Description

Technical Field

[0001] This application relates to the field of assembly technology, and more particularly to an assembly device. Background Technology

[0002] With the increasing severity of environmental pollution and the gradual depletion of traditional energy sources, the comprehensive development of new energy technologies is receiving more and more attention. In the field of electrochemical energy storage, battery packs are being used more and more widely.

[0003] In related technologies, the battery pack assembly method involves assembling the battery box and then placing the batteries into the box in groups. That is, the box is assembled first, and then the battery pack is assembled. Therefore, the battery pack assembly process is relatively complex, inefficient, and difficult to automate. Furthermore, the transfer process between the box and the batteries can also introduce a series of unstable factors, leading to a decrease in yield. Utility Model Content

[0004] This application provides an assembly device that improves assembly efficiency, thereby at least partially solving the above-mentioned technical problems.

[0005] To achieve the above objectives, an assembly apparatus is provided for assembling a battery pack, the battery pack including a housing and battery cells, the assembly apparatus comprising:

[0006] A substrate, wherein the substrate is provided with a support position for supporting the battery cell and the housing; and,

[0007] At least two first clamping members are disposed opposite each other along a first direction and located on opposite sides of the bearing position for clamping the battery cell carried on the bearing position along the first direction.

[0008] Optionally, the bearing position includes a first bearing position and a second bearing position. The first bearing position is used to bear the battery cell, and the second bearing position is used to bear the housing. The second bearing position has an opening, and at least one of the first clamping members passes through the opening to clamp the battery cell along a first direction.

[0009] By providing an opening in the second bearing position, the first clamping member can pass through the opening and utilize the remaining space inside the battery pack to clamp and compress the battery cells inside the casing without affecting the installation of the side beams and expansion beams, thus making it easier to install the casing in the battery pack.

[0010] Optionally, the assembly equipment further includes a limiting rod that extends along the first direction, and the first clamping members are all slidably mounted on the limiting rod.

[0011] Based on this, the limiting rod can provide precise guidance and stable support for the movement of the first clamping member. Since the limiting rod extends along the first direction, it can ensure that the first clamping member slidably mounted on the limiting rod moves along the first direction, thereby preventing the first clamping member from deflecting, tilting or other abnormal situations during compression. This ensures that the pressure on both sides of the cell is accurately applied to the cell, reduces the probability of cell damage due to uneven force, and improves the consistency of battery pack assembly.

[0012] Optionally, the limiting rod is disposed on the side of the substrate opposite to the battery cell.

[0013] This ensures a clean and flat substrate surface, prevents the limiting rod from negatively impacting the installation of the battery cells and casing, and also allows users to observe the movement of the first clamp and the installation of the battery cells and casing during battery pack installation, thus improving the safety of the battery pack installation process.

[0014] Optionally, the assembly equipment further includes at least two second clamping members, which are arranged opposite each other along a second direction, so that the battery cell can be installed between the at least two first clamping members, so that the at least two second clamping members can clamp the battery cell along the second direction; the first direction and the second direction intersect.

[0015] By setting a second clamping member arranged opposite to the first clamping member along a second direction intersecting the first direction, the second clamping member and the first clamping member can cooperate with each other to clamp and compress multiple sides of the battery cell, so that the size of the battery cell module composed of multiple battery cells meets the requirements, and avoids the problem of local stress concentration or assembly failure of the battery cell due to unidirectional compression of the battery cell.

[0016] Optionally, the bearing position is provided with a limiting groove, which is used to install the terminal post of the battery cell.

[0017] Based on this, the battery cell is mounted with the side containing the terminals facing the substrate, that is, it is placed upside down on the substrate. This facilitates the installation of the battery cell and allows the bottom plate in the casing to be installed on the bottom surface of the battery cell without affecting the installation of the battery cell.

[0018] Optionally, there are at least two limiting grooves, and the at least two limiting grooves are spaced apart along the first direction, so that the two terminals of the battery cell are respectively installed in the two adjacent limiting grooves.

[0019] Based on this, both terminals of the battery cell have stable installation positions, making the battery cell installation more secure and reducing the probability of the battery cell shaking during the clamping process of the first or second clamping component, thus preventing damage to the battery cell.

[0020] Optionally, the width of the limiting groove is greater than or equal to 5 mm and less than or equal to 80 mm.

[0021] By controlling the width of the limiting groove within a suitable range, the probability of collision between the terminal post and the groove wall is reduced while ensuring the limiting effect on the terminal post, thereby improving the stability of cell installation.

[0022] Optionally, the battery pack further includes a liquid cooling plate disposed between the battery cells and / or between the battery cells and the housing. The assembly equipment further includes a first limiting member, which is provided between at least two adjacent limiting grooves. The first limiting member is used to limit the liquid cooling plate.

[0023] By setting a first limiting component to limit the liquid cooling plate, the position of the liquid cooling plate on the side of the battery cell is restricted, ensuring that the liquid cooling plate is aligned with the corresponding area of ​​the battery cell, thereby improving the cooling effect of the liquid cooling plate on the battery cell.

[0024] Optionally, the first limiting member protrudes from the end of the substrate.

[0025] Based on this, the first limiting member provides a stable positioning reference for the installation of the liquid cooling plate. The protruding first limiting member can block and limit one or more sides of the liquid cooling plate, thereby accurately constraining the position of the liquid cooling plate and effectively preventing the liquid cooling plate from sliding or shifting.

[0026] Optionally, the assembly equipment further includes a second limiting member, which is provided between at least two adjacent limiting grooves, and the second limiting member extends along a first direction on the substrate to support the liquid cooling plate.

[0027] To enable the liquid cooling plate to cool the central area of ​​the battery cell, a second limiting component is provided to raise the liquid cooling plate so that it covers the central area of ​​the battery cell, thereby improving the cooling effect of the liquid cooling plate.

[0028] Optionally, the first limiting member and the second limiting member are spaced apart, and an accommodating space is formed between the first limiting member and the second limiting member to accommodate at least a portion of the liquid cooling plate.

[0029] By providing a accommodating space, uneven areas of the liquid cooling plate can be placed within it, thereby improving the stability of the liquid cooling plate installation.

[0030] Optionally, the assembly equipment further includes a third limiting member, which is provided between at least two adjacent limiting slots to limit the battery cell in the first direction.

[0031] By setting a third limiting component to provide positioning and lateral support for the battery cell, the stability of the battery cell when placed on the substrate is ensured, the probability of the battery cell tipping over is reduced, and the battery cell is then easily clamped by the first clamping component.

[0032] In the assembly equipment of this application embodiment, by integrating the assembly process of the battery cell and the assembly step of the casing, the battery cell insertion operation is eliminated, which improves the assembly efficiency, greatly reduces the precision requirements of the casing, and reduces the probability of damage during the battery cell insertion operation. This can improve the production yield of the battery pack, and at the same time, the battery cell is less likely to be bumped by the casing, which improves the stability of the battery pack.

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0052] This application provides an assembly device 1, please refer to... Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the assembly equipment 1 provided in an embodiment of this application.

[0053] An assembly device 1 is used to assemble a battery pack 2, the battery pack 2 including a housing 21 and battery cells. The assembly device 1 includes a substrate 11 and at least two first clamping members 12. The substrate 11 is provided with a bearing position 111 for bearing the battery cells and the housing 21. The at least two first clamping members 12 are arranged opposite each other along a first direction H1 and located on opposite sides of the bearing position 111 for clamping the battery cells supported on the bearing position 111 along the first direction H1.

[0054] The substrate 11 serves as a support structure, providing a stable and flat assembly platform. The support positions 111 on the substrate 11 are used for precise positioning and placement of the housing 21 of the battery pack 2 and the battery cells to be installed. The first clamping member 12 is used to clamp the battery cells, ensuring that multiple battery cells or battery cells are firmly attached to the housing 21, thus ensuring that the assembled battery pack 2 has a small volume.

[0055] For example, the specific working process of this utility model embodiment is as follows:

[0056] First, the battery cell is placed on the substrate 11. Then, a portion of the housing 21 is placed between the first clamping member 12 and the battery cell. The first clamping member 12 clamps the battery cell and the portion of the housing 21 tightly together. Then, the remaining portion of the housing 21 is installed to form a complete battery pack 2. The first clamping member 12 also serves to compress the battery cell, ensuring that multiple cells are tightly fitted together to achieve the required dimensions and guarantee the consistency of the manufactured battery pack 2.

[0057] This embodiment of the utility model integrates the assembly process of the battery cell with the assembly steps of the casing, eliminating the need to complete the battery cell placement operation. This improves assembly efficiency while significantly reducing the precision requirements of the casing 21 and lowering the probability of damage during battery cell placement. This can improve the production yield of the battery pack 2. At the same time, the battery cell is less likely to be bumped or knocked against the casing 21, thus improving the stability of the battery pack 2.

[0058] In some embodiments, refer to Figures 1 to 5 The bearing position 111 includes a first bearing position 1111 and a second bearing position 1112. The first bearing position 1111 is used to support the battery cell, and the second bearing position 1112 is used to support the housing 21. The second bearing position 1112 is provided with an opening 1113, and at least one first clamping member 12 passes through the opening 1113 to clamp the battery cell along the first direction H1.

[0059] The housing 21 of the battery pack 2 includes four outermost side beams and an expansion beam in the middle. Since some parts of the battery pack 2 require additional space for BMS components or liquid cooling pipes, the battery cells are not necessarily attached to all the side beams and expansion beams. Therefore, this embodiment of the invention provides an opening 1113 on the second bearing position 1112, allowing the first clamping member 12 to pass through the opening 1113. Utilizing the remaining space within the battery pack 2, the battery cells inside the housing 21 are clamped and compressed without affecting the installation of the side beams and expansion beams, thus facilitating the installation of the housing 21 within the battery pack 2. Understandably, the opening 1113 also allows the assembly equipment 1 in this embodiment to clamp battery packs 2 of different sizes. For example, if the battery pack 2 is small, the first clamping member 12, which passes through the opening 1113, is used to clamp the cells inside the battery pack 2; if the battery pack 2 is large, the first clamping member 12 can be moved to the outside of the substrate 11 to clamp the cells inside the battery pack 2.

[0060] In some embodiments, refer to Figures 1 to 5 The assembly equipment 1 also includes a limiting rod 13, which extends along the first direction H1, and the first clamping members 12 are all slidably installed on the limiting rod 13.

[0061] Based on this, the limiting rod 13 can provide precise guidance and stable support for the movement of the first clamping member 12. Since the limiting rod 13 extends along the first direction H1, it can ensure that the first clamping member 12, which is slidably mounted on the limiting rod 13, moves along the first direction H1. This prevents the first clamping member 12 from deflecting, tilting or other abnormal situations during compression, ensuring that the pressure on both sides of the cell is accurately applied to the cell, reducing the probability of cell damage due to uneven force, and improving the consistency of battery pack 2 assembly.

[0062] In some alternative embodiments, there are multiple limiting rods 13, and all of the multiple limiting rods 13 extend along the first direction H1. The first clamping member 12 is slidably mounted on the multiple limiting rods 13, thereby further improving the stability of the first clamping member 12 in clamping the battery cell.

[0063] In some embodiments, refer to Figures 1 to 5 The limiting rod 13 is located on the side of the substrate 11 away from the battery cell.

[0064] Based on this, the surface of the substrate 11 is kept clean and flat, preventing the limiting rod 13 from having a negative impact on the installation of the battery cell and the housing 21. It also makes it easier for users to observe the movement of the first clamping member 12 and the installation of the battery cell and the housing 21 during the installation of the battery pack 2, thereby improving the safety of the battery pack 2 installation process.

[0065] In some embodiments, refer to Figures 1 to 5 The assembly equipment 1 further includes at least two second clamping members 14, which are arranged opposite each other along the second direction H2, so that the battery cell can be installed between at least two first clamping members 12, so that the at least two second clamping members 14 can clamp the battery cell along the second direction H2; the first direction H1 and the second direction H2 intersect.

[0066] By setting a second clamping member 14 arranged opposite to the second direction H2 intersecting the first direction H1, the second clamping member 14 and the first clamping member 12 can cooperate with each other to clamp and compress multiple sides of the battery cell, so that the size of the battery cell module composed of multiple battery cells meets the requirements, and avoids the problem of local stress concentration or assembly failure of the battery cell due to unidirectional compression of the battery cell.

[0067] Specifically, the arrangement of the second clamping member 14 varies depending on the type of battery cell. If the battery cell is square, the second clamping member 14 is positioned along a second direction H2 perpendicular to the first direction H1, thereby ensuring that the shape of the battery cell remains unchanged after clamping and reducing the probability of battery cell damage. If the battery cell is cylindrical, the position of the second clamping member 14 can be selected according to design requirements.

[0068] In some embodiments, refer to Figures 1 to 5The bearing position 111 is provided with a limiting groove 1114, which is used to install the electrode post of the battery cell.

[0069] Based on this, the battery cell is mounted with the side of the electrode post facing the substrate 11, that is, it is placed upside down on the substrate 11. This facilitates the installation of the bottom plate in the housing 21 onto the bottom surface of the battery cell without affecting the installation of the battery cell.

[0070] For example, the specific installation process is as follows: First, the battery cell is flipped onto the substrate 11. Then, the first clamping member 12 and the second clamping member 14 are controlled to clamp and compress the battery cell. Finally, adhesive is applied to the bottom surface of the battery cell, and the base plate is installed on the bottom surface of the battery cell to complete the installation of the base plate. Since the battery cell is placed upside down, when installing the base plate, only the lighter base plate needs to be moved to the battery cell, avoiding the problem of moving the battery cell when it is installed upright. This simplifies the assembly process of the base plate and improves the stability of the battery pack 2 during installation.

[0071] In some alternative implementations, the limiting groove 1114 is a single channel, allowing the terminals of multiple cells to be installed on the channel. This prevents damage caused by the terminal colliding with the limiting groove 1114 when the terminal moves due to compression of the cell, thereby improving the yield rate.

[0072] In some embodiments, refer to Figures 1 to 5 There are at least two limiting grooves 1114, and the at least two limiting grooves 1114 are arranged at intervals along the first direction H1, so that the two poles of the battery cell are respectively installed in the two adjacent limiting grooves 1114.

[0073] Based on this, both terminals of the battery cell have stable installation positions, making the battery cell installation more secure and reducing the probability of the battery cell shaking during the clamping process of the first clamping member 12 or the second clamping member 14, thus preventing damage to the battery cell.

[0074] In some embodiments, the width of the limiting groove 1114 is greater than or equal to 5 mm and less than or equal to 80 mm.

[0075] If the width of the limiting groove 1114 is less than 5mm, the limiting groove 1114 is too narrow and is prone to collision with the terminal of the battery cell; if the width of the limiting groove 1114 is greater than 80mm, the limiting groove 1114 is too wide and cannot play a good limiting role for the terminal. Therefore, in this embodiment of the utility model, the width of the limiting groove 1114 is set to be greater than or equal to 5mm and less than or equal to 80mm. For example, it can be 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, etc., thereby ensuring the limiting effect on the terminal while reducing the probability of the terminal colliding with the groove wall of the limiting groove 1114 and improving the stability of the battery cell installation.

[0076] In some embodiments, refer to Figures 1 to 5 The battery pack 2 also includes a liquid cooling plate, which is disposed between the cells and / or between the cells and the housing 21. The assembly equipment 1 also includes a first limiting member 15, which is provided between at least two adjacent limiting grooves 1114. The first limiting member 15 is used to limit the liquid cooling plate.

[0077] By setting the first limiting member 15 to limit the liquid cooling plate, the position of the liquid cooling plate on the side of the battery cell is restricted, ensuring that the liquid cooling plate is aligned with the corresponding area of ​​the battery cell, thereby improving the cooling effect of the liquid cooling plate on the battery cell.

[0078] The first limiting member 15 can be a groove, a protrusion, a retaining edge, or a pin, etc., and this utility model embodiment does not limit it.

[0079] In some embodiments, refer to Figures 1 to 5 The first limiting member 15 protrudes from the end of the substrate 11. Based on this, the first limiting member 15 provides a stable positioning reference for the installation of the liquid cooling plate. The protruding first limiting member 15 can block and limit one or more sides of the liquid cooling plate, thereby precisely constraining the position of the liquid cooling plate and effectively preventing it from sliding or shifting. Furthermore, the first limiting member 15 being located at the end of the substrate 11 reduces the probability of the battery cell colliding with the first limiting member 15 during installation, thereby improving the stability and safety of the battery pack 2.

[0080] In some embodiments, refer to Figures 1 to 5 The assembly equipment 1 also includes a second limiting member 16, which is provided between at least two adjacent limiting grooves 1114, and the second limiting member 16 extends along the first direction H1 and is disposed on the substrate 11 to support the liquid cooling plate.

[0081] The liquid cooling plate is used to cool the sides of the battery cell. Since the bottom of the battery cell usually generates less heat, the size of the liquid cooling plate is usually slightly smaller than the side dimensions of the battery cell. In order to enable the liquid cooling plate to cool the middle area of ​​the battery cell, this embodiment of the invention provides a second limiting member 16 to raise the liquid cooling plate so that it covers the middle area of ​​the battery cell, thereby improving the cooling effect of the liquid cooling plate.

[0082] Furthermore, since there may be multiple liquid cooling plates, multiple second limiting members 16 can be set to control multiple liquid cooling plates at the same height, which facilitates the connection of subsequent liquid cooling pipelines.

[0083] In some embodiments, refer to Figures 1 to 5 The first limiting member 15 and the second limiting member 16 are spaced apart, and an accommodating space 161 is formed between the first limiting member 15 and the second limiting member 16 to accommodate at least a portion of the liquid cooling plate.

[0084] Due to manufacturing precision requirements, the bottom surface of the liquid cooling plate may not be a perfectly flat plane. Therefore, this embodiment of the invention provides a receiving space 161 to accommodate uneven areas of the liquid cooling plate, thereby improving the stability of the liquid cooling plate installation. For example, the liquid cooling plate typically includes a body and a plug. The plug is used to seal the liquid cooling pipes within the body. Therefore, the plug and the body are connected by adhesive or welding, which often results in a protrusion at the connection point. This protrusion can be accommodated within the receiving space 161, facilitating the installation of the liquid cooling plate.

[0085] In some embodiments, refer to Figures 1 to 5 The assembly equipment 1 also includes a third limiting member 17, which is provided between at least two adjacent limiting grooves 1114 to limit the battery cell in the first direction H1.

[0086] By setting the third limiting member 17 to provide positioning and lateral support for the battery cell, the stability of the battery cell when placed on the substrate 11 is ensured, the probability of the battery cell tipping over is reduced, and the first clamping member 12 is then used to clamp the battery cell.
