Curved surface screen-printing apparatus |
摘要 |
A curved surface screen-printing apparatus adapted to screen-print a to-be-printed object having a large radius of curvature. Concentric curved-surface guides having an equal radius of curvature are respectively provided on both side portions of a jig table on which a printing board to be bent and used as the to-be-printed object is placed. A squeegee head crossing over the jig table, and a screen plate mounting frame are provided in the apparatus. A pair of steel belts are used to connect a corresponding one of the guides to the frame. The belts of each pair are made to intersect each other. An end of each of the belts is fixed to a side end portion of a corresponding one of the curved surface guides as viewed from a side thereof. The other end thereof is fixed to a corner portion of the screen plate mounting frame. A reciprocating motion of the squeegee head causes the screen plate mounting frame to perform a rocking motion along the curved surface of the jig table. Thus, an optimum gap between the screen plate and the to-be-printed object is maintained at all times in such a manner as to be uniform therebetween.
