1、Ultra-High-Speed Motion Control Software Algorithm
The ultra-high-speed motion control software is based on H₂ and hybrid robust control algorithms, which maintain the system's stability, dynamic characteristics, and steady-state performance under specific uncertain conditions. This significantly improves the efficiency and precision of multi-axis synchronized motion control, greatly enhancing overall work efficiency. By applying this ultra-high-speed motion control software, functions such as arbitrary three-axis linear interpolation, arbitrary two-axis circular interpolation, and arbitrary three-axis helical and continuous interpolation can be achieved. It also supports simultaneous control of up to 12 axes, or four groups of three-axis interpolation working concurrently, with the capability to exchange commands for 12 motors within a 1 ms instruction cycle.
2、Sub-Micron Precision Motion Platform
The sub-micron precision motion platform technology utilizes a precision stage driven by linear ultrasonic motors, achieving positioning accuracy at the micrometer or even nanometer level, while simultaneously providing travel ranges up to hundreds of millimeters. Experimental results show an average resolution of 50 nm, a maximum operating speed of 0.5 m/s, acceleration greater than 15 m/s², positioning accuracy of 100 nm, and a settling time of less than 10 ms. Sub-micron precision motion platforms are widely used in fields such as microsurgery, high-density optical storage, and lithography scanning control, offering exceptionally broad application prospects.
3、AI-Based Visual Defect Inspection Technology
can replace manual inspection for defects such as roll marks, scratches, creases, and stains on metal surfaces; it can also detect defects like dirt, damage, double cells, and scratches on chip surfaces. Additionally, it is applicable to appearance defect detection of precision workpieces and defect detection under complex backgrounds.
