Quick Set-up Icon Driven Menu System
Learning to operate the I-Lign system is easy with image based buttons. Icons are used for each function needed to teach and align a substrate to the stencil/screen. Creating a recipe is completed in four steps – (1) move the camera (if this is a moving camera system) to the location of the fiducial (2) learn the stencil/screen target (3) learn the substrate target and (4) calibrate the system.
Easy-to-use Light Pen Operator Interface
Any printing environment is inherently dirty. Mechanical devices such as keyboards, a mouse or trackball get dirty quickly and fail to operate consistently. They become high failure items that mist be replaced frequently. Although the cost may be low, the constant interruption is annoying.
The solution is the use of a Light Pen as the main input device between the operator and machine. All actions are performed with the click of the light pen to the display. Dirt deposited on the outside of the pen can be cleaned safely using a saturated wipe or normal isopropyl alcohol.
Supports up to Four Stationary or Roving cameras
Flexibility in the vision software provides for a number of input options. In some cases, multiple stationary cameras mounted above the substrate and stencil/screen afford the best solution. In other cases, a roving camera located between the substrate and stencil/screen may be needed. Either case can be accommodated by the I-lign system.
Three Locating Methods
Image locating can be performed using any of three different methods. Correlation method provides a pattern matching or pattern recognition where the new target is compared against a stored reference image. Boundary Tracking is also considered blob recognition where the geometric features of the target are identified and reported. The final method is a Hybrid combination of the correlation and boundary tracking that uses a proprietary algorithm to combine these two method into a precise locating tool.
Recognizes All Standard Fiducial Types
By providing three locating methods, I-lign can recognize virtually any target currently in use with automation. In fact, it can recognize virtually any target period. Typical targets (fiducials) used with vision systems are:
l,£, ¤, ¡, #, +, ., u,<,
Automatic Calibration
All systems that combine mechanical and optical apparatus need a way of correlating actual motion with desired movement. This is typically done by means of a calibration routine that drives the mechanism a specified distance and then uses the optics to measure the actual motion. With the I-lign vision engine, this is done automatically with the touch of a button. Motion control instructions are passed to the motor control system for specified movement. The target is then located at each motion step allowing the internal calibration system to correlate the mechanism movement to the optics. All user subjectivity is removed, as is the need for advanced training of an operator or set-up person thereby increasing accuracy and decreasing changeover time.
Pentium PC Based Vision System with Windows™ 95 Operating System
i-lign Vision Systems are designed for the standard Pentium PC platform using Windows 95 operating system. A basic computer is included with the system, configured to allow I-lign to take full advantage of the required image capture board. This hardware and operating system combination is in use globally. Windows 98 or Windows NT (client) is available as a substitute operating system upon request.
Standard OLE Interface for Integration
Since the I-lign system is designed for use either as a module integrated into your product or as a complete vision system, all portions of the software are OLE compliant. This allows rapid integration of the vision engine into your product by using standard, Microsoft OLE statements. For users who require a complete vision system, this allows further customization for sharing information between applications.
Optional Motor Control System
Many machine designers and builders have already determined which motor and drive systems are needed to reach their product design goals. For those who are in the early stages of development, a complete motor control system is available as an option. Combining this option with the standard I-lign vision engine reduces the critical time-to-market needed in today's business environment. The motor control systems are available for multiple axes of motion. Please contact ORS directly with your specific requirements for additional information. |
