In order to ensure that the battery module can be smoothly put into the box, part of the bottom area of ​​the battery module is generally reserved; at this time, the extrusion plane of the extrusion tooling only faces about 2 / 3 of the upper part of the battery module. When the bottom 1 / 3 area of ​​the battery module enters the box, the extrusion tooling will be removed, and the top of the battery module will be pressed with a pressing tool to force the battery module into the box.

The following is a detailed description of the thickness direction X1 of the battery cells being parallel to the length direction X2 of the box body (combined with Figure 1 As shown, the length direction of the battery cell is Y1; the width direction of the battery cell is Z1).

[0075] Specifically, the extrusion tooling includes a downward pressing mechanism and a side pressing mechanism.

[0076] Wherein, the side pressure mechanism includes: Figure 2 As shown, the first direction here refers to the length direction X2 of the box. Figure 2 The figure also shows the first side pressing part 3 and the second side pressing part 4 which are arranged in a width direction Y2 of the box body and a height direction Z2 of the box body, as shown in FIG. Fig. 9As shown, an extrusion space 33 is formed between the first and second side pressure portions relative to each other, and the extrusion space 33 can place the battery module, so that the first side pressure portion 3 and the second side pressure portion 4 can respectively abut against the extrusion surface 5 of the battery module, and the extrusion surface 5 here is the two end surfaces of the battery module in the first direction, that is, one of the first side pressure portion 3 and the second side pressure portion 4 can abut against the first end surface of the battery module in the first direction (the first end surface here can be understood as the exposed surface of the battery cell 1 at the first end portion arranged along the first direction, the surface formed by the length and width of the battery cell 1, that is, Figure 2 The left side exposed surface of the leftmost battery cell 1 in the battery module), and the other can abut against the second end surface of the battery module opposite to the first end surface in the first direction (the second end surface here can be understood as the exposed surface of the battery cell 1 at the second end opposite to the first end arranged along the first direction, the surface formed by the length and width of the battery cell 1, that is, Figure 2 The right side of the battery cell 1 at the rightmost end is exposed).

[0077] The pressing mechanism is disposed above the extrusion space 33, and the pressing mechanism can abut against the pressing surface 6 of the battery module. The pressing surface 6 is an end surface of the battery module perpendicular to the first direction. The pressing surface 6 can be understood as a surface composed of the length and thickness of multiple battery cells 1 arranged along the first direction. Figure 2 The upper end surface of the battery module.

[0078] In the actual working process: when the pressing mechanism presses down the battery module to load it into the box body 2, the first side pressure part 3 acts on the first end face, and the first side pressure part 3 continues to give a preset pressure to the first end face toward the second side pressure part 4, and the second side pressure part 4 acts on the second end face, and the second side pressure part 4 continues to give a preset pressure to the second end face toward the first side pressure part 3, so that the battery module is loaded into the box body 2 with a preset size.

[0079] In summary, in the present application, when the battery module is installed in the box body 2, the pressing mechanism provides a downward pressure on the battery module. During the pressing process, the first side pressing part 3 and the second side pressing part 4 continuously apply a preset pressure to the battery module in the first direction, so that the battery module can move along the Figure 3 The battery module is installed into the box body 2 in the vertical direction. During the packaging process, the battery module will not have a trumpet-shaped problem due to uneven force, thereby avoiding damage to the battery monomer.

[0080] In this embodiment, specifically, the pressing mechanism has a first driving part and a pressing part connected to the first driving part, the pressing part can abut against the pressing surface 6, and the first driving part drives the pressing part to abut against the pressing surface 6 to press the battery module into the box body 2.

[0081] Specifically, the first side pressure portion 3 and the second side pressure portion 4 are respectively provided with a second driving portion and a side pressure portion connected to the second driving portion, and the side pressure portion can abut against the extrusion surface 5. When the first driving portion drives the downward pressure portion to press the battery module down to load it into the box body 2, the second driving portion can drive the side pressure portion to abut against and continuously extrude the battery module by rolling.

[0082] In summary, when the first driving unit drives the pressing unit to press the battery module downward to load it into the box body 2, the second driving unit continuously applies a preset pressure to the first end surface toward the second side pressure unit 4 through the side pressure unit (the second driving unit and the side pressure unit here refer to the first side pressure unit 3). At the same time, the second driving unit continuously applies a preset pressure to the second end surface toward the first side pressure unit through the side pressure unit (the second driving unit and the side pressure unit here refer to the second side pressure unit 4), so that the battery module can be moved along the box body 2. Figure 3 The battery module is installed into the box body 2 in the vertical direction. During the packaging process, the battery module will not have a trumpet-shaped problem due to uneven force.

[0083] In this embodiment, the second driving part is an extrusion motor 10 , and the side pressure part is a rolling assembly 31 .

[0084] Specifically, the rolling assembly 31 has a fixed surface and a rolling surface that are relatively arranged. The fixed surface is connected to the extrusion motor 10, and the rolling surface is used to abut against the extrusion surface 5; an extrusion space 33 is formed between the rolling surface of the first side pressure part and the rolling surface of the second side pressure part.

[0085] More specifically, the rolling assembly 31 includes a roller member 32 , a side pressure plate 14 , and a bracket 15 .

[0086] There are two brackets 15 , which are spaced apart and have mounting holes correspondingly formed on opposite surfaces of the two brackets 15 .

[0087] The roller member 32 is installed between the two brackets 15 through the mounting holes 38 and the bolts 24. Fig. 9 As shown, five mounting holes 38 are spaced apart along the length direction of the bracket 15 , and the five mounting holes 38 on the two brackets 15 correspond to each other one by one.

[0088] Among them, the roller components 32 are provided in plurality, and the plurality of roller components 32 are arranged along Figure 4 The vertical direction of the spaced arrangement between the two brackets 15; combined Figure 4 , Figure 5 as well as Figure 7 , a situation of five roller components 32 is given (the five roller components 32 correspond exactly one to one to the five mounting holes); the surfaces of the five roller components 32 facing the battery module jointly form a rolling surface.

[0089] The two ends of the side pressure plate 14 are fixed to the side of the bracket 15 away from the battery module, and the side of the side pressure plate 14 facing the extrusion motor 10 has a mounting portion capable of mounting the output end of the extrusion motor 10. Figure 4 and Figure 8 As shown, the mounting portion is preferably a mounting tube, and the axial direction of the battery module is parallel to the first direction. Figure 8 As shown, the two ends of the side pressure plate 14 are provided with connection holes 39, Fig. 9 As shown, a round hole 23 is opened on one side of the bracket 15 facing the side pressure plate, and the side pressure plate 14 can be fixed to the two brackets 15 by passing a bolt 24 through the connecting hole 39 and the round hole 23. It is worth noting that the shape of the side pressure plate 14 is not limited to Figure 8 The rectangle in the figure, other shapes are also within the protection scope of this application.

[0090] Furthermore, combined with Figure 6 and Figure 7 As shown, the roller component 32 includes a roller 7 , a limiting sleeve 11 and a roller 12 .

[0091] Among them, the roller 12 passes through the roller 7 and is connected to the bracket 15; the limiting sleeve 11 is sleeved on the roller 12 and is located between the roller 7 and the bracket 15; further, the roller 12 is provided with a threaded hole 22 at the end along its length direction, and the bolt 24 passes through the bracket 15, the limiting sleeve 11 and the threaded hole 22 in sequence to be connected, so that the roller component 32 is fixed to the bracket 15.

[0092] Among them, the circumferential side wall of the roller 7 rolls against the two end faces of the battery module in the first direction, that is, in the process of using the second driving unit to drive the roller member 32 to apply force toward the first end face, since the first driving unit also applies a downward force to the battery module, the circumferential side wall of the roller 7 rolls against the two end faces of the battery module in the first direction, which reduces the friction between the two end faces of the battery module and the first side pressure part and the second side pressure part, so that the battery module can move downward smoothly under pressure. In addition, this rolling abutment method can reduce the damage to the end face of the battery module to a certain extent. For reference, the process of the battery module outside the box 2-part of the battery module is pressed down to the box 2-the battery module is completely pressed down into the box 2 is given.

[0093] Furthermore, combined with Fig.17 As shown, in order to prevent the roller from damaging the battery module, the battery module is further provided with a buffer pad 21 between the surfaces in contact with the roller.

[0094] In this embodiment, combined Figure 10-Figure 20 As shown, the first driving part is a pressing motor 8, and the pressing part includes a pressing plate 9 and a sponge suction cup.

[0095] Specifically, the driving end of the pressing motor 8 is connected to the pressing plate 9 ; the sponge suction cup is arranged on the side of the pressing plate 9 facing the battery module to adsorb the pressing surface 6 of the battery module.

[0096] More specifically, the pressing motor 8 has a telescopic piston cylinder, a piston rod of which is connected to the pressing plate 9 , and the piston rod moves downward to drive the pressing plate 9 to press the battery module until the battery module enters the box body 2 .

[0097] More specifically, combined with Fig.16 As shown, a lower pressing plate limiting protrusion 25 is formed on one side of the lower pressing plate 9 facing the battery module; when the pressing mechanism presses the battery module down to load it into the box body 2, the lower pressing plate limiting protrusion 25 can avoid the pole 34 of the battery module to abut against the lower pressing surface 6 (combined with Fig.16 As shown, a battery cell shoulder 26 is formed between the pole 34 and the end of the battery cell, the pole 34 is arranged on the shoulder 26, and the height of the lower pressure plate limiting protrusion 25 is greater than the height of the pole 34, so that when the lower pressure plate limiting protrusion 25 is used to press down the battery module, the lower pressure plate limiting protrusion 25 acts on the battery cell shoulder 26 to avoid crushing the pole 34).

[0098] In this embodiment, the extrusion tool further includes a truss 13 and a crossbeam 16 .

[0099] Specifically, the cross beam 16 is slidably arranged on the truss 13 along the length direction X2 of the box body to change the position of the cross beam 16 on the truss 13; the pressing mechanism is arranged on the cross beam 16, and the change of the position of the cross beam 16 on the truss 13 can drive the pressing mechanism to move, thereby changing the position of the pressing mechanism on the cross beam 16, and then changing the position of the pressing mechanism acting on the top surface of the battery module, so as to adjust the position of the pressing mechanism as needed, thereby realizing free adjustment of the pressing position.

[0100] More specifically, the extrusion tooling further includes an extrusion frame, and the extrusion frame includes a fixing rod 17 and a connecting frame 18 .

[0101] The connecting frame 18 is arranged above the box body 2 along the length direction X2 of the box body, and is combined with Fig.10 As shown, a support leg 27 is provided at the bottom of the connecting frame 18, and the support leg 27 is used to support the connecting frame 18 above the box body 2. The two ends of the connecting frame 18 are respectively connected to the first side pressure part and the second side pressure part to fix and position the side pressure mechanism; the top of the connecting frame 18 is connected to the cross beam 16 through the fixing rod 17; thereby, the side pressure mechanism and the downward pressure structure are integrated into one, the structure is simplified, and the operation of the side pressure mechanism is also facilitated.

[0102] Among them, the connecting frame 18 is provided with a through groove 37, and the driving end of the first driving part can pass through the through groove 37 to be connected with the lower pressure plate 9. The projection area of ​​the through groove 37 is smaller than the projection area of ​​the lower pressure plate 9 so that the lower pressure plate 9 is arranged between the connecting frame 18 and the battery module, thereby preventing the lower pressure plate 9 from moving upward from the through groove 37 and detaching from the connecting frame 18.

[0103] Furthermore, the connecting frame 18 includes a transverse plate 36 and a vertical plate 35 . The vertical plates 35 are vertically arranged at two ends of the transverse plate 36 along the first direction. The extrusion motor 10 passes through the vertical plates 35 to connect with the roller component.

[0104] Combination Fig.17 As shown, a PC sheet 20 is arranged between adjacent battery cells 1 .
