Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode for electrolysis which is capable of supplying electric power evenly over the entire area of an electrode for electrolysis which is suitable for an anode of an electrolytic cell used for producing a metal foil, particularly a copper foil. The present invention relates to a power feeding method and a power feeding structure.

[0002]

2. Description of the Related Art FIG. 11 is a schematic view for explaining an apparatus for producing an electrolytic copper foil by electroplating. In this manufacturing apparatus, a rotating cathode drum 1 formed of titanium, stainless steel, or the like is used as a cathode, and two anode plates 2 each having a shape obtained by dividing a cylinder into four in the circumferential direction are used as the anode. 2 is disposed so as to cover the lower half of the cathode drum 1 with an appropriate gap G between the cathode drum 1 and the cathode drum 1. The cathode drum 1 and the anode plate 2 are housed in an electrolytic bath (not shown), and the plating solution is allowed to flow through the gap G. Then, when a direct current is passed between the anode plate 2 and the cathode drum 1, copper is deposited on the surface of the cathode drum 1, and the deposited copper is peeled from the cathode drum 1 to obtain a copper foil.

Electric power is supplied to the anode plate 2 by connecting a bus bar 3 arranged above and an upper part of the anode plate 2 by a power supply line 4.

[0004]

However, in the above-described conventional power feeding structure, since the bus bar 3 and the upper portion of the anode plate 2 are connected, the current flows from the upper portion of the anode plate 2 to the entire anode plate 2. Will flow. Therefore, a large current locally flows in the upper part of the anode plate 2, that is, in the vicinity of the connection portion with the bus bar 3, and a small current flows in the lower part of the anode plate 2, so that the entire area of the anode plate 2 is evenly distributed. No current flows. For this reason, variations in the finish of electrolytic products such as copper foils are caused, which is one of the causes of deteriorating the yield. A so-called valve metal such as titanium has been used as a raw material due to the requirement for insolubilization of the anode plate 2. However, since the electric conductivity of these is small, the current becomes particularly uneven. Therefore, power is supplied with a large current so that a current of a predetermined magnitude flows to the end of the anode plate 2.
Overcurrent may flow in the upper part of the anode plate 2, which may cause variations in products and shorten the life of the anode plate 2. Moreover, since the flowing current is non-uniform, it is difficult to sufficiently control the current, and it may not be possible to eliminate variations in products.

Therefore, the present invention provides a method and structure for supplying electricity to an electrode for electrolysis, which allows an electric current to flow through the anode plate almost uniformly, eliminates variations in electrolytic products, and improves the yield. It is an object.

As shown in FIGS. 8 to 10, the connection band 17 is formed by lining 18 of titanium on a copper plate material. Also, as shown in FIG.
In the portions other than 11n, ..., 15n, titanium is also lined in the portions that come into contact with the electrode plate 10. That is, since the conductivity of titanium is lower than that of copper, the titanium lining brings it into a state close to insulation. Therefore, for each of the electrode pieces 11, 12, 13, 14, and 15, one bus bar 16 It means that they are electrically connected via the connection band 17.

Further, as shown in FIG.
, 15n are fixed to the back surface of the electrode plate 10 by holding means 28 such as fixing bolts so that the connection band 17 is not inadvertently deformed. In the portion held by the holding means 28, the portion in contact with the electrode plate 10 is covered with the covering member 10b.

The operation of the embodiment of the power supply structure for the electrode for electrolysis according to the present invention constructed as described above will be described below.

In order to assemble the electrode plate 10 having this power feeding structure, a predetermined number of the holding members 21 and the supporting members 21a are arranged side by side, and the reinforcing members 22 and the flanges 23 are provided on the adjacent supporting members 21a.

If the surface of the holding member 21 is made an appropriate flat surface and the back side of the substrate 10a is also made a flat surface, the holding member 21
This is preferable because the work of fixing the substrate 10a to the substrate becomes simple. The surface side of the substrate 10a is formed in a shape along an arc concentric with the center of an electrolytic drum (not shown) facing the electrode plate 10.

The substrate 10a held by the holding member 21 is covered with the covering member 10b, and the groove portion formed by the notch recess 25 in the adjacent portion of the adjacent substrates 10a,

Since the power is supplied through the electrode, an overcurrent does not flow in a part of the portion, and a current having a substantially uniform magnitude flows in the entire area of the electrode plate 10. Therefore, the products can be made uniform and the yield can be improved. In addition, the current can be controlled over the entire area of the electrode plate 10 during power feeding, and the life of the electrode plate 10 can be extended. Moreover, since a current of a required magnitude can be passed through a required portion as desired, a product that meets the required specifications can be manufactured.

Further, in order to supply electric power to the entire area of the electrode plate 10, even if the electrode plate 10 is divided into a proper number of electrode pieces 11, 12, 13, 14, 15 to form a structure between adjacent electrode pieces. It is possible to prevent the occurrence of sparks and prolong the life of the electrode plate 10.

Further, as in this embodiment, the holding member 21

Since the cover member 10b is detachably fixed to the substrate 21 with the fixing bolts 24, and the cover member 10b is detachably fixed to the substrate 10a with the set screw 26, the cover member 10b is corroded by corrosion or wear.
Can be easily replaced.

Further, in this embodiment, the holding plate 27 is fitted into the groove formed by the notch recess 25 formed at the adjacent end of the substrate 10a, and the holding member together with the covering member 27 is formed.
Since the structure is such that 10b is fixed to the substrate 10a by the set screw 26, the compatibility of the covering member 10b is improved. That is,
With this structure, a flat screw can be used as the set screw 26, and precision is not required for processing the through hole formed in the covering member 10b. Therefore, it becomes easy to manage the processing of the through holes, and the stock of the covering member 10b can be owned,
The maintenance and management of the electrode plate 10 can be facilitated and the cost can be reduced. Further, since the covering member 10b is fixed to the substrate 10a by using the holding plate 27, the close contact between them is improved, the energization efficiency is improved, and the energy saving effect is improved.

Since the conductive members are connected to each other to supply electric power, it is possible to flow a current having a substantially uniform size over the entire area of the electrode plate. Therefore, it is possible to eliminate variations in the finished products and improve the yield. Further, since it is not necessary to flow a large current so that the current sufficiently flows to the end portion of the electrode plate, the life of the electrode plate can be extended and the cost can be reduced.

Further, since the current can be controlled for each connection point, a current of a predetermined magnitude can be made to flow to a desired portion of the electrode plate as required, and the specifications required for the product can be obtained. Can be easily accommodated.
