Machine Vision

Multi-Point Quality Inspection

Multi camera systems with fixturing designed to allow visual access to the part can inspect multiple inspections at once. Robot mounted systems move sequentially to each inspection location all while in a single cycle. Using the program flexibility of the camera controller, image capture settings and specific vision tools can be changed dynamically for each inspection location. Inspections include:

 Additional robot axes can be added to increase the flexibility of part fixturing and allow a larger access area.

Short Shot Detection

Utilizing our knowledge of camera systems and  our robotic material handling experience we provide solutions that automatically detect shortshots at the injection molding process before additional value added work is done. Edge or profile inspection can detect missing material immediately. Alternatively 3D imaging capabilities can allow the vision software to “slice” the part along any defined plane in order to remove background information that may otherwise affect the inspection.

Assembly Confirmation

Specifically designed check stations can inspect visually for the complete assembly of a complex good. This can be used as a poka yoke to insure final product quality before leaving your facility. Advanced pattern tools and lighting techniques can identify objects and features in any orientation or scale. This allows the vision system to perform well even in extremely challenging situations.

Line Scan

Inspections needing high resolution and a large field of view are possible with a line scan solution. Utilizing the camera’s on board software image pixels can be collected in a single line as the target moves and stitch them together as a single complete  image for processing of the inspection. Fast moving and curved surfaces are additional applications where line scan technology can be used. Optionally if the target is stationary the camera can be mounted on the moveable surface and achieve the desired results.

Barcode and Optical Character (OCR) Recognition

Eliminate the need for additional traceability devices by utilizing the functionality to read many different 1D barcodes and 2D matrices as well as identify part numbers directly from the human readable text. 

OCR is available even in high hard to read text such as:

• Text with low contrast between type and background
• Text that varies in width and height
• Text that touches, is skewed, or is distorted
• Text with similar shapes, such as the letter “I” and the number “1”

Identification technologies insure a high read rate on all 1D and 2D codes.

3D Imaging / Structured Light

Industry leading technology now makes it possible to inspect parts in 3D. By taking many images of a fixtured part under various lighting conditions (Pattern Projection) the software is able to quickly reference the data points in each image and generate a 3 dimensional view. This new 3D image can be rotated, cropped, filtered and measured directly. Height and area measurements are common inspections for this application.
