The medical device industry demands exceptional precision, consistency, and reliability—standards that traditional manual assembly methods often struggle to meet due to low efficiency and high variability. In response, Han’s Laser has developed the KV-Axis Automated Assembly Workstation, a key solution for achieving full automation and high precision in medical device production lines.

System Overview

The KV-Axis Automated Assembly Workstation is designed as a core module within medical device automation lines, focusing on the high-precision assembly of shaft components such as transmission shafts and guide rods. It integrates advanced motion control, automated process flow, and intelligent quality monitoring to deliver consistent assembly results that meet stringent medical standards.

1.Multi-Axis Coordinated Control

The system employs servo motors, stepper motors, or linear modules to achieve precise positioning and motion synchronization of the KV axes—typically referring to a combination of rotational and linear axes. This ensures accurate alignment, coaxiality, and perpendicularity of components during assembly, maintaining tight geometric tolerances required by medical devices.

2.Integrated Automated Workflow

The workstation integrates feeding, positioning, pressing, inspection, and unloading into a closed-loop process, significantly reducing manual intervention. Each stage of production is automated to maintain consistent quality and optimize throughput.

3.Real-Time Quality Monitoring and Feedback

Built-in sensors—such as force and displacement sensors—continuously monitor assembly force, press-fit depth, and alignment. These parameters are automatically compared against predefined thresholds to ensure compliance with medical manufacturing standards such as ISO 13485.

Core Advantages

1.Higher Efficiency

The workstation adopts a multi-station parallel operation mode, drastically reducing the production cycle per unit compared with manual assembly, thereby increasing overall productivity.

2.Consistent Quality

By combining closed-loop control and real-time calibration, the system minimizes human error, enhances assembly accuracy, and ensures consistent quality across batches.

3.Flexible Adaptability

• Quick changeovers are possible through modular fixtures and programmable control, enabling production of different product models with minimal downtime.
• Workstation shielding allows manual loading when a specific station encounters an anomaly.
• Fixture shielding prevents feeding to any malfunctioning fixture position on the rotary table, maintaining continuous production.

4.Enhanced Safety

The system replaces manual operations in high-risk processes, effectively minimizing the risk of workplace injuries and ensuring operator safety.

Application Scenarios

1.Surgical Instrument Assembly

Used for assembling drive shafts in laparoscopic and arthroscopic instruments, ensuring smooth and precise motion control during surgery.

2.Imaging Equipment Assembly

Supports the precision installation of rotary shafts and guide rails in CT and MRI scanners, ensuring imaging stability and diagnostic accuracy.

3.Implantable Device Production

Applied in the precision assembly of shaft components for artificial joints and heart valves—critical to both product lifespan and patient safety.

Toward Smarter Medical Manufacturing

The KV-Axis Automated Assembly Workstation redefines precision assembly in the medical industry by integrating automation, quality assurance, and safety. As a trusted partner in advanced manufacturing, Han’s Laser continues to push the boundaries of automation technology—helping medical device manufacturers achieve higher productivity, consistent quality, and smarter production.
