Simply cylindrical or waterfowl beak-shaped blow-off nozzles were used.

ずしも満足するものではなかつた。 However, when the present inventors conducted a detailed study on continuous alloy electroplating equipment in general, they found that
Uniform distribution of the plating liquid during plating, that is, when flowing the plating liquid in countercurrent or forward flow, ensuring uniform plating quality by making the flow velocity distribution of the plating liquid as uniform as possible on the surface to be plated. I found out that it is necessary to do so. When we reexamined conventional plating liquid blowing devices from this point of view, we found that they were not necessarily satisfactory.
ここに、従来のスリツト型メツキ液吹出し装置

度上問題点も多く加工経費も高い。 As is clear from Fig. 1, a slit-shaped aperture plate 3 is provided on the header 2 so as to cross the running direction of the strip 1, and the plating liquid is blown out through the slit 4 as shown by the arrow in the figure. . However, such a slit-type nozzle does not provide a uniform flow velocity distribution. That is, since the flow velocity of the plating liquid injected from the blowing device has a main stream velocity vector component of the flow velocity of the plating liquid in the head in the length direction of the header 2 as shown in FIG. The composite vector with the injection velocity vector when the velocity is 0 becomes the actual ejection flow velocity vector, and therefore, above the blowing device, a biased flow of the plating liquid as shown by the broken line in FIG. 2 occurs. Therefore, non-uniform distribution of the plating liquid flow rate occurs in the width direction of the strip 1. Furthermore, when machining a blowing device with a header length of about 2000 mm and a slit width of about 10 mm, there are many problems with machining with machine tools and machining accuracy, and the machining cost is high.

出し装置である。(Means for solving the problem) Since the plating liquid flow in the header is an unavoidable element, the present inventors have made the above-mentioned main flow velocity vector based on this flow as small as possible. As a result of various studies on header structures for this purpose, the present invention was completed. a header, a plurality of holes for blowing out plating liquid installed in at least one row along the longitudinal direction of the header at unequal intervals and/or with unequal diameters; at least one collision plate installed along the header and causing the plating liquid injected from the hole to collide with the header; This plating liquid blowing device is characterized by comprising a plurality of guide plates spaced apart from each other and provided at appropriate positions between the plurality of holes.

ように先細りのテーパ形状が望ましい。(Function) To further explain the present invention with reference to the drawings, the plating liquid blowing device according to the present invention has a cylindrical plate connected to the plating liquid supply pipe as appropriate, as shown in a schematic cross-sectional view in Fig. 3. A plurality of holes 11 are formed, for example, at irregular intervals in the longitudinal direction of the header 10, and a guide plate 12 is installed between the holes 11. Guide plate 1 with holes 11
It is desirable that the tip of No. 2 has a tapered shape as shown in FIG. 4, which is also a schematic cross-sectional view.

することを１つの特長としている。 In this way, in the present invention, the shape of the blowout outlet of the blowout device is not the conventional slit shape described above but the shape of the hole 11, thereby removing the velocity component of the flow velocity in the header width direction and preventing drifting. This is one of its features.

１３を設けてもよい。 Further, according to the present invention, as shown in FIG. 4, the flow direction component of the jet jet injected from the hole 11 is removed by the guide plate 12. As a result, it is possible to prevent drifting more reliably and effectively, increasing the relative velocity between the plating liquid and the strip surface, and because there is less drifting in the width direction of the header, the quality is uniform across the header width. It is possible to efficiently produce products of high quality. Here, an auxiliary guide plate 13 may be provided for supporting and reinforcing the guide plate 12 and for rectifying the flow.

速度差を小さくし、より均一にする。 The header 10 is also provided with a jet collision plate 14 for colliding jets from the holes 11.
The jet flow flowing out from the blowout device collides with the flow jet collision plate 14 to create a radial jet flow, thereby reducing the speed difference in the width direction of the blowing device and making it more uniform.

に差のない均一なメツキ層が得られる。 That is, FIG. 5 shows changes in the velocity distribution of the jet in the x direction when there is no collision plate. On the other hand, FIG. 6 shows changes in the velocity distribution of the jet in the x direction when the collision plate 14 is provided. First, it can be seen from FIG. 5 that the velocity distribution gradually expands in the y direction in proportion to the distance from the hole 11 in the x direction. However, if the collision plate 14 is provided as shown in FIG. A velocity component in the y direction suddenly appears in the jet (referred to as a point), and a jet having a uniform x-axis velocity distribution with very little variation in the strip width direction is obtained. Therefore, the flow velocity vector is uniform in each part of the board width, and a uniform plating layer with no difference in the adhesion state of plating in the board width direction can be obtained.

なければならない。 It can thus be seen that the present invention provides a more uniform velocity distribution of the plating solution by providing holes, guide plates and impingement plates, respectively. In order to ensure this effect, the mutual arrangement of the above-mentioned elements must be appropriate.

In FIG. 7b, the holes 11 are arranged in a row at equal intervals. The diameter of the hole 11 gradually decreases. On the other hand, in Fig. 7c, the hole 11 is 2
They are spaced unevenly in rows.
本発明の別の態様によれば、複数の孔のそれぞ

板で取り囲まれているように構成してもよい。 According to another aspect of the invention, each of the plurality of holes may be surrounded by a corresponding collision plate and guide plate as described above.

つた曲面とする。 FIG. 8 is a schematic perspective view of the plating liquid blowing device according to the present invention. In the illustrated example, the guide plate is attached at right angles to the outer peripheral edge of the header, but has a curved surface. . This curved surface is preferably a curved surface along the outer periphery of the header 10 in which the hole 11 is provided.

ようにするのが望ましい。 In the present invention, the plating liquid supply pipe and the header may be installed in such a way that the plating liquid flows into the header from one end and flows out from the other end, or the plating liquid may flow into the header from both ends or from the center. All the plating liquid may flow out through the holes 11. From the point of view of reducing the flow velocity vector of the plating liquid in the flow direction within the header as much as possible, it is desirable that all the plating liquid flows out from the holes 11.
