摘要
隨著在全球市場上手機市場的成長非常快速。台灣於業者於手機零組件市場的佔有率也逐漸擴大，雖然國內製造技術不斷的進步亦領先其他國家，但卻受限於檢驗品質與檢驗效率的無法提升而使產業發展受到瓶頸，並逐漸受到中國大陸競爭者的威脅。
本研究主要目的為開發設計一可自動化的手機內部鏤空防磁元件的檢測設備，由於功能要求此元件令平面度玩其主要檢驗項目。目前業界大都使用人工檢驗方式，檢驗品質不穩定且產能受限，研究中利用誤差分析設計與控制技術，發展了一低成本可靠度佳且可自動篩選合格與不合格件的檢驗設備。首先，於設計之初先行針對此類防磁元件本身可能之誤差形式與種類進行分析，再依據其誤差表現特性設計可快速檢驗的方式，進而規劃設計檢測設備的功能與結構。未能使檢測設備達到所要求的檢驗精度，研究中分別探討設備零件的設計、製造、組裝等可能的誤差組合，在考慮檢測精度與製造成本情形下，以統計法設計重要零件的公差，目標以開發一成本低廉及性能可靠的機型為主，進而設計出不失其檢驗性能以及最低成本的檢驗自動化設備。
為檢驗所開發設備的可靠度，研究中進行分類的檢驗精度測試實驗與統計分析。測試結果證明本研究所開發的設備可100﹪檢驗出不合格元件並予以分類，檢測穩定性亦佳，可節省人力並有效提升五倍以上的檢驗速率。

Abstract

In the global market, the need of cellular phone grows rapidly. In the meanwhile, Taiwan manufacturers also play more and more important role on supplying the parts for the cellular phone industry. Although Taiwan industry owns the leading technology for manufacturing the parts, the barrier of inspection technology usually limits the market share of Taiwan manufacturing companies, and gradually shortens the advantages of Taiwan companies. In this study, a low-cost automatic inspection equipment that can flexibly adjust the inspection range of flatness and classify the acceptable/unacceptable parts for storage purpose is designed. First, possible error types of the parts were made to be the design basis of the equipment. Subsequently considering manufacturing cost and inspection accuracy, statistical method was adopted to have optimal tolerance design for the critical parts of the inspection equipment. The testing results show that the inspection accuracy and stability of the equipment can achieve very good level. Unacceptable parts can 100% been identified and automatically led to the zone for unacceptable parts. The developed inspection equipment can significantly increase the production rate for the industry.
