Business Case: Surface Inspection in Cable Production

The QS View software package is intended for dimensional control in 2D or 3D QS-View 2D / 3D software for all measuring tasks 3D representation of an irregular body for determination of volume and weight. With the 2D / 3D software a wide variety of parameters can be processed and displayed, e.g. length, width, angle height, gap, presence, volume (resp. weight), seam geometry (height, width), gap dimensions. Due to the modular structure of the software, customized specialties can be added any time. Each module delivers the results to an individual output module. The universal SPC interface allows simple connection to S7 controllers via Ethernet. 2D / 3D software developer kits are available for integrators with corresponding knowhow.

Many materials cannot be measured tactilely, therefore non-contact thickness measurements become necessary. Especially e.g. with glowing materials, or wet processes, a continuous tactile measurement is nearly impossible. Furthermore, web speeds in plant engineering and production have increased, requiring a corresponding fast sampling rate of the measuring systems. In addition, high measuring widths are often required. Why is contact free measurement technology so perfect for this application? Can be used in any web width, Scalable measurement thicknesses from a few millimetres to several meters, Thickness and coating thickness can be measured for different materials, Vibrations of the web materials, can be compensated, Turnkey solution for mechanical engineering, Non-contact and non-destructive measurement method, Large distances to the measured object are possible, Measurement of free forms,

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.
