Definitions
- the invention relates to a device for radiation treatment of a coating of an object, in particular for curing paint, with a radiation source and with at least one optical element for supplying radiation from the radiation source to the object.
- a device of the type mentioned is known from DE 10 2004 023 539 A1.
- the device has a conveyor system for vehicle bodies. It contains a portal scaffold that carries several UV light sources.
- the radiation sources for UV light are designed as radiators.
- the radiators include a rod-shaped light source and a reflector.
- the rod-shaped light source in a radiator is positioned in front of the reflector of the radiator.
- the reflector acts as an optical element which redirects the UV light radiated backwards in the opposite direction.
- paint-coated vehicle bodies can be moved past the radiation sources by the portal frame.
- the paint on the vehicle bodies is cured in the radiation field of the radiator.
- the radiators can be moved on the portal frame.
- Paints that can be cured by UV light usually contain so-called photoinitiators. These photoinitiators are transformed into radicals by the UV light acting on the paint. These radicals cause a chemical reaction in the paint. In this reaction, polymer chains of the binder are broken. This creates a netting, which leads to a high strength of the paint layer and in particular causes a high scratch resistance of the surface of the paint layer.
- the desired crosslinking in acrylate systems is particularly well when the radiation is provided in a process window with a defined dose.
- a radiation field with UV light which is present with the correct intensity over a certain period of time, is produced on the lacquer layer.
- a preferred minimum exposure time for an acrylate system is about 1 s. If lacquers are cured incompletely on the basis of acrylate systems, this leads to the so-called “fogging", where solvents are released from the lacquer for a long period of time, and the lacquer coating is less scratch-resistant cause.
- gas discharge lamps such as B. medium pressure mercury vapor lamps, high pressure mercury vapor lamps, metal halide and black light fluorescent lamps.
- gas discharge lamps without electrodes which are ignited by microwaves. Such lamps have an elongated glass bulb in which an arc is generated.
- the glass bulb, the powerful gas discharge lamps used for curing varnish, is about 40 cm long.
- the gas discharge lamps are operated at a voltage of about 400 V and a lamp current of about 10 A.
- the favorable operating temperature of such lamps is in the range between 600 ° C and 900 ° C. In order to be able to comply with this operating temperature, the lamps are cooled.
- the energy supply and the required cooling of the lamps has the consequence that in a movable arrangement of the lamps a high technical complexity must be driven.
- the lamps are arranged in a receiving device in the form of emitters, as described in DE 10 2004 023 539 A1 , DE 10 2004 023 539 A1 is hereby incorporated by reference in its entirety.
- a radiator includes a reflector.
- the distance between the radiator and the lacquer layer is set to a value of approximately 10 cm ⁇ 5 cm in order to obtain a corresponding radiation intensity. Due to the spatial extent of the radiator, it is not yet possible, the paint on winding, hard to reach areas on the body of motor vehicles, such as the only accessible via the trunk Kardantunnel in sedans on the longitudinal members of motor vehicles in the fender on reliably cure the inside of doors and door hinges with UV light. The required small distance between the lacquer layer and the radiator can furthermore lead to condensate being precipitated on cooling devices of the radiator, which drips onto the lacquer layer treated by means of radiation and damages the latter.
- the object of the invention is to provide a device for radiation treatment of a coating of an object, by means of which a radiation field can be generated with high-intensity UV radiation, in particular on winding, hard to reach surfaces.
- a device for radiation treatment of the type mentioned in which the at least one optical element is accommodated on a handling device, by means of which for adjusting the optical path from the radiation source to the object, the optical element relative to the radiation source and relative to the Object is relocatable.
- an idea of the invention is to receive the at least one optical element on a handling device in such a way that it can be moved relative to a holding device for the radiation source with multiple degrees of freedom of movement.
- Suitable sources of radiation according to the invention are preferably: UV emitters, IR emitters, X-ray emitters and / or emitters which emit visible light. animals.
- the emitted radiation may comprise a narrowband or even a broadband wavelength spectrum.
- the radiation sources can contain a thermal radiator or can also be implemented with a laser light source or a gas discharge lamp.
- the invention is based on the finding that a handling device for receiving an optical element, with which radiation from a radiation source can be supplied to an object, has to meet lower mechanical requirements and can be constructed more simply than a movable holding device for the radiation source.
- a radiation source in contrast to a radiation source, in a variant for such an optical element no cooling device is provided.
- an industrial robot as the handling device for the optical element, which has at least two, preferably three, four, five, six or even more axes of movement.
- a handling device in particular, an industrial robot with rotational and / or translational movement axes and a precise and easily controllable serial kinematic is suitable.
- the optical element can, for. B. be designed as a radiation-reflecting reflector with adjustable reflector geometry.
- the optical element can also be formed with a lens. It can, for. B. contain a collection lens or have a Fresnel lens.
- the optical element may comprise an adjustable mirror array.
- an optical element is also a mirror, which preferably has an existing mirror layer of aluminum. Such a mirror is comparatively inexpensive to produce.
- Such a mirror can be manufactured with excellent reflection properties for UV light in the wavelength range between 50 nm and 400 nm by vapor deposition of metallic layers.
- a mirror with at least one dichroic mirror layer is suitable. Due to the wavelength-selective reflection properties of such a dichroic mirror, the wavelength spectrum of the radiation directed to the object can thus be optimized for the radiation treatment of the coating.
- a dichroic mirror whose reflectivity for UV light is preferably in a wavelength range between 200 nm and 400 nm and the light with a wavelength greater than 800 nm, ie infrared radiation, only weakly reflected. This makes it possible to avoid unwanted heating of a radiation-treated coating.
- One finding of the invention is that, for the radiation treatment of uneven paint surfaces with UV light, the paint on the surface of an object can be cured particularly efficiently by means of an optical element in the form of a reflector which diffusely reflects the radiation.
- reflectors with a reflector layer made of Teflon are suitable for the diffuse scattering of UV light.
- a reflector layer made of Teflon
- Teflon is physically and chemically unstable at the operating temperature of gas discharge lamps in UV radiation generators, which is preferably in a range between 600 ° C and 900 ° C. Therefore, no reflector with Teflon layer can be used inside such radiator. Since a reflector accommodated on a handling device can be moved with a corresponding distance from a UV light emitter, the invention makes it possible, in particular, for Teflon-containing optical elements to be used for the radiation treatment of surfaces with UV light in order to reduce the UV light to harden a coating to an object surface.
- the handling device is designed for the automatic replacement of the optical element received on it. This makes it possible to adapt the device for radiation treatment to objects with different surface geometry.
- the radiation source in a reflector with a reflector, which generates directed radiation, which is supplied to the optical element.
- the emitter may in particular comprise an optical assembly having at least one converging lens and / or a Fresnel lens.
- a reflector in the form of a concave mirror which, for producing a directional radiation field, has a reflection surface with concave cross-section. ometrie has.
- the geometry of the reflection surface is designed such that the radiation flux density of the radiation emitted by the radiation source is maximized in a plane spaced from the outlet opening of the concave mirror. Conveniently, this distance is a multiple of the diameter of the outlet opening, in particular the two, five, ten or even twenty times the diameter.
- a reflector can be provided in the radiator, which has an adjustable reflector geometry. A particularly large variability of the radiation field on the object is achieved by the spotlight being accommodated on a holding device that can be adjusted by means of drives.
- This holding device can be designed, for example, as an industrial robot, preferably as an industrial robot, which has at least two, in particular three, four, five, six or even more axes of movement.
- an industrial robot with rotary and translatory axes of motion and serial kinematics is suitable as a receptacle for the radiation source.
- absorption and scattering losses for the radiation between the radiation source and the object can be minimized.
- this allows a greater distance between the radiation source and the object, since then the UV radiation experiences lower intensity losses even with a long optical path between the radiation source and the object surface.
