[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0026] First, a brief description of the technical solution of the present utility model is given. For example, Figures 1 to 2 As shown, an anti-metal radio frequency identification electronic tag with anti-transfer function provided by the present utility model includes: an anti-metal layer 100, an adhesive layer 200, an antenna layer 300, a substrate layer 400, a bridge layer 500, a bridge conduction point 600, and a chip 700. The antenna layer 300 includes an antenna body 301 and a detection line 302. As Figure 3 shown, the substrate layer 400 includes: a first substrate layer 401, a second substrate layer 402, and a third substrate layer 403.

[0027] The antenna layer 300 includes a detection line 302 and an antenna body 301. The detection line 302 is provided on or embedded in the antenna layer 300. Further, the part of the antenna layer 300 where the antenna body 301 is located corresponds to the part of the first substrate layer 401 of the substrate layer 400, the part of the antenna layer 300 where part of the detection line 302 and all the scissor marks 800 are located corresponds to the part of the second substrate layer 402 of the substrate layer 400, and the part of the antenna layer 300 where the remaining part of the detection line 302 is located corresponds to the part of the third substrate layer 403 of the substrate layer 400.

[0028] One group of pins of the chip 700 is used to connect to the antenna body 301, and the other group of pins is used to connect to the detection line 302. As Figure 4 shown, there are four pins 1100 for the chip 700 to connect to the antenna. Among them, pins 1103 and 1104 connect the chip 700 and the detection line 302 to form a first antenna loop, and pins 1101 and 1102 connect the chip 700 and the antenna body 301 to form a second antenna loop. Among them, the chip 700 does not contact any part of the detection line 302 except for the pins, and the antenna body 301 has an anti-metal layer 100.

[0029] The bridge conduction point 600 is a metal connection element. As Figure 1 shown, it penetrates through the substrate layer 400 (the first substrate layer 401) and the antenna layer 300. The bridge conduction point 600 is connected to the chip 700 provided in the antenna body 301, and each bridge conduction point 600 is connected through the bridge layer 500, thereby forming a second antenna loop composed of the chip 700 - antenna body 301 - bridge layer 500 - bridge conduction point 600 - chip 700.

[0030] Among them, there are 2 bridge conduction points 600 provided on the antenna body 301. The two bridge conduction points 600 form an antenna path through the bridge layer 500 and the chip in the antenna layer 300. Among them, the bridge layer 500 is a connecting line for connecting the bridge conduction points 600.

[0031] On the second substrate layer 402 of the substrate layer 400, there are scoring lines 800. When the label is torn by an external force, the scoring lines 800 on the substrate layer 400 start to disintegrate, causing the detection line 302 to break or break and separate from the antenna layer 300 simultaneously. At this time, the first antenna circuit is disconnected, and the second antenna circuit remains connected.

[0032] Among them, the detection line 302 is in an irregular shape, square, rectangular, or any one of the shapes with a wider upper part and a narrower lower part or a narrower upper part and a wider lower part.

[0033] As Figure 1 shown, the adhesive layer 200 is coated on the outer surface of the antenna body 301, and the metal-resistant layer 100 is coated on the adhesive layer 200. The metal-resistant layer 100 is composed of two sides, namely a metal-resistant surface and an attachment surface, which are bonded together (not shown in the figure). The attachment surface is a PET attachment surface (polyethylene terephthalate) or a paper attachment surface.

[0034] Among them, when the attachment surface is a PET attachment surface, the area of the metal-resistant layer 100 is the same as the area of the antenna body 301, specifically as the shaded part shown in Figure 2 shown.

[0035] In actual use, in order to ensure the easy-to-tear performance of the label, referring to Figure 1 , when the label is set on a commodity (preferably pasted on the commodity through the adhesive layer 1100), the adhesive layer 1100 at the outer layer position of the metal-resistant layer 100 corresponding to the first substrate layer 401 and the third substrate layer 403 uses a strong adhesive, and the adhesive layer 1100 at the corresponding position of the second substrate layer 402 uses a common glue.

[0036] In order to better achieve the purpose of "easy to tear" in the present invention, as shown in Figure 7 and Figure 8 shown, the attachment surface of the metal-resistant layer 100 of the label can be a paper attachment surface (using a fragile paper substrate). If a fragile paper substrate attachment surface is selected, the metal-resistant layer 100 covers the entire label, and the adhesive layer 1100 completely covers the metal-resistant layer 100. In order to further meet the easy-to-tear property, the weight of the fragile paper substrate is between 30 and 70 grams.

[0037] In the technical solution of the present invention, the metal surface of the metal-resistant layer 100 is a ferrite material, an iron-silicon-aluminum material, or an alloy powder coating (at least one of iron-nickel alloy flake powder, iron-cobalt alloy flake powder, iron-silicon-aluminum alloy flake powder, or hydroxy iron flake powder).

[0038] Now, the technical solution of the present invention will be described in detail:

[0039] Only for the label:

[0040] For the antenna layer 300 and the chip 700 therein:

[0041] The chip 700 is disposed between the antenna body 301 and the detection line 302. At the same time, the bottoms of the two bridge conduction points 600 are both set inside the antenna body 301. Further, as Figure 1 shown, a substrate layer 400 is covered on the antenna layer 300, and the bridge conduction points 600 pass through the substrate layer 400 and are exposed outside. The parts of the two bridge conduction points 600 exposed outside the substrate layer 400 are covered by the bridge layer 500.

[0042] The outer layer of the antenna body 301 is covered with an adhesive layer 200, and an anti-metal layer 100 is disposed outside the adhesive layer 200, which is used to reduce the interference of metal on the radio frequency signal, so as to ensure that the communication distance and reading performance remain available when applied on the metal surface.

[0043] Based on the above structure, the chip 700 in the antenna layer 300 forms a loop by means of the bridge layer 500 and the bridge conduction points 600. The antenna layer 300 can be prepared by an aluminum etching or silver paste printing process. In particular, the bridge layer 500 and the antenna layer 300 can be symmetrically disposed on both sides of the substrate layer 400 ( Figure 1 ), or, the bridge layer 500 and the antenna layer 300 are located on the same side of the substrate layer 400. When the bridge layer 500 and the antenna layer 300 are located on the same side of the substrate layer 400, an isolation layer is added: the bridge layer 500, the isolation layer, the antenna 300, the substrate 400, the adhesive layer 200, and the anti-metal layer 100 are arranged in sequence. Among them, the isolation layer is an insulating layer for isolating the bridge layer 500 and the antenna layer 300 (the area of the insulating layer only covers the bridge layer 500 and the conduction points 600 connected to the bridge layer 500).

[0044] Select according to the actual preparation process: when using the silver paste printing process for preparation, the bridge layer 500 can be on the same side of the substrate as the antenna. The anti-metal layer 100 covers the main antenna part (antenna body 301) to form the radio frequency identification ability on the metal surface.

[0045] Regarding the detection line 302:

[0046] The antenna layer 300 of the antenna body 301 and the antenna layer 300 of the detection line 302 are integrated. There are scoring lines 800 at the position corresponding to the detection line 302 on the substrate 400. The detection line 302 is outside the coverage of the anti-metal layer 100.

[0047] As Figure 2 shown, the scoring lines 800 penetrate through the second substrate layer 402 and the detection line 302, and are used to increase the easy-to-tear performance. The shape of the scoring lines 800 includes any one of a straight line, an arc, a broken line, a wavy line, and a curve. The detection line 302 is in an irregular shape, a square, a rectangle, or any one of the shapes with a wider upper part and a narrower lower part or a narrower upper part and a wider lower part.

[0048] The antenna body 301 is used for external communication: When the electronic tag is scanned, the bridge conduction point 600, the bridge layer 500, the antenna body 301, and the chip 700 form a loop to achieve the purpose of the scanner obtaining information. The process is the same as the existing electronic tag scanning principle.

[0049] When the commodity packaging is torn and the antenna is subjected to an external force, refer to Figure 2 , the antenna body 301 and the detection line 302 of the antenna layer 300 are subjected to opposite acting forces, and the scoring pattern 800 is torn ( Figure 2 the dotted line in), causing the detection line 302 to break, the antenna layer 300 to separate from the detection line 302, the first antenna loop to be disconnected, and the second antenna loop to be complete. The chip 700 records the information of the disconnection of the first antenna loop. At this time, the chip 700 communicates through the second loop, and the information transmitted during subsequent scanning includes the information of the disconnection of the first loop, achieving the purpose of preventing the electronic tag from being used again.

[0050] Among them, Figure 2 and Figure 3 The schematic structural diagrams in combination illustrate the structure of the electronic tag provided by the present invention. Figure 2 and Figure 3 The shaded part in the upper half of the picture shown in is the coverage range of the anti-metal layer 100, covering the area corresponding to the antenna body 301 and the first substrate layer 401; compared with Figure 2 , Figure 3 further respectively illustrate the second substrate layer 402 and the third substrate layer 403. There is a scoring pattern 800 on the second substrate layer 402. Figure 3 The dotted shadow in is the third substrate layer 403. During actual production, the anti-metal layer 100 will cover the chip 700 and part of the detection line 302 according to needs.

[0051] When the above label is used as a bottle label on the top of the bottle cap, the first substrate layer 401 of the label, the corresponding antenna body 301, and the chip 700 are pasted in the inner and outer cover sandwich of the bottle cap top 900 of the upper bottle cap A through an adhesive layer. As Figure 6 shown, the label antenna body 301 is circular, and the detection line 302 is in any shape of irregular shape, square, rectangle, or wider at the top and narrower at the bottom, or narrower at the top and wider at the bottom. Among them, the shape of the first substrate layer 401 matches the shape of the bottle cap top 900.

[0052] Among them, the bottle cap top 900 is a sandwich structure. Once it is buckled, it is not easy to separate without damaging the bottle cap.

[0053] The crosshatch pattern 800 is located at the connection of the upper and lower parts on the side of the bottle cap 100. If the label is applied to a non-metal bottle cap, the anti-metal layer 100 can be removed. The first substrate layer 401 covers the antenna body 301, the second substrate layer 402 covers the part of the detection line 302 with the crosshatch pattern, and the third substrate layer 403 covers the remaining part of the detection line 302. Among them, the third substrate layer 403 is in an irregular shape, square, rectangle, or any one of the shapes with a wider upper part and a narrower lower part or a narrower upper part and a wider lower part.

[0054] In actual use, in order to ensure the easy-tearing performance of the label, refer to Figure 1 , the adhesive layer 1100 at the corresponding positions of the first substrate layer 401 and the third substrate layer 403 uses strong glue, and the adhesive layer 1100 at the corresponding position of the second substrate layer 402 uses ordinary glue.

[0055] When the user unscrews the bottle cap, opposite forces will inevitably be applied to the upper bottle cap and the lower bottle cap, so that the crosshatch pattern 800 cracks, and the corresponding part of the detection line 302 breaks, causing the first circuit to be disconnected.

[0056] When the above label is used as a surface label on the side of the bottle cap, it is usually rectangular (not shown in the figure). The label is pasted on the side of the bottle cap. The first substrate layer 401 is pasted on the outside of the upper bottle cap, the second substrate layer 402 covers the part of the detection line 302 with the crosshatch pattern 800 and is correspondingly pasted at the joint of the upper and lower bottle caps, and the third substrate layer 403 is pasted on the outside of the lower bottle cap. When the bottle cap is unscrewed, the crosshatch pattern 800 is torn open accordingly, and the corresponding part of the detection line 302 breaks, causing the first circuit to be disconnected. Among them, when this label is used as a surface label, it can also be pasted at the sealing connection of the outer packaging of the commodity, such as the sealed part of the packaging bag, the sewing connection of the opening of the flour bag, and the easy-tearing line of the packaging box. In the above application environments, the shape of the first substrate layer 401 matches the shape of the surface label pasted on the commodity (such as a convex / concave circle, rectangle, or the same shape as the commodity trademark, etc.), and the second substrate layer 402 covers the opening of the commodity.

[0057] To sum up, the anti-transfer structure provided by the present invention can ensure that it can be quickly damaged under the action of specific external forces while maintaining the normal use of the whole electronic label, and keep one circuit in the label connected so that the chip can record the message of the breakage of the detection line, achieving the purpose of preventing reuse after being tampered with.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
