Abstract

In a manufacturing method for a glass panel with a gasket, an elastic member is placed on a table, and a multilayer glass panel is placed thereupon. A die is pressed against a top surface of the multilayer glass panel, thereby compressing the elastic member and glazing gasket molding material together with adhesive ejected from the application nozzle and applied to the top surface of the multilayer glass panel.

Claims

1. A manufacturing method for a glass panel with a glazing gasket for ejecting glazing gasket molding material together with adhesive from an application nozzle onto a periphery of a top surface of the glass panel that is facing upwards and placed on a table, the glass panel and the application nozzle being moved relative to one another to apply the glazing gasket molding material, the method comprising:

placing an elastic member on the table, the elastic member being made from an elastically deformable material;

placing the glass panel on the elastic member;

detachably attaching a fixture plate to a portion of the periphery of the top surface of the glass panel, so that the fixture plate is immoveable relative to the glass panel;

applying the glazing gasket molding material to the top surface of the glass panel by ejecting the glazing gasket together with the adhesive slanting downward from an outlet to the rear in a direction of movement of the application nozzle, while a portion of the application nozzle in which the outlet is formed is pressed against the top surface of the glass panel to compress the elastic member;

cutting portions on the fixture plate that include the application starting point and the application finishing point with a laser, and removing the portions that include the application starting point and the application finishing point together with the fixture plate from the surface of the glass panel;

bonding a glazing gasket molding body with adhesive to a portion on the top surface of the glass panel where the portions that include the application starting point and the application finishing point have been removed, the glazing gasket molding body having a same cross-sectional shape as the glazing gasket molding material applied to the top surface of the glass panel; and

dividing the adhesive vertically by a partition wall such that a lower layer of adhesive is applied to the glass panel and an upper layer is applied to the glazing gasket molding material, and the lower layer and the upper layer of the adhesive are brought into contact by a termination of the partition wall.

2. A manufacturing method for a glass panel with a glazing gasket for ejecting glazing gasket molding material together with adhesive from an application nozzle onto a periphery of a top surface of the glass panel that is facing upwards and placed on a table, the glass panel and the application nozzle being moved relative to one another to apply the glazing gasket molding material, the method comprising:

placing an elastic member on the table, the elastic member being made from an elastically deformable material;

placing the glass panel on the elastic member;

detachably attaching a fixture plate to a portion of the periphery of the top surface of the glass panel, so that the fixture plate is immoveable relative to the glass panel;

performing a first application step, by applying the glazing gasket molding material to the fixture plate, starting at an application starting point located on the fixture plate, by ejecting the glazing gasket molding material together with the adhesive slanting downward from an outlet to the rear in a direction of movement of the application nozzle, while a portion of the application nozzle in which the outlet is formed is pressed against the fixture plate to compress the elastic member via the glass panel;

applying the glazing gasket molding material to the top surface of the glass panel in a second application step by ejecting the glazing gasket together with the adhesive slanting downward from an outlet to the rear in a direction of movement of the application nozzle, while a portion of the application nozzle in which the outlet is formed is pressed against the top surface of the glass panel to compress the elastic member;

performing a third application step, out from the top surface of the glass panel, by applying the glazing gasket molding material to the fixture plate, by ejecting the glazing gasket molding material together with the adhesive slanting downward from an outlet to the rear in a direction of movement of the application nozzle, and finishing application at an application finishing point located on the fixture plate, while the portion of the application nozzle is pressed against the fixture plate to compress the elastic member via the glass panel;

cutting portions on the fixture plate that include the application starting point and the application finishing point with a laser, and removing the portions that include the application starting point and the application finishing point together with the fixture plate from the surface of the glass panel; and

bonding a glazing gasket molding body with adhesive to a portion on the top surface of the glass panel where the portions that include the application starting point and the application finishing point have been removed, the glazing gasket molding body having a same cross-sectional shape as the glazing gasket molding material applied to the top surface of the glass panel;

wherein, in the first, second and third application steps, the glazing gasket molding material and the adhesive are applied while keeping the application nozzle above the top surface of the glass plate vertically unchanged.
