1. An apparatus for dipping plating, comprising:
- a dipping plating tank;
a pair of spaced, elongated rails supported above said plating tank;
a support carriage including a carrier base supported on said rails for movement therealong and a rack base suspended from and supported on said carrier base for upward and downward movement with respect to said carrier base in directions toward and away from said plating tank, said rack base having first means for holding the objects to be plated;
pressure means disposed above said plating tank for effecting said movement of said rack base downwardly and upwardly toward and away from said plating tank, said pressure means including a fluid pressure operated piston and cylinder assembly having a downwardly extending piston rod, a pressure frame connected to the lower end of said piston rod, at least one downwardly extending pressure bar secured to said pressure frame and engageable with said rack base as said pressure frame is moved downwardly for pressing said rack base downwardly relative to said carrier base, and at least one suspension bar secured to and extending downwardly from said pressure frame; and
second holding means secured to the lower end of said suspension bar so as to be adjacent said objects to be plated on said rack base when said pressure bar is engaging said rack base for resisting disengagement of said objects from said first holding means on said rack base.

Abstract
An apparatus for dipping plating objects such as IC lead frame of a rectangular shape obtained by press forming and etching thin metal pieces, wherein a plural number of said rectangular sheets aligned and supported on the freely descending and returning rack base of the support carriage of the objects to be plated are concurrently subjected to dipping plating by determining the position of the said plural number of rectangular sheets to be plated for lowering into the plating tanks, and abutting the upper surface of the objects to be plated with the holding means thereby subjecting a plural number of objects to be plated.

9. An apparatus for dipping plating comprising:
-
a plurality of dipping plating tanks, each said tank corresponding to a plating processing step; a pair of spaced, elongated rails supported above said plating tanks; a plurality of support carriages, each said support carriage having a carrier base supported on said pair of rails for movement therealong and a rack base suspended from and supported on said carrier base for upward and downward movement with respect to said carrier base in directions toward and away from a respective said plating tank, said rack base having first means for holding the objects to be plated; pressure means disposed above said plating tanks for moving said rack bases downwardly and upwardly toward and away from said plating tanks, said pressure means including at least one fluid pressure operated piston and cylinder assembly having a downwardly extending piston rod, a pressure frame attached to the lower end of said piston rod, a plurality of downwardly extending pressure rods secured to said pressure frame and engageable with respective said rack bases as said pressure frame is moved downwardly for pressing said rack bases downwardly with respect to said carrier base, and a plurality of suspension bars secured to and extending downwardly from said pressure frame; and a plurality of second holding means secured to the lower ends of respective said suspension bars above respective said rack bases so as to be adjacent said objects to be plated on said rack bases when said pressure rod is engaging said rack base for resisting disengagement of said objects from said first holding means on said rack bases. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
