The two first clamps 211 are arranged opposite to each other along a first direction, and at least one of the first clamps 211 can move along the first direction. The first direction is the length direction of the battery cell 22 .

[0050] In the embodiment of the present application, the first grouping mechanism 210 is configured as a mechanism for grouping the battery cells 22 in the first direction. Figure 4 When a plurality of battery cells 22 are distributed side by side in the first direction (in the Y direction as shown in the figure), the two first clamping blocks 211 clamp each battery cell 22 along the first direction so that both sides of each battery cell 22 in the first direction are flush.

[0051] Through the above arrangement, at least one first clamping block 211 can move along the first direction, so that the relative positions of the two first clamping blocks 211 in the first direction are changed, thereby achieving the grouping of the battery cells 22 in the first direction.

[0052] According to some embodiments of this application, please refer to Figure 4 The first matching mechanism 210 further includes a first driving member, which is connected to at least one first clamping block 211 and is used to drive the first clamping block 211 to move.

[0054] In the embodiment of the present application, the first driving member is configured as a component for driving the first clamping block 211 to move, and the first driving member may be a motor, a cylinder or other driving structure that can provide driving force.

The side of the battery cell 22 in the first direction is a plane, and the first grouping positioning surface 211a is a planar structure to fit the side of the battery cell 22.

[0058] Through the above arrangement, the first assembly positioning surface 211 a of the first clamping block 211 is a planar structure to match the battery cell 22 and enhance the fit when assembling the battery cell 22 .

[0059] According to some embodiments of this application, please refer to Figure 5 , each first clamping block 211 extends along a second direction intersecting with the first direction; in the second direction, the size L1 of each first clamping block 211 is equal.

[0060] It should be noted that the second direction is Figure 5 The Y direction is the thickness direction of the battery cell 22. The size of the first clamping block 211 in the second direction is the length L1 of the first clamping block 211, and the size of the battery cell 22 in the second direction is the thickness of the battery cell 22.

For example, the two first clamps 211 are rectangular, and the lengths of the two first clamps 211 are greater than the thicknesses of at least two battery cells 22. In this way, the two first clamps 211 can group at least two battery cells 22 at one time, which is beneficial to improving the grouping efficiency of the battery cells 22.

[0062] Through the above arrangement, in the second direction, the sizes of the first clamping blocks 211 are equal, which is convenient for batch processing and rapid installation.

[0066] Through the above arrangement, at least one second clamping block 221 can move along the first direction, so that the relative positions of the two second clamping blocks 221 in the second direction are changed, thereby achieving the grouping of the battery cells 22 in the second direction.

[0067] According to some embodiments of this application, please refer to Figure 4 The first matching mechanism 210 further includes a second driving member 222 , which is connected to at least one second clamping block 221 , and is used to drive the second clamping block 221 to move.

[0068] It should be noted that the second driving member 222 is connected to at least one second clamping block 221, which can be understood as: each second driving member 222 is connected to only one second clamping block 221, that is, each second clamping block 221 is driven by a different driving member; each second driving member 222 is connected to two second clamping blocks 221 at the same time, that is, each second clamping block 221 is driven by the same driving member, so as to simplify the overall structure of the second matching mechanism 220.

[0072] In an embodiment of the present application, when the battery cells 22 are grouped, the second grouping positioning surface 221a is used to contact the side of the battery cell 22 in the second direction. The side of the battery cell 22 in the second direction is a plane, and the second grouping positioning surface 221a is a planar structure to fit the side of the battery cell 22.

[0073] In the embodiment of the present application, the two second clamping blocks 221 have the same shape and size. For example, the two second clamping blocks 221 are both in the shape of a cuboid and have the same size in the second direction.

[0074] Through the above arrangement, the second assembly positioning surface 221 a of the second clamping block 221 is a planar structure to match the battery cell 22 and enhance the fit when assembling the battery cell 22 .

[0084] It can be understood that when the pressing mechanism 300 presses the battery cell 22, the pressing block 320 is pressed on top of the battery cell 22, and the support 350 is moved upward by the thrust of the pressing block 320. At this time, the elastic member 330 can provide a buffering effect for the pressing block 320 to prevent the pressing force of the pressing block 320 on the battery cell 22 from being too large and causing the loss of the battery cell 22.

[0085] In the embodiment of the present application, the fixing plate 340 is configured as a component connecting the pressing driving member 310 and the pressing block 320, and the fixing plate 340 is provided with an avoidance hole for the support 350 to pass through. The fixing plate 340 can be a square plate, a circular plate or other irregularly shaped plate structure.

[0086] In an embodiment of the present application, the pillar 350 and the lower pressure block 320 can be an integral structure, for example, the two are integrally formed by injection molding or casting; or, the pillar 350 and the lower pressure block 320 can also be a split structure, for example, the two can be connected by welding or riveting.

[0087] In the embodiment of the present application, the elastic member 330 is a spring, and the number of the elastic member 330 is not limited to one, that is, at least two elastic members 330 can be arranged between the fixing plate 340 and the lower pressing block 320 .

[0088] Through the above arrangement, the elastic member 330 can provide a buffering effect for the lower pressing block 320 , thereby preventing the lower pressing block 320 from exerting an excessively large pressing force on the battery cell 22 and thereby preventing the battery cell 22 from being lost.

[0089] According to some embodiments of this application, please refer to Figure 3 The pairing device 30 includes at least two pairing units 200 , each pairing unit 200 is arranged side by side and shares a pressing mechanism 300 , and the number of pressing blocks 320 of the pressing mechanism 300 is set corresponding to the number of the pairing units 200 .

[0090] It should be noted that each of the grouping units 200 can group the battery cells 22 respectively. In particular, each of the grouping units 200 can operate synchronously to synchronously group the battery cells 22.

[0091] In the embodiment of the present application, each pairing unit 200 is arranged side by side and spaced apart in the same direction to facilitate the pairing operation.

[0094] It should be noted that the detection area is located downstream of the assembly area, which can be understood as: when the battery cell 22 is processed, it first passes through the assembly area and then passes through the detection area.

[0095] In the embodiment of the present application, the power detection device is configured as a component for detecting the power of the battery cell 22 .

[0096] In the above-mentioned battery production system, when grouping battery cells 22, the carrier 100 is used to carry and transport the battery cells 22, and each grouping mechanism is used to group the battery cells 22. At this time, the two clamps of the same grouping mechanism cooperate to clamp each battery cell 22. When the number and size of the battery cells 22 clamped between the two clamps change, the spacing between the two clamps can be adjusted to adapt to different numbers and sizes of battery cells 22, thereby improving the versatility of the grouping unit 200 and facilitating cost savings.
