Abstract

The invention belongs to the field of electrohydrodynamic jet printing, and discloses a conformal jet printing method and equipment for complex curved surface circuits. The equipment includes a spherical motor module, a translation module and a conformal printing module, and the translation module drives the spherical motor module to move in the X and Y axis directions in the plane; the conformal printing module includes a nozzle part and an electrical signal part , the nozzle part moves up and down to realize the degree of freedom in the Z-axis direction, the electrical signal part applies voltage to the ink in the ink cartridge and the electrode ring; the spherical motor module rotates around the X, Y and Z directions to realize the six-degree-of-freedom movement of the object to be printed, and the curved surface The substrate is grounded so that the potential of the object to be printed is zero, and the voltage applied to the ink is higher than the voltage applied to the electrode ring, so that a gradient potential difference is formed on the ink, the electrode ring and the object to be printed. Through the invention, the conformal patterned electrojet printing process of complex curved surfaces is realized, the application range of the electrojet printing process is improved, the manufacturing cost is reduced, and the jet printing precision is improved.
