Abstract
Description
また、例え複数の金属導入装置を設けて、各辺に沿って移動するように構成したとしても、ガラス板の全体のサイズが変更された時には、それらの金属導入装置を、夫々設置変更して夫々の移動経路を変更しなければならず、これも、多くの手間と時間を要するという問題点がある。
しかも、第1辺と第2辺とが交差する第1角部と、第3辺と第4辺とが交差する第2角部とは、夫々充填した金属材料が凝固する前に、別の金属導入装置による金属の充填を開始して互いに交差する2辺に金属が充填されるために、各角部における加熱管理にかける手間を少なくできる。
その上、ガラス板のサイズが変更されたとしても、第1金属導入装置及び第2金属導入装置の移動経路及び金属導入方向を変更する必要がない。
従って、ガラス板の周縁部における封止に手間と時間を少なくできる。
しかも、第1辺の他端部及び第2辺の他端部に充填した金属材料が凝固する前に、第2角部で交差する2辺の内の第3辺の他端部から第1金属導入装置を第2角部に向けて金属材料を充填しながら移動すると共に、第2金属導入装置をもう1つの第4辺の他端部から第2角部に向けて金属材料を充填しながら移動させることにより、4つの各角部では、特に加熱維持しなくても第1金属導入装置及び第2金属導入装置による連続した溶融金属の充填作業ができ、より短時間で両ガラス板の全周縁部の封止ができる。
また、ガラス板のサイズが変更されたとしても、第1金属導入装置及び第2金属導入装置の移動経路及び金属導入方向を変更する必要がない。
従って、ガラス板の周縁部における封止により一層手間と時間を少なくできる。
その上、ガラス板における4つの角部で、夫々特に加熱維持しなくても第1金属導入装置及び第2金属導入装置、第3金属導入装置、第4金属導入装置による連続した溶融金属の充填作業ができ、より短時間で両ガラス板の全周縁部の封止ができる。
図1において、ガラスパネルPは、対向する一対のガラス板1A,1Bと、一対のガラス板1A,1B間に、マトリックス状に一定のスペーサーピッチPdで複数の柱状のスペーサー2を介在させることにより形成される間隙部Vと、間隙部Vの周縁部V1をシールする周辺封止用金属材料3と、一対のガラス板1A,1Bの内の一方のガラス板1Aを貫通する吸引孔4とを有する。吸引孔4は、その吸引孔4の周りにまで至って覆う吸引孔封止用金属材料15で封止されてある。
まず、フロートガラスから成る所定の厚さの2枚のガラス素板(不図示)を所定の寸法、例えば、1200mm×900mmに夫々切断し、同一形状且つ同一サイズであるガラス板1A,1Bを準備し(ステップS31)、ガラス板1Aに、その四隅のうちいずれか1つの近傍において吸引孔4をドリル等によって穿設する(ステップS32)(穿設ステップ)。
図4において、金属導入装置5は、高部6aと、高部6aより低い低部6bとを有して段差状に形成された定盤6を有し、高部6aにおいて一対のガラス板1A,1Bを保持すると共に、低部6bにおいて一対のガラス板1A,1Bにハンダを供給する供給塔7を保持する。段差状定盤6の低部6bには、上記一対のガラス板1A,1Bに沿って2本のレール部材12が配され、上記供給塔7はレール部材12上を走行する移動機構13の上に載置されている。
つまり、屈曲部8Aを有する導入板8の移動によって、バネ作用を有する屈曲部8Aが、ガラス板の表面を軽く擦りつけるようになり、ハンダのガラス面への付着性をより向上させて、間隙部Vの気密性が確実化される効果を発揮できるようになる。
これにより、一対のガラス板1A,1B間に形成された間隙部Vが密閉される。
尚、Snを選択した場合、90%以上あればよく、また、Cuを添加したSnの場合、Cuの量は、0.1%以下にする必要がある。
さらに、吸引孔封止用金属材料15は、周辺封止用金属材料3と異なる成分のハンダを用いても良い。
尚、吸引孔封止用金属材料15または周辺封止用金属材料3にTi(チタン)を含有させることにより、ガラスの密着性が向上する。
さらに、一対のガラス板1A,1Bの組成についても、ソーダ珪酸ガラス、ソーダ石灰ガラス、ホウ珪酸ガラス、アルミノ珪酸ガラス、各種結晶化ガラス等を使用することができる。
また、突出部16の突出部厚みDgは0.1~20mmである。好ましくは、0.1~10mmである。

尚、第3角部Bと第4角部Dで金属材料が凝固しない内に、第3角部Bで第1金属導入装置5Aと第3金属導入装置5Cとが金属材料を充填終了し、且つ、第4角部Dで第2金属導入装置5Bと第4金属導入装置5Dが金属材料を充填終了するためには、少なくとも4辺の内、長い辺から優先的に金属材料の充填を開始したほうが良い。
図10に示すように、夫々矩形の一対のガラス板1A、1B間に、スペーサー2を配設して間隙部Vを形成し、溶融した金属材料を両ガラス板1A、1Bの周縁部V1に充填してガラス板1A、1Bと金属材料とを直接接合し、間隙部Vを気密に封止するガラスパネルの製造方法であって、ガラス板の第1角部Aで交差する第1辺Vab及び第2辺Vadに沿って各別に移動して、溶融した金属材料を両ガラス板1A、1Bの周縁部V1に充填する第1金属導入装置5Aと第2金属導入装置5Bとを第1角部Aに設けると共に、第1角部Aと第1角部Aに対し対角に位置するガラス板の第2角部Cの延長線上で、且つ、第1角部Aに対して第2角部Cよりも離れた箇所に、第2角部Cで交差する第3辺Vbc及び第4辺Vcdに沿って各別に移動して、溶融した金属材料を両ガラス板1A、1Bの周縁部V1に充填する第3金属導入装置5Cと第4金属導入装置5Dとを設ける。次に、溶融した金属材料を両ガラス板1A、1Bの周縁部V1に充填するのに、第1アライメント22の位置で両ガラス板1A、1Bを位置合わせした後に、第1角部Aから第1金属導入装置5Aを第1辺Vabの他端部に向けて金属材料を充填しながら移動させる。また、第1角部Aに充填した金属材料が凝固する前に、その第1角部Aから第2金属導入装置5Bを第2辺Vadの他端部に向けて金属材料を充填しながら移動させ、両ガラス板1A、1Bを第1角部Aと第2角部Cの延長線上にコンベア20によって、平行移動させる。そして、第2アライメント23の位置で両ガラス板1A、1Bを固定して、第2角部Cから第3金属導入装置5Cを第3辺Vbcの他端部に向けて金属材料を充填しながら移動させる。また、第2角部Cに充填した金属材料が凝固する前に、その第2角部Cから第4金属導入装置5Dを第4辺Vcdの他端部に向けて金属材料を充填しながら移動させる。
特に前提条件として、周辺封止用金属材料3に対する複数の金属導入装置の供給速度が同じで、ガラスパネルPの4つの周辺の内、長辺部を短辺部よりも優先的に導入板8による通過が先になるようにした場合、生産効率が向上する。
以下に他の実施の形態を説明する。
なお、以下の他の実施形態において、上記実施形態と同様の部材には同一の符号を附してある。
〈1〉 対向配置する前記一対のガラス板1A、1Bの周縁部V1において、互いに対向する部分夫々に傾斜面を設けた開先部分14を、金属製封止材(周辺封止用金属材料3)の導入板8の挿入に必要となる部分に設けてもよい。
つまり、開先部分14は、溶融した金属製封止材(周辺封止用金属材料3)の導入し始める起点部となる角部分にのみ形成し、その開先部分14の近傍で、起点部となる角部分から縦横2辺に沿って、例えば金属製封止材(周辺封止用金属材料3)の幅を5mmとした場合にそれぞれ50mm離れた箇所に吸引孔4を配設する。
〈2〉 前記開先部分14は、図のように平面状の傾斜面に限らず、曲面状の面であっても良い。
