Battery Pack Dismantling Layout to Cut Transfer Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lithium-ion battery pack dismantling systems face inefficiencies due to lengthy transfer times and the need for redundant facilities, leading to high construction and management costs.
Innovation Solution
A system with a transfer section using a pair of transfer rails and a gantry robot, a discharge processing section with an index table, a battery disassembly section with worktable and disassembly robots, and a cell extraction section with an extraction robot, all arranged directly below the transfer rails, to streamline the dismantling process and reduce facility redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple robots are arranged in a row with separate worktables and conveyors for each, then each robot can perform dismantling tasks independently, but transfer time increases and redundant facilities are required
Solution Approach 1:
The patent merges multiple separate worktables and conveyors into a single shared worktable and conveyor system. The index table serves as a common transfer point where battery packs are sequentially transferred to different robotic arms for various dismantling operations, eliminating the need for redundant facilities while maintaining independent task execution capability.
Solution Approach 2:
The index table and conveyor system are designed as universal facilities that serve multiple robotic arms simultaneously. The index table can transfer battery packs to different workstations (laser cutting, mechanical disassembly, sealing) and receive them back, making a single facility perform the functions previously requiring multiple separate systems.
2Ease of operation
If multiple separate worktables, conveyors, and lifting devices are provided for each robot, then each robot has dedicated facilities, but system construction cost and management complexity increase
Solution Approach 1:
The patent combines multiple separate facilities into integrated shared facilities. Instead of providing dedicated conveyors and lifting devices for each robot, a single conveyor system with an index table serves all robotic arms, significantly reducing the number of components and simplifying system management while maintaining operational efficiency.
Solution Approach 2:
The index table is designed as a multi-functional universal facility that performs transfer, positioning, and coordination functions for multiple robotic arms. This single universal facility replaces what would otherwise require multiple specialized facilities, reducing construction cost and management complexity.
3Ease of operation
If redundant facilities are provided for each robot including worktables, conveyors, and lifting devices, then each robot can operate independently, but task efficiency decreases due to increased transfer time
Solution Approach 1:
The patent merges redundant facilities into a streamlined shared system where the index table and conveyor enable rapid sequential transfer between workstations. This eliminates the time-consuming transfers required by separate facilities while maintaining independent operation capability through coordinated robotic arm control.
Solution Approach 2:
The index table enables continuous transfer of battery packs between different dismantling stations without interruption. While one robotic arm is working on a battery pack at a particular station, the index table can simultaneously transfer the next battery pack to another station, ensuring continuous productive action across the entire system.

AI summary
The system for dismantling the spent lithium-ion battery pack includes: a transfer section including transfer rails and a gantry robot on the transfer rails; a discharge processing section including an index table on which a discharging task of discharging a battery pack is performed; a battery disassembly section including a worktable on which a disassembly task is performed to cut connections of the battery pack, disassembly robots, and first transfer trolleys; and a cell extraction section including an extraction robot, a second transfer trolley configured to carry out battery cells, of which the connections have been cut by the disassembly task, to the outside, and a third transfer trolley configured to carry out a tray on which the battery cells are placed to the outside. The index table, the worktable, the second transfer trolley, and the third transfer trolley are arranged directly below the transfer rail.
