Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and more specifically, to a method and system for marking and controlling battery electrodes. Background Technology

[0002] Currently, with the development of new energy vehicles and energy storage batteries, the demand is increasing. In order to improve production efficiency, our equipment production cycle and speed are required to be faster and faster. In the electrode production process, materials are transported between different process equipment via a roll. Due to high-speed production, the speed of the electrode material conveyor belt and the winding speed are also getting faster and faster. When a roll of material is about to be used up, this scenario needs to be identified in advance. Otherwise, the electrode will continue to move at high speed until all the material on the roll is used up. However, at this time, high-speed movement will cause the belt to fly off, and the equipment will suddenly break the tension and stop abruptly. This will have a significant impact on the life of the equipment's geared motor, etc., which will not only waste materials, but also waste a lot of manpower and reduce production efficiency. Summary of the Invention

[0003] The purpose of this application is to provide a method, system, electronic device and computer-readable storage medium for marking and controlling battery electrodes, which can achieve the technical effect of improving the production efficiency of battery electrodes.

[0005] In the above implementation process, the battery electrode marking control method controls the battery electrode production equipment to run at a low speed (first speed) to continuously mark the material, thereby marking the material with continuous markings. Then, the battery electrode production equipment is controlled to run at a high speed (second speed) to obtain a battery electrode material roll, and the bottom of the battery electrode material roll has continuous markings. When the battery electrode material roll enters the next production process, since the production equipment is running at high speed, when the roll of battery electrode material is about to be used up, the unwinding sensor (sensing and identification unit) of the production equipment will identify the electrode markings, thereby slowing down and stopping the machine. This avoids electrode strip breakage and slippage during high-speed movement, and avoids wasting tens of minutes of splicing time and materials due to broken strips and slippage. This effectively improves the technical effect of battery electrode production efficiency.

[0006] Further, the step of controlling the battery electrode production equipment to run at a first speed for a preset length according to the continuous identification control signal includes: Obtain the contact position information of the battery electrode material; Based on the contact position information, the contact position of the battery electrode material is detected.

[0012] In the above implementation process, after the battery electrode material roll enters the next production process, when the roll of battery electrode material is almost used up, the sensor (sensing identification unit) of the equipment in this process can detect the continuous markings, reduce the speed until the machine stops, stop production, and replace it with a new roll of material.

Detailed Implementation

[0031] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0032] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Generally, battery electrode production equipment has sensors at the unwinding and rewinding points to detect the diameter of the roll. However, the accuracy of these sensors cannot accurately identify the thickness of the electrode, leading to misjudgment of the roll diameter at the unwinding or rewinding point. If the roll diameter data sensed by the roll diameter sensor is used as the only signal that the material on the roll has been used up before any special markings are made on the electrode, the roll diameter sensor will alarm. At this time, the material can still continue to move for several meters, and the material will be scrapped and wasted. If the employee continues to produce the remaining material by observation and judgment, manpower and time have already been wasted, and the stop point cannot be controlled properly, which may lead to the roll flying. To address the aforementioned technical problems, this application provides a method, system, electronic device, and computer-readable storage medium for marking and controlling battery electrode sheets. The method involves controlling the battery electrode sheet production equipment to operate at a low speed (first speed) to continuously mark the material, thereby imprinting continuous markings on the material. Then, the equipment is controlled to operate at a high speed (second speed) to obtain a battery electrode sheet roll, with continuous markings at the bottom. When the battery electrode sheet roll enters the next production process, since the production equipment operates at high speed, when the roll is about to be used up, the unwinding sensor (sensing and identification unit) of the production equipment will recognize the electrode sheet markings, thereby slowing down and stopping the machine. This avoids electrode sheet breakage and tape slippage during high-speed operation, and prevents the equipment from wasting tens of minutes of rewinding time and materials due to tape breakage and tape slippage, effectively improving the technical efficiency of battery electrode sheet production.

[0034] Please see Figure 1 and Figure 2 , Figure 1 This is a flowchart illustrating a battery electrode identification control method provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a battery electrode production equipment provided in an embodiment of this application. The battery electrode production equipment includes an unwinding shaft 50 and a rewinding shaft 60. A tape receiving platform 10, a die-cutting unit 20, a vision inspection unit 30, and an marking unit 40 are sequentially arranged between the unwinding shaft 50 and the rewinding shaft 60. Figure 2 A shows the direction of movement of the battery electrode material; the identification and control method for this battery electrode includes the following steps: S100: Obtain roll / material change information; For example, when the unwinding shaft 50 of the battery electrode production equipment runs out of material or the rewinding shaft 60 is full of material, it is necessary to perform a rewinding and material changing operation on the battery electrode production equipment. At this time, by obtaining the corresponding rewinding and material changing information, the operator is reminded to perform the rewinding and material changing operation on the battery electrode production equipment. S200: Generates continuous identification control signals based on roll change and material change information; When operators perform roll changing and material changing operations on battery electrode production equipment, they continuously mark the materials according to the continuous marking control signal to continuously mark the materials.

[0035] S300: Controls the battery electrode production equipment to run at a first speed for a preset length according to the continuous identification control signal; S400: Controls the battery electrode production equipment to perform continuous marking operations on materials and generates a continuous marking completion signal; S500: Based on the continuous identification signal, the battery electrode production equipment is controlled to run at a second speed to obtain a battery electrode material roll, wherein the second speed is greater than the first speed.

[0036] For example, before the battery electrode production equipment performs continuous marking operation on the material, the battery electrode production equipment runs at a low speed at a first speed to facilitate continuous marking operation on the material; after the continuous marking operation is completed, the battery electrode production equipment is controlled to run at a high speed at a second speed so that the battery electrode production equipment can produce normally and obtain a battery electrode material roll, and the bottom of the battery electrode material roll has continuous marking.

[0037] For example, the battery electrode marking control method controls the battery electrode production equipment to run at a low speed (first speed) to continuously mark the material, thereby marking the material with continuous markings. Then, it controls the battery electrode production equipment to run at a high speed (second speed) to obtain a battery electrode material roll, and the bottom of the battery electrode material roll has continuous markings. When the battery electrode material roll enters the next production process, since the production equipment is running at high speed, when the roll of battery electrode material is about to be used up, the unwinding sensor of the production equipment will recognize the electrode markings, thereby slowing down and stopping the machine. This avoids electrode strip breakage and slippage during high-speed movement, and avoids wasting tens of minutes of reconnection time and materials due to strip breakage and slippage, effectively achieving the technical effect of improving the production efficiency of battery electrodes.

[0038] Please participate Figure 3 , Figure 3 This is a flowchart illustrating another method for controlling the marking of battery electrodes provided in an embodiment of this application.

[0039] For example, S300: The step of controlling the battery electrode production equipment to run at a first speed for a preset length according to the continuous identification control signal includes: S310: Obtain the contact position information of the battery electrode material; S320: Based on the contact position information, the contact position of the battery electrode material is detected. The die-cutting unit of the battery electrode production equipment performs the first marking hole operation on the battery electrode material to obtain the first marking hole. S330: Controls the battery electrode production equipment to run at a first speed according to the first marking hole and the continuous marking control signal, and cuts the battery electrode material to a preset length. The preset length is determined according to the battery electrode production parameters.

[0040] For example, when the operator performs a roll change and material change operation on the battery electrode production equipment, a first marking hole is cut on the battery electrode material at the tape splicing position. The first marking hole can be used as the first piece of material to be picked up from this roll. After the first marking hole is cut, the battery electrode material is cut to a preset length. This preset length is used as the material length reserved at the bottom of the tube. The material reserved at the bottom of the tube is used as the tape length distance for the next process equipment after receiving the continuous marking signal from high speed to stop, so as to avoid the electrode tape breaking and flying.

[0041] For example, S400: The step of controlling the battery electrode production equipment to perform continuous marking operations on materials and generating a continuous marking completion signal includes: S410: The second marking hole is obtained by performing a second marking hole cutting operation on the battery electrode material through the die-cutting unit; S420: Control the battery electrode production equipment to perform continuous marking operation on the materials according to the second marking hole, and generate a continuous marking completion signal, wherein the number of continuous markings is greater than or equal to 4.

[0042] For example, the material is continuously marked starting at the second marking hole, and the distance between the first marking hole and the second marking hole is the preset length, which serves as the material length reserved at the bottom of the pipe.

[0043] For example, S420: The step of controlling the battery electrode production equipment to continuously mark materials according to the second marking hole and generating a continuous marking completion signal includes: Based on the contact position information, the contact position of the battery electrode material is detected to reach the take-up shaft 60 of the battery electrode production equipment. The take-up shaft 60 is then used to change the roll and unload the material, and the empty roll is installed onto the take-up shaft 60. Update the membrane roll number information of the empty roll; When the second marking hole of the battery electrode material is detected to have reached the marking unit of the battery electrode production equipment, the battery electrode production equipment is controlled to perform continuous marking operation on the material and generate a continuous marking completion signal.

[0044] For example, after step S500: controlling the battery electrode production equipment to run at a second speed according to the continuous identification completion signal to obtain a roll of battery electrode material, the method further includes: S510: The battery electrode material roll enters the next process of battery electrode production; S520: In the next process of battery electrode sheet production, production control is performed based on the continuous markings on the battery electrode sheet material roll.

[0045] For example, after the battery electrode material roll enters the next production process, when the roll of battery electrode material is almost used up, the sensor (sensing identification unit) of the process equipment can detect the continuous markings, reduce the speed until it stops, stop production, and replace it with a new roll of material.

[0046] Please see Figure 4 , Figure 4 This is a schematic diagram of the process for obtaining roll changing and material changing information provided in an embodiment of this application.

[0047] For example, the battery electrode production equipment includes an unwinding shaft 50 and a rewinding shaft 60. S100: The step of obtaining rewinding and material changing information includes: S110: Detects the winding diameter data of the take-up spool and generates a sudden change signal in the winding diameter; S120: Detects the unwinding shaft diameter data and generates an unwinding diameter abrupt change signal; S130: Obtain the shaft change production signal; S140: Generate roll change and material change information based on one or more of the following: take-up roll diameter change signal, unwind roll diameter change signal, and shaft change production signal.

[0048] For example, the corresponding roll diameter signal can be obtained through the roll diameter sensor; then, the start of the roll changing and material changing operation of the battery electrode production equipment can be obtained through the roll diameter change signal or the unwinding roll diameter change signal, as well as the shaft changing production signal, thereby generating the corresponding roll changing and material changing information.

[0049] For example, the battery electrode production equipment includes an identification unit 40. S400: The step of controlling the battery electrode production equipment to perform continuous identification operations on materials and generating a continuous identification completion signal includes: The control identification unit 40 performs continuous identification operations on the materials and generates a continuous identification completion signal.

[0050] Please see Figure 5 , Figure 5 This is a schematic diagram of the production process of the battery electrode material roll provided in the embodiments of this application.

[0051] In some implementations, combined Figures 1 to 5 The aforementioned marking and control method for battery electrodes can be applied to the die-cutting process during battery electrode production. Taking the die-cutting process as an example, the specific implementation steps are as follows: Step 1: Change the material roll at the unwinding / rewinding point of the die-cutting equipment; The criteria for determining whether a material roll replacement operation is required include one or more of the following: 1.1 After changing the material and splicing the tape at the unwinding point, the roll diameter detector at the unwinding point detects that the roll diameter suddenly changes from less than 330mm to more than 360mm, and obtains the unwinding roll diameter change signal; 1.2 After the material roll is changed at the winding point, the roll diameter detector at the winding point detects that the winding roll diameter suddenly changes from greater than 360mm to less than 330mm, and obtains the winding roll diameter change signal; 1.3. Shaft change production at the winding / unwinding point, obtaining the shaft change production signal; Optionally, the size of the rolls may vary between different factories. The roll diameter of the example factory is 320mm. The roll diameter tests of 360mm and 330mm are only examples and not limitations. Step 2: Based on one or more of the following signals: unwinding roll diameter change signal, rewinding roll diameter change signal, and shaft change production signal, the die-cutting process equipment enters the continuous identification program; After the die-cutting equipment enters the continuous marking program, the die-cutting equipment can continuously mark the material on the strip through the marking unit 40, that is, mark the material with continuous markings; the number of markings can be determined according to actual needs. Here, four labels are used as an example. Four consecutive labels are applied to the material so that after the die-cutting equipment performs the roll change operation, it enters the four-labeling program. Step 3: After the die-cutting equipment enters the continuous marking program (four-marking program), the die-cutting equipment runs at a low speed according to the set first speed. For example, the first speed can be 10m / min. Step 4: When the strip enters the die-cutting unit 20, the die-cutting unit 20 performs laser skip cutting. After skip cutting, the die-cutting unit 20 automatically performs reset punching. The die-cutting unit 20 re-cuts the strip and punches the first Mark hole (first cutting mark hole) on the first cell after re-cutting. The first Mark hole (first cut mark hole) can be used as the first piece of material picked up by the employee for this roll of material; after the die-cutting unit 20 performs laser skip cut, it stops cutting the strip; after the die-cutting unit 20 performs reset punch cut, it re-cuts the strip. Step 5: After the die-cutting unit 20 performs reset punching and cuts the battery electrode material to a preset length, it resets and punches again, and punches the second Mark hole (second cutting mark hole) on the first cell after recutting. Then, it performs normal die-cutting of the material strip according to the required cell length and size. The preset length can be set according to actual needs, such as 3-5 meters. The preset length is used as the length of material reserved at the bottom of the pipe. The material reserved at the bottom of the pipe is used as the conveyor belt length distance from high speed to stop after the next process equipment receives the continuous marking signal. Step 6: When the second Mark hole reaches the position of the marking unit 40, the marking unit 40 starts to execute the four-marking program, marking four consecutive marks on the strip. After the four consecutive marks are completed, the marking completion signal is obtained, and the four-marking program is completed. Step 7: The die-cutting equipment operates normally at the set second speed according to the completion signal. The second speed is greater than the first speed. After four consecutive markings are completed, the die-cutting equipment automatically increases its speed from the first speed to the second speed and operates normally. For example, through steps 1 to 7, the roll of material removed from the winding section of the die-cutting process equipment has four consecutive identifiers; the roll of material is transported to the next process, and when the material on the roll is almost used up at the unwinding end of the next process equipment, the sensing and identification unit of the next process equipment senses the four consecutive identifiers, automatically stops production, and replaces the roll with a new one.

[0052] Please see Figure 6 , Figure 6 This is a structural block diagram of a battery electrode marking control system provided in an embodiment of this application. The battery electrode marking control system includes: Module 100 is used to acquire roll change and material change information; The identification control module 200 is used to generate continuous identification control signals based on roll change and material change information.

The second production control module 500 is used to control the battery electrode production equipment to run at a second speed according to the continuous identification completion signal to obtain the battery electrode material roll, wherein the second speed is greater than the first speed.

[0053] For example, the first production control module 300 is further configured to: Obtain the contact position information of the battery electrode material; Based on the contact position information, the contact position of the battery electrode material is detected. The die-cutting unit of the battery electrode production equipment performs the first marking hole operation on the battery electrode material to obtain the first marking hole. The battery electrode production equipment is controlled to run at a first speed according to the first marking hole and the continuous marking control signal, and the battery electrode material is cut to a preset length. The preset length is determined according to the battery electrode production parameters.

[0054] For example, the first production control module 300 is further configured to: The second marking hole is obtained by performing a second marking hole cutting operation on the battery electrode material through the die-cutting unit; The battery electrode production equipment controls the second marking hole to perform continuous marking operation on the materials and generate a continuous marking completion signal, wherein the number of continuous markings is greater than or equal to 4.

[0055] For example, the first production control module 300 is further configured to: Based on the contact position information, the contact position of the battery electrode material is detected to reach the take-up shaft of the battery electrode production equipment. The take-up shaft is changed and the empty roll is installed onto the take-up shaft. Update the membrane roll number information of the empty roll; When the second marking hole of the battery electrode material is detected to have reached the marking unit of the battery electrode production equipment, the battery electrode production equipment is controlled to perform continuous marking operation on the material and generate a continuous marking completion signal.

[0056] For example, the second production control module 500 is further configured to: The battery electrode material roll enters the next process of battery electrode production; In the next process of battery electrode sheet production, production control is carried out based on the continuous markings on the battery electrode sheet material roll.

[0057] For example, the battery electrode production equipment includes an unwinding shaft and a rewinding shaft, and the acquisition module 100 is further configured to: Detect the winding diameter data of the take-up spool and generate a sudden change signal in the winding diameter; Detect the unwinding shaft diameter data and generate an unwinding diameter abrupt change signal; Acquire the shaft change production signal; Based on one or more of the following signals: sudden change in winding diameter, sudden change in unwinding diameter, and shaft change production signal, roll change and material change information is generated.
