Title:
MASKING JIG
Document Type and Number:
WIPO Patent Application WO/2019/221100
Kind Code:
A1
Abstract:
Provided is a masking jig which is used in an electrostatic spray device that sprays an atomized liquid onto an coating object by applying a voltage between a liquid spraying part and a heteropolar part. The masking jig comprises a masking body formed of an insulating material and an outer peripheral conductor body formed of a conductor material or a semiconductor material. The masking body is formed to have one or more apertures for defining a coating section on an object to be coated. The outer peripheral conductor body extends in the normal direction of a plane identical to or contiguous with a plane in which the aperture of the masking body exists and is provided outside around the axis passing through the center of gravity of the aperture and is provided closer to the liquid spraying part than the masking body is. The heteropolar part is made to have the same potential direction as an object to be coated relative to the liquid spraying part.
