Direct-Acting Piezoelectric Jet Dispenser With Rhombic Mechanical Amplifier

In order to tackle jet motion interference between a needle and guiding part, a new piezoelectric jet dispenser based on the rhombus magnifying principle is proposed. The new jet dispenser can jet 1.4-Pa · s adhesive without preheating, which can deliver 100 adhesive dots per second. The lifespan of the nozzle and needle exceeds 20 million cycles. It will provide a new device for adhesive distribution, and the amplifying method also fits other piezoelectric applications.
