Dual Robot Vehicle Coating System Vertical Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coating systems for vehicles struggle to efficiently coat the interior of vehicle bodies due to limitations in robot positioning and interference between opening/closing robots and coating robots.
Innovation Solution
A coating system comprising multiple robots, where a first robot opens an opening/closing portion of a vehicle body, and a second robot, mounted below the first robot, coats the interior through the opened portion. This configuration includes conveyor systems and turning arms to optimize robot positioning and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the opening/closing robot is installed at a position lower than the coating robot, then the robot structure can be simplified, but the operating areas of the two robots interfere with each other
Solution Approach 1:
The patent applies vertical dimensionality by installing the opening/closing robot below the coating robot, utilizing the vertical space within the coating booth. This dimensional arrangement allows both robots to operate simultaneously without horizontal interference, resolving the contradiction between structural simplicity and operational independence.
2Manufacturing precision
If heavy moving devices are installed on the coating booth's ceiling or walls, then the coating robot can be positioned optimally, but the structural load and complexity increase
Solution Approach 1:
The patent extracts the opening/closing function from the coating robot system and implements it as a separate, dedicated robot. This separation allows the coating robot to focus solely on coating operations without carrying additional mechanisms for opening/closing portions, thereby maintaining coating precision while reducing overall system complexity.
Solution Approach 2:
The system is segmented into two independent functional units: a coating robot for applying coating and an opening/closing robot for managing access points. This segmentation allows each robot to be optimized for its specific function, improving coating quality while simplifying the structural requirements of the coating booth.
3Productivity
If a single robot performs both opening/closing and coating functions, then the number of robots is reduced, but the operating efficiency and coating quality decrease
Solution Approach 1:
The patent divides the operational tasks into two separate robots: one dedicated to opening/closing vehicle portions and another dedicated to coating. This functional segmentation enables both operations to proceed simultaneously without interfering with each other, thereby improving overall productivity and coating quality compared to a single multi-functional robot.

AI summary
A coating system includes a first robot configured to open an opening/closing portion of a vehicle body and a second robot configured to coat an interior of the vehicle body through the opening/closing portion opened by the first robot. The first robot has a first base via which the first robot is mounted to a structure forming a coating area. The second robot has a second base via which the second robot is mounted. The second base is mounted below the first base in a vertical direction.
