ABSTRACT:
The invention relates to an adhesive robot, comprising a device for applying adhesive to a workpiece. The adhesive robot has a nozzle head (18), which has an application nozzle (24) and can be supplied with a pressurized viscous adhesive, the nozzle head (18) and the workpiece (14) being displaceable in relation to one another. The adhesive which is issued from the application nozzle (24) in a spray jet (28) is applied to a workpiece (14) along a predefined line of application (36) in the form of a strip of adhesive (40). To facilitate the adjustment and re-calibration process, the system comprises at least one camera unit (42), which is located on the nozzle head (18) and whose leans is directed towards the spray jet (28) or the adhesive strip (40). The output of said camera unit is connected to an image evaluation unit (45). The image data (40) recorded by the camera unit (42) is buffered and compared with predetermined image values (40). The decisive control parameters for the system can be calibrated and tracked either automatically or by remote control, on the basis of deviations in the image data that have been determined along the line of application (36).
