Abstract

A singulation apparatus and method including: at least one chuck station to which a workpiece is securable, the at least one chuck station being configured to move along a feed direction; a bridge extending above the at least one chuck station, the bridge having a first side and a second side opposite the first side; a first cutting device with members mounted to the bridge and being independently movable along the first side, transversely to the feed direction; and a second cutting device with members mounted to the bridge and being independently movable along the second side, transversely to the feed direction, the first and second cutting devices being configured and arranged for cutting the workpiece.

First claim

The invention claimed is:

1. A singulation apparatus, comprising:
at least one chuck station to which one or more workpieces are securable, the at least one chuck station being configured to move along a feed direction;
a bridge extending above the at least one chuck station, the bridge having a first side and a second side opposite the first side;
a first cutting device mounted to the bridge and being independently movable along the first side, transversely to the feed direction, wherein the first cutting device comprises a first cutting member and second cutting member movably mounted on the first side of the bridge; and
a second cutting device mounted to the bridge and being independently movable along the second side, transversely to the feed direction, wherein the second cutting device comprises a third cutting member and a fourth cutting member movably mounted on the second side of the bridge,
each of the first, second, third, and fourth cutting members being configured and arranged to be independently movable with respect to one another for cutting the one or more workpieces.

2. The singulation apparatus according to claim 1 , wherein the bridge comprises a first bridge member to which the first cutting device is mounted, and a second bridge member to which the second cutting device is mounted, the second bridge member being separated from the first bridge member.

3. The singulation apparatus according to claim 1 , wherein each of the first and second cutting devices comprises a plurality of cutting members.

4. The singulation apparatus according to claim 3 , wherein the plurality of cutting members of each of the first and second cutting devices are arranged in one or more pairs, wherein each pair of cutting members comprises blades, wherein the blades of the pair of cutting members or the blades of each pair of cutting members face each other to cut the workpiece along the feed direction.

5. The singulation apparatus according to claim 4 , wherein the total number of pairs of cutting members of the first and second cutting devices is equal to the number of chuck stations.
