Fori recently supplied a highly flexible, automated robotic MIG welding assembly system. The system consisted of three similar lines that were able to accommodate nine different vehicle model variations.
The rear suspension cradle for the project satisfied approximately 90% of the vehicles in the family. There was a high level of importance on ensuring process control, the product had to be accurately controlled and monitored throughout each robotic weld line.
Each automated weld line possesses (21) MIG welding robots and (3) material handling robots. The current assembly system runs between 150 and 181 seconds depending on which model is being processed. After completion of the robotic welding, the critical component characteristics are machined with a pair of precision, custom machining centers.
The integration of the MIG welding and material handling robots has decreased cycle time and increased system throughput. Utilizing highly accurate machining stations and a repeatable process has also reduced waste and the quality of the final product has been increased.
The system resulted in the following benefits to the end user:
- Decrease in total cycle time
- Reduced infrastructure to handle product variations
- Increase in product quality
Main keys to success included the integrated robots, custom designed turn tables and the custom, precision machining centers.
