Abstract:  Aiming at the problems of high noise, high cost and unstable transportation in industrial production, the vibrating feeder was studied, and a centrifugal driven vibrating feeder was designed and tested. Firstly, the centrifugal motion of centrifugal motor was used as the driving source, the working principle of linear vibration feeder was studied, the mathematical model was established and the dynamic simulation of the vibration feeder was carried out. Then the experimental prototype was made, and the voltage and frequency characteristics of the linear vibration feeder prototype were tested by using a three-dimensional vibration meter to verify the established mathematical model. Finally, different types of OT-10A copper terminals were used as materials to test the conveying performance of the prototype, and it was compared with other feeder products in the market. The experimental results show that the maximum material conveying speed of the feeder is 123mm/s, and the material conveying stability is the best when the inclination angle of the supporting spring is 75°. Comparing with the products of the same model, the total weight of the feeder is reduced by 1/5 and the noise is reduced by more than 20dB. The research results can provide a certain theoretical reference for improving the industrial production feeder in the later stage.
