7SGA230 Electric Angular Positioning Platform
In scenarios such as optical system calibration, large-area sample angle scanning, solar simulator irradiation calibration, photoelectric detection, laser optical path debugging, etc., a larger swing range and stronger load-bearing capacity are often required for the attitude adjustment platform. The small travel angle positioning platform is difficult to meet the requirements of large-angle inclination scanning, and the lightweight platform body is prone to deformation and accuracy drift when carrying heavy optical components. The 7SGA230 electric angular positioning platform, as a large travel and heavy-load model of the 7SGA2 series, has a ±30° ultra-large adjustment range, which combines high load-bearing capacity with sub-degree-second-level positioning capability, perfectly solving the problem of automatic pitch adjustment for large-format, heavy samples and optical fixtures.
7SGA230 is equipped with a 400:1 precision worm gear transmission mechanism and a ring-shaped ball ring-shaped steel guide rail. The transmission is smooth and the gap control is excellent. Under 8 subdivision modes, the angle resolution can reach 0.0005625°, and the repeat positioning accuracy is stable and better than 0.004°. There is no obvious dead zone during forward and reverse switching, and there is no jitter during low-speed operation. Whether it is precise locking of a small angle or continuous angle scanning testing, the angle stability is persistent and reliable, ensuring the consistency of data for spectral acquisition and angle resolution testing.
The hardware performance has been comprehensively upgraded. The platform surface size is 160×160 mm, with ample installation space. The maximum center load is 30kg, and it can stably carry heavy loads such as large spectrometers, large-area photovoltaic samples, and imaging lens modules. The standard 57 stepper motors are equipped, with sufficient power reserve, and the maximum movement speed can reach 10°/s, balancing the debugging efficiency and motion stability. The stepper motor and worm gear are connected by high-quality elastic coupling, with good transmission synchronization and lower operating noise, suitable for long-term continuous automated testing in the laboratory.
The control interface adopts standard DB9 communication, which can directly match the 7SC series motion controller, supporting angle fixed-point positioning, reciprocating scanning, timing programming, multi-axis linkage, and easily building a fully automated testing process. The platform body is internally equipped with bidirectional limit switches, effectively preventing overtravel impact and protecting optical components and positioning bodies; it supports optional selection of photoelectric zero-position sensors to achieve automatic zeroing upon power-on, facilitating long-term cyclic experiments and equipment integration into automated production lines.
The structure is made of thickened high-strength aluminum alloy through one-piece processing, with hard anodizing for wear resistance and corrosion prevention, featuring outstanding rigidity. The platform surface is less likely to deform under heavy-load conditions. The unique coaxial design allows two 7SGA230 units to be orthogonally stacked to form a concentric two-dimensional pitch adjustment module; the platform is fully equipped with standard threaded array holes, which can be freely combined with electric linear stages, elevators, and rotating stages, quickly building a multi-dimensional precise motion system, suitable for integrating various non-standard detection equipment.
Different from conventional small travel angle positioning platforms, 7SGA230, with a ±30° ultra-large swing stroke, is particularly suitable for solar cell angle response testing, large-range attitude calibration of optical interference systems, infrared imaging angle calibration, and remote sensing simulation light source angle adjustment, etc. There is no need to repeatedly disassemble the samples, and a single stroke can cover the complete test range, significantly reducing the debugging workload.
From key laboratories of universities, research institutes' cutting-edge projects, to photovoltaic detection equipment and photoelectric automated production lines, the 7SGA230 electric angular positioning platform, with its three core advantages of large travel, high load-bearing capacity, and high precision, fills the gap in wide-range heavy-load inclination adjustment requirements. The wide pitch range meets the needs of precise measurement control, and the solid body supports long-term stable operation.
Expanding the experimental boundaries with large travel and achieving precise measurement with high load-bearing capacity. The 7SGA230 electric angular positioning platform provides a reliable motion solution for large-range attitude automation control.
