Description

  The present invention relates to a non-contact type data receiving / transmitting body capable of receiving information from the outside using electromagnetic waves as a medium, and transmitting information to the outside, such as an information recording medium for RFID (Radio Frequency IDentification).

An IC label, which is an example of a non-contact type data receiving / transmitting body, includes an inlet composed of a base substrate, an antenna provided on one side of the base substrate, and an IC chip connected to each other. When an electromagnetic wave is received, an electromotive force is generated in the antenna due to a resonance action. The electromotive force activates the IC chip in the IC label, converts the information in the IC chip into a signal, and this signal is transmitted from the IC label antenna. The
A signal transmitted from the IC label is received by the antenna of the reader / writer, sent to the data processing device via the controller, and data processing such as identification is performed.

  Such a contactless data receiving / transmitting body such as an IC label is used for, for example, an article management application. In particular, if the contactless data receiver / transmitter is applied to the management of many kinds of articles and machine parts having a large number of parts, the article itself can be identified without visual inspection. It is very effective because it can improve the efficiency of inventory management and inventory management.

  When the non-contact type data receiving / transmitting body is used for the management of the article, it is directly attached to the target article. Therefore, depending on the use of the article, the non-contact type data receiving / transmitting body may be damaged by an external impact, and the communication function may be impaired. Therefore, a non-contact type data receiving / transmitting body having a structure capable of withstanding an external impact by storing an inlet in a case or coating with a resin to provide a protective structure has been proposed.

As a manufacturing method of the non-contact type data transmitter / receiver having such a structure, the following can be cited (for example, see Patent Document 1).
For example, an inlet is provided on the original fabric sheet, and a cover sheet of the same quality as the original fabric sheet is bonded to the original fabric sheet by thermocompression bonding or a resin adhesive so as to cover the inlet, A method of obtaining a disk-shaped non-contact type data receiving / transmitting body in which an inlet is embedded in a resin by punching a laminated body made of a cover sheet in a circular shape in the laminating direction (hereinafter referred to as “first” For example).

In addition, after the inlet is inserted into the injection mold, the molten thermoplastic resin is allowed to flow into the mold, or a thermosetting resin is allowed to flow into the mold so that the inlet is embedded in the resin. And a method of obtaining a non-contact type data receiving / transmitting body formed in a predetermined shape by a mold (hereinafter referred to as “second method” for the sake of simplicity).

  By the way, in the first method, it is difficult to reduce the thickness of the non-contact type data receiving / transmitting body because the raw sheet needs to have a minimum thickness that can withstand the tension and pressure when punching into a circle. There was a problem. In addition, since the raw sheet and the cover sheet do not have a portion that absorbs the thickness of the IC chip, there is a problem that the pressure load on the IC chip increases. In addition, the adhesiveness between the original sheet and the cover sheet is poor, and as a result of molding by punching, the joint end surfaces of both are exposed, so when an external force is applied, the joint surface between the original sheet and the cover sheet There was a possibility that the both peeled off and the inlet was exposed. Furthermore, since moisture and chemicals easily penetrate into the inside from the joint surface between the raw sheet and the cover sheet, the non-contact type data receiver / transmitter manufactured by this method is inferior in water resistance and chemical resistance.

  Further, in the second method, the pressure is applied to the inlet more than necessary at the time of injection molding, and the IC chip or the antenna may be damaged. In addition, if the thickness of the base substrate is reduced in order to reduce the thickness of the non-contact type data transmitter / receiver by this method, when the resin flows into the mold, the pressure of the resin causes the base substrate to There was a problem that it was difficult to reduce the thickness because cracks occurred.

Even if the housing and the cover are formed of different materials, an external force is applied to the non-contact type data receiving / transmitting body, so that both peel off at the interface between the housing and the cover, and the inlet is exposed. There is no damage. In addition, the non-contact type data receiving / transmitting body does not peel off at the interface between the casing and the cover, so that moisture and chemicals do not penetrate inside, and has excellent water resistance and chemical resistance. Yes. Further, if the casing is formed of a thermoplastic resin, a thin structure can be obtained while sufficiently securing durability against external forces and chemical resistance. Furthermore, if the casing is formed of a thermoplastic resin, the durability and chemical resistance against external force can be sufficiently secured, and a thin structure can be achieved, and the surface can be curved.

  According to the non-contact type data receiving / transmitting body of the present invention, since the inlet is arranged inside the recessed portion with respect to the plane formed by the outer peripheral end of the housing, the inlet is arranged in the recessed portion of the housing. Since everything is covered with the cover, even if the case and the cover are made of different materials, the external force (especially from the side) is applied to the non-contact type data receiving / transmitting body. Both peel off at the body interface, and the inlet is not exposed or damaged. The non-contact type data receiving / transmitting body is attached to the target article via an adhesive or an adhesive on the outer peripheral end surface of the casing.

The electric current path of the coating film forming the antenna 12 is formed when the conductive fine particles forming the coating film contact each other, and the resistance value of the coating film is on the order of 10 ⁻⁵ Ω · cm.

  Further, as the polymer type conductive ink in the present invention, known ones such as a photo-curing type, a permeation drying type, and a solvent volatilization type are used in addition to the thermosetting type.

  The photocurable polymer type conductive ink contains a photocurable resin in the resin composition and has a short curing time, so that the production efficiency can be improved. Examples of the photocurable polymer conductive ink include, for example, a thermoplastic resin alone or a blend resin composition of a thermoplastic resin and a crosslinkable resin (especially a crosslinkable resin composed of polyester and isocyanate) and 60 masses of conductive fine particles. % Or more and 10% by mass or more of a polyester resin, that is, a solvent volatile type or a crosslinked / thermoplastic combined type (however, the thermoplastic type is 50% by mass or more), or a thermoplastic resin Or a blend resin composition of a thermoplastic resin and a crosslinkable resin (especially a crosslinkable resin composed of polyester and isocyanate), in which a polyester resin is blended in an amount of 10% by mass or more, that is, a crosslinkable type or a crosslinkable / heatable type A plastic combination type is preferably used.

  Although the material which comprises the housing | casing 16 is not specifically limited, For example, resin, such as a thermoplastic resin, a thermosetting resin, a reactive resin, ceramics, glass, a metal, etc. are mentioned. The thickness of the housing | casing 16 should just be a grade which can store the inlet 14 and the covering body 17 in the recessed part 16a, and it is preferable that it is as thin as possible.

  Examples of the thermoplastic resin forming the housing 16 include vinyl chloride, vinyl acetate, vinyl chloride-vinyl acetate copolymer, vinyl chloride-vinylidene chloride copolymer, vinyl chloride-acrylonitrile copolymer, acrylate ester-acrylonitrile. Copolymer, Acrylate ester-Vinyl chloride-Vinylidene chloride copolymer, Acrylate ester-Vinylidene chloride copolymer, Methacrylate ester-Vinylidene chloride copolymer, Methacrylate ester-Vinyl chloride copolymer, Methacrylate ester -Ethylene copolymer, polyvinyl fluoride, vinylidene chloride-acrylonitrile copolymer, acrylonitrile-butadiene copolymer, polyamide resin, polyvinyl butyral, cellulose derivatives (cellulose acetate butyrate, cellulose diacetate, cellulose) Triacetate, cellulose propionate, nitrocellulose), styrene butadiene copolymer, polyurethane resin, polyester resin, amino resin, or polymers such as styrene rubber, fluorine rubber, silicon rubber, ethylene / propylene copolymer rubber Synthetic rubber materials and the like.

  The ceramic, glass, or metal forming the housing 16 is not particularly limited, and any material can be used as long as the concave portion 16a can be formed to the extent that the inlet 14 and the covering 17 can be stored.

  Of the materials forming the casing 16, a resin is preferable because it can be easily formed into a predetermined shape. Among the resins, the casing 16 is formed using a thin sheet-like base material. Even if it is molded, a thermoplastic resin is more preferable because the recess 16a is less likely to crack.

Examples of the material forming the covering 17 include resins such as thermoplastic resins, reactive resins, and thermosetting resins.
As the thermoplastic resin or reactive resin, the same resin as that forming the housing 16 is used.
The thermosetting resin is not particularly limited as long as it can be covered so as to cover the inlet 14 in a state where the inlet 14 is stored in the recess 16a of the housing 16, for example. An epoxy resin, a urethane resin, etc. are mentioned. Among these, as the thermosetting resin forming the covering body 17, when the casing 16 is made of a thermoplastic resin, a resin having a curing temperature lower than the melting point of the thermoplastic resin is used.

  By the way, in order to improve the durability against the external force and chemical resistance of the non-contact type data receiving / transmitting body 10, in order to improve the adhesion between the casing 16 and the covering body 17, both materials are made the same. It is desirable. However, if the casing 16 and the covering 17 are made of the same material, the resin forming the covering 17 is heated when the resin forming the covering 17 is filled in the recess 16a in order to cover the inlet 14. In the case of a curable resin, the case 16 is deformed or becomes a fluid depending on the curing temperature, and in the case of a thermoplastic resin, since it is melted, it is not preferable. In addition, when the covering body 17 is a thermoplastic resin, it takes a short time to solidify and it is difficult to fill the recess 16a. Therefore, the material constituting the covering body 17 is preferably a reactive resin or a thermoplastic resin. Furthermore, since the reactive resin is likely to be dense and dense when solidified, a thermoplastic resin is more preferable as the material constituting the covering 17.

  Thus, according to the non-contact type data receiving / transmitting body 10 of this embodiment, since the inlet 14 is arranged inside the recess 16a with respect to the plane formed by the outer peripheral end 16b of the housing 16, the inlet 14 is Since the entire outer periphery of the recess 16a of the housing 16 is covered with the cover 17, even if the housing 16 and the cover 17 are formed of different materials, an external force ( In particular, by adding (from the side), both of them are peeled off at the contact surface (interface) between the housing 16 and the covering 17 and the inlet 14 is not exposed or damaged. The non-contact type data receiving / transmitting body 10 is affixed to the target article (adhered body) on the surface of the casing 16 on the outer peripheral end 16b side via an adhesive or a pressure-sensitive adhesive. In this state, the interface between the casing 16 and the covering 17 is not exposed to the outside, so that sufficient chemical resistance can be secured during use. Further, since the non-contact type data receiving / transmitting body 10 is not peeled off at the contact surface (interface) between the casing 16 and the covering body 17, moisture and chemicals do not penetrate inside, and the water resistance Excellent chemical resistance. Further, if the casing 16 is formed of a thermoplastic resin, a thin structure can be achieved while sufficiently ensuring durability and chemical resistance against external forces. Furthermore, if the casing 16 is formed of a thermoplastic resin, it can sufficiently ensure durability against external forces and chemical resistance, and can have a thin structure as well as a curved surface.

In the non-contact type data receiving / transmitting body of the present invention, the shape of the housing for storing the inlet is appropriately determined according to the shape of the target article, the place where the non-contact type data receiving / transmitting body is attached, and the like.
