The control device comprises a precise injection pump (1), an X-Y-Z-axis movement platform (10), a fixed support (9) of a platform rotating around a Y axis, the platform (8) rotating around the Y axis, a platform (7) rotating around an X axis, an electrospinning collector, a micro-current detection circuit (24) and a high-voltage direct-current power supply (16). According to the control device and the control method, jet flow starting and stopping are precisely controlled, and production quality is guaranteed. The problems that in the existing near-field electrospinning process, initial jet flow is instable and hard to control, and when the jet flow enters in a stable state cannot be predicated are solved. The electrospinning jet flow fast stabilization control device for micro-nano machining and the control method of the electrospinning jet flow fast stabilization control device are convenient to implement and practical.

Description

technical field [0001] The invention relates to a micro-nano processing electrospinning jet rapid and stable control device and a control method thereof, and belongs to the innovative technology of the micro-nano processing electrospinning jet rapid and stable control device and the control method thereof. Background technique [0002] Electrospinning technology Electrospinning technology was first proposed by Formhzls in 1934, and then Taylor et al. proposed the concept of Taylor cone for the deformation of charged polymers in the electrospinning process in 1964. It was not until the 1990s that people began to Extensive attention has been paid to electrospinning technology. However, nanofibers produced by electrospinning are difficult to collect in an orderly manner, and it is also difficult to arrange them in an orderly manner. In 2006, Sun Daoheng and others proposed the near-field electrospinning direct writing technology. The electrospinning direct writing technology b...
