Apparatus and method for applying a sealing and/or coating substance

An apparatus for applying a sealing and/or a coating substance to a component, comprising:

• kinematics;
• a spray device;
• and
• a first sensor;
• wherein the apparatus is configured to:
• a) acquire computer-aided design (CAD)-based information on the component;
• and in real time:
• b) acquire actual information on the component by the first sensor;
• c) create a movement profile for the kinematics and an application profile for the spray device on a basis of the CAD-based information and the actual information;
• and
• d) execute the movement profile and the application profile on the component;
• wherein the CAD-based information is categorized in one of a plurality of categories based on measurement information of the component, wherein the plurality of categories each reflects a respective dimensional deviation range from an ideal CAD model of the component, and wherein the dimensions of the component deviate from the ideal dimensions of the ideal CAD model caused by applying a sealing and/or a coating substance to a component.
