Electrolyte Leak Detection Plate for Battery Transfer Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Secondary batteries can be contaminated during the electrolyte injection process, leading to defects and secondary contamination, as the electrolyte may leak and stain on the surface, contaminating handling equipment like jigs or grippers.
Innovation Solution
An electrolyte detection device with a contamination detection plate, first and second conductors spaced apart to prevent initial current flow, and a power member connected to these conductors to detect electrolyte leaks, which triggers a contamination detection signal, integrated into a secondary battery transfer facility to prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a jig or gripper is used to transfer the secondary battery after electrolyte injection, then the battery can be moved to the charging/discharging process, but the electrolyte may leak and contaminate the battery surface and the handling equipment, causing secondary contamination
Solution Approach 1:
The contamination detection plate is positioned to contact the battery surface before the battery is transferred by the gripper, performing preliminary detection of electrolyte leakage. This allows contamination to be detected early, preventing secondary contamination during subsequent handling operations.
Solution Approach 2:
The contamination detection plate acts as an intermediary between the battery and the gripper, providing a detection interface that identifies electrolyte contamination without requiring direct contact between the gripper and the potentially contaminated battery surface.
2Measurement precision
If the contamination detection plate contacts the battery surface to detect electrolyte leaks, then contamination can be detected, but the detection device must be precisely positioned to ensure accurate detection across different battery sizes
Solution Approach 1:
The contamination detection plate is designed with adjustable positioning capabilities, allowing it to dynamically adapt its position relative to the battery surface. This enables precise contact with the battery at different locations depending on the specific battery dimensions and contamination patterns.
Solution Approach 2:
The detection device allows for adjustment of geometric parameters such as the position and orientation of the contamination detection plate. By changing these parameters, the device can be optimized for different battery sizes and shapes, maintaining detection accuracy without requiring a completely different device for each battery type.
