Abstract
Description
Die Erfindung betrifft einen Mikrowellensender mit einer Erzeugungseinrichtung zum Erzeugen von Mikrowellen und mit einem Wellenleiter zum Weiterleiten der Mikrowellen. Des Weiteren betrifft die Erfindung ein Verfahren zum Betreiben eines solchen Mikrowellensenders.The invention relates to a microwave transmitter with a generating device for generating microwaves and with a waveguide for transmitting the microwaves. Furthermore, the invention relates to a method for operating such a microwave transmitter.
Aus dem Fahrzeugbau ist es bekannt, Bauteile insbesondere des Rohbaus durch Klebeverbindungen miteinander zu verbinden. Während zum Fügen von metallischen Bauteilen Schweißverfahren wie das Punktschweißen zum Einsatz kommen, versagen diese gängigen Verfahren beim Verbinden von Bauteilen aus faserverstärkten Kunststoffen miteinander. Auch Fügeverfahren, bei welchen Nieten oder – etwa beim Anwenden der Rivtac®-Technologie – Bolzen verwendet werden, bereiten beim Verbinden von Bauteilen aus kohlefaserverstärkten Kunststoffen Probleme, da es zu Kontaktkorrosion kommen kann. Gleichwohl sind diese Fügeverfahren zum Verbinden von Bauteilen aus faserverstärktem Kunststoff mit nicht-leitenden Fasern einsetzbar.From the vehicle industry, it is known to connect components in particular of the shell by adhesive joints with each other. While welding processes such as spot welding are used to join metallic components, these common methods fail to bond together components made of fiber-reinforced plastics. Also joining methods where rivets or - for example when applying the Rivtac ® technology - are used bolts, ready when joining components made of carbon fiber reinforced plastics problems as it may lead to contact corrosion. However, these joining methods for connecting components made of fiber-reinforced plastic with non-conductive fibers can be used.
Zum Fügen von Bauteilen aus kohlefaserverstärktem Kunststoff (CFK) mit weiteren CFK-Bauteilen oder metallischen Bauteilen kommen daher vorzugsweise Klebeverbindungen zum Einsatz. Das Aushärten des Klebstoffs dauert jedoch eine gewisse Zeit. Um sicherzustellen, dass die miteinander zu verbindenden Bauteile während des Aushärtens des Klebstoffs nicht verrutschen, werden die Bauteile während des Aushärtens fixiert. Dies kann beispielsweise durch mechanische Spannvorrichtungen bewerkstelligt werden.For joining components made of carbon fiber reinforced plastic (CFRP) with other CFRP components or metallic components therefore preferably adhesive bonds are used. However, the curing of the adhesive takes a certain amount of time. To ensure that the components to be joined together do not slip during the curing of the adhesive, the components are fixed during curing. This can be done, for example, by mechanical tensioning devices.
Werden im Fahrzeugbau Klebstoffe für Strukturverklebungen eingesetzt, so wird üblicherweise eine verhältnismäßig lange Zeit vorgesehen, während welcher der Klebstoff fließfähig ist, damit zwischen zwei aufeinander folgenden Vorgängen des Auftragens von Klebstoff dieser nicht im Auftragsrohr aushärtet und dadurch das Auftragsrohr verstopft. üblicherweise wird also eine so genannte „Offenzeit” des Klebstoffs von etwa 15 Minuten angestrebt. Anderseits ist es wünschenswert, dass der Klebstoff vergleichsweise rasch aushärtet, sobald die Bauteile gefügt sind, denn dann kann eine durch Verkleben von wenigstens zwei Bauteilen hergestellte Baugruppe rasch und ohne zusätzliche Fixiervorrichtungen transportiert oder weiter bearbeitet werden.If adhesives are used for structural bonding in vehicle construction, a relatively long time is usually provided during which the adhesive is free-flowing, so that it does not harden in the application pipe between two consecutive operations of applying adhesive and thereby clogs the application pipe. Usually, therefore, a so-called "open time" of the adhesive of about 15 minutes is desired. On the other hand, it is desirable that the adhesive hardens comparatively quickly as soon as the components are joined, because then an assembly produced by bonding at least two components can be transported or further processed quickly and without additional fixing devices.
Eine kurze Aushärtungszeit lässt sich beispielsweise durch Verwenden eines Klebstoffs erreichen, welcher durch Einbringen von Wärme in denselben aushärtet. Hierbei wird ein Auftragsrohr, durch welchen der Klebstoff strömt, während des Auftragens des Klebstoffs erwärmt. Dies erfordert jedoch eine sehr genaue Prozessführung, denn wenn der Klebstoff bereits in dem Auftragsrohr aushärtet, dann verstopft dieses und muss ersetzt werden. Dies führt zu erhöhten Kosten und einem erhöhten Reparaturaufwand.A short curing time can be achieved, for example, by using an adhesive which cures by introducing heat into it. In this case, an application tube, through which the adhesive flows, is heated during the application of the adhesive. However, this requires a very precise process management, because if the adhesive already cures in the application tube, then it clogs and must be replaced. This leads to increased costs and increased repair costs.
Die Fixierung von Bauteilen, welche mit Hilfe eines Klebstoffs verbunden werden, der bei Raumtemperatur langsam aushärtet, lässt sich in Bezug auf die Härtezeit des Klebstoffs verkürzen, wenn die Klebebereiche erhitzt werden. Das Einbringen von Heizelementen ist jedoch in schlecht zugänglichen Klebebereichen oftmals nicht möglich. Eine Bestrahlung der Klebstoffschicht mit elektromagnetischen Wellen durch eines der Bauteile hindurch scheitert daran, dass metallische Bauteile und CFK-Bauteile die elektromagnetische Strahlung abschirmen.The fixation of components which are bonded by means of an adhesive that cures slowly at room temperature can be shortened in terms of the curing time of the adhesive when the adhesive areas are heated. However, the introduction of heating elements is often not possible in poorly accessible adhesive areas. Irradiation of the adhesive layer with electromagnetic waves through one of the components fails because metallic components and CFRP components shield the electromagnetic radiation.

Das Einbringen der Wärme in den Klebstoff dient hierbei dazu, die zum Aushärten des Klebstoffs nötige Zeit zu verkürzen. Durch das Aushärten des Klebstoffs werden die Bauteile relativ zueinander fixiert, sodass mechanische Spannvorrichtungen die vor dem Aushärten des Klebstoffs für die Fixierung sorgen, entfernt werden können.The introduction of heat into the adhesive serves to shorten the time required to cure the adhesive. By curing the adhesive, the components are fixed relative to each other, so that mechanical tensioning devices that provide for the fixation prior to curing of the adhesive can be removed.
Das Einbringen von Heizwärme in die Klebstoffschicht mittels des Induktors setzt jedoch voraus, dass die Klebstoffschicht gut zugänglich ist. However, the introduction of thermal heat in the adhesive layer by means of the inductor requires that the adhesive layer is easily accessible.
Aufgabe der vorliegenden Erfindung ist es, einen Mikrowellensender und ein Verfahren der eingangs genannten Art zu schaffen, welcher bzw. welches ein besonders prozesssicheres Fixieren von Bauteilen ermöglicht.Object of the present invention is to provide a microwave transmitter and a method of the type mentioned, which or which allows a particularly process-reliable fixing of components.
Diese Aufgabe wird durch einen Mikrowellensender mit den Merkmalen des Patentanspruchs 1 und durch ein Verfahren mit den Merkmalen des Patentanspruchs 9 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.This object is achieved by a microwave transmitter having the features of patent claim 1 and by a method having the features of patent claim 9. Advantageous embodiments with expedient developments of the invention are specified in the dependent claims.
Bei dem erfindungsgemäßen Mikrowellensender ist eine Auslassöffnung der Auslasseinrichtung zumindest bereichsweise von Abschirmelementen umgeben. Die Abschirmelemente dienen dazu, im Betrieb des Mikrowellensenders eine Beaufschlagung einer Umgebung der Auslasseinrichtung mit den Mikrowellen zu verringern. So lässt sich sehr leicht sicherstellen, dass gesetzlich, etwa im deutschen Bundesemissionsschutzgesetz, definierte Strahlungsgrenzwerte eingehalten werden. Zudem lässt sich der Klebstoff so besonders prozesssicher erwärmen, da dem Schutz von Personen vor Mikrowellen Rechnung getragen ist.In the case of the microwave transmitter according to the invention, an outlet opening of the outlet device is surrounded by shielding elements at least in regions. The shielding serve to reduce the operation of the microwave transmitter, an exposure of an environment of the outlet with the microwaves. This makes it very easy to ensure that legally defined radiation limits are adhered to, for example in the German Federal Emission Control Act. In addition, the adhesive can be heated so particularly process-reliable, since the protection of persons from microwaves is taken into account.
Durch die Abschirmelemente, welche die Auslassöffnung umgeben, ist die Abschirmung der elektromagnetischen Mikrowellen zudem bei geringem Platzbedarf und geringem Materialeinsatz erreichbar. Zugleich bleibt eine gute Zugänglichkeit zu den miteinander zu verklebenden Bauteilen erhalten. Zudem brauchen in der Produktion keine Schleusen oder Tore vorgesehen zu werden, so dass die Logistik vereinfacht ist. Auch lassen sich so Kosten reduzieren.Due to the shielding elements which surround the outlet opening, the shielding of the electromagnetic microwaves can also be achieved with a small space requirement and a low use of material. At the same time, good accessibility to the components to be bonded together is maintained. In addition, no locks or gates need to be provided in the production, so that the logistics is simplified. It also reduces costs.
Die Abschirmelemente sind bevorzugt als metallische Kontaktfedern ausgebildet, welche beim Beaufschlagen der Klebstoffschicht mit den Mikrowellen mit zumindest einem der Bauteile in Anlage bringbar sind. So kann besonders sicher vermieden werden, dass aus einem Zwischenraum zwischen der Auslassöffnung und den Bauteilen Mikrowellen in die Umgebung gelangen können.The shielding elements are preferably designed as metallic contact springs, which can be brought into contact with the microwaves with at least one of the components when the adhesive layer is applied. Thus, it can be particularly reliably avoided that microwaves can escape into the environment from an intermediate space between the outlet opening and the components.
Als für die Abschirmung besonders gut geeignetes Material hat sich eine Kupfer-Beryllium-Legierung erwiesen, aus welcher die Kontaktfedern gebildet sein können.As the shielding particularly well suited material, a copper-beryllium alloy has proven, from which the contact springs can be formed.
Eine besonders einfache Abschirmung lässt sich erreichen, wenn die Abschirmelemente an im Betrieb des Mikrowellensenders den Bauteilen zugewandten Stirnseiten von Wänden eines Käfigs angeordnet sind, wobei die Wände des Käfigs von der Auslassöffnung beabstandet sind. So kann insbesondere die Auslassöffnung zu allen Richtungen hin abgeschirmt werden. Zudem lässt sich ein bestehender Mikrowellensender mit einem solchen Käfig besonders einfach nachrüsten.A particularly simple shielding can be achieved if the shielding elements are arranged on front sides of walls of a cage facing the components during operation of the microwave transmitter, the walls of the cage being spaced from the outlet opening. In particular, the outlet opening can be shielded in all directions. In addition, an existing microwave transmitter with such a cage can be retrofitted very easily.
Die Wände des Käfigs können aus einem gelochten Blech oder aus einem Metallgitter gebildet sein, so dass auch diese zur Abschirmung der Mikrowellen beitragen.The walls of the cage may be formed of a perforated plate or of a metal grid, so that they also contribute to the shielding of the microwaves.
Wenn gemäß einer weiteren vorteilhaften Ausgestaltung der Käfig eine Höhe von 40 Millimetern bis 60 Millimetern und eine Breite von 130 Millimetern bis 170 Millimetern aufweist, ist weiterhin eine gute Zugänglichkeit zu der Klebstoffschicht gegeben, und es lassen sich durch die Auslasseinrichtung vergleichsweise schmale Klebstoffschichten oder Klebenähte gut von der Seite her erreichen. Dies gilt insbesondere, wenn der Käfig eine Höhe von etwa 50 Millimetern und eine Breite von etwa 150 Millimetern aufweist.If, according to a further advantageous embodiment, the cage has a height of 40 millimeters to 60 millimeters and a width of 130 millimeters to 170 millimeters, good accessibility to the adhesive layer is still provided, and comparatively narrow adhesive layers or adhesive seams can be made good by the outlet device reach from the side. This is especially true when the cage has a height of about 50 millimeters and a width of about 150 millimeters.
Zusätzlich oder alternativ können die Abschirmelemente an der Auslasseinrichtung angeordnet sein. Dadurch ist der für die Abschirmung vorzusehende Platzbedarf besonders gering. Zudem lässt sich so eine Effizienzsteigerung des Mikrowellensenders erreichen, da die Abschirmelemente dann zur Fokussierung der Mikrowellen beitragen. Eine Effizienzsteigerung lässt sich hierbei auch im Hinblick auf die eingesetzte Wärmemenge beobachten, da besonders wenig Wärme zur Umgebung der Auslasseinrichtung hin verloren geht und entsprechend viel Wärme in die Klebstoffschicht eingebracht werden kann.Additionally or alternatively, the shielding elements can be arranged on the outlet device. As a result, the space required for the shield space is particularly low. In addition, an increase in efficiency of the microwave transmitter can be achieved, since the shielding elements then contribute to the focusing of the microwaves. An increase in efficiency can also be observed with regard to the amount of heat used, since particularly little heat is lost to the surroundings of the outlet device and correspondingly much heat can be introduced into the adhesive layer.
Die Auslassöffnung kann durch vier Wände der Auslasseinrichtung begrenzt und im Querschnitt rechteckig ausgebildet sein. Die Abschirmelemente sind dann bevorzugt zumindest an den beiden längeren Wänden der Auslasseinrichtung angeordnet. So ist eine Abstrahlung von Mikrowellen in die Richtungen vermieden, in welche es ohne das Vorsehen der Abschirmelemente zu einem verstärkten Abstrahlen von Mikrowellen in die Umgebung kommen könnte.The outlet opening may be delimited by four walls of the outlet device and be rectangular in cross-section. The shielding elements are then preferably arranged at least on the two longer walls of the outlet device. Thus, a radiation of microwaves in the directions is avoided, in which it could come without the provision of the shielding to an increased radiation of microwaves into the environment.
Ein besonders geringer Platzbedarf lässt sich erreichen, wenn ein von den Abschirmelementen eingefasster Bereich in Höhe von 10 Millimetern bis 20 Millimetern und eine Breite von 90 Millimetern bis 100 Millimetern aufweist. So lassen sich besonders gut schmale Klebstoffschichten über eine vergleichsweise große Länge hinweg mit durch die Mikrowellen erzeugter Wärme beaufschlagen. Dies gilt insbesondere, wenn der Bereich eine Höhe von 15 Millimetern und eine Breite von 95 Millimetern aufweist.A particularly small space requirement can be achieved if an area enclosed by the shielding elements in the amount of 10 millimeters to 20 millimeters and a width of 90 millimeters to 100 millimeters. Thus, it is particularly easy to apply narrow layers of adhesive over a comparatively long length to heat generated by the microwaves. This is especially true when the area has a height of 15 millimeters and a width of 95 millimeters.
Bei dem erfindungsgemäßen Verfahren zum Betreiben eines Mikrowellensenders werden mittels einer Erzeugungseinrichtung des Mikrowellensenders Mikrowellen erzeugt. Die Mikrowellen werden durch einen Wellenleiter des Mikrowellensenders hindurch weitergeleitet. Über eine an dem Wellenleiter angeordnete Auslasseinrichtung mit einer Auslassöffnung werden die Mikrowellen abgegeben. Mittels der Mikrowellen wird eine Klebstoffschicht erwärmt, welche zwischen einander zugewandten Oberflächen eines ersten Bauteils und eines zweiten Bauteils angeordnet ist. Hierbei wird eine Beaufschlagung einer Umgebung der Auslasseinrichtung mit den Mikrowellen durch Abschirmelemente verringert, welche die Auslassöffnung der Auslasseinrichtung zumindest bereichsweise umgeben. In the method according to the invention for operating a microwave transmitter, microwaves are generated by means of a generating device of the microwave transmitter. The microwaves are passed through a waveguide of the microwave transmitter. About a arranged on the waveguide outlet with an outlet opening the microwaves are emitted. By means of the microwaves, an adhesive layer is heated, which is arranged between mutually facing surfaces of a first component and a second component. In this case, an exposure of an environment of the outlet device to the microwaves is reduced by shielding elements which surround the outlet opening of the outlet device at least in regions.
So lässt sich eine für eine Bedienperson des Mikrowellensenders besonders sichere Beaufschlagung der Klebstoffschicht mit den Mikrowellen erreichen.This makes it possible to achieve a particularly reliable admission of the adhesive layer to the microwaves to an operator of the microwave transmitter.
