ELECTROSTATIC INK-JET HEAD

摘要

PURPOSE: An electrostatic force inkjet head is provided to form a uniform electrostatic field on a substrate with a peripheral electrode structure being installed around a capillary tube head and to obtain the structural stability of an electrostatic force inkjet head with a coupling structure of a bolt shape of the capillary tube head and the peripheral electrode. CONSTITUTION: An electrostatic force inkjet head comprises a holder plate(110), a capillary tube head(120), a backside electrode, a voltage applying unit, and a plurality of peripheral electrodes(130). The holder plate is arranged in the upper side of the substrate. The capillary tube head is installed in the holder plate and comprises the capillary tube. The backside electrode is arranged in the rear side of the substrate. The voltage applying unit applies voltages to the capillary tube head and backside electrode so that an electrostatic field is formed in between the capillary tube head and backside electrode. The peripheral electrode is installed in the holder plate to be arranged in the peripheral of the capillary tube head and form the uniform electrostatic field on the substrate by being connected to the voltage applying unit.
