Description

Technical Field

[0001] The present invention relates to an RFID-tagged mounting component having an RFID (Radio Frequency Identification) tag embedded in the head of a mounting component such as a headed bolt or a headed pin, a method for manufacturing the RFID-tagged mounting component, the head of the RFID-tagged mounting component, and an RFID tag assembly unit. Background Technology

[0002] RFID tags are components that connect an antenna to an IC chip, and are classified into active and passive types. Active RFID tags have their own power source. Passive RFID tags are powered by radio waves emitted by the reader. RFID tags communicate and exchange data with the reader, reading and writing various data.

[0003] Various mounting components for RFID tags have been provided. For example, Patent Document 1 describes a bolt with a hole formed on the top surface of a head at one end of a threaded portion, which serves as a housing for an IC tag (a type of RFID tag). A plate-shaped magnetic body is disposed at the bottom of the housing. An electromagnetic induction-based non-contact IC tag is mounted on the magnetic body. The housing containing the magnetic body and the IC tag is filled with a heat-resistant resin filler. The opening of the housing is sealed with a ceramic or heat-resistant resin cap.

[0004] A resin coating layer is formed on the outer peripheral surface of the bolt and the outer surface of the cap. This resin coating layer is formed by attaching resin powder to the outer peripheral surface of the bolt and the outer surface of the cap, heating to melt the resin powder, and then cooling the molten resin powder. The molten resin powder also enters the gap between the bolt's housing, the cap, and the filler material. Because of the resin, foreign matter such as dust and rainwater cannot penetrate into this gap. The bolt, covered by the resin coating and containing an IC tag, serves as an IC tag mounting structure for managing information about the device and equipment.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2014-238743 Summary of the Invention The problem that the invention aims to solve

[0006] In the IC tag mounting structure described in Patent Document 1, an IC tag receiving portion is formed at the head of the bolt. A peripheral wall portion surrounding the IC tag is formed within the receiving portion. Furthermore, the bolt is typically made of metal such as steel or an alloy. Therefore, if the IC tag is particularly a passive RFID tag, the communication sensitivity will be hindered by the peripheral wall portion.

[0007] The IC tag mounting structure described in Patent Document 1 enables wireless communication with a reader via an IC tag embedded in the head of a bolt. The sensitivity of this wireless communication varies greatly depending on the usage conditions, such as process management, inventory management, and maintenance on a production line with the IC tag mounting structure installed.

[0037] [Implementation Method 1-1] While referring to Figures 1 to 4 The first example of the first-1 embodiment of the mounting component with RFID tag of the present invention will be described. Figure 1 This is a perspective view showing a first example of the first embodiment of the mounting component with an RFID tag according to the present invention. Figure 2 This is a front cross-sectional view showing the initial step of the manufacturing method of the first example of the first embodiment of the RFID tag mounting component of the present invention. Figure 3 This is a cross-sectional front view of an intermediate step in the manufacturing method of the first example of the first embodiment of the RFID tag mounting component of the present invention. Figure 4 This is a front cross-sectional view showing the final step of the manufacturing method of the first example of the first embodiment of the mounting component with RFID tag of the present invention.

[0038] The RFID-tagged mounting component includes not only fastening components such as bolts or screws that engage with internal threads or nuts, but also pins that are inserted into shaft holes. However, since the RFID-tagged mounting component in Embodiment 1-1 (and similarly in Embodiments 1-2, etc., described later) uses a bolt-like mounting component as an example, it will be mainly described below as a "bolt with an RFID tag." Figure 1 As shown, the bolt with the RFID tag has a shaft-shaped part 1-1, a head 1-2, an RFID (Radio Frequency Identification) tag 1-3, and an enhancement antenna 1-4.

[0039] The shaft-shaped portion 1-1 has an insertion portion 1-11 and a base portion 1-12. The insertion portion 1-11 and the base portion 1-12 are formed of a metal such as aluminum or stainless steel. The insertion portion 1-11 is shaft-shaped and has external threads. However, no external threads are formed near one end of the insertion portion 1-11 (the part that is continuous with the base portion 1-12).

[0040] The base plate portion 1-12 protrudes in the width direction from one end of the insertion portion 1-11. The width direction is orthogonal to the length direction of the insertion portion 1-11. The width direction in the insertion portion 1-11, which has external threads, can also be referred to as radial. The base plate portion 1-12 is formed in a disc shape. The center of the disc-shaped base plate portion 1-12 coincides with the radial center of the insertion portion 1-11. A flat cut surface 1-121 is formed on a portion of the outer peripheral surface of the base plate portion 1-12.

[0041] The head 1-2 is formed by integrating the pedestal part 1-21 on the top surface where the RFID tag 1-3 is mounted, and the cap part 1-22 covering the main part of the pedestal part 1-21.

[0042] The pedestal portion 1-21 is formed by resin molding on the surface side of the base portion 1-12 where the insertion portion 1-11 does not exist. For example... Figure 2 As shown, the pedestal portion 1-21 includes an enlarged diameter portion 1-211 and a protrusion 1-212. The enlarged diameter portion 1-211 is formed in an annular shape surrounding the outer periphery of the base portion 1-12. An arc-shaped locking portion (not shown) is formed on a portion of the inner surface of the enlarged diameter portion 1-211 to engage with the cut surface 1-121 of the base portion 1-12. The protrusion 1-212 protrudes from the center of the surface of the base portion 1-12 in a cylindrical or polygonal prism shape in the direction opposite to that of the insertion portion 1-11. A groove-shaped or recessed lower portion 1-212a is formed on the top surface of the protrusion 1-212 for mounting the RFID tag 1-3. Figure 1 and Figure 3 As shown, the protrusion 1-212 is surrounded by half of the base end side (lower side in the figure) of the helical spring-shaped reinforcing antenna 1-4.

[0043] like Figure 4 As shown, the cap portion 1-22 covers the protrusion 1-212 of the base portion 1-21 and is molded into a cylindrical shape by using resin to seal the RFID tag 1-3 and the reinforcing antenna 1-4. The cap portion 1-22 protrudes towards the surface of the base portion 1-12 by a length slightly longer than or approximately the same as the insertion portion 1-11, and has the same outer diameter as the enlarged portion 1-211. The cap portion 1-22 is formed by inserting a mold (not shown). Although not shown, knurling such as straight lines can also be formed along the length direction on the outer peripheral surface of the cap portion 1-22.

[0044] RFID tag 1-3 is a passive tag. That is, RFID tag 1-3 does not have a built-in battery, but receives radio waves from a reader (not shown) and uses these radio waves as power to operate. RFID tag 1-3 is an ultra-small (e.g., 2.5mm in length, width, and thickness) sheet-like electronic component that combines an IC chip for recording information and an antenna for wireless communication. RFID tag 1-3 is mounted on the lower middle part 1-212a formed on the top surface of the protrusion 1-212 of head 1-2, and is sealed to the cap part 1-22 of head 1-2 by resin molding.

[0045] The reinforcing antenna 1-4 is formed in the shape of a cylindrical helical spring surrounding the protrusion 1-212 of the base portion 1-21, and amplifies the radio waves transmitted and received by the RFID tag 1-3. The illustrated reinforcing antenna 1-4 is depicted in a way that is easy to observe; the actual reinforcing antenna 1-4 may also be formed with spacing, wire diameter, and number of turns not shown. The reinforcing antenna 1-4 is formed from a conductive material including various metals. Regarding the cylindrical helical spring-shaped reinforcing antenna 1-4, the base end is fixed to the surface of the expanded diameter portion 1-211, half of the base end side surrounds the protrusion 1-212, and half of the front end side extends beyond the top surface of the protrusion 1-212. Preferably, the protrusion 1-212 is more than half the length of the reinforcing antenna 1-4. The RFID tag 1-3 is disposed in the middle portion along the length direction of the reinforcing antenna 1-4. The RFID tag 1-13 is disposed at a position away from the metal base portion 1-12, surrounded by the reinforcing antenna 1-4. The enhancement antenna 1-4 is not electrically connected to the RFID tag 1-3. The enhancement antenna 1-4 is coupled to the antenna magnetic field contained in the RFID tag 1-3.

[0046] Here, while referring to Figures 2 to 4 A first manufacturing method for a bolt with an RFID tag, as described in the first example of the first embodiment 1-1, is explained. The first manufacturing method for a bolt with an RFID tag is divided into an initial process, an intermediate process, and a final process.

[0047] Although not illustrated, the shaft-shaped part 1-1 and the base part 1-21 are manufactured separately in the initial process. (See diagram below.) Figure 2 As shown, in the next step after the initial process, the platform portion 1-21 is formed by inserting molten resin. That is, the platform portion 1-21 is formed by inserting the platform portion 1-21 such that the expanded diameter portion 1-211 of the platform portion 1-21 surrounds the outer peripheral surface of the base portion 1-12, and the protrusion 1-212 of the platform portion 1-21 protrudes from the surface of the base portion 1-12. A lower portion 1-212a is formed on the top surface of the protrusion 1-212.

[0048] like Figure 3 As shown, in the intermediate process, the RFID tag 1-3 is assembled onto the top surface by embedding it into the lower middle part 1-212a of the protrusion 1-212 of the initially formed pedestal part 1-21, and the base end of the reinforcing antenna 1-4 is disposed in the expanded diameter part 1-211 of the pedestal part 1-21. The component in which the RFID tag 1-3 is disposed within the reinforcing antenna 1-4 is called a tag module.

[0049] The protrusion 1-212 of the pedestal portion 1-21 and the tag module (RFID tag 1-3 and reinforcing antenna 1-4) are disposed within the cavity of a mold (not shown). The cavity of the mold is a space for molding the cap portion 1-22 of the head 1-2 using resin inserts. With the mold closed, molten resin is filled into the cavity. This molten resin is the same as the molten resin used to mold the pedestal portion 1-21. After the molten resin solidifies, the bolts with the RFID tag 1-3 forming the cap portion 1-22 are completed. Because the pedestal portion 1-21 and the cap portion 1-22 are molded using the same molten resin, they are integrated to the point that the boundary surfaces are unknown or difficult to know. Furthermore, in Figure 4 In order to easily distinguish between the pedestal part 1-21 and the cap part 1-22, a reverse shading line was added.

[0050] In the final process, the bolt with the RFID tag is removed from the cavity by opening the mold. For example... Figure 4 As shown, the cap portion 1-22 of the bolt head 1-2 with the RFID tag secures the tag module (RFID tag 1-3 and reinforcing antenna 1-4). Since the cap portion 1-22 of the head 1-2 and the base portion 1-21 are integrally molded from the same resin, the cap portion 1-22, being integrally formed, will not slide in the circumferential or longitudinal directions. Furthermore, since the engaging portion and the cut portion 1-121 on the outer peripheral surfaces of the expanded diameter portion 1-211 of the base portion 1-21 and the base portion 1-12 engage in a straight line, the head 1-2 and the base portion 1-12 will not rotate freely.

[0051] Next, while referring to Figures 5 to 7 The manufacturing method of the second example of the first embodiment of the bolt with RFID tag will be described in three steps: initial process, intermediate process and final process. Figure 5 This is a front cross-sectional view showing the initial step of the manufacturing method of the second example of the first-1 embodiment of the RFID tag mounting component of the present invention. Figure 6 This is a cross-sectional front view of an intermediate step in the manufacturing method of the second example of the first-1 embodiment of the RFID tag mounting component of the present invention. Figure 7 This is a front cross-sectional view showing the final step of the manufacturing method of the second example of the first-1 embodiment of the RFID tag mounting component of the present invention.

[0052] like Figures 5 to 7As shown, in the second example of the first embodiment of the bolt with RFID tag, a fitting recess 1-122 is formed at the center of the surface of the base portion 1-12 of the shaft portion 1-1, and a fitting protrusion 1-213 is formed at the center of the base end face of the expanded diameter portion of the pedestal portion 1-21. With this bolt with RFID tag, the pedestal portion 1-21 and the base portion 1-12 are integrated by inserting the fitting protrusion 1-213 into the fitting recess 1-122. The enhancement antenna 1-4 is also shaped like a helical spring, similar to the first example.

[0053] In the initial process of manufacturing the second example of such an RFID tag, the shaft portion 1-1 and the base portion 1-21 are manufactured separately. For example... Figure 5 As shown, in the initial process, an RFID tag 1-3 is further assembled into the lower middle portion 1-212a of the protrusion 1-212 of the base portion 1-21. Additionally, an enhancement antenna 1-4 is provided on the expanded diameter portion 1-211 of the base portion 1-21. The RFID tag 1-3 is located at the middle of the enhancement antenna 1-4 along its length. The RFID tag 1-3 assembled in the protrusion 1-212 and the enhancement antenna 1-4 combine to form a tag module.

[0054] like Figure 6 As shown, in the intermediate process, the fitting protrusion 1-213 of the pedestal portion 1-21 is embedded into the fitting recess 1-122 of the base portion 1-12. Furthermore, the reinforcing antenna 4 can also be externally mounted to the protrusion 1-212 after the fitting protrusion 1-213 of the pedestal portion 1-21 is embedded into the fitting recess 1-122 of the base portion 12. In the intermediate process, the tag module (RFID tag and reinforcing antenna 4), the pedestal portion 1-21, and the base portion 1-12 are placed into the mold. Then, with the mold closed, the same molten resin as the pedestal is injected into the cavity. After the molten resin solidifies, the bolt with the RFID tag and cap portion 1-22 is formed. Because the pedestal portion 1-21 and the cap portion 1-22 are formed using the same molten resin, they are integrated to the point that the boundary surface is unknown or difficult to know.

[0055] In the final process, the bolt with the RFID tag is removed from the cavity by opening the mold. This bolt with the RFID tag, like the one manufactured according to the manufacturing method of Example 1, has its head 1-2 designed to be an integral part of the base portion 1-21 and the cap portion 1-22. Therefore, with respect to this bolt with the RFID tag, if the head 1-2 rotates circumferentially, the shaft portion 1-1 will not rotate freely but will rotate integrally.

[0056] Next, while referring to Figures 8 to 11The manufacturing method of the third example of the first-1 embodiment of the bolt with RFID tag will be described in three steps: initial process, intermediate process and final process. Figure 8 This is a front cross-sectional view showing the initial step of the manufacturing method of the third example of the first-1 embodiment of the RFID tag mounting component of the present invention. Figure 9 This is a cross-sectional front view of an intermediate step in the manufacturing method of the third example of the first-1 embodiment of the RFID tag mounting component of the present invention. Figure 10 This is a cross-sectional front view of an intermediate step in the manufacturing method of the third example of the first-1 embodiment of the RFID tag mounting component of the present invention. Figure 11 This is a front cross-sectional view showing the final step of the manufacturing method of the third example of the first-1 embodiment of the RFID tag mounting component of the present invention.

[0057] like Figure 8 As shown, in the third example of the first embodiment of the bolt with RFID tag, the surface of the base portion 1-12 of the shaft portion 1-1 is formed to be flat, and the pedestal portion 1-21 is formed to be cuboid in shape. The pedestal portion 1-21 may also be formed to be cubic in shape. In short, no lower portion is formed on the top surface of the pedestal portion 1-21. The width of the pedestal portion 1-21 is smaller than the outer shape of the base portion 12; in other words, the surface of the base portion 1-12 extends beyond the pedestal portion 1-21. The reinforcing antenna 1-4 is also formed in a helical spring shape, similar to the first example.

[0058] like Figure 9 As shown, in the intermediate process of the third example of the first embodiment of manufacturing a bolt with an RFID tag, the base portion 1-21 is fixed to the base portion 1-12 of the shaft portion 1-1 using an adhesive or the like. An RFID tag 1-3 is fixed to the top surface of the base portion 1-21 using an adhesive or the like. Furthermore, although not shown, in the third example of the bolt with an RFID tag in the first embodiment, a lower portion may also be formed on the surface of the base portion 1-21, and an RFID tag may be embedded in this lower portion.

[0059] like Figure 10 As shown, in the intermediate process of the third example of the first embodiment of manufacturing the bolt with RFID tag, the reinforcing antenna 1-4 is further disposed on the base portion 1-12 in such a way that it surrounds the pedestal portion 1-21. Regarding the reinforcing antenna 1-4, the base end is fixed to the pedestal portion 1-21, the middle portion surrounds the RFID tag 1-3, and the front end extends beyond the top surface of the pedestal portion 1-21.

[0060] like Figure 11As shown, in the final step of the third example of the first embodiment of manufacturing the bolt with RFID tags, the base portion 1-21 and the base portion 1-12, which are equipped with RFID tags 1-3, are molded with resin to form a cap portion 1-22. That is, in the final step, a head 1-2 is formed by molding the base portion 1-21 with the cap portion 1-22. Regarding this bolt with RFID tags, if the head 1-2 rotates circumferentially, the shaft portion 1-1 will not rotate freely but will rotate integrally.

[0061] Next, while referring to Figures 12 to 14 The manufacturing method of the fourth example of the first embodiment of the bolt with RFID tag will be described in three parts: initial process, intermediate process and final process. Figure 12 This is a front cross-sectional view showing the initial step of the manufacturing method of the fourth example of the first-1 embodiment of the RFID tag mounting component of the present invention. Figure 13 This is a cross-sectional front view of an intermediate step in the manufacturing method of the fourth example of the first-1 embodiment of the RFID tag mounting component of the present invention. Figure 14 This is a front cross-sectional view showing the final step of the manufacturing method of the fourth example of the first-1 embodiment of the RFID tag mounting component of the present invention.

[0062] like Figure 12 As shown, in the manufacturing method of the fourth example of the first embodiment, in the initial process, a protrusion 1-123 is formed at the center of the surface side of the base plate 1-12. Moreover, in the initial process, the enhancement antenna 1-4 is disposed on the base plate 1-12 such that the base end side half of the enhancement antenna 1-4 surrounds the protrusion 1-123 of the base plate 1-12.

[0063] like Figure 13 As shown, in the intermediate step of the manufacturing method of the fourth example of the first embodiment, a base plate portion 1-12 of the shaft-shaped portion 1-1 is provided in the cavity of a mold, and a prototype 1-20 having a pedestal portion 1-21 is formed by molding molten resin. A longitudinal hole portion 1-201 is formed on the top of the prototype 1-20 of the head. Therefore, the mold used in the intermediate step of the manufacturing method of the fourth example of the first embodiment has a first core for forming the longitudinal hole portion 1-201. However, the longitudinal hole portion 1-201 can also be formed using a drill bit or the like. In summary, in the intermediate step, the reinforcing antenna 1-4, which is provided on the pedestal portion 1-21 of the prototype 1-20 of the head, is sealed with molten resin.

[0064] like Figure 14As shown, in the final step of the manufacturing method of the fourth example of the first embodiment, RFID tags 1-3 are fitted deep into the longitudinal hole 201 of the prototype 20 of the head. Next, using the second core of the mold, molten resin is injected into the longitudinal hole of the prototype 1-20 of the head, into which the RFID tags 1-3 are fitted. Therefore, the mold used in the final step of the third manufacturing method has a second core for forming the longitudinal hole 1-201. After the molten resin 1-202 solidifies, it becomes integral with the prototype 1-20 of the head, and the final head 1-2 is completed.

[0065] Alternatively, instead of using the second core and injecting molten resin into the longitudinal hole 1-201, a resin plug can be separately manufactured and embedded in the longitudinal hole 1-201. The resin plug is fixed with an adhesive to maintain its embedded state in the longitudinal hole of the prototype 1-20 with the RFID tag 1-3 mounted on it. Since the plug cannot rotate or twist, it is fixed to the prototype 1-20 of the head in a way that prevents it from detaching from the longitudinal hole 1-201.

[0066] Next, while referring to Figure 15 The fifth example of the first-1 embodiment of the mounting component with RFID tag is described. Figure 15 This is a front cross-sectional view showing the fifth example of the first-1 embodiment of the RFID tag mounting component of the present invention.

[0067] The fifth example of the first-1 embodiment of the mounting component with RFID tag, like the first to fourth examples of the first-1 embodiments, includes a shaft-shaped portion 1-1, a head 1-2, an RFID tag 1-3, and a reinforcing antenna 1-4. However, as... Figure 15 As shown, the enhancement antenna 1-4 of the fifth example of the first-1 embodiment is formed in the shape of a conical helical spring. The enhancement antenna 1-4 of the fifth example of the first-1 embodiment has a reduced diameter at the base end and an expanded diameter at the front end of the base plate portion 1-12. Therefore, the head 1-2 of the first example of the first-2 embodiment is set as a truncated cone with a reduced diameter at the base plate portion 1-12 and an expanded diameter at the front end. Furthermore, a protrusion 1-123 protrudes from the surface of the base plate portion 1-12. An RFID tag 1-3 is mounted on the top surface of the protrusion 1-123.

[0068] The cap portion 1-22 is molded from resin using the base portion 1-12 and protrusion 1-123 of the shaft portion 1-1, as well as the tag module (RFID tag 1-3 and reinforcing antenna 1-4). Since the reinforcing antenna 1-4 is shaped like a cylindrical helical spring with an expanded front end, the cap portion 1-22 is formed as a truncated frustum with an expanded front end along the outer periphery of the reinforcing antenna 1-4. The cap portion 1-22 is formed using a mold insert. Knurling, such as straight lines, can also be formed along the length of the outer peripheral surface of the cap portion 1-22.

[0069] In the fifth example of the first-1 embodiment, the enhancement antenna 1-4 is configured such that the side with the reduced diameter surrounds the RFID tag 1-3. That is, because the base portion 12 of the enhancement antenna 1-4 has a reduced diameter, the protrusion 1-123 is formed low. Adjustments are made according to the shape of the enhancement antenna 1-4 to correspond to the desired sensitivity characteristics.

[0070] Next, while referring to Figure 16 The sixth example of the first-1 embodiment of the mounting component with RFID tag is described. Figure 16 This is a front cross-sectional view showing the sixth example of the first-1 embodiment of the RFID tag mounting component of the present invention.

[0071] like Figure 16 As shown, in the sixth example of the first-1 embodiment, the enhancement antenna 1-4 has an expanded diameter at the base end of the base portion 1-12 and a reduced diameter at the front end. An RFID tag 1-3 is mounted on the top surface of the protrusion 1-123 protruding from the base portion 1-12. The RFID tag 1-3 is disposed on the reduced diameter front end of the enhancement antenna 1-4. In the sixth example of the first-1 embodiment, because the front end of the enhancement antenna 1-4 is reduced in diameter, the protrusion 1-123 is formed to be high. Based on this shape of the enhancement antenna 1-4, adjustments are made accordingly to achieve the desired sensitivity characteristics.

[0072] The cap portion 1-22 is molded into a truncated frustum shape with a reduced front diameter by sealing the base portion 1-12, protrusion 1-123, and tag module (RFID tag 1-3 and reinforcing antenna 1-4) with resin. Since the reinforcing antenna 1-4 is formed in the shape of a conical helical spring, the cap portion 1-22 is formed into a truncated cone shape along the outer periphery of the reinforcing antenna 1-4. The cap portion 1-22 is formed by a mold insert. Knurling, resembling straight lines, is formed on the outer peripheral surface of the cap portion 1-22 along its length.

[0073] Although not illustrated, in the seventh example of the first-1 embodiment, an RFID tag 1-3 is disposed on the base end side of the cylindrical helical spring-shaped reinforcing antenna 1-4 shown in the first example. Therefore, the protrusion 1-123 of the base portion 1-12 on which the RFID tag 1-3 is mounted is formed more... Figures 1 to 4 The protrusions shown are 1-123 low. Or, Figure 13 and Figure 14 The longitudinal hole 1-201 shown is formed deep.

[0074] Although not illustrated, in the eighth example of the first-1 embodiment, an RFID tag 1-3 is disposed on the front end side of the cylindrical helical spring-shaped reinforcing antenna 1-4 shown in the first example. Therefore, the protrusion 1-123 of the base portion 1-12 on which the RFID tag 1-3 is mounted is formed more... Figures 1 to 4 The protrusion 1-123 shown is high. The RFID tag 1-3 mounted on such a protrusion 1-123 is far away from the base plate portion 1-12 of the shaft portion 1-1, and is therefore less affected by the base plate portion 1-12 of the shaft portion 1-1, thus improving performance.

[0075] The RFID-tagged bolts of the first-1 embodiment described above (and the RFID-tagged bolts of the first-2 embodiments described below) are also used in various fields where data sent from a reader is written into RFID tags 1-3. For example, RFID-tagged bolts are used in mold management systems. Molds managed in mold management systems (hereinafter referred to as "managed molds") can be stored for, for example, 15 years or more after the product production is completed.

[0076] In addition, the bolt with the RFID tag has an enhanced antenna 1-4, so that even if the RFID tag 1-3 is a passive type that transmits and receives weak radio waves, the radio waves will be enhanced, which can improve the radial directivity and reliably transmit and receive radio waves with the reader.

[0077] [Implementation Method 1-2] While referring to Figure 17A and Figure 17B The first example of the first and second embodiments of the mounting component with RFID tag of the present invention will be described. Figure 17A This is a partial cross-sectional top view showing a first example of the first-second embodiment of the mounting component with RFID tag of the present invention. Figure 17B This is a front cross-sectional view showing a first example of the first-second embodiment of the mounting component with RFID tag of the present invention.

[0078] like Figure 17A and Figure 17BAs shown, the RFID tag mounting component of the first example of the first-2 embodiments is similar to that of the first-1 embodiment, including a shaft-shaped portion 1-1, a head 1-2, an RFID tag 1-3, and an enhancement antenna 1-4. However, the RFID tag mounting component of the first example of the first-2 embodiments includes a head 1-2 having a plate-shaped rib 1-24 that protrudes radially toward the insertion portion 1-11.

[0079] The head 1-2 has a deformed cylindrical central portion 1-23 surrounding the base portion 1-12 and a pair of plate-shaped ribs 1-24. The central portion 1-23 is designed to be integrally formed from the cylindrical portion and the frustum-shaped portion along the axial direction. Each of the pair of ribs 1-24 protrudes radially from the central portion 1-23 like a wing screw. Each rib 1-24 has a bottom edge portion 1-241 orthogonal to the axial direction of the insertion portion 1-11, and an inclined portion 1-242 that protrudes from the central portion 1-23 inclined relative to the axial direction of the insertion portion 1-11.

[0080] The reinforcing antenna 1-4, corresponding to the shape of the butterfly screw-shaped head 1-2, is patterned within the head 1-2 in a meandering conductor pattern. When the length direction of the insertion portion 1-11 is set as the width direction, this meandering conductor pattern is formed such that its width is narrow at the base end side of the ribs 1-24 and gradually widens at the front end side. The base end of each meandering conductor pattern within each rib 1-24 is close to the RFID tag. That is, the reinforcing antenna 1-4 is not electrically connected to the RFID tag 1-3. The reinforcing antenna 1-4 with the meandering conductor pattern simultaneously possesses both magnetic field coupling and capacitive coupling functions.

[0081] also, Figure 17A and Figure 17B The reinforcement antenna 1-4 shown is configured as a meandering conductor pattern that gradually widens at the front end. However, the reinforcement antenna 1-4 can also be configured as a meandering conductor pattern of the same width along its entire length. In this case, the bottom and top edges of the ribs 1-24 are formed parallel to each other.

[0082] Here, while referring to Figures 18A to 18C The first manufacturing method of the bolt with RFID tag in the first example of the first embodiment of the first and second embodiments will be described in three steps: initial process, intermediate process and final process. Figure 18A This is the first example of the first-second embodiment of the mounting component with RFID tag of the present invention, and is a cross-sectional front view showing the initial step of the first manufacturing method. Figure 18B This is the first example of the first-second embodiment of the mounting component with RFID tag of the present invention, and is a cross-sectional front view showing an intermediate step of the first manufacturing method. Figure 18CThis is the first example of the first-second embodiment of the RFID tag mounting component of the present invention, and is a cross-sectional front view showing the final step of the first manufacturing method.

[0083] The head 1-2 of the bolt with the RFID tag has a meandering conductive pattern, and therefore it is formed using a mold designed for in-mold processing in a horizontal position. Figure 18A As shown, in the first manufacturing method of the bolt with RFID tag in the first example of the first embodiment of the first-second embodiment, a one-sided half of the head 1-200 is formed in the thickness direction of the head 1-2 by in-mold semi-forming. A frame is formed on the outer periphery of the half of the head 1-200, and a flat recess 1-210 is formed on the inner side of the frame.

[0084] Next, as Figure 18B As shown, a wavy conductor pattern of reinforcement antenna 1-4 and RFID tag 1-3 is disposed within a recess 1-210 formed on one side half of the head 1-2. Since a frame is formed on the outer periphery of the lower half of the head 1-2, the reinforcement antenna 1-4 will not be misaligned from the recess 1-210.

[0085] Next, as Figure 18C As shown, by replacing the mold with a different molding cavity, molten resin is molded in the recess 1-210 where the reinforcing antenna 1-4 and RFID tag 1-3 are provided, forming the other half of the head, thereby molding the head 1-2. The bolt with the RFID tag and such head 1-2 can be turned by the rib 1-24, which can tighten or loosen, thus improving usability based on sensitivity.

[0086] Here, while referring to Figures 19A to 19C The second manufacturing method of the bolt with RFID tag in the first example of the first and second embodiments will be described in three steps: initial process, intermediate process and final process. Figure 19A This is a first example of the first-second embodiment of the RFID tag mounting component of the present invention, and is a front view showing the initial step of the second manufacturing method. Figure 19B This is the first example of the first-second embodiment of the RFID tag mounting component of the present invention, and is a front view showing an intermediate step of the first-second manufacturing method. Figure 19C This is the first example of the first-second embodiment of the RFID tag mounting component of the present invention, and is a cross-sectional front view showing the final step of the second manufacturing method.

[0087] In the second manufacturing method of the bolt with RFID tag in the first example of the first-second embodiment, an enhanced antenna 1-4 with a meandering conductor pattern and an RFID tag 1-3 are used to install an insert in a substrate filling material (gasket (web)) such as a seal.

[0088] like Figure 19A As shown, in the initial step of the second manufacturing method of the bolt with RFID tag in the first example of the first embodiment of the first-second embodiment, one half of the head 1-200 having a positioning protrusion 1-25 for positioning the insert is molded in-mold.

[0089] Next, as Figure 19B As shown, in the intermediate process, a gasket is placed on the head 1-2, which is half-formed in the mold. The gasket is positioned at a specified location by a positioning protrusion 1-25.

[0090] Next, as Figure 19C As shown, in the final process, the mold cavity is changed to form the other half of the head 1-2, forming the head 1-2 of the specified shape.

[0091] Next, while referring to Figures 20A to 20C The following describes a second example of the first and second embodiments of the RFID tag mounting component of the present invention. Figure 20A This is the second example of the first and second embodiments of the RFID tag-equipped mounting component of the present invention, and represents the final process. Figure 20C A top view of the AA-line cross section. Figure 20B This is the second example of the first and second embodiments of the RFID tag-equipped mounting component of the present invention, and represents the final process. Figure 20C BB line section view. Figure 20C This is the second example of the first and second embodiments of the RFID tag mounting component of the present invention, and is a second cross-sectional front view showing the final process.

[0092] like Figures 20A to 20C As shown, the RFID tag mounting component of the second example of the first-second embodiment is similar to that of the first-first embodiment, including a shaft-shaped portion 1-1, a head 1-2, an RFID tag 1-3, and an enhancement antenna 1-4. However, the RFID tag mounting component of the second example of the first-second embodiment has a rectangular plate-shaped head 1-2 that protrudes radially toward the insertion portion 1-11.

[0093] The second example of the first-second embodiment has a head 1-2 comprising a deformed cylindrical central portion 1-23 surrounding the base portion 1-12 and rectangular plate-shaped ribs 1-24. The central portion 1-23 is configured to be integrally formed by the cylindrical portion and the frustum-shaped portion along the axial direction. The lower and upper edges of the ribs 1-24 are formed parallel to each other.

[0094] The second example of the first-second embodiment of the enhancement antenna 1-4 is configured to be U-shaped when viewed from the front, having two parallel strip-shaped portions 1-42 and a folded-back portion 1-43 connecting one end of the two strip-shaped portions 1-42. The center portion 1-23 of the strip-shaped portion 1-42 on the axial portion 1-1 side of the enhancement antenna 1-4 is fixed to the frustum-shaped portion of the head 1-2. The U-shaped conductor pattern enhancement antenna 1-4 has both magnetic field coupling and capacitive coupling functions.

[0095] RFID tags 1-3 are sandwiched between two strips 1-42 in a manner that is located within ribs 1-24. Figures 20A to 20C Although the RFID tag 1-3 shown is positioned close to the folded-back portion 1-43 of the reinforcing antenna 1-4, it could also be positioned on the front end. The RFID tag 1-3 is not positioned in the center of the head 1-2, but rather within a rib 1-24. Alternatively, although not illustrated, the RFID tag 1-3 could also be positioned within the head 1-2, not within the rib 1-24. That is, the placement location of the RFID tag 1-3 is not limited.

[0096] Although not illustrated, regarding the RFID tag mounting component of the second example of the first and second embodiments, the RFID tag 1-3 can also be configured as a multi-fold (multiple) zigzag pattern, or in other words, a horizontally meandering pattern, in which multiple strip-shaped portions 1-42 are arranged side by side. In this case, the RFID tag 1-3 is sandwiched between an adjacent strip-shaped portion 1-42. Furthermore, the rib 1-24 molded from the multi-fold zigzag reinforcing antenna 1-4 is formed to be higher than the rib 1-24 molded from the U-shaped reinforcing antenna 1-4.

[0097] The second example of the mounting component with RFID tag in the first-second embodiment is manufactured in the same manner as the first example of the mounting component with RFID tag in the first-second embodiment.

[0098] Next, while referring to Figure 21A and Figure 21B A third example of the first and second embodiments of the RFID tag mounting component of the present invention will be described. Figure 21A This is a third example of the first and second embodiments of the RFID tag mounting component of the present invention, and is a partial cross-sectional top view showing the final process. Figure 21B This is a third example of the first and second embodiments of the RFID tag mounting component of the present invention, and is a cross-sectional front view showing the final process.

[0099] As shown in Figure 21, the RFID tag mounting component of the third example of the first-2 embodiments is similar to that of the first-1 embodiment, including a shaft-shaped portion 1-1, a head 1-2, an RFID tag 1-3, and an enhancement antenna 1-4. However, the RFID tag mounting component of the second example of the first-2 embodiments includes a rectangular plate-shaped head 1-2 that protrudes radially into the insertion portion 1-11.

[0100] The head 1-2 of the third embodiment of the first-second example has a deformed cylindrical central portion 1-23 surrounding the base portion 1-12 and rectangular plate-shaped ribs 1-24. The central portion 1-23 is configured to be integrally formed by the cylindrical portion and the frustum-shaped portion along the axial direction. The lower and upper edges of the ribs 1-24 are formed parallel to each other. However, the ribs 1-24 in this third example are formed to be thicker than the ribs 1-24 in the second example.

[0101] The third example of the first and second embodiments shows that the enhancement antenna 1-4 is a component folded in half with one side of the strip portions 1-42 facing each other. The strip portions 1-42 are rectangular in shape with a long side and a short side, with the crease located on the short side and disposed within one end of the rib 1-24. The front ends of the opposing strip portions 1-42 of the enhancement antenna 1-4 are disposed within the other end of the rib 1-24. The enhanced antenna 1-4 with the conductor pattern of the folded component simultaneously possesses both magnetic field coupling and capacitive coupling functions. Furthermore, if the crease of the folded enhancement antenna 1-4 is located on the long side, the communication distance will be significantly shortened.

[0102] The RFID tag 1-3 is clipped between the two strip-shaped portions 1-42 of the reinforcing antenna 1-4 of the folded component. As shown in Figure 21, the RFID tag 1-3 is positioned near the center portion 1-23 of the reinforcing antenna 1-4. However, the RFID tag 1-3 can also be positioned near the folded portion 1-43. In summary, the RFID tag 1-3 is not positioned at the center of the head 1-2, but rather at the rib 1-24.

[0103] The third example of the first-second embodiment of the mounting component with RFID tag is manufactured in the same manner as the first example of the first-second embodiment of the mounting component with RFID tag.

[0104] Regarding the RFID tags 1-3 in the first to third examples of the first and second embodiments, the reinforcing antenna 1-4 is configured as a strip. Thus, if it expands as it moves away from the RFID tag 1-3, the radiation area widens; if it shrinks, the radiation area is concentrated, and the communication distance is extended. In addition, by changing the shape of the reinforcing antenna 1-4, the perceived size of the head 1-2 can be changed.

[0105] [Other embodiments of the first embodiment] The embodiments of the RFID-tagged bolts of the present invention are not limited to the above description, and include modifications or improvements made within the scope of achieving the purpose of the present invention.

[0106] For example, in the above embodiment, the insertion part 1-11 is assumed to be a shaft with external threads. However, the insertion part 1-11 may also be a pin without external threads, and the pin is not limited to a cylindrical shape, but may also be prismatic.

[0107] Furthermore, in the above embodiment, the base plate portion 1-12 is formed in a disc shape. However, the base plate portion 1-12 may also be polygonal. Additionally, in the above embodiment, the outer peripheral surface of the base plate portion 1-12 has a chamfered portion 1-121, and the head 1-2 has a locking portion that engages with the chamfered portion 1-121. However, the outer peripheral surface of the base plate portion 1-12 may not have the chamfered portion 1-121 formed, but may instead be knurled, with the inner surface of the head 1-2 entering the knurling. Furthermore, when the base plate portion 1-12 and the head 1-2 are fixed as one unit, the chamfered portion 1-121 may not be formed on the base plate portion 1-12, and the head 1-2 may not have a locking portion.

[0108] Furthermore, in the above embodiment, the insertion portion 1-11 and the base plate portion 1-12 are made of metal. However, one or both of the insertion portion 1-11 and the base plate portion 1-12 may also be made of resin.

[0109] Furthermore, the above embodiments described the use of RFID-tagged bolts in the management of managed molds. However, RFID-tagged bolts can also be used in logistics, railways, and the food service industry. In logistics, they are screwed into the main body of trucks or containers to manage the flow of goods. In the railway industry, they are used to manage the loosening of bolts. Regarding these bolts, there are instances where larger bolts are used compared to those screwed into managed molds. In the food service industry, in conveyor belt sushi restaurants, RFID-tagged bolts can be installed on plates to manage the elapsed time of sushi on the plates or to deliver directly to individual customers who have placed orders.

[0110] [Implementation Method 2-1] While referring to Figure 22 and Figure 23 The first example of the second-first embodiment of the mounting component with RFID tag of the present invention will be described. Figure 22 This is a front cross-sectional view showing the head of the RFID tag mounting component and the RFID tag assembly unit of the second-first embodiment of the present invention. Figure 23 This is a front cross-sectional view showing the first example of the second-first embodiment of the mounting component with RFID tag of the present invention.

[0111] The RFID-tagged mounting component includes not only fastening components such as bolts or screws that engage with internal threads or nuts, but also pins that are inserted into shaft holes. However, the RFID-tagged mounting component in Embodiment 2-1 (and similarly in Embodiments 2-2 to 2-4 described later) uses a bolt-like mounting component as an example, so it will be mainly described below as a "bolt with an RFID tag". Figure 22 As shown, the bolt with the RFID tag has an RFID (Radio Frequency Identification) tag assembly unit 2-1 and a head 2-2.

[0112] The RFID tag assembly unit 2-1 includes a shaft-shaped portion 2-11, a base portion 2-12, and an RFID tag 2-13. The shaft-shaped portion 2-11 has an insertion portion 2-111 and a base portion 2-112. Both the insertion portion 2-111 and the base portion 2-112 are formed of a metal such as aluminum or stainless steel. The insertion portion 2-111 is shaft-shaped and has external threads. However, no external threads are formed near one end of the insertion portion 2-111 (the portion continuous with the base portion 2-112).

[0113] The base plate portion 2-112 protrudes in the cross-sectional direction from one end of the insertion portion 2-111. The cross-sectional direction is orthogonal to the length direction of the insertion portion 2-111. The cross-sectional direction of the insertion portion 2-111, which has external threads, can also be referred to as the radial or width direction. The base plate portion 2-112 is formed in a disc shape. The center of the disc-shaped base plate portion 2-112 coincides with the center in the cross-sectional direction of the insertion portion 2-111. A flat cut surface 2-112a is formed on a portion of the outer peripheral surface of the base plate portion 2-112.

[0114] The pedestal portion 2-12 is formed by a resin insert on the surface side (upper side in the drawing) of the base portion 2-112 where the insertion portion 111 is not present. Figure 22 As shown, the pedestal portion 2-12 has an expansion portion 2-121 and a protrusion portion 2-122.

[0115] The expansion portion 2-121 is formed in the shape of a disc with an annular portion surrounding the outer periphery of the base portion 2-112. The expansion portion 2-121 is inserted into the base portion 2-112 and integrated in a manner that prevents it from separating from the base portion 2-112. An arc-shaped locking portion (not shown) is formed on a portion of the inner surface of the expansion portion 2-121 in a manner that engages with the cut surface 2-112a of the base portion 2-112. The protrusion 2-122 protrudes from the center of the surface of the base portion 2-112 in a direction opposite to that of the insertion portion 2-111 in a polygonal or cylindrical shape. By forming the protrusion 2-122 in a polygonal shape, or by providing the arc-shaped locking portion on the cylindrical protrusion 2-122, it is possible to prevent the protrusion 2-122 from spinning freely relative to the head 2-2.

[0116] An insert portion 2-122a is formed at the top of the protrusion 2-122, into which an RFID tag 2-13 is embedded. The RFID tag 2-13 is thus protected by being embedded in the top of the protrusion 2-122 formed by the insert. However, the RFID tag 2-13 may not be embedded in the insert portion 2-122a, but may be fixed to the top surface of the protrusion 2-122 using an adhesive or the like, leaving the RFID tag 2-13 exposed. Alternatively, a recessed lower portion may be formed on the top surface of the protrusion 2-122, and the RFID tag 2-13 may be embedded in this lower portion. Furthermore, the RFID tag 2-13 embedded in the lower portion may also be fixed using an adhesive or the like.

[0117] In summary, RFID tag 2-13 is a passive tag. That is, RFID tag 2-13 does not have a built-in battery, but receives radio waves from a reader (not shown) and uses those radio waves as its power source. RFID tag 2-13 is an ultra-small (e.g., 2.5mm x 2.5mm x 0.375mm) sheet-like electronic component that combines an IC chip for recording information and an antenna for wireless communication.

[0118] In the first example of the second-1 embodiment, the head 2-2 includes a cap 2-21 covering the protrusion 2-122 of the base portion 2-12, and an enhancement antenna 2-221 built into the cap 2-21. The head 2-2 and the base portion 2-12 are separately molded from each other by resin and are designed to be detachable.

[0119] The head 2-2 protrudes towards the surface of the base portion 2-112 and has the same outer diameter as the expansion portion 2-121 of the pedestal portion 2-12. Regarding the head 2-2, a cap 2-21 is formed using a mold insert. The cap 2-21 is formed as a one-end-sealing cylindrical shape with a thick sealing portion on one end side (the upper side in the drawing). The one-end-sealing cylindrical cap 2-21 can be formed as a one-end-sealing cylindrical shape or a one-end-sealing prismatic cylindrical shape, etc. (this is also true in the following embodiments). Although not shown, knurling such as straight lines can also be formed along the length direction on the outer peripheral surface of the cap 2-21.

[0120] On the head 2-2, a recessed portion 2-211 is formed at the center of the base end side (lower side in the attached drawing) of the cap 2-21, into which the protrusion 2-122 of the pedestal portion 2-12 is inserted. The recessed portion 2-211 is shaped to allow the protrusion 2-122 to be inserted. That is, if the protrusion 2-122 is cylindrical, the recessed portion 2-211 is shaped like a prism. If the protrusion 2-122 is cylindrical, the recessed portion 2-211 is shaped like a cylinder. A helical spring-shaped reinforcing antenna 2-221 is built into the cap 2-21. The base end side of the reinforcing antenna 2-221 is positioned between the recessed portion 2-211 and the outer side surface.

[0121] The enhancement antenna 2-221 amplifies the radio waves transmitted and received by the RFID tag 2-13. The enhancement antenna 2-221 is formed from a wire containing metal or the like, shaped like a cylindrical helical spring. For example... Figure 23 As shown, the length of the protrusion 2-122 is preferably more than half the length of the reinforcing antenna 2-221. The base end of the reinforcing antenna 2-22 is fixed to the surface of the expansion portion 2-121, with half of the base end side surrounding the protrusion 2-122 and half of the front end side extending beyond the top surface of the protrusion 2-122. An RFID tag 2-13 is disposed within the middle portion along the length of the reinforcing antenna 2-221. The reinforcing antenna 2-221 is not electrically connected to the RFID tag 2-13. The reinforcing antenna 2-221 is coupled to the antenna magnetic field contained in the RFID tag 2-13.

[0122] Next, while referring to Figure 24 and Figure 25 The second example of the second embodiment of the second-1 describes a bolt with an RFID tag. Figure 24 This is a front cross-sectional view showing the head of the RFID tag mounting component and the RFID tag assembly unit of the second embodiment of the present invention. Figure 25 This is a front cross-sectional view showing a second example of the second-1st embodiment of the mounting component with an RFID tag according to the present invention.

[0123] The RFID tag assembly unit 2-1 of the second embodiment of the 2-1 includes the same shaft-shaped part 2-11, pedestal part 2-12, and RFID tag 2-13 as the first embodiment of the 2-1.

[0124] In the second example of the second embodiment 2-1, the cap 2-21 is configured as a cylindrical end-sealing structure with an outer diameter larger than the expansion portion 2-121 of the base portion 2-12. That is, the expansion portion 2-121 is externally fitted into the base end of the cap 2-21. Therefore, a layer difference hole 2-212 for the expansion portion 2-121 to be inserted is formed on the cap 2-21 at the base end side of the recessed portion 2-211 into which the protrusion 2-122 is inserted.

[0125] Although not illustrated, the bolt with the RFID tag in Embodiment 2-1 is available in various types besides those in Embodiments 1 and 2. For example, there is a type where the RFID tag 2-13 is positioned on the front or base side of the reinforcing antenna 2-221 by making the protrusion of the base portion 2-12 higher or lower than that in Embodiments 1 and 2. Alternatively, the reinforcing antenna 2-221 may not be cylindrical but rather a conical helical spring shape with a reduced diameter on the front or base side and an expanded diameter on the base or front side. In this case, the cap 2-21 is truncated conical in shape, corresponding to the shape of the reinforcing antenna 2-221.

[0126] In this second-1 embodiment, the head 2-2 with the enhanced antenna 2-221 is appropriately selected from various types according to the sensitivity of the RFID tag 2-13, and is attached and detached relative to the pedestal portion 2-12. The pedestal portion 2-12 is exposed before the head 2-2 is installed. The RFID tag 2-13 embedded in the top part of the protrusion 2-122 of the pedestal portion 2-12 is less susceptible to damage. The cap 2-21 installed on the pedestal portion 2-12 is inserted into the protrusion 2-122 of the pedestal portion 2-12 within the recess 2-211. In the second example, the expansion portion 2-121 of the pedestal portion 2-12 is embedded within the layer difference hole 2-212. When the head 2-2 is fully installed on the pedestal portion 2-12, the base end face of the head 2-2 overlaps with the surface of the expansion portion 2-121 of the pedestal portion 2-12.

[0127] The RFID-tagged bolts of embodiment 2-1 are used in various fields, such as where data sent from a reader is written into RFID tags 2-13. For example, RFID-tagged bolts are used in mold management systems. Molds managed in mold management systems (hereinafter referred to as "managed molds") can be stored, for example, for more than 15 years after the product production is completed.

[0128] In addition, the bolt with the RFID tag has an enhanced antenna 2-221, so that even if the RFID tag 2-13 is a passive type that transmits and receives weak radio waves, the radio waves will be enhanced, and the directivity in the cross-sectional direction can be improved to reliably transmit and receive radio waves with the reader.

[0129] The RFID-tagged bolt is designed with replaceable heads 2-2, allowing for selection of the optimal type of head 2-2 based on the installation conditions. For example, when it is desired to securely mount the head 2-2 to the base portion 2-12, the second type of head 2-2 is selected, where not only the protrusion 2-122 is inserted into the recess 2-211, but the base portion 2-112 is also embedded in the interlayer hole portion 2-212. Furthermore, the first type of head 2-2 is installed on RFID-tagged bolts intended for installation in confined spaces, while the second type of head 2-2 is installed on RFID-tagged bolts intended for installation in spacious areas.

[0130] [Implementation Method 2-2] While referring to Figure 26 and Figure 27 The second-second embodiment of the RFID tag mounting component of the present invention will be described below. Figure 26 This is an exploded perspective view showing the head of the RFID tag mounting component and the RFID tag assembly unit of the second-second embodiment of the present invention. Figure 27 This is a front cross-sectional view showing the second-second embodiment of the RFID tag mounting component of the present invention.

[0131] like Figure 26 As shown, the bolt with an RFID tag in the second-2 embodiment includes an RFID tag assembly unit 2-1 and a head 2-2. The RFID tag assembly unit 2-1 includes a shaft-shaped portion 2-11, a base portion 2-12, and an RFID tag 2-13, which are the same as in the second-1 embodiment.

[0132] The head 2-2 has a cap 2-21 covering the main part of the pedestal part 2-12 on which the RFID tag 2-13 is mounted on the top surface, and an enhancement antenna 2-222. The head 2-2 is separately formed from the pedestal part 2-12 and is designed to be detachable.

[0133] The head 2-2 of the RFID tag mounting component in embodiment 2-2 differs from that in embodiment 2-1, having a cylindrical cap 2-21 with one end sealed and a pair of plate-shaped ribs 2-23 extending in opposite directions from the side of the cap 2-21. The ribs 2-23 protrude in the cross-sectional direction (radial in the drawing) with a width approximately the same as the axial length (height in the drawing) of the cap 2-21. The ribs 2-23 of the cap 2-21 are accessible to fingers. By forming the ribs 2-23 as wide plates, they are less prone to bending than when formed as shafts, and the head 2-2 can be easily rotated without digging into fingers. However, the ribs 2-23 could also be formed as shafts. A recessed portion 2-211 in the shape of a prism-shaped protrusion 2-122 of the base portion 2-12 is formed on the cap 2-21.

[0134] An RFID tag 2-13 is embedded in the top portion of the protrusion 2-122. The RFID tag 2-13 is sandwiched between the deep inner surface of the recess 2-211 of the cap 2-21 and the top surface of the protrusion 2-122. Alternatively, the protrusion 2-122 may be cylindrical and the recess 2-211 may be cylindrical. In this case, knurling, or engaging cut surfaces and locking portions are formed on the overlapping surfaces of the protrusion 2-122 and the recess 2-211.

[0135] The enhanced antenna 2-222 includes an element that integrates the annular portion 2-222a and the linear portion 2-222b. The annular portion 2-222a is embedded in the cap 2-21 in such a way that it surrounds the front end side of the recessed portion 2-211. The annular portion 2-222a shown in the figure is formed as a ring with only one and a half loops. The head (not shown) has the annular portion 2-222a, which is formed as a ring with more than two and a half loops, embedded in the cap 2-21.

[0136] In any of the enhancement antennas 2-222, each end of the diameter of the annular portion 2-222a is continuous with the straight portion 2-222b. Two straight portions 2-222b are formed in an axial shape and are embedded within each rib 2-23. When the rib 2-23 is formed as a plate, the straight portion 2-222b is positioned on one end edge of the rib 2-23 (the upper end in the attached figure). The two straight portions 2-222b and the RFID tag 2-13 are arranged in a straight line. Therefore, regarding the annular portion 2-222a connected to the straight portion 2-222b, the connection position with the straight portion 2-222b is at the same height, forming an overall inclined annular shape.

[0137] Regarding the head 2-2 of the second-2 embodiment, there are various types with built-in enhancement antennas 2-222. The enhancement antennas 2-222 are formed in various forms, with different numbers of turns in the annular portion 2-222a and different lengths in the straight portion 2-222b. The head 2-2 is appropriately selected according to the radio waves transmitted and received by the RFID tag 2-13 and mounted on the base portion 2-12. That is, by inserting the protrusion 2-122 of the base portion 2-12 into the recess 2-211 of the cap 21, the head 2-2 becomes an integrated unit of the base portion 2-12 and the cap 2-21. Figure 27 As shown, the head 2-2 is in a state where the RFID tag 2-13 mounted on the protrusion 2-122 of the base portion 2-12 is surrounded by the annular portion 2-222a of the enhancement antenna 2-222.

[0138] The bolt with RFID tag in the second-2nd embodiment has an enhanced antenna 2-222 that integrates the annular portion 2-222a and the linear portion 2-222b. As a result, even if the RFID tag 2-13 is a passive type that transmits and receives weak radio waves, the radio waves will be enhanced, and the directivity in the cross-sectional direction can be improved to reliably transmit and receive radio waves with the reader.

[0139] [Second and Third Embodiments] While referring to Figure 28 and Figure 29 While describing the first example of the second and third embodiments of the RFID tag mounting component of the present invention, refer to Figure 30 and Figure 31 The second example of the second-third implementation method will be explained. Figure 28 This is a front cross-sectional view showing the head of the RFID tag mounting component and the RFID tag assembly unit of the second and third embodiments of the present invention, as well as the first example. Figure 29 This is a front cross-sectional view showing the first example of the second-third embodiment of the mounting component with RFID tag of the present invention. Figure 30 This is a front cross-sectional view showing the head of the RFID tag mounting component and the RFID tag assembly unit of the second-third embodiment of the present invention. Figure 31 This is a front cross-sectional view showing a second example of the second-third embodiment of the mounting component with an RFID tag according to the present invention.

[0140] like Figures 28 to 31 As shown, the bolts with RFID tags in the first and second examples of the second and third embodiments include an RFID tag assembly unit 2-1 and a head 2-2. The RFID tag assembly unit 2-1 includes a shaft-shaped portion 2-11, which is the same as in the second-first embodiment, a base portion 2-12, which is substantially the same as in the second-first embodiment, and an RFID tag 2-13.

[0141] The pedestal portion 2-12 includes an expansion portion 2-121 and a protrusion 2-122. The expansion portion 2-121 surrounds the base portion 2-112 of the shaft-shaped portion 2-11. The protrusion 2-122 protrudes from the base portion 2-112 in a plate-like manner. An RFID tag 2-13 is fixed to one side (referred to herein as the "surface") of the protrusion 2-122 using an adhesive. However, a recess (not shown) may also be formed from the surface of the protrusion 2-122 toward the back side, and the RFID tag 2-13 may be embedded in the recess. In summary, the main surface of the RFID tag 2-13 faces the cross-sectional direction, i.e., the RFID tag 2-13 shown in the figure is in an upright state.

[0142] The head 2-2 has a cap 2-21 covering the main part of the pedestal portion 2-12 of the RFID tag assembly unit 2-1, a pair of ribs 2-24, and an enhancement antenna 2-223. The head 2-2 is separately formed from the pedestal portion 2-12 and is designed to be detachable.

[0143] The cap 2-21 is designed to be integrally formed with a cylindrical portion and a frustum-shaped portion along the axial direction. A recessed portion 2-211 and a layered hole portion 2-212 are formed on the cylindrical portion of the cap 2-21 for inserting the protrusion 2-122 of the base portion 2-12. Each rib 2-24 protrudes from the cap 2-21 in the cross-sectional direction like a wing screw. Each rib 2-24 has a bottom edge orthogonal to the axial direction of the insertion portion 2-111, and an inclined portion that protrudes from the lower center in the axial direction relative to the insertion portion 2-111.

[0144] The pattern of the enhancement antenna 2-223 is formed in a meandering shape. When the length direction of the insertion part 2-111 is set as the width direction, the meandering enhancement antenna 2-223 is formed in such a way that the width is narrow at the base end side of the rib 2-24 and gradually widens at the front end side. The enhancement antenna 2-223 is built into the rib 2-24.

[0145] like Figure 28 As shown, in the first example of the second and third embodiments, the base ends of the meandering enhancement antennas 2-223 within each rib 2-24, i.e., the portions located within the center of the cap 2-21, are connected together. Figure 29 As shown, when the cap 2-21 is mounted on the base 2-12, the enhanced antenna 2-223 is capacitively coupled to the RFID tag 2-13.

[0146] like Figure 30 As shown, in the second example of the second embodiment of the second-third embodiment, the base ends of the meandering enhancement antenna 2-223 within each rib 2-24 are separated. At each base end of the enhancement antenna 2-223 located in the center of the cap 2-21, a wide pad electrode 2-223a is provided. Figure 30The pad electrode 2-223a shown is embedded in the rib 2-24. In the rib 2-24 where the pad electrode 2-223a is embedded, a recess 2-211 is formed eccentrically, that is, formed near the front or inner side of the pad electrode 2-223a (shown as the inner side in the drawing with a dashed line). On the other hand, on the pedestal portion 2-12 of the RFID tag assembly unit 2-1, a protrusion 2-122 protrudes eccentrically from the center and is embedded in the recess 2-211 of the rib 2-24. The RFID tag 2-13 is positioned upright in the cross-sectional direction.

[0147] Furthermore, although not illustrated, the pad electrode 2-223a may also be exposed within the recessed portion 2-211. In this case, with the rib 2-24 mounted as a protrusion 2-122 of the recessed base portion 2-12, the protrusion 2-122 is sandwiched between the pad electrode 2-223a and the RFID tag 2-13. In summary, as Figure 31 As shown, with the cap 2-21 mounted on the base 2-12, each pad electrode 2-223a of the enhanced antenna 2-223 is capacitively coupled to the RFID tag 2-13.

[0148] The enhanced antenna 2-223, which is a conductor with any meandering pattern, has both magnetic field coupling and capacitive coupling functions. Furthermore, the bolt with the RFID tag has the enhanced antenna 2-223, thereby amplifying even if the RFID tag 2-13 is a passive type that transmits and receives weak radio waves, improving its directivity in the cross-sectional direction and enabling reliable transmission and reception of radio waves with the reader.

[0149] Regarding the head 2-2 in embodiments 2-3, the reinforcement antenna 2-223 is patterned in various forms except in embodiments 1 and 2. For example, the reinforcement antenna 2-223 can be formed as a meandering shape with the same width from the base end side to the front end side, or the spacing can be provided at various intervals. Regarding the meandering reinforcement antenna 2-223 with the same width, the ribs 2-24 are formed with the same width over the entire length, that is, the upper and lower edges are parallel.

[0150] The bolt with the RFID tag is selected appropriately based on the installation conditions of the head 2-2 with various types of enhancement antennas 2-223.

[0151] [Implementation Methods 2-4] While referring to Figure 32 and Figure 33 The second to fourth embodiments of the RFID tag mounting component of the present invention will be described. Figure 32 This is a front cross-sectional view showing the head of the RFID tag mounting component and the RFID tag assembly unit of the second to fourth embodiments of the present invention. Figure 33 This is a front cross-sectional view showing the second to fourth embodiments of the RFID tag mounting component of the present invention.

[0152] like Figure 32 As shown, the bolt with RFID tag in the second-fourth embodiment includes an RFID tag assembly unit 1 and a head 2-2. The RFID tag assembly unit 2-1 includes a shaft-shaped portion 2-11, which is the same as in the second-first embodiment, a base portion 2-12, which is substantially the same as in the second-first embodiment, and an RFID tag 2-13.

[0153] The pedestal portion 12, as in embodiments 2-3, includes an expansion portion 2-121 and a protrusion 2-122. The expansion portion 2-121 surrounds the base portion 2-112 of the shaft-shaped portion 2-11. The protrusion 2-122 protrudes from the base portion 2-112 in a plate-like manner. An RFID tag 2-13 is fixed to one side (referred to herein as the "surface") of the protrusion 2-122 using an adhesive. However, a recess (not shown) may also be formed from the surface of the protrusion 2-122 toward the back side, and the RFID tag 2-13 may be embedded in the recess. In summary, the base edge (lower edge in the drawings) of the RFID tag 2-13 contacts the top surface of the base portion 2-112 of the shaft-shaped portion 2-11.

[0154] The head 2-2 has a cap 2-21 that covers the main part of the pedestal portion 2-12 of the RFID tag assembly unit 2-1 and an enhancement antenna 2-224. The head 2-2 is separately formed from the pedestal portion 2-12 and is designed to be detachable.

[0155] The cap 2-21 of the RFID tag mounting component in embodiments 2-4 differs from that in embodiment 2-1, having a cylindrical cap 2-21 and a flat rib 2-25 extending in one direction. The cap 2-21 has a recessed portion 2-211 into which the protrusion 2-122 of the base portion 12 is inserted, and a layer difference hole 2-212. The flat rib 2-25 protrudes in one direction in the cross-sectional direction from near the front end of the cap 2-21.

[0156] The enhancement antenna 2-224 has a conductive plate built into a flat rib 2-25. The enhancement antenna 2-224, except for its base end, is entirely built into the rib 2-25. That is, the base end of the enhancement antenna 2-224 protrudes into the recess 2-211 of the cap 2-21. Although not shown, the base end of the enhancement antenna 2-224 can also be shallowly embedded in the recess 2-211 of the cap 2-21. Figure 33As shown, when the cap 2-21 is mounted on the pedestal 2-12, the RFID tag 2-13 is capacitively coupled not only to the base plate 112 of the shaft 2-11 but also to the base end of the reinforcing antenna 2-224. The base end of the reinforcing antenna 2-224 has both magnetic field coupling and capacitive coupling functions.

[0157] Although not illustrated, the bolt with the RFID tag is stocked with various heads 2, each having an enhanced antenna 2-224 of different widths and / or lengths, or an enhanced antenna 2-224 extending in two or more directions. The various heads 2-2 are selected according to the installation requirements.

[0158] The bolt with the RFID tag has an enhanced antenna 2-224, which enhances the radio waves even if the RFID tag 2-13 is a passive type that transmits and receives weak radio waves, thereby improving the directivity in the cross-sectional direction and enabling reliable transmission and reception of radio waves with the reader.

[0159] [Other embodiments of the second embodiment] The embodiments of the RFID-tagged mounting component and the head of the RFID-tagged mounting component, which take the RFID-tagged bolt of the present invention as an example, and the RFID tag assembly unit are not limited to the above description, but also include modifications or improvements made within the scope of achieving the purpose of the present invention.

[0160] For example, in the second embodiment described above, the insertion part 2-111 is configured as a shaft with external threads. However, the insertion part 2-111 may also be a pin without external threads, and the pin is not limited to a cylindrical shape, but may also be prismatic.

[0161] Furthermore, in the second embodiment described above, the base plate portion 2-112 is formed in a disc shape. However, the base plate portion 2-112 may also be polygonal. Additionally, in the above embodiment, the outer peripheral surface of the base plate portion 2-112 has a chamfered portion 2-112a, and the head 2-2 has a locking portion that engages with the chamfered portion 2-112a. However, the outer peripheral surface of the base plate portion 2-112 may not have a chamfered portion 2-112a, but may instead be knurled, with the inner surface of the head 2-2 entering the knurling. Furthermore, when the base plate portion 2-112 and the head 2-2 are fixed integrally, the chamfered portion 2-112a may not be formed on the base plate portion 2-112, and the head 2-2 may not have a locking portion.

[0162] In addition, in the second embodiment described above, the RFID tag assembly unit is provided with a base plate portion 2-112. However, the RFID tag assembly unit 2-1 may not have a base plate portion 2-112, and one end of the shaft portion 2-11 may be provided as a pedestal portion 2-12, so that the head 2 can be attached and detached from the pedestal portion 2-12.

[0163] Furthermore, in the second embodiment described above, the insertion portion 2-111 and the base plate portion 2-112 are made of metal. However, one or both of the insertion portion 2-111 and the base plate portion 2-112 may also be made of resin.

[0164] Furthermore, in the second embodiment described above, it is assumed that the various headers 2-2 described in each embodiment can be changed in different embodiments. However, it is also possible to replace the headers 2-2 with those of different embodiments depending on the user's purpose. The different headers 2-2 in different embodiments can be addressed simply by increasing the variety of enhanced antennas 2-221 to 2-224, thereby reducing costs.

[0165] Furthermore, in the second embodiment described above, the head of the RFID tag mounting component, the RFID tag assembly unit, and the RFID tag mounting component were described as a group for each of the embodiments 2-1 to 2-4. However, the head of the RFID tag mounting component, the RFID tag assembly unit, and the RFID tag mounting component described in each embodiment may not be a group, but may be manufactured, transferred, or used separately.

[0169] The RFID tag mounting component includes enhancement antennas 1-4 and 2-221 that amplify the radio waves transmitted and received by the RFID tags 1-3 and 2-13. Therefore, even if the RFID tags 1-3 and 2-13 are passive tags that transmit and receive weak radio waves, they can reliably transmit and receive radio waves. Furthermore, the RFID tag mounting component, in which the RFID tags 1-3 and 2-13 and the enhancement antennas 1-4 and 2-221 are molded into the heads 1-2 and 2-2, can be manufactured at low cost in a way that prevents the RFID tags 1-3 and 2-13 and the enhancement antennas 1-4 and 2-221 from detaching from the base portions 1-12 and 2-112 of the shaft portion 1.
