Description
Summary:碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 98 === As the progressive of 3C industry made many convenient products, glass substrate has become one of the important parts for the mobile phone panel. In this thesis, an image measurement system built by image processing and geometrical measurement theory has been developed for the dimensional measurements of a glass substrate including length, width and chip height which cannot be measured by contact measurement method. To verify the measurement performance of the system, repetitive analysis of the image measuring system has been carried out. By the comparison measurement between the developed system and the measuring microscope, the accuracy can be proved. The experimental results show that the repeatability of dimensional measurements is less than ±0.003mm and the corresponding accuracy is less than 0.011mm. The angle repeatability of glass face substrate is less than ±0.44° and the accuracy is 1.03°. The repeatability and accuracy of the glass substrate length and width are ±0.025mm and 0.046mm. The repeatability and accuracy of the chip height of the glass substrate edge are ±0.006mm and 0.01 mm.
