Abstract

The invention belongs to the field of electric fluid dynamics spray printing, and discloses a complex surface circuit conformal spray printing method and equipment. The equipment comprises a spherical motor module, a translation module and a conformal spray printing module. The translation module drives the spherical motor module to move in an X-axis direction and a Y-axis direction in a plane; the conformal spray printing module comprises a spray head part and an electric signal part; the spray head part moves up and down so as to realize a freedom degree of a Z-axis direction; the electric signal part applies voltage on an ink fluid and an electrode ring in an ink cartridge; the spherical motor module rotates around the X-axis direction, the Y-axis direction and the Z-axis direction so as to realize six-degree-of-freedom motion of an object to be spray-printed; a curve surface base plate is grounded, so that the electric potential of the object to be sprayed-printed is zero; and the voltage applied in the ink fluid is higher than the voltage applied in the electrode ring, so that a gradient electric potential difference is formed on the ink fluid, the electrode ring and the object to be spray-printed. Through the complex surface circuit conformal spray printing method and the equipment provided by the invention, a conformal patterning electric spray-printing process of a complex surface is realized, an application range of the electric spray-printing process is improved, the manufacturing cost is reduced, and the printing accuracy is improved.
