Abstract
Description
The present invention relates to an RF tag for calibration, and more particularly, to an RF tag for calibration, which is provided with an adhesive layer on one side or the other side of an RF tag sheet having an antenna formed on one side thereof so as to be connected to an IC chip, When the tag sheet is continuously attached to a desired product, the tag sheet is thin and exhibits a waterproof function. However, since the tag itself is damaged as well as the antenna itself, And relates to an RF tag for calibration which is absolutely impossible to move after attachment.
In general, RFID (Radio Frequency Identification) transmits and receives information wirelessly through IC chips and antenna coils installed inside. It is used for transportation cards of subways and buses, personal identification tags, company security access and credit cards. And is also widely used as an RFID tag that can be easily carried on the outside.
The NFC (Near Field Communication) tag is one of RFID (radio tag) technologies and is a non-contact communication technology using a frequency band of 13.56 MHz. Since the communication distance is short, It is a short distance communication technology.
As an example, the prior art related to a system for identifying user information using the NFC tag is disclosed in, for example, Korean Patent Application No. 10-2012-0042171.
As shown in FIG. 1, the first related art includes an NFC tag for storing user information for use such as a market, travel information, traffic, access control, lock device, etc. and outputting and updating stored information through NFC An
That is, the conventional technique as described above, for example, stores the NFC tag in an identifiable place, and reads the NFC tag through the tag reader to identify the authenticity of the specific user.
For example, a social worker having an NFC tag reader visits a residential area where the elderly person or the handicapped having a welfare card resides, carries out a service, and then the welfare card of the user is authenticated through the NFC tag reader So that they can check the visit.
Also, security guards guarding a specific place, such as a company's laboratory, can patrol the corresponding area equipped with an NFC tag and authenticate through an NFC tag reader to confirm that the area has been patrolled.
However, in the conventional technology as described above, when a user performing service and expense collects all the NFC tags and cards or separates only a part of the NFC tag performing the authentication function, the NFC tag reader There is a problem that the service and the patrol can be authenticated at a time.
That is, in recent years, collecting and collecting the NFC tags in an integrated manner or separating only a part of the NFC tags has become increasingly intelligent, and there is a demand for a technique for preventing copying and theft of such NFC tags.
Meanwhile, in order to solve such a problem, the present inventor filed a Korean Patent Application No. 10-2014-0122326 entitled "NFC tag in which an RF function is broken at the time of separation ", which will be described with reference to FIGS. 2 and 3 .
FIG. 2 is a view for explaining a configuration of an RF tag for calibration according to a preferred embodiment of the present invention, and FIG. 3 is a view for explaining a state of RF tag separation for calibration according to another embodiment of the present invention.

However, the second prior art also has a problem in that a chemical agent which lowers the adhesive strength of the adhesive layer is used or the tag is separated by careful separation. Further, in order to use the above tag for calibration, the printed layer of the surface enjoys a somewhat visible effect. In the second conventional technology, only the antenna is damaged at the time of separation, and the printed layer of the surface is left intact. Han has the limitation that it can not grasp the authenticity and has a problem that it is not suitable for the calibration of slim products because it has a considerable thickness.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a thin RF tag for calibration, which tries to separate a tag from a non-complex and breaks the tag as well as the antenna.

First, a bottom surface and a cross section of the first embodiment of the RF tag for calibration according to the present invention will be described with reference to FIGS. 4 and 5. A bar code, a visible identification mark, And an
An
The
Herein, kaolin, silicone oil, and emulsion may be added as a sub ingredient.
The composition ratios and CAS numbers of the above materials are shown in Table 1.
For reference, calcium carbonate or kaolin The reasons for using it are as follows: 1) the surface is made smooth when the product is made, 2) the transparency of the grain is made more opaque, 3) the rigidity of the product is increased, and 4) And creates an empty space. 5) It minimizes surface electric conductivity (resistance value is infinite). However, when the product is made by using an excessive amount of calcium carbonate or kaolin, it is difficult to form the product.
In particular, although the calcium carbonate and kaolin are both mineral and have similar properties, the reason for adding kaolin is that kaolin has glossiness. However, if too much kaolin is used, the product is broken when it is bent, and the tensile strength is significantly lowered. Therefore, it is preferable to use 3 wt% or less (preferably 2 wt%) or less.
On the other hand, the emulsion may be an emulsion having a surfactant, but a silicone emulsion is preferable, and a nonionic and anionic surfactant is prepared by using an inverse emulsification method using an interfacial chemical property of an emulsifier. Especially, the most stable emulsion was obtained when nonionic surfactant was used. In the most stable surfactant composition, a more stable emulsion was obtained as the particle size was smaller in size and distribution. The silicone emulsion used in the present invention is preferably a silicone emulsion having an average particle diameter of 100 nm or less. Particularly, when the content of the silicone emulsion was 5 wt% or more, the surface was well formed, the peel strength was not changed with the lapse of time, and the bonding force was small at the time of surface separation. In addition, adhesion rate with organic adhesive was also high. The present invention is characterized in that the peeling performance is excellent with a smaller silicon content than in the prior art.
The
The length and shape of the antenna pattern are determined in consideration of the wavelength of the radio wave to be used. The pattern of FIG. 4 is an example of the NFC tag of 13.56 MHz.
Unlike the first embodiment, the antenna pattern of the second embodiment as a tag of an RF frequency band of 900 MHz to 2.4 GHz band is formed by the amount of the central information recording IC chip 425 A
The second embodiment differs from the first embodiment only in the shape of the antenna pattern according to the difference between the wavelength band and the wavelength band, and the technical idea including the material of the
The printing method of the
The RF tag for calibration according to the present invention is attached to the surface of the object 401 to be bonded such as the calibrated scale as shown in FIG. 5, and the information on the object to be calibrated is recorded in the embedded chip of the tag. You can check all histories and calibration information if you bring in a self-reader, and you can record the information and use it as statistical data. In addition, in the past, it was sometimes possible to attach a tag to another product that was not attached to another unauthorized product, and to obtain the authorization by attaching it to the original product only during the calibration. However, according to the present invention, The conventional problems can be solved at once.
And the above tags can be used for refrigerator or non-exchangeable product shipment, for bagging of air cargo freight, for checking authenticity of stocks or precious metals, and for managing company fixtures and test equipment. , And can be widely used in all fields where tags should not be moved.
While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
