Abstract
An indexing conveyor transfers circuit boards between spaced insertion stations at which alignment pins clamp the circuit boards to fixed reference positions. A component insertion head and a clinch mechanism are horizontally driven about two axes to a programmed insertion position, and then are vertically driven to perform an insertion operation. After each insertion station inserts a plurality of different components at different programmed positions, the alignment pins are withdrawn and the conveyor is indexed. The index conveyor and all insertion stations are controlled by a time-shared computer which stores, for each insertion station, a separate program comprising sets of numerical control movement commands.
