This invention relates to a dam bonding device for a windshield glass of a vehicle, which has a head equipped with a press roller and an abutting roller, and has a head equipped with a press roller and an abutting roller. A holder block having a drive device is disposed so as to be able to freely traverse the windshield glass so as to cover the windshield glass with respect to a guide provided along the holder block. A roller provided in contact with the end surface of the windshield glass detects the displacement of the head along the periphery of the windshield glass and controls horizontal and vertical traverses so that the head can move in a fixed position, and the head can also rotate. In addition, the invention relates to a dam bonding device for a windshield glass of a vehicle, which detects a windshield glass corner portion and causes a head to revolve around a set radius.

<Prior art> As is well known, in vehicles such as automobiles, there is a part where a windshield glass is fixedly attached to the window, and usually an elastic strip made of rubber or the like is attached to the inner outer peripheral edge of the windshield glass. A dam is attached around the circumference, and an adhesive is attached to the outside of the dam to prevent leakage of the adhesive and inflow of precipitation.

Then, the contact roller 8 is made to trace and roll along the end surface of the windshield glass 7 set on a predetermined support base, and the dam 10 that is fed out to the dam holder 9 is pressed against the windshield glass 7 by the press roller 12 via the dam guide 11. Glue to the edges and apply release material 1
3, a bonding device has been devised in which the adhesive is wound around a take-up roller 14.

<Effects of the Invention> As described above, according to the invention of this application, in the dam bonding device for the peripheral edge of the windshield glass of a vehicle, the head has a roller for contacting the end surface of the windshield glass and a dam pressing roller for the edge. By doing this, an excellent effect can be achieved in that the head basically follows along the periphery of the windshield glass and presses down the dam for bonding.

Thus, a guide is provided along one side of the table to allow the holder block to move, and the holder block is provided with another guide to allow the head to move and pivot. The head has the effect of being able to freely follow the circumference of the windshield glass vertically, horizontally, and around the corners.

In addition, the supporting bracket, which is brought into contact with the head by means of an abutting roller, is supported by the head via a three-dimensional bearing, which allows it to absorb the unevenness of the glass surface to the revolving head without causing any problems. There is also the effect that the dam can be held in contact with the dam.

Furthermore, the support bracket is equipped with a displacement detection device for the head, which is connected to the vertical, horizontal, and turning displacement devices, so that the tracking of the head to the end surface of the windshield glass during driving can be automatically corrected to accurately set the posture. This provides an excellent effect in that it can be adhered at a precise distance from the dam end face all around the dam.

Therefore, regardless of the type of windshield glass, the dam can be bonded to all types of windshield glass with one device.

By providing a windshield glass corner detection device such as an air sensor on the support bracket and connecting it to a separating device for a roller that contacts the end surface, the corner portion can be detected regardless of the type of windshield glass, for example. Even if the corner portion is formed with an extremely small radius, the dam can be rotated and bonded with a constant radius, and there is an advantage that the bonding work will not be hindered.
