鋼珠常出現在日常生活的各個環節中,隨著精密工業的發展,對鋼珠品質的要求也越來越高,然而鋼珠表面瑕疵是造成鋼珠品質不良的主因。鋼珠品質的不良,造成的問題若發生在工業機具以及交通工具上,會造成商業上嚴重的損失或者人員傷亡,因此鋼珠表面瑕疵的檢測是十分重要的議題。 自動光學檢測被各種產業界用來取代人工檢測,因自動光學檢測可以克服人工檢測的缺點,為一種客觀、穩定而且具效率性的檢測方式,本論文將針對鋼珠表面瑕疵開發一套自動光學檢測系統。TRIZ(創新構思問題解決法)為近年來熱門且具實用性的一種創新思考方法,TRIZ被廣泛運用於解決各種工程上的問題,本論文運用TRIZ分析開發自動光學檢測系統中所遭遇的問題,利用TRIZ矛盾矩陣,依照工程參數及相對應的創新原則構思解決方案。 本研究目的為開發一套鋼珠表面瑕疵自動光學檢測系統,實驗結果顯示,本自動光學檢測系統,可以達到良好的瑕疵檢出率(92.75%)、高檢測速度(一秒檢測四顆鋼珠)、高可靠度(連續運作48小時)。
Steel ball is found in every aspect of daily life, with the precision industry, the quality of the ball higher and higher demands, but the steel ball surface defect is caused by poor quality reasons. Steel ball poor quality causing problems in the event of industrial machinery and transport will lead to serious business losses or casualties, the steel ball surface defect detection is very important issue. Automatic optical inspection has been a variety of industries to replace the manual inspection, because automated optical inspection can be overcome of manual inspection of defects, is an objective, stable and efficient way of testing. TRIZ popular in recent years possessed practical method, TRIZ has been widely used in solving engineering problems, this paper analyzes the use of TRIZ to develop automated optical inspection system, the problems encountered. The purpose of this study was to develop a steel ball surface defect automated optical inspection system, experimental results show that the automated optical inspection system, can achieve good defect detection rate (92.75%), high detection speed (a second test four ball), high stability (48 hours continuous operation).
