[0036] Next, in combination with the specific implementation manner of the present utility model, the technical solutions in the present utility model will be clearly and completely described. Obviously, the described implementation manners are only a part of the implementation manners of the present utility model, rather than all the implementation manners. Based on the implementation manners in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0037] As Figures 1-6 shown, a battery module stacking tool of the present utility model includes a base plate 1, a guide rail 2, a fixed frame 3, a support frame 4, an end plate frame 5, a fixing component 6, an extrusion cylinder 7, and two side extrusion mechanisms 8.

[0038] Among them, the base plate 1 is used to carry other components.

[0039] The guide rail 2 is a guiding member of this stacking tool and also one of the core components for adaptively adjusting the length of the battery module according to the length of the battery module. The guide rail 2 is fixedly arranged on the base plate 1.

[0040] The fixed frame 3 is used to hold the end plate at one end of the battery module.

[0041] The support frame 4 is used to support multiple battery cells in the battery module.

[0042] The end plate frame 5 is used to pre-fix the end plate at the other end of the battery module.

[0043] The fixing component 6 is used to fix the fixed frame 3, the support frame 4, and the end plate frame 5, such as Figure 1As shown, the fixing frame 3, the support frame 4, and the end plate frame 5 are sequentially abutted and connected along the length direction of the guide rail 2, so as to provide good support for the end plate and the battery cells above them. Usually, there are 8-16 battery cells in the battery module, resulting in differences in the length of the battery module. The fixing frame 3, the support frame 4, and the end plate frame 5 are all slidably arranged on the guide rail 2. The support frame 4 has one or multiple support frames arranged along the length direction of the guide rail 2. By using the sliding fit between the fixing frame 3, the support frame 4, the end plate frame 5 and the guide rail 2, and adjusting the number of support frames 4 used, this stacking tooling can be adapted to battery modules of different lengths. After the fixing frame 3, the support frame 4, and the end plate frame 5 are moved to the appropriate positions on the guide rail 2, the fixing frame 3, the support frame 4, and the end plate frame 5 are fixedly connected to the guide rail 2 through the fixing component 6.

[0044] The fixing component 6 includes a slide bar 61, a first bolt 62, a second bolt 63, and a third bolt 64. As Figure 2 and Figure 3 shown, a fixing groove 201 is formed on the guide rail 2. The slide bar 61 is slidably arranged in the fixing groove 201. The first bolt 62 is threadedly connected to the slide bar 61 and abuts against the side of the support frame 4 or the end plate frame 5 away from the guide rail 2. When the first bolt 62 is loosened, the abutting force of the first bolt 62 on the support frame 4 or the end plate frame 5 and the abutting force between the slide bar 61 and the guide rail 2 can be reduced, so that the first bolt 62, the slide bar 61, and the support frame 4 or the end plate frame 5 can slide on the guide rail 2. When the first bolt 62 is tightened, the abutting force of the first bolt 62 on the support frame 4 or the end plate frame 5 and the abutting force between the slide bar 61 and the guide rail 2 can be increased, so that the first bolt 62, the slide bar 61, and the support frame 4 or the end plate frame 5 are fixed on the guide rail 2, respectively realizing the sliding and fixing of the support frame 4 and the end plate frame 5. At the same time, since the support frame 4 and the end plate frame 5 are the components that are adjusted most frequently in this stacking tooling, the sliding and fixing of the support frame 4 through the cooperation of the slide bar 61 and the first bolt 62 can improve the adjustment stability of this stacking tooling.

[0045] A plurality of fixing holes 202 are formed on the guide rail 2. The second bolt 63 is arranged in some of the fixing holes 202 and is threadedly connected thereto, and the second bolt 63 abuts against the side of the fixing frame 3 away from the guide rail 2, so as to fix the fixing frame 3 to the guide rail 2.

[0046] In order to improve the abutting effect of the fixing frame 3 on the end plate, the fixing frame 3 can also be fixed to the bottom plate 1. As Figure 2 shown, the third bolt 64 is threadedly connected to the bottom plate 1 and abuts against the side of the fixing frame 3 away from the guide rail 2.

[0047] The extrusion cylinder 7 is used to extrude the end plates on the end plate rack 5 so as to extrude and shape the battery module. The extrusion cylinder 7 is fixedly arranged on the bottom plate 1, and the extrusion cylinder 7 is located on the side of the end plate rack 5 away from the fixed rack 3. When the telescopic end of the extrusion cylinder 7 extends, the battery module can be extruded and shaped so as to sleeved the steel strip on the outside of the battery cells and the end plates.

[0048] The side extrusion mechanism 8 is used to extrude the side of the battery module. As Figure 5 shown, the side extrusion mechanism 8 is fixedly arranged on the bottom plate 1. There are two of them, and the two side extrusion mechanisms 8 are respectively arranged on both sides of the guide rail 2 to align multiple battery cells and end plates.

[0049] In order to make this stacking tooling adapt to battery modules of different lengths or different specifications, the positions of the various components in this stacking tooling can be adjusted. As Figure 2 shown, a plurality of mounting holes 101 are formed in the bottom plate 1. The guide rail 2, the third bolt 64 and the side extrusion mechanism 8 are fixedly connected to some of the mounting holes 101, thereby improving the adaptability of this stacking tooling.

[0050] As Figure 4 shown, the fixing groove 201 includes a sliding portion 2011, a supporting portion 2012 and a necking portion 2013. The necking portion 2013, the sliding portion 2011 and the supporting portion 2012 are connected in sequence; the cross section of the supporting portion 2012 is in an isosceles trapezoid shape, and the inner diameter of the supporting portion 2012 at one end close to the sliding portion 2011 is larger than the inner diameter of its end away from the sliding portion 2011, that is, the cross section of the supporting portion 2012 is in an inverted trapezoid shape, which can provide good support for the bottom side of the slide bar 61 to avoid the slide bar 61 pressing and damaging other components in the fixing groove 201 and the guide rail 2, and improving the structural strength of the guide rail 2; the inner diameter of the necking portion 2013 is smaller than the inner diameter of the sliding portion 2011, so that when the first bolt 62 is tightened, the slide bar 61 can abut against the connecting wall between the sliding portion 2011 and the necking portion 2013 to prevent the slide bar 61 from detaching from the fixing groove 201.

[0051] And in order to improve the connection stability of the various components in the stacking tooling, it is preferred that a plurality of fixing grooves 201 are provided. The plurality of fixing grooves 201 are arranged in parallel and at intervals, and at least one slide bar 61 is slidably arranged in each fixing groove 201.

[0052] As Figure 6As shown in the figure, the side extrusion mechanism 8 includes a base 81, a lead screw 82 and a pressing plate 83. Among them, the base 81 is fixedly arranged on the bottom plate 1; the lead screw 82 is rotatably arranged on the base 81; the pressing plate 83 is slidably arranged on the base 81 and is connected with the lead screw 82 through a threaded fit. When the lead screw 82 is rotated, by using its threaded fit with the pressing plate 83, the pressing plate 83 is pushed to move towards or away from the battery cell, so as to squeeze and align the side of the battery cell.

[0053] The usage method of a battery module stacking tooling of the present utility model is as follows:

[0054] First, select the number of support frames 4 and arrange the positions of the fixed frame 3, the support frame 4 and the end plate frame 5 according to the length of the battery module to be processed. Then, install one end plate of the battery module on the end plate frame 5, place the other end plate on the support frame 4 and abut it against the fixed frame 3. Alternately arrange a plurality of battery cells and heat insulation pads on the support frame 4 and between the two end plates. Then, by rotating the lead screw 82, the pressing plate 83 is used to hold the two sides of the battery cell module, so as to align the battery cells, end plates and heat insulation pads. Finally, by extending the telescopic end of the extrusion cylinder 7 to squeeze the end plate on the end plate frame 5. After the battery cells, end plates and heat insulation pads are squeezed in place, a steel belt can be sleeved on the outside of them.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
