Abstract
There is disclosed a printed circuit transferring apparatus of a surface mounter, enabling to accurately control the positions where the electronic components are to be mounted on the printed circuit board (PCB), to make it possible the work at arbitrary positions, and to further provide an easy compensation for any errors possibly occurring in mounting the electronic components. The invention provides a PCB transferring apparatus of a surface mounter for mounting various electronic components on a PCB, the apparatus comprising: a frame; an X-Y gantry provided on an upper portion of the frame, the X-Y gantry being moved along the X-Y axes; a base disposed on the frame and placed inside the X-Y gantry; a sensing unit installed on an upper portion of the base, and for sensing the PCB fed from an inlet to determine the position thereof; a PCB transferring unit for freely moving the sensed PCB on the base; and at lease one or more pickup head units installed in the X-Y gantry, and for mounting the electronic components on the PCB having been transferred by the PCB transferring unit.
