Description

【０００１】
【発明の属する技術分野】
本発明は、ダイコート機及びダイコート方法に関し、簡単なシステムで、高速で、単板基板に塗工を行うことができるダイコート装置及びダイコート方法に関する。
【０００２】
【従来の技術】
ダイコート方式による単板状塗工対象物への塗工における最大の問題点は単板上に塗工する場合、塗りはじめと終わりの膜厚制御が容易ではないことである。
このため、多くの既存機は液の供給量の高精度制御が必要であり、また、エッジの塗工部を洗い流す方法をとっており、そのための洗浄装置部を持つ。また基板枚に塗工を行うため生産速度が遅い。
【０００３】
【発明が解決しようとする課題】
この発明の目的は上述した従来技術の不都合を解決し、簡単なシステムで、高速で、単板基板に塗工を行うことができるダイコート装置及びダイコート方法を提供する。
【０００４】
【課題を解決するための手段】
請求項１記載の本発明は、塗工を行うダイコーターにおいて、単板の塗工対象基板を一直線上に連続的配置する基板設置ステージと、このステージに塗工対象基板を固定、設置するための治具と、ステージ上に設置されたこれらの基板に塗工を行うため移動するダイヘッドとを具備し、前記治具のうち、前記ダイヘッドにより塗工される部分は濡れ性が前記塗工対象基板と同じになるようにすることを特徴とするダイコーティング装置である。
【０００５】
請求項２記載の本発明は、塗工を行うダイコーターにおいて、治具のうち、前記塗工対称基板と接する側面部は、密着性を有するものであることを特徴とする請求項１に記載のダイコーティング装置である。
請求項３記載の本発明は、ダイコーターによる塗工方法において、単板の塗工対象基板を一直線上に連続的配置する基板設置ステージ上に塗工対象基板を連続的に、濡れ性が前記塗工対象基板と同じである治具に固定し、ダイヘッドをこの基板上を走査させることにより単板塗工対象物を複数枚連続で塗工することを特徴とする塗工方法である。
【０００６】
【発明の実施の形態】
本発明において塗工対象基板とはガラス基板、プラッスチック基板などであるが、これらに限るわけではない。
図１に示すシステムによって塗工単板対象物に対する連続塗工を行う。塗工単板対象物４のステージ２への移動及び塗工後の単板の取り出しはローダー３で行う。図１の塗工方向（白抜き矢印）に複数対象物を設置する。この複数の塗工単板対象物上をダイヘッド１が走査、塗工する。塗工液は供給系により供給される。
塗工方向（図１、白抜き矢印）への複数対象物の設置方法の詳細は以下の通りである。図２（Ａ）において、７で示した塗工単板対象物を塗工方向に連続的に配置するための治具を固定治具と今後示す。塗工単板対象物を図のように配置し、固定治具を塗工単板対象物間に配置する。この固定治具を用いて塗工単板対象物を塗工方向に固定する（図２Ｂ）。塗工方向に一直線上に配置された塗工単板対象物（郡）はダイヘッド１を白矢印方向に走査し塗工される。固定治具のうち斜線で示した部分は濡れ性が塗工対象物と同じになるようにする。また、固定治具のうち６と８の側面部は塗工対象物を固定するため、密着性の高い材料をもちいる。また、治具７は塗工対象物４と紙面垂直方向の段差がなく、平面平滑度も同程度にする。
治具洗浄ユニット６は塗工により汚染された固定治具７（特に８部分）を洗浄するものである。洗浄方法としては、塗液を親溶媒で洗う方法であれば何でもよく、機械・機構等は特に限定しない。
【０００７】
