Description

Technical Field

[0001] This invention belongs to the field of tire traceability and identification technology, and particularly relates to tire number labels with anti-wear sidewall anti-spill rubber and semi-hollow characters integrated with tire numbers and their usage methods. Background Technology

[0002] As a core component of transportation, tires require comprehensive lifecycle traceability management for product quality control, logistics, after-sales traceability, and waste tire recycling. The tire number marking on the tire sidewall is the core carrier for achieving this traceability management. Currently, the industry commonly uses a fully hollowed-out barcode tire number structure for tire sidewall traceability. This tire number uses a white polyester plastic sheet as the base material, with one side coated with vulcanizing adhesive for bonding to the tire, and the other side printed with a barcode. A CO2 engraving machine is then used to engrave fully hollowed-out letters and numbers next to the barcode. During the tire vulcanization process, this fully hollowed-out tire number is affixed to the tire sidewall. Utilizing the high-pressure environment and the fluidity of the rubber compound within the vulcanization mold, the tire rubber fills the hollowed-out character and number areas, forming an integrated raised and recessed imprint on the tire. Simultaneously, scanning the printed barcode enables logistics line control, achieving basic tire traceability.

[0003] However, the existing fully hollow tire size design has two major unavoidable technical defects in actual production and use, which seriously restrict the efficiency and accuracy of tire traceability and have become a long-standing technical problem that needs to be solved in the industry: 1. Frequent rubber overflow and poor label recognition: The fully hollowed-out character and number areas have no obstructing structure. Under the high-pressure environment of tire vulcanization, the highly fluid tire rubber will overflow from the hollowed-out areas and form rubber bonds on the surface of the tire number label, causing the strokes of letters and numbers to become blurred and mixed. For characters with similar outlines, such as 6 and 8, it is very easy to make mistakes in identification. In the vulcanization process of some special-sized tires, the overflowed rubber will also directly cover the barcode area printed on the label surface, making it impossible for the barcode scanning equipment on the logistics line to recognize it, directly causing logistics to be hindered and reducing production efficiency.

[0004] 2. Barcodes are easily worn out, making full lifecycle traceability impossible: Tire numbers are generated by printing directly onto the label surface. However, the tire sidewall is completely exposed during use, constantly subjected to friction and impact from road sand and other objects. Furthermore, the tire undergoes multiple high-pressure washes during maintenance, which easily causes the printed barcodes to wear out and fall off. As a result, when the tire is recycled or managed after use, intelligent barcode scanning equipment cannot recognize the barcode information. The tire numbers must be manually copied one by one, which not only consumes a lot of manpower but also results in a very high rate of human error. It is impossible to achieve intelligent traceability of the entire lifecycle of the tire from production to recycling.

[0005] Meanwhile, some existing technologies for tire traceability barcode identification exist, such as a non-intaglio type anti-counterfeiting and anti-tampering tire bead barcode disclosed in patent CN202510088180.1. However, it is only applicable to the tire bead position, which is completely covered after the rim is assembled, making it impossible to achieve online traceability after the tire is assembled and used. Moreover, after the barcode label is forcibly peeled off, no permanent embossed marks formed by rubber are left on the tire body, posing a risk of label replacement or tampering, and failing to meet the anti-counterfeiting and information retention requirements of tire traceability.

[0006] In summary, for tire sidewall traceability scenarios, there is an urgent need for a tire number structure that can completely solve the problems of rubber spillage and wear of markings, while also being anti-counterfeiting and capable of online identification, so as to achieve efficient, accurate, and intelligent traceability management throughout the entire tire life cycle. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned technical problems by providing an integrated tire number label with anti-wear sidewall adhesive and semi-hollow characters, as well as its usage method.

[0008] This invention provides an integrated tire number label with anti-wear sidewall adhesive and semi-perforated characters, comprising the following components connected in sequence: The barcode character information carrier layer includes an integrated structure consisting of a transparent layer and a colored layer, wherein the transparent layer is the surface layer and the colored layer is the bottom layer; A vulcanized adhesive layer is disposed on the side of the colored layer opposite to the transparent layer, and is used to react with the tire sidewall rubber during tire vulcanization, so that the tire number and the tire sidewall are integrated. A release film is disposed on the side of the vulcanized adhesive layer opposite to the colored layer to protect the adhesive properties of the vulcanized adhesive layer; The integrated tire number has a semi-hollowed-out font structure, which penetrates the colored layer of the release film, the vulcanized adhesive layer and the barcode character information carrier layer, and terminates at the transparent layer without penetrating the transparent layer.

[0009] Furthermore, the transparent layer of the barcode character information carrier layer is a modified high-temperature resistant polyester transparent film with a thickness of 0.02-3mm; the colored layer is a modified high-temperature resistant white polyester film with a thickness of 0.012-3mm, and an anti-fouling layer is provided on the side of the transparent layer away from the colored layer.

[0010] Furthermore, the vulcanized adhesive layer is a Chemlock rubber-plastic hot vulcanizing adhesive.

[0011] Furthermore, the release film is a PET silicone oil film with a thickness of 0.01-3mm, used to protect the vulcanization adhesion of the vulcanized adhesive layer.

[0012] Furthermore, the semi-hollowed-out font structure is formed by etching from the side of the release film away from the vulcanized adhesive layer using an etching laser machine.

[0013] Furthermore, a photolithography information layer is provided between the transparent layer and the colored layer of the barcode character information carrier layer. The photolithography information layer is formed by photolithography using an ultraviolet lithography machine. The ultraviolet light of the ultraviolet lithography machine passes through the transparent layer and forms at least one information structure among barcodes, anti-counterfeiting characters, and brand logo characters on the surface of the colored layer.

[0014] Furthermore, the etched area of ​​the semi-hollowed-out font structure corresponds to the non-photolithographic information area on the front side of the barcode character information carrier layer.

[0015] Furthermore, it also includes a primary adhesive layer, which is disposed between the vulcanized adhesive layer and the release film.

[0016] Furthermore, the initial adhesive layer is made of modified rubber-based adhesive.

[0017] This invention also proposes a method for using a tire label with integrated anti-wear sidewall adhesive and semi-perforated characters, comprising the following steps: Peel the integrated tire number from the release film to expose the vulcanized adhesive layer; The integrated tire number with the vulcanized adhesive layer is attached to the preset position on the sidewall of the tire blank, or the integrated tire number is directly placed into the corresponding forming position on the sidewall of the tire vulcanization mold. The tire blank equipped with the integrated tire number is vulcanized. During the vulcanization process, the tire rubber material flows into the semi-hollowed-out font structure of the integrated tire number under the high pressure of the mold and completes the filling. At the same time, the vulcanized adhesive layer reacts with the tire sidewall rubber to fix the integrated tire number and the tire sidewall together. After vulcanization, the outline of the barcode / character formed by the tire rubber filling the semi-hollow font structure is clearly displayed through the transparent layer, and the barcode / character can be directly identified and traced by intelligent barcode scanning equipment.

[0018] The beneficial effects of this invention are: This invention achieves a firm bond between the tire number and the tire sidewall by using a layered design of a carrier layer structure with a transparent top layer and a colored bottom layer, plus a vulcanized adhesive layer and a release film. After vulcanization, the tire number becomes integrated with the tire, preventing it from falling off during use. The semi-perforated font structure only penetrates the release film, vulcanized adhesive layer and colored layer, and terminates at the transparent layer without penetrating it. Structurally, it completely eliminates the problem of rubber material overflowing from the perforation to the label surface during tire vulcanization, avoids blurry or mixed character strokes and rubber material covering the barcode, and ensures that the character and barcode outlines are always clear. The non-through design of the semi-hollow font structure, combined with the surface setting of the transparent layer, provides a stable visual carrier for the recognition of subsequent photolithography information or resin filling, while the transparent layer can form a basic protection for the internal structure.

[0025] This invention discloses an integrated tire number label with anti-overflow rubber and anti-wear properties, and a semi-hollowed-out characters, as well as its usage method. It relates to the field of tire traceability identification technology and aims to solve the technical problems of rubber overflow and barcode wear in traditional tires with fully hollowed-out tire numbers on the sidewall. It achieves efficient and accurate traceability throughout the entire life cycle of the tire. The technical solution of this invention is described in detail below with reference to specific embodiments. It should be noted that the scope of protection of this invention is not limited to the specific embodiments described below. All equivalent transformations made based on the concept of this invention fall within the scope of protection of this invention.

[0026] like Figures 1-3 As shown, the tire sidewall anti-spill rubber anti-wear and semi-hollowed-out character integrated tire number label includes the following sequentially connected components: The barcode character information carrier layer 1 includes an integrated structure consisting of a transparent layer 11 and a colored layer 12, wherein the transparent layer 11 is the surface layer and the colored layer 12 is the bottom layer; the transparent layer 11 and the colored layer 12 are integrated by curing with epoxy resin or by curing with UV glue under ultraviolet light.

[0027] The vulcanized adhesive layer 2 is disposed on the side of the colored layer 12 opposite to the transparent layer 11, and is used to react with the tire sidewall rubber during tire vulcanization, so that the tire number and the tire sidewall are integrated. Release film 3 is disposed on the side of the vulcanized adhesive layer 2 away from the colored layer 12, and is used to protect the adhesiveness of the vulcanized adhesive layer 2; The integrated tire number has a semi-hollowed-out font structure 13. The semi-hollowed-out font structure 13 penetrates the release film 3, the vulcanized adhesive layer 2 and the colored layer 12 of the barcode character information carrier layer 1, and terminates at the transparent layer 11 without penetrating the transparent layer 11. It should be noted that the semi-hollowed-out font structure 13 forms a ribbed hollowed-out font on the colored layer 12.

[0028] This invention achieves a strong bond between the tire number and the tire sidewall by using a layered design with a transparent layer 11 as the surface and a colored layer 12 as the bottom layer, plus a vulcanized adhesive layer 2 and a release film 3. After vulcanization, the tire number becomes integrated with the tire, preventing it from falling off during use. The semi-perforated font structure 13 only penetrates the release film 3, the vulcanized adhesive layer 2, and the colored layer 12, terminating at the transparent layer 11 without penetrating through. This structurally eliminates the problem of rubber overflowing from the perforated area onto the label surface during tire vulcanization, preventing blurred or mixed character strokes and rubber covering the barcode, ensuring that the character and barcode outlines remain clear. The non-penetrating design of the semi-perforated font structure 13, combined with the surface setting of the transparent layer 11, provides a stable visual carrier for subsequent photolithography information or identification after rubber filling. At the same time, the transparent layer 11 provides basic protection for the internal structure.

[0029] In the example of this application, the transparent layer 11 of the barcode character information carrier layer 1 is a modified high-temperature resistant polyester transparent film with a thickness of 0.02-3mm; the colored layer 12 is a modified high-temperature resistant white polyester film with a thickness of 0.012-3mm; an anti-fouling layer 5 is provided on the side of the transparent layer 11 away from the colored layer 12; the anti-fouling layer 5 is formed on the surface of the transparent layer 11 by coating with silicone oil or fluorine using a coating machine.

[0030] The transparent layer 11 uses a 0.02-3mm modified high-temperature resistant polyester transparent film, which combines high temperature resistance and high light transmittance, making it suitable for the high-temperature process of tire vulcanization. It also ensures that characters / barcodes and internal photolithography information after rubber filling are clearly identifiable through the transparent layer 11. Furthermore, this material has excellent wear resistance and washability, protecting the internal structure from external friction damage. As a preferred example of the invention, the colored layer 12 uses a 0.012-3mm modified high-temperature resistant white polyester film, creating a sharp visual contrast with the transparent layer 11 and improving the clarity of barcode and character recognition. Its high-temperature resistance is also suitable for the vulcanization process, preventing deformation and failure of the substrate layer at high temperatures. The thickness ranges of the transparent layer 11 and the colored layer 12 are designed to balance structural strength and thinness, preventing excessive thickness from affecting the overall fit of the tire sidewall, while ensuring the implementation of semi-perforated etching and ultraviolet lithography processes. Anti-fouling layer 5... It can significantly reduce the surface energy of the label, giving the label surface hydrophobic, oleophobic, and anti-adhesion properties. It can effectively block the adhesion of pollutants such as oil, dust, and rubber debris during tire production and use, and prevent the barcode and characters from becoming blurry or ineffective due to contamination. At the same time, the anti-fouling layer 5 can improve the scratch resistance and wear resistance of the label surface, slow down the surface aging under ultraviolet rays and high temperature environments, extend the service life of the label, and ensure that the barcode and character information are clear and readable for a long time.

[0031] In the example of this application, the vulcanized adhesive layer 2 is a Chemlock rubber-plastic hot vulcanizing adhesive.

[0032] As a preferred example of the present invention, the Chemlock rubber-plastic hot vulcanizing adhesive has excellent vulcanization reaction compatibility with the tire sidewall rubber and the colored layer 12 substrate of the tire number. During the tire vulcanization process, it can undergo a deep cross-linking reaction with the rubber, so that the tire number is permanently integrated with the tire sidewall and cannot be separated, thus completely preventing the tire number from falling off during tire use and ensuring the long-term effectiveness of the tire number.

[0033] In the example of this application, the release film 3 is a PET silicone oil film with a thickness of 0.01-3 mm, used to protect the adhesiveness of the vulcanized adhesive layer 2.

[0034] As a preferred example of the present invention, the release film 3 is made of 0.01-3mm PET silicone oil film. The silicone oil release layer can effectively protect the vulcanization adhesion of the vulcanized adhesive layer 2, and prevent the adhesive layer from being contaminated or sticking during storage and transportation of the tire number, thus ensuring the vulcanization adhesion effect of the adhesive layer during use. The PET substrate has good mechanical strength and high temperature resistance, which is suitable for the high temperature laser etching requirements of the semi-perforated etching process. There is no deformation during etching, ensuring the edge clarity of the semi-perforated font structure 13. The thickness range of the release film 3 matches the overall layer structure of the tire number, making it easy to peel off without damaging the vulcanized adhesive layer 2, which is convenient for the actual operation and use of tire factory operators.

[0035] In the example of this application, the semi-perforated font structure 13 is formed by etching from the side of the release film 3 away from the vulcanized adhesive layer 2 using an etching laser machine.

[0036] As a preferred example of the present invention, the etching laser machine is preferably a 20-300 watt carbon dioxide laser machine. The etching laser machine is used to etch a semi-hollowed-out font structure 13 from the side of the release film 3 away from the vulcanized adhesive layer 2. The etching direction is adapted to the layered structure of the tire number, so as to achieve precise layer-by-layer etching through the release film 3 → vulcanized adhesive layer 2 → colored layer 12. The laser depth can be precisely controlled to ensure that it terminates at the transparent layer 11 without penetrating, thus ensuring the forming accuracy of the semi-hollowed-out font structure 13. Compared with the traditional engraving process, the laser etching process has a faster forming speed, more accurate contours, no mechanical contact damage, and can ensure that the fine strokes of the barcode and characters are clearly formed, avoiding the errors of manual engraving and improving the production efficiency and consistency of the tire number.

[0037] In the example of this application, a photolithography information layer 14 is provided between the transparent layer 11 and the colored layer 12 of the barcode character information carrier layer 1. The photolithography information layer 14 is formed by photolithography using an ultraviolet lithography machine. The ultraviolet light of the ultraviolet lithography machine passes through the transparent layer 11 and forms at least one information structure among barcodes, anti-counterfeiting characters, and brand logo characters on the surface of the colored layer 12.

[0038] As a preferred example of the present invention, a photolithographic information layer 14 formed by ultraviolet lithography is disposed between the transparent layer 11 and the colored layer 12. Ultraviolet light passes through the transparent layer 11 and accurately forms information such as barcodes, anti-counterfeiting characters, and brand logos on the surface of the colored layer 12, so that the information is embedded under the transparent layer 11. Utilizing the wear-resistant and wash-resistant properties of the transparent layer 11, permanent protection of the information is achieved, avoiding information wear caused by friction and washing during tire use, and ensuring that both new tires and recycled tires can be identified by intelligent barcode scanning devices. The photolithographic information layer 14 is directly formed on the surface of the colored layer 12 and is integrated with the colored layer 12 without protrusions or delamination, preventing the information layer from falling off. At the same time, the high information resolution of the photolithography process improves the accuracy and efficiency of barcode scanning and identification. It can flexibly form various information structures such as barcodes, anti-counterfeiting characters, and brand logos according to needs, combining traceability and brand anti-counterfeiting functions, and improving the traceability and anti-counterfeiting level of tire products.

[0039] In the example of this application, the etched area of ​​the semi-perforated font structure 13 corresponds to the non-photolithographic information area on the front side of the barcode character information carrier layer 1.

[0040] As a preferred example of the present invention, the etched area of ​​the semi-perforated font structure 13 is corresponding to the non-photolithographic information area on the front side of the barcode character information carrier layer 1, thereby achieving regional separation between the photolithographic information layer 14 and the semi-perforated font structure 13. On the one hand, this avoids damage to the photolithographic information layer 14 caused by the etching process, ensuring the integrity and clarity of the photolithographic information; on the other hand, the rubber filling area of ​​the semi-perforated font structure 13 and the photolithographic information area do not interfere with each other, and the two information structures can be independently identified and mutually verified, further improving the accuracy and anti-counterfeiting of tire traceability; at the same time, this design makes the structural layout of the tire number more reasonable and makes full use of the effective area of ​​the carrier layer.

[0041] In the example of this application, a primary adhesive layer 4 is also included, which is disposed between the vulcanized adhesive layer 2 and the release film 3.

[0042] As a preferred example of the present invention, a primary adhesive layer 4 is added between the vulcanized adhesive layer 2 and the release film 3 to achieve a "double bonding" design for the tire size: First, before tire vulcanization, the primary adhesive layer 4 can increase the immediate initial adhesion force, temporarily and firmly fixing the tire size to the preset position of the tire blank, avoiding tire size displacement or detachment due to tire blank transfer, mold closing and other operations before vulcanization, and ensuring the accurate positioning of the tire size on the tire sidewall; Second, during the vulcanization process, the vulcanized adhesive layer 2 plays a permanent bonding role, and the primary adhesive layer 4 and the vulcanized adhesive layer 2 work together to further improve the bonding strength between the tire size and the tire, while the setting of the primary adhesive layer 4 does not affect the vulcanization reaction between the vulcanized adhesive layer 2 and the tire rubber.

[0043] In the example of this application, the initial adhesive layer 4 is a modified rubber-based adhesive.

[0044] As a preferred example of the present invention, the initial adhesive layer 4 is made of modified rubber-based adhesive. On the one hand, it has good material compatibility with the vulcanized adhesive layer 2, the release film 3 and the tire carcass rubber, and has moderate initial tack. It can achieve temporary and firm fixation of the tire size, and leave no residue when the release film 3 is removed, thus not contaminating the vulcanized adhesive layer 2. On the other hand, the modified rubber-based adhesive has good high temperature resistance, which is suitable for the high temperature process of tire vulcanization. At the same time, the adhesive has good aging resistance, which ensures that the initial tack effect of the tire size is stable during the storage period.

[0045] Based on the above-mentioned structural design of the tire label with anti-wear rubber on the sidewall and semi-hollowed-out characters, this invention provides three differentiated implementation methods to adapt to different tire production needs, cost budgets, and functional requirements. Implementation method C is designed for economy tires, achieving an optimal balance between cost and efficiency. The three implementation methods are described in detail below: Implementation Method A

[0046] 1. An integrated carrier layer with a transparent layer 11 and a colored layer 12 is prepared. A vulcanized adhesive layer 2, a primary adhesive layer 4 and a release film 3 are sequentially laminated on the side of the colored layer 12 away from the transparent layer 11 to form a tire number substrate. 2. Using an ultraviolet lithography machine, a barcode (or other code system) and characters are lithographically formed on the front side (one side of the transparent layer 11) of the tire number substrate: After the ultraviolet light passes through the transparent layer 11, barcode character information is formed on the colored layer 12. This barcode is used for tire logistics line operation and subsequent scanning. Since the barcode is placed under the label transparent layer 11, it can effectively resist wear. 3. Using a 20-300 watt CO2 laser machine, perform semi-hollow etching on the back of the tire number substrate (on the side of release film 3). During etching, use the laser beam of the laser machine to etch layer by layer on the front side, excluding barcode and character positions, sequentially etching through release film 3, initial adhesive layer 4, vulcanized adhesive layer 2, and colored layer 12, without etching through transparent layer 11.

[0047] Tire factory application scenarios: 1. Remove the tire number from release film 3 and stick it on the tire blank or place it in the corresponding position in the mold; 2. During vulcanization, the tire rubber compound flows into the semi-hollowed-out characters under the high pressure of the mold, forming a complete filling; 3. After vulcanization, the characters are filled in the black or colored rubber of the tire and perfectly displayed through the transparent layer 11 along with the barcode and characters formed by photolithography, which can be directly identified by intelligent scanning equipment. Implementation Method B

[0048] 1. An integrated carrier layer with a transparent layer 11 and a colored layer 12 is prepared. A vulcanized adhesive layer 2, a primary adhesive layer 4 and a release film 3 are sequentially laminated on the side of the colored layer 12 away from the transparent layer 11 to form a tire number substrate. 2. Using an ultraviolet lithography machine, specific anti-counterfeiting and brand logo characters are lithographically formed on the front side (one side of transparent layer 11) of the fetal number substrate: after the ultraviolet light passes through the transparent layer 11, specific character information is formed on the colored layer 12; 3. Using a 20-300 watt CO2 laser machine, perform semi-perforated etching on the back of the tire number substrate (on the side of release film 3). During etching, use the laser beam of the laser machine to etch layer by layer on the non-character positions on the front side, sequentially etching through release film 3, initial adhesive layer 4, vulcanized adhesive layer 2, and colored layer 12, without etching through transparent layer 11. The etched content is barcode (or other code system), characters, markings, etc.

[0049] Tire factory application scenarios: 1. Remove the tire number from release film 3 and stick it on the tire blank or place it in the corresponding position in the mold; 2. During vulcanization, the tire rubber compound flows into the semi-hollowed-out barcode (or other code system) and characters under the high pressure of the mold, forming a perfect filling; 3. After vulcanization, the barcode (or other code system) and characters filled with black or colored rubber on the tire, along with the anti-counterfeiting and brand logo characters formed by photolithography, are perfectly displayed through the transparent layer 11 and can be directly identified by intelligent scanning equipment. Implementation Method C

[0050] This implementation method is an optimized design for economical tires, which omits the ultraviolet lithography process to achieve the optimal balance between cost and production efficiency. The specific steps are as follows: 1. An integrated carrier layer with a transparent layer 11 and a colored layer 12 is prepared. A vulcanized adhesive layer 2, a primary adhesive layer 4 and a release film 3 are sequentially laminated on the side of the colored layer 12 away from the transparent layer 11 to form a tire number substrate. 2. Using a 20-300 watt CO2 laser machine, perform semi-perforated etching on the back of the tire number substrate (on the side of release film 3). During etching, use the laser beam of the laser machine to etch layer by layer on the non-character positions on the front side, sequentially etching through release film 3, initial adhesive layer 4, vulcanized adhesive layer 2, and colored layer 12, without etching through transparent layer 11. The etched content is barcode (or other code system), characters, markings, etc.

[0051] Tire factory application scenarios: 1. Remove the tire number from release film 3 and stick it on the tire blank or place it in the corresponding position in the mold; 2. During vulcanization, the tire rubber compound flows into the semi-hollowed-out barcode (or other code system) and characters under the high pressure of the mold, forming a perfect filling; 3. After vulcanization, the barcode (or other code system) and characters filled with black or colored rubber on the tire are perfectly displayed through the transparent layer 11 and can be directly identified by intelligent scanning equipment.

[0052] This embodiment also proposes a method for using a tire label with integrated anti-wear sidewall adhesive and semi-hollowed-out characters, including the following steps: 1. Tire number removal: Peel the integrated tire number from one side of the release film 3 to expose the vulcanized adhesive layer 2 (if an initial adhesive layer 4 is provided, it will be exposed simultaneously). 2. Tire size fixing: Attach the integrated tire size with the vulcanized adhesive layer 2 to the preset position on the sidewall of the tire blank, or directly place the integrated tire size into the corresponding forming position on the sidewall of the tire vulcanization mold. 3. Vulcanization molding: The tire blank equipped with the integrated tire number is vulcanized. During the vulcanization process, the tire rubber material flows into the semi-hollowed-out font structure 13 of the integrated tire number under the high pressure of the mold and completes the filling. At the same time, the vulcanized adhesive layer 2 reacts with the tire sidewall rubber to fix the integrated tire number and the tire sidewall into one piece. 4. Finished Product Identification: After vulcanization, the outline of the barcode / character formed by the tire rubber filling the semi-hollowed-out font structure 13 is clearly displayed through the transparent layer 11, and the barcode / character can be directly identified and traced by intelligent barcode scanning equipment.

[0053] This method involves directly attaching the tire number to the tire blank or placing it into a mold after peeling off the release film 3. It is simple, convenient, and compatible with the production rhythm of tire factories' assembly lines, requiring no additional pre-treatment processes and improving production efficiency. During vulcanization, the high pressure of the mold ensures that the rubber material flows precisely into and completely fills the semi-hollowed-out lettering structure 13. Combined with the non-penetrating design of the semi-hollowed-out lettering structure 13, rubber overflow is completely prevented. The filled rubber material adheres to the transparent layer 11, forming a clear outline of the solid characters / barcode through the transparent layer 11, resulting in high recognizability. Simultaneously, the vulcanization reaction between the vulcanized adhesive layer 2 and the tire rubber integrates the tire number with the tire, ensuring the permanence of the tire number. After vulcanization, the tire number information can be directly identified by a smart barcode scanner, eliminating the need for manual transcription. This significantly improves the traceability efficiency of tire logistics, warehousing, and end-use, while avoiding the error rate associated with manual transcription.

[0054] Furthermore, the integrated tire number of this invention is applied to a dedicated location on the tire sidewall, unlike the barcode markings at the tire bead position in the prior art. This sidewall location remains visible even after the rim is assembled, allowing for traceability not only during production and logistics when the tire is not assembled, but also for real-time traceability when the tire is in use on the vehicle, enabling information control throughout the entire tire usage process. Moreover, when the integrated tire number is forcibly removed from the tire sidewall, a permanent raised and recessed imprint formed by the tire body rubber material remains on the tire sidewall surface, matching the semi-hollowed-out font structure 13. This raised and recessed imprint allows for secondary traceability identification of the tire, effectively avoiding the risk of the marking being altered or replaced, and improving the security and reliability of traceability.

[0055] Meanwhile, after the tire is subjected to friction from road sand and high-pressure washing during use, the transparent layer 11 can effectively protect the photolithographic barcode / character information underneath, preventing information wear and detachment. Even after use, recycled tires can still be identified normally by intelligent barcode scanning equipment without manual recording. This method is adaptable to the vulcanization processes of tires of different specifications and rubber types, has strong versatility, and can realize intelligent traceability of the entire life cycle of tires from production, transportation, use to recycling, improving the level of digital management in the tire industry. Difference from existing patents: The existing published patent CN202510088180.1 is a non-intaglio type anti-counterfeiting and anti-tampering tire bead barcode, which only targets the bead position of the tire. This position cannot be seen after the rim is assembled, and can only realize basic traceability before tire assembly, which cannot meet the traceability needs when the tire is in use online. Moreover, after the barcode label of this patent is forcibly peeled off, there is no permanent embossed imprint formed by the body rubber on the tire, which has the technical defect of label replacement and tampering. The integrated tire number of this invention is specifically designed for the tire sidewall position and can be seen normally after the rim is assembled. It takes into account both the production logistics traceability when the tire is not assembled and the full-process traceability when it is used online on the vehicle. Moreover, after the tire number is forcibly peeled off, a permanent embossed imprint formed by the body rubber will be left on the tire, which can realize secondary traceability. The structure eliminates the problem of identification alteration and replacement. At the same time, this invention solves the industry pain points of rubber overflow and barcode wear from the root. Compared with the existing technology, it has better practicality and anti-counterfeiting traceability.
