Coating controllable electroplating system

Abstract

The invention discloses a coating controllable electroplating system. Anode clamps and cathode clamps are respectively arranged on supporting insulating boards, a cathode corresponds to an anode to form a workpiece combination, at least one power sub machine is arranged on each supporting insulating board, the anodes are electrically connected to positive poles of the output ends of the power submachines, the cathodes are electrically connected to negative poles of the output ends of the power sub machines, the anodes and the cathodes respectively extend into an electrolytic solution hold ina plating tank, and each group of the anode and the cathode forms an independent circuit respectively; during electroplating, an electroplating current only needs to flow from the anode to a cathode workpiece in the independent workpiece combination, the scale of an electric field is much smaller than that of a traditional electric field, interference is little, and the uniformity of a coating onthe surface of the cathode workpiece is improved; workpieces do not affect mutually, as long as each independent workpiece combination is controlled to consistent set parameters including an electroplating current value, electroplating time, a distance between the workpieces and the anode, etc., and thus all workpieces can have coatings more tended to be consistent after electroplating.

Description

technical field [0001] The invention relates to the field of electroplating technology, and further relates to a coating controllable electroplating system. Background technique [0002] In the traditional electroplating process, all anodes (anode titanium basket or insoluble anode) are placed on both sides of the electroplating tank, and the workpiece as the cathode passes through the middle of the anodes on both sides. When the electroplating current flows from the anode to the cathode through the electroplating solution, The coating will be formed on the surface of the workpiece. However, in this form of electroplating process, since the scale of the entire electroplating activity exists between all workpieces and all anodes, the coating distribution and thickness of different workpieces will have a certain degree of difference, that is, there will be some variation. [0003] On the other hand, workpieces of different sizes will have different electroplating areas, so di...

However, in this form of electroplating process, since the scale of the entire electroplating activity exists between all workpieces and all anodes, the coating distribution and thickness of different workpieces will have a certain degree of difference, that is, there will be some variation

[0003] On the other hand, workpieces of different models and sizes will have different electroplating areas, so different electroplating currents are required. Since the electroplating current flows from the positive output of the high-power electroplating rectifier to the anodes on both sides of the electroplating tank, the current loops of all workpieces are Connected together, connected back to the negative output of the high-power electroplating rectifier, so the electroplating current will flow to each workpiece in the electroplating tank, so the user can only control the total electroplating current of all workpieces as a whole, but cannot independently control the receiving power of each workpiece The plating current

Therefore, in the traditional continuous electroplating production line, the anode is generally set to output the calculated specific total electroplating current value, and then the cathode in the middle of the electroplating tank needs to be exactly the same model and the specified number of workpieces are electroplated, so the flexibility of production very low
