Abstract:
A curved surface screen-printing apparatus, comprising:a jig table having a curved surface on which a printing board bent to have an arcuate section is placed;curved surface guides having an equal radius of curvature being respectively provided on side portions of said jig table in such a manner as to be concentric with said jig table;a squeegee head adapted to move in a direction perpendicular to a longitudinal direction in which each of said curved surface guides extends and crossing over said jig table;a screen plate mounting frame provided above said jig table; andat least two pairs of metal belts, each pair of metal belts connecting a corresponding one of said guides to said screen plate mounting frame,wherein said belts of each pair are arranged to intersect each other,wherein an end of each of said belts is fixed to a side end portion of a corresponding one of said curved surface guides as viewed from a side thereof, whereas another end thereof is fixed to a respective corner portion of said screen plate mounting frame, andwherein said squeegee head is further movable in a reciprocating motion which causes said screen plate mounting frame to perform a rocking motion along the curved surface of said jig table.
