Description

Electroplating bath structure for electroplating production

Technical Field

The utility model relates to a metal surface electroplates technical field, especially relates to an electroplate bath structure for electroplating production.

Background

The most basic equipment in the electroplating equipment is an electroplating bath, the main function is to install solution, the use mode of the electroplating bath is arranged according to the process flow production line of manual operation, and also arranged according to the field space separately according to local conditions, if the electroplating bath is a mechanical automatic production line, the electroplating bath is basically arranged according to the process flow, the electroplating bath is used for installing solution and is used for plating zinc, copper, nickel, gold and the like, the bath body can be made of a steel frame-lined polypropylene plastic plate, and the selection of the bath body structure depends on the factors of the property, the temperature, the electroplating mode and the like of the electroplating bath solution.

When the electroplating bath is used for electroplating metal workpieces, the electrolytic solution in the bath body needs to be ensured to be continuously and circularly stirred or the workpieces continuously move to accelerate the removal of hydrogen generated by cathode reaction, so that the hydrogen is prevented from being adsorbed and gathered on the surfaces of the workpieces to form bubbles, the bubbles isolate the electroplating solution to ensure that a plating layer cannot be deposited, the temperature, the concentration and the pH value of the solution in the electroplating bath are uniformly distributed, the electrode reaction blockage caused by spontaneous mass transfer deficiency is compensated, the limiting current density is improved, and the electrode reaction speed is improved while the electroplating quality is ensured. For a workpiece needing local rack plating, in order to ensure the smoothness of a coating and a non-coating interface and the height dimension precision of the coating, the smaller the fluctuation of the liquid level is, the better the fluctuation is, one way at present is to ensure the dimension precision of local plating by adopting static plating of a solution in a plating tank for avoiding the fluctuation of the liquid level of an electroplating solution, but is not favorable for the uniform distribution of the temperature, the concentration and the pH value of the solution in the plating tank, the electrode reaction is blocked due to insufficient spontaneous mass transfer, and the obtained coating, particularly the coating with thicker thickness requirement, has poorer quality; the other method is to adopt a liquid storage tank to circularly supply liquid to a sub-tank, but a liquid outlet pipe basically and directly extends into the sub-tank, so that the fluctuation of water flow around the liquid outlet pipe is large, the fluctuation of liquid level in the sub-tank aggravates the edge effect to cause the crystallization of a coating at the interface of a coating and a non-coating of a local electroplating workpiece to be thick, the coating is wavy and uneven, the thickness difference with the coating obtained under the liquid is large, meanwhile, the size precision of the local coating cannot be ensured, and the quality requirements of the coating thickness, the local size precision, the coating crystallization state and the like cannot be met.
