Description

Technical Field

[0001] The utility model belongs to the field of chemical industry, in particular to a lithium ion electrolyte feeding system. Background Art

[0002] There are many types of materials used in the production of electrolytes, and the demand for each type of material is uncertain. During the design and mass production process, it is impossible to store all materials in tanks and feed them through pipelines. This leads to many uncertainties in production, such as: wrong type of material added, wrong amount of material added, which seriously affects the quality of the product and causes serious economic losses.

[0003] The problems with traditional solutions are: the type of material feed is completely dependent on manual inspection and confirmation, relying entirely on manual concentration, and there is no systematic management and control; the amount of material feed is determined by manual actions based on changes in the quantity on the scale, such as closing the valve, relying entirely on manual concentration and reaction sensitivity; the calculation of the material feed amount relies on paper records for confirmation and calculation, wasting a lot of manpower and time; the entire process relies on manual operation and control, and there is a great risk of quality abnormalities caused by abnormal human operation; electronic scales are shared, and all feeding pipes are together, which can easily lead to incorrect use of pipes and feeding into other kettles.

[0004] As intelligent factories are put into use by a large number of enterprises, intelligent systems such as ERP informatization, FCS fieldbus control system, DCS distributed control system, etc. have become a very important management system of intelligent factories, playing an increasingly important role. For example, CN114936836A discloses a production management system, method and application based on intelligent manufacturing, and its generation management method is:

[0005] Obtain formula sheets and process sheets, and assign production tasks through ERP planning sheets;

[0006] Based on the assigned production tasks, the valves are automatically opened in sequence according to the target weight of the formula to automatically feed the pipeline;

[0007] Based on the assigned production tasks, weigh the small ingredients on the small ingredient weighing table according to the prompt information;

[0008] Based on the assigned production tasks, start mixing / dispersing according to the prompt information;

[0009] Based on the assigned production tasks, choose to start the tank washing operation according to the prompt information;

[0010] After the above production process is completed, the generated materials can be packaged.

[0011] The above solution can only meet the needs of a relatively simple production system, where the products produced by this production system have a single raw material, no risk of raw material mismatch, and a simple pipeline layout.

[0012] In the production of electrolyte, there are hundreds of additives, and dozens of lithium salts and solvents. Different battery manufacturers have rich and diverse raw material compositions according to their R&D characteristics and product layout. This requires electrolyte manufacturers to have the ability to quickly produce and quickly switch production for the production of electrolytes of various formulas.

[0013] This ability requires great technical skills and concentration from the operator.

[0014] In the production of electrolyte, using the existing intelligent production management system is undoubtedly the only feasible way to reduce the difficulty of operation for operators. The problem is how to develop a production management system with low risk of raw material mismatch, simple and reliable operation according to the production characteristics of electrolyte manufacturers.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Example

[0041] refer to Figure 1 , a lithium ion electrolyte feeding system, comprising: a material container 1, a pipeline 2, a weighing unit 3, a management system terminal 4 and a management system 5; the pipeline 2 and the material container 1 are connected in a detachable manner; the management system terminal 4 is connected to the management system 5 in communication;

[0042] The material container 1 is used to contain raw materials of lithium-ion battery electrolyte and has first identity information;

[0043] The pipeline 2 is used to transport the raw material to a designated location and has second identity information;

[0044] The weighing unit 3 is used to weigh the material container 1 and has third identity information;

[0045] The management system terminal 4 is used to collect the first identity information, the second identity information, and the third identity information, and feed back to the management system 5;

[0046] The management system 5 is used to check and match the first identity information with the material information in the work order information, and check and match the second identity information with the pipeline information in the work order information according to the preset work order information;

[0047] At the same time, the management system 5 is also used to issue an alarm when the first identity information and the material information do not match or the second identity information and the pipeline information do not match;

[0048] The management system 5 is further used to establish a communication connection with the weighing unit 3 according to the third identity information, and track the weighing data fed back by the weighing unit 3, and to issue an alarm when the weighing data does not match the material weight information in the work order information.

[0049] In the production of lithium-ion electrolyte, there are many types of materials, and there are many types of equipment such as reactors and stirring kettles. Different materials need to go to different production equipment, that is, the designated locations mentioned above. In actual production, there are many material containers 1, many pipelines 2, and many weighing units 3;

[0050] Therefore, each material container 1 has its unique first identity information, and the first identity information of different material containers 1 is different. Similarly, the pipeline 2 and the weighing unit 3 are also the same.

[0051] In the process of production scheduling, it is already noted in advance in the work order information what kind of raw materials need to be loaded in the material container 1 of a certain first identity information in this shift, and the production staff can prepare the corresponding raw materials in the corresponding material container 1 according to the work order information in advance. In order to better avoid confusion during the production process, it is best to use a special barrel for a special purpose, that is, a material container 1 of a certain first identity information is only loaded with one kind of raw material from beginning to end.

[0052] There are many ways to realize the detachable connection between the material container 1 and the pipeline 2, such as snap connection, threaded connection, sealed connection between an elastic pipeline and a rigid pipeline, sealed connection based on a sealing ring, etc., which are not excessively limited in this embodiment.

[0053] The weighing unit 3 is required to have at least weighing function and communication function. Many electronic scales with Internet of Things functions on the existing market are applicable to this embodiment. The communication connection described in this embodiment is not only a wired communication connection, but also includes an Internet of Things communication connection based on 4G or 5G.

[0054] The management system 5 and the management system terminal 4 are both provided by the system supplier. This embodiment only utilizes the relevant functions of the system and the terminal for configuration and organically combines and configures the company's material container 1, pipeline 2, and weighing unit 3 to achieve the basic functions of this embodiment. This embodiment does not involve in-depth development and design of software and code.

[0055] The basic production control process of this embodiment is:

[0056] The work order information is generated in advance. The work order information is generally generated by an additional ERP (Enterprise Resource Planning) system. In this embodiment, the more mature SAP (System Applications and Products) system 6 in the ERP system is selected for generation; the production personnel add the corresponding raw materials to the specified material container 1 in advance according to the work order information; the work order information includes the following specific information: material information, pipeline information, and material weight information, wherein the material information includes the first identity information and the material type information, and the pipeline information includes the second identity information of the pipeline 2 and the destination device connected to the pipeline 2; the material weight information includes the weight required to add the material and the allowable error.

[0057] The work order information exists in two forms: electronic and paper. The electronic work order information is sent to the management system 5, and the paper work order information is handed over to the on-site production personnel; the management system 5 reads the work order information and waits for relevant information from the management system terminal 4;

[0058] After the on-site production personnel obtain the paper work order information, they look for the corresponding material container 1 and pipeline 2 according to the first identity information and the second identity information on the work order information; they look for a nearby weighing unit 3 to obtain the first identity information, the second identity information, and the third identity information of the material container 1, the pipeline 2, and the weighing unit 3; the first identity information, the second identity information, and the third identity information are generally in the form of a barcode or a QR code, or can be a string in the form of a number or character number. If it is the latter, the on-site production personnel are required to manually input the string in the management system terminal 4; the preferred method of obtaining is to scan the code.

[0059] The management system terminal 4 sends the first identity information, the second identity information, and the third identity information to the management system 5, and the management system 5 verifies the material information and the pipeline information in the work order information stored therein, matches them after the verification, and establishes a communication connection based on the third identity information and the corresponding weighing unit 3; after a successful match, information will be sent to the system management terminal, prompting the system management terminal and the production personnel to proceed to the next step; if an error occurs in the verification, an alarm will be generated; the alarm can be sounded on the management system 5, and the monitoring personnel of the management system 5 will inform the production personnel of the alarm information through the intercom and stop the next step; the most preferred embodiment is: the alarm is sent to the management system terminal 4 in the form of an alarm message, the management system terminal 4 receives the alarm, the production personnel check the cause of the error according to the alarm information, and re-enter the first identity information, the second identity information, and the third identity information after eliminating the cause of the relevant error.

[0060] When the production personnel proceed to the next operation, the weighing unit 3 that has established a communication connection with the management system 5 will periodically send the weighing data to the management system 5. After the material transportation is completed, the management system 5 will calculate whether the material is delivered to the pipeline 2 according to the set weight and the allowable error. If so, the next type of material will be transported and the above process will be repeated. If not, an alarm will be issued and sent to the management system terminal 4 in the form of an alarm message.

[0061] In this embodiment, the management system 5 is a MES (Manufacturing Execution System) system or a T-MES system; the management system terminal 4 is a handheld terminal having a display interface and an operation panel. If the above identity information is transmitted to the handheld terminal in the form of a scan code, the terminal should also be configured with a scanning module. The management system terminal 4 described in this embodiment is a PDA terminal provided by a T-MES system supplier.

[0062] In the preferred scheme of this embodiment, the management system terminal 4 is also used to: pre-acquire work order information, and display the material information, pipeline information, and material weight information in the work order information on the display interface; when the management system terminal 4 obtains the first identity information and the second identity information, the first identity information and the material information are bound, and the second identity information and the pipeline information are bound; the work order information is manually input through the operation panel or remotely obtained from the SAP system 6.

[0063] Preferably, the work order information is input by the operator on the operation panel. The operator inputs the material information, pipeline information, and material weight information in the work order information into the management system terminal 4, and the display interface of the management system terminal 4 will display the input work order information; after the operator scans the first identity information and the second identity information, the management system terminal 4 will automatically match the first identity information, the second identity information, and the material information and pipeline information in the work order information; if the match is wrong, the operator confirms whether the material container 1 and pipeline 2 are scanned incorrectly, finds the corresponding correct material container 1 and pipeline 2 to scan, until the match is correct. If the match is still not correct, you should check whether your work order information is input correctly.

[0064] Preferably, a server 7 is also included, and the server 7 is used to store the work order information obtained by the management system 5, the information generated by the management system 5 during the verification and matching process, the weighing data generated by the interaction between the management system 5 and the weighing unit 3, and the information generated by the alarm of the management system 5. The server 7 is a local server or a cloud server. The above information is stored in the server 7, which is conducive to the traceability and tracking of production and the re-analysis of production failures.

[0065] Preferably, at least one of the material container 1 and the pipeline 2 has a power module for driving the raw materials in the material container 1 to be transported into the pipeline 2 .

[0066] The power module described here can be a pump or a pressurizing module arranged on the material container 1. The pressurizing module is generally an inert gas pressurizing module. If a pressurizing module is set, it is required that the material container 1 should be a sealable container with a certain pressure resistance; the power module described in this embodiment can also be a pump on the pipeline 2.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
