[0014] In some embodiments, the stirring device further comprises a pump assembly, a first pipe and a second pipe, and the tank body is provided with an inlet and an outlet connected to the stirring chamber;

[0026] In some embodiments, the stirring device further comprises a flow meter, which is disposed on the second pipe and located on a side close to the pump assembly, and is used to detect a flow rate flowing through the pump assembly.

[0027] Through the above structure, when the material flows in the circulation path outside the stirring chamber, the flow rate of the material flowing through the pump assembly can be detected in real time by the flow meter, so as to monitor whether the pump assembly is blocked and ensure the smooth and safe circulation process.

[0028] In some embodiments, the stirring device further comprises an alarm connected to the flow meter, the alarm being configured to receive a flow signal from the flow meter and to activate an alarm when the flow signal is zero.

[0029] When the flow meter detects that the material flow is zero, it means that the homogenizing pump is blocked or there is no material in the mixing chamber. At this time, the alarm can be activated in time and send out an alarm signal, which is convenient for the operator to deal with it in time, avoid idling of the homogenizing pump, and improve the overall safety of the mixing device.

[0030] In some embodiments, the vibration mechanism includes an ultrasonic generator disposed at the bottom of the stirring chamber, and the ultrasonic generator is used to convert electrical energy into mechanical vibration and act on the material.

[0042] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0043] A battery cell is the smallest unit that makes up a battery. A battery cell usually includes an end cap, a housing, an electrode assembly, and other functional components. The electrode assembly is the component in the battery cell where electrochemical reactions occur. The electrode assembly is mainly formed by winding or stacking positive and negative electrode sheets, and a separator is usually provided between the positive and negative electrode sheets. The parts of the positive and negative electrode sheets with active materials constitute the main body of the electrode assembly, and the parts of the positive and negative electrode sheets without active materials each constitute the pole ears.

[0044] The positive electrode sheet or the negative electrode sheet is formed by coating a slurry on a current collector, that is, the portion of the current collector coated with the slurry is the portion of the positive electrode sheet or the negative electrode sheet having active material, and the portion of the current collector not coated with the slurry is the portion of the positive electrode sheet or the negative electrode sheet not having active material. In other words, the active material on the electrode sheet refers to the slurry.

[0045] Since the composition of the slurry is complex, it is necessary to uniformly mix various materials to obtain it. Based on this, in the production process of the battery, it is necessary to use a batching system to process and batch various materials to obtain a coatable slurry.

[0046] However, the current slurry is prone to crystallization or precipitation due to insufficient mixing of various materials during the batching process, resulting in low uniformity of the slurry, which in turn affects the performance of the final electrode.

[0047] Based on the above considerations, in order to solve the problem that crystallization or precipitation is prone to occur during the current batching process, resulting in low uniformity of the slurry, a stirring device is provided in one or more embodiments of the present application. When the material is contained in a stirring chamber for mixing, the vibration mechanism can form mechanical vibration and act on the material, thereby reducing the probability of material agglomeration. At the same time, the material is stirred by the stirring component, and the stirring component is controlled to move at a uniform speed while stirring, thereby reducing the probability of fixed vortex sedimentation formed during the stirring process, so that the material in the stirring chamber can be evenly mixed to form a slurry, thereby improving the uniformity of the slurry.

[0048] See also Figure 1 An embodiment of the present application provides a stirring device 100, comprising a tank body 10, a vibration mechanism 20 and a stirring assembly 30. The tank body 10 has a stirring chamber 11 for containing materials. The vibration mechanism 20 is disposed on the tank body 10 and is used to drive the materials to vibrate. The stirring assembly 30 is movably disposed on the tank body 10, a portion of the stirring assembly 30 extends into the stirring chamber 11, and is configured to perform a stirring operation on the materials.

[0049] It should be noted that the stirring chamber 11 refers to a structure that can provide a space for holding materials and stir and mix the materials in the space. The materials held in the stirring chamber 11 can be various auxiliary materials used to mix and form active material slurry coated on the current collector, or various materials used to mix and form other slurries.

[0050] The vibration mechanism 20 refers to a structure that can provide mechanical vibration and act on the material in the stirring chamber 11. The vibration mechanism 20 is set on the tank body 10, and the material in the stirring chamber 11 is driven to vibrate by the vibration mechanism 20, which can reduce the probability of material agglomeration and is conducive to stirring the material.

[0051] Furthermore, the stirring assembly 30 refers to a component for stirring the material in the stirring chamber 11. The stirring assembly 30 is movably disposed on the tank body 10, and can be moved in a horizontal direction, a vertical direction, or a specific path, and of course, can also be moved in both the horizontal and vertical directions.

[0052] Specifically, when the stirring assembly 30 is located at a fixed position for stirring, it is easy for the material to form a fixed vortex sedimentation. Therefore, the stirring assembly 30 in the present application is movably arranged on the tank body 10, so that the stirring assembly 30 can move at a constant speed relative to the tank body 10 while performing the stirring operation, for example, move horizontally at a constant speed, thereby reducing the probability of the material forming a fixed vortex sedimentation and making the material mixing more uniform.

[0053] Therefore, through the above structure, when the material is contained in the stirring chamber 11 for mixing, the vibration mechanism 20 can form mechanical vibration and act on the material, thereby reducing the probability of material agglomeration. At the same time, the material is stirred by the stirring component 30, and the stirring component 30 is controlled to move at a uniform speed during stirring, thereby reducing the probability of fixed vortex sedimentation being formed during the stirring process, so that the material in the stirring chamber 11 can be evenly mixed to form a slurry, thereby improving the uniformity of the slurry.

[0054] In some embodiments, the stirring device 100 further includes a first driving member 40 disposed on the tank body 10 . The first driving member 40 is drivingly connected to the stirring assembly 30 and is used to drive the stirring assembly 30 to move at a constant speed along a preset direction.

[0055] It should be noted that the preset direction can be set to a horizontal direction, a vertical direction, or a specific path, such as a circular path, and the stirring component 30 moves at a uniform speed along the circular path under the driving action of the first driving member 40.

[0056] Specifically, the first driving member 40 may include a driving motor and a movable guide rail. The movable guide rail is horizontally arranged on the tank body 10, and the stirring assembly 30 is connected to the movable guide rail. The driving motor drives the stirring assembly 30 to move at a uniform speed horizontally on the movable guide rail.

[0057] Furthermore, the first driving member 40 may also include a ball screw, which is arranged on the tank body 10 in the horizontal direction, and the stirring assembly 30 is arranged on the ball screw, so as to drive the stirring assembly 30 to move at a constant speed in the horizontal direction. Of course, the first driving member 40 may also include other driving structures to drive the stirring assembly 30 to move at a constant speed in the horizontal direction, which will not be described in detail here.

[0058] In addition, the first driving member 40 may further include a moving cylinder, and the stirring assembly 30 is disposed on the moving cylinder. The moving cylinder can drive the stirring assembly 30 to move at a uniform speed along the vertical direction.

[0059] By setting the first driving member 40, the stirring component 30 can move at a constant speed in a preset direction under the action of the first driving member 40 during the rotational stirring process, so that the stirring component 30 can stir synchronously and move at a constant speed, stir the materials at different positions in the stirring chamber 11, and improve the uniformity of the stirring operation.

[0060] In some embodiments, the stirring assembly 30 includes a second driving member 31 and a stirring paddle 32 that are connected in a driving manner. The second driving member 31 is used to drive the stirring paddle 32 to rotate, and at least a portion of the stirring paddle 32 extends into the stirring chamber 11 to perform a stirring operation. The second driving member 31 is connected in a driving manner to the first driving member 40.

[0061] Specifically, the second driving member 31 may include a stirring motor, which is drivingly connected to the stirring paddle 32 and drives the stirring paddle 32 to rotate, thereby stirring the material in the stirring chamber 11 .

[0062] Furthermore, the stirring motor is drivingly connected to the first driving member 40 , that is, the stirring motor is driven by the first driving member 40 to move at a uniform speed in the horizontal direction, thereby driving the stirring paddle 32 to move synchronously in the horizontal direction to uniformly stir the materials at different positions in the stirring chamber 11 .

[0063] Through the above structure, while the stirring paddle 32 performs a stirring operation on the material, the stirring paddle 32 can be driven by the first driving member 40 to move at a constant speed along a preset direction, thereby realizing synchronous rotation and lateral movement of the stirring paddle 32 and reducing the probability of the material forming a fixed vortex and settling.

[0064] In some embodiments, the stirring device 100 further includes a pump assembly 50, a first pipe 60 and a second pipe 70, and the tank body 10 is provided with an inlet and an outlet connected to the stirring chamber 11. The first pipe 60 is connected between the outlet and the pump assembly 50, and the second pipe 70 is connected between the inlet and the pump assembly 50. The pump assembly 50 is used to drive the material to flow between the first pipe 60 and the second pipe 70 in the stirring chamber 11.

[0065] Specifically, the feed port is communicated with the stirring chamber 11, and materials can be transported into the stirring chamber 11 through the feed port. The discharge port is communicated with the stirring chamber 11, and the mixed materials in the stirring chamber 11 can be transported out of the stirring chamber 11 through the discharge port.

[0066] One end of the first pipe 60 is connected to the discharge port, and the other end is connected to the inlet of the pump assembly 50. One end of the second pipe 70 is connected to the outlet of the pump assembly 50, and the other end is connected to the feed port. Thus, a circulation path is formed among the stirring chamber 11, the first pipe 60, the pump assembly 50 and the second pipe 70.

[0067] Further, the pump assembly 50 refers to a component that can provide power for the material to make the material flow in the circulation path. That is, the pump assembly 50 provides power to make the material in the stirring chamber 11 flow through the first pipe 60, the pump assembly 50 and the second pipe 70 in sequence, and finally return to the stirring chamber 11.

[0068] Through the above structure, an external circulation is formed outside the stirring chamber 11, and the materials in the stirring chamber 11 are mixed more evenly by means of the external circulation.

[0069] In some embodiments, the discharge port is opened at the bottom of the tank body 10 , and the inlet port is opened at the top of the tank body 10 .

[0070] Specifically, driven by the power of the pump assembly 50 , the material at the bottom of the stirring chamber 11 flows into the first pipe 60 from the discharge port, passes through the pump assembly 50 , enters the second pipe 70 , and then enters the stirring chamber 11 from the bottom of the stirring chamber 11 through the second pipe 70 .

[0071] Thus, the material in the stirring chamber 11 flows out from the bottom and flows in from the top, so that all the materials in the stirring chamber 11 can be uniformly mixed.

[0072] In some embodiments, the pump assembly 50 includes a homogenizing pump disposed between the first pipe 60 and the second pipe 70 .

[0073] It should be noted that the material being stirred usually contains some granular substances, and the sizes of the granular substances are different. Some larger particles may affect the coating uniformity of the slurry on the current collector.

[0074] In addition, when the material is stirred, some bubbles will be formed in the material, and the formed bubbles will also affect the coating uniformity of the slurry on the current collector.

[0075] Therefore, by setting up a homogenizing pump, on the basis of providing circulation power for the material, the particles and bubbles in the material can also be dispersed and sheared to achieve homogenization of the material and further improve the uniformity of the material.

[0076] In some embodiments, the stirring device 100 further includes a feed pipe 80 and a discharge pipe 90, wherein the discharge end of the feed pipe 80 is connected to the second pipe 70, and the feed end of the discharge pipe 90 is connected to the second pipe 70. The feed pipe 80 is provided with a first control valve 12 for controlling the on-off of the feed pipe 80, and the discharge pipe 90 is provided with a second control valve 13 for controlling the on-off of the discharge pipe 90.

[0077] Specifically, the discharge end of the feed pipe 80 is connected to the second pipe 70, and the material is put in from the other end of the feed pipe 80 opposite to the discharge end, passes through the feed pipe 80 and the second pipe 70, and enters the stirring chamber 11 from the feed port. The feed end of the discharge pipe 90 is connected to the second pipe 70, and the stirred material in the stirring chamber 11 enters the second pipe 70 from the discharge port, and then enters the discharge pipe 90 from the second pipe 70, and is discharged from the discharge pipe 90.

[0078] Through the above structure, the first pipe 60 and the second pipe 70 realize the circulation flow of materials outside the stirring chamber 11, and cooperate with the feed pipe 80 and the discharge pipe 90 to realize the feeding and discharging of the stirring chamber 11, and smoothly realize the entire mixing and batching process of the materials.

[0079] In some embodiments, the stirring device 100 also includes a third control valve 14 and a fourth control valve 15. The third control valve 14 is arranged on the first pipeline 60 and is used to control the on-off of the first pipeline 60. The fourth control valve 15 is arranged on the second pipeline 70 and is located on the side of the second pipeline 70 close to the feed port. The fourth control valve 15 is used to control the on-off of the second pipeline 70.

[0080] Specifically, the third control valve 14 can control the opening and closing of the first pipeline 60 , and the fourth control valve 15 can control the opening and closing of the second pipeline 70 .

[0081] In actual use, first open the first control valve 12 and the fourth control valve 15, and close the second control valve 13 and the third control valve 14. At this time, the feed pipe 80 and the first pipe 60 are in a connected state, and the discharge pipe 90 and the second pipe 70 are respectively in a disconnected state.

[0082] The material is transported into the stirring chamber 11 through the feed pipe 80 and the first pipe 60. At the same time, the vibration mechanism 20 is turned on to apply mechanical vibration to the material to prevent the material from agglomerating. After the material is injected, the first control valve 12 is closed, the third control valve 14 is opened, and the homogenizing pump is turned on. At this time, a circulation pipeline is formed between the stirring chamber 11, the first pipe 60, the homogenizing pump and the second pipe 70. When the material passes through the homogenizing pump, the homogenizing pump can disperse and shear the particles and bubbles in the material to achieve homogenization of the material.

[0083] Furthermore, the first driving member 40 and the second driving member 31 are turned on, the second driving member 31 drives the stirring paddle 32 to rotate, and the first driving member 40 drives the second driving member 31 and the stirring paddle 32 to move at a uniform speed in the horizontal direction, thereby realizing synchronous rotation and lateral movement to uniformly stir the material in the stirring chamber 11.

[0084] When the material is stirred, the fourth control valve 15 is closed and the second control valve 13 is opened. At this time, the stirred material flows into the first pipeline 60 , then flows into the discharge pipeline 90 through the homogenizing pump and the second pipeline 70 , and then flows out from the discharge pipeline 90 .

[0085] Therefore, through the above structure, the on-off control between the first pipeline 60, the second pipeline 70, the feed pipeline 80 and the discharge pipeline 90 can be achieved, so as to control the feeding, discharging and circulation flow of materials and facilitate operation.

[0086] In some embodiments, the stirring device 100 further includes a control component 16, which is respectively connected to the first control valve 12, the second control valve 13, the third control valve 14 and the fourth control valve 15 for controlling their opening and closing.

[0087] Specifically, the control component 16 may include a controller (e.g., a PLC) and a human-machine interface control screen (e.g., an HMI control screen). The operator may input corresponding parameters required for the ingredients through the HMI control screen, such as the water injection volume, the rotation speed of the agitator 32, the operating time of the homogenizing pump, and the discharge time, etc., so as to better control the agitator 100.

[0088] The controller can control the opening and closing of the first control valve 12 , the second control valve 13 , the third control valve 14 and the fourth control valve 15 , and flexibly control the operation process of the stirring device 100 .

[0089] Through the above structure, the stirring device 100 can be controlled more flexibly, and the operation is convenient and quick.

[0090] In some embodiments, the stirring device 100 further includes a flow meter 17 , which is disposed on the second pipe 70 and located on a side close to the pump assembly 50 . The flow meter 17 is used to detect the flow rate flowing through the pump assembly 50 .

[0091] Specifically, when the material flows in the circulation path outside the stirring chamber 11, the flow rate of the material flowing through the homogenizing pump can be detected in real time by the flow meter 17, so as to monitor whether the homogenizing pump is blocked and ensure the smooth and safe circulation process.

[0092] In some embodiments, the stirring device 100 further includes an alarm (not shown in the figure) connected to the flow meter 17, and the alarm is used to receive a flow signal from the flow meter 17 and activate an alarm when the flow signal is zero.

[0093] When the flow meter 17 detects that the flow rate of the material is zero, it means that the homogenizing pump is blocked or there is no material in the stirring chamber 11. At this time, the alarm can be activated in time and send out an alarm signal, which is convenient for the operator to deal with it in time, avoid idling of the homogenizing pump, and improve the overall safety of the stirring device 100.

[0094] In some embodiments, the vibration mechanism 20 includes an ultrasonic generator 21 disposed at the bottom of the stirring chamber 11 , and the ultrasonic generator 21 is used to convert electrical energy into mechanical vibration and act on the material.

[0095] By providing the ultrasonic generator 21, electrical energy can be converted into mechanical vibration and act on the material, thereby reducing the probability of material agglomeration and making the material mixing more uniform.

[0096] Based on the same concept as the above-mentioned stirring device 100, the present application also provides a batching system, including the stirring device 100 as described above, and the stirring device 100 is used to accommodate materials to be batched and stir the materials.

[0097] According to one or more embodiments, when the present application is in use, firstly, various parameters corresponding to the required ingredients are input through the HMI control screen. After the input is completed, the PLC controls the opening of the first control valve 12 and the fourth control valve 15, and the closing of the second control valve 13 and the third control valve 14, and water or other materials are injected into the stirring chamber 11 through the feed pipe 80.

[0098] After the injection of the material is completed according to the set value, the first control valve 12 is closed and the third control valve 14 is opened. At the same time, the ultrasonic generator 21, the stirring motor and the first driving member 40 are turned on, the stirring motor drives the stirring paddle 32 to rotate, and the first driving member 40 drives the stirring motor and the stirring paddle 32 to move at a uniform speed in the horizontal direction, so that the material in the stirring chamber 11 is uniformly stirred.

[0099] Furthermore, the homogenizing pump is turned on, so that the material in the stirring chamber 11 passes through the first pipeline 60 , the homogenizing pump and the second pipeline 70 in sequence, and then returns to the stirring chamber 11 , forming a circulation path outside the stirring chamber 11 .

[0100] After the predetermined time, the batching is completed, the PLC controls to close the fourth control valve 15, and opens the second control valve 13, and the homogenizing pump starts the discharging mode. When the flow meter 17 detects that the flow signal is zero, it means that the discharging is completed, and the homogenizing pump is closed at this time.

[0101] At this time, the first control valve 12 is opened again to replenish water into the stirring chamber 11, and the first control valve 12 is closed after the water replenishment is completed. The homogenizing pump is controlled to start the self-circulation mode, which can clean the stirring chamber 11 and the pipeline. After the cleaning is completed, the homogenizing pump starts the discharging mode again until the flow meter 17 detects that the flow signal is zero, which means that the entire batching and cleaning process is completed.

[0102] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
