新式超音波輔助光學玻璃熱壓機台之研發

Abstract

玻璃熱壓成形技術是玻璃光學元件重要的製程方式，近年來由於玻璃熱壓成形技術的蓬勃發展，大幅降低了玻璃光學元件製程成本。同時超音波振動輔助已經廣泛應用於塑性加工，藉由摩擦力的降低、材料溫度升高…等現象，使得材料成形性提高，提昇加工精度及降低成本。 本研究嘗試研發一新式超音波輔助光學玻璃熱壓機台，能夠準確地控制並紀錄溫度及力量等成形參數。再使用此機台進行超音波輔助光學玻璃熱壓實驗，並調整其成形參數以製作出更佳的光學玻璃產品。而使用此新式機台進行的超音波輔助熱壓製程，之後將可應用於光學玻璃產業中，製作出品質更佳的光學玻璃產品。

Glass hot embossing is an important technique for optical elements fabrication in recent years. It is generally used to manufacture optical lenses with the advantages of low-cost and steady quality. In the same time, the ultrasonic assisted manufacture is widely used in plastic forming in recent years. This technique can raise the precision of products as well as reduce the cost of manufacture. In this research, a novel ultrasonic assisted hot embossing apparatus is developed for manufacturing optical glass. This apparatus is capable of adjusting and recording both temperature and force accurately. By using this apparatus, the proper manufacture parameters are obtained to accomplish better optical glass products. This novel apparatus with optimal ultrasonic hot embossing procedure can be applied to produce better optical structure on the optical glass in the industry.
