[0069] The specific embodiments of the present application will be further described in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0070] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0071] In the present application, unless otherwise explicitly specified and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0072] In the description of the present embodiment, the terms "up", "down", "right", and other orientation or position relationships are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0073] At present, in the cell stacking process of the new energy square shell module in the cell stacking section, the left end plate, the right end plate and the middle end plate in the group stacking are respectively assembled with the cells, and the pairing form is that the middle end plate, the left end plate and the right end plate are respectively stacked with the corresponding adjacent cells first, and then paired, and then the module is stacked. Such group logic is relatively complex, and there is a great limitation in compatibility when pairing. For example, if the PACK package of the power battery in a new energy vehicle is composed of multiple 1A1B type (the number of cells on both sides of the middle end plate is different) modules, it will cause great disturbance to the production line arrangement.

[0074] As shown in Figures 1-12 The embodiment provides a cell module group stacking equipment, which has a first direction X, a second direction Y and a third direction Z perpendicular to each other, and the third direction Z is the height direction of the cell module group stacking equipment. The cell module 100 includes a left end plate 1001, a first cell group 1002, a middle end plate 1003, a second cell group 1004 and a right end plate 1005. The first cell group 1002 and the second cell group 1004 each include a plurality of cells.

[0075] The cell module group stacking equipment includes a feeding device 1, a module grouping device 2 and a discharging device 3.

The second clamping mechanism 222 is used to clamp the second cell group 1004 along the second direction Y. The third clamping mechanism 223 includes a first driving member 2231 and a second driving member 2232. The first driving member 2231 is used to clamp the left end plate 1001 and the first cell group 1002 towards the middle end plate 1003. The second driving member 2232 is used to clamp the second cell group 1004 and the right end plate 1005 towards the middle end plate 1003, so as to form the cell module 100. The discharging device 3 is used to move the cell module 100 on the support platform 21 out of the module grouping device 2.

[0076] The battery cell module group stacking device provided by the embodiment is used for conveying the left end plate 1001, the middle end plate 1003, the right end plate 1005, the first battery cell group 1002 and the second battery cell group 1004 required for grouping the battery cell module 100 to the module grouping device 2 through the feeding device 1, and the left end plate 1001, the middle end plate 1003, the right end plate 1005, the first battery cell group 1002 and the second battery cell group 1004 are grouped on the module grouping device 2 to form the battery cell module 100, and the grouped battery cell module 100 is removed from the module grouping device 2 through the discharging device 3. When the module grouping device 2 groups the battery cell module 100, the first clamping mechanism 221 and the second clamping mechanism 222 clamp the first battery cell group 1002 and the second battery cell group 1004 along the second direction Y perpendicular to the first direction X, respectively, the first driving member 2231 of the third clamping mechanism 223 clamps the left end plate 1001 and the first battery cell group 1002 clamped in the first clamping mechanism 221 to the middle end plate 1003, and the second driving member 2232 of the third clamping mechanism 223 clamps the right end plate 1005 and the second battery cell group 1004 clamped in the second clamping mechanism 222 to the middle end plate 1003. This grouping mode makes the first battery cell group 1002 and the second battery cell group 1004 on both sides of the middle end plate 1003 have different structural sizes, so that the battery cell module group stacking device in the embodiment can meet the grouping work of the 1A1B type battery cell module 100, and by adjusting the first driving member 2231, the second driving member 2232, the first clamping mechanism 221 and the second clamping mechanism 222, the production of different models of 1A1B type battery cell modules 100 can also be very convenient.
