Description
Technical Field
[0001] This utility model relates to the field of electronic tag technology, and more specifically, to an electronic tracking self-adhesive tag with an integrated RFID chip. Background Technology
[0002] With the rapid development of IoT technology, various industries have placed higher demands on the accuracy and efficiency of goods tracking and management. In the logistics field, the entire supply chain, from production, warehousing, and transportation to the sales terminal, requires real-time monitoring of the location and status of goods. RFID tags enable rapid, long-distance, batch reading, greatly improving the efficiency of inventory counting and transportation monitoring, and reducing errors and time costs associated with manual counting. For example, in large e-commerce warehouses, the management of large quantities of goods entering and leaving the warehouse can be precise and efficient using RFID tags, ensuring real-time accuracy of inventory data.
[0003] There are many existing technologies for electronic tags, such as:
[0004] According to Chinese patent application number CN202220586714.5, specifically, a high-temperature and acid / alkali resistant ultra-high frequency flexible electronic tag is disclosed, comprising an INLAY electronic tag, an upper protective film layer, a lower protective film layer, an adhesive layer, a buffer layer, and a silicone paper layer. The lower protective film layer is located at the bottom of the INLAY electronic tag, and a buffer layer is disposed between the INLAY electronic tag and the inner wall of the lower protective film layer. An adhesive layer is disposed on the lower surface of the lower protective film layer, and a silicone paper layer is disposed on the lower surface of the adhesive layer. An adhesive layer is located at the top of the INLAY electronic tag, and an upper protective film layer is disposed above the adhesive layer. This invention is resistant to high temperatures, acid and alkali corrosion, and high pressure. It is also ultra-thin, flexible, and sewn onto fabric, enabling the binding of fabric and electronic tag information for tracking and management.
[0005] In traditional technology, the chip is directly encapsulated inside the material. The protection of the chip depends on the pressure resistance of the external material. Without special protection for the chip, changes in the external environment can easily affect the chip's lifespan. Furthermore, the impact of the external environment on the label cannot be clearly seen, making it inconvenient to quickly replace expired labels later. Utility Model Content
[0006] This utility model addresses the technical problems existing in the prior art by providing an electronic tracking self-adhesive label with an integrated RFID chip. It solves the problems of traditional technologies having poor chip protection, affecting chip lifespan, and making it inconvenient to observe whether the label is working properly in a more intuitive way.
[0007] To achieve the above objectives, this utility model provides an electronic tracking self-adhesive label with an integrated RFID chip, comprising a substrate, an antenna layer disposed on the top of the substrate, a chip protective layer disposed on the top of the antenna layer, a chip fixedly connected to the lower end inside the chip protective layer, a surface layer disposed on the outside of the chip protective layer, the chip protective layer being adhered to the inside of the surface layer by an adhesive layer, temperature and humidity sensitive indicator strips symmetrically disposed on the top of the surface layer, and a self-adhesive layer coated on the bottom of the substrate.
[0008] The beneficial effects of this utility model are:
[0009] 1. Before use, the label is protected by a release paper layer, which has good peeling properties and can be easily peeled off when applying the label, thus providing effective protection for the label before use.
[0010] 2. During the use of the label, the chip protective layer effectively protects the chip, ensuring its lifespan. The temperature and humidity sensitive indicator strip detects the temperature and humidity in the external environment, making it easier for staff to observe the impact of the external environment on the label and improving the ease of use of the label.
[0011] Based on the above technical solution, the present invention can be further improved as follows.
[0012] Preferably, the antenna layer is a composite structure of metal mesh and conductive polymer, the surface layer has a window, and the adhesive layer has glass fiber microfilaments.
[0013] The advantages of adopting the above-mentioned further solutions are that the label has better strength and flexibility, making it easier to stick to the surface of various curved objects, and the influence on the signal is lower when bent, ensuring the stable use of the label.
[0014] Preferably, the chip protective layer is made of epoxy resin, and the adhesive layer is made of silicone potting compound.
[0015] The advantages of adopting the above-mentioned further solution are that it can effectively prevent the chip from being interfered with by external electric fields. At the same time, it has high chemical stability, is resistant to corrosion by acids, alkalis and other chemicals, and also has a certain degree of flexibility, which can adapt to the slight deformation of the chip in different environments, enhance the chip's shock resistance, and strengthen signal coupling.
[0016] Preferably, a release paper layer is provided at the bottom of the self-adhesive layer, and an edge-binding layer is fixedly connected to the outer side of the substrate, antenna layer, surface layer and self-adhesive layer.
[0017] The advantages of adopting the above-mentioned further solutions are that the release paper layer can protect the adhesive before use, and the release paper has good peeling performance, so it can be easily peeled off when applying the label. The edge wrapping layer solves the problem of easy warping of the edges of traditional labels and improves the number of bending cycles.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] The chip is protected by a protective layer made of epoxy resin, which effectively prevents the chip from being affected by external electric fields. Simultaneously, its high chemical stability, resistance to corrosion from acids, alkalis, and other chemicals, and its flexibility allow it to adapt to minor deformations of the chip in different environments, providing buffering protection. Furthermore, the excellent sealing properties of epoxy resin prevent moisture and dust from entering, avoiding short circuits or oxidation of the chip and extending its lifespan. Changes in the temperature and humidity sensitive indicator strip provide convenient indication of whether the label is functioning properly, facilitating staff observation and subsequent label maintenance.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-4 As shown, this embodiment provides an electronic tracking self-adhesive label with an integrated RFID chip, including a substrate 1. An antenna layer 2 is disposed on the top of the substrate 1. Considering that in traditional technology, the chip 31 is directly encapsulated inside the material, the protection effect of the chip 31 depends on the compressive strength of the external material. Without special protection for the chip 31, changes in the external environment can easily affect the lifespan of the chip 31. Therefore, a chip protection layer 3 is disposed on the top of the antenna layer 2. The chip 31 is fixedly connected to the lower end of the chip protection layer 3. A surface layer 4 is disposed on the outer side of the chip protection layer 3. The chip protection layer 3 is adhered to the surface layer 4 by an adhesive layer 42. During use, the chip protection layer 3 independently protects the chip 31. To protect and extend the lifespan of chip 31, and considering that traditional labels cannot visually indicate the impact of the external environment on the label, making it inconvenient to quickly replace failed labels later, a temperature and humidity sensitive indicator strip 43 is symmetrically set on the top of the surface layer 4. When the label absorbs temperature and humidity in the environment after long-term use, and exceeds the critical value (such as temperature > 40℃ or humidity > 80%), the indicator strip changes from blue to red, indicating that the label is in an abnormal state and may not be able to read information. It is no longer necessary to test whether the label can be used. By observing the temperature and humidity sensitive indicator strip 43, the usage status of the label can be quickly determined and then replaced. The bottom of the substrate 1 is coated with an adhesive layer 5.
[0033] The improvement of this embodiment is that the chip 31 is protected by the chip protective layer 3, which can effectively prevent the chip 31 from being interfered with by the external electric field. It can adapt to the slight deformation of the chip 31 in different environments, play a buffer protection role for the chip 31, prevent moisture, dust and other substances from entering, avoid short circuit or oxidation of the chip 31, and improve the overall service life of the chip 31. In addition, the change of temperature and humidity sensitive indicator strip 43 can help to indicate whether the label can be used normally, which is convenient for staff to observe and maintain the label later.
[0034] Specifically, considering the different sizes and shapes of items to be labeled in daily life, in order to achieve better adhesion of labels to items of different shapes, the antenna layer 2 is a composite structure of metal mesh and conductive polymer, which has better flexibility and is easy to stick to the surface of various curved items. It also has less impact on the signal when bent, ensuring the stable use of the label. In addition, a window 41 is set inside the surface layer 4, so that part of the antenna layer 2 can be exposed to the external environment, increasing the signal transmission effect.
[0035] To ensure effective protection for chip 31, the chip protective layer 3 is made of epoxy resin, which effectively prevents chip 31 from being interfered with by external electric fields. Simultaneously, it has high chemical stability, is resistant to corrosion from acids, alkalis, and other chemicals, and also possesses a certain degree of flexibility, adapting to the slight deformation of chip 31 in different environments, thus providing buffer protection for chip 31. Furthermore, epoxy resin has good sealing properties, preventing moisture and dust from entering and avoiding short circuits or oxidation of chip 31. The adhesive layer 42 uses silicone potting compound, enhancing the shock resistance of chip 31 and strengthening signal coupling.
[0036] To enhance the lifespan of the label, glass fiber microfilaments 51 are incorporated within the self-adhesive layer 5. This improves the label's strength and toughness, reduces deformation, enhances its anti-aging properties, and to a certain extent, improves the electrical insulation performance of the self-adhesive label. This prevents the RFID chip 31 inside the label from being interfered with by external electric fields, ensuring the normal operation of the electronic tracking function. A release paper layer 6 is placed at the bottom of the self-adhesive layer 5, covering the adhesive layer. This protects the adhesive before use, and the release paper has excellent peeling properties, allowing for easy removal when applying the label. An edge-wrapping layer 7 is fixedly connected to the outer sides of the substrate 1, antenna layer 2, surface layer 4, and self-adhesive layer 5, solving the problem of easy warping at the edges of traditional labels and increasing the number of bending cycles.
[0037] In summary, the working principle of this solution is as follows:
[0038] First, the chip 31 has a specific storage area that stores information related to the tracked item, such as product name, model, production batch, production date, and shelf life. This information is written into the chip 31 using specialized equipment during the label production process or before use. Each label has a unique identification code, like an item's "ID card." Then, the release paper layer 6 is peeled off, allowing the label to be adhered to the surface of the item through the self-adhesive layer 5. The glass fiber microfilaments 51 in the self-adhesive layer 5 improve the label's strength and toughness, reduce deformation, and enhance its anti-aging properties. They also improve the electrical insulation performance of the self-adhesive label to a certain extent, preventing interference from external electric fields to the RFID chip 31 inside the label and ensuring the normal operation of the electronic tracking function. During use, the chip protective layer 3 protects the chip 31. The chip protective layer 3 is made of epoxy resin, which effectively prevents the chip 31 from being interfered with by external electric fields. Simultaneously, it has high chemical stability, is resistant to corrosion from acids, alkalis, and other chemicals, and possesses a certain degree of flexibility, adapting to the slight deformation of the chip 31 in different environments, thus providing buffer protection for the chip 31. In addition, epoxy resin has good sealing properties, which can prevent moisture, dust and other substances from entering, avoid short circuits or oxidation of chip 31, and improve the service life of chip 31. The temperature and humidity sensitive indicator strip 43 detects the temperature and humidity in the external environment. When the label absorbs the temperature and humidity in the environment after a long period of use, and exceeds the critical value (such as temperature > 40℃ or humidity > 80%), the indicator strip changes from blue to red, indicating that the label is in abnormal use and may not be able to read information. It is no longer necessary to test whether the label can be used. By observing the temperature and humidity sensitive indicator strip 43, the use status of the label can be quickly determined and then replaced.
