[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-299721 Summary of the Invention [Problem to be solved by the invention]

[0004] There is a need for a system for integrated management of multiple processes for manufacturing metal-clad laminates. [Means for solving the problem]

[0005] A manufacturing management system according to one aspect of the present disclosure includes a database storing a management data set related to management of each of a plurality of processes for manufacturing a metal-clad laminate, and at least one processor accessing the database. In each management data set for the plurality of processes, a plan ID, which is an identifier identifying the processing unit at that process, one or more lot numbers, which are identifiers identifying the manufacturing unit of one or more types of objects related to that process, and one or more data items related to the quality at that process are associated with each other. Two management data sets corresponding to two consecutive processes arbitrarily selected from the plurality of processes are associated with each other by a common lot number, which is a lot number common to the two management data sets. Based on search conditions for the quality of the metal-clad laminate, the at least one processor searches at least two management data sets corresponding to two consecutive processes among the plurality of processes based on the common lot number of the two management data sets, and generates search results for the quality of the metal-clad laminate based on at least one of the two searched management data sets.

[0006] A manufacturing management method according to one aspect of the present disclosure is executed by a manufacturing management system including at least one processor. The manufacturing management method includes a step of accessing a database that stores a management data set related to the management of each of a plurality of processes for manufacturing a metal-clad laminate and performing a search process. In each management data set for the plurality of processes, a plan ID, which is an identifier identifying the processing unit at that process, one or more lot numbers, which are identifiers identifying the manufacturing unit of one or more types of objects related to that process, and one or more data items related to the quality at that process are associated with each other. Two management data sets corresponding to two consecutive processes arbitrarily selected from the plurality of processes are associated with each other by a common lot number, which is a lot number common to the two management data sets. The search process includes a step of searching at least two management data sets corresponding to two consecutive processes among the plurality of processes based on a search condition for the quality of the metal-clad laminate, based on the common lot number of the two management data sets, and a step of generating a search result for the quality of the metal-clad laminate based on at least one of the two searched management data sets.

[0007] A manufacturing management program according to one aspect of the present disclosure causes a computer to execute a step of accessing a database that stores management data sets related to the management of each of a plurality of processes for manufacturing a metal-clad laminate and performing a search process. In each management data set for the plurality of processes, a plan ID, which is an identifier identifying the processing unit in the process, one or more lot numbers, which are identifiers identifying the manufacturing unit of one or more types of objects related to the process, and one or more data items related to the quality of the process are associated with each other. Two management data sets corresponding to two consecutive processes arbitrarily selected from the plurality of processes are associated with each other by a common lot number, which is a lot number common to the two management data sets. The search process includes the steps of: searching at least two management data sets corresponding to two consecutive processes among the plurality of processes based on a search condition for the quality of the metal-clad laminate, using the common lot number of the two management data sets; and generating search results for the quality of the metal-clad laminate based on at least one of the two searched management data sets.

[0008] In this aspect, in each process for manufacturing a metal-clad laminate, a plan ID identifying the processing unit, a lot number identifying the manufacturing unit, and quality-related data items are associated with each other. Additionally, between any two consecutive processes within a process, both sets of control data are associated by a common lot number. Because multiple sets of control data corresponding to multiple processes are prepared in this way, a cross-sectional search of two or more sets of control data across multiple processes using the common lot number can be performed to generate search results regarding the quality of the metal-clad laminate. This database and search mechanism enable integrated management of multiple processes for manufacturing a metal-clad laminate. [Effects of the Invention]

[0011] Various examples of the present disclosure will be described in detail below with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are designated by the same reference numerals, and redundant description will be omitted.

[0012] [System Configuration] The manufacturing management system according to the present disclosure is a computer system for integrated management of multiple processes for manufacturing metal-clad laminates. An example of a metal-clad laminate is a copper-clad laminate. Traditionally, management of metal-clad laminate manufacturing has been performed on paper or by closed computer systems for each process. Therefore, tracing the quality of a metal-clad laminate required checking documents and comparing data obtained from multiple computer systems, which was time-consuming. The manufacturing management system includes a database that associates multiple management data groups corresponding to the multiple processes for manufacturing a metal-clad laminate, and performs searches using this database. This mechanism enables users of the manufacturing management system to trace the quality of a metal-clad laminate across multiple processes. Additionally, users can perform the tracing process in a short amount of time.

[0013] A manufacturing control system is composed of one or more computers. When multiple computers are used, these computers are connected via a communication network such as the Internet or an intranet to logically construct a single manufacturing control system.

[0014] A computer that makes up a manufacturing control system generally comprises hardware devices such as a processor, memory, and a communication interface. The processor is, for example, a CPU, and the memory is composed of flash memory, a hard disk, etc. Each function of the manufacturing control system is realized by the processor executing a program stored in the memory. The computer may also comprise input devices such as a keyboard and a mouse, and output devices such as a monitor and speakers.

[0015] A manufacturing management program for causing a computer to function as a manufacturing management system includes program code for implementing each functional module of the manufacturing management system. This manufacturing management program may be provided in a state where it is non-temporarily recorded on a tangible recording medium, such as a CD-ROM, DVD-ROM, or semiconductor memory. Alternatively, the manufacturing management program may be provided via a communications network as a data signal superimposed on a carrier wave. The provided manufacturing management program is recorded in memory, for example.

[0016] FIG. 1 illustrates the functional configuration of a manufacturing management system 1 according to an example. In this example, the manufacturing management system 1 includes a server 10 that executes a search process for the quality of metal-clad laminates and a database 20 that stores data used for the search. In this disclosure, the term "quality of metal-clad laminates" refers to a concept that encompasses the quality of the metal-clad laminates themselves, the quality of materials or intermediate products used to manufacture the metal-clad laminates, and the quality of the manufacturing environment for the metal-clad laminates. An example of the manufacturing environment is the operating status of the manufacturing equipment. In the example of FIG. 1, the server 10 is connected to the database 20 via a communication network; however, the database 20 may be provided within the server 10. The server 10 is further connected to one or more user terminals 30 via the communication network. The communication network connecting the devices may be constructed by including at least one of the Internet and an intranet, or may be constructed by other methods.

[0017] The server 10 includes a processor 101. In one example, the processor 101 functions as a search unit 11. The search unit 11 is a functional module that accesses the database 20, executes a search process based on search conditions received from a user terminal 30, and transmits search results to the user terminal 30.

[0018] The database 20 stores a group of management data relating to the management of each of a plurality of processes for manufacturing a metal-clad laminate. The database 20 may be realized by a single database management system, or may be realized by two or more database management systems working together.

[0019] The user terminal 30 is a computer used by a user of the manufacturing management system 1. The user terminal 30 may be various computers such as a personal computer, a workstation, a tablet terminal, a smartphone, or a wearable terminal. The user may be various people or groups involved in the manufacturing or distribution of metal-clad laminates, such as a manufacturing manager, a field worker, a logistics manager, or a sales manager.

[0020] [Management data set] 2 to 7, examples of management data groups for each process stored in database 20 will be described. In the following description, it is assumed that the production of a metal-clad laminate includes a blending / synthesis process for producing materials used to produce varnish, a varnish production process for producing varnish, a coating process for producing an insulating sheet by applying the varnish to a sheet material, and a lamination process for laminating a metal foil onto the insulating sheet to produce a metal-clad laminate.

[0021] 2 is a diagram showing an example of the relationship between management data groups among processes. In this example, database 20 stores management data group 21 for a blending / synthesis process, management data group 22 for a varnish manufacturing process, management data group 23 for a coating process, and management data group 24 for a lamination process.

[0022] In the management data group 21, a plan ID for the blending / synthesis process, a varnish material lot number, a base material lot number, and one or more data items related to quality in the blending / synthesis process are associated with each other. In this disclosure, "lot number" is used as an abbreviation for "lot number." The plan ID is an identifier that identifies the processing unit in the blending / synthesis process. The varnish material lot number is an identifier that identifies the production unit of the varnish material, which is the material used in producing the varnish. The base material lot number is an identifier that identifies the production unit of the base material, which is the material used in producing the varnish material. The quality in the blending / synthesis process includes at least one of the quality of the base material and the quality of the varnish material. Both the varnish material and the base material are objects related to the blending / synthesis process.

[0023] In the management data group 22, a plan ID for the varnish manufacturing process, a varnish material lot number, a varnish slot number, and one or more data items related to quality in the varnish manufacturing process are associated with each other. The plan ID is an identifier that identifies the processing unit in the varnish manufacturing process. The varnish slot number is an identifier that identifies the manufacturing unit of varnish. The quality in the varnish manufacturing process includes at least one of the quality of the varnish material and the quality of the varnish. Both the varnish material and the varnish are objects related to the varnish manufacturing process.

[0024] In the management data group 23, a plan ID for the coating process, a varnish slot number, a sheet lot number, and one or more data items related to quality in the coating process are associated with each other. The plan ID is an identifier that identifies the processing unit in the coating process. The sheet lot number is an identifier that identifies the manufacturing unit of the insulating sheet. The quality in the coating process includes at least one of the quality of the varnish material and the quality of the insulating sheet. Both the varnish and the insulating sheet are objects related to the coating process.

[0025] In the management data group 24, the plan ID for the lamination process, the sheet lot number, the collating lot number, and one or more data items related to quality in the lamination process are associated with each other. The plan ID is an identifier that identifies the processing unit in the lamination process. The collating lot number is an identifier that identifies the manufacturing unit of the metal-clad laminate. The quality in the lamination process includes at least one of the quality of the insulating sheet and the quality of the metal-clad laminate. Both the insulating sheet and the metal-clad laminate are objects related to the lamination process.

[0026] In this disclosure, "processing unit in a process" refers to a unit of management of processing or production in a process. "Manufacturing unit of an object" refers to a unit of management of an object, also called a "lot." The processing unit and manufacturing unit may have a one-to-one relationship, a one-to-n relationship, or an n-to-1 relationship, where n is an integer of 2 or greater.

[0027] As shown in FIG. 2, in each management data group for a plurality of processes, the plan ID for that process, one or more lot numbers related to that process, and one or more data items related to quality for that process are associated with each other.

[0028] The compounding / synthesis process, varnish production process, coating process, and lamination process are performed in this order. The four management data groups corresponding to these four processes are associated with each other based on their order. Management data group 21 and management data group 22 are associated with each other by the varnish material lot number. Management data group 22 and management data group 23 are associated with each other by the alligator slot number. Management data group 23 and management data group 24 are associated with each other by the sheet lot number. In this way, two management data groups corresponding to two consecutive processes arbitrarily selected from multiple processes are associated with each other by a common lot number, which is a lot number common to the two management data groups. In the example of Figure 2, the lot numbers (i.e., varnish material lot number, alligator slot number, and sheet lot number) of the products (objects) manufactured in the previous process and used as materials in the next process function as the common lot number.

[0069] The material table 241, the completion table 242, the material table 243, the completion table 245, the material table 246, the completion table 247, the material table 249, the completion table 250, the material table 251, the completion table 253, and the measurement table 254 are related to each other by plan ID. The completion table 242, the material table 243, the inspection table 244, the completion table 245, the material table 246, the completion table 247, the material table 249, the completion table 250, the material table 251, the material inspection table 252, and the completion table 253 are related to each other by collation lot number. The completion table 247 and the equipment table 248 are related to each other by press number.

[0070] As shown in Figure 2, management data groups 21 to 24 are associated with each other using three common lot numbers: varnish material lot number, varnish slot number, and sheet lot number, making it possible for server 10 to search across these management data groups.

[0071] Three consecutive processes arbitrarily selected from the compounding / synthesis process, varnish production process, coating process, and lamination process are referred to as the first process, second process, and third process, in that order. In this case, the management data group for the first process includes a first lot number that identifies the production unit of the first product, which is the object produced in the first process. The management data group for the second process includes, as one or more lot numbers, the first lot number and a second lot number that identifies the production unit of the second product, which is the object produced in the second process. The management data group for the third process includes, as one or more lot numbers, the second lot number. The first lot number is a common lot number that associates the management data group for the first process with the management data group for the second process. The second lot number is a common lot number that associates the management data group for the second process with the management data group for the third process.

[0072] As an example, assume that the varnish production process, coating process, and lamination process are the first process, the second process, and the third process, respectively. In this case, the management data group 22 for the varnish production process includes a varnish slot number that identifies the production unit of the varnish (first product) produced in the varnish production process. The management data group 23 for the coating process includes a varnish slot number and a sheet lot number that identifies the production unit of the insulating sheet (second product) produced in the coating process. The management data group 24 for the lamination process includes a sheet lot number. The varnish slot number is a common lot number that associates the management data group 22 and the management data group 23 with each other. The sheet lot number is a common lot number that associates the management data group 23 and the management data group 24 with each other.

[0073] [System Operation] An example of processing by the manufacturing management system 1 and an example of a manufacturing management method according to the present disclosure will be described with reference to Fig. 8. Fig. 8 is a flowchart showing this example as a processing flow S1.

[0074] In step S11, the search unit 11 receives search conditions for the quality of metal-clad laminates from the user terminal 30. The user operates the user terminal 30 to input the search conditions. In response to the user operation, the user terminal 30 transmits the search conditions to the server 10. The search unit 11 receives the search conditions.

[0075] In step S12, the search unit 11 searches the database 20 based on the search conditions and generates search results. The search unit 11 references at least one of the management data groups 21 to 24 based on the search conditions. In one example, the search unit 11 searches at least two management data groups corresponding to two consecutive processes based on a common lot number shared by the two management data groups. For example, the search unit 11 may cross-search the management data groups 21 and 22 based on the varnish material lot number, cross-search the management data groups 22 and 23 based on the varnish slot number, or cross-search the management data groups 23 and 24 based on the sheet lot number. The search unit 11 may search three or more management data groups corresponding to three or more consecutive processes based on two or more common lot numbers. As another example, the search unit 11 may search only one management data group.

[0076] The search unit 11 generates search results for the quality of the metal-clad laminate based on at least one of the one or more searched control data groups. The search unit 11 may generate search results based on at least one of two control data groups corresponding to two or three consecutive processes among the control data groups 21 to 24. Alternatively, the search unit 11 may generate search results based on all of the control data groups 21 to 24. The quality indicated by the search results is represented by the quality of at least one process. For example, the search unit 11 generates search results including the quality of at least one of the base material, the varnish material, the varnish, the insulating sheet, and the first to fourth intermediate products. Alternatively, the search unit 11 may generate search results including the quality of the metal-clad laminate itself, or the quality of the manufacturing environment.

[0077] In step S13, the search unit 11 transmits the search results to the user terminal 30. The user terminal 30 receives and displays the search results, allowing the user to check the quality of the metal-clad laminate.

[0078] The manufacturing management system 1 executes process flow S1 each time search conditions are sent from the user terminal 30 to the server 10. Using the manufacturing management system 1, a user can search for the quality of metal-clad laminates from various perspectives while tracing multiple processes from a certain process upstream or downstream. For example, a user can trace the quality of an insulating sheet, varnish, varnish material, or base material using a lot number (collating lot number) that indicates the manufacturing unit of a metal-clad laminate. Alternatively, a user can trace the quality of a metal-clad laminate using a lot number that indicates the manufacturing unit of a base material, varnish material, varnish, or insulating sheet.

[0079] [Variations] The technology according to the present disclosure has been described in detail above based on various examples. However, the present disclosure is not limited to the above examples. The technology according to the present disclosure can be modified in various ways without departing from the spirit of the present disclosure.

[0080] In the above example, the production of a metal-clad laminate includes a compounding / synthesizing step, a varnish-making step, a coating step, and a lamination step. However, the types and combinations of the multiple steps are not limited to this example. For example, the multiple steps may include a varnish-making step, a coating step, and a lamination step without including a compounding / synthesizing step. Alternatively, the multiple steps may include other steps such as packaging and final inspection.

[0081] In the above example, the manufacturing management system is provided as a server-side configuration in a client-server system, for example, as a cloud system. As another example, the manufacturing management system may be implemented on a stand-alone computer. Alternatively, the manufacturing management system may be implemented on a user terminal that can access the database via a communication network.

[0082] The processing steps of the method executed by at least one processor are not limited to the above examples. For example, some of the above steps may be omitted, or the steps may be executed in a different order. Furthermore, any two or more of the above steps may be combined, or some of the steps may be modified or deleted. Alternatively, other steps may be executed in addition to the above steps.

[0083] In the present disclosure, when comparing the magnitude of two numerical values, either of the two criteria "greater than or equal to" and "greater than" may be used, or either of the two criteria "less than or equal to" and "less than" may be used.

[0084] In this disclosure, the expression "at least one processor executes a first process, executes a second process, ... executes an nth process" or a corresponding expression indicates a concept including a case where the entity executing the n processes from the first process to the nth process, i.e., the processor, changes midway through. In other words, this expression indicates a concept including both a case where all n processes are executed by the same processor and a case where the processor changes among the n processes according to an arbitrary policy.

(Appendix 5) a step of causing a computer to execute a search process by accessing a database that stores a group of management data relating to management of each of a plurality of processes for manufacturing a metal-clad laminate; In each management data group of the plurality of processes, a plan ID which is an identifier for identifying a processing unit in the process, one or more lot numbers which are identifiers for identifying a manufacturing unit of one or more types of object related to the process, and one or more data items related to quality in the process are associated with each other; two management data groups corresponding to two consecutive processes arbitrarily selected from the plurality of processes are associated with each other by a common lot number that is the lot number common between the two management data groups; The search process a step of searching, based on a search condition for quality of the metal-clad laminate, for at least two of the management data groups corresponding to two consecutive processes among the plurality of processes, based on the common lot number of the two management data groups; generating a search result regarding the quality of the metal-clad laminate based on at least one of the two searched management data groups; Including, Manufacturing Management Program.

[0086] According to Supplements 1, 4, and 5, in each process for manufacturing a metal-clad laminate, a plan ID identifying the processing unit, a lot number identifying the manufacturing unit, and quality-related data items are associated with each other. Additionally, between any two consecutive processes within a process, both sets of control data are associated by a common lot number. Because multiple control data sets corresponding to multiple processes are prepared in this way, a common lot number can be used to cross-search two or more control data sets across multiple processes to generate search results for the quality of the metal-clad laminate. This database and search mechanism enable integrated management of multiple processes for manufacturing a metal-clad laminate. For example, a user can quickly trace the quality of a metal-clad laminate across multiple processes.

[0087] According to Appendix 2, the lot number of the product manufactured in the previous process and used as a material in the next process functions as a common lot number. By using the lot number of the product (object) passed from the previous process to the next process as a common lot number, groups of management data are linked to each other so as to match the flow of the actual manufacturing process. This mechanism makes it possible to provide a database designed to match human intuition.

[0088] According to Appendix 3, the varnish production process, coating process, and lamination process, which are the main processes in the manufacture of metal-clad laminates, can be managed in an integrated manner. In addition, a mechanism can be provided for flexibly searching for the quality of the varnish and insulating sheet, which directly affect the quality of the metal-clad laminate, as well as the quality of the metal-clad laminate itself.
