Electrode Assembly Stacking with Auxiliary Lift Transfer Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for stacking electrode assemblies in secondary batteries often result in damage due to friction and misalignment caused by the receiver (buffer) during the transfer process, leading to torn or misaligned electrodes.
Innovation Solution
An apparatus and method that incorporates an auxiliary lifting mechanism with through holes in the loading plate, allowing the auxiliary lift to elevate electrode assemblies above the receiver, preventing contact and damage during transfer, while maintaining the original lifting member's stroke.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the receiver temporarily loads electrode assemblies during magazine replacement, then continuous production is maintained, but the electrode assemblies are damaged by friction and misalignment
Solution Approach 1:
The patent introduces an auxiliary lift as an intermediary device between the receiver and the electrode assemblies. This auxiliary lift temporarily supports the electrode assemblies during the critical transfer period when the receiver moves outward, preventing direct contact and friction between the receiver and the electrode assemblies, thereby eliminating damage while maintaining continuous production
Solution Approach 2:
The auxiliary lift performs preliminary action by advancing and positioning itself before the receiver moves outward. It proactively prepares to support the electrode assemblies in advance, ensuring they are properly positioned and supported before any potential damage can occur during the transfer process
2Adaptability or versatility
If the receiver moves outward to transfer electrode assemblies, then magazine replacement is enabled, but the electrode assemblies become misaligned and damaged
Solution Approach 1:
The auxiliary lift acts as a mediator that maintains the alignment and position of electrode assemblies during the receiver's outward movement. It provides stable support throughout the transfer process, ensuring that the electrode assemblies remain properly aligned even as the receiver changes position to enable magazine replacement
Solution Approach 2:
The auxiliary lift advances in advance of the receiver's outward movement and positions itself to support the electrode assemblies. This preliminary positioning ensures that when the receiver moves, the electrode assemblies are already supported and aligned, preventing misalignment and damage

AI summary
An apparatus for stacking electrode assemblies includes: a magazine, a loading plate, a lifting member, a receiver, and an auxiliary lifting mechanism. The magazine has a magazine frame defines a storage space within which electrode assemblies can be stacked and stored. The loading plate is configured to support the electrode assemblies and has a through hole. The lifting member is positioned in the magazine frame and is coupled to the loading plate so as to vertically displace the loading plate within the magazine frame. The receiver is positioned above the magazine frame and is movable between a loading position (to temporarily support the electrode assemblies) and a retracted position (to transfer the electrode assemblies to the loading plate). The auxiliary lifting mechanism is coupled to the loading plate and includes an auxiliary lift configured to advance through the through hole of the loading plate.
