Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle body assembly systems face inefficiencies and increased costs due to the complexity of handling various vehicle types, requiring frequent jig and robot replacements, which leads to prolonged cycle times and increased initial investment costs.
Innovation Solution
A robot transferring system that includes hangers, vision sensors, and loading robots to accurately detect and position components like cowl plates, roof rails, and package trays without the need for multiple jigs, allowing for flexible assembly across different vehicle types by using vision sensors to determine exact positions and shapes for precise placement on a vehicle body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple jigs and mobile robots are used to handle various vehicle types, then adaptability to different vehicle types is improved, but device complexity and initial investment cost increase
Solution Approach 1:
The patent implements a universal robot system with interchangeable end effectors that can handle multiple vehicle types and component varieties. Instead of having separate mobile robots and jigs for each vehicle type, a single robot platform performs all assembly tasks by swapping tools, achieving multi-functionality that reduces device complexity while maintaining adaptability
Solution Approach 2:
The system employs dynamic reconfiguration through interchangeable end effectors that can be quickly swapped based on the vehicle type and component requirements. This dynamic adaptability allows the same robot to perform different functions without permanent reconfiguration, reducing the need for multiple fixed systems
2Adaptability or versatility
If multiple jigs and mobile robots are replaced based on vehicle type changes, then adaptability is improved, but productivity decreases due to increased waiting time
Solution Approach 1:
The system prepares multiple end effectors in advance for different vehicle types and component types. When a vehicle type change occurs, the pre-prepared appropriate end effector can be quickly swapped without waiting for fabrication or major reconfiguration, maintaining high productivity while responding to various vehicle types
Solution Approach 2:
The dynamic tool swapping capability allows the robot to quickly adapt to different vehicle types by changing end effectors during operation rather than stopping for extensive reconfiguration. This dynamic approach maintains system productivity while providing flexibility for various vehicle types
3Adaptability or versatility
If public devices are prepared for various vehicle types, then adaptability is improved, but initial investment cost increases
Solution Approach 1:
The patent implements a universal robot system with interchangeable end effectors that can handle multiple vehicle types and component varieties. Instead of having separate mobile robots and jigs for each vehicle type, a single robot platform performs all assembly tasks by swapping tools, achieving multi-functionality that reduces device complexity while maintaining adaptability
Solution Approach 2:
The system uses standardized robot platforms that serve as copies for multiple vehicle types. Rather than investing in entirely different robot systems for each vehicle type, the same robot platform is replicated in functionality through end effector swapping, reducing initial investment while maintaining flexibility

AI summary
A robot transferring system of a component and a transferring method thereof are provided. The robot transferring system of a component includes a hanger in which components including at least one of a cowl plate, a roof rail, and a package tray are disposed. A first sensor detects a reference position of the components disposed in the hanger to detect a shape of the component and a first loading robot capture each component based on a predetermined position determined by the sensor. A first loading jig is disposed at a location in which one of the components captured by the loading robot is disposed and a setting robot transfers the components disposed in the loading jig to a vehicle body to dispose the component to a predetermined position of the vehicle body.
