  • 本論文以計算流體力學商用軟體為工具,模擬氣動式無接觸平板抬昇器之流場,探討出風口的形狀、分佈、出風口氣流下傾角度等因素對平板所獲得升力之影響,最後提出一種離散化出風口設計,功能足以抬昇重達0.53N的晶圓,並設計自動防撞機制。

    Using a commercial of fluid dynamics package as research tool, this thesis studies the flow field of non-contact pneumatic lifting devices targeted at flat-plate shaped objects. The aspect ratio of the rectangular airflow outlet, the distribution density of the adopted outlets, and the blowing-down angle of the airflow are examined for their effects on the lifting force produced on the flat-plate objects. The final design resulted from this thesis is a discrete airflow outlet design and distribution capable of lifting a flat-plate shaped silicon wafer with a weight of 0.53N without touching it. The final design includes a mechanism for automatic collision avoidance.
