Research of Vibratory Feeder Activated by the Bimorph Vibrator

To meet the requirement of smooth convey for light, thin and small product in modern industrial area, a new type of vibratory feeder activated by the bimorph vibrator was proposed in this paper. The dynamic model of bimorph vibrator was established by analyzing the working principle. A prototype of the piezoelectric vibratory feeder was produced and tested. The relationship among voltage, amplitude, frequency and feeding speed was obtained from the experiments. The experimental results show that the proposed vibratory feeder had good performance at resonance. The amplitude and feeding rate increase linearly with voltage. The proposed vibratory feeder will have wide prospects in the automatic assembly line.
