Modern automatic assembly puts forward higher requirements for the stability and accuracy of material conveying. In order to meet industrial needs, a piezoelectric vibration that uses a rectangular piezoelectric vibrator as an excitation source and works in a vertical drive mode was designed. Feeder. By simplifying the double⁃cantilever piezoelectric vibrating feeder and establishing its dynamic model, the expressions of natural frequency and device amplitude were derived, and some factors affecting natural frequency and amplitude were analyzed. Use ANSYS Workbench software to analyze the dynamics of the device. The natural frequency of the system was 118.85 Hz, and the harmonic response analysis of the device was performed. The results show that when the driving voltage is 200 V, the system driving frequency is between 116.00～122.00 Hz, and the double cantilever piezoelectric vibration gives The feeder has the ability to transport materials, the vibration amplitude is the largest at the point closest to the resonance point (118.00 Hz), and the transport efficiency is the highest, which can meet the requirements of industrial production.
