Abstract:
An electronic component mounting apparatus for sucking and holding an electronic component and mounting the electronic component into a predetermined mounting position, said apparatus comprising:an electronic component supply device for supplying a plurality of electronic components to supply a desirable one of said electronic components; a sucking nozzle for removably sucking and holding said electronic component; an attachment head for holding said sucking nozzle to rise and fall freely; a head moving device for moving said attachment head in a horizontal plane; and a viscous fluid transfer device for forming a flat viscous fluid transfer surface for transferring viscous fluid to a connecting terminal of an electronic component and for uniformly flattening a viscous fluid on a transfer unit to form a flat viscous fluid transfer surface, wherein said viscous fluid transfer device including a transfer unit having a planar pan surface for putting a viscous fluid thereon, a squeegee unit having a stirring squeegee shaped planar for stirring said viscous fluid put on said pan surface, a leveling squeegee shaped planar for uniformly flattening said viscous fluid which is stirred, and a squeegee fixing member serving to separate said stirring squeegee and said leveling squeegee from each other and to fix them in parallel, wherein both ends of said fixing member are supported pivotally and rockably above said transfer unit, a transfer unit moving mechanism for reciprocating said transfer unit such that said stirring squeegee and said leveling squeegee are relatively moved each other along the planar pan surface of said transfer unit, and a squeegee driving mechanism for rocking said squeegee unit such that said stirring squeegee approaches said pan surface on going path of said stirring squeegee and said leveling squeegee approaches said pan surface on returning path of said leveling squeegee, wherein said electronic component sucked by said electronic component supply member is moved onto said transfer unit of said viscous fluid transfer device and a terminal portion of said electronic component is immersed in said viscous fluid transfer surface by said up-down operation of said attachment head, thereby transferring said viscous fluid to said electronic component.
