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.

1 . A barrel plating device comprising:
 a cylindrical drum for containing objects to be plated and being immersed in a plating solution in a horizontal state;   a support member for rotatably supporting the drum;   a drive mechanism for rotatably driving the drum; and   a conductive member in a shape of a bar which is disposed coaxially with the drum and integrally rotates with the drum.   
   
   
       2 . The barrel plating device according to  claim 1 , further comprising an electrode shielding part comprising:
 an electrode electrically connected to the conductive member;   a housing for holding the electrode, in which an end part of the conductive member is inserted; and   a liquid-proof part for preventing the plating solution from entering the housing.   
   
   
       3 . The barrel plating device according to  claim 2 , wherein the electrode comprises:
 an electrode bar;   a conductor electrically connected to the conductive member; and   an elastic member for connecting the electrode bar with the conductor, and biases the conductor to the conductive member.   
   
   
       4 . The barrel plating device according to  claim 1 , wherein the drum is removably attached to the support member. 
   
   
       5 . The barrel plating device according to  claim 1 , wherein the drum has tapered portions formed in internal faces thereof. 
   
   
       6 . The barrel plating device according to  claim 1 , wherein the drum has lid parts on both ends, and at least a part of an inner face of the lid part exposed to an internal space of the drum has a plurality of grooves formed thereon. 
   
   
       7 . The barrel plating device according to  claim 1 , wherein the drum has rotational shafts on both ends, the shaft being rotatably supported by fixing means provided on the support member.
