塑膠擠製成型是目前工業上常使用的成型技術,為了進行最佳化參數之設定,常需要進行許多次的實驗,並配合工程技師的多年經驗判斷,才能準確設定參數。假設在參數調整的過程中,無理論分析模擬之依據,易造成無效率、費時,且浪費生產成本,因此以田口法(Taguchi Method)探討製程參數組合的最佳化。在製程中,因為傳統式的擠製設備需要將熱電偶線與螺絲結合,栓入至擠製機模頭中,量測其溫度;而最大問題在於擠製機模頭常需變更尺寸,以藉由油壓缸前後移動輔助成型機構之方法,使變更尺寸更容易,但也因油壓缸前後移動會造成熱電偶線容易拉扯而損壞,故使用紅外線感測器取代原有之熱電偶,改善上述之問題。 本論文以紅外線感測器量測設備溫度,經通訊協定傳送至微控制器作處理後,藉由無線傳輸ZigBee,將資料傳送至電腦端,以達到遠端監測之目的,並利用迴歸分析改善了溫度誤差,最後以田口法求出製程參數組合的最佳化。
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.
