ABSTRACT:
A drive mechanism for raising and lowering the placement head of an electrical component assembly machine, the mechanism having a servo motor driving a lead nut engaging a lead screw which carries the placement head. The servo motor, in response to the machine control, rotates the lead nut to lower the placement head the desired distance from the board for proper placement in the board. A pair of rollers contact upper flat surfaces on the lead screw to prevent axial rotation of the lead screw.
