摘要:	摘要本文將著眼於導管消融術導管器械中的”運動控制線組件” 的組裝線改善，該器械操作特性是透過2.0-3.5cm的靜脈血管到達心臟，可想而知其器械運動機構及內部零件設計必須是緊湊與細微的，且由於醫療器材在製造過程中必須符合特定的醫療規範與嚴格的品質要求之特性，所以此產業大多還是依賴人工進行組裝，現況瓶頸在於該產品細微，造成對作業人員的視力、手穩度與技術經驗的要求極高，對人力資源需求也變高，在現今人力缺乏的環境下無疑是雪上加霜。本研究是運用線切割機自動穿線系統中的眼模機構原理改善治具設計，輔以萃思(TRIZ)理論找出運動控制線組件組裝流程的不良因子及改善機會點，進行組裝線操作介面、流程之設計改善，達到縮減工作週期、組裝流程及生產資源需求，並減少對於作業人員經驗與技術的依賴，使生管及製造單位在作業人員排班調度上更加具有彈性，最終達到既能減少資源需求又能提升產能及品質之目標。研究結果除達成研究目的所設立的(1)縮減60秒組裝工作週期、(2)減少對作業人員能力的依賴、(3)將兩道焊接工序整合為一的三項目標外，最終讓雷射焊接設備及作業人員的需求同步縮減。;Abstract This thesis will focus on the improvement of the "motion control of Wire assembly” assembly line in the catheter device for catheter ablation. The operating characteristic of the device is to reach the heart through the 2.0-3.5cm venous blood vessel. It is conceivable that the design of the device′s motion mechanism and internal parts should be compact and subtle, and because medical devices must comply with specific medical specifications and strict quality requirements during the manufacturing process, currently most of the industry still relies on manual assembly. The requirements for eyesight, hand stability and technical experience are extremely high, and the demand for human resources has also become higher. In today′s environment of lack of manpower, it is undoubtedly worse. This research is to use the principle of the eye mold mechanism in the automatic threading system of the wire cutting machine to improve the design of the fixture, supplemented by the TRIZ theory to find out the bad factors and improvement opportunities of the assembly process of the motion control line components, and to carry out the operation interface of the assembly line , Process design improvement, to reduce the work cycle, assembly process and production resource requirements, and reduce the dependence on the experience and technology of operators, so that the production management and manufacturing units are more flexible in the scheduling of operators, and finally achieve both The goal of reducing resource requirements and improving production capacity and quality. In addition to achieving the three goals set for the purpose of the research (1) III reducing the 60-second assembly cycle time, (2) reducing the dependence on the ability of the operator, and (3) integrating the two welding stations into one, the research results finally allowed demand for laser welding equipment and operators has been reduced simultaneously.
