The electrode plate 4 constituting the electrode body 2 is formed of a titanium thin plate-like body, and is formed in an arc-like concave curved shape corresponding to 1/4 on the lower left and right halves of the electrodeposition drum 1.
The electrode plate 4 has a plurality of recesses 8 at arbitrary positions on the surface, and the bottoms of the recesses 8 are contact portions with the electrode plate support 5.
The electrode plate 4 is fixed to the electrode plate support body 5 by a pressing member 6 and a fixing member 7 (e.g., a screw or a bolt) in the recess 8.
The recess 8 is set to a depth at which the pressing member 6 and the head 7a of the fixing member 7 in a state in which the electrode plate 4 is fixed to the electrode plate support 5 do not protrude from the electrode plate surface, and is formed in a groove shape having a length at least equal to the width of the electrodeposition drum 1 in the width direction of the electrode plate 4.
Specifically, the recesses 8 are formed by bending the electrode plates 4, are formed in a straight line shape so as to traverse the electrode plates 4 in the electrode plate width direction perpendicular to the bending direction of the electrode plates 4, are arranged in parallel at intervals in the bending direction of the electrode plates 4, and the electrode surface portions 4a are arranged between the recesses 8.
The recess 8 is not limited to the above configuration, and may have any shape (circular or rectangular in plan view) at any position of the electrode plate 4, and may be formed by press forming without being limited to bending.
Electrode surface 4a is located above the bottom of recess 8, and is provided with gap 9 formed between it and electrode plate support 5.
That is, in the present embodiment, the electrode plate 4 has a concave-convex shape in a side view, and is formed by alternately arranging the concave portions 8 and the electrode surface portions 4a formed as convex portions with respect to the concave portions 8 in the bending direction.
Further, a support member 10 for supporting the electrode plate 4 (electrode surface portion 4a) is provided in the gap 9, and the electrode plate 4 (electrode surface portion 4a) is supported by the support member 10, so that the electrode plate 4 is prevented from being deformed by sinking and is maintained in a smoothly curved surface.
The support member 10 is formed of a strip-shaped plate made of synthetic resin (e.g., nylon, PEEK, PVC, etc.), and extends in the electrode plate width direction perpendicular to the bending direction of the electrode plate 4 (electrode surface portion 4 a).
Specifically, in the present embodiment, the support members 10 are arranged in parallel with each other with a gap therebetween in the gap 9 as shown in the figure, and are fixed to the electrode plate support body 5 by fixing members 17 such as screws or bolts.
In the present embodiment, the electrode plate 4 is slightly bent in the R-direction, and the R tolerance of the electrode plate 4 is adjusted by the height of the support member 10.
The electrode plate 4 may be formed of a single plate material, or may be formed by arranging a plurality of divided bodies 11 in parallel, and in the present embodiment, the latter structure is formed of a plurality of divided bodies 11.
The segments 11 are formed in a horizontally long plate shape that is long in the electrode plate width direction perpendicular to the bending direction of the electrode plate 4, and are arranged in parallel on the electrode plate support 5 at a predetermined interval in the bending direction of the electrode plate support 5, thereby forming the electrode plate 4.
Specifically, the divided body 11 is formed by bending two long side portions on both sides in the bending direction such that the L-shaped portions 11a face away from each other.
That is, the electrode plate 4 of the present embodiment is formed by arranging the divided bodies 11 at a predetermined interval in the electrode plate support 5 in the bending direction of the electrode plate support 5, and the concave portion 8 is formed by facing the adjacent L-shaped portions 11a of the divided bodies 11 arranged in parallel on the electrode plate support 5.
Each electrode plate 4 formed by the plurality of divided bodies 11 is configured such that a band-shaped pressing member 6 fitted in the concave portion 8 is fixed to the electrode plate support 5 by a fixing member 7, whereby the horizontal portion of the L-shaped portion 11a, which is the bottom of the concave portion 8, is pressed and fixed by the pressing member 6, and each electrode plate 4 is fixed to the electrode plate support 5.
In the present embodiment, the fixing member 7 and the pressing member 6 for fixing the electrode plate 4 to the electrode plate support 5 are respectively configured to have an insulating property.
Specifically, the fixing member 7 is a synthetic resin male screw 7, and in the present embodiment, a PEEK resin male screw 7 is used.
The pressing member 6 is also made of synthetic resin (PEEK resin) and is formed as a strip-like plate having a cross-sectional shape substantially identical to the cross-sectional shape of the recess 8, as in the fixing member 7 (male screw 7).
Specifically, the pressing member 6 is set to a height that does not protrude from the recess 8 (a height that is flush with the electrode surface portion 4a when fitted in the recess 8), a through hole 6a through which the male screw 7 is inserted is provided at a predetermined interval in the longitudinal direction, and a screw head receiving portion 6b that receives the head portion 7a of the male screw 7 is formed in an upper portion of the through hole 6 a.
That is, in the present embodiment, when the pressing member 6 is fitted into the concave portion 8 of the electrode plate 4 and the pressing member 6 is fixed by the male screw 7 to fix the electrode plate 4 to the electrode plate support 5, the head portion 7a of the male screw 7 is accommodated in the screw head accommodating portion 6b of the pressing member 6 so as to be flush with the upper surface of the pressing member 6, and further, the pressing member 6 is provided so as to be flush with the electrode surface portion 4a of the electrode plate 4, so that the surface of the electrode plate 4 does not protrude from the surface of the electrode plate 4, and the surface of the electrode plate 4 is in a smooth concave curved surface state.
As described above, in the present embodiment, the electrode plate 4 (divided body 11) is fixed to the electrode plate support body 5 by the pressing member 6 and the fixing member 7 (male screw 7), but the pressing member 6 may not be used, that is, the head portion 7a of the insulating fixing member 7 (male screw 7) may be set to an appropriate size, and the pressing member 6 may be omitted by setting the head portion 7a so as not to protrude from the surface of the electrode plate 4.
The electrode plate support 5 for fixing the electrode plate 4 configured as described above is made of titanium similarly to the electrode plate 4, and is formed in an arc-shaped concave curved shape corresponding to 1/4 on the left and right halves of the lower side of the electrodeposition drum 1.
The support member 10 is provided at a predetermined position on the surface of the electrode plate support 5, and a screw hole 18 that is screwed into the male screw 7 that fixes the electrode plate 4 (pressing member 6) at a predetermined position is provided in the electrode plate support 5 in a non-penetrating state.
Specifically, the screw holes 18 are provided on a straight line along the facing gaps of the adjacent L-shaped portions 11a of the divided bodies 11 provided in parallel on the electrode plate support 5.
The electrode body 2 of the present embodiment configured as described above is formed as follows.
The electrode plate support 5 is provided with the divided bodies 11 at predetermined intervals in parallel in the bending direction of the electrode plate support 5.
Next, the pressing member 6 is fitted into the concave portion 8 formed by the opposed L-shaped portions 11a of the adjacent divided bodies 11, and the horizontal portion of each L-shaped portion 11a is sandwiched between the pressing member 6 and the electrode plate support 5.
Next, the male screw 7 is passed through each through hole 6a provided in the pressing member 6, and the pressing member 6 is fixed to the electrode plate support 5 by screwing the male screw 7 into the screw hole 18 provided between the horizontal portions of the opposed L-shaped portions 11a of the electrode plate support 5.
Thereby, the horizontal portion of the L-shaped portion 11a of the divided body 11 is pressed and fixed by the pressing member 6, and the divided body 11 is fixed to the electrode plate support body 5 to form the electrode plate 4, thereby forming the electrode assembly 2.
In the apparatus for manufacturing a metal foil of the present embodiment including the electrode assembly 2, the fixing member 7 (male screw 7) for fixing the electrode plate 4 to the electrode plate support body 5 and the pressing member 6 have insulation properties, and therefore, local current concentration does not occur in the fixing member 7 and the pressing member 6.
Further, since the fixing member 7 and the pressing member 6 are housed in the recess 8 formed in the electrode plate 4 and are disposed in a state of being flush with the surface of the electrode plate 4, the surface of the electrode plate 4 is in a smooth surface state having substantially no unevenness, and the electrolyte 3 is allowed to smoothly flow along the surface of the electrode plate 4.
In the present embodiment, the above-described configuration is adopted, so that a metal foil having a uniform thickness can be produced without causing local current concentration on the surface of the electrode plate 4 and without hindering the flow of the electrolyte 3, and further, since the pressing member 6 is used together, the electrode plate 4 can be firmly and uniformly fixed to the electrode plate support 5 by the small number of fixing members 7.
In the present embodiment, since the screw hole 18 screwed with the male screw 7 for fixing the electrode plate 4 (the divided body 11) to the electrode plate support 5 does not penetrate the electrode plate support 5, the problem that the electrolyte 3 leaks out to the back side of the electrode plate support 5 through the screw hole 18 does not occur.
Further, since the contact portion of the electrode plate 4 that contacts the electrode plate support 5 (i.e., the horizontal portion of the L-shaped portion 11a of the divided body 11) is fixed in close contact with the electrode plate support 5 by the pressing member 6 over the entire range, there is no problem that the electrolyte 3 penetrates into the back surface side of the electrode plate 4.
As described above, since the electrolyte 3 does not come and go between the front and back surfaces of the electrode plate 4 and the electrode plate support 5, the concentration of the electrolyte 3 between the electrodeposition drum 1 and the electrode body 2 (electrode plate 4) is stable and a uniform reaction is performed, and when the electrode body 2 also has a structure of an electrolytic cell as in the present embodiment, the power feeding device can be attached to the back surface of the electrode body 2 (electrode plate support 5), and a compact device configuration can be realized.
In addition, as described above, since the metal foil manufacturing apparatus is configured such that the horizontal portion of the L-shaped portion 11a of each divided body 11 is pressed and fixed by the pressing member 6, the fixing member 7 (male screw 7) does not penetrate the electrode plate 4 (divided body 11), and thus the divided body 11 can be detached from the electrode plate support body 5 only by loosening without detaching the fixing members 7 one by one, and the maintainability is excellent.
The present invention is not limited to the present embodiment, and the specific configurations of the respective constituent elements can be appropriately designed.
