中文摘要 | 壓電式噴墨列印頭之一噴孔噴墨機構,其主要係利用積層式壓電陶瓷材料作為致動器,推動振動板上的島板,該島板係由彈性膜片材料支撐其邊緣,島板受壓電致動器之推動,可改變壓力艙內之體積容量,而使墨水之流速及壓力升高,進而推擠墨水從噴嘴孔噴出。本文以有限元素方法及田口氏最佳設計方法得到振動板的最佳尺寸,並且依照此最佳尺寸實作一噴墨頭。 |
英文摘要 | The one nozzle of a piezoelectric ink-jet print head sprays the ink-jet mechanism by making use of multilayered piezoelectric ceramic materials used primarily for an actuator which pushes an island plate, an elastic membrane which props up its edge. When the island plate is subjected to the push of the piezoelectric actuator, the volume capacity of the pressure chamber can be changed and the velocity and pressure of the ink made to increase, thereby squeezing ink from the nozzle injection to the paper. In this article, the design was accomplished by analysis with finite element modeling and the Taguchi optimization technique, after which the optimization dimension of the vibration plate was obstained. Furthermore, according to such an optimization dimension, an ink-jet head was made. |
