ABSTRACT:
A tape feeder for advancing a carrier tape with pockets containing parts in a surface mount placement system enhances the precision and reliability with which the tape is advanced and reduces the risk of loss of parts in uncovered pockets due to vibration by provision of a sprocket wheel to advance the tape, a reciprocating shutter to retain parts in uncovered pockets, and a retaining member disposed above an edge of the tape for contacting a portion of a top surface of the tape to retain the top surface portion in a plane when the tape is engaged by the sprocket wheel. The operation of the retaining member is assisted by a guide member including front and rear guides that contact the top surface of the tape and a support block that is pressed by a support spring against the bottom surface of a portion of tape between the front and rear guides. The operation of the tape feeder is adjusted to accommodate different pitches.
