Description

TECHNICAL FIELD

[0001] The present application relates to a special-shaped flexible anti-metal radio frequency tag, and belongs to the technical field of radio frequency tags. BACKGROUND

[0002] The flexible anti-metal radio frequency tag adopts special material and structural design, can work stably on the metal surface or in the vicinity of the metal, and effectively eliminates the interference of the metal on the radio frequency signal. The flexible anti-metal tag usually adopts soft and bendable materials such as PET, PI, foam, etc., combined with a special electromagnetic shielding layer, to ensure the stability and accuracy of signal transmission. This feature makes the flexible anti-metal tag an ideal choice for the management of metal assets such as metal shelves, machine equipment, vehicles, and movable pressure steel cylinders.

[0003] The pressure steel cylinder commonly has gas bottles and fire extinguishers, etc. These articles are generally densely arranged and placed during transportation and storage. The existing flexible anti-metal radio frequency tag is generally rectangular and is pasted on the bottle body, so it will be affected by the surrounding steel cylinders when densely arranged, which will affect the radio frequency signal, resulting in that the tag placed on the middle steel cylinder cannot be read. SUMMARY

[0004] In order to solve the problem that the flexible anti-metal radio frequency tag is easily affected by the surrounding when pasted on the metal bottle, the utility model provides a special-shaped flexible anti-metal radio frequency tag, which comprises a face material, an antenna layer, a first insulating base material, a conductive film, a pressure-sensitive adhesive layer and a release paper from top to bottom, the antenna layer comprises an antenna and a chip connected to the antenna, characterized in that the tag forms a ring with a notch, and the antenna and the conductive film are connected on the side.

[0005] The special-shaped flexible anti-metal radio frequency tag of the utility model is pasted on the neck of the metal bottle. The neck of the pressure steel cylinder is the place where the bottle body and the outlet are connected, and generally has an approximate plane. When the tag is used, the release paper is torn off, the face material is pasted on the plane with the face material facing up, so that the signal radiation surface of the tag faces up, the signal is not easily affected by the surrounding steel cylinders, and the tag is convenient to read. And because the tag has a notch, it can be conveniently pasted around the outlet. BRIEF DESCRIPTION OF DRAWINGS

[0011] Explanation of reference numerals: 10 - the label of the utility model, 101 - the antenna layer, 201 - the first insulating base material, 301 - the second insulating base material, 501 - the conductive film, 11 - the folding line, 300 - the glue layer, 600 - the adhesive layer, 700 - the release paper, 800 - the face material. DETAILED DESCRIPTION

[0012] It needs to be explained in advance that the "upper" and "lower" mentioned in the utility model are defined in the state that the metal-resistant radio frequency label is adhered to the article, the direction of the label close to the article is "lower", and the other direction is "upper". The face material and the antenna layer of the special-shaped flexible metal-resistant radio frequency label, the antenna and the chip, the antenna layer and the insulating material, and the conductive film layer and the insulating material are all bonded by glue, because the bonding is a conventional structure and does not affect the technical problems to be solved by the structure of the utility model patent, therefore, no identification or mention is made in the illustration and the description.

[0013] The special-shaped flexible metal-resistant radio frequency label of the utility model comprises, from top to bottom, a face material (800), an antenna layer (101), a first insulating base material (201), a conductive film (501), an adhesive layer (600) and a release paper (700), the antenna layer (101) comprises an antenna and a chip connected on the antenna, and the label forms a notched ring, and the antenna and the conductive film are connected on the side surface.

[0014] When the special-shaped flexible metal-resistant radio frequency label is adhered to the metal bottle mouth, the conductive film layer directly contacts the metal bottle body, forms a grounding surface, thereby taking the metal surface as a part of the radio frequency electronic label, so that the direction of the signal reflected by the metal surface is consistent with the signal emitted by the radio frequency electronic label itself, and the radiation efficiency of the radio frequency antenna adhered to the metal surface is enhanced.

[0015] As shown in Figures 1 to 4 The antenna layer (101) and the conductive film (501) of the special-shaped flexible metal-resistant radio frequency label (10) of the utility model are attached to the same surface of the same insulating base material. Glue is coated on the other surface of the insulating base material, and then the conductive film (501) is adhered to the other surface of the insulating base material along the folding line (11). Figure 4The folding line (11) is folded to form the antenna layer (101), the first insulating base material (201), the second insulating base material (301) and the conductive film (501), so that the antenna and the conductive film (501) are connected on the label side, then the face material (800) is attached on the antenna layer (101), the adhesive layer (600) is coated under the conductive film, and the release paper (700) is attached, so that the special-shaped flexible anti-metal radio frequency label (10) of the utility model is obtained. Figure 2 As shown, the anti-metal radio frequency label (10) sequentially comprises the face material (800), the antenna layer (101), the first insulating base material (201), the glue layer (300), the second insulating base material (301), the conductive film (501), the adhesive layer (600) and the release paper (700) from top to bottom, the antenna layer (101) comprises the antenna and the chip connected on the antenna, the second insulating base material (301) is obtained after the first insulating base material (201) is extended and folded along the folding line (11), and the conductive film (501) is attached below the second insulating base material (301). The anti-metal radio frequency label (10) forms a notched ring, and the antenna and the conductive film are connected on the side.

[0016] That is to say, the second insulating base material (301) can be obtained after the first insulating base material (201) is extended and folded along the folding line (11), and the conductive film (501) is attached below the second insulating base material (301). The conductive film (501) can be obtained after the antenna layer (101) is extended and folded along the folding line (11).

[0017] As shown, Figure 4 As shown, the folding line (11) of the utility model is not necessarily a line marked on the label, but represents a folding line formed when some parts of the label are folded.

[0018] Preferably, the area surrounded by the outer contour of the conductive film (501) and the antenna layer (101) is symmetrical with the folding line (11) as the axis of symmetry. In this way, the grounding surface of the label can be maximized when the size of the label is limited within a certain specification.

[0019] Preferably, the antenna and the conductive film (501) are of the same material and are connected at the folding line (11). With this structure, the antenna and the conductive film layer of the special-shaped flexible anti-metal radio frequency label of the utility model can be integrally formed during production, simplifying the process flow.

[0020] Preferably, the first insulating base material (201) and the second insulating base material (301) further comprise a foam layer. The foam layer is used to appropriately increase the distance between the antenna and the conductive film, so that the waveforms of the signals reflected by the metal surface and the signals emitted by the radio frequency electronic tag itself form a superposition effect, enhancing the radiation efficiency of the label on the signals.

[0021] The special-shaped flexible anti-metal radio frequency tag is a ring with a notch, which is convenient to paste to the bottle opening of the pressure steel bottle.

[0022] The special-shaped flexible anti-metal radio frequency tag is not necessarily a circular ring with a notch, but also can be an elliptical ring or a square ring with a notch, which is determined according to the shape of the pasting position.

[0023] Figure 5 The special-shaped flexible anti-metal radio frequency tag is not necessarily a circular ring with a notch, but also can be an elliptical ring or a square ring with a notch, which is determined according to the shape of the pasting position.
