Laser Guidance For Windshield Assembly Robot
The lasers establish a unique coordinate registration
based on each chassis position.
The Challenge:
Hummer chassis on the assembly line were not uniformly aligned as they entered the automated windshield installation work cell. In order for the robot to successfully perform its task, a unique coordinate registration on the windshield frame was required for each vehicle.
The Solution:
Newton engineers employed laser profilometry (the measurement and profiling of a 3D object) to track each Hummer chassis and guide the windshield installing robot. They developed a system using four lasers and cameras to provide individualized distance, rotation and angle data to the PLC as each vehicle moved through the work cell.
