There is disclosed an apparatus for adjusting the origins of module heads of a surface mounting apparatus for a dual gantry, the adjusting apparatus, and method therefor. The invention includes the X-Y gantry consisting of first and second X-axis linear motors and first and second Y-axis linear motors, and having X-Y plane on which first and second reference points and a mark indicating the origin (MIO) are set, first and second module heads installed at the first a nd second X-axis linear motors, first and second vision units installed in vicinity of the first and second module heads, respectively, and for sensing the first and second reference points and the MIO and generating and outputting coordinates of the sensed first and second reference points and the MIO, and a controller for driving the first and second X-axis linear motors and the first and second Y-axis linear motors to move the first and second vision units to the first and second reference points and the MIO, receiving the coordinates output from the first and second vision units to compute offset values relating to the first and second module heads, and, if there are the offset values, setting the origins of the first and second module heads by correcting the offset values. Thus, the repeated precision of the adjustment of the origins can be improved, also, the apparatus for adjusting the origins of the first and second module heads are easily incorporated into the surface mounting apparatus for the dual gantry.
