Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the ultra environment-friendly interior graphic display process of the present invention comprises the following steps:

s2, performing laser engraving with consistent engraving depth on the nickel pre-plating composite layer by using a laser engraving device, wherein the laser power is kept at 6W in the engraving process;
s3 is a step of plating the laser engraved position and its periphery.
In the step S1 in the graph display process, electroplating nickel on the surface of an ABS substrate to form an electroplated nickel layer, wherein the ABS substrate is selected mainly based on the fact that the ABS material has the characteristics of strong impact resistance, scratch resistance, stable dimension and the like, and has the characteristics of moisture resistance, corrosion resistance, easiness in processing and the like, the ABS material is made of environment-friendly chemical substances, has no toxicity or peculiar smell, and ensures the environmental protection and safety in the production and processing processes of the ABS substrate; in addition, because the electroplated nickel has extremely fine crystals and excellent polishing performance, the polished nickel-electroplated composite layer can obtain mirror-like gloss appearance, and the polished nickel-preplated layer can keep the gloss in the atmosphere for a long time; in addition, the hardness of the nickel-preplating composite layer is also higher, so that after nickel-preplating treatment, the wear resistance of the surface of the interior product can be improved, the thickness of the nickel-preplating composite layer is preferably 1-2um, a pattern with a certain thickness can be formed on the nickel-preplating composite layer after subsequent laser engraving, a certain concave feeling is formed at the position of the pattern through electroplating treatment, the quality of the interior product is improved from the visual feeling and the touch feeling, and the product shown in fig. 11 is obtained.
In step S2, the nickel precoated composite layer is engraved by a laser engraving device to form an engraved pattern. The laser engraving for electroplating is a surface treatment process by using laser, and the surface layer of an object is chemically changed by using the laser beam, so that the mark is engraved to display the required pattern and characters. In the process, laser is irradiated on the nickel pre-plating composite layer, the nickel of the pattern nickel pre-plating composite layer is carbonized by utilizing the chemical reaction of laser energy and air, and the displacement of a laser source changes, so that the image slowly forms a complete image from a plurality of carved lines. The laser power is 6W, so that a proper amount of nickel can be ensured to react, clear patterns can be formed on the composite layer, the ABS base material is prevented from being influenced by overlarge energy, and the clear patterns cannot be formed due to the reaction of a small amount of nickel when the energy is overlarge.

In step S3, the product engraved by the electroplating laser is electroplated, and since the nickel at the pattern position is carbonized and cannot conduct electricity, the pattern position will show the original color of the substrate and will have a concave feeling because there is no electroplated layer after the electroplating is completed. Because the scales are consistent in the step S2, the patterns are uniformly and consistently sunken, the electroplated patterns are clear, the completeness of the electroplated surface is ensured, and the quality of the product in the aspects of touch and vision is improved.
According to the graphic display process, the interior trim is processed by utilizing the electroplating laser engraving technology, the pattern can be formed on the surface of the base material without paint, the environmental protection is facilitated, the operation is convenient, the laser engraving nick depth is consistent, the appearance of the electroplated graphic is ensured to be attractive, the uniform and consistent sunken feeling is realized, and the precision of the automobile interior trim graphic and the quality of the product are improved in the aspects of vision and touch.

When the laser engraving device of the embodiment is used, firstly, the interior 6 is placed on the base 1, then the template 4 is placed on the interior 6, after the bottom surface of the template 4 is attached to the nickel electroplating composite layer of the interior 6, the lifting mechanism 7 drives the lifting plate 11 to move downwards, the upper clamping plate 17 connected with the upper positioning cylinder 16 below the lifting plate 11 is aligned to the positioning groove 4-1 on the template 4, then the upper positioning cylinder 16 is started, the upper clamping plate 17 extends into the positioning groove 4-1 and abuts against the bottom of the positioning groove 4-1, so that the template 4 is fixed below the lifting plate 11, the lifting cylinder 7a drives the lifting plate 11 to move upwards, the control plane driving mechanism drives the moving block 2 to move, and the laser source 3 performs laser engraving on the interior 6 with consistent scoring depth. When the next interior is to be engraved, the position of the next interior on the base 1 is adjusted in the manner described in example 2. When the interior decorations of different models need to be engraved, the upper positioning air cylinder 16 drives the upper clamping plate 17 to separate from the template 4, so that the template 6 can be conveniently taken down from the lifting plate 11, the template 4 and the lifting plate 11 are detachably connected, the corresponding template 4 can be conveniently installed on the lifting plate 11 according to the interior decorations of different models, and the application range of the laser engraving device is expanded; in the extensible member 5, the universal wheel 5e is used for replacing the ball 5c and the top block 5d, so that the resistance received when the moving block 2 moves can be reduced, and the moving block 2 and the extensible member 5 can move conveniently.
It should be noted that, in the embodiments 3 and 4, only two detachable connection modes of the template 4 are represented, and the template 4 may also be connected with the top plate 10 or the lifting plate 11 in other detachable modes, so that the corresponding template 4 can be conveniently installed on the device according to different interior decorations 6, and the laser engraving device can perform electroplating laser engraving with consistent engraving depth on different types of interior decorations 6.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
