  • Patent number: 10052644
    Abstract: Exemplary coating methods and coating systems, e.g., for coating the component surface of a component with a coating agent by means of an atomizer in a coating system, for example to paint a body part of a motor vehicle with paint, are disclosed. An exemplary method comprises moving the atomizer over the component surface of the component to be coated, or moving the component in the spray jet, thereby applying the coating agent to the component surface by means of the atomizer. The atomizer may be operated with at least one electrical and/or kinematic operating variable comprising a certain voltage for the electrostatic charging of the coating agent and/or a certain rotational speed of a rotating spray element of the atomizer. In one example, the electrical and/or kinematic operating variable of the atomizer may be dynamically varied during the movement of the atomizer.

  • Patent number: 10046361
    Abstract: A component is conveyed in a conveyor direction through a painting installation by conveyor. The component surface of the component to be painted is subdivided into surface painting modules which lie one behind the other in the conveyor direction. The individual painting modules of the component surface are painted one after the other using a multi-axis painting robot that has an atomizer. The painting robot guides the atomizer, within each one painting module, along a painting path and across the component surface of the painting module. The painting path has at least one path section running transverse to the component edge. Within the painting module, the painting path can comprise at least one path section that runs substantially parallel to the component edge.
