Huayan Robotics (01021) high-precision optical coupling platform: providing diversified precision motion solutions for high-end optical communication manufacturing
The Zhitong Finance App learned that in the field of optical communication and optical module manufacturing, optical fiber coupling and precise alignment place extremely strict requirements on the accuracy, stability, and dynamic response of motion platforms. Huayan Robot (01021) has launched a high-precision XYZ series platform and a six-axis platform for this high-end application scenario. Among them, the XYZ platform includes 3 models, with strokes of 85*85*35, 160*160*60, 210*160*80, and repeated positioning accuracy of ±50nm. Using a coreless linear motor and a Z-axis air balancing device, it has low uniform waves, high stability and high motion accuracy. It is widely used in the optical fiber coupling industry, providing a reliable motion control foundation for processes such as optical module packaging, optical fiber array alignment, and waveguide coupling.

Coreless linear motors and Z-axis air balancing devices cooperate to achieve sub-micron level closed loop control
The Huayan robot optical coupling platform emphasizes multi-axis coordination and accuracy consistency in the overall architecture. The X, Y, and Z axes use iron-free linear motors to eliminate the cogging effect common with traditional iron-core motors from the driving source, so that the platform maintains extremely low speed fluctuations during uniform motion, thus meeting the requirements of optical fiber coupling for scanning uniformity and dynamic stability. The Z axis is equipped with an air balancing device, which effectively counteracts the influence of gravity on vertical motion. The entire platform is equipped with a high-resolution encoder to form a sub-micron closed loop control system, which can maintain excellent positioning stability regardless of continuous scanning or static positioning. This systematic design enables the platform to effectively suppress changes in light intensity due to speed fluctuations or static jitter during the fine coupling process, and improve coupling efficiency and process yield.
Self-developed motors, high-performance rails, and high-resolution encoders jointly shape a high-stability platform
The platform's product highlight is not a simple combination of individual components, but rather systematic optimization from motors, guides, and encoders to drive control. Huayan Robotics independently developed linear motors, so that the platform can achieve a compact layout in a limited space and at the same time have a high power density. The high-performance linear motion guide provides the platform with excellent positioning stability, especially suitable for image acquisition applications and precision processing scenarios. The addition of a high-resolution encoder allows the platform to achieve sub-micron level control accuracy and provides a basic guarantee for precise alignment. In addition, Huayan Robot has rich application experience and can provide fast and efficient customized services; the complete design, analysis, process and production system also guarantees product reliability and consistency from the source. Together, these advantages enable the platform to maintain stable performance during long-term operation, showing outstanding engineering value in fine processes such as optical fiber coupling.
At the core technical level, Huayan Robot adheres to the self-developed motor route and optimizes motor parameters for actual operating conditions, so that the motor can achieve the best working results under specific motion trajectories such as optical module coupling. The core team has more than 20 years of product accumulation in motors and motion control, and has experience in motor process analysis, electromagnetic analysis, temperature analysis, and major customer applications, providing solid support for platform performance. Collaborative optimization between software and hardware makes the platform excellent in terms of speed stability, positioning accuracy, and dynamic response, and further enhances the overall reliability and consistency of the system.
±50nm repetitive positioning accuracy and nanoscale static jitter meet the stringent requirements of optical fiber coupling
The total X and Y axis travel of the Huayan robot optical coupling platform is 160 mm, and the total travel stroke of the Z axis is 60 mm; the repetitive positioning accuracy of the three axes has reached ± 50 nm, reaching the sub-micron level. In terms of static jitter, the X, Y, and Z axes are as low as ±20nm, showing nanoscale stability. These indicators enable the platform to meet the strict requirements of the optical fiber coupling industry for accuracy and stability, and is particularly suitable for optical module manufacturing scenarios where high alignment accuracy needs to be maintained for a long period of time.
