Description

Technical Field

[0001] The present application relates to the field of control, and in particular, to a coating control system and a coating control method. Background Art

[0002] In the production of coating equipment, cathode and anode materials are coated on a current collector. The current collector comes in the form of a roll. The roll is unwound by a pay-off reel, and then after processes such as slurry coating, drying, and inspection, it is wound by a take-up reel.

[0003] In the related art, in order to trace production data, during the winding process, when the roll at the waiting position is loaded, an artificial trigger is used to request the Manufacturing Execution System (MES) to issue a roll number of this roll of material. There is a situation where the roll number application is forgotten.

[0004] The above statements are only used to provide background technical information related to the present application, and do not necessarily constitute prior art. Summary of the Invention

[0005] One technical problem to be solved by the present application is to provide a coating control system and a coating control method that can automatically obtain the roll identification and reduce the situation where the roll identification cannot be obtained.

[0006] In a first aspect, the present application provides a coating control system, including: a rotating mechanism for performing a roll change operation to rotate the roll at the waiting position to the winding station, where an electronic tag is provided on the roll, and the electronic tag carries the roll identification of the roll; a winding mechanism for performing a winding operation to wind the rolled material onto the roll at the winding station, where the rolled material is a section of coated film; a first reader provided at the waiting position for reading the electronic tag provided on the roll at the waiting position; a controller electrically connected to the first reader and configured to obtain the roll identification from the first reader before the rotating mechanism performs the roll change operation and send it to the Manufacturing Execution System; and a Manufacturing Execution System electrically connected to the controller and configured to generate a roll identification corresponding to the rolled material before the winding mechanism performs the winding operation, where the roll identification and the roll identification of the roll correspond.

[0007] In the technical solution of the embodiment of the present application, by setting an electronic tag and a reader, the reader reads the roll identification in the electronic tag, and then the controller sends the roll identification to the Manufacturing Execution System. The Manufacturing Execution System generates a roll identification corresponding to the rolled material, and the roll identification corresponds to the roll identification, thereby realizing the automatic acquisition of the roll identification, eliminating the process of manually requesting the roll number, and further reducing the probability of not being able to obtain the roll identification.

[0008] In some embodiments, the electronic tag is located on the end face of the reel; and the first reader is disposed on the rack at the waiting position, and when the reel is at the waiting position, the electronic tag is within the reading range of the first reader. Through the description of the positions of the electronic tag and the first reader, the content of the electronic tag can be obtained, improving the efficiency of obtaining the reel identification.

[0009] In some embodiments, the controller is further configured to obtain production data related to the web stock, wherein the production data corresponds to the reel identification and the web stock identification. By correlating the production data with the reel identification and the web stock identification, the reliability of film roll data traceability is improved.

[0010] In some embodiments, the controller is further configured to send a first request message to the manufacturing execution system, wherein the first request message includes the reel identification and the station where the reel is located; and the manufacturing execution system is further configured to determine a first feedback result including the matching information of the reel and the station where the reel is located according to the first request message, and send the first feedback result to the controller, so that the controller controls the coating control system according to the first feedback result. Through the interaction between the controller and the manufacturing execution system, abnormal reels can be detected in a timely manner, reducing the probability of coating failure caused by subsequent use of abnormal reels.

[0011] In some embodiments, the controller is further configured to control the rotating mechanism to perform a reel change operation when the first feedback result includes the matching of the reel and the station where the reel is located. Performing the reel change operation only when the reel and the station where the reel is located match improves the subsequent material docking efficiency.

[0012] In some embodiments, the manufacturing execution system is further configured to determine the target station of the reel according to the reel identification, and determine whether the reel and the station where the reel is located match according to the target station of the reel and the station where the reel is located. Determining the target station of the reel through the reel information and then judging whether the reel matches the station where it is located can reduce subsequent ineffective operations of coating control due to non-matching.

[0013] In some embodiments, the first request message further includes the current product model, and the first feedback result further includes the matching information of the target product model and the current product model. Wherein, the controller is further configured to retrieve the target coating operation parameters matching the target product model, replace the coating operation parameters corresponding to the current product model with the target coating operation parameters, and control the rotating mechanism to perform a reel change operation when the first feedback result includes the matching of the reel and the station where the reel is located and the target product model does not match the current product model. Automatically adjusting the coating operation parameters when the target product model does not match the current product model can improve the accuracy of subsequent coating processing.

[0014] In some embodiments, the coating control system further includes: a tape connecting mechanism disposed at the winding station for performing a tape connecting operation on the reel; a second reader disposed at the winding station for reading an electronic tag provided on the reel located at the winding station; wherein the controller is further configured to control the tape connecting mechanism to perform a tape connecting operation on the reel according to the identification of the electronic tag by the second reader. By identifying the electronic tag by the second reader, the tape connecting operation of the reel is realized, which can reduce the problem of low tape connecting control accuracy caused by induction failure.

[0015] In some embodiments, the second reader is disposed on the frame at the winding station, and when the reel is at the winding station, the electronic tag is within the reading range of the second reader. By describing the positions of the electronic tag and the second reader, the accuracy of signal identification can be improved.

[0016] In some embodiments, the controller is further configured to: position the reel according to the identification of the electronic tag by the second reader; and control the tape connecting mechanism to perform a tape connecting operation on the reel based on the positioning information of the reel. Using the in-place signal of the electronic tag for reel positioning and tape connecting control improves the control accuracy and reduces the risk of tape connecting failure caused by dirt or light problems.

[0017] In some embodiments, an adhesive material is further provided on the side surface of the reel. The adhesive material extends along the axial direction of the reel, and the projection of the adhesive material on the end surface of the reel is at the same circumferential position as the electronic tag. Wherein, the controller is further configured to: determine the first time when the reel rotates when the second reader identifies that the electronic tag reaches the first edge of the adhesive material in contact with the web; determine the second time when the reel rotates from the first edge of the adhesive material in contact with the web to the second edge of the adhesive material in contact with the web, wherein the first edge contacts the web before the second edge; determine the third time required for the pressure roller of the tape connecting mechanism to move from the starting position of the pressure roller to the clamping position; determine the fourth time required for the cutter of the tape connecting mechanism to move from the starting position of the cutter to the cutting position; and control the telescopic times of the pressure roller and the cutter based on the first time, the second time, the third time, and the fourth time to realize the tape connecting operation of the reel. Using the identification and rotation of the electronic tag to control the telescopic times of the pressure roller and the cutter can not only improve the tightness between the web and the adhesive material, but also reduce the problem of too long trailing end, improving the tape connecting efficiency and tape connecting quality.

[0018] In some embodiments, the electronic tag includes a radio frequency identification (RFID) tag, and the first reader includes an RFID reading and writing device; or the electronic tag includes a near field communication (NFC) card, and the first reader includes an NFC card reader; or the electronic tag includes a two-dimensional code, and the first reader includes a two-dimensional code identifier.

[0019] Second aspect, the present application provides a coating control method, including: before the rotating mechanism performs a roll change operation, the controller obtains the roll identification carried by the electronic tag on the roll located at the waiting position through the first reader, and sends the roll identification to the manufacturing execution system; before the winding mechanism performs a winding operation, the manufacturing execution system generates a roll identification of the roll material to be wound onto the roll, and sends the roll identification to the controller, where the roll identification corresponds to the roll identification, and the roll material is a section of coated film; and the controller controls the winding mechanism to perform a winding operation to wind the roll material onto the roll.

[0020] In the technical solution of the embodiment of the present application, by setting an electronic tag and a reader, the reader reads the roll identification in the electronic tag, and then the controller sends the roll identification to the manufacturing execution system. The manufacturing execution system generates a roll identification corresponding to the roll material, and the roll identification corresponds to the roll identification, thereby realizing the automatic acquisition of the roll identification, eliminating the process of manually requesting the film roll number, and further reducing the probability of being unable to obtain the roll identification.

[0021] In some embodiments, the controller obtains production data related to the roll material, where the production data corresponds to the roll identification and the roll identification. By corresponding the production data with the roll identification and the roll identification, the reliability of film roll data traceability is improved.

[0022] In some embodiments, the controller sends a first request message to the manufacturing execution system, where the first request message includes the roll identification and the station where the roll is located; the manufacturing execution system determines a first feedback result including the matching information between the roll and the station where the roll is located according to the first request message, and sends the first feedback result to the controller; and the controller controls the coating control system according to the first feedback result. Through the interaction between the controller and the manufacturing execution system, abnormal rolls can be detected in a timely manner, and the probability of coating failure caused by subsequent use of abnormal rolls can be reduced.

[0023] In some embodiments, the controller controls the coating control system according to the first feedback result, including: when the first feedback result includes the matching between the roll and the station where the roll is located, the controller controls the rotating mechanism to perform a roll change operation. Performing the roll change operation only when the roll and the station where the roll is located match improves the subsequent material docking efficiency.

[0024] In some embodiments, the manufacturing execution system determines a first feedback result including the matching information between the roll and the station where the roll is located according to the first request message, including: the manufacturing execution system determines the target station of the roll according to the roll identification, and determines whether the roll matches the station where the roll is located according to the target station of the roll and the station where the roll is located. By determining the target station of the roll through the roll information and then judging whether the roll matches the station where it is located, ineffective operations caused by subsequent non-matching but coating control can be reduced.

[0025] In some embodiments, the first request message further includes the current product model, and the first feedback result further includes the matching information between the target product model and the current product model. Wherein, the controller controls the coating control system according to the first feedback result, including: when the first feedback result includes that the reel matches the station where the reel is located, and the target product model does not match the current product model, the controller retrieves the target coating operation parameters matching the target product model, replaces the coating operation parameters corresponding to the current product model with the target coating operation parameters, and controls the rotating mechanism to perform a reel change operation. When the target product model does not match the current product model, automatically adjusting the coating operation parameters can improve the accuracy of subsequent coating processing.

[0026] In some embodiments, when the controller completes the tape connection operation for the reel, it sends a second request message to the manufacturing execution system. Wherein, the second request message includes the reel identification, the station where the reel is located, and the current product model; and the manufacturing execution system generates a coil identification for the coil material according to the second request message, binds the corresponding relationship between the coil identification and the reel identification, and sends a second feedback message to the controller. Since the process of manually requesting the film roll number is omitted, the probability of forgetting to apply for and repeatedly applying for the coil identification is reduced.

[0027] In some embodiments, the controller sends the acquired production data related to the coil material to the manufacturing execution system; and the manufacturing execution system binds the corresponding relationships among the production data, the coil identification, and the reel identification. This improves the reliability of film roll data traceability and reduces the risk of data loss caused by human factors.

[0028] In some embodiments, the second feedback message includes the reel identification and the coil material status information. This facilitates the operator to timely grasp the coil material status information.

[0029] In some embodiments, the controller controls the tape connection mechanism to perform a tape connection operation on the reel according to the identification of the electronic tag located at the winding station by the second reader. By identifying the electronic tag by the second reader to implement the tape connection operation of the reel, the problem of low tape connection control accuracy caused by induction failure can be reduced.

[0030] In some embodiments, the controller controls the tape connection mechanism to perform a tape connection operation on the reel according to the identification of the electronic tag located at the winding station by the second reader, including: positioning the reel according to the identification of the electronic tag by the second reader; and based on the positioning information of the reel, controlling the tape connection mechanism to perform a tape connection operation on the reel. Using the in-place signal of the electronic tag for reel positioning and tape connection control improves the control accuracy and reduces the risk of tape connection failure caused by dirt or light problems.

[0031] In some embodiments, the electronic tag is located on the end face of the reel, and the second reader is located on the frame at the winding station. When the reel is at the winding station, the electronic tag is within the reading range of the second reader. The adhesive material is located on the side of the reel and extends along the axial direction of the reel. The projection of the adhesive material on the end face of the reel is at the same circumferential position as the electronic tag. The controller controls the tape splicing mechanism to perform a tape splicing operation on the reel, including: determining the first time when the reel rotates from the second reader recognizing the electronic tag to the first edge of the adhesive material contacting the web; determining the second time when the reel rotates from the first edge of the adhesive material contacting the web to the second edge of the adhesive material contacting the web, where the first edge contacts the web before the second edge; determining the third time required for the pressure roller of the tape splicing mechanism to move from the starting position of the pressure roller to the clamping position; determining the fourth time required for the cutter of the tape splicing mechanism to move from the starting position of the cutter to the cutting position; and controlling the telescopic time of the pressure roller and the cutter based on the first time, the second time, the third time, and the fourth time to achieve the tape splicing control of the reel. By using the recognition and rotation of the electronic tag to control the telescopic time of the pressure roller and the cutter, the tightness between the web and the adhesive material can be improved, the problem of too long trailing end can be reduced, and the tape splicing efficiency and quality can be improved.

[0032] In some embodiments, the controller determines the first time when the reel rotates by: determining the first time when the reel rotates according to the angle of the reel rotation from the second reader recognizing the electronic tag to the first edge of the adhesive material contacting the web and the time between two adjacent recognitions of the electronic tag by the second reader. Through the angle and the time for the electronic tag to rotate one week, the first time can be obtained through conversion, which is convenient for subsequent determination of the telescopic time of the pressure roller and the cutter.

[0033] In some embodiments, the controller determines the second time when the reel rotates by: determining the second time according to the time between two adjacent recognitions of the electronic tag by the second reader, the circumference of the reel, and the width information between the first edge and the second edge of the adhesive material. Through the time for the electronic tag to rotate one week, the circumference of the reel, and the width of the adhesive material, the second time can be obtained, which is convenient for subsequent determination of the telescopic time of the pressure roller and the cutter.

[0034] In some embodiments, the controller controls the extension and retraction times of the pressure roller and the cutting knife, including: after the second reader recognizes the electronic tag, after a first predetermined time, controlling the pressure roller to extend, where the first predetermined time is determined according to the difference between the first time and the third time; after the second reader recognizes the electronic tag, after a second predetermined time, controlling the cutting knife to extend, where the second predetermined time is determined according to the difference between the sum of the first time and the second time and the fourth time; and after the second reader recognizes the electronic tag, after a third predetermined time, controlling the pressure roller and the cutting knife to retract, where the third predetermined time is determined according to the sum value of the first time and the second time. By precisely controlling the extension and retraction times of the pressure roller and the cutting knife, the adhesion degree between the web material and the adhesive material on the reel can be improved, the situation of excessive trailing is reduced, and the splicing quality and efficiency are improved.

[0055] The following further describes in detail the implementation manners of the present application in conjunction with the drawings and embodiments. The detailed descriptions and drawings of the following embodiments are used to exemplarily illustrate the principle of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0056] In the description of the present application, it should be noted that unless otherwise specified, the meaning of "a plurality of" is more than two; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0057] At the same time, it should be understood that for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship.

[0058] The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present application and its application or use.

[0059] For technologies, methods, and devices known to those of ordinary skill in the relevant art, detailed discussions may not be made, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0060] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0061] It should be noted that: similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0062] To make the purpose, technical solution, and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0063] In the related art, the coating and winding process includes an empty reel waiting for loading at the waiting position, the turret rotates to drive the empty reel to rotate to the working position, and then tape splicing and winding control are performed. After the reel is full of material, the turret rotates to drive the full reel to rotate to the waiting position. After the full reel is unloaded at the waiting position, it is sent to the next process. In order to trace the data of the film roll generated, it is necessary to manually trigger to obtain the film roll number of the rolled material, but there is a situation where the application for the film roll number is forgotten.

[0064] In the embodiments of the present application, by setting up an electronic tag and a reader, the identification of the reel is realized, and then a web material identification corresponding to the web material on the reel is generated. In this way, there is a corresponding relationship among the reel, the web material, the reel identification, and the web material identification. Through the automatic acquisition of the web material identification, the probability of being unable to obtain the film roll information due to human forgetfulness can be reduced.

[0065] Figure 1 FIG. is a schematic diagram of a coating control system according to one or more embodiments. The coating control system includes a rotating mechanism 1, a winding mechanism 2, a first reader 3, a controller 4, and a manufacturing execution system 5.

[0066] The rotating mechanism 1 is used to perform a roll change operation to rotate the reel 6 located at the waiting position to the winding station. An electronic tag 7 is provided on the reel, and the electronic tag carries the reel identification of the reel.

[0067] In some embodiments, the rotating mechanism 1 is, for example, a turret. The turret drives the reel to rotate from the waiting position to the winding station to perform tape splicing and winding operations on the reel at the winding station.

[0068] In some embodiments, the electronic tag is, for example, an RFID (Radio Frequency Identification) tag. The RFID tag has the advantages of being waterproof, anti-magnetic, high-temperature resistant, long service life, data on the tag can be encrypted, larger storage data capacity, and easy change of stored information.

[0069] The RFID tag carries the reel identification of the reel. The reel identification is, for example, a reel ID (Identity document) number, and the ID number is the unique identification code of the reel.

[0070] In some embodiments, the electronic tag is, for example, an NFC (Near Field Communication) card. The NFC card has the attributes of security and convenience. The NFC tag can carry the reel identification of the reel.

[0071] In some embodiments, the electronic tag is, for example, a two-dimensional code. The two-dimensional code has the characteristics of low cost and strong versatility and can carry the reel identification of the reel.

[0072] The winding mechanism 2 is used to perform a winding operation to wind the web material onto the reel 6 at the winding station. The web material is a section of coated film. In some embodiments, the winding mechanism 2 includes a winding shaft, and through the rotation of the winding shaft, the web material is driven to wind onto the reel.

[0073] The first reader 3 is arranged at the waiting position and is used to read the electronic tag 7 provided on the reel 6 located at the waiting position.

[0074] In some embodiments, when the electronic tag is an RFID tag, the first reader includes an RFID reading and writing device, which is capable of reading the reel identification carried by the RFID tag.

[0075] In some embodiments, when the electronic tag is an NFC card, the first reader includes an NFC card reader, which is capable of reading the reel identification carried by the NFC card.

[0076] In some embodiments, when the electronic tag is a two-dimensional code, the first reader includes a two-dimensional code recognizer, which is capable of reading the reel identification carried by the two-dimensional code.

[0077] The controller 4 is electrically connected to the first reader 3 and is configured to obtain the reel identification from the first reader 3 before the rewinding mechanism 1 performs a rewinding operation and send it to the manufacturing execution system 5.

[0078] In some embodiments, the controller is, for example, a PLC (Programmable Logic Controller). The PLC can obtain the reel ID from the first reader. For example, after the first reader reads the reel ID, it sends it to the PLC. Those skilled in the art should understand that here the PLC is only for illustration, and the function of the controller can also be implemented by a structure composed of integrated circuits, related components, etc.

[0079] The manufacturing execution system 5 is electrically connected to the controller 4 and is configured to generate a coil material identification corresponding to the coil material before the winding mechanism 2 performs a winding operation, wherein the reel identification and the coil material identification correspond to each other.

[0080] In some embodiments, the coil material identification is information for identifying the coil material, that is, the identification number of the coil material, for example, the film roll number of the coil material.

[0081] In some embodiments, the MES determines whether the reel is available. If the reel is available, it generates a film roll number and binds the film roll number to the reel identification, that is, realizes the binding of the film roll number and the reel.

[0082] In some embodiments, the MES stores the corresponding relationship between the coil material identification and the reel identification, which is convenient for subsequent tracing of materials. Through this corresponding relationship, the relevant information of the coil material can be obtained.

[0083] In some embodiments, after the MES generates the coil material identification corresponding to the coil material, it outputs the coil material identification and the reel identification to an external memory. By storing the corresponding relationship between the coil material identification and the reel identification through this memory, the storage space of the MES itself can be reduced.

[0084] In the above embodiments, by providing an electronic tag carrying a reel identifier on the reel, after the first reader reads the reel identifier carried by the electronic tag, it is sent to the manufacturing execution system through the controller, and the manufacturing execution system generates a coil identifier corresponding to the reel identifier, realizing the automatic acquisition of the coil identifier. Since there is no need for a manual process to request the coil identifier, the probability of not being able to obtain the coil identifier is reduced.

[0085] In some embodiments, one reel identifier corresponds to one coil identifier, which can also reduce the situation where multiple coil identifiers are repeatedly applied for, resulting in the inability to determine which coil identifier the subsequent production data matches.

[0086] In some embodiments of the present application, such as Figure 2A and 2B As shown, the electronic tag 7 is located at the end face of the reel 6. Since the coil 61 is wound around the reel 6, the electronic tag is set at the end face of the reel, which facilitates the first reader to more conveniently and quickly identify the electronic tag.

[0087] The first reader 3 is set on the frame 31 at the waiting position of the coater, and when the reel is at the waiting position, the electronic tag is within the reading range of the first reader. There is a certain distance between the frame and the reel. Setting the electronic tag at the end face of the reel and setting the first reader on the frame is more convenient to install compared to other positions.

[0088] In this embodiment, since the electronic tag is within the reading range of the first reader, the first reader can accurately and quickly identify the reel ID in the electronic tag. In addition, manually triggering the application for the film roll number may cause repeated applications. In this embodiment, by providing the electronic tag and the reader, the process of manually requesting the film roll number can be omitted subsequently. Therefore, the probability of repeatedly applying for the film roll number is also reduced.

[0089] In some other embodiments of the present application, the controller 4 is further configured to acquire production data related to the coil, wherein the production data corresponds to the reel identifier and the coil identifier.

[0090] During the production process of the coil, there will be some processing process parameters, such as weight data, drying data, etc., which are convenient for subsequent quality traceability. Therefore, it is necessary to save the production data.

[0091] For example, after production is completed, the PLC sends the production data to the MES, and the MES saves the corresponding relationship between the production data, the reel identifier, and the coil identifier. In the next process, the reel identifier is obtained through the reader, and then according to this corresponding relationship, the coil identifier and the production data corresponding to the reel identifier are found, thereby improving the reliability of film roll data traceability and reducing the risk of data loss caused by human factors.

[0092] In some embodiments, the next process includes operations such as rolling and cutting. For example, according to production data, the coiled material is rolled into a material with a consistent thickness, and then a cutting operation is performed to delete invalid materials, etc.

[0093] For another example, the PLC sends the production data to other external memories, and the memories store the corresponding relationships between the production data, the reel identification, and the coiled material identification. When it is necessary to trace the coiled material data, the reel identification is obtained through a reader, and then the corresponding coiled material identification and production data are called from the memories, which not only improves the reliability of the film reel data traceability but also reduces the storage space pressure of the MES.

[0094] In addition, in the above embodiments, since there is a corresponding relationship between the production data, the reel identification, and the coiled material identification, it is not necessary to print and paste a paper shipping label onto the film reel, reducing the risk of loss of film reel data caused by the shipping label not being firmly pasted and falling off.

[0095] In some embodiments of the present application, the controller 4 is further configured to send a first request message to the manufacturing execution system 5, where the first request message includes the reel identification and the station where the reel is located; the manufacturing execution system 5 is further configured to determine a first feedback result including the matching information between the reel and the station where the reel is located according to the first request message, and send the first feedback result to the controller 4 so that the controller 4 controls the coating control system according to the first feedback result.

[0096] In this embodiment, through the interaction between the controller and the manufacturing execution system, the manufacturing execution system determines the matching information between the reel and the station, and feeds back the matching information to the controller. The controller performs coating control according to the matching information, which can improve the material docking process of coating and subsequent processes, improve the docking efficiency, and reduce the labor cost caused by manual judgment.

[0097] In some embodiments, the manufacturing execution system 5 is further configured to determine the target station of the reel according to the reel identification, and determine whether the reel matches the station where the reel is located according to the target station of the reel and the station where the reel is located.

[0098] For example, when an empty reel is loaded at the waiting position, the PLC sends the reel ID and the station information to the MES, and the MES determines whether the target station of the reel matches the station where the reel is located. If the target station of the reel matches the station where the reel is located, it means that the reel is the correct reel; if the target station of the reel does not match the station where the reel is located, it means that the reel is an abnormal reel. By automatically identifying the abnormal reel, the cost of manual identification can be reduced, and the abnormal reel can be identified in time, reducing the probability of errors in subsequent processes.

[0099] In some embodiments, the station information is, for example, the machine number.

[0100] In some embodiments, the controller 4 is further configured to issue an alarm message when the first feedback result includes that the reel does not match the station where the reel is located.

[0101] For example, when the MES identifies that the reel is an abnormal reel, it feeds back the station information of the reel to the PLC, and the PLC outputs an alarm message. For example, it outputs a prompt of "Please replace the correct reel", which is convenient for the operator to replace the equipment in time, and reduces the risk of equipment damage or material scrapping caused by subsequent incorrect processes such as reel change and winding with the wrong reel.

[0102] In some embodiments, the controller 4 is further configured to control the rotating mechanism to perform a reel change operation when the first feedback result includes that the reel matches the station where the reel is located.

[0103] For example, when the manufacturing execution system identifies that the target station of the reel matches the station where the reel is located, it feeds back the station information of the reel to the PLC, and the PLC determines that the reel is the correct reel, and then waits for the reel change operation, providing a basis for the execution of subsequent correct processes.

[0104] In some embodiments of the present application, the controller 4 is further configured to send a first request message to the manufacturing execution system 5, and the first request message includes a reel identifier, the station where the reel is located, and the current product model. The manufacturing execution system 5 is further configured to determine a first feedback result including the matching information between the reel and the station where the reel is located and the matching information between the target product model and the current product model according to the first request message, and send the first feedback result to the controller 4 so that the controller 4 controls the coating control system according to the first feedback result.

[0105] This embodiment can realize flexible control such as automatic equipment type change and automatic processing of abnormal reels by identifying reel information, and further can improve the material docking process of coating and subsequent processes, and improve the docking efficiency.

[0106] In some embodiments, the manufacturing execution system 5 is further configured to identify the target product model according to the reel identifier when the reel matches the station where the reel is located, and determine whether the target product model matches the current product model.

[0107] For example, the PLC sends the reel ID, station information, and the current product model to the MES, and the MES determines whether the target station of the reel matches the station where the reel is located. If the target station of the reel matches the station where the reel is located, it further determines whether the target product model corresponding to the reel matches the current product model. This embodiment realizes the acquisition of the product information produced by the coater. When the target product model corresponding to the reel matches the current product model, the reel is marked as a correct reel. When the target product model corresponding to the reel does not match the current product model, the reel is marked as a changeover reel, that is, the equipment needs to be changed over, which facilitates subsequent automatic changeover by the PLC and adjustment of equipment parameters.

[0108] In some embodiments, the controller 4 is further configured to, when the first feedback result includes that the reel matches the station where the reel is located and the target product model does not match the current product model, retrieve the target coating operation parameters matching the target product model, replace the coating operation parameters corresponding to the current product model with the target coating operation parameters, and control the rotating mechanism to perform a reel change operation.

[0109] For example, when the PLC identifies that the reel is marked as a changeover reel, it retrieves the target coating operation parameters matching the target product model. After performing parameter switching, it further performs a changeover action, that is, replaces some actuators of the coater or changes the positions of some actuators of the coater. For example, the camera corresponding to product model A takes pictures at position M, while the camera corresponding to product model B takes pictures at position N, then the camera position needs to be changed. After the changeover is completed, the coater continues and can wait for the start of the reel change process later.

[0110] In the above embodiment, by identifying the reel information, when it is determined that the target product model does not match the current product model, automatic changeover and automatic adjustment of equipment parameters are realized, reducing the cost of manual misjudgment and the problem of material docking failure caused by inconsistent equipment parameter models.

[0111] In some embodiments, the controller 4 is further configured to, when the first feedback result includes that the reel matches the station where the reel is located and the target product model matches the current product model, control the rotating mechanism to perform a reel change operation. In this embodiment, by judging the reel station and the product model, the reel change operation is only performed when the reel is a correct reel, reducing the risk of incorrect materials in subsequent processes caused by incorrect reels or product models.

[0112] In some other embodiments of the present application, the controller 4 is further configured to send a second request message to the manufacturing execution system 5 when the operation of splicing the web onto the reel is completed. The second request message includes the reel identification, the station where the reel is located, and the current product model. The manufacturing execution system 5 is further configured to generate a web identification for the web material according to the second request message, bind the corresponding relationship between the web identification and the reel identification, and send a second feedback message to the controller.

[0113] For example, after the reel change and splicing operation are completed, the PLC sends the reel ID, the machine station number, and the current product model to the MES to request the generation of a new web roll number. The MES generates a new web roll number, binds the web roll number to the reel ID, ends the data recording and processing of the previous web roll, sets the target station to the station where the reel is located, and feeds back the reel ID and the web material status information to the PLC. The web material status information may include, for example, whether the web material is in production or has been produced. The PLC can timely know the web material status.

[0114] In the above embodiments, the binding process of the web material information is interacted between the controller and the manufacturing execution system, and the process of manually requesting the web roll number is omitted, which can improve the degree of equipment automation and reduce the risk of not applying for the web identification or repeatedly applying for the web identification.

[0115] In the related art, when manually requesting the web roll number of the web material and after the production is completed, a shipping label is printed and pasted on the web roll. There is a situation where the shipping label is not firmly pasted, causing the shipping label to fall off, which easily leads to the loss of the web roll data.

[0116] In some other embodiments of the present application, the controller 4 is further configured to send the obtained production data related to the web material to the manufacturing execution system 5. The manufacturing execution system 5 is further configured to bind the corresponding relationship among the production data, the web identification, and the reel identification.

[0117] For example, during the production process, the PLC records the production data corresponding to the web roll number in real time. The PLC can save the production data or not, but sends the production data, the corresponding web roll number, the reel ID, etc. to the MES, and the MES saves the corresponding relationship among the production data, the web roll number, and the reel ID. When it is necessary to trace the web roll data after the production is completed, the MES looks up the corresponding production data and web roll number through the reel ID. Since there is no need for steps such as manually printing and pasting the shipping label, the risk of web roll data loss is greatly reduced, and even the risks of equipment damage and material waste caused by processing the wrong web roll in the subsequent processes are reduced. In addition, since the application of the web roll number and the binding of the production data are realized through the interaction between the controller and the manufacturing execution system, the risk that a reel applies for multiple web roll numbers and the production data cannot be determined to match which web roll number is reduced.

[0118] Figure 3 A schematic diagram of a coating control system according to one or more embodiments. In this embodiment, the coating control system further includes a tape splicing mechanism 8 and a second reader 9. The tape splicing mechanism 8 is arranged at the winding station and is used for splicing the web on the reel 6. The second reader 9 is arranged at the winding station and is used for reading the electronic tag 7 provided on the reel 6 located at the winding station. Wherein, the controller 4 is further configured to control the tape splicing mechanism 8 to splice the reel according to the identification of the electronic tag by the second reader 9.

[0119] In the related art, during the tape splicing process, color marks and color mark sensors are used to achieve the positioning of the reel. It is easy to cause problems such as the failure of the color mark sensor to sense due to color mark contamination. In the above embodiment, the tape splicing control is carried out by using the identification of the electronic tag by the reader, which can improve the tape splicing success rate and the tape splicing quality, and reduce the risk of tape splicing failure caused by color mark dirt and light problems.

[0120] In some embodiments, the tape splicing structure includes components for tape splicing operations such as a pressure roller and a cutter. The pressure roller, cutter, etc. are located at one end of the swing arm mechanism close to the reel. The pressure roller is used to press and bond the web to the adhesive material. The cutter is used to cut off the web on the current reel from the web on the previous reel.

[0121] In some embodiments, the second reader 9 is arranged on the frame at the winding station. When the reel is at the winding station, the electronic tag 7 is within the reading range of the second reader 9, so that the second reader can identify the electronic tag and realize the positioning of the reel. In addition, setting the second reader on the frame is easier to install compared to installing it in other positions.

[0122] In some embodiments, the controller 4 is further configured to position the reel according to the identification of the electronic tag by the second reader 9, and control the tape splicing mechanism to splice the reel based on the positioning information of the reel.

[0123] In this embodiment, since the position of the reader remains unchanged and the relative position of the electronic tag on the reel remains unchanged, the electronic tag rotates with the reel during the rotation of the reel. When the reader detects the electronic tag, it means that the reel has rotated to the predetermined position, and this moment can be used as the initial moment of the tape splicing control timing sequence. By calculating the specific moment for performing the tape splicing, the precise control of the tape splicing can be realized. The tape splicing process will be introduced in detail below.

[0124] In some embodiments, an adhesive material is further provided on the side surface of the reel. The adhesive material is, for example, double-sided tape. The adhesive material extends along the axial direction of the reel, and the projection of the adhesive material on the end surface of the reel is in the same circumferential position as the electronic tag, that is, the double-sided tape is aligned with the position of the electronic tag and is pasted on the reel. The double-sided tape is, for example, strip-shaped and has a first edge and a second edge. The first edge contacts the web earlier than the second edge.

[0125] The controller determines the first time when the second reader recognizes that the electronic tag reaches the first edge of the adhesive material in contact with the web, and the web rotates. As Figure 4A-4B shown, the second reader 9 recognizes the electronic tag 7. The electronic tag 7 and the adhesive material rotate counterclockwise along with the web. After the first time, the first edge of the adhesive material needs to be adhered to the web.

[0126] For example, according to the angle of the web rotation when the second reader recognizes that the electronic tag reaches the first edge of the adhesive material in contact with the web, and the time between two adjacent recognitions of the electronic tag by the second reader, the first time of the web rotation is determined. For example, the time between two adjacent recognitions of the electronic tag by the second reader is T, that is, the time for the web to rotate one week is T. The angle of the web rotation when the second reader recognizes that the electronic tag reaches the first edge of the adhesive material in contact with the web is C. One circle of the web rotation is 360 degrees. Then the first time is the ratio of the angle C to 360 multiplied by the time T, that is, the first time Tc = (C / 360)*T. If one circle of the web rotation is represented by 2π, then the first time Tc = (C / 2π)*T, where the angle C is also represented in radians.

[0127] Further, the controller determines the second time when the web rotates from the first edge of the adhesive material in contact with the web to the second edge of the adhesive material in contact with the web. For example, according to the time between two adjacent recognitions of the electronic tag by the second reader, the circumference of the web, and the width information between the first edge and the second edge of the adhesive material, the second time is determined.

[0128] For example, the time between two adjacent recognitions of the electronic tag by the second reader is T, the circumference of the web is D, and the width of the adhesive material is L. Then the second time is the product of the ratio of the width L to the circumference D and the time T, that is, the second time Tj = (L / D)*T.

[0129] Further, the controller determines the third time required for the pressure roller 81 of the tape splicing mechanism to move from the starting position of the pressure roller to the pressing position, and determines the fourth time required for the cutter 82 of the tape splicing mechanism to move from the starting position of the cutter to the cutting position. The starting position of the pressure roller is the position close to the web for waiting, and the pressing position is the position when the pressure roller pushes the web against the web. The starting position of the cutter is the position waiting to cut the web, and the cutting position is the position when cutting the web. For example, by means of stopwatch measurement, the third time Ty and the fourth time Tq can be determined. Figure 4A-4B It shows that the pressure roller 81 is at the starting position, Figure 4C It shows that the pressure roller 81 moves to the pressing position along with the swing arm mechanism 83. Figure 4D It shows that the cutter 82 moves to the cutting position along with the swing arm mechanism 83.

[0130] In some embodiments, the controller controls the extension and retraction of the pressure roller by controlling the cylinder action of the pressure roller, and controls the extension and retraction of the cutting knife by controlling the cylinder action of the cutting knife.

[0131] Based on the first time, the second time, the third time, and the fourth time, the controller controls the extension and retraction times of the pressure roller and the cutting knife to achieve the tape connecting operation for the web.

[0132] In the above embodiments, by controlling the extension and retraction times of the pressure roller and the cutting knife, the sufficient adhesion between the web material and the adhesive material can be improved, thereby improving the success rate and quality of automatic tape connection.

[0133] Next, taking Figure 5 as an example, the specific timing control of the pressure roller and the cutting knife will be described.

[0134] Figure 5 In Figure 5 , the zero point moment T0 is the moment when the second reader recognizes the electronic tag. After Tc, the first edge of the adhesive material contacts the web. After the first predetermined time T1 from when the second reader recognizes the electronic tag, the pressure roller is controlled to extend. After the second predetermined time T2 from when the second reader recognizes the electronic tag, the cutting knife is controlled to extend. After the third predetermined time T3 from when the second reader recognizes the electronic tag, the pressure roller and the cutting knife are controlled to retract.

[0135] The first predetermined time T1 is determined according to the difference between the first time and the third time. The second predetermined time is determined according to the difference between the sum of the first time and the second time and the fourth time. The third predetermined time is determined according to the sum value of the first time and the second time. For example, T1 = Tc - Ty, T2 = Tc + Tj - Tq, T3 = Tc + Tj.

[0136] In the above embodiments, by precisely controlling the pressure roller, the web material can be fully adhered to the adhesive material on the reel, reducing the probability of tape breakage due to poor adhesion. Moreover, by precisely controlling the extension and retraction of the cutting knife, when the web tail is too long, the tape connection quality can be improved.

[0137] Figure 6 is a schematic diagram of a coating control method according to one or more embodiments. This embodiment is applied to the winding process. As Figure 7A shown, in the coating and winding process, the empty reel B waits for loading at the waiting position. The reel A at the winding station is driven to rotate by a winding mechanism such as a winding shaft, so that the web is wound onto the reel A at the winding station until the reel A is full. The parallel arrows represent the incoming material direction, and the arrow above the reel A represents the rotation direction of the winding shaft. As Figure 7BAs shown, during the roll change process, rotating mechanisms such as the turret rotate, driving the empty reel B to rotate from the waiting position to the winding working position. At this time, the full reel A is at the waiting position, and the arrow between reel A and reel B indicates the rotation direction of the turret. After the roll change process is completed, as Figure 7C shown, the tape connecting process is executed. This control process will be introduced in detail later. Among them, the upward arrow indicates the movement direction of the swing arm mechanism. After the tape connecting process is completed, as Figure 7D shown, the winding process is executed until the empty reel B is full. Among them, the downward arrow indicates the movement direction of the swing arm mechanism. Subsequently, the turret rotates, driving the fully loaded reel to rotate to the waiting position. After the fully loaded reel is unloaded, it is sent to the next process. The coating control method will be introduced in detail below.

[0138] In step 610, before the rotating mechanism performs the roll change operation, the controller obtains the reel identification of the reel carried by the electronic tag on the reel at the waiting position through the first reader, and sends the reel identification to the manufacturing execution system.

[0139] For example, when the reel is loaded, after the loading is completed, the empty reel rotates, and the RFID reading and writing device recognizes the RFID tag, then reads the reel ID in the RFID tag. The RFID reading and writing device transmits the reel ID to the PLC, and the PLC sends the reel ID to the MES. Subsequently, the PLC will also control the execution of operations such as roll change and tape connection.

[0140] In step 620, before the winding mechanism performs the winding operation, the manufacturing execution system generates a roll material identification corresponding to the roll material to be wound onto the reel, and sends the roll material identification to the controller, where the roll material identification corresponds to the reel identification, and the roll material is a section of coated film.

[0141] For example, after the PLC finishes the tape connection control, it sends a request to the MES to generate a film roll number. After receiving the request, the MES generates the film roll number. After binding the film roll number and the reel ID, it sends the film roll number to the controller.

[0142] In step 630, the controller controls the winding mechanism to perform the winding operation to wind the roll material onto the reel.

[0143] In the above embodiment, the controller reads the reel identification in the electronic tag through the first reader and sends the reel identification to the manufacturing execution system. The manufacturing execution system generates the roll material identification, and the roll material identification has a corresponding relationship with the reel identification. Since there is no need for manual request of the roll material identification, but the controller and the manufacturing execution system generate the roll material identification through interaction, the probability of forgetting to apply or repeatedly applying for the roll material identification is reduced.

[0144] In some embodiments of the present application, the controller obtains production data related to the coiled material, where the production data corresponds to the reel identification and the coiled material identification.

[0145] For example, when the PLC receives the film reel number sent by the MES, it controls the coater to perform the winding operation. After the production is completed, it records the production data and sends the production data to the MES, and the MES saves the correspondence between the production data, the reel identification, and the coiled material identification.

[0146] In subsequent processes, the reel identification is read through the RFID reading and writing device, and then according to the corresponding relationship, the coiled material identification and the production data are found in the MES, which improves the reliability of film reel data traceability. In addition, since there is no need to print and paste the shipping label, the risk of film reel data loss is greatly reduced, and further reduces the risks of equipment damage and material scrap caused by processing the wrong film reel in the subsequent process.

[0147] Figure 8 It is a schematic diagram of a coating control method according to one or more embodiments.

[0148] In step 810, the controller sends a first request message to the manufacturing execution system, where the first request message includes the reel identification and the station where the reel is located.

[0149] In some embodiments, the first request message may further include the current product model for the MES to perform product model comparison.

[0150] In some embodiments, the PLC sends a message T10 to the MES, and the message T10 contains information such as the message name, machine number, current product model, and reel ID.

[0151] In step 820, the manufacturing execution system determines a first feedback result including the matching information between the reel and the station where the reel is located according to the first request message, and sends the first feedback result to the controller.

[0152] In some embodiments, the manufacturing execution system determines the target station of the reel according to the reel identification, and determines whether the reel matches the station where the reel is located according to the target station of the reel and the station where the reel is located.

[0153] For example, the machine number where the reel is located is 001. By the reel ID, it is determined that the target machine number of the reel is 002, which means that the reel does not match the station where the reel is located. If the target machine number of the reel is also 001, it means that the reel matches the station where the reel is located. In this embodiment, by determining whether the reel matches through the MES, abnormal reels can be detected in time, reducing risks such as material scrap caused by using abnormal reels for subsequent winding work.

[0154] In some embodiments, when the manufacturing execution system determines that the reel matches the station where coating is performed, it identifies the target product model based on the reel identification and determines whether the target product model matches the current product model.

[0155] For example, if the MES identifies the product model to be produced as 1001 based on the reel ID, but the current product model generated by the coater is 1002, it indicates that the target product model does not match the current product model, thus enabling timely identification of abnormal products and reducing the probability of producing non-conforming products in subsequent production.

[0156] In some embodiments, after the MES generates a feedback result, it sends feedback message T20 to the PLC. This message T20 includes information such as the message name, reel ID, whether the reel belongs to this station, and the target product model.

[0157] In step 830, the controller controls the coating control system based on the first feedback result.

[0158] In this embodiment, the controller controls the coating control system according to the feedback result of the manufacturing execution system, which can improve the subsequent material docking efficiency and the degree of equipment automation.

[0159] In some embodiments, when the first feedback result indicates that the reel does not match the station where the reel is located, the controller issues an alarm message to promptly remind the staff to replace the reel.

[0160] In some embodiments, when the first feedback result indicates that the reel matches the station where the reel is located, the controller controls the rotating mechanism to perform a reel change operation to improve the subsequent material docking efficiency.

[0161] In some embodiments, when the first feedback result indicates that the reel matches the station where the reel is located and the target product model does not match the current product model, the controller retrieves the target coating operation parameters that match the target product model, replaces the coating operation parameters corresponding to the current product model with the target coating operation parameters, and controls the rotating mechanism to perform a reel change operation, thereby realizing automatic type change and automatic adjustment of equipment parameters.

[0162] In some embodiments, when the first feedback result indicates that the reel matches the station where coating is performed and the target product model matches the current product model, the controller controls the rotating mechanism to perform a reel change operation to reduce the risk of subsequent coating operation failure caused by abnormal film reels.

[0163] Figure 9 It is a schematic diagram of a coating control method according to one or more embodiments.

[0164] In step 910, when the controller finishes the operation of connecting the tape to the reel, it sends a second request message to the manufacturing execution system, where the second request message includes the reel identification, the station where the reel is located, and the current product model.

[0165] In some embodiments, the PLC sends a message T30 to the MES, and the message T30 includes the message name, the machine number, the current product model, and the reel ID. In this embodiment, the reel number is requested by sending the message T30.

[0166] In step 920, the manufacturing execution system generates a coil identification of the coil material according to the second request message, binds the corresponding relationship between the coil identification and the reel identification, and sends a second feedback message to the controller.

[0167] In some embodiments, the MES feeds back a message T40 to the PLC, and the message T40 includes the message name, the reel ID, and the coil status information.

[0168] In the above embodiments, when the tape connection is completed, the controller actively requests the manufacturing execution system to obtain the coil identification. The manufacturing execution system binds the reel identification and the coil identification, which improves the degree of equipment automation. Moreover, since the process of manually requesting the coil number is omitted, the probability of forgetting to apply and repeatedly applying for the coil identification is reduced.

[0169] In some other embodiments of the present application, the controller sends the obtained production data related to the coil material to the manufacturing execution system, and the manufacturing execution system binds the corresponding relationship among the production data, the coil identification, and the reel identification.

[0170] For example, the PLC sends the production data to the MES, and the MES saves the corresponding relationship among the production data, the coil identification, and the reel identification, which improves the reliability of coil data traceability and reduces the risk of data loss caused by human factors.

[0171] In some other embodiments of the present application, the coil changing process is improved. The controller controls the tape connection mechanism to perform the tape connection operation on the reel according to the identification of the electronic tag located at the winding station by the second reader.

[0172] In this embodiment, the electronic tag replaces the color mark, and the second reader replaces the color mark sensor to control the tape connection mechanism to perform the tape connection control on the reel, which can reduce the problem of tape connection failure caused by abnormal situations such as the color mark being dirty and the color mark sensor failing to sense.

[0173] In some embodiments, the reel is positioned according to the identification of the electronic tag by the second reader, and based on the positioning information of the reel, the tape connection mechanism is controlled to perform the tape connection operation on the reel. In this embodiment, the in-place signal of the electronic tag is used for reel positioning and tape connection control, which can improve the control efficiency.

[0174] Figure 10 Schematic diagram of a coating control method according to one or more embodiments.

[0175] In step 1010, determine the first time when the second reader recognizes that the first edge of the electronic tag to the adhesive material contacts the web and the web rotates.

[0176] In some embodiments, according to the angle at which the second reader recognizes that the first edge of the electronic tag to the adhesive material contacts the web and the web rotates, and the time between two adjacent recognitions of the electronic tag by the second reader, determine the first time when the web rotates.

[0177] In step 1020, determine the second time when the web rotates from the contact of the first edge of the adhesive material with the web to the contact of the second edge of the adhesive material with the web, where the first edge contacts the web before the second edge.

[0178] In some embodiments, according to the time between two adjacent recognitions of the electronic tag by the second reader, the circumference of the web, and the width information between the first edge and the second edge of the adhesive material, determine the second time.

[0179] In step 1030, determine the third time required for the pressure roller of the tape splicing mechanism to move from the starting position of the pressure roller to the clamping position.

[0180] For example, by using a stopwatch measurement to determine the time required for the pressure roller to move from the starting position of the pressure roller to the clamping position.

[0181] In step 1040, determine the fourth time required for the cutter of the tape splicing mechanism to move from the starting position of the cutter to the cutting position.

[0182] For example, by using a stopwatch measurement to determine the time required for the cutter to move from the starting position of the cutter to the cutting position.

[0183] In step 1050, based on the first time, the second time, the third time, and the fourth time, control the telescopic time of the pressure roller and the cutter to achieve the tape splicing control of the web.

[0184] In some embodiments, according to the difference between the first time and the third time, determine the first predetermined time from when the second reader recognizes the electronic tag to when the pressure roller extends.

[0185] According to the difference between the sum of the first time and the second time and the fourth time, determine the second predetermined time from when the second reader recognizes the electronic tag to when the cutter extends.

[0186] According to the sum value of the first time and the second time, determine the third predetermined time from when the second reader recognizes the electronic tag to when the pressure roller and the cutter retract.

[0187] In the above embodiments, the tape splicing control is achieved by detecting the signal of the electronic tag. On the one hand, the bonding tightness between the coil material and the adhesive material is improved. On the other hand, the remaining tail of the coil material can be reduced, and the success rate and quality of automatic tape splicing are improved.

[0188] Next, a specific embodiment will be taken as an example to introduce the winding process of the present application, as Figure 11 shown.

[0189] In step 1110, the PLC controls the loading of the reel. An RFID tag is provided on the reel, and the reel ID is carried in the RFID tag.

[0190] In step 1120, after the loading is completed, the PLC controls the rotation of the empty reel.

[0191] In step 1130, the first RFID reading and writing device identifies the RFID tag and reads the reel ID in the RFID tag.

[0192] In step 1140, the PLC sends the reel ID, the machine number, and the current product model to the MES. For example, a message is sent through message T10.

[0193] In step 1150, the MES determines whether the target machine number of the reel matches the current machine number. If it matches, step 1160 is executed; otherwise, step 1170 is executed.

[0194] In step 1160, the MES determines whether the current product model matches the target product model. If it matches, step 1161 is executed; otherwise, step 1162 is executed.

[0195] In step 1161, the MES marks the reel as the correct reel.

[0196] In step 1162, the MES marks the reel as a changeover reel.

[0197] In step 1170, the MES marks the reel as an abnormal reel.

[0198] In step 1180, the MES feeds back the judgment result to the PLC. For example, a message is sent through message T20.

[0199] In step 1190, when the feedback from the MES is successful, the PLC identifies the feedback result.

[0200] In step 11100, when the feedback result is that the reel is an abnormal reel, the PLC outputs an alarm message. For example, a voice prompt to replace the correct reel or a text prompt is output.

[0201] In step 11110, when the feedback result indicates that the reel is a changeover reel, the PLC retrieves the target model parameters.

[0202] In step 11120, the PLC replaces the current model parameters with the target model parameters.

[0203] In step 11130, the equipment is changed over.

[0204] In step 11131, after the changeover operation is completed, it is prompted that the equipment is ready, and then step 11140 is executed next.

[0205] In step 11140, when the feedback result indicates that the reel is the correct reel, the PLC waits for the coil change start.

[0206] In step 11141, the PLC controls the coil change operation.

[0207] In step 11150, after the coil change operation is executed, the PLC controls the execution of the reel splicing action.

[0208] In step 11160, after the reel splicing action is completed, the PLC sends a request for obtaining the film roll number to the MES. For example, a message is sent through the message T30.

[0209] In step 11170, the MES generates the film roll number.

[0210] In step 11180, the MES binds the film roll number with the reel ID and stops recording data for the previous film roll number.

[0211] In step 11190, the MES feeds back to the PLC to transmit the film roll number to the PLC. For example, a message is sent through the message T40.

[0212] In step 11200, the PLC obtains the production data and sends the production data to the MES.

[0213] In step 11210, the MES binds the production data with the film roll number.

[0214] In the above embodiment, steps such as manually requesting film roll information and pasting shipping labels are cancelled. Instead, the PLC automatically requests the film roll number from the MES, and the MES binds the corresponding relationship between the production data and the film roll number, improving the reliability of film roll information traceability. In addition, by identifying the reel information, automatic changeover, automatic adjustment of equipment parameters, and automatic processing of abnormal reels or film rolls are also realized, reducing the labor cost and improving the equipment automation level and flexible processing ability.
