Measurement of Aluminum/Steel Ingots before Scalping

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.

Laser Scanner Solution: This task is a typical application of the high-resolution QuellTech 2D/3D Q5-880 Blue Laser Scanners. Two of these units are placed at the left and at the right of the measuring objects, at a defined inclination angle. Blue laser light in this case is a prerequisite, as the cast parts are red-hot, hence emitting in the red spectral range. Additionally, the client was in need of a software solution for the project, so a 3D point cloud processing application was implemented, performing inline and evaluating width, height and angle results. QuellTech customer is able to inspect continuously the product quality, simultaneously avoiding scrap. He uses the same system for more than 10 different types of castings. Errors caused by manual inspection are considerably reduced, and safety for personnel is enhanced.

Defects to be examined in this application are very small, their size is often lower than 0.5 mm – hard to discover by human eye. Rework in the course of the production of the final product however, proves to be complicated and expensive. Large rolls with a diameter of 2 m and a length of 10 m are very difficult to remove and to reinstall. In order to avoid corresponding inconveniencies, it is essential to support the manufacturing process of the rolls themselves by a reliable quality control in the form of an automated final inspection.As the Quelltech Q6 laser scanner features an extremely precise resolution of 4096 Pixels/Profile at a high scan rate, this model proved to be able to meet the requirements and was mounted onto the positioning stage of the grinding machine. Furthermore, an industrial measurement computer was added, used for the analysis software of the point cloud. On the basis of this configuration, the entire roll surface could be recorded on a helical path.

Four QuellTech Q6 3D- laser scanners are installed, mutually displaced by an angle of 90°. In this configuration, they are able to monitor the complete surface of the cable running through. It is important that the test does not lower the production speed, therefore very high sampling rates are required, supported by convenient data processing. The measured position of a defect is recorded in cable direction.
