Description

    The present invention relates to an RFID (Radio Frequency Identification) tag and an attachment method thereof, and more particularly to an RFID tag for attachment to a metal product and an attachment method thereof.

    Conventionally, an RFID tag equipped with an RFID inlet that has an IC chip and an RFID antenna and can wirelessly write and read data is attached to various items, and various data about these items are read and written. It is used in various fields such as data management.

Therefore, when the article is made of metal, if the RFID tag is attached in a state where it is too close to the article, there is a problem that data communication is likely to be hindered.
In order to solve this problem, there is an RFID tag in which a holding portion of the RFID inlet is bent at a bent portion so that the RFID inlet is separated from other portions to stand like a flag from a metal surface.

However, such an RFID tag is made of paper and is not stable because the bent portion is not fixed, its standing state is unstable, and there is a difference in data communication performance depending on the mounting condition of the RFID tag. It has a problem in long-term use and environmental resistance.
Furthermore, since a double-sided tape or the like is used to attach the RFID tag to a metal product, there is a problem that the product cannot be used in the case of a product having a surface that is difficult to fix with the double-sided tape.

    In the present invention, since the RFID band is attached to the metal product or other article by inserting the binding band through the through hole of the tag base material, the RFID inlet is stably and reliably attached over a long period of time while being separated from the surface of the article. An RFID tag capable of ensuring the data communication function and its mounting method have been realized.

Next, the RFID tag 1 and its mounting method according to the first embodiment of the present invention will be described with reference to FIGS.
1 is a plan view of the RFID tag 1, FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1, FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 2 and the RFID inlet 3.

    The tag base material 2 is a sheet base material made of, for example, a synthetic resin having predetermined flexibility or elasticity and rigidity, and has an RFID inlet 3 therein.

The RFID inlet 3 includes an inlet base 4 made of, for example, polyethylene terephthalate or a laminated film thereof, an IC chip 5 and an RFID antenna 6 and can perform wireless data communication.
The RFID inlet 3 is, for example, UHF band (300 MHz to 3 GHz (preferably 860 to 960 MHz, more specifically 433 MHz, 900 MHz, 915 to 928 MHz, 950 to 958 MHz) or microwave (1 to 30 GHz, specifically 2 .45 GHz), HF band (3 MHz to 30 MHz (preferably 13.56 MHz)), 135 kHz or lower, and other necessary radio waves in a predetermined frequency band and electromagnetic action, etc. are required for the IC chip 5 via the RFID antenna 6. Read and write data (data communication) wirelessly.
However, the specific configurations of the IC chip 5 and the RFID antenna 6 are appropriate according to the radio waves used.
In particular, in the case of using a radio wave having a wavelength in the UHF band (for example, 860 to 960 MHz), the communication distance is usually about 5 to 10 m, and applications in various fields are expected.

In the tag base 2, a through hole 8 for inserting the binding band 7 (FIGS. 5 and 6, described later) is formed at a position avoiding the area of the RFID inlet 3.
The through hole 8 penetrates in the thickness direction of the tag base 2 and has a thickness direction through hole 8A having an elongated rectangular shape (see FIG. 1) and the thickness inside the tag base 2. The internal through-hole 8B having the same width that communicates with the directional through-hole 8A and penetrates to the edge of the tag base 2 and extends parallel to the surface of the tag base 2. The thickness direction through hole 8A may be formed in a slit shape as long as the tail portion 17 and the band main body 15 of the binding band 7 can be inserted.
The tag base 2 includes a standing base region 2A for raising and separating the RFID inlet 3 with respect to the article with the thickness direction through-hole 8A as a boundary, and an RFID inlet 3 and from the standing base region 2A. This is defined in an upright inlet holding region 2B.

Further, since the tag base 2 has predetermined flexibility or elasticity and rigidity, it is bent along the through hole 8 (thickness direction through hole 8A), specifically, along the opening length direction of the through hole 8. The portion 9 can be bent.
In order to ensure this flexibility, a cut or broken line 10 (imaginary line in FIG. 1) is formed in advance along the bent portion 9 in the lateral portion of the thickness direction through hole 8A as necessary. It may be left.
As shown in FIG. 1, the standing base region 2 </ b> A is a region located below the bent portion 9 in the drawing, and the inlet holding region 2 </ b> B is a region located above the bent portion 9.

The cross-sectional structure of the RFID tag 1 (tag base material 2) shown in FIG. 2 and FIG. 3 is not limited to a single layer structure, and can be configured by any method such as a lamination process, an injection molding process, or a combination process thereof. For example, a laminated structure as shown in FIG.
That is, FIG. 4 is an exploded cross-sectional view of the RFID tag 1 similar to FIG. 3, and the tag base material 2 includes a first base material layer 11 on the surface side, a second base material layer 12 in the middle, and While having the 3rd base material layer 13 on the back side, RFID inlet 3 is attached to the 2nd base material layer 12 with adhesives 14 or the like.
The second base material layer 12 to which the RFID inlet 3 is attached is laminated and covered with the first base material layer 11 and the third base material layer 13, and the RFID inlet 3 on the inner layer side can be firmly protected. it can.

The first base material layer 11 and the third base material layer 13 are made of a soft material to ensure flexibility or elasticity, and the second base material layer 12 is made of a hard material. By doing so, the necessary rigidity is obtained.
For example, as the soft material, a soft vinyl chloride material or any other material is adopted.
As the hard material, PET (polyethylene terephthalate) -G and other arbitrary materials are adopted.

    FIG. 5 is a side view of the binding band 7, and FIG. 6 is an enlarged cross-sectional view of the main part of the binding band 7. The binding band 7 is generally available and is made of, for example, nylon. A strap-shaped band main body 15 having a predetermined length, a bulged head portion 16 formed at one end of the band main body 15, and a taper formed at the other end of the band main body 15. And a tail portion 17 having a shape.

    In particular, as shown in FIG. 6, a through engagement hole 18 is formed in the head portion 16, and a fixing elastic engagement protrusion 19 is formed in the through engagement hole 18.

On one surface of the band main body 15, an uneven belt-like engagement that engages with the fixing elastic engagement protrusion 19 and can be fixed by tightening the entire binding band 7 into a ring shape having an arbitrary circumferential length. A joint portion 20 is formed.
Further, an uneven portion 21 is formed on one surface of the tail portion 17 so that the tail portion 17 can be easily pinched.
Accordingly, the tail portion 17 is first inserted into the through hole 8 of the RFID tag 1 and is also inserted into the through engagement hole 18 of the head portion 16, and an arbitrary portion of the belt-like engagement portion 20 is attached to the fixing elastic engagement protrusion 19. By engaging the band main body 15 into a ring shape having a predetermined circumferential length, the RFID tag 1 can be attached to an article (metal product M, FIG. 7, described later).

    However, the through hole 8 (FIGS. 1 and 3) needs to be formed smaller than the head portion 16 of the binding band 7.

In the RFID tag 1 having such a configuration, the RFID tag 1 can be attached to an arbitrary article (for example, the metal product M) using the binding band 7.
That is, FIG. 7 is a side view showing a state in which the RFID tag 1 is attached to an arbitrary metal product M using the binding band 7, and FIG. 8 is an illustration of attaching the RFID tag 1 to the metal product M using the binding band 7. It is a side view which shows the state.
As shown in FIG. 7, the binding band 7 is connected from the tail portion 17 to the through hole 8 of the tag base material 2 (from the thickness direction through hole 8A to the internal through hole 8B, more precisely, the thickness of the thickness direction through hole 8A. The band main body 15 is hung on the metal product M in a state of being inserted into the internal through hole 8B) from the half portion in the vertical direction, and the tail portion 17 is inserted into the through engagement hole 18 of the head portion 16.

    Next, as shown in FIG. 8, the tail portion 17 is further pulled out with respect to the head portion 16, and the metal product M is tightened by the ring-shaped band body 15, and the tag base is attached to the head portion 16 of the binding band 7. Since the standing base region 2A is in close contact with the outer surface of the metal product M by climbing the material 2, the inlet holding region 2B is bent at the portion of the bent portion 9 and stands up from the metal product M. The RFID tag 1 can be attached to the metal product M so that the RFID inlet 3 in the inlet holding region 2B is separated from the metal product M. Therefore, since the RFID inlet 3 is kept away from the metal product M, the data communication function can be maintained.

However, since the engagement state of the fixing elastic engagement protrusion 19 and the concavo-convex belt-like engagement portion 20 in the head portion 16 is maintained, the tag base material 2 rides on the head portion 16 of the binding band 7. The state is fixed, and the state where the RFID inlet 3 is separated from the metal product M can be stably and reliably realized.
In particular, since the band main body 15 of the binding band 7 is inserted into the internal through-hole 8B and is effectively integrated with the rising base region 2A of the tag base member 2, the rising base region 2A is outside the metal product M. The RFID tag 1 can be fixed in close contact with the surface.

Further, since the band main body 16 or the tail portion 17 has a predetermined rigidity, the tag base 2 in a direction in which the tail portion 17 of the binding band 7 further separates the inlet holding region 2B (RFID inlet 3) from the metal product M. Since the (inlet holding area 2B) can be biased, the standing posture of the inlet holding area 2B by the head portion 16 can be supplementarily maintained.
In addition, when the tail part 17 is too long, the front-end | tip part can also be cut off as needed.

In the present invention, the RFID tag 1 can be attached by inserting only through the thickness direction through hole 8A without inserting the binding band 7 (tail portion 17) into the internal through hole 8B of the through hole 8.
That is, FIG. 9 is a side view showing the middle of a state in which the RFID tag 1 is attached to an arbitrary metal product M using the binding band 7 by another attachment method, and FIG. 10 is a side view of the RFID tag 1 using the binding band 7. It is a side view which shows the state attached to the metal product M.

    As shown in FIG. 9, the band body 15 is wound around the metal product M in a state where the binding band 7 is inserted from the tail portion 17 into the through hole 8 (thickness direction through hole 8A) of the tag base member 2, and the tail The portion 17 is inserted through the through-engagement hole 18 of the head portion 16.

    Next, as shown in FIG. 10, the tail portion 17 is further pulled out with respect to the head portion 16, and the metal product M is tightened by the ring-shaped band body 15, and the tag base is attached to the head portion 16 of the binding band 7. Since the standing base region 2A is in close contact with the outer surface of the metal product M by climbing the material 2, the inlet holding region 2B is bent at the portion of the bent portion 9 and stands up from the metal product M. The RFID tag 1 can be attached to the metal product M so that the RFID inlet 3 is separated from the metal product M.

    However, as already described with reference to FIGS. 7 and 8, since the engagement state of the fixing elastic engagement protrusion 19 and the uneven belt-shaped engagement portion 20 in the head portion 16 is maintained, The state in which the tag base material 2 rides on the head portion 16 of the binding band 7 is fixed, and the state in which the RFID inlet 3 is separated from the metal product M can be stably and reliably realized. In this case, it is desirable that the thickness direction through hole 8A has a size close to the cross section of the band main body 15 of the binding band 7 and is not easily loosened.

    Similarly, since the band body 16 or the tail portion 17 has a predetermined rigidity, the tail portion 17 of the binding band 7 causes the tag holding base 2B (RFID inlet 3) to move further away from the metal product M. Since the material 2 can be urged, the standing posture of the inlet holding region 2B by the head portion 16 can be supplementarily maintained.

In the present invention, the shape, orientation, position, and number of the through holes 8 as well as the shape of the tag base 2 are the same as the size and width of the RFID antenna 6 of the RFID inlet 3, the shape and size of the metal product M, It can be arbitrarily selected according to the type of the binding band 7 or the like.
For example, FIG. 11 is a plan view of an RFID tag 30 according to a second embodiment of the present invention. In the RFID tag 30, the through holes 8 extend laterally along the bent portion 9 in the tag base 2. At least a plurality (two in the illustrated example) are formed in parallel.
Other configurations are substantially the same as the RFID tag 1 described above.

    Even in the RFID tag 30 having such a configuration, the binding band 7 can be inserted and engaged with each through-hole 8, and the RFID tag 30 (particularly, the RFID antenna 6) has a size that spreads in the lateral direction. It is possible to stably and securely attach to the required metal product M, and to stand the inlet holding region 2B (RFID inlet 3) away from the metal product M, thereby extending the communication distance. .
