Surface treatment system and workpiece-holding jig

摘要

A surface treatment system includes a surface treatment tank, a first guide rail and a second guide rail that extend at a position offset from a position over the upper opening of the surface treatment tank, and a plurality of transfer jigs that respectively hold a workpiece and are supported by the first guide rail and the second guide rail. The transfer jig includes a horizontal arm section, a first guide target section that is guided by the first guide rail, a second guide target section that is guided by the second guide rail, and a vertical arm section that is suspended from the horizontal arm section at a position between the first guide target section and the second guide target section, and holds the workpiece.

1. An electrodeposition surface treatment system comprising:
a surface treatment tank that holds a treatment solution, and has an upper opening; a first guide rail and a second guide rail that extend along a first direction that is parallel to a longitudinal direction of the surface treatment tank at a position offset from a position over the upper opening of the surface treatment tank; and a plurality of transfer jigs that respectively hold a workpiece that is immersed in the treatment solution contained in the surface treatment tank, and are supported by the first guide rail and the second guide rail, a feed rail that extends along the first direction between the first guide rail and the second guide rail at a position offset from a position over the upper opening of the surface treatment tank and supplies current to the plurality of transfer jigs, each of the plurality of transfer jigs including: a horizontal arm section that extends along a second direction that intersects the first direction; a first guide target section that is supported on one end of the horizontal arm section, and is guided by the first guide rail; a second guide target section that is supported on another end of the horizontal arm section, and is guided by the second guide rail; and a vertical arm section that is suspended from the horizontal arm section at a position between the first guide target section and the second guide target section, and holds the workpiece, and each of the plurality of transfer jigs including a feed target section that is supported by the horizontal arm section at a position between the first guide target section and the vertical arm section, and comes in contact with the feed rail.
