Problems solved by technology
[0009] This method is to use mimeograph printing pattern on the transparent film between the real wood layer and the light-transmitting substrate to present light-transmitting. It has not been used in the industry at present, and its disadvantages are: a. mimeograph film layer and substrate and wood The cortex bonding effect is poor, there will be delamination in the later after-sales, and the experimental performance is poor
[0010] In summary, due to the technical difficulties of the previous technologies, they have not been used in the industry at present. This technology can just make up for the above-mentioned technical shortcomings, realize mass production and meet the relevant requirements of the product. Experimental Performance Requirements

Embodiment Construction
[0028] With reference to the accompanying drawings, it can be seen that the technical method of the present invention is specifically implemented as follows:
[0029] a. Select veneer with better light transmission. The types of veneer include basil, Chilean maple, white cork or other veneer with better light transmission, as well as natural veneer or technical veneer that is processed into light transmission in the later stage, etc. The thickness of the veneer can be processed to a thickness of 0.2mm~0.6mm.
[0030] b Bind the light-shielding layer and the film layer together and then carry out pattern or text laser engraving. The light-shielding layer is a braid or veneer with a thickness of about 0.2~0.5mm without light transmission, such as non-woven fabric or wood veneer without light transmission. For materials that can be shading, the light-shielding layer and the film need to be laser penetrated together during laser engraving, and the positioning between the light-shi...

The invention discloses a process technology method for realizing hidden light transmission of a real wood decorating part, which is mainly applied to automobile interior trim parts, steamship interior trim parts and household appliance decorating parts, and aims to improve the value and grade of the real wood interior trim parts, so that customers have higher use and driving experience. In order to solve the related problems that in the prior art, mass production is not high, and related experimental performance does not meet requirements, and the like, the main technological method comprises the steps that light-transmitting wood veneers are selected, laser carving of patterns and characters is carried out after the wood veneers are covered with shading layers, hot press forming is carried out, in-mold injection forming is carried out, polishing and paint spraying are carried out, and light-emitting module assembling is carried out. According to the light transmitting principle, a back light source is projected to the wood veneer through the transparent plastic layer and the laser etching hollowed-out part on the light shielding layer, so that the designed effects of patterns, characters, LOGO and the like are shown on the surface of the wood veneer.
Description
technical field [0001] This invention is a technical method to realize the hidden light transmission effect of real wood decorative parts. The specific effect is that when the light source is not turned on on the back of the part, the front of the part presents a natural veneer texture effect, and the radium carving on the back is completely invisible. Patterns, text and LOGO, but when the light source is turned on on the back of the part, the designed radium-engraved pattern, text and LOGO effect appear on the front of the part, which can be applied to real wood decorative parts in the car (such as instrument panels, door panels, central control panels, etc.) Panels, etc.), real wood decorative parts inside ships and yachts, and real wood decorative parts for home appliances. Background technique [0002] For the existing real wood decorative parts, only the texture and appearance of the veneer are presented through color adjustment and surface painting treatment. In order ...
