The work aims to design a new-type vibratory feeder driven by inertia force of piezoelectric bimorph vibrator to meet the conveying requirements on light, thin and small product in modern industry. Based on the analysis of the working principle of the vibratory feeder, the dynamic model of the piezoelectric vibrator was established. The influence of the length and mass of vibrator on the impact force and deformation were analyzed with Matlab software. A prototype of the vibratory feeder was produced and its performance was tested. The feeder was capable of conveying part when the vibration frequency was 209.5-214.5 Hz and could reach the maximum feeding rate at resonant frequency. The feeding rate increased linearly with the increase of the voltage. Comparing with the electromagnetic vibratory feeder, the current consumption of such new linear vibratory feeder is only 14% and the noise is reduced by 17 dB. Comparing with the made-in-Japan piezoelectric vibratory feeder, the transmission speed has been raised by 10%.
