碩士 === 國立雲林科技大學 === 機械工程系 === 104 === Rubber and plastics had been developed for a long history, the related products are used in our daily life, such as tires and folders. The automatic producing technology is developed by the improving of the precision mechanical technology. The production rate and accuracy are also improved. Therefore, the traditional process measurement technology are now replaced by automation inspection technology. The study is based on optoelectronic method of detecting to establish three kinds of measurement system. First, Laser displacement sensor and rotary encoder make up an overlapping width measurement system to measure plastic overlapping width. Being able to measure rapidly is the advantage of this system. Second, Laser displacement sensor is used to establish plastic measurement system to measure rubber’s thickness attached in polyester. High efficiency of measuring thickness is the advantage of this system. Third, using infrared light and infrared light sensors to establish an infrared thickness measurement system to measure the thickness of the polypropylene film. This system has some advantages such as a low cost and high accurate precision measurement. For the verification of the system features, the repeatability analyses have been performed. By the commercial measurement instrument, the accuracy of the proposed system has been verified. According to the experiment results, the repeatability of the measurement system for the width measurement of overlapped rubber layer is about 0.287 mm and the average error of the commercial measuring system is about 0.294 mm. The repeatability of the measurement system of rubber thickness is about 0.002 mm and the average error of commercial measuring system is about 0.005 mm. The repeatability of the infrared thickness measurement system is about 0.0009 mm and the average error of commercial measuring system is about 0.0056 mm.
