Alignment of Component Insertion Tool

A component insertion tool, like the one described in the IBM Technical Disclosure Bulletin article published in Vol. 15 No. 7, December, 1972, on pages 2241 and 2242, is initially aligned relative to its anvil and X-Y table with a special calibration card.

The special calibration card, which replaces the circuit board during alignment, includes a locating card carrying a locating plate mounted on a viewing fixture. The locating plate, viewing fixture and locating card are keyed together by card reference pins, and the combination is then mounted on the X-Y table.

The X-Y table is first aligned with a component by lining up two pins of a component with two component aligning pins on the locating plate. An X mirror gives an accurate view of the alignment from a first direction, and two Y mirrors give another accurate view at right angles to the first direction. The X-Y table is adjusted by noting its position when the pins on the component and on the locating plate match.

Once the X-Y table is aligned, it is moved to expose the anvil through the anvil viewing opening in the viewing fixture. The anvil is aligned with two anvil aligning pins by adjusting the anvil's position relative to the machine base.
