Abstract

In semiconductor manufacture it is often necessary to perform work on both sides of a part. This device inverts flat parts which are positioned in pockets on an indexing belt 1. A paddle wheel type mechanism operates from the same drive as the indexing belt.

Inverter for Flat Parts being Indexed on a Belt

In semiconductor manufacture it is often necessary to perform work on both sides of a part. This device inverts flat parts which are positioned in pockets on an indexing belt 1. A paddle wheel type mechanism operates from the same drive as the indexing belt.

Through suitable camming, the inverter side guides 2 are indexed 45 degrees at a time during the dwell period of the belt index. As one part 3 is lifted from the belt pocket, another part 4 is simultaneously deposited into the belt pocket emptied in the previous cycle. The deposited part is in the inverted mode, bottom side up. This method of inversion uses only one moving part and does not add any time to the process cycle.
