Robotic Screwdriving for Assembly Processes

GLOBAL builds screwdriving cells around the fastening strategy each joint requires, using controlled screwdriving or nut-running tools that apply the target torque and can add angle monitoring for critical fasteners. Each fastening event can capture torque, angle, depth, and pass/fail results, and the tool and feed method are selected for the fastener type and access. The cell can confirm the fastener seated correctly before the part advances, and screwdriving can be combined with press-fit, insertion, pick-and-place, or dispensing where a build needs more than fastening.

GLOBAL engineers and supplies the screw feeding, fixturing, and part presentation as part of the cell so both the fastener and the part arrive in a repeatable position. Screws can be delivered by automatic feed to the tool, and parts can be presented in fixtures, nests, trays, or on conveyors, or located with vision, depending on geometry and volume. Feed and nest design are worked out from your part samples, fastener specifications, and drawings.

Yes. When the part family and fasteners are known up front, the cell can be built for quick changeover using selectable programs, quick-change bits or tooling, adjustable fixtures, and feeding sized for the fastener range. Vision can locate parts that vary in orientation so one cell covers more part numbers with less dedicated fixturing. Part mix, fastener types, and changeover frequency are reviewed during design.

GLOBAL works from your takt-time target and lays out the cell to meet it, balancing robot travel between joints, fastening dwell, screw feed, and part presentation so the operations overlap. For high fastener counts, work can be split across stations or additional robots, or multiple spindles considered. Expected throughput is confirmed in simulation before build so the cell holds your production rate.

Fastening cells are designed with poka-yoke checks such as part-present and orientation sensing, fastener counting, and torque and angle monitoring so a missed, cross-threaded, or out-of-spec fastener is caught before the part advances. The system can record torque, angle, depth, and pass/fail results with serial numbers and process parameters to build a documented history for each unit. GLOBAL configures the data collection around your quality and traceability requirements.

Before shipment, GLOBAL runs the cell through factory acceptance and a run-off on your parts and fasteners to confirm cycle time, torque and angle results, and quality checks. Reach, feeding, tooling, and part flow are proven out, and the cell is validated against the agreed production and quality requirements during on-site commissioning. This staged run-off reduces surprises at launch.

After commissioning, GLOBAL trains operators and maintenance staff on running the cell, loading programs, clearing faults, and routine care such as bit and feeder maintenance, and can recommend spares covering bits, tooling, sensors, and wear items. Ongoing support is available for troubleshooting and for adding parts or fasteners later. Because GLOBAL also provides automation staffing, additional engineering resources can be arranged as needs grow.
