Description

Technical Field

[0002] At present, the design of power battery packs, the core components of electric vehicles, is evolving towards lightweight and integration. Improving the space utilization efficiency, increasing the number of batteries per unit space, and reducing the number of components to increase the pure electric range of electric vehicles has become the mainstream in the field of electric vehicle battery pack design.

[0003] To achieve the above purpose, the current grouped cells and liquid cooling structural parts are generally directly integrated by gluing to achieve the dual effects of ensuring structural strength and reducing the weight of the battery pack. There is no longer a structural part between the grouped cells to control the stacking spacing of the cells. The distance between the cells is completely an air gap. This type of battery pack design can effectively achieve the purpose of weight reduction and improve space utilization efficiency.

[0004] The existing technical method for stacking air gaps between cells is to use a spacer with the same thickness as the air gap to adjust the gap between two cells, and then use an epoxy board with adhesive backing to temporarily control the gap between cells to ensure that the distance between several cells in a module does not change during the subsequent processing after stacking. However, this method can only adjust and stack the distance between two cells at a time, which is inefficient. In addition, a large amount of epoxy board consumables is required, and since the epoxy board needs to be disassembled for a second time and an additional temporary storage place is arranged when the product is manufactured, additional labor and storage costs are added.

[0049] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] Combine the following Figure 1-Figure 7 The utility model describes a battery cell gap adjustment device and a hot pressing device.

[0051] like Figure 1 As shown, a cell gap adjustment device provided by an embodiment of the utility model comprises: a module tray 1, a top adjustment mechanism 2 and a bottom adjustment mechanism 3; wherein,

[0052] A cell adjustment area is provided in the middle of the module tray 1, and an adjustment opening 10 is provided in the cell adjustment area;

[0053] The top adjustment mechanism 2 is arranged above the module tray 1 and can be fixed on a wall or other equipment body for fixing. Its action end can perform vertical linear movement toward the battery cell adjustment area. By inserting the action end between adjacent battery cells, the gap between the battery cells 4 can be adjusted.

[0054] The bottom adjustment mechanism 3 is arranged below the module tray 1 and can be fixed on the ground, wall or a fixable equipment body through a bracket structure; the bottom adjustment mechanism 3 has multiple adjustment ends that can adjust the spacing, each adjustment end can be raised and lowered in the vertical direction and passes through the adjustment opening 10. When the battery cell is placed on the adjustment end, the battery cell can be temporarily fixed, and the gap of the battery cell 4 can be adjusted by adjusting the spacing of the multiple adjustment ends.

[0055] The cell gap adjustment device and battery production equipment provided by the utility model form temporary fixing points of the cells in the cell adjustment area by inserting multiple adjustment ends of the bottom adjustment mechanism 3 into the cell adjustment area along the adjustment opening 10, and multiple cells are temporarily fixed. The first adjustment of the cell gap is achieved by adjusting the gap of the multiple adjustment ends of the bottom adjustment mechanism 3; then the top adjustment mechanism 2 drives the action end to move above the cell, and the second adjustment of the gap is performed on the top of the cell; after the adjustment is completed, the multiple adjustment ends of the bottom adjustment mechanism 3 exit the cell adjustment area, and the cell with the gap adjustment is placed on the module tray 1. There is no need to use epoxy board for auxiliary fixing throughout the process, which saves the raw material cost and equipment cost of loading and unloading brought by the use of epoxy board, and there is no process of disassembling, storing and reusing epoxy board, which can greatly reduce labor costs. Since the gap of multiple cells can be adjusted simultaneously by the bottom adjustment mechanism 3 and the top adjustment mechanism 2, the gap stacking efficiency of the cells can be greatly improved.

[0056] And because epoxy boards are not used, deformation of epoxy boards during disassembly, storage and transportation, which affects flatness, affects reuse effects, and leads to poor stability of the gap between battery cells, is avoided.

[0057] like Figure 1 As shown, in a preferred embodiment of the present invention, the module tray 1 is a long strip structure with a U-shaped cross section, and an adjustment opening 10 is opened on its bottom wall along the length direction, and the width of the adjustment opening 10 is smaller than the long side dimension of the battery cell.

[0058] In the above scheme, the adjusting end of the bottom adjustment mechanism 3 can be along the adjustment opening 10, and then withdrawn along the adjustment opening 10 after the gap adjustment is completed. During the withdrawal process, the long side of the battery cell 4 is larger than the width of the adjustment opening 10, and can then be lifted by the bottom wall of the module tray 1 to complete the gap adjustment on the module tray 1. This scheme can improve the convenience of gap adjustment and increase the processing frequency.

[0059] like Figure 1-3 As shown, in the preferred embodiment of the present utility model, the top adjustment mechanism 2 includes: a top displacement mechanism 20 and a gap partition assembly 21; wherein,

[0061] The top of the gap partition assembly 21 is detachably connected to the bottom of the action end of the top displacement mechanism 20, and the bottom of the gap partition assembly can be inserted into the gap of the battery cell 4 to achieve gap adjustment.

[0062] In the above scheme, the top displacement mechanism 20 drives downward through the gap partition assembly 21 to achieve the gap adjustment of the battery cell 4, and returns after completion to wait for the next adjustment. The action is simple, the controllability is strong, and the control accuracy is higher, which is conducive to ensuring the accuracy of the battery cell gap adjustment.

[0063] like Figure 1-3 As shown, in the preferred embodiment of the present utility model, the top displacement mechanism 20 includes: a fixed plate 200, an auxiliary base 201, a first linear driving component 202, and a guide frame 203; wherein,

[0064] The fixing plate 200 can be fixed on a wall or other equipment body for fixing, and is arranged above the module tray 1;

[0065] The auxiliary base 201 is a U-shaped plate frame, two of which are inverted and fixed at the upper ends of the fixed plate 200; an action area is formed between the opening area of ​​the auxiliary base 201 and the fixed plate 200;

[0066] The first linear driving component 202 may be an electric telescopic rod, a cylinder or the like, preferably a cylinder.

The guide rod at the bottom passes through the fixed plate 200 and is connected to the gap partition assembly 21. The guide rod is slidably connected to the fixed plate 200.

[0068] In the above scheme, the first linear drive component 202 can drive the guide frame 203 to move up and down in the vertical direction of the fixed plate 200, and then drive the gap partition assembly 21 to realize the battery cell gap adjustment action. The guiding effect of the guide frame 203 can further ensure the stability of the lifting action, reduce the adjustment error, and ensure the accuracy of the gap adjustment.
