Parallel Painting Track for Character Edge Finish
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern painting methods for motor vehicle body components with character edges result in unsatisfactory paint finishes due to paint lines crossing the edges at right angles, leading to paint runs and finish issues under minor changes in paint material properties or climatic conditions.
Innovation Solution
Incorporating a painting method where the painting line within a module has at least one track section running parallel to the component edge, avoiding or minimizing disruptive crossings, with the parallel track section located inside the module and not at turning points, and allowing for dynamic parameter adjustments for optimal painting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the painting line crosses the character edge at right angles, then the painting process is simple and efficient, but the paint finish quality deteriorates due to paint runs and finish issues
Solution Approach 1:
Instead of crossing the character edge perpendicularly as in conventional painting, the patent inverts the approach by having the painting line run parallel to the character edge, fundamentally changing the direction of paint application to eliminate the runs and finish defects caused by perpendicular crossing
2Manufacturing precision
If the painting line runs parallel to the component edge, then the paint finish quality improves by reducing paint runs, but the painting path complexity increases
Solution Approach 1:
The patent applies local quality by making the painting line direction specific to the local geometry of the component - running parallel to character edges where needed for quality, while maintaining perpendicular crossings in other areas, thus optimizing finish quality at critical locations without unnecessarily complicating the entire painting path
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces paint runs and enhances the painting result by ensuring the paint line crosses the character edge less frequently, providing a more consistent and aesthetically pleasing finish.
Implementation Method 1
a stationary painting robot with six movable axes is employed: a rotating robot base, two swiveling robot arms, and a robot hand axis with three movable axes

AI summary
The invention relates to a painting method for painting, in a painting installation, a component (1) that has a component edge (17) and particularly for painting a motor vehicle bodywork component that has a character edge, comprising the following steps: a) conveying the component (1) in a conveyor direction (2) through said painting installation by means of a conveyor; b) segmenting the component surface of the component (1) to be painted into surface painting modules which lie one behind the other in the conveyor direction (2); c) painting the individual painting modules of the component surface one after the other using a multi-axis painting robot that has an atomiser; d) said painting robot guiding the atomiser, within one painting module in each case, along a painting track (5, 11) and across the component surface of the painting module; and e) the painting track (5, 11) having at least one track section (9) running transverse to the component edge (17). It is suggested that, within the painting module, the painting track (5, 11) comprises at least one track section (18, 19) that runs substantially parallel to the component edge (17).
