Automatic Screwdriver for Ergonomic Relief in High Torque Joining

Application Spotlight

Faced with the need to increase throughput on already strained operators, an office chair manufacturer turned to Visumatic to jump start productivity. The stamped metal components required manual manipulation to align with the mating seat base, so full automation was immediately off the table.

This fairly-high torque operation for handheld assembly required that a 1/4-20 x 1” long hex head bolt with a molded washer be automatically fed and driven to the required 140 in/lbs torque to attach a seat control assembly in 4 locations. Visumatic worked with their manufacturing engineer to fully understand the assembly line work area and the demanding component placement conditions.

The VSC-900 automatic feed screwdriver was chosen so the operator need only position the tooling tip and push down to start the cycle. Ergonomics were improved by implementing an overhead balancer to support the tooling and a biomechanical forearm support to spread out the torque reaction force, relieving wrist joint strain.

The system’s straightforward design allowed for rapid deployment on the line, making it simple to train new operators. With the machine handling the screw, the operator was able to work more comfortably and much faster.
