Array-integrated-type spray printing device and method with adjustable spatial distribution

Abstract

The invention belongs to the technical field of spray printing devices, and particularly discloses an array-integrated-type spray printing device and method with adjustable spatial distribution. The array-integrated-type spray printing device comprises a box, spraying head sets arranged in the box and distributed in an arrayed mode, and moving assemblies used for adjusting the positions of spraying heads. The spraying heads in the spraying head sets comprise fixing joints, connectors, intermediate joints and output heads, wherein the fixing joints, the connectors, the intermediate joints and the output heads are sequentially arranged from top to bottom. Through holes and gas input channels are formed in the intermediate joints; quartz pipes penetrating out of the lower ends of the output heads are mounted in the through holes, outlets of the quartz pipes serve as nozzles, and high-pressure electrodes are inserted in the quartz pipes; gaps are reserved between the high-pressure electrodes and the quartz pipes; and the hollow parts of the high-pressure electrodes serve as ink liquid channels. Each set of spraying heads is provided with the corresponding moving assembly, the moving assemblies are used for mounting the spraying heads and adjusting the positions of the spraying heads, and electrode plates and ultraviolet lamps are arranged in the box. The array-integrated-type sprayprinting method is conducted through the array-integrated-type spray printing device. Large-scale production is achieved, meanwhile, the flexibility of the array-integrated-type spray printing deviceis greatly improved, and the application range of the array-integrated-type spray printing device is greatly enlarged.

Description

technical field [0001] The invention belongs to the technical field of jet printing devices, and more particularly relates to an array-integrated jet printing device and method with adjustable spatial distribution. Background technique [0002] Electrojet printing technology is widely used in wearable communication devices, thin film transistors, advanced flexible clinical surgical tools, bioelectronic cameras, displays, and solar photovoltaic cells. The basic principle of electrojet printing is to apply high-voltage positive potential and high-voltage negative potential to the nozzle and the substrate respectively, and use the electric field to pull out the ink in the nozzle and atomize it, and the atomized ink particles are deposited on the substrate to form a thin film. Electrojet printing has the following characteristics: the voltage between the nozzle and the substrate is adjustable, and the deposition efficiency of the ink can be controlled by controlling the electric...

AI Technical Summary

Problems solved by technology

[0003] However, there are some problems in the existing electrojet printing technology: First, the ink droplets formed by electrojet printing atomization form a cone between the nozzle and the substrate, so what is deposited on the substrate is a circle, when it is to be printed When the substrate is square, there will be dead corners that cannot be printed, and the printed film will show a tendency to be thick in the middle and thin at the edge, which seriously affects the flexibility, efficiency and quality of the film; secondly, the existing Most of the current electrojet printing equipment is a single nozzle device, and the integration level is not high, which greatly affects the processing efficiency; in addition, in the existing inkjet printing process, it is sometimes necessary to modify and etch the material while printing the material, and the current The electrojet printing equipment cannot realize this function
