When the glass is sequentially moved from (a) to (e) and rotated once, the adhesive is uniformly applied to the entire circumferential surface, and the adhesive application work to the front windshield IIJ is completed.

Thereafter, when the lock release cylinder 27 is activated to release the vacuum cover >10 from the window mounting jig 9, the operator holds the window mounting jig 9 and fixes the front window glass 11. The work is carried out to transport the windshield to the window assembly workshop. Then, each time a subsequent windshield is placed on the turntable device 2, the same operation as described above is repeated, and the predetermined adhesive application work according to the specifications of each windshield is performed. This will be done twice. At that time, due to the accuracy possessed by the industrial robot 23, the adhesive application work can be performed automatically and accurately without applying the adhesive to the glass surface or damaging the front windshield. . Also,
Since the turntable device 2 is equipped with the function of performing linear motion in the X and Y directions, the movement of the industrial robot 23 is simplified, making it possible to perform adhesive application work in a short time. It is possible to improve efficiency.

In the above embodiment, the turntable device 2 is provided with the linear movement function in the X and Y directions relative to the front windshield 11, but the industrial robot 23 may also be provided with the linear movement function in the X and Y directions. Of course. In this case, the rotational movement range of the front window glass 11 becomes narrower, making it possible to perform coating work in a narrower range, and also increasing work safety for those working in the R area by constantly rotating the glass. It is possible to prevent a decrease in work efficiency.

Further, in the above embodiment, an automatic adhesive application device for a front windshield was described, but it goes without saying that the present invention can be similarly applied to various other windshields such as a rear windshield.

As explained above, according to the present invention, an industrial robot can automatically and accurately apply adhesive to various types of windshield glass having different specifications for each vehicle. Therefore, it can greatly contribute to the automation and labor saving of the adhesive application work for window glasses.
