Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not All the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work, all belong to the protection scope of the present invention.

Example 1

As shown in FIG. 1 , the first embodiment of the present invention provides a multi-process route transfer method based on a PLM system, which splits a process file into a process table and a process table. The process table is the content of all the process routes under the same material and the specific work content of the process. The process table records the material number, document number, process number, process sequence number, parallel process, equipment units and other related resources required for production, and is stored in the PLM system. In the PLM system, through the process route folder composed of the approved process files and system material files, extract the required content of the process table to form a process route table, and the technicians maintain the specific process information in the process route table, and then The process route is issued according to the interface specification requirements with APS and MES. Specifically, the method of this embodiment includes the following steps:

S1. Create a route folder according to the material type, create and edit the craft file under the route folder and save it.

In the step S1, when the material corresponds to multiple process routes, multiple process route folders corresponding to the process routes are created, and a corresponding process file is created and edited under each process route folder. As shown in Figure 2, it is a schematic diagram of the directory of the route folder. Among them, the first-level folder name SW-002-5 corresponds to a product name, and there are two second-level folders. The naming format is: material code\workshop code\routing number_routing name. Among them, the XLS file in the secondary folder is the process file, and the secondary folder also includes a material file (80411435). The PLM system can identify the 4 attributes in the route folder name, generate a route master table ID correspondingly, and generate the corresponding craft table at the same time. When the process route needs to be upgraded, based on the condition that these 4 attributes remain unchanged, the upgrade action is performed to generate a new process table to replace the previous one.

Further, in the step S1, when the process file is created under the process route folder, the process route of the approximate material/product is reused. The specific method is: extracting the information of the approximate process route, and opening a new process table maintenance interface display on the PLM system.

S2, according to the process file under the process route folder, generate a process table under the process route folder; the header information of the process table includes the process route sub-table ID, the process route main table ID, the document number, the document part number, Document version, document name, process number, process description, process sequence number, parallel process number, equipment group number, equipment group description, etc. In addition, each row of the process table corresponds to a process file.

As shown in FIG. 3 , it is a schematic diagram of a specific process table in this embodiment. Its header includes:

Process route sub-table ID: the ID used to store the process file, which is automatically generated according to the sequence of the process;

Routing master table ID: the ID used to store the routing; it is automatically generated based on the four attributes of the material number, factory information, routing number, and routing name in the routing folder name;

Document number: the number used to store the process file; this information is the system number, obtained from the system property attached to the process file (in .xlsm format);

Document name: the document name used to store the craft file;

Process number: used to store process number information; process number information is obtained from the system information corresponding to the document number. Specifically, the process file can be copied from the process file template in the system. When the process file template is configured, it has been equipped with four attributes: document name, document classification, process number, and process name. After copying, a new process file is obtained. , the copy action will be carried out with these four attributes, so the document number of the process document has the information of the corresponding process number in the system.

Process description: used to store the description information of the process file;

Process sequence number: the sequence number used to store the process file;

Parallel process: the parallel sequence number used to store the process file; the process sequence number and the parallel process number are maintained by the process personnel as needed in the process table;

Equipment unit number: used to store the equipment unit number corresponding to the process file;

Equipment unit description: used to store the description information of the equipment unit corresponding to the process file.

Specifically, on a function page in the PLM system, the corresponding relationship information of the process number, process description, equipment group number, and equipment group description can be maintained. When the PLM system generates the process table, the process number is retrieved from the function page. Corresponding equipment group number and equipment group description information.

S3. After maintaining and saving the specific process in the process table, the process route is issued according to the interface specification, and the process route includes all process files and process tables under the process folder.

In the step S3, it also includes the following steps: after maintaining and saving the specific process in the process table, sending the PLM file to the ER for approval, enabling a new process route after the approval, and downloading the process route according to the interface specification. send. Among them, when sending ER for approval, after exporting the process table into an excel file, the excel file is sent to ER for approval.

Specifically, in the step S3, maintaining the specific process in the process table refers to editing and maintaining the process sequence numbers and parallel processes corresponding to each process file in the process table according to the process route.

Further, in this embodiment, the specific process in the process table is maintained, and the process file in the same process table can also be reused, that is to say, two lines in the process table can share a process file. The process route needs to reuse one of the process files, that is, when the process is repeated, you can select the corresponding line in the interface of the process table and click "New entry", then PLM will add a new line to the process table, and then manually modify the process. The purpose of reusing process files can be achieved by maintaining the specific process of the table.

Specifically, in this embodiment, before maintaining the specific process in the process table, the following steps are further included: deleting the "process sequence number" and "parallel process attribute" in the corresponding process file.

S4. After the maintenance of the process route is completed, the information of the process table in each process route is extracted and stored in the process table.

In the process table, each row corresponds to a process route, and the process table information includes: description of each process route, factory, material, version number, creator, effective state, creation date, and effective date.

Specifically, as shown in FIG. 4 , which is a schematic diagram of a specific process table in this embodiment, the header includes:

Routing master table ID: the ID used to store the routing;

Routing description: used to store the description information of the routing;

Factory: used to store the factory information corresponding to the process route;

Material: used to store the material information corresponding to the routing;

Version number: used to store the version number information of the routing;

Created by: the creator information used to store the routing;

Effective status: used to store the version status information corresponding to the routing; the version status includes invalid, under approval, and valid;

Creation date: used to store the creation date corresponding to the routing;

Effective Date: used to store the effective date corresponding to the routing.

The demand scenario solved by the multi-process route delivery method in this embodiment may be: after the process route is issued, due to process optimization or other reasons, the process route needs to be changed/optimized (not newly added). For example, the axle radial flaw detection is completed after three holes are drilled, but due to customer representative requirements (or standard requirements, construction requirements, etc.) radial flaw detection is changed to be completed before three holes are drilled.

That is to say, the requirement scenarios to which the method of this embodiment can be applied include: 1. The specific process files in the folder are not changed, but only the sequence of processes in the process route is changed. 2. The process files and process tables in the process route are changed at the same time.

Further, when adding or modifying a process route, first prepare process file data (including process cards, production tools, MES production parameters, and APS necessary tools). Under the process folder structure, a new route folder is added. The folder is named after the factory and route. When a material has multiple routings, create multiple routing folders respectively, and the PLM system allows multiple routings to be valid at the same time.

At the same time, in order to improve the user experience, the solution needs to be able to adjust both the process sequence of a single material and batch adjustments of multiple materials. The routing change can be controlled (adding approval process for control), the last edited content, time, and personnel of the routing table can be recorded, the system can be automatically saved, and the routing of multiple materials can be queried and exported in batches.

In the step S1, when editing the process file, it also includes the step of deleting two attributes of "equipment number" and "equipment description" from the document classification attributes.

In this embodiment, when there are multiple routings for a certain material under the finished product, there is no need to create multiple routings for other materials. For example, in the production and processing of finished wheel products, there will be multiple materials (or intermediate products) such as rough wheels, rough hole wheels, and fine hole wheels. Among them, only the wool wheel has the problem of multiple process routes, because there are multiple factories and production lines that can produce the hair wheel. Therefore, you only need to create multiple routing folders for the gross wheel without modifying the routings of other materials. After the establishment and saving of the multi-routing folder, the routing description, plant, material number, and version number can be transferred to MES and APS.

Specifically, in this embodiment, each material/product has its own process route file. If there is an approximate product process route that can be reused, the approximate process route information is extracted, and a new process table maintenance interface is displayed on the PLM.

Technologists maintain fields in the maintenance interface of the process table: process sequence number, parallel process number, store the information in the process table, export the EXCEL file (read-only state) after confirmation, and the EXCEL file export is automatically named: process route number (unique). Code, i.e. process route master table ID)-version, EXCEL file content and process table content information completely chair. Then submit the exported EXCEL file to go through the ER approval process. After the approval, the PLM background compares the process route number of the EXCEL file to directly activate the new process route (premise: only one effective file can exist in a process file directory).

When numbering the process in the process table, or dealing with the problem of parallel processes, you can delete the attributes of "process sequence number" and "parallel process" from the attributes of the process file. In addition, develop the system interface in the SAP ERP system, In this interface, the process file corresponding to the material is inquired, and the process sequence number and parallel process are manually maintained in this interface and saved to the system.

Specifically, in this embodiment, the material process route finally transmitted to the APS through the PLM system needs to be clearly divided into process versions (corresponding to different production lines in different factories), and the process route needs to have process sequence numbers.

In the process table, the automatically generated and read-only columns are: process route main table ID, process route sub-table ID, document number, document part number, document version number, document name, process number, process description, equipment unit number, Equipment group description. The columns that users need to maintain manually are: process sequence number, parallel process.

In the multi-routing, each routing is controlled by the version, and the version status is invalid, in approval, and effective. You can call the retrieval module to query the historical version through routing retrieval. In addition, you can also call the retrieval module to query the routing information by factory, work center, material number, and version, and the query result is given in the form of a process table. Among them, the version status of the routing is identified by the system brake. When the system has not completed the approval process, the routing is in the status of approval. After the system recognizes the approved process, it updates the routing to the effective version. The current routing is saved in a new version, the past version is automatically invalid, and the status is irreversible.

In this embodiment, the process route can be changed, and the process sequence of a single material can be adjusted. The routing change is controlled by the document approval process (approval of the exported routing EXCEL), which can record the last edited content, time, and personnel of the routing table, and automatically save the system. You can query and export the routings of multiple materials in batches.

When managing the equipment used in the multi-process route, delete the two attributes of "equipment number" and "equipment description" from the classification attributes of the process file, so that this group of data can be managed in the MES, and the equipment group number needs to be manually maintained and the corresponding information of the device number. "Equipment unit number" and "equipment unit description" are maintained in the corresponding table of equipment unit information and process information in the system, managed by the PLM system, and automatically correspond to and write the corresponding equipment unit information through the process information when acquiring the process table, and transmit data of this type. When the APS system arranges the process plan, according to the unit information in the process information, the system defaults to schedule production to a device corresponding to the unit. If you need to specify the equipment, you need to specify the corresponding equipment in the process or the planner manually arranges it. The device is manually selected in the production system.

In addition, the method of the present invention is also applicable to the scenario where the same material, the same place, the same unit, 2 sets of equipment, and 2 sets of different process files are used to construct the process route, for example, 2 sets of wheel set presses, with different equipment and the same function, currently In the same unit but with different process documents, the application can define different units through the PLM system and build different process routes.

Further, in this embodiment, the process table maintenance module is further configured to add new entries in the process table, so as to reuse process files in the same process folder. As shown in Figure 7, in the interface of the process table maintenance module, select the row corresponding to the process file to be reused, and then click the new entry, the process table maintenance module will add a new row in the process table interface, which is the same as the original one. The selected row reuses the same process file, and then only needs to edit and maintain the process sequence number and parallel process corresponding to each row in the process table according to the process route, and then the update of the process table and process route can be completed. Through the above operations, the multiplexing efficiency of the process files can be further improved.

To sum up, the present invention provides a multi-process route transfer method based on the PLM system, by setting the process table and the process table on the basis of the process file, using the process table to record the specific relevant information of the process route and modify the process sequence and parallel processes, so that each process route can reuse process files, and use the process table to record the specific conditions of each process route, which can facilitate the reuse and query of each material and factory process route, reduce the labor cost of process maintenance, and improve Improve the efficiency of route maintenance.
