Barrel plating device

Abstract

A barrel plating device includes a cylindrical drum which is immersed in a plating solution in a horizontal state and configured for containing objects to be plated; a support member for rotatably supporting the drum; a drive mechanism for rotatably drive the drum; and a conductive member in a shape of bar which is disposed coaxially with the drum and integrally rotate with the drum.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the foreign priority benefit under Title 35, United States Code, section 119 (a)-(d), of Japanese Patent Application No. 2006-120392, filed on Apr. 25, 2006 in the Japan Patent Office, the disclosure of which is herein incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a barrel plating device suitable for plating small objects.[0004]2. Description of the Related Art[0005]As for a barrel plating device for plating small objects, there has been known a device having: a horizontally and rotatably supported drum for holding objects to be plated therein; a plating bath for storing a plating solution in which the drum is immersed; a negative electrode which is held in the drum together with the objects to be plated; and a positive electrode disposed in the plating solution in the plating bath in such a manner that a periphery of the d...

AI Technical Summary

Benefits of technology

[0013]With this configuration, the drum and the bar-shaped conductive member integrally rotate. Therefore, a gap is not formed between the bar-shaped conductive member and the objects to be plated in the drum, which prevents a generation of a high-current-density part. As a result, there is prevented an occurrence of burnt deposit in a plating film formed on a surface of the plated object.

[0030]In addition, according to the present invention, there is provided a barrel plating device in which a replacement of the drum and introduction and removal of the objects are facilitated to thereby workability, and at the same time, the drum is stably rotated without coming off of a use position during the operation of the plating device.

Problems solved by technology

As a result, there arises a problem that burnt deposit may be occurred in a plating film formed on a surface of each of plated objects P facing the high-current-density part C.

Due to this structure, in order to put and remove the objects P to be plated, a face or a part thereof of the side wall 123 of the drum 102, for example, is made attachable and removable (not shown), leading to poor workability.
