Dual-Outlet Plasma Cleaning for Sealing Block Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sealing tool for secondary batteries faces issues with foreign substances, particularly organic materials, accumulating on the pressing surfaces of sealing blocks, leading to weakened sealing force, quality defects, and potential damage to the pressing surfaces.
Innovation Solution
The cleaning equipment employs a plasma generation device and a torch device with dual plasma outlets to automatically remove foreign substances from the pressing surfaces of both sealing blocks, utilizing plasma to chemically react with and break down organic materials into carbon dioxide and water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning methods are used for sealing tools, then operational simplicity is maintained, but cleaning effectiveness deteriorates due to inaccessible crevices and high contamination risk
Solution Approach 1:
The cleaning apparatus uses a nested structure where the cleaning element is positioned within the sealing tool body, allowing the cleaning element to access crevices and contours that would be inaccessible with external manual cleaning methods. The cleaning element is nested such that it can be inserted into and cleaned within the sealing tool's own structural features.
Solution Approach 2:
The sealing tool is designed to clean itself through the integrated cleaning element that automatically contacts and cleans the sealing surface during operation. This self-cleaning mechanism eliminates the need for external manual cleaning operations, improving cleaning effectiveness while maintaining operational simplicity.
2Reliability
If sealing tools operate in harsh environments, then functional performance is maintained, but contamination from foreign substances increases
Solution Approach 1:
The cleaning element is positioned to proactively remove foreign substances and contaminants from the sealing surface before they can cause damage or compromise sealing performance. This preliminary cleaning action prevents contamination rather than merely responding to it after occurrence.
Solution Approach 2:
The cleaning element operates continuously during sealing tool operation, maintaining constant contact with the sealing surface to continuously remove contaminants. This continuous cleaning action ensures that the sealing surface remains free of harmful substances throughout operation in harsh environments.
3Reliability
If sealing tools have complex geometries with crevices, then sealing capability is improved, but accessibility for cleaning deteriorates
Solution Approach 1:
The cleaning element is nested within the sealing tool structure, allowing it to penetrate into crevices and complex geometries. This nested configuration enables the cleaning element to reach areas that would be inaccessible to external cleaning methods, maintaining ease of cleaning despite complex sealing geometries.
Solution Approach 2:
The cleaning element is specifically designed with localized cleaning features that match the complex geometries of the sealing tool. Different portions of the cleaning element are configured to address specific crevices and contours, providing targeted cleaning capability where needed while maintaining overall simplicity.
