Description
Technical Field
The invention relates to the technical field of artware, in particular to a preparation method for forming a two-dimensional code identification area on the surface layer of a metal jewelry through electroplating and laser engraving and the metal jewelry manufactured by the method.
Background
The two-dimensional code is widely applied to various fields of mass life, and common two-dimensional codes displayed in front of mass are generally manufactured in the modes of printing, displaying by display equipment and directly carving by laser. When the two-dimensional code is required to be marked on the metal surface, the current mainstream preparation method is laser direct marking, and the definition of the two-dimensional code generated by the preparation method is not high. In order to enable scanning and identification, a two-dimensional code with a larger size is usually required to be manufactured, or the contrast of the two-dimensional code is improved, but the contrast in a two-dimensional code area is mainly improved in the prior art, and no one considers that the identifiability of the two-dimensional code is improved by improving the contrast between the edge of the two-dimensional code area and the background color of the metal surface. If a two-dimensional code with a larger size is manufactured, the metal surface occupies a larger area, the contrast of the two-dimensional code is not high, the two-dimensional code is not easy to scan and identify or needs to be scanned and read through specific equipment, the two-dimensional code directly marked by laser can only be used in industrial application, the specific equipment is required to scan and identify, the information of the two-dimensional code can not be read through the scanning and identifying of the civil mobile phone camera equipment, obvious loss is generated on a metal material, particularly noble metal material, the noble metal loss generated by direct laser carving increases the manufacturing cost of a noble metal ornament, the two-dimensional code is not easy to identify, and popularization and application of the two-dimensional code are not facilitated.
The two-dimensional code of the metal ornament which can be realized at present has the following problems:
(1) The user cannot directly identify the two-dimensional code on the jewelry through the mobile phone. Only two-dimensional codes with extremely small sizes can be arranged on jewelry. The small-size two-dimensional code is directly printed on the metal base, and the two-dimensional code is difficult to directly identify due to serious reflection; the small-size two-dimensional code with the concave-convex structure is engraved on the ornament in a laser engraving mode, and precious metal loss is generated, so that the manufacturing cost of the precious metal ornament is increased.
(2) The jewelry product has small stored information quantity and lacks an effective digitalized interface. The method for directly engraving brand information or product parameters on jewelry or printing the brand information or the product parameters on a label of the jewelry in a bar code form is a common practice in jewelry industry, but the method has the defects of small information storage quantity, easy loss and the like; although the practice of applying the two-dimensional code to jewelry occurs, the two-dimensional code set on jewelry is limited to the situation that the two-dimensional code cannot be directly identified by a mobile phone of a user, and in fact, information associated with the jewelry is very little. The masses cannot conveniently and independently scan the two-dimensional codes on the surfaces of the jewelry, but can only scan the codes through equipment of merchants or manufacturers to finish commodity tracing or upload digital information, such as recalled pictures/videos/audios/characters and the like related to the jewelry. This in fact limits the application of the digitization function of jewelry considerably.
(3) The two-dimensional code can be invalid after long-term use of jewelry. Jewelry use faces long-term wear and contamination problems. The two-dimensional code directly printed on the metal base cannot resist abrasion, and the two-dimensional code is easy to fail after long-time use of the metal;
(4) The oversized mark influences the attractive appearance of jewelry. The larger the size of the two-dimensional code is, the easier the two-dimensional code is to be identified by external equipment, and the two-dimensional code arranged on jewelry needs to be very small so as not to influence the attractiveness of the jewelry.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a metal jewelry with a two-dimension code identification area and a preparation method thereof, wherein the two-dimension code which can be directly read by mass terminal equipment (such as a mobile phone) is arranged on the metal jewelry, so that the problem that a user independently scans the code to finish jewelry tracing and digital information editing is solved.
The technical problems to be solved by the invention are realized by adopting the following technical scheme:

S3: sticking an adhesive protective film on the surface of the metal jewelry, wherein the hollowed-out position is exactly aligned to the position of the metal jewelry, which needs to be marked with the two-dimensional code;
S4: electroplating a metal base surface of a two-dimensional code area exposed by a metal jewelry adhered with a self-adhesive protective film through a pen electric tool to form an electroplated layer only covering the two-dimensional code area, wherein the electroplated layer is a rectangular area with the side length of 1.5-4.5 mm, the color of the electroplated layer has to have obvious chromatic aberration relative to the metal base surface of the jewelry, and the contrast of the chromatic aberration value is more than 40%;
S5: after the electroplating of the electroplated layer of the two-dimensional code area of the metal jewelry is completed, tearing off the self-adhesive protective film adhered to the surface of the metal jewelry;
S6: and etching the electroplated layer by laser, and combining the area of the exposed jewelry metal base surface after the electroplated layer is etched with the area of the reserved electroplated layer to form a two-dimensional code identification area on the upper surface of the metal jewelry.
The electroplated layer of the two-dimensional code area is made of black rhodium material or black ruthenium material, the thickness of the electroplated layer is 1-3 um, and the black electroplated layer can form chromatic aberration meeting the two-dimensional code identification requirement relative to most common metal jewelry.
The self-adhesive protective film is a copper foil adhesive tape, a polyimide adhesive tape or a PPT adhesive tape with waterproof performance, wherein one end part of the self-adhesive protective film is provided with an adhesive-free part; and (3) cutting and forming by using a die or laser, wherein the length and width of the self-adhesive must be larger than those of the two-dimensional code area so as to ensure that the electroplating solution cannot pollute the area outside the two-dimensional code area when the electroplating operation of the step S4 is performed.
