For surface mount orders with small quantities and numerous pattern types, in response to a surface mount product query operation, an initial material station list for different pattern types of surface mount products to be produced is obtained. To reduce the changeover process for different pattern types of surface mount products, in response to a merging operation of multiple initial material station lists, materials with the same location column value but different material column values ​​in two material station lists are merged into one material station list. This ensures that the merged material station list guarantees that the placement head accurately picks up materials for multiple pattern types of surface mount products.

Furthermore, the placement machine's station position is determined based on the movement path of the placement head picking up materials; minimizing the movement path further improves surface mount production efficiency.

Description

Technical Field

[0001] This application relates to the field of material management technology in the electronics manufacturing industry, and provides a method, production method and equipment for merging material station lists for multi-pattern surface mount products. Background Technology

[0002] Surface Mount Technology (SMT) is a core manufacturing process in the Printed Circuit Board Assembly (PCBA) industry. In actual production, orders for surface mount technology (SMT) components of varying quantities and types are received, and each type requires different materials. Therefore, SMT production line changes require frequent changes to the materials at the pick-and-place machine stations according to the material station schedule for each type of SMT component. Each changeover involves removing the materials for the previous type of SMT component from the pick-and-place machine station and then installing the new materials according to the new component's material station schedule. This results in long SMT changeover times and impacts production efficiency.

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

[0004] This application provides a method, production method, and equipment for merging material station lists for multi-pattern surface mount products, which can improve the production efficiency of SMT surface mount technology.

[0005] In a first aspect, embodiments of this application provide a method for merging material station lists for multiple types of patch products, including:

[0006] In response to a product query operation, the initial material station table of the product set to be produced is obtained and displayed in the main table area of ​​the interface; wherein, the different surface mount types of the surface mount products in the product set to be produced are different, and each initial material station table contains the materials required for the corresponding surface mount product type and the storage position of the materials on the feeder. The initial material station table is generated based on the bill of materials corresponding to the surface mount work order and the station layout sequence information corresponding to the surface mount machine set. The station layout sequence information is determined according to the movement path of the surface mount head picking up the materials.

[0007] In response to the merging operation of multiple initial material station tables, one of the multiple initial material station tables is selected as the base material station table, and the base material station table is compared with the first material station table; wherein, the first material station table is any initial material station table other than the base material station table among the multiple initial material station tables, and the number of initial material station tables to be merged is determined based on the number of stations included in the pick and place machine set;

[0008] If the storage location column of the basic material station table and the first material station table have the same value but the material column has a different value, then 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 as follows: For small-volume SMT orders with numerous layouts, an initial material station table for each layout of SMT product is generated based on the bill of materials corresponding to the SMT work order and the station layout sequence information corresponding to the SMT machine set. Each initial material station table contains the materials required for the corresponding layout of SMT product and the storage location of the materials on the feeder. If the initial material station table is used directly for SMT production, it will involve the production transition process of unloading materials for the previous layout of SMT product and loading materials for the next layout of SMT product. Therefore, the query operation of the SMT product set to be produced is based on a visual interface. The initial material station tables of different layouts of SMT product sets to be produced are displayed in the main table area of ​​the interface, and the selection can be made from them. Multiple initial material station lists are selected and merged one by one. Materials with the same location column value but different material column values ​​from two different material station lists are merged into one material station list. This ensures that the placement head can accurately pick up materials during the production of surface mount products. Furthermore, since the merged target material station list contains materials required for various types of surface mount products, and the number of initial material station lists is determined based on the number of stations in the placement machine set, the number of stations on the production line can meet the needs of simultaneous production of multiple types of surface mount products. In this way, the placement machine set can continuously produce multiple types of surface mount products at once based on the materials on the target material station list, effectively reducing the number of turnarounds and improving production efficiency. On the other hand, the station positions of the placement machine set are determined based on the movement path of the placement head picking up materials. By minimizing the movement path, the efficiency of surface mount production can be further improved.

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

[0011] In response to the selection operation of multiple initial material station tables within the main table area, the selected multiple initial material station tables are displayed in the merged area of ​​the interface;

[0012] In response to the merging operation of multiple initial station tables within the merged area, one of the multiple initial station tables is selected as the base station table.

[0013] The beneficial effects of the above technical solution are: the selection and merging of material station lists based on a visual interface enables one-click production changeover of material station lists required for different types of patch panels, making the operation 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.

[0016] The beneficial effects of the above technical solution are: the visual interface clearly displays the material station table, making it easy for operators to view the material details of the patch and correct errors in a timely manner.

[0017] Optionally, the process of generating the initial material station list includes:

[0018] Obtain shift production plans generated from placement work orders based on various types of surface mount products;

[0019] In response to the generation operation of product part numbers selected sequentially based on the shift production plan, the following operations are performed for each selection:

[0020] Retrieve and cache the bill of materials corresponding to the current product part number; each product part number corresponds to a type of patch product;

[0021] The locations of materials in the bill of materials are checked against the locations of materials in the pre-imported station layout information to generate an initial material station table.

[0022] The beneficial effects of the above technical solution are as follows: Since the imported station layout information is a computer-readable file, it is not convenient for human reading. By checking with the locations of materials in the bill of materials, an accurate and easy-to-read initial station list can be obtained. In this way, after merging the initial station lists of each type of SMT product generated from the SMT work orders based on multiple SMT products, the merged target station list contains all the materials required for multiple SMT products.

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

[0024] The target material station list is compared with the bill of materials corresponding to various types of patch products to obtain the key material information that has been noted.

[0025] Based on the key information, a material station list is generated and sent to the printer for printing.

[0026] The beneficial effects of the above technical solution are: by printing the key information of the materials, operators can check the material information on the production line on site, thereby ensuring the continuous and stable production of multi-type patch products.

[0027] Secondly, embodiments of this application provide a method for producing multi-pattern patch products, including:

[0028] According to the target material station list, check whether all the materials required for the first product are online. If so, control the placement head to pick up the material corresponding to the first product for placement.

[0029] Scan the second barcode of the second product and obtain the target material station table based on the second barcode;

[0030] According to the target material station list, check whether all the materials required for the second product are online. If so, control the placement head to pick up the material corresponding to the second product for placement.

[0031] Wherein, the first product and the second product have different patterns, and the target material station table is generated according to any one of the methods in the first aspect.

[0032] The beneficial effects of the above technical solution are as follows: Since the target material station list contains all the materials required for multi-type surface mount products, materials can be put into the SMT production line according to the target material station list, thereby enabling continuous and stable production of surface mount products of different types without the need for production change, thus improving surface mount efficiency.

[0033] Thirdly, embodiments of this application provide a device for merging material station lists for multi-pattern patch products, including:

The initial material station table is generated based on the bill of materials corresponding to the surface mount work order and the station layout sequence information corresponding to the surface mount machine set. The station layout sequence information is determined according to the movement path of the surface mount head picking up the materials.

[0035] The display module is used to display the acquired initial material station table in the main table area of ​​the interface;

[0036] The merging module is used to respond to the merging operation of multiple initial material station tables. It selects one of the multiple initial material station tables as a base material station table and compares the materials of the base material station table with a first material station table. If the storage location column values ​​of the base material station table and the first material station table are the same but the material column values ​​are different, the material column values ​​of the first material station table are added to the material column of the base material station table to obtain the target material station table. The first material station table is any one of the multiple initial material station tables except the base material station table, and the number of initial material station tables to be merged is determined based on the number of stations included in the pick-and-place machine set.

[0037] Optionally, the merging module is specifically used for:

[0038] In response to the selection operation of multiple initial material station tables within the main table area, the selected multiple initial material station tables are displayed in the merged area of ​​the interface;

[0049] Based on the key material information, a material station list is generated and sent to the printer for printing.

[0050] Fourthly, embodiments of this application provide a production apparatus for multi-pattern patch products, comprising:

[0051] The scanning module is used to scan the first barcode of the first product and obtain the target material station table based on the first barcode; and to scan the second barcode of the second product and obtain the target material station table based on the second barcode.

[0052] The detection module is used to detect whether all the materials required for the first product are online, based on the target material station list; and to detect whether all the materials required for the second product are online, based on the target material station list.

[0053] The chip mounting module is used to control the chip mounting head to pick up the material corresponding to the first product for chip mounting when all materials are online; and to control the chip mounting head to pick up the material corresponding to the second product for chip mounting.

[0054] Wherein, the first product and the second product have different patterns, and the target material station table is generated according to any one of the methods in the first aspect.

[0057] In response to a product query operation, the system retrieves the initial material station table for the set of products to be produced and displays the initial material station table in the main table area of ​​the interface. The different surface mount types of the surface mount products in the set to be produced are different. Each initial material station table contains the materials required for the corresponding surface mount type and the storage location of the materials on the feeder. The initial material station table is generated based on the bill of materials corresponding to the surface mount work order and the station layout sequence information corresponding to the surface mount machine set. The station layout sequence information is determined according to the movement path of the surface mount head picking up the materials.

[0058] In response to the merging operation of multiple initial material station tables, one of the multiple initial material station tables is selected as the base material station table, and the base material station table is compared with the first material station table; wherein, the first material station table is any initial material station table other than the base material station table among the multiple initial material station tables, and the number of initial material station tables to be merged is determined based on the number of stations included in the pick and place machine set;

[0059] If the storage location column of the basic material station table and the first material station table have the same value but the material column has a different value, then 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.

[0060] Sixthly, embodiments of this application provide a pick-and-place machine, including a processor, a memory, a placement head, a feeder, and a scanner;

[0088] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0089] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities and do not necessarily imply a specific order or sequence, unless otherwise indicated. It should be understood that such terms can be used interchangeably where appropriate, for example, to implement the application in a sequence other than those given in the embodiments illustrated or described herein.

[0090] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

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

[0092] The terminology used in the embodiments of this application will be explained below.

[0093] SAP Systems, Applications, and Products: This is an enterprise management software that provides multiple modules including financial accounting, materials 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. By simultaneously considering the constraints of multiple limited capacity resources and according to various preset rules, it generates detailed plans through highly complex intelligent mathematical algorithms that repeatedly simulate, explore, optimize, and calculate.

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

[0096] The design concept of the embodiments of this application will be summarized below in conjunction with application scenarios.

[0097] In the traditional SMT assembly process, many small orders are generated. These small orders require a small number of components but a wide variety of types, often requiring frequent production changes. This not only affects production efficiency but also increases production costs.

[0098] In view of this, this application provides a method for merging material station tables for multiple types of surface mount products. This method merges material station tables based on a visual interface. For work orders producing multiple types of surface mount products, a query operation is performed on the interface to obtain and display initial material station tables for different types of surface mount products. Then, the displayed initial material station tables are merged. During the merging process, one initial material station table is selected as the base material station table. The base material station table is compared with the other initial material station tables one by one. When the values ​​in the location column are the same in the two tables but the values ​​in 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 base material station table, thereby merging the multiple initial material station tables into a single target material station table. When merging the materials required for various surface mount product types, the storage positions of the materials on the feeder are kept the same. This ensures that the placement head accurately picks up the required materials from the corresponding positions, guaranteeing normal production after merging. Furthermore, since the merged target material station list contains all the materials required for various surface mount product types, continuous production of various surface mount product types can be achieved when materials are put into the production line according to the target material station list, without the need for production changeover, thereby improving the production efficiency of SMT surface mount technology.

[0099] On the other hand, this application provides a production method for multi-pattern surface mount products. For different pattern surface mount products, after each barcode scan, a target material station table is obtained by merging the initial material station tables based on multiple pattern surface mount products. The online materials are then checked according to the target material station table. Since the target material station table contains all the materials required for multiple pattern surface mount products, after verification, the continuous production of different pattern surface mount products is automatically carried out without the need for production switching, thereby improving the production efficiency of SMT surface mount products.

[0100] See Figure 1This application provides a system architecture diagram for the material station list merging method. The system architecture comprises four parts: an information management and control system, an API gateway, a converged integration platform, and a database. The information management and control system is based on the mainstream MES in the PCBA industry and uses software development technology to implement the material station list merging function. The information management and control system mainly provides a UI interface for selecting, merging, and maintaining material station lists; automatically compares materials for selected material station lists and merges them based on the comparison results; stores the material station lists in the database; and connects to the service interface of the converged integration platform through the API gateway to obtain data. The obtained data includes, but is not limited to, placement work orders published by the APS system and bills of materials (BOMs) in SAP software. The API gateway is mainly used for communication between different systems and is an important tool for standardizing the application programming interface (API) between business systems and achieving standardized integration between business systems. The converged integration platform, as a centralized management and control platform for API services, is used for publishing and subscribing to service interfaces, supporting various business systems to publish services and call third-party services. Databases are used for storing and managing material station tables and BOMs, including but not limited to databases such as Oracle, MySQL, SQL Server, and DB2.

[0101] Optionally, the system architecture in this application may also include printing software, such as CodeSoft. 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 this application does not impose any restrictive requirements on the software technology for the material station table merging function. For example, it can be developed using the C# language on the .NET platform.

[0103] Taking the CM602 pick-and-place machine with four multi-functional placement heads as an example, such as... Figure 2 As shown, it contains 108 stations and can simultaneously install multiple feeders. These feeders are fixed on the feeding cart (i.e., the table cart) to provide materials to the pick and place machine in an orderly manner.

[0104] To enable mixed order production for SMT placement of different board types, the number of pick-and-place machines on the SMT production line can be configured according to the placement work order. The more pick-and-place machines there are, the more workstations there are, and the more board types can be placed simultaneously.

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

[0106] Taking the CM602 pick-and-place machine as an example, such as Figure 3 As shown, for the mixed-order production line for SMT assembly, the original two CM602 pick-and-place machines were increased to three, resulting in an additional 108 workstations. This allows for the simultaneous binding of materials from five different SMT board types. Each CM602 pick-and-place machine includes four multi-functional placement heads, capable of simultaneously picking up four materials from the feeders corresponding to different workstations and supplying them to the PCB board. The TRAY box functions similarly to a workstation; due to the different shapes and sizes of the materials, their storage positions on the feeders vary, corresponding to different workstations.

[0107] It should be noted that, Figure 2 and Figure 3 This is merely an example of a pick-and-place machine. This application does not impose any restrictions on the model of the pick-and-place machine, the type of feeder, or the number of additional pick-and-place machines. In actual SMT production lines, the selection can be made flexibly based on factors such as equipment cost and space.

[0108] For placement work orders of different types, based on the set of placement machines composed of multiple placement machines on the SMT placement production line, the movement path of the placement head to pick up the materials required for different types of placement products is determined, and the station layout sequence information is pre-generated according to the movement path and imported into the MES system.

[0109] In one example, to ensure placement efficiency, the station layout order can be determined based on the principle of shortest movement path. Specifically, according to the frequency of material usage and storage location on the feeder when placing different types of products, the stations included in the placement machine set are rearranged and reorganized to minimize the movement path of the placement head when picking up materials. The final station layout order information is then obtained and imported into the MES system.

[0110] As the basic data for SMT placement, the station table needs to be generated in advance for different placement work orders.

[0111] like Figure 4The diagram illustrates the initial material station table generation process. After different types of surface mount technology (SMT) work orders are entered into the APS system, the APS system schedules production processes for these work orders, generates shift production plans, and distributes these plans to the MES system via the API gateway interface on the integrated platform. The MES system, based on the part number of each SMT product type in the shift production plan, calls the SAP system through the integrated platform to obtain the corresponding BOM address. It then retrieves the bill of materials (BOM) for the corresponding SMT product type based on the BOM address and stores it locally. Combined with the imported station sorting information, the initial material station table for the corresponding SMT product type is generated.

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

[0113] S501: Obtain shift production plans generated from placement work orders based on various types of surface mount products.

[0114] The MES system obtains pre-generated shift production plans from the APS system through an integrated platform. These shift production plans contain the production sequence of various patch panel products. Therefore, the MES system can sequentially select the unique part number corresponding to each patch panel product type according to the production sequence, thereby generating an initial material station list in an orderly manner.

[0115] like Figure 5B As shown, this is the interface for the APS system to issue shift production plans to the MES system on the integrated platform.

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

[0117] In response to the generation of the current product part number, the MES system calls the SAP system through the integration platform to obtain the bill of materials corresponding to the current product part number and saves it locally in the MES system.

[0118] S503: Verify the locations of materials in the bill of materials against the locations of materials in the pre-imported station layout information, and generate an initial material station table.

[0119] The MES system ensures the accuracy of the generated initial material station list by verifying the material locations and station positions.

[0120] After generating initial material station tables for various patch panel products, store these initial material station tables in the database for later use.

[0121] Each type of surface mount product has an initial material station list containing the materials required for that type of surface mount product and their storage locations on the feeders. Therefore, multiple types of surface mount products can be produced based on multiple initial material station lists. However, considering that different types of surface mount products use different materials, generating the corresponding surface mount products according to multiple initial material station lists would involve a process of unloading materials from the previous type of surface mount product and loading materials for the next type, which is inefficient. Therefore, this application provides a method for merging material station lists for multiple surface mount products. Applied before surface mount production, this method merges multiple initial material station lists into one, thereby obtaining all the materials required for multiple types of surface mount products, reducing the number of changeovers and improving the production efficiency of SMT surface mount products.

[0122] See Figure 6 The method for merging material station lists for multi-pattern patch panels provided in this application embodiment mainly includes the following steps:

[0123] S601: In response to the surface mount product query operation, the initial material station table of the set of surface mount products to be produced is 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 surface mount products to be produced on the SMT production line in the toolbar. Different surface mount products have different surface mount layouts.

[0125] like Figure 7 As shown, when a user queries based on the production date of the patch, the main table area of ​​the interface displays the initial material station table of different patch product sets to be produced during this period.

[0126] It should be noted that, Figure 7 This is just one example; users can also search for surface mount products to be manufactured by entering product part number, product name, and other information.

[0127] S602: In response to a merge operation of multiple initial station tables, select one of the multiple initial station tables as the base station table.

[0128] The initial number of material stations to be merged is determined based on the number of stations included in the pick-and-place machine set. Specifically, the initial number of material stations to be merged cannot exceed the number of pattern types corresponding to the number of stations included in the pick-and-place machine set.

[0129] Taking a set of placement machines consisting of 3 CM602 placement units as an example, the number of stations it contains can produce 5 types of placement products at the same time. At this time, the initial material station tables of the 5 types of placement products can be merged, that is, the number of merged initial material station tables is 5.

[0130] In 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. The number of selected initial material station tables does not exceed the number of board types corresponding to the number of station positions contained in the pick and place machine set. Furthermore, in response to the merge operation of multiple initial material station tables in the merge area, one of the multiple initial material station tables is selected as the base material station table.

[0131] by Figure 7 For example, the user selects the first 5 initial material station tables in the main table area of ​​the interface. These 5 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 will automatically merge the 5 selected initial material station tables. During the merging process, the first initial material station table will be used as the base material station table.

[0132] It should be noted that the embodiments of this application do not impose restrictive requirements on the selection of the basic material station list. For example, the last initial material station list can also be used as the basic material station list.

[0133] In one example, in response to the selection of the initial material station list, the MES system can also display the details of the selected initial material station list in the sub-table area of ​​the interface. The material station list is displayed clearly through the visualization interface, making it easier for operators to view the material details of various types of patch products.

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

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

[0136] The storage location is listed as follows: Figure 7 The table column in the table. During the process of merging 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 (i.e., materials that differ from those in the basic material station table) are stored in the same position on the feeder, the placement head can correctly pick up the materials required for the corresponding pattern of the placement product in the first material station table.

[0137] In the embodiments of this application, the first material station table is any one of the multiple initial material station tables other than the basic material station table.

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

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

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

[0141] S605: Determine if all comparisons are complete. If not, return to S603; otherwise, end.

[0142] After comparing the basic material station table with the remaining initial material station tables one by one, the selected initial material station tables can be merged into a target material station table. The target material station table is then stored in the database with a new name (such as raw material table-HB) for material error prevention comparison during production. At the same time, the merged initial material station tables in the database are 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 embodiments of this application, the placement machines configured on the SMT production line are arranged in a specific layout. The material station table merging function of the MES system is developed using C# language on the .NET platform. In this way, before production, after the staff selects the material station table of different types of SMT products in the MES system and clicks the merge option, the MES system generates a new material station table through the background merging logic, ensuring accuracy. This realizes the one-click production change function of the material station table required for different types of SMT products.

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

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

[0149] In the embodiments of this application, for surface mount orders with small quantities and numerous layouts, an initial material station table for each layout type of surface mount product is generated based on the bill of materials corresponding to the surface mount work order and the station layout sequence information corresponding to the surface mount machine set. Each initial material station table contains the materials required for the corresponding layout type of surface mount product and the storage location of the materials on the feeder. If surface mount production is carried out directly using the initial material station table, it will involve the production transition process of unloading materials for the previous layout type of surface mount product and loading materials for the next layout type of surface mount product. Therefore, a query operation for the surface mount set to be produced is performed based on a visual interface. The initial material station table of the surface mount product set to be produced for different surface mount layout types is displayed in the main table area of ​​the interface, and the initial material station table of the surface mount product set to be produced for different surface mount layout types is obtained from the table. Multiple initial material station lists are selected and merged one by one. Materials with the same location column value but different material column values ​​from two different material station lists are merged into one material station list. This ensures that the placement head can accurately pick up materials during surface mount technology (SMT) production. Furthermore, since the merged target material station list contains materials required for various SMT product types, and the number of initial material station lists is determined based on the number of stations in the SMT machine set, the number of stations on the production line can meet the needs of simultaneous production of multiple SMT product types. Thus, the SMT machine set can produce multiple SMT product types at once based on the materials on the target material station list, effectively reducing changeover times and improving production efficiency. On the other hand, the station positions in the SMT machine set are determined based on the movement path of the placement head picking up materials; minimizing the movement path further improves the efficiency of SMT production.

[0150] In one example, the MES system can also be connected to a printer, such as... Figure 9 The image shows the printing interface for the material station details. After obtaining the target material station list, it can be compared with the bill of materials for the components to be manufactured, extracting key information about the materials with annotations. Based on this information, a material station detail list is generated and sent to the printer. Printing the material station detail list allows staff on the SMT production line to verify the information and prevent placement errors.

[0151] Optional material key information includes, but is not limited to, whether the material needs to be programmed and its mounting location.

[0152] In the embodiments of this application, since the merged target material station list contains the materials required for different types of patch products, multiple types of patches can be produced at once based on the merged target material station list.

[0153] See Figure 10This application provides a production method flow for multi-pattern surface mount products, applied to a surface mount machine. It assumes the target material station table is the result of merging the initial material station tables for the first and second products, containing the materials required for surface mount assembly of both products. The surface mount patterns for the first and second products 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 based on the first barcode.

[0155] S1002: Based on the target material station list, check whether all the materials required for the first product are online. If yes, proceed to S1003; otherwise, end.

[0156] S1003: Controls the placement head to pick up the material corresponding to the first product and place it.

[0157] Once the first product is mounted, the SMT production line can continue with the mounting process for the second product without interrupting the process.

[0158] S1004: Scan the second barcode of the second product and obtain the target material station table based on the second barcode.

[0159] S1005: Based on the target material station list, check whether all materials required for the second product are online. If yes, proceed to S1006; otherwise, end.

[0160] S1006: Control the placement head to pick up the material corresponding to the second product for placement.

[0161] In the embodiments of this application, on the SMT production line, the materials required for each product are compared one by one according to the merged target material station list. After ensuring that all materials are online, products of different surface mount types are generated continuously at one time. The whole process does not require production change, realizing efficient utilization of materials and a continuous and stable production process, effectively improving the efficiency of SMT surface mount.

[0162] See Figure 11This application provides a complete business process for merging material station lists and surface mount production. In the material station list merging section, the MES system obtains the shift production plan from the ASP system through the integration platform. Based on the product part numbers in the shift production plan, it obtains the corresponding bill of materials from the SAP system through the integration platform. Combined with the imported station layout sequence information, it generates initial material station lists for multiple surface mount product types and stores them in the database. For the set of surface mount products to be produced on the SMT production line, in response to the selection operation of multiple initial material station lists for surface mount products, the selected initial material station lists are merged with one click, and the merged target material station list is stored in the database. The MES system prints a material station detail containing key material information by calling the printer. In the surface mount production section, the pick-and-place machine retrieves the target material station list from the database for different surface mount product types and performs material online detection to ensure that all materials for different surface mount product types are accurately and completely online, achieving continuous production of different surface mount product types in one go.

[0163] This application embodiment merges the initial material station lists of various types of surface mount products, enabling the simultaneous production of multiple types of surface mount products on a single SMT production line, reducing the number of changeovers and improving production efficiency.

[0164] In actual SMT operations, when producing multi-type surface mount products based on the merged target material station list, the number of A-type changeovers can be reduced, saving more than 4 hours of changeover time per shift. The effect is significant and the reliability is strong.

If the storage location column values ​​of the base material station table and the first material station table are the same but the material column values ​​are different, then the material column values ​​of the first material station table are added to the material column of the base material station table to obtain the target material station table.
