Description

Technical Field

[0001] The present invention relates to the technical field of commodity labels, and in particular to a radio frequency label and a commodity whose authenticity can be detected at a glance. Background Art

[0002] There are many types of anti-counterfeiting packaging on the market that use "printing and packaging technology and packaging materials" as the threshold, and counterfeit brand products are often seen on the market. The manufacturer of anti-counterfeiting packaging does not bear the anti-counterfeiting responsibility because the "technical threshold and investment threshold of printing and packaging technology anti-counterfeiting" are not unique and are not enough to become a reliable anti-counterfeiting barrier.

[0003] Although traditional RFID tags provide a one-to-one anti-counterfeiting basis, they have many defects. The application of traditional RFID tags in commodity anti-counterfeiting is:

[0004] (1) The manufacturing process of traditional RFID tags is complicated. The chemical etching RFID antenna process produces a large amount of waste liquid and wastewater, and the manufacturing cost of RFID tags is high.

[0005] (2) The structure of traditional RFID tags does not have distinct features, and consumers cannot visually distinguish the authenticity of RFID tags.

[0006] (3) The traditional anti-counterfeiting operation mode of RFID tags is to read the data in the chip and compare it with the backend product database. After the backend database information is processed, the authenticity of the product can be issued. This is a troublesome matter for brand owners, sellers, and consumers, which affects the promotion and application of traditional RFID tags in the anti-counterfeiting industry.

[0007] In addition, in order to prevent the RFID tags from being peeled off for secondary use, some RFID tags are made of fragile paper, but fragile paper has the following defects:

[0008] (1) The high price of shredded paper increases the transaction costs of branded goods;

[0009] (2) The tensile strength of fragile paper labels is low and they are not suitable for high-speed labeling product packaging lines for medicines, alcohol, food, and bulk commodities;

[0010] (3) Fragile paper is easily available in the market, which results in a low technical threshold for counterfeiting anti-counterfeiting fragile paper RFID tags and poor anti-counterfeiting effect.

[0011] Therefore, there is an urgent need for a radio frequency tag that can enable people to visually identify the authenticity of goods during circulation. Summary of the invention

[0012] In order to overcome the deficiencies of the prior art, the present invention provides a radio frequency tag and a product whose authenticity can be detected at a glance.

[0013] The technical solution of the present invention is as follows:

[0014] A radio frequency tag whose authenticity can be seen at a glance, comprising a release base paper, a pressure-sensitive adhesive layer, a copper wire ultra-high frequency antenna, a double-circle radio frequency resonant cavity assembly and a label surface layer.

[0015] 1. Release paper and pressure-sensitive adhesive layer

[0016] The release paper is coated with a light release agent and is provided with a pressure-sensitive adhesive layer, which can meet the requirements of automatic labeling machines.

[0017] 2. Copper wire UHF antenna

[0018] The copper wire UHF antenna is formed by bending 0.06mm to 0.07mm copper wire and pasted on the surface of the pressure-sensitive adhesive layer. The shape of the copper wire UHF antenna can be straight, sinusoidal, square, triangular, trapezoidal, toothed, or mixed. If it is peeled off from the pressure-sensitive adhesive layer, the copper wire waveform will be destroyed, the antenna will fail, and the antenna will be prevented from being used again.

[0019] 3. Double-loop RF resonant cavity assembly

[0020] The double-circle RF resonant cavity assembly is located on the surface of the copper wire UHF antenna and coupled with it to form an ultra-high RF tag. The double-circle RF resonant cavity assembly includes a PET base film, a micro double-circle RF resonant cavity, and a RF chip.

[0021] (1) PET base film

[0022] The back surface of the PET base film is laser cut by a CO2 laser beam to form perforated slits.

[0023] (2) Micro dual-coil RF resonant cavity

[0024] The micro double-circle radio frequency resonant cavity is located on the PET base film, and the micro double-circle radio frequency resonant cavity is coupled with the radio frequency chip to form an ultra-high radio frequency tag. The micro double-circle radio frequency resonant cavity includes an inner circle aluminum foil and an outer circle aluminum foil formed by etching aluminum foil.

[0025] (3) RF chip

[0026] The package pins of the RF chip include two package balancing pins and two package pins, and the two package balancing pins are connected by a short-circuit. One package balancing pin is connected to one end of the inner circle aluminum foil, the other package balancing pin is connected to one end of the outer circle aluminum foil, one package pin is connected to the other end of the inner circle aluminum foil, and the other package pin is connected to the other end of the inner circle aluminum foil.

[0027] The TID (Traceability Identifier) ​​in the RF chip has a brand-customized code, which corresponds to the brand and cannot be rewritten. This makes the RF chip correspond to the brand and prevents counterfeiting.

[0028] 4. Label surface

[0029] The label surface layer is bonded to the release backing paper, and surrounds the copper wire UHF antenna and the double-circle RF resonant cavity assembly inside. The label surface layer is made of transparent material with a pattern printed on its surface. By corresponding the pattern with the double-circle RF resonant cavity assembly, the corresponding result can be viewed at a glance.

[0030] The pattern includes a resonant cavity assembly symbol that is consistent with the shape of a double-loop RF resonant cavity assembly, a chip symbol that is consistent with the shape of an RF chip, and an antenna symbol that is consistent with the shape of a copper wire UHF antenna. The pattern also includes a brand identification chip symbol, a brand logo pattern area printed with the brand's logo, and responsibility text, where the brand identification chip symbol is one-to-one with the brand code and brand, and the corresponding responsibility text is "assume anti-counterfeiting responsibility and compensate for the loss caused by imitation".

[0031] On the other hand, a commodity includes a commodity packaging, on which the above-mentioned radio frequency tag that can detect authenticity at a glance is provided.

[0032] The beneficial effect of the present invention according to the above scheme is that, through the transparent design of the label surface layer, the design of the label surface layer and the internal chip shape, the copper wire shape, the resonant cavity shape, the brand logo and the like, the consumers can confirm the authenticity of the goods at a glance when purchasing the goods, and the authenticity identification is more efficient and accurate; at the same time, through the radio frequency identification of the CBIC in the chip, radio frequency identification can also be performed in a variety of radio frequency readers and writers, which is conducive to authenticity identification in various circulation links, and is conducive to product traceability and authenticity identification in various links.

[0033] The copper wire and the radio frequency resonant cavity in the present invention are not allowed to be used twice, so that the investment cost of counterfeit labels is greater than the benefits of counterfeit goods, so that counterfeiters will give up when they see the difficulty.

[0046] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0047] like Figures 1a to 7 As shown, in order to overcome the defects of existing radio frequency tags that are easily reused or used for anti-counterfeiting, and the manufacturer of anti-counterfeiting packaging does not bear the anti-counterfeiting responsibility, the present invention provides a radio frequency tag that can be easily identified at a glance, which can be customized to form a product label that is uniquely corresponding to the brand. The radio frequency tag that can be easily identified at a glance includes a release backing paper, a pressure-sensitive adhesive layer, a copper wire ultra-high frequency antenna, a double-loop radio frequency resonant cavity assembly, and a label surface layer.

[0048] 1. Release paper and pressure-sensitive adhesive layer

[0049] The release paper 1 is coated with a light release agent, and a pressure-sensitive adhesive layer 2 is provided on the surface of the release paper 1. The release paper 1 is connected to the pressure-sensitive adhesive layer 2 through the release agent, which can meet the requirements of an automatic labeling machine.

[0050] 2. Copper wire UHF antenna

[0051] The copper wire UHF antenna 3 is formed by bending a copper wire and is pasted on the surface of the pressure-sensitive adhesive layer 2. The diameter of the copper wire is 0.05 mm to 0.08 mm (preferably 0.06 mm to 0.07 mm), and the resistance of each meter of the copper wire is less than 7.5 ohms, ensuring that the copper wire can be torn apart under gravity under normal use to avoid secondary use.

[0052] The shape of the copper wire UHF antenna 3 is a straight line, a sine wave, a square wave, a triangle wave, a trapezoid, a tooth shape, or a mixed wave. A mixed wave refers to a shape formed by connecting any two or more of the above-mentioned shapes, such as a straight line, a sine wave, a straight line, and the like.

[0053] 3. Double-loop RF resonant cavity assembly

[0054] like Figures 5 to 6b As shown, the double-loop RF resonant cavity assembly 4 is located on the surface of the copper wire UHF antenna 3 and coupled therewith to form an ultra-high frequency tag. The double-loop RF resonant cavity assembly 4 includes a PET base film 4-3, a micro double-loop RF resonant cavity 4-2, and a RF chip 4-1.

[0055] (1) PET base film

[0056] The plane size of the PET base film 4 - 3 is 8 mm×9 mm, and its thickness is 50 μm.

[0057] The back surface of the PET base film 4-3 is cut by a CO2 laser beam to form a laser slit 4-4, and the CO2 laser beam will not cut and damage the aluminum foil of the micro double-loop RF resonant cavity 4-2, and will not cut the copper wire UHF antenna 3, so it will not affect the performance of the RF tag. The laser slit 4-4 is a tooth hole groove (the laser slit connects the aluminum foil with a thickness of only 10 microns and a width of 0.2 mm), so that when the double-loop RF resonant cavity assembly 4 attached to the surface of the product is peeled off, the double-loop RF resonant cavity assembly 4 is broken along the laser slit to form two small pieces, which can prevent the RF tag from being used twice.

[0058] (2) Micro dual-coil RF resonant cavity

[0059] The micro double-circle RF resonant cavity 4-2 is located on the PET base film 4-3, and the micro double-circle RF resonant cavity 4-2 is coupled with the RF chip 4-1 to form an ultra-high RF tag. The micro double-circle RF resonant cavity 4-2 includes an inner circle aluminum foil and an outer circle aluminum foil formed by etching aluminum foil. The openings of the inner circle aluminum foil and the outer circle aluminum foil are located at one place so as to be connected with the RF chip 4-1. The outer circle aluminum foil on the side opposite to the installation position of the RF chip 4-1 is provided with an antenna coupling position so that it can be coupled with the copper wire ultra-high frequency antenna 3.

[0060] The inner diameter of the inner circle aluminum foil is 3 mm to 5 mm, which can be adjusted according to different brands of chips to form double-circle RF resonant cavity assemblies of different sizes.

[0061] (3) RF chip

[0062] like Figure 1a to Figure 1c , Figure 5As shown, the package pins of the RF chip 4-1 include two package balancing pins 4-1-2 and two package pins 4-1-1, and the two package balancing pins 4-1-2 are connected by a short-circuit. One package balancing pin 4-1-2 is connected to one end of the inner ring aluminum foil, the other package balancing pin 4-1-2 is connected to one end of the outer ring aluminum foil, one package pin 4-1-1 is connected to the other end of the inner ring aluminum foil, and the other package pin 4-1-1 is connected to the other end of the outer ring aluminum foil. The RF chip 4-1 is fixed to the end of the miniature double-ring RF resonant cavity 4-2 by conductive resin, and the inner ring aluminum foil and the outer ring aluminum foil are connected in series by the short-circuit between the package balancing pins 4-1-2. The two package pins 4-1-1 of the RF chip 4-1 and the inductor connected in series with the inner ring aluminum foil and the outer ring aluminum foil form a double-ring RF resonant cavity assembly.

[0063] like Figure 4 As shown, a TID (Traceability Identifier) ​​code area is provided in the RF chip 4-1. The TID code area has a brand code (brand identification chip (CBIC custom code)). The brand code corresponds to the brand and cannot be rewritten. The RF chip corresponds to the brand to prevent counterfeiting. In the present invention, the TID code area includes a chip manufacturer code area, a custom code area, a serial number area, and may also include other number areas, wherein the chip manufacturer code in the chip manufacturer code area and the custom code in the custom code area are combined to form a brand code, which is unique and corresponds to the brand and branded product one by one, and the chip manufacturer information can be traced through the number.

[0064] 4. Label surface

[0065] like Figures 1a to 4 As shown, the label surface layer 5 is bonded to the release backing paper and is used to surround the copper wire UHF antenna 3 and the double-loop RF resonant cavity assembly 4 inside.

[0066] The label surface layer 5 is made of transparent material, and a pattern is printed on its surface. The pattern corresponds to the double-circle RF resonant cavity assembly 4, and the corresponding result can be viewed at a glance. The bottom surface of the label surface layer 5 is coated with a heavy release agent, and the label surface layer 5 is connected to the pressure-sensitive adhesive layer 2 through the release agent.

[0067] The printed patterns include the resonant cavity assembly symbol, chip symbol, antenna symbol, brand identification chip symbol, brand LOGO pattern area, and responsibility text. Among them, the resonant cavity assembly symbol is consistent with the shape of the double-circle RF resonant cavity assembly, the chip symbol is consistent with the shape of the RF chip, the antenna symbol is consistent with the shape of the copper wire UHF antenna, the brand identification chip symbol corresponds to the brand code and brand one by one, the brand LOGO pattern area is printed with the brand LOGO, and the responsibility text is "assume anti-counterfeiting responsibility and compensate for the loss of imitation". The brand identification chip symbol, resonant cavity assembly symbol, chip symbol, and antenna symbol are all located in the left half of the label surface layer. Consumers can match this part of the content with the internal structure seen through the label surface layer to identify the authenticity at a glance; the brand LOGO pattern area and responsibility text are located in the right half of the label surface layer.

[0068] The width of the RFID tag that can detect the authenticity at a glance is 8 mm to 40 mm, and its length is 50 mm to 140 mm. Depending on the application scenario, there are different options for the size of the tag:

[0069] Anti-counterfeiting sealing labels for cartons, paper packaging, and plastic packaging: label width 10-12 mm, length 80-140 mm;

[0070] Daily cosmetics sealing label, wine bottle sealing label: label width 10 mm, length 80-100 mm;

[0071] Anti-counterfeiting labels for shoes, clothing, medicines and commodities: label width 30-40 mm, length 80-100 mm;

[0072] Anti-counterfeiting label for outer packaging of corrugated carton: label width 40 mm, length 100 mm;

[0073] Anti-counterfeiting labels for electronic product operation panels, display panels, and keypads: label width 40 mm, length 100 mm.

[0074] The present invention also provides a product, which includes a product package and a product body located inside the product package. The product package is provided with the above-mentioned RFID tag that can be used to directly identify the authenticity of the product package and the product body.

[0075] Naked eye recognition of the radio frequency tag of the present invention that can tell the authenticity at a glance:

[0076] 1. Personalized design symbols are printed on the surface of the label, including the brand logo chip symbol, the chip symbol with a short-circuit wire and the short-circuit wire is used to indicate the connection between the two package balance feet in the RF chip, the symbol for the resonant cavity assembly with two inner and outer circles of aluminum foil, the antenna symbol for the copper wire antenna, etc. These designs are original.

[0077] 2. The use of responsibility text represents the anti-counterfeiting manufacturer’s responsibility commitment.

[0078] 3. The application of transparent label surface allows consumers to see the structure inside the label surface from the outside.

[0079] On the one hand, the structure of the internal copper wire UHF antenna is different from the traditional antenna design, and its shape is consistent with the shape printed on the label surface; on the other hand, the internal double-circle RF resonant cavity assembly design can be seen from the outside, and its shape is consistent with the shape printed on the label surface.

[0080] Radio frequency identification of the radio frequency tag of the present invention that can detect the authenticity at a glance:

[0081] 1. Universal RFID reader to identify the authenticity of anti-counterfeiting RFID tags

[0082] The firmware of the universal reader is set with the "brand identification chip (CBIC custom code)" in the anti-counterfeiting label TID code, which is compared with the read RFID label TID code. If the CBIC custom code is present, it is confirmed to be a genuine anti-counterfeiting RFID label.

[0083] 2. Professional reader-writer identifies the authenticity of anti-counterfeiting radio frequency

[0084] Professional authenticity identification RFID readers group the brand identification chip CBIC custom code with the corresponding brand. Each brand chip custom code corresponds to a voice advertisement. When the CBIC custom code of the tag chip is read, the corresponding brand advertisement is immediately broadcast. Consumers can judge the authenticity of the product by hearing, which is a much better user experience than visually viewing the digital. For example:

[0085] (1) Consumers can identify the authenticity of goods before purchasing: Professional radio frequency readers are installed in shopping guide screens in shopping malls. When consumers approach the goods they want to purchase, if they hear the voice brand advertisement from the shopping guide screen and see the brand video introducing the goods, they can judge that the goods are authentic.

[0086] (2) When consumers pay and receive goods in a shopping mall, they can identify the authenticity of the goods: a professional RFID reader is installed on the cash register of the shopping mall to read the RFID tag of each item. If the item has a brand identification chip, the cash register printer will print the brand's logo or text or authentic symbol at the corresponding position of the product code on the receipt, providing consumers with traceable vouchers.

[0087] (3) Authenticity identification when the mall receives goods from manufacturers or middlemen: The mall installs a professional RFID reader at the incoming goods warehousing port to identify the RFID tags on the product packaging boxes. In addition to the warehousing information program, it also identifies the TID code of the RFID tag on the packaging box and the customized code of the brand identification chip. If the two are consistent, the brand's LOGO or code or identification symbol is printed in the corresponding column of the receiving goods warehousing form. If the customized code of the brand identification chip is not read, it is judged as a counterfeit brand product and an alarm photoelectric signal is issued to prompt relevant personnel to inquire.

[0088] (4) Consumers can identify the authenticity of goods: Tobacco, alcohol, and medicine stores, restaurants, hotels, bars, and other places provide consumers with micro brand identification and traceability cards for consumers to use to identify the authenticity of tobacco, alcohol, and medicine. Brand voice advertising before opening a bottle of famous wine allows guests to appreciate the real famous wine and the host to enjoy the joy of banqueting. At the same time, some expensive luxury goods (such as famous brand cigarettes, alcohol, medicines, handbags, watches, calligraphy and paintings, and arts and crafts) can be accompanied by a "brand identification and traceability card". When sharing luxury goods with others, the "brand identification and traceability card" reads the radio frequency tag of the luxury goods. The brand voice advertising enhances the image of the luxury goods and the holder.

[0089] The implementation principle of the radio frequency tag of the present invention, which can detect the authenticity at a glance, includes specially designed components and components that cannot be reused:

[0090] (1) The copper wire antenna and the coupled RFID tag cooperate with each other, the chip design with short-circuit wire, and the RFID resonant cavity structure with double-loop design, etc.

[0091] (2) The double-loop RF resonant cavity assembly and the copper wire UHF antenna cannot be reused: Among them, a laser cut is set on the back of the PET base film in the double-loop RF resonant cavity assembly, so that when the double-loop RF resonant cavity assembly is peeled off from the pressure-sensitive adhesive layer, the aluminum foil breaks and the resonant cavity function is lost; after the 0.06-0.08 mm thin copper wire is pasted on the pressure-sensitive adhesive layer, there is adhesion between the copper wire and the pressure-sensitive adhesive layer, which causes the copper wire to break or be pulled into a straight line during the pulling process, and the antenna function is lost.

[0092] In addition to the traditional RFID function, the RFID tag of the present invention that can detect authenticity at a glance also has the following features:

[0093] 1. The surface of the label is printed with special label symbols and anti-counterfeiting commitments, which can show performance different from traditional RFID tags.

[0094] 2. "Brand identification chip CBIC" is a chip specially customized by the brand. Different from the traditional radio frequency chip, it upgrades the anti-counterfeiting resources from the traditional printing and packaging process to the chip manufacturing process, and from the software code anti-counterfeiting to the chip hardware code anti-counterfeiting. The technology and capital invested in the anti-brand identification chip CBIC far exceeds the profits obtained by the counterfeiters, which makes the counterfeiters retreat.

[0095] 3. Among the tags, the copper wire antenna coupled RFID tag and the double-loop resonant cavity assembly with laser-cut grooves will become ineffective once folded, ensuring that they cannot be used a second time.

[0096] 4. The label is placed at the opening position of the product packaging, installed on the display screen, indicator light, and operation button switch. When the product is activated, the authenticity of the RFID tag must be peeled off, which will inevitably cause the label to separate and become invalid.

[0097] 5. It has a wide range of uses, involving the packaging of boxes, bottles, bags, and brands, and various electronic products.

[0098] The radio frequency tag of the present invention that can detect authenticity at a glance has the following social benefits:

[0099] 1. Radio frequency tags that can tell authenticity at a glance can simplify anti-counterfeiting identification, have extremely high anti-counterfeiting effects, and are widely used in a wide range of scenarios.

[0100] 2. Radio frequency tags that can tell authenticity at a glance can promote the anti-counterfeiting process from traditional printing and packaging technology to chip manufacturing technology. The extremely high chip technology and capital thresholds make it difficult for counterfeiters to start their business and cut off counterfeiting.

[0101] 3. RFID tags that can be identified at a glance help protect the brand.

[0102] 4. RFID tags that can be identified at a glance help create brands and protect new products and artworks from being counterfeited.

[0103] 5. The radio frequency tags that can tell the authenticity at a glance restrict counterfeiting and promote the reputation of Chinese manufacturing in the international market.

[0104] 6. The RFID tags that can be identified at a glance provide customized chips for government departments and industry associations to ensure that the commodities under their jurisdiction (medicines, medical supplies, fire-fighting supplies, building materials, auto parts, means of production, and civilian products) are not counterfeit or substandard, thereby improving the management efficiency of government departments and industry associations and improving social operation efficiency.

[0105] 7. The RFID tags that can be identified at a glance increase the resources for brand companies to expand and develop.

[0106] 8. Radio frequency tags that can identify authenticity at a glance promote the level of informatization in the manufacturing industry, allowing each product to have a chip and implement full-process tracking services from production and manufacturing to warehousing and logistics, sales and consumer applications.
