Description

Technical Field

[0001] The utility model belongs to the technical field of RFID electronic tags, and in particular relates to an anti-interference RFID electronic tag. Background Art

[0002] RFID tags that store information serve as data carriers. They achieve contactless coupling of radio frequency signals with readers through coupling elements, realize the function of data exchange, and achieve the purpose of identifying targets. They are often used in industries such as logistics management and access control.

[0003] At present, existing RFID electronic tags are often fixed to the surface of objects by bonding, but the adhesive is prone to aging under the influence of light, heat, air and other factors, resulting in reduced adhesive viscosity and label shedding.

[0004] Therefore, in order to solve the problem that the adhesive of the existing RFID electronic tags fixed by adhesives ages under the influence of the external environment during use, causing the RFID electronic tags to fall off, the existing RFID electronic tags are improved by fixing the RFID electronic tags on the surface of the object through an installation base to prevent the tags from falling off. Utility Model Content

[0005] In order to overcome the problem that the existing RFID electronic tags are fixed on the surface of the object by bonding, and the adhesive ages under the influence of the external environment, causing the RFID tag to fall off.

[0006] The technical solution of the utility model is: an anti-interference RFID electronic tag, including a mounting base, a storage slot, an RFID tag, a protective component, and a wave-absorbing and anti-interference pad; four anchor holes are opened on the mounting base, a storage slot is opened on the surface of the mounting base, an RFID tag is arranged inside the storage slot, a protective component is movably connected in the storage slot, the RFID tag is placed in the protective component, and the wave-absorbing and anti-interference pad is arranged in the protective component.

[0007] Preferably, the mounting base is anchored on the surface of the object instead of the original RFID tag bonding and fixing method to avoid aging of the adhesive and prevent the RFID tag from falling. The protective component can protect the RFID tag from damage, and the wave-absorbing and anti-interference pad can change the magnetic field of the RFID tag to prevent it from being affected by metal materials.

[0008] Preferably, a storage groove matching the shape of the protective component is provided on the front side of the mounting base, and two semi-arc grooves opposite to each other are provided on the front side of the mounting base. The protective component and the RFID tag installed in the protective component are stored in the storage groove, so as to reduce the space occupied by this design. The semi-arc groove allows the staff to extend their fingers to pinch the protective component and pull it out of the storage groove.

[0009] Preferably, the protective component includes a support plate and a protective frame; a support plate is arranged in the storage slot, and a protective frame composed of three outer edges is fixedly connected to the front side of the support plate. The length of the protective frame is shorter than the support plate, which is convenient for installing the buckles to fix the transparent protective film.

[0010] Preferably, the protection component also includes a transparent protective film; a transparent protective film located in front of the RFID tag is fixedly connected to the protection frame, the transparent protective film can protect the surface of the RFID tag, prevent the RFID surface from contacting the external environment, avoid wear on the RFID tag surface, extend the service life of the RFID tag, and at the same time, the information of the RFID tag can be read through the transparent protective film.

[0011] Preferably, four card slots are opened on the rear side of the support plate, and buckles matching the card slots are fixedly connected in the storage slots. The protective components can be snapped and fixed in the storage slots through the buckles and the card slots to prevent the protective components and the RFID tags from falling off together.

[0012] Preferably, a magnetic wave-absorbing and anti-interference pad is bonded to the back side of the RFID tag, and a limiting groove with the same thickness as the RFID tag to which the wave-absorbing and anti-interference pad is bonded is opened in the protective frame. The magnetic permeability of the wave-absorbing and anti-interference pad is higher than that of the metal material, so as to change the magnetic field environment of the RFID tag and avoid interference of the metal material to the electromagnetic waves emitted by the RFID tag. The limiting groove can limit and fix the position of the RFID tag to avoid the RFID tag shaking inside the protective component.

[0013] Preferably, a sub-buckle is installed on the support plate, and a female buckle matching the sub-buckle is installed on the back side of the transparent protective film. The other side of the protective film is fixed to the front side of the support plate through the sub-buckle and the female buckle to close the space between the protective frame and the support plate. In order to avoid signal interference, the sub-buckle and the female buckle cannot be made of metal, but should be made of plastic.

[0014] Beneficial effects of the utility model:

[0015] 1. By designing a mounting base that can be fixed on the surface of an object with screws, and installing the protective component and the RFID tag together in the mounting base, instead of the traditional fixing method of sticking with adhesives, the protective component can protect the RFID tag, prevent the RFID tag from contacting with the outside world, and prevent the surface of the RFID tag from being damaged;

[0016] 2. Generally, RFID tags are bonded and used on the surface of metal objects. The metal objects themselves will affect the working performance of the RFID tags. The electromagnetic waves emitted by the RFID tags will be isolated by the metal and the signals will be interfered with. By installing the base, the RFID electronic tags are separated from the metal objects, and the magnetic field environment of the RFID tags is changed by using the wave-absorbing anti-interference pad with higher magnetic permeability than the metal material to ensure that the reader can correctly receive the electromagnetic wave signal of the RFID electronic tag, thereby achieving the anti-interference effect.
