High-accuracy, high-speed AOI systems
VisionGauge® High-Speed, High-Accuracy AOI System inspection area

VisionGauge® Online High-Speed AOI systems are multi-processor based automated inspection systems that support concurrent image analysis and stage motion. It is a complete, fully-contained, self-standing unit in a full gantry configuration (i.e. the camera moves over the parts; the parts themselves do not move).

These systems are available with a resolution as fine as 0.1 micron. Multiple customizations are possible to meet application-specific requirements including modifications to the camera, optics, illumination module, fixtures, and more. An optional LASER module for automated laser profiling can also be integrated. We provide a wide range of travels, short and long, and a high-speed 240 VAC servomotor motion system for rapid, accurate positioning.

VisionGauge® Online High-Speed Automated Optical Inspection systems are powerful, but easy to use and easy to program. Fully-automated inspection and measurement programs (i.e. “recipes”) are created and modified using VisionGauge®’s intuitive Graphical User Interface. Programs can be saved to disk and read-in later on, allowing the possibility to manage different inspection routines for different parts.

VisionGauge® OnLine software includes a wide range of inspection and measurement tools, including:

  • Defect detection
  • Color verification
  • Pattern matching
  • High-accuracy measurements
  • Object counting & sizing
  • Assembly verification
  • Image analysis
  • Blob analysis
  • Presence/absence detection
  • Optical character recognition / verification
  • and much more…

High-Accuracy AOI Systems for 3D Inspection and Measurement

VisionGauge® High-Accuracy AOI Systems are fully-automated, full-color systems capable of high-accuracy measurements, automated defect detection, color verification, optical character recognition, and much more.

Automated Optical Inspection (AOI) system

The systems feature high-precision, crossed-roller movements with 0.1 micron encoder feedback and micro-stepping motor controller capable of ultra-fine movements. All axes can be automated and are controlled using an external multi-axis, 3-speed joystick or on-screen joystick controls.

The built-in “Auto-Focus” provides fast, accurate, and repeatable re-focusing. With VisionGauge® OnLine’s intuitive ‘teach’ mode, it is easy to create part programs, then let the system perform automated measurements. Programs can be automatically loaded, saved, and read-in from disk so they are ready to operate as soon as the part is in place. VisionGauge® OnLine’s extensive set of measurement tools and “Auto-Scan” feature is perfect for applications requiring automatic defect detection.

An open-frame stage with a glass insert allows for both transmitted and reflected illumination. Half- and full-bridge configurations are also available – for example, if your application requires heavy loads and long travels. Standard configurations are available ‘off the shelf’ and non-standard configurations can also be easily accommodated:  We have a great deal of experience with customization and can configure a system to meet your specific requirements.

"Customized" VisionGauge® OnLine OCR System, with integrated motion control and adapted optics & illumination

These Optical Character Recognition and Verification systems include adapted, low distortion optics and programmable, computer-controlled illumination, for maximum repeatability of results. They also include the entire VisionGauge® OnLine toolset. All of VisionGauge® OnLine’s image processing and analysis tools are thus available to automatically “cleanup” the image before carrying out the character recognition operation. This can dramatically improve results in the cases where there is contamination, background noise, difficult to read characters, etc…

VisionGauge® OnLine’s automated OCR / OCV tool is very robust in the presence of print defects and includes an advanced, proprietary “character splitting” algorithm to deal with print imperfections, smears, and other defects. VisionGauge® OnLine’s OCR / OCV tool is “user-trainable” and supports user-supplied character and symbol libraries.

Below you can view sample videos of a customized Optical Character Recognition / Optical Character Verification System. This is a motorized system that was adapted to process 272 parts at a time, on two trays. The system sits on a regular workbench.

Wire/Cable Cross-Section, Connectors, and Wire Bond Inspection Applications

High-Resolution Cable Cross-Section Inspection and Measurement

VisionGauge® high-resolution cable cross-section inspection and measurement systems are designed to carry out high-accuracy automatic measurements of multi-strand cables. Measurements include:

Cable Measurement Systems

  • Insulator thickness over every outer strand
  • Minimum insulator thickness
  • Cable outer diameter
  • Inner diameter (i.e. best fit through the point of minimum insulator thickness on each outer strand)
  • ID / OD concentricity
  • Insulator area

 

All of these results are obtained within seconds by pressing a single button. Furthermore, the measurements are completely operator independent.

These cable measurement systems can accommodate cables with any number of strands. These systems also include X-Y-Theta positioning mechanisms for quick & easy part alignment.

The VisionGauge® software that runs these systems has a simple and intuitive interface. You can use it to quickly and easily compute statistics, plot graphs and charts, and send measurement data to other software and database applications across your network. All of the measurement tools and functionality of the Standard Edition of the VisionGauge® software package are supported.

These cable and wire measurement systems are very rugged and well designed. They can be used on either the production floor or in the quality-control area and they require virtually no maintenance. They use specialized long-working-distance telecentric optics to produce very crisp & clear high-resolution imagery with extremely low distortion.

Standard configurations can accommodate cables and wires up 1.7″ in diameter and produce measurements with a resolution of 0.0001″ (i.e. 2.5 um). Non-standard configurations are also available.
