Modes for Carrying Out the Invention

[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The configurations, shapes, etc. described below are examples for explanation, and can be appropriately changed according to the specifications of the component mounting system, component mounting apparatus, and management computer. In the following, corresponding elements in all the drawings are denoted by the same reference numerals, and redundant explanations are omitted.

[0013] First, with reference to FIG. 1, the configuration of the component mounting system 1 will be described. The component mounting system 1 has a function of mounting components on a substrate to produce a mounted substrate. In the present embodiment, a configuration is adopted in which a plurality (here, three) of component mounting lines 4 are connected to a management computer 3 via a communication network 2. The operations on each component mounting line 4 are managed by the management computer 3. Note that the number of component mounting lines 4 is not limited to three, and may be one, two, or four or more.

[0014] The management computer 3 has a function of creating data and parameters necessary for the operation of the production facilities provided in each component mounting line 4 and transmitting them to each production facility. Further, data such as the operation status and work history of each production facility are transmitted from each production facility to the management computer 3. In addition, the management computer 3 has a function of creating component data, production data, etc. used in the production facilities of the component mounting line 4. Note that the component mounting system 1 may be provided with a line management computer for each component mounting line 4, and the management computer 3 and each production facility may transmit and receive data via the line management computer.

[0015] In FIG. 1, the component mounting line 4 has a configuration in which a substrate supply device M1, a substrate delivery device M2, a solder printing device M3, component mounting devices M4 and M5, a reflow device M6, and a substrate recovery device M7 are connected. The substrate supplied by the substrate supply device M1 is carried into the solder printing device M3 via the substrate delivery device M2, and a solder printing operation is performed here to screen-print cream solder for component bonding on the substrate.

[0016] The substrate after solder printing is sequentially transferred to the component mounting devices M4 and M5, where component mounting operations for mounting components on the substrate after solder printing are performed. The component mounting devices M4 and M5 take out the components supplied by the feeder by vacuum suction with a nozzle of the mounting head based on the operation parameters included in the component data set for each component to be mounted on the substrate. Then, the component recognition camera images the state of the component held by the nozzle and mounts it at the mounting angle designated for the mounting position on the substrate. The component mounting devices M4 and M5 are equipped with a plurality of sensors, and work mistakes and operation errors in the component mounting operations, such as the suction operation in which the nozzle sucks the component and the component recognition operation in which the component recognition camera images and recognizes the taken-out component, are monitored. Note that the mounting head may mount the component at the mounting position on the substrate by a chuck unit that grips the component in addition to the nozzle.

[0017] The substrate after component mounting is carried into the reflow device M6, where it is heated according to a predetermined heating profile, causing the cream solder for component bonding to melt and solidify. As a result, the components are soldered to the substrate, and the mounting substrate with the components mounted on the substrate is completed and recovered by the substrate recovery device M7.

[0018] Next, with reference to FIG. 2, the configuration of the information processing system of the management computer 3 will be described. Here, among the multiple functions of the management computer 3, the configuration regarding the function of creating and managing component data including the operation parameters used in the component mounting operations by the component mounting devices M4 and M5 will be described. That is, the management computer 3 is a component data management device that manages component data in which operation parameters, which are the operation conditions for the component mounting devices M4 and M5 to mount components on the substrate, are associated with the component information of the components.

[0019] The management computer 3 includes a processing unit 10, a storage unit 20 that is a storage device, an input unit 30, a display unit 31, and a communication unit 32. Note that the management computer 3 does not necessarily need to be configured by a single computer and may be configured by multiple devices. For example, all or part of the storage unit 20 and the processing unit 10 may be provided in the cloud via a server.

[0020] In FIG. 2, the input unit 30 is an input device such as a keyboard, a touch panel, or a mouse, and is used when an operation command or data is input. The display unit 31 is a display device such as a liquid crystal panel, and displays various data stored in the storage unit 20, and also displays various information such as an operation screen and an input screen for the operation by the input unit 30. The communication unit 32 is a communication interface, and performs data transmission and reception with production facilities (component mounting devices M4 and M5) constituting the component mounting line 4 via the communication network 2.

[0021] The processing unit 10 is a data processing device such as a CPU, and includes an actual result acquisition unit 11, a learning information creation unit 12, a learning unit 13, a parameter estimation unit 14, a calculation unit 15, an extraction unit 16, a parameter comparison unit 17, a display processing unit 18, and a parameter update unit 19 as internal processing units. The storage unit 20 stores a production data library 21, a component library 22, actual result information 23, learning information 24, a learning model 25, estimated operation parameters 26, production time information 27, production improvement value information 28, extraction operation parameters 29, and the like.

[0022] In FIG. 2, in the production data library 21, production data used in the production of the mounting substrate by the component mounting devices M4 and M5 is stored for each production model name of the mounting substrate. The production data includes a component name that identifies the component mounted on the substrate, a component code that associates the component with the component data in the component library 22, the mounting position and mounting angle of the component on the substrate, a component arrangement indicating the position of the feeder that supplies the component in the component mounting devices M4 and M5, a nozzle arrangement indicating the position of the nozzle that adsorbs the component in the mounting head, and the like. The component library 22 stores a plurality of component data in which operation parameters are associated with component information. The component data is associated with the production data in the production data library 21 by a component data code.

[0023] Referring now to FIG. 3, an example of the component data 33 included in the component library 22 will be described. The component data 33 is associated with the production data by the "component n" (component data code) included in the component data 33 and the component data code of the production data included in the production data library 21. In this example, the component library 22 stores the component data 33 of a plurality of types of components having component data codes of n = 1, 2, 3, ···. In the component data 33, component information 34 and operation parameters 35 are defined as major classification items.

[0024] The component information 34 is information indicating attributes unique to the component. Here, as intermediate classification items, "product name" 34a, "shape" 34b, "size" 34c, and "component parameters" 34d are exemplified. The "product name" 34a is information for identifying the component, and the "product number" assigned for management by the component manufacturer or the company itself is defined as a minor classification item. The "shape" 34b is information regarding the shape of the component, and the "shape" indicating the outer shape of the component by shape classification such as rectangular or cylindrical, the drawing showing the shape of the component, and the information specifying the image information are defined as minor classification items.

[0025] In the "size" 34c, as minor classification items, "outer dimensions" indicating the size of the component, "electrode position" indicating the number and position (spacing) of the electrodes (leads) formed on the component, etc. are defined. The "component parameters" 34d are attribute information of the component, and as minor classification items, "component type" indicating the type of the component, "polarity presence or absence" indicating the presence or absence of directionality in the outer shape of the component, "polarity mark" indicating the shape of the mark attached to the component when there is polarity, "mark position" indicating the position of the mark when there is a polarity mark, etc. are defined. Thus, the component information 34 includes at least one of the items such as the dimensions of the component, the number of leads, the lead pitch, the lead length, the lead width, the component height (size 34c), the shape data (shape 34b), and the component identification number (product name 34a).

[0026] In FIG. 3, the operation parameter 35 is a control parameter (operation condition) used to control the component mounting apparatuses M4 and M5 disposed on the component mounting line 4 when performing a component mounting operation on the components specified in the component data 33. Here, as intermediate classification items, “nozzle setting” 35a, “speed parameter” 35b, “recognition” 35c, “adsorption” 35d, and “mounting” 35e are exemplified.

[0027] “Nozzle setting” 35a is data regarding the suction nozzle used when sucking and holding the component, and “nozzle” that specifies the type of suction nozzle that can be selected as a sub-classification item is defined. “Speed parameter” 35b is a control parameter regarding the moving speed of the suction nozzle in the operation of taking out the component by the suction nozzle and mounting it on the substrate. These control parameters include, as sub-classification items, “adsorption speed” and “adsorption holding time” when sucking and holding the component, and “mounting speed” and “mounting holding time” when mounting the held component on the substrate.

[0028] In FIG. 3, “recognition” 35c is a parameter regarding the execution of a recognition process of imaging and recognizing the component taken out from the component supply unit by the suction nozzle by the component recognition camera. These parameters include, as sub-classification items, “camera type” that specifies the type of camera used for imaging, “lighting mode” that indicates the mode of lighting used during imaging, and “recognition speed” when recognizing the image acquired by imaging.

[0029] "Suction" 35d is a control parameter related to the suction operation when taking out components from the component supply unit by the suction nozzle. These control parameters include, as sub-classification items, "Suction Position X", "Suction Position Y", etc., which indicate the suction position offset when landing the suction nozzle on the component. "Mounting" 35e is a control parameter related to the mounting operation of moving the mounting head holding the component by the suction nozzle to the substrate and causing the suction nozzle to move up and down to mount the component on the substrate. These control parameters include, as sub-classification items, "Mounting Load", which is the load for pressing the component against the substrate when lowering the suction nozzle to land the component on the substrate.

[0030] In this way, the operation parameter 35 includes at least one of the parameters for moving the component (such as the speed parameter 35b), the parameters for holding the component (such as the nozzle setting 35a, the speed parameter 35b, suction 35d, etc.), and the parameters for photographing the component (such as recognition 35c, etc.). Also, the operation parameter 35 may be changed in order to change the types of component mounting devices M4 and M5, the material of the substrate, the electrodes of the substrate, etc., or to improve the mounting quality and the mounting error rate, even if the "Product Name" 34a of the component is the same, that is, the component information 34 is the same.

[0031] When changing the operation parameter 35 of the component, component data 33 is created (updated) by associating the changed operation parameter 35 without changing the component information 34. At this time, a new code is assigned to "Component n" (component data code) of the component data 33 to distinguish it from the operation parameter 35 before correction. In this way, the component data 33 has the operation parameter 35, which is the operation condition for the component mounting devices M4 and M5 to mount the component on the substrate, associated with the component information 34 indicating the unique attributes of the component.

[0032] The component data 33 in the component library 22 (database) is transmitted together with the production data in the production data library 21 to the component mounting devices M4 and M5 on the component mounting line 4 and is used for the production of the mounting substrates in the component mounting devices M4 and M5. Hereinafter, the operation parameters used in the production by the component mounting devices M4 and M5 are referred to as "first operation parameters". That is, the first operation parameters of the first component mounted on the substrate in the component mounting devices M4 and M5 are stored on the database (component library 22) as the operation parameters used in the component mounting devices M4 and M5. Note that the component library 22 may include, in addition to the component data 33 used in the component mounting system 1 of its own factory, the component data 33 used in the component mounting system 1 of another factory and a database prepared in advance by an EDA (Electronic Design Automation) vendor.

[0033] In FIG. 2, the performance acquisition unit 11 acquires the performance of the component mounting operation from the component mounting devices M4 and M5 provided on each component mounting line 4. The performance of the component mounting operation includes information such as the production start date and time, the production end date and time, the number of produced sheets, the number of work mistakes, the mistake rate (frequency), the number of operation errors and the details thereof. The performance acquisition unit 11 stores, in the storage unit 20 as performance information 23, the acquired information in association with the information identifying the component mounting devices M4 and M5 that have performed the component mounting operation, the production data, and the component data 33 including the first operation parameters. That is, the first operation parameters are stored on the database (storage unit 20) in association with the performance information in the component mounting devices M4 and M5. Note that the performance acquisition unit 11 may acquire operation defect information from a substrate inspection device (not shown) provided on the component mounting line 4 that inspects the substrate state after the component mounting operation, in addition to the component mounting devices M4 and M5.

[0034] The learning information creation unit 12 creates, based on the performance information 23 and the component library 22, learning information 24 in which information regarding the first operation parameters, such as the first operation parameters of the first component with production performance, the component information 34 of the first component, and the performance of the component mounting operation, are associated, and stores the learning information 24 in the storage unit 20.

[0035] In FIG. 2, the learning unit 13 uses the learning information 24 as teaching data to generate a learning model 25 that shows the relationship between the operation parameters 35 and the component information 34 described later by a learning algorithm using machine learning or the like. As the learning algorithm, a neural network (including deep learning using a multi-layer neural network), genetic programming, decision tree, Bayesian network, support vector machine (SVM), or the like can be used. The generated learning model 25 is stored in the storage unit 20.

[0036] The parameter estimation unit 14 estimates the operation parameters 35 of the first component based on the generated learning model 25 and the component information 34 of the first component. The operation parameters 35 estimated by the parameter estimation unit 14 are stored in the storage unit 20 as estimated operation parameters 26 (second operation parameters).

[0037] Here, with reference to FIG. 4, an operation parameter estimation method for estimating the estimated operation parameters 26 (second operation parameters) by the component data management device (management computer 3) will be described. First, the learning information creation unit 12 creates learning information 24 by associating the component information 34, operation parameters 35 (first operation parameters), and performance information of the same component from the component library 22 and the performance information 23 stored in the storage unit 20 (ST1: learning information creation step).

[0038] For example, the learning information creation unit 12 creates teacher data in which the component information 34 and operation parameters 35 of a component whose product name 34a included in the component data 33 is "D1" (hereinafter simply referred to as "component D1", etc.) are associated with the performance information of component D1 mounted by the component mounting devices M4 and M5 included in the performance information 23, and stores it as the learning information 24.

[0039] In FIG. 4, next, the learning unit 13 generates a learning model 25 that indicates the relationship between the operation parameters 35 and the component information 34 based on the learning information 24 (ST2: learning process). The created learning model 25 is stored in the storage unit 20. Next, the parameter estimation unit 14 estimates (calculates) the estimated operation parameters 26 (second operation parameters) of the first component from the component information 34 of the first component using the generated learning model 25 (ST3: operation parameter estimation process). The estimated estimated operation parameters 26 are stored in the storage unit 20.

[0040] For example, the estimated operation parameters 26 (recommended values) for improving the productivity and mounting quality of the component mounting work of components with implementation results, and the estimated operation parameters 26 (expected values) of new components are calculated. In the example of FIG. 4, the parameter estimation unit 14 calculates the estimated operation parameters 26 (second operation parameters) recommended from the component information 34 of the component D1 with implementation results included in the component library 22 using the learning model 25.

[0041] In FIG. 2, the calculation unit 15 calculates the first production time when the first component is mounted on the substrate using the actual value of the operation parameters 35 (first operation parameters) of the first component included in the component data 33 used in production, by simulation mimicking the operations of the component mounting apparatuses M4 and M5, or from the production results included in the actual result information 23. Further, the calculation unit 15 calculates the second production time when the first component is mounted on the substrate using the estimated operation parameters 26 (second operation parameters) which are the recommended values estimated using the learning model 25, by simulation mimicking the operations of the component mounting apparatuses M4 and M5.

[0042] In the simulation that mimics the operations of component mounting devices M4 and M5, based on the component placement and nozzle placement of the production data stored in the production data library 21, and the operation parameters 35 (speed parameters 35b) of the component data 33 stored in the component library 22, etc., the time it takes for the mounting head to pick up a component from the feeder and mount it at the mounting position on the substrate is calculated. The calculated first production time and second production time are stored in the storage unit 20 as production time information 27.

[0043] Furthermore, based on the first production time and the second production time, the calculation unit 15 calculates a production improvement value expected when the operation parameter 35 is updated from the actual value to the recommended value. For example, as the production improvement value, an improvement rate representing the shortening of the production time ((first production time - second production time) / first production time) is calculated. The calculation unit 15 calculates, in addition to the improvement rate when all of the second operation parameters are replaced with the first operation parameters, the item-by-item improvement rate when one sub-classification item among the second operation parameters is replaced with the first operation parameter. The calculated production improvement value is stored in the storage unit 20 as production improvement value information 28. Note that the production improvement value calculated by the calculation unit 15 is not limited to the improvement rate of the production time, and may be, for example, an improvement value (improvement rate) of quality based on mounting defects.

[0044] In FIG. 2, the extraction unit 16 extracts the first operation parameter of the components whose component information 34 is similar or identical as the extraction operation parameter 29 from among the first operation parameters (operation parameters 35) of the plurality of components stored in the component library 22. Specifically, first, the extraction unit 16 extracts similar or identical component information 34 from the degree of match of at least one item of the component information 34 (see the sub-classification items in FIG. 3). Next, the extraction unit 16 extracts the first operation parameter associated with the component information 34 as the extraction operation parameter 29. The extracted extraction operation parameter 29 is stored in the storage unit 20.

[0045] In FIG. 2, the parameter comparison unit 17 compares two operation parameters 35 to determine whether the sub-classification items match or do not match. For example, the parameter comparison unit 17 compares the first operation parameter stored corresponding to the first component with the second operation parameter (estimated operation parameter 26) of the first component estimated by the parameter estimation unit 14, and extracts the matching sub-classification items. Alternatively, the parameter comparison unit 17 compares the first operation parameter stored corresponding to the first component with the first operation parameter (extracted operation parameter 28) of the component similar to the first component extracted by the extraction unit 16, and extracts the matching sub-classification items.

[0046] In addition, the parameter comparison unit 17 calculates an index indicating the degree of match of the sub-classification items of the operation parameters 35 to be compared. For example, the parameter comparison unit 17 calculates the ratio of the number of matching sub-classification items to the total number of sub-classification items (number of matching items / total number of items) as an index indicating the degree of match.

[0047] In FIG. 2, the display processing unit 18 displays a list display screen that displays, in the form of a list, the components for which the estimated operation parameter 26 (second operation parameter) has been calculated based on the production improvement value (production improvement value information 28). The calculation of the estimated operation parameter 26 is performed, for example, when creating production data for a newly produced mounting substrate, for all the components mounted on the mounting substrate. Here, referring to FIG. 5, the list display screen 40 displayed by the display processing unit 18 on the display unit 31 will be described. The list display screen 40 is displayed for the purpose of enabling an administrator to easily perform a study on appropriately changing the operation parameters of the components mounted on the mounting substrate to improve productivity when newly producing the mounting substrate.

[0048] In FIG. 5, on the list display screen 40, a component list display frame 41, a detailed display button 42, an update button 43, and a cancel button 44 are displayed. In the component list display frame 41, a determination display column 41a, a component name display column 41b, an improvement rate display column 41c, a shape display column 41d, a component type display column 41e, a size display column 41f, an up / down scroll bar 41g, and a left / right scroll bar 41h are displayed.

[0049] In the part name display column 41b, the part name of the component for which the estimated operation parameter 26 is calculated (the "product name" 34a of the component information 34) is displayed. In the improvement rate display column 41c, the improvement rate (production improvement value information 28) predicted when the operation parameter 35 (first operation parameter) included in the component data 33 stored in the component library 22 is replaced with the estimated operation parameter 26 (second operation parameter) and updated by the calculation unit 15 is displayed.

[0050] The components displayed in the component list display frame 41 are sorted in descending order of the improvement rate. That is, the display unit 31 lists and displays the components with a large production improvement value (production improvement value information 28) when the second operation parameter (estimated operation parameter 26) is replaced with the first operation parameter (operation parameter 35 associated with the component data 33) and updated. Note that the improvement rate by item may be displayed in the improvement rate display column 41c. That is, the display unit 31 may list and display the components with a large production improvement value when any item of the second operation parameter (sub-category item of the operation parameter 35) is replaced with the first operation parameter and updated.

[0051] In FIG. 5, in the shape display column 41d, the shape data of the component (the "shape" 34b of the component information 34) is displayed. "Box type" indicates that the shape of the component is a chip component with a substantially rectangular parallelepiped shape. In the component type display column 41e, the component type of the component (the "component parameter" 34d of the component information 34) is displayed. "Capacitor" indicates that the component is a capacitor, and "Resistor" indicates that the component is a resistor. In the size display column 41f, the outer dimensions of the component (the "size" 34c of the component information 34) are displayed. Here, L (length), W (width), and T (height) are displayed as the outer dimensions.

[0052] When the administrator operates the vertical scroll bar 41g through the input unit 30, the parts displayed in the parts list display frame 41 are changed. Also, when the administrator operates the horizontal scroll bar 41h through the input unit 30, the information of the parts displayed in the parts list display frame 41 (such as the items of the part information 34) is changed. Further, when the administrator selects any one of the parts displayed in the parts list display frame 41 through the input unit 30 and operates the detailed display button 42, the screen transitions to an operation parameter update determination screen for the selected part, which will be described later. In this example, part D1 is selected. On the operation parameter update determination screen, the administrator sets (determines) whether to replace the operation parameters with the estimated operation parameters 26 (the second operation parameters), and the items to be replaced, etc.

[0053] In FIG. 5, in the determination display column 41a, it is displayed whether the determination by the operation parameter update determination screen has been completed. "Completed" indicates that the determination has been completed. When the update button 43 is operated, the parameter update unit 19 replaces the second operation parameter (estimated operation parameter 26) selected to be updated on the operation parameter update determination screen with the first operation parameter currently in use and updates (creates) the part data 33. At this time, in order to distinguish from the operation parameter 35 before correction, part data 33 with a new code assigned to "part n" (part data code) is created. When the cancel button 44 is operated, the operation parameters are not updated and the screen transitions to the previous screen.

[0054] Next, with reference to FIG. 6, the operation parameter update determination screen 45 displayed by the display processing unit 18 on the display unit 31 will be described. The operation parameter update determination screen 45 shown in FIG. 6 shows an example where, after part D1 is selected on the list display screen 40 shown in FIG. 5, the detailed display button 42 is operated and displayed.

[0055] In FIG. 6, on the operation parameter update determination screen 45, a component name display column 46, an operation parameter display frame 47, an all select button 48, an all deselect button 49, an update button 50, a cancel button 51, and an index display column 52 are displayed. In the component name display column 46, the component name (here, "D1") of the component corresponding to the operation parameter displayed in the operation parameter display frame 47 is displayed. In the operation parameter display frame 47, an item display column 47a, a current value display column 47b, a recommended value display column 47c, an update setting column 47d, an improvement rate display column 47e, and a scroll bar 47f are displayed. By operating the scroll bar 47f with the input unit 30, the operation parameters and the like displayed in the operation parameter display frame 47 are changed.

[0056] In the item display column 47a, items corresponding to the sub-items of the operation parameter 35 shown in FIG. 3 are displayed. In the current value display column 47b, the operation parameters (first operation parameters) of the component D1 currently used in the component mounting devices M4 and M5 stored in the component library 22 are displayed. In the recommended value display column 47c, the operation parameters (second operation parameters) of the component D1 estimated by the parameter estimation unit 14 stored in the estimated operation parameter 26 are displayed.

[0057] In FIG. 6, in the update setting column 47d, check buttons corresponding to the items in the item display column 47a are displayed. The check buttons are displayed for the items of the operation parameter 35 for which it is determined by the parameter comparison unit 17 that the current value and the recommended value do not match. Also, in the operation parameter display frame 47, the non-matching items are displayed separately from the matching items. In this example, the columns of "mounting speed" and "automatic teach of suction position" are enclosed by dashed lines H1 and H2 for distinction. The administrator operates the input unit 30 to input (select) a check in the check button for the item for which the current value is to be replaced with the recommended value for update. When the all select button 48 is operated, all the check buttons are selected. Also, when the all deselect button 49 is operated, the selection of all the check buttons is cancelled.

[0058] In the improvement rate display column 47e, the improvement rate (production improvement value information 28) expected when the operation parameter 35 calculated by the calculation unit 15 is updated from the actual value to the recommended value is displayed. As a result, the administrator can select the item of the recommended value to be replaced and updated while referring to the improvement rate when replacing it with the recommended value (the second operation parameter).

[0059] In FIG. 6, in the index display column 52, the number of items (index indicating the degree of match) that match between the current value and the recommended value calculated by the parameter comparison unit 17 is displayed. "96 / 100" indicates that 96 out of 100 items of the operation parameter match. That is, the display unit 31 displays the first operation parameter (current value) stored corresponding to the first component (component D1), the second operation parameter (recommended value) of the first component estimated by the parameter estimation unit 14, and the comparison result (index indicating the degree of match) by the parameter comparison unit 17.

[0060] When the update button 50 is operated, it is set to replace the second operation parameter (estimated operation parameter 26) selected on the operation parameter update determination screen 45 with the first operation parameter currently in use, and the display transitions (returns) to the list display screen 40 (FIG. 5). When the cancel button 51 is operated, it is set not to update the operation parameter, and the display transitions (returns) to the list display screen 40.

[0061] When the display transitions to the list display screen 40, "completed" is displayed in the determination display column 41a of component D1. When the update button 43 is operated, component data 33 is created (updated) according to the conditions set on the operation parameter update determination screen 45 for component D1. That is, the parameter update unit 19 replaces and updates the second operation parameter with the first operation parameter based on the comparison result between the first operation parameter (current value) and the second operation parameter (recommended value) by the parameter comparison unit 17.

[0062] Next, referring to FIG. 7, another example of the operation parameter update determination screen 53 will be described. The operation parameter update determination screen 53 shown in FIG. 7 is different from the operation parameter update determination screen 45 shown in FIG. 6 in that the improvement rate by item is displayed in the improvement rate display column 47g of the operation parameter display frame 47 corresponding to the item display column 47a in which it is determined by the parameter comparison unit 17 that the current value and the recommended value do not match. The administrator can select the item of the recommended value to be replaced and updated while referring to the displayed improvement rate by item.

[0063] Next, referring to FIG. 8, another example of the operation parameter update determination screen 54 will be described. Hereinafter, the same parts as those in the operation parameter update determination screen 45 shown in FIG. 6 are denoted by the same reference numerals, and detailed description thereof will be omitted, and the description will be centered on the different parts.

[0064] In FIG. 8, the operation parameter update determination screen 54 displays a component name display column 46, an operation parameter display frame 47, an update button 50, a cancel button 51, a first index display column 55, and a second index display column 56. In the operation parameter display frame 47, in addition to the item display column 47a and the recommended value display column 47c, an actual value 1 display column 47h, an actual value 2 display column 47i, and a production time display column 47j are displayed.

[0065] In the actual value 1 display column 47h and the actual value 2 display column 47i, the operation parameters (first operation parameters) of the parts that are similar to or match the part information 34 of the part D1 extracted by the extraction unit 16 stored in the extracted operation parameter 29 are displayed. That is, the display unit 31 displays the first operation parameter extracted from among the first operation parameters of a plurality of parts stored in the part library 22 by the extraction unit 16. In this example, two parts are extracted as parts similar to the part D1, and the first operation parameters are respectively displayed in the actual value 1 display column 47h and the actual value 2 display column 47i.

[0066] In FIG. 8, in the production time display column 47j, the production times of the component mounting operations of the components corresponding to the recommended value display column 47c, the actual value 1 display column 47h, and the actual value 2 display column 47i stored in the production time information 27 are displayed. That is, the production times of the actual value 1 display column 47h and the actual value 2 display column 47i are the first production times at the first operation parameter (actual value) calculated by the calculation unit 15. Further, the production time of the recommended value display column 47c is the second production time at the second operation parameter (recommended value) calculated by the calculation unit 15.

[0067] In the operation parameter display frame 47, the items of the operation parameter 35 determined by the parameter comparison unit 17 not to match between the recommended value and the actual values (actual 1, actual 2) are displayed separately from the matching items. In this example, the columns of "mounting speed", "automatic teach of suction position", and "transmission lamp offset" are enclosed by broken lines H1 to H3 for distinction. In the first index display column 55, the number of items (index indicating the degree of match) that match between the recommended value calculated by the parameter comparison unit 17 and the actual 1 (actual value) is displayed. In the second index display column 56, the number of items (index indicating the degree of match) that match between the recommended value calculated by the parameter comparison unit 17 and the actual 2 (actual value) is displayed.

[0068] In FIG. 8, when the update button 50 is operated, it is set to replace all of the second operation parameters (estimated operation parameters 26) with the currently used first operation parameters, and the display screen 40 (FIG. 5) is transitioned (returned).

[0069] Next, with reference to FIGS. 9 and 10, an example of an improvement proposal during production executed while producing a mounting substrate on the component mounting line 4 will be described. The improvement proposal during production is executed for the components mounted on the mounting substrate during production (hereinafter referred to as "mounted components"). That is, the parameter estimation unit 14 estimates the estimated operation parameter 26 (second operation parameter) of the mounted component based on the learning model 25 and the component information 34 of the mounted component.

[0070] Next, the calculation unit 15 calculates the first production time based on the operation parameters 35 (first operation parameters) of the mounting components used in the component mounting apparatuses M4 and M5, and the second production time based on the estimated operation parameters 26, and calculates an improvement rate (production improvement value). That is, the first operation parameters are the operation parameters 35 used in the component mounting apparatuses M4 and M5.

[0071] The calculation unit 15 calculates the improvement rate under two conditions: a condition (no arrangement change) where the component arrangement and nozzle arrangement are not changed from the production state, and a condition (with arrangement change) where the component arrangement and nozzle arrangement are optimized to shorten the second production time. In the optimization of the component arrangement, the position of the feeder that supplies the components is changed. In the optimization of the nozzle arrangement, the position of the nozzles in the mounting head and the types of nozzles to be mounted are changed. Note that the calculation unit 15 may calculate an improvement value of the error rate as the production improvement value. In that case, as the mounting components for which the estimated operation parameters 26 are calculated, components whose production error rate (or the number of work errors) exceeds a predetermined value are selected.

[0072] Here, with reference to FIG. 9, an example of the improvement rate calculated during production will be described. The production improvement list shown in FIG. 9 includes operation parameters (during production) 58, operation parameters (recommended values) 59, and an improvement rate 60 for each component name 57. The operation parameters (during production) 58 are the operation parameters 35 (first operation parameters) of the mounting components used in the component mounting apparatuses M4 and M5. In this example, the mounting speed 58a and the suction speed 58b are displayed. The operation parameters (recommended values) 59 are the estimated operation parameters 26 (second operation parameters) estimated based on the learning model 25. In this example, the mounting speed 59a and the suction speed 59b are displayed.

[0073] The improvement rate 60 is the improvement rate of the production time calculated by the calculation unit 15, and includes the calculation results under the condition 60a without layout change and the condition 60b with layout change. In the example of FIG. 9, by changing the mounting speed 59a and the suction speed 59b among the operation parameters of the components D22 and D25 among the mounted components, it is predicted that the production time will be shortened (the improvement rate is a positive value) respectively.

[0074] FIG. 10 is an improvement proposal screen 61 displayed by the display processing unit 18 on the display unit 31 based on the production improvement list shown in FIG. 9. The display processing unit 18 displays the improvement proposal screen 61 based on the information of the mounted components extracted by the parameter comparison unit 17 assuming that the operation parameter (during production) 58 (the first operation parameter) and the operation parameter (recommended value) 59 (the second operation parameter) do not match. On the improvement proposal screen 61, a comment display frame 62, an improvement proposal display frame 63, a continue production after change button 64, and a skip button 65 are displayed. In the comment display frame 62, it is described in text that the improvement of the production time is predicted, the operation method when changing the operation parameter, and the operation method when not changing.

[0075] In the improvement proposal display frame 63, a change proposal content display column 63a, a no layout change selection column 63b, and a layout change selection column 63c are displayed. In this example, three change proposals are displayed in the change proposal content display column 63a. That is, "change of the mounting speed and suction speed of component D22", "change of the mounting speed and suction speed of component D25", and "change of both component D22 and component D25" are proposed. In the no layout change selection column 63b and the layout change selection column 63c, radio buttons for selecting changes and the predicted improvement rate are displayed.

[0076] In FIG. 10, when the change and continue production button 64 is operated with any of the radio buttons selected, the parameter update unit 19 replaces the estimated operation parameter 26 (second operation parameter) with the operation parameter 35 (first operation parameter) used in the component mounting devices M4 and M5, and updates (creates) the component data 33. In this example, since "both component D22 and component D25 are changed" under the condition of no layout change is selected, the operation parameters of component D22 and component D25 are updated. When the condition of layout change is selected, an instruction for the operator to change the component layout or nozzle layout of the component mounting devices M4 and M5 is given. When the skip button 65 is operated, the production of the mounting substrate is continued without changing the operation parameters.

[0077] Next, a component data management method (component data management program) for managing component data 33 in which the operation parameter 35 is associated with the component information 34 of the component will be described with reference to FIGS. 5 to 8 along the flow of FIG. 11. Here, among the component data management methods, a method of updating the operation parameter 35 of a component with proven performance to a recommended value expected to improve the productivity and mounting quality of the component mounting operation will be described. First, a component to be updated is set (ST11: target component setting step). For example, all components to be mounted on a newly produced mounting substrate are set as targets.

[0078] Next, the parameter estimation unit 14 estimates the second operation parameter (estimated operation parameter 26) of the target component based on the learning model 25 indicating the relationship between the operation parameter 35 and the component information 34, and the component information 34 of the target component (first component) (ST3: parameter estimation step). Next, the extraction unit 16 extracts the first operation parameter (extracted operation parameter 29) of a component whose component information 34 is similar to or matches that of the target component from among the first operation parameters of a plurality of components stored in the component library 22 (ST12: operation parameter extraction step).

[0079] In FIG. 11, next, the calculation unit 15 calculates the first production time when the target component is mounted on the substrate using the actual value (first operation parameter) of the operation parameter 35 of the target component included in the component data 33, and the second production time when the target component is mounted on the substrate using the estimated operation parameter 26 (second operation parameter) (ST13: production time calculation step). Next, the calculation unit 15 calculates a production improvement value (improvement rate) expected when the operation parameter 35 is updated from the actual value to the recommended value based on the first production time and the second production time (ST14: production improvement value calculation step).

[0080] Note that the order of the parameter estimation step (ST3) and the operation parameter extraction step (ST12) may be appropriately interchanged, or they may be executed in parallel and simultaneously. Also, the operation parameter extraction step (ST12), the production time calculation step (ST13), and the production improvement value calculation step (ST14) may be skipped when the information created on the operation parameter update determination screens 45, 53, 54 (FIGS. 6 to 8) is not displayed. For example, in the case of the operation parameter update determination screen 45 shown in FIG. 6, the operation parameter extraction step (ST12) for creating the actual value (extracted operation parameter 29) of the operation parameter may be skipped.

[0081] In FIG. 11, next, the display processing unit 18 causes the display unit 31 to display a list display screen 40 (FIG. 5) that lists and displays the target components in descending order of the production improvement value (improvement rate) (ST15: list display step). When a component for which the update determination has not been made (the determination display column 41a is blank) is selected on the list display screen 40 and the detailed display button 42 is operated, that is, when the determination has not been completed (No in ST16), the display processing unit 18 causes the display unit 31 to display the operation parameter update determination screens 45, 53, 54 of the selected component (ST17: detailed display step).

[0082] On the operation parameter update determination screens 45, 53, and 54, the first operation parameter (current value) stored corresponding to the selected component and the second operation parameter (recommended value) estimated in the parameter estimation step (ST3) are displayed so as to be comparable. That is, the detailed display step (ST17) is a parameter comparison step for comparing the first operation parameter and the second operation parameter.

[0083] On the operation parameter update determination screens 45 and 53, when an operation parameter to be updated is selected by a check button or the like displayed in the update setting column 47d and the update button 50 is operated (ST18: determination step), the process returns to the list display step (ST15) and the list display screen 40 is displayed. Also, on the operation parameter update determination screen 54, when the update button 50 is operated (ST18), all are selected as operation parameters to be updated, and the process returns to the list display step (ST15). Further, on the operation parameter update determination screens 45, 53, and 54, when the cancel button 51 is operated (ST18), it is set that the operation parameters are not updated, and the process returns to the list display step (ST15).

[0084] In FIG. 11, when it is determined that the operation parameters are to be updated for the target components listed on the list display screen 40 (ST17 to ST18) and the update button 43 is operated, that is, when the determination is completed (Yes in ST16), the parameter update unit 19 replaces the first operation parameter (current value) with the second operation parameter (recommended value) based on the comparison result and updates (creates) the component data 33 (ST19: parameter update step). Thereby, the administrator can appropriately set the operation parameters 35.

[0085] The component data 33 including the first operation parameter (estimated operation parameter 26) updated by the above-described component data management method is then transmitted to the component mounting apparatuses M4 and M5 on the component mounting line 4 and used for the production of the mounting substrate. Further, the performance information 23 of the component mounting operation using the updated component data 33 is acquired by the management computer 3 and then used when generating the learning model 25. That is, the learning unit 13 generates the learning model 25 based on the learning information 24 obtained by adding the updated first operation parameter included in the component data 33 and the information (performance information 23) regarding the first operation parameter. Thereby, the reliability of the second operation parameter (estimated operation parameter 26) estimated based on the learning model 25 can be improved.

[0086] Next, another embodiment of a component data management method (component data management program) for managing the component data 33 will be described with reference to FIG. 10 along the flow of FIG. 12. Here, among the component data management methods, a method of updating the operation parameter 35 of the mounting component to a recommended value expected to improve the productivity and mounting quality of the component mounting operation during the production of the mounting substrate on the component mounting line 4 will be described. Hereinafter, the same steps as those of the component data management method in FIG. 11 are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0087] In FIG. 12, the production of the mounting substrate is started on the component mounting line 4 (ST21), and the parameter estimation step (ST3), the production time calculation step (ST13), and the production improvement value calculation step (ST14) are executed at a predetermined timing during the production of the mounting substrate (No in ST22). The predetermined timing is, for example, a regular interval (such as every 10 minutes) or a case where the actual production time of the mounting substrate is later than the prediction (such as a 10% delay). Next, the parameter comparison unit 17 compares the first operation parameter used in the component mounting apparatuses M4 and M5 stored corresponding to the mounting component with the second operation parameter estimated in the parameter estimation step (ST3), and extracts information on the mounting component whose operation parameters do not match (ST23: parameter comparison step).

[0088] Next, the display processing unit 18 causes the display unit 31 to display an improvement proposal screen 61 (FIG. 10) based on the extracted information (comparison result) (ST24: improvement proposal display step). When any of the "change selection" radio buttons is selected on the improvement proposal screen 61 and the continue production after change button 64 is operated (Yes in ST25), the parameter update unit 19 replaces the estimated operation parameter 26 (second operation parameter) with the operation parameter 35 (first operation parameter) used in the component mounting devices M4 and M5 based on the comparison result and updates (creates) the component data 33 (ST26: parameter update step). That is, the operation parameter is updated to the recommended value and returns to (ST22). Thereby, the operation parameter can be set appropriately.

[0089] In FIG. 12, when the skip button 65 is operated on the improvement proposal screen 61 (No in ST25), it returns to (ST22) without changing the operation parameter. When the mounting substrate is being produced (No in ST22), the second parameter estimation step (ST3) to the improvement proposal display step (ST24) are executed. In the second parameter estimation step (ST3), the learning model 25 generated by the learning unit 13 may be used based on the learning information 24 obtained by adding the first operation parameter updated in the first time and the information (performance information 23) regarding the first operation parameter. When the production of the mounting substrate is completed (Yes in ST22), the component data management method (component data management program) ends.

[0090] As described above, the management computer 3 of the present embodiment includes a learning model 25 that shows the relationship between the operation parameters 35 and the component information 34, and based on the component information 34 of the first component, a parameter estimation unit 14 that estimates the operation parameters (estimated operation parameters 26) of the first component, a first operation parameter (current value) stored corresponding to the first component, and a parameter comparison unit 17 that compares the second operation parameter (recommended value) of the first component estimated by the parameter estimation unit 14, and a parameter update unit 19 that replaces and updates the second operation parameter with the first operation parameter based on the comparison result. It is a component data management device that manages the component data 33. Thereby, the operation parameters can be set appropriately.

[0091] As described above, the present invention has been described based on the present embodiment. It is understood by those skilled in the art that modifications to these embodiments and examples are also within the scope of the present invention. In the operation parameter update determination screen 45 described with reference to FIG. 6, the current value (current value display column 47b) and the recommended value (recommended value display column 47c) are displayed, but the actual result value may be used instead of the recommended value. As a method of displaying the actual result value, as described in the present embodiment, there is a method of displaying the first operation parameter extracted from the first operation parameters of a plurality of components stored in the component library 22 by the extraction unit 16 on the display unit 31.

[0092] The following are examples of cases where the actual result value is displayed instead of the recommended value. When the second operation parameter cannot be estimated by the parameter estimation unit 14. When the improvement effect cannot be expected from the production improvement value expected when the operation parameter 35 is updated from the actual result value to the second operation parameter estimated by the parameter estimation unit 14 (for example, the improvement rate is zero or a negative value). When the production improvement value expected when the actual result value is updated to the first operation parameter extracted from the first operation parameters of a plurality of components stored in the component library 22 by the extraction unit 16 is higher than the production improvement value expected when the operation parameter 35 is updated from the actual result value to the second operation parameter estimated by the parameter estimation unit 14.

[0093] Note that the "first component" used in the above description is a term used for the purpose of explanation and is not limited thereto. For example, it may be expressed using other terms such as "a component", "component A", or "a specific component".
