Abstract:
1. A barrel plating apparatus, comprising: a barrel plating tank filled with an electrolytic solution; a barrel container immersed in the electrolytic solution of the barrel plating tank and filled with chip parts and media; a power supply unit for supplying current to an anode part and a cathode part which transfer the current to the barrel container and the electrolytic solution of the barrel plating tank; a driving motor for rotating the barrel container wherein the cathode part comprises a center bar connected to the power supply unit through cranks and formed in parallel with an internal axis of the barrel container along the internal axis; a cathode rod perpendicularly extending from the center bar to come into direct contact with the chip parts or the media; and a hall current sensor formed in the cathode rod to measure the current, and the center bar comprises a center bar insulating cover formed on an outermost portion of the center bar; a center bar copper pipe formed in the center bar insulating cover and configured to allow the current to flow therethrough; and a sensor wire formed in the center bar insulating cover and connected to the hall current sensor.
