Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a pre-pressing device for a double battery pack. Background Art

[0002] In electric vehicles, energy storage systems and other applications that require high energy density battery packs, the performance and quality of the battery pack are directly related to the stability and reliability of the entire system. In the production process of battery packs, pre-pressing is a crucial link. Pre-pressing not only helps to improve the compactness of the internal structure of the battery pack, but also enhances the connection strength between battery cells, thereby improving the overall performance and safety of the battery pack.

[0003] However, traditional battery pack pre-pressing equipment has many limitations and cannot meet the requirements of modern battery pack production for high efficiency, high precision and stability. For example, traditional equipment often adopts a single-station operation mode, that is, only one battery pack can be pre-pressed at a time. This processing method is not only time-consuming, but also limits the overall production capacity of the production line. In addition, most traditional equipment adopts a single-direction pressing method, which makes it difficult to achieve uniform and accurate pressing of all parts of the battery pack. Utility Model Content

[0004] The purpose of the utility model is to provide a pre-pressing device for a dual battery pack, which adopts a symmetrically arranged transfer assembly to realize the simultaneous pre-pressing of two battery packs, thereby greatly improving the production efficiency. At the same time, through the synergistic effect of the first pressing assembly and the second pressing assembly, as well as the setting of the positioning reference plate, it is ensured that the battery pack obtains a uniform and accurate pressing effect during the pre-pressing process.

[0005] A pre-pressing device for a dual battery pack, characterized in that it includes a transfer component, a first clamping component, a second clamping component and a positioning reference plate, the second clamping component and the positioning reference plate are arranged relative to each other, the transfer component is arranged symmetrically, the transfer component includes a first supporting plate, a placement component and a transfer drive component, the placement component is used to place the battery pack to be compressed, the placement component and the first clamping component are arranged on the first supporting plate, the transfer drive component drives the first supporting plate to move horizontally so that the two battery packs to be compressed are close to each other and move between the second clamping component and the positioning reference plate, the first clamping component compresses the battery pack along a first direction, and the second clamping component compresses the battery pack along a second direction, the first direction is perpendicular to the second direction.

[0006] In the above technical solution, two symmetrically arranged transfer assemblies are provided, and the transfer assemblies include a first carrier plate, a placement assembly and a transfer drive. The placement assembly is used to place the battery pack to be pre-pressed, and the transfer drive drives the first carrier plate to move horizontally, so that the two battery packs to be pressed gradually approach and reach between the second clamping assembly and the positioning reference plate, in preparation for the subsequent pressing operation. The symmetrically designed transfer assembly not only ensures the balance of the operation, but also facilitates the simultaneous processing of two battery packs, thereby improving work efficiency. After the two battery packs to be pressed approach each other, the first clamping assembly and the second clamping assembly work together to apply necessary pressure to the battery pack to achieve the purpose of pre-pressing. The first clamping assembly is responsible for compressing the battery pack along the first direction (parallel to the direction of movement of the first carrier plate), ensuring that the battery pack can be uniformly stressed during the pre-pressing process, and avoiding performance problems caused by uneven stress. The second clamping assembly cooperates with the first clamping assembly to apply pressure to the battery pack from the other side, ensuring that the battery pack obtains a comprehensive and balanced compression effect during the pre-pressing process. The positioning reference plate serves as a fixed reference point during the pre-pressing process of the battery pack, which helps to ensure the position accuracy and stability of the battery pack during the pre-pressing process. At the same time, it may also provide a certain support for the battery pack to prevent displacement or deformation during the pressing process. The utility model realizes the pre-pressing of the dual battery pack and ensures that the dual battery pack obtains a uniform and accurate pressing effect during the pre-pressing process.

[0007] Furthermore, it also includes a positioning rod, which is arranged between the second clamping assembly and the positioning reference plate.

[0008] In the above technical solution, a positioning rod is arranged between the second clamping assembly and the positioning reference plate, which further improves the positioning accuracy of the battery pack during the pre-pressing process. The positioning rod serves as a physical reference point, which helps to ensure that the transfer drive moves the battery pack to the correct position, prevents deviation or tilt during the pre-pressing process, and thus improves the pre-pressing quality.

[0009] Furthermore, the placement assembly includes a placement plate and a driving member, and the driving member drives the placement plate to move along the second direction.

[0010] In the above technical solution, by designing a placement assembly including a placement plate and a driving member, and enabling the driving member to drive the placement plate to move along the second direction, the position of the placement plate can be accurately adjusted, which helps to accurately place the battery pack in the pre-pressing area and ensure the smooth progress of the pre-pressing process. At the same time, high-precision positioning also helps to improve the consistency and stability of the pre-pressing effect.

[0011] Furthermore, the first clamping assembly includes a first clamping plate and a first clamping driving member, and the first clamping driving member drives the first clamping plate to move along the first direction.

[0012] In the above technical solution, the design of the first clamping plate and the first clamping drive ensures that the battery pack can be effectively clamped along the first direction, which helps to eliminate gaps inside the battery pack, improve the overall tightness and stability, and provide a better foundation for subsequent assembly or testing processes.

[0013] Furthermore, a reinforcing plate is provided on a side of the first pressing plate facing away from the battery pack.

[0014] In the above technical solution, a reinforcing plate is added to the side of the first clamping plate away from the battery pack, which improves the rigidity and stability of the first clamping plate, helps prevent deformation or damage caused by excessive force during the pre-pressing process, and ensures the smooth progress of the pre-pressing process and the reliability of the pre-pressing effect.

[0015] Furthermore, the second clamping assembly includes a second clamping plate, a second supporting plate and a second clamping driving member, wherein the second clamping driving member is disposed on the second supporting plate, and the second clamping driving member drives the second clamping plate to move along the second direction.

[0016] In the above technical solution, the design of the second pressing plate, the second supporting plate and the second pressing driving member ensures that the battery pack can be effectively pressed along the second direction.

[0017] Furthermore, a pressure sensor is provided at the connection between the second pressing drive member and the second pressing plate.

[0018] In the above technical solution, the setting of the pressure sensor enables the operator to understand the pressure conditions during the pre-pressing process in real time and make adjustments as needed, which helps to avoid battery pack damage due to excessive pre-pressing or performance problems caused by insufficient pre-pressing, and improves the safety and reliability of the pre-pressing process.

[0019] Furthermore, the second clamping assembly also includes a stroke monitor, and the stroke monitor is arranged on a side of the second supporting plate close to the second clamping driving member.

[0020] In the above technical solution, a stroke monitor is added on the side of the second carrier plate close to the second clamping drive member, which can monitor the movement stroke of the second clamping plate in real time, which helps to ensure that the pre-pressing process is carried out within a predetermined range and prevents damage to the equipment or battery pack due to excessive stroke. At the same time, the stroke monitor can also provide important reference data for equipment maintenance.

[0037] The following will further describe the pre-pressing device of the dual battery pack of the utility model in detail with reference to specific embodiments and drawings. The drawings show preferred embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0038] Please refer to Figures 1 to 5 In a preferred embodiment, the pre-pressing device of the dual battery pack of the utility model comprises a transfer component 1, a first clamping component 2, a second clamping component 3 and a positioning reference plate 4, the second clamping component 3 and the positioning reference plate 4 are arranged relatively to each other, the transfer component 1 is arranged symmetrically, the transfer component 1 comprises a first carrier plate 101, a placement component 102 and a transfer drive 103, the placement component 102 is used to place the battery pack 5 to be compressed, the placement component 102 and the first clamping component 2 are arranged on the first carrier plate 101, the transfer drive 103 drives the first carrier plate 101 to move horizontally, so that the two battery packs 5 to be compressed are close to each other and move to between the second clamping component 3 and the positioning reference plate 4, the first clamping component 2 compresses the battery pack 5 along the first direction, and the second clamping component 3 compresses the battery pack 5 along the second direction, and the first direction is perpendicular to the second direction.

[0039] It can be seen from the above technical solution that there are two symmetrically arranged transfer assemblies 1, the transfer assemblies 1 include a first carrier plate 101, a placement assembly 102 and a transfer driver 103, the placement assembly 102 is used to place the battery pack 5 to be pre-pressed, and the transfer driver 103 drives the first carrier plate 101 to move horizontally, so that the two battery packs 5 to be pressed gradually approach and reach between the second clamping assembly 3 and the positioning reference plate 4, in preparation for the subsequent pressing operation, the symmetrically designed transfer assembly 1 not only ensures the balance of the operation, but also facilitates the simultaneous processing of two battery packs 5, thereby improving work efficiency. After the two battery packs 5 to be pressed are close to each other, the necessary pressure is applied to the battery pack 5 through the synergistic effect of the first clamping assembly 2 and the second clamping assembly 3 to achieve the purpose of pre-pressing. The first clamping assembly 2 is responsible for compressing the battery pack 5 along the first direction (parallel to the direction of movement of the first carrier plate 101), ensuring that the battery pack 5 can be evenly stressed during the pre-pressing process, avoiding performance problems caused by uneven stress. The second clamping assembly 3 cooperates with the first clamping assembly 2 to apply pressure to the battery pack 5 from the other side to ensure that the battery pack 5 obtains a comprehensive and balanced clamping effect during the pre-pressing process. The positioning reference plate 4 serves as a fixed reference point during the pre-pressing process of the battery pack 5, which helps to ensure the position accuracy and stability of the battery pack 5 during the pre-pressing process. At the same time, it may also provide a certain support for the battery pack 5 to prevent displacement or deformation during the pressing process. The above scheme realizes efficient and stable pre-pressing of the two battery packs 5. The symmetrical setting and relative movement function of the transfer assembly 1 facilitate the positioning and approach of the battery pack 5; the synergistic effect of the first clamping assembly 2 and the second clamping assembly 3 ensures that the battery pack 5 obtains a comprehensive and balanced clamping effect during the pre-pressing process; and the positioning reference plate 4 further improves the accuracy and stability of the pre-pressing. The utility model not only improves the work efficiency, but also ensures the pre-pressing quality of the battery pack 5, laying a solid foundation for subsequent applications.

[0040] It should be noted that, in this embodiment, the battery pack 5 includes a first end plate 501, a second end plate 502, a third end plate 503, a fourth end plate 504 and a fifth end plate 505. When in use, the first end plate 501 is first connected to the second end plate 502 (the first end plate 501 and the second end plate 502 are perpendicular to each other), and then the first end plate 501 is installed with the positioning reference plate 4. Subsequently, two battery packs 5 to be pre-pressed are placed on the placement plate 1021, and the transfer drive 103 drives the first carrier plate 101 to move, so that the battery pack 5 placed on the placement plate 1021 is abutted against the second end plate 502. After ensuring that the battery pack 5 is in contact with the second end plate 502, manually lock the third end plate 503, the fourth end plate 504 and the fifth end plate 505 to the battery pack, then control the first clamping assembly 2 to press the battery pack 5, and finally control the second clamping assembly 3 to press the battery pack 5, so that the battery pack 5 can receive uniform clamping force to ensure the pre-compression quality.

[0041] Please refer to Figure 1 , this embodiment also includes a positioning rod 6, and the positioning rod 6 is arranged between the second clamping assembly 3 and the positioning reference plate 4. The positioning rod 6 is arranged between the second clamping assembly 3 and the positioning reference plate 4, which further improves the positioning accuracy of the battery pack 5 during the pre-pressing process. The positioning rod 6 serves as a physical reference point, which helps to ensure that the transfer driver 103 moves the battery pack 5 to the correct position, prevents deviation or tilt during the pre-pressing process, and thus improves the pre-pressing quality. When in use, the transfer driver 103 can drive the first carrier plate 101 to the correct position according to the positioning rod 6, so that the battery pack 5 reaches the correct pre-pressing position, preparing for the subsequent clamping operation.

[0042] Please refer to Figure 2 , the placement assembly 102 includes a placement plate 1021 and a driving member 1022, and the driving member 1022 drives the placement plate 1021 to move along the second direction. By designing the placement assembly 102 including the placement plate 1021 and the driving member 1022, and enabling the driving member 1022 to drive the placement plate 1021 to move along the second direction, it is possible to achieve precise adjustment of the position of the placement plate 1021, which helps to accurately place the battery pack 5 in the pre-pressing area and ensure the smooth progress of the pre-pressing process. At the same time, high-precision positioning also helps to improve the consistency and stability of the pre-pressing effect. Since the placement plate 1021 can be quickly and accurately moved to the predetermined position, the time required for the battery pack 5 to be placed from pre-pressing to completion can be shortened, which helps to improve the efficiency of the entire pre-pressing process and reduce production costs.

[0043] Please refer to Figure 1 , the first clamping assembly 2 includes a first clamping plate 201 and a first clamping driver 202, and the first clamping driver 202 drives the first clamping plate 201 to move along the first direction. The design of the first clamping plate 201 and the first clamping driver 202 ensures that the battery pack 5 can be effectively clamped along the first direction, which helps to eliminate the gap inside the battery pack 5, improve the overall tightness and stability, and provide a better foundation for the subsequent assembly or testing process. By accurately controlling the output of the first clamping driver 202, it is possible to accurately control the moving speed and clamping force of the first clamping plate 201, which helps to avoid the problem of battery pack damage caused by excessive clamping force or poor pre-pressing effect caused by insufficient clamping force. At the same time, the automated operation of the first clamping assembly 2 reduces the need for manual intervention, making the pre-pressing process more efficient. Since the clamping force can be precisely controlled, the pre-pressing time can be shortened as much as possible while ensuring the pre-pressing effect, thereby improving production efficiency.

[0044] At the same time, a reinforcing plate 2011 is provided on the side of the first clamping plate 201 facing away from the battery pack 5. The reinforcing plate 201, as a supporting structure of the first clamping plate 201, can effectively enhance the overall rigidity and structural strength of the first clamping plate 201. During the pre-pressing process, the battery pack 5 will exert a large reaction force on the first clamping plate 201. The design of the reinforcing plate 201 can prevent the first clamping plate 201 from being deformed or damaged due to excessive force, thereby ensuring the smooth progress of the pre-pressing process. During the pre-pressing process, if the first clamping plate 201 is damaged or broken due to insufficient strength, it may cause damage to the operator and equipment. The design of the reinforcing plate 201 greatly reduces this risk and improves the safety of the pre-pressing process.

[0045] Please refer to Figure 5 The second clamping assembly 3 includes a second clamping plate 301, a second carrier plate 302 and a second clamping driver 303. The second clamping driver 303 is arranged on the second carrier plate 302, and the second clamping driver 303 drives the second clamping plate 301 to move along the second direction. Unlike the first clamping assembly 2 which clamps the battery pack 5 along the first direction, the second clamping assembly 3 can clamp the battery pack 5 along the second direction. This multi-dimensional clamping capability ensures that the battery pack 5 is subjected to all-round and uniform pressure during the pre-pressing process, thereby improving the consistency and stability of the pre-pressing effect. Through the clamping action of the second clamping assembly 3, the gap and looseness inside the battery pack can be further eliminated, thereby improving the overall tightness and stability of the battery pack. Similar to the first clamping assembly 2, the second clamping driver 303 in the second clamping assembly 3 can also accurately control the clamping force. By adjusting the output of the second clamping driver 303, the moving speed and clamping force of the second clamping plate 301 can be accurately controlled, thereby meeting the needs of different battery packs 5 or different pre-pressing requirements.

[0046] At the same time, a pressure sensor 304 is provided at the connection between the second clamping drive 303 and the second clamping plate 301. The pressure sensor 304 can monitor the clamping force applied by the second clamping plate 301 to the battery pack 5 in real time, and feed this information back to the control system, so that the operator or the system can promptly understand the magnitude of the clamping force to ensure that it is within a preset range. According to the feedback from the pressure sensor 304, the control system can adjust the output of the second clamping drive 303 in real time to ensure that the clamping force remains in an optimal state, which helps to avoid the problem of damage to the battery pack 5 due to excessive clamping force or poor pre-pressing effect due to insufficient clamping force. In some cases, if the clamping force exceeds the preset safety range, the pressure sensor 304 can trigger the overload protection mechanism and automatically stop the output of the second clamping drive 303 to protect the device and the battery pack 5 from damage.

[0047] Furthermore, in this embodiment, the second clamping assembly 3 further includes a travel monitor 305, which is disposed on the side of the second carrier plate 302 close to the second clamping driver 303. The travel monitor 305 is provided on the side of the second carrier plate 302 close to the second clamping driver 303, so as to monitor the movement travel of the second clamping plate 301 in real time, which helps to ensure that the pre-pressing process is carried out within a predetermined range, and prevents damage to the device or the battery pack 5 due to over-limit travel. At the same time, the travel monitor 305 can also provide important reference data for the maintenance and care of the device.
