Description
【０００１】[0001]
この考案は、ワークの液処理の際、攪拌を行うバレルに関し、特に電気メッキ に好適するバレルの構造に関する。 The present invention relates to a barrel that agitates during liquid treatment of a work, and particularly to a barrel structure suitable for electroplating.
【０００２】[0002]
従来、この種のバレルは、一般には図２に示すように回転軸と直交する方向の 断面の形状が六角形であり、時には五角形となっていた。例えば、図２に示すも のは従来の電気メッキ用回転バレルである。その使用状態について述べれば、図 に示すようにバレル１の内部に形状に小さいワーク３を多数収容し、メッキ液６ に浸漬した状態でバレル１を回転させ、ワーク３を攪拌しながら陽電極板５，５ とバレル１の回転軸となる陰電極棒２との間に直流電源４による電圧の印加によ り電流を流しメッキを行う。 2. Description of the Related Art Conventionally, a barrel of this type generally has a hexagonal cross section in a direction orthogonal to the rotation axis as shown in FIG. For example, shown in FIG. 2 is a conventional rotating barrel for electroplating. As for its usage, as shown in the figure, a large number of work pieces 3 each having a small shape are housed in the barrel 1, and the barrel 1 is rotated while being immersed in the plating solution 6, and the work 3 is stirred while the positive electrode plate is stirred. Plating is performed by passing a current between the electrodes 5, 5 and the negative electrode rod 2 serving as the rotation axis of the barrel 1 by applying a voltage from the DC power supply 4.
【０００３】 このとき、メッキ液６はバレル１の表面に穿設した無数の細孔１ａからバレル １に出入りする。At this time, the plating liquid 6 enters and leaves the barrel 1 through the innumerable pores 1 a formed on the surface of the barrel 1.
【０００４】[0004]
ところで、上記の電気メッキ用バレルでは、実際に電着反応のおこる領域が、 図２に斜線で示す回転バレルの内壁面に沿ったワーク３の周辺部だけであるので 、バレル１の形状を大きくしても、メッキ時間が長くかかり、効率が悪いという 欠点があった。 By the way, in the above electroplating barrel, since the region where the electrodeposition reaction actually occurs is only the peripheral portion of the work 3 along the inner wall surface of the rotating barrel shown by the diagonal lines in FIG. However, it had a drawback that it took a long time for plating and was inefficient.
【０００５】 また、回転バレル１を回転させてもメッキ液６のバレル１内への入れ替わりが 悪く、そのためにメッキを進めていくとバレル１の内部および周辺部の金属濃度 が小さくなり、水素が発生したり局部的にＰＨが変動したりして、メッキの密着 が悪くなったり、メッキ厚不良や光沢不良等の原因になっていた。Further, even if the rotary barrel 1 is rotated, the plating liquid 6 is not easily exchanged into the barrel 1. Therefore, when the plating is advanced, the metal concentration inside and around the barrel 1 is reduced, and hydrogen is These were caused or locally changed PH, resulting in poor adhesion of the plating, defective plating thickness and defective gloss.
【０００６】[0006]
この考案のバレルは、回転バレルをその回転軸と直交する方向より見て放射方 向に突起状に形成し、その断面形状が星型となっていることを特徴とする。 The barrel of this invention is characterized in that the rotating barrel is formed in a projection shape in the radial direction when viewed from the direction orthogonal to the rotation axis, and the cross-sectional shape is star-shaped.
【０００７】[0007]
上記の形状のバレルであると、バレルの内壁内の面積が増大し、ワークの処理 液と接する面積が増えることによって、処理液によるメッキ等の反応の速度を速 くすることができる。 With the barrel having the above-described shape, the area inside the inner wall of the barrel is increased, and the area of the workpiece in contact with the treatment liquid is increased, so that the rate of reaction such as plating by the treatment liquid can be increased.
【０００８】 また、バレルが回転したときに、メッキ槽等の処理槽内のメッキ液等の処理液 の攪拌効果もあり、バレル内の処理液の入れ替わりも容易に行うことができ、バ レル内外，および槽内の処理液の酸濃度，金属濃度等の成分濃度を一定にするこ とができる。Further, when the barrel rotates, it has an effect of stirring the processing liquid such as the plating liquid in the processing tank such as the plating tank, so that the processing liquid in the barrel can be easily exchanged. , And the concentration of components such as acid concentration and metal concentration of the treatment liquid in the bath can be kept constant.
【０００９】[0009]
以下、この考案について図面を参照して説明する。図１（ａ）はこの考案の一 実施例である回転バレルの一部断面斜視図、図１（ｂ）はその電気メッキを行う 状態を示す断面図である。 The present invention will be described below with reference to the drawings. FIG. 1 (a) is a partial cross-sectional perspective view of a rotary barrel according to an embodiment of the present invention, and FIG. 1 (b) is a cross-sectional view showing a state where the electroplating is performed.
【００１０】 なお、図において図２に示す従来例と同一個所については同一参照符号を付し てその説明を省略する。In the figure, the same parts as those of the conventional example shown in FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted.
【００１１】 この実施例によれば、バレル１０の断面形状を突起状である星型にしたことに より、バレル１０の内壁内の面積を増やし（図中斜線部分）、メッキのつく部分 の面積を従来の同じ直径の六角形バレルよりも大きくすることができ、速い速度 でメッキできるという利点がある。According to this embodiment, the area of the inner wall of the barrel 10 is increased (hatched portion in the figure) by forming the barrel 10 into a star-shaped cross-section, and the area of the plated portion is increased. Can be made larger than a conventional hexagonal barrel of the same diameter, and has the advantage of being able to plate at a high speed.
【００１２】 また、同時にバレル１の回転に伴うメッキ液の攪拌も効率よく行うことができ 、そのことにより槽内および槽とバレル１内でのメッキ液の濃度も一定にするこ とができる。At the same time, it is possible to efficiently stir the plating solution accompanying the rotation of the barrel 1, which allows the concentration of the plating solution in the tank and in the tank and the barrel 1 to be constant.
【００１３】 なお、この考案は上記実施例に限定されることなく、例えばバレルの直径が大 きくなれば突起の数をさらに増やすことが容易であり、そのため突起の数を７な いし１２とすることができる。このことにより、さらにワークと処理液の接触面 積を増やすことができる。Note that the present invention is not limited to the above-described embodiment, and it is easy to further increase the number of projections, for example, when the diameter of the barrel becomes large. Therefore, the number of projections is set to 7 or 12. be able to. As a result, the contact surface area between the work and the processing liquid can be further increased.
【００１４】 また、電気メッキ以外に例えば化成処理に用いることもでき、この場合、やは り化成処理の速度を速くできる。In addition to electroplating, it can be used for chemical conversion treatment, and in this case, the rate of the chemical conversion treatment can be increased.
【００１５】 さらに、酸洗い等の電界を必要としない処理では、陰電極棒２は不要であり、 単に攪拌作用を営むものであればよい。Further, the negative electrode bar 2 is not necessary in a treatment such as pickling that does not require an electric field, and it may be any one that simply performs a stirring action.
【００１６】[0016]
以上説明したように、この考案はバレルの回転軸と直交する方向の断面形状を 、突起状で星型にしたことにより、ワークと処理液の接触面積を大きくし、反応 を速くし生産性を向上させる効果がある。 As explained above, this invention uses a projection-shaped, star-shaped cross-section in the direction orthogonal to the barrel rotation axis to increase the contact area between the workpiece and the processing liquid, accelerate the reaction, and improve productivity. Has the effect of improving.
【００１７】 また、加えて処理液の攪拌をバレルの回転と同時に行え、そのことによりバレ ルの内外の処理液の濃度を一定にできる効果があり、処理液濃度の変動に起因す る品質上のトラブルを未然に防ぐことができるという効果がある。In addition, stirring of the treatment liquid can be performed simultaneously with rotation of the barrel, which has the effect of making the concentration of the treatment liquid inside and outside the barrel constant, and is effective in terms of quality due to fluctuations in the concentration of the treatment liquid. There is an effect that the trouble of can be prevented.
