AI Technical Summary

Technical Problem

Existing automatic battery sleeve packaging machines can only perform sleeve packaging of a single battery, and cannot achieve simultaneous integrated sleeve packaging of multiple batteries. They consume more materials, have higher costs, and have low efficiency due to manual operation.

Method used

An automatic encapsulation machine suitable for multi-cell cylindrical batteries was designed, including feeding, conversion, encapsulation, cutting, baking and discharging mechanisms. The machine achieves integrated encapsulation of multiple batteries through lateral movement, conversion and buffering structures, and a cooling mechanism is set to reduce the temperature of the hopper to ensure battery performance.

Benefits of technology

This technology enables integrated film encapsulation of multiple batteries, improving work efficiency, reducing production costs, ensuring battery reliability and encapsulation quality, and enhancing the smoothness and stability of battery unloading.
