Preparation method of novel efficient electroplating roller

Abstract

The invention relates to a preparation method of a novel efficient electroplating roller for electroplating a metal workpiece. A negative pole connector is arranged in a central shaft part at one end outside the roller designed, a columnar negative pole contact is arranged in the roller, and the negative pole contact is connected with the negative pole through a lead. The preparation method provided by the invention has the beneficial effects that after the roller designed by the invention is connected through the negative pole connector, the current turn volume is increased, and the electroplating workpiece in the roller is uniform in plating layer and ideal in effect.

Description

[0001] technical field [0002] The invention relates to a method for preparing a cylinder used in electroplating. Background technique [0003] With the development of "surface technology", new electroplating processes and new electroplating equipment continue to appear. As far as the important equipment drum of barrel plating is concerned, there have been shaking drums, vibrating drums, and involute spiral drums. But at present, most of them are regular hexagonal immersion drums and inclined drums. After years of production practice, it has been proved that the regular hexagonal drum and the inclined drum are prone to metal ion poverty in the near cathode area, resulting in a concentration gradient in the electrolyte and a decrease in the cathode current efficiency. [0004] In the electrolyte, a larger current density is applied to the working roller, and metal ions Me will appear in the working area near the cathode. n+ poor area. Because in the electrolyte, the mass...
