Challenge details:

Numerous dimensional inspections on fully assembled commercial vehicles are carried out before dispatch to ensure compliance with Vehicle pass off norms (VPN). These inspections include critical parameters such as wheelbase, overall vehicle length, front and rear overhangs, track width, etc. In addition, multiple vehicle variants are manufactured, each with unique dimensional and tolerance requirements. Currently, these measurements are performed using measuring tape, while certain complex parameters are verified using an optical 3D scanning system. This significantly impacts productivity as each vehicle inspection requires ~2-3 hours. Additionally, manual methods are susceptible to operator dependency, errors, and not repeatable.

We are seeking solution for automated, non-contact measurement of all critical vehicle dimensional parameters while the vehicle is moving on the assembly line conveyor. The desired solution should work within the existing production environment and complete all measurements within the vehicle assembly line takt time of approximately 4.5 minutes with vehicle assembly line conveyor speed of 3.5- 4m/min.
