Method for Coating a Component in a Dipping Bath

Abstract

A method for coating a component in a dipping bath includes ascertaining a volume of gas and triggering an action. The step of ascertaining is carried out with an electronic computing device. In ascertaining step, a volume of gas produced during coating for respective points on a surface of the component is ascertained for an arrangement of the component in the dipping bath. The step of triggering the action is carried out with an electronic computing device. The step of triggering the action depends on the ascertained volume of produced gas at the respective points. The step of triggering the action causes a movement of the produced gas relative to the component.

         11 . A method for coating a component in a dipping bath, comprising:
 ascertaining, with an electronic computing device, for an arrangement of the component in the dipping bath, a volume of gas produced during coating for respective points on a surface of the component; and   triggering an action, with the electronic computing device, depending on the ascertained volume of produced gas at the respective points, thereby causing a movement of the produced gas relative to the component.   
     
     
         12 . The method according to  claim 11 , wherein
 in the ascertaining step, a flow movement of the produced gas starting from the respective points is ascertained and the action is triggered or adapted depending on the ascertained flow movement of the gas.   
     
     
         13 . The method according to  claim 12 , wherein
 the action includes: i) moving the component in the dipping bath and/or ii) subjecting to flow with at least one nozzle of the component in a targeted manner in the dipping bath by a dipping fluid contained in the dipping bath and/or iii) modifying a coating time for the component and/or iv) removing foam collecting on a surface of the dipping bath from the surface, and/or v) modifying a geometry of the component.   
     
     
         14 . The method according to  claim 13 , wherein
 in the modifying of the geometry, at least one venting aperture is provided in the component.   
     
     
         15 . The method according to  claim 14 , wherein
 in the moving of the component, an orientation of the component in the dipping bath is carried out with an electric motor or a mechanically guided slide.   
     
     
         16 . The method according to  claim 15 , wherein
 the orientation is adjusted depending on an ascertained flow movement of the ascertained gas produced at the respective points.   
     
     
         17 . The method according to  claim 16 , wherein
 in the removing of the foam from the surface of the dipping bath, the foam is blown away from the surface with nozzles.   
     
     
         18 . The method according to  claim 17 , wherein
 the component coated is a motor vehicle component.   
     
     
         19 . The method according to  claim 18 , wherein
 the motor vehicle component is a bodywork component.   
     
     
         20 . The method according to  claim 19 , wherein
 the component is coated via electrophoretic deposition.   
     
     
         21 . The method according to  claim 20 , wherein
 a deposition rate for the coating is ascertained for the respective points on the surface of the component and the volume of gas produced during coating is ascertained depending on the deposition rate, and   the deposition rate is ascertained depending on a geometry of the component and/or depending on a voltage applied in the dipping bath and/or depending on an anode position and anode size and/or depending on a process time and/or depending on an electrical resistance of a liquid phase and/or of a solid phase of a dipping fluid contained in the dipping bath, and/or depending on a paint film resistance of a paint film already deposited on the component.
