[0002] During battery manufacturing, battery cells need to be installed between upper and lower cover plates to assemble a battery module. The battery cells are usually bonded to the upper and lower cover plates with adhesive. After bonding, the battery cells and the upper and lower cover plates need to be pressed together to ensure the bonding is strong.

[0003] However, some battery modules in the existing technology are relatively long, and the upper and lower cover plates may be arched in the middle section. After the glue solidifies, poor welding may occur during the subsequent welding process of the battery module, affecting the welding quality and requiring rework. This affects the processing quality, increases the battery module production time, and increases production costs. Utility Model Content

[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] In battery manufacturing, battery cells need to be installed between upper and lower cover plates to assemble a battery module. The cells are typically bonded to the cover plates with adhesive, and after bonding, the cells and cover plates need to be pressed together to ensure a strong bond. However, some existing battery modules are quite long, and the cover plates may arch in the middle section. After the adhesive solidifies, poor welding may occur during subsequent welding processes, affecting welding quality and requiring rework. This impacts processing quality, increases battery module manufacturing time, and raises production costs.

[0035] Based on this, please refer to Figure 1 and Figure 2The battery module pressing fixture 1000 provided in the embodiments of this utility model can improve the aforementioned technical problems. This battery module pressing fixture 1000 can ensure that the upper and lower cover plates are completely and tightly bonded to the battery cell, guaranteeing the quality of subsequent processing, thereby shortening processing time and reducing production costs.

[0036] Figure 1 This is a schematic diagram of the battery module pressing fixture 1000 with battery module 2000 provided in an embodiment of the present utility model; Figure 2 This is a schematic diagram of the battery module pressing fixture 1000 provided in an embodiment of this utility model; Figure 3 This is a schematic diagram from a second perspective of the battery module pressing fixture 1000 provided in an embodiment of this utility model.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the battery module pressing fixture 1000 in this embodiment includes a base plate 100, a first baffle 200, a second baffle 300, and a clamping member 400. The first baffle 200 is connected to the base plate 100; the second baffle 300 is rotatably connected to the base plate 100; the second baffle 300 and the first baffle 200 are opposite to each other and spaced apart, forming a clamping space 900. The first baffle 200 and the second baffle 300 are used together to clamp and fix the battery module 2000. One end of the clamping member 400 abuts against the first baffle 200, and the other end of the clamping member 400 bypasses the clamping space 900 and abuts against the second baffle 300 to clamp the first baffle 200 and the second baffle 300. Specifically, the base plate 100 in this embodiment has a rectangular cross-section, and the first baffle 200 and the second baffle 300 are spaced apart along the length of the base plate 100. The first baffle 200 is perpendicularly connected to the base plate 100. Of course, the base plate 100 can also be designed in other shapes, such as a disc, etc., which are not limited here.

[0038] The upper and lower cover plates, already coated with adhesive, are glued to both sides of the battery cell assembly to form a preliminary battery module 2000. The battery module 2000 is then placed between the first baffle 200 and the second baffle 300, with the upper or lower cover plate abutting against the first baffle 200. The second baffle 300 is then rotated to ensure complete contact with the other cover plate of the battery module 2000. The first baffle 200 and the second baffle 300 are then locked in place using clamping devices 400 for a period of time until the adhesive has completely cured. The first baffle 200 and the second baffle 300 ensure complete contact with both cover plates of the battery module 2000, preventing any arching of the cover plates and ensuring a seamless fit between the cover plates and the battery cell assembly, thus guaranteeing the quality of subsequent processing.

[0039] By providing a rotatable second baffle 300, after the battery module 2000 is placed between the first baffle 200 and the second baffle 300, the second baffle 300 can be rotated to ensure complete contact with the upper or lower cover plate of the battery module 2000. A clamping member 400 is provided to hold and fix the first baffle 200 and the second baffle 300 after the battery module 2000 is placed in, maintaining this position for a period of time until the adhesive cures before releasing the clamping member 400. This improves the bonding strength between the upper and lower cover plates and the battery cells in the battery module 2000. This design of the clamping member 400 simplifies the structure and facilitates operation. Through the above design, the upper and lower cover plates of the battery module 2000 can be completely and tightly bonded to the battery cells, thereby improving the quality of subsequent processing, shortening processing time, and reducing production costs.

[0040] Please see Figure 1 In this embodiment, the battery module pressing fixture 1000 can press together multi-layer battery cell groups. To prevent scratching between the multi-layer battery cell groups, an epoxy board is provided between adjacent battery cell groups. Specifically, in this embodiment, the battery module pressing fixture 1000 is used to press together the frosted battery module 2000.

[0041] To ensure the stability of the second baffle 300 rotation, please refer to [link / reference needed]. Figure 2 and Figure 3 The battery module pressing fixture 1000 in this embodiment further includes a first fixing seat 500 and a second fixing seat 600 mounted on the base plate 100. The first fixing seat 500 and the second fixing seat 600 are spaced apart along a direction perpendicular to the spacing between the first baffle 200 and the second baffle 300. The second baffle 300 is rotatably connected to both the first fixing seat 500 and the second fixing seat 600. In this embodiment, the first fixing seat 500 and the second fixing seat 600 are spaced apart along the length of the base plate 100. Specifically, in this embodiment, the first fixing seat 500 is rotatably connected to the second baffle 300 via a first rotating shaft pin 710; and / or, the second fixing seat 600 is rotatably connected to the second baffle 300 via a second rotating shaft pin 720. In this embodiment, the rotation axes of the first rotating shaft pin 710 and the second rotating shaft pin 720 are collinear. Of course, the rotation axes of the two rotating shaft pins may not be collinear, as long as they are arranged parallel. Besides using a rotating pin connection, a through hole can be provided in the second baffle 300, with a rotating shaft installed inside the through hole. Both the first fixed seat 500 and the second fixed seat 600 are rotatably connected to the rotating shaft. Alternatively, the second baffle 300 can also be rotatably connected to the first fixed seat 500 and the second fixed seat 600 using other rotating connection structures, which are not limited here. Furthermore, the second baffle 300 can also be directly rotatably connected to the base plate 100.

[0042] To position the battery module 2000 correctly and ensure it is fully aligned with the first baffle 200 and the second baffle 300, please refer to the following documentation. Figure 2 and Figure 3 In this embodiment, the first fixing seat 500 is elongated and is used to support one end of the battery module 2000. Specifically, the first fixing seat 500 extends along the width of the base plate 100 and supports the end adjacent to the upper and lower cover plates of the battery module 2000, ensuring that the battery module 2000 is completely positioned between the first baffle 200 and the second baffle 300. In this embodiment, the first fixing seat 500 is rectangular. However, the shape of the first fixing seat 500 can also be designed as a semi-cylindrical, cylindrical, or other shapes, as long as it extends along the width of the base plate 100 and supports one end of the battery module 2000 for positioning and fixing the battery module 2000. The shape of the first fixing seat 500 is not limited here.

[0043] In addition, please see Figure 2 and Figure 3 In this embodiment, along the interval direction between the first baffle 200 and the second baffle 300, that is, along the width direction of the base plate 100, a sloping surface 110 is formed on one side of the base plate 100, extending at an acute angle relative to the reference plane of the base plate 100. The thickness of the sloping surface 110 gradually decreases from the connection point with the base plate 100 to the edge of the base plate 100. That is, a downwardly sloping surface 110 is provided on one side of the base plate 100 to facilitate the battery module 2000 being pushed between the first baffle 200 and the second baffle 300 via this sloping surface 110. In this embodiment, the sloping surface 110 is located on the side of the base plate 100 away from the first fixing seat 500. The second fixing seat 600 is not located between the first baffle 200 and the second baffle 300 to facilitate the installation of the battery module 2000.

[0044] To improve the structural strength of the second baffle 300 and thus the overall structural strength of the battery module pressing fixture 1000, the battery module pressing fixture 1000 in this embodiment further includes reinforcing ribs 800, which are disposed on the side of the first baffle 200 away from the second baffle 300. There are multiple reinforcing ribs 800, which are spaced apart.

[0045] To further enhance the connection strength between the base plate 100 and the first baffle 200, the reinforcing rib 800 in this embodiment has a trapezoidal cross-sectional shape, and the reinforcing rib 800 connects both the base plate 100 and the first baffle 200. Of course, the cross-section of the reinforcing rib 800 can also be designed as a triangle or other shapes, and the reinforcing rib 800 can also be designed as other structural shapes, which are not limited here.

[0046] Please see Figure 2 and Figure 3 and combined Figure 1In this embodiment, the clamping member 400 is an F-clamp. The F-clamp includes a duckbill bar and a movable jaw that is sleeved on the duckbill bar and can slide along the duckbill bar. By rotating, the position of the movable jaw on the duckbill bar can be changed to adjust the clamping distance of the F-clamp. The F-clamp is easy to operate and safe and reliable. Moreover, in order to ensure that the first baffle 200 and the second baffle 300 tightly press the battery module 2000 at both ends, the number of clamping members 400 in this embodiment is multiple. The multiple clamping members 400 are parallel and spaced apart along the spacing direction of the first baffle 200 and the second baffle 300. Specifically, the number of clamping members 400 in this embodiment is three. Of course, the number of clamping members 400 can also be one, two, four, etc., depending on the actual use, and is not limited here. In addition, other clamping structures can be used besides the F-clamp, and are not limited here. A movable module is provided on both the side of the second baffle 300 away from the first baffle 200 and the side of the first baffle 200 away from the second baffle 300. The movable module includes a drive component, a moving rod, and a pressure block. The pressure block is connected to the end of the moving rod. The drive component is connected to the moving rod and is used to move the moving rod so that the pressure block abuts against the first baffle 200 or the second baffle 300, thereby pressing the battery module 2000 between the first baffle 200 and the second baffle 300. The drive component and the moving rod can be ball screw structures, or other linear motion mechanisms; no limitation is made here.

[0047] According to the battery module pressing fixture 1000 provided in this embodiment, the working principle of the battery module pressing fixture 1000 is as follows:

[0048] Place the battery module 2000 between the first baffle 200 and the second baffle 300, with the upper or lower cover of the battery module 2000 abutting against the first baffle 200. Then rotate the second baffle 300 so that it is fully attached to the other cover of the battery module 2000. Then use the clamping member 400 to lock the first baffle 200 and the second baffle 300, and keep it for a period of time until the glue is completely cured.

[0049] In summary, the battery module pressing fixture 1000 includes a base plate 100, a first baffle 200, a second baffle 300, and a clamping member 400. The first baffle 200 is connected to the base plate 100; the second baffle 300 is rotatably connected to the base plate 100; the second baffle 300 and the first baffle 200 are opposite to and spaced apart, forming a clamping space 900. The first baffle 200 and the second baffle 300 are used together to clamp and fix the battery module 2000. One end of the clamping member 400 abuts against the first baffle 200, and the other end of the clamping member 400 bypasses the clamping space 900 and abuts against the second baffle 300. The clamping member 400 is used to clamp the first baffle 200 and the second baffle 300. By providing a rotatable second baffle 300, after the battery module 2000 is placed between the first baffle 200 and the second baffle 300, the second baffle 300 can be rotated to ensure complete contact with the upper or lower cover plate of the battery module 2000. A clamping member 400 is provided to hold and fix the first baffle 200 and the second baffle 300 after the battery module 2000 is placed in, maintaining this position for a period of time until the adhesive cures before releasing the clamping member 400. This improves the bonding strength between the upper and lower cover plates and the battery cells in the battery module 2000. This design of the clamping member 400 simplifies the structure and facilitates operation. Through the above design, the upper and lower cover plates of the battery module 2000 can be completely and tightly bonded to the battery cells, thereby improving the quality of subsequent processing, shortening processing time, and reducing production costs.

[0050] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
