Abstract:
1. A vibration feeding apparatus comprising: a receptacle for holding and conveying components; first and second linear motors coupled to the receptacle, the first and second linear motors being spaced from each other and comprising respective coils that are aligned parallel to each other, wherein the first and second linear motors are operative to be driven at a first operation mode whereby to impart rotary vibration to the receptacle, and at a second operation mode whereby to impart linear vibration to the receptacle; a vibratory top plate for supporting the receptacle and a vibration isolation base, wherein the linear motors are located between the vibration top plate and the vibration isolation base; at least one pair of structural springs connecting the vibrator top plate to the vibration isolation base, wherein the structural springs guide the rotary and/or linear vibration of the receptacle; and an electromagnetic clutch coupled to each structural spring, the electromagnetic clutch being configured to engage the structural spring to the vibration top plate when it is actuated.
