Product Specifications

Technical details and manufacturing context for Automated Fastening System

Definition
The Automated Fastening System is a component of the Automotive Modular Chassis Assembly System, designed to precisely position and install various fasteners to join chassis components. It integrates robotic arms with specialized end-effectors that pick fasteners from feeders, position them at predetermined locations, and apply controlled torque or force to secure connections according to programmed specifications. The system ensures consistent torque, reduces manual labor, and maintains assembly quality standards throughout the production line.

Key technical parameters include a rated torque range of 5–200 N·m covering M6 to M16 fasteners, with torque accuracy of ±3% for safety-critical joints per ISO 5393. Cycle time per fastener is 2–5 seconds, including tool change and positioning. Fastener diameter range is 4–16 mm for bolts, screws, and rivets, with length capacity of 10–80 mm. Positioning repeatability is ±0.1 mm per ISO 9283, ensuring consistent joint alignment. The articulated robot arm has 6 axes, with a maximum reach of 1500–2500 mm depending on chassis size. Payload capacity is 10–50 kg, including tool and fastener feeder. Operating temperature range is 0–45 °C for control cabinet and robot. Ingress protection rating is IP54–IP65 per IEC 60529. Supply voltage is 380–480 V AC, three-phase, 50/60 Hz per IEC 60038. Power consumption peaks at 5–15 kW during fastening cycle. Total weight of robot and control cabinet is 500–1500 kg.

Materials on file include steel, aluminum alloy, and industrial-grade plastics. These values are directory reference ranges and must be confirmed for the actual model and application with the legal manufacturer or supplier. Standards listed are procurement references, not proof of certification or compliance.
Working Principle
The system uses robotic arms equipped with specialized end-effectors to pick fasteners from feeders, position them at predetermined locations on chassis components, and apply controlled torque or force to secure connections according to programmed specifications. The end-effectors may include screwdrivers, nutrunners, or riveting tools, depending on fastener type. The control system coordinates robot motion, fastener feeding, and torque application to achieve consistent joint quality. Sensors provide feedback for positioning and torque verification, enabling closed-loop control. The system is integrated into the assembly line, with cycle times optimized for production throughput.
