Description

部材貼り合わせ装置
　本発明は、２つの部材を接着剤で貼り合わせて接合部材を作成する部材貼り合わせ装置に関する。
　２つの部材、例えば液晶パネルと保護ガラスとを接着剤で貼り合わせて接合部材を作成するものとして、一方の部材の貼り合わせ面の一部に接着剤を塗布し、２つの板状部材の貼り合わせ面を対面させて接着剤を他方の部材に接触させ、２つの板状部材を加圧して接着剤を展延させるものがある（例えば、特許文献１参照）。
　また、２つの部材、例えば液晶パネルと保護ガラスとを接着剤で貼り合わせて接合部材を製造するものとして、一方の部材の貼り合わせ面の一部に接着剤を塗布し、２つの板状部材の貼り合わせ面を対面させて接着剤を他方の部材に接触させ、２つの板状部材を加圧して接着剤を展延させるものがある（例えば、特許文献１参照）。また、接着剤に紫外線を照射して粘度を増加させ、部材間に過不足なく液状樹脂を行き渡らせるようにしたものがある（例えば、特許文献２参照）。
　図１４は、従来の部材貼り合わせ装置の一例を示すブロック図である。部材受け取り装置１１は、貼り合わせ対象の２つの部材を受け取るための治具を有し、部材はその治具の位置に合わせて搭載される。接着剤塗布装置１２は、部材受け取り装置１１で受け取った２つの部材の一方の部材の接合面に接着剤を塗布するものであり、接着剤の厚さが一定となる量の接着剤が塗布される。部材接合装置１３は接着剤塗布装置１２で接着剤を塗布された一方の部材と他方の部材とを接合して接合部材を作成する。そして、部材送出装置１４は部材接合装置１３で作成された接合部材を外部に送出する。なお、部材送出装置１４は一時的に接合部材を貯蔵する貯蔵部を有したものもある。

　しかし、従来のものでは、貼り合わせ対象の２つの部材は、一応、位置決めされて配置されるが、その位置決めは、部材整列装置や受け取り治具などで位置決めされているので、必ずしも精度のよいものではない。従って、２つの部材が精度よく貼り合わせられるには限界があった。２つの部材がずれて接合されると接合部材の品質の低下となる。
　また、従来のものでは、２つの部材を貼り合わせたときに形成される接合部材の厚さが一定となるように貼り合わせが行われるので、部材の厚さにばらつきがあると、２つの部材の間の接着剤の厚さが一定とならずにばらつきを生じることになる。品質の向上のためには２つの部材の間の接着剤の厚さを一定に保つことが要請される。
　例えば、液晶パネルと保護ガラスとを接着剤で貼り合わせタッチパネルを形成した接合部材の場合には、接着剤を介して保護ガラスの押圧力を検知することになるので、接着剤の厚さにばらつきがあると押圧力の検知感度が一定とならない。これにより、押圧力を正しく検知しなかったり誤って検知することが考えられる。
　一方、特許文献１、２のものでは、２つの部材を貼り合わせたとき、接着剤が部材の縁部からはみ出さないようするための対策を特に取っていないので、接着剤のはみ出しを防止するには、接着剤を時間をかけて縁部まで展延させなければならない。すなわち、接着剤が縁部まで展延したときに接着剤がほぼ硬化するように、時間をかけて接着剤を縁部まで展延させなければならない。従って、２つの部材を貼り合わせて形成される接合部材を作成するのに時間がかかる。
　本発明の第１の目的は、２つの部材の貼り合わせの位置決めを精度よく行える部材貼り合わせ装置を提供することである。
　本発明の第２の目的は、２つの板状部材の貼り合わせる接着剤の厚さを一定に保つことができる部材貼り合わせ装置を提供することである。
　本発明の第３の目的は、接着剤が硬化しない状態であっても接着剤が部材の縁部からはみ出すことを防止しつつ接合部材を作成できる部材貼り合わせ装置を提供することである。

　請求項４の発明に係る部材貼り合わせ装置は、請求項１乃至３のいずれか１項の発明において、前記部材接合装置で接合された接合部材の縁部にマスクを介して紫外線を照射し前記接合部材の縁部の接着剤を硬化させる接着剤硬化前処理装置を設け、前記部材送出装置は、前記接着剤硬化前処理装置で縁部の接着剤が硬化された接合部材を取り出し送出することを特徴とする。

　以下、本発明の第１実施形態を説明する。図１は本発明の第１実施形態に係る部材貼り合わせ装置の一例を示すブロック図である。この第１実施形態は、図１４に示した従来例に対し、部材受け取り装置１１で受け取った２つの部材の接合面位置が概ね一致するように整列させる部材整列前処理装置１５、及び搭載したＣＣＤカメラで撮影した２つの部材の画像に基づき、２つの部材の接合面位置が一致するように２つの部材を整列させる部材整列装置１６を追加して設けたものである。図１４と同一要素には同一符号を付し重複する説明は省略する。
　部材整列前処理装置１５は、部材受け取り装置１１で受け取った２つの部材の接合面位置が概ね一致するように整列させる。そして、接着剤塗布装置１２は部材整列前処理装置１５で概ね整列された２つの部材の一方の部材の接合面に接着剤を塗布する。部材整列装置１６は、この接着剤が塗布される一方の部材に対し、接着剤が塗布されていない他方の部材を整列させる。
　そして、部材接合装置１３は、部材整列装置１６で整列された２つの部材の接合面を接着剤を介して接合する。これにより、部材整列前処理装置１５により、部材受け取り装置１１で受け取った２つの部材の接合面位置が概ね一致するように予め整列させておくので、部材整列装置１６による２つの部材の精度のよい整列がより迅速に行える。
　図２は本発明の第１実施形態における部材整列前処理装置１５の一例を示す構成図である。図２では、接着剤が塗布される予定の一方の部材１７ａの図示は省略し、接着剤が塗布されていない他方の部材１７ｂを一方の部材１７ａに対し整列させる場合を示している。
　図２に示すように、部材整列前処理装置１５は、他方の部材１７ｂの４辺をそれぞれを押圧して、図示省略の一方の部材１７ａに他方の部材１７ｂを整列させる押圧具１８ａ～１８ｄを有し、押圧具１８ａ～１８ｄは押圧具駆動部１９ａ～１９ｄで駆動される。押圧具１８ａ、１８ｃにより、矢印Ｂ１、Ｂ２に示すＹ軸方向の位置調整を行い、押圧具１８ｂ、１８ｄにより、矢印Ａ１、Ａ２に示すＸ軸方向の位置調整を行う。

　そして、部材接合装置１３は、部材整列装置１６で整列された２つの部材１７ａ、１７ｂの接合面を接着剤を介して接合する。これにより、２つの部材１７ａ、１７ｂの貼り合わせの位置決めを精度よく行え、２つの部材１７ａ、１７ｂの位置ずれがない品質のよい接合部材を提供できる。
　図３は、本発明の第１実施形態の部材整列装置１６の構成図である。この部材整列装置１６は、複数台のＣＣＤカメラ２０を有する。ＣＣＤカメラ２０はＣＣＤカメラ駆動部２１により、矢印Ａ１、Ｂ１方向（Ｘ軸方向、Ｙ軸方向）に駆動制御され、２つの部材１７ａ、１７ｂの画像を撮影する。２つの部材１７ａ、１７ｂのうちの接着剤が塗布された一方の部材１７ａは、後述の部材接合装置１３により半回転されて他方の部材１７ｂの上方に配置される。接着剤が塗布されない他方の部材１７ｂは、部材接合装置１３の部材搭載台２２に搭載される。部材搭載台２２は吸引ヘッドを有し、他方の部材１７ｂを部材搭載台２２に吸着する。
　部材搭載台２２は駆動装置２３により駆動される。駆動装置２３は、部材搭載台２２をＸ軸方向に駆動するＸ軸駆動部２４、部材搭載台２２をＹ軸方向に駆動するＹ軸駆動部２５、部材搭載台２２をＺ軸方向に駆動するＺ軸駆動部２６、部材搭載台２２をＸ軸回転方向（ＹＺ平面上での回転方向）に駆動するα軸駆動部２７、部材搭載台２２をＹ軸回転方向（ＺＸ平面上での回転方向）に駆動するβ軸駆動部２８、部材搭載台２２をＺ軸回転方向（ＸＹ平面上での回転方向）に駆動するθ軸駆動部２９を有する。
　また、長さが異なる２つのリフレクタ３０が設けられ、リフレクタ３０はＣＣＤカメラ２０で撮影する画像のコントラストを取るために設けられており、リフレクタ駆動装置３１で駆動される。
　図４は、部材整列装置１６による２つの部材１７ａ、１７ｂの位置合わせの説明図であり、図４（ａ）は位置合わせ前の一方の部材１７ａと他方の部材１７ｂとの位置関係の説明図、図４（ｂ）は一方の部材１７ａを他方の部材１７ｂの上方に配置して位置合わせをする状態の説明図、図４（ｃ）は位置合わせ中の２つの部材１７ａ、１７ｂの上面図、図４（ｄ）は位置合わせ後に２つの部材１７ａ、１７ｂを接合した状態を示す説明図である。
　図４（ａ）に示すように、部材接合装置１３は、接着剤が塗布された一方の部材１７ａを把持具３２で把持している。把持具３２は吸引ヘッドを有し、この吸引ヘッドにより一方の部材１７ａを吸着している。一方、部材整列装置１６の部材搭載台２２には他方の部材１７ｂが吸引ヘッドにより吸着され搭載されている。
　この図４（ａ）の状態から、部材接合装置１３の把持具３２のアームを半回転させ、図４（ｂ）に示すように、一方の部材１７ａを他方の部材１７ｂの上方に配置する。そして、ＣＣＤカメラ２０は一方の部材１７ａ及び他方の部材１７ｂを撮影し画像を得る。その際には、リフレクタ駆動装置３１によりリフレクタ３０を駆動し、２つの部材１７ａ、１７ｂの画像のコントラストを取り、図４（ｃ）に示すように、接合面位置の基準位置３３を位置合わせする。例えば、２つの部材１７ａ、１７ｂが液晶パネルと保護ガラスとである場合には、液晶パネルの表示面の隅部を基準位置３３とする。
　この位置合わせは、ＣＣＤカメラ２０で得られた画像に基づき、図示省略の制御装置により図３に示す駆動装置２３を駆動することにより行われる。すなわち、部材搭載台２２をＸＹＺ軸方向及びαβθ軸方向に駆動制御して位置合わせが行われる。そして、位置合わせが行われると、駆動装置２３のＺ軸駆動部２６により、部材搭載台２２を上方に押し上げ、２つの部材１７ａ、１７ｂの接合面を接着剤を介して接合する。
　このように、本発明の第１実施形態では、ＣＣＤカメラ２０を用いて、２つの部材１７ａ、１７ｂの接合面位置が一致するように２つの部材１７ａ、１７ｂを整列させるので、２つの部材の貼り合わせの位置決めを精度よく行え、２つの部材１７ａ、１７ｂの位置ずれがない品質のよい接合部材を提供できる。
　次に、本発明の第２実施形態を説明する。図５は本発明の第２実施形態に係る部材貼り合わせ装置の一例を示すブロック図である。この第２実施形態は、図１に示した第１実施形態に対し、部材受け取り装置１１で受け取った２つの部材の厚さを測定する厚さ測定装置３４と、部材整列装置１６で整列された２つの部材を貼り合わせたときに形成される接合部材の接着剤の厚さが所定厚さとなるように厚さ測定装置３４で測定した２つの部材の厚さに基づいて接合部材の厚さを調整する厚さ調整装置３５とを追加して設けたものである。図１と同一要素には同一符号を付し重複する説明は省略する。
　図５において、厚さ測定装置３４は、部材受け取り装置１１で受け取った２つの部材の厚さをそれぞれ測定する。そして、部材整列前処理装置１５は、厚さ測定装置３４で測定した２つの部材のうちの一方の部材に対し、他方の部材をＸＹ軸方向に位置調整を行い２つの部材の接合面位置が概ね一致するように整列させる。
　接着剤塗布装置１２は、部材整列前処理装置１５で接合面位置が概ね一致するように整列された２つの部材の一方の部材の接合面に接着剤の厚さが一定となる量の接着剤を塗布する。部材整列装置１６は、搭載したＣＣＤカメラで撮影した２つの部材の画像に基づき２つの部材のうちの一方の部材に対し、他方の部材をＸＹＺ軸方向及びαβθ軸方向に位置調整を行い、２つの部材の接合面位置が一致するように２つの部材を整列させる。
　そして、厚さ調整装置３５は、部材整列装置１６で整列された２つの部材を貼り合わせたときに形成される接合部材の接着剤の厚さが所定厚さとなるように、厚さ測定装置３４で測定した２つの部材の厚さに基づいて、接合部材の厚さを調整する。部材接合装置１３は、接合部材の厚さが厚さ調整装置３５で調整された厚さとなるように２つの部材の接合面を接着剤を介して接合し、部材送出装置１４は、部材接合装置１３で接合された接合部材を取り出し送出する。
　このように、厚さ調整装置３５は、２つの部材を貼り合わせたときに形成される接合部材の接着剤の厚さが所定厚さとなるように接合部材の厚さを調整する。すなわち、従来のように、２つの部材を貼り合わせたときに形成される接合部材の厚さが一定となるように接合部材の厚さを調整することに代えて、接着剤の厚さが所定厚さとなるように接合部材の厚さを調整する。そして、部材接合装置１３は、厚さ調整装置３５で厚さが調整された２つの部材の接合面を接着剤を介して接合するので、接着剤の厚さを一定に保つことができ接合部材の品質を向上できる。
　次に、厚さ測定装置３４について説明する。図６は厚さ測定装置３４の構成図である。厚さ測定装置３４は、部材受け取り装置１１で受け取った２つの部材の厚さを測定するものであり、部材１７の厚さを測定する厚さ測定器３６を有する。厚さ測定器３６は、例えばレーザ変位計である。図６では１つの部材１７を図示した場合を示している。
　厚さ測定器３６は、Ｘ軸駆動機構部３７及びＹ軸駆動機構部３８により部材１７の位置まで移動する。図６では、厚さ測定器３６はＹ軸駆動機構部３８に搭載された場合を示しており、Ｘ軸駆動機構部３７によりＹ軸駆動機構部３８を矢印Ａ１方向（Ｘ軸方向）に駆動し、Ｙ軸駆動機構部３８によりＹ軸駆動機構部３８自体を矢印Ｂ１方向（Ｙ軸方向）に駆動して、厚さ測定器３６を移動する。そして、部材１７の厚さを検出し、検出した部材１７の厚さを厚さ調整装置３５に出力する。
　次に、厚さ調整装置３５について説明する。図７は厚さ調整装置３５の説明図であり、図７（ａ）は一方の部材１７ａと他方の部材１７ｂとを貼り合わせる前の状態を示し、図７（ｂ）は一方の部材１７ａと他方の部材１７ｂとを貼り合わせた後の状態を示している。厚さ調整装置３５は、図３に示した部材整列装置１６のＺ軸駆動部２６を駆動制御する部材搭載台駆動制御部３９で構成される。厚さ調整装置３５は、２つの部材を貼り合わせたときに形成される接合部材の接着剤の厚さが所定厚さとなるように、部材搭載台駆動制御部３９で部材整列装置１６のＺ軸駆動部２６を駆動制御して、接合部材の厚さを調整する。
　図７（ａ）では、接着剤４０が塗布された一方の部材１７ａの厚さは部材基準厚さｄ０であり、他方の部材１７ｂの厚さが部材基準厚さｄ０よりΔｄだけ厚かった場合を示しており、一方の部材１７ａは部材接合装置１３の把持具３２により把持され、部材接合装置１３の部材搭載台２２に搭載された他方の部材１７ｂの上方に配置された状態を示している。部材搭載台２２は部材搭載台駆動部３９により部材整列装置１６のＺ軸駆動部２６を駆動制御して上下（矢印Ｃ１方向）に駆動される。
　すなわち、部材接合装置１３は、２つの部材１７ａ、１７ｂの接合面を接合するにあたって、部材搭載台駆動部３９により部材搭載台２２を上方に駆動して、部材搭載台２２に搭載された他方の部材１７ｂを把持具３２により把持された一方の部材１７ａに接合する。その際には、接合部材の厚さが厚さ調整装置３５で調整された接合部材基準厚さとなるように接着剤４０を介して２つの部材の接合面を接合する。
　図７（ｂ）は一方の部材１７ａと他方の部材１７ｂとを貼り合わせた後の状態を示している。一方の部材１７ａ及び他方の部材１７ｂともに部材基準厚さｄ０であるときは、接合部材の厚さが接合部材基準厚さｄａとなるように、厚さ調整をして２つの部材１７ａ、１７ｂを接合する。この場合、接着剤塗布装置１２により塗布された接着剤の量は、接着剤４０の厚さが接着剤基準厚さｄ１となる量であるので、接合部材の厚さを接合部材基準厚さｄａとなるように厚さ調整することで、接着剤４０の厚さを接着剤基準厚さｄ１とすることができる。
　一方、他方の部材１７ｂの厚さが部材基準厚さｄ０よりΔｄだけ厚い場合には、接合部材の厚さの目標値を、接合部材基準厚さｄａよりΔｄだけ大きい接合部目標厚さｄｂとし、接合部材の厚さが接合部目標厚さｄｂ（＝ｄａ＋Δｄ）となるように、厚さ調整をして２つの部材１７ａ、１７ｂを接合する。これにより、接着剤４０の厚さを接着剤基準厚さｄ１とすることができる。
　以上の説明では、他方の部材１７ｂが部材基準厚さｄ０より厚い場合について説明したが、部材基準厚さｄ０より薄い場合にも同様に適用できる。また、一方の部材１７ａが部材基準厚さｄ０より厚い場合や薄い場合にも同様に適用でき、さらに、一方の部材１７ａ及び他方の部材１７ｂの双方が部材基準厚さｄ０より厚い場合や薄い場合にも同様に適用できる。
　このように、第２実施形態では、２つの部材１７ａ、１７ｂを貼り合わせたときに形成される接合部材の接着剤４０の厚さが所定厚さｄ１となるように調整するので、貼り合わせる２つの部材１７ａ、１７ｂの厚さにばらつきがあっても接着剤４０の厚さを一定に保つことができる。これにより、接合部材の品質の向上を図ることができる。
　図８は本発明の第２実施形態に係る部材貼り合わせ装置の他の一例を示すブロック構成図である。この第２実施形態の他の一例は、図５に示した第２実施形態に係る部材貼り合わせ装置の一例に対し、厚さ測定装置３４で測定した２つの部材の複数点での厚さに基づいて、部材の傾きを調整する部材傾き調整装置４１を追加して設けたものである。図５と同一要素には同一符号を付し重複する説明は省略する。
　図８において、部材傾き調整装置４１は、厚さ測定装置３４で測定した部材の複数点での厚さに基づいて部材の傾きを判定し、部材が平坦となるように部材の傾きを調整する。そして、部材接合装置１３は、部材傾き調整装置４１で調整された部材の傾き位置で、２つの部材の接合面を接合する。
　図９は、本発明の第２実施形態に係る部材貼り合わせ装置における部材傾き調整装置による部材の傾き調整の説明図である。部材傾き調整装置４１は、図３に示した部材整列装置１６のα軸駆動部２７、β軸駆動部２８、θ軸駆動部２９を駆動制御する部材搭載台駆動制御部で構成される。部材傾き調整装置４１は、一方の部材を把持した把持具３２や他方の部材を搭載した部材搭載台２２の位置を調整する。
　図９に示すように、部材傾き調整装置４１は、ＸＹＺ空間において、Ｘ軸回転方向（ＹＺ平面上での回転方向）に駆動するα軸駆動部２７、Ｙ軸回転方向（ＺＸ平面上での回転方向）に駆動するβ軸駆動部２８、Ｚ軸回転方向（ＸＹ平面上での回転方向）に駆動するθ軸駆動部２９を、図示省略の部材搭載台駆動制御部で駆動制御することにより、部材１７の傾きやねじれを補正する。
　すなわち、厚さ測定装置３４で測定した部材の複数点での厚さに基づいて部材の傾きを判定し、部材がより平坦となる方向に、α軸方向、β軸方向、θ軸方向を調整する。これにより、部材の傾きやねじれがあっても部材をほぼ平坦に保つことができ、接着剤の厚さをよりほぼ均等に一定に保つことができる。
　次に、本発明の第３実施形態を説明する。図１０は本発明の第３実施形態に係る部材貼り合わせ装置の一例を示すブロック図である。この第３実施形態は、図１に示した第１実施形態に対し、部材接合装置１３で接合された接合部材の縁部の接着剤を硬化させる接着剤硬化前処理装置４２を追加して設けたものである。図１と同一要素には同一符号を付し重複する説明は省略する。
　部材受け取り装置１１で２つの部材を受け取り、部材整列前処理装置１５で２つの部材を接合面位置が概ね一致するように整列させ、２つの部材の一方の部材の接合面に接着剤塗布装置１２により接着剤を塗布し、２つの部材の接合面位置が一致するように部材整列装置１６により２つの部材を精度良く整列させる。そして、部材接合装置１３により一方の部材と他方の部材とを接合する。これにより、接合部材が作成される。
　接着剤硬化前処理装置４２は、部材接合装置１３で接合された接合部材の縁部の接着剤を硬化させるものであり、接合された２つの部材間の接着剤が全体として硬化しない状態であっても、部材接合装置１３で接合部材の縁部の接着剤だけを先行的に硬化させる。これにより、接合された２つの部材間の接着剤が全体として硬化しない状態であっても、接合部材の接着剤が接合部材の縁部からはみ出すことを防止できる。
　図１１は接着剤硬化前処理装置４２の説明図であり、図１１（ａ）は接着剤硬化前処理装置４２の構成図、図１１（ｂ）は接着剤の硬化前処理中の接合部材４７の平面図である。図１１（ａ）に示すように、接着剤硬化前処理装置４２は、接着剤を硬化するための接着剤硬化装置４３を有する。接着剤として、合成接着剤などの高分子固形分が溶媒に溶け込んだ液体状の物質を用いた場合、例えば、紫外線ＵＶが照射されると紫外線の強度に応じて粘度が増加して流動性を失うので、接着剤硬化装置４３としてＵＶ照射装置を用いる。
　接着剤硬化装置４３は、硬化装置駆動部４４を介してＺ軸駆動機構部４５に取り付けられ、マスク４６を介して接合部材４７の縁部に紫外線を照射する。硬化装置駆動部４４は、接着剤硬化装置４３からの紫外線が部材２０の縁部に照射できるように、接着剤硬化装置４３及びマスク４６の位置を調整する。また、Ｚ軸駆動機構部４５は、接着剤硬化装置４３及びマスク４６の縦方向（Ｚ軸方向）の位置を調整する。
　図１１（ｂ）に示すように、接合部材４７のマスク４６がされた部分には紫外線が照射されないので、マスク４６がされていない接合部材４７の縁部の接着剤が先行的に硬化される。従って、接合された２つの部材間の接着剤が全体として硬化しない状態であっても、接合部材の接着剤が接合部材の縁部からはみ出すことを防止できる。
　図１２は本発明の第３実施形態に係る部材貼り合わせ装置の他の一例を示すブロック構成図である。この他の一例は、図１０に示した第３実施形態に係る部材貼り合わせ装置の一例に対し、部材受け取り装置１１で受け取った２つの部材の厚さを測定する厚さ測定装置３４と、部材整列装置１６で整列された２つの部材を貼り合わせたときに形成される接合部材の接着剤の厚さが所定厚さとなるように厚さ測定装置３４で測定した２つの部材の厚さに基づいて接合部材の厚さを調整する厚さ調整装置３５とを追加して設けたものである。図１０と同一要素には同一符号を付し重複する説明は省略する。
　図１２に示すように、部材受け取り装置１１で２つの部材を受け取り、厚さ測定装置３４により部材受け取り装置１１で受け取った２つの部材の厚さをそれぞれ測定する。そして、部材整列前処理装置１５で２つの部材を接合面位置が概ね一致するように整列させ、２つの部材の一方の部材の接合面に接着剤塗布装置１２により接着剤を塗布し、２つの部材の接合面位置が一致するように部材整列装置１６により２つの部材を精度良く整列させる。
　さらに、厚さ調整装置３５は、部材整列装置１６で整列された２つの部材を貼り合わせたときに形成される接合部材の接着剤の厚さが所定厚さとなるように、厚さ測定装置３４で測定した２つの部材の厚さに基づいて、接合部材の厚さを調整する。部材接合装置１３は、接合部材の厚さが厚さ調整装置３５で調整された厚さとなるように２つの部材の接合面を接着剤を介して接合し、部材送出装置１４は、部材接合装置１３で接合された接合部材を取り出し送出する。
　これにより、２つの部材の貼り合わせの位置決めを迅速に精度よく行え、２つの部材の位置ずれがない品質のよい接合部材を提供できる。また、２つの部材を貼り合わせたときに形成される接合部材の接着剤の厚さを所定厚さに一定に保つことができ接合部材の品質を向上できる。さらに、接合された２つの部材間の接着剤が全体として硬化しない状態であっても、接合部材の接着剤が接合部材の縁部からはみ出すことを防止できる。
　図１３は、本発明の第３実施形態に係る部材貼り合わせ装置の別の他の一例を示すブロック構成図である。この別の他の一例は、図１２に示した第３実施形態に係る部材貼り合わせ装置の他の一例に対し、厚さ測定装置３４で測定した部材の複数点での厚さに基づいて部材の傾きを判定し部材をαβθ軸方向に調整して部材が平坦となるように２つの部材の傾きを調整する部材傾き調整装置４１を追加して設けたものである。図１２と同一要素には同一符号を付し重複する説明は省略する。
　部材接合装置１３は、部材傾き調整装置４１で調整された部材の傾き位置で、接合部材の厚さが厚さ調整装置３５で調整された厚さとなるように、２つの部材の接合面を前記接着剤を介して接合する。これにより、図１２に示した第３実施形態に係る部材貼り合わせ装置の他の一例の効果に加え、貼り合わせ部材の傾きやねじれも補正でき、部材の傾きやねじれがあっても、より平坦にできる。従って、接着剤の厚さをほぼ均等に一定に保つことができ、接合部材の品質を向上できる。
　以上、本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。
