Collaborative Fastening

Safe, Efficient Fastening

Yaskawa combines advanced nut driving and tightening technology with collaborative robotic automation, enabling manufacturers to improve productivity while maintaining a safe and ergonomic work environment. Collaborative applications allow operators and robots to work within shared spaces, supporting flexible assembly processes and efficient human-machine interaction.

Unlike traditional automation that relies on physical separation, a collaborative fastening cell is designed around the safety of the entire application, including the robot, tooling, workspace, operator interaction, and risk reduction measures. This approach enables manufacturers to achieve both operational efficiency and workplace safety.

Collaborative Fastening Automation is designed to:

Rapidly engage and drive nuts onto threaded fasteners
Provide precision screw tightening
Deliver repeatable tightening performance
Reduce assembly cycle times
Minimize operator fatigue
Support flexible, mixed-model production environments

Automation helps manufacturers increase throughput by taking over repetitive fastening tasks while ensuring consistent assembly quality from part to part.

Collaborative Safety Through Power and Force Limiting (PFL) Capability

A key advantage of the HC-Series Collaborative robot platform is its Power and Force Limiting (PFL) capability. PFL technology helps enable safe operation in collaborative applications by continuously monitoring forces generated during robot motion.

Sensors in Every Joint

Integrated force sensors continuously compare detected forces against predefined safety thresholds. When force levels exceed programmed limits, the system can take corrective action such as stopping motion or moving away from the detected contact.

Avoidance Function

The robot can safely respond to unexpected contact during operation. If touched, the robot can be gently pushed away, allowing interaction without damage or injury concerns. After a defined pause, the robot can automatically resume its programmed fastening sequence.

Multi-Stage Unclamp and Release

Advanced safety functions help meet or exceed the requirements of ISO/TS 15066 collaborative robotics guidelines, enabling safe recovery and restart procedures during operation.

Collaborative Robot Design

Rounded edges, pinch-resistant construction, and impact-dissipating features help reduce injury risks while enhancing operator confidence when working alongside automation.

Built to Collaborate

Ideal for Shared Workspaces

In many fastening applications, operators may load components, perform inspections, or complete adjacent assembly tasks while the robot handles repetitive nut driving and tightening operations. Collaborative automation supports this shared-workspace approach, allowing manufacturers to optimize both human expertise and robotic precision.

Benefits of Collaborative Fastening Automation

Improved assembly productivity
Consistent fastening quality
Enhanced worker safety
Reduced ergonomic strain
Flexible deployment in existing production lines
Simplified operator interaction through hand-guided teaching
Faster return on automation investment

Bring Collaborative Fastening to Your Production Line

Fastening technology paired with Yaskawa's HC-Series Collaborative robots delivers a powerful combination of safe human-robot interaction, Power and Force Limiting technology, and precision nut driving performance. The result is an intelligent fastening solution that enables manufacturers to increase efficiency, improve quality, and create safer production environments.

Technology Partners

Improve Fastening Quality with Intelligent Position Verification

The Sanyo Machine Vision Nutrunner System (SMVS) helps manufacturers eliminate fastening errors by ensuring the tool is in the correct position before a tightening cycle can begin. Using an integrated vision system, the solution verifies the tool's location and orientation in real time, allowing fastening only when the nutrunner is within the designated target position and angle.

Collaborative Tightening Automation with ESTIC and Yaskawa

Manufacturers can automate precision fastening applications with a compact, flexible solution by combining ESTIC's advanced tightening End-of-Arm Tooling (EOAT) with Yaskawa Collaborative robots. This integrated solution delivers intelligent nutrunner technology for applications ranging from light assembly to high-torque fastening, while enabling safe operation in shared workspaces and providing advanced quality control and traceability.
