ABSTRACT:
Three sets of pincer units depend from a flat palm, each pincer unit having a pinching gap at its distal end for engaging a loaded circuit board by its edges and holding it in a spaced-apart relationship with the palm. Each pincer unit includes a finger having a flange at its distal end and a thumb slideably mounted on the finger so as to define a variable pinching gap. The fingers are mounted for prehensiling movement away from one another for bracketing a board to be picked up and toward one another so that the board to be picked up may be squeezed between them.
The invention includes a method for picking up a loaded circuit board which involves bracketing a board to be picked up between a set of pincer units, squeezing the board by moving the pincer units toward one another against opposing edges of the board while simultaneously pinching each edge engaged with the pincer units.
