Description

Background Art

[0002] Surface Mount Technology (SMT) is a core manufacturing process in the Printed Circuit Board Assembly (PCBA) industry. In the actual production process, different quantities and different types of patch production orders will be received, and the materials required for each patch are different. Therefore, when changing the SMT production line, it is necessary to frequently change the materials on the placement machine according to the material station table of each patch. Each change involves the process of loading and unloading the materials of the previous patch from the placement machine station, and then installing the new materials on the station according to the material station table of the new patch, which results in a long line change time for SMT patches, affecting production efficiency.

[0003] Therefore, improving the production efficiency of SMT patches has become an urgent problem to be solved in the PCBA industry. Summary of the invention

[0004] The embodiments of the present application provide a material station table merging method, a production method and an apparatus for multi-format patch products, which are used to improve the production efficiency of SMT patches.

[0005] In a first aspect, an embodiment of the present application provides a method for merging material station tables of multiple patch products, including:

[0006] In response to the patch product query operation, the initial material station table of the patch product set to be produced is obtained and displayed in the main table area of ​​the interface; wherein, the patch patterns of different patch products in the patch product set to be produced are different, and each initial material station table contains the materials required for the patch products of the corresponding pattern and the storage position of the materials on the feeder, and the initial material station table is generated based on the material list corresponding to the patch work order and the station arrangement sequence information corresponding to the patch machine set, and the station arrangement sequence information is determined according to the moving path of the patch head to absorb the material;

[0007] In response to the merging operation of multiple initial material station tables, one is selected from the multiple initial material station tables as a basic material station table, and the basic material station table is compared with the first material station table; wherein the first material station table is any initial material station table among the multiple initial material station tables except the basic material station table, and the number of merged initial material station tables is determined based on the number of stations included in the set of placement machines;

[0008] If the values ​​of the storage position column of the basic material station table and the first material station table are the same but the values ​​of the material column are different, the value of the material column in the first material station table is added to the material column of the basic material station table to obtain the target material station table.

[0009] The beneficial effects of the above technical solution are: for patch orders with small quantities and various versions, an initial material station table for each type of patch product is generated based on the material list corresponding to the patch work order and the station arrangement order information corresponding to the patch machine set. Each initial material station table contains the materials required for the corresponding type of patch product and the storage position of the materials on the feeder. If the initial material station table is used directly for patch production, it will involve the production transfer process of the previous version of the patch product material going offline and the next version of the patch product material going online. Therefore, the query operation of the patch product set to be produced is performed based on the visual interface, and the initial material station tables of the patch product sets to be produced of different versions are displayed in the main table area of ​​the interface, and selection is made from them. Select multiple initial material station tables and merge them one by one, merge the materials with the same value in the storage position column but different value in the material column in each two material station tables into one material station table, so as to ensure that the patch head can accurately absorb the material during the production of patch products, and because the merged target material station table contains the materials required for patch products of various types, and the number of the merged initial material station tables is determined according to the number of stations contained in the patch machine set, the number of stations of the patch machines on the production line can meet the needs of simultaneous production of patch products of multiple types. In this way, the patch machine set can continuously produce patch products of various types at one time based on the materials on the target material station table, effectively reducing the number of production changes and improving production efficiency. On the other hand, the station position of the patch machine set is determined according to the moving path of the patch head to absorb the material, and the efficiency of patch production can be further improved by minimizing the moving path.

[0010] Optionally, in response to the merging operation of multiple initial material station tables, selecting one from the multiple initial material station tables as a basic material station table includes:

[0011] In response to a selection operation of a plurality of initial material station tables in the main table area, displaying the selected plurality of initial material station tables in a merge area of ​​the interface;

[0012] In response to a merging operation on a plurality of initial material station tables within the merging area, one is selected from the plurality of initial material station tables as a basic material station table.

[0013] The beneficial effects of the above technical solution are: selecting and merging material station tables based on a visual interface, realizing a one-key production change function for material station tables required for different types of patches, and the operation is simple and convenient.

[0014] Optionally, the method further includes:

[0015] In response to the selection operation of the material station table, the details of the material station table are displayed in the sub-table area of ​​the interface; wherein the material station table includes the initial material station table or the target material station table.

[0021] The material locations in the material list and the material locations in the pre-imported station arrangement sequence information are checked to generate an initial material station table.

[0022] The beneficial effect of the above technical solution is: since the imported station arrangement sequence information is a computer-readable file, which is not convenient for people to read, an accurate and human-readable initial material station table is obtained by checking with the material points in the bill of materials. In this way, the initial material station table of each type of patch product generated by the patch work order based on multiple types of patch products is subsequently merged, so that the merged target material station table contains all the materials required for multiple types of patch products.

[0023] Optionally, after obtaining the target material station table, the method further includes:

[0086] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the technical solution of the present application, rather than all of the embodiments. Based on the embodiments recorded in the application documents, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the technical solution of the present application.

[0087] Based on the exemplary embodiments shown in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In addition, although the disclosure in this application is introduced according to one or several exemplary examples, it should be understood that each aspect of these disclosures can also constitute a complete technical solution separately.

[0088] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0089] The terms "first", "second", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise indicated. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, for example, they can be implemented in an order other than those given in the diagrams or descriptions of the embodiments of this application.

[0090] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0091] The term "module" as used in this application refers to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and / or software code that is capable of performing the functions associated with that element.

[0092] The terms in the embodiments of the present application are explained below.

[0093] Systems, Applications, and Products (SAP): provides an enterprise management software that includes multiple modules such as financial accounting, material management, procurement, sales, and production planning.

[0094] Advanced Planning and Scheduling (APS): is an advanced planning and scheduling software system based on supply chain management and constraint theory. It generates detailed plans by simultaneously considering the constraints of multiple limited capacity resources, according to various preset rules, and through very complex intelligent mathematical algorithms, it repeatedly simulates, tests, optimizes, and calculates.

[0095] Manufacturing Execution System (MES): A system that focuses on production process management.

[0096] The following is an overview of the design concept of the embodiments of the present application in conjunction with application scenarios.

[0097] In the traditional SMT patch production process, many small orders are generated. The number of patches required for these small orders is small but the types are wide, and frequent production changes are often required, which not only affects production efficiency but also increases production costs.

[0098] In view of this, the embodiment of the present application provides a method for merging material station tables for patch products of various types. The method merges material station tables based on a visual interface. For work orders for patch products of various types, a query operation of the patch product set is performed in the interface, and the initial material station tables of patch products of different types are obtained and displayed, and then the displayed multiple initial material station tables are merged. During the merging process, one is selected from multiple initial material station tables as a basic material station table, and the basic material station table is compared with the other initial material station tables one by one. When the values ​​of the storage position column in the two tables are the same but the values ​​of the material column are different, the values ​​of the material column in the other initial material station tables are added to the material column of the basic material station table, so that the multiple initial material station tables are merged into a target material station table. When the materials required for various types of patch products are merged, the storage position of the materials on the feeder is kept the same. In this way, it can be ensured that the patch head accurately absorbs the required materials from the corresponding position to ensure normal production after the merger. In addition, since the merged target material station table contains all the materials required for various types of patch products, when the materials are put online according to the target material station table, continuous generation of various types of patch products can be achieved without switching production, thereby improving the production efficiency of SMT patches.

[0099] On the other hand, an embodiment of the present application provides a method for producing multi-type patch products. For patch products of different types, each time the barcode is scanned, a target material station table based on the merger of initial material station tables of patch products of multiple types will be obtained, and online materials will be checked according to the target material station table. Since the target material station table contains all the materials required for patch products of multiple types, continuous production of patch products of different types will be automatically carried out after verification, without the need for production change, thereby improving the production efficiency of SMT patches.

[0100] See also Figure 1, a system architecture diagram of a material station table merging method is provided to realize the embodiment of the present application, and the system architecture includes four parts: an information management and control system, an API gateway, a fusion integration platform, and a database. The information management and control system is based on the current mainstream MES in the PCBA industry, and realizes the merging function of the material station table through software development technology. The information management and control system is mainly used to provide a UI interface for operations such as selection, merging, and station maintenance of the material station table, automatically compare materials for the selected material station table, merge the material station table according to the comparison results, store the material station table in the database, and connect the service interface of the fusion integration platform through the API gateway to obtain data. Among them, the acquired data includes but is not limited to the patch work order issued by the APS system and the bill of materials (BOM) in the SAP software. The API gateway is mainly used for communication between different systems. It is an important tool for standardizing the application programming interface (API) between business systems and realizing standardized integration between business systems. As a centralized management and control platform for API services, the fusion integration platform is used for publishing and subscribing to service interfaces, supporting each business system to publish services externally and call third-party services. The database is used for the storage and management of material station tables and BOMs, including but not limited to Oracle, MySQL, SQL Server, DB2 and other databases.

[0101] Optionally, the system architecture in the present application may also include printing software, such as CodeSoft, etc. Therefore, the information management and control system may also call the printing software to drive the printer to print the material station list for verification on the production line.

[0102] It should be noted that the embodiment of the present application does not impose any restrictive requirements on the software technology of the material station table merging function. For example, it can be developed on the .NET platform using the C# language.

[0103] Take the current mainstream CM602 placement machine with 4 multi-function placement heads as an example. Figure 2 As shown, it contains 108 stations and can install multiple feeders at the same time. These feeders are fixed on the feeding cart (i.e., table cart) to supply materials to the placement machine in an orderly manner.

[0104] In order to realize mixed order production of SMT patches of different board types, the number of SMT machines on the SMT production line can be configured according to the patch work order. The more SMT machines there are, the more distributed stations there are, and the more types of SMT patches can be mounted at the same time.

[0105] When the positions of the placement machines on the SMT production line meet the needs of simultaneous production of multiple types of patches, production can be carried out based on the existing production line scale. When the positions of the placement machines on the SMT production line cannot meet the needs of simultaneous production of multiple types of patches, the number of placement machines can be increased to add more positions.

[0106] Still taking CM602 placement machine as an example, Figure 3 As shown in the figure, for the mixed order production line of SMT patches, the original two CM602 patch machines are increased to three CM602 patch machines, and 108 stations are added accordingly, which can meet the simultaneous binding of 5 types of patch product materials at one time. Among them, each CM602 patch machine contains 4 multi-functional patch heads, which can simultaneously absorb 4 materials from the feeders corresponding to different stations and provide them to the PCB board each time. Among them, the function of the TRAY box is similar to the station. Due to the different shapes and sizes of the materials, the storage positions on the feeders are different, and the corresponding stations are also different.

[0107] It should be noted that Figure 2 and Figure 3 This is only an example of a placement machine. The embodiment of the present application does not impose any restrictive requirements on the model of the placement machine, the type of feeder, the number of added placement machines, etc. On the actual SMT production line, a flexible choice can be made based on factors such as equipment cost and site.

[0108] For patch work orders of different types, based on the set of patch machines composed of multiple patch machines on the SMT patch production line, determine the movement path of the patch head to absorb the materials required for patch products of different types, and pre-generate the station arrangement sequence information according to the movement path and import it into the MES system.

[0109] In one example, to ensure patch efficiency, the station arrangement sequence information can be determined based on the principle of the shortest moving path. Specifically, according to the frequency of use of materials and the storage position on the feeder when patching products of different versions, the stations included in the patch machine set are arranged and reorganized so that the moving path of the patch head on the station when absorbing the material is the shortest, and the final station arrangement sequence information is obtained and imported into the MES system.

[0110] The station table is the basic data for SMT patches. Therefore, for patch work orders of different types, the corresponding initial material station table needs to be generated in advance.

[0111] like Figure 4The figure shows the process of generating the initial material station table. After entering patch work orders of different types into the APS system, the APS system will schedule the production process for the entered patch work orders, generate a shift production plan, and send the shift production plan to the MES system through the interface address of the API gateway on the fusion integration platform. The MES system calls the SAP system through the fusion integration platform based on the product material number of each type of patch product in the shift production plan, obtains the BOM address corresponding to the corresponding product material number, and obtains the bill of materials of the corresponding type of patch product based on the BOM address and stores it locally, and generates the initial material station table of the corresponding type of patch product in combination with the imported station sorting order information.

[0112] Specifically, the generation process of the initial material station table is as follows: Figure 5A As shown, it mainly includes the following steps:

[0113] S501: Obtain a shift production plan generated based on patch work orders for patch products of various formats.

[0114] The MES system obtains the pre-generated shift production plan from the APS system through the integrated fusion platform. The shift production plan includes the production sequence of various patch products. Therefore, the unique product number corresponding to each patch product can be selected in the MES system in order according to the production sequence, thereby generating the initial material station table in order.

[0115] like Figure 5B As shown in the figure, it is the interface for the APS system on the fusion integration platform to send shift production plans to the MES system.

[0116] S502: In response to the generation operation of the current product material number, obtain and cache the bill of materials corresponding to the current product material number.

[0117] The MES system responds to the generation operation of the current product material number, calls the SAP system through the fusion integration platform, obtains the bill of materials corresponding to the current product material number, and saves it locally in the MES system.

[0118] S503: Check the material locations in the bill of materials and the material locations in the pre-imported station arrangement sequence information to generate an initial material station table.

[0119] The MES system ensures the accuracy of the generated initial material station table by checking the material points and material stations.

[0120] After generating the initial material station tables for various types of patch products, the multiple initial material station tables are stored in the database for subsequent use.

[0121] The initial material station table for each type of patch product contains the materials required for the corresponding type of patch products and the storage positions of the materials on the feeder. Therefore, patches of various types can be produced based on multiple initial material station tables. Taking into account that the materials used for patch products of different types are different, if patch products of corresponding types are generated according to multiple initial material station tables, the production transfer process of the material of the previous type of patch product going offline and the material of the next type of patch product going online will be involved, which is relatively inefficient. Therefore, an embodiment of the present application provides a material station table merging method for patch products of multiple types, which is applied before patch production, by merging multiple initial material station tables into one material station table, thereby obtaining all the materials required for patch products of various types, reducing the number of production transfers, and improving the production efficiency of SMT patches.

[0122] See also Figure 6 , which is a material station table merging method process for multi-format patches provided in an embodiment of the present application, mainly includes the following steps:

[0123] S601: In response to the patch product query operation, an initial material station table of the patch product set to be produced is obtained and displayed in the main table area of ​​the interface.

[0124] On the visual interface of the MES system, users can query all or part of the patch products to be produced on the current SMT production line in the toolbar. Different patch products have different patch patterns.

[0125] like Figure 7 As shown, when the user searches based on the patch production date, the initial material station table of the patch product set to be produced in different versions during this period is displayed in the main table area of ​​the interface.

[0126] It should be noted that Figure 7 This is just an example. Users can also query the patch products to be produced by entering product information such as product number and product name.

[0127] S602: In response to the merging operation of multiple initial material station tables, one is selected from the multiple initial material station tables as a basic material station table.

[0128] The number of merged initial material station tables is determined based on the number of stations included in the placement machine set. Specifically, the number of merged initial material station tables does not exceed the number of versions corresponding to the number of stations included in the placement machine set.

[0129] Taking a set of three CM602 SMT machines as an example, the number of stations it contains can produce five types of SMT products at the same time. At this time, the initial material station tables of the five types of SMT products can be merged, that is, the number of merged initial material station tables is 5.

[0130] In a specific implementation, in response to the selection operation of multiple initial material station tables in the main table area, the selected multiple initial material station tables are cached and displayed in the merge area of ​​the interface, wherein the number of selected initial material station tables does not exceed the number of versions corresponding to the number of stations included in the placement machine set, and further, in response to the merging operation of multiple initial material station tables in the merge area, one is selected from the multiple initial material station tables as the basic material station table.

[0131] by Figure 7 For example, the user checks the first five initial material station tables in the main table area of ​​the interface. The five checked initial material station tables will be displayed in the merge area of ​​the interface. When the user clicks the "Merge" option in the interface, the MES system automatically merges the five checked initial material station tables. During the merging process, the first initial material station table will be used as the basic material station table.

[0132] It should be noted that the embodiment of the present application does not impose any restrictive requirements on the selection of the basic material station table. For example, the last initial material station table can also be used as the basic material station table.

[0133] In one example, for the displayed initial material station table, the MES system can also respond to the selection operation of the initial material station table, display the details of the selected initial material station table in the sub-table area of ​​the interface, and display the material station table clearly through a visual interface, so that operators can view the material details of various types of patch products.

[0134] For example, Figure 7 As shown, in the sub-table area of ​​the interface, the details of the first initial material station table are displayed.

[0135] S603: Compare the basic material station table with the first material station table to determine whether the values ​​of the storage position column and the material column of the basic material station table and the first material station table are the same. If the values ​​of the storage position column are the same but the values ​​of the material column are different, execute S604; otherwise, end this merging and enter the next round of comparison.

[0136] The storage location is listed as Figure 7 In the process of merging the materials in the basic material station table and the first material station table, by ensuring that the merged materials in the first material station table (that is, the materials that are different from the basic material station table) are stored in the same position on the feeder, it is ensured that the patch head can correctly absorb the materials required for the patch products of the corresponding pattern in the first material station table.

[0137] In the embodiment of the present application, the first material station table is any initial material station table among the multiple initial material station tables except the basic material station table.

[0138] S604: Add the values ​​of the material column in the first material station table to the material column in the basic material station table to obtain the target material station table.

[0139] After each merger, the types of materials at the same storage location in the target material station table are more abundant, and different types of materials correspond to different stations.

[0140] For example, the storage position numbered 1 in the basic material station table before the merger can store 5 types of materials, and the storage position numbered 1 in the target material station table after the merger can store 20 types of materials.

[0141] S605: Determine whether all comparisons are completed. If not, return to S603. If yes, end.

[0142] After comparing the basic material station table with the remaining initial material station tables one by one, the selected multiple initial material station tables can be merged into a target material station table, and the target material station table can be stored in the database with a new name (such as raw material table-HB) for use in material error prevention comparison during production. At the same time, the merged initial material station table in the database is marked as invalid.

[0143] The data structure of the target material station table in the database is shown in Table 1, which includes multiple field names and comments for each field name.

[0146] In the embodiment of the present application, by arranging the positions of the placement machines configured on the SMT production line, the material station table merging function of the MES system is developed using the C# language on the .NET platform. In this way, before production, the staff selects the material station table of different types of patch products in the MES system and clicks the merge option. The MES system then generates a new material station table through the background merging logic while ensuring accuracy, thereby realizing the one-click production change function of the material station table required for different types of patch products.

[0147] like Figure 8 As shown, it is a schematic diagram of the material station table merging effect provided in an embodiment of the present application. The user can query the merged target material station table through the toolbar in the MES system interface.

[0148] In one example, for the queried target material station table, the user can select it in the main table area. In response to the selection operation of the target material station table, the MES system displays the details of the target material station table in the sub-table area of ​​the interface. The display effect is as follows Figure 8 shown.

[0149] In an embodiment of the present application, for patch orders with small quantities and various versions, an initial material station table for each type of patch product is generated based on the material list corresponding to the patch work order and the station arrangement order information corresponding to the patch machine set. Each initial material station table contains the materials required for the corresponding type of patch product and the storage position of the materials on the feeder. If the initial material station table is used directly for patch production, it will involve the production transfer process of the material of the previous type of patch product going offline and the material of the next type of patch product going online. Therefore, a query operation of the patch set to be produced is performed based on a visual interface, and the initial material station table of the patch product set to be produced of different patch versions is displayed in the main table area of ​​the interface, and from it Select multiple initial material station tables and merge them one by one, merge the materials with the same value in the storage position column but different value in the material column in each two material station tables into one material station table, so as to ensure that the patch head can accurately absorb the material during patch production, and because the merged target material station table contains the materials required for patch products of various types, and the number of merged initial material station tables is determined according to the number of stations contained in the patch machine set, the number of stations of the patch machines on the production line can meet the needs of simultaneous production of patch products of multiple types. In this way, the patch machine set can produce multiple types of patches at one time based on the materials on the target material station table, effectively reducing the number of production changes and improving production efficiency. On the other hand, the station position of the patch machine set is determined according to the moving path of the patch head to absorb the material. By minimizing the moving path, the efficiency of patch production can be further improved.

[0150] In one example, the MES system can also be connected to a printer, such as Fig. 9 The following figure shows the printing interface of the material station details. In this way, after obtaining the target material station table, the target material station table can be compared with the material list of the patch to be produced to obtain the key information of the material that has been annotated, and the material station details can be generated based on the key information of the material, and sent to the printer for printing. By printing the material station details, the staff can check according to the printed data on the SMT production line to prevent patch errors.

[0151] Optionally, key material information includes but is not limited to whether the material needs to be programmed, mounting position, etc.

[0152] In the embodiment of the present application, since the merged target material station table contains materials required for patch products of different types, patches of various types can be produced at one time based on the merged target material station table.

[0153] See also Fig.10, is a production method flow of a multi-format patch product provided in an embodiment of the present application, which is applied to a patch machine. It is assumed that the target material station table is the result of merging the initial material station tables of the first product and the second product, and includes the materials required for patching the first product and the second product, wherein the patch patterns of the first product and the second product are different. Specifically, the process mainly includes the following steps:

[0154] S1001: Scan the first barcode of the first product, and obtain the target material station table according to the first barcode.

[0155] S1002: According to the target material station table, check whether all the materials required for the first product are online. If so, execute S1003, otherwise end.

[0156] S1003: Control the patch head to absorb the material corresponding to the first product for patching.

[0157] When the first product is mounted, the mounting process of the second product can be continued without interrupting the SMT production line.

[0158] S1004: Scan the second barcode of the second product, and obtain the target material station table according to the second barcode.

[0159] S1005: According to the target material station table, check whether all the materials required for the second product are online. If so, execute S1006, otherwise end.

[0160] S1006: Control the patch head to absorb the material corresponding to the second product for patching.

[0161] In an embodiment of the present application, on the SMT production line, the materials required for each product are compared one by one according to the merged target material station table. After ensuring that all materials are on the line, products with different patch patterns are generated continuously at one time. The entire process does not require production change, thereby achieving efficient utilization of materials and a continuous and stable production process, effectively improving the efficiency of SMT patches.

[0162] See also Fig.11, which is a complete business process of material station table merging and patch production provided in the embodiment of the present application. In the material station table merging business part, the MES system obtains the shift production plan from the ASP system through the fusion integration platform, and obtains the corresponding bill of materials from the SAP system through the fusion integration platform according to the product material number in the shift production plan, and combines the imported station arrangement sequence information to generate the initial material station table of multiple version patch products and store it in the database. For the set of patch patterns to be produced on the SMT production line, in response to the selection operation of the initial material station table of multiple version patch products, the selected multiple initial material station tables are merged with one click, and the merged target material station table is stored in the database. The MES system prints the material station details containing the key information of the material by calling the printer. In the patch production business part, the patch machine obtains the target material station table from the database for different version patch products to perform material online detection, to ensure that the materials of different version patch products are all and accurately online, and to achieve one-time continuous production of different version patch products.

[0163] The embodiment of the present application merges the initial material station tables of patch products of various types to achieve one-time production of patch products of various types on one SMT production line, thereby reducing the number of production changes and improving production efficiency.

[0164] In actual SMT operations, when producing multi-type patch products based on the merged target material station table, the number of Class A production changes can be reduced, saving more than 4 hours of production change time per shift. The effect is more significant and the reliability is stronger.
