[0032] Embodiment 1:

[0033] This embodiment provides a cell stacking and grouping device, including:

[0034] A cell stacking and grouping device, including:

[0035] A workbench 1, on which a support slide rail 2 is provided, and the support slide rail 2 is used to place the cell group to be stacked;

[0036] A pressing mechanism, which is located at one end of the support slide rail 2 and is used to press the cell group to be stacked;

[0037] A fixed stop block 3, which is movably installed on the other end of the support slide rail 2;

[0038] A positioning and fixing assembly, which includes a positioning member and a reset member 4. The positioning member is axially movably installed in the fixed stop block 3, and the reset member 4 is installed in the fixed stop block 3 and is used for resetting the positioning member;

[0039] Wherein, a plurality of positioning holes 5 are provided on the support slide rail 2 at intervals along the length direction of the support slide rail 2. In the reset state of the reset member 4, the end of the positioning member is adaptively engaged with the positioning hole 5.

[0040] Furthermore, the fixed stop block 3 includes an installation hole 6 for installing the positioning member;

[0041] The positioning member includes a positioning block 7, a guide post 8, and a holding portion 9 that are connected in sequence. The positioning block 7 is used to fit and engage with the positioning hole 5. The guide post 8 is axially movably installed in the installation hole 6, and the holding portion 9 is located outside the installation hole 6.

[0042] In this technical solution, first, place the battery cell group to be stacked and press-fitted on the support slide rail 2 of the workbench 1. Then, move and adjust the position of the fixed stop block 3 according to the number of battery cells. Next, use the positioning and fixing component to position the fixed stop block 3 at a specified position on the support slide rail 2. One end of the battery cell group abuts against the fixed stop block 3, and the other end contacts the output end of the pressing mechanism. Then, the output end of the pressing mechanism applies pressure to the battery cell group, causing the battery cell group to be stacked and shaped. Finally, use a steel belt to wind and bind to complete the formation of the battery cells into a group.

[0043] The working principle of the positioning and fixing component: As Figure 2 shown, when the fixed stop block 3 moves and adjusts its position, the guide post 8 is pulled by the holding portion 9 to move in the installation hole 6 of the fixed stop block 3, making the positioning block 7 move away from the positioning hole 5. At the same time, the reset member 4 deforms. After the fixed stop block 3 moves to the specified position, the positioning hole 5 and the installation hole 6 are aligned, and the reset member 4 resets and pushes the positioning block 7 to move so that the positioning block 7 engages with the positioning hole 5 of the support slide rail 2, thereby realizing the connection and fixation between the fixed stop block 3 and the support slide rail 2.

[0044] Through the above structural design, it is convenient for the staff to adjust and move the fixed stop block 3 according to the number of battery cells to be grouped, realizing the quick change of the battery cell stacking and forming device, reducing the change time, and thus effectively improving the production efficiency.
