Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] As described in the background section, existing auxiliary tooling generally uses upper and lower pressure plates to clamp the battery cells, and the upper and lower pressure plates are connected and fixed by bolt and nut assemblies. However, this clamping and fixing method involves cumbersome repeated disassembly and reassembly of bolts and nuts, resulting in a significant reduction in overall assembly efficiency.

[0026] Based on this, please refer to Figures 1-8 This utility model provides a battery cell assembly auxiliary fixture 100, which can effectively improve the aforementioned technical problems, that is, it can improve the assembly efficiency of the battery cell 2011. The battery cell assembly auxiliary fixture 100 will be described in detail below.

[0027] Please refer to Figures 1-3 , Figure 1 This is a schematic diagram of the structure of the cell assembly auxiliary tooling 100 provided in this embodiment. Figure 2 This is a schematic diagram of the structure of the battery module 200 provided in this embodiment. Figure 3 This is a schematic diagram of the first assembly position of the cell assembly auxiliary tooling 100 and the battery module 200 provided in this embodiment.

[0028] Combination Figures 1-3 The battery module 200 includes two battery packs 201 and an intermediate connector 202 disposed between the two battery packs 201. Each battery pack 201 includes multiple battery cells 2011 arranged sequentially. It is easy to understand that the two battery packs 201 can be understood as an upper battery pack 201 and a lower battery pack 201. After applying adhesive to both the upper and lower surfaces of the intermediate connector 202, it is bonded to the upper battery pack 201 and the lower battery pack 201 respectively. To ensure the bonding effect, a cell assembly auxiliary fixture 100 is used to press and fix the upper and lower battery packs 201 together.

[0029] Specifically, the cell assembly auxiliary tooling 100 includes an upper pressing structure 10, a lower pressing structure 20, an upper connector 30, and a lower connector 40. The lower pressing structure 20 abuts against the upper pressing structure 10, and a cell assembly space 50 is formed between the lower pressing structure 20 and the upper pressing structure 10. The upper connector 30 is disposed on the upper pressing structure 10, and the lower connector 40 is disposed on the lower pressing structure 20. The upper connector 30 and the lower connector 40 are used to rotate and lock each other so that the upper pressing structure 10 and the lower pressing structure 20 are connected and fixed.

[0030] In other words, when assembling the battery module 200, the lower battery pack 201 is first placed on the lower pressing structure 20, and then the double-sided adhesive intermediate connector 202 is placed on one side of the lower battery pack 201. Next, the upper battery pack 201 is placed on the intermediate connector 202, so that the upper and lower battery packs 201 are bonded to the intermediate connector 202. At this time, the upper pressing structure 10 is placed on the upper battery pack 201, and the upper connector 30 and the lower connector 40 are connected and fixed by rotating and locking each other, thereby pressing and fixing the upper and lower battery packs 201 and the intermediate connector 202. It is easy to understand that after the glue has cured, when the battery module 200 needs to be removed, simply rotate the upper connector 30 and the lower connector 40 to loosen the upper pressing structure 10 and the lower pressing structure 20. Compared with the existing method of connecting with bolts and nuts, this simplifies the operation process, reduces the workload of workers, and improves the assembly efficiency of the battery cell 2011.

[0031] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the locking process between the upper connector 30 and the lower connector 40 provided in this embodiment, in conjunction with... Figure 1 and Figure 4 The upper connector 30 includes a first fixed base 31 and a first rotating block 32, and the first fixed base 31 is connected to the upper pressing structure 10; the lower connector 40 includes a second fixed base 41 and a second rotating block 42, and the second fixed base 41 is connected to the lower pressing structure 20.

[0032] Further, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the first fixing base 31 and the second fixing base 41 provided in this embodiment. Figure 6 This is a partial structural diagram of the upper connector 30 and the lower connector 40 provided in this embodiment.

[0033] Combination Figure 1 , Figures 4-6 A first fixed base 31 has a first rotating groove 311 on the side near the upper pressing structure 10; a first rotating block 32 is disposed between the first fixed base 31 and the upper pressing structure 10, and the first rotating block 32 is rotatably disposed in the first rotating groove 311. A second fixed base 41 has a second rotating groove 411 on the side near the lower pressing structure 20; a second rotating block 42 is disposed between the second fixed base 41 and the lower pressing structure 20, and the second rotating block 42 is rotatably disposed in the second rotating groove 411. When the upper pressing structure 10 and the lower pressing structure 20 are engaged, the first rotating groove 311 and the second rotating groove 411 can communicate with each other.

[0034] The first rotating block 32 and the second rotating block 42 are respectively used to rotate relative to the first fixed base 31 and the second fixed base 41, so that the first rotating block 32 and the second rotating block 42 are simultaneously located in the first rotating groove 311 and the second rotating groove 411.

[0035] like Figure 4 As shown, it should be noted that when the upper connector 30 and lower connector 40 on the left are not locked and fixed, the positions of the first rotating block 32 and the second rotating block 42, that is, the upper pressing structure 10 and the lower pressing structure 20 are not connected and fixed at this time. The first rotating block 32 is only in the first rotating groove 311, and the second rotating block 42 is only in the second rotating groove 411. However, when the upper connector 30 and lower connector 40 on the right are locked and fixed, the positions of the first rotating block 32 and the second rotating block 42, that is, the upper pressing structure 10 and the lower pressing structure 20 are connected and fixed at this time. The first rotating block 32 is simultaneously in the first rotating groove 311 and the second rotating groove 411, and the second rotating block 42 is also simultaneously in the first rotating groove 311 and the second rotating groove 411.

[0036] In other words, from Figure 4 Moving from the left-hand assembly position to the right-hand assembly position requires rotating both the first rotating block 32 and the second rotating block 42 counterclockwise. This causes a portion of the first rotating block 32 to extend from the first rotating groove 311 into the second rotating groove 411, and a portion of the second rotating block 42 to extend from the second rotating groove 411 into the first rotating groove 311, thus locking and securing the upper connector 30 and the lower connector 40. Of course, when it is necessary to release the locking state and disassemble the upper pressing structure 10 and the lower pressing structure 20, simply rotate the first rotating block 32 and the second rotating block 42 clockwise. This causes the first rotating block 32 to retract from the second rotating groove 411, and the second rotating block 42 to retract from the first rotating groove 311 into the second rotating groove 411. The installation and disassembly operations are convenient, reducing the workload of workers and thus improving the assembly efficiency of the battery cell 2011.

[0037] Combination Figure 4 and Figure 6 To facilitate the operator's rotation of the first rotating block 32, the upper connector 30 also includes a first rotating handle 33, which is connected to the first rotating block 32. Similarly, to facilitate the operator's rotation of the second rotating block 42, the lower connector 40 also includes a second rotating handle 43, which is connected to the second rotating block 42.

[0038] Please refer to Figure 7 , Figure 7 This is an exploded view of the cell assembly auxiliary tooling 100 provided in this embodiment, combined with... Figure 1 and Figure 7In order to improve the clamping strength of the upper pressing structure 10 and the lower pressing structure 20 and enhance the clamping stability of the battery cell 2011, there are multiple upper connectors 30 and multiple lower connectors 40. The multiple upper connectors 30 are spaced apart, and the multiple lower connectors 40 are spaced apart, and they correspond to the multiple upper connectors 30 one by one.

[0039] For example, in this embodiment, there are two upper connectors 30 and two lower connectors 40. The two upper connectors 30 are disposed on opposite side walls of the upper pressing structure 10, and the two lower connectors 40 are disposed on opposite side walls of the lower pressing structure 20. Of course, in other embodiments, the number of upper connectors 30 and lower connectors 40 may be one, three, or four, etc.

[0040] Please continue to combine Figure 7 In order to improve the positioning accuracy of the upper pressing structure 10 and the lower pressing structure 20 and further improve the assembly efficiency, one of the upper pressing structure 10 and the lower pressing structure 20 is provided with a positioning hole 21, and the other of the upper pressing structure 10 and the lower pressing structure 20 is provided with a positioning pin 11, which cooperates with the positioning hole 21.

[0041] It should be noted that in this embodiment, the lower pressing structure 20 is provided with a positioning hole 21, and the upper pressing structure 10 is provided with a positioning pin 11; of course, in other embodiments, the lower pressing structure 20 may be provided with a positioning pin 11, and the upper pressing structure 10 may be provided with a positioning hole 21.

[0042] Furthermore, the upper pressing structure 10 includes a first upper stop block 12, a second upper stop block 13, and an upper pressure plate 14, with the first upper stop block 12 and the second upper stop block 13 spaced apart on the same side of the upper pressure plate 14. The lower pressing structure 20 includes a first lower stop block 22, a second lower stop block 23, and a lower pressure plate 24, with the lower pressure plate 24 spaced apart from the upper pressure plate 14, and the first lower stop block 22 and the second lower stop block 23 spaced apart on the side of the lower pressure plate 24 closest to the upper pressure plate 14.

[0043] The first upper stop 12 abuts against the first lower stop 22, the second upper stop 13 abuts against the second lower stop 23, the first upper stop 12 and the second upper stop 13 are both provided with upper connectors 30, and the first lower stop 22 and the second lower stop 23 are both provided with lower connectors 40; a cell assembly space 50 is formed between the first upper stop 12, the second upper stop 13, the upper pressure plate 14, the first lower stop 22, the second lower stop 23 and the lower pressure plate 24.

[0044] Combination Figure 7Specifically, in this embodiment, an upper connector 30 is provided on the side of the first upper stop 12 away from the second upper stop 13, and an upper connector 30 is also provided on the side of the second upper stop 13 away from the first upper stop 12; correspondingly, a lower connector 40 is provided on the side of the first lower stop 22 away from the second lower stop 23, and a lower connector 40 is also provided on the side of the second lower stop 23 away from the first lower stop 22. Furthermore, a positioning pin 11 is provided on the side of the first upper stop 12 near the first lower stop 22, and on the side of the second upper stop 13 near the second lower stop 23; correspondingly, a positioning hole 21 is provided on the side of the first lower stop 22 near the first upper stop 12, and on the side of the second lower stop 23 near the second upper stop 13. This further improves the connection strength, pressing stability, and positioning accuracy, thereby improving assembly efficiency.

[0045] Combination Figure 1 , Figure 3 and Figure 7 To facilitate the installation of the battery cell 2011 and better press the upper and lower battery packs 201 together, in this embodiment, the upper pressure plate 14 has a plurality of first mounting slots 141 on the side near the lower pressure plate 24. These first mounting slots 141 are located between the first upper stop block 12 and the second upper stop block 13, and are used to install the side portion of the battery cell 2011. The lower pressure plate 24 has a plurality of second mounting slots 241 on the side near the upper pressure plate 14. These second mounting slots 241 are located between the first lower stop block 22 and the second lower stop block 23, and are also used to install the side portion of the battery cell 2011.

[0046] Understandably, multiple first mounting slots 141 are arranged sequentially along the interval direction between the first upper stop block 12 and the second upper stop block 13, and multiple second mounting slots 241 are arranged sequentially along the interval direction between the first lower stop block 22 and the second lower stop block 23.

[0047] Please refer to Figure 8 , Figure 8 This is a schematic diagram of the second assembly position of the cell assembly auxiliary tooling 100 and the battery module 200 provided in this embodiment, combined with... Figure 3 and Figure 8 It should be noted that, Figure 3 The assembly position shown is where the auxiliary tooling 100 for cell assembly presses and fixes the cell 2011 in the battery module 200 to the intermediate connector 202, achieving the assembly position for adhesive bonding. After the adhesive cures, it can be... Figure 3 The battery cell assembly auxiliary fixture 100 is flipped over so that the top of the battery cell 2011 faces upwards, i.e., it is in the correct position. Figure 8The battery module 200 is then assembled at its current position. This subsequent assembly process involves welding the positive and negative electrodes to the nickel plates at the top of the cell 2011.

[0048] Therefore, in order to improve the stability of the welding process between the positive and negative electrodes of the 2011 battery cell and the nickel sheet, please combine... Figure 7 and Figure 8 In this embodiment, the upper pressing structure 10 further includes an upper side plate 15, which is disposed on the side of the upper pressing plate 14 near the lower pressing plate 24 and is simultaneously connected to the first upper stop block 12 and the second upper stop block 13. The upper side plate 15 is used to abut against the bottom of the battery cell 2011. The lower pressing structure 20 further includes a lower side plate 25, which is disposed on the side of the lower pressing plate 24 near the upper pressing plate 14 and is simultaneously connected to the first lower stop block 22 and the second lower stop block 23. The lower side plate 25 is used to abut against the bottom of the battery cell 2011.

[0049] In other words, the upper side plate 15 can abut and fix to the bottom of the cell 2011 in the upper battery pack 201, and the lower side plate 25 can abut and fix to the bottom of the cell 2011 in the lower battery pack 201, thereby improving the installation stability of the battery pack 201 and ensuring the subsequent welding effect. In addition, through the cooperation of the first mounting groove 141 and the second mounting groove 241, the cooperation of the positioning pin 11 and the positioning hole 21, and the cooperation of the upper side plate 15 and the lower side plate 25, the cell 2011 can be limited in multiple dimensions, thereby further improving the accuracy of assembly positioning and reducing the defect rate in the assembly process.

[0050] Please continue to combine Figure 1 and Figure 7 To facilitate operators in handling the upper pressing structure 10 and the lower pressing structure 20, the cell assembly auxiliary tooling 100 also includes an upper handle 61 and a lower handle 62. The upper handle 61 is located on the side of the upper pressing plate 14 away from the lower pressing plate 24, and the lower handle 62 is located on the side of the lower pressing plate 24 away from the upper pressing plate 14.

[0051] It should be noted that there can be multiple upper handles 61 and lower handles 62. For example, in this embodiment, there are two upper handles 61 and two lower handles 62. Of course, in other embodiments, there can be one, three, or four upper handles 61 and lower handles 62, etc.

[0052] Due to the design of the lower handle 62, the lower pressure plate 24 may be unstable during the pressing process of the battery cell 2011. Therefore, in order to ensure the stability of the lower pressing structure 20 during installation, the battery cell assembly auxiliary tooling 100 also includes a pad 70. The pad 70 is located on the side of the lower pressure plate 24 away from the upper pressure plate 14, and the lower end face of the pad 70 protrudes from the lower end face of the lower handle 62.

[0053] It is easy to understand that when the pad 70 is placed on the ground or other assembly platform, the lower end face of the lower handle 62 has a gap with the ground or other assembly platform, which can prevent the lower handle 62 from contacting the ground or other assembly platform, thereby improving the stability during the pressing process.

[0054] It should be noted that the number of spacers 70 can also be multiple to further improve installation stability. For example, in this embodiment, the number of spacers 70 is two; of course, in other embodiments, the number of spacers 70 can also be one, three, or four, etc.

[0055] In summary, the embodiments of this utility model provide a battery cell assembly auxiliary fixture 100, which includes an upper pressing structure 10, a lower pressing structure 20, an upper connector 30, and a lower connector 40. The lower pressing structure 20 abuts against the upper pressing structure 10, and a battery cell assembly space 50 is formed between the lower pressing structure 20 and the upper pressing structure 10. The upper connector 30 is disposed on the upper pressing structure 10, and the lower connector 40 is disposed on the lower pressing structure 20. The upper connector 30 and the lower connector 40 are used to rotate and lock each other so that the upper pressing structure 10 and the lower pressing structure 20 are connected and fixed. When assembling the battery module 200, the lower battery pack 201 is first placed on the lower pressing structure 20. Then, the double-sided adhesive intermediate connector 202 is placed on one side of the lower battery pack 201. Next, the upper battery pack 201 is placed on the intermediate connector 202, so that the upper and lower battery packs 201 are bonded to the intermediate connector 202. At this time, the upper pressing structure 10 is placed on the upper battery pack 201. The upper connector 30 and the lower connector 40 are connected and fixed by rotating and locking each other, thereby pressing and fixing the upper and lower battery packs 201 and the intermediate connector 202. It is easy to understand that after the glue has cured, when the battery module 200 needs to be removed, simply rotate the upper connector 30 and the lower connector 40 to loosen the upper pressing structure 10 and the lower pressing structure 20. Compared with the existing method of connecting with bolts and nuts, this simplifies the operation process, reduces the workload of workers, and improves the assembly efficiency of the battery cell 2011.
