[0070] In one embodiment, as Figure 2 and Figure 3 shown, the first base 260 is further provided with a second limiting hole 264, and the second end of the guide rail assembly 320 passes through the second limiting hole 264 and is connected to the second adjusting plate 220.

[0071] Among them, the guide rail assembly 320 can include a plurality of guide rail rods. For example, the guide rail assembly 320 can include two guide rail rods, and the guide rail rods can adopt precision guide rods.

[0072] The second limiting hole 264 of the first base 260 is a through hole. The second end of the guide rail assembly 320 passes through the second limiting hole 264, and the second end of the guide rail assembly 320 is connected to the second adjusting plate 220. Then, when the air cylinder 310 starts to work, the guide rail assembly 320 is driven to move in the first direction through the transmission rod. Further, the guide rail assembly 320 can move within the second limiting hole 264, and successively drives the second adjusting plate 220, the first adjusting plate 210, and the edge ironing module to move in the first direction, so as to control the ironing head module 10 to abut against the corresponding side seal 610 of the battery cell, thereby reducing the friction during the movement and improving the accuracy of movement positioning.

[0073] In one embodiment, as Figures 4 to 6 shown, the ironing head module 10 includes an ironing head block 110; the ironing head block 110 has a first plate surface and a second plate surface. The first plate surface of the ironing head block 110 is used to fit against the side seal 610 of the battery cell and heat the side seal 610 of the battery cell; the second plate surface of the ironing head module 10 is used to arrange the angle adjusting assembly 20.

[0074] Among them, the ironing head block 110 is used to heat and shape the side seal 610 of the battery cell. The first plate surface of the ironing head block 110 is the ironing contact surface, and the second plate surface of the ironing head block 110 is the mounting surface.

[0075] Exemplarily, when performing the edge ironing operation on the battery cell, the angle adjusting assembly 20 can be controlled to rotate according to the model of the corresponding battery cell, and then the ironing head angle of the ironing head block 110 is adjusted through the angle adjusting assembly 20; the displacement adjusting module 30 is controlled to drive the angle adjusting assembly 20 to move in the first direction, and then the angle adjusting module drives the ironing head block 110 to move in the first direction, so that the first plate surface of the ironing head block 110 abuts against the side seal 610 of the battery cell, and the side seal 610 of the battery cell is completely attached to the battery cell body 620; the ironing head block 110 is controlled to heat the side seal 610 of the battery cell, so that the side seal 610 of the battery cell is tightly combined with the battery cell body 620, realizing the side sealing of the side seal 610 of the battery cell and the battery cell body 620, and improving the production yield and production efficiency of the battery cell.

[0076] In one embodiment, as Figure 4 and Figure 5 shown, the ironing head block 110 is provided with a receiving cavity, and a heating element 120 is arranged in the receiving cavity.

[0077] Among them, the heating element 120 can be but is not limited to a resistive heating element 120. The heating element 120 can be arranged in the receiving cavity by means of snap connection or screw connection, etc.

[0078] For example, the heating element 120 is connected to the controller. When it is necessary to heat the side seal 610 of the battery cell, the controller supplies power to the heating element 120, and then the heating element 120 heats the side seal 610 of the battery cell through the first surface of the heating head block 110, so as to realize that the side seal 610 of the battery cell is completely bonded to the battery cell body 620, and avoid the side seal 610 of the battery cell from opening when the edge is being heated due to incomplete fitting between the side seal 610 of the battery cell and the battery cell body 620.

[0079] Exemplarily, the heating head block 110 is further provided with a temperature sensor to monitor the temperature of the heating head block 110. When the monitored temperature is abnormal, an alarm is triggered to timely remind the operator to check and maintain.

[0080] In one embodiment, as Figure 2 and Figure 3 shown, the battery edge heating device further includes a heat insulation member 50; the heat insulation member 50 is disposed between the heating head module 10 and the angle adjustment assembly 20.

[0081] Among them, the heating head module 10, the heat insulation member 50 and the angle adjustment assembly 20 can be fixedly connected by bolts. The heat insulation member 50 is used to thermally isolate between the heating head module 10 and the angle adjustment assembly 20, so as to avoid scalding when the operator manually operates the angle adjustment assembly 20.

[0082] In one embodiment, a battery assembly system is further provided, including a controller and the battery edge heating device as described in any one of the above; the controller is connected to the battery edge heating device.

[0083] For the specific description content of the controller and the battery edge heating device, reference can be made to the specific description of the controller and the battery edge heating device in the above embodiments, and details are not described herein again.

[0084] Based on the battery edge heating device including a heating head module, an angle adjustment assembly and a displacement adjustment module, the controller is electrically connected to the heating head module and the displacement adjustment module. The angle adjustment assembly is disposed on the heating head module, and the displacement adjustment module is connected to the angle adjustment assembly. The controller controls the heating head module to heat the side seal of the battery cell; the angle adjustment assembly is used to adjust the heating head angle of the heating head module; the controller controls the displacement adjustment module to drive the heating head module to move through the angle adjustment assembly, so as to make the heating head module abut against the side seal of the battery cell, and make the corresponding battery cell body fit with the side seal of the battery cell, so as to be able to adjust and adapt the corresponding edge heating angle according to different models of battery cells, and control the movement of the heating head module and heat the side seal of the battery cell, so as to realize the fitting of the corresponding side seal of the battery cell and the battery cell body.

[0085] In the above embodiments, by providing an angle adjustment component, the angle of the ironing head module can be adjusted according to different types of battery cells by controlling the angle adjustment component, so as to achieve adaptation to the corresponding edge ironing angle; the ironing head module is controlled to move by the displacement adjustment module, so that the ironing head module after angle adjustment can abut against the side seal of the corresponding battery cell, and the heating function is started to heat the side seal of the battery cell, so that the side seal of the battery cell can be completely attached to the battery cell body, avoiding the opening of the side seal of the battery cell when ironing the edge due to incomplete attachment between the side seal of the battery cell and the battery cell body, preventing electrolyte leakage, improving the production yield and production efficiency of the battery cell, and improving the versatility of the battery assembly system.

[0086] It should be noted that the battery assembly system may further include components such as an alarm. Specifically, the battery assembly system may include more components than those described in the above embodiments, or combine certain components, or have different component arrangements.

[0087] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
