Description

Technical Field

[0001] This utility model belongs to the technical field of REID tags, and specifically relates to a REID tag. Background Technology

[0002] RFID tags, or Radio Frequency Identification tags, are electronic tags that use radio frequency signals to achieve contactless, two-way data transmission. They typically consist of a chip and an antenna. The chip stores item information, while the antenna handles signal transmission and reception. During operation, the tag receives radio frequency signals from a reader and relays item information, enabling rapid identification and data exchange. Compared to traditional barcode tags, RFID tags offer advantages such as rewritability, long reading distance, the ability to process multiple tags simultaneously, and strong anti-interference capabilities, making them widely used in logistics warehousing, retail management, and transportation ticketing.

[0003] Traditional RFID tags mostly use a flat adhesive design with a single adhesive strength. Due to the presence of internal chips and antennas, they are prone to peeling and air bubbles when pasted on curved or irregular surfaces, leading to unstable signal reading. In scenarios such as cylindrical gas cylinders and irregularly shaped packaging boxes, the effective adhesion rate of existing tags is low, and the signal reading success rate is reduced. Utility Model Content

[0004] The purpose of this invention is to provide a RFID tag to address the problems in the background art where existing traditional RFID tags mostly use a planar adhesive design with a single adhesive strength. Due to the presence of internal chips and antennas, these tags are prone to peeling and air bubbles when pasted on curved or irregular surfaces, leading to unstable signal reading. Furthermore, in scenarios such as cylindrical gas cylinders or irregularly shaped packaging boxes, existing tags suffer from low effective adhesion rates and reduced signal reading success rates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a REID tag, comprising a cardboard layer and a chip body disposed in the middle of the upper side of the cardboard layer;

[0006] Antennas are provided on the left and right sides of the chip body respectively;

[0007] The upper side of the cardboard layer is provided with coated paper;

[0008] The lower outer side of the cardboard layer is provided with an upper adhesive paper, and the upper middle side of the upper adhesive paper is provided with a collar seat. A retaining ring is provided at the connection between the cardboard layer and the collar seat.

[0009] A bottom adhesive paper is provided on the lower side of the top adhesive paper.

[0010] Preferably, the chip body and the antenna are connected by adhesive bonding and cardboard layer, respectively.

[0011] Preferably, the retaining ring and the cardboard layer are bonded together by adhesive, and the collar seat and the upper adhesive paper are fixedly connected.

[0012] Preferably, the retaining ring is connected to the retaining ring seat by a nesting connection, and the cardboard layer can rotate within the retaining ring.

[0013] Preferably, the base adhesive paper and the top adhesive paper are bonded together, the coated paper and the cardboard layer are bonded together by filling with glue, and the chip body and the antenna are respectively wrapped inside the glue.

[0014] Preferably, a label is provided on the right rear side of the cardboard layer, and a label area is provided on the left side of the label.

[0015] Compared with the prior art, the present invention provides a REID tag with the following advantages:

[0016] 1. This innovative structure allows the tag to adapt to various complex surface shapes. Whether it's curved glass bottles, arc-shaped metal components, or uneven plastic products, the adhesive paper adheres tightly thanks to the high adaptability of the acrylic pressure-sensitive adhesive and the flexibility of the PET support film. Simultaneously, the cardboard layer, through its interlocking and rotating design of the retaining ring and collar seat, allows for flexible angle adjustment after application, solving the problem of unstable signal reading caused by poor adhesion angles in traditional RFID tags. This enables the tag to efficiently complete information identification in various scenarios such as warehouse inventory checks and logistics transportation, greatly expanding its application scope.

[0017] 2. The three-layer composite adhesion system of the top adhesive paper and the bottom adhesive paper not only has good initial tack, but also strengthens the intermolecular forces over time, ensuring that the label adheres firmly to the surface of the item for a long time. The excellent tear resistance and elastic deformation ability of the PET support film can effectively resist the stress caused by thermal expansion and contraction and external pressure on the surface of the item, preventing the adhesive layer from failing. In addition, the mechanical interlocking and molecular-level bonding structure formed by the coated paper and cardboard layers through adhesive filling provides double protection for the chip body and antenna. Even under external impact of -N, it can ensure the stability of RFID signal transmission, extend the life of the label, and reduce the risk of information identification failure due to label damage.

[0018] 3. During use, simply peel off the backing paper to quickly attach the label; the operation is simple and convenient. When the label angle needs to be adjusted, there is no need to reattach it; simply rotate the cardboard layer manually to complete the adjustment. In large-scale warehouse inventory operations, this design can reduce the angle adjustment time for each label from several minutes in the traditional method to a few seconds, thereby improving signal strength, significantly increasing inventory efficiency, reducing labor costs, and enhancing the smoothness of the overall workflow.

[0019] 4. The innovative design utilizes common industrial materials such as polycarbonate, POM engineering plastics, and acrylic pressure-sensitive adhesive, along with mature processes like injection molding, dispensing, and screen printing. This simplifies production and facilitates large-scale manufacturing. Compared to some RFID tags employing complex structures and special materials, this significantly reduces production costs. Furthermore, the stable and durable tag structure minimizes frequent replacements due to damage, lowering maintenance and time costs and resulting in excellent economic benefits.

[0026] 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.

[0027] This utility model provides, for example Figure 1-5 The REID tag shown includes a cardboard layer 4, a chip body 5 disposed in the middle of the upper side of the cardboard layer 4, antennas 6 disposed on the left and right sides of the chip body 5, and coated paper 9 disposed on the upper side of the cardboard layer 4.

[0028] The cardboard layer 4 has a label 7 on its right rear side, a label area 8 on its left side, a bottom adhesive paper 1 and an upper adhesive paper 2 are attached together, a coated paper 9 and a cardboard layer 4 are connected by glue, and the chip body 5 and the antenna 6 are respectively wrapped inside the glue. The chip body 5 and the antenna 6 are respectively connected to the cardboard layer 4 by glue.

[0029] In this embodiment, when using a REID tag without innovative structural features, the chip body 5 and antenna 6 are first adhered to the upper middle and left and right sides of the cardboard layer 4 using adhesive to form a data transmission core. Then, coated paper 9 is covered onto the cardboard layer 4 using adhesive filler. The coated paper 9 not only protects the chip body 5 and antenna 6 from external physical damage but also provides a smooth surface for printing various markings. Simultaneously, a label 7 is placed on the right rear side of the cardboard layer 4. The label area 8 on its left side can be manually filled in or printed with information such as product name, specifications, and batch number, enabling human-readable information labeling.

[0030] In use, the tag is directly attached to the surface of the item. When the external RFID reader sends a signal, the antenna 6 receives the signal and transmits it to the chip body 5. After the chip body 5 responds, it feeds back the stored item information to the reader, thereby completing the identification and reading of the item information.

[0031] like Figure 1-5 As shown, an upper adhesive paper 2 is provided on the lower outer side of the cardboard layer 4, a collar seat 3 is provided on the upper middle side of the upper adhesive paper 2, and a retaining ring 10 is provided at the connection between the cardboard layer 4 and the collar seat 3.

[0032] The bottom adhesive paper 1 is provided on the lower side of the top adhesive paper 2. The retaining ring 10 and the cardboard layer 4 are connected by adhesive. The collar seat 3 is fixedly connected to the top adhesive paper 2. The retaining ring 10 is connected to the collar seat 3 by a nesting connection method, and the cardboard layer 4 can rotate in the collar through the retaining ring 10.

[0033] Preferably, when affixing labels to irregularly shaped items such as curved glass bottles or arc-shaped metal components, the worker first carefully peels off the backing paper 1 along the edge seam between the backing paper 1 and the top adhesive paper 2. At this point, the adhesive surface of the top adhesive paper 2 is fully exposed. The top adhesive paper 2 uses acrylic pressure-sensitive adhesive, which has moderate tack and good initial tack, allowing for quick adhesion even on surfaces with slight dust or unevenness. Taking the application to a mineral water bottle as an example, the top adhesive paper 2 is aligned with the curved surface of the bottle and pressed down. The adhesive surface naturally extends and deforms with the curve, forming a strong adhesion within 3-5 seconds, ensuring that the label does not easily fall off.

[0034] When adjusting the tag angle to optimize RFID signal reception, operators can simply pinch the edge of cardboard layer 4 with their fingers and apply a gentle rotational force without any tools. Because the retaining ring 10 and the collar seat 3 employ a precise interlocking design, with a clearance controlled between 0.05-0.1mm, cardboard layer 4 can rotate freely 360° within the collar seat 3, and the rotation process is smooth and seamless. For example, in warehouse inventory scenarios, if the initial tag angle results in a weak reader signal, adjusting cardboard layer 4 to the optimal position can improve signal strength by 30%-50%, significantly increasing inventory efficiency.

[0035] The ingenuity of this innovative structure lies in the synergistic work and complementary functions of its components. The adhesion system between the top adhesive paper 2 and the bottom adhesive paper 1 adopts a three-layer composite structure: the bottom layer is the release paper, i.e., the bottom adhesive paper 1; the middle layer is an acrylic pressure-sensitive adhesive; and the top layer is a PET support film, i.e., the top adhesive paper 2. When the bottom adhesive paper 1 is peeled off, the pressure-sensitive adhesive comes into contact with the surface of the object. The polymer chains in the adhesive layer interact with the molecules on the surface of the object through van der Waals forces. Over time, the intermolecular forces continuously strengthen, forming a durable and strong adhesive effect. At the same time, the PET support film has excellent flexibility and tear resistance. When the surface of the object is deformed, such as by thermal expansion and contraction or by external extrusion, it can absorb stress through its own elastic deformation, avoiding adhesive failure due to excessive stretching or compression.

[0036] The connection design between the collar seat 3 and the retaining ring 10 is the core of enabling the label to rotate flexibly. The collar seat 3 is made of high-strength polycarbonate injection molding, and its inner wall is precision polished, with a surface roughness Ra≤0.4μm. The retaining ring 10 is made of wear-resistant POM engineering plastic and is firmly bonded to the cardboard layer 4 through a secondary injection molding process. When the cardboard layer 4 rotates, the retaining ring 10 makes a circular motion within the collar seat 3. The friction between the two is minimal, and since the collar seat 3 is fixed to the upper adhesive paper 2, the connection structure between the retaining ring 10 and the cardboard layer 4 effectively blocks the stress transmission caused by the deformation of the upper adhesive paper 2, keeping the cardboard layer 4 in a relatively stable state.

[0037] Furthermore, the adhesive filling connection between the coated paper 9 and the cardboard layer 4 further enhances structural stability. During the curing process, the adhesive penetrates into the fiber pores of the cardboard layer 4 and the micropores of the coating of the coated paper 9, forming a mechanically interlocking structure, while simultaneously achieving molecular-level bonding through chemical bonding. This composite structure provides dual protection for the chip body 5 and the antenna 6, effectively dispersing stress even when the tag is subjected to an external impact force of 10-20N, preventing damage to the chip and antenna, and ensuring the long-term stability and reliability of RFID signal transmission.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
