Pin Alignment Inspection
The 2D Camera cannot measure the height position in z of the pins. The pins tips are tipped sharply and often do not have the highest point in the middle of the pin. The pins produce unwanted reflections.
Contactless QuellTech Q5 Laser Scanner can achieve this task with a high repeatability and speed and the help of the QuellTech 3D Vision software. The Scanner has to be positioned slightly angled to the surface to avoid unwanted reflections. The acquired pointcloud is cleared of outliers and a reference datum plane is isolated from the pointcloud of the object. The position of each pin top is calculated and compared against a tolerance envelope. Any one pin exceeding this tolerance envelope will lead to a NOT-OK output of the QuellTech 3D Vision software.
Thanks to QuellTech’s Q5 Laser Scanner and 3D Vision software, the client can get the advantage of 100% inline inspection of the pin position and height, thus significantly improving the quality of the electric assemblies .
