Coil Transfer Support Arm for Precise Automated Core Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for handling coils and cores in battery cell production lack full automation, particularly in precision transfer and handling, making it difficult to achieve high automation and reproducibility in production chains.
Innovation Solution
A stationary device with a support arm and stand, allowing for rotational and linear movement, is used to transfer coils or cores between a support arm and a receiving mandrel, enabling precise and repeatable handling without the need for complex sensor systems or programmable AGVs, utilizing a fixed travel path for the stand and displacement units for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated guided vehicles (AGVs) are used for coil or core handling, then automation is improved, but precision transfer and reliability deteriorate due to high precision requirements during transfer
Solution Approach 1:
A stationary receiving unit with support arm acts as an intermediary between the winding station and coil storage/transport. This receiving unit with its support arm and displacement unit provides a stable, precise interface for transferring coils and cores, eliminating the need for complex AGV systems while maintaining high automation through the stationary device's controlled movements
Solution Approach 2:
The patent replaces the complex mechanical AGV system with a stationary device featuring a support arm and displacement unit. This substitution eliminates sensors and programming complexity while achieving precise transfer through mechanical control of the support arm's movement along a fixed path between the winding station and storage locations
2Extent of automation
If complex sensor systems and programmable AGVs are used, then automation is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex sensor systems and programmable AGVs with a stationary device that uses a support arm and displacement unit. This mechanical system achieves automation through simple, controlled movement along a fixed path, eliminating the need for sensors, programming, and complex control systems
Solution Approach 2:
The stationary receiving unit with its support arm and displacement unit performs all handling operations autonomously through mechanical movement. The system serves itself by using the support arm to pick up coils and cores directly from the winding station and transfer them to storage or transport positions without external sensor guidance or programming
3Extent of automation
If AGVs are used for coil handling, then automation is improved, but ease of operation deteriorates due to difficulty in practical use
Solution Approach 1:
The stationary receiving unit with support arm serves as an intermediary that simplifies operation. Instead of using complex AGVs that are difficult to operate in practice, this stationary device provides a simple, reliable interface for coil and core handling that is easy to operate and maintain while achieving high automation
Solution Approach 2:
The patent replaces difficult-to-operate AGVs with a stationary device featuring a support arm and displacement unit. This mechanical system is much easier to operate in practice because it eliminates the complexity of AGV navigation, sensing, and programming, providing simple, direct mechanical transfer of coils and cores
