To make the foregoing objectives, features, and advantages of this application clearer and more understandable, examples are given hereinafter, and the detail description is made as below with reference to the accompanying drawings.
To describe the technical solutions in embodiments of this application more clearly, the following briefly describes the accompanying drawings required for describing some embodiments. It is appreciated that the accompanying drawings below show merely some embodiments of this application and thus should not be considered as limitations on the scope. Persons of ordinary skill in the art may still derive other related drawings from the accompanying drawings without creative efforts.
The following describes the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application.
It should be noted that similar reference numerals and letters indicate similar items in the following drawings, and therefore once an item is defined in one drawing, it does not need to be further defined or explained in the subsequent drawings. In addition, in the description of this application, the terms “first”, “second”, and the like are merely intended for distinctive description, and shall not be understood as an indication or implication of relative importance.
Through research by the inventor, it has been learned that in the battery production workshop, to ensure that a position of an electrode plate material strip during winding and unwinding can meet the requirements, for example, the material strip always staying at a center position of a rotating shaft without deviation, so as to complete the accurate cutting of tabs, the position of the material strip is usually monitored using an image acquisition device. For example, A CCD (charge coupled device) camera may be used to monitor the position of the electrode plate material strip in real time; and some control devices are used to perform deviation correction on the material strip in real time. In a slitting stage of the electrode plate material strip, after the slitting, the electrode plate material strip is divided into two parts, and a marking action needs to be performed at tail ends of the two strips. However, a slitting device, a marking device, a deviation correction device, and a device controlling movement of the electrode plate material strip result in complexity of various systems, because different devices need to be controlled by different control systems. However, the control of different devices also requires the use of operation data of other devices. Therefore, how to achieve an interaction method that allows for higher control efficiency of all devices and reduces control delays is a research direction.
Based on the foregoing requirements, a control system is provided. As shown in
The main control upper-level computer 110 may be configured to connect to various detection devices and obtain detection data from each detection device. It may also analyze the detection data from each detection device to determine, based on each analysis result, whether the electrode plate material strip needs to be processed, for example, whether the marking device and the deviation correction device need to be controlled.
The intermediate controller 120 is configured to acquire operation data of various driving devices, receive a control signal of the main control upper-level computer 110, and control the single-chip microcomputer 140. For example, if the electrode plate material strip needs to be marked, the main control upper-level computer 110 may send a detection signal to the intermediate controller 120, the intermediate controller 120 sends a control instruction to the single-chip microcomputer 140, and the single-chip microcomputer 140 controls the corresponding marking device to perform a marking operation.
The device controller 130 may be configured to control other slitting-related devices.
However, it has been known through research that in the control system, during the actual marking operation, the single-chip microcomputer 140 only passively receives relevant data of the intermediate controller 120 and controls the marking device based on the data or signal of the intermediate controller 120. Additionally, the intermediate controller 120 also needs to receive data of the main control upper-level computer 110. In the foregoing method, there is interaction among multiple control devices, and there are delays in data processing and interaction signals among the multiple control devices, which is likely to cause control instability under ultra-high-speed wire drawing.
Based on the above research, this application provides a device control method, which can improve the efficiencies of marking and deviation correction, and reduce marking delays. For example, the device control method provided in the embodiments of this application may be used in the slitting stage of the electrode plate material strip in the battery manufacturing process. The device control method in the embodiments of this application may be used for performing a deviation correction operation and a marking operation on the slit electrode plate material strip.

Refer to
The first detection signal is a command signal obtained by the upper-level computer upon detecting the quality of the target material strip. For example, the upper-level computer may obtain detection data from each detection device related to the target material strip, and then determine, based on the detection data, whether the target material strip can be marked. The first detection signal may include a marking signal for determining, based on the detection data, whether the target material strip can be marked.
The content included in the first detection signal may vary depending on different marking objectives.
The first detection signal may be used to indicate whether the first controller needs to mark the target material strip. For example, the marking signal may indicate whether the first controller needs to mark the target material strip.
In an embodiment, the marking signal of the first detection signal may be a detection pass signal or a detection fail signal. For example, the objective of marking on the target material strip is to mark a position at which the target material strip is unqualified. The marking signal of the first detection signal being a detection fail signal indicates that the target material strip can be marked. For example, the objective of marking on the target material strip may be to mark a position at which the target material strip is unqualified. The marking signal of the first detection signal being a detection fail signal indicates that marking may be performed at the position at which the target material strip is unqualified. For example, the objective of marking on the target material strip may be to mark the target material strip as a qualified material strip. The first detection signal being a detection pass signal indicates that the target material strip can be marked.
In another embodiment, the marking signal of the first detection signal may further be a signal indicating whether the target material strip can be marked. The upper-level computer may determine, based on the detection data, whether the target material strip can be marked. For example, the marking signal of the first detection signal may be a first indication signal, or the marking signal of the first detection signal may be a second indication signal. The first indication signal indicates that no marking is required, and the second indication signal indicates that marking is required. For example, the first indication signal may be signal “1”, and the second indication signal may be signal “0”.
Step 420: Determine a to-be-marked position on the target material strip based on the first detection signal.
The to-be-marked position may vary depending on the objective of the marking of the marker.
For example, the device control method may be used in the slitting stage of the electrode plate material strip in the battery production phase. After the slitting operation, the target material strip is divided into two parts. For example, the target material strip may be divided into a first target material strip and a second target material strip. The to-be-marked position may be a position on the first target material strip or a position on the second target material strip.
For example, the marking operation may also be to mark a position at which the target material strip is unqualified. Therefore, the to-be-marked position may be a position at which the target material strip is detected to be unqualified.
Optionally, the first detection signal may further include a position signal indicating the need for marking. The position signal is used to indicate a position that needs to be marked. The position may be a position, at which the target material strip is unqualified, requiring marking. For example, the position that needs to be marked may be at a certain distance from an end of the target material strip, and the position signal may be represented by the distance from the end of the target material strip. For example, the position signal may be indicated by a detection device. Based on the position of the detection device and the detection time, the relative position of the detection location on the target material strip may be determined when a detection result is obtained. For example, in addition to the marking signal characterizing the detection result, the first detection signal may include a position signal characterizing the position of the detection device. Based on the position of the detection device, the to-be-marked position on the target material strip that needs to be marked may be determined.
Optionally, the first detection signal may include a material strip signal indicating the need for marking, so based on the material strip signal, the material strip that needs to be marked may be determined. For example, the material strip signal may have two values. The material strip signal being a first value indicates the need to mark the first target material strip; and the material strip signal being the second value indicates the need to mark the second target material strip.
In an embodiment, the objective of the marker setting the mark is to indicate whether the material strip is qualified, and the first detection signal may include a marking signal indicating a detection result and a material strip signal obtained through detection.
For example, after the material strip enters the slitting stage, the material strip is slit into two parts. The material strip signal may be used to indicate whether the material strip that needs to be marked is the first target material strip or the second target material strip.
For example, if the currently received first detection signal is a detection signal for the first target material strip, and the first detection signal indicates qualification in the detection, marking may be performed, and the marker may be controlled to set a mark indicating qualification on the first target material strip of the target material strip. In another example, if the currently received first detection signal is a detection signal for the second target material strip, and the second detection signal indicates an anomaly in the detection, the marker may be controlled to set a mark indicating an anomaly on the first target material strip of the target material strip.
Optionally, if the entire first target material strip is detected to be qualified, the marker may set a mark indicating qualification on the first target material strip.
Optionally, segment marking may also be performed, and a mark indicating qualification or disqualification is set in each specified length region. In an example, if the length of the first target material strip is five kilometers, a mark indicating qualification or disqualification may be set every ten meters. For example, if the detection result indicates that the first target material strip from the tenth meter to the twentieth meter is qualified, a mark indicating qualification may be set at a specified position in this region. The specified position may be at the tenth meter from a starting point of this region, or at the twentieth meter from an ending point of this region. In another example, if the detection result shows that the first target material strip from the fiftieth meter to the sixtieth meter is detected to be abnormal, a mark indicating disqualification may be set at a specified position in this region.
In another embodiment, if the objective of the marker setting the mark is to record the production data of the material strip, the first detection signal may include detection data. The production data may include data such as the thickness of the target material strip and the width of the target material strip. For example, if the currently received first detection signal is a detection signal for the second target material strip, the marker may set a mark on the second target material strip, and the detection data from the second target material strip may be obtained via the mark. For example, the mark may be an identifiable barcode, QR code, string, or the like. The mark may record the production data of the second target material strip, and the production data of the second target material strip may be accessed via this mark.
To reduce the complexity of various control systems in the battery production process, more control functions may be integrated into the same controller. The first controller executes steps 440 to 460 to achieve the deviation correction of the target material strip.
The second detection signal is a signal determined by the upper-level computer upon detecting various positions of the target material strip.
The second detection signal may be a signal determined by the upper-level computer based on the detection data from the detection device. The detection device may be a CCD camera. Based on image data acquired by the CCD camera, whether there are deviations between various positions of the target material strip is determined.
For example, the second detection signal may include a position signal for position identification and a detection status signal. The detection status signal is used to indicate whether deviation correction is needed.
For example, multiple detection devices may be set up in the battery production workshop, and the position signal in the second detection signal may be determined based on the position of the detection device.
For example, the deviation correction position on the target material strip that needs deviation correction may be determined based on the above position signal.
If this method is used in the slitting stage of the electrode plate material strip in the battery production phase, the target material strip is divided into two parts after the slitting operation. The deviation correction position may be a position on the first target material strip of the target material strip, or a position on the second target material strip of the target material strip.
For example, the first controller may control the deviation corrector to work, so as to adjust the deviation correction position on the target material strip.
Optionally, after adjusting the deviation correction position, the detection device may also acquire an image of the deviation correction position in real time. The upper-level computer may determine whether there is a deviation at the deviation correction position based on the acquired image. If there is a deviation, the deviation of the target material strip may continue to be adjusted through steps 440 to 460.
Through the above steps, when it is needed to mark the target material strip, the controller may directly perform marking based on the detection signal of the upper-level computer, without the need for some intermediate controllers to forward the detection signal of the upper-level computer. This can improve the efficiency of marking the target material strip and reduce marking delays. Further, the first controller continues to complete the deviation correction of the target material strip. Completing the marking operation and deviation correction operation in one controller can reduce the complexity of the control systems in the battery production workshop. Moreover, from a maintenance perspective, the maintenance difficulty can be reduced and the technical skill requirements for engineers can be lowered.
The mark set by the marker on the target material strip may be used to identify a specific position. This specific position may be determined based on the operation data of the conveying mechanism that drives the movement of the target material strip. Based on this, as shown in
The first movement data may be used to characterize the movement case of the conveying mechanism. Because the conveying mechanism drives the movement of the target material strip, the movement distance of the target material strip may be determined based on the movement case of the conveying mechanism.
For example, the conveying mechanism includes multiple rollers and the circumference of one roller is s0, so the roller rotating one full turn may drive the target material strip to move by s0.
In response to the movement of the to-be-marked position on the target material strip to the marking position of the marker, step 423 is executed.
For example, if the distance between the marking position of the marker and the to-be-marked position on the target material strip is S1, after the conveying mechanism drives the target material strip to move by S1, it may be determined that the to-be-marked position on the target material strip moves to the marking position of the marker. The distance between the marking position of the marker and the to-be-marked position on the target material strip may represent the distance by which the to-be-marked position on the target material strip needs to move to the marking position of the marker under the action of the conveying mechanism.
In an optional embodiment, a driving assembly of the conveying mechanism is a servo motor. The first movement data of the conveying mechanism includes encoding data of an encoder of the servo motor. Step 421 may include obtaining the encoding data of the encoder of the servo motor of the conveying mechanism.
Based on the encoding data, the movement case of the conveying mechanism may be determined, and based on the movement case of the conveying mechanism, the movement case of the target material strip may be determined.
In the above implementation, the movement case of the target material strip may be determined based on the encoder data, allowing for more accurate marking at a position that needs to be marked.
In an optional embodiment, to allow the controller to clearly ascertain the completion case after it has controlled the marker to complete the marking operation, the driving assembly of the marker may be a servo motor. Step 423 may include: controlling the servo motor of the marker to move, so as to drive the marker to set the mark at the to-be-marked position on the target material strip; and obtaining the operation data of the servo motor of the marker.
After the servo motor of the marker is controlled to move, the operation data of the servo motor of the marker may be also obtained. Based on this operation data, whether the marking has been completed may be determined.
After the servo motor is controlled to move, the operation data of the servo motor may be also obtained. Based on the operation data, it may be known whether the marker has completed the marking operation, thereby achieving closed-loop control and better determining the completion case of the operation.
Through the above steps, the deviation correction operation may be performed at a position with a deviation on the target material strip, allowing for more accurate subsequent operation of cutting a tab on the target material strip, and making the manufactured batteries more compliant with requirements.
In an optional embodiment, multiple positions in the battery production workshop may be all provided with deviation correctors to meet the deviation correction requirements of different positions. Based on this, the deviation corrector may be determined based on the deviation correction position to adaptively adjust the position of the material strip. As shown in
The real-time movement case of the target material strip may be determined based on the second movement data.
Optionally, the real-time position of the deviation correction position on the target material strip may be determined based on the second movement data. The deviation corrector closest to the real-time position may be used as the target deviation corrector.
Optionally, based on the movement direction of the target material strip, the deviation corrector closest to the deviation correction position on the target material strip may also be determined as the target deviation corrector in the movement direction of the target material strip.
Optionally, the driving assembly of the deviation corrector may also be a servo motor. The servo motor of the target deviation corrector may be controlled to move, so as to control the target deviation corrector to adjust the deviation correction position on the target material strip. Optionally, the first controller may also obtain the operation data of the servo motor of the deviation corrector, to determine, based on the operation data, whether the target deviation corrector has completed the deviation correction operation.
Optionally, if there is a distance S2 between the position of the target deviation corrector and the deviation correction position on the target material strip, whether the target material strip has moved by S2 may be determined based on the second movement data. After the target material strip has moved S2, the target deviation corrector is controlled to adjust the deviation correction position on the target material strip.
In an embodiment, the deviation corrector may be arranged at a predetermined position in the battery production workshop, so deviation correction, when needed, may be achieved by the deviation corrector at the predetermined position. Based on this, the deviation correction operation needs to be performed after the deviation correction position with a deviation moves to the predetermined position of the deviation corrector. Based on this, as shown in
Based on the third movement data of the conveying mechanism, the movement distance of the conveying mechanism may be known, and based on the movement distance of the conveying mechanism, the movement distance of the target material strip may be determined.
For example, if the distance between the position of the deviation corrector and the deviation correction position on the target material strip is S3, after the conveying mechanism drives the target material strip to move by S3, it may be determined that the position of the target material strip has moved to the position of the deviation corrector. The distance S3 between the position of the deviation corrector and the deviation correction position on the target material strip may represent the distance by which the deviation correction position on the target material strip needs to move to the position of the deviation corrector under the action of the conveying mechanism.
In response to the movement of the deviation correction position on the target material strip to the position of the deviation corrector, step 456 is executed.
Based on the movement data of the conveying mechanism, the target material strip may be located in real time. Based on the real-time position of the target material strip, deviation correction can be more accurately performed at positions with deviations. Further, the first controller directly controlling the deviation corrector can reduce the interaction requirements between various control systems, reduce deviation correction delays, and improve the deviation correction efficiency.
Further, the deviation correction control and marking control are integrated in the first controller in the device control method of this application, which can reduce the data of the control systems required in the battery production workshop, lower the complexity of workshop device control, and improve the control efficiency of various devices in the workshop.
