金屬箔製造裝置及電極板安裝體Metal foil manufacturing device and electrode plate mounting body

本發明，是關於金屬箔製造裝置及電極板安裝體。The present invention relates to a metal foil manufacturing apparatus and an electrode plate mounting body.

以往，例如專利文獻1所揭示般，已知有金屬箔製造裝置，其具有：儲存有電解液的電解槽、使一部分浸泡在電解液地設置在電解槽內的電鍍筒(陰極)、與該電鍍筒的外周面以既定間隔來相對向地設置之浸泡於電解液的電極板(陽極)，藉由對電鍍筒與電極板之間施加電壓而在電鍍筒的外周面電鍍生成金屬箔。
而且，在上述金屬箔製造裝置，一般為以下構造：電極板，是安裝在導電性(例如鈦製)之基體的前面，將該基體的後面以設置在電解槽之底面的支撐體來支撐(參照專利文獻1的圖3及圖4)。
但是，電極板的基體，通常為單片板(薄板)，對該單片板施以R撓曲加工及切削等之收尾加工，使其前面對應電鍍筒的外周面而成為凹彎曲的電極板安裝面。
但是，在以往之單片板的基體，有著因R撓曲加工時的殘留應力而使R尺寸等發生經時變化的情況。在該情況，由於些許的尺寸變化亦會對極薄的金屬箔的厚度或品質造成影響，故產生了對基體適當進行矯正加工或去歪曲熱處理的必要，而該矯正成本的負擔為大。

However, in the base body of the conventional single-plate, there is a case where the R dimension or the like changes with time due to residual stress at the time of R deflection processing. In this case, since a slight dimensional change also affects the thickness or quality of the extremely thin metal foil, it is necessary to appropriately perform the correcting process or the buckling heat treatment on the substrate, and the burden of the correction cost is large.

且，由於構成為並排設置肋體6，故可因應電極板4的寬度尺寸來變更肋體6的並排設置數，與無法變更寬度尺寸之以往的單片板之基體相比之下，能將肋體6的並排設置數及並排設置間隔予以適當設定而可簡單地實現電極板4之寬度尺寸一致的電極板安裝寬度，這可提升產量(使電極板4的寬度與電極板安裝面的電極板安裝寬度盡可能地接近的話可有效率地製造最寬廣的金屬箔)。

[實施例]
基於圖式來說明本發明之具體的實施例。
本實施例，是金屬箔製造裝置，具有：儲存有電解液1的電解槽2、設在該電解槽2的電鍍筒3、使表面與前述電鍍筒3的外周面相對向而設置在前述電解槽2內的電極板4，前述電極板4的表面是設定成沿著相對向之前述電鍍筒3之外周面的凹彎曲面，該電極板4是安裝在設在前述電解槽2內的電極板安裝體5，該電極板安裝體5，是使前面與前述電極板4的凹彎曲面同樣地凹彎曲且將複數個肋體6透過既定間隔來並排設置而構成，該各肋體6的前面是設定成安裝前述電極板4的電極板安裝面5’。
亦即，本實施例，是如圖1所示般，具有：儲存有電解液1(硫酸銅液)的電解槽2、使一部分浸泡在電解液1地設置在電解槽2內的電鍍筒3(陰極)、與該電鍍筒3的外周面以既定間隔來相對向地設置之浸泡在電解液1的電極板4(陽極)，藉由對電鍍筒3與電極板4之間施加電壓而在電鍍筒外周面電鍍生成(鍍敷)金屬箔，而使電極板安裝體5成為既定的形狀。且，在本實施例，電極板4是與電鍍筒3之浸泡部分的左側及右側分別相對向地在左右設置一對。
圖中，符號8，是電鍍筒3的旋轉軸，9是將安裝有電極板4的電極板安裝體5予以支撐的支撐體，10是將電解液1供給至電鍍筒3與電極板4之對向間隙的液供給部。
本實施例，是如圖2所示般，以其左右側面彼此相對向的方式並排設置複數個肋體6，各肋體6的前面是構成：與電鍍筒之外周面的彎曲程度(電極板4之表面的彎曲程度)一致之凹彎曲形狀的電極板安裝面5’。於該電極板安裝面5’以螺栓等來固定電極板4。
電極板4是與電極板安裝面5’的凹彎曲面形狀相同地凹彎曲的薄板狀體。該電極板4是單片板狀亦可，為將分割體並排設置而形成的分割形狀亦可。圖中，符號11為螺絲孔。
肋體6是具有左右方向寬度之2倍以上的前後方向厚度(在圖式中，肋體6的左右方向寬度是為了說明而誇張地表示)。如此地成為將肋體6予以複數並排設置的構造，藉此可不增加體積(成本)便提升剛性。
且，肋體6是構成為往與電極板4的表面(凹彎曲面)正交的方向突出(從電極板4的內面垂直地突出)，該各肋體6是並排設置成互相平行。
在本實施例中，設有將肋體6的一端部彼此予以連結的通電用連結體7。通電用連結體7是剖面L字狀的板狀體，其下表面是藉由溶接而與肋體6的上表面連結。
肋體6的一端部，是設定成越靠通電用連結體7側則前後方向厚度越逐漸變厚的形狀。電極板安裝體5，是透過通電用連結體7來與電極(圖示省略)連接，但使肋體6成為越靠通電用連結體7側越厚的形狀，藉此可確保兩者之通電用的接觸面積較廣。

例如在其他例中，是構成為可對本實施例之最外側的肋體6進一步分別裝卸自如地將一或複數個肋體6予以並排設置。該情況，可因應使用者之電極板4之寬度等來適當調整電極板安裝面的寬度(電極板安裝寬度)。且，在增加肋體6之並排設置數的情況，亦適當增加通電用連結體7。
且，在其他例中，雖如圖3所示般以雙頭螺栓13與螺帽14來連接相鄰的肋體6彼此，藉此構成為可簡單地裝卸，但亦可用焊接等其他的手段來連結成可裝卸。圖中，符號15是螺栓插通孔。又，將螺栓插通孔15作為螺絲孔而構成為使雙頭螺栓13直接螺合亦可。該情況時，裝卸變得更容易，例如使雙頭螺栓13的一端側為右旋螺紋、使另一端側為左旋螺紋(逆旋螺紋)的話亦可調整間隔。
本實施例是如上述般構成，而以複數個肋體6來構成電極板安裝體5，藉此比起將單片板的寬大面予以高精度加工的情況，即使各肋體6的凹彎曲面加工是R撓曲加工以外的方法亦可比較容易以高精度地來進行，且，即使是R撓曲加工的情況，亦可由該肋形狀來抑制殘留應力的尺寸變化，而可刪減矯正成本。
且，由於構成為並排設置肋體6，故可因應電極板4的寬度尺寸來變更肋體6的並排設置數，與無法變更寬度尺寸的單片板相比之下，能將肋體6的並排設置數及並排設置間隔予以適當設定而可簡單地實現與電極板4之寬度尺寸一致的電極板安裝寬度，這可提升產量。
藉此，本實施例，是將複數個肋體予以並排設置來構成基體，藉此使凹彎曲面加工變得比較容易且盡可能減少殘留應力的影響而可刪減矯正成本等，是極為實用者。Embodiments suitable for the present invention will be briefly described based on the drawings showing the effects of the present invention.
When the electrode plate mounting body 5 is constituted by a plurality of ribs 6, the processing of the concave curved surface of each rib 6 is a method other than the R bending process, compared with the case where the wide surface of the single plate is processed with high precision. It is also easier to carry out with high precision. Further, even in the case of the R bending process, the rigidity can be increased by the shape of the rib (cross section), and the dimensional change due to the residual stress can be suppressed, and the correction cost can be reduced.
Further, since the ribs 6 are arranged side by side, the number of the ribs 6 arranged side by side can be changed in accordance with the width dimension of the electrode plate 4, and compared with the base of the conventional single-plate which cannot change the width dimension, The side-by-side arrangement number of the ribs 6 and the side-by-side arrangement intervals are appropriately set to simply realize the electrode plate mounting width in which the width dimension of the electrode plate 4 is uniform, which can increase the yield (the electrode of the electrode plate 4 and the electrode plate mounting surface) The widest metal foil can be efficiently produced if the panel mounting width is as close as possible.

For example, in another example, one or a plurality of ribs 6 may be arranged side by side in a detachable manner to the outermost ribs 6 of the present embodiment. In this case, the width (electrode plate mounting width) of the electrode plate mounting surface can be appropriately adjusted in accordance with the width of the electrode plate 4 of the user or the like. Further, when the number of the ribs 6 arranged side by side is increased, the current-carrying connecting body 7 is appropriately added.
Further, in another example, as shown in FIG. 3, the adjacent ribs 6 are connected by the stud bolt 13 and the nut 14, so that the ribs 6 can be easily attached and detached, but other means such as welding can be used. Come link to be loaded and unloaded. In the figure, reference numeral 15 is a bolt insertion hole. Further, the bolt insertion hole 15 may be configured as a screw hole so that the stud bolt 13 may be directly screwed. In this case, the attachment and detachment becomes easier. For example, if one end side of the stud bolt 13 is a right-handed screw thread and the other end side is a left-handed screw thread (reverse thread), the interval can be adjusted.
In the present embodiment, as described above, the electrode plate mounting body 5 is constituted by a plurality of ribs 6, whereby the concave surface of each of the ribs 6 is bent compared to the case where the wide surface of the single plate is processed with high precision. The surface processing is a method other than the R deflection processing, and it is also relatively easy to perform with high precision. Even in the case of the R deflection processing, the rib shape can be used to suppress the dimensional change of the residual stress, and the correction can be eliminated. cost.
Further, since the ribs 6 are arranged side by side, the number of the ribs 6 arranged side by side can be changed in accordance with the width dimension of the electrode plate 4, and the ribs 6 can be made in comparison with the single plate in which the width dimension cannot be changed. The side-by-side arrangement number and the side-by-side arrangement interval are appropriately set to easily realize the electrode plate mounting width in accordance with the width dimension of the electrode plate 4, which can increase the yield.
Therefore, in the present embodiment, a plurality of ribs are arranged side by side to form a base body, whereby the concave curved surface processing is relatively easy, and the influence of residual stress is minimized, and the correction cost can be reduced, which is extremely practical. By.
