Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electroplating process capable of mass-producing processed products having different shapes simultaneously with high quality.
[0002]
[Prior art]
Conventionally, when electroplating a workpiece having a different shape, the same shaped product is put into a barrel in order to eliminate variations in film thickness, and the different shaped product is processed with one barrel and one power source while changing the barrel. Was. In some cases, the post-processing process is divided in half using a split barrel for post-processing quality and to reduce the weighing load. Was added to adjust the surface area and weight to the left and right to eliminate variations in film thickness.
[0003]
[Problems to be solved by the invention]
However, in the conventional electroplating process, even if it is desired to mass-produce many kinds and small lots with one barrel and one power supply, it is necessary to process the products having different shapes for each barrel, so that the production efficiency can be increased. Did not. Also, since the left and right barrels can be of the same shape, the productivity does not change much. Rather, the plating barrel circulates poorly in quality in the barrel compared to the barrel because the plating solution in the barrel is poorer in quality. There were also quality problems such as the mixing of processed products.
[0004]
Accordingly, an object of the present invention is to provide a barrel, a barrel apparatus, and a processing method capable of efficiently mass-producing a large variety of small lots and performing high-quality electroplating processing without mixing.
[0006]
[Means for Solving the Problems]
According to the present invention, as a means for solving the above-mentioned conventional problem, a barrel (1) is divided into a left (2) and a right (3), and a gap (about 20 to 100 mm) into which a plating solution can enter. There is 4). As a plating barrel device, there is a rectifier (8) for the split barrel left (2), a left lead wire (9) on the cathode side, and a left anode plate (10) on the anode side. There is also a rectifier (11) for the split barrel right (3), a right lead wire (12) on the cathode side, and a right anode plate (13) on the anode side. I have.
The present invention is a divided barrel and a divided barrel device configured as described above.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
The barrel (1) according to one embodiment of the present invention is divided into a left (2) and a right (3), and the entire side surface of the barrel includes a hole that does not catch the processed product including the middle divided side surface. I am open to There is a gap (4) in the center of the plating solution into which a plating solution of about 20 to 100 mm can enter, thereby enhancing the plating solution circulation function during the electroplating process. In consideration of the installation space and prevention of mixing, the gap (4) is desirably set to about 60 mm. As a plating barrel device, there is a rectifier (8) for the split barrel left (2), a left lead wire (9) on the cathode side, and a left anode plate (10) on the anode side. There is also a rectifier (11) for the split barrel right (3), a right lead wire (12) on the cathode side, and a right anode plate (13) on the anode side. Therefore, it is possible to efficiently and efficiently perform the electroplating process on ones having different shapes simultaneously in one barrel.
[0008]
The present invention is not limited to the embodiments shown in the drawings, and various changes can be made without departing from the scope of the present invention. For example, in the present invention, an octagonal barrel is used, but a hexagonal barrel or a cylindrical barrel may be used. In the present invention, the anode plate is divided and independent in a one-barrel, two-power-supply system, but only the anode plate may be integrated into the left and right.

【The invention's effect】
ADVANTAGE OF THE INVENTION According to the division | segmentation barrel of this invention, and a 1 barrel 2 power supply division | segmentation barrel apparatus, the thing of a different shape can be electroplated simultaneously in 1 barrel, and a large number of goods and small lot goods can be mass-produced efficiently. Further, by providing a gap in the middle of the divided barrel, a high-quality electroplating process without mixing can be performed.
