Problems solved by technology
[0004] There are currently two main problems in electrohydrodynamic jet printing encapsulation technology. One is that the non-wetting material substrate has a weak adhesion to the encapsulation solution, which makes the encapsulation structure easy to fall off from the substrate. The other is how to effectively control the internal and external dimensions of the encapsulation structure. the size of

The invention discloses a control method and equipment for electrohydrodynamic jet printing and wrapping microstructures, which include a controller, an industrial camera and a base, a substrate arranged on the base, an XY moving platform is arranged on the base, and the The XY mobile platform is equipped with a coaxial nozzle that can slide in the Z direction. The coaxial nozzle is provided with a ring laser in the circumferential direction. The ring laser is tightly and uniformly distributed by several laser heads. On / off, power and pulse frequency of each laser head. A ring laser is arranged at the end of the coaxial nozzle in the circumferential direction. During the electrohydrodynamic coaxial jet printing process to wrap the microstructure, the ring laser is used to locally melt the substrate on the jet printing path, causing the substrate to form a microstructure in a molten state. Therefore, the encapsulation microstructures of electrohydrodynamic coaxial jet printing are better attached to the substrate, and the adhesive force of the substrate is increased.
Description
technical field [0001] The invention belongs to the technical field of electrohydrodynamic jet printing, and in particular relates to a control method and equipment for wrapping microstructures by electrohydrodynamic jet printing. Background technique [0002] Electrohydrodynamic jet printing technology is a micro-nano-scale preparation technology that utilizes electrohydrodynamic effects to deposit functional material patterns on substrates. With the advantages of high efficiency, large processing area, no template, simple process, non-contact, and environmental protection, it has broad application prospects in the fields of flexible electronics, biomedicine, optical devices, tissue engineering, biological scaffolds, and energy. [0003] The electrohydrodynamic jet printing technology mainly realizes the microstructure preparation of a single material through the single nozzle mode. In order to realize the microstructure preparation of two or more materials, the coaxial ele...
