Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser welding devices lack the ability to automatically change between pressing and single direction modes, necessitating manual adjustments and impacting productivity and efficiency when welding vehicle body panels with varying sections.
Innovation Solution
A laser welding device equipped with a shielding gun and a pressing gun, mounted on a robot arm, that can move in multiple directions, allowing for automatic mode switching between pressing and single direction modes based on the welding section requirements, utilizing driving sources and guide rails for precise positioning and beam guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustments are made to switch between pressing and single direction modes, then welding flexibility is maintained, but productivity and cycle time are reduced
Solution Approach 1:
The pressing gun is designed with movable components that can dynamically switch between pressing mode (where the pressing gun contacts the workpiece) and single direction mode (where the pressing gun is retracted). This dynamic configuration allows automatic mode switching based on welding section requirements, eliminating manual adjustments and improving productivity while maintaining welding flexibility.
2Device complexity
If manual disassembly is performed to change welding modes, then device complexity is reduced, but ease of operation and productivity deteriorate
Solution Approach 1:
The device incorporates a movable pressing gun with driving sources that enable automatic mode switching through controlled movement rather than manual disassembly. The pressing gun can be automatically positioned in pressing mode or retracted to single direction mode, improving ease of operation while maintaining manageable device complexity through integrated motion control mechanisms.
3Device complexity
If a fixed gun configuration is used, then device complexity is minimized, but adaptability to various welding sections deteriorates
Solution Approach 1:
The gun configuration incorporates a movable pressing gun that can automatically adjust between pressing mode and single direction mode based on the specific welding section requirements. This dynamic adaptability allows the device to handle various welding sections (such as door openings, cowl side upper portions) without increasing overall device complexity, as the movement is controlled by integrated driving sources and guide rails.
Solution Approach 2:
The pressing gun is designed to perform multiple functions: it can operate in pressing mode for sections requiring gap and step correction, and be retracted to single direction mode for sections not requiring pressing. This multi-functionality allows a single gun configuration to adapt to various welding sections, improving versatility while maintaining relatively simple device structure.
4Adaptability or versatility
If the pressing gun is made movable in multiple directions, then adaptability to various welding sections is improved, but device complexity increases
Solution Approach 1:
The pressing gun is equipped with driving sources and guide rails that enable controlled movement in multiple directions. The guide rails constrain the movement paths, allowing the pressing gun to switch between pressing mode and single direction mode in a systematic manner. This structured approach to multi-directional movement provides the necessary adaptability while keeping device complexity manageable through organized motion control mechanisms.
