Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a prefabricated unit product in which the exterior material of the curtain wall that forms the outer wall of the building is a glass plate that is adhered and fixed directly to the metal frame or through a gasket. The present invention relates to a bonding device.

[Conventional technology]

Building construction is increasing the number of frameless curtain walls whose mounting frame materials are not exposed to the outside by using heat-reflecting glass plates on part or all of the outer walls for the purpose of aesthetic and energy effects on the appearance of the building. .

In this method, a metal mounting member is used to attach and fix a supporting frame for supporting the glass plate to the two edges or four peripheral edges of the upper and lower or left and right edges of the glass plate surface on the indoor side. It is known that a silicone sealing agent is used for adhesion to give flexibility.

Further, instead of a thick silicone sealant on the indoor glass plate surface, a band-shaped gasket, which is a molded elastic body, is adhesively fixed, and a metal holder is engaged in a mounting groove formed on the non-adhesive surface side of the gasket. A fitting member formed by combining the two is known (for example, Japanese Utility Model Publication No. 62-80981 and Japanese Utility Model Publication No.
62-49546).

[Problems to be solved by the invention]

In the production of the prefabricated exterior panel described above, in the former case, a backup material having a thickness is sandwiched between a glass plate and a mounting member, and a silicone sealing adhesive is filled in the gap with an injection gun to cure and cure. But
There are drawbacks such as poor adhesion due to the inclusion of bubbles generated during injection, cracking due to external stress from the bubble part of the cured adhesive, and time required for curing due to the adhesive having a thickness. A silicone sealing adhesive is applied on the surface, and the mounting member with a gasket is placed on top of the adhesive, and not only uniform adhesive force but also high finishing accuracy such as adhesion position, height, parallel, horizontal, etc. However, the conventional construction method, which requires the above-mentioned method, has a problem in that the accuracy cannot be achieved by such a conventional bonding means.

[Means for solving problems]

In order to solve the problems of the prior art, the present invention applies an adhesive to the edge of the masked glass surface on a table provided with a glass plate loading / unloading mechanism and a positioning and fixing mechanism, In a bonding device for a glass plate mounting member in which a mounting member is placed on top of an adhesive and fixed by adhesion, a pair of traveling frame bodies which can be moved back and forth along rails arranged on both upper ends of the table, and the traveling frame. Glass plate mounting having a nozzle that is movable left and right along a frame body and discharges the adhesive, and a holding member that holds the mounting member under the traveling frame body and controls the downward pressing by the pressing means The present invention provides a bonding device for bonding members.

[Action]

The holding member provided at the bottom of each traveling frame body holds the masked glass plate that holds the attachment member and carries it onto the table.

When the glass plate loaded on the table is fixed at a predetermined position, it moves along the rails to the position specified by each traveling frame body, and then the nozzle moves forward or backward along the side surface of the traveling frame body. Since the adhesive is discharged in the form of a strip only, there is no air entrapment, and the adhesive is applied on the edges of the masked glass.

Again, the traveling frame body moves along the rail, reaches the adhesive applied by the mounting member sandwiched by the holding member, and stops.

When the holding member that holds the mounting member descends onto the adhesive and presses the mounting member by the operation of the pressing means that is subsequently installed on the upper part of the traveling frame, even if there is adhesive or slight air bubbles It is extruded together with the adhesive protruding from both sides of the member to form a uniform adhesive film surface.

Also, by controlling the pressing force with a unique configuration even when the downward pressing is performed, deformation and destruction are prevented without giving an abnormal external force to the mounting member and the glass plate, and the thickness of the adhesive is adjusted. It is also possible to finish the glass plate surface to a specified height with high precision.

After that, the holding member rises by separating from the mounting member,
Wait for the next glass plate to be carried in by moving the traveling frame and sandwiching a new mounting member, but for the glass plate on the table, the curing and masking of the glass plate on the table are released by carrying out the next step. To move to.
