Optimum Windshield Sealing

optimum windshield sealing Peaks windshield and rear window glass tooling system establishes the correct robot-applied forces to achieve precise urethane sealing. The force data is then used to program the robot for the production environment.

The ultimate purpose of Peak's glass sealing system is to establish the correct installation forces and time necessary to achieve proper and consistent windshield and rear window sealing. Optimum windshield and rear window sealing helps eliminate wind and road noise, enhancing customer comfort.

In a simultaneous engineering program, Peak applied CATIA-based data to define vehicle body geometry and utilized its own proprietary 3D CAD modeling design technology.

The glass sealing tooling consists of a lightweight fabricated frame that fits over the windshield or rear window and is positioned accurately on four rest points -- one on each fender and two on the roof. Two clamps hold the frame to the body.

Eight air cylinders are mounted on the frame perpendicular to the windshield and rear window surfaces. These cylinders simulate the eight suction cup pressure points that will be used in the robot's end-of-arm production tooling. Each cylinder can be adjusted individually. A load cell on each cylinder measures the force applied to the glass.

The load cells are integrated into a digital readout system which informs the operator of force being applied at each point. In addition to the load cell measurements, indicators are positioned at key locations around the glass surfaces which measure the springback of the glass, after pressure is released from the cylinders. The wet-out of the urethane is also measured and the forces are adjusted for uniformity.

Peak Industries has been a supplier of custom automation and assembly components and special machines and systems for the automotive and other manufacturing industries since 1966.
