In fact, many products such as the battery cases of computer and cell phone, the adaptor and the connector of USB transmission line, all have such necessities. In general, in order to avoid the defective condition caused by man-made or dust, the electronic circuit and component will be covered by plastic case. The plastic case could protect the product and make its function work well. The user can not open the case easily either. In the real ultrasonic plastic welding process, 1%~3% production defective rate will be reasonably considered and set by user. The main reason is that too many possible variables will affect the product’s quality in the manufacturing process. For examples, the property of upper and lower cases, man-made error, welding energy, pressure, hold time, press speed, amplitude, delay time, etc., all possibly influence the welding quality and then have a decisive impact to the product. Thus, for a large amount of products, even 1% defective rate will result in a big loss to the company. Sometimes, the loss could reach to ten millions or a billion dollars per year. Therefore, the research of this thesis aims to employ the intelligent control techniques into the study of precise control for the ultrasonic plastic welding machine. A precise control mechanism for the ultrasonic plastic welding process is expected to be developed. To the cases with various plastic materials, an optimal control design and welding process could be created. Based on such intelligent control mechanism, not only the cost of company can be decreased, but also the competitiveness of business could be increased.

碩士 === 義守大學 === 電機工程學系 === 105 === Due to the fast development of electronic and communication technologies, the protection of electronic product has become more and more important and indispensable, especially for the products need to be protected and forbidden to open. In fact, many products such as the battery cases of computer and cell phone, the adaptor and the connector of USB transmission line, all have such necessities. In general, in order to avoid the defective condition caused by man-made or dust, the electronic circuit and component will be covered by plastic case. The plastic case could protect the product and make its function work well. The user can not open the case easily either.
In the real ultrasonic plastic welding process, 1%~3% production defective rate will be reasonably considered and set by user. The main reason is that too many possible variables will affect the product’s quality in the manufacturing process. For examples, the property of upper and lower cases, man-made error, welding energy, pressure, hold time, press speed, amplitude, delay time, etc., all possibly influence the welding quality and then have a decisive impact to the product.
