Theoretical Analysis & Experimental Research on Piezoelectric Vibration Feeder by Vertical Driving

Abstract:

The Present Electromagnetic/piezoelectric Vibration Feeder can’t be Compressed along the Height Direction, and the Application is Limited because of the Small Assembly Area. Therefore, a New Structure Piezoelectric Vibration Feeder was Brought up in this Paper, which had Cirque Piezoelectric Vibrator for Vertical Driving, and the Dimension of the Height can be Reduced to below 30% of the Present Feeder. Based on the Structure Character of the Feeder, the Vibration Model was Built up, and the Calculation Method of the System Resonance Frequency, the Stiffness Matching Relationship of the Supporting Spring and Piezoelectric Vibrator were Confirmed through Theoretical Analysis and Experimental Research. Experiments were Done to the Prototypes, which Turned out that, under the Sine Voltage of 220V, the Feeder could have 0.5kg Stuff for Experiment (samples), which were Columns with Dimension Φ3mm×5mm, and the Feeding Speed can be up to 145mm/s. the Measured Resonance Frequency was 187Hz, which had High Coherency with Theoretical Calculation Value.
