Pouch Film Guide Roller Alignment to Prevent Meandering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pouch film supply devices for secondary batteries suffer from guide rollers that are inclined unevenly, leading to meandering of the pouch film, which can cause defects in the processing of pouch type cases and disrupt the manufacturing process, reducing productivity.
Innovation Solution
A pouch film supply device with inclination measurement and adjustment mechanisms for guide rollers, ensuring uniform vertical and horizontal alignment to prevent meandering, and allowing for continuous film supply even during process interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of parts are used to构成 the supply device, then the functional requirements can be met, but the device complexity increases and ease of manufacture deteriorates
Solution Approach 1:
The patent combines multiple functional components into an integrated supply device structure. The housing (110) integrates support functions, the cutting unit (120) and sealing unit (130) are merged into a coordinated system that operates together, reducing the number of separate assemblies needed while maintaining all required functions.
Solution Approach 2:
The supply device is designed with multi-functional components. The housing (110) provides both structural support and positioning functions. The cutting unit (120) and sealing unit (130) work together to perform multiple operations (cutting and sealing) in a integrated manner, allowing a single device to handle various pouch film supply tasks.
2Ease of manufacture
If the structure is simplified to improve ease of manufacture, then manufacturing becomes easier, but the ability to meet functional requirements may deteriorate
Solution Approach 1:
The supply device is divided into distinct modular units: housing (110), cutting unit (120), and sealing unit (130). Each module can be manufactured independently with standardized processes, then assembled together. This segmentation allows each component to be optimized for its specific manufacturing requirements while ensuring the overall system meets all functional specifications.
3Device complexity
If manual operation is used, then device complexity is reduced, but productivity decreases due to repeated replacement operations
Solution Approach 1:
The supply device incorporates an automatic supply mechanism that performs pouch film replacement without manual intervention. The cutting unit (120) automatically cuts the pouch film, the sealing unit (130) automatically seals it, and the supply mechanism automatically feeds the next pouch film into the battery formation apparatus, enabling continuous operation and eliminating repeated manual replacement steps.
