Laser Cutting Jig Structure for Battery Case Spatter Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laser cutting of metal products, such as battery cases, results in spatters that contaminate or defect the product, necessitating additional cleaning processes and potential defects.
Innovation Solution
A laser cutting apparatus with a lower jig, upper jig, laser nozzle, and spatter block jig that supports and fixes the object to be cut, using a spatter block jig to prevent spatters from splashing onto the product by being disposed between the cutting region and the body part, and incorporating a tapered perimeter wall and spatter discharge holes to manage spatters effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If laser beam is used to cut metal products, then cutting precision and ability to process complex shapes is improved, but spatters are generated that contaminate or defect the product
Solution Approach 1:
A spatter block jig is introduced as an intermediary component between the laser cutting zone and the product body. This jig physically intercepts and blocks spatters generated during laser cutting, preventing them from reaching and contaminating the product surface, thereby resolving the contradiction between achieving precise laser cutting and avoiding spatter contamination
Solution Approach 2:
The harmful spatters are extracted or separated from the cutting process by directing them into a spatter collection space defined by the spatter block jig. The jig creates a designated zone where spatters are contained and collected away from the product, effectively removing the contamination threat while maintaining laser cutting precision
2Ease of manufacture
If press die is used to cut metal products, then manufacturing process is simplified, but it is difficult to process complex shapes and thin products are damaged
Solution Approach 1:
The traditional mechanical press die cutting system is replaced with a laser beam cutting system. This substitution enables processing of complex shapes and thin metal products without the limitations of fixed press die geometry, while the added spatter block jig addresses the new spatter contamination issue introduced by laser cutting
3Object-affected harmful factors
If additional cleaning process is added to remove spatters, then product quality is maintained, but manufacturing time and cost increase
Solution Approach 1:
The spatter block jig performs a preliminary protective action during the cutting process itself, blocking spatters before they can contaminate the product. This preventive measure eliminates or reduces the need for subsequent cleaning operations, thereby maintaining product quality while preserving manufacturing efficiency
Solution Approach 2:
The harmful spatters are redirected and contained within the spatter block jig structure, where they serve as indicators of active cutting while being harmlessly collected. The spatter collection space transforms the potentially harmful spatter flow into a controlled containment zone, preventing contamination without requiring additional cleaning steps
