Material
Nonferrous samples, diameter up to 60 mm, round with parallel surfaces
Operation mode
Robot automation
The HERZOG MetalLab is the state-of-the art solution for automatic preparation and analysis of non-ferrous samples. Both optical emission and X-Ray spectroscopy analyzers can be integrated. The outstanding features of the MetalLab are flexible configuration of all components, adaptability to the specific requirements of the customer and the small footprint. The MetalLab is available in conventional laboratory design or as a container version.
The operator registers the samples using a registration terminal, barcode scanner or the batch-registration function of the PrepMaster. Various input options are available including, e.g., conveyor for normal and high-priority samples, spiral magazines or trays for sample batches. The MetalLab fits into a standard size container and can be stored next to the production site to allow immediate analysis. In this case, the operator registers the production sample using the registration terminal outside of the container and inserts the sample via an input flap. Within the MetalLab, an industrial robot takes care for handling of production, recalibration and control samples.
The MetalLab includes the HN-FF milling machine for coarse and fine machining of the sample surface. Alternatively, the HN-SF can be integrated for cutting of, e.g. mushroom-type samples and subsequent surface milling. After preparation the sample is transported to the analyzer. Optionally, an automated vision system checks the sample surface for pass/fail detection and spark point determination. Following analysis the sample is transferred to an output magazine or container. As an option, the sample can be marked using a wax printer, dot-matrix printer or label printer.
The functions of the MetalLab have been streamlined to guarantee the highest possible analytical performance as well as fastest possible sample preparation and analysis time. Furthermore, the mechanical systems and automation software have been tuned to reduce the operator’s intervention to a minimum.
The MetalLab offers the following standard and optional functions:
Handling of production samples
Handling of recalibration and control samples
Registration of samples
Worksheets
Vision-based Spark point determination
Optionally, a vision system can be integrated for automatic spark point determination. The operator can define criteria for inclusion or exclusion of sample surface areas from analysis. Furthermore, it is possible to specify primary and second-tier ROI’s used for analysis. As a matter of course, the robot shifts the sample between sparks automatically and precisely. If no appropriate analysis sector is available the sample is remilled or discharged from the system whatever is specified in the PrepMaster settings.
Marking of production samples
After completion of analysis, production samples might be marked for archive purposes. The SteelLab system offers various marking systems including wax printer, dot-matrix printer or label printer.
Stand table and electrode cleaning
The optical emission spectrometer may not include an automatic spark stand cleaning. In these cases, HERZOG can offer a cleaning device that can be easily mounted on the OES. The spark stand cleaning provides a thorough cleaning of the electrode and the surrounding stand table without involving the robot. The cleaning parameters can be controlled using the PrepMaster software.
