The board transfer device 21 sequentially conveys the board 91 in the transfer direction, and positions the board 91 at a predetermined position in the machine. The component mounting machine 12 includes a component supply device 22. The component supply device 22 supplies components to be mounted on the substrate 91. The component supply device 22 is equipped with a feeder 222 in each of a plurality of slots 221. A tape feeder is applied to the feeder 222, for example, by feeding and moving a carrier tape containing a large number of parts so that the parts can be collected.

The parts mounting machine 12 includes a parts transfer device 23. The component transfer device 23 transfers the components supplied by the component supply device 22 to a predetermined mounting position on the substrate 91. The component transfer device 23 includes a head drive device 231, a moving table 232, and a mounting head 233. The head drive device 231 moves the moving table 232 in the horizontal direction (X direction and Y direction) by the linear motion mechanism. The mounting head 233 is detachably fixed to the moving table 232 by a clamp member (not shown), and is provided so as to be movable in the machine in the horizontal direction.

The mounting head 233 supports the plurality of holding members so as to be able to move up and down and rotatably around the rotation axis of each of the plurality of holding members. In the present embodiment, the holding member is a suction nozzle 234 that holds the component by sucking the component with the supplied negative pressure air. As the holding member, a chuck or the like that holds the component by gripping it may be adopted.

The component mounting machine 12 includes a component camera 24 and a board camera 25. The component camera 24 and the substrate camera 25 are digital image pickup devices having an image pickup element such as CMOS. The component camera 24 and the substrate camera 25 take an image based on the control signal and send out the image data acquired by the image pickup. The component camera 24 is provided on a base fixed to the installation floor, and is configured so that the component held by the suction nozzle 234 can be imaged from below. The board camera 25 is provided on the moving table 232 so as to be movable in the horizontal direction integrally with the mounting head 233. The board camera 25 is configured so that the board 91 can be imaged from above.

The component mounting machine 12 includes a control device 30. The control device 30 is mainly composed of a CPU, various memories, and a control circuit. The control device 30 acquires and stores various data such as control data D3 and component information used for controlling the mounting process from the management device 40. As shown in FIG. 3, the control data D3 indicates the type, mounting position, mounting angle, and mounting order of the parts to be mounted on the substrate 91 in the mounting process. In the above mounting process, a collecting operation of collecting the parts supplied by the parts supply device 22 by a holding member (suction nozzle 234) and mounting of the parts at a predetermined mounting position on the substrate 91 at a predetermined mounting angle are performed. A PP cycle (pick and place cycle) that repeatedly executes the operation is included.

Parts information is information unique to each type of part. In addition to the type of parts, this part information may be classified in detail by indicators such as the producer of the parts, the production lot, the production time, and the control status. However, for parts of the same type, there are many parts in common in each part information due to their functions and characteristics. The component information includes parameter data D4 and shape data D5. The parameter data D4 indicates the conditions for mounting the component on the substrate 91. In the present embodiment, the parameter data D4 may include a maximum allowable moving speed (may be an allowable acceleration) for each component, a sampling position (for example, a position in contact with the suction nozzle 234), and the like.

The shape data D5 indicates the shape of the part used for recognizing the appearance of the part. In the present embodiment, the shape data D5 includes at least one of the outer edge shape of the part, the shape of the feature portion of the part, and the dimension of the part. The "outer edge shape" of a part corresponds to the shape of the outer edge when the inside and the background of the part are separated by the outer edge of the part as a boundary. The "shape of the feature portion" of the part corresponds to the boundary shape of the feature portion on the appearance caused by the shape, pattern, color, etc. of the part. As the characteristic portion of the component, a corner portion, a bump, a terminal, a lead portion, or the like of the component may be applied.

The control device 30 includes a display device 31. The display device 31 is provided so as to be visible to the operator and displays various information. In the present embodiment, the display device 31 has a touch screen and a plurality of buttons, and receives an operation by an operator in cooperation with various input devices.

The control device 30 controls the mounting operation by the mounting head 233 so that the parts are mounted on the board 91 in a predetermined posture in the mounting process. At this time, the control device 30 controls the mounting operation based on the holding state of the parts by the suction nozzle 234 recognized by the parts camera 24 and various data. That is, the control device 30 brings the suction nozzle 234 into contact with the suction position on the component designated by the component information to collect the component. Further, the control device 30 performs image processing on the image data acquired by the image pickup of the component camera 24, and recognizes the holding state of the component based on the shape data D5.

Further, the control device 30 controls the operation of the mounting head so that the moving speed and acceleration of the parts are within the permissible range based on the parameter data D4. Further, the control device 30 lowers the suction nozzle 234 in the mounting operation based on the parameter data D4, and after the component comes into contact with the substrate 91, raises the suction nozzle 234 and supplies positive pressure air to the suction nozzle 234. And try to open the parts. Then, the control device 30 separates the suction nozzle 234 from the component and moves the mounting head 233 to mount the component at the next mounting position.

4. Configuration of Data Management System 50 In the mounting process as described above, the component information may be edited in order to collect and mount the component with higher accuracy and efficiency. Specifically, for a predetermined type of component, the shape definition and tolerance in the shape data D5 are adjusted in order to improve the recognition accuracy in image processing. Further, even if the parts are of the same type, if the producers are different, the unevenness and the position of the center of gravity of the upper surface of the parts (the suction surface by the suction nozzle 234) may be different. Data D5 is adjusted.

Such editing of component information is preferably reflected in the component mounting machine 12, for example, when the same type of component is mounted or is scheduled to be mounted in another component mounting machine 12. There are many. However, it is not always optimal for various reasons to uniformly update the editing of component information to a board-to-board working machine such as another component mounting machine 12.

For example, if the content of editing for work-related data Rd (control data D3, parts information, etc.) corresponds to a shape or state peculiar to a predetermined production lot, mounting parts of another production lot are mounted. Even if it is applied to the process, the editing effect may not be obtained. In addition, the same applies when the edited content corresponds to the individual difference of the equipment used for the mounting process, the production environment of each component mounting machine 12, and the like, which may be a factor of lowering the productivity.

Therefore, the data management system 50 of the present embodiment adopts a configuration that enables the work-related data Rd of the other machine to be appropriately reflected when the work-related data Rd is edited on the production line Ln. As a result, the data management system 50 maintains the stability of production and prevents the production efficiency from deteriorating.

In the following, the board-to-board work machine that was executing the board-to-board work using the edited original work-related data Rd, or the board-to-board work machine that is scheduled to perform the board-to-board work is referred to as the first work machine M1. do. Further, among a plurality of anti-board work machines, the anti-board work machine is different from the first work machine M1 and performs a predetermined anti-board work using the same type of data as the edited work-related data Rd. The machine is referred to as a second working machine M2.

4-1. Editorial department 51
As shown in FIG. 4, the data management system 50 includes an editorial unit 51. The editorial unit 51 accepts editing of work-related data Rd. In the present embodiment, the editorial unit 51 is provided in the first working machine M1. Some of the plurality of anti-board work machines including the component mounting machine 12 have an editing unit 51 and have a function of editing work-related data Rd used for the anti-board work of the own machine.

Here, it is assumed that the operator discovers that, for example, when an error occurs during the execution of the mounting process, the cause lies in the definition of the shape of the part in the shape data D5. In such a case, the operator causes the display device 31 to display the shape data D5 as the work-related data Rd, and adjusts the definition of the shape of the component in the shape data D5 via the input device. The editorial unit 51 accepts editing of work-related data Rd as described above.

The editorial unit 51 stores the edited work-related data Rd in the control device 30. At this time, the editorial unit 51 also stores the identification information unique to the edited work-related data Rd and the information related to the editing work. The above-mentioned unique identification information is, for example, a character string assigned a code for numbering the original identification information so that it can be identified as being derived from the original work-related data Rd. In addition, the above-mentioned related information includes the content of editing (for example, setting values before and after editing, adjustment amount, etc.) or motivation for editing (error occurrence, reduction of cycle time, improvement of mounting accuracy, etc.).

Further, when the work-to-board work is repeatedly executed using the work-related data Rd after editing, the editorial unit 51 can obtain effects on the board-to-board work such as an increase / decrease in the error occurrence rate and an increase / decrease in the cycle time. It may be stored in association with the edited work-related data Rd. As a result, by applying the work-related data Rd after editing, for example, the error occurrence rate can be reduced and the mounting accuracy can be improved, while the cycle time can be increased. It is stored as related information that the time can be shortened significantly.

Further, when the work-related data Rd is edited in the first work machine M1 provided with the editing unit 51, the edited work-related data Rd is uploaded to the management device 40 and is stored in the storage unit 41 for editing work. It is stored with related information. As a result, the management device 40 recognizes that the work-related data Rd has been edited.

4-2. Judgment unit 52
As shown in FIG. 4, the data management system 50 includes a determination unit 52. When the work-related data Rd is edited, the determination unit 52 determines whether or not the editing of the work-related data Rd affects the work on the board by the second work machine M2. In the present embodiment, the determination unit 52 is provided in the management device 40 that manages the production line Ln.

More specifically, when the determination unit 52 recognizes that the work-related data Rd has been edited by the editorial unit 51 of the first work machine M1 by inputting the edited work-related data Rd, the other board-to-board work. Whether or not the edit should be reflected on the machine (second working machine M2) is determined based on the presence or absence of the influence of the edit. The work on the board by the second working machine M2 to be determined is the work on the board that is being executed or is scheduled to be executed, which is recognized based on the production plan D1 and the progress.

In addition, various modes can be adopted as a means for determining the presence or absence of the influence of the editing. For example, the determination unit 52 simply uses the work-related data Rd that is the same as or the same as the work-related data Rd edited by the editorial unit 51 for the work-to-board work by the second work machine M2. It may be determined that the editing of is affected. On the other hand, even if the work-related data Rd is the same or the same type, the editing of the work-related data Rd does not necessarily affect depending on the content of the work on the board by the second work machine M2.

Therefore, in the present embodiment, the determination unit 52 has an influence degree V2 of the editing of the work-related data Rd by the editing unit 51 and the editing of the work-related data Rd based on the content of the work on the board by the second working machine M2. When the reference value V1 set in advance is exceeded, it is determined that the editing of the work-related data Rd affects the work on the board by the second work machine M2.

That is, the determination unit 52 first acquires the content of editing based on the difference between the work-related data Rd before and after editing or the information related to the editing work. Next, the determination unit 52 acquires the contents of the work on the board being executed or scheduled to be executed by the second working machine M2 based on the production plan D1. Then, the determination unit 52 calculates the influence degree V2 of the editing based on the content of the editing and the content of the work on the board. For example, if the content of the edit is related to the part type Pa and the part type Pa is not included in the work on the board scheduled to be executed in the second work machine M2, the determination unit 52 sets the degree of influence V2 of the edit to 0. calculate.

On the other hand, when the on-board work scheduled to be executed in the second work machine M2 includes the mounting of the component type Pa, the determination unit 52 determines the degree of influence V2 based on the number of mounting of the component type Pa and the content of editing. Is calculated. At this time, the determination unit 52 may calculate the influence degree V2 based on the motive of the editing and the effect of the editing by using the information related to the editing work. For example, the determination unit 52 calculates the degree of influence V2 to be high if the editing content is related to the reduction of the error occurrence rate.

Further, the determination unit 52 determines that the editing of the work-related data Rd affects the work on the board by the second work machine M2 when the calculated influence degree V2 exceeds the preset reference value V1. That is, the determination unit 52 determines that the update process should be executed for the second work machine M2 in order to reflect the editing of the work-related data Rd. The determination unit 52 makes a determination for each of the plurality of second working machines M2 constituting the production line Ln. The determination unit 52 may use a plurality of types of reference values V1 to determine in stages whether or not the update process is necessary according to the degree of influence V2.

4-3. Information unit 53
As shown in FIG. 4, the data management system 50 includes a guide unit 53. The guide unit 53 guides the update of the work-related data Rd used in the second work machine M2 when the determination unit 52 determines that the editing of the work-related data Rd has an effect. In the present embodiment, the guide unit 53 is provided in each of the plurality of second working machines M2.

Specifically, the guide unit 53 indicates that the latest work-related data Rd exists for the work-related data Rd used for the work on the board being executed or scheduled to be executed by the own machine (second work machine M2). Displayed on the device 31. At this time, the guide unit 53 may also display various information when informing the operator of the update by the above display. The details of the displayed contents will be described later.

4-4. Notification unit 54
As shown in FIG. 4, the data management system 50 includes a notification unit 54. In the configuration in which the determination unit 52 and the guide unit 53 are provided in separate devices as in the present embodiment, the notification unit 54 gives work-related data to the second work machine M2 according to the determination result by the determination unit 52. Notify the update information T1 regarding the update of Rd. That is, the notification unit 54 notifies the second work machine M2, which is determined by the determination unit 52 among the plurality of second work machines M2, that the editing of the work-related data Rd affects the work on the board.

Further, the above-mentioned update information T1 may be the edited work-related data Rd itself, or may be information used to specify the edited content of the work-related data Rd. In the latter case, in the later update process, the edited work-related data Rd is downloaded from the management device 40 to the second work machine M2. Further, the notification unit 54 may transmit the edited work-related data Rd, the editing work-related information, the result of the determination by the determination unit 52, and intermediate information such as the influence degree V2 to the second work machine M2. The above-mentioned information transmission by the notification unit 54 may be performed, for example, in response to a request from the second working machine M2.

The guidance unit 53 of the second work machine M2, which has been notified by the notification unit 54, may also present the influence degree V2 when guiding the update of the work-related data Rd. Further, when the guide unit 53 guides the update of the work-related data Rd, at least one of the content of the work-related data Rd edited by the editorial unit 51 and the content of the work-related data Rd set in the second work machine M2 are set. It may be presented at the same time. As a result, the worker can determine whether or not to actually execute the update process by using the influence degree V2 or the like as a judgment material in addition to the existence of the latest work-related data Rd.

4-5. Update 55
As shown in FIG. 4, the data management system 50 includes an update unit 55. The update unit 55 accepts the necessity of updating the work-related data Rd guided by the guide unit 53, and executes the update process of the work-related data Rd as necessary. That is, when the worker determines that the edited work-related data Rd should be applied to the on-board work of the second work machine M2 and instructs the worker to execute the update process, the update unit 55 updates at a predetermined timing. Execute the process.

The update unit 55 may stop the work on the board by the second working machine M2 at the timing instructed by the operator and execute the update process. Further, the update unit 55 may set the timing for executing the update process based on the progress level V3 of the work on the board which is repeatedly executed in the second work machine M2. That is, the update unit 55 acquires, for example, a period during which processing (image processing, etc.) using the work-related data Rd to be updated is not executed (during transport of the substrate 91, etc.) based on the progress level V3 recognized by the own machine. do. Then, the update unit sets the timing so that the update process is executed during that period. As a result, the update process can be executed without stopping the work on the board.

In addition to executing the update process in parallel with the board-to-board work as described above, the update unit 55 may set various timings. For example, when the influence degree V2 of editing is high, but there is a margin until the time when the updated work-related data Rd is used, the update unit 55 is the first based on the production plan D1 and the progress degree V3 of the work on the board. (Ii) The time when the working machine M2 is put into hibernation may be estimated, and the hibernation time may be set as the update timing.

The update timing of the work-related data Rd may be automatically set by the update unit 55 as described above, or an instruction of the execution timing may be received together with the instruction of the operator to execute the update process. According to such a configuration, the update process can be executed at a more suitable timing, so that the initial productivity can be maintained. Further, since the worker instructs whether or not the final update process is necessary, it is possible to prevent unnecessary update process from being executed for the work-related data Rd of the second work machine M2, and the unnecessary update process can be performed. It is possible to prevent a decrease in production efficiency due to execution.

5. Data management processing by the data management system 50 The management processing of the work-related data Rd by the data management system 50 will be described with reference to FIGS. 4 and 5. First, the production plan D1 is generated in the host computer 60, and the type, quantity, and production order of the substrate products to be produced are set for each of the plurality of production lines Ln. The management device 40 acquires the production plan D1, the parts list D2 corresponding to the production plan D1, the control data D3, and the work-related data Rd from the host computer 60, and stores them in the storage unit 41.

The management device 40 sends necessary data to each of the anti-board working machines constituting the production line Ln. Specifically, the management device 40 sends the control data D3 and the work-related data Rd necessary for the mounting process executed by the predetermined component mounting machine 12 to the component mounting machine 12. At this time, for example, when the same type of parts are mounted on the substrate 91 in the mounting process by the plurality of component mounting machines 12, work-related data Rd that is at least partially common is sent to the respective component mounting machines 12. It is stored in the control device 30.

The worker starts this production process when the setup work related to the production process scheduled to be executed on the production line Ln is completed. The anti-board work machine including the component mounting machine 12 executes the anti-board work assigned to the own machine by using the work-related data Rd. The worker replenishes necessary consumables, collects unnecessary items, and handles errors so that the production process on the production line Ln can be continued.

Then, the operator determines that, for example, some parameters and the definition of the shape of the part should be adjusted based on the error generated during the execution of the mounting process by the component mounting machine 12 and the inspection result by the inspection machine 14. In this case, the work-related data Rd is edited by the anti-board work machine (that is, the first work machine M1 provided with the editing unit 51) having the work-related data Rd editing function. As shown in FIG. 5, the editing unit 51 accepts editing of work-related data Rd (S11). When the editing work is completed, the editing unit 51 uploads the edited work-related data Rd, the unique identification information, and the editing work-related information to the management device 40.

Next, when the work-related data Rd or the like is uploaded by the editorial unit 51 and stored in the storage unit 41, the management device 40 recognizes that the work-related data Rd has been edited in the first work machine M1 (S12). ). Subsequently, the determination unit 52 determines whether or not the editing of the work-related data Rd affects the work on the board by the second work machine M2 (S20). Specifically, the determination unit 52 determines the degree of influence V2 of the editing for each of the plurality of second working machines M2 based on the editing contents of the work-related data Rd and the contents of the work on the board in each of the second working machines M2. Calculate (S21).

Then, the determination unit 52 edits the work-related data Rd for each of the plurality of second work machines M2 by comparing the reference value V1 with the influence degree V2 for each of the plurality of second work machines M2. It is determined whether or not it affects the work (S22). The determination unit 52 stores the determination results for each of the plurality of second working machines M2 in the storage unit 41 together with the influence degree V2 calculated in S21.

The notification unit 54 notifies the second work machine M2 of the update information T1 regarding the update of the work-related data Rd according to the determination result by the determination unit 52 (S13). Here, the notification unit 54 notifies only the second work machine M2, which is determined by the determination unit 52 that the editing of the work-related data Rd affects the work on the board, among the plurality of second work machines M2. As the update information T1, the notification unit 54 notifies the identification information indicating the work-related data Rd before editing, the editing content, and the influence degree V2 calculated for the notification destination second work machine M2.
