Abstract

A fixture for supporting and masking an ecapsulated window assembly includes a generally planar floor having a periphery surrounded by generally upstanding walls. An upper edge of the walls engages an inner surface of a gasket formed on a periphery of the window assembly whereby the fixture masks the inside surfaces of the gasket and a glass sheet forming the window assembly. At least one aperture is formed in the fixture for receiving a reference pin utilized to locate the fixture with respect to a painting apparatus. A sensor is provided for generating a signal representing the engagement of the aperture by the reference pin and a control unit is responsive to the sensor signal for controlling a robot painting apparatus to spray paint an outer surface of the gasket. The fixture further is used to support the window assembly during curing of the paint and subsequent manufacturing operations.

Dependent claims

A method of supporting a window assembly for a gasket painting operation, the window assembly including at least one glass sheet having a predetermined portion thereof encapsulated by a gasket formed aroud the periphery of said glass sheet, the glass sheet and the gasket each having inner and outer surfaces, comprising the steps of:

(a) providing a floor;
(b) providing an upstanding continuous wall extending from said floor and having an upper edge defining a window assembly supporting surface, said floor and said wall defining a window assembly supporting fixture;
(c) forming at least one reference means in said fixture to locate same with respect to a predetermined gasket painting position;
and
(d) engaging an inner surface of a gasket formed on a periphery of a glass sheet of a window assembly with said upstanding wall upper edge whereby said fixture masks from a gasket painting operation an inner surface of the gasket and an inner surface of a glass sheet of the window assembly.
