Battery Cell Rack Transfer Layout for Space-Efficient Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery manufacturing systems face inefficiencies in utilizing space where charging and discharging devices are positioned, require separate transport members for different processes, and struggle with removing defective transport members during charging and discharging processes, affecting production efficiency and stability.
Innovation Solution
A battery manufacturing system with a first and second rack, each with charging and discharging rooms, and a transport crane that moves battery cells between these racks, along with transfer loading devices and arrangement processing devices to manage different transport member spacings and enable separate removal of defective members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transport member of different specifications is used in the press pre-charger device, then the charging and discharging process can be performed under pressure, but a separate transfer device is required to move battery cells between different transport members
Solution Approach 1:
The transport member is designed with universal functionality to be used in both general transport processes and the press pre-charger device. The transport member includes a reusable cover that can be attached to maintain pressure during charging and discharging, eliminating the need for separate specialized transport members and transfer devices for the press pre-charger process
2Productivity
If an exclusive conveyor belt is provided for the charging and discharging process, then transport members can be efficiently utilized, but the space occupation and system complexity increase
Solution Approach 1:
The conveyor belt system for the press pre-charger device is merged with the general conveyor belt system. The same conveyor belt transports transport members to both the press pre-charger device and other general processes, eliminating the need for a separate exclusive conveyor belt and reducing space occupation while maintaining efficient transport member utilization
Solution Approach 2:
The conveyor belt is designed with multi-functionality to serve both the press pre-charger device and general transport processes. A single conveyor belt performs multiple functions by transporting transport members to different destinations based on process requirements, reducing the need for duplicate conveyor systems
3Area of stationary object
If transport members are stacked in the charging and discharging device, then space utilization is improved, but defective transport members cannot be removed separately
Solution Approach 1:
The stacked transport members are segmented with individual identification capabilities. Each transport member can be independently identified and controlled even when stacked, allowing defective transport members to be detected and removed separately without disrupting the stacked configuration of other transport members
