Description

Technical Field

[0001] The utility model relates to the technical field of RFID tags, in particular to an RFID tag with anti-transfer and non-residual glue characteristics. Background Art

[0002] An electronic tag, also known as a radio frequency tag, transponder, or data carrier, is a device that stores data identification information and can transmit information to and from a reader through radio waves to respond with identification information to the reader. It is divided into two types: active RFID tags and passive RFID tags.

[0003] Among them, a passive RFID tag does not contain a battery, and its electrical energy is obtained from an RFID reader. When the passive RFID tag approaches the RFID reader, the antenna of the passive RFID tag converts the received electromagnetic wave energy into electrical energy, activates the chip in the RFID tag, and sends out the data in the RFID chip. It has the advantages of small size, light weight, low cost, long lifespan (with a lifespan guarantee of more than 10 years), maintenance-free, and can be made into different shapes such as thin sheets or hanging buckles for application in different environments.

[0004] Existing passive RFID tags have been widely used in jewelry management. When in use, they are generally tied to jewelry products by means of cable ties. However, when the cable tie is tied to the jewelry product, the inner side size of the cable tie is larger than the outer diameter of the jewelry product, and there is a relatively loose state between the cable tie and the jewelry product, and the cable tie has a certain amount of movement space. When encountering a ring-shaped jewelry with an opening, the cable tie can move along the trajectory of the ring-shaped jewelry and detach from the opening, thus causing the RFID tag to lose its anti-transfer function.

[0005] If the passive RFID tag is directly pasted on a ring-shaped jewelry with an opening using glue, it is easy to leave residual glue when removing the passive RFID tag, which then requires secondary cleaning. This is not only troublesome but also likely to cause damage to the jewelry product during the cleaning process. Based on this, an RFID tag with anti-transfer and non-residual glue characteristics is provided. Summary of the Invention

[0006] The purpose of the utility model is to provide an RFID tag with anti-transfer and non-residual glue characteristics to solve the problems in the above background.

[0007] To achieve the above object, the present utility model provides the following technical solutions: An anti-transfer and non-residual glue RFID tag, including an RFID tag with a tag body and a cable tie. The surface of the tag body is printed with a loop antenna, an IC chip, and a chip capacitor. The cable tie is used to tie onto a jewelry product. The cable tie is composed of a connecting strip and a binding strip. The binding strip is integrally formed at the top end of the connecting strip. A superimposing notch penetrating through both end faces of the connecting strip is opened at the bottom end of the connecting strip. The inner wall width of the superimposing notch matches the width of the binding strip;

[0008] A first adhesive layer is coated on the surface of the tag body. The connecting strip is adhesively fixed to the surface of the tag body through the first adhesive layer. The binding strip passes through the jewelry product and is bent to fit against the inner side of the superimposing notch. The tag body is folded to wrap and fix the ends of the connecting strip and the binding strip through the first adhesive layer;

[0009] The RFID tag further includes a contraction unit and a fixing unit;

[0010] The contraction unit is used to perform a tightening operation on the loop area formed by the bending of the binding strip to achieve a tight fit between the binding strip and the jewelry product;

[0011] The fixing unit is used to fix the position of the contraction unit.

[0012] As a further scheme of the present utility model: The contraction unit includes a T-shaped hem, a second adhesive layer, and a third adhesive layer;

[0013] The T-shaped hem is fixed to the top end of the tag body. The second adhesive layer is coated on half of the vertical side of the T-shaped hem. The third adhesive layer is coated on one side of the horizontal side of the T-shaped hem, and there is a gap between the third adhesive layer and the second adhesive layer;

[0014] When the connecting strip is adhesively bonded to the tag body, the binding strip is aligned with the side of the T-shaped hem where the third adhesive layer is not coated. The T-shaped hem is folded to wrap the bent binding strip in the middle through the second adhesive layer and the third adhesive layer. The tightening of the loop area formed by the bending of the binding strip can be achieved by moving the wrapping circle formed by the folding of the horizontal side of the T-shaped hem.

[0015] As a further scheme of the present utility model: The fixing unit includes a fixing backing paper, a fixing hem, and a fourth adhesive layer;

[0016] The fixing backing paper is fixed to the bottom of the horizontal side of the T-shaped hem and is aligned with the binding strip. The fixing hem is fixed to one side of the fixing backing paper. The fourth adhesive layer is coated on the surface of the fixing hem. When the fixing hem is folded and aligned with the fixing backing paper, it is adhesively fixed through the fourth adhesive layer to achieve the relative position fixation between the T-shaped hem and the connecting strip.

[0017] As a further solution of the utility model: Chamfered notches are formed on both sides of the connection between the T-shaped folded edge and the label body, so as to facilitate tearing and disconnection between the T-shaped folded edge and the label body.

[0018] As a further solution of the utility model: The label body, the T-shaped folded edge, the fixed back paper, the fixed folded edge, and the chamfered notches are integrally formed by die-cutting process, and the tie strap is integrally formed by die-cutting process.

[0019] As a further solution of the utility model: The folding center line of the label body and the T-shaped folded edge are aligned, and the gap width between the third adhesive layer and the second adhesive layer is greater than the width of the binding strip.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] By providing a contraction unit and a fixing unit, the binding strip is kept in close contact with the surface of the annular jewelry, so that the binding strip is not easy to move on the surface of the annular jewelry, thus ensuring the anti-disassembly and transfer function of the RFID tag, and there is no adhesive connection between the whole RFID tag and the annular jewelry, avoiding the situation of residual glue after disassembly.

The cable tie 2 is composed of a connecting strip 201 and a binding strip 202. The binding strip 202 is integrally formed at the top end of the connecting strip 201. A superposition notch 203 that penetrates both end faces of the connecting strip 201 is opened at the bottom end of the connecting strip 201. The inner wall width of the superposition notch 203 matches the width of the binding strip 202;

[0027] A first adhesive layer 105 is coated on the surface of the tag body 101. The connecting strip 201 is adhesively fixed to the surface of the tag body 101 through the first adhesive layer 105. The binding strip 202 passes through the jewelry product and is bent to fit inside the superposition notch 203. The tag body 101 is folded to wrap and fix the ends of the connecting strip 201 and the binding strip 202 through the first adhesive layer 105;

[0028] The RFID tag 1 further includes a contraction unit and a fixing unit. The contraction unit is used to perform a tightening operation on the annular area formed by the bending of the binding strip 202 to achieve close fitting between the binding strip 202 and the jewelry product. The fixing unit is used to fix the position of the contraction unit;

[0029] The contraction unit includes a T-shaped hem 102, a second adhesive layer 106, and a third adhesive layer 107;

[0030] The T-shaped hem 102 is fixed to the top end of the tag body 101. The second adhesive layer 106 is coated on half of the vertical side of the T-shaped hem 102. The third adhesive layer 107 is coated on one side of the horizontal side of the T-shaped hem 102, and there is a gap between the third adhesive layer 107 and the second adhesive layer 106. When the connecting strip 201 is adhesively connected to the tag body 101, the binding strip 202 is aligned with the side of the T-shaped hem 102 where the third adhesive layer 107 is not coated. The T-shaped hem 102 can wrap the bent binding strip 202 in the middle through the second adhesive layer 106 and the third adhesive layer 107. The tightening of the annular area formed by the bending of the binding strip 202 can be achieved by moving the wrapping circle formed by the folding of the horizontal side of the T-shaped hem 102;

[0031] The fixing unit includes a fixing backing paper 103, a fixing hem 104, and a fourth adhesive layer 108;

[0032] The fixing backing paper 103 is fixed to the bottom of the horizontal side of the T-shaped hem 102 and is aligned with the binding strip 202. The fixing hem 104 is fixed to one side of the fixing backing paper 103. The fourth adhesive layer 108 is coated on the surface of the fixing hem 104. When the fixing hem 104 is folded and aligned with the fixing backing paper 103, it is adhesively fixed through the fourth adhesive layer 108 to achieve the relative position fixing between the T-shaped hem 102 and the connecting strip 201;

[0033] On both sides of the connection between the T-shaped hem 102 and the label body 101, inclined notches are formed to facilitate tearing and disconnection between the T-shaped hem 102 and the label body 101.

[0034] The folding midline of the label body 101 is aligned with the T-shaped hem 102, and the gap width between the third adhesive layer 107 and the second adhesive layer 106 is greater than the width of the binding strip 202.

[0035] In this embodiment, it should be noted that the surfaces of the first adhesive layer 105, the second adhesive layer 106, the third adhesive layer 107, and the fourth adhesive layer 108 are all covered and protected by release paper.

[0036] When using this RFID tag 1 to manage and mark a ring-shaped jewelry with an opening, the operation steps are as follows:

[0037] First, tear off the release paper on the first adhesive layer 105, and then paste the connecting strip 201 on the first adhesive layer 105. At this time, the position of the binding strip 202 is aligned with the side of the fixed backing paper 103 and the T-shaped hem 102 without adhesive.

[0038] Then, pass the binding strip 202 through the area where the ring-shaped jewelry is located, bend it to wrap the ring-shaped jewelry, then insert the end of the binding strip 202 into the inner side of the overlapping notch 203 and bond it to the first adhesive layer 105 for fixation. Then, fold the label body 101 in half, and the folded label body 101 is bonded and fixed through the first adhesive layer 105, while covering and fixing the ends of the binding strip 202 and the connecting strip 201.

[0039] Then, tear off the release paper on the second adhesive layer 106 and the third adhesive layer 107, and fold the T-shaped hem 102 in half. At this time, the folded T-shaped hem 102 is bonded and fixed through the second adhesive layer 106 and the third adhesive layer 107, while forming a wrap around the bent area of the binding strip 202.

[0040] Then, tear open the connection between the T-shaped hem 102 and the label body 101 to separate the T-shaped hem 102 from the label body 101. Then, push the T-shaped hem 102 towards the ring-shaped jewelry. At this time, the T-shaped hem 102 tightens the ring-shaped area formed by the bending of the binding strip 202.

[0041] When the lashing strip 202 is in close fit with the annular jewelry, the release paper on the fourth adhesive layer 108 is removed, and the fixed folding edge 104 is folded to align with the fixed back paper 103, and the lashing strip 202 is located in the middle of the fixed folding edge 104 and the fixed back paper 103. At this time, the fixed folding edge 104 is fixed to the lashing strip 202 and the fixed back paper 103 through the fourth adhesive layer, and then the position of the T-shaped folding edge 102 and the lashing strip 202 is fixed, so that the tightened state of the lashing strip 202 is maintained stable;

[0042] Through the cooperation of the above-mentioned multiple parts, the lashing strip 202 is kept in close fit with the surface of the annular jewelry, so that the lashing strip 202 is not easy to move on the surface of the annular jewelry (it should be added that there are some raised decorations on the surface of the annular jewelry, and these raised decorations can also limit the movement of the lashing strip 202). Thus, the anti-disassembly and transfer function of the RFID tag is ensured, and there is no adhesive connection between the whole RFID tag and the annular jewelry, avoiding the situation of residual adhesive after disassembly.

[0043] Please refer specifically to Figures 1 to 2 , the label body 101, the T-shaped folding edge 102, the fixed back paper 103, the fixed folding edge 104, and the inclined slot are integrally formed by die-cutting process, and the tie strap 2 is integrally formed by die-cutting process.

[0044] In this embodiment: Through this structure, the processing and production process of the whole tag is simple, which is convenient to improve the production on the basis of the existing RFID tag production process, and is convenient for popularization and production.

[0045] The above is only the 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 and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
