Apparatus and method for manufacturing a rotor blade for a wind turbine, and a wind turbine

A device for manufacturing a rotor blade for a wind energy installation, wherein the rotor blade includes at least two rotor blade shells that are bonded to one another, the device comprising:

• a holding device configured to hold a rotor blade shell in a position in which at least one bonding surface, which is provided on at least one of the rotor blade shell or on a web attached to the rotor blade shell, is exposed, at which bonding surface the rotor blade shell is adapted to be bonded to a further rotor blade shell;
• a guide device mounted on the holding device;
• a robot arm configured to apply adhesive to the at least one bonding surface;
• a carriage movably supported by the guide device and supporting the robot arm thereon;
• wherein the guide device is configured to guide the carriage, together with the robot arm mounted thereon, along the holding device;
• a nozzle provided at the free end of the robot arm and configured to apply adhesive to the bonding surface;
• a valve device configured to control at least one of:
• the amount of adhesive which is applied to the bonding surface by the nozzle, or
• the amount of adhesive which is supplied to the nozzle;
• and
• a control device configured to control the valve device as a function of the type of rotor blade to be manufactured.
