Successful screwdriving requires the right combination of product fixturing, screw presentation, and driving technology. Whether your manufacturing plan includes semi-automated lean stations or a fully automated manufacturing system, ATS has extensive experience in designing, building, and integrating complete screwdriving systems.
Components to be fastened together must be fixtured securely in the correct orientation relative to on another. Fixtures play a pivotal role in delivering success with screwdriving, and ATS designers pay special attention to produce robust fixture designs.
The approach to screw feeding hinges on your overall manufacturing plan, and quality control requirements.
For semi-automated stations, screw pick bins combined with manual screw presentation by the operator is often adequate, but susceptible to operator variability.
For fully automated manufacturing, blow fed screw feeding systems combined with driver yokes allows for screw presentation while permitting the screwdriver to follow the screw to a fully driven position.
Pneumatic or electric screwdriver selection depends on your screw driving requirements (e.g., driven torque, screw size, production speed). Electric screwdriving offers the greatest control, where both torque and angle are monitored against a known good part signature. ATS has experience with both styles of screwdrivers and numerous industry leading screwdriver manufacturers.
