Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.
The invention is further described below with reference to the drawings and specific examples, which are not intended to be limiting.
In a preferred embodiment of the present invention, as shown in fig. 2, a fragile electronic tag is attached to a paper surface 5, the fragile electronic tag includes a substrate 1, the substrate 1 includes an upper surface paper layer 11 and a lower first film layer 12, at least one tag chip 21 and at least one tag antenna 22 are disposed between the surface paper layer 11 and the first film layer 12, the tag chip 21 and the tag antenna 22 are electrically connected, and an adhesive is disposed between the surface paper layer 11 and the first film layer 12 for bonding;
as shown in fig. 1 and 2, an adhesive part is disposed under the substrate, and the adhesive part includes at least one fixing area 31 and at least one transferring area 32;
as shown in fig. 3, each fixing area 31 corresponds to a tag chip 21 and is disposed below the corresponding tag chip 21;
as shown in fig. 3, each transfer area 32 corresponds to a tag antenna 22 and is disposed below the position of the corresponding tag antenna 22;
each fixing area 31 is provided with a second film layer, the upper surface and the lower surface of the second film layer are provided with a layer of strong glue, and the second film layer is used for fixedly gluing the fixing areas 31 on the paper surface 5 and the substrate 1;
each transfer area 32 is provided with a third film layer, the upper surface of the third film layer is provided with a layer of strong glue, the lower surface of the third film layer is provided with a layer of transferable glue, and the third film layer is used for adhering the transfer area 32 to the paper surface 5 in a strippable manner and fixedly adhering the transfer area 32 to the substrate 1.
Specifically, in this embodiment, as shown in fig. 4, the second film layer is provided by the fixing section 31, the third film layer is provided by the transfer section 32, and the fragile effect is obtained by pulling out the transfer section 32 away from the paper surface 5. The substrate 1, the second film layer and the paper surface 5 in the area where the fixing area 31 is located are all adhered by strong adhesive with high viscosity, and when the transfer area 32 is peeled off, the fixing area 31 generates a force towards the paper surface 5, and the force away from the paper surface 5 peeled off by the transfer area 32 is matched with the force away from the paper surface 5, so that the transfer area 32 is separated from the fixing area 31. Because the transfer area 32 and the fixing area 31 are bonded with the substrate 1 through the strong adhesive with larger viscosity, and the transfer area 32 and the fixing area 31 correspond to different tag chips 21 and tag antennas 22 respectively, the substrate is separated into a plurality of blocks according to the positions of the transfer area 32 and the fixing area 31 when the transfer area 32 is separated from the fixing area 31, so that the electrical connection between the tag chips 21 and the tag antennas 22 is cut off, and the frangible effect of the tag is realized.
Wherein the adhesive inside the substrate 1 is used for adhering the tag chip 21 and the tag antenna 22 inside the substrate by the adhesion of the face paper layer 11 and the first film layer 12.
The tag chip 21 includes a chip, a chip peripheral circuit, and a chip peripheral antenna circuit inside.
The strong glue is used for bonding two sides bonded with each other to generate a large bonding effect, is not easy to peel off on materials such as paper, realizes the mutual fixed bonding of the substrate 1, the second film layer and the paper surface 5 in the fixed area 31, and bonds the substrate 1 and the third film layer in the transfer area 32 to generate a fixed bonding effect.
The transferable glue has a certain viscosity, which is lower than that of the strong glue, is relatively easy to peel off on materials such as paper, and can realize the peeling effect in the transfer area 32 without damaging the paper surface. The fixing section 31 and the transfer section 32 are different areas under the same plane of the adhesive portion. The fixing section 31 and the transfer section 32 are arranged at intervals.
In a preferred embodiment of the present invention, the strong adhesive is an oily self-adhesive.
Specifically, in the embodiment, the oily self-adhesive has the properties of good initial adhesion, strong holding power, large stripping force, good freezing resistance and aging resistance, and the viscosity of the oily self-adhesive is 1500-2000mjpa. The oily self-adhesive has relatively strong viscosity and is not easy to peel off on materials such as paper and the like.
In a preferred embodiment of the present invention, the transferable glue is an aqueous self-adhesive glue.
Specifically, in the embodiment, the water-based self-adhesive is mainly copolymerized and synthesized by acrylic monomers and auxiliary materials, and has excellent portability. The viscosity of the aqueous self-adhesive is 150-200mjpa.s.
In a preferred embodiment of the present invention, the surface paper layer 11 is made of one of PET printing material, PVC printing material, copper plate printing material or PP synthetic paper printing material. The PP synthetic paper is made by mixing and pressing polypropylene resin, polyethylene resin, natural stone powder and other main raw materials.
In a preferred embodiment of the present invention, the first film layer 12 is made of one of PI brittle film, PET brittle film or OPP brittle film.
Specifically, in this embodiment, the PI frangible film is a polyimide film, the PET frangible film is a polyester film, and the OPP film is an o-phenylphenol film.
In a preferred embodiment of the present invention, as shown in fig. 1 and 4, the fragile electronic tag further includes at least one paper protection area 4, each paper protection area 4 is disposed at a lower layer of a corresponding fixing area 31, the upper surface of the paper protection area 4 is glued to the fixing area 31 by a strong glue, and the lower surface of the paper protection area 4 is glued to the paper surface 5 by a strong glue.
Specifically, in this embodiment, the paper protection area 4 is used to weaken local stress intensity of paper when the label is peeled, so as to prevent the paper surface 5 from being damaged; after the tag has a frangible effect, the paper protective zone 4 remains on the paper, making the residue more regular. Before the tag produces a frangible effect, there is an upper layer tag structure such that the paper protection zone 4 is obscured from removal; after the tag has a frangible effect, the upper layer tag structure is lost, so that the paper protecting area 4 is easier to remove.
In a preferred embodiment of the invention, each paper protection zone 4 covers a corresponding fixing zone 31, according to the illustration of fig. 1.
Specifically, in the present embodiment, the outer peripheral contour of the paper protecting area 4 is larger than the outer peripheral contour of the fixing area 31. When the label is peeled off, the stress area of the paper surface 5 is increased, so that the stress of the paper surface 5 is uniform, the local stress intensity of the paper surface 5 is reduced, and the paper surface 5 is protected from being damaged.
In a preferred embodiment of the invention, the edges of the paper protecting zone 4 and the edges of the transfer zone 32 overlap each other as shown in fig. 1.
Specifically, in this embodiment, before the label is adhered, when the preset release liner is peeled off, the internal structure of the label still maintains a complete connection state, and the adhesive force of the label structure itself and the tensile force towards the release liner, which is received by the paper protection area 4, counteract, so as to prevent the label from being scrapped due to the brittle effect when the release liner is peeled off.
In a preferred embodiment of the present invention, the tag antenna 22 is one of an etched copper antenna, an etched aluminum antenna, or a silver paste printed antenna.
The tag chip 21 employs a chip that conforms to both a high frequency 13.56MHZ protocol and an ultra high frequency 860-960MHZ protocol.
In a preferred embodiment of the present invention, a release backing paper is disposed at the bottom of the adhesive portion.
Specifically, in this embodiment, when the fragile electronic tag is in an unused state, the release liner is used to protect the adhering portion, and when in use, the release liner is torn off to adhere the fragile electronic tag to the paper surface 5.
