Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electric core production equipment, especially relates to a kind of electric core stacking forming device and battery production system. BACKGROUND

[0002] The electric core module is stacked and combined by multiple electric core monomers, and currently, the electric core stacking into module and the shaping and pressure maintaining of the module after stacking are indispensable links in the module production process.The existing automatic production line basically stacks the electric core into module in separate work station, and then shapes and pressure maintains the module in the next work station after stacking, to ensure the flatness and fixed length of the module in each direction after stacking, so as to ensure that the size and flatness of the module after stacking meet the design requirements.However, the resources and space occupied by the two work stations are relatively large, and the cost of production line equipment is high.

[0003] In addition, since the electric core is first pre-tightened in the stacking station after stacking, and then flows to the shaping and pressure maintaining station for size shaping and pressure maintaining adjustment, the electric core stacking process is prone to form a 0.5mm-1mm misalignment in the stacking direction due to the thin and long nature of the blade battery, and the misalignment will lead to virtual welding and collapse during subsequent BSB welding without correction.However, since the electric core and the adhesive cotton or PUR glue between the electric cores are bonded during the stacking process, the adhesive cotton and PUR glue have been effective for a period of time when the entire module is shaped and pressure maintained at this time, and it is difficult to adjust the misalignment of the electric core, which requires a large amount of transverse pressure and pressure maintaining time, reduces the production efficiency, and increases the running time of the work station, affecting the production line rhythm.

[0031] The battery cell stacking and forming apparatus provided in this application includes a support, a first pressing mechanism, and a second pressing mechanism. The support is provided with a support plate, which supports a battery cell assembly, which includes at least two individual battery cells. The first pressing mechanism is located at at least one end of the support plate in a first direction and is used to press and align the battery cell assembly in the first direction. The second pressing mechanism is located on both sides of the support plate and is used to press and align the battery cell assembly laterally and to press and hold it vertically. The vertical, lateral, and first directions are mutually perpendicular. By pressing the battery cell assembly in the first direction using the first pressing mechanism, at least two individual battery cells are aligned and stacked in the first direction. Then, the second pressing mechanism presses and aligns the battery cell assembly laterally to complete the stacking of the battery cell assembly, ensuring the stacking accuracy. The second pressing mechanism then presses and holds the battery cell assembly vertically to ensure that the adhesive between the individual battery cells is cured and tightly connected. This allows the battery cell stacking and shaping pressing functions to be completed in one station, reducing production line equipment costs and floor space, ensuring production line cycle time, and improving production efficiency.

[0032] like Figures 1 to 3 As shown, one embodiment of this application provides a battery cell stacking and forming apparatus, including a support 110, a first pressing mechanism 120, and a second pressing mechanism 130;

[0033] The bracket 110 is provided with a support plate 111, which is used to support the battery cell assembly 200, which includes at least two individual battery cells.

[0034] The first pressing mechanism 120 is disposed at at least one end of the bearing plate 111 in the first direction L1, and is used to press and align the battery cell assembly 200 in the first direction L1.

[0035] The second clamping mechanism 130 is disposed on both sides of the bearing plate 111 and is used to clamp and align the battery cell assembly 200 in the horizontal direction L3 and clamp and hold pressure in the vertical direction L2. The vertical direction L2, the horizontal direction L3 and the first direction L1 are perpendicular to each other.

[0036] The cell pack 200 consists of at least two individual cells, each of which is a blade battery. The blade battery is in the shape of a thin sheet or a relatively thin plate. Multiple blade batteries are stacked together and bonded together with adhesive cotton or PUR adhesive to form the cell pack 200.

[0037] The support 110 is provided with a support plate 111, and the battery cells are placed on the support plate 111. For example, multiple battery cells are moved to the support plate 111 by a conveyor belt or a robot. At this time, at least two battery cells are stacked and aligned in the first direction L1 by the first pressing mechanism 120.

[0038] In practice, for ease of understanding, the first direction L1 is denoted as L1, such as... Figure 1 As shown. A stop 112 may be provided on the support plate 111. When at least two battery cells are placed on the support plate 111, the first pressing mechanism 120 moves along the first direction L1 toward the stop 112, so that the first pressing mechanism 120 and the stop 112 work together to press against at least two battery cells, so that at least two battery cells are pressed and aligned in the first direction L1.

[0039] As one possible implementation, two first pressing mechanisms 120 may be provided along the first direction L1, and the two first pressing mechanisms 120 may move toward each other. That is, when at least two battery cells are placed on the support plate 111, the two first pressing mechanisms 120 move toward each other, so that the two first pressing mechanisms 120 work together to press against at least two battery cells, so that at least two battery cells are aligned in the first direction L1.

[0040] In one possible implementation, a stop 112 may be provided on the support plate 111, and two first pressing mechanisms 120 may be provided along the first direction L1, with the support plate 111 located between the two first pressing mechanisms 120, which can move towards each other. That is, when at least two battery cells are placed on the support plate 111 and located on one side of the support plate 111, the first pressing mechanism 120 on one side of the support plate 111 moves toward the support plate 111, thereby the first pressing mechanism 120 and the stop 112 work together to press against at least two battery cells, causing the at least two battery cells to be pressed and aligned in the first direction L1. Similarly, when at least two battery cells are placed on the support plate 111 and located on the other side of the support plate 111, the first pressing mechanism 120 on the other side of the support plate 111 moves toward the support plate 111, thereby the first pressing mechanism 120 and the stop 112 work together to press against at least two battery cells, causing the at least two battery cells to be pressed and aligned in the first direction L1.

[0041] In some possible embodiments, only one of the two first clamping mechanisms 120 may move. For example, when at least two battery cells are placed on the carrier plate 111, the first first clamping mechanism 120 remains stationary, while the second first clamping mechanism 120 moves toward the first first clamping mechanism 120, so that at least two battery cells are aligned in the first direction L1 under the action of the two first clamping mechanisms 120.

[0042] After the battery cell assembly 200 is pressed and aligned by the first pressing mechanism 120, the second pressing mechanism 130 performs horizontal L3 pressing and alignment and vertical L2 pressing, shaping, and pressure holding on the battery cell assembly 200. The vertical L2 direction is denoted as L2, and the horizontal L3 direction is denoted as L3. Figure 1 As shown. The first direction L1, the horizontal direction L3, and the vertical direction L2 are mutually perpendicular. For example, the first direction L1, the horizontal direction L3, and the vertical direction L2 can be regarded as the X, Y, and Z axes in world coordinates, respectively.

[0043] In implementation, the first pressing mechanism 120 first stacks and aligns at least two individual cells of the cell assembly 200 in the first direction L1. Then, the second pressing mechanism 130 presses the cell assembly 200 laterally L3, achieving alignment of at least two individual cells in the lateral direction L3. At this point, at least two individual cells of the cell assembly 200 are aligned along the stacking direction, meaning that the projections of at least two individual cells on the carrier plate 111 completely or substantially completely overlap. Then, the second pressing mechanism 130 presses and holds the pressure vertically L2 on the cell assembly 200 to compress the individual cells, making the adhesive bonding between the individual cells more stable and reliable, thus ensuring product quality.

[0044] The battery cell stacking and forming apparatus provided in this application includes a support 110, a first pressing mechanism 120, and a second pressing mechanism 130. The support 110 is provided with a support plate 111, which is used to support a battery cell assembly 200, which includes at least two individual battery cells. The first pressing mechanism 120 is provided at at least one end of the support plate 111 in the first direction L1, and is used to press and align the battery cell assembly 200 in the first direction L1. The second pressing mechanism 130 is provided on both sides of the support plate 111, and is used to press and align the battery cell assembly 200 in the horizontal direction L3 and press and hold it in the vertical direction L2. The vertical direction L2, the horizontal direction L3, and the first direction L1 are perpendicular to each other. The first pressing mechanism 120 presses the battery cell assembly 200 in the first direction L1, so that at least two individual battery cells are aligned and stacked in the first direction L1. Then, the second pressing mechanism 130 presses the battery cell assembly 200 in the lateral direction L3 to complete the stacking of the battery cell assembly 200, ensuring the stacking accuracy of the battery cells. The second pressing mechanism 130 then presses the battery cell assembly 200 in the vertical direction L2 to maintain pressure, so that the glue between the individual battery cells is cured and tightly connected. This allows the battery cell stacking and shaping pressure maintenance functions to be completed in one station, reducing the production line equipment cost and floor space, ensuring the production line cycle time, and improving production efficiency.

[0045] Furthermore, the second clamping mechanism 130 includes a transverse L3 clamping member 131, a vertical L2 pressure holding member 132, a first driving member 133, and a second driving member 134;

[0046] The first driving member 133 is disposed on the bracket 110 and connected to the transverse L3 pressing member 131, and is used to drive the transverse L3 pressing member 131 to move along the transverse L3 direction, so that the transverse L3 pressing member 131 performs transverse L3 centering pressing on the battery cell group 200.

[0047] The second driving member 134 is mounted on the bracket 110 and connected to the vertical L2 pressure holding member 132. It is used to drive the vertical L2 pressure holding member 132 to move along the vertical L2 direction so that the vertical L2 pressure holding member 132 can vertically press and hold the pressure on the cell assembly 200.

[0048] During implementation, the horizontal L3 clamping member 131 is responsible for horizontally centering and clamping the battery cell group 200 to achieve the stacking and alignment of the battery cell group 200, while the vertical L2 pressure holding member 132 is responsible for vertically clamping and holding the pressure of the battery cell group 200 to ensure the stable and reliable connection of the battery cell group 200.

[0049] In practice, the first driving component 133 and the second driving component 134 may include any one of a motor, a cylinder, and a lead screw assembly, without limitation.

[0050] Furthermore, the battery cell stacking and forming apparatus provided in this application also includes a servo axis mechanism 140 disposed on the support 110. The servo axis mechanism 140 is connected to the second pressing mechanism 130 and is used to drive the second pressing mechanism 130 to move along the first direction L1.

[0051] In implementation, the support plate 111 is generally elongated to support multiple battery cell groups 200. The second clamping mechanism 130 needs to move along the first direction L1. For example, when the first battery cell group 200 is placed in the first position on the support plate 111, the first clamping mechanism 120 clamps the first battery cell group 200 in the first direction L1. The servo axis mechanism 140 drives the lateral L3 pressure holding member of the second clamping mechanism 130 to move to the first position, and then the first drive member 133 drives the lateral L3 pressure holding member to extend, clamping the first battery cell group 200 laterally L3. Subsequently, the servo axis mechanism 140 drives the second clamping mechanism 130 to move forward, and the vertical L2 pressure holding member 132 moves to the first position, clamping and holding the stacked first battery cell group 200 laterally L3 and vertically L2.

[0052] When the second battery cell assembly 200 is placed on the support plate 111 at the second position, which is adjacent to the first position, the first clamping mechanism 120 clamps the second battery cell assembly 200 in the first direction L1. At this time, the first and second battery cell assemblies 200 are stacked in the first direction L1. The servo axis mechanism 140 drives the lateral L3 pressure holding member to move to the second position, and then the first drive member 133 drives the lateral L3 pressure holding member to extend, clamping the second battery cell assembly 200 in the lateral L3 alignment. Subsequently, the servo axis mechanism 140 drives the second clamping mechanism 130 to move forward, and the vertical L2 pressure holding member 132 moves to the second position, clamping and holding the stacked second battery cell assembly 200 in both the lateral L3 and vertical L2 directions.

[0053] This process is repeated cyclically, with the previous group of 200 cells stacked in the center and the next group of 200 cells immediately shaped and held under pressure, continuously moving forward in a stacking manner to improve production efficiency.

[0054] Furthermore, the battery cell stacking and forming apparatus provided in this application also includes a rangefinder 150, which is disposed at one end of the second pressing mechanism 130 near the first pressing mechanism 120, and is used to measure the position of the battery cell group 200 that has completed lateral L3 pressing and alignment.

[0055] In implementation, the end of the second clamping mechanism 130 closest to the first clamping mechanism 120 can be considered the front side of the second clamping mechanism 130, and similarly, the end of the second clamping mechanism 130 furthest from the first clamping mechanism 120 can be considered the rear side of the second clamping mechanism 130. In other words, the rangefinder 150, the horizontal L3 clamping member 131, and the vertical L2 pressure holding member 132 are arranged sequentially from the side closest to the first clamping mechanism 120 to the side furthest from the first clamping mechanism 120.

[0056] When a group of battery cells 200 is placed in a first position on the carrier plate 111, for example, the battery cell stacking and forming apparatus provided in this application also includes a robot (not shown in the figure) for gripping the battery cell group 200 to place the battery cell group 200 on the carrier plate 111.

[0057] The first pressing mechanism 120 presses the previous group of battery cells 200 in the first direction L1. For example, the first pressing mechanism 120 includes a first pressing member 121 and a third driving member 122. The third driving member 122 is disposed on the bracket 110. The first pressing member 121 is connected to the third driving member 122 and is used to move along the first direction L1 under the drive of the third driving member 122 to press the battery cell group 200 in the first direction L1.

[0058] Then, the servo axis mechanism 140 drives the lateral L3 pressure-holding member of the second clamping mechanism 130 to move to the first position, and the first drive member 133 drives the lateral L3 pressure-holding member to extend, performing lateral L3 centering and clamping on the previous group of battery cells 200. Subsequently, the servo axis mechanism 140 drives the second clamping mechanism 130 to move forward, and the vertical L2 pressure-holding member 132 moves to the first position, performing lateral L3 and vertical L2 clamping and pressure holding on the stacked previous group of battery cells 200.

[0059] The rangefinder 150 measures the position of the previous group of battery cells 200 to confirm the stacking and pressing position of the next group of battery cells 200. In other words, the rangefinder 150 measures the position of the previous group of battery cells 200 to confirm the second position.

[0060] The next battery cell group 200 is placed on the support plate 111 at a second position adjacent to the first position. The first clamping mechanism 120 clamps the next battery cell group 200 in the first direction L1. At this time, the previous and next battery cell groups 200 are stacked in the first direction L1. The servo axis mechanism 140 drives the lateral L3 pressure holding member to move to the second position, and then the first drive member 133 drives the lateral L3 pressure holding member to extend, clamping the next battery cell group 200 in the lateral L3 alignment. Subsequently, the servo axis mechanism 140 drives the second clamping mechanism 130 to move forward, and the vertical L2 pressure holding member 132 moves to the second position, clamping and holding the stacked next battery cell group 200 in both the lateral L3 and vertical L2 directions.

[0061] This process is repeated cyclically, with the previous group of 200 cells stacked in the center and the next group of 200 cells immediately shaped and held under pressure, continuously moving forward in a stacking manner to improve production efficiency.

[0062] Furthermore, to make distance measurement more accurate, the battery cell stacking and forming apparatus provided in this application also includes a telescopic member 160 disposed at one end of the second pressing mechanism 130 near the first pressing mechanism 120. The telescopic member 160 is connected to the rangefinder 150 and is used to drive the rangefinder 150 to move in the lateral direction L3.

[0063] In practice, the current group of battery cells 200 is placed at a first position on the support plate 111, and the first clamping mechanism 120 clamps the previous group of battery cells 200 in the first direction L1. Then, the servo axis mechanism 140 drives the lateral L3 pressure-holding member of the second clamping mechanism 130 to move to the first position, and the first drive member 133 drives the lateral L3 pressure-holding member to extend, clamping the previous group of battery cells 200 in the lateral L3 alignment. Subsequently, the servo axis mechanism 140 drives the second clamping mechanism 130 to move forward, and the vertical L2 pressure-holding member 132 moves to the first position, clamping and holding the stacked previous group of battery cells 200 in both the lateral L3 and vertical L2 directions.

[0064] The telescopic component 160 drives the rangefinder 150 to extend, so that the rangefinder 150 measures the position of the previous group of battery cells 200 to confirm the stacking and pressing position of the next group of battery cells 200. In other words, the rangefinder 150 measures the position of the previous group of battery cells 200 to confirm the second position.

[0065] The next battery cell group 200 is placed on the support plate 111 at a second position adjacent to the first position. The first clamping mechanism 120 clamps the next battery cell group 200 in the first direction L1. At this time, the previous and next battery cell groups 200 are stacked in the first direction L1. The servo axis mechanism 140 drives the lateral L3 pressure holding member to move to the second position, and then the first drive member 133 drives the lateral L3 pressure holding member to extend, clamping the next battery cell group 200 in the lateral L3 alignment. Subsequently, the servo axis mechanism 140 drives the second clamping mechanism 130 to move forward, and the vertical L2 pressure holding member 132 moves to the second position, clamping and holding the stacked next battery cell group 200 in both the lateral L3 and vertical L2 directions.

[0066] This process is repeated cyclically, with the previous group of 200 cells stacked in the center and the next group of 200 cells immediately shaped and held under pressure, continuously moving forward in a stacking manner to improve production efficiency.

[0067] It should be noted that the battery cell stacking and forming device provided in this application is equipped with a processor. The rangefinder 150 measures the position information of the previous group of battery cells 200 and outputs this position information to the processor. The processor calculates the second position information and controls the first pressing mechanism 120, the second pressing mechanism 130, the servo axis mechanism 140, and the telescopic component 160 to work together, which will not be described in detail. Optionally, the processor can be a 51 series microcontroller, an STM32 series microcontroller, or other types of microcontrollers, as long as they can achieve the above functions, without limitation.

[0068] Furthermore, the battery cell stacking and forming apparatus provided in this application also includes a lifting and positioning mechanism disposed on the support 110. The lifting and positioning mechanism is connected to the support plate 111 and is used to drive the support plate 111 to move in the vertical direction L2.

[0069] During implementation, when the battery cell assembly 200 is placed on the support plate 111, the lifting and positioning mechanism can drive the support plate 111 to rise and fall to a specific height and be positioned so that the first pressing mechanism 120 and the second pressing mechanism 130 can better act on the battery cell assembly 200 to stack, align and maintain pressure on the battery cell assembly 200.

[0070] Secondly, this application also provides a battery production system, including the cell stacking and forming apparatus as described above.

[0071] The battery cell stacking and forming apparatus provided in this application includes a support 110, a first pressing mechanism 120, and a second pressing mechanism 130. The support 110 is provided with a support plate 111, which is used to support a battery cell assembly 200, which includes at least two individual battery cells. The first pressing mechanism 120 is provided at at least one end of the support plate 111 in the first direction L1, and is used to press and align the battery cell assembly 200 in the first direction L1. The second pressing mechanism 130 is provided on both sides of the support plate 111, and is used to press and align the battery cell assembly 200 in the horizontal direction L3 and press and hold it in the vertical direction L2. The vertical direction L2, the horizontal direction L3, and the first direction L1 are perpendicular to each other. The first pressing mechanism 120 presses the battery cell assembly 200 in the first direction L1, so that at least two individual battery cells are aligned and stacked in the first direction L1. Then, the second pressing mechanism 130 presses the battery cell assembly 200 in the lateral direction L3 to complete the stacking of the battery cell assembly 200, ensuring the stacking accuracy of the battery cells. The second pressing mechanism 130 then presses the battery cell assembly 200 in the vertical direction L2 to maintain pressure, so that the glue between the individual battery cells is cured and tightly connected. This allows the battery cell stacking and shaping pressure maintenance functions to be completed in one station, reducing the production line equipment cost and floor space, ensuring the production line cycle time, and improving production efficiency.
