Abstract

The invention discloses a method for forming multi-layer liquid droplet wrapping. The method comprises the following steps: respectively putting multiple mediums into micro channels correspondingly, and adjusting the distance between the outlet of each micro channel and a first surface of a glass substrate; driving the glass substrate to move in a preset direction; conveying the mediums towards the first surface, and smearing the mediums on the first surface to form a medium layer; when the glass substrate is moved to a preset position, and at a preset moment, supplying a vertical incident laser beam towards a second surface of the glass substrate from a preset incidence position till the laser beam pushes the medium layer close to the first surface to be sequentially embedded into other medium layers and ejected into the air to form multi-layer liquid droplet wrapping, wherein the first surface and the second surface are planes parallel to each other. By adopting the method, precise control on single multi-layer liquid droplet wrapping can be achieved, continuous formation of the multi-layer liquid droplet wrapping can be conveniently achieved, relatively good applicability is achieved, the production efficiency of the multi-layer liquid droplet wrapping is high, and the production cost is low.
