Description

[Detailed description of the invention] The present invention relates to a continuous electroplating device for striatal bodies.
It is useful for electroplating strips.

As a device for continuous electroplating of the striatum, the first
As shown in the figure, two mutually parallel support shafts 21', 22' are provided at the upper part of the plating tank 1', and on these support shafts 21', 22', as shown in FIG. ' is supported in a coiled manner, and the support shaft 2
There is a known device in which the filament body a' is rotated and advanced by the rotation of the filament elements 1' and 22'. In FIG. 1, 3' is an anode as a plating material, for example, a copper anode, and 4', 4' are contacts for electrically connecting the support shafts 21', 22' to the negative electrode of the power source.

In the above case, if the filament a' comes into contact with the anode 3', it becomes difficult for the filament a' to move forward smoothly, and the plating quality is also adversely affected.

However, if the filament has a circular cross section, the moment of inertia of the area is large and the filament can be held in a substantially circular coil shape, so the above contact does not occur. If the body is striated,
Since the moment of inertia for coil bending is small, the coil shape becomes elongated due to its own weight, and the bottom of the coil tends to come into contact with the anode, which poses a problem.

The present invention is designed to easily prevent the above-mentioned coil bottom from coming into contact with the anode even if the filament is a strip.

That is, the device for continuous electroplating of a filament body according to the present invention supports a filament body as an object to be plated in a coil shape on two mutually parallel support shafts, and rotates the filament body by rotating the support shaft. In this electroplating device, which rotates and moves forward, the structure is characterized in that a filament presser roll is provided between the support shafts.

The present invention will now be described with reference to the drawings.

FIG. 3A is an explanatory longitudinal sectional view showing the device of the present invention, and FIG. 3B is an enlarged perspective view of portion B in FIG. 3A.

In FIG. 3A and FIG. 3B, 1 is a plating tank. Reference numerals 21 and 22 denote two support shafts parallel to each other provided at the upper part of the plating tank 1, and are in contact with the negative electrode of the power source via the contactor 3. 4 is an anode as a material to be plated, for example, a copper anode. Reference numeral a denotes a strip as an object to be plated, which is supported in a coil shape by the support shafts 21 and 22 mentioned above. Reference numeral 5 denotes a filament presser roll, which applies a moment to the filament between the support shafts 21 and 22 in a direction from outside between the support shafts to a direction that wraps around between the support shafts.

In the above, the coiled strip a is rotated and advanced by the rotation of the support shafts 21 and 22. However, since the moment M generated by the presser roll 5 is in the direction of lifting both the left and right sides of the coil shape, the bottom of the coil shape can be moved upward by that amount, and the filament has a moment of inertia of area (the above-mentioned Even if the strip has a small moment of inertia with respect to the bending direction of the coil, contact between the coil bottom a ₀ and the anode 4 can be prevented.

In the above, the presser roll 5 was provided in the center between the support shafts 21 and 22, but as shown in FIG.
5 may be provided to apply the moment M in the predetermined direction to the strip a.

As described above, according to the present invention, a filamentous body as an object to be plated is supported in a coiled manner between two mutually parallel support shafts, and the coiled filamentous body is transferred to a plating tank by rotation of these support shafts. Even if an electroplating device that moves forward while rotating inside the strip is used for plating the strip, contact between the bottom of the coil of the strip and the anode in the plating tank can be prevented, and the strip will be It is possible to perform plating smoothly even in the case of
