Advanced EOL Solution for Premium Segment Illuminated Door Panels: Maximizing Variability
In this project for door panels in the premium segment, the focus is on maximum variability. Four door panels each for three different model series, with additionally flexible features, must all be tested in just one EOL.
The solution: High-resolution camera on a robotic arm
This sophisticated testing setup is specifically designed to address the complexity of door panels with multiple light functions. Each panel requires thorough inspection from a multitude of positions and angles, necessitating a versatile and precise testing system. To achieve this, we utilize a high-resolution industrial camera attached to a robotic arm, positioned at the bottom of the End-Of-Line (EOL) testing setup. This allows for detailed and dynamic inspection of the A-side light functions. Furthermore, due to the manual connection of LED modules, the door panels are placed B-side up in the EOL. To comprehensively capture the B-side, we have equipped the test stand with multiple stationary cameras on the ceiling. This dual-camera system enables us to meticulously examine both sides of the door panel, focusing on the intricate light functions on the A-side and the precise control of attachments on the B-side. This innovative approach ensures a thorough and accurate assessment of the door panels, reflecting our commitment to excellence in testing for the premium automotive segment.
During the test, the robot moves to various positions and the light functions are recorded separately. To save cycle time, photos from the stationary cameras are taken while the robot moves to the next position.
A total of 6 interchangeable frames allow all 12 door panel models to be tested in the same facility. Overall, the testing facility manages over 1000 test criteria!
