ELECTROSTATIC COATING DEVICE, POWER SOURCE DEVICE FOR ELECTROSTATIC COATING DEVICE AND ELECTROSTATIC COATING METHOD

摘要

In the present invention, an electrostatic coating device is provided with the following: a nozzle part that discharges a liquid to a substrate; an opposite electrode that is disposed so as to face the nozzle part and that supports the substrate; and a power source device that applies voltage between the nozzle part and the opposite electrode. The electrostatic coating device is further provided with a shut-off circuit that selectively grounds the nozzle part. When the nozzle part is grounded by the shut-off circuit, the electric charge remaining in the nozzle part is transferred to the earth and such remaining electric charge vanishes. As a result, after the power source device is turned off, any dripping of the liquid from the nozzle part can be stopped more quickly.
