[0011] The supply method disclosed herein is a supply method for supplying suction nozzles to a component mounting device that mounts components on a board using suction nozzles held by a nozzle holding unit, and includes processes of determining a mounting position on a nozzle changer for the suction nozzle to be mounted on the nozzle changer, transporting the nozzle changer with the suction nozzle mounted at the determined mounting position to the component mounting device by a transport conveyor, and removing the suction nozzle mounted on the nozzle changer from the nozzle changer by the nozzle holding unit based on the determined mounting position.

[0012] With this, the mounting position of the suction nozzle is determined in advance, for example, during off-site setup before the nozzle changer is transported, and then the nozzle changer is transported and the suction nozzle is removed based on the determined mounting position. This eliminates the need to identify the mounting position of the suction nozzle by taking an image of each suction nozzle with a camera, thereby improving work efficiency when supplying suction nozzles.

[0013] In addition, first suction nozzle information regarding suction nozzles held by the component mounting device and second suction nozzle information regarding suction nozzles required for future production may be acquired, and suction nozzles not included in the first suction nozzle information may be identified from the second suction nozzle information, and the nozzle changer equipped with the identified suction nozzle may be transported to the component mounting device by the transport conveyor at a determined mounting position.

[0014] According to this, among the second suction nozzle information, suction nozzles that are not included in the first suction nozzle information are suction nozzles that are required for future production but are not held by the component mounting device, and such suction nozzles can be supplied to the component mounting device.

[0015] In addition, identification information for identifying the nozzle changer is stored in a memory unit, and a code attached to the nozzle changer transported to the component mounting device by the transport conveyor is read and compared to determine whether the identification information included in the code matches the identification information stored in the memory unit.If the identification information included in the code matches the identification information stored in the memory unit, the suction nozzle mounted on the nozzle changer may be removed from the nozzle changer by the nozzle holding unit based on the determined mounting position.

[0016] According to this, the identification information of the nozzle changer to be transported is stored in a memory unit, and by checking whether the identification information contained in the code attached to the transported nozzle changer matches the identification information stored in the memory unit, it is possible to determine whether the correct nozzle changer to be transported is being transported.

[0017] The nozzle changer may also have a shutter that prevents the suction nozzle from falling off, and the shutter may move between an open position where the suction nozzle can be removed and a closed position where the suction nozzle cannot be removed. If the identification information included in the code matches the identification information stored in the memory unit, the shutter may be moved from the closed position to the open position, and the suction nozzle mounted on the nozzle changer may be removed from the nozzle changer by the nozzle holding unit.

[0018] This allows the shutter to prevent the suction nozzle from falling off the nozzle changer, and the suction nozzle can be removed when the identification information contained in the code attached to the transported nozzle changer matches the identification information stored in the memory unit.

[0019] Furthermore, if the identification information included in the code does not match the identification information stored in the storage unit, an error may be reported.

[0020] This makes it possible to notify the user that the correct nozzle changer that should have been transported has not been transported.

[0021] The storage unit may store identification information for identifying the nozzle changer and a mounting position on the nozzle changer in association with each other.

[0022] According to this, when the identification information contained in the code attached to the transported nozzle changer matches the identification information stored in the memory unit, the suction nozzle can be extracted based on the mounting position linked to the identification information.

[0023] The nozzle changer with the suction nozzle mounted at the determined mounting position may be transported by the transport conveyor to a plurality of the component mounting devices lined up in a row, and each of the plurality of component mounting devices may remove the suction nozzle from the nozzle changer by its nozzle holder. For example, the component mounting device located most upstream of the plurality of component mounting devices may read the code.

[0024] According to this, the code attached to the nozzle changer is read at the component mounting device located at the most upstream position among multiple component mounting devices lined up in a row, where the nozzle changer being transported arrives first, thereby making it possible to quickly determine whether the correct nozzle changer that should be transported is being transported.

[0025] In addition, the type of suction nozzle to be mounted on the nozzle changer and the mounting position on the nozzle changer may be determined, the nozzle changer with the determined type of suction nozzle mounted at the determined mounting position may be transported to the component mounting device by the transport conveyor, and the suction nozzle mounted on the nozzle changer may be removed from the nozzle changer by the nozzle holding unit based on the determined type and the determined mounting position.

[0026] With this, the type and mounting position of the suction nozzle are determined in advance, for example, during off-site setup before the nozzle changer is transported, and then the nozzle changer is transported and the suction nozzle is taken out based on the determined type and mounting position. This eliminates the need to identify the type and mounting position of the suction nozzle by photographing each suction nozzle with a camera, thereby improving work efficiency when supplying suction nozzles.

[0027] In addition, it may be determined whether the type of suction nozzle removed from the nozzle changer by the nozzle holding unit is correct based on an image obtained by capturing an image of the suction nozzle held by the nozzle holding unit or the flow rate of the suction nozzle held by the nozzle holding unit.

[0028] In this way, it is possible to determine whether the type of the removed suction nozzle is correct or not based on the image obtained by capturing an image of the suction nozzle or the flow rate of the suction nozzle.

[0029] The mounting system of the present disclosure comprises a component mounting device that mounts components on a board using a suction nozzle held by a nozzle holding unit, a transport conveyor, a nozzle changer, and a management device, wherein the management device has a determination unit that determines the mounting position of the suction nozzle mounted on the nozzle changer, the transport conveyor transports the nozzle changer with the suction nozzle mounted at the determined mounting position to the component mounting device, and the component mounting device has a control unit that controls the nozzle holding unit to remove the suction nozzle mounted on the nozzle changer from the nozzle changer based on the determined mounting position.

[0030] With this, the mounting position of the suction nozzle is determined in advance, for example, during off-site setup before the nozzle changer is transported, and then the nozzle changer is transported and the suction nozzle is removed based on the determined mounting position. This eliminates the need to identify the mounting position of the suction nozzle by taking an image of each suction nozzle with a camera, thereby improving work efficiency when supplying suction nozzles.

[0031] The management device may also have an acquisition unit that acquires first suction nozzle information regarding suction nozzles held by the component mounting device and second suction nozzle information regarding suction nozzles required for future production, an identification unit that identifies suction nozzles in the second suction nozzle information that are not included in the first suction nozzle information, and an instruction unit that instructs a mounting operation to mount the identified suction nozzle at a determined mounting position in the nozzle changer.

[0032] According to this, among the second suction nozzle information, suction nozzles that are not included in the first suction nozzle information are suction nozzles that are required for future production but are not held by the component mounting device, and such suction nozzles can be supplied to the component mounting device.

[0033] The component mounting device may further include a memory unit that stores identification information for identifying the nozzle changer, an imaging unit that reads a code attached to the nozzle changer transported to the component mounting device by the transport conveyor, and a comparison unit that checks whether the identification information included in the code matches the identification information stored in the memory unit, and the control unit may control the nozzle holding unit to remove the suction nozzle mounted on the nozzle changer from the nozzle changer based on the determined mounting position when the identification information included in the code matches the identification information stored in the memory unit.

[0034] According to this, the identification information of the nozzle changer to be transported is stored in a memory unit, and by checking whether the identification information contained in the code attached to the transported nozzle changer matches the identification information stored in the memory unit, it is possible to determine whether the correct nozzle changer to be transported is being transported.

[0035] The nozzle changer may also have a shutter that prevents the suction nozzle from falling off, and a shutter drive mechanism that moves the shutter between an open position where the suction nozzle can be removed and a closed position where the suction nozzle cannot be removed, and when the identification information included in the code matches the identification information stored in the memory unit, the shutter drive mechanism moves the shutter from the closed position to the open position, and the control unit may control the nozzle holding unit to remove the suction nozzle mounted on the nozzle changer from the nozzle changer.

[0036] This allows the shutter to prevent the suction nozzle from falling off the nozzle changer, and the suction nozzle can be removed when the identification information contained in the code attached to the transported nozzle changer matches the identification information stored in the memory unit.

[0037] In addition, the nozzle changer may have a battery that supplies power to the shutter drive mechanism, and the management device may have a command unit that issues a command to the shutter drive mechanism to move the shutter to an open position when the identification information included in the code matches the identification information stored in the memory unit, and the shutter drive mechanism may, upon receiving the command, move the shutter from the closed position to the open position using power supplied from the battery.

[0038] This allows the shutter to be automatically moved from the closed position to the open position.

[0039] The component mounting device may also include a notification unit that notifies an error when the identification information included in the code does not match the identification information stored in the storage unit.

[0040] This makes it possible to notify the user that the correct nozzle changer that should have been transported has not been transported.

[0041] The storage unit may store identification information for identifying the nozzle changer and a mounting position on the nozzle changer in association with each other.

[0042] According to this, when the identification information contained in the code attached to the transported nozzle changer matches the identification information stored in the memory unit, the suction nozzle can be extracted based on the mounting position linked to the identification information.

[0043] The mounting system may further include a plurality of component mounting devices arranged in a line, the transport conveyor transporting the nozzle changer with the suction nozzle mounted at the determined mounting position to the plurality of component mounting devices, and the control unit of each of the plurality of component mounting devices controlling the nozzle holder to remove the suction nozzle from the nozzle changer. For example, the imaging unit of the component mounting device located most upstream of the plurality of component mounting devices may read the code.

[0044] According to this, the code attached to the nozzle changer is read at the component mounting device located at the most upstream position among multiple component mounting devices lined up in a row, where the nozzle changer being transported arrives first, thereby making it possible to quickly determine whether the correct nozzle changer that should be transported is being transported.

[0045] In addition, the determination unit may determine the type of suction nozzle to be mounted on the nozzle changer and the mounting position on the nozzle changer, the transport conveyor may transport the nozzle changer, with the determined type of suction nozzle mounted, to the determined mounting position to the component mounting device, and the control unit may control the nozzle holding unit to remove the suction nozzle mounted on the nozzle changer from the nozzle changer based on the determined type and the determined mounting position.

[0046] With this, the type and mounting position of the suction nozzle are determined in advance, for example, during off-site setup before the nozzle changer is transported, and then the nozzle changer is transported and the suction nozzle is taken out based on the determined type and mounting position. This eliminates the need to identify the type and mounting position of the suction nozzle by photographing each suction nozzle with a camera, thereby improving work efficiency when supplying suction nozzles.

[0047] The component mounting device may also have a judgment unit that judges whether the type of suction nozzle removed from the nozzle changer by the nozzle holding unit is correct based on an image obtained by imaging the suction nozzle held by the nozzle holding unit or the flow rate of the suction nozzle held by the nozzle holding unit.

[0048] In this way, it is possible to determine whether the type of the removed suction nozzle is correct or not based on the image obtained by capturing an image of the suction nozzle or the flow rate of the suction nozzle.

[0049] The embodiments described below are all comprehensive or specific examples, and the numerical values, shapes, materials, components, arrangement and connection of the components, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present disclosure.

[0050] (Embodiment) Hereinafter, the embodiment will be described with reference to FIGS.

[0051] First, the configuration of a mounting system 1 according to the embodiment will be described with reference to FIG.

[0052] FIG. 1 is a side view of a mounting system 1 according to an embodiment.

[0053] The mounting system 1 has a function of producing a mounted board by mounting components such as electronic components on a board by soldering or the like. The mounted board may also be produced by bonding components to the board with adhesive or the like. To produce the mounted board, the mounting system 1 includes a production line 1a connecting a board supply device M1, a board transfer device M2, a printing device M3, an inspection device M4, component mounting devices M5 and M6, an inspection device M7, a reflow device M8, and a board recovery device M9, and a management device 3 connected to the production line 1a via a network 2. Specifically, each device constituting the production line 1a, including the component mounting devices M5 and M6, is connected to the management device 3 via the network 2, and the management device 3 controls production management for the production line 1a. The network 2 is, for example, a wired network, but may also be a wireless network. The production line 1a is provided with a transport conveyor 11, which transports boards and the like from upstream (the left side of FIG. 1 ) to downstream (the right side of FIG. 1 ).

[0054] Board supply device M1 supplies boards to be mounted with components. The supplied boards are then carried into printing device M3 via board transfer device M2. Printing device M3 screen-prints paste-like solder, such as cream solder, onto the electrodes formed on the board for joining components. Inspection device M4 performs printing inspections, including judging the quality of the solder printed on the board and detecting misalignment of the solder print relative to the electrodes.

[0055] Component placement devices M5 and M6 sequentially mount electronic components onto the board 6 on which solder has been printed by the printing device M3. An inspection device M7 inspects the component mounting state on the board after the electronic components have been mounted. A reflow device M8 heats the board after the electronic components have been mounted according to a specified reflow temperature profile, melting the solder and solder-bonding the electronic components to the board. A board removal device M9 removes the board after reflow, i.e., the finished board on which the electronic components have been mounted.

[0056] The component mounting device M5 and the component mounting device M6 basically have the same functions and configurations, except that the component mounting device M5 is the component mounting device located most upstream of the component mounting devices M5 and M6. Therefore, the following description will focus on the component mounting device M5 of the component mounting devices M5 and M6. Note that three or more component mounting devices may be provided.

[0057] Next, the configuration of the component mounting device M5 will be described with reference to FIGS.

[0058] FIG. 2 is a perspective view of the component mounting apparatus M5 according to the embodiment.

[0059] FIG. 3 is a front view of the mounting head 13 according to the embodiment.

[0060] The component mounting device M5 is a device that mounts components on a circuit board. The component mounting device M5 has a transport conveyor 11 and multiple part feeders 12 on a base 10, and is equipped with a freely movable mounting head 13. The mounting head 13 is an example of a nozzle holding unit. A circuit board camera 14 is provided on the mounting head 13, and a component camera 15 and a nozzle exchange table 16 are attached to the base 10. The circuit board camera 14 is an example of an imaging unit. For ease of explanation, the direction in which the circuit board is transported by the transport conveyor 11 (arrow A shown in Figure 2) is defined as the X-axis direction, the direction perpendicular to the X-axis direction in a horizontal plane is defined as the Y-axis direction, and the up and down direction is defined as the Z-axis direction.

[0061] The transfer conveyor 11 supports both ends of the board from below, transports it in the X-axis direction, and positions it at a predetermined work position. The parts feeders 12 are tape feeders in this example, and continuously supply parts to the respective part supply ports 12p.

[0062] 2, component mounting device M5 is equipped with a head moving mechanism 21 having a Y-axis beam 21a extending in the Y-axis direction and an X-axis beam 21b extending in the X-axis direction, and mounting head 13 is attached to X-axis beam 21b. X-axis beam 21b moves in the Y-axis direction along Y-axis beam 21a, and mounting head 13 moves in the X-axis direction along X-axis beam 21b, so that mounting head 13 moves above base 10 within the XY plane (horizontal plane).

[0063] 3, the mounting head 13 is equipped with a plurality of shaft members 22 that extend and protrude downward, and a suction nozzle 23 is detachably attached to each shaft member 22. The suction nozzle 23 has a base 23a, a tube portion 23b that extends downward from the base 23a, and a disk-shaped flange portion 23c that is provided between the base 23a and the tube portion 23b, and the base 23a is detachably attached to the lower end of the shaft member 22. The suction nozzle 23 sucks a component onto the lower end of the tube portion 23b by using vacuum suction force supplied via the shaft member 22.

[0064] The board camera 14 has an imaging field of view facing downward, and moves above the base 10 as the mounting head 13 moves, recognizing from above the board positioned by the transfer conveyor 11. The component camera 15 is provided in an area on the base 10 between the transfer conveyor 11 and the parts feeder 12 with its imaging field of view facing upward, and images from below the component picked up by the lower end of the suction nozzle 23. For example, the nozzle exchange table 16 is provided at a position adjacent to the component camera 15 on the base 10. The nozzle exchange table 16 houses a replacement suction nozzle 23 that can be attached to the mounting head 13.

[0065] When the component mounting device M5 mounts components on a board, the board is transported by the transport conveyor 11. Meanwhile, if the type of board to be mounted changes in future production, the type of components required for future production may also change, and the type of suction nozzle 23 required for future production may also change. In such a case, the suction nozzle 23 currently attached to the mounting head 13 or the suction nozzle 23 housed in the nozzle exchange table 16 may not be able to accommodate future production. In this disclosure, in such a case, the nozzle changer 18 equipped with the suction nozzle 23 to supply to the component mounting device M5 is transported to the component mounting device M5 by the transport conveyor 11. FIG. 2 shows the nozzle changer 18 transported to the component mounting device M5 by the transport conveyor 11. Unlike the fixed nozzle exchange table 16, the nozzle changer 18 is a transportable nozzle changer.

[0066] Here, the configuration of the nozzle changer 18 will be described with reference to FIGS. 4A and 4B.

[0067] FIG. 4A is a plan view of the nozzle changer 18 (closed) according to the embodiment.

[0068] FIG. 4B is a plan view of the nozzle changer 18 (open) according to the embodiment.

[0069] The nozzle changer 18 has a base portion 41 and a shutter 42 provided above the base portion 41. The base portion 41 is made of a block-shaped member and has a plurality of nozzle insertion holes 41H that are arranged in a matrix and open upward.

[0070] The shutter 42 is made of a rectangular plate-shaped member and has a plurality of shutter openings 42M corresponding to the row (row aligned in the X-axis direction) of the plurality of nozzle insertion holes 41H provided in the base portion 41. The shutter 42 is slidable between a closed position (FIG. 4A) relative to the base portion 41 and an open position (FIG. 4B) moved from the closed position in the X-axis direction. In other words, the shutter 42 moves between an open position where the suction nozzle 23 can be removed and a closed position where the suction nozzle 23 cannot be removed.

[0071] When the shutter 42 is in the open position, the tube portion 23b of the suction nozzle 23 can be inserted from above into the nozzle insertion hole 41H through the shutter opening 42M of the shutter 42, and the suction nozzle 23 with the tube portion 23b inserted into the nozzle insertion hole 41H can also be pulled out upward. When the shutter 42 is in the closed position, the flange portion 23c of the suction nozzle 23 with the tube portion 23b inserted into the nozzle insertion hole 41H is located below the shutter 42. Therefore, when the shutter 42 is in the closed position, even if the suction nozzle 23 is pulled up, the flange portion 23c interferes with the underside of the shutter 42, so the suction nozzle 23 cannot be pulled out upward. In this way, the shutter 42 prevents the suction nozzle 23 from falling off.

[0072] Furthermore, a code 40 is attached to the nozzle changer 18. The code 40 is not particularly limited, but may be a one-dimensional code such as a barcode, or a two-dimensional code such as a QR code (registered trademark). The code 40 includes identification information for identifying the nozzle changer 18 to which the code 40 is attached.

[0073] Next, the configuration of the control system of the mounting system 1 will be described with reference to Fig. 5 to Fig. 7. The configuration of the control system of the management device 3 will be described with Fig. 5, the configuration of the control system of the component mounting device M5 will be described with Fig. 6, and the configuration of the control system of the nozzle changer 18 will be described with Fig. 7.

[0074] FIG. 5 is a block diagram showing the configuration of the management device 3 according to the embodiment.

[0075] The management device 3 has a control unit 100, an operation / input unit 110, a display unit 120, a storage unit 130, and a communication unit 140. The control unit 100 is a CPU device that executes the processing functions of the management device 3, and controls functional components such as an acquisition unit 101, an identification unit 102, a decision unit 103, an instruction unit 104, and a command unit 105, which will be described below, based on various programs and data stored in the storage unit 130. In this way, the management device 3 manages the work of each device that makes up the production line 1a.

[0076] The storage unit 130 stores production plan information 131 , mounting information 132 , first suction nozzle information 133 , second suction nozzle information 134 , third suction nozzle information 135 , identification information 136 , and a matching result 231 .

[0077] The production plan information 131 is information created when formulating a production plan for the mounting system 1. For example, multiple production plans are defined for each planned production date set for a predetermined planning period (here, monthly). Each production plan specifies multiple board types to be produced. The production plan information 131 may also include second pickup nozzle information 134.

[0078] The mounting information 132 is data that is referenced during mounting work for the board types targeted in the production plan information 131, and includes board data indicating the size and type of each board type, mounting coordinate data indicating the component mounting positions on each board, and component data indicating the type of component to be mounted at each component mounting position.

[0079] The first suction nozzle information 133 is information relating to the suction nozzle 23 held by the component mounting device M5.

[0080] The second suction nozzle information 134 is information relating to the suction nozzle 23 required for future production.

[0081] The third suction nozzle information 135 is information relating to the type of suction nozzle 23 mounted on the nozzle changer 18 and the mounting position on the nozzle changer 18 .

[0082] The identification information 136 is information for identifying the nozzle changer 18 transported by the transport conveyor 11. For example, the identification information 136 is linked to the type of suction nozzle 23 mounted on the nozzle changer 18 and the mounting position on the nozzle changer 18.

[0083] The matching result 231 is a result of matching for the identification information 136. Details of the matching result 231 will be described later.

[0084] The acquiring unit 101 acquires first suction nozzle information 133 related to the suction nozzles 23 held by the component mounting device M5 and second suction nozzle information 134 related to the suction nozzles 23 required for future production. For example, the acquiring unit 101 may acquire the second suction nozzle information 134 from the production plan information 131. Alternatively, for example, the acquiring unit 101 may acquire the first suction nozzle information 133 from the component mounting device M5. The acquiring unit 101 stores the acquired first suction nozzle information 133 and second suction nozzle information 134 in the storage unit 130.

[0085] The identifying unit 102 identifies, from the second suction nozzle information 134, the suction nozzles 23 that are not included in the first suction nozzle information 133. Specifically, the identifying unit 102 identifies, from the suction nozzles 23 required for future production, the suction nozzles 23 that are not currently held by the component mounting device M5.

[0086] The determination unit 103 determines the mounting position of the suction nozzle 23 to be mounted on the nozzle changer 18. The method for determining the mounting position is not particularly limited, and may be determined, for example, based on a predetermined rule. The predetermined rule may be, for example, a rule that the suction nozzles 23 are mounted on the nozzle changer 18 starting from one end of the nozzle changer 18. The determination unit 103 may also determine the type of suction nozzle 23 to be mounted on the nozzle changer. The type of suction nozzle 23 to be determined is the type of suction nozzle 23 identified by the identification unit 102. In this way, the determination unit 103 determines which type of suction nozzle 23 should be mounted at which position on the nozzle changer 18. The determination unit 103 stores the type of suction nozzle 23 to be mounted on the nozzle changer 18 and the mounting position on the nozzle changer 18 in the storage unit 130 as third suction nozzle information 135.

[0087] The instructing unit 104 instructs a mounting operation to mount the identified suction nozzle 23 at the determined mounting position in the nozzle changer 18. For example, the instructing unit 104 issues the mounting instruction to a worker. If there are multiple suction nozzles 23 to be mounted, the instructing unit 104 instructs a mounting operation to mount the identified suction nozzle 23 at the determined mounting position for each of the multiple suction nozzles 23.

[0088] If the identification information included in the code 40 matches the identification information stored in the storage unit 230, the command unit 105 issues a command to the shutter drive mechanism 320 to move the shutter 42 to the open position. Details of the command unit 105 will be described later.

[0089] The operation / input unit 110 is an input device such as a touch panel or a keyboard, and performs input operations such as inputting operation commands and data to the management device 3.

[0090] The display unit 120 is a display device such as a liquid crystal panel, and displays a guide screen and various notification screens when an input operation is performed by the operation / input unit 110.

[0091] The communication unit 140 is a communication interface, and is connected to each device constituting the production line 1a via the network 2 to send and receive control signals and data. The communication unit 140 transmits mounting information 132, first suction nozzle information 133, second suction nozzle information 134, third suction nozzle information 135, and identification information 136 to the component mounting device M5. The communication unit 140 also receives a matching result 231 from the component mounting device M5. The communication unit 140 may also receive the first suction nozzle information 133 from the component mounting device M5.

[0092] Component mounting device M5 has a mounting control unit 200, a collating unit 210, a mounting head 13, a board camera 14, a notification unit 220, a memory unit 230, a communication unit 240, and a determination unit 250. Component mounting device M5 may also be integrated with a portion of the transport conveyor 11 (see FIG. 2). The mounting control unit 200, the collating unit 210, and the determination unit 250 are realized by a CPU device included in component mounting device M5 executing various programs and data stored in memory unit 130.

[0093] The mounting control unit 200 is an example of a control unit that controls the mounting head 13 to remove the suction nozzle 23 mounted on the nozzle changer 18 from the nozzle changer 18 based on the mounting position determined by the management device 3 (information included in the third suction nozzle information 135 stored in the storage unit 230). The mounting control unit 200 may also control the transport conveyor 11.

[0094] The board camera 14 reads the code 40 attached to the nozzle changer 18 that has been transported by the transport conveyor 11 to the component mounting device M5.

[0095] The matching unit 210 checks whether the identification information included in the code 40 matches the identification information 136 stored in the storage unit 230. If the identification information included in the code 40 matches the identification information 136 stored in the storage unit 230, the matching unit 210 stores in the storage unit 230 a matching result 231 indicating a match;

[0096] The notification unit 220 notifies of an error when the identification information included in the code 40 does not match the identification information 136 stored in the storage unit 230. The notification unit 220 may notify of the error by, for example, displaying an image or video on a display, outputting a voice or a buzzer sound from a speaker, or lighting or blinking a lamp.

[0097] The storage unit 230 stores the mounting information 132, the first suction nozzle information 133, the second suction nozzle information 134, the third suction nozzle information 135, the identification information 136, and the matching result 231. The mounting information 132, the first suction nozzle information 133, the second suction nozzle information 134, the third suction nozzle information 135, and the identification information 136 are information transmitted from the management device 3 and stored in the storage unit 230. In other words, this information is shared between the management device 3 and the component mounting device M5. Note that the first suction nozzle information 133 may be updated or newly created by the component mounting device M5. For example, the suction nozzle 23 held by the component mounting device M5 may be replaced by an operator, etc. In such a case, the state of the suction nozzle 23 in the first suction nozzle information 133 stored in the management device 3 may differ from the latest state of the suction nozzle 23 held by the component mounting device M5. In such a case, the component mounting device M5 may update or create the first suction nozzle information 133 and transmit it to the management device 3.

[0098] The communication unit 240 is a communication interface, and is connected to each device constituting the production line 1a and the management device 3 via the network 2 to send and receive control signals and data. The communication unit 240 receives mounting information 132, first suction nozzle information 133, second suction nozzle information 134, third suction nozzle information 135, and identification information 136 from the management device 3. The communication unit 140 also transmits the matching result 231 to the management device 3. The communication unit 240 may also transmit the first suction nozzle information 133 to the management device 3.

[0099] The determination unit 250 determines whether the type of suction nozzle 23 taken out from the nozzle changer 18 by the mounting head 13 is correct or not. Details of the determination unit 250 will be described later.

[0100] The nozzle changer 18 has a shutter control unit 300, a battery 310, a shutter 42, a shutter drive mechanism 320, and a communication unit 330. The shutter control unit 300 is realized by a CPU device (such as a microcomputer) included in the nozzle changer 18 executing various programs and data stored in a memory unit included in the nozzle changer 18.

[0101] The battery 310 supplies power to the shutter control unit 300 and the shutter drive mechanism 320 .

[0102] The shutter drive mechanism 320 is a mechanism for driving the shutter 42, and is configured by, for example, a motor.

[0103] The shutter control unit 300 controls the shutter drive mechanism 320. The shutter control unit 300 controls the shutter drive mechanism 320 in response to a command sent from the management device 3 to open or close the shutter 42.

[0104] The communication unit 330 is a communication interface, and is connected to the management device 3 via a wireless network to send and receive control signals and data. The communication unit 330 receives a command to open and close the shutter 42, which is sent from the management device 3.

[0105] Next, a supplying method according to the embodiment will be described with reference to FIG.

[0106] Fig. 8 is a flowchart showing a supplying method according to an embodiment. The supplying method is a method for supplying suction nozzles 23 to component mounting device M5, which mounts components on a board using suction nozzles 23 held by mounting head 13, and is executed by mounting system 1. For this reason, Fig. 8 and Figs. 9 and 10, which will be described later, are also flowcharts showing the operation of mounting system 1.

[0107] The determining unit 103 determines the mounting position of the suction nozzle 23 to be mounted on the nozzle changer 18 (step S11).

[0108] Next, the transfer conveyor 11 transfers the nozzle changer 18, in which the suction nozzle 23 has been mounted at the determined mounting position, to the component mounting device M5 (step S12).

[0109] Then, based on the determined mounting position, the mounting control unit 200 controls the mounting head 13 to remove the suction nozzle 23 mounted on the nozzle changer 18 from the nozzle changer 18 (step S13).

[0110] Next, the supply method according to the embodiment will be described in detail with reference to FIGS.

[0111] FIG. 9 is a flowchart showing an example of the operation up to mounting the suction nozzle 23 on the nozzle changer 18.

[0112] First, the acquisition unit 101 acquires the first suction nozzle information 133 relating to the suction nozzle 23 held by the component mounting device M5 (step S101).

[0113] Next, the acquisition unit 101 acquires the second suction nozzle information 134 relating to the suction nozzles 23 required for future production (step S102).

[0114] Then, the identifying unit 102 determines whether or not there is any suction nozzle 23 in the second suction nozzle information 134 that is not included in the first suction nozzle information 133 (step S103). In other words, the identifying unit 102 determines whether or not there is any suction nozzle 23 that is not currently held by the component mounting device M5 among the suction nozzles 23 required for future production.

[0115] If it is determined that there is no suction nozzle 23 in the second suction nozzle information 134 that is not included in the first suction nozzle information 133 (No in step S103), the process ends. In other words, in this case, the component mounting device M5 can perform future production using the suction nozzle 23 that it currently holds, and therefore the nozzle changer 18 is not transported to the component mounting device M5.

[0116] If it is determined that there is an suction nozzle 23 in the second suction nozzle information 134 that is not included in the first suction nozzle information 133 (Yes in step S103), the determination unit 103 determines the type, number, and mounting position of the suction nozzle 23 that needs to be mounted on the nozzle changer 18, and generates third suction nozzle information 135 that includes this information (step S104).

[0117] Furthermore, the determining unit 103 adds the identification information 136 of the nozzle changer 18 to be used (on which the specified suction nozzle 23 is to be mounted and which is to be transported to the component mounting device M5) to the third suction nozzle information 135 (step S105). For example, in the third suction nozzle information 135, the identification information 136 for identifying the nozzle changer 18 is linked to the mounting position on the nozzle changer 18 and the type of suction nozzle 23 to be mounted.

[0118] Next, the communication unit 140 transmits the third suction nozzle information 135 to the component mounting device M5 (step S106). As a result, the identification information for identifying the nozzle changer 18, the mounting position on the nozzle changer 18, the type of the suction nozzle 23 to be mounted, and the like are stored in the storage unit 230 of the component mounting device M5 in association with each other.

[0119] Next, the instruction unit 104 instructs an operator or the like to mount the suction nozzles 23 on the nozzle changer 18 (step S107). Specifically, the instruction unit 104 instructs the operator to mount the determined type and number of suction nozzles 23 on the determined mounting positions on the nozzle changer 18 to be used.

[0120] FIG. 10 is a flowchart showing an example of the operation when the suction nozzle 23 is supplied to the component mounting device M5.

[0121] The transport conveyor 11 receives the nozzle changer 18 with the determined type of suction nozzle mounted at the determined mounting position from upstream of the production line 1a (for example, the left side of Figure 1) and transports it to the component mounting device M5 (step S201).

[0122] Next, in the component mounting apparatus M5 located at the most upstream position, the board camera 14 of the component mounting apparatus M5 reads the code 40 attached to the nozzle changer 18, and the comparison unit 210 of the component mounting apparatus M5 checks whether the identification information included in the code 40 matches the identification information 136 stored in the memory unit 230 (step S202). Thus, by reading the code 40 attached to the nozzle changer 18 at the component mounting apparatus M5 located at the most upstream position among a plurality of component mounting apparatuses (e.g., component mounting apparatuses M5 and M6) arranged in a row, where the nozzle changer 18 being transported arrives first, it is possible to quickly determine whether the correct nozzle changer 18 that should be transported is being transported. Furthermore, the identification information 136 of the nozzle changer 18 that should be transported is stored in the memory unit 230, and by checking whether the identification information included in the code 40 attached to the transported nozzle changer 18 matches the identification information 136 stored in the memory unit 230, it is possible to determine whether the correct nozzle changer 18 that should be transported is being transported.

[0123] Next, the communication unit 240 transmits the comparison result 231 to the management device 3 (step S203). Note that the identification information included in the code 40 read by the board camera 14 may be transmitted to the management device 3, and the management device 3 may compare whether the identification information included in the code 40 matches the identification information 136 stored in the storage unit 130.

[0124] If the identification information included in the code 40 does not match the stored identification information 136 (No in step S204), the notification unit 220 notifies an error (step S205). This makes it possible to notify that the correct nozzle changer 18 that should have been transported has not been transported.

[0125] If the identification information included in the code 40 matches the stored identification information 136 (Yes in step S204), the command unit 105 issues a command to the shutter drive mechanism 320 to move the shutter 42 to the open position, and the shutter drive mechanism 320 moves the shutter 42 from the closed position to the open position, that is, opens the shutter 42 of the nozzle changer 18 (step S206). Specifically, upon receiving the command, the shutter drive mechanism 320 uses power supplied from the battery 310 to move the shutter 42 from the closed position to the open position. This allows the shutter 42 to be automatically moved from the closed position to the open position.

[0126] Next, the mounting control unit 200 controls the mounting head 13 to remove the suction nozzle 23 mounted on the nozzle changer 18 from the nozzle changer 18 based on the determined type and the determined mounting position (specifically, the type and mounting position linked to the identification information 136), thereby supplying the suction nozzle 23 to the component mounting device M5 (step S207). For example, the mounting control unit 200 places the suction nozzle 23 originally attached to the mounting head 13 and not to be used in the next production run in an empty space in the nozzle changer 18 (for example, a nozzle insertion hole 41H into which the suction nozzle 23 has not been inserted) or an empty space on the nozzle exchange table 16, and then attaches the suction nozzle 23 mounted on the nozzle changer 18 to be used in the next production run to the mounting head 13, thereby replacing the suction nozzle 23.

[0127] The determination unit 250 can determine whether the suction nozzle 23 supplied to the component mounting device M5 is of the correct type because the third suction nozzle information 135 stored in the memory unit 230 includes information about the type of suction nozzle 23 and the type of suction nozzle 23 to be supplied to the component mounting device M5 is known. For example, the determination unit 250 may determine whether the type of suction nozzle 23 removed from the nozzle changer 18 by the mounting head 13 is correct based on an image obtained by capturing the suction nozzle 23 held by the mounting head 13. For example, the image is an image obtained by capturing an image of the entire mounting head 13 from the bottom side (the negative side of the Z axis in FIG. 3 ) using the component camera 15. This determination can also be performed using image recognition processing or the like. If the type of suction nozzle 23 included in the captured image is different from the type of suction nozzle 23 to be supplied to the component mounting device M5, it can be determined that the suction nozzle 23 supplied to the component mounting device M5 is the wrong type. Alternatively, the determination unit 250 may determine whether the type of suction nozzle 23 taken out from the nozzle changer 18 by the mounting head 13 is correct based on the flow rate (air flow rate) of the suction nozzle 23 held by the mounting head 13. The flow rate of the suction nozzle 23 may be the flow rate during either suction or blowing. For example, if the flow rate of the suction nozzle 23 held by the mounting head 13 differs from the flow rate of the suction nozzle 23 to be supplied to the component mounting device M5, it can be determined that the suction nozzle 23 supplied to the component mounting device M5 is the wrong type.

[0128] After the suction nozzle 23 has completed supplying the component to the component mounting device M5, the communication unit 240 transmits to the management device 3 a message indicating that the suction nozzle 23 has completed supplying the component to the component mounting device M5 (step S208).

[0129] Next, the command unit 105 issues a command to the shutter drive mechanism 320 to move the shutter 42 to the closed position, and the shutter drive mechanism 320 moves the shutter 42 from the open position to the closed position, that is, closes the shutter 42 of the nozzle changer 18 (step S209). As a result, the shutter 42 is closed except when the suction nozzle 23 is supplying a component to the component mounting device M5, and it is possible to prevent the suction nozzle 23 from falling off the nozzle changer 18.

[0130] Then, the transport conveyor 11 transports the nozzle changer 18 to the downstream component mounting device M6 (step S210). By performing the processes from step S201 to step S210 for each of the component mounting devices, the mounting control unit 200 of each of the component mounting devices controls its mounting head 13 to remove the suction nozzle 23 from the nozzle changer 18.

[0131] As described above, the mounting positions of the suction nozzles 23 are determined in advance, for example, during off-site setup before the nozzle changer 18 is transported, and then the nozzle changer 18 is transported and the suction nozzles 23 are removed based on the determined mounting positions, so there is no need to identify the mounting positions of the suction nozzles 23 by taking images of the suction nozzles 23 one by one with a camera, which can improve work efficiency when supplying the suction nozzles 23. Furthermore, when determining whether the type of the removed suction nozzle 23 is correct, the type and mounting positions of the suction nozzles 23 are determined in advance, for example, during off-site setup, and then the nozzle changer 18 is transported and the suction nozzles 23 are removed based on the determined type and mounting positions, so there is no need to identify the type and mounting positions of the suction nozzles 23 by taking images of the suction nozzles 23 one by one with a camera, which can improve work efficiency when supplying the suction nozzles 23.

[0132] (Other embodiments) The supply method and mounting system 1 of the present disclosure have been described above based on the embodiments, but the present disclosure is not limited to the above-described embodiments. As long as they do not deviate from the spirit of the present disclosure, various modifications conceivable by those skilled in the art to the present embodiments and forms constructed by combining components of different embodiments are also included within the scope of the present disclosure.

[0133] For example, in the above embodiment, an example has been described in which the identification information included in the code 40 attached to the nozzle changer 18 is compared to the identification information 136 stored in the storage unit 230 to determine whether they match. However, the comparison need not be performed. In this case, the identification information for identifying the nozzle changer 18 may not be stored in the storage unit 130 or 230. Furthermore, the component mounting device M5 may not have the comparison unit 210 and the notification unit 220.

[0134] For example, in the above embodiment, the nozzle changer 18 has been described as having the shutter 42, the shutter control unit 300, the battery 310, and the shutter drive mechanism 320, but these components may not be included. In this case, the management device 3 (control unit 100) may not have the command unit 105.

[0135] For example, in the above embodiment, an example has been described in which a plurality of component mounting devices are provided on the production line 1a, but only one component mounting device may be provided.

[0136] For example, in the above embodiment, an example has been described in which the type of suction nozzle 23 to be mounted on the nozzle changer 18 and the mounting position on the nozzle changer 18 are determined, but the type of suction nozzle 23 does not have to be determined. In this case, the component mounting device M5 does not need to have the determination unit 250.

[0137] For example, the steps in the supply method may be executed by a computer (computer system). The present disclosure can be realized as a program for causing a computer to execute the steps included in the supply method. Furthermore, the present disclosure can be realized as a non-transitory computer-readable recording medium, such as a CD-ROM, on which the program is recorded.

[0138] For example, when the present disclosure is realized as a program (software), each step is performed by running the program using hardware resources such as a computer's CPU, memory, input / output circuits, etc. In other words, each step is performed by the CPU acquiring data from memory or input / output circuits, etc., performing calculations, and outputting the calculation results to memory or input / output circuits, etc.

[0139] Furthermore, each of the components included in the mounting system 1 of the above-described embodiment may be realized as a dedicated or general-purpose circuit.

[0140] Furthermore, each of the components included in the mounting system 1 of the above-described embodiment may be realized as an LSI (Large Scale Integration) which is an integrated circuit (IC).

[0141] Furthermore, the integrated circuit is not limited to an LSI, but may be realized by a dedicated circuit or a general-purpose processor. A programmable FPGA (Field Programmable Gate Array) or a reconfigurable processor, in which the connections and settings of circuit cells within the LSI can be reconfigured, may also be used.

[0142] Furthermore, if an integrated circuit technology that can replace LSI emerges due to advances in semiconductor technology or other derivative technologies, it is natural that each component included in the mounting system 1 may be integrated using that technology.

[0143] In addition, this disclosure also includes forms obtained by making various modifications to the embodiments that a person skilled in the art would think of, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope of the present disclosure.
