Detailed Description

Embedded Carrier Unit first embodiment

Referring to fig. 1 to 3, an embedded carrier unit 1 is used for mounting an RFID tag in a mounting hole provided on a product or a component, so as to effectively prevent the RFID tag from falling off and losing from the product or the component during the production, transportation or storage of the product or the component, thereby ensuring reliable tracking management of the product or the component. The embedded carrier unit 1 includes a carrier 11 and an elastic member 12.

The carrier 11 is substantially a cylinder, wherein the first end of the carrier 11 is provided with an accommodating position 111, in this embodiment, the accommodating position 111 is a second round hole, so that the carrier 11 can reliably fix the cylindrical RFID tag and prevent the RFID tag from falling off from the carrier 11. In the axial direction of the carrier 11, a second circular hole extends from the first end face of the carrier 11 to the second end face of the carrier 11. In addition, the carrier 11 is further provided with a first circular hole 112, a first slot hole 113 and a take-out hole 114. Preferably, the height of the side wall of the second circular hole in the axial direction of the carrier is less than 10 mm; further, in order to improve the sensitivity of the RFID tag, the accommodating portion 111 may be made flat, that is, the height of the sidewall of the second circular hole is 0 mm.

In the axial direction of the carrier 11, the first circular hole 112 extends from the bottom of the second circular hole to the second end of the carrier 11, and the diameter of the first circular hole 112 is smaller than that of the second circular hole, and the first circular hole 112 is used for accommodating the elastic element 12. The first slot 113 is formed on the side wall of the carrier 11, the first slot 113 is preferably a third round hole, and the first slot 113 is communicated with the first round hole 112. Further, in the axial direction of the carrier 11, the take-out hole 114 extends from the second end face of the carrier 11 toward the first end face of the carrier 11, and the take-out hole 114 communicates with the first circular hole 112; the taking-out hole 114 is provided so that when the RFID tag needs to be detached from the product or the component, a worker or a processing device can hook the carrier 11 out of the mounting hole by engaging the tool with the taking-out hole 114, and then take out the RFID tag together from the mounting hole of the product or the component, thereby making the detachment of the RFID tag simpler and more convenient.

Preferably, the second end face of the carrier 11 is provided with a magnetic surface 115, and the magnetic surface 115 may be formed integrally with the carrier 11; the surface of the magnet piece or the surface of the iron piece attached to the second end surface of the carrier 11 may be used. When the RFID tag is a metal-resistant RFID tag, the carrier 11 may be made of a metal material, such as iron, but may be made of other metal materials, and when the carrier 11 is made of iron, the second end surface of the carrier 11 may directly form the magnetic surface 115; preferably, when the carrier 11 is made of a metal material, when the carrier 11 is assembled with the anti-metal RFID tag, the metal sheet is mounted at the bottom of the accommodating position 111, and then the anti-metal RFID tag is mounted, and the wall height of the accommodating position 111 is made to be adapted to the performance characteristics of the anti-metal RFID tag, so that the anti-metal RFID tag is mounted on the surface of the metal body with a sufficiently large surface area, thereby improving the identification rate and sensitivity of the anti-metal RFID tag. Of course, in other embodiments, the second end face of the carrier 11 may be configured as a non-magnetic face, so that the carrier 11 can be taken out of the mounting hole of the product or the component by the suction cup; alternatively, the magnetic surface and the non-magnetic surface are molded together on the second end surface of the carrier 11.

When the RFID tag is a non-metal-resistant RFID tag, the carrier 11 is preferably made of a plastic material, so that the RFID tag can be correctly identified with high sensitivity, the carrier 11 has rigidity and strength meeting the use requirements, and the carrier 11 is lighter; in this case, the magnet piece or the iron piece may be adhesively fixed to the second end surface of the carrier 11 so that the surface of the magnet piece or the iron piece is the magnetic surface 115, but the magnet piece or the iron piece may be molded to the second end of the carrier 11 by a double injection molding method.

Further, the second end surface of the carrier 11 is coated with a teflon coating covering the magnetic surface or the non-magnetic surface, and the arrangement is such that when the product or the part needs to be subjected to powder spraying or paint spraying in the production process, the teflon coating arranged on the second end surface of the carrier can effectively prevent the powder or the paint from being attached to the second end surface of the carrier.

The elastic element 12 is installed in the first circular hole 112, in this embodiment, the elastic element 12 is a first spring element, the first spring element has a matching portion 121, the matching portion 121 passes through the first slot 113 and extends out of the carrier 11, and the matching portion 121 can move in the radial direction of the carrier 11. When it is desired to mount an RFID tag into a mounting hole on a product or component, the RFID tag is mounted to the receiving position 111 of the carrier 11; then, the carrier 11 is installed in the installation hole, when the carrier 11 is installed, the first end of the carrier 11 faces the bottom of the installation hole, and the bottom of the installation hole can be matched with the carrier 11 to limit the RFID tag, so that the RFID tag is prevented from falling off from the installation hole; during the process of mounting the carrier 11 into the mounting hole, the engaging portion 121 of the elastic element 12 is elastically deformed by the hole wall of the mounting hole and the carrier 11, so that the engaging portion 121 gradually retracts into the carrier 11; when the carrier 11 is inserted into the mounting hole, the matching portion 121 of the elastic member 12 abuts against the hole wall of the mounting hole to prevent the carrier 11 from being removed from the mounting hole, and further prevent the RFID tag from being lost in the production, transportation or storage process of the product or the component, so that the product or the component can be reliably tracked and managed. When it is desired to remove the RFID tag from the product or component, the carrier 11 may be hooked out of the mounting hole using the tool-fitting extraction hole 114, or the carrier 11 may be sucked out of the mounting hole by the magnet-fitting magnetic surface 115, or the carrier 11 may be sucked out of the mounting hole by the suction cup-fitting magnetic surface or non-magnetic surface.

Therefore, the embedded carrier unit is structurally designed, so that the RFID tag is simpler and more convenient to implant or take out, and products or parts are not easy to lose in the production, transportation or storage processes, so that reliable tracking management can be carried out on the products or the parts. In addition, when the mounting hole is arranged on the product or the part, in order to avoid influencing the appearance of the product or the part, the mounting hole is usually arranged on the inner side of the product or the part, and the RFID reader-writer usually reads and writes from the outer side of the product or the part when reading and writing the RFID tag on the product or the part, so that the embedded carrier unit provided by the utility model can fix the RFID tag in the mounting hole of the product or the part, and can also enable the RFID tag to be correctly identified with high sensitivity.
