Description

[0002] In the lithium battery industry, the battery cell usually needs to be made by a powder system. For the powder system, the most important thing is to adjust the delivery accuracy of the powder system, that is, the difference between the preset powder demand weight value and the actual delivery weight value of the powder after the powder system completes the delivery of each batch of powder. The size of the delivery accuracy will affect the subsequent battery cell manufacturing process. Maintaining the delivery accuracy at a small level can make the delivered powder more accurate. Generally speaking, the delivery parameters will affect the delivery accuracy. By adjusting the delivery parameters of the powder system and controlling the powder system to operate according to the adjusted delivery parameters, the delivery accuracy of the powder system can be adjusted.

[0048] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application and are not all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, every other embodiment obtained by a person skilled in the art without creative work belongs to the scope of protection of the present application.

[0049] In the prior art, the conveying parameters of the next conveying batch are manually adjusted according to the size relationship between the conveying precision of the present conveying batch and the target precision. For example, when the conveying precision of any conveying batch does not meet the requirements, the conveying parameters of the next conveying batch are manually adjusted to make the conveying precision of the next conveying batch reach the target precision. However, the manual adjustment of the conveying parameters has a large error and low adjustment efficiency.

[0050] Based on this, the control method for the conveying precision of the powder system provided by the embodiments of the present application compares the conveying precision of each conveying batch with the target precision range corresponding to the conveying batch, and automatically adjusts the conveying parameters corresponding to the next conveying batch according to the comparison result, thereby reducing the precision error and improving the adjustment efficiency, compared with the manual adjustment method in the prior art.

[0051] Please refer to Figure 1 , Figure 1 The flowchart of the method for adjusting the conveying parameters of the battery powder system provided by the embodiments of the present application is shown.

[0052] As shown in Figure 1 The method for adjusting the conveying parameters of the battery powder system provided by the embodiments of the present application includes the following steps:

[0053] S100, for each conveying batch in a target batch group, the target powder system is controlled to convey the powder of the conveying batch according to the conveying parameters corresponding to the conveying batch;

[0054] Here, the number of the conveying batches included in the target batch group is set according to the actual situation, for example, the number of the conveying batches included in the target batch group can be 100.

[0055] Here, the conveying parameters can include the conveying speed in the low-speed conveying mode of the powder system and the valve closing time of the powder system.

[0056] In an actual application scenario, each conveying batch includes multiple conveying modes, and a corresponding conveying speed is preset for each conveying mode. For any conveying batch, when the conveying batch is in any conveying mode of the multiple conveying modes, the powder system conveys powder at the conveying speed corresponding to the conveying mode. The conveying modes can include a high-speed conveying mode, a low-speed conveying mode, and a point-motion conveying mode, wherein the preset conveying speed in the high-speed conveying mode, the preset conveying speed in the low-speed conveying mode, and the preset conveying speed in the point-motion conveying mode decrease in turn.

[0057] Specifically, for each conveying batch, the powder system first conveys the powder of the conveying batch using the high-speed conveying mode, at which time the powder system is in a high-speed conveying phase; when the cumulative conveying weight value of the powder reaches a first preset weight value, the powder system conveys the powder of the conveying batch using the low-speed conveying mode, at which time the powder system is in a low-speed conveying phase; when the cumulative conveying weight value of the powder reaches a second preset weight value, the powder system conveys the powder of the batch using the point-motion conveying mode, at which time the powder system is in a point-motion conveying phase.

[0058] Here, the valve closing time of the powder system is the time for each conveying batch from the opening of the master control valve to the closing of the master control valve. Here, the master control valve is a valve used to control the start and end of conveying of each conveying batch.

[0059] S200, for each conveying batch in the target batch group, acquiring a conveying accuracy of the target powder system conveying the powder of the conveying batch;

[0060] Here, the conveying accuracy of each conveying batch is the difference between the preset powder demand weight value corresponding to the conveying batch and the actual powder conveying weight value. The preset powder demand weight value is determined according to actual conditions, and in specific implementation, the preset powder demand weight value can be the same or different for each conveying batch. The actual powder conveying weight value is the cumulative conveying weight value of the powder after the target powder system has conveyed the powder of the conveying batch.

[0061] In fact, due to the influence of conveying parameters, the conveying accuracy determined by the target powder system for different conveying parameters is also different. Therefore, by setting different conveying parameters for each conveying batch, the conveying accuracy of the target powder system can be continuously adjusted.

[0062] S300, comparing the conveying accuracy of the conveying batch with the target accuracy range corresponding to the conveying batch, and adjusting the conveying parameter corresponding to the next conveying batch according to the comparison result.

[0063] As an example, the step S300 can include steps S310-S330:

[0064] S310, determine whether the conveying precision of the conveying batch is located within the first target precision range corresponding to the conveying batch;

[0065] Here, each conveying batch corresponds to a first target precision range. The first target precision range corresponding to each conveying batch is obtained based on the preset powder demand weight value corresponding to the conveying batch and a preset error. Here, the preset error is determined according to actual conditions, for example, the preset error can be ±2‰.

[0066] Specifically, for each conveying batch, the product of the preset powder demand weight value of the conveying batch and the positive value of the preset error is determined as the upper limit value of the first target precision range, and the product of the preset powder demand weight value of the conveying batch and the negative value of the preset error is determined as the lower limit value of the first target precision range.

[0067] For example, in the case of a preset error of ±2‰, assuming that the preset powder demand weight value is 100g, then the product of the preset powder demand weight value and the positive value of the preset error "2‰" "0.2" can be determined as the upper limit value of the first target precision range, and the product of the preset powder demand weight value and the negative value of the preset error "-2‰" "-0.2" can be determined as the lower limit value of the first target precision range. That is, in this case, the first target precision range is [-0.2, +0.2].

[0068] S320, if located within the first target precision range, adjust the conveying parameters corresponding to the next conveying batch according to the batch number corresponding to the conveying batch;

[0069] As an example, in this step S320, steps S321-S323 can be included:

[0070] S321, if located within the first target precision range, determine whether the batch number corresponding to the conveying batch is any target batch number in the preset plurality of target batch numbers;

[0071] Here, the preset plurality of target batch numbers includes the Mxnth batch number; wherein M is the first batch number in the preset plurality of target batch numbers, n is a positive integer greater than zero, and Mxnis less than or equal to the number of conveying batches included in the target batch group.

[0072] For example, when the number of conveying batches included in the target batch group is 100, the target batch group includes 100 batch numbers, which are batch number 1, batch number 2, …, batch number 100. When M is batch number 10, the preset plurality of target batch numbers includes batch number 10, batch number 20, …, batch number 100 in turn.

[0073] S322, if the batch number corresponding to the conveying batch is not any target batch number, determining the conveying parameter corresponding to the conveying batch as the conveying parameter corresponding to the next conveying batch;

[0074] S323, if the batch number corresponding to the conveying batch is any target batch number, adjusting the conveying parameter corresponding to the next conveying batch based on the size relationship between the preset powder demand weight value and the powder actual conveying weight value corresponding to each of the plurality of predetermined conveying batches before the conveying batch.

[0075] In the case that the conveying parameter includes the conveying speed in the low-speed conveying mode of the powder system and the valve closing time of the powder system, in relation to step S323, in specific implementation, can include:

[0076] Firstly, in step S3231, for each of the plurality of predetermined conveying batches before the conveying batch, compare the size of the preset powder demand weight value and the powder actual conveying weight value corresponding to the predetermined conveying batch; if for each predetermined conveying batch, the preset powder demand weight value corresponding to the predetermined conveying batch is greater than the powder actual conveying weight value corresponding to the predetermined conveying batch, in step S3232, the sum of the valve closing time corresponding to the conveying batch and the preset valve closing delay value is determined as the new valve closing time, and the sum of the conveying speed corresponding to the conveying batch and the preset acceleration value is determined as the new conveying speed; if for each predetermined conveying batch, the preset powder demand weight value corresponding to the predetermined conveying batch is not greater than the powder actual conveying weight value corresponding to the predetermined conveying batch, in step S3233, the difference between the valve closing time corresponding to the conveying batch and the preset valve closing advance value is determined as the new valve closing time, and the difference between the conveying speed corresponding to the conveying batch and the preset deceleration value is determined as the new conveying speed.

[0077] Here, the number and batch number of the predetermined conveying batch are determined according to the actual situation, in specific implementation, the number and batch number of the plurality of predetermined conveying batches before the conveying batch can be set according to the size of the conveying number of the conveying batch, the larger the batch number of the conveying batch, the more the number of the plurality of predetermined conveying batches before the conveying batch. For example, when the batch number of the conveying batch is 10, the batch number of the predetermined conveying batch can be 3, 6 and 9, when the batch number of the conveying batch is 20, the batch number of the predetermined conveying batch can be 3, 6, 9, 12, 15 and 18.

[0078] Here, the preset acceleration value and the preset deceleration value are set according to actual conditions. In specific implementation, the preset acceleration value can be the same or different for each batch of powder delivery, and the preset deceleration value can be the same or different. For example, in the case of different preset acceleration values, the technician can set them in the controller before the target powder system delivers each batch of powder.

[0079] For example, the preset acceleration value can be 1 rpm, the preset valve closing delay value can be 1 s, the preset deceleration value can be 1 rpm, and the preset valve closing advance value can be 1 s. However, the above delivery parameters are only exemplary, and those skilled in the art can adaptively adjust the delivery parameters according to actual conditions, which is not limited in the present application.

[0080] Through step S3232, the valve closing time in the corresponding delivery parameter of the next batch of delivery can be adjusted to be longer, and the delivery speed in the corresponding delivery parameter of the next batch of delivery can be adjusted to be faster, so that the powder delivered by the next batch of delivery is more through this adjustment method, thereby approaching the preset powder demand weight value. Through step S3233, the valve closing time in the corresponding delivery parameter of the next batch of delivery can be adjusted to be shorter, and the delivery speed in the corresponding delivery parameter of the next batch of delivery can be adjusted to be slower, so that the powder delivered by the next batch of delivery is less through this adjustment method, thereby approaching the preset powder demand weight value.

[0081] At the same time, by determining whether the batch number corresponding to the batch of delivery is any target batch number, if it is any target batch number, the subsequent corresponding processing is performed in this way, the powder system can be calibrated regularly, so as to ensure the delivery accuracy.

[0082] S330, if not located in the first target accuracy range, comparing the delivery accuracy with a second target accuracy range, and adjusting the delivery parameter corresponding to the next batch of delivery according to the comparison result;

[0083] Here, the second target accuracy range is greater than the first target accuracy range. For example, in the case of the first target accuracy range being [-0.2, +0.2], the second target accuracy range can be [-0.5, +0.5].

[0084] For example, this step S330 can include steps S331-S333:

[0085] S331, if not located in the first target accuracy range, determining whether the delivery accuracy is located in the second target accuracy range;

[0086] S332, if located in the second target accuracy range, determining a new delivery parameter according to the delivery accuracy, and determining the new delivery parameter as the delivery parameter corresponding to the next batch of delivery;

[0087] In the case where the conveying parameters include the conveying speed in the low-speed conveying mode of the powder system and the valve closing time of the powder system, in relation to step S332, in specific implementation, the following can be included:

[0088] If located in the second target accuracy range, the size relationship between the conveying accuracy and the upper and lower limit values of the first target accuracy range is determined at step S3321; if the conveying accuracy is greater than the upper limit value of the first target accuracy range, the difference between the conveying speed corresponding to the current conveying batch and the preset deceleration value is determined as the new conveying speed at step S3322, and the difference between the valve closing time corresponding to the current conveying batch and the preset valve closing advance value is determined as the new valve closing time; if the conveying accuracy is less than the lower limit value of the first target accuracy range, the sum of the conveying speed corresponding to the current conveying batch and the preset acceleration value is determined as the new conveying speed at step S3323, and the sum of the valve closing time corresponding to the current conveying batch and the preset valve closing delay value is determined as the new valve closing time.

[0089] Through step S3322, the valve closing time in the corresponding conveying parameters in the next conveying batch can be shortened, and the conveying speed in the corresponding conveying parameters in the next conveying batch can be slowed down, so that the powder conveyed in the next conveying batch is less through this adjustment mode, so as to approach the preset powder demand weight value. Through step S3323, the valve closing time in the corresponding conveying parameters in the next conveying batch can be lengthened, and the conveying speed in the corresponding conveying parameters in the next conveying batch can be accelerated, so that the powder conveyed in the next conveying batch is more through this adjustment mode, so as to approach the preset powder demand weight value.

[0090] S333, if not located in the second target accuracy range, determining that the battery powder system is faulty.

[0091] Here, if not located in the second target accuracy range, it means that the battery powder system is faulty, at this time, the purpose of adjusting the conveying accuracy cannot be achieved by adjusting the conveying parameters, and manual intervention can be performed subsequently to check the powder system.

[0092] In addition, the adjustment method further includes:

[0093] Starting from the first conveying batch in the plurality of conveying batches included in the target batch group, it is detected whether the conveying accuracy of each target conveying batch in the preset continuous number of target conveying batches is not located in the first target accuracy range corresponding to the target conveying batch; if the conveying accuracy of each target conveying batch in the preset continuous number of target conveying batches is not located in the first target accuracy range corresponding to the target conveying batch, it is determined that the battery powder system is faulty.

[0094] Here, the preset continuous quantity is set according to actual conditions, for example, the preset continuous quantity can be 3.

[0095] In the following, a method for adjusting a battery powder system conveying parameter provided by an embodiment of the present application will be introduced in combination with a specific application scenario.

[0096] Figure 2 A flow chart of a method for adjusting a battery powder system conveying parameter provided by another exemplary embodiment of the present application is shown.

[0097] As shown in Figure 2 firstly, for each conveying batch included in the target batch group, the target powder system is controlled to convey the powder of the conveying batch according to the conveying parameter corresponding to the conveying batch in step S100, and then the conveying precision of the target powder system conveying the powder of each conveying batch in the target batch group is acquired in step S200; then it is determined whether the conveying precision of the conveying batch is located within the first target precision range corresponding to the conveying batch in step S310; if located within the first target precision range, it is determined whether the batch number corresponding to the conveying batch is any target batch number in the preset plurality of target batch numbers in step S321; if the batch number corresponding to the conveying batch is not any target batch number, the conveying parameter corresponding to the conveying batch is determined as the conveying parameter corresponding to the next conveying batch in step S322; if the batch number corresponding to the conveying batch is any target batch number, for each predetermined conveying batch in the plurality of predetermined conveying batches before the conveying batch, the size of the preset powder demand weight value corresponding to the predetermined conveying batch and the powder actual conveying weight value corresponding to the predetermined conveying batch is compared in step S3231; if for each predetermined conveying batch, the preset powder demand weight value corresponding to the predetermined conveying batch is greater than the powder actual conveying weight value corresponding to the predetermined conveying batch, the sum of the valve closing time corresponding to the conveying batch and the preset valve closing delay value is determined as the new valve closing time, and the sum of the conveying speed corresponding to the conveying batch and the preset acceleration value is determined as the new conveying speed in step S3232; if for each predetermined conveying batch, the preset powder demand weight value corresponding to the predetermined conveying batch is not greater than the powder actual conveying weight value corresponding to the predetermined conveying batch, the difference between the valve closing time corresponding to the conveying batch and the preset valve closing advance value is determined as the new valve closing time, and the difference between the conveying speed corresponding to the conveying batch and the preset deceleration value is determined as the new conveying speed in step S3233.

[0098] Further, if not located in the first target precision range, it is determined in step S331 whether the conveying precision is located in a second target precision range, if located in the second target precision range, it is determined in step S3321 the size relation between the conveying precision and the upper and lower limit values of the first target precision range; if the conveying precision is greater than the upper limit value of the first target precision range, the difference between the conveying speed corresponding to the current conveying batch and the preset deceleration value is determined as the new conveying speed in step S3322, and the difference between the valve closing time corresponding to the current conveying batch and the preset valve closing advance value is determined as the new valve closing time; if the conveying precision is less than the lower limit value of the first target precision range, the sum of the conveying speed corresponding to the current conveying batch and the preset acceleration value is determined as the new conveying speed in step S3323, and the sum of the valve closing time corresponding to the current conveying batch and the preset valve closing delay value is determined as the new valve closing time. If not located in the second target precision range, it is determined in step S333 that the battery powder system fails.
