A stirring mechanism for electrodeposition

Abstract

The invention discloses a stirring mechanism for electro-deposition which comprises an electro-deposition tank, a cathode, a cathode moving mechanism and a stirring mechanism body. The stirring mechanism body comprises near cathode stirring paddles, far cathode stirring paddles, a near cathode suspension beam, a far cathode suspension beam and limiting seats. When the stirring mechanism works, a horizontal reciprocating moving beam drives the near cathode stirring paddles connected with the near cathode suspension beam and the far cathode stirring paddles connected with the far cathode suspension beam to do horizontal synchronous reciprocating movement; under the dual actions of the near cathode stirring paddles and the far cathode stirring paddles in the mechanism, an electrolyte solution near cathode planes and in the whole electro-deposition tank can be stirred uniformly at high intensity. The stirring mechanism for electro-deposition greatly improves the uniformity of thickness distribution of a deposition layer and is simple in structure and low in cost.

Description

A stirring mechanism for electrodeposition technical field The invention relates to the technical field of electrodeposition production equipment, in particular to a stirring mechanism for electrodeposition. Background technique At present, in industrial production, air stirring or cathode moving devices are mostly used for stirring the electrolyte of electrodeposition (including electroplating and electroforming). These two stirring methods have their own advantages and disadvantages. Generally speaking, it is easier to obtain a uniform mass transfer distribution on the cathode surface when the cathode is moved and stirred. However, the intensity of cathode moving and stirring is generally not high, and the global stirring effect on the entire electrodeposition tank is relatively low, resulting in generally low deposition rate and thickness distribution uniformity. The main reason is that the conventional cathode moving and stirring only uses the shearing action between ...
