Description

The invention relates to a processing system for at least partially removing a coating arranged on a component, such as vehicle component or operating means, with at least one processing unit, through which at least one surface region of the component can be exposed to a processing beam emerging from a processing head of the processing unit and at least one part of the coating is thermally destructible in the surface area, and with at least one suction unit, are sucked through, in particular in the thermal destruction of the coating resulting, gases and suspended particles, and a method for operating such a processing plant.

Components are usually made of metallic materials, such as steel, aluminum or magnesium. These are provided with a coating which may comprise one or more layers. The coating serves as corrosion protection for the metallic materials and often also serves to improve the aesthetic effect of the components or arises process-related in the equipment.

For components, there may be a need to remove the coating on certain surface areas or in its entirety. For this purpose, the coating is removed in the above-mentioned processing equipment by a processing unit by means of laser beam.

A generic processing plant is known from DE 10 2017 112 072 A1 in which components can be arranged under a rigidly and immovably arranged processing unit. The components are moved in the known processing plant relative to this.

An object of an embodiment of the invention is to propose an alternative expedient design of a processing plant.

This object is achieved by a processing plant mentioned above, which comprises at least one manipulator, such as robots, which is multi-axially formed and / or has a kinematics comprising several degrees of freedom and on which at least the processing head of the processing unit can be arranged or arranged.

Because the processing system has a multi-axis manipulator or a manipulator with a kinematics comprising several degrees of freedom, on which at least the machining head of the machining unit can be arranged, the machining head can be arranged easily at different heights and locations of the component as well as in different angular positions, in particular angles of incidence the surface areas of the component adjustable, whereby a processing of the surface areas of the component is facilitated. In that case, the component can be held rigidly and immovably and the machining head can be moved relative to the component by the manipulator.

The component may include, for example, a vehicle component or a resource.

The manipulator may, for example, comprise a robot, in particular an industrial robot.

The processing beam can be any electromagnetic wave in which electromagnetic radiation leads to heating of the coating. The electromagnetic radiation may in particular comprise light in the spectrum of laser light. As a result, a thermal destruction of the coating can be realized in a simple manner.

It proves to be advantageous if the machining head comprises at least one releasably or non-detachably fixed machining optics, by which at least the machining surface in the surface area to be machined and / or the intensity of the machining beam can be adjusted.

If the processing head comprises a releasably fixed processing optics, one and the same manipulator can be used by exchanging the processing optics for different components and / or differently accessible surface areas. In such case, the processing equipment can be made compact. If the machining head comprises a permanently fixed machining optics, the machining facility can work in a time-optimized manner. This proves to be particularly advantageous if several manipulators are provided with their own processing unit.

Moreover, it proves to be advantageous if the processing unit comprises at least one radiation source in which the processing beam can be generated and fed to at least one conductor means, such as light guide, the processing head and the contact directly on the manipulator, especially in the region of the machining head, or by the manipulator spaced apart.

If the processing unit comprises a radiation source which is located directly on the manipulator, in particular in the region of the processing head, is formed, the processing unit can be made compact. If the radiation source is free of contact with the manipulator, arranging the radiation source is simplified. In addition, this can be designed in such a way that a processing beam of high intensity can be provided.

The suction unit may be designed such that the entire processing system operates with a negative pressure. In this way, the entire processing plant, in particular from top to bottom, be acted upon by an air flow through which at least almost all particles and gases can be sucked, similar to a spray booth with Plänum and tee room.

In addition, it proves to be advantageous if the suction unit comprises at least one suction opening, which is arranged directly or indirectly touching the manufacturing head fixed or fixed.

If the suction unit comprises at least one suction opening which is fixed to the machining head, the gases and suspended particles which are formed during the thermal destruction of the coating can be directly sucked off. In principle, the distance between the machining head and the surface area to be processed can be selected as desired. It has proven to be advantageous if the distance between the machining head and the surface area to be machined is between 200 and 700 mm. In that case, the predominant part of the gases and sulfur particles can easily be absorbed by the suction opening arranged on the machining head.

In one embodiment of the processing system can be provided that the suction unit comprises at least one suction in which a negative pressure can be generated, which is adjustable via at least one suction at the suction, and / or that the suction unit comprises at least one filter means, wherein the suction and filter means is arranged directly on the manipulator, in particular in the region of the machining head, or spaced from the manipulator without contact.

In principle, it is conceivable that the processing system comprises only a single manipulator with a single processing unit arranged on the manipulator. In this case, it is conceivable, if components with complex geometry are machined, that the processing unit comprises a machining head with detachable processing optics. As a result, different areas of the component can be processed by a manipulator and a processing unit.

If the processing system comprises at least two, in particular three, manipulators, the individual processing units do not have to be retrofitted for different areas of the components. In that case, the machining heads of the respective machining units can be fixed inseparably fixed machining optics. This allows a time-optimized processing of the components, since no time-consuming retooling of the processing units is necessary.

1. a. Zuführen und/oder Anordnen einer Komponente in der Bearbeitungsanlage;
2. b. Bearbeiten des Oberflächenbereichs der Komponente durch einen Bearbeitungsstrahl der Bearbeitungseinheit, insbesondere durch thermisches Zerstören zumindest eines Teils der Beschichtung des Oberflächenbereichs;
3. c. Absaugen der insbesondere bei der thermischen Zerstörung der Beschichtung entstehenden Gase und Schwebeteilchen durch die Absaugeinheit.

In addition, the object is achieved by a method for operating a processing plant, in particular with at least one of the aforementioned features, the at least one processing unit, through which at least one surface area of a component can be exposed to a beam generated by a radiation source and emerging from a processing head of the processing unit processing beam and at least a portion of the coating in the surface region is thermally destructible, comprising at least one suction unit, are sucked through, in particular in the thermal destruction of the coating resulting gases and suspended particles, and which comprises at least one manipulator which is multi-axially formed and / or a kinematics comprising several degrees of freedom, and on which at least the machining head of the machining unit can be arranged or arranged, with the steps:

1. a. Feeding and / or arranging a component in the processing plant;
2. b. Processing of the surface area of the component by a processing beam of the processing unit, in particular by thermal destruction of at least part of the coating of the surface area;
3. c. Suction of the resulting in particular during the thermal destruction of the coating gases and suspended particles through the suction unit.

The suction unit may be designed such that the entire processing system operates with a negative pressure. In this way, the entire processing plant, in particular from top to bottom, be acted upon by an air flow through which all particles and gases can be sucked, similar to a spray booth with Plänum and tee room. Furthermore, the suction unit may comprise a suction opening, which can be fixed or fixed directly or indirectly arranged on the machining head.

In a further development of the method, it proves to be advantageous if the machining of the surface area of the component comprises a movement of the manipulator.

Characterized in that the manipulator is movable and is movable relative to the component in the course of editing the surface areas, different areas of the component are improved accessible.

In addition, it proves to be advantageous if the machining of the surface area of the component comprises machining by a first machining unit, which processes a first surface area of the component, and at least one machining by a further machining unit, which processes at least one further surface area of the component ,

Finally, it proves to be advantageous if the suction through the suction unit comprises a suction during and / or after processing by the processing unit.
