Particular Challenge: For the assessment of rotating parts, numerous parameters have to be taken into consideration: Concentricity, radial run-out and axial run-out (i.e. wobble); furthermore thickness, diameter, planarity and the absence of surface defects had to be examined. The solution developed by QuellTech consists in a configuration of three Q6 Laser Laser Scanners.Each of the lateral surfaces is assigned to its own scanner. In order to enable the thickness precisely to be determined, both laser lines are mutually oriented in opposite direction. The third scanner inspects the outer circumference of the wheel, this way measuring diameter and radial run-out. All of these scanners are subject to encoder signals supplied by the rotary axis and synchronously triggered, so possible defects on the wheel can precisely be localized. The measurement takes place at a resolution of ca. 30 µm, and a cloud comprising several millions of points are obtained.

Plastic Mold Part (AC Controller) Inspection At this point the manufacturer is looking for scratches and chips and dimension specifications manually. In this respect manual inspection is not a repeatable or trustworthy method to guarantee steady quality of goods. It will be demanding for a human worker to detect this for a long period. QuellTech Solution Plastic Mold Parts are easily measurable materials for QuellTech scanners. Using the QuellTech Q4-120 Laser Line Scanner it is possible to obtain very precise reflection free 3D point clouds. A Software making necessary detections in 3D point clouds can effortlessly check dimensions and find scratches or any other defect which allows the manufacturer to automatically parse outparts that do not pass the tolerance levels.

QuellTech Solution: The performance of a manual inspection cannot be compared with the speed and the repeatability of a contactless QuellTech Q4-1000 laser scanner. It is even possible to install several instruments in parallel to cover the whole width of the ingot with one single scan. These instruments are mounted on an existing portal and correctly synchronized, so that interaction of the laser light originating from the other scanners is excluded. The QuellTech laser line scanners produce 3D point cloud of the raw ingot surface, and the software calculates the coordinates of the highest and deepest levels of this surface. After scalping the flat surface can be scanned again for any defects. Benefits for the Client: Thanks to QuellTech’s wide area laser line scanners, the cycle times for ingot scalping could considerably be reduced, and excessive material scrap due to a too low scalping level is prevented.

Raytek GS150 thermal imaging systems enable automated quality control in glass bending, forming, annealing, and tempering processes. The GS150LE variant is especially designed for Low-E (low emissivity) glass / one-side coated flat glass. It features automatic emissivity correction. The systems are based on the Raytek MP150 infrared line scanner, which has a max. resolution of 1024 points per line, a max. 150 Hz scanning frequency, and an up to 90° wide field of view.
