Bidirectional Folding Tool Assembly for Pouch Cell Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding processing apparatuses for pouch-type battery cells require increased transfer time and tact time due to the need for separate transfer and folding processes, limiting the efficiency and production rate of sealing portion folding.
Innovation Solution
A folding processing apparatus with a dual-tool assembly that includes a first and second folding processing tool, mounted on a transferable plate, allowing for simultaneous forward and reverse direction transfer to fold sealing portions of battery cells without interference, enabling efficient folding and reduced manufacturing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional folding processing apparatus uses a fixed folding device with separate transfer and folding processes, then the folding processing can be performed on battery cells, but the transfer time and tact time increase, reducing production efficiency
Solution Approach 1:
The patent combines the transfer function and folding function into a single integrated folding tool assembly. The folding tool assembly includes both a first folding processing tool for forward transfer and a second folding processing tool for reverse transfer, allowing the assembly to perform both transfer and folding operations simultaneously during bidirectional movement, thereby eliminating separate transfer and folding processes and reducing overall processing time
Solution Approach 2:
The patent makes the folding tool assembly movable in both forward and reverse directions along the transfer path of the battery cells. By dynamically positioning the folding tool assembly at different locations during bidirectional transfer, the system can perform folding operations on multiple battery cells sequentially without stopping the transfer process, thus reducing tact time and improving production efficiency
2Ease of manufacture
If a fixed folding device is used with battery cells transferred through it, then folding processing can be performed, but the device complexity increases due to separate transfer and folding mechanisms
Solution Approach 1:
The patent merges the transfer mechanism and folding mechanism into a single folding tool assembly that moves bidirectionally. The assembly includes a first folding processing tool for forward transfer and a second folding processing tool for reverse transfer, both integrated on the same movable structure. This integration reduces the number of separate mechanisms needed and simplifies the overall device structure while maintaining folding functionality
Solution Approach 2:
The folding tool assembly serves multiple functions: it transfers battery cells forward and backward along the production line, performs folding operations on sealing portions during both forward and reverse movements, and positions itself at different locations to process multiple battery cells sequentially. This multi-functionality reduces the need for separate dedicated devices for each operation

AI summary
A folding processing apparatus for battery cells includes a folding tool assembly including a first folding processing tool configured to fold a sealing portion of a first battery cell when the folding tool assembly is transferred forward in a first direction, a second folding processing tool disposed offset from the first folding processing tool and configured to fold a sealing portion of a second battery cell when the folding tool assembly is transferred in a reverse direction opposite to the first direction, and a mounting plate on which the first folding processing tool and the second folding processing tool are mounted; and an assembly transferring tool configured to transfer the folding tool assembly.
