Description

Technical Field

[0001] The utility model relates to the technical field of battery modules, in particular to a battery module turning device. Background Art

[0002] With the rapid development of new energy vehicles and energy storage systems, the capacity of battery packs, as core components, has become a focus of industry attention. To increase the capacity of battery packs, in addition to increasing the number of cells in a battery module, multiple battery modules can also be installed in the battery pack.

[0003] Typically, a battery pack consists of two layers of stacked battery modules, with a cold plate sandwiched between them for cooling. The sampling assembly on any battery module is typically located near the bottom of the module. This results in different distances between the sampling assemblies and the cold plate when two battery modules are stacked. This makes the temperature sensor on the assembly susceptible to distance, resulting in reduced temperature detection accuracy.

[0004] To address this issue, the upper battery module must be inverted to ensure that the temperature sensors of both modules are at the same distance from the cold plate, thereby ensuring accurate temperature detection. However, currently, flipping the battery module 180° is typically done manually, which is labor-intensive and results in low production efficiency. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] This embodiment relates to a battery module flipping device that can flip the battery module 301 180 degrees. In terms of overall structure, Figure 1 As shown, this embodiment includes a housing 1 , a turning mechanism 2 and a turning plate 3 .

[0044] The flip mechanism 2 is mounted on the housing 1, and the flip plate 3 is connected to the flip mechanism 2. The flip plate 3 is connected to the rotating end of the flip mechanism 2, and a fixing mechanism for securing the battery module 301 is provided on the end surface of the flip plate 3. The fixing mechanism includes a pressing portion 4 located on the left and right sides of the battery module 301, which can press the battery module 301 against the flip plate 3 and prevent the battery module 301 from separating from the flip plate 3 during the flipping process.

[0045] The pressing force exerted by the pressing plate 404 on the battery module 301 is limited to prevent damage to the battery module 301. Therefore, during the flipping process of the battery module 301, for example, when the battery module 301 is flipped to 90 degrees, the battery module 301 may easily slip on the flip plate 3 due to insufficient friction between the battery module 301 and the flip plate 3, thereby easily causing the battery module 301 to separate from the pressing portion 4, thereby reducing the fixing effect of the battery module 301.

[0046] Therefore, the fixing mechanism also includes clamping portions 5 located on the front and rear sides of the battery module 301, which can constrain the battery module 301 during the flipping process and prevent the battery module 301 from sliding along the end surface of the flip plate 3. When the battery module 301 is fixed to the flip plate 3 by the fixing mechanism, the flip plate 3 is driven to rotate by the flip mechanism 2, causing the battery module 301 to flip 180 degrees.

[0047] As described above, through the arrangement of the flip plate 3 and the flip mechanism 2, the pressing portion 4 and the clamping portion 5 on the flip plate 3 can fix the battery module 301 on the flip plate 3, so that the battery module 301 is flipped 180° as the flip plate 3 is driven to rotate by the flip mechanism 2, thereby achieving the effect of flipping the battery module 301. Compared with the method of manually flipping the battery module 301 in the prior art, the labor intensity of the personnel is reduced and the production efficiency is improved, which is beneficial to the subsequent battery packaging assembly work.

[0048] Based on the above overall introduction, specifically, in this embodiment, when the battery module flipping device of this embodiment is in the initial state, the flip plate 3 is in a horizontal state and the fixing mechanism is located on the top of the flip plate 3, and the battery module 301 to be flipped is moved to the flip plate 3 by the robotic arm.

[0049] To facilitate securing the battery module 301, the pressing unit 4 of this embodiment includes a first linear drive unit 401 disposed on the flip plate 3, a connecting plate 402 driven by the first linear drive unit 401, a lifting unit 403 disposed on the connecting plate 402, and a pressing block driven by the lifting unit 403. The lifting unit 403 is disposed on the side of the connecting plate 402 facing the battery module 301. The first linear drive unit 401 can drive the pressing block to move above one side of the battery module 301, and the lifting unit 403 can drive the pressing block to move and press against the top of the battery module 301. It is understood that after the battery module 301 is placed on the flip plate 3, the first linear drive unit 401 first drives the connecting plate 402 toward the battery module 301, so that the pressing plate 404 is located above the battery module 301. Subsequently, the lifting unit 403 drives the pressing plate 404 toward the battery module 301 and presses it against the top of the battery module 301, thereby pressing and fixing the battery module 301 on the battery module 301. After the flip plate 3 is flipped 180 degrees, the pressing unit 4 is inverted. At this time, the pressing plate 404 can support the battery module 301 in the height direction, preventing the battery module 301 from falling off the flip plate 3.

[0050] Thus, by providing the first linear drive unit 401 and the lifting unit 403, the pressing plate 404 is driven to approach and press the battery module 301, thereby ensuring the fixing effect of the battery module 301 and preventing the battery module 301 from separating from the flip plate 3 during the flipping process. At the same time, the provision of the first linear drive unit 401 enables the pressing plate 404 to adapt to battery modules 301 of different widths, thereby improving the versatility of the battery module flipping device of this embodiment. In specific implementation, the pressing parts 4 of this embodiment are arranged in pairs on both sides of the battery module 301, and in order to ensure the pressing effect of the pressing plate 404 on the battery module 301, the pressing parts 4 of this embodiment are configured as two pairs, one on the left and one on the right sides of the battery module 301, to ensure that the pressing plate 404 fixes each position of the battery module 301, preventing the battery module 301 from separating from the flip plate 3, and further improving the fixing effect of the battery module 301.

[0051] Specifically, to further improve the fixing effect on the battery module 301, the first linear drive unit 401 of this embodiment is a linear module, and the lifting unit 403 is an electric push rod. By providing the linear module and the electric push rod, the pressing unit 4 has good displacement accuracy and driving force, which can ensure the accuracy of the movement of the pressing plate 404 and ensure that the pressing plate 404 has sufficient pressure to press the battery module 301. Of course, the first linear drive unit 401 and the lifting unit 403 of this embodiment can also adopt conventional linear drive mechanisms and lifting mechanisms 6 well known to those skilled in the art, as long as they can drive the movement of the pressing plate 404.

[0052] To facilitate the clamping of the battery module 301, the clamping portion 5 of this embodiment includes a second linear drive portion 501 provided on the flip plate 3, and a baffle 502 provided on the movable end of the second linear drive portion 501. The second linear drive portion 501 can drive the baffle 502 to move and abut one end of the battery module 301. Through the provision of the second linear drive portion 501, the baffle 502 can be effectively driven to abut the end plate of the battery module 301, ensuring the clamping effect on the battery module 301, thereby preventing the battery module 301 from sliding during the flipping process. At the same time, the provision of the second linear drive portion 501 enables the baffle 502 to clamp battery modules 301 of different lengths, further improving the versatility of the battery module flipping device of this embodiment.

[0053] Specifically, the second linear drive unit 501 of this embodiment is an electric slide rail, and the baffle 502 is disposed on the movable end of the electric slide rail. The provision of the electric slide rail can improve the movement accuracy of the baffle 502 and the clamping force on the battery module 301, further ensuring the clamping and fixing effect of the battery module 301. At the same time, in a specific implementation, the clamping unit 5 of this embodiment is configured as two pairs, located at the front and rear ends of the battery module 301, to further improve the clamping effect of the battery module 301.

[0054] In this embodiment, the flip plate 3 equipped with the battery module 301 is relatively heavy. In order to ensure the stability of the rotation of the flip plate 3 during the flipping process, the flip mechanism 2 of this embodiment includes a reduction motor 201 provided on one side of the housing 1, a flip shaft driven by the reduction motor 201, and a controller 202 for controlling the start and stop of the reduction motor 201. The controller 202 is connected to the industrial control equipment outside the flip device of the battery module 301 to ensure the normal operation of the flip device of this embodiment. At the same time, the flip shaft can pass through the housing 1 and connect to the flip plate 3. The reduction motor 201 has a large torque. The reduction motor 201 drives the flip shaft to drive the flip plate 3 to rotate, which can ensure that the flip plate 3 equipped with the battery module 301 rotates at a safe and stable speed, ensuring the stability of the rotation of the flip plate 3 and the safety during the flipping process.

[0055] In specific implementation, the reduction motor 201 of this embodiment is configured as two, and the two reduction motors 201 jointly drive the flip shaft to rotate to further increase the torque of the flip shaft, so that the flip plate 3 can carry a heavier battery module 301 for stable and safe flipping.

[0056] In addition, in order to remove the battery module 301 from the flip plate 3 after the flip is completed, so as to facilitate the subsequent battery pack assembly operation, the battery module flipping device of this embodiment further includes a lifting mechanism 6 and a conveying mechanism 7 provided below the housing 1. Figure 2 、 Figure 3When the battery module 301 is turned over and faces the lifting mechanism 6 , the lifting mechanism 6 can move back and forth in the height direction and place the battery module 301 on the conveying mechanism 7 , and the conveying mechanism 7 can transport the battery module 301 to the outside of the housing 1 .

[0057] Among them, when the battery module 301 is flipped, the lifting mechanism 6 can move upward to lift the battery module 301. At this time, the pressing portion 4 and the clamping portion 5 on the flip plate 3 are separated from the battery module 301. Then the battery module 301 descends with the lifting mechanism 6 and is prevented from being on the conveying mechanism 7, so that the conveying mechanism 7 can convey the battery module 301 to the outside of the shell 1, so as to facilitate the transportation of the flipped battery module 301 to other assembly equipment. Thus, through the setting of the lifting mechanism 6 and the conveying mechanism 7, it is possible to facilitate the removal of the battery module 301 from the flip plate 3 and transport it to the outside of the battery module flipping device to facilitate subsequent battery packaging operations. In specific implementation, the pressing plate 404 for pressing the battery module 301 in this embodiment is pressed against a position close to the side of the battery module 301 to expose most of the area in the center of the battery module 301 for support by the lifting mechanism 6, thereby preventing interference between the pressing portion 4 and the lifting mechanism 6.

[0058] Specifically, the conveying mechanism 7 of this embodiment includes a frame 701 disposed below the housing 1, and a plurality of conveying rollers 702 disposed on the frame 701 and driven by a motor. The provision of the conveying rollers 702 provides a simple and reliable structure, capable of transporting the battery module 301 to the exterior of the battery module flipping device, thereby ensuring the reliability of the conveying mechanism 7.

[0059] Furthermore, in order to facilitate the lifting mechanism 6 to support the battery module 301, as shown in FIG. Figure 2 As shown, the lifting mechanism 6 of this embodiment includes at least one lifting cylinder 601, which is arranged between two adjacent conveying rollers 702. The top of the lifting cylinder 601 is provided with a detachable module tray 602, and the module tray 602 can carry the flipped battery module 301. In addition, it should be noted that Figure 2 The flip plate 3 shown in FIG. 3 flips the battery module 301 over and places the battery module 301 on the module tray 602 , and then flips over again and resets.

[0060] When the lifting cylinder 601 drives the module tray 602 to its lowest point, the module tray 602 carrying the battery module 301 separates from the lifting cylinder 601 and is placed on the conveyor rollers 702 of the conveyor mechanism 7. The installation of the lifting cylinder 601 thus improves the stability of the lifting movement of the battery module 301. The module tray 602 also increases the support area of the lifting mechanism 6 for the battery module 301, thereby improving the stability of the lifting mechanism 6 in supporting the battery module 301. Furthermore, the module tray 602 can carry the battery module 301 and move on the conveyor mechanism 7, preventing the battery module 301 from colliding with the conveyor mechanism 7.

[0061] During specific implementation, in order to improve the lifting stability of the module tray 602 carrying the battery module 301, two lifting cylinders 601 are configured, and the two lifting cylinders 601 are arranged at intervals along the length direction of the battery module 301. The provision of two lifting cylinders 601 increases the support points and bearing capacity of the module tray 602, thereby further improving the support effect of the lifting mechanism 6 on the battery module 301.

[0062] In summary, the flipping mechanism 2 of the battery module 301 of this embodiment, through the setting of the flip plate 3 and the flip mechanism 2, the pressing part 4 and the clamping part 5 on the flip plate 3 can fix the battery module 301 on the flip plate 3, so that the battery module 301 is flipped 180° as the flip plate 3 is driven by the flip mechanism 2 to rotate, thereby achieving the effect of flipping the battery module 301. Compared with the method of manually flipping the battery module 301 in the prior art, the labor intensity of personnel is reduced and the production efficiency is improved, which is beneficial to the subsequent battery packaging assembly work and has good practicality.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
