Description

本発明は、ＩＣタグ、ＩＣラベル等のＲＦＩＤの通信検査を行うＲＦＩＤ検査システムに関する。   The present invention relates to an RFID inspection system that performs communication inspection of RFID such as an IC tag and an IC label.

近年、ＲＦＩＤ（Ｒａｄｉｏ Ｆｒｅｑｕｅｎｃｙ Ｉｄｅｎｔｉｆｉｃａｔｉｏｎ）と称される非接触型のＩＣタグ、ＩＣラベル等が急速に普及し、その使用も多岐にわたっている。このようなＲＦＩＤは、製造上の効率性から連続シート上に形成されて個々に通信検査を行うことから、検査対象のＲＦＩＤに対して隣接したＲＦＩＤの影響による誤読や搬送時の接触による搬送障害を回避する必要がある。   In recent years, non-contact type IC tags, IC labels, and the like called RFID (Radio Frequency Identification) have rapidly spread, and their use is also wide-ranging. Since such RFID is formed on a continuous sheet for manufacturing efficiency and individually performs a communication inspection, misreading due to the influence of adjacent RFID with respect to the RFID to be inspected or conveyance trouble due to contact during conveyance Need to avoid.

従来、連続シート上に形成されたＲＦＩＤの通信検査に際して、検査対象のＲＦＩＤにおける隣接したＲＦＩＤの影響を回避する手法として、シールド部材を設けることが知られている。   Conventionally, it is known to provide a shield member as a technique for avoiding the influence of adjacent RFIDs in the RFID to be inspected when performing communication inspection of RFIDs formed on a continuous sheet.

ここで、図５に、従来のＲＦＩＤ検査システムの構成説明図を示す。図５において、ＲＦＩＤ検査システム１０１は、シート１０２上に形成されたＲＦＩＤ１０３と通信を行うためのリーダライタアンテナ部１０４との間にシールド部材１０５を介在させ、当該シールド部材１０５に形成された開口部から当該リーダライタアンテナ部１０４を検査対象のＲＦＩＤ１０３Ａに対向させて通信により良否を判定するというものである（特許文献１参照）。   Here, FIG. 5 shows a configuration explanatory diagram of a conventional RFID inspection system. In FIG. 5, an RFID inspection system 101 has a shield member 105 interposed between a reader / writer antenna unit 104 for communicating with an RFID 103 formed on a sheet 102, and an opening formed in the shield member 105. Therefore, the reader / writer antenna unit 104 is made to face the RFID 103A to be inspected and the quality is determined by communication (see Patent Document 1).

特開２００３−０７６９４７号公報Japanese Patent Application Laid-Open No. 2003-076947

しかしながら、上記従来のＲＦＩＤ検査システムは、シールド部材１０５によって隣接するＲＦＩＤ１０３との通信が回避されるものの、シート１０２上に形成されたＲＦＩＤ１０３は、その供給部から検査位置を経て巻取部まで水平搬送されるのが一般的であることから、図５（Ｂ）に示すように、搬送時にシート１０２にバタツキが生じて検査対象のＲＦＩＤ１０３Ａに隣接するＲＦＩＤ１０３に対しても通信が行われて誤読する場合や、搬送時の接触による搬送障害を生じる場合がある。誤読に関しては通信周波数がＨＦ帯、ＵＨＦ帯で生じやすい。   However, although the conventional RFID inspection system avoids communication with the adjacent RFID 103 by the shield member 105, the RFID 103 formed on the sheet 102 is horizontally conveyed from the supply unit to the winding unit through the inspection position. As shown in FIG. 5B, when the sheet 102 is fluttered during conveyance and communication is performed with respect to the RFID 103 adjacent to the RFID 103A to be inspected as shown in FIG. In addition, there may be a transportation failure due to contact during transportation. Regarding misreading, the communication frequency is likely to occur in the HF band and the UHF band.

そこで、本発明は上記課題に鑑みなされたもので、検査対象のＲＦＩＤに対して隣接したＲＦＩＤの影響による誤読や搬送時の接触による搬送障害を回避するＲＦＩＤ検査システムを提供することを目的とする。   Accordingly, the present invention has been made in view of the above problems, and an object thereof is to provide an RFID inspection system that avoids misreading due to the influence of an RFID adjacent to an RFID to be inspected and conveyance failure due to contact during conveyance. .

上記課題を解決するために、請求項１の発明では、ＩＣモジュール、アンテナを備えるＲＦＩＤが連続シートの表面上に連設されて供給部より巻取部まで搬送されるもので、検査対象となるＲＦＩＤに対してリーダライタがアンテナ部を介して通信を行い、良否を検査するＲＦＩＤの検査システムであって、前記搬送経路中の前記リーダライタのアンテナ部に対応した位置に配置され、少なくとも検査対象のＲＦＩＤ及びこれに隣接するＲＦＩＤが設けられた前記連続シートの裏面を円弧状に巻き付けるシールド材で形成されると共に、当該リーダライタのアンテナ部に対応する部分に開口部が形成されて当該検査対象となるＲＦＩＤのみを位置させる検査用治具と、前記検査用治具に前記連続シートの裏面を密着させるための所定数の保持ローラと、を有する構成とする。   In order to solve the above-described problem, in the invention of claim 1, an RFID including an IC module and an antenna is continuously provided on the surface of the continuous sheet and conveyed from the supply unit to the winding unit, and is an inspection target. An RFID inspection system in which a reader / writer communicates with an RFID via an antenna unit and inspects the quality, and is disposed at a position corresponding to the antenna unit of the reader / writer in the transport path, and at least an inspection target And a shield material that wraps the back surface of the continuous sheet provided with the RFID adjacent thereto in an arc shape, and an opening is formed in a portion corresponding to the antenna portion of the reader / writer, and the inspection object An inspection jig for positioning only the RFID to be used, and a predetermined number of holdings for bringing the back surface of the continuous sheet into close contact with the inspection jig A configuration that has an over La, a.

請求項２の発明では、前記検査用治具の幅方向の一端若しくは両端に、前記連続シートを幅方向にガイドするガイド部を備える構成である。   In the invention of claim 2, a guide portion for guiding the continuous sheet in the width direction is provided at one or both ends in the width direction of the inspection jig.

本発明によれば、ＲＦＩＤが連設された連続シートの搬送経路中のリーダライタによる検査を行う位置に配置され、少なくとも検査対象のＲＦＩＤ及びこれに隣接するＲＦＩＤが設けられた連続シートの裏面を円弧状に巻き付けるシールド材で形成されると共に、当該リーダライタのアンテナ部に対応する部分に開口部が形成されて検査対象となるＲＦＩＤのみを位置させる検査用治具を設け、検査用治具に連続シートの裏面を密着させるための所定数の保持ローラを設ける構成とすることにより、少なくとも検査用治具上では連続シートの搬送時のバタツキを回避させて当該検査用治具の開口部上に位置させた検査対象のＲＦＩＤのアンテナをリーダライタのアンテナ部に正対させて隣接されるＲＦＩＤのアンテナを正対させないようにすることができると共に、隣接されるＲＦＩＤの裏面がシールド材に密着されていることからリーダライタのアンテナ部との通信障害を生じさせることができることから、検査対象のＲＦＩＤに対して隣接したＲＦＩＤの影響による誤読を回避させることができるものである。   According to the present invention, at least the back surface of the continuous sheet provided with the RFID to be inspected and the RFID adjacent thereto is disposed at a position where inspection is performed by the reader / writer in the conveyance path of the continuous sheet in which the RFID is continuously provided. An inspection jig that is formed of a shield material wound in an arc shape and has an opening formed in a portion corresponding to the antenna portion of the reader / writer to position only the RFID to be inspected is provided in the inspection jig. By providing a predetermined number of holding rollers for bringing the back surface of the continuous sheet into close contact with each other, at least on the inspection jig, it avoids fluttering during the conveyance of the continuous sheet, and on the opening of the inspection jig. Position the RFID antenna to be inspected directly to the reader / writer's antenna so that the adjacent RFID antenna does not face. In addition, because the back surface of the adjacent RFID is in close contact with the shield material, a communication failure with the antenna unit of the reader / writer can be caused. Therefore, the influence of the adjacent RFID on the RFID to be inspected Can be avoided.

以下、本発明の最良の実施形態を図により説明する。
図１に、本発明におけるＲＦＩＤ検査システムの構成図を示す。図１（Ａ）はＲＦＩＤ検査システムの構成図、図１（Ｂ）、（Ｃ）は検査用治具の構成図である。図１（Ａ）において、ＲＦＩＤ検査システム１１は、表面上にＩＣモジュール、アンテナを備えるＲＦＩＤが連設された連続シート（２１、図２で説明する）を連続シート供給部１２より連続シート巻取部１３まで、例えば連続シート巻取部１３の回転駆動（連続シート供給部１２を補助的に回転駆動してもよい）により搬送するもので、搬送経路中にＲＦＩＤ検出部１４、リーダライタアンテナ部１５、スタンパ１６が配置される。 Hereinafter, the best embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a configuration diagram of an RFID inspection system according to the present invention. FIG. 1A is a configuration diagram of an RFID inspection system, and FIGS. 1B and 1C are configuration diagrams of an inspection jig. In FIG. 1 (A), the RFID inspection system 11 takes up a continuous sheet (21, described with reference to FIG. 2) in which an RFID module having an IC module and an antenna on the surface is continuously provided from a continuous sheet supply unit 12. For example, the continuous sheet take-up unit 13 is conveyed by rotational driving (the continuous sheet supply unit 12 may be rotationally driven auxiliary), and the RFID detection unit 14 and the reader / writer antenna unit are included in the conveyance path. 15. A stamper 16 is arranged.

リーダライタアンテナ部１５の配置位置が搬送経路中の検査位置となり、当該検査位置に検査用治具１７が配置され、当該検査用治具１７の両側に保持ローラ１８，１９が配置される。すなわち、連続シート供給部１２より供給される連続シートは、ＲＦＩＤ検出部１４の近傍を通って、保持ローラ１８から検査用治具１７に巻き付けられて保持ローラ１９で向きを変え、スタンパ１６を介して連続シート巻取部１３で巻き取られる搬送経路となる。   The arrangement position of the reader / writer antenna unit 15 becomes the inspection position in the transport path, the inspection jig 17 is arranged at the inspection position, and the holding rollers 18 and 19 are arranged on both sides of the inspection jig 17. In other words, the continuous sheet supplied from the continuous sheet supply unit 12 passes through the vicinity of the RFID detection unit 14, is wound around the inspection jig 17 from the holding roller 18, changes its direction by the holding roller 19, and passes through the stamper 16. Thus, the conveyance path is taken up by the continuous sheet take-up unit 13.

上記ＲＦＩＤ検出部１４は、搬送されるＲＦＩＤの検査対象のＲＦＩＤを検出するセンサである。上記リーダライタアンテナ部１５は、例えば図示しない検査判別手段におけるＲＦＩＤと通信を行うためのもので、従前のものが使用可能であることから詳細な説明は省略する。上記スタンパ１６は、通信検査を行った結果として不良品と判別されたＲＦＩＤに対してＮＧ（例えば「×」）マークをスタンプする。   The RFID detection unit 14 is a sensor that detects an RFID to be inspected for the RFID being conveyed. The reader / writer antenna unit 15 is for communicating with an RFID in, for example, an inspection discriminating unit (not shown), and since a conventional one can be used, a detailed description is omitted. The stamper 16 stamps an NG (for example, “x”) mark on the RFID that is determined to be defective as a result of the communication inspection.

上記検査用治具１７は、図１（Ｂ）、（Ｃ）に示すように、複数のＲＦＩＤが連設された部分の連続シートの裏面を円弧状に巻き付けるシールド材で形成された中空円筒状のもので、リーダライタアンテナ部１５に対応する部分に開口部２０が形成されて検査対象となるＲＦＩＤのみを位置させる。そのシールド材としては、１３．５６ＭＨｚ帯等の電磁波による電磁誘導方式の場合には、金属粒子を樹脂に含有させた電磁波シールド等は電磁波の誘引がある可能性があるために金属等が好適に用いられる。ＵＨＦ帯等のマイクロ波方式の電波方式の場合には、金属板または金属粒子を樹脂に含有させた電磁波シールド等の双方を使用することができるものである。   As shown in FIGS. 1B and 1C, the inspection jig 17 has a hollow cylindrical shape formed of a shield material that wraps the back surface of a continuous sheet in a portion where a plurality of RFIDs are continuously provided in an arc shape. The opening 20 is formed in a portion corresponding to the reader / writer antenna unit 15 and only the RFID to be inspected is positioned. As the shielding material, in the case of an electromagnetic induction method using an electromagnetic wave of 13.56 MHz band or the like, an electromagnetic wave shielding or the like in which metal particles are contained in a resin may induce electromagnetic waves, and therefore, a metal or the like is preferable. Used. In the case of a microwave radio system such as a UHF band, both a metal plate or an electromagnetic wave shield containing metal particles in a resin can be used.

なお、本実施形態では、検査用治具１７を円筒状とした場合を示したが、少なくとも検査対象のＲＦＩＤ２２Ａ及びこれに隣接するＲＦＩＤ２２が形成された連続シート２１の裏面を巻き付ける部分が円弧状であって、当該部分が金属等のシールド材で形成されていれば足りるものである。   In the present embodiment, the inspection jig 17 has a cylindrical shape, but at least the portion of the continuous sheet 21 on which the RFID 22A to be inspected and the RFID 22 adjacent thereto are wound is wound in an arc shape. In addition, it is sufficient if the portion is formed of a shielding material such as metal.

上記保持ローラ１８．１９は、上記検査用治具１７の両側に配置されて、当該検査用治具１７に連続シートの裏面を密着させるためのものである。換言すれば、例えば連続シート巻取部１３の巻取駆動による搬送力で当該保持ローラ１８，１９によって連続シートの裏面が検査用治具１７に密着状態とされるものである。   The holding rollers 18.19 are arranged on both sides of the inspection jig 17 so that the back surface of the continuous sheet is in close contact with the inspection jig 17. In other words, for example, the back surface of the continuous sheet is brought into close contact with the inspection jig 17 by the holding rollers 18 and 19 by the conveying force by the winding drive of the continuous sheet winding unit 13.

ここで、図２に、図１のＲＦＩＤ検査システムで検査される対象の一例の説明図を示す。図２（Ａ）は連続シートの説明図、図２（Ｂ）は連続シートが検査用治具に巻き付けられた状態を示した説明図である。図２（Ａ）において、例えばポリエチレンテレフタレート（ＰＥＴ）の連続シート２１上にＲＦＩＤ２２が一列に連続して所定間隔で剥離自在に取着されたものである。   Here, FIG. 2 shows an explanatory diagram of an example of an object to be inspected by the RFID inspection system of FIG. FIG. 2A is an explanatory view of a continuous sheet, and FIG. 2B is an explanatory view showing a state in which the continuous sheet is wound around an inspection jig. In FIG. 2A, for example, RFIDs 22 are continuously attached in a row on a continuous sheet 21 of polyethylene terephthalate (PET) so as to be peeled at predetermined intervals.

当該ＲＦＩＤ２２は、例えばＰＥＴ上に銅箔をエポキシ系接着剤で接着し、エッチングにより平面状とした各アンテナを形成し、当該各アンテナ間にＩＣモジュール（ＩＣチップ若しくはＩＣチップに所定の回路を形成したもの）をリフローはんだ付け若しくは導電性接着剤により実装させたもので、当該アンテナとリーダライタアンテナ部１５との間で所定周波数（ＲＦＩＤのアンテナの形状等で定まるもので、ここではＵＨＦ帯としている）による通信が行われるものである。   For example, the RFID 22 is formed by bonding copper foil onto a PET with an epoxy-based adhesive and forming each planar antenna by etching, and forming an IC module (IC chip or a predetermined circuit on the IC chip) between the antennas. Is mounted by reflow soldering or conductive adhesive, and is determined by the predetermined frequency (RFID antenna shape, etc.) between the antenna and the reader / writer antenna unit 15. Here, as the UHF band Communication) is performed.

ところで、ＲＦＩＤ２２は、アンテナ部の形状、長さ等により所定の共振周波数を有しており、リーダライタアンテナ部１５からの対応周波数の電波に反応して共振することにより受信を行う。したがって、当該ＲＦＩＤ２２のアンテナとリーダライタアンテナ部１５とが正対しない場合には通信機能が劣化し、また、連続シートの当該ＲＦＩＤに対応する裏面にシールド材が存在すると当該シールド材が金属反射板としての機能を果たして通信機能を極端に劣化させるものである。   By the way, the RFID 22 has a predetermined resonance frequency depending on the shape, length, and the like of the antenna unit, and performs reception by resonating in response to a radio wave of a corresponding frequency from the reader / writer antenna unit 15. Therefore, when the antenna of the RFID 22 and the reader / writer antenna unit 15 do not face each other, the communication function is deteriorated, and when a shield material is present on the back surface of the continuous sheet corresponding to the RFID, the shield material becomes a metal reflector. The communication function is extremely deteriorated by fulfilling the function as described above.

上記ＲＦＩＤ２２が連設された連続シート２１は、図２（Ｂ）に示すように、保持ローラ１８を介して検査用治具１７に巻き付けられ、保持ローラ１９で水平搬送経路に方向転換される。そして、検査用治具１７に形成された開口部２０にＲＦＩＤ２２のみが位置されたときに通信検査が行われるものである。   As shown in FIG. 2B, the continuous sheet 21 provided with the RFID 22 is wound around the inspection jig 17 via the holding roller 18, and the direction is changed to the horizontal conveyance path by the holding roller 19. A communication inspection is performed when only the RFID 22 is positioned in the opening 20 formed in the inspection jig 17.

そこで、図３に、図１における検査用治具による通信検査の説明図を示す。図３において、検査用治具１７に巻き付けられた連続シート２１は、開口部２０で位置されたＲＦＩＤ２２Ａが検査対象となる。通信検査に際しては、検査対象のＲＦＩＤ２２Ａが、リーダライタアンテナ部１５からの対応周波数（ＵＨＦ帯）の電波に反応して共振することにより受信が行われ、リーダライタからの電波に含まれるコマンドに応じて当該ＲＦＩＤ２２Ａよりデータが送信されて良否が判別される。   FIG. 3 is an explanatory diagram of communication inspection using the inspection jig in FIG. In FIG. 3, the continuous sheet 21 wound around the inspection jig 17 is subject to inspection with the RFID 22 </ b> A positioned at the opening 20. In the communication inspection, the RFID 22A to be inspected is received by resonating in response to the radio wave of the corresponding frequency (UHF band) from the reader / writer antenna unit 15, and according to the command included in the radio wave from the reader / writer. Then, data is transmitted from the RFID 22A, and the quality is determined.

このとき、検査対象のＲＦＩＤ２２Ａに隣接するＲＦＩＤ２２においてもリーダライタアンテナ部１５から対応周波数（ＵＨＦ帯）の電波が発信されることとなるが、当該ＲＦＩＤ２２のアンテナとリーダライタアンテナ部１５とが正対しないことから通信機能が劣化され、また、連続シート２１の当該ＲＦＩＤ２２に対応する裏面に検査用治具１７のシールド材が存在することから金属反射板としての機能を果たして通信機能を極端に劣化されることによって、当該隣接したＲＦＩＤ２２から応答がなく、リーダライタアンテナ部１５では受信されないこととなるものである。   At this time, radio waves of the corresponding frequency (UHF band) are also transmitted from the reader / writer antenna unit 15 in the RFID 22 adjacent to the RFID 22A to be inspected, but the antenna of the RFID 22 and the reader / writer antenna unit 15 face each other. The communication function is deteriorated because of the absence of this, and the shield material of the inspection jig 17 is present on the back surface of the continuous sheet 21 corresponding to the RFID 22 so that the communication function is extremely deteriorated by serving as a metal reflector. Accordingly, there is no response from the adjacent RFID 22 and the reader / writer antenna unit 15 does not receive the response.

このように、少なくとも検査用治具１７上では連続シート２１の裏面が密着されることから搬送時のバタツキが回避されて当該検査用治具１７の開口部２０上に位置させた検査対象のＲＦＩＤ２２Ａのアンテナをリーダライタアンテナ部１５に正対させて隣接されるＲＦＩＤ２２を正対させないようにすることができるものである。また、隣接されるＲＦＩＤ２２の裏面が検査用治具１７のシールド材部分に密着されていることからリーダライタアンテナ部１５との通信状態を極端に劣化させて通信障害を生じさせることができる。これによって、検査対象のＲＦＩＤ２２Ａに対して隣接したＲＦＩＤ２２の影響による誤読を回避させることができるものである。   As described above, since the back surface of the continuous sheet 21 is in close contact with at least the inspection jig 17, flapping during conveyance is avoided, and the RFID 22 </ b> A to be inspected is positioned on the opening 20 of the inspection jig 17. These antennas can be directly opposed to the reader / writer antenna unit 15 so that the adjacent RFID 22 is not directly opposed. In addition, since the back surface of the adjacent RFID 22 is in close contact with the shield material portion of the inspection jig 17, the communication state with the reader / writer antenna unit 15 can be extremely deteriorated to cause a communication failure. As a result, erroneous reading due to the influence of the RFID 22 adjacent to the RFID 22A to be inspected can be avoided.

次に、図４に、図１における検査用治具の他の構成図を示す。図４において、検査用治具１７Ａを、幅方向の両端（一方端でもよい）にガイド部３１Ａ，３１Ｂを備える構成としたものであり、当該ガイド部３１Ａ，３１Ｂにより搬送される連続シート２１を幅方向でガイドさせるものである。   Next, FIG. 4 shows another configuration diagram of the inspection jig in FIG. In FIG. 4, the inspection jig 17 </ b> A is configured to include guide portions 31 </ b> A and 31 </ b> B at both ends (or one end) in the width direction, and the continuous sheet 21 conveyed by the guide portions 31 </ b> A and 31 </ b> B. It is to guide in the width direction.

これによって、連続シート２１が検査用治具１７Ａに巻き付けられて搬送される際に、ガイド部３１Ａ，３１Ｂが当該連続シート２１をガイドすることにより当該検査用治具１７Ａ上でブレを生じることなく搬送させることができ、ひいては検査対象のＲＦＩＤ２２Ａを確実に開口部２０の範囲内に位置させることができるものである。   As a result, when the continuous sheet 21 is wound around the inspection jig 17A and conveyed, the guide portions 31A and 31B guide the continuous sheet 21 without causing blur on the inspection jig 17A. Thus, the RFID 22A to be inspected can be surely positioned within the range of the opening 20.

本発明のＲＦＩＤ検査システムは、ＲＦＩＤの製造工程上若しくは出荷後のユーザ受入段階で行われる通信検査に利用可能である。   The RFID inspection system of the present invention can be used for communication inspection performed in the RFID manufacturing process or at the user acceptance stage after shipment.
