Inspection on the goods carrier system

Combination of 2D and 3D inspections for a comprehensive 100% inline component measurement on the goods carrier.

MABRI.VISION Multimodal 2D-3D inspection

Testing on the rotary clock

Our rotary clock inspection system enables a large number of inspections in the smallest of spaces, with manual or automatic assembly. 

How do we check

The inspection methods can be combined in a modular way and are based on the properties and features to be tested for your component. Depending on the requirements and component size, it is also possible to vary the size of the sensors.

Shadow casting system

When inspecting components according to the shadowing principle, the contours of the test parts are recorded with a high degree of accuracy. Difficult features such as contact probes and pins, which are often challenging for other 3D test methods, can also be measured in this way. By adding this test unit, a high degree of flexibility is achieved in the detection of difficult test features, even with short cycle times. However, this testing technology not only impresses with its precision, but also with its high measuring rate, even for complex testing tasks. The shadow cast inspection is therefore ideally suited for testing moving products directly in the production line.

Particularities

The shadow impact inspection is characterized by the measurement of features with a high aspect ratio, such as contact pins and pins. The results are robust and precise measurements, as well as a high degree of flexibility, which is made possible by the combination with linear technology and a rotation unit.

Telecentric 2D inspection

The precise inspection of large components using 2D camera technology is challenging. This is due on the one hand to the lack of 3D information and on the other hand to the requirements placed on the camera and optics. We address these challenges by using special telecentric lenses with a large field of view. In addition, we rely on the latest camera technology and thus achieve new possibilities in terms of precision and resolution. Furthermore, we use the 3D information from the other test stations to further optimize the alignment of the measuring plane.

3D line sensor

Line sensors are an effective and inexpensive solution for checking 3D features and complete component digitization. Particularly noteworthy are the speed and precision of the surface measurement. The use of the latest light section sensors enables highly precise measurements to be made even of multilayered, reflective and transparent materials.

Thanks to their high measuring speed with up to 6 million measuring points per second, 3D line sensors are ideal for use in inline test systems. The robust sensors easily withstand the specific requirements of industrial high-efficiency environments. With fast, three-dimensional recording of large surfaces, you can rely on both non-contact and seamless testing in your production.

Particularities

With up to 6 million data points per second, the 3D line sensor is one of the most widely used sensors in industrial inline use. Robust measurements with resolutions in the single-digit micrometer range correspond to the industry standard. The 3D line sensor can be used flexibly on different surfaces.
