The invention has for its object to provide a functionally improved and effective marking device for marking a vehicle component. This object is achieved by a marking device with the features of claim 1, by a processing arrangement with the marking device and by a method for processing a vehicle component with the processing arrangement. Preferred or advantageous embodiments of the invention result from the subclaims of the following description and / or the attached figures.

A marking device is proposed which is designed to introduce a marking into a vehicle component, which is / is preferably conveyed continuously on a conveying device. The vehicle component is preferably a component of a vehicle, in particular a car, for example a section of a vehicle structure and / or a vehicle body. The marking can be designed, for example, as a vehicle identification number or as another character string.

The conveyor is, for example, a conveyor belt that the vehicle component can continuously, in particular without stopping, convey through a production line. In particular, the marking is introduced during and / or during a e.g. continuous conveyance of the vehicle component through the production line.

The marking device comprises a movable handling device and a processing attachment for arrangement on the vehicle component, in particular for placement on the vehicle component. For example, the handling device is designed as a robot arm, manipulator or as a rail-guided positioning system. It is possible within the scope of the invention that the handling device can be moved and / or moved, in particular along the conveying device. The handling device can preferably be moved and / or moved synchronously with the conveying device.

The handling device carries the processing attachment. The processing attachment is preferably arranged on or on the handling device. In particular, the processing attachment is kinematically connected to the handling device. The processing attachment can thus be moved by means of the handling device and can be arranged in a marking position on the vehicle component. In particular, the processing attachment can be placed on the vehicle component in the marking position. The vehicle component can preferably be marked in the marking position by the processing attachment. The marking can in particular be introduced mechanically into the vehicle component. For example, the marking can be introduced into the vehicle component using a laser beam.
In a possible constructive embodiment of the invention, the processing attachment for marking the vehicle component comprises a laser device which is designed to emit the laser beam onto the vehicle component. In particular, the laser device emits the laser beam when the processing attachment is arranged in the marking position.

In a possible implementation of the invention, the marking device comprises at least one fastening device for the processing attachment. The processing attachment can preferably be attached and / or attached to the vehicle component by means of the at least one fastening device if the processing attachment is arranged in the marking position. The at least one fastening device is, for example, at least one clamping device, at least one vacuum device or at least one electromagnetic device Facility. In particular, the processing attachment can be fastened and / or fastened in the marking position on the vehicle component by means of at least one clamp of the clamping device, by means of at least one suction cup of the vacuum device or by means of at least one electromagnet of the electromagnetic device. Optionally, in addition, the marking device comprises a positioning aid that supports the positioning and / or fastening of the processing attachment in the marking position. It is advantageous that the processing attachment is securely arranged in the marking position by the at least one fastening device during and / or during processing and the marking can be introduced at the correct point.

The marking arrangement has a decoupling device which is designed for the kinematic decoupling of the machining attachment from the handling device. The processing attachment can preferably be decoupled and / or decoupled from the handling device in the marking position by the decoupling device. In particular, the processing attachment assumes a decoupled state in the marking position.

It is advantageous that the processing attachment in the decoupled state can be synchronized with movements and / or vibrations of the vehicle component conveyed, for example, on the conveyor. In particular, the processing attachment can be tuned in the decoupled state to disturbing movements which the vehicle component executes relative to the handling device. This can ensure that the marking can be introduced by means of the laser beam safely and with high quality even if the vehicle component makes unwanted disturbing movements to the handling device due to environmental conditions. In particular, this can reduce costs for reworking the vehicle component or for rejects due to a qualitatively inadequate marking.

It is possible within the scope of the invention that the vehicle component is exposed to the disturbing movements on the conveyor device which are directed relative to the handling device. In particular, the vehicle component itself carries out the disturbing movements relative to the handling device.

The sensor device preferably detects position data of the handling device and / or of the machining attachment and of the vehicle component. For this purpose, the sensor device comprises, for example, at least one path or distance sensor. In particular, an evaluation device integrated in the control device compares the position data of the handling device and / or the machining attachment and the vehicle component, so that the handling device can be controlled to position the machining attachment securely in the marking position even during and / or during the continuous conveyance of the vehicle component .

It is further preferred that the control device controls the handling device, the fastening device and / or the decoupling device as a function of the position data. In particular, the control device controls the handling device as a function of the position data for moving the processing attachment into the marking position. Optionally, in addition or alternatively, the control device controls the fastening device as a function of the position data for fastening the processing attachment in the marking position. It is also possible within the scope of the invention that the control device controls the decoupling device in dependence on the position data for the kinematic decoupling of the processing attachment from the handling device in the marking position. Optionally, in addition, the control device controls the kinematic coupling of the processing attachment with the handling device, in particular after a defined period of time has passed and / or when the processing of the vehicle component has been completed and the marking has been introduced. In particular, the control device controls the handling device for transferring or returning the processing attachment in a rest position, in which the processing attachment is provided for processing another vehicle part.

In the context of the method, it is preferred that the processing attachment is moved into the marking position and is fastened to the vehicle component in the marking position. As part of the method, the machining attachment is kinematically decoupled from the handling device in the marking position. The marking is preferably introduced into the vehicle component at the same time as the kinematic decoupling, overlapping with the kinematic decoupling or after the kinematic decoupling. In particular, the processing attachment, in the decoupled state, executes the interference movements relative to the handling device together with the vehicle component. In particular, the machining attachment is kinematically coupled to the handling device after the machining of the vehicle component and / or after the marking has been completed. Optionally, in addition, the processing attachment is moved away from the vehicle component and transferred to the rest position, in which it is made available for processing the further vehicle part.
