Solution Overview
Problem
Secondary batteries can be abnormally loaded in carriers during transfer, leading to damage and electrolyte leakage, which may result in deformation and explosion.
Innovation Solution
A secondary battery transfer apparatus equipped with a loading detection sensor, including a light emitting unit and a light receiving unit, that senses electrode taps to determine if the battery is properly aligned, and a controller to stop the transfer unit if abnormal loading is detected, preventing damage and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic transfer of secondary battery in carrier is implemented, then productivity is improved, but abnormal loading may occur causing damage to battery case and electrolyte leakage
Solution Approach 1:
The patent applies preliminary action by detecting the loading state of the secondary battery in the carrier before the transfer process begins. The detection sensor checks whether the battery is properly loaded, and only if the detection result is normal does the transfer unit proceed with the transfer operation. This prevents abnormal loading from causing damage during automatic transfer, thereby maintaining both high productivity and reliability.
2Reliability
If detection sensor is added to detect abnormal loading, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical detection systems with a simpler sensor-based detection mechanism. The detection sensor used is a standard proximity sensor or photoelectric sensor that detects the presence or position of the secondary battery in the carrier. This substitution maintains high reliability for detecting abnormal loading while significantly reducing device complexity compared to mechanical detection systems.
3Object-affected harmful factors
If transfer unit stops operation upon detection of abnormal loading, then damage prevention is improved, but productivity decreases
Solution Approach 1:
The patent implements feedback control where the detection sensor continuously monitors the loading state of the secondary battery in the carrier. When abnormal loading is detected, the controller receives the detection signal and stops the transfer unit operation to prevent damage. This feedback mechanism ensures damage prevention while minimizing productivity loss by only stopping operation when necessary, rather than continuous stopping.

Function Achieved in This Case
Prevents damage to the secondary battery case and electrolyte leakage by ensuring proper loading, thereby avoiding secondary issues like explosions.
Implementation Method 1
light emitting units emitting light upward via a gap between the diaphragms from the upper surface of the supporter, and a light receiving unit located above the carrier, receiving the light emitted from the light emitting units

AI summary
Disclosed herein are a secondary battery transfer apparatus for transferring a secondary battery in a secondary battery manufacturing process and a method for detecting a loading defect of a secondary battery in a carrier receiving the secondary battery. The secondary battery transfer apparatus includes a carrier having a receipt space to receive a secondary battery, a transfer unit transferring the carrier, a loading detection sensor sensing the secondary battery when the secondary battery inserted into the carrier reaches a designated height, and a controller receiving a result of sensing of the loading detection sensor and controlling operation of the transfer unit. The secondary battery transfer apparatus and the detection method detect whether or not a case of the secondary battery is damaged due to friction with the carrier and thus recognize a product defect in advance.
