Battery Film Coating Gap Detection Before Hot Melting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of traction batteries is compromised due to inconsistencies in the coating of the film on the battery cell, leading to potential dislocation and damage during the hot melting process.
Innovation Solution
A detection method and system that captures images of the battery cell coated with a film and the end cover, measures the gap between the film edge and the end cover, and adjusts the coating position if necessary to ensure the gap meets a preset standard before hot melting treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the film coating process is performed manually or without precise control, then the coating can be applied to the battery cell, but the coating quality becomes inconsistent leading to dislocation and damage during hot melting
Solution Approach 1:
The patent performs detection of the film edge position relative to the end cover before the hot melting process. By detecting the gap value in advance and determining whether it meets preset standards, the system identifies coating issues before they cause damage during hot melting, preventing quality deterioration and enabling corrective actions to be taken proactively
Solution Approach 2:
The patent implements a feedback mechanism where the detected gap value is compared against preset standards, and the detection result is used to determine whether the coating quality meets requirements. This feedback loop enables continuous monitoring and quality control throughout the production process, allowing for real-time adjustments to maintain consistent coating quality
2Measurement precision
If automated detection is implemented to monitor film coating quality, then the accuracy and efficiency of quality control improves, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical detection systems with an image processing-based detection method. By capturing images of the battery cell with film coating and using image analysis to determine the gap value between the film edge and end cover, the system achieves high measurement precision while avoiding the complexity of specialized mechanical measurement devices
Solution Approach 2:
The patent uses image copying to create a digital representation of the physical coating state. By capturing an image of the film-coated battery cell and analyzing the image data to determine gap values, the system transforms physical measurement into digital processing, simplifying the detection apparatus while maintaining high measurement accuracy
