Our powerful Vision-Systems realize complex optical inspection tasks.

The vision system software includes an extensive function library with algorithms for fast image analysis and dimensional acquisition. It allows modeling of complex 2D and 3D applications and has tools for statistical analysis of the inspection results. The multilingual user interface is very easy to use and allows remote maintenance access so that support can be provided on short notice.

Many inspection applications are difficult, if not impossible, to solve with conventional tools of image processing. There are two main reasons for this:

• Classification - recognition of predefined parts or properties
• Anomalies - detection of any deviation from an ideal

Both challenges can be solved using artificial intelligence – or so called deep learning (machine learning). In contrast to the standard tools of image processing, no test job tailored to the specific article is created, instead a learning procedure is run using a large number of real images.

The learning process takes place on a separate training station, while the deep learning module for 100% inspection is integrated into our vision software. Supported by a power graphics cards, even fast applications can use the tools of artificial intelligence.

Grouping of the parts in defined classes

• Example classification of known defects
• Prerequisite availability of a sufficient number of parts per defect class

Detection of any deviations (anomalies/defects) from a trained ideal part

• Training on the basis of faultless parts, recognition of defects that were unknown at the time of training

Operating principle

• Continuous part transport on rotating glass ring
• Testing with 4-8 cameras from different perspectives
• Product-specific conveying and separation systems
• Sorting error related possible (e.g. for rework)

Dimensions

• W x D x H = 810 mm x 1,000 mm x 2,130 mm
• Height with open hood approx. 2,800 mm

Test parts

• Outer diameter up to approx. 50 mm
• Prerequisite: Parts must have a flat support surface for placing on the glass ring

Testing Services

• Testing accuracy 0.001 mm to 0.01 mm, depending on part size
• Part throughput up to 300 parts / minute

Benefits

• High part throughput
• Inspection from multiple views
• Minimal changeover effort

For comprehensive control, especially tests along the entire circumference, a rotation around the vertical axis is required. Based on the use of a rotary indexing table, or stepwise linear feed, clocked testing and sorting machines are high capable in this regard. The test parts are transferred to suitable centering devices such as mandrels, or clamping devices, and then rotated though 360° during the optical inspection. Cycled testing and sorting machines have one or more measuring stations and allow part sorting according to various criteria:

• Test criteria: geometry (dimensional accuracy), surface quality, sorting purity, etc.
• Performance: > 60 parts per minute (depending on parts and tasks)
• Test technology: CVS image processing with up to 8 high-resolution cameras
• Handling: storage hopper, feeding and packaging systems
• Dimensions: customer specific

Operating principle

• Handling of the parts specific to the article (lying, standing, hanging ...)
• Start-stop operation or continuous throughput
• Part rotation of 360° in start-stop operation in front of the cameras
• Testing with up to 10 cameras from different perspectives
• Sorting error-related possible (e.g. for rework)

Dimensions

• Depending on the requirement profile

Test parts

• Length / diameter up to approx. 100 mm
• Part geometry generally rotationally symmetrical, but also with free forms

Testing services

• Testing accuracy 0.001 mm to 0.01 mm, depending on part size
• Throughput 10 - 200 parts/ minute

Benefits

• Comprehensive inspection of the parts
• Inspection from multiple views
• Integration of further test equipment possible (e.g. eddy current)
