IN-PROCESS NON-CONTACT INSPECITON:
Our powerful Vision-Systems realize complex optical inspection tasks
Jenoptik multi-sensor capable vision systems have the capability of operating multiple cameras in parallel, or serially, and having very short cycle times allowing high part throughputs to be achieved. The multilingual software is very easy to use, with a comprehensive function library for 2D as well as 3D applications and enables detailed data management (e.g. statistical analyses).
Jenoptik vision systems can be integrated into machines, systems and tools, used in laboratory setups, or form the heart of complete inspection and sorting systems. They are fully capable of communication via multiple types of interfaces. They are indispensable in process automation and enable tool and process monitoring as well as processand quality control.
Typical inspection tasks
- High-precision external contour inspection of components
- Position detection
- Presence, completeness, and position control
- Attributive tests
Testing and sorting systems for the optical inspection of small parts
Optical inspection of manufactured components is handled by introducing pre-orientated parts into the system individually. Once introduced, the parts are optically scanned and then sorted based on the programmed criteria. For optimal performance, systems require the appropriate technical solution for handling and control – with the vision system becoming the heart and soul of the inspection and sorting solution.
Our inspection and sorting systems are for 100% inspection of small parts. Typical inspection features are the external visible geometry (diameters, radi, lengths, angles, detection of burrs, chipping, chips, etc.), but also attributive criteria (surface defects, color, etc.).
Components of our inspection and sorting systems consist of bunkers, conveyors, transport devices, sorting and packaging stations, and vision systems utilizing one or more camera solutions.
An essential performance criterion is the parts throughput, i.e. the number of parts inspected and sorted per minute, hour, or per shift. The throughput is limited by several factors, including manufacturing output, part-handling capabilities, part inspection speeds, all of which in turn depends on the inspection requirements. A high throughput requires continuous part throughput, a comparatively low throughput with clocked throughput:
- 100% - Testing with continuous throughput
- 100% - Testing with clocked throughput
- Customized systems for 100% testing
CLOCKED INSPECTION OF SMALL PARTS.
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
TESTING PART SPECFIC AUTOMATION EXAMPLE: AIR BAG COMPONETS AUTOMATED INSPECTION
- 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)
- Depending on the requirement profile
- Length / diameter up to approx. 100 mm
- Part geometry generally rotationally symmetrical, but also with free forms
- Testing accuracy 0.001 mm to 0.01 mm, depending on part size
- Throughput 10 - 200 parts/ minute
- Comprehensive inspection of the parts
- Inspection from multiple views
- Integration of further test equipment possible (e.g. eddy current)

In-process metrology for exact measurements during production Using the in- and post-process measuring systems for grinding technology, you can check the quality of your workpieces and optimize your production processes.
The in-process measurement control systems can be used in cylindrical grinding machines, for example. You use them to measure small, medium or large workpieces during the production process in the machine. The control units operate with maximum precision, reliability and repetitive accuracy. They continuously check the quality of your components, thereby ensuring that your production results are of consistently high quality.
To ensure process reliability, in-process measurement control systems automatically compensate for any tolerance variations, which can arise, for example, when grinding discs become worn or as a result of temperature fluctuations. In such cases, the in-process control systems monitor the measured values in real time, thus controlling the grinding process continuously until the nominal dimension has been reached. This process helps to minimize part rejection and necessary rework
Digital transfer technology
Digital transfer technology ensures maximum flexibility when configuring and controlling measuring heads. The in-process measurement control systems and digital measuring heads from Jenoptik are equipped with a modern fieldbus system for signal transmission. In contrast to analog measuring heads, this allows the measured values to be transferred digitally and thus with utmost reliability, speed and no interference.
The in-process measuring heads are extremely compact and robust. All components can be easily enclosed in a single housing and require minimal maintenance. This makes them ideal for use in harsh industrial manufacturing conditions. The measuring heads can also be equipped with an optional crash protection system, which prevents impact damage to the measuring system and workpiece.
