Aufgabe der Erfindung ist es, ein Überwachungssystem für die Qualität gespritzter Schichten vorzuschlagen, welches auch beim Verspritzen kalter Teilchen oder Tröpfchen funktioniert.task The invention is a monitoring system for the quality to suggest sprayed layers, which also during spraying cold particles or droplets works.
Diese Aufgabe wird erfindungsgemäß gelöst von einem Verfahren mit den Merkmalen des Anspruchs 1. Ausführungen der Erfindung sind Gegenstände von Unteransprüchen.These The object is achieved by a Method with the features of claim 1. Embodiments The invention is objects of dependent claims.
Erfindungsgemäß ist eine Beleuchtung vorgesehen, die die Gesamtheit oder Teile der Flugbahn der Teilchen oder Tröpfchen beleuchtet. Gleichzeitig ist eine Kamera vorgesehen, die die beleuchteten Bereiche aufnimmt und davon digitale Bilder erstellt. Erfindungsgemäß werden durch die relativ lange Belichtungszeit nicht einzelne Partikel, sondern ein ganzer Schwarm oder ein Ensemble von Teilchen oder Tröpfchen aufgenommen und abgebildet. Dieses Bild wird dann dargestellt oder durch eine rechnerische Auswertung weiter verarbeitet. Stets werden die Eigenschaften einer Vielzahl von Teilchen oder Tröpfchen aufgenommen. Durch die längeren Belichtungszeiten gegenüber dem Stand der Technik werden so zeitliche und räumliche Mittelungen der. Eigenschaften der Teilchen gemessen. Das digitale Bild ist keine Abbildung einzelner Teilchen, sondern stets eine Abbildung eines fliegenden Schwarmes, der durch die Reflektion des Lichtes an vielen Teilchen über ein Stück ihres Flugweges hinweg erzeugt wurde.According to the invention is a Lighting provided the whole or parts of the trajectory of the Particles or droplets illuminated. At the same time a camera is provided, which illuminates the areas takes and creates digital images of it. According to the invention due to the relatively long exposure time not individual particles, but a whole swarm or an ensemble of particles or droplets added and pictured. This image is then displayed or by a further processed computational evaluation. Always the properties a variety of particles or droplets added. By the longer Exposure times In the prior art, temporal and spatial averaging of the. properties the particle measured. The digital image is not a picture of a single one Particles, but always a picture of a flying swarm, the by the reflection of the light on many particles over Piece of her Flight path was created across.
Mit
der erfindungsgemäßen Beleuchtung
gelingt es, alle Partikel oder Tröpfchenstrahlen zu erfassen,
insbesondere auch solche, die aufgrund ihrer niedrigen Temperatur
nicht selbstleuchtend sind. Die bisher auf heiße Partikel beschränkten Verfahren – insbesondere
der
Als Beleuchtungsquellen können ein oder mehrere handelsübliche Beleuchtungen gewählt werden, wobei sich Laser besonders bewährt haben. Die Laserstrahlen können punkt-, linien- oder auch flächenförmig sein, wobei dazu ein breiterer Lichtstrahl oder ein aufgeweiteter Laserstrahl eingesetzt wird. Das Messvolumen sollte größer als 1 cm3 sein, wodurch sich eine Projektionsfläche ergibt, die im Bereich von 1 cm2 liegt. Dieser Bereich wird von der Kamera aufgenommen. Bevorzugt ist eine linienförmige Beleuchtung, die quer durch den Spritzstrahl oder in einem schrägen Winkel durch den Spritzstrahl gelegt wird. Die Kamera nimmt dann, je nach Standort einen Punkt oder eine Linie auf. Anhand der Lage der Linie oder der Länge der Linie kann auf die Partikelgeschwindigkeit oder auf die Teilchendichte geschlossen werden. Als Lichtquellen bevorzugt sind Laser, die im Dauerstrichmodus arbeiten. Die Wellenlängen sind bevorzugt im optischen Bereich, also zwischen 400 und 800 nm, wobei jedoch auch Licht im Ultravioletten oder im Infrarot verwendet werden kann. Entscheidend ist, dass die Kamera im gleichen Wellenlängenbereich arbeitet.As sources of illumination, one or more commercial lighting can be selected, with lasers have proven particularly useful. The laser beams may be point, line or even planar, with a wider light beam or a widened laser beam is used for this purpose. The measurement volume should be greater than 1 cm 3 , resulting in a projection area that is in the range of 1 cm 2 . This area is recorded by the camera. Preferably, a line-shaped illumination, which is placed across the spray jet or at an oblique angle through the spray jet. The camera then picks up a point or a line, depending on the location. Based on the position of the line or the length of the line can be closed on the particle velocity or on the particle density. Preferred light sources are lasers which operate in continuous wave mode. The wavelengths are preferably in the optical range, ie between 400 and 800 nm, but also light in the ultraviolet or in the infrared can be used. The decisive factor is that the camera works in the same wavelength range.
In einer bevorzugten Ausführung der Erfindung sind mehrere Beleuchtungsstrahlen vorgesehen, insbesondere zwei Beleuchtungsstrahlen, die den Partikel- oder Tröpfchenstrahl in unterschiedlicher Entfernung vom Düsenausgang beleuchten. Dadurch entstehen zwei oder mehrere Bilder, durch deren Vergleich wiederum auf Eigenschaften des fliegenden verspritzenden Mediums geschlossen werden kann.In a preferred embodiment The invention provides a plurality of illumination beams, in particular two illuminating beams, which are the particle or droplet beam illuminate at different distances from the nozzle outlet. Thereby create two or more images, by comparing them again closed on properties of the flying splashing medium can be.
Der oder die Beleuchtungsstrahlen können horizontal oder vertikal zum Spritzstrahl angebracht sein, wobei alle möglichen Winkel zwischen den Spritzstrahlen und den Beleuchtungsstrahlen sowie der Kamera möglich sind. Die Winkeleinstellungen der Kamera und der Strahlungsquelle zum Partikelstrahl sind im weiten Umfang frei wählbar, sie können im spitzen oder im stumpfen Winkel zueinander stehen, wobei jedoch vermieden werden sollte, dass die Kamera direkt in die Lichtquelle blickt. Alle anderen Anordnungen sind möglich, solange das von den Partikeln oder Tröpfchen reflektierte Licht die Kamera erreicht.Of the or the illumination beams can be horizontal or be mounted vertically to the spray jet, with all possible Angle between the spray jets and the illumination beams as well as the camera possible are. The angle settings of the camera and the radiation source to the particle beam are widely selectable, they can in pointed or at an obtuse angle to each other, but where It should be avoided that the camera is directly in the light source looks. All other arrangements are possible as long as that of the particles or droplets reflected light reaches the camera.
Die Erfindung lässt sich nicht nur beim Plasmaspritzen, beim thermischen Spritzen oder beim Kaltgasspritzen verwenden, sondern ist ebenso für andere Strahlprozesse (wie z.B. das Strahlen mit Sandpartikeln, mit Glaspartikeln, mit Korundpartikeln oder mit CO2-Pelets) geeignet. Die Partikel oder Tröpfchen können Flüssigkeiten sein, Halbflüssigkeiten, Pasten, schmelzflüssiges Gut, Lösungen, Dispers ionen oder Suspensionen. Als partikelförmiges Gut können Pulver, Körner, Kerne, Fasern oder Späne verwendet werden. Die Überwachung von Lackierprozessen ist ebenso möglich wie die von Pulverbeschichtungsprozessen, da auch die kalten Partikel und Tröpfchen von der erfindungsgemäßen Beleuchtung "sichtbar" gemacht werden.The invention can be used not only in plasma spraying, thermal spraying or cold gas spraying, but is also suitable for other blasting processes (such as blasting with sand particles, with glass particles, with corundum particles or with CO 2 pellets). The particles or droplets may be liquids, semi-liquids, pastes, molten material, solutions, dispersions or suspensions. As a particulate material, powders, grains, cores, fibers or chips can be used. The monitoring of painting processes is just as possible as that of powder coating processes, since the cold particles and droplets are also "made visible" by the illumination according to the invention.

Als Ergebnisgrößen können auch hier die Position der geometrischen Figur sowie ihre Kenngrößen, wie die Halbachsenlängen, die Seiten- oder Kantenlängen, die Durchmesser und ähnliche Maße ermittelt, berechnet, angezeigt oder anderweitig ausgewertet werden.When Result sizes can also here the position of the geometrical figure as well as their characteristics, like the half-axis lengths, the side or edge lengths, the diameters and the like Measures are determined calculated, displayed or otherwise evaluated.
Prozessveränderungen im gespritzten Strahl werden durch die resultierenden Formveränderungen der einbeschriebenen geometrischen Figuren automatisch sichtbar.process changes in the sprayed jet are due to the resulting shape changes the inscribed geometric figures automatically visible.
Die Belichtungszeiten der Einzelbilder können je nach Beleuchtungsquelle von 0,5 ms bis zu einigen Sekunden, bevorzugt im Bereich von 0,5 ms bis 2 s reichen, wobei sich durch die relativ lange Belichtungszeit ein hoher Integrationsfaktor sowohl über die Zeit als auch über den Raum ergibt. Ausgenommen sind Hochgeschwindigkeitsfotos, die im Bereich von 3 bis 5 μs oder kürzer liegen, da diese nur einzelne Partikel zeigen, nicht aber die Gesamtheit des Schwarmes.The Exposure times of the frames may vary depending on the illumination source from 0.5 ms to a few seconds, preferably in the range of 0.5 ms to 2 s, which is due to the relatively long exposure time a high integration factor both over time and over Room results. Exempted are high-speed photos taken in the Range of 3 to 5 μs or shorter lie, as these show only individual particles, but not the entirety of the Swarm.
