AI Technical Summary
The current gold-plated silver products cannot accurately identify the metal composition during the authentication process, and traditional anti-counterfeiting technologies are costly and easily counterfeited, leading to the easy occurrence of inferior products being passed off as superior ones during the recycling and return process.
Grooves are etched into the surface of a metal substrate and filled with metal to form a hidden anti-counterfeiting mark. The mark is revealed by a cleaning agent for authentication. Laser etching and electroplating techniques are used to hide the mark under the surface metal.
It enables low-cost and rapid product authenticity verification, reducing verification costs and improving verification accuracy.

TECHNICAL FIELD
[0001] The utility model relates to composite ornament technical field, concretely is a kind of hidden anti-fake mark for metal. BACKGROUND
[0002] Gold silver technology is a kind of surface decoration technology of metal product, mainly applied to the processing of gold and silver products.This technology involves covering a layer of gold and silver film or coating on the surface of metal object to improve the appearance and value of the object.Specifically, gold silver technology includes the following steps:
[0003] 1, surface treatment: first, surface treatment is carried out on the metal object to be processed to ensure its smoothness and cleanliness.
[0004] 2, gold and silver covering: through special process, such as hot pressing, electroplating, etc., gold and silver film is tightly attached to the surface of the object.
[0005] 3, polishing: finally, polishing and other treatments are carried out to make the gold and silver layer perfectly integrated with the surface of the object, showing a gorgeous effect.
[0006] The advantages of gold silver technology include:
[0007] 1, beautiful: gold and silver products have a golden luster on the surface, with high ornamental value.
[0008] 2, hard texture: since the inside is mainly silver, the overall texture is relatively hard and not easy to deform.
[0009] 3, moderate price: compared with pure gold products, gold and silver products are more affordable, while maintaining the characteristics of gold and silver.
[0010] However, due to the difference in metal composition, conventional identification methods (such as mass spectrometer) can identify the metal composition, but cannot accurately identify the content of each metal component without completely destroying the metal structure. Therefore, during the recycling and return of jewelry, it is easy to appear as good as bad, and to adjust the jewelry. Although there are anti-fake codes on the surface of the metal, this anti-fake technology needs to establish a traceability platform, which is high in cost and easy to imitate. Therefore, we propose a hidden anti-fake mark for metal to solve the problems mentioned above. UTILITY MODEL CONTENT
[0011] The utility model aims to provide a hidden anti-fake mark for metal to solve the problems mentioned in the background technology.
[0012] To achieve the above object, the utility model provides the following technical scheme: a kind of hidden anti-fake mark for metal, comprising: metal base layer, the metal base layer specified position is opened recess, recess is filled with covering metal, forms anti-fake mark, covering metal is flush with the surface of metal base layer, surface layer metal is covered on metal base layer and covering metal.
[0013] Preferably, the metal base layer is the bottom embryo of the composite ornament, which forms the shape of the ornament, and the metal base layer is a single texture metal.
[0014] Preferably, the surface of the metal base layer is etched with a laser etching technique to form recesses on the surface of the metal base layer.
[0015] Preferably, the recesses include but are not limited to numbers, patterns, two-dimensional codes and bar codes.
[0016] Preferably, the covering metal has the same material as the surface layer metal or other metal materials, and is electroplated on the recesses.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] By making recessed anti-fake marks on the surface of the metal base layer and electroplating and filling metal, the surface is smooth, and then a metal surface layer is covered to hide the anti-fake marks. When verifying, the metal at the anti-fake mark is removed by a cleaning agent to expose the anti-fake mark, which realizes verification and can quickly identify whether the corresponding product is an original product, thereby reducing the cost of verification. BRIEF DESCRIPTION OF DRAWINGS
[0019] Fig. 1 The figure is a structural schematic diagram of the utility model;
[0020] Fig. 2 The figure is a top view of the metal base layer in the utility model.
[0021] In the figure: 1, metal base layer; 11, recess; 2, covering metal; 4, surface layer metal. DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0023] Please refer to Figs. 1-2The utility model provides a technical scheme: a hidden anti -fake mark for metal, it is including: metal base layer 1, the recess 11 of metal base layer 1 specified position is set up, the recess 11 is filled with covering metal 2, forms anti -fake mark, covering metal 2 is flush with the surface of metal base layer 1, the surface layer metal 4 of covering metal 2 and metal base layer 1 is covered jointly,
[0024] When identifying, the surface layer metal 4 on the mark recess 11 is cleaned by the cleaning agent, the recess 11 filled with the covering metal 2 is exposed, and the identification function is realized.
[0025] Specifically, the metal base layer 1 is a bottom blank of a composite ornament, and the approximate shape of the ornament is constructed.
[0026] The surface of the metal base layer 1 is etched by a laser etching technology to form a unique recess 11, and the composite ornament is identified.
[0027] The material of the covering metal 2 can be the material of the surface layer metal 4 or other metal materials.
[0028] The surface layer metal 4 is a surface layer of the composite ornament, and the metal base layer 1 is wrapped by the surface layer metal 4 to meet the expectation of the value of the ornament.
[0029] Working principle: after the metal base layer 1 is shaped, it is placed on a laser to perform laser etching marking, and the marking is an arbitrary-shaped recess 11 formed on the surface of the metal base layer 1.
[0030] The metal is electroplated on the mark recess 11 by the electroplating technology to fill the mark recess 11 and make the surface of the metal base layer 1 flat.
[0031] Then, the metal base layer 1 with the mark is electroplated to make the surface layer metal 4 adhere to the metal base layer 1, the composite ornament is completed, the mark is completely hidden under the surface layer metal 4, and the consumer cannot easily perceive it.
[0032] When the authenticity of the product is suspected, the surface layer metal 4 on the mark layer is cleaned by the cleaning agent, and the mark is exposed to identify the authenticity of the product.
