Description

  The technology disclosed in this specification relates to a suction nozzle setup method for a surface mounting system and a surface mounting system.

Conventionally, a plurality of surface mounters having one or more types of detachable suction nozzles are arranged, and substrates are arranged in the order of the surface mounter on one end side to the surface mounter on the other end side in the arrangement direction of the plurality of surface mounters. A surface mounting system is known in which each surface mounting machine transports and mounts a component on the board using a suction nozzle.
By the way, in general, in the surface mounting system, the type of suction nozzles used for mounting differs depending on the type of substrate, so when the type of substrate is switched, some (or all) types of suction nozzles may be insufficient. In addition, since the type of suction nozzle used for mounting varies depending on the surface mounter, the type of suction nozzle that is insufficient also varies depending on the surface mounter.

  For this reason, in general, in a surface mounting system, when the type of a board is switched, the suction nozzle of the type that the surface mounting machine lacks in each surface mounting machine (that is, the surface mounting machine mounts a component on the next type of board) A so-called suction nozzle that supplies a suction nozzle of a type that the surface mounter does not have among the types of suction nozzles that are used in the process is used (for example, see Patent Document 1).

  Specifically, in the component replacement method described in Patent Document 1, in a counter circuit board work machine row including a plurality of counter circuit board work machines, a nozzle transport plate is connected from one end side of the circuit board work machine row. Setup is performed by conveying in the direction. More specifically, in the component element replacement method, the nozzle transport plate is transported from one end side, and each counter circuit board working machine to which the nozzle transport plate has been transported is left in the counter circuit board work machine. The nozzle is returned to the nozzle conveyance plate, and the missing kind of suction nozzle is acquired from the nozzle conveyance plate. Thereby, the suction nozzle remaining in the counter circuit board working machine on one end side is transferred to the counter circuit board working machine on the other end side.

  However, since the component replacement method is to transport the nozzle transport plate in one direction, the type of suction nozzle that is lacking in the counter circuit board working machine on the one end side is used in the counter circuit board working machine on the other end side. Even if it is left, it cannot be transferred to the counter circuit board working machine on one end side. For this reason, in the component replacement method, the operator holds the suction nozzle of a type that cannot be delivered from another counter circuit board working machine on the nozzle transport plate in advance.

  However, in general, the work of holding the suction nozzle on the nozzle transport plate is a troublesome and time-consuming work, which is a burden on the operator. In addition, there is a problem that an operation mistake such as a wrong type is likely to occur. For this reason, the method of reducing a worker's burden and work mistake is desired.

  The present specification discloses a technique for reducing the burden on the operator and work mistakes when setting up the suction nozzle of the surface mount system.

  In the surface mounting system suction nozzle setup method disclosed in the present specification, a plurality of surface mounting machines having one or more types of detachable suction nozzles are arranged, and the one end side of the plurality of surface mounting machines in the arrangement direction is arranged. It is a suction nozzle setup method for a surface mounting system in which a substrate is transported in the order of the surface mounting machine on the other end side from the surface mounting machine, and each of the surface mounting machines mounts a component on the substrate using the suction nozzle, One type that is lacking in one surface mounter by transporting the nozzle tray in which the suction nozzle is stored from the one end side to the other end side and from the other end side to the one end side A transfer step of transferring the suction nozzle from the other surface mounter having the extra type of the suction nozzle to the one surface mounter via the nozzle tray.

  According to the above suction nozzle setup method, the nozzle tray is transported bi-directionally to deliver the suction nozzle, so that the operator does not need to store the missing types of suction nozzles in the nozzle tray, or Even if it is necessary, the number of suction nozzles to be stored can be reduced as compared with the conventional case in which delivery is performed only in one direction. For this reason, it is possible to reduce the burden on the operator and work mistakes when setting up the suction nozzle of the surface mounting system.

  In addition, each surface mounting machine has the surface mounting based on the production information in which the type of the suction nozzle used for mounting the component is set and the type of the suction nozzle that the surface mounting machine has. A first determination step of determining the type of the suction nozzle remaining in the machine and the type of the suction nozzle that is insufficient may be included.

  According to the above suction nozzle setup method, compared to the case where the operator determines the types of suction nozzles that are surplus or insufficient for each surface mounter and sets them for each surface mounter, Can be further reduced.

  Further, when any one of the one end side and the other end side is defined as an upstream side and the other is defined as a downstream side, the delivery step is performed from the surface mounting machine on the upstream side to the surface mounting machine on the downstream side. The nozzle trays are transported in order, and each of the surface mounting machines to which the nozzle trays have been transported stores the suction nozzles remaining in the surface mounting machine in the nozzle tray, and the surface mounting machines are insufficient. When the suction nozzle of a certain type is acquired from the nozzle tray, and the suction nozzle of the type that is insufficient in the surface mounter that the nozzle tray has been transported is not stored in the nozzle tray A notification step of notifying the surface mounter that the surface mounter is in the downstream side of the surface mounter, and the notifying type.

  Further, in the reverse conveying step, when all of the notified types of the suction nozzles are stored in the nozzle tray, the nozzle tray may be reversely conveyed upstream.

  According to the above suction nozzle setup method, for example, when a plurality of types are notified as missing types, compared to when the nozzle tray is reversely transported every time some types of suction nozzles are stored in the nozzle tray The number of times the nozzle tray is reversely conveyed can be reduced. Thereby, it can set up efficiently.

  Further, when two or more of the surface mounting machines notify the surface mounting machine on the downstream side of the surface mounting machine, respectively, the two or more surfaces in the reverse conveying step. When all the suction nozzles of the type notified from the surface mounting machine on the most upstream side among the mounting machines are stored in the nozzle tray, the nozzle tray may be reversely conveyed to the upstream side.

  According to the above suction nozzle setup method, the surface mounting machine on the upstream side can finish the setup earlier, so if the one end side and the upstream side described above match, mounting the component on the board You can start at an earlier point.

  Further, the surface mounting system has a control device that is communicably connected to each of the surface mounting machines, and the suction nozzle setup method includes a type of the suction nozzle that the control device uses for mounting the component. Based on the production information set for each surface mounter and the types of suction nozzles that each surface mounter has, the types of suction nozzles that are left over and the suction that is lacking A second determination step of determining the type of nozzle for each surface mounter may be included.

  According to the above suction nozzle setup method, the control device determines the types of suction nozzles that are surplus in each surface mounter and the types of suction nozzles that are lacking. Compared to when the operator determines them. Thus, the burden on the worker and work mistakes can be further reduced.

  In addition, based on the result determined by the control device in the second determination step, the type of the suction nozzle stored in the nozzle tray, the type of the suction nozzle acquired from the nozzle tray, and the nozzle tray A determination step of determining the transport procedure for each surface mounter, and in the delivery step, each surface mounter stores the suction nozzle of the type determined by the control device in the nozzle tray, The type of the suction nozzle determined by the control device may be acquired from the nozzle tray, and the nozzle tray may be transported to the one end side or the other end side according to a transport procedure determined by the control device.

  According to the suction nozzle setup method described above, the processing load of each surface mounter can be reduced by controlling the whole by the control device.

  Further, in the second determination step, the control device has a surplus based on a plurality of the production information corresponding to the type of the substrate and the type of the suction nozzle included in each surface mounter. The type of the suction nozzle and the type of the suction nozzle that is insufficient may be determined for each surface mounter.

  According to the above suction nozzle setup method, the setup of the suction nozzle can be completed once for a plurality of types of substrates. For this reason, the time required for the setup can be reduced as compared with the case where the setup is performed for each type of substrate, and the productivity of the surface mounting system can be improved.

  Moreover, you may include the alerting | reporting process of alert | reporting to the operator the kind of the said suction nozzle which is insufficient in the said whole surface mounting system before or after the said delivery process.

(1-4) Nozzle Tray Next, the nozzle tray 90 will be described with reference to FIG. The nozzle tray 90 is used for transferring the suction nozzles 57 between the surface mounters 2 in the suction nozzle setup method described later. The nozzle tray 90 includes a plate-like substrate 91 shown in FIG. 5A and a shutter 92 shown in FIG. In FIGS. 5A and 5B, the substrate 91 and the shutter 92 are shown separately for easy understanding, but actually the shutter 92 is provided so as to cover the upper side of the substrate 91. ing.

  The plate-like substrate 91 has a plurality of storage holes 93 arranged in a matrix. In the shutter 92, a plurality of elongated holes 94 having a shape in which a plurality of through holes formed at positions corresponding to the respective storage holes 93 are connected for each row are formed in parallel. The space between the adjacent through holes in the front-rear direction is narrower than the diameter of the through holes, whereby the shutter 92 has narrow portions 95 respectively formed between the adjacent through holes.

  Similarly to the nozzle station 60 described above, when the tip of the suction nozzle 57 is inserted into the storage hole 93, the flange portion 57A (see FIG. 3) contacts the substrate 91. In this state, when the shutter 92 is slid to the left by the nozzle tray driving unit 70 described above, the narrow width portion 95 of the shutter 92 is positioned above the flange portion 57A, and when the nozzle shaft 54 is raised in this state, the flange portion 57A is The suction nozzle 57 is removed by engaging with the narrow width portion 95 and stored in the nozzle tray 90.

  The nozzle tray driving unit 70 can adopt any configuration as long as the shutter 92 can be moved in the left-right direction. For example, the substrate 91 and the shutter 92 are connected by a coil spring, and the nozzle tray driving unit 70 urges the shutter 92 to one of the left and right directions against the elastic force of the coil spring, and then the urge is released. In this case, the shutter 92 may return to the other side by the elastic return force of the coil spring.

  Further, the configuration of the nozzle tray 90 described above is an example, and the nozzle tray 90 can be stored with the suction nozzle 57 removed from the nozzle shaft 54, or the stored suction nozzle 57 can be attached to the nozzle shaft 54. If it is a structure, it will not be restricted to the structure mentioned above.

(1-5) Suction nozzle setup method The suction nozzle setup method according to the present embodiment roughly includes the nozzle tray 90 in both directions from the upstream side to the downstream side of the surface mounting system 1 and from the downstream side to the upstream side. By carrying, the one type of suction nozzle 57 that is insufficient in one surface mounting machine 2 is transferred from the other surface mounting machine 2 in which the type of suction nozzle 57 is left through the nozzle tray 90 to the one surface mounting machine 2. It is performed by delivering to the machine 2 (an example of a delivery process).

  Specifically, as shown in FIG. 1, in this embodiment, an empty nozzle tray 90 in which the suction nozzle 57 is not stored is transported in the order from the upstream surface mounter 2 to the downstream surface mounter 2. Each surface mounter 2 to which the nozzle tray 90 has been transported stores the suction nozzles 57 remaining in the surface mounter 2 in the nozzle tray 90, and the type and number of suctions that the surface mounter 2 lacks. The nozzle 57 is acquired from the nozzle tray 90 and stored in the nozzle station 60.

  For example, it is assumed that the first surface mounting machine 2A has three more type A suction nozzles 57 and the second surface mounting machine 2B has two more type A suction nozzles 57. In this case, the first surface mounter 2A stores all the remaining suction nozzles 57 (that is, three type A suction nozzles 57) in the nozzle tray 90, and the second surface mounter 2B is insufficient. The type and number of suction nozzles 57 (that is, two suction nozzles 57 of type A) are acquired from the nozzle tray 90.

However, if the nozzle tray 90 is only transported in one direction as in the order from the upstream surface mounter 2 to the downstream surface mounter 2, the type that the upstream surface mounter 2 lacks. The number of suction nozzles 57 remaining in the downstream surface mounting machine 2 cannot be transferred to the upstream surface mounting machine 2.
Therefore, in the present embodiment, when the nozzle tray 90 has been transported to a certain surface mounter 2, the surface mounter 2 acquires the amount and type of suction nozzles 57 that are insufficient from the nozzle tray 90. However, if there are still the types and numbers of the suction nozzles 57 that are still insufficient, the downstream types and numbers are notified to all the surface mounters 2 downstream.

  The downstream surface mounter 2 stores the suction nozzles 57 remaining in the surface mounter 2 in the nozzle tray 90, and as a result, all the notified types and numbers of suction nozzles 57 are stored in the nozzle tray 90. In such a case, the surface mounter 2 reversely conveys the nozzle tray 90 upstream. Then, the surface mounter 2 that has notified the downstream surface mounter 2 of the type and number that are lacking, when the nozzle tray 90 is transported from the downstream side, The suction nozzle 57 is acquired.

  Hereinafter, an example of setup with notification will be described with reference to FIG. Here, a case will be described as an example where the downstream surface mounter 2 is notified of the types and number of the two or more surface mounters 2 that are insufficient. In this embodiment, when the downstream surface mounter 2 is notified of the type and number of the two or more surface mounters 2 that are insufficient, the surface mounter that is the most upstream of the two or more surface mounters 2 The nozzle tray 90 is not transported upstream until the suction nozzles 57 of the type and number notified from 2 are all stored in the nozzle tray 90.

  For example, suppose that the first surface mounting machine 2A lacks three type A suction nozzles 57 and the second surface mounting machine 2B lacks two type B suction nozzles 57. Further, it is assumed that there are two types B suction nozzles 57 in the third surface mounting machine 2C and three types A suction nozzles 57 in the fourth surface mounting machine 2D.

  In this case, the first surface mounting machine 2A notifies the downstream surface mounting machine 2 (the second to fourth surface mounting machines 2) that the number of type A suction nozzles 57 is insufficient, and the nozzle tray 90 Is transported to the downstream surface mounting machine 2 (that is, the second surface mounting machine 2B).

  Then, the second surface mounter 2B notifies the downstream surface mounter 2 (3, 4th surface mounter 2) that the two type B suction nozzles 57 are insufficient, and the nozzle tray 90 is It is conveyed to the downstream surface mounting machine 2 (that is, the third surface mounting machine 2C).

  Then, the type B suction nozzles 57 are stored in the two-nozzle tray 90 by the third surface mounter 2C. As a result, the type and number of suction nozzles 57 notified from the second surface mounter 2B (that is, two suction nozzles 57 of type B) are all stored in the nozzle tray 90.

  However, the surface mounter 2 that is the most upstream among the surface mounters 2 (1st and 2nd surface mounters 2) that have notified the third surface mounter 2C of the type and number that are lacking (ie, the first surface mounter 2) Since the type and number of suction nozzles 57 notified from the surface mounter 2A) (that is, three types A of suction nozzles 57) are not yet stored in the nozzle tray 90, the third surface mounter 2C is the nozzle tray. 90 is conveyed not to the upstream side but to the surface mounting machine 2 on the downstream side (that is, the fourth surface mounting machine 2D).

  The fourth surface mounter 2 stores three type A suction nozzles 57 in the nozzle tray 90. In this case, the surface mounter 2 that is the most upstream among the surface mounters 2 (the first and second surface mounters 2) that have notified the fourth surface mounter 2D of the type and number that are lacking (ie, 1). Since the type and number of suction nozzles 57 notified from the second surface mounting machine 2A) (that is, three suction nozzles 57 of type A) are all stored in the nozzle tray 90, the fourth surface mounting machine 2D The nozzle tray 90 is reversely conveyed to the upstream surface mounting machine 2 (that is, the third surface mounting machine 2C).

  When the nozzle tray 90 is transported from the fourth surface mounter 2D, the third surface mounter 2C is the surface mounter 2 that has notified the third surface mounter 2 of the type and number that are lacking. Since all the types and numbers of suction nozzles 57 notified from the most upstream surface mounting machine 2 (that is, the first surface mounting machine 2A) are stored in the nozzle tray 90, the nozzle tray 90 is placed on the upstream surface. The sheet is conveyed back to the mounting machine 2 (that is, the second surface mounting machine 2B).

  When the second surface mounter 2B receives the nozzle tray 90 from the third surface mounter 2C, the number and types of suction nozzles 57 that are insufficient in the second surface mounter 2B (that is, the type B) Since the two suction nozzles 57 are stored in the nozzle tray 90, the lacking types and number of suction nozzles 57 are acquired from the nozzle tray 90. Then, the second surface mounter 2 cancels the notification that has been notified to the downstream surface mounter 2.

  Then, the second surface mounting machine 2 is the most upstream surface mounting machine 2 (ie, the first surface mounting machine) among the surface mounting machines 2 that has notified the second surface mounting machine 2 of the type and number that are lacking. Since the suction nozzles 57 of the kind and number notified from the machine 2A) are stored in the nozzle tray 90, the nozzle tray 90 is reversely transported to the upstream surface mounting machine 2 (that is, the first surface mounting machine 2A). .

  When the nozzle tray 90 is transported from the second surface mounter 2B, the first surface mounter 2A receives the lacking types and number of suction nozzles 57 (that is, the type A suction nozzles 57 are 3). Book) is obtained from the nozzle tray 90. Then, the first surface mounter 2A cancels the notification notified to the downstream surface mounter 2, and conveys the nozzle tray 90 to the downstream surface mounter 2 (that is, the second surface mounter 2).

(1-5-1) Processing of Control Unit Next, processing executed by the control unit 80 of each surface mounter 2 in order to realize the suction nozzle setup method described above will be described. In the suction nozzle setup method according to the present embodiment, when the type of the printed board P is switched, first, the operator switches the production program of each surface mounter 2 to a production program corresponding to the new type of the printed board P, The surface mounter 2 is instructed to set up the suction nozzle 57.
The controller 80 of each surface mounter 2 shifts to a standby state waiting for the nozzle tray 90 to be transported when the setup is instructed, and when the nozzle tray 90 is transported, the “nozzle tray “Process when transported” is executed.

Here, the nozzle tray 90 is set by the operator on the most upstream surface mounter 2, and the most upstream surface mounter 2 determines that the nozzle tray 90 has been conveyed when the nozzle tray 90 is set by the operator. It shall be. Further, when the operator sets the nozzle tray 90 on the most upstream surface mounter 2, it is assumed that an empty nozzle tray 90 in which the suction nozzle 57 is not stored is set.
Further, here, it is assumed that the suction nozzle 57 is not attached to any of the nozzle shafts 54 when performing the setup, and all the suction nozzles 57 included in each surface mounter 2 are stored in the nozzle station 60. .

(1-5-2) Processing when the nozzle tray is transported Hereinafter, processing when the nozzle tray is transported will be described with reference to FIG. The processing described below is executed in common when the nozzle tray 90 is conveyed from either the upstream side or the downstream side.

In S101, the control unit 80 compares the production program and the nozzle station information, and the types and number of suction nozzles 57 remaining in the surface mounter 2 provided with the control unit 80 are insufficient. The type and number of suction nozzles 57 are determined (an example of a first determination step). Then, the control unit 80 proceeds to S <b> 102 if there is a surplus suction nozzle 57 or a short suction nozzle 57, and proceeds to S <b> 105 if there is no suction nozzle 57.
In S102, the control unit 80 stops the nozzle tray 90 at the work position B, and fixes the nozzle tray 90 by the clamp unit.

  In S <b> 103, when there are surplus suction nozzles 57, the control unit 80 stores all the surplus suction nozzles 57 in the nozzle tray 90. Then, the control unit 80 updates the nozzle station information according to the type and number of suction nozzles 57 stored in the nozzle tray 90 from the nozzle station 60.

  In S <b> 104, the control unit 80 recognizes the type and number of suction nozzles 57 stored in the nozzle tray 90 by the substrate recognition camera C <b> 1, and acquires the insufficient types and number of suction nozzles 57 from the nozzle tray 90. Store in a vacant storage hole in the nozzle station 60. However, since the nozzle tray 90 may not store the types and number of suction nozzles 57 that are insufficient in the surface mounter 2, in this case, only the amount that can be acquired is acquired. Then, the control unit 80 updates the nozzle station information according to the type and number of the suction nozzles 57 stored in the nozzle station 60.

In S105, the control unit 80 determines whether or not the type and number that are lacking are notified from the upstream surface mounter 2, and proceeds to S106 if notified, or to S108 if not notified. move on.
In S <b> 106, the control unit 80 notifies all the types and numbers of suction nozzles 57 notified from the most upstream surface mounter 2 among the surface mounters 2 that have notified the surface mounter 2 of the types and numbers that are insufficient. It is determined whether or not it is stored in the tray 90. If it is stored, the process proceeds to S107, and if it is not stored, the process proceeds to S108.

In S107, the control unit 80 reversely conveys the nozzle tray 90 to the upstream surface mounter 2 (an example of a reverse conveyance step).
In S <b> 108, the control unit 80 executes a downstream transport process for transporting the nozzle tray 90 to the downstream side.

(1-5-3) Downstream Transport Processing Next, the downstream transport processing executed in S108 will be described with reference to FIG.

In S201, the control unit 80 determines whether or not there is the surface mounter 2 on the downstream side of the surface mounter 2, and if so, the process proceeds to S202, and if not, the process proceeds to S206.
In S202, the control unit 80 determines whether there is a suction nozzle 57 that is still insufficient in the surface mounter 2, and if there is, the process proceeds to S203, and if not, the process proceeds to S204.
In S <b> 203, the control unit 80 notifies all the surface mounters 2 on the downstream side of the surface mounter 2 of the type and number that are lacking in the surface mounter 2 (an example of a notification process).

In S <b> 204, if the control unit 80 has notified the downstream type surface mounter 2 of the type and number that are lacking, the notification is cancelled. For example, if the nozzle tray 90 has been conveyed from the downstream side when the downstream type surface mounter 2 has been notified to the downstream type surface mounter 2, the type and number that are insufficient in step S104 described above. Since all the suction nozzles 57 are acquired, the previous notification is canceled by this step.
In S205, the control unit 80 conveys the nozzle tray 90 to the surface mounter 2 on the downstream side.

  In S206, the control unit 80 (that is, the control unit 80 of the most downstream surface mounter 2) determines whether there is a suction nozzle 57 that is insufficient in the entire system. Specifically, for example, the control unit 80 has a suction nozzle 57 that is still insufficient in the surface mounter 2 or a notification that has not yet been canceled among the notifications notified from the upstream surface mounter 2. If there is a suction nozzle 57 that is insufficient in the entire system, it is determined that there is no suction nozzle 57 that is insufficient in the entire system. If there is a suction nozzle 57 that is insufficient in the entire system, the control unit 80 proceeds to S207, and if not, ends the present process and returns.

  In S207, the control unit 80 displays on the display unit 81 the type and number of suction nozzles 57 that are insufficient in the entire system (an example of a notification process). Then, the operator manually stores the displayed types and number of suction nozzles 57 in the nozzle tray 90 and instructs the setup of the suction nozzles 57 again.

(1-6) Effect of Embodiment According to the suction nozzle setup method according to the first embodiment described above, the nozzle tray 90 is transported in both directions from the upstream side to the downstream side, and from the downstream side to the upstream side, and the suction nozzle. Therefore, when the surface mounting system 1 is first instructed to set up, the operator does not need to store the lacking types and number of suction nozzles 57 in the nozzle tray 90. For this reason, it is possible to reduce the burden on the operator and work mistakes when setting up the suction nozzle 57 of the surface mounting system 1.
However, when there is a suction nozzle 57 that is insufficient in the entire system, the operator needs to store the lacking suction nozzle 57 in the nozzle tray 90. However, even in that case, in the suction nozzle setup method according to the first embodiment, the suction nozzle 57 is transferred in both directions, so that the suction nozzle is stored as compared with the case where the suction nozzle 57 is transferred only in one direction as in the prior art. The number of is small. For this reason, even in that case, the burden on the operator and work mistakes can be reduced.

  Furthermore, according to the suction nozzle setup method according to the first embodiment, each surface mounting machine 2 is configured so that the types and number of suction nozzles 57 remaining in the surface mounting machine 2 as well as the types of suction nozzles 57 that are insufficient and Since the number is determined, it is possible to further reduce the burden on the operator and work errors compared to the case where the operator determines them and sets them in each surface mounter 2.

  Furthermore, according to the suction nozzle setup method according to the first embodiment, since a plurality of surface mounters 2 operate in cooperation, a control device that controls the plurality of surface mounters 2 becomes unnecessary, and the configuration of the surface mount system 1 is simplified. Can be.

  Furthermore, according to the suction nozzle setup method according to the first embodiment, the surface mounter 2 notified of the lacking type and number has all of the notified type and number of suction nozzles 57 stored in the nozzle tray 90. In this case, the nozzle tray 90 is reversely conveyed upstream (one end side). For this reason, for example, when a plurality of types of suction nozzles 57 are notified as missing types, each time the nozzle tray 90 is reversely conveyed each time the suction nozzles 57 are stored in the nozzle tray 90. In comparison, the number of times the nozzle tray 90 is reversely conveyed can be reduced. Thereby, it can set up efficiently.

  Further, according to the suction nozzle setup method according to the first embodiment, when two or more surface mounters 2 notify the surface mounter 2 on the downstream side of the surface mounter 2 that the type and number are insufficient. The surface mounter 2 notified of the lacking type and number is the suction nozzle of the type and number notified from the most upstream (most end side) surface mounter 2 of the two or more surface mounters 2 When all 57 are stored in the nozzle tray 90, the nozzle tray 90 is reversely conveyed upstream (one end side). In this way, the surface mounting machine 2 on the upstream side can finish the setup earlier, so that the mounting of the electronic component E on the printed circuit board P can be started at an earlier time.

  Furthermore, according to the suction nozzle setup method according to the first embodiment, after the delivery process, the type and number of suction nozzles 57 that are insufficient in the entire system are displayed on the display unit 81, so that the operator By manually storing a number of suction nozzles 57 in the nozzle tray 90 and instructing the setup of the suction nozzles 57 again, any of the surface mounting machines 2 can be made free of the suction nozzles 57 that are lacking. .

Thereafter, the nozzle tray 90 is set to be conveyed to the second surface mounter 2B.

  The second surface mounter 2 is set so that when the nozzle tray 90 is first transported from the first surface mounter 2, the nozzle tray 90 is transported to the third surface mounter 2. . Then, when the nozzle tray 90 is subsequently conveyed from the third surface mounter 2, two type B suction nozzles 57 are acquired from the nozzle tray 90, and then the nozzle tray 90 is replaced with the first surface mounter. Set to transport to 2A. Then, when the nozzle tray 90 is transported from the first surface mounter 2A thereafter, the nozzle tray 90 is set to be transported to the third surface mounter 2C.

  When the nozzle tray 90 is first transported from the second surface mounter 2 to the third surface mounter 2, the type B suction nozzles 57 are stored in the two nozzle tray 90, and thereafter The nozzle tray 90 is set to be conveyed to the fourth surface mounter 2. Then, when the nozzle tray 90 is transported from the fourth surface mounter 2 thereafter, the nozzle tray 90 is set to be transported to the second surface mounter 2B. After that, when the nozzle tray 90 is transported from the second surface mounter 2, the nozzle tray 90 is set to be transported to the fourth surface mounter 2D.

  When the nozzle tray 90 is first transported from the third surface mounter 2 to the fourth surface mounter 2, the type A suction nozzles 57 are stored in the three nozzle tray 90, and the nozzle tray 90 90 is set to be conveyed to the third surface mounter 2. As a result, the operation of the surface mounting system 3 is the same as that described in the first embodiment.

  For example, in a certain surface mounting machine 2, it is assumed that one type A suction nozzle 57 is used in the next production program and two type A suction nozzles 57 are used in the next production program. Further, it is assumed that the surface mounter 2 does not have any type A suction nozzle 57. In this case, the control device 100 determines that two type A suction nozzles 57 are insufficient in the surface mounter 2 and sets to acquire two type A suction nozzles 57 from the nozzle tray 90.

  According to the suction nozzle setup method according to the third embodiment described above, the setup of the suction nozzle 57 can be completed once for a plurality of types of printed circuit boards P. Therefore, the setup is performed for each type of printed circuit board P. The time required for setup can be reduced as compared with FIG. Thereby, the productivity of the surface mounting system 3 can be improved.

  (2) In the above-described embodiment, when two or more surface mounters 2 are notified of the type and number that are insufficient, the surface mounter 2 that is notified of the type and number of the shortage are those two or more. When all the types and number of suction nozzles 57 notified from the most upstream (one end side) surface mounting machine 2 among the surface mounting machines 2 are stored in the nozzle tray 90, the nozzle tray 90 is reversely conveyed upstream. . On the other hand, when all the types and number of suction nozzles 57 notified from any of the surface mounting machines 2 are stored in the nozzle tray 90, it does not matter whether the surface mounting machine 2 is the most upstream side. The nozzle tray 90 may be transported upstream.

  (3) In the above embodiment, the case where the type and number of the suction nozzles 57 that are insufficient in the entire system are displayed on the display unit 81 after the delivery process has been described as an example. On the other hand, when the control device 100 is present as in the second embodiment, the type and number of suction nozzles 57 that are insufficient in the entire system are calculated in advance by the control device 100 and displayed on the display unit 81 before the delivery process. May be. In this way, when the operator stores the indicated type of suction nozzle 57 in the nozzle tray 90 and then instructs the setup, the suction nozzles in which any of the surface mounting machines 2 is insufficient in one setup. 57 can be eliminated.

The suction nozzle 57 may not be stored in the nozzle tray 90. In this way, when the downstream surface mounting machine 2 tries to acquire the suction nozzles 57 that are lacking from the nozzle tray 90, the upstream surface mounting machine 2 may have an extra suction nozzle 57 of that type. It is possible that the type of suction nozzle 57 is not stored in the nozzle tray 90. Therefore, in that case, the upstream surface mounter 2 may be notified of the type and number of suction nozzles 57 that the downstream surface mounter 2 is lacking, and the nozzle tray 90 may be transported upstream.

  (8) In the above embodiment, the case where the type and number of the suction nozzles 90 stored in the nozzle tray 90 are recognized by the component recognition camera C1 has been described as an example. On the other hand, when storing the remaining suction nozzles 57 in the nozzle tray 90, nozzle tray information indicating which type of suction nozzles 57 are stored in which storage holes 93 of the nozzle tray 90 is stored in the nozzle tray 90. While updating according to the type and number of the suction nozzles 57 stored, and acquiring the insufficient types and number of suction nozzles 57 from the nozzle tray 90, the nozzle tray information is updated according to the acquired type and number. You may do it. And when conveying the nozzle tray 90 to an upstream side or a downstream side, you may make it transmit nozzle tray information to the surface mounting machine 2 of an upstream side or a downstream side. In this way, the upstream and downstream surface mounting machines 2 do not require a step of recognizing the type and number of suction nozzles 90 stored in the nozzle tray 90 by the component recognition camera C1, so that the setup can be performed more efficiently. It can be carried out.

  (9) In the above-described embodiment, an example has been described in which the type of suction nozzle 57 stored in which storage hole 64 of the nozzle station 60 is set in the nozzle station information. On the other hand, instead of using the nozzle station information, the component recognition camera C1 may recognize which type of suction nozzle 57 is stored in which storage hole 64 of the nozzle station 60. Alternatively, when the nozzle tray 90 is first transported, the component recognition camera C1 recognizes the nozzle tray 90 only once, generates nozzle station information from the recognized information, and thereafter refers to and updates the nozzle station information. May be.

  (10) In the above embodiment, the case where the upstream side when the printed board P is transported and the upstream side when the transport of the nozzle tray 90 is the same side is described as an example. On the other hand, the upstream side when the printed board P is transported and the upstream side when the transport of the nozzle tray 90 is started may be reversed. Specifically, when the conveyance of the nozzle tray 90 is started, the conveyance of the nozzle tray 90 may be started from the downstream side (left side in FIG. 1) when the printed board P is conveyed. In this case, for the nozzle tray 90, the left side is the upstream side and the right side is the downstream side.
