Abstract

A feeding apparatus for supplying electronic devices for pick-up comprises a guide track for guiding and feeding a plurality of electronic devices and a separator operative to receive electronic devices from the guide track for the electronic devices to be picked up from the separator. A protrusion is located on either of the guide track or the separator, and a cavity is located on the other of the guide track or the separator for receiving the protrusion. The protrusion and the cavity cooperate to form a substantially continuous surface for transferring the electronic devices to the separator.

First claim

The invention claimed is:

1. A feeding apparatus for supplying electronic devices for pick-up, the feeding apparatus comprising:
a guide track for guiding and feeding a plurality of electronic devices;
a separator operative to receive electronic devices from the guide track for the electronic devices to be picked up from the separator;
a protrusion located on at least one of the guide track and the separator, the protrusion comprising an abutment surface extending from a top portion of a side wall of the at least one of the guide track and the separator; and
a cavity located on the other of the guide track or the separator, the cavity comprising an indented surface recessed into a top portion of a side wall of the guide track or the separator,
wherein the cavity is configured to receive the protrusion, such that the abutment surface and the indented surface cooperate to form a substantially continuous surface for transferring the electronic devices to the separator; and
wherein a plane perpendicular to a direction of travel of the electronic devices intersects at the cavity portions of both the abutment surface and the indented surface comprised in the substantially continuous surface.

2. The feeding apparatus as claimed in claim 1 , wherein the separator is configured to move reciprocally between a first position next to the guide track to receive the electronic devices and a second position spaced from the guide track for the electronic devices to be picked up,
wherein the substantially continuous surface is formed at the first position of the separator.

3. The feeding apparatus as claimed in claim 2 , further comprising a gap between the protrusion and the cavity at the first position of the separator.

4. The feeding apparatus as claimed in claim 1 , wherein the protrusion is located at an end portion of the separator, and the cavity is located at an end portion of the guide track.

5. The feeding apparatus as claimed in claim 1 , wherein the protrusion is located at an end portion of the guide track, and the cavity is located at an end portion of the separator.

6. The feeding apparatus as claimed in claim 1 , wherein the protrusion and cavity are V-shaped from a plan view of the feeding apparatus.

7. The feeding apparatus as claimed in claim 6 , further comprising a chamfer located at a tip end of the protrusion.

8. The feeding apparatus as claimed in claim 1 , wherein the protrusion and cavity are W-shaped from a plan view of the feeding apparatus.

9. The feeding apparatus as claimed in claim 8 , further comprising chamfers located at respective tip ends of the protrusion.

10. A feeding apparatus for supplying electronic devices for pick-up, the feeding apparatus comprising:
a guide track for guiding and feeding a plurality of electronic devices;
a separator operative to receive electronic devices from the guide track for the electronic devices to be picked up from the separator;
a protrusion located on at least one of the guide track and the separator;
a cavity located on the other of the guide track and the separator, the cavity configured to receive the protrusion such that the protrusion and the cavity cooperate to form a substantially continuous surface for transferring the electronic devices to the separator, the substantially continuous surface is formed at the first position of the separator,
wherein the separator is configured for reciprocating motion between a first position next to the guide track to receive the electronic devices and a second position spaced from the guide track for the electronic devices to be picked up; and
further comprising a gap between the protrusion and the cavity at the first position of the separator.
