Description

Technical Field

[0001] This disclosure relates to the field of battery technology, and more specifically, to a battery cell assembly tooling. Background Technology

[0002] Large-area liquid cooling technology for battery packs is an advanced battery thermal management technology. By installing liquid cooling plates or pipes on the wide sides of the cell assembly, the cooling material can directly or indirectly contact each cell, thus achieving a more uniform cooling effect. Moreover, compared to traditional bottom liquid cooling, large-area liquid cooling offers a larger heat exchange area, significantly improving heat dissipation efficiency and thereby enhancing battery safety and lifespan. However, current large-area liquid cooling solutions present greater challenges in cell assembly, and assembly precision needs improvement. Utility Model Content

The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0038] Unless otherwise specified or stated, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “a,” “an,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “comprising” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to those listed; the terms “first” and “second” are used only as illustrative marks and are not intended to limit the number, importance, or order of the objects.

[0039] The terms “connection” and “fixation” should be interpreted broadly. For example, “connection” can be a fixed connection, a movable connection, an integral connection, or a detachable connection. It can be a direct connection or an indirect connection through an intermediate medium.

[0040] The phrase "part A is located on part B" as described in this disclosure can mean that part A is directly connected to part B, or that part A is located on part C, and part C is located on part B.

[0041] Furthermore, in this application, the orientation or positional relationship indicated by terms such as "upper / lower," "inner / outer," and "height" is based on the orientation or positional relationship shown in the accompanying drawings. It is used solely for the convenience of describing this disclosure and for simplification, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

It should be understood that these directional terms are relative concepts and can change accordingly depending on the orientation of the components placed in the accompanying drawings.

[0042] This disclosure provides a battery cell assembly assembly fixture, which can be used to assemble battery cell assemblies. (Reference) Figure 1 As shown, the battery cell assembly fixture includes: a base 1 and a first positioning block 2. The base 1 has a first positioning surface 101. The first positioning block 2 is stacked on the base 1 along a first direction. The first positioning block 2 has a second positioning surface 201 that is perpendicular to the first positioning surface 101. A spacer 21 is provided on the second positioning surface 201. The extension direction of the spacer 21 is perpendicular to the second positioning surface 201. The spacer 21 is perpendicular to the first positioning surface 101.

[0043] Figure 1 This diagram shows an overall schematic of the battery cell assembly tooling disclosed herein. Figure 4 A schematic diagram of an exemplary embodiment of the first positioning block 2 is shown.

[0044] The cell assembly tooling disclosed herein can be used for the assembly of prismatic cells in groups. When assembling prismatic cells in groups, refer to... Figure 6 As shown, multiple battery cells 72 can be first mounted on the liquid cooling plate 71 to form... Figure 6 The image shows a battery cell assembly, and then multiple... Figure 6 The shown cell assembly is assembled into the battery pack, and potting compound (such as thermally conductive silicone or liquid adhesive) is used to fill the gaps between the cells 72 and between the cells 72 and the liquid cooling plate 71. Using the assembly tooling provided in this disclosure, during the assembly process, the wide side of the cell 72 can be placed on the first positioning surface 101; the shoulder of the cell 72, i.e., the terminal side plane of the cell 72, abuts against the second positioning surface 201 of the first positioning block 2. The spacer 21 can control the assembly gap between the cells 72 mounted on its two sides, ensuring that the distance between the two cells 72 meets the potting compound gap requirements, thereby ensuring that the potting compound can be fully filled between the cells 72, strengthening and fixing the structure of the cells 72, and improving the heat dissipation performance of the battery pack.

[0045] In exemplary embodiments of this disclosure, reference is made for ease of description. Figure 1 As shown, in a direction perpendicular to the first positioning surface 101, i.e. Figure 1 The height direction is designated as the first direction / Z direction, and two orthogonal directions within a plane perpendicular to the first direction are designated as the second direction / X direction and the third direction / Y direction, respectively. Specifically, the direction perpendicular to the second positioning surface 201, i.e., the width direction in the figure, is designated as the second direction / X direction, and the direction perpendicular to the partition plate 21, i.e., the length direction in the figure, is designated as the third direction / Y direction.

[0046] It should be noted that, due to the upper limit of manufacturing process precision, the two directions described as "perpendicular" in this disclosure may not be a perfectly accurate 90°. For example, "perpendicular" can refer to a state where the angle formed by two straight lines is greater than 80° and less than 100°. As long as it is within the allowable error range of manufacturing precision, it should be considered perpendicular. Therefore, it can be further explained that the concepts of "coplanar," "parallel," and "symmetrical" mentioned in this disclosure are all within the allowable range of manufacturing process precision.

[0047] For example, during assembly, the liquid cooling plate 71 can be placed on the first positioning surface 101 first, and then the battery cell 72 can be installed on the liquid cooling plate 71. Alternatively, the battery cell 72 can be placed on the first positioning surface 101 first, and then the liquid cooling plate 71 can be placed on the battery cell 72. The first positioning surface 101 can provide planar positioning for the liquid cooling plate 71 or the battery cell 72, ensuring that the large surface of the battery cell 72 is stably attached to the liquid cooling plate 71.

[0048] Figure 2 A partial schematic diagram of an embodiment of a battery cell assembly fixture is shown, with incomplete structures indicated by double-dotted lines. (Reference) Figure 1 , Figure 2 as well as Figure 4As shown, in one exemplary embodiment of this disclosure, a spacer 21 is disposed in the non-edge region of the second positioning surface 201 to divide the second positioning surface 201 into a first positioning area 202 and a second positioning area 203. In this embodiment, when assembling the battery cells 72, the terminal side planes (shoulders of the battery cells 72) of two adjacent battery cells 72 can respectively abut against the first positioning area 202 and the second positioning area 203, and the assembly gap between them is controlled by the spacer 21 to ensure that the distance between the two battery cells 72 meets the requirements of the potting compound gap. Since two adjacent battery cells 72 share the same second positioning surface 201 for positioning, it is beneficial to further improve the assembly accuracy.

[0049] refer to Figure 1 , Figure 2 As shown, the first positioning blocks 2 can be arranged in pairs along the second direction, with the second positioning surfaces 201 of each pair of first positioning blocks 2 facing each other, and the spacers 21 of each pair of first positioning blocks 2 being coplanar. When installing the battery cell 72 onto the tooling, the terminal side plane of the battery cell 72 can abut against the second positioning surface 201 on either side along the X direction.

[0050] For example, the second positioning surface 201 is adjustable along the X and Y directions to accommodate different cell 72 sizes and installation positions. (See reference) Figure 2 , Figure 4 As shown, in an exemplary embodiment of this disclosure, the first positioning block 2 includes a first fixed block 22 and a first movable block 23; the first positioning block 2 is stacked on the base 1 along a first direction, and the first movable block 23 is adjustablely disposed on the first fixed block 22 along a second direction and a third direction; the second positioning surface 201 is located on the first movable block 23; the second direction is perpendicular to the second positioning surface 201; and the third direction is perpendicular to the partition plate 21.

[0051] The first movable block 23 is adjustablely positioned relative to the first fixed block 22 along the X and Y directions. For example, refer to... Figure 4 As shown, a first gasket 24 is provided between the first movable block 23 and the first fixed block 22 along the Y direction; a second gasket 25 is provided between the first movable block 23 and the first fixed block 22 along the X direction. The first gasket 24 and the second gasket 25 are detachably connected to the first fixed block 22, and the first movable block 23 is detachably installed on the first gasket 24 and the second gasket 25. When installing battery cells 72 of different sizes and with different installation requirements, the positions of the second positioning surface 201 and the spacer plate 21 in the X and Y directions can be adjusted by replacing the first gasket 24 and the second gasket 25 with different thicknesses.

[0052] For example, the spacer 21 is detachably disposed on the second positioning surface 201, and spacers 21 of different thicknesses can be replaced to meet different potting compound gap requirements. Alternatively, the spacer 21 is non-detachably disposed on the second positioning surface 201, and the potting compound gap requirements can be met by replacing the first movable block 23 of the spacer 21 with a different thickness.

[0053] refer to Figure 1 As shown, in one exemplary embodiment of this disclosure, at least two first positioning blocks 2 are provided along the Y direction. For example, there can be 6, 7, 8, or 9 first positioning blocks 2 along the Y direction. For example, for each first positioning block 2, a battery cell 72 is supported on the left and right sides of the spacer plate 21 along the Y direction. Alternatively, for each battery cell 72, its left and right ends along the Y direction are supported on a first positioning block 2. This embodiment can achieve the assembly of at least two battery cells 72 with the liquid cooling plate 71.

[0054] In one exemplary embodiment of this disclosure, the cell assembly tooling further includes a first clamping device 3. (See reference...) Figure 1 , Figure 2 as well as Figure 5 As shown, the first pressing device 3 has a pressure plate 31, which is movably arranged along the Z direction. The pressure plate 31 can be used to press the battery cell 72 to the liquid cooling plate 71, so that the battery cell 72 is firmly attached to the liquid cooling plate 71. For example, during assembly, the liquid cooling plate 71 can be placed on the first positioning surface 101 first, and then glue can be applied to the upper surface of the liquid cooling plate 71 or the release paper on the surface of the liquid cooling plate 71 can be removed to expose the backing adhesive, and then the battery cell 72 can be installed on the liquid cooling plate 71; or the glued battery cell 72 can be installed on the liquid cooling plate 71 with or without an adhesive layer, and the battery cell 72 can be firmly attached to the upper surface of the liquid cooling plate 71 by applying pressure to the battery cell 72 along the Z direction by the pressure plate 31. For example, the battery cell 72 can be placed on the first positioning surface 101 first, and then glue can be applied to the upper surface of the battery cell 72 or the release paper on the surface of the battery cell 72 can be removed to expose the back adhesive. Then, the liquid cooling plate 71 can be placed on the battery cell 72; or the glued liquid cooling plate 71 can be installed on the battery cell 72 with or without an adhesive layer, and the battery cell 72 can be firmly attached to the upper surface of the liquid cooling plate 71 by applying pressure to the liquid cooling plate 71 along the Z direction by the pressure plate 31.

[0055] In one exemplary embodiment, multiple first positioning blocks 2 are arranged along the Y direction, and the cell assembly fixture is used to assemble multiple cells 72 with the liquid cooling plate 71. There can be one pressure plate 31, which simultaneously presses all cells 72 together. For example, the first pressing device 3 is connected to a servo device, which can drive the pressure plate 31 along the Z direction to simultaneously press multiple cells 72 together, firmly attaching the cells 72 to the liquid cooling plate 71. Alternatively, the number of pressure plates 31 can be less than the number of cells 72, for example, one pressure plate 31 can simultaneously press two or more cells 72 together.

[0056] For example, the first pressing device 3 is arranged adjacent to the first positioning block 2 in a one-to-one correspondence along a third direction. For each battery cell 72, a first pressing device 3 can be provided, and each pressure plate 31 is used to correspond to one battery cell 72. This exemplary embodiment can be used for production scenarios with a variety of battery cells 72.

[0057] In one exemplary embodiment of this disclosure, reference is made to Figure 1 As shown, the battery cell assembly fixture also includes a second positioning block 4, which is stacked on the base 1 along the Z direction. The second positioning block 4 has a third positioning surface parallel to the second positioning surface 201. Using the assembly fixture provided in this disclosure, during the group assembly process, the side of the liquid cooling plate 71 can be pressed against the third positioning surface of the second positioning block 4 to position the liquid cooling plate 71 in the X direction.

[0058] For example, the second positioning block 4 is movably disposed along the X direction to accommodate different cell 72 sizes, liquid cooling plate 71 sizes, and relative mounting positions of the cell 72 and liquid cooling plate 71. For instance, the second positioning block 4 is slidably connected to the base 1 via a slide rail or groove, and can be driven to move along the X direction on the base 1 via a mechanism such as a lead screw nut or gear rack. Specifically, refer to... Figure 1 , Figure 2 As shown, the second positioning block 4 can be slidably connected to the base 1 via a lead screw and nut mechanism and a slide rail. By rotating the first handwheel 41 at one end of the lead screw, the second positioning block 4, which is threadedly connected to the lead screw, can be moved on the base 1 in the X direction.

[0059] In one exemplary embodiment of this disclosure, reference is made to Figure 1 , Figure 2 As shown, the second positioning blocks 4 are arranged in pairs along the second direction, with the third positioning surfaces of each pair of second positioning blocks 4 facing each other, and at least one of each pair of second positioning blocks 4 is movably arranged along the second direction.

[0060] For example, one of each pair of second positioning blocks 4 is movably disposed along the X direction, as described above regarding the movement of the second positioning blocks 4; the other can be fixedly disposed on the base 1. During assembly, the side of the liquid cooling plate 71 can be pressed against the third positioning surface of the fixed second positioning block 4, and then the movable second positioning block 4 can be adjusted to clamp the liquid cooling plate 71 along the X direction.

[0061] For example, both of the second positioning blocks 4 in each pair are movably arranged along the X direction, as described above regarding the movement of the second positioning blocks 4. During assembly, the side of the liquid cooling plate 71 can be pressed against the third positioning surface of any second positioning block 4, and then the other second positioning block 4 can be adjusted so that the third positioning surfaces of the pair of second positioning blocks 4 clamp the liquid cooling plate 71 along the X direction.

[0062] In one exemplary embodiment of this disclosure, reference is made to Figure 1 As shown, the battery cell assembly fixture also includes a fourth positioning block 63. The fourth positioning block 63 has a fourth positioning surface parallel to the second positioning surface 201, and is located along the Z-direction on the side of the second positioning block 4 away from the base 1. Specifically, during the assembly of the prismatic battery cells, the liquid cooling plate 71 may be placed on the first positioning surface 101 first, and then the battery cell 72 may be installed on the liquid cooling plate 71, i.e., the liquid cooling plate 71 is below and the battery cell 72 is above. Alternatively, the battery cell 72 may be placed on the first positioning surface 101 first, and then the liquid cooling plate 71 may be placed on the battery cell 72, i.e., the battery cell 72 is below and the liquid cooling plate 71 is above. In this exemplary embodiment, the second positioning block 4 and the fourth positioning block 63 can respectively position the liquid cooling plate 71 in the X-direction of the two positions.

[0063] In one exemplary embodiment of this disclosure, the first positioning block 2 is entirely located on one side of the second positioning block 4 along the third direction, that is, the second positioning block 4 is located on the part of the base 1 near the end along the Y direction, referring to... Figure 1 , Figure 2 As shown.

[0064] The first pressing device 3 includes a pressure plate 31, which is movably disposed along the Z-axis to press the battery cell 72 against the liquid cooling plate 71, so that the battery cell 72 is firmly attached to the liquid cooling plate 71. Exemplarily, the pressure plate 31 can move linearly along the Z-axis or swing about the X-axis or Y-axis, thereby contacting or disengaging from the battery cell 72 or the liquid cooling plate 71. For example, the first pressing device 3 may include a fixed support fixedly disposed on the base 1, and the pressure plate 31 and the fixed support can be connected by a linkage mechanism, a gear and rack mechanism, or a lead screw and nut mechanism; or, the pressure plate 31 can be driven by a servo mechanism to achieve movement along the Z-axis.

[0065] In one exemplary embodiment of this disclosure, reference is made to Figure 1 , Figure 5 As shown, the first pressing device 3 includes a first support 32, a hinge mechanism 33, and a pressure plate 31. The first support 32 is fixedly mounted on the base 1, and the two ends of the hinge mechanism 33 are rotatably connected to the first support 32 and the pressure plate 31, respectively, so that the pressure plate 31 is rotatably mounted relative to the first support 32 about the Y direction. When assembled or not assembled, the pressure plate 31 can be lifted, for example, so that the bottom surface of the pressure plate 31 is parallel to the second positioning surface 201, reducing the space occupied.

[0066] Specifically, refer to Figure 5 As shown, one end of the pressure plate 31 is provided with an extension arm 311, and the other end of the extension arm 311 is hinged to the first support 32. The hinge mechanism 33 includes a handle 331 and a rotating arm 332. One end of the rotating arm 332 is hinged to the handle 331, and the other end is hinged to the extension arm 311 at a position between the two ends of the extension arm 311. One end of the handle 331 forms a handle head 333, and the other end of the handle 331 opposite to the handle head 333 is hinged to the first support 32, and the hinge position is different from that of the extension arm 311. By moving the handle head 333, the handle 331 rotates relative to the first support 32 around the Y-axis, which drives the rotating arm 332 to rotate, thereby causing the extension arm 311 to swing, and pressing down the pressure plate 31 at the end of the extension arm 311.

[0067] In one exemplary embodiment of this disclosure, reference is made to Figure 1 As shown, the battery cell assembly fixture also includes a second clamping device 5, which is located at one end of the base 1. All of the first positioning blocks 2 are located on one side of the second clamping device 5 along the Y-direction; that is, the second clamping device 5 is located near the end of the base 1 along the Y-direction. (Reference) Figure 3 The diagram shows a second pressing device 5, which includes a pressing head 51 that is movably disposed along the Z-direction.

[0068] The pressure head 51 can be used to press the liquid cooling pipe 53 onto the water nozzle 73 at the end of the liquid cooling plate 71, see reference. Figure 3 As shown, the second clamping device 5 may include a screw and nut mechanism. The second clamping device 5 includes a second support 54, a pressure rod 55, and a handle 56. The second support 54 is fixedly disposed at one end of the base 1, and the handle 56 is disposed at the end of the pressure rod 55 away from the base 1. By rotating the handle 56, the pressure rod 55 can be driven to move relative to the second support 54 in the Z direction, thereby driving the pressure head 51 to move in the Z direction.

[0069] For example, refer to Figure 3As shown, the end of the pressure head 51 near the first positioning surface 101 is provided with a guide post 52 extending in the first direction. During the pressing process of the pressure head 51 pressing down on the liquid cooling tube 53, the guide post 52 can extend into the liquid cooling tube 53 to guide it. Specifically, the guide post 52 can maintain the axis of the liquid cooling tube 53 during the pressing process, keeping the liquid cooling tube 53 vertical and preventing it from tilting under the pressure of the pressure head 51, which would result in misalignment on the water nozzle 73 at the end of the liquid cooling plate 71.

[0070] In one exemplary embodiment of this disclosure, reference is made to Figure 3 As shown, the battery cell assembly fixture also includes a clamping pad 61, which is stacked on the base 1 along the Z-axis; the orthographic projection of the guide post 52 onto the first positioning surface 101 is within the clamping pad 61. The clamping pad 61 can support the bottom of the water nozzle 73 of the liquid cooling plate 71 when the pressure head 51 presses down on the liquid cooling pipe 53, ensuring that the water nozzle 73 of the liquid cooling plate 71 is not bent or deformed during the pressing process between the water nozzle 73 of the liquid cooling plate 71 and the liquid cooling pipe 53.

[0071] In one exemplary embodiment of this disclosure, reference is made to Figure 3 As shown, the battery cell assembly fixture also includes a third positioning block 62, which is stacked on the base 1 along the Z direction. The third positioning block 62 and the second clamping device 5 are located at opposite ends of all the first positioning blocks 2 along the Y direction.
