Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem that a conventional holder for a plate such as a printed-circuit board is required to eliminate the necessity of forming holes in the plate, and to hold the plate in the state of applying a plane-retaining force (tension). <P>SOLUTION: A holder has a structure of vertically hanging a plate to be treated, being made of an upper and lower frame plates which are longer than one side of the above plate to be treated and have freely rotatable clamps each installed in the vicinity of both ends, making the freely rotatable clamps arranged in the upper and lower frame plates each set slant to the inside, and sandwich each of the vicinity of both corners of the upper part and the lower part of the plate to be treated, and making the holder hold the plate to be treated in the state of giving the tension to the plate in the outward direction by making each clamp rotate so as to open to the outside by the weight of the plate to be treated and the lower frame plate. Thereby, the holder can easily hold the plate to be treated in the state of giving the plane-retaining force (the tension) to the plate to be treated, without needing to form a hole or the like in the plate. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【０００１】
【発明の属する技術分野】
本発明は、例えば、プリント配線基板等の被処理板材に張力を付与した状態で垂直に懸吊する被処理板材の保持治具に関するものである。
【０００２】
【従来の技術】
従来、被処理板材、例えば、プリント配線基板等に化学めっき、電解めっき、電解脱脂または電解エッチング等の処理をする場合には、該プリント配線基板を枠で挟み込む形態の治具で保持または該プリント配線基板の上部をクリップ等で挟持して前記処理を行っている。
【０００３】
前記プリント配線基板を枠で挟み込む形態の治具としては、例えば、保持部材と幅決め調節部材とからなる治具本体と、該保持部材を包被する被覆部と該治具部材の対向する側壁間に挟持空間を形成した断面略コ字状の係止部とからなる係止部材と、該係止部材を包被し枢軸のまわりに回動自在に設けられた挟持部材とからなるプリント基板メッキ用治具がある（特許文献１参照）。
【０００４】
この特許文献１の公知技術は、簡単な構造で、プリント基板の着脱を容易にしてプリント基板を固定するプリント基板メッキ用治具である。
【０００５】
このプリント配線基板は、該プリント配線基板を配設する電子機器等が小型・軽量化を要望されていることから、該プリント配線基板も薄型・軽量化、例えば、ポリイミド材または０．０４ｔのエポキシ材等を使用する場合もある。
【０００６】
【特許文献１】
特開２０００−２９０７９７号公報（請求項１、図１）
【０００７】
【発明が解決しようとする課題】
しかしながら、前記特許文献１の公知技術においては、単にプリント基板を保持するだけであり、該プリント基板に平面保持力（張力）が付与されていないため、前記化学めっき、電解めっき、電解脱脂または電解エッチング等の処理をする場合に、該プリント基板に反り・曲がりが生じ、特に、薄型・軽量化された該プリント基板の該処理をする場合には、その反り・曲がりが大きくなってしまうという問題点がある。
【０００８】
また、ゴム等のスプリングを有するプリント配線基板等の被処理板材を保持する治具も使用されているが、該プリント配線基板に専用の孔等を形成させる必要があり、張力を付与するための事前の作業工程が多いという問題点がある。
【０００９】
従って、従来のプリント配線基板等の被処理板材の保持治具においては、該被処理板材に孔等を形成させる必要がなく、該被処理板材に平面保持力（張力）を付与した状態で簡単に保持できるようにするということに解決しなければならない課題を有する。
【００１０】
【課題を解決するための手段】
上記した従来例の課題を解決する具体的手段として本発明に係る第１の発明として、被処理板材を垂直に懸吊する治具であって、前記被処理板材の一辺よりも長尺で且つ両端部近傍に回転自在なクランプをそれぞれ配設した上下の枠板からなり、該上下の枠板に配設された回転自在なクランプをそれぞれ内側に傾斜させて前記被処理板材の上側と下側の両角部近傍をそれぞれ挟持させ、前記被処理板材と下枠板との重量により各クランプが外側に開くように回転して被処理板材に外側方向の張力を付与する状態で保持する構成にしたことを特徴とする被処理板材保持治具を提供するものである。
【００１１】
また、第２の発明として、被処理板材を垂直に懸吊する治具であって、前記被処理板材の一辺よりも長尺な上下の枠板と、該上下の枠板の各両端部に回転自在な継ぎ手板を介して連結され且つ上下両端部近傍の内側にクランプをそれぞれ配設した左右の枠板とからなり、該左右の枠板をそれぞれ内側に寄せた状態にして各クランプで前記被処理板材の左右の両角部近傍をそれぞれ挟持させ、前記被処理板材と下枠板との重量により前記左右の枠板がそれぞれ外側に移動または開いて被処理板材に外側方向の張力を付与する状態で保持する構成にしたことを特徴とする被処理板材保持治具を提供するものである。
【００１２】
更に、第３の発明として、被処理板材を垂直に懸吊する治具であって、前記被処理板材の一辺よりも長尺な上下の枠板と、該上下の枠板の各両端部に継ぎ手板を介してスライド自在に連結され且つ上下両端部近傍の内側にクランプをそれぞれ配設した左右の枠板とからなり、該左右の枠板をそれぞれ上方にスライドさせ内側に寄せた状態にして各クランプで前記被処理板材の左右の両角部近傍をそれぞれ挟持させ、前記被処理板材と下枠板との重量により前記左右の枠板がそれぞれ下方にスライドし外側に移動または開いて被処理板材に外側方向の張力を付与する状態で保持する構成にしたことを特徴とする被処理板材保持治具を提供するものである。
【００１３】
この第１乃至第３の発明において、前記上枠板には、懸吊保持手段が設けられていること；前記クランプには、被処理板材の挟持位置に回転板を配設してあること；を付加的な要件として含むものである。
【００１４】
本発明に係る被処理板材保持治具は、被処理板材の一辺よりも長尺で且つ両端部近傍に回転自在なクランプをそれぞれ配設した上下の枠板からなり、該上下の枠板に配設された回転自在なクランプをそれぞれ内側に傾斜させて前記被処理板材の上側と下側の両角部近傍をそれぞれ挟持する、または、被処理板材の一辺よりも長尺な上下の枠板と、該上下の枠板の各両端部に回転自在な継ぎ手板を介して連結され且つ上下両端部近傍の内側にクランプをそれぞれ配設した左右の枠板とからなり、該左右の枠板をそれぞれ内側に寄せた状態にして各クランプで前記被処理板材の左右の両角部近傍をそれぞれ挟持する、または、被処理板材の一辺よりも長尺な上下の枠板と、該上下の枠板の各両端部に継ぎ手板を介してスライド自在に連結され且つ上下両端部近傍の内側にクランプをそれぞれ配設した左右の枠板とからなり、該左右の枠板をそれぞれ上方にスライドさせ内側に寄せた状態にして各クランプで前記被処理板材の左右の両角部近傍をそれぞれ挟持することにより、該被処理板材に孔等を形成させる必要がなく、該被処理板材に張力を付与した状態で簡単に該被処理板材を保持することができる。
【００１５】
【発明の実施の形態】
次に、本発明を具体的な実施の形態に基づいて詳しく説明する。
本発明の第１の実施の形態に係る被処理板材を垂直に懸吊し保持する治具を略示的に示した正面図を図１に示す。被処理板材保持治具１は、被処理板材２の一辺（横方向の長さ）よりも長尺な上枠板３と下枠板４とからなり、上枠板３の略中央部には、化学めっき、電解めっき、電解脱脂または電解エッチング等の処理装置に保持される保持部５が形成されている。この被処理板材２としては、例えば、ポリイミド材または０．０４ｔのエポキシ材等を基材とするプリント配線基板等の被処理板材を用いることができる。
【００１６】
上枠板３の側面の両端部の近傍には、それぞれ回転自在なクランプ６ａ、６ｂが配設されており、該回転自在なクランプ６ａ、６ｂをそれぞれ内側に傾斜させて、被処理板材２の上側の両角部の近傍（上側の両端部）を挟持している。
【００１７】
また、下枠板４の側面の両端部の近傍にも、それぞれ回転自在なクランプ７ａ、７ｂが配設されており、該回転自在なクランプ７ａ、７ｂをそれぞれ内側に傾斜させて、被処理板材２の下側の両角部近傍（下側の両端部）を挟持している。
【００１８】
図２（ａ）に、回転自在なクランプ６ａの拡大した平面図を示し、（ｂ）に、（ａ）のＡ−Ａ線に沿う断面図を示す。なお、回転自在なクランプ６ｂ、７ａ、７ｂについては、回転自在なクランプ６ａと同一の構成であるため、代表して回転自在なクランプ６ａを説明し、回転自在なクランプ６ｂ、７ａ、７ｂについては、説明を省略する。
【００１９】
回転自在なクランプ６ａは、２枚の挟片８、９からなり、該２枚の挟片８、９に形成された垂下部８ａ、９ａを連結ピン１０で動作可能な状態に連結されている。
【００２０】
２枚の挟片８、９に形成された垂下部８ａ、９ａには、図示はしていないが弾性体が配設されており、該弾性体により挟片８、９の挟持部８ｂ、９ｂには、常に被処理板材２を挟持する挟持力が付与されている。
【００２１】
この挟持部８ｂ、９ｂには、回転止めネジ１１ａ、１１ｂにより回転可能な状態で係止された一対の回転板１２ａ、１２ｂを配設させても良く、このように、回転板１２ａ、１２ｂを配設させることにより、回転自在なクランプ６ａにより被処理板材２を挟持しつつ、該回転自在なクランプ６ａと該被処理板材２との角度が変化した場合であっても、該角度が自然にバランスの良い角度にできるのである。
【００２２】
また、挟片８は、回転止めネジ１１ｃにより回転可能な状態で上枠板３の側面の端部に係止されている。
【００２３】
上枠板３と下枠板４とに配設された回転自在なクランプ６ａ、６ｂ、７ａ、７ｂに、上側と下側の両角部近傍、即ち、四隅を挟持された被処理板材２には、該被処理板材２と下枠板４との重量により矢印ｗ１、ｗ２の重力がかかり、回転自在なクランプ６ａ、６ｂ、７ａ、７ｂは該被処理板材２を挟持しつつ回転止めネジ１１ｃを中心として外側に開くように回転する。
【００２４】
その際、被処理板材２の一辺よりも上枠板３と下枠板４とが長尺であり、その上枠板３と下枠板４との両端部近傍に前記回転自在なクランプ６ａ、６ｂ、７ａ、７ｂが配設され、該回転自在なクランプ６ａ、６ｂ、７ａ、７ｂをそれぞれ内側に傾斜させた状態で前記被処理板材２を挟持させているため、前記矢印ｗ１、ｗ２の重力は、矢印ａと矢印ｂとに分割され、該矢印ａと矢印ｂとの合力として、矢印ｐ１、ｐ２、ｐ３、ｐ４の方向、即ち被処理板材２に外側方向に平面保持力（張力）が生じることになる。
【００２５】
このように、被処理板材２よりも長尺の上枠板３と下枠板４との側面の両端部に回転自在なクランプ６ａ、６ｂ、７ａ、７ｂを配設して該被処理板材２を挟持することにより、該被処理板材２に外側方向（矢印ｐ１、ｐ２、ｐ３、ｐ４の方向）の平面保持力（張力）を付与した状態で該被処理板材２を簡単に保持することができるため、例えば、薄型・軽量化されたプリント配線基板等の被処理板材に化学めっき、電解めっき、電解脱脂または電解エッチング等の処理をする場合であっても、該被処理板材に反り・曲がり等が生じないのである。
【００２６】
本発明の第２の実施の形態に係る被処理板材保持治具２１を略示的に示した正面図を図３（ａ）に示し、その一部を拡大した正面図を（ｂ）に示す。なお、この第２の実施の形態においては、前記第１の実施の形態の回転自在なクランプ６ａ、６ｂ、７ａ、７ｂを回転自在な継ぎ手板に換え、該回転自在な継ぎ手板を左右の枠板に連結し、該左右の枠板に配設されたクランプで被処理板材を挟持するものであり、その他の構成については、前記第１の実施の形態と同一であり、説明が重複するため、該第１の実施の形態と同一のものについては同一の符号を付し、その説明については省略する。
【００２７】
この第２の実施の形態においては、図３（ａ）に示したように、被処理板材保持治具２１の上枠板３と下枠板４との側面の両端部に回転自在な継ぎ手板２２を配設し、該回転自在な継ぎ手板２２に左枠板２３と右枠板２４とを連結させる。
【００２８】
この際、上枠板３と下枠板４との連結部２５ａ、２５ｂ、２６ａ、２６ｂよりも左枠板２３と右枠板２４との連結部２７ａ、２７ｂ、２８ａ、２８ｂの方が内側に位置するようにそれぞれの枠板を連結、即ち、上枠板３の側面の左右の端部に左枠板２３と右枠板２４との上部側の端部を連結し、該左枠板２３と右枠板２４との下部側の端部に下枠板４の側面の左右の端部を連結させるのである。
【００２９】
左枠板２３と右枠板２４とには、それぞれ少なくとも２つのクランプ２９を配設し、該クランプ２９により被処理板材２の四隅を挟持する。
【００３０】
左枠板２３と右枠板２４とは、回転自在な継ぎ手板２２により上枠板３と下枠板４とに連結される際、該上枠板３と下枠板４との連結部２５ａ、２５ｂ、２６ａ、２６ｂよりも、左枠板２３と右枠板２４との連結部２７ａ、２７ｂ、２８ａ、２８ｂの方が内側に位置するように連結されるため、図３（ｂ）に点線で示したように、被処理板材２と下枠板４との重さにより前記回転自在な継ぎ手板２２が連結部２５ａを中心として自然に外側方向に回転することになり、該左枠板２３（右枠板２４）は、下側乃至外側方向、即ち矢印ａの方向（右枠板２４は矢印ａと反対の方向）に移動することになる。
【００３１】
このように、被処理板材２の一辺よりも長尺な上枠板３と下枠板４との各両端部に回転自在な継ぎ手板２２を介して、該上枠板３と下枠板４との近傍の内側にクランプ２９をそれぞれ配設した左枠板２３と右枠板２４とを連結させ、該左枠板２３と右枠板２４とをそれぞれ内側に寄せた状態にして各クランプ２９で前記被処理板材２の左右の両角部近傍、即ち、該被処理板材２の四隅をそれぞれ挟持させ、該被処理板材２と下枠板４との重量により前記左枠板２３と右枠板２４とが、それぞれ外側方向に移動または開くことにより、該左枠板２３と右枠板２４とに配設されたクランプ２９に四隅を挟持された被処理板材２は、外側方向（左右方向）に張力が付与された状態で保持されるため、該被処理板材２に反り・曲がり等が生じないのであり、更に、該被処理板材２に横方向への捻れも生じないのである。
【００３２】
本発明の第３の実施の形態に係る被処理板材保持治具の一部を拡大し略示的に示した正面図を図４（ａ）、（ｂ）に示す。なお、この第３の実施の形態においては、前記第２の実施の形態の回転自在な継ぎ手板２２の構成を変えたものであり、その他の構成については、前記第１の実施の形態及び第２の実施の形態と同一であり、説明が重複するため、該第１の実施の形態及び第２の実施の形態と同一のものについては同一の符号を付し、その説明については省略する。
【００３３】
この第３の実施の形態においては、図４（ａ）に示したように、継ぎ手板３１が回転しないように上枠板３に固定させて配設すると共に、左枠板２３に長孔３２を形成し、該左枠板２３と上枠板３とを連結して、該上枠板３に左枠板２３の連結部をスライド自在に連結させたものである。なお、上枠板３と右枠板２４との連結部並びに下枠板４と左枠板２３及び右枠板２４の連結部については、前記左枠板２３と上枠板３との連結部と同様であるため、説明は省略する。
【００３４】
また、図４（ｂ）に示したように、上枠板３の端部に垂下部３３を形成し、該垂下部３３に長孔３４、３５を形成し、該上枠板３と左枠板２３とをＬ字状に形成された継ぎ手板３６により連結部させても良い。
【００３５】
要するに、上枠板３と下枠板４との各両端部に継ぎ手板３１、３６を介して、該上枠板３と下枠板４との近傍の内側にクランプ２９をそれぞれ配設した左枠板２３と右枠板２４とをスライド自在に連結させ、該左枠板２３と右枠板２４とをそれぞれ上方にスライドさせ内側に寄せた状態にし、被処理板材２と下枠板４との重量により、該左枠板２３と右枠板２４とが下側方向にスライドし外側に移動または開く構成にして、該被処理板材２に外側方向（左右方向）の張力を付与させて、該被処理板材２を保持できれば良いのである。
【００３６】
本発明の第４の実施の形態に係る被処理板材保持治具４１を略示的に示した正面図を図５に示す。なお、この第４の実施の形態においては、前記第２の実施の形態の上枠板３に懸吊保持手段４２を配設し、下枠板４に回転自在なクランプ４３を配設させ、回転自在な継ぎ手板２２の形状を変えたものであり、その他の構成については、前記第１の実施の形態及び第２の実施の形態と同一であり、説明が重複するため、該第１の実施の形態及び第２の実施の形態と同一のものについては同一の符号を付し、その説明については省略する。
【００３７】
この第４の実施の形態においては、前記第２の実施の形態の上枠板３の略中央部に懸吊保持手段４２を配設し、下枠板４の略中央部に回転自在なクランプ４３を配設させたものである。該懸吊保持手段４２と回転自在なクランプ４３とは、第４の実施の形態の被処理板材保持治具４１に配設させることに限定されるものでなく、前記第１の実施の形態または前記第３の実施の形態の被処理板材保持治具に配設させても良い。また、回転自在な継ぎ手板２２は、前記第２の実施の形態の形状に限られるものではなく、この第４の実施の形態に示したの回転自在な継ぎ手板２２ａのように形成しても良い。
【００３８】
この懸吊保持手段４２は、図６（ａ）の正面図と、図６（ａ）のＢ−Ｂ線に沿う断面図である図６（ｂ）とに示してあるように、懸吊保持手段４２の長さ方向と直角且つ上枠板３と平行な方向に錘板４４を配設させたものである。なお、該懸吊保持手段４２においては、錘板４４を配設させた以外の構成は、前記回転自在なクランプ６ａ、６ｂ、７ａ、７ｂと同様であるため、同一のものについては、同一の符号を付し、その説明については省略する。
【００３９】
懸吊保持手段４２は、上枠板３に形成された長孔４５によって、該上枠板３に回転及びスライド自在に配設されているが、該懸吊保持手段４２に配設された錘板４４により、該懸吊保持手段４２に挟持された被処理板材２を引き上げるように、常に該被処理板材２に対して上側方向に張力を付与している。
【００４０】
また、回転自在なクランプ４３は、図７に示してあるように、下枠板４に形成された長孔４６によって、該下枠板４に回転及びスライド自在に配設されており、該回転自在なクランプ４３に挟持された被処理板材２を引き下げるように、常に該被処理板材２に対して下側方向に張力を付与している。なお、該回転自在なクランプ４３においては、前記回転自在なクランプ６ａ、６ｂ、７ａ、７ｂと同様の構成であるため、同一のものについては、同一の符号を付し、その説明については省略する。
【００４１】
このように、上枠板３に懸吊保持手段４２を配設させ、該懸吊保持手段４２により被処理板材２を挟持することにより、該被処理板材２に上側方向の張力を付与した状態で、該被処理板材２を保持することができ、また、下枠板４に回転自在なクランプ４３を配設させ、該回転自在なクランプ４３により被処理板材２を挟持することにより、下側方向にも張力を付与できるようになるのである。
【００４２】
なお、上枠板３と下枠板４と左枠板２３と右枠板２４とは、例えば、ステンレス、銅、チタンまたは合成樹脂等で形成することができる。
【００４３】
【発明の効果】
以上説明したように、本発明の第１の発明に係る被処理板材保持治具は、被処理板材を垂直に懸吊する治具であって、前記被処理板材の一辺よりも長尺で且つ両端部近傍に回転自在なクランプをそれぞれ配設した上下の枠板からなり、該上下の枠板に配設された回転自在なクランプをそれぞれ内側に傾斜させて前記被処理板材の上側と下側の両角部近傍をそれぞれ挟持させ、前記被処理板材と下枠板との重量により各クランプが外側に開くように回転して被処理板材に外側方向の張力を付与する状態で保持する構成にしたことにより、被処理板材に孔等を形成させる必要がなく、該被処理板材に平面保持力（張力）を付与した状態で簡単に保持でき、例えば、薄型・軽量化されたプリント配線基板等の被処理板材に化学めっき、電解めっき、電解脱脂または電解エッチング等の処理をする場合であっても、該被処理板材に反り・曲がり等が生じないようにできるという優れた効果を奏する。

【００４５】
更に、第３の発明に係る被処理板材保持治具は、被処理板材を垂直に懸吊する治具であって、前記被処理板材の一辺よりも長尺な上下の枠板と、該上下の枠板の各両端部に継ぎ手板を介してスライド自在に連結され且つ上下両端部近傍の内側にクランプをそれぞれ配設した左右の枠板とからなり、該左右の枠板をそれぞれ上方にスライドさせ内側に寄せた状態にして各クランプで前記被処理板材の左右の両角部近傍をそれぞれ挟持させ、前記被処理板材と下枠板との重量により前記左右の枠板がそれぞれ下方にスライドし外側に移動または開いて被処理板材に外側方向の張力を付与する状態で保持する構成にしたことにより、被処理板材に孔等を形成させる必要がなく、該被処理板材に平面保持力（張力）を付与した状態で簡単に保持でき、前記第１及び第２の発明と同様の効果を奏する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to, for example, a jig for holding a plate material to be processed, which is vertically suspended with tension applied to the plate material to be processed, such as a printed wiring board.
[0002]
[Prior art]
Conventionally, when performing processing such as chemical plating, electrolytic plating, electrolytic degreasing or electrolytic etching on a plate material to be processed, for example, a printed wiring board, the printed wiring board is held by a jig in a form of being sandwiched by a frame or the printing is performed. The above processing is performed by holding the upper part of the wiring board with a clip or the like.
[0003]
As a jig in which the printed wiring board is sandwiched by a frame, for example, a jig body including a holding member and a width determining adjustment member, a covering portion covering the holding member, and a side wall facing the jig member A printed circuit board comprising: a locking member comprising a locking portion having a substantially U-shaped cross section with a holding space formed therebetween; and a holding member which covers the locking member and is provided rotatably around a pivot. There is a plating jig (see Patent Document 1).
[0004]
The known technique of Patent Document 1 is a jig for plating a printed circuit board that has a simple structure, facilitates attachment and detachment of the printed circuit board, and fixes the printed circuit board.
[0005]
Since the printed wiring board is required to be small and light in electronic equipment and the like on which the printed wiring board is provided, the printed wiring board is also thin and light, for example, polyimide or 0.04 t epoxy. Materials may be used.
[0006]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 2000-290797 (Claim 1, FIG. 1)
[0007]
[Problems to be solved by the invention]
However, in the known technique of Patent Literature 1, the printed circuit board is simply held, and no flat holding force (tension) is applied to the printed circuit board. Therefore, the chemical plating, the electrolytic plating, the electrolytic degreasing, or the electrolytic plating is performed. When performing processing such as etching, the printed circuit board is warped or bent, and particularly when the thinned and lightened printed circuit board is processed, the warpage or bending is increased. There are points.
[0008]
