Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coating systems face challenges in efficiently coating vehicles due to interference between coating robots and operation robots, leading to increased installation space and operational costs, and require labor-intensive teaching data creation for symmetrical arm configurations.
Innovation Solution
A coating system with fixed-type operation robots and mobile operation robots, where the fixed-type operation robots are installed on either side of the coating robots, allowing for compact arrangement and shared teaching data, and featuring a six-axis articulated design with adjustable tip jigs to operate vehicle doors and hoods, reducing interference and operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile robots are installed in travel guide rails with different heights, then coating coverage is improved, but installation space and system complexity increase
Solution Approach 1:
The system divides the coating booth into multiple levels by installing travel guide rails at different heights (first and second travel guide rails), allowing mobile robots to operate at different vertical levels. This segmentation enables better coating coverage without requiring excessive horizontal space, as robots can access different areas of the vehicle from elevated positions.
Solution Approach 2:
The patent introduces vertical dimensionality by installing travel guide rails at different heights rather than only horizontal positioning. The first travel guide rail and second travel guide rail are positioned at different vertical levels, allowing mobile robots to move and coat in three-dimensional space, thereby improving coating coverage while controlling installation space requirements.
2Measurement precision
If symmetrical arm configurations are used for operation robots, then operational precision is improved, but teaching data creation becomes labor-intensive
Solution Approach 1:
The patent employs symmetrical arm configurations where the left and right arms are mirror images of each other. This symmetry allows the teaching data created for one arm to be copied and applied to the other arm, significantly reducing the time required for teaching data creation while maintaining operational precision for both arms.
Solution Approach 2:
The symmetrical arm design creates a universal teaching data set that can be applied to both the left and right arms. The teaching data serves multiple functions by being reused for both symmetrical arms, eliminating the need to create separate teaching data for each arm and reducing overall training time.
3Ease of operation
If fixed-type operation robots are installed on both upstream and downstream sides, then interference is reduced, but device complexity increases
Solution Approach 1:
The system segments the operation robot functions by installing fixed-type operation robots at specific locations (upstream and downstream sides) rather than requiring a single complex mobile robot to perform all operations. This segmentation reduces interference between robots by assigning specific operational zones to each fixed-type robot.
Solution Approach 2:
The patent introduces fixed-type operation robots as intermediary devices that handle specific operations (such as door or hood operations) at designated locations. These fixed-type robots act as mediators between the coating robots and the vehicle, reducing interference by dedicating specific spatial zones to specific operational functions.

AI summary
A coating system includes coating robots configured to coat a vehicle, and an operation robot. The operation robot includes a first arm configured to turn around a first axis; a second arm configured to turn around a second axis parallel to the first axis; a third arm configured to turn around a third axis parallel to the first axis; a fourth arm configured to turn around a fourth axis perpendicular to the first axis; a fifth arm configured to turn around a fifth axis parallel to the fourth axis; and a tip jig is supported at the fifth arm and is configured to turn around a sixth axis. The sixth axis is selectively parallel to the fifth axis or perpendicular to a plane which includes the fourth axis and the fifth axis.
