Description

  The present invention relates to a technique for managing a component mounted on a board in a component mounter, and more particularly to a technique for managing a component whose expiration date can be used in a state where the component is mounted in a storage cabinet.

  2. Description of the Related Art There is known a component mounter that mounts a component mounted at a predetermined component mounting position on a substrate to produce a component-mounted substrate. In such a component mounter, a component according to the type of board to be produced is attached to a component mounting location of the component mounter. Then, the component at the component mounting location is used for mounting on the board. In addition, a storage shelf for storing components as shown in Patent Document 1 is used at a board production site. In particular, the technique of Patent Document 1 manages the inventory of parts by updating the number of parts in stock as the parts are stocked and unloaded.

  By the way, some components used in component mounters have a fixed expiration date because they deteriorate in quality over time. Therefore, it is possible to use a storage that suppresses deterioration with the passage of time. In other words, a worker can change the quality of a component by appropriately performing a component storage operation that removes the component from the component mounting location and stores it in the storage cabinet, or a component mounting task that removes the component from the storage cabinet and mounts it at the component mounting location. The parts can be used while being suppressed as much as possible.

  However, there are cases in which the expiration date of the component expires because the worker forgets to carry out the component storage work, or there is a case where board production is interrupted because the worker forgets to carry out the component mounting work. Alternatively, the worker may not be able to easily grasp the expiration date of the parts, and may not be able to perform these works at appropriate timing. On the other hand, the technique of Patent Document 1 is useful for managing the inventory of parts on the storage shelves, but cannot cope with such a case.

  The present invention has been made in view of the above problems, and a first object is to prevent an operator from forgetting to carry out a component storage work, and a first object to be able to prevent a worker from forgetting to carry out a component mounting work. (EN) Provided is a technique that achieves at least one of two purposes, and a third purpose such that an operator can easily grasp the expiration date of a part.

  The component management apparatus according to the first aspect of the present invention mounts a component on a board by mounting the component from a component mounting position where a component having an expiration date that can be used in a state of being taken out from a storage cabinet is mounted. The component mounter that produces a finished board is provided with a notification unit capable of executing a component storage notification requesting an operator to perform a component storage operation of removing a component from a component mounting location and storing it in a storage cabinet.

  A component management method according to a first aspect of the present invention uses a component by mounting the component on a substrate from a component mounting position where a component having a use-by date that can be used in a state of being taken out from a storage cabinet is mounted. A component storage notice that requests an operator to perform a component storage operation of removing a component from a component mounting location and storing it in a storage cabinet is executed for a component mounter that produces a completed board.

  In the first aspect (parts management device, parts management method) of the present invention configured as described above, the parts requesting the operator to execute the parts storage work in which the parts are removed from the parts mounting location and stored in the storage cabinet Storage notification is executed. Therefore, it is possible to prevent the worker from forgetting to perform the component storage work (first purpose).

  Further, the component management device may be configured to further include a control unit that causes the notification unit to execute the component storage notification according to the production plan of the board. As a result, it becomes possible for the worker to execute the component storage work at an appropriate timing according to the board production plan.

  Further, the control unit may configure the component management device so that the notification unit executes the component storage notification when the production of the board is stopped according to the production plan. Accordingly, the worker can perform the component storage work in response to the suspension of the production of the board and suppress the deterioration of the component during the suspension of the production of the board.

  Also, if the control unit confirms from the production plan that the production of the board will resume after it is temporarily stopped, it predicts the usage status of the parts from the production plan, and if the parts storage work is not executed, the parts will be attached during the production of the board after the restart. The component management device may be configured to cause the notification unit to execute the component storage notification in response to the production stoppage of the board when it is predicted that the unused component attached to the location will expire. Thereby, the worker can perform the component storage work in response to the stop of the production of the board, and can suppress the expiration of the unused component in the course of the board production after the restart.

  In addition, when the control unit predicts that the components mounted at the component mounting locations will be used up before the expiration date in the production of the board after restarting without executing the component storage work, the control unit will stop the production of the board. The component management device may be configured so that the notification unit does not execute the component storage notification. As a result, it is possible to prevent the worker from performing unnecessary parts storage work and reduce the burden on the worker.

  In addition, the control unit executes the usage schedule confirmation process to confirm whether the component mounted at the component mounting location will be used later in the production of the board under execution, and if it confirms that it will not be used after that, it stores the component. The component management device may be configured so that the notification unit is caused to execute the notification. As a result, the worker can carry out a component storage operation for a component that will not be used in the subsequent board production, and can suppress the deterioration of the component.

  In addition, multiple types of parts can be attached to the parts installation location, and the control unit executes the usage schedule confirmation process for each type of parts, and stores the parts of the types that are confirmed not to be used thereafter. The component management device may be configured so that the notification unit is caused to execute the notification. As a result, the worker can carry out the component storage work for the types of components that will not be used in the subsequent board production, and can suppress the deterioration of the components. At this time, the timing when it is confirmed that there is no plan to use it afterwards usually varies depending on the type of parts.Therefore, the timing at which the worker performs the parts storage work should be distributed among multiple types of parts. Therefore, the burden on the worker can be leveled.

  In addition, after the notification unit executes the component storage notification, the power management unit for prohibiting the power-off of the component mounter until it confirms that the work corresponding to the component storage work is executed is further provided with the component management. The device may be configured. Thereby, the worker can be urged to surely execute the component storage work.

  The component management apparatus according to the second aspect of the present invention uses the component to mount the component on the board from the component mounting position where the component having the expiration date that can be used in the state of being taken out from the storage is mounted. A component mounting notice that requests a worker to perform a component mounting operation to mount a component on a component mounting machine that produces a finished substrate and to mount the component on the component mounting location Section.

  A component management method according to a second aspect of the present invention is to mount a component by mounting the component on a board from a component mounting location where a component having a use-by date that can be used in a state of being taken out from a storage cabinet is mounted. A component mounting notice for requesting an operator to carry out a component mounting work for mounting a component on a component mounting location where a component is mounted on a component mounting machine for producing a completed substrate during the production of the substrate.

  In the second aspect (parts management device, parts management method) of the present invention configured as described above, the parts mounting requesting the operator to execute the parts mounting work in which the parts are taken out from the storage and mounted on the parts mounting location. Notification is performed during board production. Therefore, it is possible to prevent the operator from forgetting to execute the component mounting work (second purpose).

  In addition, the component management device may be configured to further include a control unit that causes the notification unit to execute the component attachment notification according to the production plan of the board during the production of the board. As a result, it becomes possible for the worker to execute the component mounting work at an appropriate timing according to the board production plan.

  Further, the control unit executes the use start confirmation process for confirming the scheduled time when the use of the component is started according to the production plan, and executes the component mounting notification to the notification unit before the scheduled time confirmed by the use start confirmation process. The component management device may be configured to do so. Therefore, the worker can accurately execute the component mounting work before the use of the component is started.

  In addition, a plurality of types of parts can be attached to the part attachment location, and the control unit executes the use start confirmation process for each type of parts, and for the types of parts whose scheduled time is confirmed in the use start confirmation process, The component management device may be configured such that the notification of the component attachment is executed by the notification unit. As a result, the worker can appropriately execute the component mounting work before the use of each type of component is started. At this time, since the timing of starting use usually varies depending on the type of parts, the timing at which the worker carries out the parts mounting work is distributed among a plurality of kinds of parts, which imposes a burden on the worker. Can also be leveled.

  Further, the notification unit can execute the setup notification requesting the operator to execute the setup work for mounting the component at the component mounting position before the production of the board, and the control unit notifies the setup preparation before the production of the board is started. The component management apparatus may be configured such that the first mode in which the notification unit executes the notification and the second mode in which the notification unit performs the component attachment notification during the production of the board can be selectively executed. ..

  In particular, the control unit predicts the usage status of the parts from the production plan before starting the production of the board, and even if the parts are attached to the parts attachment points before the start of the board production, the parts will be out of the expiration date in the production of the board after the start. The component management device may be configured to execute the first mode when it is predicted that the parts will be used up before. As a result, it is possible to reduce the burden on the operator during board production.

  In addition, the control unit predicts the usage status of the parts from the production plan before the production of the board is started. The component management device may be configured to execute the second mode when it is predicted that the expiration date of the unused component has passed. Accordingly, the worker can suppress the deterioration of the component by storing the component in the storage for a while from the start of the production of the board, and can accurately execute the component mounting work before the use of the component is started.

  The component management apparatus according to the third aspect of the present invention uses a component by mounting the component on a board from a component mounting position where a component having an expiration date that can be used in a state of being taken out from a storage cabinet is mounted. The component mounter for producing a finished board includes a confirmation unit for confirming the expiration date of the component to be mounted on the substrate, and a display unit for displaying to the operator the component corresponding to the expiration date confirmed by the confirmation unit.

  A component management method according to a third aspect of the present invention uses a component by mounting the component on a board from a component mounting position where a component having a expiration date that can be used in a state of being taken out from a storage cabinet is mounted. The expiration date of the component scheduled to be mounted on the board is displayed to the operator along with the corresponding component in the component mounter that produces the finished board.

  In the third aspect of the present invention thus configured, the expiration date of the component to be mounted on the board in the component mounter is displayed to the operator together with the component. Therefore, the worker can easily grasp the expiration date of the part (third purpose).

  In this specification, using a component means mounting the component on a substrate. Therefore, the unused component indicates a component not mounted on the board, and the used component indicates a component mounted on the board.

  Advantageous Effects of Invention According to the present invention, a first purpose is to suppress a supplier from forgetting to carry out a parts storage work, a second purpose is to prevent a worker from forgetting to carry out a parts mounting work, and a worker is allowed to carry out parts It is possible to realize at least one of the third purposes of making it possible to easily grasp the expiration date of the.

  FIG. 1 is a partial plan view schematically showing a component mounter. In the figure, XYZ orthogonal coordinates with the Z direction as the vertical direction are shown as appropriate. The component mounter 1 includes a pair of conveyors 12, 12 provided on a base 11. Then, the component mounter 1 mounts a component on the board S carried in from the upstream side in the X direction (board transfer direction) to the mounting processing position (the position of the board S in FIG. 1) by the conveyor 12, and mounts the component. The completed substrate S is carried out by the conveyor 12 from the mounting processing position to the downstream side in the X direction.

  The component mounter 1 is provided with a pair of Y-axis rails 131 and 131 extending in the Y direction, a Y-axis ball screw 132 extending in the Y-direction, and a Y-axis motor My that rotationally drives the Y-axis ball screw 132, and a head support member. 133 is fixed to the nut of the Y-axis ball screw 132 while being supported by the pair of Y-axis rails 131, 131 so as to be movable in the Y direction. An X-axis ball screw 134 extending in the X direction and an X-axis motor Mx that rotationally drives the X-axis ball screw 134 are attached to the head support member 133, and the head unit 14 can move in the X direction on the head support member 133. It is fixed to the nut of the X-axis ball screw 134 while being supported by. Therefore, the Y-axis motor My can rotate the Y-axis ball screw 132 to move the head unit 14 in the Y direction, or the X-axis motor Mx can rotate the X-axis ball screw 134 to move the head unit 14 in the X direction. it can.

  Two component attachment points 15 are arranged in the X direction on both sides of the pair of conveyors 12 in the Y direction. A plurality of tape feeders 151 are removably mounted side by side in the X direction with respect to each component mounting portion 15. Each tape feeder 151 has a small piece P of a component such as an integrated circuit, a transistor, or a capacitor. A reel around which a tape containing a plurality of (chip electronic components) is stored is arranged. Then, the tape feeder 151 supplies the component P in the tape by intermittently sending the loaded tape to the head unit 14 side. In particular, in the present embodiment, at least a part of the plurality of types of components P attached to the component attachment location 15 is a storage target component P having a use-by date that can be used in a state where the storage unit 3 described later is used. is there.

  The head unit 14 has a plurality of (four) mounting heads 141 arranged linearly in the X direction. Each mounting head 141 picks up and mounts the component P by a nozzle attached to the lower end. That is, the mounting head 141 moves above the tape feeder 151 and sucks the component P supplied by the tape feeder 151. Specifically, the mounting head 141 sucks the component P by lowering the nozzle until it abuts on the component P and then raising the nozzle while generating a negative pressure in the nozzle. Subsequently, the mounting head 141 moves above the substrate S at the mounting processing position to mount the component P on the substrate S. Specifically, the mounting head 141 mounts the component by lowering the nozzle until the component P contacts the substrate S and then generating atmospheric pressure or positive pressure in the nozzle.

  FIG. 2 shows a component mounting system including the component mounter of FIG. Subsequently, the component management executed by the component mounting system MS will be mainly described. Note that the component management described below manages the above-mentioned storage target component P among the plurality of types of components P used in the component mounter 1. However, in the following, the storage target component P is simply referred to as the component P. Abbreviated as appropriate.

  The component mounting system MS includes, in addition to the component mounting machine 1, a control device 2 and a storage 3. The control device 2 is a server computer, and controls the component mounting in the component mounter 1 as a whole. Further, the component mounting system MS includes an input device 21 and a display 22 connected to the control device 2. The input device 21 is composed of a mouse and a keyboard, and an operator can input information to the control device 2 by operating the input device 21. The display 22 is, for example, a liquid crystal display or the like, and the control device 2 can notify the operator of the content indicated by displaying an image or characters on the display 22. Further, the storage 3 stores the component P therein in order to suppress the deterioration of the component P due to oxidation or moisture.

The control device 2 includes a CPU (Central Processing Unit) and a RAM (Random Access Unit).
Memory 210), a storage unit 220 composed of an HDD (Hard Disk Drive), external devices such as the component mounter 1, the input device 21 and the display 22, and commands between the arithmetic unit 210. And an input / output unit 230 for inputting / outputting data. The storage unit 220 stores a management program 221, a production plan 222, and parts information 223. The management program 221 is a program for mounting components in each component mounter 1 and managing components P. The production plan 222 shows a plan for producing the component-mounted boards S in the component mounting system MS. The component information 223 indicates the type of the component P and the deadline of the component P in association with each other. The management program 221, the production plan 222, and the parts information 223 are stored in the storage unit 220 in advance by the worker.

  Then, the calculation unit 210 executes the management program 221 to build the control unit 211 and the notification unit 212 inside. The control unit 211 generally controls the control of the control device 2. The notification unit 212 appropriately executes a component storage notification requesting the worker to execute the component storage work and a component mounting notification requesting the worker to execute the component installation work. Here, the component storage work is a work of removing the component P from the component mounting location 15 and storing it in the storage 3, and the component mounting work is a work of taking out the component P from the storage storage 3 and mounting it in the component mounting location 15. is there. Specifically, the notification unit 212 executes the component storage notification by displaying the image or the character corresponding to the component storage notification on the display 22, and also displays the image or the character corresponding to the component attachment notification on the display 22. By doing this, the component attachment notification is executed. Thereby, the worker can appropriately perform the component storage work and the component mounting work by confirming the display on the display 22. Then, the control unit 211 causes the notification unit 212 to execute at least one of the component storage notification and the component attachment notification at a timing according to the production plan 222, thereby executing the component management.

  FIG. 3 is a flowchart showing a first example of component management executed by the control unit, and FIG. 4 is a diagram showing an example of operation executed by the flowchart of FIG. In FIG. 4, “working day” indicates a day on which each component mounter 1 is operated to produce a component-mounted board S, and “holiday” stops each component mounter 1 to mount a component-mounted board S. Indicates the days when no production is performed. Then, the storage unit 220 stores the plan (working days and holidays) shown in the calendar of FIG. 4 as the production plan 222.

  The flowchart of FIG. 3 is executed when the production of the board S in the component mounting system MS is started. In step S101, the control unit 211 determines based on the production plan 222 whether or not the production of the substrate S is stopped. When it is determined that the production of the board S is stopped (“YES” in step S101), the control unit 211 stores the components for all the storage target components P attached to each of the component mounting machines 1 included in the component mounting system MS. The notification is executed by the notification unit 212 (step S102). As a result, in the example of FIG. 4, the parts storage notification is issued when the production of the substrate S is stopped at the timing marked with a white circle, that is, on the working day (3 days, 10 days, 24 days) immediately before the holiday. Is executed. For example, when there is no night shift of the worker, the parts storage notification is executed in response to the production stop of the substrate S on the evening of the third, tenth, and twenty-fourth, and when the worker has the night shift, four days are given. The parts storage notification is executed in response to the production of the substrate S being stopped in the morning of the 11th and the 25th. Here, the specific timing of the component storage notification may be the same as the production stop of the board S, or may be immediately before or after the production stop of the board S.

  Then, by confirming the component storage notification displayed on the display 22, the worker can remove all the storage target components P from the component mounting points 15 of the component mounter 1 and store them in the storage 3. .. At this time, the control unit 211 confirms with respect to each component mounter 1 whether the storage target component P remains in the component mounting location 15. Then, the control unit 211 prohibits power-off of the component mounter 1 while the storage target component P remains in the component mounting location 15, while confirming that the storage target component P does not remain in the component mounting location 15. The prohibition of power-off is released in order from the completed component mounter 1.

  As described above, in the first example of component management, a component storage notification requesting the worker to perform the component storage operation of removing the component P from the component mounting location 15 and storing it in the storage 3 is executed. Therefore, it is possible to prevent the worker from forgetting to perform the component storage work.

  Further, the control unit 211 causes the notification unit 212 to execute the component storage notification according to the production plan 222 of the board S. As a result, it is possible for the worker to execute the component storage work at an appropriate timing according to the production plan 222 of the board S.

  Further, the control unit 211 causes the notification unit 212 to execute the component storage notification in response to the production of the substrate S being stopped according to the production plan 222. Thereby, the worker can perform the component storage work in response to the stop of the production of the board S, and suppress the deterioration of the component P during the stop of the production of the board.

  Further, after the notification unit 212 executes the component storage notification, the control unit 211 confirms whether or not the storage target component P remains at the component mounting location 15 to perform work according to the component storage work (component mounting). It is confirmed that the work of removing the part P from the location 15) has been executed. Then, the control unit 211 prohibits power-off of the component mounter 1 until it confirms that the work corresponding to the component storage work has been performed. Thereby, the worker can be urged to surely execute the component storage work.

  FIG. 5 is a flowchart showing a second example of component management executed by the control unit, FIG. 6 is a flowchart showing a third example of component management executed by the control unit, and FIG. 7 is a flowchart of FIGS. 5 and 6. It is a figure which shows an example of the operation | movement performed by. FIG. 7 shows the components Pa to Pc used in the production of the boards Sa to Sc of the respective types executed in the order from left to right, and the storage unit 220 produces the boards S shown in FIG. The order is stored as the production plan 222.

  The flowchart of FIG. 5 is executed when the production of the board S in the component mounting system MS is started. In step S201, the scheduled time Tb at which the use of each of the components Pa to Pc starts is confirmed based on the production plan 222 (use start confirmation processing). Then, in step S202, the component attachment notification execution time Tp is set at a time earlier than the scheduled time Tb by a predetermined margin time Tm (for example, 1 to 2 hours) (Tp = Tb-Tm). In this way, the execution time Tp of the component attachment notification is set for each of the components Pa to Pc. When the execution time Tp of any of the components Pa to Pc is reached (“YES” in step S203), the control unit 211 causes the notification unit 212 to execute the component attachment notification of the corresponding component P (step S204). As a result, the component attachment notification is executed before the time when the use of each of the components Pa to Pc is started. As a result, in the example of FIG. 7, the component attachment notification is displayed on the display 22 at the timing marked with a shaded circle. Specifically, the component mounting notification for the components Pa and Pc is displayed on the display 22 before the production of the substrate Sa that uses the components Pa and Pc is started, and the component mounting notification for the component Pb is the substrate that uses the component Pb. It is displayed on the display 22 before the start of Sb production. Therefore, the worker can attach the components Pa to Pc to the component attachment points 15 by the start of use.

  The flowchart of FIG. 6 is executed when the production of the board S in the component mounting system MS is started. In step S301, it is confirmed based on the production plan 222 whether or not the use of each of the components Pa to Pc is completed. Thus, in the production of the board S being executed, the usage schedule confirmation process for confirming whether each of the components Pa to Pc attached to the component attachment location 15 will be used later is executed. Then, when the use end of any of the components Pa to Pc is confirmed, the control unit 211 causes the notification unit 212 to execute the component storage notification of the corresponding component P (step S302). As a result, the parts storage notification is executed in response to the end of use of each of the parts Pa to Pc. As a result, the component storage notification is displayed on the display 22 at the timing marked with a white circle in FIG. Specifically, the component storage notification for the component Pa is displayed on the display 22 in response to the production end of the board Sa using the component Pa, and the component storage notification for the component Pb is production end for the board Sb using the component Pb. The part storage notification for the part Pc is displayed on the display 22 according to the end of production of the board Sc using the part Pc.

  As described above, in the second example of the component management, the component attachment notification requesting the operator to execute the component attachment work to take out the components Pa to Pc from the storage 3 and attach them to the component attachment location 15 is the production of the board S. To be executed. Therefore, it is possible to prevent the operator from forgetting to execute the component mounting work.

  Further, the control unit 211 causes the notification unit 212 to execute the component attachment notification according to the production plan 222 of the board S during the production of the board S. As a result, it becomes possible for the worker to execute the component mounting work at an appropriate timing according to the production plan 222 of the board S.

  In addition, the control unit 211 executes a use start confirmation process for confirming a scheduled time Tb at which the use of the components Pa to Pc is started according to the production plan 222, and the components before the scheduled time Tb confirmed by the use start confirmation process. The notification unit 212 is caused to execute the attachment notification. Accordingly, the worker can accurately execute the component mounting work before the use of the components Pa to Pc is started.

  Incidentally, a plurality of types of components Pa to Pc can be attached to the component attachment location 15. Therefore, the control unit 211 executes the usage start confirmation process for each type of the components Pa to Pc, and notifies the notification unit 212 of a component mounting notification regarding the components Pa to Pc of the type whose scheduled time Tb is confirmed in the usage start confirmation process. Let it run. As a result, the worker can accurately perform the component mounting work before the use of each type of components Pa to Pc is started. At this time, since the use start timing usually varies depending on the types of the components Pa to Pc, the timing at which the worker performs the component mounting work should be distributed among the plurality of types of components Pa to Pc. Therefore, the burden on the worker can be leveled.

  Further, in the third example of component management, the control unit 211 executes a usage schedule confirmation process for confirming whether or not the components Pa to Pc attached to the component attachment points will be used later in the production of the board S being executed. To do. Then, the control unit 211 causes the notification unit 212 to execute the parts storage notification for the parts Pa to Pc that are confirmed not to be used thereafter. As a result, the worker can perform the component storage work on the components Pa to Pc that are not planned to be used in the subsequent board production, and can suppress the deterioration of the components Pa to Pc.

  Incidentally, a plurality of types of components Pa to Pc can be attached to the component attachment location 15. Therefore, the control unit 211 executes a usage schedule confirmation process for each type of the components Pa to Pc, and causes the notification unit 212 to perform a component storage notification for the components Pa to Pc of the type confirmed not to be used thereafter. As a result, the worker can perform the component storage operation on the types of components Pa to Pc that are not planned to be used in the subsequent board production, and suppress the alteration of the components Pa to Pc. At this time, since the timing at which it is confirmed that there is no plan to use the parts normally varies depending on the type of the components Pa to Pc, the timing at which the worker performs the component storage work is different from that of the components Pa to Pc. Since it will be distributed among the workers, the burden on the worker can be equalized.

  FIG. 8 is a flowchart showing a fourth example of component management executed by the control unit, and FIG. 9 is a diagram showing an example of operation executed by the flowchart of FIG. The notation in FIG. 9 is the same as the notation in FIG. 4, and the storage unit 220 stores the plan shown in the calendar of FIG. 9 as the production plan 222.

  The flowchart of FIG. 8 is executed when the production of the board S in the component mounting system MS is started. The control unit 211 confirms based on the production plan 222 whether the production of the board S will be resumed after being temporarily stopped in accordance with the production stop of the board S (step S401). In the example of FIG. 9, step S401 is executed in response to the production of the substrate S being stopped on the working day immediately before the holiday.

  Then, when it is confirmed that the production of the board S is restarted (“YES” in step S401), the control unit 211 determines whether or not the component storage work is necessary in response to the production of the board S being temporarily stopped (step S402). ). Specifically, the control unit 211 predicts the usage status of the component P in the restarted board production based on the production plan 222, so that the component P currently attached to the component attachment point 15 is restarted in the board production. Predict the consumption time To used up in. Further, the control unit 211 confirms, based on the component information 223, a deadline time Tl at which the component P currently attached to the component attachment location 15 reaches the expiration date when the component P is not stored in the storage 3.

  Then, when the component P whose deadline time Tl is expected to be earlier than the consumption time To is attached to the component attachment location 15, it is determined that the component storage work is necessary ("YES" in step S402), and step S403. Proceed to. In step S403, the control unit 211 causes the notification unit 212 to execute the parts storage notification. At this time, the component storage notification may be executed for all the storage target components P attached to all the component mounters 1 included in the component mounting system MS, or the deadline time Tl is expected to be earlier than the consumption time To. The parts storage notification may be executed only for the selected parts P. On the other hand, when there is no part P at the part mounting location 15 where the deadline time Tl is expected to be earlier than the consumption time To, it is determined that the part storage work is unnecessary (“NO” in step S402), and step S403 is executed. Without that, the flowchart of FIG. 8 ends.

  As a result, in the example of FIG. 9, the board production suspension period is as short as 2 days on 3 and 24 days of each working day (3 days, 10 days, and 24 days) immediately before the holiday, so the component storage work is performed. Is determined to be unnecessary and the parts storage notification is not executed. On the other hand, for 10 days, the board production suspension period is as long as 9 days, so it is determined that the parts storage operation is necessary, and the parts storage notification is executed.

  As described above, in the fourth example of component management, the control unit 211 predicts the usage status of the component P from the production plan 222 when confirming from the production plan 222 that the production of the board S is resumed after being temporarily stopped. Then, if the control unit 211 predicts that the unused part P attached to the component mounting portion 15 will expire in the production of the board S after restarting unless the component storage work is executed, in other words, it is not used. When it is predicted that the expiration date of the unused component P will pass with the component P remaining in the component attachment location 15, the notification unit 212 is caused to execute the component storage notification in response to the production stop of the board S. Accordingly, the worker can perform the component storage work in response to the stop of the production of the board S, and can prevent the expiration date of the unused component P from passing during the production of the board after the restart.

  In addition, if the control unit 211 predicts that the component P attached to the component attachment location 15 will be used up before the expiration date in the production of the board S after restarting without executing the component storage work, in other words, When it is predicted that the unused part P will be lost from the part mounting location 15 before its expiration date, the notification unit 212 is not caused to execute the part storage notification when the production of the board S is stopped. As a result, it is possible to prevent the worker from performing unnecessary parts storage work and reduce the burden on the worker.

  FIG. 10 is a diagram schematically showing a fifth example of component management executed by the control unit. In FIG. 10, different symbols 1A to 1C are used to distinguish the three component mounters 1. In the fifth example of component management, the control unit 211 causes the notification unit 212 to display the list shown in FIG. 10 on the display 22. That is, the control unit 211 identifies each component P scheduled to be used by each of the component mounters 1A to 1C based on the production plan 222, and also confirms the expiration date of each identified component P based on the component information 223. Then, the control unit 211 creates the list of FIG. 10 in which the name of each component P and the expiration date are associated with each other, and causes the display 22 to display the list. As a result, the worker preferentially executes the parts storage work for the parts P with an early expiration date to store the parts P in the storage 3, or gives priority to the parts P with an late expiration date. It is possible to execute the component mounting work and mount the component P at the component mounting location 15.

  As described above, in the fifth example of component management, the expiration date of the component P scheduled to be mounted on the board S in the component mounter 1 is displayed to the operator together with the component P. Therefore, the worker can easily grasp the expiration date of the part P.

  As described above, in the present embodiment, the control device 2 corresponds to an example of the “component management device” of the present invention, and the control unit 211 corresponds to an example of the “control unit” or the “power management unit” of the present invention. The notification unit 212 corresponds to an example of the “notification unit” of the present invention, the display 22 corresponds to an example of the “display unit” of the present invention, and the component mounter 1 is an example of the “component mounter” of the present invention. The component mounting location 15 corresponds to an example of the “component mounting location” of the present invention, the storage 3 corresponds to an example of the “storage” of the present invention, and the substrate S corresponds to the “substrate” of the present invention. This corresponds to an example, and the part P corresponds to an example of the “part” of the present invention.

  It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made to the above without departing from the spirit thereof. Therefore, for example, the control device 2 may be configured to have a function of assisting the setup work performed by the worker before the production of the substrates S is started. In such a modified example, the notification unit 212 can execute the setup notification requesting the operator to perform the setup work for mounting the component P on the component mounting location 15 before the production of the board S. Then, the control unit 211 causes the notification unit 212 to execute a setup notification before the production of the boards S is started, and the second mode (to manage the parts management is performed by the notification unit during the production of the boards S). Second example) and can be selectively executed.

  In particular, the control unit 211 predicts the usage status of the component P from the production plan 222 before the production of the board S is started. Then, if it is predicted that the component P will be used up before the expiration date in the production of the board S after the start even if the component P is attached to the component attachment location 15 before the production of the board S is started, the first mode is executed. .. As a result, it is possible to reduce the burden on the operator during board production.

  On the other hand, if the control part 211 attaches the component P to the component attachment location 15 before the production of the board S starts, the expiration date of the unused component P attached to the component attachment location 15 in the production of the board S after the start has passed. Then, when it is predicted, the second mode is executed. With this, the worker can suppress the alteration of the component P by storing the component P in the storage 3 for a while after the production of the substrate S is started, and accurately execute the component mounting work before the use of the component P is started. can do.

  Further, the specific execution mode of the component storage notification by the notification unit 212 is not limited to the display on the display 22 described above. Therefore, by blinking or turning on a warning light provided on the tape feeder 151 loaded with the part P to be notified of the parts storage or a warning light provided at the mounting position of the tape feeder 151, the parts storage notification is given. May be executed.

  Further, in the component mounter 1, the tape feeder 151 can be attached to the component attachment location 15 using, for example, a carriage described in Japanese Patent Laid-Open No. 2013-125880. Therefore, the parts storage notification may be executed by turning off the clamp of the tape feeder 151 to the dolly or automatically removing the tape feeder 151 from the dolly.

  Further, the specific execution mode of the component attachment notification by the notification unit 212 is not limited to the display on the display 22 described above. Therefore, the component attachment notification may be given by blinking or turning on a warning light provided at a planned mounting position of the tape feeder 151 in which the component P to be the component attachment notification target is loaded. Alternatively, by mounting the tape feeder 151 at the planned mounting position by turning off the clamp of the cart at the planned mounting position of the tape feeder 151 loaded with the component P to be notified of the component mounting, You may give a notification.

  Further, it is not necessary to configure the control device 2 to be able to execute both the component storage notification and the component mounting notification, and the control device 2 may be configured to be capable of executing only one of these notifications.

  The specific configuration of the control device 2 is not limited to the above server computer. Therefore, the control device 2 can be configured by a portable information terminal device such as a smartphone or a tablet.

  Further, the application target of the component management described above is not limited to the component P supplied by the tape feeder 151, and may be the component P supplied by the tray feeder described in JP 2013-229420A or the like.
