In high-end and precise scenarios such as optical alignment, precise component coupling, laser debugging, and sample posture calibration, simple three-axis translation often cannot meet the requirements for correcting minor angle deviations and fine-tuning the posture. The multi-dimensional adjustment capability of translation plus angle linkage is the key to improving experimental accuracy and optimizing alignment effects. To meet the urgent needs for high-precision posture calibration and compound displacement control, Saifan Optoelectronics has launched the 7SAA401 electric combined displacement stage. It breaks through the limitation of traditional three-axis pure translation displacement stages by achieving four-dimensional electric adjustment of three-axis linear translation plus single-axis rotation. With precise micro-control, integrated design, and high adaptability, it solves industry pain points such as precise alignment angle deviation, cumbersome posture adjustment, and redundant assembly of multiple devices.
The four-dimensional integrated combination design enables synchronous rotation and translation adaptation to complex calibration scenarios.
Unlike conventional three-axis pure translation displacement stages, the 7SAA401 adopts an innovative modular four-dimensional integrated architecture, composed of a high-precision electric translation stage and a precise electric rotation stage. It stably realizes four-dimensional automatic adjustment of X, Y, and Z three-axis linear translation plus single-axis angle rotation, perfectly balancing precise positioning and fine posture calibration. The equipment is equipped with standard travel for common precision conditions, with uniform controllable translation displacement and precise adjustment of rotation angles. It can simultaneously complete sample position alignment, angle correction, and posture fine-tuning, without the need for additional rotation equipment, completely eliminating the problems of cumbersome multi-device assembly and debugging, poor coaxiality, and large cumulative errors.
The entire machine adopts an integrated precision assembly process, with a compact and rigid structure, high-axis system coordination accuracy, no looseness or offset during operation, and minimal assembly errors of the combined structure. The lightweight and regular body does not occupy the experimental space and is compatible with various standard optical platforms, experimental fixtures, and automated integration systems. It can be used independently for laboratory precision fine-tuning experiments or quickly integrated into automated detection, precision coupling production lines, with full flexibility of adaptation.
Micrometer-level precise control, balancing smoothness and accuracy
Precise fine-tuning is the core core strength of the 7SAA401. The translation unit of the equipment is equipped with a high-precision ball screw and high-precision linear guide rail, processed by professional pre-tightening and gap elimination technology. The transmission is smooth without jamming, low-speed micro-motion does not shake, the repeat positioning accuracy is stable and controllable, and the total displacement error is extremely small. Combined with a dedicated electric rotation unit, the angle adjustment is delicate and precise, capable of correcting minor angle deviations, perfectly adapting to scenarios with high precision requirements for position and angle such as precise coupling and optical path fine-tuning.
The equipment is equipped with standard stepper motors and DB9 universal interfaces, which can be seamlessly adapted to the 7SC series motion controllers to achieve programmed and automated precise control, with rapid dynamic response and strong operational stability. It is equipped with an optical zero position calibration system and both ends limit protection structure, effectively avoiding overtravel loss and positioning drift problems, maintaining high precision output even under long-term high-frequency fine-tuning and reciprocating operation. The body is made of high-strength aluminum alloy material, processed by anodizing technology, resistant to vibration, deformation, and wear, suitable for laboratory normal conditions and mild industrial precision operations. In vertical operation scenarios, an optional power-off protection component can be selected as needed to prevent power-off settlement and posture deviation, providing dual guarantees for safety and stability of the operation.
