擺臂式送料機構組裝與製造性之研究
Study on Design for Assembly and Manufacturing for the swing Type Feeding Apparatus
摘要
本研究之主要目的是發展一套機械裝置之產品設計程序，其主要創意在於整合同步工程、易裝配製造設計原則於設計程序中，藉以縮短產品開發設計時程及增加產品競爭力。整個研究過程包括文獻回顧、最佳化設計程序、裝配導向設計原則及銲接導向設計原則等之建立，並應用於擺臂式送料機構個案。 在本文中，裝配導向設計之原則係根據Boothroyd and Dewhurst 所提出之降低組裝零件數目、裝配方式簡單化與安裝過程標準化原則，對研究個案進行評估。而在製造導向設計方面，則廣泛搜集並建立銲接導向設計原則，並將此原則運用於個案分析。 本研究成果包括建立一含DFA/DFM之設計程序，同時將DFA概念應用於研究個案，其成果是整個擺臂送料機構之進料機構組零件數從原來設計時之26件降至21件，易裝配評比原始設計之42.8%提升至44.8%。此外，亦成功的設計出易銲接之元件。以上成果可供業界參考。

This study aims to develop an effective design procedure for mechanical device. The main concept presented in the study is the integration philosophy Concurrent Engineering with the principles for cost-effective Assembly and Manufacturing in the design procedures to shorten the R&D cycle time and to promote the product’s competitiveness. The contents of study include reviewing the related literature, optimizing the design procedures as well as setting the principles for Design for Assembly and Design for Manufacturing, moreover, a Swing Type Feeding Apparatus, is adopted to examine the feasibility of the design procedures and principles. The results of this study include the development of design procedures with DFM/A concept, and application of the concept to a mechanical mechanism. From this case study, it is show that the amount of the parts needed in this mechanical system can be reduced from 26 to 21; the assembly rating increased from 42.8% to 44.8%. The study also examines the manufacturing ability of the parts with the principles of design for welding. It is expected that the results and method presented are a good reference material for the study of this type of problems.
