Battery Cell Sorting Jig With Guide Protrusions for Size Defect Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to efficiently sort and identify abnormally sized battery cells, which can lead to manufacturing defects and potential safety issues.
Innovation Solution
An apparatus with a transfer device, sorting jig, guide protrusions, detection sensor, alarm, and remover is used to sort abnormal battery cells by guiding normal-sized cells into an insertion portion and alerting operators to abnormal cells, while automatically removing them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sorting jig with an insertion portion of normal battery cell size is used, then normal battery cells are properly sorted, but abnormal (larger) battery cells cannot be inserted and remain undetected
Solution Approach 1:
A guide portion is introduced as an intermediary component between the transfer device and the sorting jig. This guide portion includes guide protrusions that physically guide abnormal battery cells into the insertion portion, enabling detection without requiring complex sensing systems. The guide portion acts as a mechanical mediator that converts the size difference into a detectable positioning event.
2Productivity
If manual inspection of battery cells is performed, then abnormal cells can be identified, but sorting efficiency and productivity are reduced
Solution Approach 1:
The sorting system performs self-inspection through the interaction between the guide portion and the battery cells. Abnormal cells automatically reveal themselves by failing to be properly guided into the insertion portion, eliminating the need for manual inspection. The system uses the physical dimensions of the cells themselves as the inspection criterion, achieving automated quality control.
3Measurement precision
If a detection sensor and alarm system are added to identify abnormal battery cells, then sorting accuracy improves, but device complexity increases
Solution Approach 1:
The patent replaces complex electronic detection systems with a simple mechanical guidance mechanism. The guide portion with its specific geometry serves as the detection mechanism, using mechanical interaction to reveal abnormal cells. This mechanical substitution achieves detection functionality with minimal additional components, avoiding the complexity of sensors, processors, and control systems.
