Robot Arm Tracking for Automatic Tire Mounting on Moving Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire mounting automation in vehicle production is limited to semi-automated methods, requiring the vehicle body to be stopped for tire mounting, and there are challenges in accurately mounting tires on misaligned or tilted wheel disks.
Innovation Solution
A robot control information providing device with a moving member, coupling interlocking unit, return driving unit, and tracking information providing unit that enables the robot arm to track a moving vehicle body, providing displacement and angle information for precise tire mounting without stopping the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If semi-automated tire mounting method is used, then automation is partially achieved, but vehicle body must be stopped for tire mounting
Solution Approach 1:
The system transitions from static (stopped vehicle) to dynamic (moving vehicle) operation. The robot arm and moving member track the vehicle body's motion in real-time, enabling tire mounting while the vehicle continues to move along the transport line, thus eliminating production time loss.
Solution Approach 2:
The tracking information providing unit continuously provides displacement information about the moving member's position to the robot control unit. This feedback mechanism enables the robot arm to adjust its position dynamically to match the moving vehicle body's location, achieving automated mounting without stopping.
2Extent of automation
If robot arm tracks moving vehicle body, then full automation is achieved, but tracking precision becomes challenging
Solution Approach 1:
The tracking information providing unit continuously provides displacement information about the moving member's position to the robot control unit. This feedback mechanism enables the robot arm to adjust its position dynamically to match the moving vehicle body's location, achieving automated mounting without stopping.
Solution Approach 2:
The system creates a virtual model of the vehicle body's motion through the moving member that couples with the transport carrier. By tracking this copied motion rather than the vehicle directly, the system achieves precise tracking while maintaining automation.
3Adaptability or versatility
If tire mounting is performed on misaligned wheel disk, then mounting flexibility is improved, but mounting precision deteriorates
Solution Approach 1:
The robot arm transitions from static positioning to dynamic adaptive positioning. It continuously adjusts its arm position and angle based on real-time feedback about the wheel disk's alignment status, enabling precise mounting regardless of misalignment or tilt conditions.
Solution Approach 2:
The system changes the robot arm's operational parameters (position, angle, speed) in real-time based on the detected wheel disk alignment. This allows the robot to adapt to misaligned or tilted wheel disks while maintaining mounting precision through continuous parameter adjustment.

AI summary
A robot control information providing device for automatic tire mounting includes a moving member configured to move along the transport direction of a vehicle body, a coupling interlocking unit that couples the moving member with a transport carrier, which transports the vehicle body for tire mounting, thereby allowing the moving member to advance in synchronization with the transport carrier, a return driving unit that provides movement force to the moving member, enabling it to move backward to its original position, and a tracking information providing unit that supplies displacement information of the moving member's forward movement to the control unit of a robot arm for tire mounting.
