Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a module splicing module and a module stacking device. Background Technology

[0002] With the rapid development of new energy technologies, battery packs, as important energy devices, have been widely used in electric vehicles, energy storage systems, and other fields. A battery pack typically consists of modules composed of multiple individual battery cells, which can then be further combined to form a complete battery pack. Module assembly is one of the key steps in the battery pack assembly process. However, current technologies present some technical challenges in the module assembly process.

[0003] Firstly, in the existing battery module assembly process, different modules need to be stacked together and placed in the same compaction stacking platform. During module stacking, connecting components need to be placed between the module stacks to ensure electrical connection and structural stability. However, due to the limitations of a single stacking platform, the fixation of the connecting components is often hindered, which not only reduces the module assembly speed but may also affect the assembly quality of the modules.

[0004] Secondly, existing battery module splicing technologies typically employ a single-row stacking method for individual battery cells. While this splicing method is simple, it suffers from poor compatibility. Because different modules may differ in size, shape, and electrical characteristics, achieving good compatibility during splicing is difficult, thus limiting the performance and application range of the battery pack.

[0005] Therefore, in response to the above-mentioned technical problems, there is an urgent need to propose an improvement scheme to enhance the efficiency and compatibility of module assembly, thereby improving the overall performance and application value of the battery pack. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a module splicing module and a module stacking device to improve the efficiency and compatibility of module assembly, thereby enhancing the overall performance and application value of the battery pack.

[0009] At least two positioning components are respectively disposed on both sides of the battery cell stacking platform along the sliding direction of the battery cell stacking platform, and can be movably extended into the sliding area of ​​the battery cell stacking platform to stop the battery cell stacking platform from sliding.

[0010] Furthermore, the positioning component includes a positioning slider, a positioning guide rail, and a driving component;

[0011] The positioning slider is mounted on the positioning guide rail and can extend movably into the sliding area of ​​the cell stacking platform via the positioning guide rail;

[0013] Furthermore, the driving component is a manual driving component or an automatic driving component;

[0014] The manual drive component is an operating lever, which is mounted on the positioning slider.

[0015] Furthermore, the positioning component also includes a locking component;

[0016] The locking component is connected to the positioning slider and is used to lock the positioning slider when the positioning slider slides into position.

[0017] Furthermore, the locking assembly includes a first locking element and a second locking element;

[0018] The first locking element is disposed on the side of the positioning guide rail facing away from the cell stacking platform;

[0019] The second locking member is installed on the side of the positioning slider that faces away from the cell stacking platform;

[0020] When the second locking member moves a preset distance relative to the first locking member, it can lock and engage with the first locking member.

[0021] Furthermore, the first locking member is provided with at least two first locking structures arranged sequentially along the sliding direction of the positioning slider;

[0022] The second locking member is provided with a second locking structure that can be locked and connected with the first locking structure.

[0023] Furthermore, the second locking structure is a card;

[0024] The card is slidably mounted on the second locking member and is connected to the second locking member through an elastic member;

[0025] The first locking structure is a slot for the card to be inserted;

[0026] The card is configured to disengage from the slot when the positioning slider is subjected to a preset force in the sliding direction.

[0027] Furthermore, there are four positioning components, which are arranged in pairs on both sides of the cell stacking platform;

[0028] The two positioning components located on the same side are symmetrically arranged with respect to the cell stacking platform.

[0029] This application also discloses a module stack splicing device, including a first splicing module stack and a second splicing module stack;

[0030] The first assembly module stack includes a first support plate;

[0031] The second splicing module stack includes a second support plate, a second sliding component, and a third support plate;

[0032] The module splicing module is installed on both the first support plate and the third support plate;

[0033] The third support plate is slidably mounted on the second support plate via the second sliding component;

[0034] The cell stacking platform on the third support plate can be connected to the cell stacking platform on the second support plate by sliding the third support plate.

[0035] Furthermore, the third support plate is provided with a protruding plate portion along its sliding direction;

[0037] At least one positioning component located on the first support plate can engage and abut against the limiting step when the cell stacking platform on the third support plate is spliced ​​with the cell stacking platform on the second support plate.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0054] This application discloses a module splicing module.

[0055] Please see Figure 1 One embodiment of a module splicing module provided in this application includes:

[0056] Cell stacking platform 1, first sliding component 3, and positioning component 2.

[0057] The cell stacking platform 1 is mounted on the first sliding assembly 3. The first sliding assembly 3 is an existing sliding assembly structure, including a first guide rail 31 and a first slider 32, used to realize the sliding of the cell stacking platform 1 in a specified direction. The first guide rail 31 is fixedly installed, and the first slider 32 is fixedly connected to the cell stacking platform 1. The first slider 32 is slidably installed on the first guide rail 31, so that the cell stacking platform 1 can slide along the guide rail.

[0058] At least two positioning components 2 are respectively disposed on both sides of the battery cell stacking platform 1 along the sliding direction of the battery cell stacking platform 1, and can be movably extended into the sliding area of ​​the battery cell stacking platform 1 to stop the battery cell stacking platform 1 from sliding.

[0059] The modular splicing module designed in this application has the following beneficial effects:

[0060] 1. The first sliding component 3 allows for flexible adjustment of the cell stacking platform 1. This means that during module installation, the cell stacking platform 1 can be moved to a suitable position according to actual needs, facilitating the installation of module stacks on the cell stacking platform 1. At the same time, under the action of the first sliding component 3, module stacks between different stacking platforms can be accurately and flexibly aligned, thereby enabling the rapid assembly of module stacks of different sizes.

[0061] 2. There are at least two positioning components 2, located on both sides along the sliding direction of the cell stacking platform 1, and capable of extending into the sliding area to stop the cell stacking platform 1 from sliding. This design enables rapid positioning of the cell stacking platform 1. During assembly, the rapidly positioned cell stacking platform 1 can accelerate the assembly speed. Rapid positioning ensures accurate positioning for each assembly, eliminating the need for repeated adjustments and improving module assembly efficiency.

[0062] The above is an embodiment of a module splicing module provided in this application. The following is an embodiment of a module splicing module provided in this application. Please refer to the following for details. Figures 1 to 4 .

[0063] Based on the solution of Embodiment 1 above:

[0064] Furthermore, such as Figures 2 to 4 As shown, the structural design of the positioning component 2 includes a positioning slider 21, a positioning guide rail 22, and a driving component 23.

[0065] The positioning slider 21 is slidably mounted on the positioning guide rail 22 and can extend into the sliding area of ​​the cell stacking platform 1 through the positioning guide rail 22. The top surface of the positioning guide rail 22 is lower than the bottom surface of the cell stacking platform 1 and will not affect the sliding of the cell stacking platform 1. However, when the positioning slider 21 slides into the sliding area of ​​the cell stacking platform 1, it can block the sliding of the cell stacking platform 1.

[0066] The driving component 23 is connected to the positioning slider 21 and is used to drive the positioning slider 21 to slide.

[0067] The sliding direction of the positioning slider 21 can be perpendicular to the sliding direction of the cell stacking platform 1. That is, the positioning guide rail 22 is arranged perpendicular to the first guide rail 31. With the first guide rail 31 as the X-axis, the positioning guide rail 22 is arranged along the Y-axis.

[0068] Furthermore, the drive unit 23 can be a manual drive unit or an automatic drive unit.

[0069] Manually driven components, such as levers, are convenient for workers to operate directly, while automatic driven components enable automated control and improve work efficiency. In practical applications, the appropriate driving method can be selected according to specific needs. When positioning the cell stacking platform 1 is required, simply drive the positioning slider 21 to slide along the positioning guide rail 22 to the sliding area of ​​the cell stacking platform 1; the operation is simple and quick.

[0070] Furthermore, the manual drive component is an operating lever, which is mounted on the positioning slider 21. When it is necessary to drive the positioning slider 21 to slide, the operator only needs to hold the operating lever and apply pushing or pulling force to make the positioning slider 21 slide along the positioning guide rail 22, thereby realizing the positioning operation of the cell stacking platform 1.

[0071] Furthermore, such as Figure 2 As shown, the positioning component 2 also includes a locking component 26; the locking component 26 is connected to the positioning slider 21 and is used to lock the positioning slider 21 when the positioning slider 21 slides into position.

[0072] The locking component 26 ensures that the positioning slider 21 remains stable after sliding into position, preventing slippage or displacement. This allows the cell stacking platform 1 to maintain accurate positioning during assembly, further improving the efficiency and accuracy of module assembly.

[0073] In practical applications, the locking component 26 can adopt various structural forms, as long as it can achieve the locking function of the positioning slider 21. For example, it can adopt a latch, locking pin, or other structural forms to lock the positioning slider 21 to the positioning guide rail 22 or other fixed structures. A preferred structural configuration is described below:

[0074] The locking component 26 includes a second locking member 25 and a first locking member 24; the first locking member 24 is disposed on the side of the positioning guide rail 22 facing away from the cell stacking platform 1; the second locking member 25 is mounted on the side of the positioning slider 21 facing away from the cell stacking platform 1; when the second locking member 25 moves a preset distance relative to the first locking member 24, it can lock and cooperate with the first locking member 24.

[0075] Furthermore, regarding the locking engagement design between the first locking member 24 and the second locking member 25, the first locking member 24 may be provided with at least two first locking structures 241 arranged sequentially along the sliding direction of the positioning slider 21; while the second locking member 25 may be provided with a second locking structure 251 that can be locked and connected with the first locking structure 241.

[0076] When the position of the positioning slider 21 needs to be fixed, slide the positioning slider 21 to a suitable position, so that the second locking structure 251 on the second locking member 25 is locked to the corresponding first locking structure 241 on the first locking member 24. Since there are at least two first locking structures 241 and they are arranged along the sliding direction of the positioning slider 21, a suitable locking position can be selected according to specific needs. After locking, the positioning slider 21 and the positioning guide rail 22 are relatively fixed, avoiding interference with operations such as cell stacking due to accidental sliding of the positioning slider 21, and ensuring the smooth progress of related work. When the position of the positioning slider 21 needs to be readjusted, release the lock between the second locking structure 251 and the first locking structure 241, and then slide the positioning slider 21 to a new position and relock it.

[0077] Furthermore, such as Figures 3 to 4 As shown, the second locking structure 251 is a clip; the clip is slidably installed on the second locking member 25 and is connected to the second locking member 25 through an elastic member (not shown in the figure).

[0078] The first locking structure 241 is a slot for inserting a locking element. The locking element is configured to disengage from the slot when a preset force (more than 20N applied via the drive member 23) is applied in the sliding direction of the positioning slider 21. It can be understood that the force applied via the drive member 23 to drive the positioning slider 21 to slide is, for example, a manual lever design. This means grasping the lever and applying force in the direction the positioning slider 21 is to slide. When the component of the applied force in the sliding direction of the positioning slider 21 is greater than a preset value (e.g., greater than 20N), the locking element will disengage from the slot.

[0079] The locking element is slidably mounted on the second locking element 25 and connected to it via an elastic element, allowing the locking element a certain amount of room to move and a reset capability. The elastic element plays a crucial role, providing a spring force to hold the locking element in a certain position. The slot serves as the locking position for the locking element, positioning and restricting it. When the locking element is engaged in the slot, the locking function is achieved.

[0080] The disengagement mechanism of the card is that when the positioning slider 21 is subjected to a preset force in the sliding direction, this external force overcomes the elastic force of the elastic element, allowing the card to disengage from the slot; when the external force is greater than the elastic force of the elastic element, the state of the card changes, thereby unlocking.

[0081] This design connects the locking element and the second locking element 25 via an elastic element, allowing the locking element to slide flexibly and remain locked when no external force is applied. This provides a stable locking mechanism, ensuring the secure connection of related components under normal use. The pre-set force release design (applied via the drive element 23 for forces exceeding 20N) is controllable. The locking element will only disengage from the slot under specific external force conditions, avoiding accidental locking due to unforeseen forces and improving the safety and reliability of the equipment. The overall structure is simple and straightforward, consisting of common locking elements, slots, and elastic elements, making it easy to manufacture and maintain, reducing production costs and maintenance difficulty, and facilitating large-scale production and application of the product.

[0082] The cooperation between the aforementioned locking components and elastic elements can be referenced to the spring-loaded ball in the main shaft of a folding umbrella. Its cooperation with the positioning hole allows the main shaft to lock in place when extended or retracted, and when a certain force is applied, the spring-loaded ball can be disengaged from the positioning hole. This is similar to the working principle between the locking component and the slot in this case. To ensure smooth disengagement of the locking component from the slot, both the end of the locking component and the slot are designed with an arc shape. The arc structure provides a guiding function. Those skilled in the art can refer to existing designs and make appropriate adjustments and modifications, which will not be elaborated upon here.

[0083] Furthermore, such as Figure 1 As shown, there are four positioning components 2, arranged in pairs on both sides of the cell stacking platform 1; the two positioning components 2 on the same side are symmetrically arranged relative to the cell stacking platform 1. In practical applications, the four positioning components 2 can more comprehensively cover the four sides of the cell stacking platform 1, making the positioning process smoother and more efficient.

[0084] like Figure 1 , Figures 5 to 8 This application also discloses a module stack splicing device, including a first splicing module stack and a second splicing module stack.

[0085] like Figure 1 As shown, the first assembly module stack includes a first support plate 41; as Figure 5 as well as Figure 6 As shown, the second splicing module stack includes a second support plate 42, a second sliding component 5, and a third support plate 43.

[0086] Both the first support plate 41 and the third support plate 43 are equipped with module splicing modules; the third support plate 43 is slidably installed on the second support plate 42 via the second sliding component 5; the cell stacking platform 1 on the third support plate 43 can be spliced ​​with the cell stacking platform 1 on the second support plate 42 by sliding the third support plate 43.

[0087] The first slide rail of the first sliding component 3 is fixedly installed on the first support plate 41.

[0088] The second sliding assembly 5 is the same as the first sliding assembly 3, including a second guide rail 51 and a second slider 52, used to realize the sliding of the third support plate 43 in a specified direction. The second guide rail 51 is fixedly installed on the second support plate 42, and the second slider 52 is fixedly connected to the third support plate 43. The second slider 52 is slidably installed on the second guide rail 51, realizing the sliding of the third support plate 43 along the guide rail.

[0089] The sliding direction of the third support plate 43 can be perpendicular to the sliding direction of the cell stacking platform 1, that is, the second guide rail 51 is arranged perpendicular to the first guide rail 31. The advantage of this design is that it allows for flexible position adjustment of the cell stacking platform 1 in both the X-axis direction (direction of the first guide rail 31) and the Y-axis direction (direction of the second guide rail 51). During module stacking, the cell stacking platform 1 on the third support plate 43 can first be initially aligned with the cell stacking platform 1 on the second support plate 42 by sliding the third support plate 43. Then, the position of the cell stacking platform 1 in the X-axis direction is adjusted by the first sliding component 3 to ensure complete alignment of the two cell stacking platforms 1 before final assembly. This design not only improves the flexibility of module stacking but also ensures the accuracy and efficiency of the assembly.

[0090] like Figure 1 , Figure 5 as well as Figure 6 As shown, taking the design of four positioning components 2 of the module splicing module as an example, the four corner positions of the first support plate 41 and the four corner positions of the third support plate 43 can be arranged respectively.

[0091] Furthermore, such as Figure 7 as well as Figure 8 As shown, the third support plate 43 has a protruding plate portion 44 along its sliding direction; the bottom of the protruding plate portion 44 has a limiting step 45; when at least one positioning component 2 located on the first support plate 41 is spliced ​​with the cell stacking platform 1 on the third support plate 43 and the cell stacking platform 1 on the second support plate 42, it can be fitted and abutted with the limiting step 45; when the positioning component 2 is fitted and abutted with the limiting step 45, it can be considered to be spliced ​​in place.

[0092] Two protruding plates 44 can be designed and distributed at two corners on one side of the third support plate 43, forming a concave structure between them and one side of the third support plate 43 to avoid splicing the cell stacking platform 1 on the first support plate 41.

[0093] Taking the four positioning components 2 on the first support plate 41 as an example, the two positioning components 2 near the second support plate 42 respectively cooperate with the limiting step 45 at the bottom of the protruding plate portion 44. Taking the driving component 23 as an operating lever as an example, its installation method can be to be vertically fixed to the top of the positioning slider 21 (e.g. Figure 3 as well as Figure 4 (As shown), however, this fixing method will interfere with the movement of the protruding plate 44. Therefore, for the positioning assembly 2 that cooperates with the protruding plate 44, the operating rod on its positioning slider 21 can be one side of the positioning slider 21 and its height is not higher than the top surface of the positioning slider 21 (as shown). Figure 2 (As shown).

[0094] The module stack splicing device of this application, by designing the first splicing module stack and the second splicing module stack to cooperate, can realize the splicing of module stack modules, thereby achieving rapid splicing; it can also adapt to the splicing of module stacks of different sizes, and achieve the assembly air-avoidance effect.

[0095] In addition, in this application, the sliding displacement of the first sliding component 3 and the second sliding component 5 can be detected by displacement sensors such as grating sensors, so that the control of their sliding displacement is more accurate, and no specific limitation is made.

[0096] The above provides a detailed description of a module splicing module and a module stacking device provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
