Abstract

The invention relates to an apparatus (1, 101, 201) for electrochemically coating a workpiece (22), including a coating reservoir (2, 102, 202) with a charge opening (5) and a supply reservoir (3, 103, 203), wherein the two reservoirs are in communication through a passage opening (4, 104, 204). The apparatus has at least one electrode (11) and one counter electrode (14). In order to prevent contamination of a coating liquid (20, 120, 220) during an electrochemical deposition process, the apparatus can be switched between a coating position and a rest position by rotating the supply and the coating reservoirs about at least one common axis (A, A′, A″) so that the center of gravity of the volume of the coating reservoir (2, 102, 202) in the coating position is lower in relation to the center of gravity of the volume of the supply reservoir (3, 103, 203) than in the rest position. The invention further relates to a method for coating workpieces.

Dependent claims

An apparatus for electrochemically coating a workpiece, comprising

a coating reservoir (2, 102, 202) for receiving the workpiece (22) and
a supply reservoir (3, 103, 203) for coating liquid (20, 120, 220) communicating with the coating reservoir (2, 102, 202) through at least one passage opening (4, 104, 204) for the coating liquid (20, 120, 220),
a charge opening (5) for introducing the workpiece (22) into the coating reservoir (2, 102, 202), and
at least one electrode (11) for contacting the workpiece (22) and at least one counter electrode (14),
wherein the apparatus (1, 101, 201) is switchable between a coating position and a rest position by rotating the coating reservoir (2, 102, 202) and the supply reservoir (3, 103, 203) about at least one common rotation axis (A, A′, A″) in such a manner that the center of gravity of the volume of the coating reservoir (2, 102, 202) in the coating position is lower in relation to the center of gravity of the volume of the supply reservoir (3, 103, 203) than in the rest position.
