Patent ID: 8733587

Claim:
An automatic part feeder, comprising: a base comprising a first end surface, an opposite second end surface, one first accommodating hole and a plurality of second accommodating holes, the first and second accommodating holes being separated from each other and each being exposed at the first end surface; a plurality of part delivering devices accommodated in the respective second accommodating holes, each of the part delivering devices comprising a ring-shaped receiving room opening toward the first end surface, a first driving motor having a first rotatable shaft, and an ejector pole having one end extending through the ring-shaped receiving room and another end threadedly engaged with the first rotatable shaft, the ring-shaped receiving room configured for receiving a plurality of parts, the ejector pole being movable outwardly by means of rotation of the first rotatable shaft, thereby ejecting the parts out of the ring-shaped receiving room; a rotatable disk driving device accommodated in the first accommodating hole, the rotatable disk driving device having a second driving motor having a second rotatable shaft; and a rotatable disk covering the first end surface, the rotatable disk comprising a plurality of first receiving holes and a plurality of second receiving holes, the second rotatable shaft engaged with the rotatable disk and configured for driving the rotatable disk to rotate between a first position where the first receiving holes are aligned with the respective ring-shaped receiving rooms thus allowing the parts to be ejected from the ring-shaped receiving rooms, and at a second position where the second receiving holes are aligned with the respective ring-shaped receiving rooms thus allowing the parts to be ejected from the ring-shaped receiving rooms.
