Description

Technical Field

[0001] This utility model relates to the field of RFID tag technology, and in particular to an RFID tag using a flexible printed paper antenna. Background Technology

[0002] Radio Frequency Identification (RFID) is a communication technology that can identify specific targets and read / write related data via radio signals without requiring mechanical or optical contact between the identification system and the target.

[0003] RFID tags are increasingly used in the Internet of Things. Existing RFID tags have a conductive metal film bonded to the substrate. When using them, the conductive metal film is peeled off and attached to the item. However, when peeling the conductive metal film off the substrate, the conductive metal film needs to be lifted up. But the existing conductive metal film is bonded to the substrate at a linear edge, making it inconvenient to lift the conductive metal film.

[0004] In view of this, we propose an RFID tag that uses a flexible printed paper antenna. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an RFID tag that uses a flexible printed paper antenna to solve the technical problem that the conductive metal film is inconvenient to lift because the edge of the conductive metal film is linear and the substrate is glued together.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design an RFID tag using a flexible printed paper antenna, including paper, conductive metal film and aluminum foil wire;

[0007] The paper material is made of environmentally friendly flexible printing material;

[0008] A conductive metal film is arranged in a groove on the outer side of the paper material;

[0009] Aluminum foil wires are arranged within the conductive metal film;

[0010] The conductive metal film has an adhesive layer on its inner side, and the inner side of the conductive metal film is bonded to the groove through the adhesive layer.

[0011] The conductive metal film has arc-shaped protrusions at both its front and rear ends, and the arc-shaped protrusions are located in the arc-shaped grooves opened at the front and rear ends of the groove.

[0012] Preferably, the outer end of the inner side of the arc-shaped protrusion is provided with a fastening groove;

[0013] The buckle groove has a triangular structure, and the top of the beveled surface of the buckle groove is aligned with the outer side of the arc-shaped protrusion.

[0014] Preferably, the conductive metal film has trapezoidal protrusions on both sides and trapezoidal grooves on both sides, with the trapezoidal protrusions matching the trapezoidal grooves.

[0015] Preferably, the trapezoidal protrusions on both sides of the conductive metal film are staggered.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, by setting arc-shaped protrusions and arc-shaped grooves, has an arc-shaped connecting line formed at the front and rear ends of the conductive metal film. When bending the paper, the arc-shaped connecting point causes the arc-shaped protrusion to curl up, providing a force point for tearing off the conductive metal film, which is convenient for tearing off the conductive metal film. This solves the problem that the conductive metal film 2 is inconvenient to lift up because the edge of the adhesive between the conductive metal film 2 and the substrate is linear.

[0018] 2. This utility model has the advantage of setting a buckle groove, which eliminates the need for adhesive bonding and makes it easier for the arc-shaped protrusion to lift up at the buckle groove.

[0019] 3. By setting trapezoidal protrusions, this utility model has the advantage of increasing the stability of the conductive metal film in the groove bonding, and the conductive metal film is not easy to detach when it is not to be torn off by hand. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] Example 1: An RFID tag using a flexible printed paper antenna, see [link / reference] Figures 1 to 4 It includes paper material 1, conductive metal film 2, and aluminum foil wire 3;

[0030] Paper material 1 is made of environmentally friendly flexible printing material; conductive metal film 2 is arranged in the groove 101 opened on the outside of paper material 1; aluminum foil wire 3 is arranged in the conductive metal film 2; wherein, the inner side of conductive metal film 2 is provided with adhesive layer 4, and the inner side of conductive metal film 2 is bonded to the groove 101 through adhesive layer 4; wherein, the front and rear ends of conductive metal film 2 are provided with arc-shaped protrusions 202, and the arc-shaped protrusions 202 are arranged in the arc-shaped grooves 103 opened at the front and rear ends of groove 101.

[0031] This invention, by setting an arc-shaped protrusion 202 and an arc-shaped groove 103, forms an arc-shaped connecting line at the front and rear ends of the conductive metal film 2. When the paper material 1 is bent, the arc-shaped connecting point causes the arc-shaped protrusion 202 to curl up, providing a force point for tearing off the conductive metal film 2, which is convenient for tearing off the conductive metal film 2. This solves the problem that the conductive metal film 2 is inconvenient to lift because the edge of the adhesive bond between the conductive metal film 2 and the substrate is linear.

[0032] Specifically, a groove 2021 is provided at the outer end of the inner side of the arc-shaped protrusion 202; wherein, the groove 2021 has a triangular structure, and the top of the inclined surface of the groove 2021 is aligned with the outer side of the arc-shaped protrusion 202.

[0033] This utility model has the advantage that by setting the buckle groove 2021, the buckle groove 2021 is not glued, and the arc-shaped protrusion 202 is more likely to be lifted up at the buckle groove 2021.

[0034] Furthermore, trapezoidal protrusions 201 are provided on both sides of the conductive metal film 2, and trapezoidal grooves 102 are provided on both sides of the groove 101. The trapezoidal protrusions 201 and the trapezoidal grooves 102 are matched; the trapezoidal protrusions 201 on both sides of the conductive metal film 2 are staggered.

[0035] This invention, by setting trapezoidal protrusions 201, has the advantage of increasing the stability of the conductive metal film 2 in the groove 101, and making it less likely to detach when the conductive metal film 2 is not to be torn off by hand.

[0036] Working principle: Using the device of this utility model, the flexible printed paper material 1 is wound up. When it is necessary to peel off the conductive metal film 2, the paper material 1 of the corresponding area is pulled out and the paper material 1 at the corresponding part of the arc protrusion 202 is bent. The arc protrusion 202 is raised at the groove 2021. The raised arc protrusion 202 provides the force point for peeling off the conductive metal film 2. After peeling off the conductive metal film 2 by pulling the raised arc protrusion 202, it can be attached to the required position.

[0037] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
