Solution Overview
Problem
Existing robotic spot welding systems face issues with electrode maintenance, as the pressure applied during electrode change can damage equipment and ground connections, leading to costly repairs and increased space requirements due to separate control and correction processes.
Innovation Solution
A multi-purpose station with a spring connection system that absorbs pressure during electrode change, integrating trimming, changing, and tool check point features into a compact system, using a base plate, profile, electrode removal and changing systems, and a spring connection system to prevent damage and optimize space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the robot applies pressure on the charger to take the new electrode, then the electrode can be compressed into the adapter, but the pressure is transferred to the whole system and ground connection causing breaks and ruptures
Solution Approach 1:
A spring mechanism is introduced as an intermediary between the robot and the charger. The spring absorbs the pressure applied by the robot during electrode installation, preventing force transmission to the ground connection while still enabling electrode compression into the adapter.
Solution Approach 2:
The spring mechanism is pre-installed on the charger to provide cushioning before the robot applies pressure. This beforehand cushioning protects the ground connection from ruptures by absorbing the impact force during electrode installation.
2Measurement precision
If the robot reference point is mounted in a separate location for control and correction process, then leakage at robot end point can be corrected, but extra space is required in the automatic area
Solution Approach 1:
The reference point function is merged with the gun tip changing station. The station serves dual purposes: electrode maintenance and robot reference point, eliminating the need for a separate reference point location and reducing space requirements.
Solution Approach 2:
The gun tip changing station is designed with multi-functionality, serving both as an electrode maintenance station and as the robot reference point. This universal design allows the same structure to fulfill multiple functions without requiring additional space.
