Detailed Description
The technical solution of the present invention will be further described in more detail with reference to the following embodiments. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Anti-counterfeit labels are widely used for protecting commodities, and conventionally, label paper is usually used, and is made into labels by using special materials or setting special colors, and the labels are attached to the surfaces of the commodities to prevent counterfeiting. However, with the development of science and technology, the anti-counterfeit labels used in the past are easy to counterfeit even if special materials with special colors are used, and the anti-counterfeit effect of the anti-counterfeit labels is weaker and weaker.
Two-dimensional codes and bar codes represent binary data using a black and white rectangular pattern, and information contained therein can be acquired after being scanned by a device. The merchant may point to a particular meaning, such as a designated web page, or other identification code, with a two-dimensional code or binary data represented. The invention adds the explicit and invisible anti-counterfeiting function on the basis of the two-dimensional code and the bar code identification.
In the invention, the two-dimensional code or the bar code is prepared by using the anti-counterfeiting material prepared by the vacuum coating method, the two-dimensional code or the bar code is distinguished from the common ink technology, and the prepared material has special physical information, such as luster which can be identified by naked eyes or physical information which can be identified by instruments, so that the prepared two-dimensional code has anti-counterfeiting capability. The two-dimensional code or bar code anti-counterfeiting information prepared by the invention can be divided into two layers, wherein the first layer is used for anti-counterfeiting through the specific luster of metal or certain materials and the color change which can be identified by naked eyes; the second layer is the digital information for each point tested and processed by the instrument.
Referring to fig. 1, fig. 1 is a schematic flow chart of a manufacturing method of an anti-counterfeit label provided by the present invention. The method comprises the following steps:
s110: and generating the anti-counterfeiting label with the designated meaning information, and manufacturing a mask plate with the shape of the anti-counterfeiting label.
In the present invention, the two-dimensional code is taken as an example of the anti-counterfeit label. Two-dimensional code generators are already a very mature technology. Firstly, a two-dimensional code with designated meaning information is generated, and then a mask plate with a two-dimensional code shape is manufactured. The reticle is obtained by etching a mask pattern on a substrate, as shown in fig. 2. In this embodiment, the two-dimensional code is the mask pattern. Meanwhile, the anti-counterfeit label is not limited to the two-dimensional code, and can be a bar code, other patterns and other types of anti-counterfeit labels. And after the mask is generated, the hollow part of the mask is the shape of the two-dimensional code.
S120: and (3) under a vacuum environment, the atoms of the target material are gasified by adopting a sputtering or evaporation mode to act on the surface of the target material, and the gasified target material atoms pass through the mask plate to be deposited on the substrate to form the anti-counterfeiting label.
After the mask is manufactured, the step of manufacturing the anti-counterfeiting label (two-dimensional code) is started. In the present invention, a vacuum environment is prepared in advance for producing the two-dimensional code, and the two-dimensional code is usually in a vacuum chamber. A metal target, a mask and a substrate are provided. The metal target material is acted by sputtering or evaporation to gasify the atoms of the target material. When the atoms of the metal target material are gasified, the prepared mask plate is placed in the gasification direction, and the metal atoms pass through the through holes on the mask plate so as to be deposited on the substrate arranged behind the mask plate. The invention relates to a gasification coating mode which at least comprises pulsed laser deposition, magnetron sputtering, molecular beam epitaxy and electron beam evaporation. When magnetron sputtering is adopted, ions bombard the surface of the target material to gasify atoms on the surface of the target material, and the atoms are deposited on the substrate in different time. The embodiment of the present invention will be described as a pulsed laser deposition method. Laser deposition is the sputtering of target atoms caused by the irradiation of laser rays through a laser generator onto the surface of the target. Because the hollowed-out shape of the mask is the two-dimensional code shape, the deposited shape is also the two-dimensional code shape after the metal atoms are sputtered onto the substrate. And a two-dimensional code pattern is formed on the substrate by controlling the laser ray generator to irradiate the target for a specified time.
Further, the substrate used in the present invention is a rollable foil, preferably a metal foil such as aluminum foil, copper foil, or the like, or a plastic film. And after a two-dimension code is sputtered and formed, controlling the foil to roll, and aligning the mask to the position of the non-sputtered metal on the foil, thereby realizing the mass production of the two-dimension code.
Furthermore, a plurality of different metal target materials at different positions can be arranged, laser of the laser ray generator is controlled to irradiate different metal target materials in time-sharing sequence, when metal atoms pass through the mask plate and are deposited on the foil, the formed two-dimensional code is made of metal alloy, and alloy components and contents at different positions on the two-dimensional code are different, so that counterfeiting is prevented to a greater extent. Meanwhile, the heater is arranged on the back side of the foil for depositing the target metal, and deposited atoms can be promoted to be uniformly mixed due to the heating effect of the heater during metal atom deposition, so that the two-dimensional code is generated.
Meanwhile, the invention can also adopt the technical scheme of setting a plurality of masks. Taking two mask plates as an example, the hollow parts of the two mask plates are subsets of the two-dimensional code shape, and the two mask plates are combined to form a complete two-dimensional code shape. When two targets are arranged for sputtering, laser rays of a laser ray generator are controlled to irradiate target metal in turn in a time-sharing manner, and the mask plates are arranged in the sputtering direction of target atoms. The switching frequency of the target material is the same as or different from the switching frequency of the high-energy ray generator for time-sharing irradiation of the target material.
Taking the two masks and the two targets as an example, if pulsed laser deposition is utilized, the uniformity of the metal material sputtered to deposit in the space is poor, the alloy of the target metal can be obtained on the substrate, and the components and the contents of the metals in the alloys at different positions are different; if the mode of ion impact on the target is adopted, the uniformity of the metal obtained after sputtering deposition is good, three different metals can be formed by simultaneously switching the target and the mask at the same position, and the two-dimensional code formed on the foil contains three components of two target atomic alloys or two target metals. By controlling the sputtering time of the target and controlling the frequency of the switching mask, the appointed metal or alloy can be deposited at the appointed position of the foil, so that the content of the metal component of each material point of the prepared two-dimensional code is known.
Different from the conventional two-dimensional code, the two-dimensional code is formed by metal deposition, the metal components and content of each material point on the two-dimensional code are obtained by design, and the two-dimensional code prepared by the two-dimensional code manufacturing method cannot be obtained by imitation if the two-dimensional code is not manufactured by a preset scheme.
S130: and detecting and recording the material characteristic coefficient of each material point on the anti-counterfeiting label through a detector.
After the two-dimensional code is manufactured, the material characteristic coefficient of each material point or the designated material point on the two-dimensional code is monitored and recorded through a detector, wherein the material characteristic coefficient at least comprises a spectral coefficient, a light reflection coefficient and a magnetic performance coefficient of metal. And a detector is used for specifically obtaining specific numerical values of the characteristic coefficients of the materials.
S140: and adding the material characteristic coefficient to the designated meaning information to obtain new meaning information of the anti-counterfeiting label.
And after the specific numerical value of the material characteristic coefficient of all or the specified material points on the two-dimensional code is obtained, the specific numerical value is added into the specified meaning information when the two-dimensional code generator generates the two-dimensional code. At the moment, whether the product is a counterfeit product can be known by scanning the two-dimensional code. The metal material of the prepared two-dimensional code comprises metal, oxide, nitride and other materials which can be prepared by PVD technology, and in this case, the meaning information of the two-dimensional code not only comprises the meaning information set when the two-dimensional code is generated, but also comprises the material characteristic coefficients of the designated or all material points on the two-dimensional code. The distribution of metal materials of the forged two-dimensional code cannot be the same as that of the two-dimensional code manufactured by the method, and whether the forged two-dimensional code is a forged anti-counterfeit label or not can be determined by scanning.
In other embodiments of the invention, a metal or alloy solution is prepared, the solution is sprayed onto the foil through a mask plate in the shape of the anti-counterfeit label by a spraying mode, and a two-dimensional code can be formed on the foil after the metal solution is solidified by controlling the spraying speed. In another embodiment, the two-dimensional code may be generated by controlling the ejection speed and the ejection dose of the ejection head by a computer.

According to the invention, various information can be added on the basis of the conventional two-dimensional code, and the information complexity is improved, so that the counterfeiting difficulty is improved.
