Abstract

In this paper, a novel linear vibrating feeder is designed that uses the centrifugal motion of an eccentric motor as the driving source. First, the working principle of the linear vibrating feeder is theoretically analyzed and the dynamic model is established. Subsequently, a dynamic simulation of the system is carried out using ANSYS software. The relationship between the displacement amplitude, vibration speed, and frequency of the linear vibrating feeder prototype is tested using a three-dimensional vibrometer, with an OT-10A copper terminal used to test the prototype. The experimental results indicate that, at a vibration frequency of 125 Hz, maximum vibration speeds of 1.23 and 1.70 mm/s are reached in the X- and Z-directions, respectively. The corresponding maximum amplitudes are 0.7 and 0.99 mm, and the material feeding speed reaches a maximum value of 123 mm/s. Compared with similar piezoelectric and electromagnetic vibrating feeders, the total weight of the prototype is reduced by a third, the noise is reduced by more than 20 dB, and the driving voltage is only 3.6 V. Hence, the performance of the linear vibrating feeder has been successfully demonstrated.
