Printing device and printing method

Abstract

The invention provides a printing device and a printing method, and relates to the technical field of plane printing. The printing device includes a coating mechanism and a printing mechanism; the coating mechanism includes a coating roller, an ink distribution roller and an ink shifting roller, and the ink distribution roller and the ink shifting roller respectively act on the coating roller; wherein the adhesive force relationships between the coating roller, the ink distribution roller or the ink shifting roller and the liquid metal satisfy the following relationship that: the ink shiftingroller is smaller than or equal to the coating roller and larger than the ink distribution roller, or the ink shifting roller is smaller than the coating roller and greater than or equal to the ink distribution roller. The invention provides the printing device. According to the printing device, the maximum amount of the liquid metal can be attached to the coating roller, the ink shifting roller can drive the liquid metal to be distributed along the axial direction of the coating roller, and the liquid metal attached to the coating roller can be leveled through the distribution roller; and therefore, the requirements of liquid metal printing can be met.

Description

technical field

[0001] The invention belongs to the technical field of planar printing, and in particular relates to a printing device and a printing method. Background technique

[0002] Liquid metals generally refer to low-melting-point metals that are fluid at room temperature. Due to their fluid and good conductor properties, they can be printed, printed, sprayed, etc. to realize the production of flexible electronics, planar electronics and other products.

[0003] Although liquid metal has the above-mentioned advantages, it has a very high selectivity for adhesion materials, and cannot be well applied to any printing equipment currently on the market. Contents of the invention

[0004] In view of this, an object of the present invention is to propose a printing device to solve the problem of lack of equipment for printing liquid metal in the prior art.

[0005] In some illustrative embodiments, the printing equipment includes: a coating mechanism and a printing mech...
