, and particularly discloses a laser engraving process of a magnesium-aluminum panel for a notebook computer. The laser engraving process comprises the following steps of 1, forming priming paint with the thickness of 20 to 25 microns on a magnesium-aluminum part formed through CNC; 2, carrying out laser engraving treatment on the priming paint in the step 1, wherein the engraving depth does not exceed 20 microns, and the power of a laser engraving machine used is not lower than 50 W; and 3, forming finish paint on the carved surface in the step 2. According to the laser engraving process, a magnesium-aluminum metal bottom plate cannot be damaged, and compared with a traditional process that engraving is conducted onthe magnesium-aluminum part firstly and then the priming paint and the finish paint are brushed, on one hand, the metal bottom plate can be damaged, and on the other hand, after engraving is completed, the priming paint is brushed, so that engraving is filled, the depth cannot meet the requirement, and it is indicated that the granularity is insufficient.

Description

technical field [0001] The invention relates to the technical field of laser engraving, in particular to a laser engraving process for a magnesium-aluminum panel for a notebook computer. Background technique [0002] At present, in the production process of the notebook case, the front of the front panel of the notebook computer is mainly used for arranging keyboard slots and installation lines, while the back needs to be carved to improve the texture of the panel. The current process method is to first mill out the metal Bottom plate, clean the metal bottom plate, then carry out the engraving treatment, and then carry out the primer and topcoat process. In this way, it is found that the primer and topcoat will fill the engraving, which makes the surface texture of the final product insufficient. In order to solve this problem , the existing method is to increase the depth of engraving, so that after the primer and topcoat are painted, the panel can still maintain a good tex...
