Abstract: In a method for controlling a laser body shell welding system, in which a scanning head is attached to a machine arm or is operated as an external tool of the machine arm, the scanning head having at least one scanning mirror for positioning a laser beam on a workpiece to be welded, and the operation of the laser welding system including time-critical functions for controlling the time-critical functions, an embedded control system or a memory-programmable control system is used.

Abstract: During welding with high output power, the gaps between the pieces being joined may not exceed a maximal gap width. A process for laser beam welding is provided, which on the one hand ensures maintaining (not exceeding) a maximal gap width between the sheets and on the other hand makes possible a maximal utilization of the achievable welding speed. The sheets, prior to welding, are first spot welded, wherein they are clamped only during this spot welding in order to ensure the maintenance of a maximum gap width.

Abstract: A vehicle-useful, high-resolution 3D-detection of the environment of a street vehicle with environment scanning sensors is not possible today. Depending on application the first commercially available vehicle integrated systems may be a comprise between resolution of the sensors and size of the sampled area. With the inventive two dimensional distance resolution sensor device it becomes possible, in contrast to those which are known, to produce a system which, installed in a street vehicle, detects and preferably processes complex dynamics scenarios such for example street traffic, from the prospective of the active dynamic moving vehicle. Therein a three dimensional image of the environment is produced using a distance sensor, which produces a two dimensional distance profile (depth profile), and on the other hand, using a data processing and a storage unit, which process and store sequential distance profiles and sequence a series of distance profiles into the three dimensional image of the environment.

Abstract: A method for the mounting of an add-on part (3) on a workpiece (1), in particular on a vehicle body, the intention being for the add-on part (3) to be aligned on the workpiece (1) in a precisely positioned manner in relation to a reference region (12, 13). Use is made of a robot-guided mounting tool (5) which is connected fixedly to a sensor system (20). In order to achieve the precisely positioned alignment of the add-on part (3), an iterative control operation is run through, in the course of which first of all an (actual) measured value of the sensor system (20) is produced and is compared with a (desired) measured value produced within the context of a setting-up phase.

Abstract: The invention relates to a process for the control of the position of workpiece and tool with a robot in a production machine. The objective of the invention is to reduce non-productive secondary processing time during the processing or measuring of a workpiece with a robot. The invention consists of a process for the control of the position of workpiece and tool with a robot in a production machine in which the workpiece (10) is positioned relative to the tool (1), (2) and during a continuous movement of the workpiece (10) with a tool (1), (2) at the processing location of the workpiece (10) a process takes place, and the tool (1), (2) is moving during the process synchronously to and in the same direction like the workpiece (10) and during the continuous movement of the workpiece (10) the tool (1), (2) is moved to and positioned in another processing location.

Abstract: A method for producing a connection area (4) on a work piece (1), in particular on a vehicle body plate which is to be positioned precisely with respect to a reference area (8) on the work piece (1). A robot-guided processing tool (9) is used which is permanently connected to a sensor system (13) and forms a tool/sensor combination (16) with it. In a first step, the tool/sensor combination (16) is moved, within the scope of a positioning phase (II), from a proximity position (24) which is independent of the position of the work piece (1) in the working space (23) of the robot (11), into a preliminary position (18) in which the tool/sensor combination (16) is oriented precisely with respect to the reference area (8) of the work piece (1).

Abstract: The invention concerns a process for pretreatment of a workpiece to be processed with a laser beam, as well as a device for carrying out the process. It is the task of the invention to develop a process and a device, which with small expenditure of material and expense, and with few process steps, makes possible an improved weld seam formation for joining workpieces. The invention is comprised therein, that for the pretreatment of a workpiece to be treated with a laser beam, in which on at least one surface of the workpiece with application of a thermal effect of at least one laser beam emitted by a laser source, rises such as knurls are formed, for the positionally correct and undistorted formation of the rises the time and spatial sequence of a relative movement between workpiece and laser beam and the output over time of the laser source are coordinated to each other via a control computer.

Abstract: A method for processing a moving workpiece (1), in particular a vehicle body (1) which is moved using of a conveyor belt (10). A processing tool (5) is used which is attached to the hand (12) of a robot (7) and comprises a sensor system (18) which is permanently connected to the processing tool (5) and has at least one sensor (19). During the processing, the processing tool (5) follows the moving workpiece. This following movement is based on a closed-loop control process in which the processing tool (5) is oriented periodically towards reference areas (9) of the moving workpiece (1) using measured data of the sensor system (18).

It is the task of the present invention to provide a process for laser beam welding, which on the one hand ensures maintaining (not exceeding) a maximal gap width between the sheets and on the other hand makes possible a maximal utilization of the achievable welding speed. This task is solved in that the sheets, prior to welding, are first spot welded, wherein they are clamped only during this spot welding in order to ensure the maintenance of a maximum gap width.
