Abstract

The invention discloses a magnetic force controlled ink permeating type micro-contact printing device, wherein a magnet sensing layer, a sealing layer, a permeating layer, a supporting layer and a cylindrical ink groove are sequentially arranged on a pattern layer. A coil sleeve is arranged on the ink groove close to one end of the support layer, an electromagnetic flow valve and an air pressure communication pipe are arranged in an ink inlet pipe at the other end, a coil on the coil sleeve is connected with a coil circuit, an elastic seal is connected with the permeating layer through a magnetic field of the coil, and a controller is respectively connected with the electromagnetic flow valve, the coil circuit and the air pressure control unit. The magnetic force controlled ink permeating type micro-contact printing device integrally controls processes of seal installation, inking and printing in a micro-contact printing process, using the magnet sensing layer as an interlayer of the elastic seal, brings convenience to installation and processing of a large-area seal, can effectively control printing parameters, fully utilizes alcohol permeability of polydimethylsiloxane, and can perform inking continuously. The air pressure control unit controls the pressure of air in the ink groove and is matched with other printing processes to limit and adjust the speed of ink permeating.

Description

technical field

[0001] The invention relates to a printing device, in particular to a magnetically controlled ink permeable micro-contact printing device capable of forming micro-nano patterns on a specific substrate. Background technique

[0002] Microcontact printing technology is to contact the elastic stamp with micro-nano pattern on the surface with the surface of the substrate to form a patterned self-assembled monomolecular layer. It is different from other printing methods in that it uses a self-assembly system to form micropatterns of different materials. and microstructure.

[0003] The specific process of microcontact printing is to first use photolithography, electron beam etching, precision machining, etc. to form the required pattern on the surface of a silicon wafer to form a master plate for casting elastic stamps. Then polydimethylsiloxane is cast into the master plate, and after curing, it is peeled off to obtain an elastic stamp with micropatterns on the ...
