Quality assurance is the top priority in the automotive industry. The error tolerances are low. With the ZScan 3D multi-sensor system from senswork, large assemblies made of aluminum or other sheet metal, e.g. oil pans, can be measured three-dimensionally and compared against CAD data.

Volume determination on the production line plays a major role in the food industry. It must be ensured that exactly as much product is packed as is printed on the packaging. With our 3D multi-sensor system ZScan, we can scan cut-to-size or block-format goods such as meat, fish or cheese without shadows and thus determine the exact quantity.

In the production of clay bricks, it is critical to ensure that the bricks are dimensionally accurate. This prevents bricks from leaving the factory beyond the manufacturing tolerances and, under certain circumstances, costly return transport from the construction site. For the reliable detection of defects, senswork has developed the BrickChecker, which can be seamlessly integrated into an existing production line.

There are many dimensional data on saw blades that ultimately determine the cutting quality and service life. For the inspection of diamond saw blades, senswork, together with the company Plattner, has equipped a measuring station with a double-head laser scanner system, which measures and records all tooth geometries, blade width, cutting width, angularity, and diameter during the run.

An automotive supplier manufactures connector strips for the specialty "autonomous driving". These strips must be extremely precise and should be tested using an inline process. The ZFokus from senswork enables pin heights to be determined with an accuracy of ± 0.01 millimeters.

As part of a fully automated production, one and the same system should test various connector geometries such as connector strips, Fakra connectors or other HF connectors and their labels. Features such as pin positions, wobble circles and coding features are to be checked. As part of the label inspection, textual content is automatically read and compared using OCV, and symbols and graphics are checked for completeness and print quality / legibility.

Manufacturers of connector components are confronted with ever increasing demands on the precision of the plug connections and their compactness. The ZFokus from senswork makes full use of its advantages in the coplanarity inspection of SMD assemblies and in the pin height check.

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.

In high-frequency technology, the quality of the installed coaxial cables, especially in the connection area of the cables, plays a major role in the subsequent signal quality. The measuring system developed by senswork records the inner conductor tip three-dimensionally, and is thus able to precisely measure the spatial deflection of the tip as well as the protrusion from the outer conductor shield.

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.

In a fully automated handling system with a 6-axis robot, a 3D laser scanner captures components in flight. The robot presents three components per second to the scanner. This records the component geometry in 3D and measures a recess on the component at several positions.

Using a 4-fold laser scanner setup, metal rods are checked for correct surface and geometric tolerances. With a 3D calibration, the laser scanners deliver 3D data sets in the same calibrated coordinate system. This method can also be applied to continuous materials. The measuring system is used to measure metal rods and to check the surface for flaws. It is moved over the rod at a speed of up to 100 mm / second.

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.

In this system, Euro pallets are fed via a roller conveyor belt to a robot system, which automatically removes the sack layers and places them on a longitudinal conveyor belt. Using a time of flight camera from senswork, the positions of the plastic bags are recognized fully automatically and transferred to the robot coordinate system. The detection accuracy of the system is ± 10 mm, and thus allows precise pick-up by the suction gripper mounted on the robot.
