Description

Technical Field

[0001] The present application relates to the field of intelligent manufacturing and automated production technology, and specifically, to a batching control system, method, and equipment for the production of positive electrode materials. Background Art

[0002] The positive electrode material is an important component of lithium-ion batteries. It is located on the positive electrode side of the battery and is responsible for storing and releasing lithium ions during the charging and discharging process. The performance of the positive electrode material directly affects the energy density, cycle life, safety and cost of the battery. In the production process of positive electrode materials, the batching link is the starting step of the positive electrode material production, which determines the composition and proportion of subsequent materials. Correct batching can ensure that the performance of the positive electrode material is stable and consistent and meets specific application requirements. If the batching is inaccurate, it may cause the performance of the positive electrode material to deteriorate, and even affect the performance and safety of the entire battery.

[0045] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0046] At present, the process of preparing positive electrode materials is highly dependent on manual operation, which not only leads to risks such as inaccurate weight and wrong use of raw materials, but also causes the positive electrode material proportion to be unable to be prepared according to the established proportion. In addition, due to the lack of real-time feedback mechanism, operators are unable to stop the wrong preparation behavior in time, which seriously threatens the quality and production safety of positive electrode materials.

[0047] Based on this, the embodiments of the present application provide a batching control system, method, and equipment for the production of positive electrode materials, which are described below through embodiments.

[0048] Example 1

[0049] To facilitate understanding of this embodiment, a batching control system for positive electrode material production disclosed in the embodiment of this application is first described in detail. Figure 1 The structural diagram of a batching control system for positive electrode material production shown in the figure, a batching control system for positive electrode material production provided in the present application, characterized in that the batching control system includes a code scanning module, a work order module and a host:

[0050] The work order module is used to determine the target production weight of the positive electrode material based on the weight data corresponding to the various ingredients of the positive electrode material, and send the target production weight to the host; the various ingredients flow into the code scanning module through the production line;

[0051] The code scanning module is used to scan the identification codes of the incoming ingredients to determine the types of the incoming ingredients, so as to send the incoming material sequence to the host after determining the types of all ingredients;

[0052] The host is used to determine the proportion of the positive electrode material based on the incoming material sequence, determine the target weight of multiple ingredients in the positive electrode material based on the proportion and the target production weight, and review the target weight of the white material in the positive electrode material;

[0053] The host is also used to start batching based on the approved target weight of the white material, and monitor the batching process in real time to obtain a positive electrode material of a target production weight.

[0054] The batching control system of the present application is applied to the production line and used in combination with the IMES system. The host is a smart device such as a computer, notebook, server, etc. with data processing and computing capabilities, and can also be an APP installed on a portable device such as a mobile phone. The production equipment is the production equipment that obtains the positive electrode material through each workstation on the production line. The weighing module of the production equipment is a module for weighing the ingredients through a weighing sensor, such as a reduction scale. The code scanning module is implemented based on a device that can scan codes, such as a code scanning gun. The work order module is a module that can automatically generate daily production tasks or weekly production tasks or other fixed-term production tasks. The host can communicate with the code scanning module, the work order module, and the weighing module, and the communication method can be wireless communication or wired communication.

[0055] There are many kinds of ingredients for the positive electrode material, but at least two kinds are included. The two ingredients described in the present application are black material and white material. The weighing module counts the weight data corresponding to the black material and the white material respectively, and the weight data is a numerical value, and the weight data of the black material and the weight data of the white material are input into the work order module.

[0056] The work order module is used to determine the target production weight of the positive electrode material based on the weight data corresponding to the various ingredients of the positive electrode material. The target production weight can be the total production on the day, or it can be the target production weight after the black material and the white material are used up, achieving the goals of on-demand production and zero inventory. The work order module can also automatically generate a work order plan, i.e., the target production weight of the positive electrode material, according to the order requirements, and monitor the production progress and inventory status in real time, effectively avoiding the occurrence of inventory backlogs and shortages, improving production efficiency and capital utilization, thereby avoiding the occurrence of inventory backlogs and shortages caused by the inefficiency of traditional inventory management methods. After the target production weight is calculated or generated by the work order module, the target production weight is sent to the host, where the ingredients all flow from one module to the next module through the production line. For example, in the present application, the various ingredients flow into the code scanning module through the beginning of the production line.

[0057] The code scanning module is started after the host receives the target production weight and outputs a start signal. The code scanning module is operated by a worker, and the start signal is received by the code scanning module to generate a reminder signal to remind the worker that a code scanning gun is needed to perform a code scanning operation. The code scanning module scans the identification codes corresponding to the various ingredients of the positive electrode material to obtain a scanning result. One ingredient corresponds to one identification code. The identification codes of the black material and the white material included in the ingredients are different. The type of the ingredient can be determined based on the identification code. The scanning result is obtained after manual scanning with a code scanning gun, and based on the When the scanning result shows that the ingredient corresponding to the identification code is the ingredient of the positive electrode material, incoming material data is generated. After the operator scans the identification code based on the barcode scanner, the operator determines the scanning order and the order in which the ingredients are put in based on the incoming material order. That is, if the black material flows in through the production line first, then if the identification code of the black material is scanned first, the order in which the ingredients are put in is black material first and white material later, and vice versa. After receiving all the ingredients, the corresponding order in which they are put in is determined based on the corresponding incoming material order. The put-in data includes the type of ingredients, the incoming material order, etc., and the put-in data of the multiple ingredients are sent to the host.

[0058] The code scanning module determines whether the ingredient is an ingredient corresponding to the positive electrode material based on the scanning result; if not, the host generates a third prompt signal for the ingredient.

[0059] The code scanning module obtains a scanning result after scanning the identification code. If the scanning result is failed, it means that the ingredient corresponding to the identification code is not the ingredient of the positive electrode material. The code scanning module generates a third prompt signal and gives a reminder based on the third prompt signal to avoid the phenomenon of wrong use of ingredients, thereby ensuring the safety of the positive electrode material. It can also generate corresponding records to remind operators and leaders to deal with the phenomenon of incorrect code scanning. When the scanning result shown is failed, it means that the ingredient corresponding to the identification code is the ingredient of the positive electrode material, and the ingredient corresponding to the identification code is added to generate feeding data.

[0060] After receiving the incoming material data, the host determines the ingredient ratio of the positive electrode material based on the order of addition corresponding to the incoming material data. Different order of addition corresponds to different ingredient ratios, that is, the order in which the ingredients are added can affect the microstructure and performance of the positive electrode material. The ingredient order can affect the kinetic parameters in the reaction process, such as reaction rate and temperature, etc. These parameters can further affect the structure and performance of the material. These microstructural characteristics have an important influence on the electrochemical properties of the positive electrode material. Then, different ingredient ratios will lead to different target weights of the corresponding ingredients to be used, so as to determine the target weights corresponding to the multiple ingredients based on the ingredient ratio and the target production weight, and push the target weight of the white material to the target reviewer in a preset push mode to review the target weight of the white material.

[0061] When the host is used to review the target weight of the white material in the positive electrode material, the host specifically includes:

[0062] Determining whether the target weight of the white material meets the preset white material weight range based on the preset review method;

[0063] If so, the host generates an audit pass signal to confirm that the target weight of the white material has been audited based on the audit pass signal.

[0064] In this embodiment, when the host pushes the target weight of the white material for review, the preset review method is automatically started, that is, the target weight is pushed to the corresponding target processing personnel, and the target processing personnel determines whether the target weight of the white material meets the preset white material weight range. If it is within the preset white material weight range, the target processing personnel determines that the review is passed and clicks to confirm. After the target processing personnel clicks to confirm, the host generates a review pass signal, and determines that the target weight of the white material is reviewed and passed based on the review pass signal. If it is not within the preset white material weight range, the target processing personnel denies the review and clicks to return. After the target processing personnel clicks to return, the host re-performs weight inspection and ratio calculation to improve the correctness of the ingredients. Other preset review methods can also be used, such as the host automatically reviews the target weight of the white material. If the target weight of the white material is within the preset white material weight range, the host automatically reviews and passes.

[0065] After calculating the target weight, the host controls the production equipment to feed materials based on the target weight, and controls the weighing module to collect and monitor the weight data of the feeding of the production equipment in real time to obtain multiple ingredients of the target weight, that is, the multiple ingredients reach the corresponding target weights respectively. If the target weight of the ingredients is 100KG, and the weighing module is a reduction scale, then after the weight change data generated by the weighing module reaches 90KG, the remaining 10KG of feeding is completed at a slow speed, so that the positive electrode material of the target production weight is produced in the production equipment according to the pre-set production module based on the ingredients of the target weight.

[0066] like Figure 2 As shown, when the host is used to determine the ingredient ratio of the positive electrode material based on the incoming material sequence, and to determine the target weight of multiple ingredients in the positive electrode material based on the ingredient ratio and the target production weight, it specifically includes:

[0067] The host confirms the proportion of chemical elements in the positive electrode material based on the incoming material sequence;

[0068] The host processes the ingredient ratio, the proportion of chemical elements in the preset ingredients, and the target production weight to obtain the target weights corresponding to the multiple ingredients.

[0069] In this embodiment, the host confirms the proportion of chemical elements in the positive electrode material based on the incoming material sequence, wherein the proportion of chemical elements corresponding to the incoming material sequence is preset in the host. After obtaining the incoming material sequence, the host immediately calls the proportion of chemical elements, that is, when the black material and the white material flow into the code scanning module through the production line, if the black material flows in first, the corresponding proportion of black and white ingredients can be 7:3, and if the white material flows in first, the corresponding proportion of black and white ingredients can be 6:4. Here, 7:3 and 6:4 are only schematic representations and have no practical significance. The host processes the proportion determined based on the incoming material sequence and the proportion of chemical elements in the preset ingredients and the target production weight to obtain the target weights corresponding to the various ingredients, wherein the proportion of chemical elements in the ingredients can be found from the relevant information of the ingredients. Taking black material as an example, if the proportion of a certain element required in the black material is 85%, the target weight = the proportion of the proportion of the black material corresponding to the black material × the target production weight ÷ 85%. This is a schematic representation, thereby determining the required target weights of the various ingredients.

[0070] like Figure 3 As shown, when the host is used to monitor the batching process in real time to obtain the positive electrode material of the target production weight, it specifically includes:

[0071] Real-time monitoring of weight change data generated by the production equipment when feeding the multiple ingredients, and determining whether the weight change data meets a preset threshold range;

[0072] If not, the production equipment and the host use a double verification mechanism to issue an alarm.

[0073] In this embodiment, the host collects the weight change data generated by the production equipment when the multiple ingredients are added in real time through equipment such as a reduction scale, and the weight reduction of the collected ingredients is the weight change data. A preset threshold range is set for the weight change data, and it is determined whether the weight change data meets the preset threshold range. Taking the black material as 100KG as an example, the preset threshold range is 100±2KG, and the black material can reach 98-102KG. If the weight of the production equipment when adding the materials is 97KG or 105KG, the production equipment and the host use a double verification mechanism for alarm prompts, thereby ensuring the strictness of the production equipment and the ingredient control system in controlling the weight of the ingredients, so as to ensure the performance and safety of the positive electrode material.

[0074] When the host is used for the production equipment and the host to use a double verification mechanism for alarm prompting, it specifically includes:

[0075] The production equipment issues an alarm based on the weight parameter on the control panel after batching, and generates a first prompt signal to the host;

[0076] The host verifies the weight change data based on the first prompt signal to obtain a verification result, and issues an alarm again based on the verification result.

[0077] In this embodiment, before the production equipment performs batching, weight parameters are pre-set on the control panel of the production equipment. The weight parameters include but are not limited to the weight of the remaining ingredients in the production equipment after feeding, the feeding speed, etc., and an alarm is given based on the weight parameters on the control panel after batching. That is, if the weight of the production equipment after the feeding is completed does not reach the corresponding numerical range of the weight parameters on the control panel, or the feeding speed does not meet the feeding speed requirements, etc., then the production equipment will give an alarm at this time so that the operator and the leader can deal with it as soon as possible, and generate a first prompt signal to the host. After receiving the first prompt signal, the host will verify the weight change data again, and calculate the feeding time based on the feeding start time and the feeding end time. If the feeding time and the weight change data do not meet the preset threshold range, the host will give an alarm by controlling the APP corresponding to the batching control system to remind that it needs to be handled as soon as possible.

[0078] The batching control system also includes a monitoring module;

[0079] When the host is used to monitor the batching process in real time to obtain the positive electrode material of the target production weight, it also specifically includes:

[0080] The monitoring module monitors the key operation of the production equipment for feeding materials according to the target weight of multiple ingredients to obtain a video stream segment, and sends the video stream segment to the host;

[0081] The host stores the video stream segments based on a preset storage method.

[0082] In this embodiment, the monitoring module includes a camera and a situation awareness device. The situation awareness device is a device based on situation awareness technology, so as to realize full monitoring of the batching process of the positive electrode material, and the monitoring module monitors the key operations of the production equipment to feed the target weight of multiple ingredients to obtain video stream fragments, such as scanning codes, feeding, etc., and sends the video stream fragments to the host. The host stores the video stream fragments according to a preset storage method. The preset storage mode is a three-layer storage directory of production batch, operation name, and production time, that is, the production batch is first used as the first layer storage directory, the operation name is the second layer storage directory, and the production time is the third layer storage directory. Once a batch of positive electrode materials is abnormal, the specific time and link of the problem can be quickly found through video slicing, which greatly shortens the problem troubleshooting time and improves the efficiency of problem solving.

[0083] The monitoring module of this application adopts full perception technology of the configuration process, combined with a voice prompt system, to provide operators with clear ingredient operation guidance, which not only improves the accuracy and efficiency of the operation, but also reduces the requirements for the operator's skill level, making the production process more transparent and controllable.

[0084] The host is used to monitor the batching process in real time to obtain the positive electrode material of the target production weight, and specifically includes:

[0085] The host assigns a production identification based on the produced positive electrode material, and calls the production information and video stream segment of the positive electrode material;

[0086] The host performs information association based on the production information of the positive electrode material, the video stream segment, and the production identification to obtain a production identification with information.

[0087] In this embodiment, after the production equipment produces the target production weight of the positive electrode material, the host assigns a production identification based on the produced positive electrode material. The production identification can be a barcode or a QR code, and the form is not limited here. After assigning the production identification, the host calls the production information and video stream fragments of the positive electrode material. The production information includes production batches, all operations, ingredient information, feeding information, etc. The video stream fragment is output by the monitoring module. The host performs information association based on the production information, video stream fragment, and production identification of the positive electrode material to obtain a production identification with information, that is, consumers or regulatory authorities can quickly obtain detailed information and production process records of the positive electrode material by scanning the production identification, thereby enhancing the transparency and credibility of the product, and establishing a positive electrode material finished product traceability system. Through full-process barcode management and control, full traceability from raw material storage to finished product delivery is achieved.

[0088] The following are examples of the actual use of this application, all of which show that this application has achieved relatively obvious effects:

[0089] (1) An advanced batching control system successfully deployed in the production workshop, which integrates high-precision weight collection, double verification mechanism, full-sensing operation, video traceability, production identification traceability and inventory and production plan optimization technology, aims to solve the problems of low batching accuracy, frequent human errors, opaque process, difficult traceability and poor inventory management in the production of positive electrode materials. This system not only significantly improves production efficiency and product quality, but also enhances product traceability and safety, meets the market demand for high-quality and high-safety standard products, and provides strong technical support for the transformation and upgrading of the chemical industry in the fields of intelligent manufacturing, quality and safety, human-computer interaction and supply chain management.

[0090] (2) At present, an intelligent batching, mixing and blending integrated batching control system has been successfully implemented in the production workshop. The system integrates the three major links of batching, mixing and batching, and realizes full automation and intelligent control. At the same time, the workshop material dispatching system realizes the automatic handling of raw materials after batching and unpacking by integrating AGV technology, which greatly improves the material flow efficiency. In the batching and additive feeding link, the old cumbersome manual operation has been completely replaced. The system automatically calculates the batch number of black and white materials, verifies the white material value, and accurately controls the batch cutting of materials, which significantly improves work efficiency and accuracy. When feeding additives, the andon system intelligently guides the operator to scan the code to feed the materials, and the system automatically monitors and automatically starts the high-speed mixer after completion, further ensuring the timeliness and accuracy of the operation. In the material discharge and discharge link, the andon system continues to play a role, automatically pushes the sampling task and controls the high-speed mixer discharge, thus realizing efficient, accurate and automated management from batching to mixing.

[0092] The present application also provides a method for controlling the ingredients used in the production of positive electrode materials. Figure 4 The figure shows a flow chart of a batching control method for positive electrode material production. The function implemented by the batching control method for positive electrode material production corresponds to the function of implementing a batching control system for positive electrode material production on the terminal device.
