The Mechanical Positioning System is a critical subsystem within an Automated Optical Inspection Unit that provides precise, repeatable movement and positioning of inspection cameras, lighting systems, or the workpiece itself. It enables the optical inspection system to scan, focus on, and analyze specific areas of manufactured components with micron-level accuracy, ensuring reliable defect detection, dimensional measurement, and quality control in high-volume production environments. The system typically employs linear guides, ball screws, servo motors, and precision encoders to achieve controlled movement along multiple axes (X, Y, Z, and sometimes rotational). A motion controller receives inspection coordinates from the vision software, drives the motors to move the positioning stage to the target location, and uses feedback from encoders to verify position accuracy before image capture occurs. The system is designed for integration into automated optical inspection units used in the manufacturing of electronic components, printed circuit boards, and similar precision parts. It supports travel ranges from 300 to 600 mm, positioning accuracy of ±0.01 mm, and repeatability of ±0.005 mm, as per ISO 230-2. Maximum speed is 500 mm/s, acceleration ranges from 2 to 5 m/s², and load capacity is 10 to 50 kg. Resolution is 0.001 mm. Operating temperature range is 10 to 40 °C, relative humidity 20 to 80% non-condensing, and ingress protection IP54 to IP65 per IEC 60529. Supply voltage is 24 V DC ±10%, power consumption 150 to 300 W, and weight 80 to 150 kg. Materials include aluminum alloy, stainless steel, precision ball bearings, and polymer composites. These values are directory reference ranges; verify model-specific specifications with the manufacturer.
The system uses linear guides, ball screws, servo motors, and precision encoders to achieve controlled movement along multiple axes. A motion controller receives inspection coordinates from vision software, drives the motors to move the positioning stage to the target location, and uses encoder feedback to verify position accuracy before image capture. This closed-loop control ensures micron-level positioning repeatability.
