  • Patent number: 6245173
    Abstract: A window glass of a vehicle, to which a hot melt adhesive agent is applied, is pushed while the window glass is held by a jig which is mounted on a robot. An allowable range of temperature of the adhesive agent is set between an upper limit and a lower limit. The upper limit is one at which the adhesive agent comes to have such a holding force above a predetermined value as to prevent deviation of the window glass. The lower limit is one at which a compression reaction force when a bead of the adhesive agent applied to the window glass is crushed to a predetermined thickness becomes smaller than a predetermined value. The adhesive agent is applied to the window glass at such a temperature that the temperature thereof at the time of completion of pushing of the window glass falls within the allowable range. The apparatus for mounting the window glass has a jig for the window glass which is provided at a front end of a robot arm.
