Motion System (XY Stage) for AOI | Precision Positioning Component

Product Specifications

Technical details and manufacturing context for Motion System (XY Stage)

Definition

The Motion System (XY Stage) is a component used in Automated Optical Inspection (AOI) systems to provide precise, programmable movement of cameras, sensors, or inspection heads across a two-dimensional plane. It enables systematic scanning of workpieces or production lines, supporting comprehensive quality control and defect detection. The stage typically uses servo or stepper motors coupled with precision linear guides or ball screws to achieve accurate positioning. A controller receives movement commands and drives the motors to specific coordinates, enabling repeatable scanning patterns. The system is designed for integration into inspection equipment, with a travel range from 100×100 mm to 600×600 mm, positioning accuracy of ±0.5 to ±5 μm (per ISO 230-2), and repeatability of ±0.1 to ±1 μm (per ISO 230-2). Maximum speed ranges from 100 to 500 mm/s, and maximum acceleration from 0.5 to 2 g. Load capacity is 5 to 50 kg, including workpiece and fixture. Drive types include linear motor or ball screw, with feedback resolution from 0.01 to 0.1 μm. Supply voltage is 24 V DC ±10%, operating temperature is 10 to 40 °C, and ingress protection is IP40 to IP54 (per IEC 60529). Materials include aluminum alloy, stainless steel, and precision bearings; the stage weight ranges from 20 to 150 kg. These values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier.

Working Principle

The XY stage operates by converting rotational motion from servo or stepper motors into linear motion along two perpendicular axes. Motors drive precision ball screws or linear guides, moving a carriage that holds the inspection component. A controller sends position commands based on programmed coordinates, and feedback encoders provide real-time position data to close the loop, ensuring accuracy. The system can execute point-to-point moves or continuous scanning paths, with acceleration and speed profiles optimized for throughput and precision. The stage's rigidity and bearing quality directly affect positioning accuracy and repeatability.
