Problems solved by technology

[0003] The existing micro-droplet printing platform is designed and planned for the items required for micro-droplet printing, including a movable substrate platform, a printing head module, a printing head maintenance module, an image observation module, and a printing control module. It is composed of units, but it often encounters the problems of print head clogging and air bubbles, which cannot effectively solve the problem of poor printing
Furthermore, after the micro-droplet printing is completed, when performing maintenance work on the printing head module, it is impossible to observe the substrate image in real time, and it is impossible to confirm the printing quality in real time
Causes delays in output time, if there is a demand for different micro-droplet printing methods, it cannot provide an appropriate way to solve the problems that occur in different substrates and micro-droplets in the method

Abstract

The invention discloses a micro-drop spattering device and method, which comprises the following parts: spatter mode, mobile platform mode, image detecting mode, temperature control mode and spatter head maintaining mode, wherein the spatter head maintaining mode cleans spatter head; the spatter base carries the mobile platform mode, which detects the relative position and angle of spatter head and base; the temperature control mode modulates the surface temperature of base, which makes the temperature of base and micro-drop evenly, which improves flatness of moulded spatter film.

Description

technical field [0001] The present invention relates to a micro-droplet printing device and method, in particular to a micro-droplet printing device and method applied to micro-component coating. Background technique [0002] Controllable Drop-on-Demand Ink Jet Printing (Drop-on-Demand Ink Jet Printing) technology is a fine and highly reproducible coating method, which uses the jet printing head to perform micro-droplet printing on the printing target. It can be applied to the precise circuit printing and forming of various printed circuit boards and circuit substrates. Generally, the printing head is used to move back and forth in the X-axis direction, and the printing mark can be moved forward in the Y-axis direction to jointly achieve the purpose of micro-droplet printing. Due to the wide range of uses of micro-droplet printing, it is widely used in printed circuits. Board (Printed CircuitBoard, PCB), color filter (Color Filter, CF), organic thin film transistor (Organic...
