Electrode Sheet Cutting with Gripper Air Leak Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode cutting devices fail to ensure uniform cutting of electrodes, leading to misalignment and poor cutting, which increases defects and reduces yield due to air leakage from the gripper cylinder, necessitating manual intervention.
Innovation Solution
An electrode cutting device with a cutting unit, fixing unit, and sensor to monitor the pressure of the gripper, featuring a double-edged cutter and gripper with protrusions or rubber coating for stable fixation, and a pneumatic gauge sensor to detect air pressure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a worker manually checks air leakage from the cylinder through touch, then air leakage can be detected, but dead time increases and yield is reduced
Solution Approach 1:
The patent replaces the manual mechanical detection method (worker's touch) with an automated sensor-based detection system. The sensor automatically monitors the cylinder's air leakage status, eliminating the need for manual intervention and reducing dead time while maintaining detection reliability.
Solution Approach 2:
The system enables self-monitoring of the cylinder's condition through the integrated sensor, allowing the equipment to detect and report air leakage issues autonomously without requiring external human intervention, thus reducing downtime and improving continuous operation capability.
2Reliability
If the gripper pressing force is insufficient due to air leakage, then the electrode sheet cannot be fixed properly, but continuous poor cutting occurs reducing yield
Solution Approach 1:
The sensor provides real-time feedback on the cylinder's air pressure and gripping force status. When air leakage is detected or pressing force becomes insufficient, the system can immediately alert operators or automatically adjust parameters, preventing the occurrence of poor cutting and maintaining high yield.
Solution Approach 2:
The system performs preliminary detection of air leakage and pressing force issues before they cause poor cutting. By monitoring the cylinder status in advance, the system can take preventive measures to maintain proper gripping force and avoid defective cutting operations.
3Manufacturing precision
If manual intervention is required to correct poor cutting, then cutting quality can be improved, but manufacturing efficiency is reduced
Solution Approach 1:
The patent replaces manual intervention with automated sensor monitoring and control systems. The sensor continuously monitors cutting conditions and gripper performance, automatically detecting issues that would otherwise require manual correction, thereby maintaining cutting quality while improving manufacturing efficiency.
Solution Approach 2:
The automated monitoring system enables continuous detection and correction of cutting issues without interrupting the manufacturing process. By maintaining continuous surveillance of the cutting conditions and gripper status, the system ensures consistent cutting quality while minimizing stops and manual interventions.
