Melt electric writing curve printing device and method based on translation-rotation cooperative motion

Abstract

This invention belongs to the field of melt electro-writing printing technology, and relates to a melt electro-writing curve printing device and method based on translational-rotational coordinated motion. The device includes a nozzle, a collection plate, a high-voltage generator, a composite motion platform, a vision monitoring unit, and a control system. The composite motion platform carries the collection plate and is jointly driven by a translational module and a rotational module located below it. The translational module drives the composite motion platform to perform planar translational motion, and the rotational module drives the translational module and the collection plate to rotate together around a vertical fixed axis. The method consists of: S1: Determining and initializing printing process parameters; S2: Path planning and motion parameter preprocessing; S3: Coordinated motion printing and real-time feedback control. The device of this invention fundamentally solves the accuracy and consistency problems existing in melt electro-writing printing of complex curve structures; the method of this invention improves printing accuracy.
