Electroplating device for three-dimensional metal workpiece and process thereof

Abstract

The electroplating device comprises liquid circulating mechanisms arranged on the two sides of a cleaning pool, and a clamping and conveying mechanism used for driving the three-dimensional metal workpiece to be soaked and moved is arranged in the cleaning pool. The liquid circulation mechanism drives the clamping end of the clamping conveying mechanism to rotate so that the three-dimensional metal workpiece can move in the cleaning pool in a rotating mode. The clamping conveying mechanism comprises a lower driven wheel arranged at the feeding end of the cleaning pool and an upper driving wheel arranged at the discharging end of the cleaning pool, the upper driving wheel and the lower driven wheel are connected through a driving chain, and a plurality of evenly-distributed multi-direction rotating clamping assemblies are installed on the two sides of the driving chain correspondingly. The two multi-direction rotating clamping assemblies which are matched in position and form a group are connected through the tensioning elastic rope, the side face of the single multi-direction rotating clamping assembly is connected with the driving chain through the rotating stretching assembly, the metal workpiece cleaning and transferring work is achieved, and pollution to electroplating liquid of a follow-up plating layer is avoided.

Description

technical field [0001] The invention relates to the technical field of metal electroplating, in particular to an electroplating device and process for three-dimensional metal workpieces. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. The outer layer of many coins is also electroplated. [0003] The existing electroplating device is to set electroplating and cleaning on the same production line, that is, to set up multiple electroplating pools and cleaning pools in series, use the gantry to drive the metal workpiece to immerse into the electro...
