Application: Attach multiple components to an HVAC blower assembly
Solution: Cartesian robots equipped with blow-fed screwdriver spindle
Chassis: Three rotary index dial tables linked in series
Flexible Automation utilized three rotary index dial tables to transfer a blower housing through the assembly process. Each dial table had four stations with fixtures that would hold the product in different attitudes on each dial table. Components were manually placed onto the housing before being indexed to the automated screwdriving stations. Four Cartesian robots were equipped with blow-fed automatic screwdriver spindles to secure the various components. Two six-axis robots were used to reorientate and transfer the product between the three rotary dial tables. Throughout the process, barcode scanners, vision sensors, and laser displacement sensors were used to poka-yoke the various component combinations.
