  Hereinafter, as a mode for carrying out the present invention, an embodiment of the present invention will be described in detail with reference to the drawings.

<Configuration of board-to-board operation system>
1 and 2 show a substrate handling system 10. A system 10 shown in the figure is a system for mounting electronic components on a circuit board. The substrate-to-board operation system 10 includes two electronic component mounting machines (hereinafter, may be abbreviated as “mounting machines”) 12 and 14 and a feeder replacement device 16. The two mounting machines 12 and 14 are disposed adjacent to each other. In the following description, the direction in which the mounting machines 12 and 14 are arranged is referred to as the X axis direction, the horizontal direction perpendicular to the X axis direction is referred to as the Y axis direction, and the vertical direction perpendicular to the X axis direction is the Z axis direction. It is called.

  The two mounting machines 12 and 14 have substantially the same configuration. Each of the mounting machines 12 and 14 includes a transport device 20, a mounting head 22, a mounting head moving device (hereinafter, may be abbreviated as a "moving device") 24, and a supply device 26.

  The transfer device 20 includes two conveyor devices 30 and 32. The two conveyor devices 30 and 32 are disposed on the base 34 so as to extend parallel to each other and in the X-axis direction. Each of the two conveyor devices 30 and 32 transports the circuit board supported by each of the conveyor devices 30 and 32 by an electromagnetic motor (see FIG. 6) in the X-axis direction. Each of the conveyors 30, 32 has a substrate holding device (see FIG. 6) 38, and holds the circuit board fixedly at a predetermined position.

  The mounting head 22 mounts an electronic component on a circuit board. Specifically, the mounting head 22 has a suction nozzle 60 provided on the lower end surface. The suction nozzle 60 communicates with a positive / negative pressure supply device (see FIG. 6) 62 through a negative pressure air and a positive pressure air passage. The suction nozzle 60 sucks and holds the electronic component by the negative pressure and separates the held electronic component by the positive pressure. Further, the mounting head 22 has a nozzle lifting device (see FIG. 6) 64 for moving the suction nozzle 60 up and down. The mounting head 22 changes the position of the electronic component to be held in the vertical direction by the nozzle lifting device 64. The suction nozzle 60 is detachably attached to the mounting head 22, and can be changed to suction nozzles of different sizes.

  The moving device 24 is a device for moving the mounting head 22 to an arbitrary position on the base 34. Specifically, the moving device 24 is configured of an X-axis direction sliding mechanism 70 and a Y-axis direction sliding mechanism 72. The Y-axis direction slide mechanism 72 has a pair of Y-axis direction guide rails 74, and the pair of Y-axis direction guide rails 74 are arranged to extend in the Y-axis direction. On the other hand, the X-axis direction slide mechanism 70 has an X-axis direction guide rail 76, and the X-axis direction guide rail 76 extends in the X-axis direction to the pair of Y-axis direction guide rails 74. It is held. The Y-axis direction slide mechanism 72 has an electromagnetic motor (see FIG. 6) 78, and the drive of the electromagnetic motor 78 moves the X-axis direction guide rail 76 to an arbitrary position in the Y-axis direction. The X-direction guide rail 76 holds the slider 80 movably along its own axis. The X-axis direction sliding mechanism 70 has an electromagnetic motor (see FIG. 6) 82, and the driving of the electromagnetic motor 82 moves the slider 80 to an arbitrary position in the X-axis direction. The mounting head 22 is mounted on the slider 80. With such a structure, the mounting head 22 is moved by the moving device 24 to any position on the base 34. In addition, since the slider 80 can move only to the range where the Y-axis direction guide rail 74 and the X-axis direction guide rail 76 are disposed, the moving device 24 moves to any position on the base 34 arbitrarily. It is not possible but can be arbitrarily moved within a predetermined range on the base 34. In addition, the mounting head 22 is attachable to and detachable from the slider 80 with one touch. Thus, it is possible to change to different types of working heads such as a dispenser head.

  The feeding device 26 is disposed at the front end of the base 34 and has a plurality of tape feeders 90. Each tape feeder 90 has a reel 92, a delivery device 94, and a peeling device 96, as shown in FIG. 3, and supplies electronic components at the end of the upper surface. Specifically, a taped component 98 is wound around the reel 92, and the taped component 98 is drawn from the reel 92 onto the tape guide 100. The taped component 98 is obtained by taping an electronic component, and feed holes (not shown) are formed at a predetermined pitch. The sprocket 102 of the delivery device 94 is engaged with the feed hole. Then, the sprocket 102 is rotated by the electromagnetic motor 104. With such a structure, the taped component 98 is delivered toward the supply position.

  Further, the peeling device 96 has a film peeling mechanism 106 and a gear mechanism 108. The film peeling mechanism 106 is a mechanism for peeling the top film 110 from the taped component 98, and is disposed in front of the opening 112 formed at the upper end of the tape feeder 90. The gear mechanism 108 is a mechanism for pulling the top film 110 peeled off from the taped component 98 into the film recovery unit 114. With such a structure, by peeling the top film 110 from the taped component 98, the electronic component accommodated in the taped component 98 is exposed at the opening 112, and the exposed electronic component is mounted on the mounting head 22. By the suction nozzle 60 of FIG. That is, the opening 112 is the electronic component supply position of the tape feeder 90. A tape guide passage 116 is formed on the side surface of the opening 112 in the delivery direction of the taped component 98 so as to be directed downward. Through the tape guide passage 116, the waste tape 118 from which the electronic component has been taken out of the taped component 98 is discharged.

  Further, as shown in FIGS. 1 and 2, the tape feeder 90 is detachably attachable to a tape feeder holder 120 fixedly provided at the front end of the base 34. As shown in FIG. 4, the tape feeder holder 120 is composed of an erected surface portion 122 erected in the vertical direction with respect to the base 34, and a projecting portion 124 projecting from the lower end of the erected surface portion 122. . The erected surface portion 122 is provided with a connector connection portion 126. On the other hand, a connector 128 is provided on the side surface of the tape feeder 90. Then, the connector 128 of the tape feeder 90 is connected to the connector connection portion 126 of the erected surface portion 122, whereby the bottom surface of the tape feeder 90 is supported by the projecting portion 124. Thus, the tape feeder 90 is mounted on the tape feeder holder 120. The tape feeder holder 120 is disposed within the range of movement of the mounting head 22 by the moving device 24. As a result, the electronic component can be held by the mounting head 22 from the tape feeder 90 mounted on the tape feeder holder 120.

  Further, not only the tape feeder 90 but also the cassette type nozzle accommodation unit 130 is detachably mounted on the tape feeder holding base 120. The cassette type nozzle accommodation unit 130 accommodates a plurality of types of suction nozzles 60 having different nozzle diameters and the like, and includes a nozzle station 132 and a circulating device 134 as shown in FIG. 5. The nozzle station 132 has a disk shape, and a plurality of accommodation portions (not shown) are formed on the outer peripheral portion at equal pitches. The accommodating portion accommodates the suction nozzle 60 and is configured to be switchable between a state in which the accommodated suction nozzle 60 is clamped and a state in which the clamp is released.

  The nozzle station 132 on the disk is disposed in the loading section 136 so that its axis extends horizontally, and is rotatable about the axis. An opening 138 is formed at the upper end of the loading unit 136 at the upper end surface of the cassette type nozzle accommodation unit 130, and the outer periphery of the nozzle station 132 is exposed from the opening 138. Further, the orbiting device 134 has a gear mechanism 140 and an electromagnetic motor 142, and the driving force of the electromagnetic motor 142 is transmitted to the nozzle station 132 via the gear mechanism 140. As a result, the nozzle station 132 revolves around the axial center, and the suction nozzle 60 housed in the housing portion moves to an arbitrary position. That is, the suction nozzle 60 can be supplied by moving the suction nozzle 60 housed in the housing portion to a position exposed from the opening 138. Further, by moving the storage portion in which the suction nozzle 60 is not stored to a position where the suction nozzle 60 is exposed from the opening portion 138, the suction nozzle 60 can be stored in the storage portion. The cassette type nozzle accommodation unit 130 is also provided with the same connector (not shown) as the connector 128 provided in the tape feeder 90, and the connector of the cassette type nozzle accommodation unit 130 is the same as that of the tape feeder holding stand 120. The cassette type nozzle accommodation unit 130 is attached to the tape feeder holder 120 by being connected to the connector connection portion 126.

The horizontal movement device 162 also has an X-axis direction guide rail 168, and the X-axis direction guide rail 168 is held by a pair of Z-axis direction guide rails 166 so as to extend in the X-axis direction. ing. Then, the X-axis direction guide rail 168 is moved to an arbitrary position in the Z-axis direction by the drive of the Z-axis direction motor (see FIG. 6) 170. Also, the X-direction guide rail 168 holds the clamp mechanism 164 so as to be movable along its axis. The clamp mechanism 164 is moved to an arbitrary position in the X-axis direction by driving the X-axis direction motor (see FIG. 6) 172. Further, the clamp mechanism 164 is expandable in the Y-axis direction, and is expanded or contracted in the Y-axis direction by the drive of an expansion motor (see FIG. 6) 174. In addition, a clamp unit (not shown) for clamping the tape feeder 90 or the cassette type nozzle accommodation unit 130 is provided at the tip of the clamp mechanism 164. With such a structure, as described in detail later, the exchange robot 154 is configured as a tape feeder 90 or a cassette type between each of the tape feeder holding base 120, the tape feeder receiving base 150, and the tape feeder receiving case 152.

Thus, the controller 182 acquires various information of the tape feeders 90 and the like accommodated in the respective slots of the tape feeder accommodation case 152.

<Installation work by board-to-board work system>
In the substrate-to-board operation system 10, the mounting operation of the electronic component on the circuit board is performed by the above-described configuration. Specifically, in response to a command from the controller 182, the circuit board is carried in by the transfer device 20 of the mounting machine 12 and transferred to the work position. Then, the circuit board is fixedly held by the board holding device 38 at the position. Further, the tape feeder 90 mounted on the tape feeder holding base 120 sends out the taped components and supplies the electronic components at the supply position according to the command of the controller 182. Then, the mounting head 22 moves to the upper side of the supply position of the electronic component by a command of the controller 182, and the suction nozzle 60 sucks and holds the electronic component. Subsequently, the mounting head 22 moves to the upper side of the circuit board according to a command from the controller 182, and mounts the held electronic component on the circuit board. When the mounting operation of the mounting machine 12 is completed, the circuit board is carried out of the mounting machine 12 and carried into the mounting machine 14 by a command of the controller 182. The mounting operation of the mounting machine 14 is performed in the same manner as the mounting machine 12. When the mounting operation of the mounting machine 14 is completed, the circuit board is unloaded from the mounting machine 14 according to a command from the controller 182. Thereby, a circuit board on which the electronic component is mounted is manufactured.

Specifically, the cassette-type nozzle accommodation unit 130 mounted on the tape feeder holder 120 rotates the nozzle station 132 according to a command from the controller 182, and the accommodation portion in which the suction nozzle 60 is not accommodated is an opening. Expose at 138. On the other hand, the mounting head 22 is moved above the opening 138 of the cassette type nozzle housing unit 130 by the command of the controller 182. Then, the mounting head 22 lowers the suction nozzle 60 mounted thereon and stores the suction nozzle 60 in the housing portion of the nozzle station 132. Next, in response to a command from the controller 182, the cassette type nozzle accommodation unit 130 circulates the nozzle station 132 to expose the accommodation portion in which the suction nozzle 60 is accommodated to the opening 138. Then, the mounting head 22 lowers the mounting portion (not shown) of the suction nozzle 60 according to a command from the controller 182, and mounts the suction nozzle 60 on the mounting portion. Thus, the suction nozzle 60 mounted on the mounting head 22 is replaced.

<Replacement of Tape Feeder etc. in Substrate-to-Board Operation System>
As described above, the mounting machines 12 and 14 suck and hold the electronic components supplied by the tape feeder 90 by the suction nozzle 60 of the mounting head 22 and mount the suction-held electronic components on the circuit board Is configured. In the mounting machines 12 and 14 configured as described above, it is possible to replace the tape feeder 90 mounted on the tape feeder holding base 120 with a new tape feeder 90 in order to cope with the shortage of electronic components and the like. ing.

  In the conventional mounting machine, the replacement work of the tape feeder 90 is performed by the operator, which is a time-consuming work. In view of this, in the substrate handling system 10, the tape feeder 90 can be replaced automatically. In the following, the operation of automatically replacing the tape feeder 90 in the substrate handling system 10 will be described in detail.

  When the number of electronic components accommodated in the tape feeder 90 becomes equal to or less than a predetermined number, the tape feeder (hereinafter sometimes referred to as “used feeder 90 a”) is replaced from the tape feeder holding stand 120 with the exchange robot 154. Removed by More specifically, the Z-axis direction motor 170 and the X-axis direction motor 172 of the lifting and lowering device 160 and the horizontal moving device 162 are driven by the command of the controller 182, and the clamp mechanism 164 moves in front of the used feeder 90a. Then, the expansion motor 174 is driven by the command of the controller 182, and the clamp mechanism 164 is extended to approach the used feeder 90a and clamp the used feeder 90a. When the used feeder 90a is clamped, the expansion motor 174 is driven by the command of the controller 182, and the clamping mechanism 164 is contracted. As a result, the used feeder 90a is pulled out in the direction of the arrow 190 and removed from the tape feeder holder 120, as shown in FIG.

  Next, in response to a command from the controller 182, the Z-axis direction motor 170 of the lifting device 160 is driven, and the clamp mechanism 164 is moved in the direction of the arrow 192 (downward). As a result, the used feeder 90 a clamped by the clamp mechanism 164 moves between the tape feeder holder 120 and the tape feeder storage case 152. Then, in response to a command from the controller 182, the X-axis direction motor 172 of the horizontal movement device 162 is driven, and the clamp mechanism 164 moves in the X-axis direction. At this time, the X-axis direction motor 172 is driven so that the used feeder 90a clamped by the clamp mechanism 164 moves above the empty slot in which the tape feeder 90 etc. of the tape feeder accommodation case 152 is not accommodated. It is controlled. Then, in response to a command from the controller 182, the Z-axis direction motor 170 of the lifting device 160 is driven, and the clamp mechanism 164 is moved in the direction of the arrow 194 (downward). As a result, the used feeder 90 a clamped by the clamp mechanism 164 is accommodated in the empty slot of the tape feeder accommodation case 152. When the used feeder 90a is accommodated in the slot, the clamp mechanism 164 releases the clamp of the used feeder 90a and contracts due to the command of the controller 182. Further, in the slot in which the mounting scheduled feeder 90b is housed, the code reader 156 identifies the code label of the used feeder 90a, whereby individual information of the used feeder 90a can be read.

  Subsequently, when the tape feeder planned to be mounted on the tape feeder holding table 120 instead of the used feeder 90 a (hereinafter, may be described as “loading planned feeder 90 b”) is stored in the tape feeder storage case 152 In response to a command from the controller 182, the X-axis direction motor 172 of the horizontal movement device 162 is driven, and the clamp mechanism 164 is moved to the front of the mounting scheduled feeder 90b. Then, the extension motor 174 is driven by an instruction of the controller 182, and the clamp mechanism 164 is extended to approach the mounting scheduled feeder 90b and clamp the mounting scheduled feeder 90b.

  Next, in response to a command from the controller 182, the Z-axis direction motor 170 of the lifting and lowering device 160 is driven, and the clamp mechanism 164 is moved upward. As a result, the planned mounting feeder 90 b clamped by the clamp mechanism 164 moves to the front of the tape feeder holder 120. Then, in response to a command from the controller 182, the X-axis direction motor 172 of the horizontal movement device 162 is driven, and the clamp mechanism 164 moves in the X-axis direction. At this time, the drive of the X-axis direction motor 172 is controlled such that the planned loading feeder 90b clamped by the clamp mechanism 164 is moved to the front of the tape feeder holder 120 on which the used feeder 90a has been mounted.

  Subsequently, the extension motor 174 is driven by an instruction of the controller 182, and the clamp mechanism 164 is extended to approach the tape feeder holding base 120, and the mounting scheduled feeder 90b is mounted on the tape feeder holding base 120. Then, when the planned loading feeder 90b is mounted on the tape feeder holding base 120, the clamp mechanism 164 releases the clamp of the planned loading feeder 90b according to the command of the controller 182 and contracts. By the operation of the above-described series of replacement robots 154, it becomes possible to automatically replace the used feeders 90a and the planned mounting feeders 90b.

  Further, in the substrate handling system 10, as shown in FIG. 4, the length of the protrusion 124 is equal to or less than half the length of the bottom surface of the tape feeder 90. Therefore, when the tape feeder 90 is removed from the tape feeder holder 120, it is possible to reduce the amount of movement of the tape feeder 90 in the front-rear direction, that is, in the Y-axis direction. As a result, it becomes possible to smoothly remove the tape feeder 90 from the tape feeder holding base 120 and to reduce the device occupied space in the Y-axis direction.

  In addition, when the planned feeder 90b is accommodated in the tape feeder accommodating base 150, after the used feeder 90a is accommodated in the tape feeder accommodating case 152, the elevating device 160 and the horizontal movement device are instructed by the controller 182. The Z-axis direction motor 170 and the X-axis direction motor 172 of the 162 are driven, and the clamp mechanism 164 moves to the front of the planned mounting feeder 90b. Then, the extension motor 174 is driven by an instruction of the controller 182, and the clamp mechanism 164 is extended to approach the mounting scheduled feeder 90b and clamp the mounting scheduled feeder 90b. The method after the planned mounting feeder 90b is clamped is the same as the method described above, and thus the description thereof is omitted.

  As described above, in the substrate handling system 10, it is possible to accommodate the mounting scheduled feeders 90b not only in the tape feeder accommodation case 152 but also in the tape feeder accommodation base 150. The arrangement space of the tape feeder accommodating table 150 is located outside the movement range of the mounting head 22 by the moving device 24 of the mounting machine 12 and the mounting machine 14, and is a dead space. That is, in the substrate handling system 10, the dead space is used as a storage space for the tape feeders 90 and the like, and a large number of tape feeders 90 can be stored.

  Further, in the substrate-to-board operation system 10, not only the replacement of the used feeder 90a and the mounting scheduled feeder 90b, but also the tape feeder mounted on the tape feeder holder 120 of the mounting machine 12 (hereinafter referred to as "mobile feeder 90c" Can be transferred automatically to the tape feeder holder 120 of the mounting machine 14). Specifically, in response to a command from the controller 182, the Z-axis motor 170 and the X-axis motor 172 of the lifting and lowering device 160 and the horizontal moving device 162 are driven, and the clamp mechanism 164 is mounted on the tape feeder holder 120 of the mounting machine 12. It moves in front of the moving feeder 90c. Then, the extension motor 174 is driven by the command of the controller 182, and the clamp mechanism 164 is extended to approach the moving feeder 90c and clamp the moving feeder 90c. When the moving feeder 90c is clamped, the extension motor 174 is driven by the command of the controller 182, and the clamping mechanism 164 is contracted. As a result, the moving feeder 90 c is removed from the tape feeder holder 120 of the mounting machine 12.

  Next, the X-axis direction motor 172 of the horizontal movement device 162 is driven by the command of the controller 182, and the clamp mechanism 164 moves in the X-axis direction. At this time, the drive of the X-axis direction motor 172 is controlled such that the moving feeder 90c clamped by the clamp mechanism 164 moves to the front of the tape feeder holding stand 120 where the tape feeder 90 etc. of the mounting machine 14 is not mounted. Be done. Then, the extension motor 174 is driven by the command of the controller 182, and the clamp mechanism 164 is extended, thereby approaching the tape feeder holder 120 of the mounting machine 14, and the moving feeder 90c becomes the tape feeder holder of the mounting machine 14. It is attached to 120. When the moving feeder 90c is mounted on the tape feeder holder 120 of the mounting machine 14, the clamp mechanism 164 releases the clamp of the moving feeder 90c and contracts due to the command of the controller 182.

  In addition, when there is no space for mounting the moving feeder 90c on the tape feeder holding stand 120 of the mounting machine 14, a space for mounting the moving feeder 90c is secured on the tape feeder holding stand 120 for the mounting machine 14 The movable feeder 90 c is transferred from the tape feeder holder 120 of the mounting machine 12 to the tape feeder holder 120 of the mounting machine 14. Specifically, the Z-axis direction motor 170 and the X-axis direction motor 172 of the lifting and lowering device 160 and the horizontal moving device 162 are driven by the command of the controller 182, and the clamp mechanism 164 is moved to the tape feeder holding stand 120 of the mounting machine 14. It moves in front of the attached tape feeder 90. In addition, this tape feeder 90 is a tape feeder (Hereinafter, it may describe as "the unnecessary tape feeder 90d.") Which accommodates the electronic component which is not used by the mounting machine 14. As shown in FIG.

  When the clamp mechanism 164 moves in front of the unnecessary tape feeder 90d, the extension motor 174 is driven by the command of the controller 182, and the clamp mechanism 164 is expanded, thereby approaching the tape feeder holder 120 of the mounting machine 14 and unnecessary Clamp the tape feeder 90d. When the unnecessary tape feeder 90d is clamped, the extension motor 174 is driven by the command of the controller 182, and the clamp mechanism 164 is contracted. As a result, the unnecessary tape feeder 90 d is removed from the tape feeder holder 120 of the mounting machine 14.

  Next, the X-axis direction motor 172 of the horizontal movement device 162 is driven by the command of the controller 182, and the clamp mechanism 164 moves in the X-axis direction. At this time, the drive of the X-axis direction motor 172 is controlled such that the unnecessary tape feeder 90d clamped by the clamp mechanism 164 is moved to the front of the tape feeder storage stand 150 on which the tape feeder 90 and the like are not mounted. Then, the extension motor 174 is driven by an instruction of the controller 182, and the clamp mechanism 164 is extended, thereby approaching the tape feeder storage stand 150, and the unnecessary tape feeder 90d is mounted on the tape feeder storage stand 150. When the tape feeder accommodating base 150 has a plurality of empty slots, the unnecessary tape feeder 90d is accommodated in an empty slot near the tape feeder holding base 120 of the mounting device 14 among the plurality of empty slots. This makes it possible to reduce the movement time of the unnecessary tape feeder 90d.

  When the unnecessary tape feeder 90d is attached to the tape feeder accommodating base 150, the clamp mechanism 164 releases the clamp of the unnecessary tape feeder 90d according to a command of the controller 182 and contracts. Thus, a space for mounting the moving feeder 90c on the tape feeder holder 120 of the mounting machine 14 is secured. The method for transferring the moving feeder 90c mounted on the tape feeder holder 120 of the mounting machine 12 in this space is the same as the method described above, and therefore the description thereof is omitted. As described above, in the substrate-to-board operation system 10, the tape feeder 90 mounted on the tape feeder holding base 120 of one of the mounting machine 12 and the mounting machine 14 is automatically transferred to the other tape feeder holding base 120. Is possible. As a result, it becomes possible to optimize the working time in each mounting machine 12, 14.

  Specifically, for example, when the simulation result of the production program is 11 seconds in any of the mounting machines 12 and 14, if production is actually performed, work on one circuit board in the mounting machine 12 The time may be 12 seconds, and the working time for one circuit board in the mounting machine 14 may be 10 seconds. In such a case, the time it takes to manufacture a single circuit board in the work-to-board system 10 is 12 seconds. At this time, by performing part of the mounting work with the mounting machine 12 with the mounting machine 14, the working time for one circuit board in the mounting machine 12 is 11 seconds, and one circuit with the mounting machine 14 It is possible to make the working time for the substrate 11 seconds. That is, by automatically transferring the moving feeder 90c mounted on the tape feeder holding stand 120 of the mounting machine 12 to the tape feeder holding stand 120 of the mounting machine 14, the electronic components accommodated in the moving feeder 90c are The mounting machine 14 can perform the mounting operation instead of the mounting machine 12. This makes it possible to set the working time for one circuit board in mounting machine 12 to 11 seconds, and the working time for one circuit board in mounting machine 14 to 11 seconds, and thus, with substrate processing system 10 The time it takes to manufacture one circuit board is 11 seconds. As described above, in the substrate-to-board operation system 10, each of the mounting machines 12, 12 is transferred by transferring the tape feeders 90 between the tape feeder holding base 120 of the mounting machine 12 and the tape feeder holding base 120 of the mounting machine 14. It becomes possible to achieve optimization of the working time in 14, and it becomes possible to shorten the time which it takes to manufacture one circuit board in the board-to-board working system 10. In addition, transfer of the tape feeder 90 between the tape feeder holding stand 120 of the mounting machine 12 and the tape feeder holding stand 120 of the mounting machine 14 can be performed even during the production of the circuit board. By transferring the tape feeder 90 during the production of the circuit board, it is possible to optimize the working time without interrupting the production, which is very effective.

  Further, by transferring the tape feeders 90 between the tape feeder holding base 120 of the mounting machine 12 and the tape feeder holding base 120 of the mounting machine 14, one tape feeder 90 can be mounted on two mounting machines 12 and 14. Can be shared by As a result, it is not necessary to mount the tape feeders 90 containing the same electronic components on each of the tape feeder holders 120 of the two mounting machines 12 and 14, and it is possible to reduce the cost. Furthermore, when the type of circuit board to be manufactured is changed, replacement of the tape feeder 90, so-called setup replacement, is performed, but the tape feeder mounted on the tape feeder holding stand 120 of the mounting machine 12 or 14 90 can be used as a tape feeder to be replaced at the time of setup change.

  Further, in the substrate-to-substrate operation system 10, not only the transfer of the tape feeder 90, but also the transfer of the cassette type nozzle accommodation unit 130 between the tape feeder support 120 of the mounting machine 12 and the tape feeder support 120 of the mounting machine 14. It is also possible to make replacements. As a result, one cassette type nozzle accommodation unit 130 can be shared by the two attachment machines 12 and 14, and cost reduction can be achieved. In addition, since transfer of the cassette type nozzle accommodation unit 130 can be performed by the same method as transfer of the tape feeder 90, description is abbreviate | omitted.
