Abstract

The invention discloses a jet electro-deposition device capable of accurate control through air compression. The device comprises a three-dimensional motion platform, a deposition tank, an anode cavity, a nozzle, an anode bar, a pulse power supply, an air compressor and a PLC motion control system; the three-dimensional motion platform is provided with an X-Y-axis platform and a Z-axis platform; the deposition tank and the anode cavity are fixedly mounted on the X-Y-axis platform and the Z-axis platform respectively; the nozzle and the anode bar are fixedly mounted at the bottom and the interior of the anode cavity respectively; the air compressor is connected with the anode cavity through an air inlet pipe; and the PLC motion control system is electrically connected with the three-dimensional motion platform. According to the jet electro-deposition device, the air compressor is used for providing pressure for jet of a plating solution for electro-deposition jet, meanwhile, a pressure regulating valve is used for precisely controlling the jet flow speed of the plating solution, and therefore precise stepless regulation of the jet flow speed of the plating solution is achieved, and the regulation precision is higher than that of a traditional hydraulic pump.

Description

technical field [0001] The invention belongs to the technical field of spray electrodeposition, and in particular relates to a spray electrodeposition device with precise air compression control. Background technique [0002] Spray electrodeposition technology is a technology that sprays the electroplating solution containing high concentration of metal ions to the surface of the cathode in a high-speed jet for electrodeposition. Because the high-speed jet improves the mass transfer conditions and has a special electric field and flow field, the jet electrodeposition The deposition greatly improves the limiting current density, improves the deposition efficiency, refines the crystal grains and obtains a good quality deposition layer. [0003] However, the existing problems of spray electrodeposition mainly lie in: (1) those with simple structure and easy operation have low deposition efficiency and accuracy; (2) those with high deposition efficiency and accuracy have complex...
