Beschreibung Titel: Kameraschutzgehäuse Description Title: Camera protective housing
[0001] Die vorliegende Erfindung bezieht sich auf Gehäuse zur Aufnahme und Halterung von Industriekameras.The present invention relates to housings for receiving and holding industrial cameras.
[0002] Industriekameras haben in der Produktion von Konsumgütern einen festen Platz eingenommen. Sie werden eingesetzt zur Überwachung der Produktion, zur Qualitätskontrolle und als Bestandteil von Steuerungssystemen. [0003] Aufgrund der oftmals widrigen Bedingungen in Produktionsumgebungen müssen die Kameras, um eine einwandfreie Funktion auch über einen langen Zeitraum zu gewährleisten, in einer Art und Weise montiert und vor Schmutz und Feuchtigkeit geschützt sein, die eine Beeinträchtigung der Kamera verhindert. Von besonderer Bedeutung ist ein entsprechender Schutz bei Kameras, die zur digitalen Bildverarbeitung eingesetzt werden, wie z.B. Smart Kameras, die einen Prozessor zur Bildverarbeitung enthalten, aber auch jeder andere Art von digitaler Kamera (auch Überwachungskameras). Als Smart Kameras werden digitale Kameras bezeichnet die die komplette Bildverarbeitung, also die Auswertung von Bilddaten in der Kamera selbst durchführen. Diese Kameras enthalten bereits einen Computer - inklusive Prozessor - der nach entsprechender Programmierung die Bilder auswertet und entweder Messergebnisse versendet oder über die digitalen Schnittstellen direkt Equipment ansteuern kann.Industrial cameras have taken a firm place in the production of consumer goods. They are used to monitor production, quality control and as part of control systems. Due to the often adverse conditions in production environments, the cameras to ensure proper operation over a long period must be mounted in a manner and protected from dirt and moisture that prevents interference with the camera. Of particular importance is appropriate protection in cameras used for digital image processing, such as e.g. Smart cameras that contain a processor for image processing, but also any other type of digital camera (including surveillance cameras). Smart cameras are digital cameras that perform the complete image processing, ie the evaluation of image data in the camera itself. These cameras already contain a computer - including a processor - which, after appropriate programming, evaluates the images and either sends measurement results or can directly control equipment via the digital interfaces.
[0004] Mit zunehmender Rechenleistung - üblich sind mittlerweile Prozessoren mit 1 Ghz Taktfrequenz - steigt auch die Wärmeabgabe dieser Systeme - die Prozessortemperatur kann hierbei bis zu 90 Grad Celsius erreichen. [0005] Die konventionelle Montage dieser Kameras in geschlossenen Schutzgehäusen ohne Ableitung der freigesetzten Wärme würde zur Aufheizung der im Gehäuse befindlichen Luft und damit schließlich zur Überhitzung der Kamera führen. [0006] Die Kameras enthalten in der Regel Gewindebohrungen - entweder nur am Kamerafuß oder an mehreren Seiten des Kameragehäuses. [0007] Die Befestigung im Kameraschutzgehäuse erfolgt in Regel über ein Zwischen- blech, eine so genannte "Slide-out platform", mit dem die Kamera über die Gewindebohrungen an einem Fuß oder Kameragehäuse verschraubt wird. Dieses Zwischenblech mit montierter Kamera wird dann mit dem Schutzgehäuse verschraubt oder verklemmt. Hierzu werden die in der Kamera enthaltenen Gewindebohrungen verwendet. [0008] Diese herkömmlichen Lösungen schützen zwar hinlänglich vor Staub und Feuchtigkeit, fuhren jedoch oftmals dazu, dass sich aufgrund der Kapselung ein Wärmestau innerhalb des Gehäuses entwickelt, die die Elektronik der Kamera beschädigen kann. [0009] Es besteht also ein Bedarf an Kameraschutzgehäusen, die einen hinreichenden Schutz der Kamera vor Staub und Feuchtigkeit bieten und andererseits gewährleisten, dass ein Wärmestau innerhalb des Gehäuses vermieden wird.With increasing computing power - are now common processors with 1 Ghz clock frequency - increases the heat output of these systems - the processor temperature can reach up to 90 degrees Celsius. The conventional installation of these cameras in closed protective housings without dissipating the heat released would lead to the heating of the air in the housing and thus eventually to overheating of the camera. The cameras usually contain tapped holes - either only on the camera foot or on several sides of the camera body. The attachment in the camera protective housing is generally carried out via an intermediate plate, a so-called "slide-out platform", with which the camera is screwed onto a foot or camera housing via the threaded bores. This intermediate plate with mounted camera is then screwed or jammed with the protective housing. For this purpose, the tapped holes contained in the camera are used. Although these conventional solutions protect adequately against dust and moisture, however, often lead to the fact that due to the encapsulation, a heat accumulation develops within the housing, which can damage the electronics of the camera. Thus, there is a need for camera housings that provide adequate protection of the camera from dust and moisture and on the other hand ensure that heat accumulation is avoided within the housing.
[0010] Vorgesehen ist eine Vorrichtung zur staub- und feuchtigkeitsdichten Befestigung von Kameras in einem Schutzgehäuse, wobei das Schutzgehäuse aus einem wärmeleiteden Material besteht, mit zumindest einer Spanneinrichtung und zumindest einem Wärmeleit- block, die zwischen sich einen Klemmraum zur Aufnahme einer Kamera definieren, wobei der Wärmeleitblock aus hochwärmeleitfähigem Material gemacht ist und in großflächigem Kontakt mit der Innenwand des Schutzgehäuses steht. Bei dieser Vorrichtung wird die Kamera nicht wie üblich an vorgesehenen Gewindebohrungen befestigt (verschraubt), sondern mit Hilfe geeigneter Spanntechnik in das Gehäuse eingeklemmt, was nicht nur eine höhere Flächenpressung zwischen Kamera und Schutzgehäuse ermöglicht und somit einen deutlich besseren Wärmeübergang von der Kamera auf das Schutzgehäuse, sondern auch eine größere Freiheit bei der Anordnung der Kamera in dem Schutzgehäuse. Die in der Kamera freigesetzte Wärme wird maßgeblich über den Wärmeleitblock in das Schutzgehäuse abgeführt, wobei auch die Spanneinrichtung so ausgestaltet sein kann, dass sie zur Wärmeabfuhr beitragen kann.[0010] A device is provided for dustproof and moisture-tight fastening of cameras in a protective housing, wherein the protective housing consists of a heat-conducting material, with at least one clamping device and at least one heat-conducting block defining a terminal space between them for receiving a camera, wherein the Wärmeleitblock is made of highly heat conductive material and is in extensive contact with the inner wall of the protective housing. In this device, the camera is not attached as usual to provided threaded holes (screwed), but clamped by means of suitable clamping technology in the housing, which not only allows a higher surface pressure between the camera and protective housing and thus a much better heat transfer from the camera to the protective housing , but also a greater freedom in the arrangement of the camera in the protective housing. The heat released in the camera is significantly dissipated via the Wärmeleitblock in the protective housing, wherein the clamping device can be configured so that it can contribute to the heat dissipation.
[0011] Es ist weiterhin bevorzugt, dass die Spannvorrichtung zustellbare Keile aufweist, deren gegenläufiges Verschieben zu einer Änderung der Ausdehnung der Spannvorrichtung in Spannrichtung führt. Die Verwendung von anstellbaren Keilen ist nicht nur eine sehr effektive, stufenfreie und kostengünstige Lösung sondern bietet aufgrund des großflä- chigen Kontaktes zwischen den Keilen einerseits und zwischen Kamera und Innenwand des Schutzgehäuses andererseits ein großes Wärmeabfuhrpotential, insbesondere, wenn die Keile aus einem wärmeleitfähigen Material gemacht sind.It is further preferred that the clamping device has undeliverable wedges, the opposite displacement leads to a change in the expansion of the clamping device in the clamping direction. The use of adjustable wedges not only provides a very effective, stepless and cost effective solution, but on the other hand, provides high heat dissipation potential due to the large area contact between the wedges and between the camera and the inner wall of the protective housing, especially if the wedges are made of a thermally conductive material are.
[0012] Alternativ kann die Spanneinrichtung aus zwei Klemmblöcken mit Exzen- terschrauben gebildet sein, die mit dem Boden der Kamera verschraubt sind und sich zwi- sehen Kameraboden und Innenwand des Gehäuses verspannen. Schließlich kann auch eine Mischform aus anstellbaren Keilen und Klemmblöcken mit Exzenterschrauben Anwendung finden, um die Kamera im Gehäuse zu fixieren. [0013] Der "Wärmeleitblock" wird auf die Kamera aufgelegt und greift vorzugsweise über die Gehäusekanten der Kamera und lässt sich daher im Gehäuse nur zusammen mit der Kamera bewegen.Alternatively, the clamping device can be formed from two clamping blocks with eccentric screws, which are screwed to the bottom of the camera and clamp between the camera base and the inner wall of the housing. Finally, a mixed form of adjustable wedges and clamping blocks with eccentric screws can be used to fix the camera in the housing. The "Wärmeleitblock" is placed on the camera and preferably engages over the housing edges of the camera and can therefore be moved in the housing only together with the camera.
[0014] Die Vorrichtung nach Maßgabe der Erfindung kann sich weiterhin dadurch aus- zeichnen, dass Spanneinrichtung und Wärmeleitblock verschieblich in dem Schutzgehäuse angeordnet sind. Dies wird insbesondere dadurch gewährleistet, dass sämtliche Elemente, nämlich Spanneinrichtung, Kamera und Wärmeleitblock durch Anstellung der Keile der Spanneinrichtung oder verdrehen der Exzenterschrauben gegen die Innenwände des Schutzgehäuses verklemmt verspannt werden und somit frei innerhalb des Schutzgehäuses angeordnet werden können.The device according to the invention can furthermore be distinguished by the fact that clamping device and heat-conducting block are displaceably arranged in the protective housing. This is ensured in particular by the fact that all elements, namely clamping device, camera and heat conducting block are clamped clamped by employment of the wedges of the clamping device or rotating the eccentric screws against the inner walls of the protective housing and thus can be freely arranged within the protective housing.
[0015] Weiterhin kann die Vorrichtung so ausgestaltet sein, dass der Wärmeleitblock auf seinen Klemmflächen mit Wärme leitfolien versehen ist, die eine Anpassung an die Konturen der zu verklemmenden Kamera und der Innenwand des Schutzgehäuses ermöglichen. [0016] Weitere Eigenschaften der Erfindung ergeben sich aus der folgenden Beschrei- bung einer bevorzugten Ausführungsform der Erfindung unter Bezugnahme auf die beigefügten Zeichnungen, die jedoch rein illustrativ und nicht beschränkend zu verstehen sind. Darin zeigt:Furthermore, the device may be configured so that the heat conducting block is provided on its clamping surfaces with heat leitfolien that allow adaptation to the contours of the camera to be clamped and the inner wall of the protective housing. Further characteristics of the invention will become apparent from the following description of a preferred embodiment of the invention with reference to the accompanying drawings, which are, however, to be understood as illustrative and not restrictive. It shows:

[0019] Fig. 3 eine detaillierte Querschnittsansicht des Schutzgehäuses nach Fig. 1FIG. 3 is a detailed cross-sectional view of the protective housing of FIG. 1. FIG
[0020] Die Figuren 1 und 2 zeigen in unterschiedlichen Schnittansichten das Wirkprinzip der Ausführungsform der Erfindung. Gezeigt ist ein Schutzgehäuse 2, z.B. ein Alumini- umprofϊl, das an beiden Enden mit Glas oder Metal verschließbar ist, mit einer Spannein- richtung 4 aus anstellbaren Keilen 4a und 4b und mit einem der Spanneinrichtung 4 gegenüberliegenden Wärmeleitblock 6 aus hochwärmeleitfähigem Material, wobei die Spanneinrichtung und der Wärmeleitblock zwischen sich einen Klemmraum zur Aufnahme der Kamera 8 definieren. Wie den Figuren 1 und 2 zu entnehmen ist, steht der Wärmeleitblock 6 in großflächigem Kontakt mit der oberen Innenwand des Schutzgehäuses 2. Die Kamera 8 ist nicht wie üblich an vorgesehenen Gewindebohrungen verschraubt, sondern mit Hilfe der Spanneinrichtung 4 und des Wärmeleitblocks 6 in das Gehäuse 2 eingeklemmt, wodurch sich einerseits eine höhere Flächenpressung zwischen Kamera 8 und Schutzgehäuse 2 ergibt, und somit eine deutlich besseren Wärmeübergang von der Kamera 8 auf das Schutzgehäuse 2, und andererseits eine größere Freiheit bei der Anordnung der Kamera 8 in dem Schutzgehäuse 2. Die in der Kamera 8 freigesetzte Wärme wird, wie weiter unten noch detaillierter gezeigt, über den Wärmeleitblock 6 in das Schutzgehäuse 2 abgeführt. [0021] Spanneinrichtung 4 und Wärme leitblock 6 sind in der gezeigten Ausführungsform unabhängig voneinander verschieblich in dem Schutzgehäuse 2 angeordnet, indem Spanneinrichtung 4, Kamera 8 und Wärme leitblock 6 durch Anstellung der Keile 4a, 4b der Spanneinrichtung 4 gegen die Innenwände des Schutzgehäuses 2 verklemmt werden. Will man die Verschieblichkeit nicht und legt man Wert auf eine Fixierung der Elemente inner- halb des Schutzgehäuses 2 ist auch ein Verkleben der Elemente denkbar, wie auch eine Ausbildung des Wärmeleitblocks denkbar ist, bei dem dieser über die Kanten des Kameragehäuses hinweggreift.Figures 1 and 2 show in different sectional views the operating principle of the embodiment of the invention. Shown is a protective housing 2, for example an aluminum profile, which can be closed at both ends with glass or metal, with a clamping device 4 made of adjustable wedges 4a and 4b and with a clamping device 4 opposite Wärmeleitblock 6 of hochwärmeleitfähigem material, wherein the Clamping device and the Wärmeleitblock between them define a terminal space for receiving the camera 8. As can be seen from FIGS. 1 and 2, the heat-conducting block 6 is in contact with the upper inner wall of the protective housing 2 over a large area. The camera 8 is not screwed to the provided threaded holes as usual, but with the aid of the clamping device 4 and the heat-conducting block 6 into the housing 2 pinched, resulting in the one hand, a higher surface pressure between the camera 8 and protective housing 2, and thus a much better heat transfer from the camera 8 to the protective housing 2, and on the other hand, a greater freedom in the arrangement of the camera 8 in the protective housing 2. The heat released in the camera 8, as shown in more detail below, discharged via the Wärmeleitblock 6 in the protective housing 2. Tensioning device 4 and heat conducting block 6 are arranged in the embodiment shown independently displaceable in the protective housing 2 by tensioning device 4, camera 8 and heat conductive block 6 by employment of the wedges 4a, 4b of the clamping device 4 clamped against the inner walls of the protective housing 2 become. If one does not want to be displaceable and if one attaches importance to a fixation of the elements within the protective housing 2, it is also conceivable to adhere the elements, just as it is conceivable to form the heat conducting block in which the latter engages over the edges of the camera housing.
[0022] Die Figur 3 zeigt im Grunde denselben seitlichen Querschnitt wie die Figur 1, jedoch in größerem Detail, wobei identische Merkmale auch mit identischen Bezugszei- chen versehen sind. Bei der in Figur 3 dargestellten Ausführungsform ist der Wärme leitblock 6 auf seinen Klemmflächen mit Wärme leitfolien 10 versehen, die eine Anpassung an die Konturen der Kamera 8 und der Innenwand des Schutzgehäuses 2 ermöglichen, so dass eine maximale Wärmeabfuhr sichergestellt ist, die durch den nach oben weisenden Pfeil 12 schematisch dargestellt ist. [0023] In einer nicht dargestellten Variante wird nur eine Wärme leitfolie zwischen Kamera und Wärmeleitblock eingesetzt - hauptsächlich damit die Klemmung der Kamera nur über Kameravorder- und Rückwand erfolgt, und nicht über den druckempfindlichen Mittelteil der Kamera. [0024] Durch Hinzufügen von Wärme leitfolien zwischen Kamera und Klemmblöcken kann auch eine komplette elektrische Isolierung der Kamera vom Gehäuse erreicht werden, ohne die Wärmeableitung zu beeinträchtigen.FIG. 3 basically shows the same lateral cross-section as FIG. 1, but in greater detail, identical features also being provided with identical reference numerals. In the embodiment shown in Figure 3, the heat conducting block 6 on its clamping surfaces with heat conducting films 10 provided that allow adaptation to the contours of the camera 8 and the inner wall of the protective housing 2, so that a maximum heat dissipation is ensured by the after top arrow 12 is shown schematically. In a variant, not shown, only a heat leitfolie between the camera and Wärmeleitblock is used - mainly so that the clamping of the camera takes place only on Kameravorder- and rear wall, and not on the pressure-sensitive middle part of the camera. By adding heat conducting films between the camera and terminal blocks and a complete electrical insulation of the camera can be achieved by the housing, without affecting the heat dissipation.
[0025] Um die Montage zu erleichtern, ist es auch möglich, zwischen Wärmeleitblock und Gehäuse keine Folie vorzusehen, ohne die Wärmeabfuhr wesentlich zu beeinträchtigen, die schon durch den Anpressdruck gewährleistet wird. [0026] Der Figur 3 sind weitere Details der Kamera 8 zu entnehmen, wobei das Gehäuse der Kamera 8 aufgeschnitten dargestellt ist. Innerhalb der Kamera 8 befindet sich eine Schaltplatine 14, auf der ein Mikroprozessor 16 zur Verarbeitung der durch das Objektiv 18 gelieferten Kameradaten vorgesehen ist. Da der Mikroprozessor 16 Wärme erzeugt, die abgeführt werden muss, ist zwischen Prozessor 16 und der Gehäusewand 20 der Kamera 8 ebenfalls ein Wärmeleitblock 22 angeordnet, unter Zwischenschaltung einer weiteren Wärme leitfolie 24, um einen größtmöglichen Wärmeübergang zu gewährleisten. [0027] Durch die vorliegende Erfindung wird somit ein Konzept vorgeschlagen, bei dem die jeweilige Kamera ohne Verwendung der Befestigungs- Gewindebohrungen an Kameras mit Hilfe von Spanntechnik in das Gehäuse geklemmt wird. Durch die Zustellung der Keile oder eine andere geeignete Spanntechnik, wird die Kamera an den "Heatguide" - Wärmeleitblock gedrückt. Dieser Wärmeleitblock wiederum stützt sich an der Gehäusein- nenseite des Schutzgehäuses ab. Der Kraftschluss wird über das Schutzgehäuse geschlossen. In order to facilitate assembly, it is also possible to provide between the heat conducting block and the housing no film without significantly affecting the heat dissipation, which is already ensured by the contact pressure. 3 shows further details of the camera 8, wherein the housing of the camera 8 is shown cut away. Within the camera 8 is a circuit board 14 on which a microprocessor 16 for processing by the lens 18 supplied camera data is provided. Since the microprocessor 16 generates heat that must be dissipated, between the processor 16 and the housing wall 20 of the camera 8 also a heat conducting block 22 is arranged, with the interposition of another heat-conducting film 24 to ensure the greatest possible heat transfer. By the present invention, therefore, a concept is proposed in which the respective camera is clamped without the use of mounting tapped holes on cameras using clamping technology in the housing. By delivering the wedges or other suitable clamping technology, the camera is pressed against the "Heatguide" heat conducting block. This heat conducting block in turn is supported on the inside of the housing of the protective housing. The adhesion is closed via the protective housing.
