Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding jigs used in laser welding processes suffer from reduced quality due to foreign matter like spatter adhering to them, which is not effectively addressed by current cleaning technologies.
Innovation Solution
A micro-blaster system integrated with a welding jig cleaning apparatus, featuring a housing, sandbox, air supply unit, blasting gun with a jig fixing portion, and controller, allows for horizontal movement and upward-downward rotation of the jig fixing portion to remove pollutants like spatter efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ultrasonic welding is used to connect electrode tab and electrode lead, then welding is performed, but foreign matter like spatter is generated and attached to welding jig, lowering welding quality
Solution Approach 1:
The micro-blaster cleaning apparatus performs preliminary cleaning of the welding jig before welding operations to prevent spatter accumulation. The system proactively removes foreign matter before it degrades welding quality, rather than reacting after contamination occurs.
Solution Approach 2:
The micro-blaster acts as an intermediary cleaning device between the welding process and the welding jig. It introduces abrasive particles through a nozzle to mediate the removal of spatter, protecting the welding quality without interfering with the welding operation itself.
2Ease of operation
If conventional cleaning methods are used on welding jig, then cleaning is performed, but cleaning efficiency is insufficient and welding quality is not improved
Solution Approach 1:
The system replaces conventional mechanical cleaning methods with a micro-blaster apparatus that uses pressurized abrasive particles. This substitution enables more effective removal of spatter through fluid dynamics and particle impact rather than traditional mechanical contact.
Solution Approach 2:
The micro-blaster changes the cleaning parameters by introducing pressurized gas flow and abrasive particles with specific velocity and distribution characteristics. These parameter changes enable thorough cleaning of difficult-to-reach areas on the welding jig that conventional methods cannot access.
3Productivity
If welding jig is not cleaned, then welding operations continue, but spatter accumulates on welding jig, reducing welding quality
Solution Approach 1:
The micro-blaster cleaning system enables continuous cleaning action during or between welding operations. By maintaining constant readiness to clean and performing frequent brief cleaning cycles, the system ensures uninterrupted welding productivity while continuously removing spatter to maintain quality.
