A control device, device and method for controlling the resolution of electrohydrodynamic printing

Abstract

The present invention provides a control device and method and method of controlling current dynamic printing resolution. The control device that controls the dynamics of the dynamics of the body includes a magnetic field for the magnetic field to generate the magnetic field to Xinliangzi, and the magnetic field and the magnetic fieldThe controller that occurs a device connection, which is connected to the two visual detection devices, which is a visual detection device, a controller and a magnetic field.Magnetic field, with electricity droplets in the circular magnetic field, is moving to Xinlorezz. According to the detection results of the visual detection device, the control parameters of the control device change to the control of the control device in real time.Effective constraints are performed, and the droplets spread to the four weeks to reduce the flying angle of the droplet, thereby increasing the resolution of current dynamic printing.

Description

technical field [0001] The invention relates to the technical field of electrohydrodynamic printing, in particular to a control device for controlling the resolution of electrohydrodynamic printing, printing equipment and a control method. Background technique [0002] Inkjet printing technology has received extensive attention in micro-nano processing technology, such as flexible electronic circuits, wearable electronic devices, solar cells, biological functional devices, microfluidic chips, etc. The traditional inkjet printing method usually adopts the thermal bubble type and the piezoelectric type driving method. They all adopt the push driving principle. The line width of inkjet printing is generally 20-50um. As the size of the nozzle decreases, it takes More pressure, and solution viscosity makes nozzles more likely to clog. For thermal bubble inkjet printing, heating is required, but high temperature will affect the performance of the ink; for piezoelectric inkjet pri...
