    摘要: A robot for mounting a chip on a printed circuit board includes a body movable along a forward/backward axis, and a chip-carrying head unit movable longitudinally along the body transversely of the forward/backward axis. Due to manufacturing tolerances the longitudinal axis of the body is slightly inclined relative to a leftward/rightward axis oriented perpendicular to the forward/backward axis by an error angle which can be measured. The head unit is intended to be positioned at target coordinates on the forward/backward axis and the leftward/rightward axis, respectively. An operation unit determines, as a function of the error angle, a position of the head unit relative to the body, and a position of the body relative to the forward/backward axis, which would place the head unit at the target coordinates. A controller connected to the operation unit actuates a drive mechanism for moving the head unit and body to those respective positions.
