Micro-area synchronous curing electronic injection printing device

Abstract

The invention belongs to the technical field of advanced manufacturing, and relates to a micro-area synchronous curing electronic injection printing device, which comprises a synchronous heating curing module, an electronic injection printing module and a motion adjusting module. Firstly, printing ink is output through an injection pump and conveyed into an electronic injection printing nozzle through a connecting guide pipe; meanwhile, a potential regulator enables the printing nozzle to have high potential; high voltage is formed between the printing nozzle and a moving substrate; when ink is conveyed to a nozzle of the printing nozzle, fine jet flow is formed under the action of electric field force, gravity and surface tension of the ink; in the printing process, the electric jet flows make contact with a printing substrate; meanwhile, a heating device conducts heating immediately; an organic solvent in the electric jet flows volatilizes rapidly; synchronous curing is achieved; furthermore, the heating device only heats a local area, making contact with the substrate, of the electric jet flows; and therefore, thermal deformation caused by heating to the printing substrate is greatly reduced. The micro-area synchronous curing electronic injection printing device disclosed by the invention can solve the problems of the traditional heating curing technology, and has the characteristics of low energy consumption, low cost and the like.

AI Technical Summary

Problems solved by technology

The traditional heating and curing technology is to heat the printing substrate as a whole, so that the printing ink can be cured and shaped. The ink shows the expected printing effect, and due to the thermal deformation of the printing substrate, the substrate and the printing structure may even break during the ink curing process
