摘要： In a variable-pitch tape feeder for feeding parts to a pick and place machine used to produce electronic circuit boards, a switch assembly is provided which controls the limits of a shutter movement and the tape advance distance dependent upon the desired pitch. The tape feeder uses a carrier tape to deliver parts to the pick and place machine. The parts are inserted into depressions at regular intervals along the length of the tape. To accommodate tapes of varying pitches, i.e., distances between parts, the feeder uses an electronic control unit to drive the tape feed mechanism and actuate a shutter. The shutter prevents small parts from escaping their respective depressions prematurely. The switch provides a stop surface which limits the rearward travel of the shutter and a flag which is detected by optical sensors to determine the position of the switch and thus the pitch desired by the operator. By limiting the rearward travel of the shutter, especially when using small-pitch parts, parts subsequent to the one positioned at the pick-up point will be prevented from escaping their respective recesses in the carrier tape. A control unit electronically advances the carrier tape the desired distance according to the position of the switch.

摘要： The present invention is a method and apparatus for the automatic loading and advancement of component feeder tape in a component feeder for use with a pick-and-place system. The feeder employs sensing technology to determine when a component tape leader is inserted into a tape guide, and subsequently auto-loads the feeder with the tape, including initiating the peeling of cover tape. Subsequently, the feeder operates to sense the presence of parts or components in the component tape pockets and to advance the component tape to a position where the first component is presented at the pick location. The feeder is also capable of detecting repeatable features in the component tape in order to automatically determine the component tape pitch.

摘要： The present invention is a method and apparatus for cutting the cover tape on a component carrier tape in order to allow component retrieval by an automated assembly system. More specifically, the cover tape is cut using a radiant energy beam that vaporizes the cover tape layer so as to partially expose the component below. The cover tape flap(s) created by the cutting operation may then be folded back so as to expose the component for retrieval at the pick-up location. Subsequent to the pick-up location, the carrier tape with the parted cover tape flap(s) attached thereto, are directed to a waste receptacle or similar disposal mechanism.
