Description
そして、前記シリンジのシーリング剤が消尽されれば、使用済のシリンジを取り外して新たなシリンジが装着される。
して、従来のシーリング剤ディスペンサのヘッドユニットについて説明する。
一方、既存のシーリング剤ディスペンサは、シーリング剤が基板上に吐き出される位置と基板上にレーザーが反射される測定点との間の間隔が遠くてシーリング剤の吐き出される基板とノズルとの間の間隔を正確に感知できなかったために、シーリング剤の塗布精密度を高めることができなかった。
第一に、シリンジとノズルとが同軸をなすように取り付けられて、従来とは異なって、直線化されることでシーリング剤の吐出に要求される圧力が低くなることにより、高粘度のシーリング剤を使うことができて、より多様な種類のシーリング剤を使うことができる効果があり、同じ粘度のシーリング剤を使う場合、ノズルから吐き出される吐出圧力が低くなってシーリング剤の塗布性が向上する効果がある。
本発明のシーリング剤ディスペンサの制御方法は、ノズルと基板とを接触させる接触段階と、計測手段が基板との距離を測定する測定点とノズルとの間の距離を測定する測定段階と、前記測定段階で測定された距離が設定値以内であるか否かを判断する判断段階と、前記測定段階で測定された距離が設定値を外れる場合、前記ノズルの位置を補正する補正段階と、そして、前記測定段階で測定された距離が設定値以内である場合、前記ノズルと基板との距離を所定間隔離隔させてシーリング剤の塗布を始める塗布段階と、を含んで構成される。」

Claims (2)
- テーブルに定着された基板に対してシーリング剤を所定のパターンで塗布するシーリング剤ディスペンサ用のレーザー変位センサーであって、
レーザービームを基板に向けて出力する発光部と、
前記発光部から出力されたレーザーの受信される受光部とを含み、
前記発光部及び受光部は、一体型からなり、
前記発光部と受光部との間には、ディスペンサのシリンジの下部が取り付けられる結合孔が形成されたことを特徴とするレーザー変位センサー。 - ディスペンサのシリンジと、シリンジに取り付けられたノズルと、レーザー変位センサーの発光部及び受光部は、同一平面上に位置するように設けられることを特徴とする請求項1に記載のレーザー変位センサー。
