This makes it possible to properly exchange the syringe attached to the discharge head with the discharge tool storage compartment in the second substrate processing machine.

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the figures, as embodiments for carrying out the present invention.

[0011] Figure 1 shows an electronic component mounting system 10. The electronic component mounting system 10 consists of one system base 12 and one work unit 16 mounted on the system base 12. As shown in Figure 2, the work unit 16 is equipped with two board-to-board work machines 18. The two board-to-board work machines 18 are arranged adjacent to each other, and the direction in which the two board-to-board work machines 18 are aligned is called the X-axis direction, and the horizontal direction perpendicular to that direction is called the Y-axis direction. Figure 2 is a plan view showing the interior of the work unit 16 from a top-down perspective.

[0012] The two substrate handling machines 18 have substantially the same structure, and each substrate handling machine 18 mainly consists of a work machine body 20, a transport device 22, a moving device 24, a feeder holding base 26, and a station mounting base 28. The work machine body 20 is composed of a frame 32 and a beam 34 (see Figure 1) mounted on the frame 32.

[0013] The transport device 22 is equipped with two conveyor devices 40 and 42. The conveyor devices 40 and 42 are arranged on the frame 32 parallel to each other and extending in the X-axis direction. The conveyor devices 40 and 42 transport the circuit boards they support in the X-axis direction using electromagnetic motors 46 (see Figures 3 and 4). The circuit boards are also held in place at predetermined positions by a board holding device 48 (see Figures 3 and 4).

[0014] The mobile device 24 is an XY robot type mobile device and includes an electromagnetic motor 52 (see Figures 3 and 4) that slides the slider 50 in the X-axis direction and an electromagnetic motor 54 (see Figures 3 and 4) that slides it in the Y-axis direction. The slider 50 can be selectively attached to and detached from either the discharge head 60 or the mounting head 62. The slider 50 has the function of selectively attaching and detaching either the discharge head 60 or the mounting head 62 and functions as a head mounting mechanism. Then, either the discharge head 60 or the mounting head 62 attached to the slider moves to any position on the frame 32 by the operation of the electromagnetic motors 52 and 54.

[0015] The dispensing head 60 dispenses adhesive onto the circuit board. A syringe 64 is attached to the lower end surface of the dispensing head 60. The syringe 64 is filled with adhesive and is connected to an air supply device 66 (see Figure 3) via an air passage. The syringe 64 dispenses adhesive when air is supplied from the air supply device 66. The dispensing head 60 also has a syringe lifting device 68 (see Figure 3) that raises and lowers the syringe 64. The syringe lifting device 68 allows the dispensing head 60 to change the position of the adhesive in the vertical direction. The syringe 64 is detachable from the dispensing head 60, and can be replaced with a new syringe 64 when the amount of adhesive inside decreases. The dispensing head 60 is attached to the slider 50a of the left-hand circuit board work machine 18a of the two circuit board work machines 18.

[0016] The mounting head 62 mounts electronic components on a circuit board. A suction nozzle 70 is provided on the lower end surface of the mounting head 62. The suction nozzle 70 communicates with a positive / negative pressure supply device 72 (see FIG. 4) via a negative pressure air and a positive pressure air passage. The suction nozzle 70 sucks and holds an electronic component by negative pressure and releases the held electronic component by positive pressure. Further, the mounting head 62 has a nozzle lifting device 76 (see FIG. 4) for lifting and lowering the suction nozzle 70. By means of the nozzle lifting device 76, the mounting head 62 changes the vertical position of the electronic component to be held. Note that the suction nozzle 70 is detachable from the mounting head 62 and can be exchanged according to the size of the electronic component or the like. The mounting head 62 is attached to a slider 50b of the right-side substrate handling machine 18b among the two substrate handling machines 18.

[0017] The feeder holding table 26 is disposed at one end in the Y-axis direction in the frame 32, and a plurality of tape feeders 80 can be attached to the feeder holding table 26. The tape feeder 80 accommodates a taped component formed by taping an electronic component in a wound state. Then, the tape feeder 80 feeds out the taped component by a feeding device 82 (see FIGS. 3 and 4). Thereby, the tape feeder 80 attached to the feeder holding table 26 supplies an electronic component at a supply position by feeding out the taped component. Note that the tape feeder 80 is detachable from the feeder holding table 26 and can cope with the replacement of the electronic component or the like.

[0018] Furthermore, the feeder holder 26 can accommodate not only the tape feeder 80 but also the syringe storage feeder 86 (see Figure 5). In other words, either the tape feeder 80 or the syringe storage feeder 86 can be attached to and detached from the feeder holder 26. The syringe storage feeder 86 accommodates syringes 64 and has a shape that is interchangeable between the tape feeder 80 and the feeder holder 26. As shown in Figure 5, the syringe storage feeder 86 has multiple pockets 88 that open on its upper surface. At least one of these pockets 88 is empty, while the remaining pockets 88 contain syringes 64. The dispensing head 60 moves upward into an empty pocket 88, and the syringe 64 on the dispensing head 60 descends, causing the syringe 64 to be stored in the empty pocket 88. Furthermore, the dispensing head 60 from which the syringe 64 has been removed moves above the pocket 88 containing the syringe 64 and descends, thereby attaching the syringe 64 contained in the pocket 88 to the dispensing head 60. In this way, by mounting the syringe-containing feeder 86 on the feeder holder 26, the syringe 64 is exchanged between the dispensing head 60 and the syringe-containing feeder 86. In addition, a heater 90 is provided inside each pocket 88, allowing the contained syringe 64 to be maintained at a predetermined temperature by the heater 90. A detection sensor 92 is also provided in each pocket 88 to detect the remaining amount of adhesive in the syringe, allowing the remaining amount of adhesive in the contained syringe 64 to be managed. Note that in the work unit 16 shown in Figure 2, syringe-containing feeders 86 are not mounted on the feeder holder 26 of each of the two substrate work machines 18, but rather multiple tape feeders 80 are mounted.

[0019] The station mounting base 28 is disposed between the feeder holding base 26 and the transfer device 22 in the frame 32, and one of the syringe station 100 (see FIG. 6) and the nozzle station 102 (see FIG. 7) can be selectively attached to and detached from the station mounting base 28. The station mounting base 28 has functions such as sharing the electrical wiring, connectors, air pipes, and connection parts, which are interfaces for connecting the station mounting base 28 and each station, in order to selectively attach and detach one of the syringe station 100 and the nozzle station 102, and functions as a station mounting mechanism. When the syringe station 100 is attached to the station mounting base 28, the syringe 64 is exchanged between the syringe station 100 and the discharge head 60, and when the nozzle station 102 is attached to the station mounting base 28, the suction nozzle 70 is exchanged between the nozzle station 102 and the mounting head 62.

[0020] As shown in FIG. 6, the syringe station 100 includes a base 110, a syringe tray 112, and a lifting device 114. The lower surface of the base 110 is substantially the same size as the upper surface of the station mounting base 28. A plurality of positioning pins 116 are erected on the upper surface of the station mounting base 28, and a plurality of holes 118 are formed in the lower surface of the base 110 at positions corresponding to the plurality of positioning pins 116. Thereby, the base 110 is disposed in a state of being positioned on the upper surface of the station mounting base 28. The syringe tray 112 is a tray for accommodating the syringe 64, and a plurality of placement holes 120 opening upward are formed in the syringe tray 112. The syringe 64 is not accommodated in at least one of the plurality of placement holes 120, and the syringe 64 is accommodated in the remaining placement holes 120.

[0021] Furthermore, a shutter 122 is provided on the upper surface of the syringe tray 112 so as to be slidable in the left-right direction. The shutter 122 has multiple through holes 124 formed at positions corresponding to multiple mounting holes 120, and each through hole 124 has the same shape as each mounting hole 120. The shutter 122 slides between a position in which the openings of the mounting holes 120 are opened through the through holes 124 and a position in which a part of the opening of the mounting holes 120 is closed by the shutter 122, by the operation of an electromagnetic motor 126 (see Figure 3). In addition, a heater 128 is provided inside each mounting hole 120 so that the stored syringes 64 can be maintained at a predetermined temperature by the heater 128. A detection sensor 130 is also provided in each mounting hole 120 so as to be able to detect the remaining amount of adhesive in the syringes 64, and the remaining amount of adhesive in the stored syringes 64 can be managed.

[0022] The syringe tray 112 is mounted on the base 110 via a lifting device 114 and moves up and down when the lifting device 114 is operated. When a syringe station 100 with this structure is mounted on the station mounting base 28, the dispensing head 60 moves upward into an empty mounting hole 120, the syringe 64 on the dispensing head 60 descends, and the syringe tray 112 rises. At this time, the shutter 122 slides to a position that opens the opening of the mounting hole 120, so that the syringe 64 attached to the dispensing head 60 is housed in the empty mounting hole 120. Also, the dispensing head 60 from which the syringe 64 has been removed moves upward into the mounting hole 120 where the syringe 64 is housed, and then descends, so that the syringe 64 housed in the mounting hole 120 is attached to the dispensing head 60. In this manner, the syringe station 100 is mounted on the station mounting base 28, allowing the syringe 64 to be exchanged between the dispensing head 60 and the syringe station 100. The syringe station 100 is mounted on the station mounting base 28a of the left-hand board handling machine 18a of the two board handling machines 18.

[0023] Furthermore, as shown in Figure 7, the nozzle station 102 includes a base 150, a nozzle tray 152, and a lifting device 154. The lower surface of the base 150 is approximately the same size as the lower surface of the base 110 of the syringe station 100. In other words, the lower surface of the base 150 is approximately the same size as the upper surface of the station mounting base 28. In addition, multiple holes 158 are formed on the lower surface of the base 150 at the same positions as the multiple holes 118 formed on the lower surface of the base 110 of the syringe station 100. In other words, multiple holes 158 are formed on the lower surface of the base 150 at positions corresponding to the multiple positioning pins 116 of the station mounting base 28. As a result, the base 150 is positioned on the upper surface of the station mounting base 28. The nozzle tray 152 is a tray for housing the suction nozzle 70, and the nozzle tray 152 has multiple mounting holes 160 that open on its upper surface. At least one of the multiple mounting holes 160 does not house the suction nozzle 70, while the remaining mounting holes 160 house the suction nozzle 70.

[0024] Furthermore, a shutter 162 is provided on the upper surface of the nozzle tray 152 so as to be slidable in the left-right direction. The shutter 162 has multiple through holes 164 formed at positions corresponding to multiple mounting holes 160, and each through hole 164 has the same shape as each mounting hole 160. The shutter 162 slides between a position in which the openings of the mounting holes 160 are opened through the through holes 164 and a position in which a part of the opening of the mounting holes 160 is closed by the shutter 162, by the operation of an electromagnetic motor 166 (see Figure 4).

[0025] The nozzle tray 152 is mounted on the base 150 via a lifting device 154 and moves up and down when the lifting device 154 is operated. When a nozzle station 102 with this structure is mounted on the station mounting base 28, the mounting head 62 moves upward into an empty mounting hole 160, the suction nozzle 70 on the mounting head 62 descends, and the nozzle tray 152 rises. At this time, the shutter 162 slides to a position that opens the openings of the multiple mounting holes 160, so that the suction nozzle 70 mounted on the mounting head 62 is housed in an empty mounting hole 160. Also, the mounting head 62 from which the suction nozzle 70 has been removed moves upward into the mounting hole 160 where the suction nozzle 70 is housed, and then descends, so that the suction nozzle 70 housed in the mounting hole 160 is attached to the mounting head 62. In this way, when the nozzle station 102 is mounted on the station mounting base 28, the suction nozzle 70 is exchanged between the mounting head 62 and the nozzle station 102. Furthermore, the nozzle station 102 is attached to the station mounting base 28b of the right-hand board processing machine 18b of the two board processing machines 18.

[0026] Furthermore, the substrate handling machine 18a is equipped with a control device 160a as shown in Figure 3. The control device 160a has a controller 162a and a plurality of drive circuits 166a. The controller 162a is a computer-based device equipped with a CPU, ROM, RAM, etc. The controller 162a is connected to the plurality of drive circuits 166a, which in turn are connected to electromagnetic motors 46a, 52a, 54a, 126, substrate holding device 48a, air supply device 66, syringe lifting device 68, delivery device 82, lifting device 114, and heater 128. As a result, the operation of the transport device 22a, moving device 24a, etc. is controlled by the controller 162a. The controller 162a is also connected to a detection sensor 130 and acquires detection values ​​from the detection sensor 130.

[0027] Furthermore, the substrate handling machine 18b is equipped with a control device 160b as shown in Figure 4. The control device 160b has a controller 162b and a plurality of drive circuits 166b. The controller 162b is a computer-based device equipped with a CPU, ROM, RAM, etc. The controller 162b is connected to the plurality of drive circuits 166b, which in turn are connected to electromagnetic motors 46b, 52b, 54b, 166, a substrate holding device 48b, a positive / negative pressure supply device 72, a nozzle lifting device 76, a delivery device 82, and a lifting device 154. As a result, the operation of the transport device 22b, the moving device 24b, etc. is controlled by the controller 162b.

[0028] In the work unit 16, as described above, adhesive is dispensed onto the circuit board in the board-to-board work machine 18a, and electronic components are mounted onto the circuit board in the board-to-board work machine 18b. Specifically, the circuit board is loaded into the board-to-board work machine 18a, and the transport device 22a of the board-to-board work machine 18a transports the circuit board to the work position and holds it fixedly in that position. Then, the dispensing head 60 moves above the circuit board by the operation of the moving device 24a and dispenses adhesive onto the upper surface of the circuit board. At this time, the dispensing head 60 dispenses adhesive to the position on the circuit board where the electronic components are to be mounted. When the dispensing of adhesive by the dispensing head 60 is completed, the circuit board is unloaded from the board-to-board work machine 18a and loaded into the board-to-board work machine 18b. When the circuit board is loaded into the board-to-board work machine 18b, the transport device 22b of the board-to-board work machine 18b transports the circuit board to the work position and holds it fixedly in that position. Furthermore, in the circuit board work machine 18b, the tape feeder 80 feeds out the tape-formed components and supplies the electronic components to the supply position. Then, the mounting head 62 moves above the supply position of the electronic components by the operation of the moving device 24b and picks up and holds the electronic components with the suction nozzle 70. Then, the mounting head 62 moves above the planned mounting position of the electronic components on the circuit board, that is, above the position where the adhesive is being dispensed, by the operation of the moving device 24b, and mounts the held electronic components onto the circuit board. As a result, the electronic components are mounted on the circuit board in a state where they are bonded to the predetermined position with adhesive.

[0029] Thus, in the work unit 16, adhesive is dispensed onto the circuit board by the substrate application machine 18a, and the substrate application machine 18a functions as an application machine that applies adhesive to the circuit board. For this reason, temperature control and remaining amount check of the syringe 64 used to apply the adhesive are performed by the syringe storage feeder 86 and the syringe station 100. Also, when the syringe 64 attached to the dispensing head 60 becomes empty, it must be replaced with a new syringe. However, if there is no syringe station 100 and syringe replacement is performed only by the syringe storage feeder 86, multiple syringe storage feeders 86 are required for the dispensing head 60 to either hold the syringe 64 or return the syringe while the syringe replacement is being performed. Furthermore, when applying multiple types of adhesive to the substrate, it is necessary to prepare a syringe storage feeder for each type. For this reason, it is necessary to attach multiple syringe storage feeders 86 to the feeder holding base 26a. Considering these factors, by installing the syringe station 100 on the substrate handling machine 18a, it becomes possible to prepare spare syringes in advance at the syringe station 100 via the syringe storage feeder 86. This reduces the number of syringe storage feeders 86 that need to be attached to the feeder holder 26a, allowing for more efficient syringe operation.

[0030] Furthermore, in the work unit 16, adhesive is dispensed onto the circuit board by the board-to-board work machine 18a, and electronic components are mounted onto the circuit board by the board-to-board work machine 18b. Therefore, the board-to-board work machine 18a functions as an adhesive application machine for applying adhesive to the circuit board, and the board-to-board work machine 18b functions as a mounting machine for mounting electronic components onto the circuit board. In this way, since the board-to-board work machine 18b functions as a mounting machine, a tape feeder 80 that supplies the electronic components to be mounted onto the circuit board by the board-to-board work machine 18b is attached to the feeder holder 26b of the board-to-board work machine 18b. On the other hand, since the board-to-board work machine 18a, which functions as an adhesive application machine, does not perform the mounting of electronic components, there is no need to attach the tape feeder 80 to the feeder holder 26a of the board-to-board work machine 18a. However, while mounting work is being performed on the board-to-board work machine 18b, it may be necessary to replace the tape feeder 80 attached to the feeder holder 26b of the board-to-board work machine 18b with a new tape feeder 80 in order to replenish electronic components, etc. In such cases, if a replacement tape feeder 80 is attached to the feeder holder 26a of the board-to-board work machine 18a, which is located next to the board-to-board work machine 18b, the operator can easily perform the tape feeder 80 replacement work on the board-to-board work machine 18b. Also, for example, if the tape feeder 80 required for the mounting work scheduled to be performed on the board-to-board work machine 18b after the mounting work being performed on the board-to-board work machine 18b (hereinafter referred to as "scheduled mounting work") is attached to the feeder holder 26a of the board-to-board work machine 18a, the operator can easily perform the setup work for the scheduled mounting work. In other words, in the setup work for the scheduled mounting operation, the worker only needs to move the tape feeder 80 required for the scheduled mounting operation from the feeder holder 26a of the substrate mounting machine 18a to the feeder holder 26b of the substrate mounting machine 18b, thus making the setup work for the scheduled mounting operation easy.

[0031] In light of these considerations, tape feeders 80 that supply electronic components to be mounted on circuit boards by the circuit board work machine 18b are attached not only to the feeder holder 26b of the circuit board work machine 18b, but also to the feeder holder 26a of the circuit board work machine 18a. In other words, the feeder holder 26a of the circuit board work machine 18a can also function as a temporary storage location for the tape feeders 80 used in the circuit board work machine 18b. Furthermore, by attaching many tape feeders 80 to the feeder holder 26a of the circuit board work machine 18a, its function as a temporary storage location for tape feeders 80 is enhanced. For this reason, it is preferable to attach only tape feeders 80 to the feeder holder 26a of the circuit board work machine 18a. In this way, if only tape feeders 80 are attached to the feeder holder 26a of the circuit board work machine 18a, it is not possible to attach a syringe storage feeder 86 to the feeder holder 26a. Therefore, in a substrate handling machine 18a where only the tape feeder 80 is attached to the feeder holding base 26a, it is not possible to replace the syringe 64 using the syringe storage feeder 86.

[0032] Therefore, in the circuit board work machine 18a, a syringe station 100 is attached to the station mounting base 28a, and the syringe 64 is replaced using the syringe station 100. In addition, in the circuit board work machine 18b, the mounting of electronic components is performed, so it is necessary to replace the suction nozzle 70 attached to the mounting head 62 according to the size of the electronic components. For this reason, in the circuit board work machine 18b, a nozzle station 102 is attached to the station mounting base 28b.

[0033] Thus, in the work unit 16, adhesive application is performed in the board-to-board work machine 18a, and the mounting of electronic components is performed in the board-to-board work machine 18b. For this reason, as preparation work before the work is performed in the work unit 16, the discharge head 60 is attached to the slider 50a of the board-to-board work machine 18a, and the mounting head 62 is attached to the slider 50b of the board-to-board work machine 18b. In addition, the syringe station 100 is attached to the station mounting base 28a of the board-to-board work machine 18a, and the nozzle station 102 is attached to the station mounting base 28b of the board-to-board work machine 18b. Furthermore, the tape feeder 80 used in the board-to-board work machine 18b is attached to the feeder holding base 26a of the board-to-board work machine 18a, and the tape feeder 80 used in the board-to-board work machine 18b is also attached to the feeder holding base 26b of the board-to-board work machine 18b.

[0034] Furthermore, the slider 50 can be selectively fitted with a dispensing head 60 and a mounting head 62, and the station mounting base 28 can be selectively fitted with a syringe station 100 and a nozzle station 102. Therefore, mounting work can be performed on each of the two board-to-board work machines 18. In other words, as a setup operation before work is performed on the work unit 16, the mounting head 62 is attached to the slider 50a of board-to-board work machine 18a, and the mounting head 62 is attached to the slider 50b of board-to-board work machine 18b. Also, the nozzle station 102 is attached to the station mounting base 28a of board-to-board work machine 18a, and the nozzle station 102 is attached to the station mounting base 28b of board-to-board work machine 18b. Furthermore, the tape feeder 80 used in the board-to-board work machine 18a is attached to the feeder holder 26a of the board-to-board work machine 18a, and the tape feeder 80 used in the board-to-board work machine 18b is attached to the feeder holder 26b of the board-to-board work machine 18b. As a result, the mounting work is performed on each of the two board-to-board work machines 18.

[0035] Furthermore, it is possible to perform the adhesive application work on each of the two board-to-board work machines 18. Specifically, as a setup step before the work is performed on the work unit 16, the discharge head 60 is attached to the slider 50a of board-to-board work machine 18a, and the discharge head 60 is attached to the slider 50b of board-to-board work machine 18b. In addition, the syringe station 100 is attached to the station mounting base 28a of board-to-board work machine 18a, and the syringe station 100 is attached to the station mounting base 28b of board-to-board work machine 18b. As a result, the adhesive application work is performed on each of the two board-to-board work machines 18.

[0036] Thus, in the substrate processing machine 18, the discharge head 60 and the mounting head 62 can be selectively attached to and detached from the slider 50, and the syringe station 100 and the nozzle station 102 can be selectively attached to and detached from the station mounting base 28. Therefore, by simply changing the work head attached to the slider 50 and changing the station attached to the station mounting base 28, the substrate processing machine 18 can function as either a discharge machine or a mounting machine.

[0037] Furthermore, in the aforementioned substrate handling machine 18a, the syringe storage feeder 86 is not attached to the feeder holder 26a, and only the tape feeder 80 is attached. On the other hand, as shown in Figure 8, by attaching the syringe storage feeder 86 in addition to the tape feeder 80 to the feeder holder 26a, it becomes possible to replace many syringes 64 in the substrate handling machine 18a. Specifically, in the substrate handling machine 18a shown in Figure 2, since the syringe storage feeder 86 is not attached to the feeder holder 26a, the number of syringes 64 usable in the substrate handling machine 18a is the sum of the number of syringes 64 attached to the discharge head 60 and the number of syringes 64 stored in the syringe station 100. On the other hand, in the substrate handling machine 18a shown in Figure 8, a syringe storage feeder 86 is attached to the feeder holder 26a. Therefore, the number of syringes 64 usable in the substrate handling machine 18a is the sum of the number of syringes 64 attached to the discharge head 60, the number of syringes 64 stored in the syringe station 100, and the number of syringes 64 stored in the syringe storage feeder 86. For this reason, by attaching not only the tape feeder 80 but also the syringe storage feeder 86 to the feeder holder 26a, it becomes possible to replace many syringes 64 in the substrate handling machine 18a.

[0038] Furthermore, in the substrate handling machine 18a shown in Figure 8, the syringe 64 can be replaced between the syringe station 100 and the syringe storage feeder 86. Specifically, when the amount of adhesive remaining in a syringe 64 stored in the syringe station 100 becomes low, the syringe 64 with the low amount of adhesive remaining in the syringe station 100 is transferred by the dispensing head 60 to an empty pocket 88 in the syringe storage feeder 86. Then, a new syringe 64 from the syringe storage feeder 86 is transferred by the dispensing head 60 to an empty mounting hole 120 in the syringe station 100. This makes it possible to replenish the syringe station 100 with a new syringe 64 from the syringe storage feeder 86.

[0039] In the above embodiment, the electronic component mounting system 10 is an example of a board-to-board work system. The board-to-board work machine 18a is an example of a second board-to-board work machine. The board-to-board work machine 18b is an example of a first board-to-board work machine. The feeder holder 26 is an example of a feeder holder. The station mounting base 28 is an example of a storage unit mounting mechanism. The slider 50 is an example of a head mounting mechanism. The discharge head 60 is an example of a discharge head. The mounting head 62 is an example of a mounting head. The syringe 64 is an example of a discharge tool. The suction nozzle 70 is an example of a holder. The tape feeder 80 is an example of a component supply feeder. The syringe storage feeder 86 is an example of a discharge tool storage feeder. The syringe station 100 is an example of a discharge tool storage unit. The nozzle station 102 is an example of a holder storage unit. The heater 128 is an example of a temperature control device. The detection sensor 130 is an example of a detection sensor.

[0040] In the embodiment described above, the following effects are achieved.

[0041] In the substrate processing machine 18, the dispensing head 60 and the mounting head 62 can be selectively attached to and detached from the slider 50, and the syringe station 100 and the nozzle station 102 can be selectively attached to and detached from the station mounting base 28. As a result, by simply changing the work head attached to the slider 50 and changing the station attached to the station mounting base 28, the substrate processing machine 18 can function as either a dispensing machine or a mounting machine.

[0042] Furthermore, in the syringe station 100, a heater 128 is installed inside the mounting hole 120. This allows the syringe 64 housed in the mounting hole 120 to be maintained at a predetermined temperature by the heater 128. In addition, a detection sensor 130 for detecting the remaining amount of adhesive in the syringe is also installed in the mounting hole 120. This allows the remaining amount of adhesive in the syringe 64 housed in the mounting hole 120 to be managed.

[0043] Furthermore, in the substrate processing machine 18a shown in Figure 8, a discharge head 60 is attached to the slider 50, a syringe station 100 is attached to the station mounting base 28, and a syringe storage feeder 86 is attached to the feeder holding base 26. This makes it possible to exchange syringes 64 between the syringe station 100 and the syringe storage feeder 86 using the discharge head 60, and to replenish the syringe station 100 with new syringes 64 from the syringe storage feeder 86.

[0044] Furthermore, as a setup step before the work is performed in the work unit 16 shown in Figure 2, the discharge head 60 is attached to the slider 50a of the substrate work machine 18a, and the mounting head 62 is attached to the slider 50b of the substrate work machine 18b. In addition, the syringe station 100 is attached to the station mounting base 28a of the substrate work machine 18a, and the nozzle station 102 is attached to the station mounting base 28b of the substrate work machine 18b. Moreover, the tape feeder 80 used in the substrate work machine 18b is attached to the feeder holding base 26a of the substrate work machine 18a, and the tape feeder 80 used in the substrate work machine 18b is also attached to the feeder holding base 26b of the substrate work machine 18b. This allows the feeder holder 26a of the substrate processing machine 18a to function as a temporary storage location for the tape feeder 80 used in the substrate processing machine 18b, enabling the operator to easily transfer the tape feeder 80 required by the substrate processing machine 18b from the feeder holder 26a to the feeder holder 26b.

[0045] It should be noted that the present invention is not limited to the above embodiments, and can be implemented in various forms with various modifications and improvements based on the knowledge of those skilled in the art. Specifically, for example, in the above embodiment, a tape feeder 80 used in a substrate-to-substrate work machine 18b, which functions as a mounting work machine and is located next to the substrate-to-substrate work machine 18a, is attached to the feeder holder 26a of the substrate-to-substrate work machine 18a, which functions as a dispensing work machine. On the other hand, if the electronic component mounting system 10 has three or more substrate-to-substrate work machines, a tape feeder 80 used in a substrate-to-substrate work machine that does not function as a mounting work machine and is not adjacent to the substrate-to-substrate work machine may be attached to the feeder holder 26 of the substrate-to-substrate work machine that functions as a dispensing work machine. Alternatively, a tape feeder 80 used in multiple substrate-to-substrate work machines that function as mounting work machines may be attached to the feeder holder 26 of the substrate-to-substrate work machine that functions as a dispensing work machine.

[0046] Furthermore, in the substrate processing machine 18a shown in Figure 8, the syringe 64 is transferred between the syringe station 100 and the syringe storage feeder 86 by the discharge head 60, and the syringe 64 is replenished in the syringe station 100 from the syringe storage feeder 86. Alternatively, the discharge head 60 may directly exchange the syringe 64 between itself and the syringe storage feeder 86.

[0047] Furthermore, in the above embodiment, a tape feeder 80 is used as the parts supply feeder attached to the feeder holder 26, but other parts supply feeders such as stick feeders and bowl feeders may also be used.

[0048] Furthermore, in the above embodiment, a suction nozzle 70 is used as a holder for the parts, but other holders such as chucks may also be used. [Explanation of symbols]
