Abstract:	現今射出成型產業已廣泛進入光學領域，許多零件產品諸如光學鏡片與鏡筒也已由射出成型取代以往傳統之玻璃鏡片，若要使這些產品彼此間相接合的好，則真圓度的影響就顯得更為重要。本研究為探討手機鏡頭內裝載鏡片之光學鏡筒，先是製作U-curve理論充填曲線，再於塑件澆口處埋藏感測節點，並至Moldex3D軟體分析探討各時間點充填與保壓過程之塑件固化情形，接著進入Moldex3D Studio Viewer R17軟體進行真圓度量測，最後使用Minitab軟體針對塑件真圓度特性，使用反應曲面法之Box-Behnken設計與中央合成設計進行參數優化，以求得最佳製程參數，進而改善光學鏡筒之真圓度。結果顯示，Box-Behnken設計較中央合成設計佳，保壓時間、料溫與保壓壓力為較顯著3因子，原始製程參數之光學鏡筒真圓度模擬數值為6.796×10-3mm，使用反應曲面法優化之最佳製程參數，其真圓度數值降低至2.667×10-3mm，改善了約莫60.7%。故反應曲面法確實有助於獲得實驗之最佳化參數與反應結果。 ;The optical industry has widely used injection molding. Many components of product such as optical lenses and lens barrels are manufactured by injection molding instead of traditional glass lenses. The accuracy of the roundness is important for the components to be matched well. In this study, the theoretical U-curve of filling is first made, and then the sensing node was set at the gate of the parts. After that, Moldex3D software analysis was used to discuss the curing process of the parts during the filling and packing stage at various time. Subsequently Moldex3D Studio Viewer R17 software was employed to measure the roundness. Finally, Minitab software was used to optimize the roundness of the parts, and the Box-Behnken design and central composite design of the response surface methodology were used to obtain the optimization of the process parameters. Therefore, the roundness of the optical lens barrel was improved. The results show that Box-Behnken design is better than the central composite deign. The packing time, melt temperature and packing pressure are three significant factors. The roundness of the optical lens barrel of the original process parameters is simulated as 6.796×10-3mm. The process parameter optimized by RSM is reduced to 2.667×10-3mm, which is an improvement of about 60.7%. Therefore, RSM really helps to obtain the optimized parameters and reaction results of the experiment.
