Battery End Cover Mounting with Rubber Strip Tab Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During battery production, the limited space inside batteries often results in bent tabs coming into contact with the aluminum shell, causing short circuits and damage due to insufficient space for the bent tab.
Innovation Solution
A battery end cover mounting device and method that includes a manipulator for assembling the end cover and a rubberizing mechanism to apply a rubber strip between the end cover and the battery, preventing contact between the tab and the shell, comprising a manipulator with clamping components and a rubberizing module with suction blocks and a telescopic ejector block to securely mount the end cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the battery space is reduced to increase energy density, then the energy density is improved, but the bent tab contacts with the aluminum shell causing short circuit
Solution Approach 1:
An end cover is introduced as an intermediary component between the bent tab and the aluminum shell. The end cover accommodates the bent tab and prevents direct contact with the shell, eliminating the short circuit hazard while maintaining compact battery design for high energy density.
Solution Approach 2:
The battery internal space is segmented by introducing the end cover as a separate component. This segmentation isolates the bent tab within the end cover structure, preventing it from contacting the aluminum shell while maintaining overall compactness for high energy density.
2Productivity
If the end cover mounting process is simplified to increase productivity, then the productivity is improved, but the assembly precision and reliability may deteriorate
Solution Approach 1:
The manual or complex mechanical mounting process is replaced with an automated manipulator system. The manipulator with specialized clamping components automatically positions and secures the end cover, high-speed rubberizing mechanism applies adhesive strips, ensuring consistent precision while increasing assembly speed and productivity.
Solution Approach 2:
The end cover and tab assembly structure is designed to be self-aligning and self-securing. The tab naturally fits into the end cover opening, and the rubberizing mechanism automatically applies adhesive strips to secure the connection, enabling fast automated assembly without complex positioning mechanisms while maintaining high precision.
