Abstract :
As a new kind of dispensing technology, jetting dispensing has a broad application prospect. The dispenser driven by two piezoelectric stacks can realize high frequency and nano dispensing to some certain viscosity of adhesive. In order to analyze the dynamic character of the needle, The model of the dispenser is established, and simulated with Matlab. Then two piezoelectric stacks´ input voltages which affect the needle´s stroke and velocity of its downward movement are analyzed. At last, in order to validate the model, measurement is carried out and compared with the result of simulation.
