BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a plate member with a molding, and more particularly to a method for manufacturing a glass window with a molding in which a resin molding is integrally molded on the periphery of a glass plate.

2. Description of the Related Art A glass window with a molding in which a synthetic resin molding is integrally molded on the periphery of a glass plate is commonly called a module assembly window (hereinafter referred to as MAW), and the number of steps for assembling the vehicle body can be reduced. Taking advantage of this feature, it is used in many ways. This MAW is manufactured by applying an adhesive or a primer (hereinafter collectively referred to as an adhesive) to the peripheral part of the window glass plate, and then integrally molding a resin molding on the part to which the adhesive is applied. ..

The MAW adhesive application range is naturally limited because the molding margin of the window glass plate to which the adhesive is applied is a limited width from the end of the glass plate. When the adhesive coating width is constant, it is common to apply the adhesive by manually contacting the glass plate with a brush for coating. Also, when applying adhesive to a large area flat or curved glass plate such as the rear or front, attach a brush to the robot tip and make contact with the glass plate, and teach the robot along the application trajectory. As a result, the adhesive could be applied with a constant width.

[0004]

In recent years, by taking advantage of the large degree of freedom in designing a molding of a MAW, the number of complicated moldings having different adhesive coating widths on the same side has increased. However, with the complicated molding shape as described above, a conventional method of applying an adhesive with a constant width to a complicated application pattern in which the application width changes midway or gradually changes. Is to apply the application surface to the plate-like object and apply along the application trajectory,
It has a drawback that the robot speed is limited and the coating tact becomes long.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to newly provide a method of manufacturing a plate member with a molding, which has not been known in the past. Is.

FIG. 1 is a perspective view illustrating a method of applying an adhesive when manufacturing a plate with a molding of the present invention, in which an application gun 8 as an application jig is attached to the tip of an adhesive application robot 1. An adhesive layer 4 is provided on the plate-shaped body 3 so that the plate-shaped body 3 and the coating gun 8 do not come into contact with each other.

In particular, for the application of a complicated pattern such as the application locus 5, a solenoid valve (not shown) controls the ON / OFF of the discharge from the application gun 8, and the area where the adhesive is applied and the area where the adhesive is not applied. Can be provided, and the coating width can be changed and the limited portion can be continuously coated by intermittent coating in a series of movements of the coating gun 8 around the plate-shaped body 3.

Here, the MAW product in the present invention means
The plate-shaped body and the molding are integrally molded.The steps include degreasing the plate-shaped body, applying an adhesive for bonding the molding, drying and preheating the plate-shaped body. Set in a mold and injection mold synthetic resin for molding, or reaction injection molding of synthetic resin raw material (RIM method)
Alternatively, a method of extruding a synthetic resin by setting the plate-shaped body on a fixing jig is used.

The plate-like body of the present invention may be a flat plate-like one or a curved one, and its material is a glass plate, laminated glass, tempered glass, double-layered glass, synthetic resin. A plate made of, or a laminated plate obtained by combining these is used, and a plate using a glass plate is particularly preferable. As the synthetic resin, so-called organic transparent materials such as polycarbonates, polystyrenes and polymethylmethacrylates can be used, and at least 2
A laminate of two or more sheets can also be used.

The molding is a general term for gaskets, moldings, weather strips, seal rubbers, etc. formed around the plate-like body, and may be provided all around the plate-like body, or It may be interrupted in the middle of the entire circumference, or may be provided on one side or several sides of the plate-shaped body. Although soft polyvinyl chloride is generally used as the molding material, polyolefin-based elastomers, polyurethane-based elastomers, polyester-based elastomers, elastomers such as polyamide-based elastomers, polyurethanes, ethylene-vinyl acetate copolymers, vinyl acetate, chlorinated polyethylene, Ethylene propylene diene terpolymer (E
PDM) or other rubber material may be used. Further, a mixture of two or more of these materials may be used if necessary.

As the adhesive, polyurethane, polyester, polyamide, phenol, acrylic,
It is at least one kind or a mixture of two or more kinds such as epoxy type, cyanoacrylate type and rubber type, and may be used as it is, may be dissolved in a solvent, or may be used as a so-called emulsion dispersed in water. ..

The adhesive application jig used in the present invention may be used without contacting the plate-like body and may be of a type that sprays an adhesive or a type that drops the adhesive, but the former type is more preferred. As the spray type coating jig, a coating gun for coating and a coating gun for select coat system are more preferable. Select coat system is solenoid valve ON / O
Since the ON / OFF of the adhesive discharge is controlled by receiving the FF signal, the application width can be changed and the application of only a limited portion by intermittent application can be sufficiently dealt with. The type of robot used in the present invention is not particularly limited, but a 6-axis robot or the like is preferable in order to accurately realize a complicated coating pattern.
