Solution Overview
Problem
Current temperature detection mechanisms for battery cells in production lines suffer from poor universality, as they are designed for single detection items and fail to adapt effectively to varying temperature test requirements across different battery cell types.
Innovation Solution
A detection mechanism comprising a conveying unit, a first detection unit for temperature measurement, and a trigger unit to control the conveying unit based on detection distance, ensuring accurate temperature detection and preventing interference by adjusting the detection distance dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single detection item mechanism is used for temperature detection, then the device structure is simple, but the adaptability to different battery cell types and detection requirements is poor
Solution Approach 1:
The detection mechanism is designed with multiple detection units (first detection unit for side surface temperature, second detection unit for top surface temperature, third detection unit for dielectric voltage withstand test) that can detect different parameters of different battery cell types. The conveying unit can adaptively adjust the detection distance based on the trigger unit's detection, making the mechanism universally applicable to various battery cell configurations and detection requirements.
2Productivity
If the detection distance is not controlled, then the detection process is continuous and simple, but the temperature measurement accuracy decreases and interference occurs when the device is too close to the detection unit
Solution Approach 1:
The trigger unit continuously detects the distance between the conveyed device and the first detection unit, and provides feedback to the conveying unit. When the distance becomes less than a preset value, the conveying unit automatically adjusts to maintain an appropriate detection distance, ensuring both continuous operation and measurement accuracy.
Solution Approach 2:
The detection system transitions from a static fixed-distance detection approach to a dynamic adaptive distance control system. The conveying unit's ability to adjust position based on real-time distance detection allows the system to maintain optimal detection conditions while continuing operation.

AI summary
The present application relates to a detection mechanism and a battery production line. The detection mechanism includes a conveying unit, configured to convey the device to be detected; a first detection unit, configured to detect the temperature of the device to be detected; and a trigger unit, configured to detect the distance between the first detection unit and the device to be detected. When the distance between the first detection unit and the device to be detected is less than a preset distance value, the trigger unit controls the conveying unit to stop conveying. The detection mechanism and the battery production line in the embodiments of the present application can ameliorate the problem of poor universality.
