Abstract
Description
Technical Field
[0001] This utility model relates to the field of RFID tag technology, specifically an RFID asset management tag. Background Technology
[0002] RFID tags (Radio Frequency Identification tags) are miniature wireless devices that use radio waves to transmit stored data to a nearby reader (RFID reader / writer). They are widely used in asset management and their core components include:
[0003] Chip / integrated circuit: Stores the tag's unique identifier (UID) and other relevant information (such as product model, production date, batch number, etc.);
[0004] Antenna: Used to receive radio wave energy from the reader and send the stored data signal back to the reader.
[0005] Substrate / Encapsulation: Protects the chip and antenna and attaches the entire label to the item. Encapsulation forms are diverse (stickers, cards, keychains, implants, special industrial encapsulation, etc.).
[0006] Its working principle is as follows: When an RFID tag enters the electromagnetic field range generated by the reader, the tag's antenna captures electromagnetic energy. This energy powers the tag chip (for passive tags) or activates its circuitry (for active tags). The chip uses the received energy to reflect its stored data back to the reader in the form of radio waves (for passive tags) or actively send it to the reader (for active / semi-active tags). After receiving the signal, the reader decodes it and transmits it to the backend computer system for processing and application.
[0007] In existing technologies, passive tags prevent transfer by permanently damaging the antenna or chip during forced removal, rendering the tag unreadable after transfer. This method leaves adhesive residue on the item's surface during the removal process. If the removal of passive tags is performed by management personnel (e.g., replacing tags due to antenna aging, upgrading to new tags, changing the attachment location, or changing information during item ownership transfer), cleaning up the adhesive residue will consume a significant amount of their time. To avoid this, an RFID asset management tag is provided. Utility Model Content
[0008] The purpose of this utility model is to provide an RFID asset management tag in order to solve the problems mentioned above.
[0009] To achieve the above objectives, this utility model provides the following technical solution: an RFID asset management tag, comprising a base shell assembly consisting of a sticker, a tag coating, and a residue-free adhesive layer. The tag coating is formed on the lower surface of the sticker by a printing process in the middle. The residue-free adhesive layer is coated on the lower surface of the sticker and located outside the area where the tag coating is located. The base shell assembly is adhered to the upper surface of the sticker. An anti-transfer component is provided on the inner side of the base shell assembly.
[0010] The base shell assembly provides a handheld part for the adhesion and peeling of the sticker, and the anti-transfer component is used to damage the sticker when it is peeled off, thereby achieving permanent damage to the label coating.
[0011] As a further embodiment of this utility model: the base shell assembly includes a top box, a notch groove, a horizontal sliding groove, and a fixing triangular retaining tooth;
[0012] The notch is formed at the bottom of the top box, the top box is glued and fixed to the upper surface of the sticker, and the notch is aligned with the area where the label coating is located;
[0013] The horizontal slide groove is formed at the front and rear ends of the outer wall of the top box. Two sets of the horizontal slide groove are symmetrically arranged with the center line of the top box as the center. The fixing triangular tooth is integrally formed at the bottom of the inner wall of the top box and extends to the top of the inner wall of the horizontal slide groove. The anti-transfer component is distributed on the inner side of the top box and the horizontal slide groove.
[0014] As a further improvement of this utility model: the anti-transfer component includes a horizontal push plate, elastic triangular teeth, and V-shaped spring sheet;
[0015] The horizontal push plate is symmetrically slidably connected to the inner side of two sets of horizontal slide grooves, and the elastic triangular locking teeth are fixed to the top of the horizontal push plate and are in a one-way locking state with the fixed triangular locking teeth.
[0016] The V-shaped springs are distributed inside the sticker and fixed in the middle of the two horizontal push plates, with the bottom of the V-shaped springs close to the top of the notch.
[0017] By bringing two horizontal push plates close together, the V-shaped spring is deformed and its bottom passes through the notch and contacts the upper surface of the sticker. When the sticker is peeled off, the V-shaped spring punctures the sticker.
[0018] As a further improvement of this utility model: an easy-tear dotted line is formed at the position where the sticker is aligned with the bottom of the V-shaped spring, and the easy-tear dotted line does not contact the label coating.
[0019] As a further improvement of this utility model, the V-shaped spring sheet has multiple evenly distributed straight slots along the longitudinal direction.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] By setting up a base shell component and an anti-transfer component, after the RFID tag is bonded to the object, the RFID tag is squeezed by the deformation of a V-shaped spring. When the RFID tag is peeled off, the elastic potential energy generated by the compression of the V-shaped spring is released, and the V-shaped spring will press down on the middle of the sticker, causing the middle of the sticker to tear. The label coating is simultaneously destroyed and broken, thus achieving the anti-transfer effect. At the same time, no residue will be left on the surface of the object, avoiding the need for subsequent cleaning of residual adhesive. Attached Figure Description

Detailed Implementation
[0027] 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.
[0028] Please see Figures 1-4 In this embodiment of the present invention, an RFID asset management tag includes a base shell assembly 1 composed of a sticker 201, a tag coating 202, and a residue-free adhesive layer 203. The tag coating 202 is formed on the lower surface of the sticker 201 by a printing process. The residue-free adhesive layer 203 is coated on the lower surface of the sticker 201 and located outside the area where the tag coating 202 is located. The base shell assembly 1 is adhered to the upper surface of the sticker 201. An anti-transfer component 3 is provided on the inner side of the base shell assembly 1.
[0029] The base shell assembly 1 provides a handhold for the adhesion and peeling of the sticker 201, and the anti-transfer assembly 3 is used to damage the sticker 201 when it is peeled off, thereby achieving permanent damage to the label coating 202.
[0030] The base shell assembly 1 includes a top box 101, a notch 102, a horizontal slide groove 103, and a fixing triangular retaining tooth 104;
[0031] The notch 102 is formed at the bottom of the top box 101, the top box 101 is glued and fixed to the upper surface of the sticker 201, and the notch 102 is aligned with the area where the label coating 202 is located;
[0032] The horizontal slide 103 is provided at the front and rear ends of the outer wall of the top box 101. The horizontal slide 103 is symmetrically arranged with two sets of horizontal slides 103 around the center line of the top box 101. The fixed triangular tooth 104 is integrally formed at the bottom of the inner wall of the top box 101 and extends to the top of the inner wall of the horizontal slide 103. The anti-transfer component 3 is distributed on the inner side of the top box 101 and the horizontal slide 103.
[0033] The anti-transfer component 3 includes a horizontal push plate 301, an elastic triangular locking tooth 302, and a V-shaped spring 303;
[0034] The horizontal push plate 301 is symmetrically slidably connected to the inner side of two sets of horizontal slide grooves 103, and the elastic triangular tooth 302 is fixed to the top of the horizontal push plate 301 and is in a one-way locking state with the fixed triangular tooth 104.
[0035] V-shaped spring clips 303 are distributed inside the sticker 201 and fixed in the middle of the two horizontal push plates 301. The bottom of the V-shaped spring clips 303 is close to the top of the notch 102.
[0036] By bringing two horizontal push plates 301 close to each other, the V-shaped spring 303 is deformed and its bottom passes through the notch 102 and contacts the upper surface of the sticker 201. When the sticker 201 is peeled off, the V-shaped spring 303 punctures the sticker 201.
[0037] In this embodiment, it should be noted that the tag coating 202 includes a chip and an antenna. When this RFID asset management tag leaves the factory, the two horizontal push plates 301 are at their furthest distance from each other. At this time, the bottom of the V-shaped spring 303 does not contact the sticker 201, thus ensuring the normal use of the RFID tag 2. Its usage method is as follows:
[0038] First, remove the release paper from the adhesive layer 203. Then, use the adhesive layer 203 to bond and fix the entire label to the designated position. At this time, the label coating 202 is attached to the object surface but not bonded. It can then be used normally (the RFID tag 2 uses the same principle as the passive RFID tags on the market, which will not be described in detail here).
[0039] After bonding is completed, manually press and push the two horizontal push plates 302 towards the middle. The two horizontal push plates 302 press the V-shaped spring sheet 302 to bend further around the middle crease. The bottom horizontal height of the V-shaped spring sheet 302 decreases and passes through the notch 102 to adhere to the upper surface of the sticker 201. Then, the horizontal push plates 302 move closer and the two side plates of the V-shaped spring sheet 302 bend further, so that the bottom of the V-shaped spring sheet 302 has greater pressure on the sticker 201. (It should be noted that the two side plates of the V-shaped spring sheet 302 have a certain curvature in the initial state. When the sticker 201 is pressed by the bottom of the V-shaped spring sheet 302, the lower surface of the V-shaped spring sheet 302 contacts the surface of the object. Therefore, the sticker 201 will not be broken by the V-shaped spring sheet 302 at this time.)
[0040] It should also be noted that during the horizontal movement of the horizontal push plate 302, the inclined surface of the elastic triangular tooth 302 is pressed against the inclined surface of the fixed triangular tooth 104, and the elastic triangular tooth 302 is deformed under force. When the elastic triangular tooth 302 is located between the two fixed triangular teeth 104, the elastic triangular tooth 302 is reset under the action of its own material elasticity, and its vertical surface is in contact with the vertical surface of the fixed triangular tooth 104, thus achieving a one-way locking effect.
[0041] When the RFID tag 2 is peeled off, the sticker 201 separates from the object along with the top box 101. No residue is left on the adhesive layer 203. At the same time, when the middle part of the sticker 201 (i.e., the area where the tag coating 202 is located) separates from the object surface, the elastic potential energy generated by the compression of the V-shaped spring 302 is released. The V-shaped spring 302 will press down on the middle part of the sticker 201, causing the middle part of the sticker 201 to tear. The tag coating 202 is simultaneously destroyed and broken, thereby achieving the anti-transfer effect. At the same time, no residue is left on the object surface, avoiding the need for subsequent cleaning of residual adhesive.
[0042] Please refer to this carefully. Figures 1-4 The sticker 201 is aligned with the bottom of the V-shaped spring 303 with an easy-tear dotted line 204, which does not come into contact with the label coating 202.
[0043] In this embodiment: by means of the easy-tear dotted line 204, when the V-shaped spring 302 presses down on the middle of the sticker 201, the sticker 201 can be torn along the easy-tear dotted line 204, thus ensuring the stable execution of the anti-transfer effect.
[0044] Please refer to this carefully. Figures 3-4 The V-shaped spring 303 has multiple evenly distributed straight slots 304 along the longitudinal direction.
[0045] In this embodiment: the straight groove 304 structure divides the contact area between the V-shaped spring 303 and the sticker 201 into multiple parts, thereby achieving independent compression and tearing of multiple positions of the sticker 201, further ensuring the tearing effect.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
