[0025] Figure 1 The flowchart of a control method for a manufacturing system according to an embodiment of the present application is schematically shown. Figure 1 As shown, an embodiment of the present application provides a control method for a manufacturing system, wherein the manufacturing system includes a controller, a management module, and multiple workstations, each workstation being used to execute a processing procedure for a material to be processed, and the control method is applied to the management module, wherein for each workstation, the method may include the following steps.

[0026] A manufacturing system refers to a physical organizational system constructed to achieve a predetermined manufacturing purpose. It is an organic whole with specific functions composed of manufacturing processes, hardware, software and related personnel. Specifically, a manufacturing system can refer to a PCR manufacturing system, that is, a manufacturing system for a real-time fluorescence quantitative analysis instrument. For a PCR manufacturing system, its workstations may include a loading station, an optical pressure sensor installation station, a filter installation station, a lens installation station, a module internal visual inspection station, a capping and screwing station, a PD board installation station, a gas shear tinning station, an optical power detection station and a marking station, etc.

[0027] The management module may refer to the MES system, i.e. the Manufacturing Execution System, which is a production information management module for the execution layer of the workshop of a manufacturing enterprise. It aims to optimize the entire production process from order placement to product completion through information transmission, and acquire and manage multiple elements of the production site in real time, such as materials, personnel, equipment and inventory, so as to improve production efficiency, reduce costs and ensure product quality. The MES system can collect production data from the production process of the PCR module, including the preset flag information stored in the first data area of ​​the controller, and manage and analyze the preset flag information to determine whether to perform entry and exit operations, and provide a basis for the optimization of the production process. Through the analysis of production data, bottlenecks in the production process can be found, providing direction for the improvement of the production process.

[0028] S102, acquiring information of a first data area in the controller in real time, where the first data area includes a preset flag bit.

[0029] It can be understood that the first data area of ​​the controller refers to an area for storing data, which can record various flag states during the execution of the program, and can also perform read and write operations. The preset flag bit is a variable that represents a certain state or condition. Specifically, the preset flag bit includes an entry mark and an exit mark. The entry mark can be used to identify the entry situation of the processing station for the material to be processed, and the exit mark can be the exit situation of the processing station for the material to be processed. The preset mark bit can be a Byte word in the first data area. The controller can rewrite the preset flag bit according to the processing situation of the workstation for the material to be processed. In addition, the preset mark bit can also be a management module for read and write operations.

[0030] S104: Determine the entry and exit request of the workstation according to the preset flag.

[0031] It can be understood that the inbound and outbound requests include inbound requests and outbound requests from the workstation for the materials to be processed.

[0032] In an embodiment of the present application, the preset flag bits include an entry mark and an exit mark, and determining the entry and exit requests of the workstation according to the preset flag bits includes: when the entry mark is a first mark, determining the entry and exit requests as entry requests, wherein the first mark is when the material to be processed arrives at the workstation, the controller modifies the entry mark to the first mark; when the exit mark is a second mark, determining the entry and exit requests as exit requests, wherein the second mark is when the material to be processed in the workstation completes the processing procedure, the controller modifies the entry mark to the second mark.

[0033] Specifically, when the material to be processed arrives at the workstation, it is fed back to the controller through in-situ detection, and the controller modifies the entry mark of the first data area to the first mark. When the management module obtains in real time that the entry mark is the first mark, it determines that the entry and exit requests of the workstation are entry requests. An entry request refers to a request for the material to be processed to enter the workstation to perform a processing procedure. When the workstation completes the processing procedure for the material to be processed, the controller modifies the exit mark of the second data area to the first mark. When the management module obtains in real time that the exit mark is the second mark, it determines that the entry and exit request is an exit request. An exit request refers to a request that the material to be processed has completed the process operation of the current workstation and needs to enter the next workstation or leave the manufacturing system.

[0034] S106, executing a corresponding entry operation or exit operation according to the entry and exit request.

[0035] In an embodiment of the present application, executing a corresponding entry operation or exit operation according to an entry / exit request includes: reading material processing information in a controller, the material processing information is obtained when the material to be processed arrives at the workstation, the controller controls the read-write device in the workstation to read the read-write tag of the material to be processed; determining whether the workstation executes the corresponding entry operation or exit operation for the entry / exit request according to the entry / exit request and the material processing information.

[0036] The readable and writable tag can be an electronic tag of Radio Frequency Identification (RFID). The read-write device can identify the readable and writable tag and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and the specific target. When it is determined that the material to be processed has arrived at the workstation, the controller can control the read-write device installed at the workstation to read the material processing information of the readable and writable tag of the material to be processed. The readable and writable tag can be installed or pasted on the material to be processed. The material processing information may include the order number and batch number of the material to be processed, as well as the process parameters and equipment operation parameters at the previous workstation.

[0037] Specifically, the workstation is provided with a tray carrying the material to be processed. The pressure sensor automatically collects the pressure data in the processing process of the manufacturing system, and can detect whether the material to be processed has reached the tray of the workstation. At this time, the controller receives the in-place signal of the tray, controls the lifting cylinder of the workstation to lift up, and the tray rises, so that the distance between the first read-write device and the read-write label is less than the preset distance, so that the first read-write device can be controlled to read and store the material processing information of the read-write label, and store the material processing information in the data exchange area of ​​the controller. In addition, after receiving the in-place signal of the tray, the controller modifies the entry mark of the first data area to the first mark. When the management module obtains the entry mark as the first mark in real time, it determines that the entry and exit request of the workstation is an entry request, and then the management module reads and saves the material processing information of the data exchange area included in the controller. At this time, the management module obtains the material processing information in order to check the processing situation of the previous workstation. When the material to be processed has completed the process operation of the current workstation, the controller modifies the exit mark of the first data area to the second mark. When the management module obtains the outbound mark as the second mark in real time, it determines that the inbound and outbound request of the workstation is an outbound request, and then the management module reads and saves the material processing information of the data exchange area included in the controller. At this time, the management module obtains the material processing information in order to save the processing status of the current workstation.

[0038] It can be understood that when it is determined that the entry and exit request of the workstation is an entry request, if the management module determines that the material to be processed at the current workstation meets the entry requirements based on the material processing information, it is determined that the current workstation can perform the entry operation. When it is determined that the entry and exit request of the workstation is an exit request, if the management module determines that the material to be processed at the current workstation meets the exit requirements based on the material processing information, it is determined that the current workstation can perform the exit operation. Specifically, if the material processing information meets the entry requirements of the current workstation, the management module sends a signal to the controller to allow entry, and the controller controls the entry operation of the current workstation and performs the processing procedure. If the material processing information meets the exit requirements of the current workstation, the management module sends a signal to the controller to allow exit, and the controller controls the exit operation of the current workstation. Specifically, when performing the exit operation, the controller can control the read-write device to write information such as process parameters and equipment operation parameters to the read-write tag, and then control the jacking cylinder to descend, and then control the material blocking cylinder to descend, and release the material to be processed to the next workstation or leave the manufacturing system.

[0039] Through the above technical solution, the manufacturing system includes a controller, a management module and multiple workstations, each workstation is used to execute a processing procedure for the material to be processed, and the control method is applied to the management module. For each workstation, by real-time acquisition of the first data area information in the controller, the first data area includes a preset flag; the entry and exit request of the workstation is determined according to the preset flag; and the corresponding entry or exit operation is performed according to the entry and exit request. The management system collects the data of the controller in the processing process in real time to analyze the entry and exit situation of the material to be processed when executing the processing procedure at each workstation, so as to perform the corresponding entry and exit operations, thereby optimizing the production process and improving the efficiency of batch production.

[0040] In an embodiment of the present application, determining whether a workstation performs a corresponding entry operation or exit operation for an entry / exit request based on the entry / exit request and the material processing information includes: when the entry / exit request is an entry request, determining a first execution result of a previous workstation corresponding to the workstation for the material to be processed based on the material processing information; modifying the entry mark to a first mark based on the first execution result, so that the controller confirms that the workstation performs an entry operation for the entry request through the first mark; when the entry / exit request is an exit request, determining a second execution result of the workstation for the material to be processed based on the material processing information; modifying the exit mark to a second mark based on the second execution result, so that the controller confirms that the workstation performs an exit operation for the exit request based on the second mark.

[0041] It can be understood that, through the workstation's entry request, the first execution result of the previous workstation for the material to be processed needs to meet the entry requirements. Similarly, for the workstation's station request, the second execution result of the current workstation for the material to be processed needs to meet the exit requirements. For example, for the PCR manufacturing system, if the result of the photo detection of the previous workstation is unqualified, the first execution result is unqualified, and the material to be processed cannot enter the current workstation for processing. And if the result of the photo detection of the current workstation is unqualified, the second execution result is unqualified, and the material to be processed cannot enter the next workstation for processing. Then, the management module can modify the entry mark and the exit mark, and modify them to preset marks that can be interpreted by the controller, so that the controller can use the modified exit mark to confirm whether the workstation can perform the corresponding entry operation and exit operation for the exit request.

[0042] In an embodiment of the present application, determining whether the workstation performs the corresponding entry operation or exit operation for the entry and exit request based on the entry and exit request and the material processing information includes: when the first execution result is qualified, modifying the entry mark to a third mark, so that the controller controls the workstation to perform the entry operation for the entry request through the third mark; after completing the entry operation, restoring the entry mark to the first initial mark, and causing the controller to control the workstation to perform the processing procedure for the material to be processed; when the first execution result is unqualified, modifying the entry mark to a fourth mark, so that the controller prohibits the workstation from performing the entry operation through the fourth mark.

[0043] In an embodiment of the present application, the control method also includes: when the entry mark is the fourth mark, modifying the entry return code included in the first data area to the first fault code according to the material processing information, so that the controller parses the first fault code to determine the corresponding first fault cause; restoring the entry mark from the fourth mark to the first initial mark, so that the entry operation is re-executed after the first fault cause is eliminated.

[0044] Specifically, PLC, MES system, EAP (Equipment Automation Platform) equipment automation platform and EQ (Equipment) equipment end communicate through Siemens S7 protocol. Among them, EQ belongs to the field equipment end and exchanges data with EAP of MES system. EAP is a data acquisition system responsible for the communication and acquisition of field equipment data. The entry mark is a Byte word in the first data area of ​​PLC, the default initial value is 0, the entry return code is a Word, and no alarm is 0. When the material pallet arrives at the preparation position of the workstation, it is fed back to PLC through in-situ detection. PLC changes the entry mark in the data area to 1, reads the material processing information in RFID, and saves it to the data exchange area. PLC data area mark 1 indicates that this workstation sends an entry request to MES. After the EAP end of MES system obtains the PLC data area in real time and becomes 1, it is considered that the workstation has an entry request. At the same time, EAP reads the data in the PLC data exchange area and determines the execution completion result of the previous workstation on this workstation. If the MES system determines that the first execution result of the previous process is qualified, the entry mark of the first data area of ​​the PLC is changed to 2; the entry mark 2 of the first data area indicates that the entry judgment is passed and the entry operation can be performed. At this time, the PLC recognizes the first data area label 2, first lifts the material tray and executes the processing steps of this process, and at the same time restores the entry mark of the first data area to the first initial mark 0. If the MES system determines that the first execution result of the previous process is unqualified, the entry mark of the first data area of ​​the PLC is changed to 3. The entry mark 3 of the first data area indicates that the entry judgment is not passed, enters the fault mode, and terminates the entry operation. At this time, the PLC recognizes the first data area label 3, and according to the MES judgment result, the entry return code of the first data area is changed to the first fault code agreed by both parties (see the entry fault error handling code table 1 for details), the equipment prohibits processing and does not allow entry, and the entry mark is restored to 0, so that the entry operation is re-executed after the first fault cause is eliminated.

[0047] In an embodiment of the present application, the outbound mark is modified to the second mark according to the second execution result, so that the controller confirms that the workstation performs the outbound operation for the outbound request according to the second mark, including: when the second execution result is qualified, the outbound mark is modified to the fifth mark, so that the controller controls the workstation to perform the outbound operation for the material to be processed through the fifth mark; after completing the outbound operation, the outbound mark is restored to the second initial mark, and the controller controls the material to be processed to enter the next workstation; when the second execution result is unqualified, the outbound mark is modified to the sixth mark, so that the controller prohibits the workstation from performing the outbound operation for the outbound request through the sixth mark.

[0048] In an embodiment of the present application, the control method includes: when the outbound mark is the sixth mark, modifying the outbound return code included in the first data area to a second fault code according to the material processing information, so that the controller parses the second fault code to determine the corresponding second fault cause; restoring the outbound mark from the sixth mark to the second initial mark, so that the controller controls the manufacturing system to release the material to be processed to the recycling station according to the second fault cause.

[0049] Specifically, PLC, MES system, EAP (Equipment Automation Platform) equipment automation platform and EQ (Equipment) equipment end communicate through Siemens S7 protocol. Among them, EQ belongs to the field equipment end and exchanges data with EAP of MES system. EAP is a data acquisition system, responsible for the communication and acquisition of field equipment data. The outbound flag is another Byte word in the first data area of ​​PLC, and the default initial value is 0; this area is different from the outbound flag. The outbound return code is a Word, and 0 is no alarm. When the material tray completes the process processing, PLC changes the outbound flag of the first data area to 1, and saves the process parameters and equipment operation parameters of this workstation in the data exchange area. PLC sets the outbound flag of the first data area to 1 to indicate that this workstation sends an outbound request to MES. After the EAP database of MES system obtains the outbound flag in real time and it becomes 1, it is considered that the workstation has an outbound request. At the same time, EAP reads the data in the data exchange area of ​​PLC, saves the processing results to the MES database, and judges the execution completion result of this process. If the MES system determines that the second execution result of this process is qualified, the exit mark of the second data area is changed to 2. The exit mark 2 indicates that the exit judgment is passed and the exit operation can be performed. At this time, the PLC recognizes the exit mark 2 of the first data area, first transfers the material pallet to the preparation position of the next workstation, and at the same time restores the exit mark of the first data area label of the PLC to the second initial mark 0. If the MES system determines that the second execution result of this process is unqualified, the exit mark of the first data area of ​​the PLC is changed to 3. The exit mark 3 of the second data area indicates that the exit judgment is not passed, enters the fault mode, and terminates the exit operation. At this time, the PLC recognizes the exit mark 3 of the first data area, and according to the judgment result of the MES, changes the entry return code of the first data area to the second fault code agreed by both parties (see the exit fault error handling code table 2 for details), the equipment is prohibited from processing and exit is not allowed, and the exit mark is restored to 0.

[0052]

[0053] In one embodiment, the normal process of entering the station is as described above, but if the entry request fails, that is, the entry flag is 12, the first fault code of the MES may be any one or more of the above error codes, the processing equipment can prompt an alarm, and the PLC can parse the error code to find the first fault cause of the workstation. After the fault is resolved, you can press the reset button at the processing equipment to reset and re-enter the station. If there is no error, the entry is successful. If there is an error, parse the error, find the first fault cause, press the reset button at the equipment to reset, and re-enter the station until the entry is successful, otherwise repeat the above process.

[0054] In one embodiment, the normal outbound process is as described above, but if the outbound request fails, that is, the outbound flag is 22, the MES outbound return error code may be any one or more of the above error codes, the processing equipment can prompt an alarm, the PLC automatically saves the alarm record, and analyzes the error code to find the second fault cause, reset the equipment, and release the equipment. If the current process is NG, the subsequent workstations will not perform the entry operation and will be released directly until they flow into the recycling station.

[0055] Through the above technical solution, the management module of the manufacturing system obtains the entry mark and exit mark of the first data area included in the controller in real time, modifies the entry mark according to the execution result of the previous workstation, modifies the exit mark according to the execution result of the current workstation, and determines whether to perform the corresponding entry operation or exit operation according to the process parameters and equipment operation parameters transmitted by the read-write tag, completes the entry and exit operations in the manufacturing process, and realizes intelligent production. By connecting the MES system and the PLC, real-time inspection and automated control of the production process of the PCR equipment can be achieved, and centralized process optimization, manufacturability optimization, and engineering layout adjustment can be performed. By collecting processing data and entry and exit data in the processing process in real time and analyzing them to optimize the production process, production efficiency can be improved.
