Description

本発明は、リベットの締結方法及びアンテナの製造方法に関する。   The present invention relates to a rivet fastening method and an antenna manufacturing method.

従来、ソリッドリベットまたは中空リベット等のリベットの締結は、軸線方向に往復移動可能に設けられたステムと、前記ステムに対向して配置されるアンビルと、このアンビルの軸線に沿ってスライド自在に配置され常時ばねによりアンビルから突出する方向に付勢されているパイロットピンを用いる方法において、リベットがステムの下降にともなって被締結品の下穴に導入されるとともに、その下端面がアンビル上端面に押し付けられて締結される（例えば、特開２０００−１９７９４６号公報参照）。
特開２０００−１９７９４６号公報 Conventionally, a rivet such as a solid rivet or a hollow rivet is fastened with a stem that is reciprocally movable in the axial direction, an anvil that is disposed to face the stem, and a slide that is slidable along the axis of the anvil. In the method using a pilot pin that is constantly biased in a direction protruding from the anvil by a spring, the rivet is introduced into the prepared hole of the article to be fastened as the stem descends, and its lower end surface is at the upper end surface of the anvil. It is pressed and fastened (for example, refer to JP 2000-197946 A).
JP 2000-197946 A

リベットはネジ等に比べて締結時間が短く、被締結品への制約条件も少ないことから、様々な分野で用いられている。しかし、上記従来のリベット締結方法の場合、締結後リベットの下端面及び周辺に金属バリ及びカスが多数発生することから、金属バリ及びカスが不具合をもたらす被締結品（例えば回路基板のように回路短絡を起こすような被締結品）への適用は非常に困難である等の問題がある。本発明は、金属バリ及びカスの発生がなく、締結時間の短縮化を図ることによりコストダウンし、よって良好な特性のアンテナを製造することが可能となるリベットの締結方法及びこの方法を用いたアンテナの製造方法を提供することを目的とする。   Rivets are used in various fields because they have a shorter fastening time than screws or the like and have fewer constraints on the fastened products. However, in the case of the conventional rivet fastening method, a large number of metal burrs and debris are generated on and around the lower end surface of the rivet after fastening. There is a problem that it is very difficult to apply to a product to be fastened that causes a short circuit. The present invention uses a rivet fastening method and this method that are free of metal burrs and debris, reduce costs by shortening the fastening time, and thus can manufacture an antenna having good characteristics. An object of the present invention is to provide a method for manufacturing an antenna.

上記目的を達成するため、鋭意検討の結果、上記従来のリベット締結方法では、締結時リベットの下端面がアンビル上端面に押し付けられる際、リベットの下端面一部がアンビルとパイロットピンとの隙間に入り込んでしまうことにより、締結後リベットの下端面に鋭角の凸隆起が形成され、これが剥れたりして、金属バリやカスの発生することを究明した。この解決手段として、アンビルとパイロットピンの隙間をできるかぎり小さくすることを試みたが、凸隆起及びそれに起因した金属バリ及びカスの発生を完全に防止するには至らなかった。さらに検討を重ねた結果、締結時にリベットの下端面とアンビルの上端面とを離間させることにより、上記問題点を解決できることを見出し、本発明に至った。   As a result of intensive studies to achieve the above object, in the conventional rivet fastening method, when the lower end surface of the rivet is pressed against the upper end surface of the anvil at the time of fastening, a part of the lower end surface of the rivet enters the gap between the anvil and the pilot pin. As a result, it has been clarified that, after fastening, an acute convex ridge is formed on the lower end surface of the rivet, and this is peeled off to generate metal burrs and debris. As a means for solving this problem, an attempt was made to make the gap between the anvil and the pilot pin as small as possible, but it was not possible to completely prevent the convex bumps and the occurrence of metal burrs and debris. As a result of further studies, the present inventors have found that the above problems can be solved by separating the lower end surface of the rivet and the upper end surface of the anvil at the time of fastening, and have reached the present invention.

すなわち、本発明は、以下のとおりである。
（１）ステムと、ステムに対向して配置されるアンビルと、アンビルに沿ってスライドするパイロットピンとを用いて被締結品にリベットを締結する方法において、締結時にリベットの下端面とアンビルの上端面とが離間していることを特徴とするリベットの締結方法。
（２）さらにアンピルの内部にスペーサが配置され、締結時に該スペーサによりパイロットピンの下端面を受け止めることを特徴とする上記（１）に記載のリベットの締結方法。
（３）締結時にリベットの下端面とアンビルの上端面との離間距離Ａが、スペーサ厚みｃより小さいことを特徴とする上記（１）又は（２）に記載のリベットの締結方法。
（４）リベットがソリッドリベットまたは中空リベットである上記（１）〜（３）のいずれかに記載のリベットの締結方法。
（５）上記（１）〜（４）のいずれかのリベットの締結方法を用いて、アンテナ部品を締結する工程を有するアンテナの製造方法。 That is, the present invention is as follows.
(1) In a method for fastening a rivet to a product to be fastened using a stem, an anvil disposed opposite to the stem, and a pilot pin that slides along the anvil, a lower end surface of the rivet and an upper end surface of the anvil at the time of fastening And a rivet fastening method, wherein the rivets are separated from each other.
(2) The rivet fastening method according to the above (1), wherein a spacer is further arranged inside the ampil, and the lower end surface of the pilot pin is received by the spacer during fastening.
(3) The rivet fastening method according to the above (1) or (2), wherein a separation distance A between the lower end surface of the rivet and the upper end surface of the anvil is smaller than the spacer thickness c at the time of fastening.
(4) The rivet fastening method according to any one of (1) to (3), wherein the rivet is a solid rivet or a hollow rivet.
(5) A method for manufacturing an antenna including a step of fastening an antenna component using the rivet fastening method according to any one of (1) to (4) above.

以上の説明からも明らかなように本発明の締結方式によれば、締結時リベットの下端面とアンビルの上端面が離間した状態となるため、締結後リベット下端面に鋭角凸隆起が形成されず、金属バリ及びカスが発生しないことから、金属バリ及びカスが不具合をもたらす被締結品へ用いることが可能となる。また、ネジ等からリベットを新しく導入することで締結時間の短縮化を図ることができコストダウンにつながる。また、本発明のリベットの締結方法をアンテナの製造工程に採用することによって、良好な特性のアンテナを製造することが可能となる。よって、本発明は従来の問題点を解決し、リベットの適用範囲を拡大できることから、リベットによる締結方法として産業の発展に寄与することは大である。   As is clear from the above description, according to the fastening method of the present invention, since the lower end surface of the rivet and the upper end surface of the anvil are separated from each other at the time of fastening, no sharp convex ridge is formed on the lower end surface of the rivet after fastening. Since no metal burrs and debris are generated, the metal burrs and debris can be used for articles to be fastened that cause problems. In addition, by newly introducing rivets from screws or the like, the fastening time can be shortened, leading to cost reduction. Further, by adopting the rivet fastening method of the present invention in the antenna manufacturing process, it is possible to manufacture an antenna with good characteristics. Therefore, the present invention solves the conventional problems and can expand the range of application of rivets, and thus contributes to the development of industry as a fastening method using rivets.

本発明のリベット締結方法は、ステムと、ステムに対向して配置されるアンビルと、アンビルに沿ってスライドするパイロットピンとを用いて被締結品にリベットを締結する方法であって、締結時にリベットの下端面とアンビルの上端面とが離間していることを特徴とする。好ましくは、ステムは軸線方向に往復移動可能に設けられ、パイロットピンは、このステムに対向して配置されるアンビル内に、このアンビルの軸線に沿ってスライド自在に配置され、常時ばね等の付勢手段により押し上げられて、アンビルから突出するよう構成される。さらに、本発明のリベットの締結方法は、アンピルの内部にスペーサが配置され、締結時に該スペーサによりパイロットピンの下端面を受け止めることを特徴とすることが好ましい。   A rivet fastening method according to the present invention is a method of fastening a rivet to a product to be fastened using a stem, an anvil arranged to face the stem, and a pilot pin that slides along the anvil. The lower end surface is separated from the upper end surface of the anvil. Preferably, the stem is provided so as to be capable of reciprocating in the axial direction, and the pilot pin is slidably disposed along the axis of the anvil in the anvil disposed to face the stem, and is always attached with a spring or the like.

The distance A between the lower end surface of the rivet and the upper end surface of the anvil at the time of fastening is the difference between the distance a between the upper end surface of the rivet and the upper end surface of the anvil and the distance b between the upper end surface of the rivet and the upper end surface of the pilot pin a- It is preferable that it is less than b. In the present invention, the rivet used for fastening is not particularly limited, but a solid rivet or a hollow rivet is preferable.

（比較例１）
図５は従来の締結方法を用いた締結メカニズムを示す概略図である。まず、図５（ａ）に示すように、リベットホルダ１１にソリッドリベット６を保持し、被締結品１をソリッドリベット６とアンビル３との間のウレタン１０の上にセットする。被締結品には予めソリッドリベット６を挿入するための下穴９が形成されており、被締結品１をセットした時、この下穴９にはパイロットピン５が挿通する。次に図５（ｂ）に示すようにステム２を下降させることで、保持されたソリッドリベット６が下降しパイロットピン５に接触する。パイロットピン５と接触したソリッドリベット６はステム２とパイロットピン５との間で支持され、ステム２の下降にともなって被締結品１の下穴９に導入され、ソリッドリベット６の下端面がアンビル３の上端面に押し付けられ締結が完成する。このとき、締結前リベット６長さＬと、締結後リベット６’長さＬ’、締結時リベット６’上端面−アンビル３上端面間距離ｂの間には、Ｌ＞Ｌ’＝ｂという関係が成り立つ。 (Comparative Example 1)
FIG. 5 is a schematic view showing a fastening mechanism using a conventional fastening method. First, as shown in FIG. 5A, the solid rivet 6 is held in the rivet holder 11, and the article 1 to be fastened is set on the urethane 10 between the solid rivet 6 and the anvil 3. A pilot hole 5 for inserting the solid rivet 6 is formed in advance in the fastened product, and when the fastened product 1 is set, the pilot pin 5 is inserted into the pilot hole 9. Next, as shown in FIG. 5B, the stem 2 is lowered, so that the held solid rivet 6 is lowered and contacts the pilot pin 5. The solid rivet 6 in contact with the pilot pin 5 is supported between the stem 2 and the pilot pin 5 and is introduced into the pilot hole 9 of the fastened product 1 as the stem 2 descends, and the lower end surface of the solid rivet 6 is anvil. 3 is pressed against the upper end surface of 3 to complete the fastening. At this time, there is a relationship of L> L ′ = b between the rivet 6 length L before fastening, the rivet 6 ′ length L ′ after fastening, and the distance b between the rivet 6 ′ upper end surface and the upper end surface of the anvil 3 at the time of fastening. Holds.

締結時（締結後）のリベットの外観は、図４（ａ）に示すように、従来の締結方法では、締結後ソリッドリベットの下端面に鋭角凸隆起１２が発生する。また、下端面に凸隆起に起因する金属バリ及びカスが発生するが、これらバリ等の発生率は７５％（Ｎ＝１００）であった。   As shown in FIG. 4A, the external appearance of the rivet at the time of fastening (after fastening) is that an acute convex ridge 12 is generated on the lower end surface of the solid rivet after fastening, as shown in FIG. In addition, metal burrs and debris due to the raised protrusions were generated on the lower end surface, and the generation rate of these burrs and the like was 75% (N = 100).

続いて、本発明のリベットの締結方法を用いた締結メカニズムについて図３（ａ）及び（ｂ）を参照して説明する。本発明のリベットの締結方法は、図３（ａ）に示すように、まず、リベットホルダ１１にリベット６を保持し、被締結品１をリベット６とアンビル３との間のウレタン１０の上にセットする。被締結品には予めリベット６を挿入するための下穴９が形成されており、被締結品１をセットした時、この下穴９にはパイロットピン５が挿通する。   Next, a fastening mechanism using the rivet fastening method of the present invention will be described with reference to FIGS. 3 (a) and 3 (b). In the rivet fastening method of the present invention, as shown in FIG. 3 (a), first, the rivet 6 is held in the rivet holder 11, and the article 1 to be fastened is placed on the urethane 10 between the rivet 6 and the anvil 3. set. A pilot hole 5 for inserting the rivet 6 is formed in advance in the fastened product, and when the fastened product 1 is set, the pilot pin 5 is inserted into the pilot hole 9.

次にリベットホルダ１１に保持されたリベット６がステム２の下降にともなって被締結品１の下穴９に導入されることで締結され、図３（ｂ）に示すように、締結時においてパイロットピン５がスペーサ８厚みｃ分だけ上方でスライドが停止するため、締結時リベット６’の下端面とアンビル３の上端面とが離間した状態での締結が可能となる。このとき、締結前リベット６長さＬと、締結時リベット６’長さＬ’、締結時リベット６’上端面−アンビル３上端面間距離ｂとの間には、Ｌ＞ｂ＞Ｌ’という関係が成り立つ。また、締結時リベット６’の下端面とアンビル３の上端面との離間距離Ａは、スペーサ８厚みｃより小さくなり、最大離間距離はスペーサ８厚みｃに依存する。   Next, the rivet 6 held by the rivet holder 11 is fastened by being introduced into the pilot hole 9 of the article to be fastened 1 as the stem 2 is lowered, and as shown in FIG. Since the slide of the pin 5 stops above the spacer 8 by the thickness c, the fastening can be performed in a state where the lower end surface of the rivet 6 ′ and the upper end surface of the anvil 3 are separated from each other. At this time, L> b> L ′ between the rivet 6 length L before fastening, the rivet 6 ′ length L ′ at the time of fastening, and the distance b between the rivet 6 ′ at the time of fastening and the upper end surface of the anvil 3 A relationship is established. Further, the separation distance A between the lower end surface of the rivet 6 ′ during fastening and the upper end surface of the anvil 3 is smaller than the spacer 8 thickness c, and the maximum separation distance depends on the spacer 8 thickness c.

締結時（締結後）のリベットの外観は、図４（ｂ）に示すように、下端面に鋭角凸隆起１２は発生しておらず、金属バリ及びカスの発生も観られなかった（Ｎ＝１００）。   As shown in FIG. 4 (b), the appearance of the rivet at the time of fastening (after fastening) did not have an acute convex ridge 12 on the lower end surface, and no metal burrs and debris were observed (N = 100).
