Description
Technical Field
The invention relates to the technical field of craft products, 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 through the method.
Background
The two-dimensional code has been widely applied to various fields of public life, and the common two-dimensional code displayed in the public is generally made in several forms of printing, display equipment display and laser direct engraving. When the two-dimensional code needs to be marked on the metal surface, the laser direct marking is the mainstream preparation method at present, and the definition of the two-dimensional code generated by the preparation method is not high. In order to be able to scan and identify, a two-dimensional code with a larger size needs to be manufactured, or a method is tried to improve the contrast of the two-dimensional code, but the prior art mainly improves the contrast in a two-dimensional code area, 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 make the bigger size two-dimensional code, then the metal surface occupies great area, and the contrast of two-dimensional code is not high, be difficult for scanning discernment or need to read through specific equipment scanning discernment, this kind of two-dimensional code that adopts laser direct marking, can only use in industrial use, need specific equipment scanning discernment, the information that civil mobile phone camera equipment can't accomplish scanning discernment reading two-dimensional code, directly mark the two-dimensional code with laser, still can produce obvious loss to the metal material, especially noble metal material, with the noble metal loss that laser direct carving produced will increase the manufacturing cost of noble metal ornaments, and be difficult for discernment, be unfavorable for popularization and application of two-dimensional code.
The metal ornament two-dimensional code that can realize at present has following several problems:
(1) the user can not directly identify the two-dimension code on the jewelry through the mobile phone. Two-dimensional codes with extremely small sizes can only be arranged on the 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 light reflection; the small-size two-dimensional code with the concave-convex structure is carved on the ornament in a laser carving mode, and the produced noble metal is consumed, so that the manufacturing cost of the noble metal ornament is increased.
(2) The jewelry product has less stored information amount and lacks an effective digital interface. The brand information or product parameters are directly engraved on the jewelry or printed on the label of the jewelry in a bar code form, which is a common practice in the jewelry industry, but the method has the defects of small information storage amount, easy loss and the like; although the practice of applying the two-dimensional code to the jewelry appears, the two-dimensional code set on the jewelry is limited to the situation that the two-dimensional code cannot be directly identified by a mobile phone of a user, and information related to the jewelry is very little in reality. The public cannot conveniently and independently scan the two-dimensional code on the surface of the jewelry, but can only scan the code through equipment of a merchant or a manufacturer to finish the tracing of the commodity or upload digital information, such as a recalled photo/video/audio/character and the like related to the jewelry. This effectively greatly limits the application of the digitizing function of the jewelry.
(3) The two-dimension code can be invalid due to long-term use of the jewelry. Jewelry is subject to 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 lose effectiveness after long-time use of the metal;
(4) the appearance of the jewelry is greatly influenced by the over-marking. The larger the size of the set two-dimensional code is, the more easily the two-dimensional code is identified by external equipment, and the two-dimensional code set on the jewelry needs to be very small so as not to influence the beauty of the jewelry.
