Description
Vorrichtung zur Tauchlackierung eines Karosserieteils Device for dip painting a body part
B e s c h r e i b u n gDescription
Die Erfindung betrifft eine Vorrichtung zur Tauchlackierung eines Karosserieteils eines Kraftfahrzeu- ges mit einem Becken zur Aufnahme einer Beschichtungs- flüssigkeit, mit einer Transporteinrichtung zum Transport des Karosserieteils durch das Becken, mit einer Gleichstromquelle, mit einem mit der Anode der Gleichstromquelle verbundenen Anodenkörper und mit einer, mit der Katho- de der Gleichstromquelle verbundenen Führung zur elektrischen Kontaktierung und Bewegung des Karosserieteils durch das Becken.The invention relates to a device for dip painting a body part of a motor vehicle with a tank for receiving a coating liquid, with a transport device for transporting the body part through the pool, with a DC source, with an anode body connected to the anode of the DC source and with a , Guidance connected to the cathode of the DC power source for electrical contacting and movement of the body part through the pool.
Solche Vorrichtungen werden zur Tauchlackierung von Fahrzeugkarosserien, wie einzelnen Karosserieteilen, beispielsweise einer Fahrzeugtür oder vollständigen Rohkarossen häufig eingesetzt und sind beispielsweise aus der DE 196 06 000 Cl bekannt. Bei dieser Vorrichtung sind mehrere Anodenkörper in dem Becken angeordnet und werden von unterschiedlichen Gleichstromquellen mit elektrischem Strom versorgt. Beim Durchführen des Karosserieteils durch das Becken entsteht ein Gleichspannungsfeld zwischen den Anoden und der Oberfläche des Karosserieteils. Das Karosserieteil zieht Dispersionsteilchen aus der Be- Schichtungsflüssigkeit an. Die Beschichtungsflüssigkeit , welche beispielsweise eine wässrige Dispersion eines Ein- brennlacks sein kann, lagert sich als Schicht auf dem Karosserieteil ab.Such devices are often used for dip painting of vehicle bodies, such as individual body parts, such as a vehicle door or full bodyshells and are known for example from DE 196 06 000 Cl. In this device, a plurality of anode bodies are arranged in the basin and are supplied with electric current from different DC sources. As the bodywork passes through the pool, a DC field is created between the anodes and the surface of the body panel. The body part attracts dispersion particles from the coating fluid. The coating liquid which comprises, for example, an aqueous dispersion of a Burning lacquer can be deposited as a layer on the body part.
Die Schichtbildung auf dem Karosserieteil hängt neben der Eintauchzeit, der Badtemperatur und der Zusammensetzung der Beschichtungsflüssigkeit auch von der Stärke und Verteilung des elektrischen Gleichstromfeldes ab. Die Schichtdicke soll zumindest >= 20μm auf der Außenseite und >= lOμm innerhalb von Hohlräumen des Karos- serieteils betragen. Die Anordnung von feststehenden Anoden führt jedoch dazu, dass sich auf der Außenseite des Karosserieteils eine besonders starke Schicht und innerhalb der Hohlräume eine besonders geringe Schicht ablagert. Dies führt zu einer unerwünschten hohen Schichtdi- cke auf der Außenseite und einer unerwünscht niedrigenThe layer formation on the body part depends not only on the immersion time, the bath temperature and the composition of the coating liquid but also on the strength and distribution of the DC electric field. The layer thickness should be at least> = 20 μm on the outside and> = 10 μm within cavities of the body part. The arrangement of fixed anodes, however, leads to the deposition of a particularly thick layer on the outside of the body part and a particularly small layer inside the cavities. This leads to an undesirably high layer thickness on the outside and an undesirably low one
Schichtdicke innerhalb der Hohlräume des Karosserieteils.Layer thickness within the cavities of the body part.
Zur Erzielung einer möglichst präzisen Be- schichtung ist es aus der DE 103 26 605 Al bekannt, meh- rere Anoden über das Becken verteilt anzuordnen und einzeln mit einer vorgesehenen Strom-/Spannungskennlinie entsprechend der Kontur des Karosserieteils anzusteuern. Dies führt jedoch zu einem sehr hohen Steuerungsaufwand.In order to achieve a coating that is as precise as possible, it is known from DE 103 26 605 A1 to arrange a plurality of anodes distributed over the basin and to actuate them individually with an intended current / voltage characteristic in accordance with the contour of the body part. However, this leads to a very high control effort.
Aus der JP 5 800 3996A ist eine Vorrichtung mit einem beweglichen Anodenkörper bekannt geworden. Der Anodenkörper ist seitlich neben dem Karosserieteil angeordnet. Auch bei dieser Vorrichtung lässt in sich von dem Anodenkörper entfernten Bereichen des Karosserieteils nur eine geringe Schichtdicke abscheiden.From JP 5 800 3996 A a device with a movable anode body has become known. The anode body is arranged laterally next to the body part. In this device, too, only a small layer thickness can be deposited in regions of the body part remote from the anode body.
Der Erfindung liegt das Problem zugrunde, eine Vorrichtung der eingangs genannten Art so weiter zu bilden, dass mit ihr die Schichtdicke an jeder Stelle des Karosserieteils möglichst einfach festgelegt werden kann. Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Anodenkörper in einer konstanten Position zu dem Karosserieteil in Bewegungsrichtung des Karosserieteils vor und/oder hinter dem Karosserieteil montier- bar und mit dem Karosserieteil durch das Becken führbar ist.The invention is based on the problem of further developing a device of the type mentioned above so that the layer thickness at each point of the body part can be determined as simply as possible with it. This problem is inventively solved in that the anode body in a constant position to the body part in the direction of movement of the body part in front of and / or behind the body part can be mounted bar and with the body part through the tank is feasible.
Durch diese Gestaltung lassen sich der Anodenkörper und das Karosserieteil hintereinander durch das Bad führen. Dies bewirkt eine hohe und gleichmäßige Feldliniendichte und bei entsprechender Wahl der Anordnung des mit dem Karosserieteil führbaren Anodenkörpers eine Feldstärkepenetration über den gesamten Schichtbildungs- prozess an den Bereichen des Karosserieteils, die mit ortsfesten oder seitlich neben dem Karosserieteil mitbewegten Anodenkörpern nicht oder nur unzureichend erreicht werden. Durch die Position und Ausrichtung des Anodenkörpers zu dem Karosserieteil lässt sich die Stärke und die Verteilung des Gleichstromfeldes zwischen dem Anodenkör- per und dem Karosserieteil weitgehend frei festlegen. Da die Stärke und die Verteilung des Gleichstromfeldes maßgeblich die abgelagerte Schichtdicke beeinflussen, lässt sich dank der Erfindung die Schichtdicke an jeder Stelle des Karosserieteils einfach festlegen. Damit lässt sich eine unerwünscht hohe Ablagerung an seitlichen Bereichen des Karosserieteils vermeiden und gleichzeitig eine ausreichende Ablagerung an verdeckten Bereichen des Karosserieteils sicherstellen. Die erfindungsgemäße Vorrichtung vermeidet einen hohen Steuerungsaufwand und lässt sich daher besonders einfach anwenden. Selbstverständlich kann diese Vorrichtung bei Umkehr der Polung der Gleichstromquelle mit mitlaufenden Kathodenkörpern in einem anodischen Verfahren eingesetzt werden.With this design, the anode body and the body part can be consecutively pass through the bathroom. This causes a high and uniform field line density and, with a suitable choice of the arrangement of the anode body can be guided with the body field penetration over the entire Schichtbildungs- process at the areas of the body part, which are not or only insufficiently achieved with stationary or laterally moving along with the body part anode bodies. Due to the position and orientation of the anode body to the body part, the strength and distribution of the DC field between the anode body and the body part can be determined largely free. Since the thickness and distribution of the DC field significantly affect the deposited layer thickness, the layer thickness can be easily determined at any point of the body part thanks to the invention. This makes it possible to avoid an undesirably high deposit on lateral areas of the body part and at the same time to ensure sufficient deposit on hidden areas of the body part. The device according to the invention avoids a high control effort and can therefore be used particularly easily. Of course, this device can be used in reversing the polarity of the DC power source with rotating cathode bodies in an anodic process.
Eine bevorzugte Ablagerung von Dispersionsteilchen der Beschichtungsflüssigkeit in einem Hohlraum des Karosserieteils lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung erreichen, wenn der mit dem Karosserieteil durch das Becken führbare Anodenkörper vor einer Öffnung eines Hohlraums des Karosserie- teils angeordnet ist.A preferred deposition of dispersion particles of the coating liquid in a cavity of the Body part can be achieved according to another advantageous embodiment of the invention, when the feasible with the body part through the tank anode body is arranged in front of an opening of a cavity of the body part.
Die erfindungsgemäße Vorrichtung gestaltet sich konstruktiv besonders einfach, wenn eine weitere, mit der Anode der Gleichstromquelle verbundene Führung vorgesehen ist und wenn der mit dem Karosserieteil durch das Becken führbare Anodenkörper an der weiteren Führung geführt ist. Vorzugsweise sind die Führungen als Stromschienen ausgebildet, in die das Karosserieteil und der Anodenkörper mittelbar eingehängt werden.The device according to the invention is structurally particularly simple if another, connected to the anode of the DC power supply guide is provided and if the feasible with the body part through the tank anode body is guided on the other guide. Preferably, the guides are designed as busbars, in which the body part and the anode body are suspended indirectly.
Zur weiteren Vereinfachung des konstruktiven Aufbaus der erfindungsgemäßen Vorrichtung trägt es bei, wenn die beiden Führungen parallel zueinander angeordnet sind und jeweils einen Haltearm zur Halterung des mit dem Karosserieteil durch das Becken führbaren Anodenkörpers oder des Karosserieteils aufweisen. Durch diese Gestaltung lassen sich die Führungen außerhalb des Beckens anordnen. Die Haltearme stellen damit die Verbindungen der außerhalb des Beckens angeordneten Führungen mit dem innerhalb des Beckens angeordneten Anodenkörper und dem Karosserieteil her.To further simplify the structural design of the device according to the invention, it is helpful if the two guides are arranged parallel to one another and each have a holding arm for holding the anode body which can be guided through the basin with the body part or the body part. Through this design, the guides can be arranged outside the basin. The support arms thus make the connections of the outside of the basin arranged guides with the arranged inside the basin anode body and the body part.
Eine besonders gleichmäßige Ablagerung von Dispersionsteilchen der Beschichtungsflüssigkeit auf dem Ka- rosserieteil lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach erreichen, wenn der mit dem Karosserieteil durch das Becken führbare Anodenkörper lang gestreckt gestaltet ist. Der lang gestreckte Anodenkörper ist vorzugsweise parallel zu ebenfalls lang gestreckten Karosserieteilen oder vor einer lang gestreckten Öffnung im Karosserieteil angeordnet. An verschiedenen Stellen des Karosserieteils lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung vorgesehene Schichtdicken erzeugen, wenn mehrere, mit dem Karosserieteil durch das Becken führbare Anodenkörper um das Karosserieteil herum gruppiert sind. Vorzugsweise ist zu beiden Seiten des Karosserieteils jeweils ein mit dem Karosserieteil durch das Becken führbarer Anodenkörper montiert.A particularly uniform deposition of dispersion particles of the coating liquid on the body part can be easily achieved according to another advantageous embodiment of the invention, when the anode body which can be guided through the tank with the body part is designed to be elongated. The elongate anode body is preferably arranged parallel to likewise elongated body parts or in front of an elongated opening in the body part. At different locations of the body part, layer thicknesses provided according to another advantageous development of the invention can be produced when a plurality of anode bodies which can be guided through the tank by the body part are grouped around the body part. Preferably, an anode body which can be guided through the basin with the body part is mounted on both sides of the body part.
Zur Vergleichmäßigung der abgeschiedenenTo equalize the deposited
Schichtdicken trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn in dem Becken zumindest ein weiterer, mit der Anode der Gleichspannungs- quelle verbundener, feststehender Anodenkörper angeordnet ist. Durch diese Gestaltung bilden sowohl der zumindest eine unbeweglich in dem Becken angeordnete Anodenkörper als auch der oder die mit dem Karosserieteil durch das Becken führbare Anodenkörper jeweils ein Gleichstromfeld mit dem Karosserieteil. Damit werden sprungartige Unterschiede der auf dem Karosserieteil abgelagerten Schichtdicken zuverlässig vermieden.Layer thickness contributes according to another advantageous embodiment of the invention, if in the basin at least one further, connected to the anode of the DC voltage source, fixed anode body is arranged. As a result of this configuration, both the at least one anode body arranged immovably in the basin and the one or more anode bodies which can be guided through the pool with the body part form a DC field with the body part. This reliably prevents sudden differences in the layer thicknesses deposited on the body part.

Die Vorrichtung hat ein Becken 2 zur Aufnahme einer Beschichtungsflüssigkeit 3 und des Karosserieteils 1. Weiterhin sind in dem Becken 2 mehrere Anodenkörper 4 angeordnet. Das Karosserieteil 1 ist elektrisch leitend mit einer Kathode (-) einer Gleichstromquelle 7 verbunden. Die Anodenkörper 4 - 6 sind mit der Anode (+) der Gleichstromquelle 7 verbunden.Line II - II. FIG. 1 schematically shows a device for dip-coating a body part 1 designed as a vehicle door of a motor vehicle. The device has a tank 2 for receiving a coating liquid 3 and the body part 1. Furthermore, a plurality of anode bodies 4 are arranged in the tank 2. The body part 1 is electrically conductively connected to a cathode (-) of a DC power source 7. The anode bodies 4 - 6 are connected to the anode (+) of the DC power source 7.
Zwei der Anodenkörper 4, 5 sind feststehend in dem Becken 2 angeordnet, während einer der Anodenkörper 6 mit dem Karosserieteil 1 beweglich durch das Becken 2 führbar ist. Das Karosserieteil 1 und der mit dem Karosserieteil 1 durch das Becken 2 führbare Anodenkörper 6 sind jeweils an einem Haltearm 8, 9 angeordnet und in einer Führung 10, 11 längsverschieblich geführt. Die Führungsrichtung erfolgt senkrecht zur Zeichenebene. Damit sind das Karosserieteil und der mit dem Karosserieteil 1 durch das Becken 2 führbare Anodenkörper 6 in Bewegungsrichtung gesehen hintereinander angeordnet. Über Elektromotoren 12, 13 lassen sich der mit dem Karosserieteil 1 durch das Becken 2 führbare Anodenkörper 6 und das Karos- serieteil 1 gleichzeitig aus dem Becken 2 herausbewegen und in dieses hineinführen. Durch gleichzeitige Ansteuerung der Elektromotoren 12, 13 wird der Abstand und die Position des mit dem Karosserieteil 1 durch das Becken 2 führbaren Anodenkörpers 6 zu dem Karosserieteil 1 kons- tant gehalten. Der mit dem Karosserieteil 1 durch das Becken 2 führbare Anodenkörper 6 ist lang gestreckt gestaltet und parallel zur längsten Erstreckung des Karosserieteils 1 angeordnet. Die Führung 10 für das Karosserieteil 1 und der daran angeschlossene Elektromotor 12 bilden ei- ne Transporteinrichtung zur Führung des Karosserieteils 1 durch das Becken 2. Figur 2 zeigt in einem Teilschnitt durch die Vorrichtung aus Figur 1 entlang der Linie II - II, dass insgesamt zwei mit dem Karosserieteil 1 durch das Becken 2 führbare Anodenkörper 6, 6' zu beiden Seiten des Karosserieteils 1 angeordnet sind. Die beweglich geführten Anodenkörper 6, 6' sind nahe an einem Hohlraum 14 des Karosserieteils 1 angeordnet. Der Hohlraum 14 des in dem dargestellten Ausführungsbeispiel dargestellten Karosse- rieteils 1 hat eine einem der geführten Anodenkörper 6 zugewandte Öffnung 15. Two of the anode body 4, 5 are fixedly arranged in the basin 2, while one of the anode body 6 with the body part 1 is movable through the tank 2 feasible. The bodywork part 1 and the anode body 6, which can be guided by the body 2 with the bodywork part 1, are each arranged on a holding arm 8, 9 and guided longitudinally displaceably in a guide 10, 11. The guiding direction is perpendicular to the drawing plane. Thus, the body part and the feasible with the body part 1 through the tank 2 anode body 6 are arranged seen in the direction of movement one behind the other. By means of electric motors 12, 13, the anode body 6, which can be guided through the basin 2 with the body part 1, and the body part 1 can simultaneously be moved out of the basin 2 and led into it. By simultaneous control of the electric motors 12, 13, the distance and the position of the anode body 6, which can be guided through the basin 2 with the bodywork part 1, are kept constant relative to the bodywork part 1. The anode body 6, which can be guided through the basin 2 with the bodywork part 1, is of elongated design and arranged parallel to the longest extension of the body part 1. The guide 10 for the body part 1 and the electric motor 12 connected thereto form a transport device for guiding the body part 1 through the basin 2. FIG. 2 shows, in a partial section through the device from FIG. 1 along the line II-II, that a total of two anode bodies 6, 6 'which can be guided through the basin 2 with the bodywork part 1 are arranged on both sides of the bodywork part 1.
