[0037] In the following, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and are not all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described herein.

[0038] Figure 1 A structure diagram of the formation and dispensing device provided by an exemplary embodiment of the present application. As shown in FIG. 1, the formation and dispensing device comprises a main frame 110, a bottom frame 111, a top frame 112, a guide column 113, a probe assembly 120, a movable frame 130, a cooling module 140 and a bearing member 150. Figure 1As shown, the formation and capacity device 100 provided by the embodiment of the present application can include a main frame 110 and a movable frame 130, and the movable frame 130 is slidably fitted in the main frame 110 along a first direction (indicated by arrows A and B). Figure 1 In an embodiment, the movable frame 130 can be driven to move along the first direction by a driving element such as a motor, an oil cylinder or a gas cylinder.

[0039] In an embodiment, the movable frame 130 can be driven to move along the first direction by a driving element such as a motor, an oil cylinder or a gas cylinder.

[0040] As shown, the formation and capacity device 100 can further include a probe assembly 120 and a plurality of carriers 150, and the probe assembly 120 is arranged on the main frame 110, and the carriers 150 are arranged on the movable frame 130. In actual application, the carriers 150 can be used to carry the battery cells, and the movable frame 130 moves along the first direction (for example, along the direction indicated by arrow A), which can drive the carriers 150 to move towards the direction close to the probe assembly 120, so that the probe assembly 120 and the battery cells in the carriers 150 abut each other, thereby assisting in subsequent formation and capacity process. After the capacity, the movable frame 130 moves along the first direction (for example, along the direction indicated by arrow B), which can drive the carriers 150 to move away from the probe assembly 120, so that the battery cells in the carriers 150 and the probe assembly 120 are separated from each other. Figure 1 It should be noted that during the process of abutting the battery cells and the probe assembly 120 to perform the formation and capacity process, the battery cells will generate heat, and the heat inside the carriers 150 cannot be effectively dissipated, which can easily cause the temperature of different parts of the battery cells to be uneven, and the local temperature to be too high, which can easily cause safety accidents. Therefore, as shown, the formation and capacity device 100 provided by the embodiment of the present application can further include a plurality of cooling modules 140, and the plurality of cooling modules 140 are connected with the main frame 110, and the cooling modules 140 are arranged between adjacent two carriers 150. The cooling modules 140 can cool and cool the adjacent two carriers 150, improve the heat dissipation efficiency of the carriers 150, avoid the heat from gathering in the carriers 150, thereby effectively improving the problem of uneven temperature and the problem of too high local temperature of the battery cells in the carriers 150 during the formation and capacity process, and effectively reducing the probability of safety accidents.

[0041] Figure 1 It should be understood that the cooling modules 140 are arranged between the two carriers 150, and the same cooling module 140 can simultaneously cool the adjacent two carriers 150, which can improve the utilization rate of the cooling modules 140, reduce the use amount of the cooling modules 140, and reduce the production cost.

[0042] It should be understood that the cooling modules 140 are arranged between the two carriers 150, and the same cooling module 140 can simultaneously cool the adjacent two carriers 150, which can improve the utilization rate of the cooling modules 140, reduce the use amount of the cooling modules 140, and reduce the production cost.

[0043] As shown, the formation and capacity device 100 provided by the embodiment of the present application can further include a probe assembly 120 and a plurality of carriers 150, and the probe assembly 120 is arranged on the main frame 110, and the carriers 150 are arranged on the movable frame 130. In actual application, the carriers 150 can be used to carry the battery cells, and the movable frame 130 moves along the first direction (for example, along the direction indicated by arrow A), which can drive the carriers 150 to move towards the direction close to the probe assembly 120, so that the probe assembly 120 and the battery cells in the carriers 150 abut each other, thereby assisting in subsequent formation and capacity process. After the capacity, the movable frame 130 moves along the first direction (for example, along the direction indicated by arrow B), which can drive the carriers 150 to move away from the probe assembly 120, so that the battery cells in the carriers 150 and the probe assembly 120 are separated from each other. Figure 1 ​As shown, the main frame 110 can include a bottom frame 111, a top frame 112, and guide columns 113. The top frame 112 is opposite to the bottom frame 111 along a first direction. The guide columns 113 are connected to the bottom frame 111 and the top frame 112 at opposite ends along the first direction. The movable frame 130 is slidingly fitted to the guide columns 113 along the first direction.

[0044] It should be understood that the guide columns 113 can guide the movable frame 130 to prevent the movable frame 130 from deviating from the first direction during movement of the movable frame 130 along the first direction.

[0045] As shown in the embodiment, Figure 1 the number of guide columns 113 is four. The four guide columns 113 are distributed at the four vertices of the rectangle. The movable frame 130 is slidingly fitted to the four guide columns 113. In this way, the stability of the movable frame 130 during sliding can be effectively improved, and the inclination of the movable frame 130 during movement can be avoided.

[0046] As shown in the embodiment, Figure 1 the cooling module 140 is arranged between the bottom frame 111 and the top frame 112. The cooling module 140 is connected to the bottom frame 111 and the top frame 112. On the one hand, the bottom frame 111 and the top frame 112 can serve as mounting carriers of the cooling module 140 to improve the assembly stability of the cooling module 140. On the other hand, the bottom frame 111 and the top frame 112 can protect the cooling module 140 from external objects.

[0047] In an embodiment, the cooling module 140 is arranged between the bottom frame 111 and the top frame 112. The cooling module 140 can be connected to one of the bottom frame 111 and the top frame 112.

[0048] As shown in the embodiment, Figure 1 the side of the top frame 112 facing the bottom frame 111 is provided with a support frame 1121. The probe assembly 120 is arranged on the support frame 1121. In this way, on the one hand, the support frame 1121 can support the probe assembly 120 to facilitate installation of the probe assembly 120. On the other hand, the support frame 1121 can protect the probe assembly 120 from other objects.

[0049] As shown in the embodiment, Figure 1As shown, in actual application, if formation and component distribution operation is needed, the movable rack 130 needs to be moved towards the probe assembly 120 arranged on the top rack 112, that is, the movable rack 130 needs to be moved towards the top rack 112. It should be understood that if the movable rack 130 is moved too close to the top rack 112, the pressing force between the probe assembly 120 and the battery cell can be too large, which can easily cause damage to the battery cell. Therefore, a limiting column 131 is arranged on the side of the movable rack 130 close to the top rack 112. When the movable rack 130 is moved to a predetermined position, the limiting column 131 abuts against the top rack 112, limiting the movable rack 130 from continuously moving towards the top rack 112. In this way, the abutment between the probe assembly 120 and the battery cell can be ensured, and at the same time, the abutment force between the probe assembly 120 and the battery cell can be avoided to be too large, effectively improving the problem that the battery cell is easily damaged by the probe assembly 120.

[0050] In an embodiment, the number of limiting columns 131 can be multiple, and the multiple limiting columns 131 are arranged on different positions of the movable rack 130.

[0051] Figure 2 A structural schematic view of the bottom rack and the cooling module is provided for an exemplary embodiment of the present application. Figure 3 A structural schematic view of the cooling module is provided for an exemplary embodiment of the present application. As shown in Figure 2 and Figure 3 As shown, the cooling module 140 can include a cooling member 141, an inlet pipe 142 and an outlet pipe 143. The cooling member 141 is arranged between two adjacent bearing members 150, and the cooling member 141 is connected with the bottom rack 111. The inlet pipe 142 and the outlet pipe 143 are both arranged on the bottom rack 111, and the inlet pipe 142 and the outlet pipe 143 are both in communication with the cooling member 141.

[0052] In actual application, the cooling medium (such as cold air, cooling liquid, etc.) enters the cooling member 141 through the inlet pipe 142. During the process of flowing through the cooling member 141, the cooling medium can absorb the heat emitted by the bearing member 150, and improve the problem of heat accumulation in the bearing member 150.

[0053] It should be noted that, in combination with Figure 1 , the cooling member 141 penetrates through the movable rack 130. In this way, the cooling member 141 will not interfere with the movement of the movable rack 130 along the first direction, and the smooth movement of the movable rack 130 along the first direction between the bottom rack 111 and the top rack 112 can be ensured.

[0054] As shown in Figure 2 and Figure 3As shown, the cooling member 141 can include a first converging member 1411, a second converging member 1412, and a plurality of connecting pipes 1413, the first converging member 1411 being in communication with the liquid inlet pipe 142, the second converging member 1412 being in communication with the liquid outlet pipe 143, and the plurality of connecting pipes 1413 being in parallel communication with the first converging member 1411 and the second converging member 1412.

[0055] Specifically, after the cooling medium enters from the liquid inlet pipe 142, it enters the first converging member 1411, is respectively distributed to different connecting pipes 1413 from the first converging member 1411, is then converged to the second converging member 1412 from the plurality of different connecting pipes 1413, and then enters the liquid outlet pipe 143 through the second converging member 1412 and is discharged from the liquid outlet pipe 143.

[0056] It should be understood that, on the one hand, the plurality of connecting pipes 1413 can simultaneously perform cooling operations on the bearing member 150, which can improve the heat dissipation efficiency of the bearing member 150; on the other hand, the plurality of connecting pipes 1413 can perform heat dissipation on different parts of the bearing member 150, which can improve the problem of local temperature overheat of the bearing member 150, thereby improving the problem of local temperature overheat of the battery cell in the bearing member 150, and making the temperature of the battery cell more uniform.

[0057] As shown in Figure 2 and Figure 3 , the plurality of connecting pipes 1413 are distributed in parallel along the first direction, so that the plurality of connecting pipes 1413 can respectively cool different parts of the bearing member 150 in the first direction, thereby improving the problem of local temperature overheat of the bearing member 150 and the battery cell.

[0058] In an embodiment, for the plurality of connecting pipes 1413 distributed in parallel along the first direction, the distance between any two adjacent connecting pipes 1413 along the first direction is the same, which can further improve the problem of local temperature overheat of the bearing member 150 and the battery cell.

[0059] As shown in Figure 2 , the liquid inlet pipe 142 and the liquid outlet pipe 143 are respectively arranged on opposite sides of the chassis 111 in the second direction (perpendicular to the first direction, refer to the directions indicated by arrows C and D in Figure 2 ).

[0060] As shown in Figure 2As shown, the bottom frame 111 includes a first connecting plate 1111 and a second connecting plate 1112 distributed oppositely, and the liquid inlet pipe 142 is clamped between the first connecting plate 1111 and the second connecting plate 1112. In this way, the first connecting plate 1111 and the second connecting plate 1112 can limit the liquid inlet pipe 142, preventing the liquid inlet pipe 142 from shaking or shifting, thereby ensuring the connection stability between the liquid inlet pipe 142 and the external liquid inlet device.

[0061] As shown, the bottom frame 111 includes a third connecting plate 1113 and a fourth connecting plate 1113 distributed oppositely, and the liquid outlet pipe 143 is clamped between the third connecting plate 1113 and the fourth connecting plate 1113. In this way, the third connecting plate 1113 and the fourth connecting plate 1113 can limit the liquid outlet pipe 143, preventing the liquid outlet pipe 143 from shaking or shifting, thereby ensuring the connection stability between the liquid outlet pipe 143 and the external liquid outlet device. Figure 2 The application further provides a formation and capacity production line, which comprises the formation and capacity device 100 and a conveying device. The conveying device can transfer a plurality of battery cells into the carrier 150, and then the movable frame 130 moves in the first direction to drive the carrier 150 and the battery cells to gradually approach the probe assembly 120 until the probe assembly 120 abuts against the battery cells.

[0062] It should be understood that the formation and capacity production line provided by the application includes all the functions of the formation and capacity device 100, and the beneficial effects thereof can refer to those of the formation and capacity device 100.
