Abstract
Presence, absence, and adequacy of length of component leads are detectable by engaging each lead with a corresponding interposer and monitoring the amount of displacement of each interposer or plunger in response to the lead. Each plunger is provided with an optic fiber for guiding and directing a light beam from a transmitter to a receiver of a sensor when a lead is missing or too short. The lead engaging portion of the plunger is interchangeable to accommodate different lengths of leads and heights of cut and clinch anvils. For DIP components, each half of the inventive device receives all of the leads on one side of the component, with an individual piston for each lead. Thus, mirror image devices may be used for oppositely spaced rows of leads of a DIP, with the spacing between the mirrored halves of the device being adjustable according to the center-to-center (CTC) spacing between leads on opposite sides of the component body. Each plunger of one of the mirror halves is simultaneously engaged by a fluid common to the remaining pistons thereof for extension, as well as retraction, of the lead engaging portions.
