Ultrasonic barrel plating technique and device thereof

Abstract

The invention relates to a barrel plating device with the function of ultrasonic vibration, aiming at overcoming the defects that as plating solution is limited by a roller cavity when passing in and out a roller in the traditional barrel plating device, the plating layer effect of micropore and deep-hole parts is poor, and the like. The device mainly comprises a plating bath, an electrode, the roller, an ultrasonic generator and the like, wherein the ultrasonic generator is installed inside a fixed hollow shaft or a hollow electrode in the center of the roller, so that ultrasonic vibration can be effectively generated in the plating process, the dynamic balance of the plating solution is realized, and the deep plating effect and the compactness of a plating layer are improved.

Description

(1) Technical field

[0001] The invention relates to a new barrel plating process and equipment, especially barrel plating for plated parts that are difficult to obtain a good coating. (2) Background technology

[0002] As a kind of electroplating, barrel plating has been widely used. In rolling, single-barrel barrel plating machine is widely used. It is mainly composed of two parts: a barrel and an electroplating tank. The barrel is the container for the workpiece. At the same time, it is required to The liquid enters and exits freely. When working, the drum rotates in the electroplating tank, and the plating solution is exchanged with the electroplating solution in the electroplating tank by flowing in and out; The component and the conductive component provide rotation power to the drum and conduct working current. However, since the plating solution enters and exits the drum is restricted by the design of the holes on the drum, and the design of the voids, such as size a...
