Abstract: Aiming at piezoelectric transducer electrically low acoustic conversion efficiency, liable to cause heat, damage, piezoelectric transducer and the ultrasonic generator was difficult to match in traditional assembly method and in order to realize the automatic assembling of piezoelectric transducer and improve assembly precision, study on the assembly method, four pillar of piezoelectric transducer assembly machine was developed. The basic parts of the assembly machine was discussed. The mechanical structure of mechanical was investigated through simulation analysis, the motor′s control method and process of control system was introduced. New piezoelectric transducer was assembled, and the performance parameters of the piezoelectric transducer was measured. The research results indicate that it is high efficiency, and this assembly method can improve the quality, stability and reliability of piezoelectric transducer. The quality of piezoelectric transducers is increase, and it tends to be stable after 7 days.
