Abstract
Description
図1~図3には、実施形態1の製造装置9が概略的に示されている。製造装置9は、スペーサ付きガラス基板100(図4参照)を製造する装置である。
セット工程S1では、第一ガラス基板11、抜き型2、シート材3およびパンチ部4が、この順で下から上に位置するようにセットされる(図1参照)。シート材3は、抜き型2の上面に被せられる。パンチ部4を構成するパンチ41は、シート材3を挟んで、抜き型2が備える貫通孔211の真上に位置する。
スペーサ形成工程S2では、パンチ部4が、下方にむけて一直線状の軌道で打ち込まれる。パンチ部4が下方に打ち込まれることで、柱状のパンチ41が、シート材3の一部31を、抜き型2の貫通孔211を通じて下方に打ち抜く(図2の白抜き矢印参照)。
変位工程S3では、図3に白抜き矢印で示されるように、パンチ部4が上方に移動した後に、第一ガラス基板11とシート材3が水平方向に移動する。本実施形態では、第一ガラス基板11とシート材3の互いの移動方向が同一であるが、第一ガラス基板11とシート材3の互いの移動方向が相違することも有り得る。
組立工程S4では、図4に示されるように、スペーサ付きガラス基板100を構成する第一ガラス基板11の一面111の周縁部に、枠状のシール材13が配される。シール材13は、第一ガラス基板11の一面111上において、複数のスペーサ14を囲んで位置する。
処理工程S5では、第二ガラス基板12が備える通気孔16(図4参照)を通じて、内部空間15が所定の真空度に至るまで減圧されるかまたは内部空間15にガス(乾燥空気、アルゴン等)が供給され、その後に通気孔16が封止される。
図7~図9には、実施形態2の製造装置9が、概略的に示されている。以下において、本実施形態の製造装置9の構成のうち、実施形態1と同様の構成には同一符号を付して詳しい説明を省略し、実施形態1と異なる構成について詳述する。
本実施形態のセット工程S1では、第一ガラス基板11、抜き型2、シート材3およびパンチ部4が、この順で位置するようにセットされる。セット工程S1が完了した時点において、抜き型2が備える複数の貫通孔211と、パンチ部4が備える複数のパンチ41とが、一対一で上下に対向して位置する(図7参照)。
スペーサ形成工程S2では、パンチ部4が備える複数のパンチ41が、シート材3に対して一体に打ち込まれる(図8の白抜き矢印参照)。これにより、抜き型2の複数の貫通孔211を通じて、シート材3の複数の部分311がそれぞれ打ち抜かれる。つまり、本実施形態においては、シート材3から打ち抜かれる複数の部分311が、パンチ部4で打ち抜かれるシート材3の一部31を構成する。
変位工程S3では、実施形態1と同様に、パンチ部4を上方に移動させた後に、第一ガラス基板11とシート材3を水平方向に移動させる(図9の白抜き矢印参照)。本実施形態においても、スペーサ形成工程S2が、変位工程S3を挟んで複数回繰り返し実行される。これにより、複数のスペーサ14を備えるスペーサ付きガラス基板100が製造される。
組立工程S4と処理工程S5は、実施形態1と同様である。両工程S4,S5をさらに経ることで、スペーサ付きガラス基板100を用いて製造されたガラスパネルユニット1が得られる。
実施形態3のガラスパネルユニット1とこれを製造する方法について、図10、図11および図12に基づいて説明する。以下において、実施形態1と同様の構成については、同一符号を付して詳しい説明を省略し、実施形態1と異なる構成について以下に詳述する。
次に、実施形態1~3のガラスパネルユニット1を備えるガラス窓について、説明する。
