Solution Overview
Problem
In mass production of pouch-type lithium batteries, applying a uniform and evenly distributed force to each battery during the formation process is a significant challenge, as existing methods fail to consistently maintain the shape and ensure proper chemical structure formation across all units.
Innovation Solution
A tray design featuring a frame, drive shafts, fixed plates, and movable plates that interlace to create receiving spaces for the batteries, allowing for uniform force application through a positioning device and elastic devices to accommodate varying battery thicknesses, ensuring consistent force distribution during the formation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods are used to hold pouch-type batteries, then the structure is simple, but the force distribution is uneven and inconsistent
Solution Approach 1:
The tray is divided into multiple modular components including a frame, multiple drive shafts, fixed plates, and movable plates. Each component performs a specific function in the force application system, allowing for precise control and uniform force distribution across multiple battery pouches simultaneously.
Solution Approach 2:
The tray employs movable plates that can dynamically adjust their position along the drive shafts, enabling the system to adapt to varying battery thicknesses. The elastic devices provide dynamic force adjustment, ensuring consistent force application despite dimensional variations in the battery pouches.
2Stability of the object's composition
If uniform force is applied to all batteries, then chemical structure formation is consistent, but slight thickness variations cause force distribution problems
Solution Approach 1:
The system changes the physical state of the force application mechanism by incorporating elastic devices that can deform and adjust their stiffness. This allows the tray to maintain consistent compressive force on the battery pouches despite variations in initial thickness, ensuring uniform chemical structure formation during the formation process.
Solution Approach 2:
The movable plates can shift position dynamically to accommodate different battery thicknesses, while the elastic devices provide continuous force adjustment. This dynamic adaptation ensures that each battery pouch receives the appropriate force for consistent chemical structure formation regardless of manufacturing tolerances.
3Productivity
If multiple batteries are processed simultaneously, then productivity increases, but force uniformity across all batteries becomes harder to maintain
Solution Approach 1:
The tray is designed with multiple independent but coordinated force application mechanisms, each consisting of a drive shaft, fixed plates, and movable plates. This segmentation allows each battery pouch to receive independent force control while maintaining overall system coordination, ensuring force uniformity across all batteries processed simultaneously.
Solution Approach 2:
The system merges multiple force application mechanisms into a single integrated tray structure that processes multiple batteries simultaneously. The frame connects all drive shafts and plate assemblies, ensuring synchronized operation and uniform force distribution across all battery pouches, thereby maintaining precision while achieving high productivity.

Function Achieved in This Case
The tray effectively applies a uniform and evenly distributed force to each pouch-type battery, enhancing the consistency of the chemical structure formation and reducing variations due to slight differences in battery thickness, thereby improving the manufacturing efficiency and quality of lithium batteries.

AI summary
A tray for placing a plurality of pouch-type batteries is provided. The tray includes a frame, at least a drive shaft, a plurality of fixed plates and a plurality of movable plates. The drive shaft is slidably fixed to the frame along a drive axis, where the drive shaft has a positioning device for fixing a relative position of the drive shaft with respect to the frame. The fixed plates are perpendicular to the drive axis, and are arranged in order along the drive axis and fixed within the frame. The movable plates are also perpendicular to the drive axis, and are arranged in order along the drive axis within the frame, and the movable plates are interlaced with the fixed plates. The movable plates are moved together with the drive shaft, and each of the movable plates and each of the fixed plates define a receiving space for receiving the pouch-type battery, and are used for clamping each of the pouch-type batteries.
