Abstract: A conformal printing device for curved-surface circuits is provided. The device includes a device body that includes a stand and a support plate movable relative to the stand. The device further includes a print-head module mounted on the support plate and a motion module mounted on the device body. The print-head module includes a piezoelectric nozzle and an airflow assisting structure for applying an assisted airflow to guide charged jet ejected from the nozzle to be precisely printed onto a curved-surface base material below the nozzle. The motion module enables a tangent of a surface, on which a printing position of the curved-surface base material to be printed is located, to be always perpendicular to a jet ejected by the nozzle, ensures that the print-head module moves following the curved-surface shape, and implements conformal printing circuits on any complex curved surfaces.
