Description
Technical field
The utility model relates to a kind of electroplanting device, is specifically related to a kind of plating tank with circulation filter, for improving electroplating quality and efficiency.
Background technology
Plating be mainly used to improve product corrosion stability, wear resistance, decorate or make product have certain function, it is widely used.Plating refers in the saline solution containing pre-metallizing, with plated matrix metal for negative electrode, by electrolytic action, the positively charged ion of pre-metallizing in plating solution is deposited in base metal surface, forms a kind of method of surface finish of coating.Coating performance is different from matrix metal, has new feature.Plating is exactly the process utilizing electrolysis principle to plate other metal or alloy of skim on piece surface, is the technique of the surface attachment layer of metal film of the part utilizing electrolysis principle that metal or other material are made.Electroplate the difference according to plating, the electroplating technology groove arranged also is not quite similar, but before the electroplating process that general plated item completes an electroplating technology groove enters next electroplating technology groove, all to wash at washing bath, the effect of washing bath is the residual electroplate liquid wash clean above workpiece, do not affect lower one technique to carry out, do not pollute electroplate liquid in lower one plating tank, thus ensure the quality of plating.
In order to ensure the quality of coating, except the processing parameters such as strict temperature control, current density, PH, also must pay attention to the factors such as the impurity in stirring and electroplate liquid to the impact of plating quality, in order to prevent the concentration polarization of bubble when coating surface is detained and electroplate, the mode of usual employing mechanical stirring or pneumatic blending, or adopt circular flow mode to promote the circulation of electroplate liquid.It is one of important measures ensureing plated item quality that electroplating solution filters.
In existing Electroplating Production, the filtration of electroplate liquid, normally arrange a filter, the inlet pipe of filter is fixed on the bottom of plating tank, goes out the top that pipe is fixed on plating tank, this just makes filter working load large, cannot be clean by the contaminant filter being deposited on bottom land and swim on liquid level, easily cause workpiece contamination, the electroplate liquid loss caused in electroplate liquid working cycle is difficult to accomplish quantitatively to supplement, make the effect of plating very uneven, affect quality product.
The auxiliary agents such as leveling agent, promotor, control agent are nonionic surface active agent, and the emulsion formed has unusual solubleness, in unsure state in electroplate liquid, can progressively decompose.The circulation stirring Shaoxing opera of electroplate liquid is strong, more easily decomposes, and decreases the ageing of electroplate liquid.So in plating, the drop reducing electroplating solution of cyclic filtering and the severe degree controlling electroplate liquid stirring are even more important.If auxiliary agent is superfluous in electroplate liquid, the effect that meeting inhibit activities core is grown up will decline and be difficult to obtain fine and close plated film, thus causes the physical property of epithelium to decline, and produces sometimes and declines to the precipitation inhibition on plating piece surface, thus make all to plate the problems such as variation.
In electroplating processes process, according to the production of plating, need in the titanium basket of electroplating device, constantly add metal and add liquid medicine in groove, through liquid medicine electrolytic metal to decomposite metal ion, be attached on plated item.The metal added such as copper ball also can produce the impurity such as copper ashes, copper wire when decompositing cupric ion, and these impurity can affect quality of item, causes quality bad so that the problem such as to scrap.
