Description

Technical Field

[0001] This utility model relates to the field of power battery technology, specifically to a device for stacking double-row vertical soft-pack modules. Background Technology

[0002] Pouch cells are widely used in various power battery modules due to their advantages such as high energy density and light weight. Among them, the stacking process of pouch cells is a key step in the module assembly process, which directly affects the structural stability, electrical performance consistency and production efficiency of the module.

[0003] Currently, in the stacking methods of pouch cells, horizontal stacking (i.e., cells arranged along the Z-axis in the thickness direction) is widely used in single-row module assembly due to its relatively simple operation. However, as the requirements for energy density and structural compactness of power batteries continue to increase, double-row vertical stacking (i.e., cells arranged along the Z-axis in the large area) is gradually becoming an important direction for optimizing module space utilization.

[0004] Although the double-row vertical stacking design has potential in optimizing module space utilization, it still faces many technical challenges in the actual stacking process, as follows: (1) The existing double-row vertical stacking design adopts the operation method of "stacking a single row and then combining it into a double row", that is, first stacking horizontally to form a single row module, then wrapping the single row module with tape, and finally combining the two single row modules into a double row module. This method has many problems that can easily lead to cell misalignment: during the combination of single row modules, the cells are prone to displacement, which leads to incorrect cell position; during the movement of single row modules, relative displacement between cells is very likely to occur; and because the space is small after the double row modules are combined, it is difficult to effectively restrain the single row modules, which further causes misalignment between cells during the combination process. Once misalignment occurs between cells, the tabs (Note: tabs refer to the metal conductive terminals led out from the positive and negative electrode plates of the lithium-ion battery, which are the key connection components for energy transmission between the cell and the external circuit) will be bent and misaligned, which greatly increases the welding difficulty. Since the tabs are double-layered and bent together, if the cells are stacked and misaligned, the folded area of ​​the tabs will become smaller, and the effective area for soldering will also be reduced accordingly. This can easily lead to burn-through, or insufficient soldering area, resulting in insufficient current carrying capacity and overheating. Ultimately, this will have an adverse effect on the electrical performance of the module.

[0005] (2) The double-row vertical soft package module usually shares one end plate, which makes the gap between the two rows extremely small. If the two rows are stacked at the same time, there will be insufficient operating space and precise assembly cannot be achieved.

[0006] (3) Due to the irregular shape of the soft-pack battery cell, its stacking positioning reference needs to rely on a specific position. However, the double-row vertical module is difficult to achieve effective positioning during the stacking process, which affects the accuracy of stacking. Utility Model Content

[0007] The present invention aims to provide a device for stacking double-row vertical soft pack modules, so as to solve the problems of complex operation, inaccurate positioning and easy displacement of double-row vertical soft pack module stacking in the prior art.

[0008] To solve the above problems, the present invention adopts the following technical solution: a device for stacking double-row vertical soft-pack modules, used to vertically stack double-row parallel soft-pack cells; the device includes a suction cup and a stacking platform, the suction cup is located above the stacking platform, and the stacking platform includes a stacking area and a cell area; A stacking platform is provided in the middle of the stacking area for receiving two rows of parallel soft-pack battery cells and performing vertical stacking simultaneously. The stacking platform has first guide pins extending vertically on both sides. A battery cell platform is provided in the middle of the battery cell area for placing two rows of parallel soft-pack battery cells to be stacked. The battery cell platform has second guide pins extending vertically on both sides. The suction cup has pin holes on both sides corresponding to the first guide pin and the second guide pin. When stacking soft-pack battery cells, the suction cup lowers and positions itself to pick up the soft-pack battery cells through the cooperation of the pin holes and the second guide pin. Then the suction cup moves to the stacking area, lowers and positions itself to stack the soft-pack battery cells through the cooperation of the pin holes and the first guide pin.

[0009] The principle of this solution is as follows: First, the operator places two soft-pack battery cells on the battery cell platform, then starts the suction cup and moves it above the battery cell area. At this time, the second guide pin cooperates with the pin hole to guide the suction cup to descend accurately, ensuring that the positioning between the soft-pack battery cell and the suction cup is accurate, thereby stably picking up the soft-pack battery cell. After adsorption is complete, the operator moves the suction cup and the pouch cell together to the stacking platform. During this process, the suction cup is guided down by the first guide pin and the pin hole, stacking the pouch cell on the stacking platform.

[0010] The advantages of this solution are: (1) This solution achieves simultaneous pick-up and stacking of double-row soft-pack cells by setting up a double-row parallel layout of the cell platform and the stacking platform; compared with the existing stacking method, this design significantly reduces the number of stacking processes through parallel operation, significantly improves stacking efficiency, and effectively reduces production time costs. At the same time, since soft-pack cells have high requirements for process protection, this layout avoids the risk of damage to soft-pack cells during the traditional handling process, thereby better ensuring the integrity and yield of soft-pack cells.

[0011] (2) This solution ensures the positioning accuracy of the suction cup during the picking and stacking process by using the cooperation between the guide pins (i.e., the first guide pin and the second guide pin) and the pin holes. Whether picking up materials from the cell platform or placing materials on the stacking platform, stable positioning can be achieved through the corresponding cooperation between the first guide pin, the second guide pin and the pin holes, avoiding problems such as cell offset and damage caused by positioning deviation during the stacking process, ensuring the neatness and stability of the double-row soft-pack cell stacking, and improving the quality of module stacking.

[0012] (3) The structure of this solution is simple and easy to operate: the whole device is mainly composed of core components such as suction cup, stacking platform, battery cell platform and guide pin. It has a compact structure and is easy to manufacture and maintain. Its operation process can complete the continuous action of positioning, picking up and stacking through the cooperation of suction cup and guide pin. There is no need for complicated control program or additional auxiliary mechanism, which simplifies the operation process and reduces the skill requirements of the operator.

[0013] Preferably, as an improvement, the top of the cell platform is provided with positioning grooves arranged side by side, the shape of which is adapted to the bottom shape of the soft-pack cell, for pre-positioning the soft-pack cell.

[0014] Beneficial effects: The positioning slot can quickly and accurately position each pouch cell initially, effectively preventing the pouch cells from shifting or tilting before stacking, improving the overall stacking consistency, and simplifying the operation process for operators to place pouch cells. This allows operators to complete the arrangement of pouch cells more quickly, reduce the time spent on repeated adjustments, and improve assembly efficiency, thus providing a unified and reliable positioning basis for the stacking process.

[0015] Preferably, as an improvement, the thickness of the positioning groove is 2mm-4mm.

[0016] Beneficial effects: The reasonable slot thickness design can ensure effective embedding of the pouch cell at the bottom while taking into account structural strength and positioning accuracy. This ensures that pouch cells from different batches can be smoothly placed into the positioning slot, avoiding assembly difficulties or damage to the cells due to excessive tightness. It also ensures that the pouch cells maintain the correct posture before stacking, providing a stable foundation for subsequent stacking.

[0017] Preferably, as an improvement, a guide sleeve is provided inside the pin hole, the inner diameter of the guide sleeve being adapted to the diameter of the pin hole, and the outer diameter of the guide sleeve being adapted to the diameter of the first guide pin and the second guide pin.

[0018] Beneficial effects: The guide sleeve allows the guide pins (i.e., the first guide pin and the second guide pin) to slide smoothly along the inner wall of the sleeve when inserted into the pin hole, avoiding offset or jamming caused by excessive gap between the pin hole and the guide pin, thereby improving guiding accuracy and stacking consistency; and can effectively reduce direct friction and collision between the guide pin and the pin hole, preventing the inner wall of the pin hole from wearing or deforming due to long-term use, and extending the service life of the equipment.

[0019] Preferably, as an improvement, the height of the first guide pin is greater than the sum of the height of the stacking platform itself and the total thickness of the stacked pouch cells, and the height of the second guide pin is greater than the thickness of the pouch cells.

[0020] Beneficial effects: The first guide pin is higher than the total stacking height, ensuring that the cell stacking surface is always exposed throughout the stacking process, providing continuous guidance for the subsequent placement of pouch cells; the second guide pin, although slightly shorter than the first guide pin, is higher than the thickness of a single cell layer, providing guidance for the initial positioning of each cell layer and preventing displacement; the height design of the first guide pin is redundant, which can adapt to the stacking requirements of pouch cells with different numbers of layers, improving the versatility and flexibility of the tooling, and is suitable for the assembly of multiple module models.

[0021] Preferably, as an improvement, the stacking area further includes marker posts, which are diagonally distributed at one end of the first guide pin.

[0022] Beneficial effects: Diagonally distributed marker posts provide reference indicators for cell polarity during cell stacking, effectively preventing assembly problems caused by incorrect polarity identification. In other words, clear visual guidance allows operators to quickly and accurately determine cell polarity during stacking, reducing assembly errors caused by polarity confusion and providing a reliable guarantee for the correctness of cell stacking.

[0023] Preferably, as an improvement, the height of the marking post is greater than the sum of the height of the stacking platform itself and the total thickness of the stacked pouch cells.

[0024] Beneficial effects: The height of the marker post is higher than the total height of the cell stack, so that it always protrudes from the top of the cells before the stacking is completed, providing clear visual guidance for the last layer of cells and preventing assembly problems caused by incorrect polarity identification.

[0025] Preferably, as an improvement, the blister packaging includes an adsorption plate and a suction cup handle, the suction cup handle being located above the adsorption plate.

[0026] Beneficial effects: The suction cup handle makes it easier for operators to grip and apply force when handling or transferring soft-pack battery cells, making it easier and more natural for operators to grasp and place soft-pack battery cells, reducing labor intensity, making blister packaging easier to control, and improving work efficiency; the suction plate can fit tightly against the surface of the soft-pack battery cell, and achieve a stable grip through negative pressure adsorption, avoiding the battery cell from slipping or being damaged due to shaking or tilting during transportation, thus improving operational safety.

[0027] Preferably, as an improvement, the adsorption plate has a through hole in the middle that is adapted to the arrangement of the soft-pack battery cells.

[0028] Beneficial effects: The through-hole design, while maintaining sufficient adsorption performance, effectively reduces the amount of material used in the adsorption plate, lowering its weight. This not only makes operation easier but also reduces equipment load and operator workload, thereby improving operational efficiency. Furthermore, the through-hole structure provides operators with a clear visual observation channel during transport, facilitating real-time monitoring of the battery cell's adsorption status and further enhancing operational efficiency.

[0029] Preferably, as an improvement, the through hole is square.

[0030] Beneficial effects: The square through-hole has a large opening area and regular boundaries, which helps to distribute the airflow evenly in the vacuum adsorption system, reduce airflow disturbance, and improve adsorption response speed and efficiency.

[0031] In summary, the beneficial effects of this solution are: (1) Through the ingenious design of the device (such as stacking platform, cell platform, first guide pin and second guide pin, etc.), this solution realizes high-precision, high-efficiency and high-stability double-row vertical stacking assembly of soft-pack cells, solving the problems of inaccurate positioning, complicated operation, easy misalignment and poor welding in the traditional manual stacking method.

[0032] (2) In this solution, the first guide pin and the second guide pin achieve the dual functions of positioning and guiding the descent action of the suction cup through the "pin hole-pin" cooperation structure. They are key components to ensure the accuracy and stability of the soft-pack battery cell suction process. At the same time, the two guide pins work together to control the overall stacking direction and the placement position of the single-layer battery cell respectively, ensuring that each layer of battery cell can be accurately positioned along the guide structure, significantly improving the stacking consistency and overall structural accuracy.

[0040] The reference numerals in the accompanying drawings include: suction cup 1, suction plate 11, suction cup handle 12, pin hole 13, guide sleeve 14, through hole 15, stacking platform 2, stacking area 3, stacking stage 31, first guide pin 32, identification post 33, cell area 4, cell stage 41, second guide pin 42, platform handle 5, soft-pack cell 6, soft-pack module 7. Detailed Implementation

[0041] The following detailed description illustrates the specific implementation method: In this embodiment, vertical stacking refers to the arrangement of the large surfaces of the pouch cells 6 along the Z-direction.

[0042] The implementation examples are basically as follows Figure 1 , Figure 2 As shown: A device for stacking dual-row vertical soft-pack modules includes a suction cup 1 and a stacking platform 2. The suction cup 1 is located above the stacking platform 2, and the stacking platform 2 includes a stacking area 3 and a cell area 4. A stacking platform 31 is installed in the middle of the stacking area 3 to receive two rows of parallel soft-pack cells 6 and perform vertical stacking at the same time. First guide pins 32 extending vertically are installed on both sides of the stacking platform 31. A cell platform 41 is installed in the middle of the cell area 4 to place two rows of parallel soft-pack cells to be stacked. Second guide pins 42 extending vertically are installed on both sides of the cell platform 41. The suction cup 1 has pin holes 13 on both sides corresponding to the first guide pin 32 and the second guide pin 42. When stacking soft-pack battery cells 6, the suction cup 1 lowers and positions itself and picks up the soft-pack battery cells 6 through the cooperation of the pin holes 13 and the second guide pin 42. Then the suction cup 1 moves to the stacking area 3, lowers and positions itself and stacks the soft-pack battery cells 6 through the cooperation of the pin holes 13 and the first guide pin 32.

[0043] Specifically, such as Figure 2 As shown, the stacking platform 2 includes a stacking area 3 and a cell area 4. The stacking area 3 is used for vertical stacking, and the cell area 4 is used to place the pouch cells 6 to be stacked.

[0044] The stacking area 3 includes a stacking platform 31, a first guide pin 32, and a marker post 33. The stacking platform 31 is located in the middle of the stacking area 3 and is used to receive two rows of parallel soft-pack battery cells 6 and perform vertical stacking simultaneously. The first guide pin 32 is located on both sides of the stacking platform 31 and is used to provide a clear spatial positioning reference for the descent of the suction cup 1 in the stacking area 3, ensuring that the suction cup 1 can accurately place the soft-pack battery cell 6 into the preset stacking position (such as the alignment position with the already stacked battery cells), avoiding stacking skew or misalignment due to placement offset; and guiding the suction cup 1 to descend smoothly along a fixed trajectory (usually vertical), limiting the swaying or offset of the suction cup 1 in the horizontal direction, ensuring that the soft-pack battery cell 6 can be accurately stacked along the preset stacking axis when stacked, reducing stacking errors caused by unstable movement, thereby ensuring that each soft-pack battery cell 6 can be stacked in a uniform posture and position, maintaining the regularity of the entire stacking structure (such as large face alignment, edge alignment, etc.), and providing a stable foundation for subsequent assembly or processing procedures.

[0045] The marking posts 33 are diagonally distributed at one end of the first guide pin 32. These diagonally distributed marking posts 33 provide a reference mark for the polarity of the battery cells during stacking, effectively preventing assembly problems caused by incorrect polarity identification. In other words, through clear visual guidance, operators can quickly and accurately determine the polarity of the battery cells during stacking, reducing assembly errors caused by polarity confusion and providing a reliable guarantee for the correctness of battery cell stacking. In this embodiment, a "+" or "-" sign is affixed to the top of the marking posts.

[0046] In this embodiment, the height of the first guide pin 32 is greater than the sum of the height of the stacking platform 31 and the total thickness of the stacked pouch cells 6, providing continuous and reliable positioning and constraint for the entire stacking process. During the stacking of the pouch cells 6, the total stack thickness gradually increases as the number of pouch cells 6 increases. Since the height of the first guide pin 32 is always higher than "the height of the stacking platform 31 + the current total stack thickness," it ensures that throughout the entire stacking process (from the initial state without cells to stacking to the maximum thickness), the pin remains engaged with the pin hole 13 of the suction cup 1, continuously providing precise guidance for the descent and positioning of the suction cup 1, preventing the pin from being "submerged" and losing its guiding function due to the increase in stack thickness. It also ensures consistent stacking accuracy, ensuring that each pouch cell 6 is stacked along a preset trajectory and position, maintaining the verticality, flatness, and alignment of the entire stacking structure, and avoiding accumulated errors.

[0047] Specifically, in this embodiment, the height of the first guide pin 32 is 218mm, the height of the stacking platform 31 itself is 40mm, the total thickness of the stacked soft-pack battery cells 6 is 40mm-170mm, and the height of the marker post 33 is 190mm.

[0048] The cell area 4 includes a cell platform 41 and a second guide pin 42. The cell platform 41 is located in the middle of the stacking area 3 and is used to place double rows of soft-pack cells to be stacked. The second guide pin 42 is located on both sides of the cell platform 41 and is used to provide a clear guide reference for the descent movement of the suction cup 1, ensuring that the suction cup 1 can accurately align with the preset suction position of the soft-pack cell 6, avoiding suction deviation caused by the offset of the suction cup 1, and guiding the suction cup 1 to descend smoothly along the preset trajectory (usually in the vertical direction), limiting the swaying or offset of the suction cup 1 in the horizontal direction, ensuring the stability of the suction cup 1 during the descent process, and laying the foundation for the subsequent reliable suction of the soft-pack cell 6.

[0049] Specifically, the top of the cell platform 41 is equipped with side-by-side positioning grooves. The shape of the positioning grooves is adapted to the bottom shape of the soft-pack cell 6, and is used for pre-positioning the soft-pack cell 6. The thickness of the positioning grooves is 2mm-4mm, which forms a clear groove boundary, allowing the bottom of the soft-pack cell 6 to be accurately embedded in the groove, and restricting the horizontal displacement of the cell through the groove wall to achieve accurate pre-positioning; without the groove being too deep due to excessive thickness, which would affect the convenience of cell placement or increase the difficulty of picking up and putting down the cell. In this embodiment, the thickness of the positioning grooves is generally 1 / 3 of the thickness of the cell.

[0050] The height of the second guide pin 42 is greater than the thickness of the pouch cell 6. In this embodiment, the height of the second guide pin 42 is 69mm, and the thickness of the pouch cell 6 is 8mm-45mm. Although the second guide pin 42 is slightly shorter than the first guide pin 32, it is greater than the thickness of a single-layer cell, which can provide guidance for the initial positioning of each layer of cells and prevent displacement.

[0051] As Figure 3 、 Figure 4 shown in the figure, the suction cup 1 includes a suction plate 11 and a suction cup handle 12. The suction cup handle 12 is located above the suction plate 11. The design of the suction cup handle 12 facilitates the operator to hold and apply force when handling or transferring the soft-pack battery cell 6, thereby improving the operation efficiency and convenience; the suction plate 11 is used to closely fit with the surface of the soft-pack battery cell 6, and realizes firm grasping through negative pressure adsorption, avoiding the battery cell from slipping or being damaged due to shaking or tilting during the handling process, and improving the operation safety.

[0052] Specifically, the suction plate 11 has a "middle" character structure, and pin holes 13 corresponding to the first guide pin 32 and the second guide pin 42 are arranged on both sides thereof. A guide sleeve 14 is sleeved inside the pin hole 13. The inner diameter of the guide sleeve 14 is adapted to the aperture of the pin hole 13, and the outer diameter of the guide sleeve 14 is adapted to the diameters of the first guide pin 32 and the second guide pin 42. The setting of the guide sleeve 14 enables the guide pins (i.e., the first guide pin 32 and the second guide pin 42) to smoothly slide along the inner wall of the sleeve when inserted into the pin hole 13, avoiding deviation or jamming caused by excessive clearance between the pin hole 13 and the guide pins, thereby improving the guiding accuracy and stacking consistency; at the same time, the guide sleeve 14 can effectively reduce the direct friction and collision between the guide pins and the pin hole 13, prevent the inner wall of the pin hole 13 from being worn or deformed due to long-term use, and extend the service life of the equipment.

[0053] A through hole 15 adapted to the arrangement of the soft-pack battery cells 6 is arranged in the middle of the suction plate 11. The through hole 15 is square. The setting of the through hole 15 can effectively reduce the material consumption of the suction plate 11 and reduce its own weight on the premise of meeting the adsorption performance. This not only makes the operation more convenient, but also reduces the equipment load and the operation intensity of personnel, thereby improving the operation efficiency. In addition, the through hole structure can provide a visually transparent observation channel for the operator during the handling process, facilitating the real-time observation of the adsorption state of the battery cells and further improving the operation efficiency.

[0054] In addition, as Figure 5 shown in the figure, a number of platform handles 5 are installed on both sides of the stacking platform 2. Specifically, 2 platform handles 5 are symmetrically distributed on one side of the stacking platform 2, which not only ensures the force balance during handling, but also provides a convenient force application point for the operator, facilitating the handling and moving of the device.

[0055] Specific implementation process: (1) Preparation stage: 2 soft-pack battery cells 6 are placed on the battery cell table 41, and the bottom of the soft-pack battery cells 6 is embedded in the positioning grooves to achieve preliminary positioning; at the same time, end plates are placed on the stacking table 31 to prepare for subsequent stacking.

[0056] (2) Handling and stacking stage: As Figure 6As shown, when the suction cup 1 is activated, the operator moves the suction cup 1 above the cell area 4 using the suction cup handle 12. At this time, guided by the cooperation between the second guide pin 42 and the pin hole 13, the suction cup 1 descends along the second guide pin 42 to pick up the soft-pack cell 6, ensuring that the positioning between the soft-pack cell 6 and the suction cup 1 is accurate. Subsequently, the operator moves the adsorbed pouch cell 6 as a whole to the stacking platform 31. During this process, the suction cup 1 is guided by the cooperation between the first guide pin 32 and the pin hole 13, descends along the first guide pin 32, and stacks the pouch cell 6 on the end plate to ensure the precise relative position between the pouch cell 6 and the end plate.

[0057] Then repeat the above operation to stack the soft-pack cells 6, and ensure that the relative positions of the stacked cells are accurate to avoid stacking misalignment, thereby ensuring the smooth progress of subsequent welding processes.

[0058] like Figure 7 As shown, after the stacking of the pouch cells 6 is completed, the pouch module 7 is assembled.

[0059] In summary, this solution, through the ingenious design of the device (such as the stacking platform 31, the cell platform 41, the first guide pin 32, and the second guide pin 42), achieves high-precision, high-efficiency, and high-stability vertical stacking assembly of double-row soft-pack battery cells 6, solving problems such as inaccurate positioning, complex operation, easy misalignment, and poor welding in traditional manual stacking methods. This solution ensures the positioning accuracy of the suction cup 1 during the picking and stacking process through the cooperation between the guide pins (i.e., the first guide pin 32 and the second guide pin 42) and the pin holes 13. Whether picking up materials from the cell platform 41 or placing materials onto the stacking platform 31, stable positioning can be achieved through the corresponding cooperation between the first guide pin 32, the second guide pin 42, and the pin holes 13, avoiding problems such as cell offset and damage caused by positioning deviations during stacking, ensuring the neatness and stability of the double-row soft-pack battery cell stacking, and improving the quality of module stacking.
