Screwing and Fastening

Robotic screwdriving makes it easy to do quick changeovers and run small, varying size batches of related assemblies. Robots can drive screws from all directions, sometimes with varying torque requirements. They also have the ability to drive different sizes of screws using various feeders for each type of fastener.

However, with robots, the accuracy of the parts location and stack-up become a critical variable. Typically, the robot is going to go to the exact same location every cycle. If the parts are fixtured correctly and the tolerance of the stack-up is uniform with respect to design, then the result is going to be a very reliable production system.
