Electrode Sheet Cutting With Integrated Full-Width and Edge Beveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrode manufacturing process is inefficient due to separate full-width and edge cutting processes, which prolongs work time and often results in non-uniform cutting of electrode edges, leading to defects.
Innovation Solution
An electrode cutting device that integrates full-width and edge cutting processes by using a die member with full-width and V-shaped cutting grooves, along with a punch member comprising full-width and V-shaped punches, to simultaneously cut the electrode sheet, forming inclined edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If full-width cutting process and edge cutting process are performed separately, then each cutting can be done with dedicated tooling, but it takes a lot of work time and reduces productivity
Solution Approach 1:
The patent combines the full-width cutting process and edge cutting process into a single integrated operation. The die member includes both full-width cutting grooves and V-shaped cutting grooves for edge cutting, while the punch member includes corresponding full-width punches and V-shaped punches. This allows both cutting operations to be performed simultaneously in one stroke, eliminating the need for separate processing steps and significantly improving productivity while maintaining cutting precision through dedicated tooling geometry.
2Ease of manufacture
If separate cutting processes are used, then cutting can be performed, but the edge of the electrode is not cut uniformly and defects occur
Solution Approach 1:
The integrated die member combines full-width cutting grooves and V-shaped cutting grooves for edge cutting, with corresponding punches that perform both operations simultaneously. This ensures uniform edge cutting through the specialized V-shaped geometry while maintaining process simplicity by eliminating separate operation steps and reducing the number of process parameters that need to be controlled.
3Manufacturing precision
If multiple separate cutting processes are implemented, then comprehensive cutting coverage is achieved, but device complexity increases
Solution Approach 1:
The patent integrates multiple cutting functions into a single die member and punch member assembly. The die member includes full-width cutting grooves and V-shaped cutting grooves for edge cutting, while the punch member includes corresponding full-width punches and V-shaped punches. This consolidated design achieves comprehensive cutting coverage (full-width and edge cutting) while reducing device complexity by eliminating the need for multiple separate cutting devices and process steps.
