Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrode cutting processes suffer from interference between edge lanes and slitting lanes, leading to disconnection of cutting residues and damage to the cut surface of electrodes due to inadequate meandering adjustment.
Innovation Solution
A discharge device and electrode slitting system featuring a meandering adjustment roller with comb patterns on its surface, which adjusts the position of cutting residues in one or the other direction to prevent interference and maintain tension, combined with a suction unit for discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If meandering adjustment or tension adjustment is not performed during the discharge process of edge lanes, then the discharge device complexity is reduced, but interference occurs between edge lanes and slitting lanes causing disconnection of cutting residues
Solution Approach 1:
A meandering adjustment roller is introduced as an intermediary device between the edge lanes and the discharge part. This roller actively adjusts the meandering of cutting residues during discharge, preventing interference with slitting lanes while maintaining simple overall device structure. The roller serves as a mediator that resolves the contradiction by providing targeted adjustment only where needed.
2Object-affected harmful factors
If the separated distance between edge lane and slitting lane is increased, then interference between lanes is reduced, but the cut surface of slitting lane becomes damaged due to excessive separation
Solution Approach 1:
The meandering adjustment roller provides dynamic adjustment of the cutting residue position during the discharge process. Instead of maintaining a fixed separation distance, the system dynamically adapts the position of edge lanes to prevent both interference and excessive separation, thereby protecting cut surface quality while reducing lane interference.
3Reliability
If meandering adjustment is performed during the discharge process, then disconnection of cutting residues is prevented, but the device complexity and adjustment requirements increase
Solution Approach 1:
The meandering adjustment roller serves as a dedicated intermediary component that handles the meandering adjustment function. By isolating this adjustment function to a specific roller, the overall device complexity is minimized while still achieving reliable prevention of cutting residue disconnection.
4Manufacturing precision
If meandering adjustment is performed during the discharge process, then damage to the cut surface of electrodes is minimized, but the device complexity increases
Solution Approach 1:
The meandering adjustment roller acts as a specialized intermediary device that protects cut surface quality by preventing excessive separation between lanes. This targeted approach maintains high manufacturing precision while adding minimal complexity to the discharge system.
