[0056] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0057] 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.

[0058] The inventors' research revealed that in battery production workshops, ensuring the electrode strip's position meets requirements during unwinding and winding—for example, maintaining its position at the center of the rotating shaft to prevent deviation and thus accurately cut the electrode tabs—is achieved through image acquisition devices monitoring the strip's position. For instance, a CCD (charge-coupled device) camera can be used to monitor the electrode strip's position in real time. Control devices then correct the strip's deviation in real time. During the electrode strip slitting stage, after slitting, the electrode strip is divided into two parts, and marking is required at the ends of the two strips. However, the slitting equipment, marking equipment, deviation correction equipment, and equipment controlling the electrode strip's movement are complex systems, each requiring different control systems. Furthermore, controlling different equipment requires the use of operational data from other devices. Therefore, finding an interaction method that improves the control efficiency and reduces delay is a key research direction.

[0059] Based on the above requirements, a control system is provided, such as... Figure 1 As shown, the control system includes: a main control host computer 110, an intermediate controller 120, an equipment controller 130, and a marking microcontroller 140.

[0060] The main control computer 110 can be used to connect with various testing devices and obtain the testing data from each device. It can also analyze the testing data from each device to determine whether the electrode strip needs to be processed, such as whether the marking and correction equipment needs to be controlled.

[0061] The intermediate controller 120 is used to collect operating data from various driving devices, receive control signals from the main control computer 110, and control the marking microcontroller 140. For example, if marking is required on the electrode strip, the main control computer 110 can send a detection signal to the intermediate controller 120, which then sends a control command to the marking microcontroller 140, which in turn controls the corresponding marking equipment to perform the marking operation.

[0062] The aforementioned device controller 130 can be used to control other slitting-related equipment.

[0063] However, research revealed that in the aforementioned control system, during the marking operation, the marking microcontroller 140 can only passively receive relevant data from the intermediate controller 120 and control the marking equipment based on the data or signals from the intermediate controller 120. Additionally, the intermediate controller 120 also needs to receive data from the main control computer 110. This method involves interaction between multiple control devices, and there are delays in data processing and signal interaction between these devices, which can easily lead to control instability under ultra-high-speed cable handling.

[0064] Based on the above research, this application provides an equipment control method that can improve the efficiency of marking and correction, and reduce the delay in marking. For example, the equipment control method provided in this application can be used in the electrode strip slitting stage of battery manufacturing. The equipment control method in this application can be used to perform correction and marking operations on the slitting electrode strips.

[0065] To facilitate understanding of the embodiments of this application, the operating environment for implementing the device control method disclosed in the embodiments of this application will first be introduced.

[0066] This application provides a device control system. For example... Figure 2 As shown, the device control system may include a host computer 210 and a first controller 220.

[0067] The host computer 210 is used to connect to one or more external testing devices. The host computer 210 can communicate with the testing devices used to test electrode strips and can obtain testing data from each device. The testing device can be a laser sensor used to detect the thickness data of the electrode strip, or an image acquisition device used to detect the image data of the electrode strip.

[0068] The first controller 220 can be connected to the host computer 210. The first controller 220 can receive instructions transmitted by the host computer 210, and then the first controller 220 can control various devices. The first controller is used to implement the device control method provided in the embodiments of this application based on the control signals of the host computer.

[0069] For example, the first controller 220 may be a PLC (Programmable Logic Controller).

[0070] Optionally, the host computer 210 can establish a communication connection with the first controller 220 via TCP (Transmission Control Protocol) bus communication.

[0071] In one embodiment, the device control system can be used in the slitting stage of the electrode strip. The detection devices connected to the host computer 210 may include devices for detecting the width of the electrode strip or devices for detecting whether there is a positional offset in the electrode strip. The host computer 210 can also be connected to the first controller 220, which can determine whether the electrode strip needs to be marked or corrected based on the detection data from each detection device.

[0072] Optionally, the first controller 220 can also be used to control other auxiliary equipment during the slitting stage. Exemplarily, such auxiliary equipment includes: an air blowing device, an encoder, a clamping cylinder, etc.

[0073] Please refer to again Figure 2 As shown, the equipment control system may further include a second controller 230, which controls the slitting equipment (not shown) to slit the electrode strip. The slitting equipment may include more sub-equipment, and the second controller 230 can be used to control each sub-equipment in the slitting equipment.

[0074] For example, the second controller 230 may also be a PLC controller.

[0075] Optionally, the host computer 210 can also establish a communication connection with the second controller 230. The host computer 210 can obtain relevant data from the second controller 230, and the host computer 210 can also send detection signals and control signals to the second controller 230.

[0076] Optionally, the host computer 210 can establish a communication connection with the second controller 230 via TCP (Transmission Control Protocol) bus communication.

[0077] The first controller 220 and the second controller 230 can communicate via I / O (Input / Output) communication.

[0078] like Figure 3 The diagram shown is a block diagram of the controller. The controller 300 may include a memory 311 and a processor 313. Those skilled in the art will understand that... Figure 3 The structure shown is for illustrative purposes only and does not limit the structure of the controller 300. For example, the controller 300 may also include components that are more... Figure 3 The more or fewer components shown, or having the same Figure 3 The different configurations shown.

[0079] Figure 2 The first controller 220 and the second controller 230 shown may include Figure 3 The structure of the controller 300 is shown. Of course, the first controller 220 and the second controller 230 can also be compared. Figure 3 The controller 300 shown has a more detailed structure.

[0080] The memory 311 and processor 313 are electrically connected directly or indirectly to enable data transmission or interaction. For example, these components can be electrically connected to each other via one or more communication buses or signal lines. The processor 313 is used to execute executable modules stored in the memory.

[0081] The memory 311 can be, but is not limited to, Random Access Memory (RAM), Read Only Memory (ROM), Programmable Read-Only Memory (PROM), Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), etc. The memory 311 stores programs, and the processor 313 executes these programs upon receiving execution instructions. The methods executed by the controller 300, as defined in any embodiment of this application, can be applied to or implemented by the processor 313.

[0082] The aforementioned processor 313 may be an integrated circuit chip with signal processing capabilities. The processor 313 may be a general-purpose processor, including a Central Processing Unit (CPU), a Network Processor (NP), etc.; it may also be a digital signal processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. It can implement or execute the methods, steps, and logic block diagrams disclosed in the embodiments of this application. The general-purpose processor may be a microprocessor or any conventional processor.

[0083] The controller 300 in this embodiment can be used to execute various steps in the various methods provided in the embodiments of this application. The implementation process of the device control method is described in detail below through several embodiments.

[0084] Please see Figure 4 This is a flowchart of a device control method provided in an embodiment of this application. The method in this embodiment can be applied to a controller, for example, it can be controlled by... Figure 1 The first controller shown executes the steps in the method of this application embodiment. The following will describe... Figure 4 The specific process shown will be explained in detail.

[0085] Step 410: Receive the first detection signal sent by the host computer.

[0086] The first detection signal is a command signal obtained by the host computer from the quality detection of the target strip. For example, the host computer can acquire detection data of the target strip from various detection devices, and then determine whether the target strip can be marked based on the detection data. The first detection signal may include a marking signal that determines whether the target strip can be marked based on the detection data.

[0087] The content of the first detection signal can vary depending on the marking purpose.

[0088] The first detection signal can be used to indicate whether the first controller needs to mark the target strip. For example, the marking signal can be used to instruct the first controller whether to mark the target strip.

[0089] In one embodiment, the marking signal of the first detection signal can be either a pass signal or a fail signal. For example, marking on the target strip is used to mark the unqualified positions of the target strip. Therefore, when the marking signal of the first detection signal is a fail signal, it indicates that marking can be done on the target strip. Alternatively, marking on the target strip can be used to mark the unqualified positions of the target strip; in this case, when the marking signal of the first detection signal is a fail signal, it indicates that marking can be done at the unqualified positions of the target strip. Or, for example, marking on the target strip can be used to mark the target strip as a qualified strip; in this case, when the first detection signal is a pass signal, it indicates that marking can be done on the target strip.

[0090] In another implementation, the marking signal of the first detection signal can also be a signal indicating whether marking can be applied to the target strip. The host computer can determine whether the target strip can be marked based on the detection data. For example, the marking signal of the first detection signal can be a first indication signal or a second indication signal. The first indication signal indicates that marking is not required, and the second indication signal indicates that marking is required. For example, the first indication signal can be a signal "1", and the second indication signal can be a signal "0".

[0091] Step 420: Determine the marking position on the target strip based on the first detection signal.

[0092] The marking location may vary depending on the purpose of the marking device.

[0093] For example, the device control method can be used in the electrode strip slitting stage of battery production. After the slitting operation, the target strip is divided into two parts. For example, the target strip can be divided into a first target strip and a second target strip. The marking position can be a position on the first target strip or a position on the second target strip.

[0094] For example, the marking operation can also be to mark the location on the target strip where there is a defect. Therefore, the location to be marked can be the location on the target strip where a defect is detected.

[0095] Optionally, the first detection signal may further include a position signal capable of indicating the position to be marked. The position signal is used to indicate the position to be marked. The position may be a defective position on the target tape to be marked. For example, the position to be marked may be located at a certain distance from one end of the target tape, and the position signal may be represented by the distance from one end of the target tape. Exemplarily, the position signal may be represented by a detection device. Based on the position of the detection device and the detection time, when the detection result is obtained, the relative position of the detection position on the target tape can be determined. For example, in addition to the marking signal characterizing the detection result, the first detection signal may further include a position signal characterizing the position where the detection device is located. Based on the position where the detection device is located, the position to be marked on the target tape to be marked can be determined.

[0096] Optionally, the first detection signal may include a tape signal to be marked. Then, the tape to be marked can be determined according to the tape signal. For example, the tape signal may have two values. When the tape signal is the first value, it may indicate that marking is required on the first target tape; when the tape signal is the second value, it may indicate that marking is required on the second target tape.

[0097] Step 430, control the marker to set a mark at the position to be marked on the target tape.

[0098] In one implementation, the purpose of the mark set by the marker is to mark whether the tape is qualified. Then, the first detection signal may include a marking signal representing the detection result and the detected tape signal.

[0099] Exemplarily, after the tape enters the slitting stage, the tape will be slit into two parts. The tape signal can be used to indicate that the tape to be marked is the first target tape or the second first target tape.

[0100] For example, if the first detection signal currently received is a detection signal for the first target tape and the current detection of the first detection signal is qualified for marking, the marker can be controlled to set a mark indicating qualification on the first target tape in the target tape. For another example, if the first detection signal currently received is a detection signal for the second target tape and the current detection of the second detection signal is abnormal, the marker can be controlled to set a mark indicating abnormality on the first target tape in the target tape.

[0101] Optionally, when the overall detection of the first target tape is qualified, the marker can set a mark indicating qualification on the first target tape.

[0102] Optionally, the markings can be segmented, with a mark indicating pass or fail placed at intervals of a specified length. In one example, if the length of the first target strip is five kilometers, a mark indicating pass or fail can be placed every ten meters. For instance, if the inspection result for the tenth to twentieth meter of the first target strip is passable, a mark indicating pass can be placed at a specified position within this interval. This specified position could be the starting point of the interval (ten meters) or the ending point (twentieth meter). As another example, if the inspection result for the fiftieth to sixtieth meter of the first target strip is abnormal, a mark indicating fail can be placed at a specified position within this interval.

[0103] In another embodiment, the marking device sets a mark for recording production data of the material strip. The first detection signal can then include data representing the detection data. This production data can include information such as the thickness and width of the target material strip. For example, if the currently received first detection signal is for a second target material strip, the marking device can set a mark on the second target material strip, through which the detection data of the second target material strip can be obtained. For example, the mark can be a recognizable barcode, QR code, string, etc. This mark can record the production data of the second target material strip, and the production data of the second target material strip can be accessed through the mark.

[0104] To reduce the complexity of various control systems during battery production, more control functions can be integrated into a single controller. Steps 440 to 460 are executed by the first controller to correct the deviation of the target strip.

[0105] Step 440: Receive the second detection signal sent by the host computer.

[0106] The second detection signal is the signal determined by the host computer through detection at various positions of the target material strip.

[0107] The second detection signal mentioned above can be a signal determined by the host computer based on the detection data from the detection device. This detection device can be a CCD camera. The image data acquired by the CCD camera is used to determine whether there are deviations at various positions of the target material strip.

[0108] For example, the second detection signal may include a position signal for identifying the location and a detection status signal. The detection status signal is used to indicate whether correction is required.

[0109] For example, the battery production workshop can be equipped with multiple detection devices, and the position signal in the second detection signal can be determined based on the position of the detection devices.

[0110] Step 450: Determine the correction position on the target strip based on the second detection signal.

[0111] For example, the correction position on the target material strip that needs to be corrected can be determined based on the position signal mentioned above.

[0112] If this method is used in the electrode strip slitting stage of battery production, after the slitting operation, the target strip is divided into two. The correction position can be either a location on the first target strip or a location on the second target strip.

[0113] Step 460: Control the correction device to adjust the position of the correction point of the target strip.

[0114] For example, the first controller can control the correction device to operate in order to adjust the position of the correction device for the target strip.

[0115] Optionally, after adjusting the position of the correction position, the detection device can also acquire images of the correction position in real time. The host computer can determine whether there is a deviation in the correction position based on the acquired images. If there is a deviation, the deviation of the target material strip can be further adjusted through steps 440 to 460.

[0116] Through the above steps, when marking the target material strip is required, the controller can directly perform marking based on the detection signal from the host computer, eliminating the need for intermediate controllers to forward the host computer's detection signal. This improves the efficiency of marking the target material strip and reduces marking latency. Furthermore, the first controller continues to complete the target material strip correction. Completing both marking and correction operations within a single controller reduces the complexity of the control system in the battery production workshop. Moreover, from a maintenance perspective, it reduces maintenance difficulty and lowers the technical skill requirements for engineers.

[0117] For situations where the markings applied by the marking device on the target strip can be used to identify specific locations, these locations can be determined based on the operating data of the conveyor mechanism that drives the target strip. Based on this, such as... Figure 5 As shown, step 420 may include the following steps.

[0118] Step 421: Obtain the first movement data of the conveyor mechanism that controls the movement of the target material belt.

[0119] The first movement data can be used to characterize the movement of the conveyor mechanism. Since the conveyor mechanism drives the target material belt to move, the movement distance of the target material belt can be determined based on the movement of the conveyor mechanism.

[0120] For example, the conveying mechanism includes multiple rollers, one of which has a circumference of s0. When the roller rotates once, it can move the target material belt a distance of s0.

[0121] Step 422: Determine whether the marking position of the target strip has moved to the marking position of the marking device based on the first movement data.

[0122] In response to the target strip moving to the marking position of the marking device, step 423 is executed.

[0123] For example, if the distance between the marking point of the marking device and the marking position of the target strip is S1, then after the conveying mechanism moves the target strip by S1, it can be determined that the marking position of the target strip has moved to the marking point of the marking device. The distance between the marking point of the marking device and the marking position of the target strip can be expressed as the distance that the marking position of the target strip needs to move to the marking point of the marking device under the action of the conveying mechanism.

[0124] Step 423: Control the marking device to set a mark at the markable position on the target strip.

[0125] In an optional implementation, the drive component of the conveying mechanism is a servo motor. The first movement data of the conveying mechanism includes the encoded data of the encoder of the servo motor. Step 421 may include: acquiring the encoded data of the encoder of the servo motor of the conveying mechanism.

[0126] Based on this coded data, the movement of the conveyor mechanism can be determined, and based on the movement of the conveyor mechanism, the movement of the target material belt can be determined.

[0127] In the above implementation method, the movement of the target strip can be determined based on encoder data, which can more accurately mark the position where marking is required.

[0128] In an optional implementation, in order for the controller to clearly understand the completion status after the marking device completes the marking operation, the driving component of the marking device can be a servo motor; step 423 may include: controlling the movement of the servo motor of the marking device to drive the marking device to set a mark at the marking position on the target strip; and acquiring the servo motor operation data of the marking device.

[0129] After controlling the movement of the servo motor of the marking device, the operating data of the servo motor can be obtained, and the marking can be determined based on the operating data.

[0130] After controlling the movement of the servo motor, the operating data of the servo motor can be obtained. Based on the operating data, it can be determined whether the marking device has completed the marking operation, thus forming a closed-loop control and better determining the completion status of the operation.

[0131] The above steps can be used to correct deviations in the target strip, making subsequent tab cutting operations more accurate and ensuring that the manufactured batteries meet the requirements.

[0132] In one optional implementation, web guides can be installed at multiple locations within the battery production workshop to accommodate the web guiding requirements at different locations. Based on this, the web guides can be determined according to the web guiding location to adaptively adjust the position of the material strip. For example... Figure 6 As shown, step 450 may include the following steps.

[0133] Step 451: Obtain the second movement data of the conveyor mechanism that controls the movement of the target material belt.

[0134] The real-time movement of the target material strip can be determined using this second movement data.

[0135] Step 452: Based on the second movement data, determine the target correction device used to adjust the correction position.

[0136] Optionally, the real-time position of the correction point of the target strip can be determined based on the second movement data. The correction device closest to this real-time position can be used as the target correction device.

[0137] Optionally, based on the direction of movement of the target material strip, the correction device that is closest to the correction position of the target material strip in the direction of movement of the target material strip can be determined as the target correction device.

[0138] Step 453: Control the target correction device to adjust the position of the correction point of the target strip.

[0139] Optionally, the drive component of the correction device can also be a servo motor. The movement of the servo motor of the target correction device can be controlled to adjust the correction position of the target strip. Optionally, the first controller can also obtain the operating data of the servo motor of the correction device to determine whether the target correction device has completed the correction operation based on the operating data.

[0140] Optionally, if there is a distance S2 between the position of the target correction device and the correction position of the target strip, it can be determined whether the target strip has moved by S2 based on the second movement data. After the target strip has moved by S2, the target correction device is then controlled to adjust the position of the correction position of the target strip.

[0141] In one implementation, the correction device can be positioned at a designated location in the battery production workshop. Therefore, when correction is needed, it can be achieved using the correction device at that designated location. Consequently, the correction operation needs to be performed only after the deviation has been moved from the current correction location to the designated position of the correction device. Therefore, as... Figure 7 As shown, step 450 may include the following steps.

[0142] Step 454: Obtain the third movement data of the conveyor mechanism that controls the movement of the target material belt.

[0143] By using the third movement data of the conveyor, we can know how far the conveyor has moved, and then determine the movement distance of the target material belt based on the distance the conveyor has moved.

[0144] Step 455: Determine whether the correction position of the target strip has moved to the location of the correction device based on the third movement data.

[0145] For example, if the distance between the location of the correction device and the correction position of the target material strip is S3, then after the conveying mechanism moves the target material strip by S3, it can be determined that the location of the correction device has moved to the location of the correction device. Here, the distance S3 between the location of the correction device and the correction position of the target material strip can represent the distance that the target material strip needs to move from the correction position to the location of the correction device under the action of the conveying mechanism.

[0146] In response to the target strip's correction position moving to the location of the correction device, step 456 is executed.

[0147] Step 456: Control the correction device to adjust the correction position of the target strip.

[0148] By using the movement data of the conveyor mechanism, the position of the target material strip can be located in real time. Based on the real-time position of the target material strip, deviations can be corrected more accurately. Furthermore, the first controller directly controls the correction device, which reduces the need for interaction between various control systems, reduces correction delay, and improves correction efficiency.

[0149] Furthermore, since the equipment control method of this application integrates both the correction control and the marking control into the first controller, it can reduce the amount of data required by the control system in the battery production workshop, reduce the complexity of equipment control in the workshop, and thus improve the efficiency of equipment control in the workshop.
