Description

Technical Field

[0001] The utility model relates to the technical field of RFID electronic tags, and specifically to an RFID electronic tag with good fixing effect. Background Technique

[0002] RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies target objects through radio frequency signals and obtains relevant data. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can simultaneously identify multiple tags, with fast and convenient operation. The RFID electronic tag system consists of three parts:

[0003] Electronic tag: Composed of a coupling element and a chip, each tag has an electronic code, and high-capacity electronic tags have storage space that can be written by users, and are attached to objects to identify target objects;

[0004] Reader: A device that reads (and sometimes can also write) tag information, which can be designed as a handheld or fixed type;

[0005] Antenna: Transmits radio frequency signals between the tag and the reader;

[0006] The radio frequency signal space (non-contact) coupling between the electronic tag and the reader is realized through the coupling element; in the coupling channel, according to the timing relationship, the transfer of energy and data exchange are realized.

[0007] RFID electronic tags have different types according to different usage scenarios. Among them, there is an RFID screw tag. The RFID screw tag is mainly used to track and manage screws or other small parts. The RFID screw tag adopts a combination of a microchip and an antenna, which can associate screws with other items and interact with an RFID reader through wireless communication. The main advantage of the RFID screw tag is that it can realize automated screw tracking and management. By attaching tags to each screw, the position and status of each screw can be accurately tracked during the production process, which helps to improve production efficiency, reduce errors, and improve product quality.

[0008] The existing RFID screw tag is threadedly connected to an object through a screw part, and its connection and fixation are convenient and the connection force is strong. However, it is also easy to disassemble. Only by using a wrench to reverse-twist it can the disassembly be achieved. In this way, there will be a situation where it is reused after disassembly. This characteristic will be exploited by some lawless persons to transfer the RFID screw tag on the regular product packaging to the counterfeit product. In order to avoid this situation, an RFID electronic tag with good fixing effect is provided. Utility Model Content

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 3 , in the embodiment of the present invention, an RFID electronic tag with good fixing effect includes a bolt body 1 composed of a cylindrical nut 101 and a screw rod 102. The screw rod 102 is fixed to the bottom end of the cylindrical nut 101. A disassembly component 2 is arranged at the top of the cylindrical nut 101. The disassembly component 2 is used for inserting an external tool to install or disassemble the bolt body 1. An installation groove 3 penetrating to one side outside the cylindrical nut 101 is opened inside the cylindrical nut 101. An RFID electronic tag 4 is installed inside the installation groove 3. The disassembly component 2 includes an installation unit and a disassembly unit. The installation unit is used to provide a tool insertion space for the installation of the bolt body 1. The disassembly unit is used to provide a tool insertion space for the disassembly of the bolt body 1 and make the tool contact the RFID electronic tag 4 to cause indentations, so as to identify whether the bolt body 1 has been disassembled;

[0033] The installation unit includes an installation slot opening 202 and a second large arc surface 205. The installation slot opening 202 is opened at the top of the cylindrical nut 101. The second large arc surface 205 is formed at the top of one edge of the installation slot opening 202. When the external tool is inserted into the installation slot opening 202 and rotated in the direction towards the second large arc surface 205, the cylindrical nut 101 cannot be stressed. When the external tool is rotated in the direction away from the second large arc surface 205, the cylindrical nut 101 is stressed and rotated, so as to realize the one-way installation operation of the cylindrical nut 101;

[0034] The disassembly unit includes a disassembly slot opening 201 and a first large arc surface 203. The disassembly slot opening 201 is opened at the top of the cylindrical nut 101 and is vertically distributed with the installation slot opening 202. The disassembly slot opening 201 is communicated with the installation groove 3. When the tool is inserted into the disassembly slot opening 201, it contacts the surface of the RFID electronic tag 4 to form an indentation;

[0035] The first large arc surface 203 is formed at the top of one edge of the disassembly slot opening 201. The direction towards the first large arc surface 203 is in the opposite state to the second large arc surface 205. When the tool is inserted into the disassembly slot opening 201 and rotated in the direction towards the first large arc surface 203, the cylindrical nut 101 cannot be stressed. When the tool is inserted into the disassembly slot opening 201 and rotated in the direction away from the first large arc surface 203, the cylindrical nut 101 is stressed and rotated, so as to realize the one-way disassembly operation of the cylindrical nut 101;

[0036] The disassembly unit further includes a small arc surface 204, which is formed at the top of the other edge of the disassembly notch 201, and the radius of curvature of the small arc surface 204 is smaller than that of the first large arc surface 203. Through the small arc surface 204, the tool must be pressed deep into the disassembly notch 201 to apply a disassembly deflection force to the cylindrical nut 101, so as to cause an indentation on the RFID electronic tag 4;

[0037] There are two disassembly notches 201 and two installation notches 202, which are distributed along the circumference and are staggered with each other. The two disassembly notches 201 and the two installation notches 202 are linearly connected.

[0038] In this embodiment: when installing the bolt body 1, an external tool (for example, a flat head screwdriver) is inserted into the installation notch 202. At this time, the bolt body 1 can only be rotated by the external tool in the direction towards the original second large arc surface 205. This rotation direction is the same as the tightening direction of the screw 102, so that the installation of the bolt body 1 can be realized;

[0039] If you want to disassemble the bolt body 1, you can only insert an external tool into the disassembly notch 201. At this time, the external tool contacts the top of the RFID electronic tag 4, and then rotate the external tool in the direction of the small arc surface 204 to disassemble and turn the bolt body 1. During this process, in order to prevent the external tool from slipping out of the disassembly notch 201 through the small arc surface 204, a force towards the depth of the disassembly notch 201 needs to be applied to the external tool, so that the external tool closely adheres to the bottom of the disassembly notch 201, and then the external tool squeezes the RFID electronic tag 4, causing an indentation damage on the surface of the RFID electronic tag 4. Through this mark, it can be judged that this RFID bolt tag has been disassembled;

[0040] Through the cooperation of the above-mentioned multiple parts, it can be judged whether the RFID bolt tag is in the original installed state, effectively avoiding the situation of disassembly and transfer.

[0041] Please refer specifically to Figures 1 to 3 , the RFID electronic tag 4 is fixed to the inner side of the installation groove 3 by potting an ultra-high frequency RFID chip with epoxy resin. The depth of the disassembly notch 201 is greater than the depth of the installation notch 202, and the top of the epoxy resin protrudes into the inner side of the disassembly notch 201 and is lower than the lower surface of the installation notch 202.

[0042] In this embodiment: Epoxy resin potting has excellent high-temperature resistance and excellent adhesion. At the same time, the epoxy resin potting is relatively hard and brittle. When potting the epoxy resin, some small epoxy resin protrusions can be formed at the disassembly notch 201. When an external tool is inserted into the disassembly notch 201, these small epoxy resin protrusions will be squeezed and broken, so as to further improve the feature of the RFID bolt tag being disassembled;

[0043] In addition, it should be supplemented that: the width of the disassembly notch 201 can be set to be greater than the width of the end of a conventional external tool. In this way, after the external tool is inserted into the disassembly notch 201 and rotated, there is a certain deflection space, so as to better scratch or damage the epoxy resin.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
