Abstract: An electrostatic coating device comprising a nozzle section that discharges a liquid to a substrate, a counter electrode that is disposed in such a way as to face the nozzle section and supports the substrate and a power source device that applies a voltage between the nozzle section and the counter electrode further comprises an instantaneous stop circuit that selectively grounds the nozzle section. When the nozzle section is grounded by the instantaneous stop circuit, a charge remaining in the nozzle section goes to the ground and the charge remaining in the nozzle section disappears. For this reason, after the power source device is turned off, dripping of the liquid from the nozzle section can be completed as quickly as possible.
Abstract translation: 一种静电涂布装置，其特征在于，具备将液体排出到基板的喷嘴部，与所述喷嘴部对置配置并支撑所述基板的对置电极，以及在所述喷嘴部与所述喷嘴部之间施加电压的电源装置 对电极还包括选择性地接地喷嘴部分的瞬时停止电路。 当喷嘴部分通过瞬时停止回路接地时，喷嘴部分中剩余的电量进入地面，并且喷嘴部分残留的电荷消失。 因此，在关闭电源装置之后，可以尽可能快地完成液体从喷嘴部的滴落。
