Battery Tab Imaging with Dual-Axis Positioning and Prism Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tab image acquisition devices for battery cells are limited in their application scope due to the inability of their mobile modules to move in multiple directions, restricting the adjustment of the image acquisition module's location and the prism module's position based on varying tab displacements and spacings, which affects the clarity and range of tab image acquisition.
Innovation Solution
The introduction of a dual mobile module system, where the first mobile module moves in one direction and the second mobile module, installed on the first, moves in a perpendicular direction, allowing the image acquisition module to adjust its position in two directions, and the prism module, with a reflective surface, adjusts its angle to ensure incident light enters the module effectively, while a telescopic unit prevents collisions with the battery cell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single mobile module is used to move the image acquisition module in one direction, then the device structure is simple, but the application scope is limited when tabs are displaced or have varying spacings
Solution Approach 1:
The patent introduces a second mobile module that moves the image acquisition module in a second direction B that intersects with the first direction A. This two-dimensional movement capability allows the image acquisition module to track tabs with displacements in multiple directions and accommodate varying tab spacings, significantly broadening the application scope without creating an overly complex device structure
Solution Approach 2:
The patent employs two mobile modules with independent driving units that can dynamically adjust the position of the image acquisition module based on the actual displacement and spacing of tabs. This dynamic adjustment capability enables the device to adapt to different battery cell configurations and tab positions, resolving the contradiction between simplicity and versatility
2Measurement precision
If the image acquisition module position is fixed, then the device structure is simple, but clear tab images cannot be obtained when tabs are displaced
Solution Approach 1:
The patent uses mobile modules with driving units that can dynamically position the image acquisition module to track displaced tabs. The first mobile module moves the module in the first direction A, and the second mobile module moves it in the second direction B, ensuring the image acquisition module remains aligned with the tab position to maintain image clarity
Solution Approach 2:
The patent incorporates a displacement detection apparatus that detects the displacement amplitude of tabs and provides feedback to control the movement of the mobile modules. This feedback mechanism ensures the image acquisition module automatically adjusts its position to maintain optimal imaging conditions, achieving high measurement precision while managing device complexity through automated control
3Reliability
If the prism module position is fixed, then the device structure is simple, but incident light cannot effectively enter the image acquisition module when tabs are displaced
Solution Approach 1:
The patent makes the prism module movable by installing it on the first mobile module, allowing it to move in the first direction A. The reflective surface of the prism module can change the angle of incident light on the tab, ensuring that reflected light effectively enters the image acquisition module even when tabs are displaced, thereby maintaining reliable light entry effectiveness
Solution Approach 2:
The patent introduces a telescopic unit that moves the prism module in a third direction C that intersects both the first direction A and the second direction B. This additional degree of freedom allows the prism module to adjust its position in three-dimensional space, ensuring optimal light reflection angles are maintained regardless of tab displacement, enhancing reliability while managing structural complexity
