Description

Technical Field

[0001] The invention relates to a sealed anti-disassembly radio frequency tag and an installation method, belonging to the technical field of radio frequency tags. Background Art

[0002] As a passive IoT identification technology, RFID has been applied in more and more scenarios, and in many application scenarios, the anti-tear and anti-counterfeiting functions of RFID technology are needed. For conventional antennas, the usual practice is to glue all or part of the RFID tag antenna to the opening of the object with glue. When the opening is opened, the tag antenna is destroyed, thereby rendering the entire tag invalid and achieving the anti-tear and anti-counterfeiting function; in addition, for chips with detection functions, the usual practice is to glue the detection line to the opening of the object with glue. When the detection line is destroyed, the chip will record the status inside, thereby achieving the anti-tear and anti-counterfeiting function. The above anti-tear and anti-counterfeiting solutions are all attached to the outside of the object. By heating, soaking in medicine, etc., the label can be separated from the object without destroying the label. Therefore, both of the above solutions have certain risks or loopholes, and the anti-tear and anti-counterfeiting effects are difficult to guarantee. Summary of the invention

[0018] The specific implementation modes of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] The present invention designs a sealed anti-tampering radio frequency tag, which is arranged on a box body 2 with an opening 1. In practical applications, Figure 1 , 2 , 4, comprising a radio frequency chip 3, a carrier substrate 4, a first double-sided adhesive tape 5, and a second double-sided adhesive tape 6, wherein the radio frequency chip 3 is arranged on the surface of the carrier substrate 4, and the port of the radio frequency chip 3 is connected to the wiring arranged on the surface of the carrier substrate 4, and the wiring forms a radio frequency radiation structure 7 on the surface of one end of the carrier substrate 4, and a detection structure 8 on the surface of the other end of the carrier substrate 4, and the radio frequency chip 3 is not located in the area where the detection structure 8 is located on the carrier substrate 4; one side of the first double-sided adhesive tape 5 is pasted on the back of the position where the radio frequency radiation structure 7 is set on the carrier substrate 4, and one side of the second double-sided adhesive tape 6 is pasted on the surface of the carrier substrate 4 in a manner of covering the detection structure 8; based on the opening cover 1 being set at the opening position on the box body 2, the other side of the first double-sided adhesive tape 5 is pasted on the inner surface of the box body 2, and the other side of the second double-sided adhesive tape 6 is pasted on the inner surface of the opening cover 1, and the overall surface tension F2 of the detection structure 8 and the local section of the carrier substrate 4 where it is set is less than the adhesion F3 between the second double-sided adhesive tape 6 and the inner surface of the opening cover 1. In application, the supporting substrate can be paper, PET, PI, etc. In actual application, the first double-sided tape 5 can be pasted on any position of the inner surface of the box body 2, as long as the second double-sided tape 6 is pasted on the inner surface of the cover 1, and the overall surface tension F2 of the detection structure 8 and the local section of the supporting substrate 4 on which it is provided is less than the adhesion F3 between the second double-sided tape 6 and the inner surface of the cover 1.

[0020] Regarding the specific implementation of the radio frequency radiation structure 7 and the detection structure 8, Figure 1 , 2 As shown in , 4, based on the RF chip 3 being arranged on the surface of the carrier substrate 4, the port of the RF chip 3 is connected to the routing arranged on the same surface of the carrier substrate 4, and the routing forms a RF radiation structure 7 on the surface of the RF chip 3 at one end of the carrier substrate 4, and a detection structure 8 on the surface of the RF chip 3 at the other end of the carrier substrate 4, and the RF chip 3 is not located in the area where the detection structure 8 is located on the carrier substrate 4.

[0021] In practical applications, the working frequency bands of the radio frequency radiation structure 7 and the radio frequency chip 3 involved in the present invention can be the frequency band range specified in the RFID field such as low frequency, high frequency, and ultra-high frequency. The existing radio frequency chip 3 is divided into a radio frequency chip with a detection function and a radio frequency chip without a detection function. Among them, if the radio frequency chip 3 is a radio frequency chip with a detection function, then Figure 1 As shown, the RF port of the RF chip 3 is connected to the first routing line arranged on the surface of the carrier substrate 4, and the first routing line forms a RF radiation structure 7 on the surface of one end of the carrier substrate 4, and the detection port of the RF chip 3 is connected to the second routing line arranged on the surface of the carrier substrate 4, and the second routing line forms a detection structure 8 on the surface of the other end of the carrier substrate 4; if the RF chip 3 is a RF chip without a detection function, then Figure 4 As shown, the RF port of the RF chip 3 is connected to the third routing line arranged on the surface of the carrier substrate 4. The third routing line is first wired to the surface of one end of the carrier substrate 4 to form a RF radiation structure 7, and then wired to the surface of the other end of the carrier substrate 4 to form a detection structure 8.

[0022] The above-mentioned design of sealed anti-tampering radio frequency tag technical solution is further applied in practical applications, such as Figure 3 As shown, the box body 2 with the opening cover 1 is specifically designed to include a cover plate 1-1, and a hanging edge 1-2 connected to one side of the cover plate 1-1. When the opening position of the box body 2 is set based on the opening cover 1, the inner side of the hanging edge 1-2 faces the outer side of the box body 2, and the side corresponding to the position of the hanging edge 1-2 on the opening edge of the box body 2 is defined as the target side. Based on the design of the box body 2 and the opening cover 1 of such a structure, on the basis of the other side of the first double-sided adhesive 5 being pasted on the inner surface of the box body 2, the supporting substrate 4 faces the target side with the back side of the position where the second double-sided adhesive 6 is set, and is folded along the target side position toward the outer side of the box body 2 opening, so that the second double-sided adhesive 6 is partially attached to the supporting substrate 4 where it is set. The segment is hung on the target edge of the opening of the box body 2, and the other side of the second double-sided adhesive 6 faces away from the outer side of the box body 2. The supporting substrate 4 and the second double-sided adhesive 6 are hung on the target edge of the opening of the box body 2 here, but it is necessary to ensure that the covering of the opening of the box body 2 by the opening cover 1 is not affected. Therefore, based on this hanging structure design, based on the opening cover 1 being covered at the opening position of the box body 2, the other side of the second double-sided adhesive 6 is adhered to the inner side surface of the hanging edge 1-2, and along the projection direction perpendicular to the surface of the hanging edge 1-2, the projection of the second double-sided adhesive 6 is located within the projection of the hanging edge 1-2, and the overall surface tension F2 of the detection structure 8 and the local segment of the supporting substrate 4 set thereon is less than the adhesion F3 between the second double-sided adhesive 6 and the inner side surface of the hanging edge 1-2.

[0023] Under the above-mentioned design of the opening cover 1 with the hanging edge 1-2, a gasket 9 is further designed to be added, such as Figure 5As shown, based on the second double-sided adhesive tape 6 being hung on the target edge of the opening of the box body 2 along with the partial segment of the supporting substrate 4, the gasket 9 is arranged on the outer surface of the box body 2 at a position corresponding to the partial segment of the supporting substrate 4, that is, for the partial segment of the supporting substrate 4 hung on the target edge of the opening of the box body 2, a gasket 9 is added at a position facing the outer side surface of the box body 2. The gasket 9 can be flexible or hard, and its function is to provide a supporting force for the hanging edge 1-2 when combined with the second double-sided adhesive tape 6, thereby increasing the reliability of adhesion between the hanging edge 1-2 and the second double-sided adhesive tape 6.

[0024] And in the structural design between the second double-sided adhesive tape 6 and the detection structure 8, as Figure 1 , 4 As shown, a flower cut line 10 is further designed and arranged on the surface of the supporting substrate 4 in the area where the detection structure 8 is located, and the flower cut line 10 cuts through the surface position of the supporting substrate 4 where it is arranged, and the position where it is arranged corresponds to the position on the surface of the second double-sided adhesive tape 6. Through the arrangement of the flower cut line 10, the overall surface tension F2 of the detection structure 8 and the local section of the supporting substrate 4 where it is arranged is further made smaller than the adhesive force F3 between the second double-sided adhesive tape 6 and the inner side of the opening cover 1, that is, in the process of opening the opening cover 1, the detection structure 8 is more easily destroyed, so that the anti-dismantling detection of the designed radio frequency tag in actual application is more sensitive.

[0025] In actual applications, the detection structure 8 is further designed to be a non-closed ring structure arranged by routing on the surface of the supporting substrate 4 where it is set, and based on this, the flower knife line 10 is designed to be set in the ring structure of the detection structure 8 on the surface of the supporting substrate 4. The flower knife line 10 is connected to reduce the overall surface tension F2 of the detection structure 8 and the local section of the supporting substrate 4 where it is set. The detection structure 8 surrounds the flower knife line 10, and the effect brought by the flower knife line 10 is evenly dispersed on the structure of the detection structure 8 around it, thereby further improving the sensitivity of the detection structure 8 to being destroyed in actual applications.

[0026] On the basis of the above design, in actual application, a release paper 11 is further designed to be added, one surface of the release paper 11 is pasted on the other surface of the second double-sided adhesive 6, and the adhesive force F1 between the release paper 11 and the second double-sided adhesive 6 is less than the overall surface tension F2 of the detection structure 8 and the partial section of the supporting substrate 4 provided thereon; for the opening cover 1 composed of the cover plate 1-1 and the hanging edge 1-2 connected to one side thereof, based on the fact that the other side of the first double-sided adhesive 5 is pasted on the inner surface of the box body 2, the second double-sided adhesive 6 is hung on the target edge of the opening of the box body 2 along the partial section of the supporting substrate 4 provided thereon, and the other side of the second double-sided adhesive 6 faces away from the outer side surface of the box body 2, and the position on the edge of the second double-sided adhesive 6 closest to the target edge of the opening of the box body 2 is defined as the reference position, and the length of the surface of the hanging edge 1-2 along the direction perpendicular to the target edge of the opening of the box body 2 is a, and the length of the surface of the release paper 11 from the position corresponding to the reference position on the second double-sided adhesive 6 along the direction perpendicular to the target edge of the opening of the box body 2 and away from the center of the second double-sided adhesive 6 is greater than a, that is, according to Figure 3 , 4 As shown, when the second double-sided adhesive tape 6 is hung on the target edge of the opening of the box body 2 along with the partial section of the supporting substrate 4, the bottom edge of the release paper 11 extends downward beyond the lower edge of the hanging edge 1-2, that is, when the opening cover 1 is covered at the opening position of the box body 2 and the hanging edge 1-2 covers the outer surface of the release paper 11, it is convenient to pull out the release paper 11 and make the other side of the second double-sided adhesive tape 6 stick to the inner side surface of the hanging edge 1-2.

[0027] In conjunction with the application of the release paper 11, the design requires that the adhesive force F1 between the release paper 11 and the second double-sided adhesive tape 6 < the overall surface tension F2 of the detection structure 8 and the local section of the supporting substrate 4 on which it is provided < the adhesive force F3 between the second double-sided adhesive tape 6 and the inner side of the opening cover 1, that is, in the actual application, in the process of designing the installation of the radio frequency tag, ensure that in the process of separating the release paper 11 from the second double-sided adhesive tape 6, the overall structure of the detection structure 8 and the local section of the supporting substrate 4 on which it is provided will not be destroyed in advance, and in connection with the opening force F4 for the opening cover 1 in actual application, that is, in actual product design application, it is required that F1 <F2<F3<F4。

[0028] Considering the addition of the release paper 11 here, the flower knife line 10 needs to cut through the surface position of the supporting substrate 4 where it is set, and the position where it is set corresponds to the surface of the second double-sided adhesive 6, but it cannot cut the release paper 11. There needs to be a certain space between the edge of the flower knife line 10 and the wiring of the detection structure 8 to avoid tearing the wiring of the detection structure 8 in advance during the closing process of the cover 1. Therefore, the role of the flower knife line 10 is to modify the structure of the radio frequency tag in advance, so that the tension F2 of the tag itself within the wiring range of the detection structure 8 is less than the adhesion force F3 between the second double-sided adhesive area and the inner surface of the cover 1, so as to ensure that the wiring of the detection structure 8 can be torn off when the cover 1 is opened, thereby achieving the effect of destroying the tag and realizing detection.

[0029] Similarly, in practical applications, the pattern cut lines 10 are not limited to being located within the wiring structure of the carrier substrate 4. The pattern cut lines 10 can also be designed to be placed on the periphery of the wiring structure of the carrier substrate 4, and the number and style of the pattern cut lines 10 are not fixed, as long as the tension F2 of the label itself within the wiring range of the detection structure 8 is smaller than the adhesion F3 between the second double-sided adhesive area and the inner surface of the cover 1.

[0030] In practical applications, for the RF chip 3 with a detection function, the detection structure 8 and the RF radiation structure 7 are independent of each other. After the detection structure 8 is destroyed, it is only recorded inside the RF chip 3 without affecting the characteristics of the RF radiation structure 7. For the RF chip 3 without a detection function, a part of the RF radiation structure 7 can be made to form a detection structure 8 in a ring area, as shown in FIG. Figure 4 As shown, the outermost routing coil is led out at a suitable position, and forms a non-closed detection area, namely the detection structure 8, after passing through the extension section, and then returns to the outermost side of the RF radiation structure 7, so that the RF radiation structure 7 is still a complete closed loop with normal functions.

[0031] In practical application, in conjunction with the structure of the radio frequency tag designed above, the present invention further designs an installation method, which is used in practical application to perform anti-disassembly detection on the installed box 2 by the designed radio frequency tag. Figure 6 As shown, the installation method is performed according to the following steps A to D to implement the installation method of the sealed anti-tampering radio frequency tag on the box body 2 with the open cover 1.

[0032] Step A. Open the cover 1 and put the items to be protected into the box 2. The other side of the first double-sided adhesive tape 5 is adhered to the inner surface of the box 2. The back side of the supporting substrate 4 where the second double-sided adhesive tape 6 is set faces the target edge, and is folded along the target edge toward the outer side of the opening of the box 2, so that the second double-sided adhesive tape 6 is hung on the target edge of the opening of the box 2 along with the partial section of the supporting substrate 4 where it is set, and the other side of the second double-sided adhesive tape 6 faces away from the outer side of the box 2.

[0033] Step B. Based on a straight line position on the surface of the release paper 11 that passes through a position corresponding to a reference position on the second double-sided adhesive tape 6 and is parallel to the target edge, a target local segment on the surface of the release paper 11 starting from the straight line position along a direction perpendicular to the target edge of the opening of the box body 2 and away from the center of the second double-sided adhesive tape 6 is folded outward with the straight line position as the folding position, and is in surface contact with the local segment of the release paper 11 adhered to the second double-sided adhesive tape 6.

[0034] Step C. The cover 1 is placed at the opening of the box 2 so that the inner side of the hanging edge 1 - 2 faces and presses the release paper 11 , and the end of the target partial section of the release paper 11 farthest from its folding position is exposed to the outer space of the box 2 .

[0035] Step D. Pull the end of the target partial section of the release paper 11 that is farthest from the folded position toward the external space of the box body 2, and then separate the entire release paper 11 from the second double-sided adhesive tape 6, and then the other side of the second double-sided adhesive tape 6 is adhered to the inner side surface of the hanging edge 1-2, completing the installation of the sealed anti-tampering RFID tag on the box body 2.

[0036] The installed RFID tag has normal working performance; once the cover 1 is opened, due to the presence of the patterned cut line 10, it ensures that the overall surface tension F2 of the detection structure 8 and the local section of the supporting substrate 4 on which it is provided is less than the adhesion force F3 between the second double-sided adhesive 6 and the inner side of the cover 1 and less than the opening force F4 of the cover 1. Therefore, during the opening process of the cover 1, the non-closed ring structure of the detection structure 8 is broken, and the change of the RFID tag performance or the change of the internal data of the RFID chip 3 can be detected, that is, it is detected that the box body 2 is opened.

[0037] The present invention designs a carrier substrate 4 equipped with a radio frequency radiation structure 7 and a detection structure 8, and adheres a first double-sided adhesive tape 5 to the back side of the position where the radio frequency radiation structure 7 is set on the carrier substrate 4, and adheres a second double-sided adhesive tape 6 to the surface of the carrier substrate 4 in a manner of covering the detection structure 8. The corresponding designed installation method is applied to a box body 2 with an opening cover 1, and the first double-sided adhesive tape 5 is adhered to the inner surface of the box body 2, and the second double-sided adhesive tape 6 is adhered to the inner surface of the opening cover 1. During the application, whether the opening cover 1 is opened can be determined by detecting whether the structure 8 is damaged, thereby realizing the sealing and anti-disassembly function of the box body 2. The invention has the characteristics of simple operation, high concealment, and obvious destructive effect, and realizes an efficient sealing and anti-disassembly effect on the protected items.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
