Abstract
Abstract An apparatus for selecting predesignated transistor components from a plurality of loading stacks, transporting them to a pickup position by a shuttle mechanism, transferring them to an insertion head collet member, inserting them into a circuit board and clinching the leads thereof. The apparatus includes an X-Y axis positioning mechanism and a rotary holder for the circuit board that allows the components to be inserted into the circuit board at 0°, 90°, 180° and 270° orientations.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
An apparatus for sequentially selecting a predetermined electrical component, transferring it to a position whereupon it is inserted into a circuit board and clinching said component, said apparatus comprising a magazine means, transport means for selecting components from said magazine means and transporting them to a transfer position, component insertion means for taking components from said transport means at said transfer position and for inserting them into pre-existing holes in a circuit board, said component insertion means including a swing arm means, having a collet means on the end thereof, for swinging out and picking up components from said transfer means by engaging them with its collet means and bringing them back to an in-line insertion position, means for holding said circuit board in varied positions and orientations to said insertion means and for repositioning said circuit board between insertion cycles and means for cutting and clinching said component leads located beneath said circuit board.
Claim 2
Independent Claim
155 words
An apparatus for sequentially selecting a predetermined electrical component, transferring it to a position whereupon it is inserted into a circuit board and clinching said component, said apparatus comprising a magazine means, transport means for selecting components from said magazine means and transporting them to a transfer position, component insertion means for taking components from said transport means at said transfer position and for inserting them into pre-existing holes in a circuit board, said component insertion means including a swing arm means, having a collet means on the end thereof, for swinging out and picking up components from said transfer means by engaging them with its collet means and bringing them back to an in-line insertion position, means for holding said circuit board in varied positions and orientations to said insertion means and for repositioning said circuit board between insertion cycles and means for cutting and clinching said component leads located beneath said circuit board.
Claim 3
Dependent Claim
42 words
