Laser light-transmitting piece

Technical Field

The utility model relates to an automobile parts production technical field especially relates to header board gadget.

Background

With the rapid development of industry, the requirement of people on the decoration of vehicles is continuously improved, the application of plastic electroplating is increasingly wide, the plastic electroplating is one of important means of surface decoration in plastic products, and the pursuit of people on automobile ornaments is more and more diversified. Many ornaments on automobiles, including interior ornaments, exterior ornaments and the like, adopt a chromium plating process. Because the chromium plating layer has strong passivation capability in air, bright white color and good durability, higher hardness, scratch resistance, heat resistance, chemical corrosion resistance and excellent weather resistance, the hydroelectric chromium plating is the preferred scheme of the chromium plating decorative strip of the automobile ornament at present. The automobile instrument panel ornament is an important ornament on an automobile, and the color and the style of the existing automobile instrument panel ornament are single, so that the pursuit of consumers for the automobile appearance cannot be met.

Therefore, it is an urgent need to solve the above-mentioned problems by those skilled in the art to improve the existing automobile dashboard decorating parts.

As an improvement, a plurality of light-transmitting bulges extend upwards from the light-guiding plastic substrate, and the light-transmitting bulges are positioned below the laser transmission grating grids. The light-transmitting bulge is arranged to serve as a light guide strip structure on one hand, so that the light-transmitting effect is better; on the other hand, the thickness of the plastic substrate electroplated at the light-transmitting bulge is smaller, so that the laser transmission grating is convenient to process.

As an improvement, one end of the electroplated plastic base material extends downwards to form a scarf joint part, and the scarf joint part is jointed with the end part of the light guide plastic base material. The setting of scarf joint portion makes the combination of electroplating plastic substrate and leaded light plastic substrate more firm reliable.

Preferably, isosceles right triangle light holes are arranged on two sides of the laser light transmission grating, and square light holes are arranged on the inner side of the laser light transmission grating. The above structure is designed mainly in consideration of beauty.

Preferably, the electroplating plastic substrate adopts ABS material. ABS is an acrylonitrile-butadiene-styrene copolymer material.

Preferably, the light-guiding plastic substrate is PC. PC is polycarbonate material.

Preferably, the number of the laser transmission grating grids is three, and the laser transmission grating grids are distributed on the electroplating plastic base material at equal intervals; the light-transmitting protrusions are three corresponding to each other and are distributed on the electroplating plastic base material at equal intervals.

Compared with the prior art, the utility model discloses technical scheme's advantage lies in:

1. the workpiece which can be electroplated and can conduct light and is provided with the light transmission groove (namely the laser transmission grating) is manufactured by a double-color injection molding process, so that the assembly is reduced, the assembly gap error is avoided, the process is simplified, and the working hours and the materials are saved.

2. And engraving a guide grating lattice with regular shape and texture and small gaps on the electroplating surface (the finger electroplating layer and the electroplating plastic substrate) by using a five-axis laser engraving machine.

Specifically, the electroplated layer is attached to the electroplated plastic base material through an electroplating process, and the electroplated plastic base material is embedded with the light-permeable light-guiding plastic base material through a two-color injection molding process, so that reliable and steady bonding strength is achieved, and uniform light-permeable parts, namely the base material of the laser transmission grating, are formed. The high strength and high temperature stability of the light guide plastic base material ensure that the light guide plastic base material is not plated and deformed in the electroplating process, and the binding force between parts is not reduced. After electroplating, laser engraving is carried out to form laser transmission grating grids, so that uniform appearance and lamplight effects are achieved.
