JP4695283B2 - Edge mask device in electroplating tank - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an edge mask device disposed in an electroplating tank for continuously electroplating a strip surface.
[0002]
[Prior art]
When performing electroplating by transporting the strip between the electrodes of a continuous electroplating machine, the strip is prevented from being over-plated on the side edges of the strip, and the back of the current is prevented. For example, in Japanese Patent Publication No. 60-31093, an edge mask that can be moved according to the width of a strip is arranged. A continuous electroplating apparatus is described in which a roll-up curtain is connected between a tank sidewall and an edge mask.
[0003]
[Problems to be solved by the invention]
In the edge mask described in the above publication, since sludge in the plating solution accumulates on the curtain during operation, problems such as deterioration of productivity by stopping the operation of the edge mask due to defective winding or breakage of the curtain, etc. There is.
[0004]
Accordingly, the present invention provides an edge mask device that is disposed in an electroplating apparatus that can improve productivity by eliminating the curtain with many failures and smoothing and stabilizing the operation of the edge mask. .
[0005]
[Means for Solving the Problems]
The edge mask device in the electroplating tank of the present invention has a pair of electrodes and edge masks arranged so as to surround the strip running in the electroplating tank, and the electrodes and edge mask are arranged on one side of each electrode. An edge mask is provided integrally with the end portion so as to be movable in accordance with the width of the strip.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The edge mask device of the present invention can be applied to either a vertical electroplating tank or a horizontal electroplating tank.
[0007]
【Example】
Example 1
FIG. 1 shows an embodiment of the present invention and is a perspective view of a vertical type plating tank.
In the vertical plating tank 1, there are disposed electrode / edge masks 3a and 3b surrounding the strip 2a traveling upward and the strip 2b traveling downward.
[0008]
Respective electrode / edge masks 3a and 3b are formed by integrating concave edge masks 5a and 5b so as to face one side end of each electrode 4a and 4b. It is configured to slide on the surfaces of the opposing electrodes 4a and 4b.
[0009]
Shift bases 6a and 6b are fixed to the respective electrode / edge masks 3a and 3b, and the shift bases 6a and 6b are connected to cylinders 7a and 7b.
[0010]
The cylinders 7a and 7b advance and retreat the electrode / edge masks 3a and 3b to which the shift bases 6a and 6b are fixed along the guide rods 8a and 8b according to the width of the strips 2a and 2b.
[0011]
Next, the operation of the electrode / edge mask will be described.
[0012]
2A is a cross-sectional view showing a state in the case of a wide strip, and FIG. 2B is a cross-sectional view showing a state in the case of a narrow strip.
[0013]
2A, in the case of a wide strip, the electrode / edge masks 3a and 3b are retracted and opened so that the edge masks 5a and 5b are positioned on both sides of the strip 2a (2b).
[0014]
When the strip 2a (2b) is changed to a narrow strip, as shown in FIG. 2 (b), the electrode / edge masks 3a and 3b move forward to reduce the width, and the edge masks 5a and 5b are stripped. It is located on both sides of 2a (2b).
[0015]
Example 2
FIG. 3 shows another embodiment of the present invention and is a perspective view in the case of a horizontal type plating tank.
[0016]
In the present embodiment, the edge mask device of the first embodiment is horizontally arranged. The same members as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0017]
In this embodiment, the electrode / edge masks 3a, 3b are moved forward or backward in accordance with the width of the strip 2c with respect to the strip 2c running horizontally so that the edge masks 5a, 5b are positioned on both sides of the strip 2c. .
[0018]
【The invention's effect】
According to the present invention, since the curtain is eliminated, the operation is not stopped due to defective winding or breakage of the curtain, and the productivity can be improved.
[0019]
In addition, the integrated structure of the edge mask and the electrode makes the structure simpler than in the prior art and improves the maintenance.
[Brief description of the drawings]
