ABSTRACT:
A robot hand for lifting an apertured panel includes a pair of tong fingers pivotally mounted upon a housing having a locating face. The tong fingers have opposed facing knuckles including a circular cylindrical wall portion adjacent the pivot and spherical cam faces adjacent the distal ends. An air cylinder operated toggle linkage moves the tong arms between a pinched together position contracting the tong finger knuckles for insertion through the aperture of the apertured panel and spread apart positions in which the circular cylindrical wall portions engage the aperture walls to locate the panel in the longitudinal and transverse directions and the spherical cam faces engage with the underside of the panel and lift the panel against the locating face of the housing.
