[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] Combined with Figure 1 To Attachment Figure 3 As shown, the present invention provides a lithium battery homogenization and slurrying dual process control method, comprising at least one metering tank, a premixing tank, a homogenizer, a first circulation tank and a second circulation tank, the method comprising: S100: Obtain a first work order and a second work order, and the metering tank mixes the first powder material according to the first work order and transports the first powder material to the premixing tank.

[0023] For example, in the first work order, the first powder material requires 5 kg each of powder A, powder B, powder C and powder D. Four metering tanks 1 are used to weigh out 5 kg of powder A, powder B, powder C and powder D respectively, and 5 kg of powder A, powder B, powder C and powder D are transported to the premixing tank 2.

[0024] S200: Confirm that the premixing time of the first powder is not less than the first set time, the premixing tank conveys the first powder to the homogenizer, the metering tank mixes the second powder according to the second work order, and conveys the second powder to the premixing tank.

[0025] For example, the first set time is 1 hour, and the premixing time of the first powder in the premixing tank 2 exceeds 1 hour, which means that the first powder has been fully premixed and can be transported to the homogenizer 3 for the next step of processing. After the first powder is transported from the premixing tank 2 to the homogenizer 3, the premixing tank 2 is idle and can be used to process the second work order. In the second work order, the ratio of powder A and powder B is 4 kg each, and the ratio of powder C and powder D is 6 kg each. Then, the metering tank 1 weighs 4 kg of powder A and 4 kg of powder D. Powder B, 6 kg of powder C, and 6 kg of powder D are transported to the premixing tank 2 for premixing, so that the homogenizer 3 processes the first powder while the premixing tank 2 processes the second powder at the same time. As a result, when the homogenizer 3 completes the processing of the first powder, the powder of the second work order can enter the homogenizer 3 for processing immediately, and there is no need to wait for the premixing of the powder on the second work order, thereby saving time and improving work efficiency; and also preventing high-speed homogenizing and dispersing equipment from idling for a long time.

[0026] S300: Confirm that the dispersion time of the first powder by the homogenizer is not less than the second set time, the homogenizer conveys the mixed first powder to the first circulation tank, confirm that the premixing time of the second powder is not less than the first set time, and the premixing tank conveys the second powder to the homogenizer.

[0027] For example, the second set time is 2 hours. After the first powder is dispersed at high speed for 2 hours, the first powder that has completed high-speed dispersion is transported to the second circulation tank 5 for separate dispersion. At this time, the homogenizer 3 is idle. Since the premixing tank 2 is premixing the second powder in the second work order while the homogenizer 3 is dispersing the first powder of the first work order at high speed, the second powder premixed in the premixing tank 2 can be directly transported to the homogenizer 3 at this time. There is no need to wait for the metering tank 1 to proportion the second powder and the premixing tank 2 to premix the second powder, which saves the premixing time of the second powder and greatly improves the production efficiency.

[0028] S400: Confirm that the dispersion time of the second powder by the homogenizer is not less than the second set time, and the homogenizer conveys the mixed second powder to the second circulation tank.

[0029] Confirming that the dispersion time of the second powder by the homogenizer 3 is not less than the second set time is conducive to ensuring the sufficient mixing of the second powder, and conveying the mixed second powder to the second circulation tank 5, so that the first circulation tank 4 and the second circulation tank 5 do not interfere with each other, and the slurry of the first work order and the slurry of the second work order are completed separately.

[0030] In the first work order, the first work order is used to proportion the type and amount of the first powder, the metering tank 1 is used to weigh the powder, so as to ensure that the proportion of the first powder complies with the first work order and the quality of the first powder is ensured, the premixing tank 2 will be used to premix the first powder; confirm that the first powder is premixed in the premixing tank 2 for a set time, so as to ensure that the mixing degree of the first powder meets the standard and improve the quality of the first powder, the homogenizer 3 is used to disperse the first powder at high speed, and confirm that the dispersion time of the first powder by the homogenizer 3 is not less than the second set time, which is conducive to ensuring that the first powder is fully stirred. When the homogenizer 3 disperses the first powder in the first work order at high speed, the metering tank 1 is used to weigh the second powder in the second work order, and the second powder is transported to the premixing tank 2 for premixing, so as to achieve the high-speed dispersion of the first powder by the homogenizer 3. While dispersing, the second powder is premixed by the premixing tank 2 to realize dual-thread control of the operation of two work orders, thereby saving a lot of time; after confirming that the dispersion time of the first powder by the homogenizer 3 reaches the set value, the processed first powder is transported to the first circulation tank 4, and after high-speed dispersion to meet the process indicators, the slurry is transported to the second circulation tank 5; the homogenizer 3 and the first circulation tank 4 then execute the second work order, so that the homogenizer 3 can perform high-speed dispersion processing on the second powder in the second work order, avoiding the idleness of the homogenizer 3, thereby saving a lot of processing time and improving production efficiency; after the homogenizer 3 completes the high-speed dispersion processing of the second powder, the slurry in the second circulation tank 5 can be transported to the finished product tank, and the slurry of the second work order in the first circulation tank 4 can be transported to the second circulation tank 5 for separate dispersion again, thereby improving production efficiency. Compared with the existing production system, the present invention only adds a second circulation tank 5, but can shorten the entire production cycle by about half (according to the prior art, it takes about 3-4 hours to complete two work orders respectively, while the present application only takes 90-100 minutes).

[0031] In some other possible implementations, the first circulation tank 4 and the second circulation tank 5 may be connected to the homogenizer 3, respectively, so that after the homogenization process is completed, they can be dispersed independently in the two circulation tanks. A connecting pipe may also be provided between the first circulation tank 4 and the second circulation tank 5, so that the above-mentioned high-speed dispersion process of the second work order by the homogenizer 3 and the first circulation tank 4 can be achieved, and the dispersed slurry can be continuously dispersed at a high speed in the second circulation tank 5.

[0032] Continue to combine Figure 4As shown, in some embodiments, the lithium battery homogenization equipment also includes a host computer and a programmable logic controller, the host computer is connected to the programmable logic controller, and the programmable logic controller is connected to the metering tank, the premixing tank, the homogenizer, the first circulation tank and the second circulation tank.

[0033] The programmable logic controller is used to control the operation of the metering tank, the premixing tank, the homogenizer, the first circulation tank and the second circulation tank. The host computer is used to download the first work order and the second work order, control the ratio of the metering tank to the first powder and the second powder according to the first work order and the second work order, and control the operation of the metering tank, the premixing tank, the homogenizer, the first circulation tank and the second circulation tank through the programmable logic controller according to the first work order and the second work order.

[0036] For example, the database in the MES system stores the types of powders in the metering tank and the corresponding quantities of the powders. When the MES obtains the first and second work orders issued, and provides the first and second work orders to the host computer for downloading, the types and quantities of the powders required for the first and second work orders can be obtained, and compared with the metering tank to determine whether the type and quantity of the powders in the metering tank are sufficient to complete the first and second work orders. If the type and quantity of the powders in the first metering tank are sufficient to complete the first and second work orders, the first and second work orders are provided through the MES system. The upper computer is provided with download, and an instruction to confirm the operation of the first work order and the second work order is issued. The upper computer downloads the first work order and the second work order from the MES system, and controls the operation of the lithium battery homogenization equipment through the programmable logic controller according to the first work order and the second work order. At the same time, after the powder materials of the first work order and the second work order are proportioned through the metering tank, the database of the MES system updates the amount of the powder materials in the metering tank; if the type and amount of the powder materials in the first metering tank are not enough to complete the first work order and the second work order, the metering tank is replaced and connected to the premixing tank, or the amount of the powder materials in the metering tank is supplemented.

[0037] In some embodiments, after the second circulation tank disperses the mixed second powder, the dual-process control method for lithium battery slurrying further includes: the MES system acquires process flow information and prints the process flow information.

[0038] Printing the process flow is conducive to the subsequent tracing of the production process of the first powder and the second powder, such as printing the number, start time, and end time of the work order being produced, and storing the process flow information of the work order in the database within the MES system.
