Description

Coded anti-counterfeiting label with double matrixes and anti-counterfeiting method

Technical Field

The application belongs to the technical field of anti-counterfeiting, and particularly relates to an anti-counterfeiting label and an anti-counterfeiting method with double matrix codes by adopting metal fibers with high elastic deformation strength.

Background

With the development of economy and the progress of modern science and technology, the conventional anti-counterfeiting technology cannot meet the high-tech anti-counterfeiting requirement.

The traditional anti-counterfeiting means are fluorescent fibers, laser tags, inquiry type digital anti-counterfeiting tags, texture anti-counterfeiting tags, electronic radio frequency tag technology and the like.

Fluorescent fiber: the threshold is prevented from being extremely low, and the anti-counterfeiting effect is difficult to achieve.

Laser label: consumers also have no ability to recognize the authenticity of the label, the label is easy to forge, and 60% of counterfeits and 100% of genuine products are difficult to separate under the condition of lacking comparability; and secondly, the temperature change label is easy to identify by consumers but is easy to forge.

Query type digital anti-counterfeit label: consumers can inquire the authenticity of the digital label through telephone, short messages and the Internet, but the anti-counterfeiting digital label is printed on the surface of paper, so that the anti-counterfeiting digital label is easy to forge.

Texture anti-counterfeit label: the texture anti-counterfeiting technology uses the inherent speckle mark of the packaging material as an anti-counterfeiting identification mark. Consumers can inquire files and identify authenticity through Internet, fax and telephone. The random principle increases the forging difficulty. But the recognition difficulty of the public is high.

Electronic radio frequency label technology: by attaching RFID anti-counterfeiting labels to products, packages and the like, consumers can use RFID reading equipment to automatically scan for authentication, and after the RFID anti-counterfeiting label is combined with texture anti-counterfeiting and security line anti-counterfeiting, the consumers can really make sure and comfortable shopping. RFID is difficult to imitate, but requires specialized instrument identification.

In view of the foregoing, there is a continuing need in the anti-counterfeiting field to develop anti-counterfeiting technologies that are safer, more reliable, and easier to identify.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. It will be apparent that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without the need for inventive faculty, are within the scope of the present disclosure, based on the described embodiments of the present disclosure.

In the present application, each term has its meaning commonly understood in the art, unless specifically indicated otherwise or understood by context.

The term "tensile strength" in the present application refers to the ability of a material to resist permanent deformation and failure under the action of an external force, and in a tensile test, the maximum tensile stress to which a test specimen is subjected until breaking is the tensile strength at break. The greater the tensile strength in the elastic deformation region, the greater the ability of the material to resist bending deformation within the elastic limit, the tensile strength being determined according to GB/T228.1-2010 section 1 of the metallic Material tensile test: the measurement was carried out by the method described in room temperature test method.

As shown in fig. 3, the stress-strain curve of the metal material is divided into an elastic phase and a plastic phase. In the elastic phase, the stress is proportional to the strain of the specimen, the stress is removed, the deformation disappears, i.e. the specimen is in the elastic deformation phase, the yield point σy is the elastic limit of the material, which represents the maximum stress at which the material remains fully elastically deformed. After exceeding the yield point, the stress continues to be applied, and if the stress is relieved, the deformation of the test specimen can only be partially recovered, while a part of the residual deformation, i.e. plastic deformation, remains, which indicates that the deformation of the metal enters the elastoplastic deformation stage.

Fig. 4 is a stress-strain curve of amorphous fibers. As shown, the test results for CoFeSiB amorphous fibers of different diameters, sample 1, 100 microns in diameter and sample 2, 30 microns in diameter. Amorphous fibers are almost in the elastic deformation zone during the whole stretching process. The maximum tensile strength that can be sustained by the elastic deformation of the two amorphous fiber samples is higher than 600MPa. Amorphous fibers are the preferred material of the present invention.

In one aspect, the present application provides a label comprising a first substrate, a first coding region, wherein one or more straight first fibers with metallic luster, and a second coding region are provided, wherein one or more straight second fibers with metallic luster, and a second substrate are optionally provided, the first fibers and the second fibers are arranged in parallel, have a first end and a second end, and are connected with the first substrate, the second end is connected with the second substrate, the diameters of the first fibers and the second fibers are 1 to 300 micrometers, the maximum tensile strength that the first fibers can bear in an elastic deformation region is greater than or equal to 500MPa, and the maximum tensile strength that the second fibers can bear in the elastic deformation region is less than or equal to 490MPa. The inventors of the present application have unexpectedly found that when the maximum tensile strength that the fiber can withstand is greater when it is subjected to an elastic deformation zone, the fiber can recover almost completely after being temporarily bent without permanent bending. Conversely, when the maximum tensile strength that the fiber can withstand in the elastic deformation region is small, the fiber cannot be completely recovered after being temporarily bent, and permanent bending is likely to occur. In the technical scheme, two different fibers (namely, the first fiber and the second fiber) are simultaneously made, so that the effect of coding through different fiber reactions is achieved.

In some embodiments, the first fiber has a maximum tensile strength at the elastic deformation zone of 600MPa or more, 700MPa or more, 800MPa or more, 900MPa or more, 1000MPa or more, 1200MPa or more, 1500MPa or more, 2000MPa or more, 2500MPa or more,

And

The second fiber has a maximum tensile strength of less than or equal to 480MPa, less than or equal to 470MPa, less than or equal to 460MPa, less than or equal to 450MPa, less than or equal to 440MPa, less than or equal to 430MPa, less than or equal to 420MPa, less than or equal to 410MPa, less than or equal to 400MPa, less than or equal to 390MPa, less than or equal to 380MPa, less than or equal to 370MPa, less than or equal to 360MPa, less than or equal to 350MPa, less than or equal to 340MPa, less than or equal to 330MPa, less than or equal to 320MPa, less than or equal to 310MPa, less than or equal to 300MPa, less than or equal to 290MPa, less than or equal to 280MPa, less than or equal to 270MPa, less than or equal to 260MPa, less than or equal to 250MPa, less than or equal to 240MPa, less than or equal to 230MPa, less than or equal to 220MPa, less than or equal to 210MPa. The greater the maximum tensile strength parameter that the first fiber can withstand when it is in the elastic deformation zone, the more pronounced the fiber exhibits "ability to recover almost completely after being temporarily bent without permanent bending". In this case, the smaller the maximum tensile strength parameter that can be tolerated by the second fiber in the elastic deformation zone, the more pronounced the fiber exhibits "after being temporarily buckled, cannot recover completely, produces permanent buckling". Thus, the coding effect of the fiber is more obvious, and the specific coding is easier to judge.

In some embodiments, the length of the fibers between the first and second substrates is from 1 to 100mm, such as from 2 to 50mm, such as from 3 to 30mm, such as from 5 to 10mm. The length of the intermediate portion is not limited, but for the reasons of application of the present invention, it is appropriate to set the length as above.

The base material is not particularly limited, and materials commonly available to those skilled in the art can be used. In some embodiments, the matrix materials of the first and second matrices each independently comprise at least one of the following materials: plastic, paper, cloth, glass, wood, metal, etc.

In some embodiments, the first fibers are amorphous fibers. Amorphous fibers have defined specific properties and are particularly suitable for use in preparing the products of the present invention. The maximum tensile strength of the amorphous fiber in the elastic deformation zone can reach 600MPa or more, 700MPa or more, 800MPa or more, 900MPa or more, 1000MPa or more, 1200MPa or more, 1500MPa or more, 2000MPa or more and 2500MPa or more.

The term "amorphous fiber" in the present application has a meaning generally understood by those skilled in the art. In general, it refers to an alloy fiber containing various alloying elements such as Co, fe, mn, ni, si, B, C, transition metal elements, and the like. The method for producing the amorphous fiber is not particularly limited as long as the parameters thereof conform to the limitations. Generally, methods of making amorphous fibers include taylor, internal water spinning, and melt pulling. The amorphous fiber prepared by using the taylor spinning method has a diameter of 10-50 μm and has a glass coating layer. In the present application, the term "taylor spinning method" or "taylor method" is a term interchangeably used and refers to a method of spinning by:

1. Firstly, providing a master alloy rod with required components, and selecting a glass tube matched with the master alloy rod, wherein the difference between the melting point of the master alloy and the softening temperature of the glass tube is higher than 50 ℃ and lower than 500 ℃;

2. inserting a master alloy rod into the bottom of the glass tube;

3. Melting the bottom of the master alloy rod by adopting a high-frequency induction furnace;

4. softening the glass tube with the melted master alloy;

5. pulling out the wire in a drawing mode;

6. and cooling the master alloy in a molten state by a rapid solidification mode to form the amorphous alloy wire.

The method may further comprise the steps of:

7. Winding the wire on a wire winding roller, wherein the winding speed of the wire is kept constant, and the linear speed is 10-100 m/min;

8. the continuous preparation of the wire is realized by adjusting parameters such as feeding speed, temperature and the like and keeping the stability of the drawing process.

For specific information regarding taylor's method, reference may be made to patent No. ZL201520399245.6.

The melt pulling method is another important method for preparing amorphous fibers with a diameter of 10-50 microns without a glass coating. In the present application, the term "melt pulling method" refers to a method of preparing amorphous fibers by:

the amorphous bare fiber is prepared by adopting a melt pulling method, and specifically comprises the following steps:

1. first providing a master alloy rod having a desired composition;

2. melting the master alloy by using an induction heating or laser heating mode, so that a stable pool is formed at the upper end of the master alloy;

3. Feeding the master alloy upwards by a mechanical device, and simultaneously cooling the master alloy by utilizing the connection part of the guide device and the master alloy to prevent the parts except the top end of the master alloy from melting;

4. and cutting the melted master alloy by adopting a copper wheel pair with a conical edge and rotating at a high speed to obtain the amorphous bare fiber.

For information about a specific melt pulling method reference may be made to the patent of utility model zl2015199262. X.

The internal spinning method is a third method for preparing amorphous fiber, which has an amorphous fiber diameter of 80-200 μm and has no glass coating layer.

In the present application, the term "internal water spinning" refers to a method of spinning by the steps of:

1. first providing a master alloy rod having a desired composition;

2. adding cooling water into the high-speed rotating drum so that the cooling water synchronously rotates on the inner wall of the drum;

3. placing the master alloy into a nozzle, and melting the master alloy by using an induction heating mode;

4. and (3) filling high-pressure gas into the nozzle, and spraying the melted master alloy into water to quickly solidify to prepare the amorphous bare fiber.

For information about specific internal spinning processes, reference is made to the patent ZL 201520399257.9.

The choice of the second fiber is not particularly limited as long as the foregoing parameter requirements are met. In some embodiments, the second fiber is an iron wire or a steel wire.

In some embodiments, the diameters of the first and second fibers each independently fall within at least one of the following ranges: 1 to 10 microns, 5 to 20 microns, 10 to 30 microns, 10 to 50 microns, 20 to 80 microns, 30 to 100 microns, 50 to 300 microns. The diameter of the fiber can be different according to the preparation method and the actual requirement. The present application is not particularly limited with respect to the fiber diameter. The finer the fiber diameter, the more difficult it is to prepare. In addition, the appearance of the first and second fibers should be the same or similar, avoiding the distinction between the two that can be found by the naked eye.

In some embodiments, the tag is provided with a code, a first code is provided at a location corresponding to the first code region, and a second code is provided at a location corresponding to the second code region, for example code 1 is provided at a location corresponding to the first code region, and code 0 is provided at a location corresponding to the second code region, thus obtaining a series of codes consisting of "1" and "0". After the label is provided with the code, a common consumer can more easily recognize whether the code obtained by anti-counterfeiting detection is consistent with the given code, if so, the detection is a genuine product, and if not, the detection is an imitation product. Alternatively, a commodity provides a fixed code, and if a label different from the fixed code is used, the commodity is judged to be a counterfeit product by anti-counterfeit detection.

In another aspect, the application discloses an anti-counterfeiting method comprising:

Step 1, providing a commodity fixedly connected with an anti-counterfeiting label, wherein the structure and/or appearance of the anti-counterfeiting label is consistent with any label disclosed by the application;

Step 2, cutting the first fiber and the second fiber from between the first matrix and the second matrix to form fiber free ends;

Step 4, releasing the bent fiber free ends;

The anti-counterfeiting method is simple and easy to implement, the purpose of anti-counterfeiting detection can be achieved without special tools, and a commodity purchaser can also feel fun when performing anti-counterfeiting detection, so that the anti-counterfeiting method is a very good anti-counterfeiting detection method. It should be noted that the label and the commodity are not necessarily integrated, and even if the anti-counterfeit label is sold separately, such as a tag of clothes or an anti-counterfeit label of hairy crabs, the technical scheme disclosed by the invention is adopted, or the technical scheme adopted by the person skilled in the art without creative labor on the basis of the technical scheme disclosed by the invention falls into the protection scope of the invention.

In some embodiments, the bending angle obtained in step 3 is up to 150 degrees or more, preferably 170 degrees or more, preferably about 180 degrees. The bending angle is not particularly limited during detection, but in order to achieve a better detection effect, the larger the bending angle is, the more the performance of the label provided by the invention is different from other labels, so that the anti-counterfeiting effect of the anti-counterfeiting label can be displayed.

In some embodiments, the step of determining the authenticity of the tag further comprises comparing the read code with the code on the tag, thereby determining the authenticity of the tag.

The application also discloses an article to which the label according to any of the disclosed application is attached. The anti-counterfeiting label is connected with the commodity, and a purchaser of the commodity can easily distinguish authenticity by a simple detection method.

In some embodiments, the first and/or second substrates of the label are affixed to the article, thereby completing the attachment.

The label manufacturing method is very simple, and the bonding of the matrix and the fiber according to the requirement can be completed by adopting the adhesive.

The above-described ranges may be used alone or in combination. The application will be more readily understood by the following examples.
