Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery production equipment lacks automation, resulting in low efficiency and high labor costs, with idle time during the stacking process due to sequential operation of cutting, clamping, and unwinding mechanisms.
Innovation Solution
An integrated equipment for die-cutting and stacking that includes two electrode die-cutting mechanisms, conveying mechanisms, and a double stacking table mechanism with rotating arms, allowing continuous operation and simultaneous processing of multiple tasks, such as die-cutting, feeding, and stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a Z-type integrated cell stacking machine is used for stacking electrodes with separators, then the stacking process can be completed, but the stacking table must wait for the unloading mechanism to finish cutting, clamping, and withdrawing the separator before continuing stacking, resulting in idle time and low stacking efficiency
Solution Approach 1:
The patent divides the stacking system into multiple independent stacking tables (first stacking table and second stacking table) that can operate simultaneously. While one stacking table is performing stacking operations, another can be performing unloading operations, thereby eliminating idle time and improving overall productivity.
Solution Approach 2:
The patent implements continuous operation by having multiple stacking tables work in parallel. The stacking process continues without interruption as one table completes stacking while another completes unloading, ensuring that the system is always performing useful work rather than waiting for sequential operations to finish.
2Ease of manufacture
If existing single-function equipment is used for die-cutting and stacking operations, then each processing function can be performed, but the equipment occupies large space, has high production cost, and requires high labor consumption
Solution Approach 1:
The patent combines multiple functions (die-cutting, stacking, and unloading) into a single integrated equipment system. By merging these previously separate operations into one unified machine with multiple stacking tables, the patent reduces the number of separate equipment pieces needed, lowers production costs, and decreases space occupation while maintaining all necessary processing capabilities.
Solution Approach 2:
The integrated equipment is designed to perform multiple functions simultaneously - die-cutting electrodes, stacking them with separators, and unloading completed cells. This multi-functional design eliminates the need for separate single-function machines, reducing overall equipment complexity and investment cost while improving manufacturing efficiency.
