The stacking components are evenly distributed along the circumferential direction of the turntable 2. The turntable 2 is a circular plate - like structure and is rotatably connected to the combined table 1. A driving motor for driving the turntable 2 to rotate is arranged on the combined table 1 to make the turntable 2 rotate around its axis. The number of stacking components is two and they are symmetrically arranged about the center of the turntable 2. When the cells in one stacking component are stacked to form a battery module, the turntable 2 rotates 180°, so that the other stacking component is located at the stacking station, and a manipulator 19 is used to clamp away the battery module. The two stacking components work alternately, efficiently connecting with an automatic gluing device, improving the automation degree and processing efficiency of soft - package batteries.

[0022] Such as Figure 2As shown in the figure, the stacking component includes four support angles 3 fixedly arranged on the turntable 2, and the support angles 3 are perpendicular to the turntable 2. The four support angles 3 enclose a rectangular stacking area 16 for accommodating the battery cells. The support angles 3 are arranged vertically. The support angle 3 includes a first folding plate 4 and a second folding plate 5 fixedly connected perpendicular to the first folding plate 4. The connection mode of the first folding plate 4 and the second folding plate 5 is integral connection.
