摘要


在許多電機零組件之加工程序中,因使用高速沖壓的加工方式,其工作環境相當吵雜,不利於長期處於此環境中。噪音對工作人員來說是一項非常大的職業傷害,因此,在此種環境下發展自動化生產技術與自動化檢測技術將是未來之趨勢。 本研究提出以機器視覺及類神經網路之方法來進行產品之品質檢驗。我們利用攝影機擷取產品之數位影像,經過適當的影像前處理後擷取產品之重要特徵。這些特徵將作為類神經網路之輸入來進行物理特性之量測及允收、拒收之判斷。 本論文是以電機零組件S鐵心為研究對象,我們考慮之物理特性包含:(1) S鐵心之內徑;(2) S鐵心積片後之厚度;(3) S鐵心積片後之厚度差。本研究所提出之自動化檢測系統是以工廠所收集到之產品,來進行類神經網路之訓練及測試。實驗結果顯示,本研究所提出之檢驗方法可迅速與精確地量測產品之重要品質特性。

In the manufacturing of electrical components, it is not unusual that some working environments are hazardous and not suitable for human beings. In this situation, development of an automatic inspection system is necessary. In this research, a neural network-based inspection system was developed to perform the automatic inspection of product characteristics. Some important features extracted from the results of image processing were used as the inputs to neural network. In this research, an electrical component, S-rotor, is used as the example to demonstrate the neural network-based inspection system. The quality characteristics considered in this research include: (1) the diameter; (2) the thickness; (3) the difference of thickness at both ends. Data collected from factory were used for training and testing of neural network. Experimental results indicate that the neural network-based inspection system could accurately measure the quality characteristics.
