Description

The present invention relates to a component data management method, a component data management device, a component data management program, and a component data management system for managing component data used by a component mounting device that mounts components on a board.

The component mounting device that mounts components on a board controls the component mounting operation based on a large number of operating parameters, including operating conditions related to mounting the components on the board, suction of the components by the nozzle, photographing the components, etc. Appropriate values are set for each component as the operating parameters, which are part data linked to the component information, including information such as the shape of the component. Some of the operating parameters may be changed if a mounting error occurs during the component mounting operation. Patent Document 1 discloses a system that records the change history of the component data and mounting error information, displays the progress of the mounting error on the display, and further displays past component data when a date and time is specified, restoring the component data to the correct state.

However, in conventional technologies including Patent Document 1, component data for the same component is changed by different workers each time a mounting error occurs, which reduces the frequency of mounting errors but also creates component data that reduces productivity, or creates multiple derived component data for the same component. There is room for further improvement in restoring component data to an appropriate state from such a state.

The present invention therefore aims to provide a parts data management method, a parts data management device, a parts data management program, and a parts data management system that can properly restore changed parts data to a previous state.

One embodiment of the present invention will be described in detail below with reference to the drawings. The configurations, shapes, etc. described below are examples for explanatory purposes and can be modified as appropriate depending on the specifications of the production system, component mounting line (production line), component mounting device, and component data management device. In the following, corresponding elements in all drawings will be given the same reference numerals, and duplicate explanations will be omitted.

First, the configuration of production system 1 will be described with reference to Figure 1. Production system 1 is comprised of a customer's factory F1 and a support center S that is established at a location away from factory F1 and supports the customer's production activities. Factory F1 is equipped with a component mounting line that produces mounted circuit boards as a production line that produces finished products.

In FIG. 1, a factory F1 is equipped with one component mounting line L1, which is made up of connected production equipment such as a printing device M1 and multiple component mounting devices M2 and M3. The component mounting line L1 has the function of producing mounted boards by mounting components on the boards in sequence using the printing device M1 and the component mounting devices M2 and M3. Note that the component mounting line L1 installed in the factory F1 does not need to be one, but may be two or more. Furthermore, the component mounting devices M2 and M3 that make up the component mounting line L1 do not need to be two, but may be one, or three or more.

Each production device in the factory F1 is connected to an on-site communication network 2 such as a LAN (Local Area Network), and is connected to a production management device 3 via an internal communication unit 4. The production management device 3 has a function of creating data and parameters necessary for the operation of the production devices equipped on the component mounting line L1, and transmitting them to each production device. In addition, data such as the operating status and work history of each production device is transmitted from each production device to the production management device 3. In addition, the production management device 3 has a function of creating component data, production data, etc. used by the production devices on the component mounting line L1. In addition to the production management device 3, the factory F1 may be configured to include a line management device for managing the production of mounted boards for each component mounting line L1.

In FIG. 1, a parts data management device 7 is installed in the support center S. The production management device 3 in the factory F1 has an external communication unit 5. The parts data management device 7 in the support center S also has an external communication unit 8. The external communication units 5 and 8 are connected to an off-site communication network 6 such as the Internet or a mobile communication line. With this configuration, the production management device 3 and the parts data management device 7 can exchange information via the off-site communication network 6. The parts data management device 7 acquires performance information and parts data of the production device from the production management device 3 in the factory F1 and stores them in a database. The parts data management device 7 also has a function of extracting information from the database and transmitting (outputting) it in response to a request from the production management device 3.

The production management device 3 and the parts data management device 7 are not limited to a configuration in which they directly exchange information via the off-site communication network 6, and may exchange information via the cloud. That is, information sent from each device may be stored in the cloud, and information may be sent from the cloud to each device upon request. Information may also be sent and received using communication tools that utilize email or data communication lines.

Next, referring to FIG. 1, the component mounting line L1 will be described. The printing device M1 is a production device that has the function of performing solder printing work, which involves screen-printing cream solder for component joining onto a board. The component mounting devices M2 and M3 are production devices that have the function of performing component mounting work, which involves attaching components to the board after solder printing.

Based on the operating parameters included in the component data set for each component to be mounted on the board, component mounting devices M2 and M3 use a nozzle on the mounting head to vacuum pick up components supplied by the feeder, capture an image of the component held by the nozzle with a component recognition camera, and mount the component at the mounting position on the board at a specified mounting angle. Component mounting devices M2 and M3 are equipped with multiple sensors to monitor operational mistakes and operational errors during component mounting work, such as the suction operation in which the nozzle picks up the component and the component recognition operation in which the component recognition camera captures and recognizes the picked component.

Next, referring to FIG. 2, the configuration of the production system 1 (component data management system) equipped with the production management device 3 and the component data management device 7 will be described. Here, the configuration will be mainly described regarding the component data restoration function that returns the component data that has been changed and is used by the component mounting devices M2 and M3 to the previous appropriate state after the multiple functions equipped with the production management device 3 and the component data management device 7.

An internal communication unit 4, an external communication unit 5, an input unit 9, and a display unit 10 are connected to a production management device 3 installed in factory F1. The production management device 3 includes a production management memory unit 11, a data collection unit 15, a data creation unit 16, a data restoration unit 17, a counting unit 18, a judgment unit 19, and a control unit (not shown). The production management memory unit 11 is a storage device such as a semiconductor memory or a hard disk drive, and stores a production library 12, a parts library 13, performance data 14, etc.

The input unit 9 is an input device such as a keyboard, touch panel, or mouse, and is used for inputting operation commands and data. The display unit 10 is a display device such as a liquid crystal panel, and displays various data stored in the production management storage unit 11, as well as various information such as an operation screen and an input screen for operation by the input unit 9. The control unit is, for example, a CPU (Central Processing Unit), and controls the entire production management device 3.

In FIG. 2, production library 12 stores production data used in the production of mounted boards by component mounting devices M2 and M3 for each production model name of the mounted board. The production data includes component names that identify the components to be mounted on the board, component codes that associate the components with component data in component library 13, the mounting position of the components on the board, the mounting angle, component arrangements that indicate the positions of feeders that supply the components in component mounting devices M2 and M3, and nozzle arrangements that indicate the positions of nozzles that pick up the components in the mounting head. Component library 13 stores multiple component data in which operation parameters are linked to component information. The component data is associated with the production data in production library 12 by component data codes.

Now, referring to FIG. 3, an example of part data 20 contained in the part library 13 will be described. The part data 20 is associated with the production data by "part n" (part data code) contained in the part data 20 and the part data code of the production data contained in the production library 12. In this example, the part library 13 stores part data 20 for multiple types of parts having part data codes of n=1, 2, 3, .... The part data 20 specifies part information 21 and operation parameters 22 as major classification items.

Part information 21 is information that indicates attributes unique to the part. Here, "Name" 21a, "Shape" 21b, "Size" 21c, and "Part parameters" 21d are exemplified as medium classification items. "Name" 21a is product number information for identifying the part, and the "product number" assigned by the part manufacturer or the company itself for management purposes is defined as a minor classification item. "Shape" 21b is information about the shape of the part, and the minor classification items include "shape" that indicates the external shape of the part by a shape category such as rectangular or cylindrical, a drawing showing the shape of the part, and information that specifies image information.

In "Size" 21c, subcategories such as "External Dimensions" indicating the size of the part, and "Electrode Position" indicating the number and position (spacing) of connection electrodes (leads) formed on the part are specified. "Part Parameters" 21d is attribute information of the part, and subcategories such as "Part Type" indicating the type of part, "Polarity" indicating whether the external shape of the part has a directional property, "Polarity Mark" indicating the shape of the mark attached to the part if polarity is present, and "Mark Position" indicating the position of the mark if polarity is present are specified. In this way, part information 21 includes at least one of the following items: part dimensions (size 21c), part number information (product name 21a), number of leads, lead spacing information (size 21c), and image information (shape 21b).

In FIG. 3, the operating parameters 22 are control parameters (operating conditions) used to control the component mounting devices M2 and M3 arranged on the component mounting line L1 when performing component mounting work on the components specified in the component data 20. Here, examples of intermediate classification items include "nozzle setting" 22a, "speed parameter" 22b, "recognition" 22c, "pickup" 22d, and "mounting" 22e.

"Nozzle setting" 22a is data related to the suction nozzle used to pick up and hold the component, and "nozzle" is specified as a minor category to specify the type of suction nozzle that can be selected. In addition to type, "nozzle" data may also include opening diameter, identifier, etc. "Speed parameter" 22b is a control parameter related to the movement speed of the suction nozzle in the work operation of picking up the component with the suction nozzle and mounting it on a board. These control parameters include, as minor categories, the "pickup speed" and "pickup holding time" when picking up and holding the component, and the "mounting speed" and "mounting holding time" when mounting the held component on a board.

In FIG. 3, "recognition" 22c is a parameter related to the execution of a recognition process in which a component recognition camera captures and recognizes a component picked up by a suction nozzle from a component supply unit. These parameters include, as subcategory items, "camera type" that specifies the type of camera used for capturing the image, "lighting mode" that indicates the lighting mode used when capturing the image, and "recognition speed" when recognizing the image obtained by capturing the image.

"Suction" 22d is a control parameter related to the suction operation when a component is taken out of the component supply unit by the suction nozzle. These control parameters include sub-categories such as "suction position X" and "suction position Y" which indicate the suction position offset when the suction nozzle lands on the component. "Placement" 22e is a control parameter related to the placement operation in which the mounting head which holds the component by suction with the suction nozzle is moved to the board, and the suction nozzle is raised and lowered to place the component on the board. These control parameters include sub-categories such as "placement load", which is the load that presses the component against the board when the suction nozzle is lowered to place the component on the board.

In FIG. 3, even if the "product name" 21a is the same, i.e., the component information 21 is the same, the operating parameters 22 may be changed due to changes in the type of component mounting device M2, M3 mounted on the board, the material of the board, the electrodes of the board, etc., or to improve mounting quality or mounting error rate. When the operating parameters 22 of the component are changed, component data 20 is created (updated) linked to the changed operating parameters 22 without changing the component information 21. At this time, a new code is assigned to "component n" (component data code) in the component data 20 to distinguish it from the operating parameters 22 before modification.

In this way, component data 20 is linked to component information 21 indicating the unique attributes of the component, and operation parameters 22 that are the operating conditions for component mounting devices M2 and M3 to mount the component on a board. The component data 20 in component library 13 is transmitted to component mounting devices M2 and M3 on component mounting line L1 together with the production data in production library 12, and is used in the production of mounted boards by component mounting devices M2 and M3.

In FIG. 2, the data collection unit 15 collects component mounting work results from the production devices (printing device M1, component mounting devices M2, M3) on component mounting line L1 installed in factory F1. The component mounting work results include information such as the production start date and time and production end date and time (the period during which components were mounted), the number of sheets produced, the number of component pickups, the number of component mountings, the number of operational errors, the error rate (frequency), and the number of operational errors and their contents.

When an operator creates or modifies component data 20, the data creation unit 16 displays a component data creation screen on the display unit 10 to assist the operator in creating the component data. The creation and modification of component data 20 is performed during preparation work before mounting a new component on a board, or during improvement work when a mounting error occurs.

Now, referring to FIG. 4, an example of a part data creation screen 50 displayed on the display unit 10 by the data creation unit 16 will be described. The part data creation screen 50 has a part information setting area 51 and an operation parameter setting area 52. The part information setting area 51 has a part name setting frame 53, a part shape setting frame 54, a size information setting frame 55, and a details display button 56. The operation parameter setting area 52 has an operation parameter setting frame 57, a cancel button 58, and a create button 59.

In the part name setting frame 53, the part name (product name 21a in part information 21) of the part for which part data 20 is to be created is input. In the part shape setting frame 54, the external shape of the part (shape 21b in part information 21) is input. In the size information setting frame 55, the external dimensions, body size, electrode position, etc. of the part (size 21c in part information 21) are input. When the details display button 56 is operated, the screen transitions to a screen (not shown) that displays details of the part information 21.

In FIG. 4, an item display field 57a, a parameter setting field 57b, and a scroll bar 57c are displayed in the operation parameter setting frame 57. By operating the scroll bar 57c, the operation parameters displayed in the operation parameter setting frame 57 are scrolled. The item display field 57a displays items corresponding to the subcategory items of the operation parameters 22 shown in FIG. 3. The operator operates the input unit 9 to input parameters into the parameter setting field 57b.

When the Cancel button 58 is operated, the creation of the part data 20 is canceled. When the Create button 59 is operated, the data creation unit 16 creates the part data 20 using the parameters set on the part data creation screen 50, and stores it in the part library 13. At that time, the data creation unit 16 assigns a new code to the "part n" (part data code) of the part data 20, links it to the date and time of creation of the part data 20, and information identifying the worker who created the part data 20, and stores it in the part library 13.

In FIG. 2, the parts data management device 7 installed in the support center S has the function of collecting and managing parts data 20 and performance data 14 used in the customer's factory F1. An external communication unit 8 and a storage device 30 are connected to the parts data management device 7. The storage device 30 is, for example, a semiconductor memory or a hard disk drive. The storage device 30 stores information such as extraction conditions 32 for the parts data 20 transmitted from the factory F1, and also includes a database 31 that stores information such as the parts data 20 and performance data 14 acquired from the factory F1. The database 31 may also include data prepared in advance by an EDA (Electronic design automation) vendor.

The part data management device 7 includes information processing devices such as an acquisition unit 40, a storage processing unit 41, a reception unit 42, an extraction unit 43, an output unit 44, and a control unit (not shown). Each information processing device may be configured with independent hardware assets, or may be configured with a common CPU and programs for each information processing. The control unit is, for example, a CPU (Central Processing Unit), and controls the entire part data management device 7. Furthermore, the part data management device 7 does not need to be configured with one computer, and may be configured with multiple devices. For example, the storage device 30 and all or part of the information processing devices may be provided in the cloud via a server.

In FIG. 2, the acquisition unit 40 acquires from the factory F1 via the external communication unit 8 the component data 20 used by the component mounting devices M2 and M3, the creation date and time of the component data 20, and performance data 14 obtained when components are mounted by the component mounting devices M2 and M3 using the component data 20. The acquisition unit 40 acquires data at a predetermined time, for example, once a day, and acquires information updated since the previous data acquisition. The storage processing unit 41 executes a storage process that links the acquired component data 20, the creation date and time of the component data 20, and the performance data 14, and stores them in the database 31. In this way, the component data 20 and performance data 14 used in the factory F1 are periodically saved (backed up) in the database 31.

When an operator restores component data 20 to a past state, the data restoration unit 17 of the production management device 3 displays a component data restoration condition setting screen and a component data restoration setting screen on the display unit 10 to assist the operator in the restoration work. The restoration work is performed when, during the production of mounting boards, productivity drops below past performance levels or the error rate increases.

Now, referring to FIG. 5, an example of the part data restoration condition setting screen 60 displayed on the display unit 10 by the data restoration unit 17 will be described. The part data restoration condition setting screen 60 is used to set the part name and extraction conditions of the part data 20 of the part to be restored (hereinafter referred to as the "first part"). The part data restoration condition setting screen 60 has a part information display area 61 and an extraction condition setting area 62. The part information display area 61 has a part name setting frame 63, a part shape display frame 64, a size information display frame 65, and a details display button 66. The extraction condition setting area 62 has an extraction condition setting frame 67, a cancel button 68, and an extract button 69.

In the part name setting frame 63, the part name of the first part (product name 21a in part information 21) for restoring the part data 20 is entered. In the part shape display frame 64, the external shape of the first part (shape 21b in part information 21) entered in the part name setting frame 63 is displayed. And in the size information display frame 65, the external dimensions, body size, electrode position, etc. (size 21c in part information 21) of the first part entered in the part name setting frame 63 are displayed. When the details display button 66 is operated, the screen transitions to a screen (not shown) that displays details of the part information 21 of the first part.

In FIG. 5, the extraction condition setting frame 67 sets the extraction conditions for the past component data 20 of the first component to be restored. In this example, the items that can be set as extraction conditions are the usage period (extraction period) of the component data 20, productivity (number of components mounted per unit time), error rate (number of mounting errors per unit number of components mounted), and number of results (total number of components mounted in the extraction period). The worker operates the radio button 67a to set each item as "used" or "not used." The worker also operates the increase/decrease button 67b to set the range of each item. In FIG. 5, the extraction conditions that are set for the restoration target are the first component with the component name "D11," the usage period as "from January 1, 2021 to January 10, 2021," and the productivity as "10,000 CHP or more."

When the cancel button 68 is operated, the setting of the extraction conditions for the part data 20 is canceled. When the extract button 69 is operated, the data restoration unit 17 transmits the extraction conditions set on the part data restoration condition setting screen 60 to the part data management device 7 via the external communication unit 5.

In FIG. 2, the reception unit 42 of the part data management device 7 receives extraction conditions sent from the factory F1 to send back information required to restore the part data 20 to a past state. That is, the reception unit 42 receives the part information 21 of the first part to be restored and extraction conditions 32 including at least one item of the creation date and time of the part data 20 and the performance data 14 (period of use, productivity, error rate, number of performances). The reception unit 42 stores the received extraction conditions 32 in the storage device 30. The extraction unit 43 extracts from the database 31 part data 20 that matches the part information stored in the database 31 and satisfies the extraction conditions 32, based on the part information 21 of the first part received by the reception unit 42 and the extraction conditions 32.

The output unit 44 outputs (transmits) the part data 20 and the like extracted by the extraction unit 43 to the requesting production management device 3 via the external communication unit 8. The output unit 44 may output only the operation parameters 22 of the extracted part data 20. The output unit 44 may also output the creation date and time of the part data 20 and performance data 14 in addition to the part data 20 (operation parameters 22). That is, the output unit 44 outputs the creation date and time of the extracted part data 20 and at least one item of the performance data 14 in addition to the operation parameters 22 of the extracted part data 20.

In FIG. 2, the data restoration unit 17 of the production management device 3 displays on the display unit 10 a part data restoration setting screen that supports the task of restoring the part data 20 based on information transmitted from the output unit 44 of the part data management device 7. That is, when the extraction button 69 is operated on the part data restoration condition setting screen 60 to transmit the extraction conditions 32 to the part data management device 7, the data restoration unit 17 subsequently displays the part data restoration setting screen on the display unit 10.

Now, referring to FIG. 6, an example of the part data restoration setting screen 70 displayed on the display unit 10 by the data restoration unit 17 will be described. The part data restoration setting screen 70 has a part name display field 71, an operation parameter display frame 72, a decision button 73, a cancel button 74, and a part information display button 75 arranged therein. The part name display field 71 displays the part name (D11) of the first part to be restored. The operation parameter display frame 72 displays an item display field 72a, a current value display field 72b, an extracted value 1 display field 72c, an extracted value 2 display field 72d, a selection button field 72e, a creation date and time display field 72f, a performance display field 72g, and a scroll bar 72h.

When the scroll bar 72h is operated, the operating parameters displayed in the operating parameter display frame 72 are scrolled. The item display field 72a displays items corresponding to the subcategory items of the operating parameters 22 shown in FIG. 3. The current value display field 72b displays the operating parameters 22 of the component D11 (first component) currently used in the component mounting devices M2 and M3. The extracted value 1 display field 72c and the extracted value 2 display field 72d display the past operating parameters 22 of the component D11 extracted from the database 31 based on the extraction conditions 32. The creation date and time display field 72f displays the creation date and time of the operating parameters (component data 20) displayed in the current value display field 72b, the extracted value 1 display field 72c, and the extracted value 2 display field 72d.

In FIG. 6, the performance display field 72g displays the performance (performance data 14) of the productivity when the operating parameters 22 (component data 20) displayed in the current value display field 72b, the extracted value 1 display field 72c, and the extracted value 2 display field 72d are used in component mounting devices M2 and M3. In this example, the "current value" is a mounting speed of "20%" and a productivity of "9000 CPH," the "extracted value 1" is a mounting speed of "80%" and a productivity of "11000 CPH," and the "extracted value 2" is a mounting speed of "100%" and a productivity of "12000 CPH."

When the radio button displayed in the selection button field 72e is operated, one of the operating parameters 22 displayed in the current value display field 72b, the extracted value 1 display field 72c, or the extracted value 2 display field 72d is selected as the part data 20 to be restored. In this example, "extracted value 2" is selected. When the part information display button 75 is operated, the screen transitions to a screen (not shown) that displays details of the part information 21 of part D11 (first part).

In FIG. 6, when the cancel button 74 is operated, the selection of the component data 20 is canceled and the screen returns to the component data restoration condition setting screen 60. When the confirm button 73 is operated, the data restoration unit 17 restores the component data 20 of the component D11 (first component) used in the component mounting devices M2 and M3 to the conditions selected in the selection button field 72e. In this example, the component data is restored to "Extracted value 2" created on "January 5, 2021, 10:50."

Specifically, the data restoration unit 17 links the part information 21 of the first part to the operation parameter 22 (extracted value 2) selected from the operation parameters 22 (extracted value 1, extracted value 2) of the part data 20 output from the part data management device 7 (database 31), creates (restores) it as part data 20 of the first part, and stores it in the part library 13. Note that if "current value" is selected on the part data restoration setting screen 70, the part data 20 of the first part is not changed. In this way, even if old part libraries 13 and performance data 14 stored in the production management storage unit 11 are periodically deleted, the changed part data 20 can be appropriately restored to a past state based on the data saved in the database 31.

In FIG. 2, the aggregation unit 18 of the production management device 3 aggregates performance data 14 for each part (first part) based on performance information collected by the data collection unit 15. The judgment unit 19 judges whether the performance data 14 aggregated by the aggregation unit 18 includes any part that exceeds a predetermined range. For example, the judgment unit 19 judges that the predetermined range has been exceeded when the productivity of the performance data 14 falls below the lower limit of 9000 CPH or the error rate exceeds the upper limit of 600 PPM.

When the data restoration unit 17 automatically restores the part data 20 from the judgment result of the judgment unit 19, the data restoration unit 17 creates extraction conditions 32 for a part (first part) that exceeds a predetermined range and transmits them to the part data management device 7. For example, the data restoration unit 17 automatically creates extraction conditions 32 based on predetermined conditions, such as a usage period of the past 30 days, a productivity of 10,000 CPH or more, and an error rate of 500 PPM or less. Then, the data restoration unit 17 restores the part data 20 that matches the predetermined conditions from the extraction results extracted by the extraction unit 43 of the part data management device 7 and transmitted by the output unit 44 as part data 20 for the first part, and stores the restored data in the part library 13. For example, the predetermined conditions are conditions for selecting the part data 20 with the highest productivity from among the extracted part data 20.

In this way, the aggregation unit 18 aggregates the performance data 14 of the first component while the component mounting devices M2 and M3 are mounting the components, the judgment unit 19 judges whether the aggregated performance data 14 of the first component exceeds a predetermined range, and when it is judged that the predetermined range is exceeded, the data restoration unit 17 creates extraction conditions 32 and transmits them to the component data management device 7. The reception unit 42 accepts the component information 21 of the first component that is judged to have exceeded the predetermined range, the extraction unit 43 extracts the component data 20 that satisfies the extraction conditions 32 from the database 31, and the output unit 44 outputs the operation parameters 22 of the extracted component data 20. Then, the data restoration unit 17 selects one of the operation parameters 22 of the output component data 20, links the component information 21 of the first component to the operation parameter 22, and restores it as the component data 20 of the first component.

Next, a component data management method (data management program) for managing component data 20 will be described with reference to the flow in Figure 7. Here, an example of a flow for restoring component data 20 when performance data 14 exceeds a predetermined range will be described. First, the data collection unit 15 of the production management device 3 of factory F1 collects performance data of component mounting work from component mounting devices M2, M3 of component mounting line L1 (production line) installed in factory F1 (ST1: data collection process). The collected information is stored in the production management memory unit 11 as performance data 14.

Then, the acquisition unit 40 of the component data management device 7 of the support center S acquires from the production management device 3 of the factory F1 the component data 20 used by the component mounting devices M2 and M3, the creation date and time of the component data 20, and the performance data 14 obtained when the component is mounted by the component mounting devices M2 and M3 using the component data 20 (ST2: acquisition process). Next, the storage processing unit 41 links the acquired component data 20, the creation date and time, and the performance data 14 and stores them in the database 31 (ST3: storage process). For example, the acquisition process (ST2) and the storage process (ST3) are performed once a day at a specified time, and the component data 20 and performance data 14 used in the factory F1 are periodically saved (backed up).

In FIG. 7, the counting unit 18 of the production management device 3 counts the performance data 14 collected in the data collection process (ST1) by part name (ST4: counting process). Next, the judgment unit 19 judges whether or not there is a part (part name) that exceeds a predetermined range in the performance data 14 for each part name collected in the counting process (ST4) (ST5: judgment process). If there is no part that exceeds the predetermined range (No in ST5), the counting process (ST4) and the judgment process (ST5) are executed repeatedly. If there is a part that exceeds the predetermined range (Yes in ST5), the judgment unit 19 sets that part as the first part to be restored.

In this way, while the component mounting devices M2 and M3 are mounting the components, the performance data 14 of the first component is tallied (ST4), and it is determined whether the tallied performance data 14 of the first component exceeds a predetermined range (ST5). The judgment step (ST5) may be automatically performed by the judgment unit 19, or an operator may refer to the performance data 14 for each component name tallied in the tallying step (ST4) and determine whether or not the component data 20 needs to be restored.

When it is determined that the performance data 14 of the first part exceeds the predetermined range (Yes in ST5), extraction conditions 32 including the part information 21 of the first part, the usage period (creation date and time) of the part data 20, and the performance data 14 are created by the worker or automatically (ST6: extraction condition creation process). When created by the worker, the data restoration unit 17 causes the display unit 10 to display the part data restoration condition setting screen 60, and the worker operates the part data restoration condition setting screen 60 to create the extraction conditions 32. When extraction conditions 32 are created automatically, the data restoration unit 17 creates the extraction conditions 32 based on predetermined conditions.

In FIG. 7, when the extraction conditions 32 are created, the data restoration unit 17 transmits the extraction conditions 32 to the part data management device 7 via the external communication unit 5. Next, the reception unit 42 of the part data management device 7 receives the extraction conditions 32 that include at least the part information 21 of the first part to be restored (ST7: reception process). In this way, when it is determined in the judgment process (ST5) that the predetermined range has been exceeded (Yes), the part information 21 of the first part determined to have been exceeded is received in the reception process (ST7).

Then, the extraction unit 43 extracts from the database 31 the part data 20 in which the received part information 21 of the first part matches the stored part information 21 and satisfies the extraction condition 32 based on the extraction condition 32 (ST8: extraction process). The output unit 44 then outputs (transmits) the operation parameters 22, creation date and time, and performance data 14 of the extracted part data 20 to the requesting production management device 3 via the external communication unit 8 (ST9: output process).

In FIG. 7, when the data restoration unit 17 then acquires (receives) the output information, one of the multiple output (extracted) part data 20 (operation parameters 22) is selected by the worker or automatically (ST10: selection process). When the worker selects an operation parameter 22, the data restoration unit 17 causes the display unit 10 to display the part data restoration setting screen 70, and the worker operates the part data restoration setting screen 70 to select one operation parameter 22. When the operation parameter 22 is selected automatically, the data restoration unit 17 selects one operation parameter 22 based on predetermined conditions.

The data restoration unit 17 then links the component information 21 of the first component to the operation parameters 22 selected from the operation parameters 22 of the output component data 20, and creates the component data 20 of the first component (ST11: Creation process). That is, based on the information stored in the database 31, the component data 20 of the first component is restored to a past appropriate state. The component data 20 of the first component restored in this manner is stored in the component library 13 and used by the component mounting devices M2 and M3. In this manner, based on the data of the database 31 that is periodically backed up, the component data 20 of the first component that is not stored in the production management device 3 can be appropriately restored to a past appropriate state.

As described above, the part data management device 7 for managing the part data 20 of this embodiment includes an acquisition unit 40 that acquires at least the part data 20 used, the creation date and time of the part data 20, and performance data 14 obtained when a part is mounted using the part data 20, a storage processing unit 41 that links the acquired part data 20, the creation date and time, and the performance data 14 and stores them in the database 31, a reception unit 42 that accepts at least the part information 21 of the first part, an extraction unit 43 that extracts part data 20 whose stored part information 21 matches the received part information 21 of the first part from the database 31, and an output unit 44 that outputs at least the operation parameters 22 of the extracted part data 20. This allows the changed part data 20 to be appropriately restored to a previous state.

In the above embodiment of the production system 1 (parts data management system), the support center S (parts data management device 7) is installed outside the factory F1, but the support center S (parts data management device 7) may be installed within the factory F1.

The component data management method, component data management device, component data management program, and component data management system of the present invention have the effect of being able to properly restore changed component data to a previous state, and are useful in the field of mounting components on a board.
