Problems solved by technology

[0004] In the electrofluid spray film-making process, the control accuracy of the ink path is high. The traditional single-port air pressure ink supply system cannot realize the function of removing air bubbles. Although the mechanical force ink supply system can discharge air bubbles through pressure, it cannot achieve micro-flow control. Therefore It is necessary to develop the supporting ink supply system for import and export nozzles

Abstract

The invention discloses a blow head ink supply system with an inlet and an outlet. The blow head ink supply system comprises a positive pressure unit, a negative pressure unit, a flow adjusting unit and a control unit, wherein the positive pressure unit and the negative pressure unit are connected with the flow adjusting unit, the positive pressure unit and the negative pressure unit are used for providing a pressure source for the flow adjusting unit, the flow adjusting unit is connected with the control unit and used for micro-flow ink supply of an ink box and a liquid path, and the control unit is used for controlling switching of blow head ink supply, bubble discharging and recycling. The system can achieve the functions of ink supply flow control, bubble discharging of a blow head, recycling of cleaning ink and the like, and has the advantages of being convenient to control and high in precision and stability.

Description

technical field [0001] The invention relates to the related technical field of electrofluid spray film formation, in particular to an ink supply system with an inlet and outlet nozzle. Background technique [0002] With the development of nanotechnology, electrofluid spray film formation, as the most promising process method for preparing micro-nano-scale thin films, has attracted widespread attention from academic and industrial circles. The basic principle of electrohydrodynamic spray is based on electrohydrodynamic spray, that is, the ink is activated under a high-voltage electrostatic field of several thousand to tens of thousands of volts, so that it is dispersed into a large number of micro-nano-scale droplets, and evenly spread on the surface where the film needs to be formed. on electronic chips or other components. The preparation objects include semiconductor photoresist films, flat panel display glass coatings, organic packaging layers, metal films, photoelectric...
