Description

Technical Field

[0001] This utility model belongs to the field of barcode label technology, and in particular relates to a vulcanized barcode label for the position of the tire bead for anti-counterfeiting purposes. Background Technology

[0002] The sole traceability method for existing tires is the vulcanized barcode label. Traditionally, vulcanized barcode labels are produced primarily through carbon ribbon printing: one-dimensional, two-dimensional, or other code formats are printed onto blank vulcanized barcode labels using resin carbon ribbon. Once printed, the tire is ready for use. During use, the vulcanized barcode label is affixed to the tire carcass, which is then vulcanized in a vulcanizing cylinder. After vulcanization, the barcode is clearly readable, and the label becomes an integral part of the tire. This vulcanized barcode label serves as the sole traceability method for the tire, responsible for quality assurance and traceability after the tire enters the market.

[0003] However, as traditional vulcanized barcode labels became standard equipment on tires, their relatively simple production process led to their rapid widespread adoption and an increase in manufacturers. Consequently, some blank vulcanized barcode labels, previously only procured by tire factories, became readily available through various market channels. This has given rise to a new and problematic situation: unscrupulous individuals purchase blank vulcanized barcode labels through parallel import or counterfeit channels, print the desired graphics and text onto them using carbon ribbon, then manually remove the traditional vulcanized barcode labels from the tires and replace them with counterfeit ones. After being heat-vulcanized on the tires, these counterfeit labels appear almost identical to genuine ones, making them indistinguishable even to professionals. Consumers using tires with these counterfeit labels face unresolved after-sales issues, and the original manufacturers' reputations are severely damaged. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a vulcanized barcode label for the tire bead position that provides anti-counterfeiting features.

[0005] In view of this, the present invention provides a vulcanized barcode label for the bead position of an anti-counterfeiting tire, comprising the following sequentially connected components: A protective and pit-filling layer is used to embed and fill the photolithographic pits of the barcode carrier film; A barcode carrier film, wherein the barcode carrier film is formed with pits by ultraviolet lithography or carbon dioxide lithography, and the pits form at least one of letters, numbers and barcodes on the barcode carrier film. Vulcanized adhesive layer, used to react with tire rubber during tire vulcanization; The initial adhesive layer is used to temporarily fix a vulcanized barcode label at the tire bead position for anti-counterfeiting purposes before tire vulcanization. Anti-stick film is used to protect the tackiness of the initial adhesive layer.

[0006] Preferably, the protective and pit-filling layer is made of UV-curable resin adhesive or baking-type epoxy resin adhesive.

[0007] Preferably, the barcode carrier film is a high-temperature resistant polyester film with a thickness between 0.02 and 0.6 mm.

[0008] Preferably, the vulcanized adhesive layer is made of Chemlock adhesive or a similar heat-curing adhesive.

[0009] Preferably, the initial adhesive layer is made of modified rubber-based adhesive.

[0010] Preferably, the anti-sticking film is a silicone oil release film, and the thickness of the silicone oil release film is between 0.02 and 0.5 mm. Preferably, the pits on the barcode carrier film are generated by direct photolithography using an ultraviolet lithography machine to form pits with gray-black graphics on the surface of the barcode carrier film; Alternatively, a UV lithography machine can be used to first create pits with gray-black graphics, and then other graphics and barcodes can be printed in the pit area or other positions on the barcode carrier film using a carbon ribbon printing process. Alternatively, a gray-black image can be formed by photolithography using an ultraviolet lithography machine, and then a transparent image can be formed by photolithography on other areas of the barcode carrier film using a carbon dioxide lithography machine. Alternatively, first use ultraviolet lithography to form pits with gray-black graphics, then use carbon dioxide lithography to form pits with transparent graphics in other areas of the barcode carrier film, and finally use carbon ribbon printing to print other graphics and barcodes. Alternatively, a carbon dioxide lithography machine can be used to directly create recesses with transparent graphics, and then additional graphics and barcodes can be printed in the recessed areas or other designated locations on the barcode carrier film using a carbon ribbon printing process.

[0011] The beneficial effects of this utility model are: In this invention, the barcode carrier film is formed into pitted graphics by ultraviolet lithography or carbon dioxide lithography. The pit structure itself is difficult to replicate. At the same time, after the protective and pit filling layer is adapted to the pit, the lithographic graphics can present stable visual characteristics. The combination of the two creates a dual anti-counterfeiting barrier from both structural and visual levels, allowing consumers to quickly identify the authenticity of the label with the naked eye without the need for tools, effectively preventing counterfeiting. In addition, the protective and pit-filling layer can completely embed and fill the photolithographic pits, thoroughly sealing the gaps and preventing gas leakage at the label position at the tire bead, ensuring the long-term stability of the tire bead's airtightness; the vulcanized adhesive layer reacts chemically with the tire rubber during the vulcanization process, forming an irreversible and stable bond, preventing the label from falling off due to vibration and friction during tire use, ensuring the integrity of the label throughout its entire life cycle, and thus ensuring the continuous effectiveness of anti-counterfeiting and information identification functions.

[0018] like Figure 1 As shown, a vulcanized barcode label for the bead position of an anti-counterfeiting tire includes the following components connected in sequence: Protective and pit-filling layer 1, used to embed and fill the photolithographic pits of barcode carrier film 2; By embedding and filling the photolithographic pits in the barcode carrier film 2, on the one hand, the gaps formed by the pits can be sealed to prevent the air from leaking from the tire bead and ensure the stability of the tire bead's air tightness; on the other hand, the filled pits can work together with the protective layer to make the photolithographic images and text present clear, unique and stable visual features, laying a structural foundation for subsequent anti-counterfeiting identification. The barcode carrier film 2 is formed by ultraviolet lithography or carbon dioxide lithography, and the pits on the barcode carrier film 2 are formed by at least one of letters, numbers and barcodes. The barcode carrier film 2 is formed by photolithography using an ultraviolet lithography machine or a carbon dioxide lithography machine to create pits containing letters, numbers and barcodes. The pit structure gives the information physical anti-counterfeiting properties (non-planar printing is easy to counterfeit), and the photolithography process ensures that the information graphic content is highly accurate and does not fall off, meeting the anti-counterfeiting identification needs of the entire life cycle of the tire. Vulcanized adhesive layer 3 is used to react with tire rubber during tire vulcanization; During tire vulcanization, the label undergoes a cross-linking reaction with the rubber, enabling it to form a chemically bonded and stable adhesion to the tire bead. This prevents the label from falling off due to vibration and friction during tire use, ensuring the integrity and stability of the label throughout its entire lifespan. Initial adhesive layer 4 is used to temporarily fix a vulcanized barcode label for anti-counterfeiting at the tire bead position before tire vulcanization; Temporarily fixing the label before vulcanization allows for precise positioning of the label on the tire bead, preventing information loss due to label misalignment during vulcanization. At the same time, the temporary fixing method does not damage the tire rubber and enhances the subsequent vulcanization adhesion effect. Anti-sticking film 5 is used to protect the adhesiveness of the initial adhesive layer 4; It directly protects the adhesive surface of the initial adhesive layer 4, preventing dust and debris from adhering and causing adhesive failure during storage and transportation, ensuring stable initial adhesive performance when the label is used, and guaranteeing the reliability of the temporary fixing function.

[0019] As a preferred example of this application, the protective and pit filling layer 1 is made of UV-curable resin adhesive or baking-type epoxy resin adhesive. Among them, UV-curable resin adhesive has a fast curing speed and is easy to operate. The film formed after curing has high hardness and strong scratch resistance, which can effectively protect the information inside the pit. Baked epoxy resin adhesives exhibit excellent resistance to chemical corrosion and high and low temperatures after curing, making them suitable for harsh environments during tire use (such as oil, high and low temperatures). Both types of adhesives have good filling properties, which can be tightly embedded in the pits and fill them, ensuring that the information in the pits is not contaminated by external impurities, while improving the flatness of the label surface, making it easier for subsequent identification devices to read the information.

[0020] As a preferred example of this application, the barcode carrier film 2 is made of high-temperature resistant polyester film with a thickness of 0.125 mm; In this application, the barcode carrier film 2 is made of high-temperature resistant polyester film with a thickness of 0.125mm. On the one hand, its high-temperature resistance can withstand the high-temperature environment in the tire vulcanization process, avoiding deformation and melting of the film that could damage the graphics. On the other hand, the specific thickness range can balance the flexibility and stiffness of the film, making it easy for the label to fit the curved surface of the tire bezel, while ensuring that the pit depth is uniform and the graphics are clear during ultraviolet lithography or carbon dioxide lithography. At the same time, it avoids the carrier film being too thick, which would affect the overall fit of the tire bezel.

[0021] As a preferred example of this application, the vulcanized adhesive layer 3 is made of Chemlock rubber or a similar heat-curing adhesive. Such adhesives have high chemical reactivity with rubber under high-temperature vulcanization conditions, and can form high-strength chemical bonds, which greatly improves the bonding strength between the label and the tire rubber. After bonding, it has excellent aging resistance and high and low temperature resistance, and can withstand the vibration, friction and environmental erosion during tire use for a long time, thus preventing the label from falling off.

[0022] As a preferred example of this application, the initial adhesive layer 4 is made of modified rubber-based adhesive. The modified adhesive has the characteristics of low adhesion and high positioning: low adhesion ensures that the tire rubber surface is not damaged when peeling or adjusting the label position before vulcanization, thus avoiding affecting the subsequent vulcanization quality; high positioning can firmly lock the label position when temporarily fixed, preventing the label from shifting during handling and pre-vulcanization pretreatment, and ensuring that the graphic information is always in the preset recognition area.

[0023] As a preferred example of this application, the anti-adhesive film 5 is a silicone oil release film with a thickness of 0.05 mm. The silicone oil release film can achieve a medium-light peel force with the initial adhesive layer 4. It can be easily peeled off during use without leaving silicone oil on the adhesive layer surface, thus avoiding affecting the initial adhesion performance. The specific thickness range can ensure the tear resistance of the film and prevent the film from being damaged during storage and transportation, which would lead to the exposure and adhesion of the adhesive layer. At the same time, the thin design does not increase the overall thickness of the label, which is convenient for label rolling, cutting and other processing operations.

[0024] As a preferred example of this application, the method for generating the anti-counterfeiting graphic information with indentations on the barcode carrier film 2 is as follows: The barcode carrier film 2 is formed with gray-black graphics by direct photolithography using an ultraviolet lithography machine. This method features high contrast between gray and black images, making it easy to visually identify, and the physical structure of the photolithographic pits is difficult to imitate, resulting in outstanding basic anti-counterfeiting effects. Alternatively, a UV lithography machine can be used to first create a recess with gray-black graphics, and then a ribbon printing process can be used to print other graphics and barcodes in the recess area or other locations on the barcode carrier film 2. This method can add images / barcodes to the gray-black pits with carbon ribbon printing, which can increase the information carrying capacity (such as adding traceability codes, brand logos, etc.), and the carbon ribbon printing has rich colors, improving the information recognition. Alternatively, a recess with gray-black graphics can be formed by photolithography using an ultraviolet lithography machine, and then a recess with transparent graphics can be formed in other areas of the barcode carrier film 2 by photolithography using a carbon dioxide lithography machine. This method enables gray-black graphics and transparent graphics to form a visible-hidden anti-counterfeiting structure (transparent graphics require a specific angle or device for recognition), and the dual physical anti-counterfeiting measures increase the difficulty of counterfeiting. Alternatively, first use ultraviolet lithography to form pits with gray-black graphics, then use carbon dioxide lithography to form pits with transparent graphics in other areas of the barcode carrier film 2, and finally use carbon ribbon printing to print other graphics and barcodes. This method integrates visible graphics and text, invisible graphics and text, and multiple types of information, with the most anti-counterfeiting layers and the largest information capacity, which can meet the high anti-counterfeiting requirements of various scenarios. Alternatively, a carbon dioxide lithography machine can be used to directly form a recess with transparent graphics, and then other graphics and barcodes can be printed in the recess area or other designated positions on the barcode carrier film 2 using a carbon ribbon printing process. The transparent graphic recesses formed by this method have invisible anti-counterfeiting properties. Combined with the visible information printed by carbon ribbon, it simplifies the process (eliminating the need for UV lithography) while ensuring anti-counterfeiting effects, making it suitable for scenarios with different costs and anti-counterfeiting requirements.

[0025] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
