[0003] [Patent Document 1] International Publication No. 2018 / 127956 Summary of the Invention [Problem to be solved by the invention]

[0004] In a component mounting device, it is sometimes necessary to replace a feeder that supplies components. When replacing a feeder, the feeder may be attached or detached from a slot in the component mounting device. In a component mounting device with multiple slots, if feeders are attached to the slots without consideration, a deviation in the number of times the feeders are attached among the multiple slots may occur. Therefore, this specification provides a technology that can quickly perform the task of removing components from component feeders attached to feeder attachment units and mounting them on a board while leveling out the number of times component feeders are attached for multiple feeder attachment units. [Means for solving the problem]

[0005] The management system disclosed in this specification is a management system for a mounting device that mounts components on a board, the mounting device having a plurality of feeder mounting units capable of mounting component feeders that supply components for mounting, and configured to remove components from the component feeders mounted on the feeder mounting units and mount them on the board. The management system includes a first recognition unit that recognizes, for each of the plurality of feeder mounting units, the number of times the component feeder has been mounted, a second recognition unit that recognizes, for each of the plurality of feeder mounting units, a cycle time for removing components from the component feeders mounted on the feeder mounting unit and mounting them on the board, and a selection unit that, when the number of times recognized by the first recognition unit is equal to or greater than a predetermined reference number for all of the plurality of feeder mounting units, selects from the plurality of feeder mounting units the feeder mounting unit that has been recognized the fewest number of times by the first recognition unit and has the shortest cycle time recognized by the second recognition unit.

[0006] This configuration allows the number of times that component feeders are attached to multiple feeder attachment units to be equalized, and when a component feeder is attached to a feeder attachment unit selected by the selection unit, the work of removing components from the component feeder and mounting them on a board can be performed quickly.

[0008] The main features of the embodiments described below are listed below. Note that the technical elements described below are independent technical elements that exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.

[0009] In one embodiment of the present technology, if there is a feeder mounting unit among the multiple feeder mounting units that is recognized by the first recognition unit less than the reference number of times, the selection unit may select the feeder mounting unit that is recognized by the first recognition unit less than the reference number of times and has the shortest cycle time recognized by the second recognition unit.

[0010] In one embodiment of the present technology, the selection unit may identify the feeder mounting unit among the multiple feeder mounting units that has the shortest cycle time recognized by the second recognition unit, and if the number of times the identified feeder mounting unit is recognized by the first recognition unit is less than the reference number of times, select the identified feeder mounting unit.

[0011] The mounting device may further include a connector for each of the plurality of feeder mounting sections, which electrically connects the feeder mounting section to the mounted component feeder when the component feeder is mounted on the feeder mounting section.

[0012] The management system may further include an acquisition unit that acquires specified information from a component feeder in response to the component feeder being attached to the feeder attachment unit, and a counting unit that counts up the number of times a component feeder has been attached to the feeder attachment unit in response to the acquisition unit acquiring the specified information.

[0013] The management system may further include an exchange device that mounts a component feeder on the feeder mounting unit selected by the selection unit. [Example]

[0014] (Example) A management system 2 according to an embodiment will be described with reference to the drawings. As shown in FIGS. 1 and 2, the management system 2 according to the embodiment includes a management computer 200, a mounting device 10, and an exchange device 100. The management computer 200 includes, for example, a CPU and memory (both not shown), and executes various controls and processes related to the management system 2. The mounting device 10 is a device that mounts electronic components 4, such as IC chips, on a circuit board 8, such as a printed circuit board. The mounting device 10 is also called a chip mounter. The exchange device 100 is a device that exchanges component feeders 30 by attaching and detaching the component feeders 30 to and from the mounting device 10. The exchange device 100 is also called a smart loader.

[0015] The mounting apparatus 10 will now be described in more detail. The mounting apparatus 10 includes a board conveyor 12, a plurality of component feeders 30, a feeder holder 14, a mounting head 16, a head moving device 18, and a display / operation unit 20.

[0016] The board conveyor 12 carries in, positions, and carries out the circuit boards 8. As an example, the board conveyor 12 has a pair of belt conveyors and a support device (not shown) that supports the circuit boards 8 from below.

[0017] Each component feeder 30 stores a plurality of electronic components 4 to be mounted on a board. Each component feeder 30 is detachably attached to the feeder holder 14 and supplies the electronic components 4 to the mounting head 16. The specific configuration of the component feeders 30 is not particularly limited. Each component feeder 30 may be, for example, a tape feeder that supplies a plurality of electronic components 4 stored on a tape, a tray feeder that supplies a plurality of electronic components 4 stored on a tray, or a bulk feeder that supplies a plurality of electronic components 4 stored randomly in a container.

[0018] As shown in FIG. 3, the feeder holding unit 14 has a plurality of (for example, N (N is an integer of 2 or more)) slots ST (ST1, ST2, ..., STN), and a component feeder 30 can be removably attached to each of the plurality of slots ST. The component feeder 30 is set in the mounting apparatus 10 by being inserted into the slot ST. The feeder holding unit 14 may be fixed to the mounting apparatus 10, or may be removably attached to the mounting apparatus 10.

[0019] As shown in FIG. 4 , the component feeder 30 is provided with a connector 32 for power supply and communication. The slot ST of the feeder holder 14 is also provided with a connector 22 for power supply and communication. When the component feeder 30 is attached to the slot ST of the feeder holder 14, the connector 32 of the component feeder 30 connects to the connector 22 of the slot ST. This electrically connects the component feeder 30 and the slot ST via the connectors 32 and 22. The connector 32 of the component feeder 30 protrudes toward the slot ST when the component feeder 30 is attached to the slot ST. The connector 22 of the slot ST protrudes toward the component feeder 30. The connectors 32 and 22 each include, for example, multiple pins and sockets. Power is supplied / received and information is transmitted / received via the connectors 32 and 22.

[0020] As shown in FIG. 1 , the mounting head 16 of the mounting apparatus 10 has a nozzle 6 that picks up an electronic component 4. The nozzle 6 is detachably attached to the mounting head 16. The mounting head 16 is capable of moving the nozzle 6 in the Z direction (here, the vertical direction) to move the nozzle 6 toward and away from a component feeder 30 and a circuit board 8. The mounting head 16 can pick up an electronic component 4 from the component feeder 30 using the nozzle 6, and can mount the electronic component 4 picked up by the nozzle 6 on the circuit board 8. Note that the mounting head 16 is not limited to having a single nozzle 6, and may have multiple nozzles 6.

[0021] The head moving device 18 moves the mounting head 16 between the component feeder 30 and the circuit board 8. As an example, the head moving device 18 is an XY robot that moves a moving base 19 in the X and Y directions, and the mounting head 16 is fixed to the moving base 19. Note that the mounting head 16 does not have to be fixed to the moving base 19, and may be detachably attached to the moving base 19.

[0022] The display operation unit 20 is configured by, for example, a touch panel. The display operation unit 20 displays, for example, various information related to the mounting device 10. The display operation unit 20 also accepts, for example, various operations related to the mounting device 10.

[0023] FIG. 5 is a block diagram of the management system 2. Not all of the components of the management system 2 are shown in FIG. 5, and some components are omitted. As shown in FIG. 5, the mounting device 10 in the management system 2 includes a communication I / F 24 and a control unit 50. The communication I / F 24 of the mounting device 10 is connected to the management computer 200 via a network 90, and performs wired and / or wireless communication with the management computer 200. The mounting device 10 is configured to be able to send and receive information via the communication I / F 24.

[0024] The control unit 50 of the mounting apparatus 10 includes a CPU (not shown) and a storage unit 52 (e.g., ROM or RAM). The control unit 50 executes various controls and processes related to the mounting apparatus 10 in accordance with predetermined programs stored in the storage unit 52. For example, the control unit 50 controls the operations of the board conveyor 12, the feeder holder 14, the mounting head 16, the head moving device 18, the display operation unit 20, etc. (see FIGS. 1 and 2).

[0025] The storage unit 52 of the mounting apparatus 10 stores a table 54 containing information on the number of times of placement and cycle time information for multiple slots ST (see FIGS. 3 and 4) of the feeder holder 14. FIG. 6 is a diagram showing the table 54 according to an embodiment. As shown in FIG. 6, the placement number information included in the table 54 indicates the number of times a component feeder 30 has been placed in a slot ST of the mounting apparatus 10 (hereinafter, sometimes referred to as the "feeder placement number"). In Case 1, which is assumed as an example, the number of times a component feeder 30 has been placed in slot ST1 is "9 times," and the number of times a component feeder 30 has been placed in slot ST2 is "8 times." The feeder placement number is counted up each time a component feeder 30 is placed in slot ST. For example, when a component feeder 30 is placed in slot ST1, the control unit 50 counts up the feeder placement number for slot ST1. This increases the feeder placement number for slot ST1 by one.

[0026] As shown in Fig. 5, the component feeder 30 includes a control unit 60 that controls the operation of the component feeder 30. The control unit 60 includes a CPU (not shown) and a memory unit 62 (e.g., ROM or RAM). The control unit 60 executes various controls and processes related to the component feeder 30 in accordance with predetermined programs stored in the memory unit 62. For example, the control unit 60 controls the rotation of a motor (not shown) of the component feeder 30. The memory unit 62 of the component feeder 30 also stores identification information for identifying the component feeder 30.

[0027] When the component feeder 30 is attached to the slot ST of the mounting apparatus 10, the connector 32 of the component feeder 30 is connected to the connector 22 of the mounting apparatus 10 (see FIG. 4). In response to the connection of the connectors 22, 32, the control unit 50 of the mounting apparatus 10 (see FIG. 5) acquires the identification information stored in the memory unit 62 of the component feeder 30. In response to acquiring the identification information of the component feeder 30, the control unit 50 counts up the number of feeder attachments for the slot ST into which the component feeder 30 is attached.

[0028] Next, the cycle time information will be described. The cycle time information included in table 54 indicates the cycle time of a process in which, when a component feeder 30 is attached to a slot ST (e.g., ST1), electronic components 4 are removed from the component feeder 30 and mounted on a circuit board 8. As shown in FIG. 7, the cycle time in this embodiment is the time required for operations including the process of loading the circuit board 8 (S2), the process of suctioning the electronic components 4 (S4), the process of mounting the electronic components 4 on the circuit board 8 (S6), and the process of unloading the circuit board 8 (S8). For each of the multiple slots ST, control unit 50 calculates the cycle time assuming a situation in which electronic components 4 are removed from the component feeder 30 attached to the slot ST and mounted on the circuit board 8. As shown in FIG. 6, in Case 1, which is assumed as an example, the cycle time for slot ST1 is "1 second," and the cycle time for slot ST2 is "2 seconds." The control unit 50 calculates the cycle time based on, for example, sequence information, time chart information, etc. for mounting the electronic components 4 on the circuit board 8. Note that the method for calculating the cycle time is not particularly limited.

[0029] Next, the exchange device 100 will be described. As shown in Figures 1 and 2, the exchange device 100 holds a plurality of component feeders 30 for replacement to be attached to the feeder holding unit 14 of the mounting device 10. The exchange device 100 can attach or detach the component feeders 30 to or from the slots ST (see Figures 3 and 4) of the feeder holding unit 14. The exchange device 100 is configured to be movable back and forth and left and right relative to the mounting device 10.

[0030] 5, the exchange device 100 includes a communication I / F 84 and a control unit 80. The communication I / F 84 of the exchange device 100 is connected to a management computer 200 via a network 90, and performs wired and / or wireless communication with the management computer 200. The exchange device 100 is configured to be able to send and receive information via the communication I / F 84.

[0031] The control unit 80 of the exchange device 100 includes a CPU (not shown) and a storage unit 82 (e.g., ROM or RAM). The control unit 80 executes various controls and processes related to the exchange device 100 in accordance with a predetermined program stored in the storage unit 82.

[0032] The memory unit 82 of the exchange device 100 stores slot position information for identifying the positions of multiple slots ST (ST1, ST2, ..., STN) of the mounting device 10. The control unit 80 identifies the position of each slot ST (e.g., ST1) based on the slot position information stored in the memory unit 82. The exchange device 100 can attach a component feeder 30 to the slot ST identified based on the slot position information.

[0033] (Slot selection process; Figure 8) Next, the slot selection process of the embodiment will be described. The slot selection process starts, for example, when the power of the mounting apparatus 10 is turned on. As shown in FIG. 8, in S10 of the slot selection process, the control unit 50 of the mounting apparatus 10 recognizes the feeder mounting count, which is the number of times a component feeder 30 has been mounted, for each of multiple slots ST (e.g., N slots ST1, ST2, ..., STN). The control unit 50 recognizes the feeder mounting count based on the mounting count information stored in the memory unit 52 (see FIGS. 5 and 6).

[0034] In the next step S12, the control unit 50 recognizes the cycle time for removing electronic components 4 from the component feeders 30 attached to each of the slots ST (ST1, ST2, ..., STN) and mounting the electronic components 4 on the circuit board 8. The control unit 50 recognizes the cycle time based on the cycle time information stored in the memory unit 52 (see FIGS. 5 and 6).

[0035] In the next step S14, the control unit 50 identifies the shortest cycle time among the cycle times for each of the multiple slots ST recognized in S12, and identifies the slot ST (e.g., ST1) with that cycle time (i.e., the shortest cycle time). Hereinafter, the slot ST identified by the control unit 50 in S14 will be referred to as the first shortest slot for convenience.

[0036] In the next S16, the control unit 50 recognizes the number of times the feeder has been attached to the first shortest slot identified in S14, and determines whether the number of times the feeder has been attached is less than a predetermined reference number R (e.g., 10 times). The number of times the feeder has been attached to the first shortest slot is recognized based on attachment number information (see FIG. 6) stored in the memory unit 52. The predetermined reference number R is set, for example, taking into consideration the need for maintenance of the connector 22 of the slot ST. If the number of times the feeder has been attached exceeds the reference number R, it is desirable to consider maintenance of the connector 22. If the number of times the feeder has been attached to the first shortest slot is less than the reference number R (YES), the process proceeds to S18. If the number of times the feeder has been attached to the first shortest slot is equal to or greater than the reference number R (NO), the process proceeds to S20.

[0037] In S18 after YES in S16, the control unit 50 selects the first shortest slot as the slot ST for mounting the component feeder 30.

[0038] In S20 after NO in S16, the control unit 50 determines whether or not there is a slot ST other than the first shortest slot among the multiple slots ST, the slot ST having a feeder installation count less than the reference count R. If there is a slot ST other than the first shortest slot, the slot ST having a feeder installation count less than the reference count R (YES), the process proceeds to S22. If there is no slot ST other than the first shortest slot, the slot ST having a feeder installation count less than the reference count R (NO), the process proceeds to S24. In other words, if the feeder installation count for all of the multiple slots ST is equal to or greater than the reference count R, the process proceeds to S24.

[0039] In S22 after YES in S20, the control unit 50 selects the slot ST with the shortest cycle time from among the multiple slots ST whose feeder placement count is less than the reference count R. More specifically, the control unit 50 recognizes the cycle time for each of the multiple slots ST whose feeder placement count is less than the reference count R. Next, the control unit 50 identifies the shortest cycle time from among the multiple identified cycle times, and identifies the slot ST with that cycle time (i.e., the shortest cycle time). The control unit 50 then selects the identified slot ST as the slot ST for placing the component feeder 30. Hereinafter, the slot ST selected by the control unit 50 in S22 will be referred to as the second shortest slot for convenience. Note that if there is only one slot ST for which YES is determined in S20 above, that slot ST becomes the second shortest slot.

[0040] In S24 after NO in S20 above, the control unit 50 selects the slot ST with the fewest feeder placement counts and the shortest cycle time from among all of the multiple slots ST (i.e., N slots ST). More specifically, the control unit 50 identifies the slot ST with the fewest feeder placement counts from among the multiple (N) slots ST recognized in S10 above, and identifies the slot ST with that feeder placement count (i.e., the fewest feeder placement count). If there are multiple slots ST with the fewest feeder placement counts, the control unit 50 identifies the shortest cycle time from among the cycle times for each of those slots ST, and identifies the slot ST with that cycle time (i.e., the shortest cycle time). The control unit 50 selects the identified slot ST as the slot ST for placing the component feeder 30. Hereinafter, the slot ST selected by the control unit 50 in S24 will be referred to as the third shortest slot for convenience.

[0041] In S26, the control unit 50 transmits information on the selection results made in S18, S22, or S24 to the exchange device 100 via the management computer 200. In a modified example, the control unit 50 may transmit the information on the selection results directly to the exchange device 100 without going through the management computer 200. The control unit 50 may also display the information on the selection results on the display operation unit 20.

[0042] Based on the information on the selection result received from the mounting device 10, the exchange device 100 mounts the component feeder 30 in the slot ST selected in S18, S22, or S24 above.

[0043] (Case 1; Figure 6) Next, a specific case realized by the above-described management system 2 will be described. In Case 1 shown in Fig. 6, the control unit 50 identifies slot ST1 as the first shortest slot in S14 of the slot selection process (see Fig. 8). Because the number of feeder mounting times (9 times) of slot ST1 is less than the reference number R (10 times), the control unit 50 selects slot ST1 as the slot ST for mounting the component feeder 30 (YES in S16, S18).

[0044] (Case 2; Figure 9) 9, the feeder placement count (10 times) of slot ST1 (first shortest slot) identified in S14 is equal to or greater than the reference count R (10 times). Also, there are slots ST (ST2, ST3, ..., STN) other than slot ST1 (first shortest slot) whose feeder placement count is less than the reference count R (10 times). Of the slots ST (ST2, ST3, ..., STN) whose feeder placement count is less than the reference count R (10 times), slot ST2 has the shortest cycle time, so the control unit 50 selects slot ST2 (second shortest slot) as the slot ST for placing the component feeder 30 (NO in S16, YES in S20, S22).

[0045] (Cases 3 and 4; Figure 9) 9, there is no slot ST other than slot ST1 (first shortest slot) for which the number of feeder placements is less than the reference number R (10 times). That is, the number of feeder placements for all slots ST (ST1, ST2, ..., STN) is equal to or greater than the reference number R (10 times). Of all slots ST (ST1, ST2, ..., STN), slot ST1 has the fewest number of feeder placements and the shortest cycle time, so control unit 50 selects slot ST1 (third shortest slot) as the slot ST for placing component feeder 30 (NO in S20, S24).

[0046] In case 4 shown in Figure 9, among all slots ST (ST1, ST2, ..., STN), slot ST2 is the slot ST with the fewest feeder mounting counts and the shortest cycle time, so the control unit 50 selects slot ST2 (the third shortest slot) as the slot ST for mounting the component feeder 30 (NO in S20, S24).

[0047] (effect) The management system 2 of the embodiment has been described above. As described above, in the management system 2 of the embodiment, the control unit 50 recognizes the number of times that the component feeders 30 have been placed (feeder placement count) for each of the multiple slots ST (ST1, ST2, ..., STN) (S10 in FIG. 8). The control unit 50 also recognizes the cycle time for removing electronic components 4 from the component feeders 30 placed in the slot ST and mounting them on the circuit board 8 for each of the multiple slots ST (S12). If the feeder placement count for all of the multiple slots ST is equal to or greater than a predetermined reference count R (e.g., 10 times), the control unit 50 selects the slot ST with the fewest feeder placement count and the shortest cycle time from the multiple slots ST (NO in S16, NO in S20, S24).

[0048] This configuration allows the number of feeder mounting operations to be equalized for multiple slots ST. Also, when a component feeder 30 is mounted in a selected slot ST, the electronic components 4 can be quickly removed from the component feeder 30 and mounted on the circuit board 8.

[0049] Furthermore, if there is a slot ST among the multiple slots ST whose feeder mounting count is less than the reference count R, the control unit 50 selects the slot ST whose feeder mounting count is less than the reference count R and whose cycle time is shortest (YES in S20, S22 in FIG. 8). This configuration allows the work of picking up electronic components 4 from component feeders 30 and mounting them on circuit boards 8 to be carried out quickly.

[0050] Furthermore, the control unit 50 identifies the slot ST with the shortest cycle time among the multiple slots ST (ST1, ST2, ..., STN), and selects the identified slot ST if the number of feeder mounting times for the identified slot ST is less than the reference number R (YES in S14 and S16, S18 in FIG. 8). This configuration allows the work of removing electronic components 4 from component feeders 30 and mounting them on circuit boards 8 to be performed quickly.

[0051] The mounting device 10 is provided with a connector 22 for each of the multiple slots ST, which electrically connects the slot ST to the component feeder 30 when the component feeder 30 is installed in the slot ST. When component feeders 30 are repeatedly installed in the slot ST, it is conceivable that the connector 22 will deteriorate as the number of times the feeder is installed increases. With the above configuration, the number of times the feeder is installed can be leveled out, and therefore the degree of deterioration of the connector 22 can be leveled out for the multiple slots ST.

[0052] In addition, in the management system 2, the control unit 50 acquires identification information from the component feeder 30 in response to the component feeder 30 being attached to the slot ST. Furthermore, in response to acquiring the identification information of the component feeder 30, the control unit 50 counts up the number of feeder attachments for the slot ST in which the component feeder 30 is attached. With this configuration, the number of feeder attachments can be reliably counted up when the component feeder 30 is attached to the slot ST.

[0053] The management system 2 includes an exchange device 100 that mounts a component feeder 30 in a slot ST selected by the control unit 50. This configuration ensures that the component feeder 30 is reliably mounted in a slot ST that requires fewer feeder mounting times and has a short cycle time.

[0054] (Correspondence) The slot ST is an example of a "feeder mounting unit." The process of S10 of the slot selection process is an example of a process executed by a "first recognition unit." The process of S12 is an example of a process executed by a "second recognition unit." The processes of S14, S16, S18, S20, S22, and S24 are each an example of a process executed by a "selection unit." The identification information of the component feeder 30 is an example of "predetermined information." The process of acquiring the identification information is an example of a process executed by an "acquisition unit." The process of counting up the number of times the feeder has been mounted is an example of a process executed by a "counting unit."

[0055] (Variation) (1) The slot selection process (see FIG. 8) may be executed by the management computer 200. There is no particular limitation on the entity that executes the information processing.

[0056] (2) If the slot ST selected in the process of S18, S22, or S24 of the slot selection process (see FIG. 8) is in an unusable state, the management computer 200 may transmit unusable information indicating that the slot ST is unusable to the mounting device 10. In this case, the control unit 50 of the mounting device 10 may execute the slot selection process again for the slots ST other than the unusable slot ST.
