Description

Technical Field

[0001] The present application relates to the technical field of batteries, and particularly to a slurry transfer device and a battery slurry preparation system. Background Art

[0002] The optimization and improvement of the battery slurry preparation process are considered to be the key ways to improve battery performance and reduce production costs. The battery slurry preparation involves multiple links, including mixing, grinding, stirring, coating, and drying, etc. Among these links, the slurry transfer device needs to maintain the performance of the slurry, and its role is crucial.

[0003] If the transportation time of the slurry transfer device is long, it will affect the performance of the transported slurry. Therefore, there is an urgent need for a slurry transfer device that can better maintain the slurry performance and quickly transport the slurry. Summary of the Utility Model

[0004] In view of the above problems, the present application provides a slurry transfer device and a battery slurry preparation system, which can improve the problem that the slurry performance is affected due to the long slurry transportation time.

[0005] In a first aspect, the present application provides a slurry transfer device for transferring battery slurry. The slurry transfer device includes a bracket, a storage member, and a conveying component. The bracket includes a bearing portion having an avoidance position; the storage member is arranged on the bearing portion and used for storing the slurry; the conveying component is installed on the bearing portion; wherein, the conveying component can be switched between a first state and a second state. When in the first state, the external slurry can be conveyed into the storage member through the conveying component; when in the second state, the slurry in the storage member can be conveyed to a collection point; the avoidance position is located below the bearing portion and allows an external trolley to enter and lift the bearing portion to realize the transportation of the slurry transfer device.

[0006] In the technical solution of the embodiment of the present application, an avoidance position is arranged on the bracket of the slurry transfer device to adapt to the AGV trolley, so as to transport the slurry transfer device to the next working station through the AGV trolley, thereby conveying the slurry in the slurry transfer device to the next working station, and accelerating the speed of conveying the slurry to the next working station. Moreover, the external slurry can be quickly conveyed into the storage member through the conveying component, or the slurry in the storage member can be output, improving the working efficiency of the slurry transfer device and shortening the time for conveying the same amount of external slurry into the storage member or outputting the slurry in the storage member.

[0007] In some embodiments, the conveying component includes a diaphragm pump and a pipeline. The diaphragm pump includes a suction port and a discharge port, and the suction port and the discharge port are detachably connected with the pipeline;

[0008] When in the first state, a pipeline is connected to the air inlet to suck external slurry, and a pipeline is connected between the air outlet and the storage member;

[0009] When in the second state, a pipeline is connected between the air outlet and the storage member, and a pipeline is connected to the air outlet to discharge the slurry in the storage member.

[0010] The above settings simplify the structure of the conveying component, facilitate the preparation of the conveying component, and simplify the switching method of the conveying component between different states.

[0011] In some embodiments, the storage member is provided with at least one feeding and discharging port, and the feeding and discharging port is detachably connected to the pipeline.

[0012] Because the connection between the feeding and discharging port and the pipeline is detachable, when the pipeline is blocked, the pipeline can be removed and replaced with a new one to maintain the conveying efficiency of the conveying component.

[0013] In some embodiments, the storage member has an accommodating cavity, and at least one feeding and discharging port is at the lowest point of the accommodating cavity.

[0014] Because the feeding and discharging port is located at the lowest point, the slurry in the accommodating cavity can flow to the feeding and discharging port under the action of its own gravity and flow out along the pipeline, reducing the probability of slurry accumulation in the accommodating cavity.

[0015] In some embodiments, the storage member is provided with a mating portion, the bearing portion is provided with a limiting member, the limiting member is detachably connected to the mating portion, and the storage member is limited.

[0016] After the storage member is placed on the bearing portion, the mating portion of the storage member can be connected to the limiting member on the bearing portion to limit the storage member. When transporting the slurry transfer equipment, the probability that the storage member moves under external impact and even falls from the bearing portion can be reduced, and the stability of the storage member during movement is improved.

[0017] In some embodiments, a first prompting portion protrudes from the limiting member. When the mating portion is connected to the limiting member, the orthographic projection of the second prompting portion of the mating portion falls within the first prompting portion.

[0018] In this way, by setting the prompting portion, the user is prompted whether the placement position of the storage member on the bearing portion is appropriate, so as to maximize the limiting effect of the limiting member.

[0019] In some embodiments, the extending direction of the limiting member is the same as the extending direction of the first prompting portion, the limiting member and the mating portion are slidably connected along the extending direction of the limiting member, and the first prompting portion is provided with a locking member, and the locking member connects the first prompting portion and the mating portion.

[0020] With the above settings, the limiting member guides the mating portion, which can accelerate the movement of the second prompting portion to the first prompting portion and improve the assembly speed between the limiting member and the mating portion.

[0021] In some embodiments, the slurry transfer device further includes a stirring member and an operating member. The stirring member is disposed in the accommodating cavity and stirs the slurry in the accommodating cavity. The operating member is disposed on the bearing portion, wherein the stirring member is controlled by the operating member.

[0022] In this way, a stirring member is equipped in the storage member to timely stir the slurry in the storage member by using the stirring member, reduce the precipitation of the slurry in the storage member, and make the viscosity and solid content of the slurry meet the requirements. The setting of the operating member simplifies the operation mode of the slurry transfer device and is convenient for the user to operate.

[0023] In some embodiments, the slurry transfer device further includes a portable power source. The portable power source is disposed on the bearing portion and provides power for the stirring member.

[0024] Because the above portable power source can continuously supply power to the stirring member and move together with the AGV cart under the drive of the bracket, the use flexibility and movement range of the slurry transfer device are broadened, and the movement range of the slurry transfer device will not be limited by the power supply method.

[0025] In some embodiments, a liquid level sensor is disposed in the accommodating cavity. The liquid level sensor is controlled by the operating member and is used to detect the liquid level in the accommodating cavity.

[0026] When there is slurry in the accommodating cavity of the storage member, the liquid level sensor can detect the liquid level of the slurry. The user can set the alarm liquid level of the liquid level sensor through the operating member to adapt to different types of slurry and storage members of different sizes, improve the use flexibility of the liquid level sensor, and the liquid level sensor can prompt the user of the liquid level in the accommodating cavity, which can reduce the probability of the phenomenon that the stirring member idles due to too low liquid level, and achieve energy saving of the slurry transfer device.

[0027] In some embodiments, the stirring member is rotatably disposed in the accommodating cavity around its own axis. There is a gap L between the end of the stirring member close to the inner wall of the accommodating cavity and the inner wall, and 80mm ≤ L ≤ 120mm.

[0028] In this way, when the stirring member rotates, it will not scrape the inner wall of the accommodating cavity, causing damage to the inner wall or the stirring member itself. It can not only protect the stirring member, but also fully stir the slurry in the accommodating cavity and improve the uniformity of the mixture of various components in the slurry.

[0029] In some embodiments, rollers are provided at the bottom of the storage member, and the rollers are in rolling connection with the bearing portion.

[0030] When the storage member is placed on the bearing portion or other supporting surfaces, the contact area between the storage member and the bearing portion is reduced, the resistance between the storage member and the bearing portion is decreased, and it is convenient to move the storage member.

[0031] In a second aspect, the present application provides a battery slurry preparation system, which includes a mixer, a coater, and the slurry transfer device in the above embodiments. The mixer is used for mixing the slurry, and the slurry transfer device is used for transporting the slurry stirred by the mixer to the coater.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0049] During the battery production process, the positive and negative active materials that play a major role in the electrochemical reaction of lithium-ion batteries are usually attached to similar thin current collectors in the form of thin pole sheets, forming the basic structural unit of lithium-ion batteries. The first step in manufacturing pole sheets is to make the active materials and other functional components into a completely plastic fluid (i.e. slurry), and then transport the prepared slurry to the target area through a slurry delivery system.

[0050] Battery slurry preparation involves multiple links, including mixing, grinding, stirring, coating and drying. The slurry transfer equipment serves as a transfer station for stirring and coating, and needs to maintain the stability of the slurry's physical properties such as viscosity, solid content and temperature for a long time. If the slurry transfer equipment transports the slurry for too long, the slurry's properties are prone to change, which will affect the effect of coating and thus affect the quality of the final product.

[0051] Based on the above considerations, to solve the technical problem of the time process of transporting slurry in the slurry transfer equipment. Some embodiments of the present application provide a slurry transfer equipment, which includes a bracket and a storage member. The storage member is installed on the bracket for storing slurry. The bracket can be used in conjunction with an Automated Guided Vehicle (AGV). The slurry transfer equipment is quickly transported between two adjacent workstations by the AGV cart.

[0052] The slurry transfer equipment disclosed in the embodiments of the present application is applied to a battery slurry preparation system or other systems that require the transportation of semi-fluid materials.

[0053] Please refer to Figure 1 , some embodiments of the present application provide a slurry transfer equipment 100 for transferring battery slurry. The slurry transfer equipment 100 includes a bracket 10 and a storage member 20. The bracket 10 includes a bearing portion 12 having an avoidance position 11; the storage member 20 is disposed on the bearing portion 12 and is used to store slurry; a conveying assembly 50 is installed on the bearing portion 12; wherein, the conveying assembly 50 can be switched between a first state and a second state. When in the first state, external slurry can be conveyed into the storage member 20 through the conveying assembly 50; when in the second state, the slurry in the storage member 20 can be conveyed to a collection point through the conveying assembly 50. The avoidance position 11 is located below the bearing portion 12 and allows an external cart to enter and lift the bearing portion 12 to achieve the transportation of the slurry transfer equipment 100.

[0054] Among them, the bearing portion 12 can divide the bracket 10 into upper and lower two-layer spaces. The lower space is a hollow portion and is configured as the avoidance position 11. The size of the avoidance position 11 can be adapted to an Automated Guided Vehicle (AGV), so that the AGV cart can enter the avoidance position 11 and act on the bearing portion 12 to transport the entire bracket 10. The bearing portion 12 is used to bear the storage member 20 and other components. The bearing surface of the bearing portion 12 is larger than the orthographic projection area of the storage member 20 on the bearing portion 12 to provide an installation space for other components.

[0055] The shape of the storage member 20 can be, but is not limited to, a barrel shape. The internal volume of the storage member 20 can be, but is not limited to, 100L to accommodate more slurry without affecting the bearing capacity of the AGV cart.

[0056] The conveying assembly 50 can be used to convey slurry, and can be, but is not limited to, components such as a peristaltic pump, a gear pump, and a centrifugal pump.

[0057] When it is necessary to transfer the slurry using the slurry transfer device 100, the conveying component 50 can be started, and the conveying component 50 can be used to convey the external slurry into the storage member 20. Subsequently, the AGV cart moves to the avoidance position 11. The AGV cart can support the bearing part 12, thereby lifting the entire bracket 10, so that the bracket 10 together with the storage member 20 can be moved to the next station. When the AGV cart drives the slurry transfer device 100 to move to the destination, the conveying component 50 can convey the slurry in the storage member 20 to the storage point of this station, so as to quickly realize the conveying of the slurry in the storage member 20.

[0058] In summary, an avoidance position 11 is provided on the bracket 10 of the slurry transfer device 100 to adapt to the AGV cart, so that the AGV cart can transport the slurry transfer device 100 to the next station, thereby conveying the slurry in the slurry transfer device 100 to the next station, which speeds up the speed of conveying the slurry to the next station. Moreover, the external slurry can be quickly conveyed into the storage member 20 or the slurry in the storage member 20 can be output through the conveying component 50, which improves the working efficiency of the slurry transfer device 100 and shortens the time for conveying the same amount of external slurry into the storage member 20 or outputting the slurry in the storage member 20.

[0059] As Figure 2 shown, in a specific embodiment, the height of the avoidance position 11 is 330 mm, so as to minimize the size of the avoidance position 11 on the premise of not affecting the entry of the AGV cart into the avoidance position 11, thereby reducing the size of the entire slurry transfer device 100 and reducing the difficulty of the AGV cart transporting the slurry transfer device 100.

[0060] It should be noted that the height of the avoidance position 11 is controlled within a suitable range to control the size of the slurry transfer device 100 and achieve a small-sized slurry transfer setting.

[0061] Please continue to refer to Figure 1 , in some embodiments, a plurality of support feet 121 protrude from the side of the bearing part 12 facing the avoidance position 11. The bearing part 12 is configured as a plate-like structure, and all the support feet 121 are arranged at intervals around the edge of the bearing part 12. All the support feet 121 together enclose the avoidance position 11. Along the length direction of the bearing part 12, the distance between two adjacent support feet 121 can be 880 mm. Along the width direction of the bearing part 12, the distance between two adjacent support feet 121 can be 670 mm.

[0062] As Figure 3 and Figure 4As shown, in some embodiments, the conveying assembly 50 includes a diaphragm pump 51 and a pipeline 52. The diaphragm pump 51 includes a suction port 511 and a discharge port 512, and the suction port 511 and the discharge port 512 are detachably connected to the pipeline 52. When in the first state, a pipeline 52 is connected to the suction port 511 to suck external slurry, and a pipeline 52 is connected between the discharge port 512 and the storage member 20. When in the second state, a pipeline 52 is connected between the discharge port 512 and the storage member 20, and a pipeline 52 is connected to the discharge port 512 to discharge the slurry in the storage member 20.

[0063] The diaphragm pump 51 realizes fluid conveyance through the periodic deformation of the diaphragm. The diaphragm pump 51 can be driven by a driving method such as pneumatic drive, mechanical drive, and hydraulic drive.

[0064] Such as Figure 4 As shown, the discharge port 512 and the suction port 511 on the diaphragm pump 51 are arranged on the same side and distributed from top to bottom. Both the discharge port 512 and the suction port 511 are equipped with a pipeline 52. When it is necessary to convey the external slurry into the storage member 20, the conveying assembly 50 is in the first state, the pipeline 52 communicated with the suction port 511 is communicated with the container for storing the external slurry, and the pipeline 52 communicated with the discharge port 512 is communicated with the storage member 20. Starting the diaphragm pump 51, the external slurry can be quickly conveyed into the storage member 20.

[0065] When the slurry transfer device 100 is transported to the designated position, the conveying assembly 50 is switched from the first state to the second state, the pipeline 52 communicated with the suction port 511 is communicated with the storage member 20, and the pipeline 52 communicated with the discharge port 512 is communicated with the storage container at the designated position. Starting the diaphragm pump 51, the slurry in the storage member 20 can be quickly conveyed to the storage container at the designated position.

[0066] The above settings simplify the structure of the conveying assembly 50, facilitate the preparation of the conveying assembly 50, and simplify the switching method of the conveying assembly 50 between different states.

[0067] In some embodiments, the storage member 20 is provided with at least one inlet / outlet 23, and the inlet / outlet 23 is detachably connected to the pipeline 52.

[0068] For example, in an example, the storage member 20 is provided with an inlet / outlet 23, and the inlet / outlet 23 is arranged at the top, bottom or other positions of the storage member 20. When the conveying assembly 50 is in different states, the pipeline 52 communicated with the suction port 511 or the discharge port 512 is connected to the inlet / outlet 23, and the connection method between the inlet / outlet 23 and the pipeline 52 can be but is not limited to snap connection and threaded connection.

[0069] In another example, two inlets and outlets 23 are provided on the storage member 20, one of the inlets and outlets 23 is located at the top of the storage member 20, and the other inlet and outlet 23 is located at the bottom of the storage member 20. The two inlets and outlets 23 can be selectively communicated with the suction port 511 or the discharge port 512 through the pipeline 52.

[0070] As the use time of the conveying assembly 50 increases, it is easy for the slurry to accumulate on the inner wall of the pipeline 52. Since the connection between the inlet and outlet 23 and the pipeline 52 is a detachable connection method, when the pipeline 52 is blocked, the pipeline 52 can be removed and replaced with a new pipeline 52 to maintain the conveying efficiency of the conveying assembly 50.

[0071] Furthermore, as Figure 3 shown, in some embodiments, the storage member 20 has a receiving cavity 21, and at least one inlet and outlet 23 is at the lowest point of the receiving cavity 21.

[0072] When the conveying assembly 50 is in the second state, the pipeline 52 communicated with the suction port 511 is communicated with the inlet and outlet 23 at the lowest point, and the pipeline 52 communicated with the discharge port 512 is communicated with the storage container at a specified position. The diaphragm pump 51 is started. Since the inlet and outlet 23 is at the lowest point, the slurry in the receiving cavity 21 can flow to the inlet and outlet 23 under the action of its own gravity and flow out along the pipeline 52, reducing the probability of slurry accumulation in the receiving cavity 21.

[0073] It should be noted that in the process of inputting external slurry into the storage member 20, it is also possible not to rely on the conveying assembly 50. For example, workers can pour the slurry into the storage member 20 manually using a bucket.

[0074] As Figure 1 shown, in some embodiments, the storage member 20 is provided with a mating portion 24, and the bearing portion 12 is provided with a limiting member 122. The limiting member 122 is detachably connected to the mating portion 24 to limit the storage member 20.

[0075] The mating portion 24 can protrude from the outer wall of the storage member 20. The connection method between the limiting member 122 and the mating portion 24 can be, but is not limited to, threaded connection and snap connection. The number of the mating portions 24 is equal to the number of the limiting members 122, and there is a one-to-one correspondence between them.

[0076] After the storage member 20 is placed on the bearing portion 12, the mating portion 24 of the storage member 20 can be connected to the limiting member 122 on the bearing portion 12, and then the storage member 20 can be limited. When transporting the slurry transfer device 100, the probability that the storage member 20 moves due to external impact and even falls from the bearing portion 12 can be reduced, and the stability of the storage member 20 during movement is improved.

[0077] Please continue to refer toFigure 1 , specifically, in some embodiments, a first prompting portion 1221 protrudes from the limiting member 122. When the engaging portion 24 is connected to the limiting member 122, the orthographic projection of the second prompting portion 241 of the engaging portion 24 falls within the first prompting portion 1221.

[0078] For example, three bumps are provided on the engaging portion 24, and these three bumps are configured as the second prompting portion 241. A strip-shaped plate protrudes from the limiting member 122. When the orthographic projections of all the bumps fall within the strip-shaped plate, it means that the storage member 20 has moved to a preset position on the bearing portion 12, and the limiting member 122 and the engaging portion 24 can be connected together to limit the storage member 20.

[0079] In this way, by providing the prompting portion, the user is prompted whether the placement position of the storage member 20 on the bearing portion 12 is appropriate, so as to maximize the limiting effect of the limiting member 122.

[0080] More specifically, in some embodiments, the extending direction of the limiting member 122 is the same as that of the first prompting portion 1221. The limiting member 122 and the engaging portion 24 are slidably connected along the extending direction of the limiting member 122. A locking member is provided on the first prompting portion 1221, and the locking member connects the first prompting portion 1221 and the engaging portion 24.

[0081] Exemplarily, a fence is provided at the edge of the bearing portion 12, and the fence is configured as the limiting member 122. A strip-shaped first prompting portion 1221 protrudes from the fence, and the extending direction of the first prompting portion 1221 is the same as that of the fence. When installing the limiting member 122 and the engaging portion 24, the engaging portion 24 can be brought into contact with the fence and moved along the fence until the second prompting portion 241 of the engaging portion 24 completely falls within the first prompting portion 1221, and then the first prompting portion 1221 and the engaging portion 24 can be connected together by using a locking member (such as a bolt).

[0082] With the above arrangement, the limiting member 122 is used to guide the engaging portion 24, which can accelerate the speed of the second prompting portion 241 moving to the first prompting portion 1221 and improve the assembly speed between the limiting member 122 and the engaging portion 24.

[0083] Please refer to Figure 1 and Figure 5 , in some embodiments, the slurry transfer device 100 further includes a stirring member 30 and an operating member 60. The stirring member 30 is disposed in the accommodating cavity 21 and stirs the slurry in the accommodating cavity 21. The operating member 60 is disposed on the bearing portion 12, wherein the stirring member 30 is controlled by the operating member 60.

[0084] The stirring member 30 may include a double propeller blade, a single propeller blade, a variable pitch propeller, etc. The motor power equipped for the stirring member 30 may be 6W, and its rotation speed range is 0 rpm to 1200 rpm. When there is slurry placed in the storage member 20, the stirring member 30 can continuously operate to agitate the slurry. If the slurry stands still for a long time, the slurry in the storage member 20 is likely to solidify and produce gel precipitation, and in this way, the viscosity and solid content of the transferred slurry will increase. Using slurry with a high viscosity in the subsequent coating process will affect the dimensional deviation of the coating process and the quality of the battery.

[0085] The operating member 60 may have a touch function. For example, the operating member 60 includes a touch display screen, and the user controls the stirring member 30 to perform corresponding operations through the touch display screen, such as adjusting the rotation speed of the stirring member 30, starting and stopping the stirring member 30.

[0086] In this way, the stirring member 30 is equipped in the storage member 20 to use the stirring member 30 to timely agitate the slurry in the storage member 20, reduce the precipitation of the slurry in the storage member 20, and make the viscosity and solid content of the slurry meet the requirements. And setting the operating member 60 simplifies the operation mode of the slurry transfer device 100 and is convenient for the user to operate.

[0087] As Figure 1 shown, in some embodiments, the slurry transfer device 100 further includes a portable power source 40. The portable power source 40 is arranged on the bearing portion 12 and provides power for the stirring member 30.

[0088] The portable power source 40 may include an Uninterruptible Power Supply (UPS). A UPS is an uninterruptible power supply containing an energy storage device, and it is mainly used to provide uninterrupted power for some devices with high requirements for power stability. The battery capacity of the portable power source 40 is 48V, 60Ah. In one embodiment, the size of the portable power source 40 is 280mm * 200mm * 170mm.

[0089] The portable power source 40 can be installed on the bearing portion 12 by a detachable method such as clamping. When the portable power source 40 is damaged, it can be timely removed from the bearing portion 12, and a new portable power source 40 can be installed on the bearing portion 12. In addition, when the power stored in the portable power source 40 is used up, the portable power source 40 can be removed and charged for continued use.

[0090] Because the above-mentioned portable power source 40 can always supply power to the stirring member 30 and move together with the AGV cart under the drive of the bracket 10, the flexibility of use and the movement range of the slurry transfer device 100 are broadened, and the movement range of the slurry transfer device 100 will not be limited by the power supply method.

[0091] In other embodiments, the operating member 60 and the portable power source 40 can be integrated into one unit, reducing the installation components of the slurry transfer device 100 and shortening the assembly time of the slurry transfer device 100.

[0092] As Figure 1 shown, in some embodiments, a liquid level sensor 70 is provided in the accommodation cavity 21. The liquid level sensor 70 is controlled by the operating member 60 and is used to detect the liquid level in the accommodation cavity 21.

[0093] When there is slurry in the accommodation cavity 21 of the storage member 20, the liquid level sensor 70 can detect the liquid level of the slurry. The user can set the alarm liquid level of the liquid level sensor 70 through the operating member 60 to adapt to different types of slurries and different sizes of the storage member 20, improving the flexibility of use of the liquid level sensor 70. Moreover, the liquid level sensor 70 can prompt the user of the liquid level in the accommodation cavity 21, reducing the probability of the stirring member 30 idling due to too low a liquid level, and achieving energy conservation of the slurry transfer device 100.

[0094] Please refer to Figure 5 , in some embodiments, the stirring member 30 is rotatably disposed in the accommodation cavity 21 about its own axis. There is a gap L between the end of the stirring member 30 close to the inner wall of the accommodation cavity 21 and the inner wall, where 80 mm ≤ L ≤ 120 mm.

[0095] The gap between the end of the stirring member 30 close to the inner wall of the accommodation cavity 21 and the inner wall can be understood as the distance between the edge of the paddle and the inner wall of the accommodation cavity 21. That is, the stirring member 30 does not contact the inner wall of the accommodation cavity 21 when rotating. The specific value of the gap L can be 80 mm, 90 mm, 100 mm, 110 mm, 120 mm, and any value between two adjacent values.

[0096] In this way, the stirring member 30 does not scrape the inner wall of the accommodation cavity 21 when rotating, causing damage to the inner wall or the stirring member 30 itself. This not only protects the stirring member 30 but also can fully stir the slurry in the accommodation cavity 21, improving the uniformity of the mixture of various components in the slurry.

[0097] More specifically, as Figure 5 shown, in some embodiments, rollers 22 are provided at the bottom of the storage member 20, and the rollers 22 are in rolling connection with the bearing portion 12.

[0098] When the storage member 20 is placed on the bearing portion 12 or other supporting surfaces, the contact area between the storage member 20 and the bearing portion 12, etc. is reduced, and the resistance between the storage member 20 and the bearing portion 12 is reduced, facilitating the movement of the storage member 20.

[0099] In addition, some embodiments of the present application further provide a battery slurry preparation system, which includes a mixer, a coater, and the slurry transfer device 100 in the above embodiments. The mixer is used to mix the slurry, and the slurry transfer device 100 is used to transport the slurry stirred by the mixer to the coater.

[0100] In the initial stage of slurry preparation, the required powder materials, additives, and solvents are added to the mixer. The mixer performs operations such as turning, shearing, kneading, and dispersing, so that the powder materials and solvents are fully mixed and fused, thereby obtaining a slurry that meets the requirements. Subsequently, the obtained slurry is transported to the slurry transfer device 100, and then the slurry transfer device 100 is transported to the coater by an AGV cart to perform the coating operation.

[0101] When using the AGV cart to equip the slurry transfer device 100 to transport the slurry, the slurry can be transported quickly. Moreover, during the transportation process, the slurry transfer device 100 can continuously stir the transported slurry to ensure the quality of the slurry.

[0102] Specifically, in one embodiment, as Figure 1 and Figure 5 shown, the slurry transfer device 100 includes a bracket 10, a storage member 20, a stirring member 30, a portable power source 40, a conveying assembly 50, and an operating member 60. The bracket 10 includes an avoidance position 11 and a bearing portion 12. The bearing portion 12 can divide the bracket 10 into upper and lower space layers. The lower space layer is a hollow portion and is configured as the avoidance position 11. The size of the avoidance position 11 is adapted to the AGV cart, so that the AGV cart can enter the avoidance position 11. The storage member 20, the stirring member 30, the portable power source 40, the conveying assembly 50, and the operating member 60 are all installed on the bearing portion 12. The portable power source 40 can supply power to the stirring member 30, the conveying assembly 50, and the operating member 60.

[0103] During actual use, when the storage member 20 stores the slurry, the stirring member 30 can continuously stir the slurry in the storage member 20 to reduce the precipitation of the slurry in the storage member 20, so that the viscosity and solid content of the slurry meet the requirements. The user can control the stirring member 30 to perform corresponding operations through the touch display screen, such as adjusting the rotation speed of the stirring member 30, starting and stopping the stirring member 30.

[0104] When the slurry transfer device 100 is transported to the coating station by the AGV cart, the stirring member 30 stops operating, and the slurry in the storage member 20 is transported to the coating station by the conveying assembly 50. In this way, on the basis of maintaining the performance of the slurry in the storage member 20, the speed of transporting the slurry to the next station is accelerated.

[0105] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0106] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
