Laser Welding Mask Self-Cleaning for Spatter Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser welding devices face issues with foreign materials, such as spatter, accumulating on the welding mask, which degrade welding quality and require frequent mask replacements, leading to production interruptions.
Innovation Solution
A welding device with a foreign material cleaning part featuring a scraper that automatically cleans the welding mask during a standby mode by reciprocating within the seat part of the lower jig, using physical friction to remove accumulated materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the welding mask is replaced periodically to maintain welding quality, then the welding quality is improved, but the production loss increases due to stopping operations
Solution Approach 1:
The welding mask performs self-cleaning through the attached cleaning device that automatically removes foreign materials during or between welding operations, eliminating the need for manual replacement and maintaining welding quality continuously
Solution Approach 2:
The cleaning device removes foreign materials from the welding mask before they can significantly degrade welding quality, performing maintenance in advance during standby periods or between welds to prevent quality deterioration
2Manufacturing precision
If the welding mask is replaced to remove accumulated foreign materials, then the welding quality is improved, but the operation time is reduced due to stopping for replacement
Solution Approach 1:
The cleaning device operates continuously or periodically to remove foreign materials from the welding mask, ensuring welding quality is maintained without interrupting the welding process and eliminating downtime for mask replacement
3Object-generated harmful factors
If manual cleaning or replacement of the welding mask is performed, then foreign materials are removed, but the automation level decreases requiring human intervention
Solution Approach 1:
The welding mask system includes an integrated cleaning device that automatically removes foreign materials without human intervention, performing self-maintenance during welding operations or standby periods
Solution Approach 2:
The manual mechanical process of mask replacement is substituted with an automated cleaning mechanism that uses a cleaning member to remove foreign materials, transitioning from human-operated to automated maintenance
