Foldable Tape Adsorption for Battery Cell Weld Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery cell packaging devices experience tape meandering and reduced productivity due to manual insulating tape attachment and mechanical defects, leading to weakened adhesive force and increased worker workload.
Innovation Solution
A battery cell packaging device that utilizes a supply part, image acquisition part, adsorption part, and cutting part, with foldable adsorption blocks and image-based control to adjust the adsorption member's position and intimate attachment, preventing tape meandering by aligning edge lines and center lines of the insulating tape and welded portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual insulating tape attachment is performed, then the worker can attach the tape to both sides of the battery cell end, but the adhesive force weakens and tape detachment occurs due to meandering
Solution Approach 1:
The patent replaces the manual mechanical operation with an automated packaging device that uses adsorption members to hold and position insulating tapes. The device mechanically applies tapes to both sides of the battery cell end simultaneously, eliminating meandering and ensuring consistent adhesive force without manual intervention.
Solution Approach 2:
The patent combines the tape attachment operations for both sides of the battery cell into a single automated process. The packaging device applies insulating tapes to the upper and lower surfaces simultaneously through integrated adsorption members, preventing meandering between tapes and ensuring uniform adhesive force across both sides.
2Ease of operation
If manual insulating tape attachment is performed, then the worker can complete the packaging process, but the working hours are longer and productivity is lowered
Solution Approach 1:
The patent replaces manual packaging operations with an automated packaging device that performs tape attachment, cutting, and positioning mechanically. This substitution dramatically reduces the time required for packaging operations and eliminates the need for manual labor in this process, thereby increasing productivity.
Solution Approach 2:
The packaging device is designed to perform the entire insulating tape attachment process autonomously without worker intervention. The device automatically feeds tapes, positions them using adsorption members, applies them to the battery cell, and cuts them to length, making the system self-sufficient and eliminating manual operation time.
3Productivity
If automated battery cell packaging devices are introduced, then productivity increases, but tape meandering occurs due to mechanical defects in the adsorption process
Solution Approach 1:
The patent replaces the problematic mechanical adsorption system with a refined mechanical system that uses specifically designed adsorption members. These members provide more reliable mechanical attachment of tapes, preventing meandering while maintaining high-speed automated operation. The system substitutes the previous inadequate mechanical grip with an improved mechanical engagement mechanism.
