Abstract
Description
Technical Field
[0001] This utility model relates to the field of label technology, specifically to a semi-engraved barcode vulcanized label with a surface coating. Background Technology
[0002] A barcode label is a label printed with barcode symbols. It identifies items using barcode technology. It consists of a set of regularly arranged bars, spaces and corresponding characters. It can store information such as product name, specifications, price, and place of origin. It is commonly used in scenarios such as commodity circulation, warehouse management, and logistics transportation. It can achieve rapid scanning and identification, and improve information processing efficiency.
[0003] Tires are ring-shaped elastic rubber products mounted on wheel rims, used for vehicle support, shock absorption, and drive. Tires require vulcanization during production. Tire vulcanization is a process that uses heat and pressure to crosslink raw rubber into vulcanized rubber, giving tires strength and elasticity.
[0004] Because industry regulations require complete recording of production data, and smart manufacturing drives digital upgrades, the demand for tire lifecycle management has emerged. Therefore, barcode labels are also applied to tires. However, the tire vulcanization process has strict requirements for parameters such as temperature and pressure.
[0005] Traditional paper labels are not heat-resistant, metal signs affect dynamic balance and may damage molds, barcode labels are prone to deformation after vulcanization, existing surface-printed labels are prone to corrosion and wear, and RFID and laminated labels are costly.
[0006] A tire RFID tag with application number CN220604036U, applicable to the vulcanization process, includes a base rubber, a PCB board, a chip, two connection points, and two antennas. The PCB board is fixedly connected to the base rubber and located above it. The chip is also fixedly connected to the PCB board and located above it. Both connection points are fixedly connected to the chip and symmetrically arranged at both ends of the chip. The two antennas are fixedly connected to the two connection points respectively and are located on the sides of the two connection points, with the two antennas arranged in a wavy shape. This design solves the problems of tag breakage and inability to be identified due to complex road conditions during daily vehicle driving, as well as the problems of excessively large tag size causing uneven stress inside the tire rubber, affecting tire safety and service life.
[0007] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: In the traditional tire vulcanization process, the use of release agents can cause the printed barcodes on the surface to become blurry, directly resulting in the loss of key information. Furthermore, during long-term use, the barcodes are prone to wear and tear, which seriously affects the efficiency of information reading and the normal operation of warranty services. In addition, fully engraved vulcanized barcodes have a technical bottleneck of insufficient engraving precision, especially in small-area label application scenarios, making it difficult to meet the needs of refined production. Utility Model Content
[0008] To address the aforementioned shortcomings of existing technologies, this invention provides a semi-engraved barcode vulcanized label with a surface coating, which effectively solves the problems of blurred barcodes due to corrosion by tire vulcanizing agents, information loss due to long-term wear, and insufficient precision of full engraving technology in small-area label applications.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] This utility model provides a semi-engraved barcode vulcanized label with a surface coating, comprising: a carrier layer, wherein a bottom adhesive component is sequentially stacked at the bottom of the carrier layer, the bottom adhesive component comprising a special base adhesive layer, a strong adhesive layer, a vulcanized adhesive layer, an adhesive layer and a release film layer, and a color developing coating is applied to the top of the carrier layer, wherein a barcode engraving groove is formed on the top of the carrier layer by ultraviolet laser engraving, and the engraving depth is controlled within 0.1mm ± 0.01mm.
[0011] Furthermore, the carrier layer is composed of a polyester film, which is a white PET substrate, and the color-developing coating makes the white PET polyester film in the engraved area appear black.
[0012] Furthermore, the ultraviolet laser engraving depth is strictly limited to 0.1mm±0.01mm, penetrating only the color coating and part of the carrier layer without damaging the underlying adhesive components, thus ensuring the stability of each layer structure during the vulcanization process.
[0013] Furthermore, the label is suitable for small-sized tire vulcanization scenarios with an area of less than 0.5 square centimeters, and overcomes the precision limitations of full engraving technology through a semi-engraving process.
[0014] Furthermore, the deep encoded data of the barcode engraving groove can still be read even after the surface barcode pattern is worn or corroded.
[0015] Furthermore, the special base layer is directly adhered to the bottom of the carrier layer, the vulcanized rubber layer is located between the strong rubber layer and the adhesive layer, the vulcanized rubber layer is used to adapt to the high temperature and high pressure environment of the tire vulcanization process, and the release film layer covers the surface of the adhesive layer.
[0016] Beneficial effects
[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:
[0018] I. This utility model, by setting up components such as a color-developing coating and a barcode engraving groove, and through the coordination between the ultraviolet laser engraving depth and the carrier layer and the color-developing coating, enables the barcode engraving groove to maintain the clarity of the surface barcode pattern and the readability of the deep barcode data by precisely engraving that only penetrates the color-developing coating and part of the carrier layer. Thus, this device can solve the problems of barcode blurring and easy surface wear caused by release agents through the color-developing coating and semi-engraving process.
[0019] II. By setting up a carrier layer, a bottom adhesive component, and other components, and through the interaction between the vulcanized adhesive layer, the strong adhesive layer, and the adhesive layer, this utility model ensures the adhesion stability between the label and the tire by adapting the vulcanized adhesive layer to the high temperature and high pressure environment of the tire vulcanization process. Thus, this device can solve the problems of traditional labels being unable to withstand high temperatures and easily deforming after vulcanization through the multi-layer structure design of the bottom adhesive component.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0027] The present invention will be further described below with reference to the embodiments.
[0028] See attached document Figure 1-4 A semi-engraved barcode vulcanized label with a surface coating includes: a carrier layer 1; a bottom adhesive component 3 is sequentially stacked at the bottom of the carrier layer 1; the bottom adhesive component 3 includes a special base adhesive layer 31, a strong adhesive layer 32, a vulcanizing adhesive layer 33, an adhesive layer 34, and a release film layer 35; a color developing coating 4 is coated on the top of the carrier layer 1; a barcode engraving groove 2 is formed on the top of the carrier layer 1 by ultraviolet laser engraving, with the engraving depth controlled within 0.1mm ± 0.01mm, and without penetrating the strong adhesive layer 32 at the bottom of the carrier layer 1; the surface barcode pattern and deep coding data are etched by ultraviolet light to avoid surface wear; the barcode engraving groove 2 is for the engraving data of the barcode and the code; the carrier layer 1 provides basic support; and the special base adhesive layer 31 and the strong adhesive layer 32 in the bottom adhesive component 3 are used for the engraving data of the barcode and the code. The 32, 33, 34, and 35 vulcanized rubber layers work together to achieve a firm adhesion between the label and the tire and to adapt to the vulcanization process. The color-developing coating 4 makes the barcode pattern clearly visible. The carrier layer 1 is engraved with barcodes and codes through ultraviolet laser engraving to form barcode and code engraving grooves 2. The engraving depth of 0.1mm±0.01mm ensures structural stability and information readability. The carrier layer 1 is made of polyester film with a white PET substrate. The color-developing coating 4 makes the white PET polyester film in the engraved area appear black, which is convenient for the scanner to read the data. The white PET substrate carrier layer 1 ensures the physical properties of the label. The color-developing coating 4 is a special black coating that turns the laser-engraved barcode from white to black, significantly improving the scanning recognition rate and making it easier for scanning equipment to quickly and accurately read the barcode information.
[0029] The ultraviolet laser engraving depth is strictly limited to 0.1mm±0.01mm, penetrating only the color developing coating 4 and part of the carrier layer 1, without damaging the underlying adhesive components 3. This ensures the stability of each layer structure during the vulcanization process. The strictly limited ultraviolet laser engraving depth only penetrates the color developing coating 4 and part of the carrier layer 1, avoiding damage to the underlying adhesive components. This ensures the stability of each layer structure of the label during the tire vulcanization process and does not affect its performance. The label is suitable for vulcanization scenarios of small-sized tires with an area of less than 0.5 square centimeters, and the tire specifications and dimensions can be flexibly adjusted according to actual needs. By using a semi-engraving process, the precision limitations of full engraving technology are overcome, meeting the needs of refined production of small-area labels.
[0030] The deep coding data of the barcode engraving groove 2 can still be read even after the surface barcode pattern is worn or corroded, ensuring the long-term accessibility of the label information and improving the reliability of information reading. The special base adhesive layer 31 is directly adhered to the bottom of the carrier layer 1. The vulcanized adhesive layer 33 is located between the strong adhesive layer 32 and the adhesive layer 34. The vulcanized adhesive layer 33 is used to adapt to the high temperature and high pressure environment of the tire vulcanization process. The release film layer 35 covers the surface of the adhesive layer 34. The special base adhesive layer 31 is directly adhered to the bottom of the carrier layer 1. The vulcanized adhesive layer 33 is located between the strong adhesive layer 32 and the adhesive layer 34 to adapt to the high temperature and high pressure environment of the tire vulcanization process. The release film layer 35 covers the surface of the adhesive layer 34. The reasonable arrangement of each layer ensures that the label adheres stably during the vulcanization process and its performance is not affected.
[0031] Working principle: When in use, the release film layer 35 is first removed. Through the multi-layer structure of the adhesive layer 34, vulcanized rubber layer 33, strong adhesive layer 32 and special bottom adhesive layer 31 in the bottom adhesive component 3, the label is firmly adhered to the tire surface. When the tire vulcanization process is carried out, the vulcanized rubber layer 33, with its adaptability to high temperature and high pressure environment, ensures that the structure of each layer of the label is stable during the vulcanization process at 150-200℃, avoiding deformation or falling off due to temperature and pressure changes. At the same time, the adhesive component at the bottom of the carrier layer 1 will not be damaged by the engraving process.
[0032] The barcode engraving groove 2 of the label is semi-engraved by ultraviolet laser. The engraving depth is strictly controlled at 0.1mm±0.01mm, which only penetrates the color coating 4 and part of the carrier layer 1. During the laser engraving process, the color coating 4 makes the engraved area of the white PET substrate appear black, forming a clear surface barcode pattern and coding data.
[0033] During long-term use, when the label surface wears down due to friction or corrosion, the data can still be recognized by the reading device. Since the ultraviolet laser engraving does not damage the underlying adhesive component 3, the adhesion stability between the label and the tire is not affected. Even if the surface barcode pattern is blurred, the deep data can still ensure the traceability of information throughout the tire's entire life cycle. This solves the problem of information loss caused by the corrosion of release agent and physical wear of traditional labels. At the same time, the semi-engraving process breaks through the precision limitations of small-area labels, meeting the needs of intelligent manufacturing for digital tire management.
[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
