LCD面板垂直輸送時之動態氣流分析

Abstract

本研究應用數值模擬套裝軟體STAR-CD，模擬LCD面板垂直輸送時之流場分佈，垂直通道上置有風機濾網機組(FFU)提供均勻氣流，並直接吹向面板以防止微塵粒子附著於玻璃面板上；面板下方則有排氣管道以排出空氣，主要是觀察面板在垂直輸送過程時，面板相對壓力與支撐架輸送面板速度是否會造成面板產生飄浮現象。 綜合模擬結果與分析，支撐架輸送面板速度較慢時，面板受流場影響的相對壓力，並不會使面板產生飄浮現象，因為面板上方的壓力大於面板下方的壓力；而排氣管道的寬度增加則會適當的改善面板的飄浮現象。

A commercial code is adopted in this study to simulate the flow field when transporting the LCD panel vertically in a vertical channel. some FFUs are installed on the top of the vertical channel to prevent particles stay on the panels. Exhausting pipes are installed to discharge the gas. Mainly purpose in this study is to obtain the relative pressure or the velocity of supports will result in the panels float. When the velocity is slow, the pressure difference will not cause the panels float. And increasing the width of the exhausting pipes will improve the floating.
