Description

The present invention relates to a metal leaf manufacturing apparatus and an electrode plate mounting body.

Conventionally, as disclosed in Patent Document 1, for example, an electrolytic cell in which an electrolytic solution is stored, an electrodeposition drum (electrode) provided in the electrolytic cell so that a part of the electrolytic cell is immersed in the electrolytic cell, and the electrodeposition thereof. It has an electrode plate (anodode) that is provided so as to face the outer peripheral surface of the drum at predetermined intervals and is immersed in the electrolytic solution, and the outer periphery of the electrodeposition drum is applied by applying a voltage between the electrodeposition drum and the electrode plate. A metal foil manufacturing apparatus that electrolyzes and generates a metal foil on a surface is known.

In the metal leaf manufacturing apparatus, the electrode plate is generally attached to the front surface of a conductive (for example, titanium) substrate, and the rear surface of the substrate is supported by a support provided on the bottom surface of the electrolytic cell. (See FIGS. 3 and 4 of Patent Document 1).

By the way, the substrate of the electrode plate is usually a single plate (thin plate), and this single plate is subjected to finish processing such as R bending and cutting, and the front surface thereof is concavely curved corresponding to the outer peripheral surface of the electrodeposition drum. It is used as the mounting surface for the electrode plate.

However, in the conventional single plate substrate, the R dimension and the like may change over time due to the residual stress during the R bending process. In this case, even a slight dimensional change affects the thickness and quality of the ultra-thin metal foil, so that it is necessary to appropriately perform straightening processing and strain-removing heat treatment on the substrate, and the burden of this straightening cost is large.

Concave curved surface machining can be performed relatively easily and with high accuracy by methods other than R bending, and even when R bending is performed, dimensional changes due to residual stress can be suppressed due to the rib shape, so correction costs can be reduced. It is possible to reduce it.

Further, since the rib bodies 6 are arranged side by side, it is possible to change the number of rib bodies 6 arranged side by side according to the width dimension of the electrode plate 4, which is compared with a single plate whose width dimension cannot be changed. However, it is possible to easily realize an electrode plate mounting width that matches the width dimension of the electrode plate 4 by appropriately setting the number of rib bodies 6 arranged side by side and the parallel arrangement interval, and it is possible to improve the yield accordingly.

Therefore, in this embodiment, by configuring the substrate with a plurality of rib bodies arranged side by side, it is relatively easy to process the concave curved surface, and the influence of residual stress can be minimized to reduce the straightening cost. Etc., which is extremely practical.
