Product Description

1. Introduction of Prismatic Lithium Battery Pack Assembly Line

A prismatic lithium battery pack assembly line is a production line designed for the manufacturing and assembly of prismatic lithium-ion battery packs. These battery packs are composed of prismatic-shaped lithium-ion cells, which are flat rectangular cells as opposed to the cylindrical or pouch-shaped cells commonly used in batteries.

The assembly line involves various stages of production, including cell inspection, sorting, stacking, and connecting the cells to form the desired battery pack configuration. This process also includes the addition of protective casing, terminals, and the necessary electronics for managing the charging and discharging of the battery.

Overall, the assembly line is a comprehensive manufacturing setup that manages the construction of prismatic lithium battery packs, which are commonly used in various applications such as electric vehicles, portable electronics, and energy storage systems.

1. Action process: The stacking robot grabs materials from the cell conveying line and the end plate feeding table respectively, and performs stacking operations according to the serial parallel order of the module formula. This stacking method can be flexibly compatible with modules with different formula serial parallel orders. combination.

2. The gripper is controlled by a robot, and the gripper is designed with a photoelectric induction cell in place. The module stacking platform adopts a fixed slope double-station design. Each station contains four sets of fixtures, and four batteries can be placed at the same time at a time. When station A is stacking, station B performs the moving work before extrusion synchronously, and the double stations alternately, so as to improve the efficiency of stacking and moving.
