Recognoil® QB XL is a desktop surface contamination detector. The inspected objects are placed on the measuring table inside and irradiated with powerful UV emitters. This induces fluorescence of contaminants, which is captured by a sensitive detector. Recognoil® QB is also equipped with a source of white light, thanks to which it is possible to capture the real appearance of the part and easily document it. The evaluated area is 100x 100 mm.
Areas of application
Recognoil® QB is an efficient tool for mass inspection of small parts, but also for evaluation of larger complex surfaces. The entire part scanning process is completely non-contact, fast and requires no surface preparation. The device is commonly used to check the condition of the surface, especially before painting, galvanic plating, PVD and CVD coating, welding, soldering, gluing or intentional application of oil films during lubrication and preservation.
Under normal circumstances, the device can be used to detect oil and grease on all commonly used (bare) metal surfaces like steel, aluminium, copper, precious metals etc.
Principle and output
The essence of the detection principle is the induction of luminescence of contaminants, its capture and subsequent evaluation using the supplied software. The standard output of the measurement is the fluorescence intensity [F.U. - fluorescence units] resp. its mean value relative to the measured area and the image output (fluorescence map) showing the distribution of oil / grease substances on the surface of the part.
Fluorescence detection principle cannot be used for painted metal surfaces. Detection on plastic surfaces results in decreased sensitivity which strongly depends on the plastic substance composition and colour. We strongly recommend suitability testing of less common materials in our laboratory before purchase.
Supplied software
The Recognoil® QB comes standard with the advanced Recognoil® PRO software, which not only displays the scanned and evaluated areas, but also allows further data processing and contains several unique functions:
- display of image data and measurement results, display of 3D results,
- selection of areas of measured areas,
- name of the measurement (sample),
- sorting and searching for files,
- export files (pdf, jpg, txt),
- creation of protocols (photo documentation of parts, image and text notes),
- setting of measurement parameters,
- conversion of fluorescence units to oil thickness or area concentration,
- detailed statistics,
- setting pre-sets and limits,
- inserting object masks,
- calculation of over-limit pollution,
- calculation of frequency and size of spot contamination,
- possibility of additional implementation of functions according to individual customer requirements. (additional service)
Hardware requirements
To operate the device, it is necessary to connect it to a PC, laptop or tablet PC or to a company network using a data LAN cable. The supplied SW can be installed on any number of devices meeting the minimum hardware requirements listed below:
- x86/64 Quad-Core CPU, 4 GB RAM
- 1 GB of free disk space
- Microsoft® Windows 10 / 11 operating system
- Microsoft .NET Framework 4.5
Operator protection
The protection of the operator against the effects of UV radiation is ensured by closing the inspected object in the measuring compartment of the box. This also shades the light from the surrounding environment. If the device detects an imperfect closing of the door (magnetic contact) or an external light source, it will not allow the operator to continue scanning.
Package contents
The Recognoil® QB comes in the following basic configurations:
- Recognoil® QB with dimensions 615 x 650 x 600mm,
- Recognoil® PRO Software,
- measuring table,
- power supply cable,
- air blower (dust removal tool)
- user manual, measurement guide with Recognoil® QB,
- CE declaration of conformity,
- calibration protocol.
Device calibration
The device comes with a factory calibration protocol. Reproducible results over a long period of time are ensured if the instrument is stored, maintained and operated properly. To verify the condition of the device itself, it is possible to order standards and calibration samples.
Modularity
The construction of the device is modular and can thus be supplied in several different dimensions depending on the required size of the inspected parts. In the basic variant, the positioning of the measured objects is done using a manually controlled table, which can also be replaced by a fully automated positioning table or other special accessories. In addition, the function and appearance of the supplied software can be customized according to the customer's requirements, eg. for the needs of simple OK-NOK operation, connection to the company database, etc.
Maintenance
The device should be placed in a clean and dust-free environment. Contamination of the measuring head of the detector and the working space affects the measurement results. The compartment of the case and the optical part of the detector can be cleaned using an air-blower dust-removal tool for cleaning optical filters. The interior surfaces of the device and the surfaces close to the optical elements, as well as the glass filters, must be kept in clean condition and the operator should never touch these parts. The recommended regular inspection associated with the maintenance and calibration of the equipment is recommended in the interval of 6-12 months, depending on the frequency of use.
Warranty and service
The standard 24-month warranty only applies to manufacturing defects in the device, not to normal wear, or, contamination of the device. To ensure stable and reproducible results, we recommend sending the device at least once per year for regular maintenance (cleaning of optical elements, restoration of the anti-fluorescent coating of active surfaces) and control calibration (output calibration protocol is included).
