Zigzag Electrode Cutter for Shorter Detached Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrode cutting methods generate thin and long thread-like detached materials during the cutting process, leading to short circuits and bridge phenomena due to the contact between negative and positive electrodes, which are not effectively addressed by existing clearance adjustments or cutter alignments.
Innovation Solution
The electrode cutter employs a zigzag-shaped cutting portion on the upper and/or lower cutters to reduce the length of detached materials, utilizing a zigzag shape with a line segment of 3 mm or less to minimize the generation and length of these materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional straight cutting blades are used, then the cutting process is simple, but thin and long thread-like detached materials are generated causing short circuits
Solution Approach 1:
The cutting blade is designed with a zigzag shape instead of a straight line, creating multiple small cutting segments along the blade edge. This curved/angled geometry reduces the length of detached materials by breaking them into shorter segments, preventing short circuits while maintaining the overall simplicity of the cutter structure
2Manufacturing precision
If the clearance between upper and lower cutters is reduced to minimize detached material, then the cutting precision improves, but the friction force increases causing more detached material
Solution Approach 1:
The zigzag blade geometry creates multiple small cutting angles along the blade edge, allowing for effective cutting with reduced friction compared to a straight blade. The angled segments reduce the normal force between blade and material, decreasing friction-induced detachment while maintaining cut quality

AI summary
Disclosed is an electrode cutter capable of preventing or reducing a thin and long thread-like detached material generated during a process of cutting an electrode or reducing the length of the detached material. The electrode cutter includes an upper cutter and a lower cutter, wherein a zigzag-shaped cutting portion is provided on at least one of a surface of the upper cutter and a surface of the lower cutter in a blade length direction. The zigzag shape prevents the detached material or significantly reduces the length thereof.
