Description

  According to the present invention, a component mounting apparatus that takes a component that is sequentially supplied to a component supply position by a feeder that is detachably mounted to the component supply position and transfers the component to a substrate is mounted to the component supply position. The present invention relates to a technology that supports the determination of a feeder type.

  2. Description of the Related Art Generally, a component mounting apparatus that mounts components on a substrate by picking up components that are sequentially supplied to a component supply position with a mounting head and transferring them onto the substrate is used. In such a component mounting apparatus, a certain amount of time (component supply time) is required from the start of supply of components to the component supply position to completion. For this reason, as pointed out in Patent Document 1, there is a case in which a waiting time for the mounting head to wait for a request for a feeder component is generated because the feeder parts cannot be supplied in time. The occurrence of the standby time is one factor that hinders the efficiency of component mounting on the board. This is because, while waiting for component supply during the standby time, the mounting head cannot mount the component, and component mounting on the substrate does not proceed, so that completion of component mounting on the substrate is delayed.

JP-A-8-78890

  In order to cope with such a problem, it is conceivable to use a high-performance type feeder with a short component supply time in a component mounting apparatus. However, in a production site, for example, a situation is assumed in which a feeder is reused between a plurality of component mounting apparatuses or component mounting is performed using a component mounting apparatus having a plurality of component supply positions. It is necessary to have as many feeders as possible. At this time, it is difficult to arrange all the feeders with high-performance types for reasons such as cost. Therefore, it is normal that a plurality of types of feeders having different parts supply times are mixedly held.

  The present invention has been made in view of the above problems, so that an appropriate type of feeder can be mounted on a component mounting apparatus from among a plurality of types of feeders whose component supply times are different from each other, and the waiting time of the mounting head can be suppressed. An object of the present invention is to provide a technique for supporting a setup operation of a user who mounts a feeder on a component mounting apparatus.

  In order to achieve the above object, the feeder setup support device according to the present invention takes the components that are sequentially supplied to the component supply position by the feeder, which is detachably attached to the component supply position, and transfers them to the substrate. In the feeder setup support device that supports the determination of the feeder to be mounted at the component supply position for the component mounting device to be mounted, when the component mounting process for mounting the component on the board is executed, it is scheduled to be taken at the component supply position A standby time prediction unit that predicts a standby time for the mounting head to wait for the component to be supplied to the component supply position by the feeder, and a component that can be transferred to the component supply position by the mounting head in the component mounting process From several types of feeders that have different parts supply times from the start of supply of parts to the supply position to completion, The Chakusuru feeder and a viable feeder determining section feeder determination processing of determining, based on the waiting time.

  In order to achieve the above-described object, the feeder setup support method according to the present invention takes the components that the feeder, which is detachably attached to the component supply position, sequentially supplies to the component supply position with the mounting head and transfers it to the substrate. In the feeder setup support method for supporting the determination of the feeder to be mounted at the component supply position for the component mounting apparatus to be mounted, when the component mounting process for mounting the component on the board is executed, it will be taken at the component supply position The process of predicting the waiting time for the mounting head to wait for the component to be supplied to the component supply position by the feeder, and the component transferred by the mounting head in the component mounting process can be supplied to the component supply position and to the component supply position. Among the feeders of different types that have different parts supply times from the start to the end of the supply of parts, The feeder determination processing for determining based on the over Da to waiting time and an executable process.

  In order to achieve the above object, the feeder setup support program according to the present invention takes, with a mounting head, components that are sequentially supplied to a component supply position by a feeder that is detachably attached to the component supply position, and transfers it to the substrate. In a feeder setup support program that causes a computer to determine a feeder to be mounted at a component supply position for a component mounting apparatus to be mounted, it is scheduled to be taken at the component supply position when executing a component mounting process for mounting a component on a board The process of predicting the waiting time for the mounting head to wait for the component to be supplied to the component supply position by the feeder, and the component transferred by the mounting head in the component mounting process can be supplied to the component supply position and to the component supply position. Parts supply from multiple types of feeders with different parts supply times from the start of supply to completion And capable of executing feeder determination processing of determining, based on the waiting time feeder mounting process on location, it causes the computer to execute.

  Further, in order to achieve the above object, the recording medium according to the present invention records the feeder setup support program so that it can be read out by a computer.

  In the invention thus configured (feeder setup support device, feeder setup support method, feeder setup support program, recording medium), the components that the feeder sequentially supplies to the component supply position are picked up by the mounting head and transferred to the substrate. Included. In such a configuration, the waiting time of the mounting head is generated because the component supply of the feeder is not in time for the acquisition timing at which the mounting head picks up the component at the component supply position. However, in other words, if the feeder can supply components according to the acquisition timing of the mounting head, the occurrence of the standby time is suppressed. In other words, any feeder type that can supply components according to the acquisition timing of the mounting head is sufficient.

  Paying attention to this point, in the present invention, when a component mounting process for mounting a component on a substrate is executed, a waiting time for the mounting head to wait for component supply by the feeder is predicted. Then, a feeder to be attached to the component supply position is determined based on the standby time from a plurality of types of feeders having different component supply times. Therefore, a feeder that supplies components at an appropriate component supply time according to the expected standby time, in other words, a feeder that supplies components according to the acquisition timing of the mounting head, is provided with respect to the component supply position. You can decide to wear it. As a result, the user who mounts the feeder on the component mounting apparatus can suppress the waiting time of the mounting head by mounting an appropriate type of feeder from a plurality of types of feeders having different component supply times on the component mounting apparatus. Setup work can be supported.

  At this time, the standby time prediction unit predicts a standby time that occurs when the component mounting process is executed under the condition that a feeder belonging to one specific type of the plurality of types is mounted on the component supply position. The feeder determination unit sets the feeder setup support device to execute the feeder determination process based on the difference in the component supply time between the types other than the specific type and the specific type among the plurality of types, and the standby time. It may be configured. Thus, the standby time can be predicted with relatively high accuracy by predicting the standby time that occurs when the component mounting process is executed under the condition where the feeder is mounted on the component supply position. However, if the standby time is predicted for each of the case where all types of feeders are attached, it may take a long time to complete the prediction of the standby time. On the other hand, in this configuration, the standby time is predicted when a feeder belonging to one specific type of a plurality of types is attached, so that the time required to complete the standby time prediction can be suppressed. In addition, since the feeder determination process is executed based on the difference in parts supply time between the types other than the specific type and the specific type among the multiple types, and the standby time, the standby time is predicted for all of the multiple types. Even if it is not, it is possible to determine that a feeder of a type that supplies a component with an appropriate component supply time corresponding to the standby time is mounted to the component supply position. In this way, it is possible to determine to attach an appropriate type of feeder to the component supply position while suppressing the time required to complete the standby time prediction.

  At this time, the standby time prediction unit obtains the maximum value of the standby time as the maximum standby time, and the feeder determination unit determines that the high-speed type feeder whose component supply time is shorter than the maximum standby time than the specific type of feeder is a plurality of types of feeders. In this case, the feeder setup support device may be configured to execute the feeder determination process by determining that the high-speed type feeder is mounted at the component supply position. Such a high-speed type feeder can supply components with a component supply time sufficiently early with respect to the maximum waiting time of the mounting head. Therefore, by determining that the high-speed type feeder is mounted on the component supply position, it is possible to more reliably suppress the occurrence of the waiting time of the mounting head.

  In addition, when there are a plurality of high-speed types for the component supply position, the feeder determination unit determines to install a high-speed type feeder having the longest component supply time from among the plurality of high-speed types at the component supply position. Thus, the feeder setup support apparatus may be configured to execute the feeder determination process. In other words, when there are a plurality of high-speed types, any of the high-speed type feeders can supply components at a timing sufficient to reliably suppress the waiting time of the mounting head. Therefore, by determining that the high-speed type feeder having the longest component supply time is to be mounted among these high-speed type feeders, it is possible to mount a feeder having an appropriate capacity without excess or deficiency.

  In addition, when there is no high-speed type for the component supply position, the feeder determination unit determines that the feeder of the type with the shortest component supply time from among a plurality of types is to be attached to the component supply position, thereby determining the feeder. You may comprise a feeder setup assistance apparatus so that a process may be performed. Thus, even when the high-speed type feeder as described above does not exist at the component supply position, it is possible to suppress the waiting time of the mounting head.

  Further, the standby time prediction unit may configure the feeder setup support device so as to set a type that has the longest component supply time among a plurality of types as a specific type. Such a configuration is suitable for accurately predicting the estimated time of the mounting head.

  Alternatively, when all of the plurality of types of feeders are high-speed type feeders, the feeder determination unit may stop the feeder determination process and attach any of the plurality of types of feeders to the component supply position. The setup support device may be configured to determine as follows. In such a configuration, the trouble of preparing one type of feeder at the time of setup can be saved, so the burden on the user can be reduced.

  Moreover, you may comprise a feeder setup assistance apparatus so that the display part which displays the content which the feeder determination part determined may further be provided. In such a configuration, the user can appropriately perform the setup while confirming the display on the display unit, and the workability of the user can be improved.

  In addition, for a component mounting apparatus provided with a plurality of component supply positions, in a feeder setup support device that supports the determination of a feeder to be attached to each of the plurality of component supply positions, the standby time prediction unit includes a plurality of component supplies. The feeder setup support device may be configured such that the standby time is predicted for each position, and the feeder determination unit executes a feeder determination process by combining a plurality of types of feeders for each of a plurality of component supply positions. Thus, the present invention can be suitably applied to a component mounting apparatus provided with a plurality of component supply positions. That is, by performing an operation of predicting the standby time and executing the feeder determination process based on the standby time for each of the plurality of component supply positions, the components are supplied at an appropriate component supply time corresponding to the standby time. A type of feeder can be determined to be installed at each component supply position. As a result, the feeder is mounted on the component mounting device so that an appropriate type of feeder can be mounted at each component supply position from multiple types of feeders with different component supply times and the waiting time of the mounting head can be suppressed. It is possible to support the user's setup work.

  By the way, the number of feeders owned by the user is limited. Therefore, it may be configured such that a feeder to be mounted at each of a plurality of component supply positions can be determined in consideration of such circumstances. Specifically, it further includes a remaining number management unit that manages, for each type, the number of feeders that have not yet been determined to be installed at the component supply position, and the remaining number management unit executes feeder determination processing. Each time, the number of feeders determined to be installed at the component supply position by the feeder determination process is subtracted from the available remaining number of the corresponding type, and the feeder determining unit selects a type with one or more available remaining numbers. You may comprise a feeder setup assistance apparatus so that the feeder determination process based on the combined several types of feeder may be performed in order with respect to each component supply position. In such a configuration, according to the number of feeders owned by the user, it is possible to appropriately determine the feeders to be attached to each of the plurality of component supply positions.

  In this configuration, the feeder type is determined in order for each component supply position to determine the type of feeder to be mounted. Each time the feeder determination process is executed, the remaining number of feeders is subtracted. Therefore, the parts supply position of the first board in the order of receiving the feeder determination process is subject to the feeder determination process in a situation where the remaining number of feeders of each type is large. It is in. Conversely, in the order of receiving the feeder determination process, the part supply position at the end of the process is determined to install a feeder whose component supply time is relatively slow because the feeder determination process is performed when the number of remaining feeders of each type is small or zero. Tend to be. In other words, the earlier the order in which the component supply position is subjected to the feeder determination process, the faster the component supply time of the type of feeder whose attachment to the component supply position is determined.

  Therefore, the standby time prediction unit obtains, for each component supply position, an accumulated standby time obtained by accumulating the standby time generated when the component mounting process is executed, and the feeder determination unit prioritizes the component supply position having a long cumulative standby time. The feeder setup support device may be configured to execute the feeder determination process. In such a configuration, the feeder supply process is performed at an earlier stage as the component supply position has a longer expected accumulated standby time, and therefore, it is determined to install a feeder with a relatively short component supply time. Accordingly, it is possible to quickly supply parts with a feeder having a short part supply time and effectively compress the accumulated standby time predicted to be long. As a result, it is possible to reduce the tact time of the component mounting apparatus.

  Incidentally, the period for which the waiting time is accumulated can be set as appropriate. Therefore, the standby time prediction unit may configure the feeder setup support device so as to obtain the accumulated standby time during the period in which the component mounting process is executed based on the production program that defines the procedure for mounting the component on the board. good. Alternatively, the standby time prediction unit configures the feeder setup support device so as to obtain an accumulated standby time during a period in which the component mounting process is executed based on a plurality of production programs that are executed in sequence with different procedures. May be.

  Further, in a feeder setup support device that supports the determination of a feeder to be mounted at each of a plurality of component supply positions of a plurality of component mounting devices for a plurality of component mounting devices that sequentially perform mounting of components on a board. The determination unit may configure the feeder setup support device so that the feeder determination processing is executed in order from the component mounting device with a slow cycle time. In such a configuration, a component mounting apparatus having a longer cycle time is subjected to feeder determination processing at an earlier stage, and therefore, it is determined to mount a feeder of a type having a relatively short component supply time. Therefore, it is possible to quickly supply parts with a feeder having a short part supply time, and to effectively compress the cycle time predicted to be long.

  In addition, when a setup operation for replacing the feeder occurs, the feeder determination unit prohibits sharing the feeder exchanged in the setup operation between the component mounting processes before and after the setup operation, and then determines the feeder. You may comprise a feeder setup assistance apparatus so that a process may be performed. In such a configuration, the feeder to be mounted on the component supply position is determined so that the feeder to be replaced in the setup operation is not shared by the component mounting process before and after the setup operation. Therefore, the component mounting process after the setup work can be quickly started.

  According to the present invention, the feeder is mounted on the component mounting apparatus so that an appropriate type of feeder can be mounted on the component mounting apparatus from among a plurality of types of feeders whose component supply times are different from each other, and the waiting time of the mounting head can be suppressed. It is possible to support the user's setup work.

  The feeder setup support technology according to the present invention relates to a component mounting apparatus in which a feeder, which is detachably attached to a component supply position, sequentially supplies components supplied to the component supply position by a mounting head and is transferred to a substrate. This is to support the determination of a feeder to be attached to the supply position. Therefore, in the following, a detailed configuration of the component mounting apparatus will be described, and then a specific configuration for executing the feeder setup support technology according to the present invention will be described.

  FIG. 1 is a plan view showing a schematic configuration of a component mounting apparatus to which the present invention is applicable. FIG. 2 is a partial front view of the component mounting apparatus shown in FIG. FIG. 3 is a block diagram showing the main electrical configuration of the component mounting apparatus shown in FIG. The component mounting apparatus 1 shown in these drawings has a configuration in which components are mounted on the surface of a board S carried into the apparatus, and the board S on which the parts are mounted is carried out of the apparatus. In FIG. 1 and FIG. 2 and the drawings shown below, XYZ orthogonal coordinate axes with the Z-axis direction as the vertical direction are shown as appropriate in order to clarify the directional relationship between the drawings.

  In the component mounting apparatus 1, the substrate transport mechanism 12 is disposed on the base 11, and the substrate S can be transported in a predetermined transport direction X. More specifically, the substrate transport mechanism 12 has a pair of conveyors 121 and 121 that transport the substrate S from the right side to the left side of FIG. And the conveyors 121 and 121 carry the board | substrate S according to the command from the drive control part 210 of the control unit 200. FIG. Specifically, the conveyors 121 and 121 stop the substrate S carried in from the outside of the apparatus at a predetermined work position 10 (the position of the substrate S shown in FIGS. 1 and 2) and fix it by a fixing means (not shown). Hold horizontally. When the head unit 16 to be described later completes the attachment of components to the surface of the substrate S held horizontally at the work position 10, the conveyors 121 and 121 carry the substrate S out of the apparatus.

  On the front side (+ Y axis direction side) and the rear side (−Y axis direction side) of the conveyors 121, 121, the component supply unit 14 is arranged. The component supply unit 14 is provided with a plurality of set positions Ps (feeder set positions) in which the feeder 141 can be detachably mounted side by side in the X-axis direction, and the feeder 141 is attached to each set position Ps. A plurality of feeders 141 are arranged in the X-axis direction. The feeder 141 has the same configuration as the tape feeder described in, for example, Japanese Patent Application Laid-Open No. 2009-302475. In other words, the feeder 141 is a tape feeder provided with a reel (not shown) around which a tape storing and holding components is wound, and the tape is a small chip component such as an integrated circuit (IC), a transistor, or a capacitor. Are stored and held at predetermined intervals. Then, the feeder 141 rotates the reel to intermittently send out the component toward the component supply position Pp at the set position Ps that is mounted, and supplies the component to the component supply position Pp. As a result, the mounting head 160 of the head unit 16 can pick up a component at the component supply position Pp using the suction nozzle 161.

  Incidentally, the feeder 141 sends out the components intermittently to the component supply position Pp by feeding out the components at a constant feed speed and at a constant feed pitch. At this time, the component supply time from the start of feeding (supply) of the component to the component supply position Pp by the feeder 141 to the completion corresponds to a value obtained by dividing the feed pitch by the feed speed. In this embodiment, a plurality of types of feeders 141 whose component supply times are different from each other are detachable from each set position Ps, and the user can select an appropriate type of feeder at each set position Ps in the setup operation. 141 can be mounted. Note that the feeder 141 can be attached and detached collectively by a feeder carriage that holds a plurality of feeders 141 side by side.

  The head unit 16 conveys the component sucked and held by the suction nozzle 161 of the mounting head 160 to the substrate S and transfers it to a mounting target location on the surface of the substrate S. Specifically, the head unit 16 includes six mounting heads 160F arranged in a line in the X-axis direction on the front side, and six mounting heads 160R arranged in a line in the X-axis direction on the rear side. A total of 12 mounting heads 160 are provided. That is, as shown in FIGS. 1 and 2, in the head unit 16, six mounting heads 160F extending in the vertical direction Z are provided in a row at an equal pitch in the X-axis direction. Further, a rear row that is configured in the same manner as the front row is provided on the rear side (−Y-axis direction side) with respect to the mounting head 160F. The mounting head 160F and the mounting head 160R are arranged with a half-pitch shift in the X-axis direction, and are arranged in a zigzag shape in plan view as shown in FIG. Therefore, when viewed from the Y-axis direction, as shown in FIG. 2, the twelve mounting heads 160 are arranged in a line in the X-axis direction without overlapping each other. As described above, since the plurality of mounting heads 160 are mounted on the head unit 16, the head unit 16 can pick up a plurality of components from the component supply unit 14 at a time.

  The front end portion of each mounting head 160 to which the suction nozzle 161 is attached can communicate with any one of the negative pressure generating device, the positive pressure generating device, and the atmosphere via the pressure switching mechanism 17. The grip controller 220 of the control unit 200 can switch the pressure applied to the tip of the mounting head 160 by controlling the pressure switching mechanism 17. Therefore, when a negative pressure suction force from the negative pressure generator is applied to the tip portion of the mounting head 160 by pressure switching, the suction nozzle 161 attached to the tip portion sucks and holds the component. Conversely, when positive pressure from the positive pressure generator is applied to the tip of the mounting head 160, the suction holding of the component by the suction nozzle 161 is released, and the component is mounted on the substrate S. And after mounting components, the suction nozzle 161 is opened to the atmosphere. As described above, in the head unit 16, components can be attached and detached by controlling the negative pressure adsorption force and the positive pressure supply by the grip control unit 220.

  A Z-axis servomotor Mz and an R-axis servomotor Mr are connected to each of the mounting heads 160 via a drive mechanism (not shown). That is, the mounting head 160 moves up and down (moves in the vertical direction Z) in response to a driving force from the Z-axis servomotor Mz via a nozzle lifting drive mechanism (not shown). Therefore, the drive control unit 210 controls the Z-axis servo motor Mz to lower the height when the component is picked up or mounted (lower end) and the height when the component is conveyed (up end). The mounting head 160 (the suction nozzle 161) can be moved up and down. Further, the mounting head 160 can rotate around the central axis of the nozzle (rotation in the R direction in FIG. 2) by receiving a driving force from the R-axis servomotor Mr via a nozzle rotation driving mechanism (not shown). . Therefore, the drive control unit 210 can adjust the rotation angle of the component sucked by the suction nozzle 161 by controlling the R-axis servo motor Mr.

  Thus, the Z-axis servo motor Mz and the R-axis servo motor Mr provided on each mounting head 160 are provided with the Z-axis encoder Ez and the R-axis encoder Er, respectively. Therefore, the drive control unit 210 can grasp the height (Z coordinate) of the mounting head 160 (the suction nozzle 161) in the vertical direction Z based on the output of the Z-axis encoder Ez. Further, the drive control unit 210 can grasp the rotation (R coordinate) of the mounting head 160 (the suction nozzle 161) in the rotation direction R based on the output of the R-axis encoder Er.

  The head unit 16 holding these mounting heads 160 can move two-dimensionally within a horizontal plane (in a plane including the X axis and the Y axis) perpendicular to the vertical direction Z over a predetermined range of the base 11. . That is, the head unit 16 is supported so as to be movable along the X axis with respect to the mounting head support member 163 extending in the X axis direction. Further, both ends of the mounting head support member 163 are supported by a fixed rail 164 in the Y-axis direction, and are movable along the fixed rail 164 in the Y-axis direction. The head unit 16 is driven in the X-axis direction by the X-axis servo motor Mx via the ball screw 166, and the mounting head support member 163 is driven in the Y-axis direction by the Y-axis servo motor My via the ball screw 168. The Therefore, the drive control unit 210 drives and controls the X-axis servo motor Mx and the Y-axis servo motor My, so that the head unit 16 can be moved to a predetermined position in the XY plane (in the horizontal plane). As a result, it is possible to perform an operation of moving the head unit 16 as appropriate and transporting the component sucked by the mounting head 160 from the component supply unit 4 to the mounting target location.

  Thus, the X-axis servo motor Mx and the Y-axis servo motor My that drive the head unit 16 are provided with the X-axis encoder Ex and the Y-axis encoder Ey, respectively. Therefore, the drive control unit 210 can grasp the position (X coordinate) of the head unit 16 in the X-axis direction based on the output of the X-axis encoder Ex. Further, the drive control unit 210 can grasp the position (Y coordinate) of the head unit 16 in the Y axis direction based on the output of the Y axis encoder Ey. That is, the XY coordinates of the head unit 16 can be grasped from the outputs of the encoders Ex and Ey. Further, the drive control unit 210 stores a positional relationship between the head unit 16 and each of the mounting heads 160 mounted thereon. Therefore, the drive control unit 210 can also grasp the XY coordinates of each mounting head 160 based on the positional relationship and the outputs of the encoders Ex and Ey.

  As shown in FIG. 3, the component mounting apparatus 1 includes a display 191 and an input device 192 that function as an interface with a user. The display 191 has a function as an input terminal that is configured with a touch panel and receives an input from a user, in addition to a function of displaying an operation state or the like of the component mounting apparatus 1. The input device 192 includes a mouse and a keyboard, and fulfills a function of receiving input from the user. The input / output control for the display 191 and the input device 192 is executed by the input / output control unit 240 of the control unit 200.

  The overall operation of the component mounting apparatus 1 configured as described above is comprehensively controlled by the main control unit 250. That is, the main control unit 250 controls the entire apparatus 1 by exchanging signals with each unit of the control unit 200 via the bus 270 based on programs and data stored in the storage unit 260. Specifically, the production program 262 is stored in the storage unit 260. The production program 262 is a program for controlling the mounting head 160 and the like in order to attach the component to the mounting target location of the substrate S. The production program 262 includes a mounting procedure, etc. Information is incorporated.

  The above is the outline of the component mounting apparatus 1. Subsequently, the feeder setup support device that determines the type (feeder type) of the feeder 141 to be attached to each of the plurality of set positions Ps provided in the component mounting apparatus 1 and supports the feeder setup work by the user. The configuration and operation will be described in detail. FIG. 4 is a block diagram schematically showing the configuration of a host computer corresponding to the feeder setup support apparatus of the present invention.

  The host computer 300 executes the feeder setup support program 500 recorded on the recording medium 400 to determine the type of the feeder 141 to be mounted at the set position Ps. Incidentally, as the recording medium 400, various media such as a CD (Compact Disc), a DVD (Digital Versatile Disc), and a USB (Universal Serial Bus) memory can be used. Also, the feeder setup support program 500 may be supplied to the host computer 300 by downloading from the server without using the recording medium 400.

  The host computer 300 includes a calculation unit 310, a display 320, and a storage unit 330. The calculation unit 310 includes a CPU (Central Processing Unit) and a memory, and executes the feeder setup support program 500 read from the recording medium 400 to determine the type of the feeder 141 to be mounted at the set position Ps. The display 320 displays the execution result of the feeder setup support program 500 to the user, and also functions as a user interface that accepts user input via a touch panel function. In addition, the structure which receives the input from a user may be based on a mouse | mouth or a keyboard other than a touch panel function. In addition to the various data 331 to 334 provided for the execution of the feeder setup support program 500, the storage unit 330 stores a production program 262 that defines a procedure for mounting components on the board S in the component mounting apparatus 1. .

  The feeder setup support program 500 is for determining the type of feeder 141 to be set at the set position Ps. More specifically, the type of feeder 141 to be set at the set position Ps is determined based on the result of predicting the waiting time t when the mounting head 160 waits for the component to be supplied by the feeder when the component mounting process based on the production program 262 is executed. It is determined. Therefore, when executing the feeder setup support program 500, the arithmetic unit 310 accesses the production program 262 and determines the type of the component E to be supplied to the component supply position Pp in the component mounting process based on the production program 262. It confirms for every set position Ps (FIG. 5).

  FIG. 5 is a table showing the set positions and the types of components to be supplied to the component supply positions corresponding to the set positions. In the figure, in order to distinguish different set positions Ps, numerals in parentheses are attached to the reference signs Ps, and in order to distinguish different parts E, numerals in parentheses are attached to the reference signs E. A question mark in the feeder type T column indicates that the feeder type T is undecided at this time and is determined by the feeder setup support program 500.

  In addition, when executing the feeder setup support program 500, refer to the feeder number data 331 indicating the number of feeders 141 (the number of possessions) owned by the user and the number of feeders 141 that are currently used (the number of feeders used). (FIG. 6). FIG. 6 is a table showing feeder number data indicating the number of feeders held and the number of feeders used for each feeder type as a table. In the figure, in order to distinguish different feeder types T, numerals in parentheses are attached to the reference symbol T. When executing the feeder setup support program 500, the calculation unit 310 confirms whether the feeder number data 331 is stored in the storage unit 330. If the feeder number data 331 is not stored, the calculation unit 310 inputs the feeder number data 331. A display prompting the user is shown on the display 320.

  Further, when executing the feeder setup support program 500, the feeder capability data 332 indicating the capability (spec) of the feeder 141 is referred to (FIG. 7). FIG. 7 is a table showing feeder capability data indicating the capability of the feeder. As shown in FIG. 7, the width [mm] of the tape that can be fed by the feeder 141, the feed speed [mm / s] at which the feeder 141 feeds the part E, and the feed pitch [mm] at which the feeder 141 feeds the part E , And the component supply time [s] of the feeder 141 are shown for each feeder type T and stored as feeder capability data 332. In the figure, the notation “12/16” shown in the column of the sendable tape width indicates that the feeder 141 of the corresponding feeder type T (here, type T (7)) is a 12 mm wide tape and 16 It indicates that both [mm] width tapes can be sent out. When executing the feeder setup support program 500, the calculation unit 310 confirms whether the feeder capability data 332 is stored in the storage unit 330, and if not, inputs the feeder capability data 332. A display prompting the user is shown on the display 320.

  FIG. 8 is a flowchart showing the main routine of the feeder setup support program. FIG. 9 is a diagram schematically illustrating the handling of feeder types in the simulation executed according to the flowchart of FIG. As shown in FIG. 8, in step S100, standby time data generation for predicting the standby time t of the mounting head 160 that occurs when the component mounting process based on the production program 262 is executed is set for each set position Ps. In step S200, based on the standby time t predicted in step S100, feeder type assignment for determining the type T of the feeder 141 to be mounted at each set position Ps is executed. In step S300, the type T of the feeder 141 assigned in step S200 is displayed on the display 320, and a setup instruction for instructing the content of the feeder setup work to the user is executed. Subsequently, details of each of steps S100, S200, and S300 will be described.

  FIG. 10 is a flowchart showing details of standby time data generation executed in the flow of FIG. In step S110, the content of the standby time data 333 that stores the standby time t of the mounting head 160 for each set position Ps is cleared (reset). In step S <b> 120, the calculation unit 310 reads the production program 262 from the storage unit 330. Then, the calculation unit 310 executes steps S130 to S170, so that when the component suction at the component supply position Pp is executed according to the procedure specified in the production program 262, the waiting time t of the mounting head 160 is determined. Simulate how much it occurs. Specifically, the flow for reading out the part supply position Pp for next picking up the part from the production program 262 in step S130 and executing steps S140 to S160 for this part supply position Pp is all defined in the production program 262. This is repeated until the mounting of the parts is completed (step S170).

  Note that the flow in FIG. 10 is executed under a provisional condition that a feeder 141 of a specific feeder type Ti is attached to the set position Ps corresponding to the target component supply position Pp. This will be described with reference to FIG. 9. One specific feeder type Ti is selected from a plurality of feeder types T capable of supplying components to the target component supply position Pp, and this specific feeder type is selected. The flow of FIG. 10 is executed under a provisional condition that Ti is mounted at the target component supply position Pp. Incidentally, in this embodiment, among the feeder types T that can supply the part E specified by the production program to the target part supply position Pp, the feeder type Ts (latest feeder type) having the longest part supply time. A provisional condition is set that the feeder 141 is mounted as a feeder 141 of a specific feeder type Ti. In short, in the flow of FIG. 10, the waiting time t (worst case waiting time) of the mounting head 160 that occurs when the components are supplied with the feeder type Ts having the latest component supply time among the feeder types T that can supply the components. t) is predicted. However, the specific feeder type Ti temporarily assumed to be attached to the component supply position Pp is not limited to the latest feeder type Ts exemplified here, and a feeder capable of supplying components to the component supply position Pp. Any type T may be used.

  In step S140, the component delivery completion time is predicted (FIG. 11). FIG. 11 is a flowchart showing details of the prediction of the component delivery completion time executed in the flow of FIG. In step S141, it is determined whether or not the feeder 141 can start the delivery of the component to the target component supply position Pp. Specifically, when the component is removed from the component supply position Pp by the mounting head 160 and the component supply position Pp becomes empty, it is determined in step S114 that transmission can be started (YES).

  In step S142, as described above, among the feeder types T that can supply the component E specified by the production program to the target component supply position Pp, the feeder type Ts (latest feeder type) that has the longest component supply time. It is determined that the feeder 141 is provisionally mounted. More specifically, referring to FIG. 7, when the width of the tape for storing the component to be supplied to the target component supply position Pp is 8 [mm], three feeder types T (1), T (2), T (3) can supply components to the component supply position Pp. Therefore, in step S142, the feeder 141 of the feeder type T (3) having the longest component supply time among these is set to the set position Ps corresponding to the component supply position Pp to be used as the feeder 141 of the latest feeder type Ts. Assume that it is installed.

  In step S143, the time (component delivery completion time) at which the feeder 141 of the latest feeder type Ts determined in step S142 finishes sending the component to the target component supply position Pp is obtained. Specifically, the component supply start time (0.3 [s] in the example using FIG. 7) of the feeder 141 is added to the time when the feeder 141 starts sending the component, and the component delivery completion time is obtained. It is done.

  In step S144, by using the feeder 141 of the feeder type T having the shortest component supply time among the feeder types T that can supply the component E specified by the production program to the target component supply position Pp, the component delivery is completed. Time that can be moved forward (improveable transmission time) is required. As a result, among the feeder types T that can supply the part E defined by the production program to the target part supply position Pp, the longest part supply time (latest part supply time) to the shortest part supply time (fastest part supply) Subtracting (time), the transmission time that can be improved is obtained.

  Thus, when the flow of FIG. 11 is completed, the flow returns to the flow of FIG. 10, and the head movement completion time is predicted in step S150 (FIG. 12). FIG. 12 is a flowchart showing details of the head movement completion time prediction executed in the flow of FIG. In the flow of FIG. 12, the mounting head 160 that sucks the component supplied to the component supply position at the component supply completion time obtained in FIG. 11 (that is, the component supply completion time by the latest feeder type Ts) is the component supply position. Time for completing the movement to the head (head movement completion time) is obtained. Specifically, in step S151, the XY movement time required for the mounting head 160 to move in the XY plane and move above the component supply position is calculated. In step S152, the X movement time required for the mounting head 160 to descend from above the component supply position to the component supply position is calculated. In step S153, the head movement completion time is obtained by adding the XY movement time and the Z movement time to the time when the mounting head 160 starts moving (head movement start time).

  Thus, when the flow of FIG. 12 is completed, the flow returns to the flow of FIG. By completing Steps S140 and S150, the component 141 is completed when the latest feeder type Ts feeder 141 completes the delivery of the component to the target component supply position Pp, and the mounting head 160 that adsorbs the component. The head movement completion time for completing the movement to the component supply position was obtained. In step S160, the waiting time t of the mounting head 160 is predicted based on these times (FIG. 13).

  FIG. 13 is a flowchart showing details of the standby time prediction executed in the flow of FIG. In step S161, it is determined whether the head movement completion time is later than the feeder transmission completion time. If it is determined late (YES) in step S161, the feeder 141 completes the component supply to the component supply position before the head movement completion time when the mounting head 160 completes the movement to the component supply position. Therefore, it is determined that the waiting time t of the mounting head 160 does not occur, and the flowchart of FIG. 13 ends. If it is determined early (NO) in step S161, the feeder 141 has not completed the component supply to the component supply position at the head movement completion time when the mounting head 160 completes the movement to the component supply position. Therefore, it is determined that the waiting time t of the mounting head 160 occurs, and steps S162 to S167 are subsequently executed.

  In step S162, the current waiting time t is obtained by subtracting the head movement completion time from the feeder transmission completion time. In subsequent steps S163 to S167, the standby time data 33 is updated. Here, the contents of the standby time data will be described with reference to FIG. FIG. 14 is a table showing the contents of the standby time data as a table. As shown in FIG. 14, in the standby time data, standby time t predicted to occur when the component mounting process based on the production program 262 is executed is managed for each set position Ps. Specifically, with respect to the standby time t predicted to occur at the set position Ps from the calculation so far, the cumulative standby time [s] obtained by accumulating the standby time t and the maximum standby time that is the maximum value of the standby time t. Time tMax [s] is obtained and stored as standby time data. Therefore, in steps S163 to S167, the accumulated standby time and the maximum standby time tMax are updated.

  In step S163, the calculation unit 310 reads the standby time data 333. In step S164, the current standby time t obtained in S162 is added to the cumulative standby time stored in the standby time data 333 to update the cumulative standby time. In step S165, it is determined whether or not the current standby time t obtained in step S162 is longer than the maximum standby time tMax stored in the standby time data 333. If the current standby time t is longer than the maximum standby time tMax (“YES” in step S165), the maximum standby time tMax of the standby time data 333 is updated to the current standby time t, and step S167 is performed. Proceed to On the other hand, if the current standby time t is less than or equal to the maximum standby time tMax (“NO” in step S165), the process proceeds to step S167 without updating the maximum standby time tMax of the standby time data 333. In step S167, writing of the contents of the accumulated standby time and the maximum standby time tMax to the standby time data 333 is confirmed.

  Thus, when the flow of FIG. 13 is completed, the flow returns to the flow of FIG. And the flow which performs step S140-S160 is repeated until the mounting of all the components prescribed | regulated to the production program 262 is completed (step S170). As a result, the waiting time t generated when the component mounting process defined in the production program 262 is executed under a provisional condition that the feeder 141 of the latest feeder type Ts is attached to each component supply position Pp. The accumulated standby time and the maximum standby time tMax are obtained for each set position Ps, and stored as standby time data 333 for each set position Ps. Thus, when the flow of FIG. 10 is completed, the flow returns to the flow of FIG. 8, and the feeder type assignment in step S200 is executed based on the results of the flowcharts executed so far.

  FIG. 15 is a flowchart showing details of feeder type assignment executed in the flow of FIG. In step S210, the set positions Ps are sorted in the descending order of the accumulated waiting time in the waiting time data 333 (FIG. 16). FIG. 16 is a diagram schematically showing how the set positions are sorted. The table on the left of FIG. 16 shows the contents of the waiting time data 333 before sorting, and the table on the right of FIG. 16 shows the waiting time after sorting. The contents of data 333 are shown. As a result of this sorting, the set position Ps having a long accumulated standby time is stored at the upper level of the accumulated time sort list (the table on the left in FIG. 16). Then, steps S220 to S260 for determining the feeder type of the feeder 141 attached to the target set position Ps while reading the set positions Ps in order from the top of the cumulative time sort list are executed for all the set positions Ps. (Step S270).

  In step S220, among the set positions Ps for which the feeder type of the feeder 141 to be mounted has not been determined, the highest set position Ps in the cumulative time sort list in FIG. 16 is read. In step S230, the temporary feeder list is cleared (reset). This temporary feeder list is a list indicating feeder types T (usable feeder types) that can supply components to be supplied at the target set position Ps in the component mounting process based on the production program 262. In step S240, usable feeder types T are extracted for the target set position Ps, and a temporary feeder list is created (FIG. 17).

  FIG. 17 is a diagram schematically illustrating an example of a temporary feeder list. In FIG. 17, the case where the width of the tape for storing the parts to be supplied at the target set position Ps is 8 [mm] is exemplified, and three feeder types T (1) are usable feeder types T. , T (2), T (3) are listed. In this temporary feeder list, in addition to the component supply time [s], the supply time difference ΔT [s] and the priority order are stored for each feeder type. The supply time difference ΔT indicates the difference in the component supply time between the feeder type Ts having the longest component supply time among the usable feeder types T and each feeder type. The feeder type T having a short component supply time is larger. Supply time difference ΔT. Further, the priority order indicates the order in which the assignment to the set position Ps is performed, and is determined in a later step S250.

  In step S250, the priority order of the usable feeder types T is determined (FIG. 18). FIG. 18 is a flowchart showing details of the usable feeder priority determination executed in the flow of FIG. In step S2501, the count is reset to zero. In step S2502, the feeder types T are sorted in the ascending order of the supply time difference ΔT in the temporary feeder list. As a result of this sorting, a time difference ascending sort list is generated in which the feeder type T having a shorter supply time difference ΔT is stored in the higher order. Then, while reading the feeder types T in order from the top of the time difference ascending sort list (step S2503), steps S2504 to S2506 for determining the priority of the target feeder type T are executed for all feeder types T in the list. (Step S2507).

  In step S2504, the count is incremented by one. In step S2505, it is determined whether or not the supply time difference ΔT of the target feeder type T is equal to or greater than the maximum waiting time tMax of the target set position Ps (the set position Ps read in S220). If the supply time difference ΔT is equal to or greater than the maximum standby time tMax (“YES” in step S2505), the feeder type T feeder 141 completely eliminates the maximum standby time tMax and sets the target set position. It is determined that the standby operation of the mounting head 160 with respect to Ps can be completely prevented, and the current count is set as a priority in step S2506. On the other hand, when the supply time difference ΔT is less than the maximum standby time tMax (“NO” in step S2505), the feeder type T feeder 141 cannot completely eliminate the maximum standby time tMax. It is determined that a standby operation of the mounting head 160 for the set position Ps occurs, and no priority is given. Then, steps S2504 to S2506 are repeated for all feeder types T in the list while reading the feeder types T in order from the top of the time difference ascending sort list.

  As a result, a feeder type Tf (high-speed feeder type) in which the supply time difference ΔT is equal to or greater than the maximum standby time tMax and does not cause the standby time t is selected from the plurality of feeder types T, and for this high-speed feeder type Tf, the supply time difference As ΔT is shorter, higher priority is given (FIG. 9). Therefore, when there are a plurality of high-speed feeder types Tf, the high-speed feeder type Tf having the longest component supply time is preferentially assigned to the set position Ps. That is, it is predicted that the high-speed feeder type Tf can completely prevent the waiting time t of the mounting head 160 from occurring. Therefore, the high-speed feeder type Tf having the longest component supply time among the plurality of high-speed feeder types Tf is preferentially assigned to the set position Ps so that the excessively high-performance feeder type T is not assigned to the set position Ps. I have to.

  In subsequent steps S2509 to S2514, since the supply time difference ΔT is less than the maximum standby time tMax, the subsequent priority is assigned to the feeder type T that has not been given priority in the flow of steps S2501 to S2507. In step S2509, the feeder types T are sorted in the descending order of the supply time difference ΔT in the temporary feeder list. By this sorting, a time difference descending sort list is generated in which the feeder type T having a longer supply time difference ΔT is stored in the higher order. Then, while reading the feeder types T in order from the top of the time difference descending sort list (step S2510), steps S2511 to S2513 for determining the priority order of the target feeder types T are executed for all feeder types T in the list. (Step S2514).

  In step S2511, the count is incremented by one. In step S 2512, it is determined whether or not the supply time difference ΔT of the target feeder type T is equal to or longer than the maximum standby time tMax of the target set position Ps (the set position Ps read in step S 220). If the supply time difference ΔT is less than the maximum standby time tMax (“NO” in step S2512), the feeder 141 of this feeder type T completes the standby operation of the mounting head 160 for the target set position Ps. In step S2513, the current count is set as the priority order. On the other hand, if the supply time difference ΔT is greater than or equal to the maximum standby time tMax (“YES” in step S2512), this feeder type T has already been prioritized in the flow of steps S2501 to S2507. Judgment and do not give priority. Then, steps S2511 to S2512 are repeated for all the feeder types T in the list while reading the feeder types T in order from the top of the time difference descending sort list.

  As a result, for feeder type Tl (low-speed feeder type) in which supply time difference ΔT is less than maximum standby time tMax and causes standby time t, higher priority is given to a longer supply time difference ΔT (FIG. 9). Therefore, when there are a plurality of low-speed feeder types Tl, the low-speed feeder type Tl having the shortest component supply time is preferentially assigned to the set position Ps. That is, it is predicted that the low-speed feeder type Tl cannot completely prevent the waiting time t of the mounting head 160 from occurring. Therefore, among the plurality of low-speed feeder types Tl, the low-speed feeder type Tl having the shortest component supply time is preferentially assigned to the set position Ps, and the waiting time t of the mounting head 160 is shortened as much as possible.

  Thus, when the flow of FIG. 18 is completed, the flow returns to the flow of FIG. 15 and the used feeder confirmation in step S260 is executed. FIG. 19 is a flowchart showing details of the used feeder determination executed in the flow of FIG. In step S261, feeder types T are sorted in the ascending order of priority in the temporary feeder list. By this sorting, a priority sort list is generated in which the feeder type T having a higher priority is stored higher.

  In step S262, the feeder type T is read from the top of the priority order sort list, and in step S263, the feeder number data 331 is read. Then, for the feeder type T, it is determined whether the number of owned is greater than the number of used, in other words, whether the usable remaining number indicating the number of feeders 141 for which the allocation (mounting) to the set position Ps is undetermined is 1 or more. The If the remaining usable number is zero (in the case of “NO” in step S264), the process returns to step S262, and the feeder type T of the next rank is read in the priority sort list, and step S263, S264 is re-executed. On the other hand, when the usable remaining number is 1 or more (in the case of “YES” in step S264), the process proceeds to step S265.

  In step S265, the number of feeders 141 used is incremented by 1. In step S266, the content of the feeder number data 331 is updated based on this result. As a result, the usable remaining number of the feeder 141 of the corresponding feeder type T is decremented by one. In step S267, it is determined (assigned) that the currently loaded feeder type T is to be attached to the set position Ps, and the content of the feeder type T being attached to the set position Ps is set as the setup instruction data. Write to 334.

  Thus, when the flow of FIG. 19 is completed, the flow returns to the flow of FIG. 15 and the loop of step S270 is executed. That is, steps S220 to S260 are executed for all the set positions Ps, and the feeder type T of the feeder 141 to be mounted at each set position Ps is determined and written in the setup instruction data 334. When the feeder type assignment in FIG. 15 is completed, the process returns to the flow in FIG. 8 and the setup instruction in step S300 is executed.

  FIG. 20 is a flowchart showing details of the setup instruction executed in the flow of FIG. In step S301, the production program 262 is read. In step S302, it is determined whether the feeder type T of the feeder 141 to be mounted is specified by the setup instruction data 334 for the target set position Ps. If the setup instruction data 334 is not designated (“NO” in step S302), the process proceeds to step S303. In this step S303, it is determined to display on the display 320 that all feeder types T capable of supplying the parts to be supplied at the target set position Ps can be mounted at the set position Ps. On the other hand, when the setup instruction data 334 is designated (“YES” in step S303), the process proceeds to step S304. In step S304, it is determined that the feeder type T designated by the setup instruction data 334 is displayed on the display 320 so as to be mounted at the set position Ps. Then, Steps S301 to S304 are executed for all the set positions Ps (Step S305), and the display 320 displays the feeder type T of the feeder 141 attached to each set position Ps.

  As described above, in the embodiment configured as described above, the component E that the feeder 141 sequentially supplies to the component supply position Pp is picked up by the mounting head 160 and transferred to the substrate S. In such a configuration, the waiting time t of the mounting head 160 occurs because the component supply of the feeder 141 is not in time for the acquisition timing at which the mounting head 160 takes the component at the component supply position Pp. However, in other words, if the feeder 141 can supply components according to the acquisition timing of the mounting head 160, the occurrence of the standby time t is suppressed. That is, as the type T of the feeder 141, it is sufficient if it can supply components according to the acquisition timing of the mounting head 160.

  Focusing on this point, in this embodiment, when the component mounting process for mounting the component on the substrate S is executed, the waiting time t for which the mounting head 160 waits for the component supply by the feeder 141 is predicted (step S100). . Then, the feeder 141 to be mounted to the component supply position Pp is determined based on the waiting time t from among the plurality of types T feeders 141 having different component supply times (step S200). Therefore, the type T feeder 141 that supplies components with an appropriate component supply time according to the expected waiting time t, in other words, the type T feeder 141 that supplies components according to the acquisition timing of the mounting head 160 is provided. It can be determined to be mounted on the component supply position Pp. As a result, the component T can be controlled so that the waiting time t of the mounting head 160 can be suppressed by attaching an appropriate type T feeder 141 to the component supply position Pp from among the plurality of type T feeders 141 having different component supply times. The setup work of the user who mounts the feeder 141 on the mounting apparatus 1 can be supported (step S300).

  In this embodiment, the feeder 141 belonging to one specific type Ti (type Ts with the longest component supply time) of the plurality of types T is mounted on the component supply position Pp (step S142). ), A standby time t generated when the component mounting process is executed is predicted. Based on the difference in component supply time (supply time difference ΔT) between the types T other than the specific type Ti and the specific type Ti among the plurality of types T and the standby time t, the component T is mounted on the component supply position Pp. The feeder type T of the feeder 141 to be determined is determined (step S200). Thus, by predicting the standby time t generated when the component mounting process is executed under the condition where the feeder 141 is mounted on the component supply position, the standby time t can be predicted with relatively high accuracy. . However, if the standby time t is predicted for each of the feeders 141 of the plurality of types T, it may take a long time to complete the prediction of the standby time t. On the other hand, in this embodiment, the standby time t is predicted when the feeder 141 belonging to one specific type Ti (type Ts with the longest component supply time) of the plurality of types T is mounted. The time required to complete the prediction of time t can be suppressed. Further, the determination of the feeder type T is executed based on a difference in component supply time (a supply time difference ΔT) between a type T other than the specific type Ti among the plurality of types T and the specific type Ti and a waiting time t. For this reason, even if the standby time t is not predicted for all of the plurality of types T, the type T feeder 141 that supplies components at an appropriate component supply time corresponding to the standby time t is mounted on the component supply position Pp. Can be determined. In this way, it is possible to determine to attach an appropriate type T feeder 141 to the component supply position Pp while suppressing the time required to complete the prediction of the standby time t.

  In this embodiment, the maximum value of the waiting time t is obtained as the maximum waiting time tMax. When the high-speed type Tf feeder 141 is shorter than the specific type T feeder 141 by the maximum waiting time tMax or longer than the specific type T feeder 141, the high-speed type Tf feeder 141 is moved to the component supply position Pp. Is determined to be mounted (steps S2502 to S2507). Such a high-speed type Tf feeder 141 can supply components with a component supply time sufficiently quicker than the maximum waiting time tMax of the mounting head 160. Therefore, by determining that the high-speed type Tf feeder 141 is to be mounted on the component supply position Pp, the occurrence of the waiting time t of the mounting head 160 can be more reliably suppressed.

  In this embodiment, when there are a plurality of high-speed types Tf at the component supply position Pp, the feeder 141 of the high-speed type Tf having the longest component supply time among the plurality of high-speed types Tf is connected to the component supply position Pp. To be mounted (steps S2502 to S2507). That is, when there are a plurality of high-speed types Tf, all of the high-speed type Tf feeders 141 can supply components with sufficient timing to reliably suppress the occurrence of the waiting time t of the mounting head 160. Therefore, by determining that the high-speed type Tf having the longest component supply time is to be mounted among the high-speed type Tf feeders 141, it is possible to mount the feeder 141 having an appropriate capacity without excess or deficiency.

  Further, in this embodiment, when the high-speed type Tf does not exist for the component supply position, it is determined that the type T feeder 141 having the shortest component supply time among the plurality of types T is to be mounted on the component supply position Pp. (Steps S2509 to S2514). Thus, even when the high-speed type Tf feeder 141 as described above does not exist at the component supply position, the waiting time t of the mounting head 160 can be suppressed.

  In this embodiment, among the plurality of types T, the type Ts having the longest component supply time is set to the specific type Ti. Such a configuration is suitable for accurately predicting the estimated time of the mounting head 160.

  In this embodiment, the content of determining the feeder type T of the feeder 141 to be attached to the component supply position Pp is displayed on the display 320. In such a configuration, the user can appropriately perform the setup while confirming the display on the display 320, and the user's workability can be improved.

  Moreover, in this embodiment, the case where this invention was applied also to the component mounting apparatus 1 provided with the some component supply position Pp was illustrated. In other words, by performing the operation of predicting the standby time t and determining the feeder type T of the feeder 141 to be mounted based on the standby time t for each of the plurality of component supply positions Pp, It is possible to determine that a type T feeder 141 that supplies components in a certain component supply time is mounted at each component supply position Pp. As a result, it is possible to reduce the waiting time t of the mounting head 160 by mounting an appropriate type T feeder 141 among the plurality of type T feeders 141 having different component supply times to each component supply position. It is possible to support the setup work of the user who attaches the feeder 141 to the mounting apparatus 1.

  By the way, the number of feeders 141 owned by the user is limited. Therefore, in this embodiment, the feeder 141 to be mounted at each of the plurality of component supply positions Pp can be determined in consideration of such circumstances. Specifically, the number of feeders 141 that have not been determined to be mounted at the component supply position Pp (remaining usable number) is managed for each feeder type T (feeder number data 331). Each time the feeder type T of the feeder 141 to be mounted at the component supply position Pp is determined, the number of the corresponding feeders 141 is subtracted from the corresponding usable type T remaining number. The determination of the feeder type T of the feeder 141 to be mounted at the component supply position Pp has been executed based on the feeders 141 of a plurality of types T that are a combination of the types T whose remaining usable number is one or more. In such a configuration, it is possible to appropriately determine the feeders 141 to be mounted at each of the plurality of component supply positions Pp according to the number of feeders 141 held by the user.

  In this configuration, the type T of the feeder 141 to be mounted is determined in order for each component supply position Pp. Each time the feeder type T is determined, the remaining number of the feeder 141 is subtracted. For this reason, in the order of receiving the feeder type T, the component supply position Pp of the first board receives the determination of the feeder type T in a situation where the remaining number of the feeders 141 of each type T is large, so that the feeder having a relatively fast component supply time There is a tendency to decide to wear 141. On the contrary, in the order of receiving the feeder type T, the component supply position Pp in the final stage receives the determination of the feeder type when the number of remaining feeders 141 of each type T is small or zero. There is a tendency to install a slow feeder 141. That is, there is a tendency that the earlier the order in which the component supply position Pp receives the determination of the feeder type, the faster the component supply time of the type T of the feeder 141 for which the attachment to the component supply position Pp is determined.

  On the other hand, in this embodiment, the accumulated standby time obtained by accumulating the standby time t generated when the component mounting process is executed is obtained for each component supply position Pp. Then, the feeder type T is determined with priority from the component supply position Pp having a long accumulated standby time. In such a configuration, the feeder type T is determined at an earlier stage as the component supply position Pp is expected to have a longer accumulated standby time, so that the attachment of the type T feeder 141 with a relatively short component supply time is determined. . Therefore, it is possible to quickly supply the components with the type T feeder 141 having a short component supply time, and effectively compress the accumulated standby time predicted to be long. As a result, the tact time of the component mounting apparatus 1 can be suppressed.

Others As described above, in the above embodiment, the host computer 300 corresponds to an example of the “feeder setup support device” of the present invention, and the feeder setup support program 500 is an example of the “feeder setup support program” of the present invention. The recording medium 400 corresponds to an example of the “recording medium” of the present invention, and the calculation unit 310 and the storage unit 330 cooperate to “standby time prediction unit”, “feeder determination unit”, “remaining number” of the present invention. The display 320 functions as an example of the “management unit”, the display 320 corresponds to an example of the “display unit” of the present invention, and the feeder type assignment in step S200 corresponds to an example of the “feeder determination process” of the present invention.

  Here, the relationship between the standby time prediction unit, the feeder determination unit, the remaining number management unit, the calculation unit 310 and the storage unit 330 described in the above embodiment will be described with reference to FIG. Here, FIG. 21 is a block diagram schematically showing a standby time prediction unit, a feeder determination unit, and a remaining number management unit in the electrical configuration of FIG. As shown in the figure, the standby time prediction unit 300A, the feeder determination unit 300B, and the remaining number management unit 300C are realized in a form incorporated in a functional block including a calculation unit 310 and a storage unit 330.

  The standby time prediction unit 300A predicts a standby time t that the mounting head 160 waits for the component to be taken at the component supply position Pp to be supplied to the component supply position Pp by the feeder 141 when the component mounting process is executed. To do. Then, the feeder determination unit 330B determines a feeder type T of the feeder 141 to be mounted at the component supply position Pp from among the feeder types T that can supply the component to the component supply position Pp, based on the standby time t. Execute. As a result, the feeder 141 is sent to the component mounting apparatus 1 so that the waiting time t of the mounting head 160 can be suppressed by mounting an appropriate type T feeder 141 among the plurality of type T feeders 141 to the component supply position Pp. It is possible to assist the user who is wearing the setup work.

  Further, the remaining number management unit 300C manages the number of feeders 141 that are not yet determined to be mounted at the component supply position Pp as the usable remaining number for each type T. Then, each time the feeder determination process is executed, the remaining number management unit 300C subtracts the number of feeders 141 that have been determined to be mounted at the component supply position Pp by the feeder determination process from the available type T remaining number. To do. On the other hand, the feeder determination unit 300B sequentially executes feeder determination processing based on a plurality of types T feeders 141 that combine types T having one or more usable remaining numbers for each component supply position Pp. To do. As a result, according to the number of feeders 141 held by the user, it is possible to appropriately determine the feeders 141 to be mounted at each of the plurality of component supply positions Pp.

  The present invention is not limited to the above-described embodiment, and various modifications can be made to the above-described one without departing from the spirit of the present invention. Therefore, for example, the contents of steps S250 and S260 of the above embodiment can be modified as follows. That is, when all the feeder types T extracted for the target set position Ps in step S240 are the high-speed type Tf, the mounting head for the set position Ps is used regardless of the feeder 141 of any feeder type T. It is determined that the standby operation 160 can be completely prevented. Therefore, in such a case, it is determined that any feeder 141 of the feeder type T extracted in step S240 may be attached to the set position Ps (part supply position Pp), and this content is displayed on the display 320. May be displayed. In such a configuration, the trouble of preparing one type T feeder 141 at the time of setup can be saved, so that the burden on the user can be reduced.

  In the above embodiment, the standby time t is accumulated for the board that executes the component mounting process based on one production program 262. However, the period during which the standby time t is accumulated can be set as appropriate. In other words, there are cases where a plurality of production programs 262 showing different mounting procedures are executed in order to execute the component mounting process. Accordingly, the accumulated standby time may be obtained for the period in which the component mounting process is executed based on the plurality of production programs (FIG. 22).

  FIG. 22 is a flowchart illustrating a modification of the calculation mode of the accumulated standby time. In this flowchart, steps S402 to S404 are repeated by the number of production programs 262 (steps S401 and S405), and the accumulated standby time is obtained. Specifically, in step S <b> 402, standby time data is generated when a component mounting process is executed on one board S based on one production program 262. Thus, the accumulated standby time for one substrate S is obtained. In step S403, a product obtained by multiplying the accumulated standby time for one piece thus obtained by the number of substrates S to be produced in the target production program 262 is obtained again as the accumulated standby time. This cumulative standby time indicates the cumulative standby time t that occurs during the period in which the component mounting process is executed based on the target production program 262. In step S404, the total accumulated standby time obtained by adding the accumulated standby time already obtained for the other production program 262 is added to the total accumulated standby time newly obtained in step S403 to update the total accumulated standby time. To do. Such steps S402 to S404 are repeated by the number of production programs 262, and an accumulated standby time is obtained for a period in which component mounting processing based on a plurality of production programs is executed.

  Further, for example, as described in Japanese Patent Application Laid-Open No. 2009-272377, a component mounting system in which a plurality of component mounting apparatuses 1 are arranged in series and component mounting on the board S is performed in order by each component mounting apparatus 1. The present invention can also be applied to this (FIG. 23). FIG. 23 is a flowchart illustrating an example of a flow for determining the type of feeder to be mounted at the component supply position for a component mounting system including a plurality of component mounting apparatuses. In step S501, a cycle time is obtained for each of the plurality of component mounting apparatuses 1. In step S502, standby time data is generated for each set position Ps of each of the plurality of component mounting apparatuses 1. Then, in the standby time data, a cycle time sort list is created in which the arrangement order of the set positions Ps is sorted in descending order of the cycle times of the component mounting apparatus 1 to which the set position Ps belongs. As a result, the set position Ps having a longer cycle time of the component mounting apparatus 1 to which it belongs is stored in the higher rank of the cycle time sort list. As a result, steps S540 to S506 are executed in order from the top of the cycle time sort list, and the feeder type T is assigned in preference to the component mounting apparatus 1 having a long cycle time.

  In step S504, sorting is performed in the descending order of the accumulated standby time among the set positions Ps belonging to the target component mounting apparatus 1, and the set position Ps having a long accumulated standby time is stored at the top of the cycle time sort list. Will be. As a result, the feeder type T is assigned to the set position Ps belonging to the target component mounting apparatus 1 in preference to the set position Ps having a long accumulated standby time. In step S505, data necessary for assigning the feeder type is read for the target component mounting apparatus 1, and in step S200, the feeder type T is read for the target component mounting apparatus 1 in the same manner as described above. Allocation is performed. Then, steps S505 and S200 are executed for all the component mounting apparatuses 1 in order from the top of the cycle time sort list (step S506).

  That is, in the embodiment shown in FIG. 23, the feeder type T is determined in order from the component mounting apparatus 1 with a slow cycle time. In such a configuration, since the component mounting apparatus 1 having a longer cycle time receives the feeder type T determination at an earlier stage, the mounting of the type T feeder 141 having a relatively short component supply time is determined. Therefore, it is possible to quickly supply the components with the type T feeder 141 having a short component supply time, and to effectively compress the cycle time predicted to be long. As a result, the component mounting apparatus 1 predicted to have a longer cycle time is mounted with the type T feeder 141 having a shorter component supply time, and the cycle is performed between the plurality of component mounting apparatuses 1 constituting the component mounting system. Time can be leveled and throughput can be improved.

  Further, at the production site, the predetermined number of feeders 141 can be exchanged collectively using a cart that can set a predetermined number of feeders 141 and is detachable from the component mounting apparatus 1. Specifically, at a place for setup different from the component mounting apparatus 1 (or the component mounting system), a feeder 141 to be mounted next on the component mounting apparatus 1 is set on the carriage, and the component mounting apparatus 1 The feeder 141 to be attached to the component mounting apparatus 1 is exchanged by exchanging the cart attached to the component mounting apparatus 1 and the cart on which the feeder 141 to be installed next is set.

  Therefore, for example, when the contents of the substrate S produced in the morning and afternoon are partly changed, the feeder 141 can be efficiently replaced by executing a setup operation using a carriage. it can. However, in such a setup operation, the same feeder 141 cannot be shared among the carts to be exchanged. Therefore, the feeder type T is preferably assigned in consideration of this point. Therefore, when such a setup operation by the user occurs, the feeder 141 to be replaced in the setup operation is prohibited from being shared by the component mounting processes before and after the setup operation, and then set to the set position Ps. The type T of the feeder 141 to be attached may be determined. Specifically, in the same manner as described above, the waiting time data is generated by ticking before and after the setup work. However, the assignment of feeder type T is different from the above. According to the morning and afternoon examples, when assigning the feeder type T for the component mounting process in the morning, the number of feeder types T corresponding to the amount of the feeder 141 that is to be replaced and used in the afternoon is further increased. After subtraction, the assignment of feeder type T is executed. Also, the assignment of the feeder type T to the afternoon component mounting process is executed in the same manner.

  In such a configuration, the feeder 141 to be mounted on the component supply position Pp is determined so that the feeder 141 to be replaced in the setup operation is not shared by the component mounting process before and after the setup operation. If it demonstrates in said example, the feeder 141 used as replacement object by a setup operation will not be shared between the morning component mounting process and the afternoon component mounting process. Therefore, during execution of the morning component mounting process, the feeder 141 used in the afternoon component mounting process is set in advance in the feeder carriage, and when the afternoon component mounting process is completed, the feeder carriage is mounted on the component mounting apparatus 1. The component mounting process in the afternoon can be started immediately.

  The specific configuration of the feeder 141 is not limited to the tape feeder.

  In the above embodiment, the case where the feeder setup support device is provided as the host computer 300 separately from the component mounting apparatus 1 and the component mounting system has been described. However, the feeder setup support apparatus may be incorporated in the component mounting apparatus 1 or the like. In addition, a feeder setup support device may be built in a device having other functions used in a production site.
