SURFACE ELASTIC WAVE INKJET DEVICE USING A SECONDARY ELECTRODE FOR PRINTING INK ON A BOARD BY SPRAYING THE INK VAPORIZED BY USING SURFACE ELASTIC WAVES

摘要

PURPOSE: A surface elastic wave inkjet device using a secondary electrode is provided to form an additional electrostatic field using a secondary electrode in an electrostatic field by a primary electrode, thereby multiplying an amount of ink particles reaching to a board and an ink amount being printed on the board.;CONSTITUTION: A surface elastic wave inkjet device comprises a surface elastic wave head(10), a primarily electrode(20), a ground electrode(30), and secondary electrode. The surface elastic wave head supplies surface elastic waves to ink, thereby ionizing the ink. The primarily electrode is installed in one side of the surface elastic wave head. A first voltage for electrifying ink particles in which the ink is ionized is supplied to the primarily electrode. The ground electrode is installed in an opposite side of a printing surface of a board and generates electrostatic field in between the primarily electrode and ground electrode. The secondary electrode is installed in between the primarily electrode and board. A second voltage for generating a potential difference with the ground electrode is supplied to the secondary electrode.;COPYRIGHT KIPO 2013
