In order to realize high efficiency of dispensing for high viscosity adhesive. A non contact jetting device based on firing pin principle is successfully developed. It’s driven by a piezostack,the output displacement of which is magnified by a diamond amplification mechanism.Finite element analysis (FEA) is used to analyze the structure and the dynamic performance of the amplification mechanism.Then the fit forms between nozzle and needle is fixed after comparison and the correlative dimension is also given.MATLAB is used to solve the founded dynamic equation including piezostack,needle and amplification mechanism.The simulation results show that both the displacement and velocity of the needle meet the requirement of dispensing.In the end the experiment for jetting adhesive (viscosity of 5 Pa·s to10 Pa·s) is performed.The experimental results indicate that the jetting device can dispense the adhesive steadily.The average dispensing velocity become large with the voltage amplitude.
