碩士 === 國立臺北科技大學 === 電機工程系研究所 === 99 === Plastic Extrusion is commonly used in industry molding technology.In order to optimize the parameters setting,it often requires repeatedly experiments and collocates with the experienced engineering technicians,so that the parameters setting can be determined accurately.Assuming there is no theoretical analyze basis in the parameter adjustment processing,it leads to inefficiencies,time-consuming and wasting production cost.Therefore, to investigate the process parameters optimization by using Taguchi method.In the process, because the conventional extrusion equipment needs of the thermocouple wire and screw combination,plug into to die in the extrusion machine to measure its temperature.The biggest problem is that the extrusion machine size needs to be changed often.To move back and forth through the auxiliary hydraulic cylinder method of forming institutions to make it easier to change size.But also because of the hydraulic cylinder moves back and forth easily pull thermocouple wire can cause damage.Therefore,using infrared thermocouple sensors instead to improve the above problems. In this thesis,an infrared temperature sensor measurement equipment,the protocol is sent to the micro-controller to do treatment.ZigBee wireless transmission by sending data to the computer.Display results in order to achieve the remote monitoring of the effects of,and use regression analysis to improve the temperature error.Taguchi method to calculate the final process parameters optimization.
