Description
Technical Field
The invention relates to an electroforming hanger for a rotatable cathode, in particular to an electroforming hanger for a rotatable planar cathode, and belongs to the field of electroforming equipment.
Background
Currently, in the electroforming industry, the uniformity of the thickness of the electroformed layer is one of the key indexes for determining whether the product has good performance. The thickness uniformity of the electroformed layer is mainly determined by the uniformity of the cathode current density distribution, the uniformity of the flow field distribution and other factors. Therefore, proper measures are adopted, so that the distribution of the cathode current density, the distribution of the flow field and the like tend to be uniform, and the method is particularly important. The reciprocating linear movement of the cathode is a stirring mode commonly used in the electrochemical deposition fields such as electroforming, electroplating and the like, and can relatively simply and effectively improve the uniformity of an electrochemical deposition layer. However, there is a limitation in that the cathode can be moved only in a single direction horizontally or vertically in this manner. On the one hand, more of the electric field or the flow field can be further homogenized in the direction of cathode movement, but the flow field and the electric field can not be homogenized on the whole surface of the workpiece, so that the electroformed layer uniform workpiece is extremely difficult to obtain. If the cathode which moves reciprocally and linearly can be rotated periodically or continuously according to the requirement in the electroforming process, the method is certainly beneficial to overcoming the limitation of the cathode which moves in a single direction, and the process effect is better. At present, in the electroforming industry, the periodic turning of the workpiece cathode is generally realized through a mode of 'unloading the hanger and the workpiece, hanging the hanger and the workpiece' and multiple manual operations, but the process and the effort are wasted.
Therefore, the patent develops the electroforming hanger capable of realizing in-situ manual steering of the workpiece cathode without repeatedly detaching and installing the hanger and the workpiece, so that the labor intensity is greatly reduced, the time is saved, and the production efficiency is improved.
