摘要

本研究首先使用ANSYS軟體進行樣品生產時的應力分佈分析，然後進行排氣法及墨水流動方法來找出漏氣點與漏氣路徑，將實驗結果與分析結果相比較，推測可能的原因為何。配合差式掃描量熱儀(DSC，Differential Scanning Calorimeter)來分析氣囊式緩衝包裝生產時所使用的塑膠薄膜材料之熔點，來設定適當的模具溫度，以便後續田口法實驗溫度因子水準的設定。之後找出生產線上可操作的重要參數，如模具壓合壓力、送料速度等參數設定，並運用田口實驗設計法的原則、文獻內容、廠商建議等決定控制因子及最佳化製程條件。
由田口實驗結果與相關文獻可得知，模具壓合時間及模具溫度這兩項成形條件是影響整個製程最大的控制因子，並將田口法所得的最佳化製程條件與原本廠商設定之製程條件所生產的樣品進行充氣與烘烤實驗，結果最佳化製程所生產的樣品確實比原本製程所生產的樣品良率高約15 %；而送料速度也因製程最佳化的調整由原本的6 pcs./min.變更為7 pcs./min.，使產量每天可增加27 %。

In this study, used ANSYS software to analysis the stress distribution in the process of the air cushion bag packaging. Then to find the leak and leak paths by using the methods of the exhaust and ink flow. Last, we can compare the results between the analysis and the experimental, then to speculate which reason is possibly.
Then we can use the DSC (Differential Scanning Calorimeter) to find the melting point of the plastic material which used to product the air cushion bag packaging. When the melting point was found, we can set the mold working temperature. Then to find each other parameters, such as mold pressing pressure, conveyor speed. Last, refer to the guidelines of the Taguchi experimental design, the references and the suggest from the manufacturer to determine control factors and the optimization condition.
By the Taguchi experimental results and references can be learned, the mold pressing time and the mold temperature are two control factors, which were the greatest impact in the process of the airbag cushion packaging. Then, we can compare the yield rate between the optimization condition and the original condition. The result is that the yield rate was improved 15 % from original condition to optimization condition. By using the optimization condition, the conveyor speed was enhanced from 6 pcs./min to 7 pcs./min. so the productivity can be increased 27 %.
