Description

Electroplating equipment

Technical Field

The invention relates to the technical field of electroplating, in particular to electroplating equipment.

Background

The electroplating process adopted by the electroplating equipment is a process for plating a thin layer of other metals or alloys on the surfaces of certain metals by utilizing an electrolysis principle, and is a process for attaching a layer of metal film on the surfaces of the metals or other material parts by utilizing an electrolysis effect so as to play roles of preventing metal oxidation (such as corrosion), improving wear resistance, conductivity, light reflection, corrosion resistance (such as copper sulfate and the like), improving the appearance and the like.

Along with the high-speed development of global electronic products, the requirement on the manufacturing precision of circuit boards is higher and higher, and an insoluble anode plating line is adopted for electroplating of the buried pore plates, so that the hole filling capacity is high, and the electroplating uniformity is good. And insoluble anode plating is also adopted in the fields of new energy and copper foil manufacturing. Has wide market prospect.

The existing industry adopts electroplating-grade oxidized metal powder (such as copper oxide) to stir and dissolve to provide metal ion consumption during electroplating, the dissolving speed is general, and the cost is high; in addition, the consumption of the oxidized metal powder and the consumption of the plating metal ions cannot be precisely controlled, and the plating quality is unstable due to more or less metal ions. Therefore, there is a need to develop a method for providing metal ions for electroplating, which can effectively reduce the cost and satisfy the requirements of the process and quality.

Meanwhile, the traditional electroplating equipment is of a structure with an independent anode and an independent spray pipe, so that the electroplating equipment is complex in disassembly and assembly steps, inconvenient to maintain and high in energy consumption. The prior anode device for spraying current also has the problem that the sprayed electroplating solution can not uniformly and comprehensively cover the cathode plate, thereby influencing the electroplating quality. Therefore, the drawbacks are obvious, and it is highly desirable to provide a solution.

In addition, the conductive roller and the plating anode of the conventional plating apparatus form a loop, that is, the conductive roller is plated simultaneously, and the plating metal is plated on the conductive roller during a long time operation to make the surface of the conductive roller uneven, thereby generating a hump effect, affecting the plating quality and increasing the maintenance frequency.
