Camera systems with telecentric lenses and the corresponding working distance are often too long to be integrated into a machine without space problems. No problem with the Cognex In-Sight based VisionUnit from senswork.

Using the example of the soldering point inspection, ZFokus allows the determination of the soldering volume, the detection of gaps in the soldering point and the evaluation of the shape of a soldering point. ZFokus shows its strengths wherever 2D systems today deliver excessive pseudo rejects when evaluating soldered joints due to fluctuating contrast variances or failing to reliably detect defect features.

Numerous errors can occur in the manufacture of soaps, and while the human eye can recognize that immediately, the way they look can vary widely. A multi-camera system consisting of incident light, transmitted light and 3D inspection reliably detects all defect features.

After the painting process of synthetic parts, they are subjected to a fully automatic surface inspection by a shape-from-shading system before further processing. This method allows the smallest surface defects such as paint pimples, scratches, inclusions, lint or other raised or recessed defects to be reliably detected. For this, our system uses eight lighting directions with eight partial images, which are offset by Shape from Shading to form a height map of the surface.

The supplied parts are removed from the supply line by a Scara robot and placed in a moving tray. Our camera technology controls the rotational position of the parts in the feeder, the position of the tray and the correct placement of the products in the tray.
