Technical Field

The present invention relates to a vehicle decorative plate and a forming method thereof, particularly to a method for processing a pattern display layer of a vehicle curved surface decorative plate by laser engraving.

Background

Referring to fig. 5 to 7, a conventional automobile trim panel, such as a vehicle logo (logo) (a), includes a substrate (a1), a scratch-resistant layer (a2), a display layer (A3), a metal plating layer (a4), a protective paint layer (a5), and a protective cover (a 6).

Wherein, the scratch-resistant layer (A2) is coated on the outer layer of the substrate (A1), and then the pattern of the display layer (A3) is printed by ink on the inner layer of the substrate (A1) in a printing mode of screen printing, pad printing, hot stamping and the like; then, the metal coating (A4) is evaporated or sputtered on the display layer (A3); after the protective paint layer (A5) is coated, the protective cover (A6) is covered. Wherein, the display layer (A3) refers to the part of the substrate (A1) shielded by ink, and the ink of the display layer (A3) can directly display graphics, patterns or characters; alternatively, the display layer (A3) may be a shielding part formed by ink on the substrate (a1), and a non-shielding part on the substrate (a1) may display the metal texture of the metal plating layer (a4), and the metal plating layer (a4) may form a pattern, a pattern or a character.

However, the ink printing method of the display layer (A3) is only suitable for the decoration board with a plane or a micro curved surface, and when the decoration board has a larger curved surface, the ink printing method of the display layer (A3) has the following problems:

1. when screen printing is adopted, curved surface printing, such as concave surface printing, has the problem that patterns cannot be completely transferred to form missing parts, so that when the curvature radius of the concave surface is too large or a special shape is formed, screen printing cannot be adopted.

2. In pad printing, there are problems such as burrs occurring at the boundary of the pattern or broken pattern in the printing, which results in poor appearance of the pattern.

3. When hot stamping is adopted, the problems of poor appearance such as rough edges generated on the boundary of a graph or broken pictures printed are easily caused during curved surface printing. Meanwhile, the hot stamping process makes the substrate undergo a high-temperature and high-pressure process, which easily causes stress and cracking on the curved substrate.

Refer to taiwan patent No. M544436, "automotive interior light-emitting panel", which is a laser engraving method for removing opaque ink portion on a planar automobile decorative panel to engrave a light-transmitting pattern, but is still used for manufacturing the planar automobile decorative panel.

Refer to taiwan patent No. 479120, entitled "manufacturing method of vehicle rearview mirror with indicator light function and vehicle rearview mirror manufactured by the method", which is to spray paint on the mirror shell of the rearview mirror, and then remove part of the paint by laser engraving to form transparent display pattern.

In the prior art, laser engraving is adopted to remove opaque ink or paint, but the quality of the ink or paint may be changed by the high-temperature laser processing process, so that the designed color cannot be presented, and the product quality is different.

The label (logo) (10) comprises a curved substrate (1), an anti-draw layer (2), a display layer (3), a protective paint layer (4) and a curved protective cover (5), wherein:

the curved substrate (1) is transparent or semitransparent and is provided with a convex display surface (11) and an inwards concave back surface (12), the convex display surface (11) of the curved substrate (1) is coated with an anti-scraping layer (2), and after the curved substrate is manufactured, the convex display surface (11) can be exposed in the environment to display the display layer (3), so that the anti-scraping layer (2) is coated on the convex display surface (11) to reduce the abrasion of the surface of the convex display surface (11). Then, a plating layer (30) is coated on the back surface (12) of the inner recess in a way of evaporation or sputtering, then, the unnecessary plating layer is removed by laser engraving to process the plating layer into the display layer (3), the display layer (3) displays the figures, patterns or characters of the logo (logo) (10), wherein the parameters of the laser engraving are corrected according to different metal plating layers, and the laser engraving is a conventional technology and is not repeated herein. Then coating the protective paint layer (4) on the display layer (3) to avoid the display layer (3) peeling off or slow down the oxidation, then combining the curved surface protective cover (5) on the curved surface substrate (1) to cover the display layer (3), the common method is injection or adhesion mode, and the curved surface substrate (1) is transparent or semi-transparent, so as to display the graph, pattern or character of the display layer (3).

Referring to fig. 4, in addition to the display layer (3) being formed on the concave back surface (12) of the curved substrate (1), the display layer (3) may be formed on the convex display surface (11) of the curved substrate (1), for example, in fig. 4, a coating is coated on the convex display surface (11) by evaporation or sputtering, then the coating is processed into the display layer (3) by removing the unnecessary coating by laser engraving, then the protective paint layer (4) is coated on the display layer (3) to prevent the display layer (3) from peeling off or slow down the oxidation of the display layer, and then the curved protective cover (5) is combined on the curved substrate (1) to cover the display layer (3), at this time, the curved protective cover (5) is exposed in the environment to display the display layer (3), thus, the scratch-resistant layer (2) is coated on the curved protective cover (5). At this time, the curved surface protection cover (5) is required to be in a transparent or semitransparent shape so as to display the figures, patterns or characters of the display layer (3).
