1Reliability
If real-time monitoring of activation tray congestion is implemented using position sensors and control units, then the reliability of battery cell protection is improved, but the device complexity increases
Solution Approach 1:
A master tray equipped with position sensors serves as an intermediary device to monitor the positions of multiple activation trays along the transfer line. The master tray collects position data from various trays and transmits this information to the control unit, enabling centralized congestion detection without requiring individual sensors on every tray or complex distributed monitoring infrastructure.
Solution Approach 2:
The monitoring system utilizes the existing master tray in the activation process as a self-service monitoring platform. The master tray, which is already part of the standard activation tray configuration, is equipped with position sensors that automatically detect and report the positions of activation trays along the transfer line, enabling self-monitoring without additional external monitoring equipment.
2Stability of the object's composition
If congestion monitoring and warning systems are added to detect and alert congestion sections, then the manufacturing process stability is improved, but the ease of operation deteriorates due to additional system management
Solution Approach 1:
The control unit continuously receives position data from the master tray's position sensors and automatically compares current tray positions against expected positions. When congestion is detected (trays positioned abnormally close together or stalled), the system generates automatic warnings to alert operators. This closed-loop feedback mechanism maintains process stability by enabling rapid detection and response to congestion conditions without requiring constant manual monitoring.
