Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for assembling a sheet member for closing an opening of a work.

[0002]

2. Description of the Related Art Generally, in a vehicle body shell or side door as a work to which a seat member is assembled, a plurality of openings are formed in an inner panel for welding work and parts assembly work. A plurality of openings for reducing the weight are formed, and the plurality of openings are closed by a sheet-shaped seat member assembled at a seat assembly station in the middle of the automobile assembly line. In the sheet assembling station, a sheet member corresponding to the shape of the opening to be closed is selected from among a plurality of sheet members having different shapes prepared in advance, and the release paper on the back side of the sheet member is peeled off to remove the sheet member. Is manually attached to the inner panel at a predetermined position to close the opening.

On the other hand, in order to automate the work of assembling the sheet member to the side door, for example, 63-180.
In Japanese Patent No. 519, a sheet member is set with the back surface facing upward on a positioning jig supported in a horizontal position, adhesive is applied to the back surface of the sheet member, and then the positioning jig is rotated in a vertical position. There is described a method of assembling a seat member for a side door, in which the seat member is pressed against a predetermined position of the inner panel of the side door to assemble the seat member to the side door.
