[0003] [Patent Document 1] JP 2011-228414 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Document 1, the component information storage unit can only store two pieces of information: first component information about the component currently being used, and second component information about the component that is on the tape reel side of the currently being used component. Therefore, when another carrier tape is spliced ​​to the component that is on the tape reel side, the second component information stored in the component information storage unit may be overwritten with the component information about this other carrier tape, resulting in a problem of insufficient management of the carrier tape being used.

[0005] Therefore, the present disclosure provides a component mounting system etc. that is capable of adequately managing carrier tapes even when three or more carrier tapes are joined together by splicing. [Means for solving the problem]

[0006] A component mounting system according to one embodiment of the present disclosure includes a tape feeder that supplies components by unwinding a tape that contains a plurality of components, and a component mounting device that takes out the components supplied by the tape feeder and mounts them on a board, and is equipped with a tape usage information storage unit that stores information about a leading tape currently being used by the component mounting device, and a control unit that, when the leading end of the leading tape is joined to the leading edge of a first following tape, causes information about the first following tape to be stored in the tape usage information storage unit in addition to the information about the leading tape, and that, when the leading edge of a second following tape is joined to the leading end of the first following tape, causes information about the second following tape to be stored in the tape usage information storage unit in addition to the information about the leading tape and the information about the first following tape. Effect of the Invention

[0007] According to the component mounting system etc. of the present disclosure, it is possible to adequately manage the carrier tapes even when three or more carrier tapes are joined together by splicing.

[0015] As shown in FIGS. 1 and 2, component mounting system 1 has a function of mounting components (electronic components) on a board to produce a mounted board, and has functions of supplying, delivering, and collecting the boards to be mounted.

[0016] The component mounting system 1 includes a component mounting line, a tape feeder 8, and a management device 3.

[0017] The component mounting line has a function of mounting components on a board to manufacture a mounted board. The component mounting line is a production device configured by connecting multiple electronic component mounting devices, namely, a solder printing device M1, component mounting devices M2 to M4, and a reflow device M5, in series in this order. Each device from the solder printing device M1 to the reflow device M5 is connected by a communication network 2, and the entire device is controlled by a management device 3. The solder printing device M1 screen-prints a paste-like solder on electrodes for component bonding formed on the board. The component mounting devices M2 to M4 perform a component mounting operation of taking out components supplied by a tape feeder 8 arranged in a component supply unit 7 and mounting them on the board. The reflow device M5 melts the solder to solder-bond the component terminals mounted on the board to the electrodes of the board.

[0018] Next, the component mounting apparatuses M2 to M4 will be described with reference to FIGS.

[0019] As shown in Figures 2 and 3, component mounting devices M2 to M4 of this embodiment include a base 4, a board transport unit 5, a component supply unit 7, a Y-axis moving table 10, an X-axis moving table 11, a mounting head 12, a component recognition camera 9, and a board recognition camera 14.

[0020] The base 4 is capable of arranging a substrate 6, a substrate transport unit 5, etc. The base 4 is provided with the substrate transport unit 5 on its upper surface, which extends along the X-axis direction.

[0021] The board transport unit 5 transports the board 6 delivered from an upstream device, thereby positioning and holding the board 6 at a mounting work position. Component supply units 7 are arranged on both sides of the board transport unit 5 in the Y-axis direction.

[0022] The component supply unit 7 is a structure for the mounting head 12 to take out components, in other words, for supplying components to the mounting head 12. A plurality of tape feeders 8 are attached in parallel to the component supply unit 7. The tape feeders 8 pitch-feed a carrier tape 17, which is a container that contains components, so that the mounting head 12 constituting the component mounting mechanism 13 can position (supply) the components at the mounting position. The carrier tape 17 is included in the tape.

[0023] A long Y-axis moving table 10 is disposed substantially horizontally along the Y-axis at one end in the positive direction of the upper surface of the base 4. A pair of long X-axis moving tables 11 are mounted on the Y-axis moving table 10 so as to be slidable along the Y-axis direction.

[0024] One of the pair of X-axis moving tables 11 is disposed on the positive Y-axis side relative to the substrate transport section 5, and the other of the pair of X-axis moving tables 11 is disposed on the negative Y-axis side relative to the substrate transport section 5. The pair of X-axis moving tables 11 are also disposed approximately horizontally along the X-axis direction.

[0025] The pair of X-axis moving tables 11 can be moved in the Y-axis direction by a linear drive mechanism of the Y-axis moving table 10. A mounting head 12 is slidably attached to each of the pair of X-axis moving tables 11.

[0026] The mounting head 12 is a multiple head equipped with multiple holding heads, and a suction nozzle 12a is attached to the lower end of each holding head 12b, which can suck and hold a component and move up and down individually. In addition, the mounting head 12 can move along the X-axis direction by a linear drive mechanism of the X-axis moving table 11.

[0027] The linear drive mechanism drives the Y-axis moving table 10 and the X-axis moving table 11, allowing the mounting head 12 to move freely in the XY plane. This allows the mounting head 12 to suck and pick up components from the tape feeders 8 arranged in each component supply unit 7 using multiple suction nozzles 12a, move above the board 6, and mount the components at the mounting positions on the board 6. The Y-axis moving table 10, the X-axis moving table 11, and the mounting head 12 constitute a component mounting mechanism 13.

[0028] Furthermore, on the base 4, a component recognition camera 9 is disposed between the board transport unit 5 and each component supply unit 7. When the mounting head 12 which has taken out a component from the component supply unit 7 passes above the component recognition camera 9, the component recognition camera 9 captures an image of the component held by a predetermined suction nozzle 12a out of the multiple suction nozzles 12a attached to the mounting head 12 at the imaging timing when the mounting head 12 passes by. Therefore, the component recognition camera 9 can recognize the component that has been picked up by a predetermined suction nozzle 12a out of the multiple suction nozzles 12a.

[0029] Furthermore, when the component recognition camera 9 recognizes the component picked up by the suction nozzle 12a and the tip of the suction nozzle 12a, the component recognition camera 9 recognizes the component under a first illumination condition, and recognizes the tip under a second illumination condition different from the first illumination condition. In other words, the component recognition camera 9 can control the light emission of the illumination unit that illuminates the component and the tip of the suction nozzle 12a, based on the imaging timing.

[0030] A board recognition camera 14 is disposed on the coupling plate to which the mounting head 12 is attached, the board recognition camera 14 being located on the underside of the X-axis moving table 11 and moving integrally with the mounting head 12. The board recognition camera 14 is disposed on the coupling plate with its imaging direction facing downward (toward the negative Z-axis direction). By moving the mounting head 12 above the board 6 held by the board transport unit 5, the board recognition camera 14 images position recognition marks and the like on the board 6, and after component mounting, moves above the board 6 to image the components mounted on the board 6.

[0031] By performing image recognition processing on the image information acquired by the component recognition camera 9 and the board recognition camera 14, it is possible to detect positional misalignment of the component held by the suction nozzle 12a in the mounting head 12, and positional misalignment of the board 6 held by the board transport unit 5. In the component mounting operation, the mounting head 12 takes these positional misalignments into account, corrects the position, and mounts the component at the mounting position on the board 6.

[0032] 3, a dolly 15 having a plurality of tape feeders 8 mounted on a feeder base 15a is set in the component supply unit 7. The position of the dolly 15 is fixed in the component supply unit 7 by clamping the feeder base 15a to a fixed base 15c provided on the base 4 by a clamp mechanism 15b. The dolly 15 holds tape reels 16 that store carrier tapes 17 holding components in a wound state. The carrier tape 17 pulled out from the tape reel 16 is pitch-fed by the tape feeder 8 to a pick-up position 8a by the suction nozzle 12a.

[0033] The component mounting devices M2 to M4 shown in this embodiment employ a tape splicing method in which the tail end of carrier tape 17 (preceding tape) already mounted on tape feeder 8 is spliced ​​to the head end of carrier tape 17 (following tape) to be newly mounted when components run out, at a joint J using adhesive tape. Therefore, carrier tape 17 is continuously supplied to tape feeder 8 without interruption due to replacement of tape reel 16.

[0034] Then, the mounting head 12 accesses the pickup position 8a of the tape feeder 8 and performs a component suction operation, whereby the component is picked up from the pickup position 8a by the suction nozzle 12a. Next, the mounting head 12 that has picked up the component moves above the component recognition camera 9, whereby the component held by the mounting head 12 is imaged by the component recognition camera 9, thereby performing component recognition.

[0035] In the process of carrying out the above-mentioned component mounting operation, the worker performs various tasks, such as a component setup task of mounting tape reel 16 on trolley 15, a splicing task of joining an already mounted preceding tape to a new succeeding tape, a pickup teach task of checking the operating conditions when mounting head 12 picks up and removes components and adjusting them as necessary, and a recognition teach task of checking the recognition conditions of the image capture results by component recognition camera 9 and adjusting them as necessary.

[0036] Next, the configuration of a control system in each of component mounting apparatuses M2 to M4 of component mounting system 1 will be described.

[0037] As shown in Figures 2 and 4, component mounting devices M2 to M4 of component mounting system 1 include a base 4, a board transport unit 5, a component supply unit 7, a Y-axis moving table 10, an X-axis moving table 11, a mounting head 12 that constitutes a component mounting mechanism 13, a component recognition camera 9, and a board recognition camera 14, as well as a first memory unit 22 and a first control unit 21.

[0038] The first storage unit 22 stores a mounting operation program, mounting information, component information, production plan information, progress information, and the like, which are necessary for component mounting work.

[0039] The first control unit 21 is a processing calculation device, and executes various programs stored in the first storage unit 22 to control each unit and cause the component mounting devices M2 to M4 to perform work operations and various processes. Specifically, the first control unit 21 controls the mechanism drive units of the component mounting devices M2 to M4 to drive the board transport unit 5, the component supply unit 7, the component mounting mechanism 13, and the like. The first control unit 21 controls the above-mentioned each unit with reference to the mounting information stored in the first storage unit 22, thereby executing the component mounting work. The first control unit 21 may be included in the control unit.

[0040] Next, the tape feeder 8 will be described.

[0041] As shown in FIG. 5, the tape feeder 8 feeds components by unwinding a tape that contains a plurality of components. The tape feeder 8 is attached with the lower surface of the main body 4a, which is an elongated frame member, aligned with the upper surface of the feeder base 15a, and the position is fixed by engaging the locking portion 4b provided on the lower surface of the main body 4a with the end of the feeder base 15a. In this state, the third control unit 81 that controls the feeder built into the main body 4a is connected to the first control unit 21 of the component mounting device M2 to M4 in FIG. 4 through the connector provided on the locking portion 4b. The third control unit 81 is connected to a sensor 4d for detecting a joint portion, which will be described later.

[0042] A sprocket 4e is disposed at the front end (right side in Fig. 5) of tape feeder 8. As shown in Fig. 6, feed pins 21a are provided at equal pitches on the outer periphery of sprocket 4e, which engage with feed holes 7b for tape feeding provided at a predetermined pitch in carrier tape 17, and a tooth surface is provided on the side of sprocket 4e which engages with a bevel gear connected to the output shaft of tape feed motor 4f.

[0043] Driving the tape feed motor 4f rotates the sprocket 4e, thereby feeding the carrier tape 17. In this tape feeding operation, the sprocket 4e performs intermittent rotation corresponding to a pitch feed pattern, and by controlling the rotation of the tape feed motor 4f, the pitch feed speed and tape positioning of the carrier tape 17 are set. The tape feed motor 4f and the sprocket 4e form a tape feeding mechanism that pitch feeds the carrier tape 17 at a predetermined pitch.

[0044] This tape feeding causes carrier tape 17 to be pulled out from tape reel 16 in Fig. 3. The pulled out carrier tape 17 is guided from its rear end into tape feeder 8 and fed forward along the tape feeding path. The front end of tape feeder 8 is the position where components are picked up by mounting head 12 in Fig. 3, and the fed carrier tape 17 is pitch-fed while covered from above by cover member 23 provided on the top surface.

[0045] During this pitch feed, the component P held in the recess 7a of the carrier tape 17 is picked up by the mounting head 12 through the cutout 23a provided in the cover member 23. The cutout 23a serves as a pick-up position for the mounting head 12 to pick up and remove the component P, and the cover tape 7c attached to cover the recess 7a of the carrier tape 17 is peeled off just before the pick-up position. The component P exposed in the recess 7a by the peeling of the cover tape is picked up by the mounting head 12 in FIG. 3 and mounted on the board 6 in FIG. 3.

[0046] A plurality of openings are provided in front of and behind the cutout portion 23a of the cover member 23. A groove portion 23b for allowing the feed pin 21a to escape is provided at a position corresponding to the sprocket 4e on the front side of the cutout portion 23a, so that the feed pin 21a protruding from the feed hole 7b of the carrier tape 17 to the upper surface side does not interfere with the cover member 23.

[0047] An optical sensor 4d is disposed upstream of the cutout 23a, and an opening 23c is provided directly above the sensor 4d. Light from the sensor 4d passes through the sprocket holes 7b and the opening 23c in the carrier tape 17, thereby detecting the sprocket holes 7b. As described below, when the carrier tape 17 is fed below the cover member 23, the sprocket hole detection makes it possible to detect the joint J shown in FIG. 7 where the carrier tape 17 is spliced.

[0048] Splicing of the carrier tape 17 is performed when the carrier tape 17 housed in the tape reel 16 wears out during component mounting operation, causing a shortage of components.

[0049] Next, splicing will be described with reference to FIG.

[0050] FIG. 7(a) shows carrier tape 17A in an already-mounted state and carrier tape 17B housed in a new tape reel.

[0051] In tape splicing, the tail end of carrier tape 17A and the head end of carrier tape 17B are butted together using a special tool, and splicing adhesive tape 35 is attached to the front and back of carrier tape 17 in a predetermined range across the butt line. This joins two carrier tapes 17A and 17B together, as shown in Fig. 7(b). This splicing has the advantage that the carrier tape 17 is continuously pitch-fed without interruption, eliminating the need to stop the mounting operation when replenishing components.

[0052] In the component mounting device shown in this embodiment, during this splicing, not only the adhesive tape 35 for tape joining but also the adhesive tape 33 for closing the feed hole is applied onto the feed hole 7b located near the butt line. The adhesive tape 33 has a slit 33a in the longitudinal direction, so that when the feed pin 21a of the sprocket 4e fits into the feed hole 7b from below, the feed pin 21a can protrude upward through the slit 33a, and tape feeding is not hindered.

[0053] The sprocket hole blocking is performed for the purpose of distinguishing the joint J, which is formed by splicing the carrier tapes 17A and 17B, from the other parts so that the joint J can be automatically detected by using the sprocket holes 7b. That is, when the normal part of the carrier tape 17 passes above the sensor 4d, as shown in FIG. 8(a), the light from the sensor 4d passes upward through the sprocket holes 7b and the opening 23c at the timing when the sprocket holes 7b are located between the sensor 4d and the opening 23c, and the sprocket holes are detected. Then, this sprocket hole detection signal is repeatedly output at intervals corresponding to the sprocket hole pitch. On the other hand, as shown in FIG. 8(b), when the joint J, in which the sprocket holes 7b are blocked by the adhesive tape 33, passes above the sensor 4d, the sprocket holes 7b are not detected in the area where the adhesive tape 33 is attached. Therefore, by continuously monitoring the sprocket hole detection signal from the sensor 4d, it is detected that the joint J, which is formed by splicing the carrier tapes 17, has passed the position of the sensor 4d.

[0054] Next, the configuration of a control system in tape feeder 8 will be described with reference to FIGS.

[0055] The tape feeder 8 includes a third control unit 81, a tape driving unit 83, a joint detection unit 84, and a third storage unit .

[0056] The third control unit 81 can control the tape driving unit 83 and the like based on a control signal from the first control unit 21. The tape driving unit 83 drives the tape feed motor 4f in FIG.

[0057] The joint detection unit 84 detects, based on a feed hole detection signal from the sensor, that the joint J joined by the splicing operation has passed the position of the sensor 4d in FIG.

[0058] The third storage unit 82 stores the used tape information read by the reading device 3c and transmitted from the management device 3. For example, when a first succeeding tape is spliced ​​to the rear end of a leading tape, the used tape information of the third storage unit 82 includes information on the leading tape and information on the first succeeding tape. In the case of the present embodiment, when a second succeeding tape is spliced ​​to the rear end of a first succeeding tape, the used tape information of the third storage unit 82 includes information on the leading tape and information on the first succeeding tape, but does not include information on the second succeeding tape. In this way, the used tape information of the third storage unit 82 includes two pieces of information: information on the leading tape and information on the succeeding tape spliced ​​to the leading tape (information on the first succeeding tape). Here, the third storage unit 82 is included in the feeder storage unit. The third storage unit 82 may be included in the used tape information. The third control unit 81 is included in the control unit.

[0059] Incidentally, the use tape information of the third storage unit 82 including only two pieces of information, information on the preceding tape and information on the first following tape, is merely an example and is not limited to this. For example, the use tape information of the third storage unit 82 may further include information on a second following tape in addition to information on the preceding tape and information on the first following tape, and when one or more other following tapes are spliced ​​from the second following tape to the tape reel 16 side, information on one or more other following tapes may be included. For this reason, the information included in the use tape information is not limited to two pieces, information on the preceding tape and information on the first following tape following information on the preceding tape.

[0060] Next, the configuration of a control system in the management device 3 will be described.

[0061] The management device 3 includes a second control unit 32, a second storage unit 31, and a communication unit .

[0062] The second control unit 32 is a processing and calculation device, and performs overall management of the component mounting system 1 by controlling the following units based on the programs and information stored in the second storage unit 31. The second control unit 32 is included in the control unit.

[0063] In this embodiment, the second control unit 32 stores the used tape information in the second storage unit 31. The used tape information includes information on the preceding tape currently being used by the component mounting device. The used tape information may also include information on the succeeding tape in addition to the information on the preceding tape.

[0064] Specifically, when the leading end of the first following tape is spliced ​​to the trailing end of the preceding tape, the second control unit 32 stores information about the first following tape in addition to information about the preceding tape in the second storage unit 31. In this case, the used tape information includes information about the preceding tape and information about the first following tape.

[0065] Furthermore, when the leading end of the second following tape is spliced ​​to the trailing end of the first following tape, the second control unit 32 stores information about the second following tape in the second storage unit 31 in addition to information about the preceding tape and information about the first following tape. In this case, the tape usage information includes information about the preceding tape, information about the first following tape, and information about the second following tape.

[0066] In this way, every time a subsequent tape is spliced, the second control unit 32 adds information about the subsequent tape and stores it in the second storage unit 31. Furthermore, when the preceding tape ends, the second control unit 32 deletes the information about the preceding tape from the used tape information, thereby storing updated used tape information in the second storage unit 31. Here, deleting information about the XX tape from the used tape information means making the information about the XX tape empty (NULL value). Note that information about the ended tape may be stored in the second storage unit 31 as the history of the carrier tape 17.

[0067] Furthermore, the second control unit 32 transmits the tape usage information stored in the second storage unit 31 to the tape feeder 8, thereby causing the tape usage information to be stored in the third storage unit 82 of the tape feeder 8. As a result, the tape usage information is also stored in the tape feeder 8, so that the tape feeder 8 side can grasp the switching timing in the tape feeder 8 in real time.

[0068] Here, the information on the leading tape is information indicating the leading tape currently being used, and includes the number of remaining components indicating the number of components held at that time by the leading tape already mounted on the tape feeder 8, the names of components held by the already mounted leading tape, and a reel ID which is an identification code identifying the tape reel 16 holding the already mounted leading tape. The information on the first following tape includes the number of remaining components indicating the number of components held at that time by the first following tape following the leading tape, the names of components held by the first following tape, and a reel ID which is an identification code identifying the tape reel 16 holding the first following tape. The information on the second following tape includes the number of remaining components indicating the number of components held at that time by the second following tape following the first following tape, the names of components held by the second following tape, and a reel ID which is an identification code identifying the tape reel 16 holding the second following tape.

[0069] Used tape information is stored in the second storage unit 31. As described above, when the leading end of the first following tape is spliced ​​to the trailing end of the leading tape, the second storage unit 31 stores information about the first following tape in addition to information about the leading tape as used tape information. Also, when the leading end of the second following tape is spliced ​​to the trailing end of the first following tape, the second storage unit 31 stores information about the second following tape in addition to information about the leading tape and the first following tape as used tape information. The second storage unit 31 is included in the used tape information storage unit.

[0070] The communication unit 38 is a communication interface. The communication unit 38 receives signals between the devices constituting the component mounting system 1 and receives information wirelessly transmitted from the reading device 3c.

[0071] For example, the communication unit 38 can receive information about the leading tape from the reading device 3c when the tape reel 16 is attached to the cart 15. Furthermore, when a first following tape is spliced ​​to the rear end of the leading tape, the communication unit 38 can also receive information about the first following tape from the reading device 3c. Furthermore, when a second following tape is spliced ​​to the rear end of the first following tape, the communication unit 38 can also receive information about the second following tape from the reading device 3c. The information received by the communication unit 38 is stored in the second memory unit 31 by the second control unit 32 as tape usage information.

[0072] Next, the reading device 3c will be described.

[0073] The reading device 3c is a terminal carried by a worker. The reading device 3c is, for example, a barcode reader, a smartphone, a tablet terminal, etc. The reading device 3c is capable of communicating with the management device 3.

[0074] The reading device 3c obtains information about the carrier tape 17 by reading a label provided on the tape reel 16. For example, when an operator performs a splicing operation in which a first following tape is joined to the rear end of a leading tape, the reading device 3c reads and obtains information about the first following tape from the first following tape. The reading device 3c transmits the obtained information about the first following tape to the management device 3. At this time, the reading device 3c may also obtain information about the leading tape, and transmit the information about the leading tape and the information about the first following tape to the management device 3. As a result, the second storage unit 31 of the management device 3 stores information about the first following tape in addition to information about the leading tape.

[0075] In another example, when an operator performs a splicing operation in which a second following tape is spliced ​​to the rear end of a first following tape, the reading device 3c reads and acquires information about the second following tape from the second following tape. The reading device 3c transmits the acquired information about the second following tape to the management device 3. At this time, the reading device 3c may also acquire information about the leading tape and information about the first following tape, and transmit the information about the leading tape, information about the first following tape, and information about the second following tape to the management device 3. As a result, the second storage unit 31 of the management device 3 stores information about the second following tape in addition to information about the leading tape and information about the first following tape.

[0076] <Processing Operation> The processing operations of the component mounting system 1 or the component mounting method according to this embodiment will be described.

[0077] (Example 1) This operation example will be described with reference to Fig. 9. Fig. 9 is a flowchart showing the processing operation of the component mounting system 1 according to the embodiment.

[0078] First, as shown in Fig. 9, the carrier tape 17, i.e., the leading tape, is set on the tape feeder 8 (S11). At this time, the reading device 3c acquires information about the carrier tape 17 from the carrier tape 17 attached to the tape feeder 8 through the operation of an operator. The information about the carrier tape 17 can become information about the leading tape. In the component mounting devices M2 to M4, a dolly 15 with a plurality of tape feeders 8 attached in advance to the feeder base 15a is set in the component supplying section 7. This allows the carrier tape 17 to be pitch-fed by the tape feeders 8.

[0079] Next, in order for the reading device 3c to transmit information about the preceding tape to the management device 3, the second control unit 32 of the management device 3 stores the information about the preceding tape in the second storage unit 31 (S12). For example, when the first following tape is not spliced ​​to the rear end of the preceding tape, the used tape information stored in the second storage unit 31 includes information about the preceding tape and information about the first following tape, which is empty (NULL value). Also, when the first following tape is spliced ​​to the rear end of the preceding tape, the used tape information indicates information about the preceding tape and information about the first following tape spliced ​​to the rear end of the preceding tape.

[0080] Next, the second control unit 32 transmits the information about the leading tape and the information about the first following tape to the tape feeder 8 via the communications network 2 (S13). The third control unit 81 of the tape feeder 8 acquires the information about the leading tape and the information about the first following tape read by the reading device 3c from the management device 3, and causes the third memory unit 82 to store the information about the leading tape and the information about the first following tape.

[0081] Next, the component mounting system 1 starts production (S14).

[0082] Next, the second control unit 32 determines whether or not the splicing operation has been performed (S15). In the splicing operation performed here, the succeeding tape is spliced. For example, when only the leading tape is set in the tape feeder 8, a first succeeding tape may be spliced ​​to the rear end of the leading tape as the succeeding tape, and a second succeeding tape may be spliced ​​to the rear end of the first succeeding tape. In this manner, one or more succeeding tapes are spliced ​​in series. Here, the succeeding tape is a general term including the first succeeding tape, the second succeeding tape spliced ​​to the rear end of the first succeeding tape, the third succeeding tape spliced ​​to the rear end of the second succeeding tape, and the succeeding tape similarly spliced ​​from the third succeeding tape to the tape reel 16 side.

[0083] When the second control unit 32 determines that the splicing operation has been performed (YES in S15), the reading device 3c, by the operation of the worker, reads information of the subsequent tape from the subsequent tape on which the splicing operation has been performed in step S15. In order for the reading device 3c to transmit the information of the subsequent tape to the management device 3, the second control unit 32 stores the information of the subsequent tape in the second storage unit 31 (S16). For example, when the splicing operation has been performed in step S15 and the subsequent tape has been spliced, the second control unit 32 stores information of the spliced ​​subsequent tape in the second storage unit 31.

[0084] Next, the second control unit 32 transmits the information about the leading tape and the information about the first following tape to the tape feeder 8 via the communications network 2 (S17). The third control unit 81 of the tape feeder 8 acquires the information about the leading tape and the first following tape read by the reading device 3c from the management device 3, and stores the information about the leading tape and the first following tape in the third storage unit 82. Then, the component mounting system 1 returns the processing operation to step S15.

[0085] On the other hand, when the second control unit 32 determines that the splicing operation is not being performed (NO in S15), the second control unit 32 determines whether the preceding tape has ended (S18). Note that the second control unit 32 may determine whether the preceding tape has ended based on whether the number of remaining components on the preceding tape is equal to or less than a predetermined value.

[0086] Next, when the second control unit 32 determines that the preceding tape has not ended, for example, that the number of remaining components on the preceding tape is greater than a predetermined value (NO in S18), the second control unit 32 returns the processing operation to step S15. Then, when the second control unit 32 determines YES in step S15, the component mounting system 1 performs the processing operation described above.

[0087] On the other hand, when the second control unit 32 determines that the preceding tape has run out (YES in S18), it updates the used tape information (S19). Note that the second control unit 32 may determine that the preceding tape has run out when the remaining number of components on the preceding tape is equal to or less than a predetermined value.

[0088] When the leading tape ends, the second control unit 32 deletes the information of the ended leading tape from the used tape information, and stores the used tape information updated by moving the information of the first subsequent tape to the information of the leading tape in the second storage unit 31 in association with the transition from the first subsequent tape to the leading tape. Also, if information of a second subsequent tape is present in the used tape information, the second control unit 32 stores the used tape information updated by moving the information of the second subsequent tape to the information of the first subsequent tape in association with the transition from the second subsequent tape to the first subsequent tape in the second storage unit 31. In this way, every time the leading tape ends, the used tape information updated by moving the information of the subsequent tape is stored in the second storage unit 31.

[0089] Next, the second control unit 32 determines whether or not a preceding tape exists after the update based on the updated used tape information (S20).

[0090] When the second control unit 32 determines that the updated preceding tape does not exist (NO in S20), it ends the flow chart of FIG.

[0091] On the other hand, if the second control unit 32 determines that an updated leading tape exists (YES in S20), the second control unit 32 sends information about the leading tape and information about the first subsequent tape to the tape feeder 8 in step S17, and then returns to step S15.

[0092] In this manner, in this processing operation, the above-mentioned processing can be repeated. In this processing operation, even if the tape usage information stored in the third storage unit 82 is limited, it becomes possible to grasp the carrier tape 17 currently being used by the tape feeder 8.

[0093] (Example 2) This operation example will be described with reference to FIG.

[0094] FIG. 10 is a diagram showing the state of carrier tape 17 provided in tape feeder 8, the used tape information in third storage unit 82, and the used tape information in second storage unit 31. As shown in FIG.

[0095] First, as shown in Fig. 10(a), when carrier tape A is provided in tape feeder 8, the used tape information stored in second storage unit 31 includes carrier tape A as information on the preceding tape, and information on the first following tape. When the first following tape is not spliced ​​to the preceding tape, the information on the first following tape in Fig. 10(a) included in the used tape information is empty (NULL value). When the first following tape is spliced ​​to the preceding tape, the information on the first following tape indicates information on the spliced ​​carrier tape.

[0096] Next, the second control unit 32 transmits the information about the leading tape and the information about the first following tape to the tape feeder 8 via the communication network 2. The third control unit 81 of the tape feeder 8 acquires the information about the leading tape and the information about the first following tape read by the reading device 3c from the management device 3, and stores the information about the leading tape and the information about the first following tape in the third storage unit 82. In the case of (a) in Figure 10, the used tape information stored in the third storage unit 82 also includes carrier tape A as the information about the leading tape and null (NULL value) as the information about the first following tape.

[0097] Next, as shown in (b) of Figure 10, when carrier tape B, the first subsequent tape, is spliced ​​to carrier tape A, the preceding tape, by a splicing operation, the used tape information stored in the second memory unit 31 includes carrier tape A as information on the preceding tape and carrier tape B as information on the first subsequent tape.

[0098] Next, the second control unit 32 transmits the leading tape information indicating carrier tape A and the first following tape information indicating carrier tape B to the tape feeder 8 via the communication network 2. The third control unit 81 of the tape feeder 8 acquires the leading tape information and the first following tape information read by the reading device 3c from the management device 3, and stores the leading tape information and the first following tape information in the third memory unit 82. The used tape information stored in the third memory unit 82 also includes carrier tape A as the leading tape information and carrier tape B as the first following tape information.

[0099] Next, as shown in (c) of Figure 10, when the second subsequent tape, carrier tape C, is spliced ​​to the first subsequent tape, carrier tape B, by a splicing operation, the used tape information stored in the second memory unit 31 includes carrier tape A as information on the preceding tape, carrier tape B as information on the first subsequent tape, and carrier tape C as information on the second subsequent tape.

[0100] Next, the second control unit 32 transmits the information on the leading tape indicating carrier tape A and the information on the first following tape indicating carrier tape B to the tape feeder 8 via the communication network 2. The third control unit 81 of the tape feeder 8 acquires the information on the leading tape and the information on the first following tape, which are information on the two tapes on the tape feeder 8 side, from the management device 3, even if a second following tape is spliced ​​to the rear end of the first following tape. Then, the third control unit 81 stores the information on the leading tape and the information on the first following tape in the third storage unit 82. The used tape information stored in the third storage unit 82 also includes carrier tape A as the information on the leading tape and carrier tape B as the information on the first following tape.

[0101] 10(d), when the carrier tape A, which is the leading tape, ends, the second control unit 32 rewrites the used tape information from carrier tape A as the information of the leading tape, carrier tape B as the information of the first subsequent tape, and carrier tape C as the information of the second subsequent tape to carrier tape B as the information of the leading tape and carrier tape C as the information of the first subsequent tape. In other words, the second control unit 32 updates the used tape information of the second storage unit 31 so as to delete carrier tape A as the information of the leading tape, to move carrier tape B from the information of the first subsequent tape to the information of the leading tape, and to move carrier tape C from the information of the second subsequent tape to the information of the first subsequent tape.

[0102] Next, as shown in (d) of FIG. 10, the second control unit 32 transmits the leading tape information indicating carrier tape B and the first following tape information indicating carrier tape C to the tape feeder 8 via the communication network 2. The third control unit 81 acquires the leading tape information and the first following tape information from the management device 3. Then, the third control unit 81 stores the leading tape information and the first following tape information in the third memory unit 82. The used tape information stored in the third memory unit 82 also includes carrier tape B as the leading tape information and carrier tape C as the first following tape information.

[0103] As in this operation example, the third storage unit 82 may have a small storage capacity and may be able to store only two pieces of tape information. In this case, the used tape information stored in the third storage unit 82 may only include, for example, carrier tape A as the information of the preceding tape and carrier tape B as the information of the first succeeding tape, as shown in FIG. 10(c). Even in this case, as shown in FIG. 10(d), when the preceding tape, carrier tape A, is finished, the third control unit 81 acquires used tape information from the management device 3 and rewrites (moves up) the used tape information stored in the third storage unit 82 from carrier tape A as the information of the preceding tape and carrier tape B as the information of the first succeeding tape to carrier tape B as the information of the preceding tape and carrier tape C as the information of the first succeeding tape. Therefore, even if the used tape information stored in the third storage unit 82 is limited, the carrier tape 17 currently being used by the tape feeder 8 can be grasped.

[0104] <Action and effect> Next, the effects of the component mounting system 1 and the component mounting method according to this embodiment will be described.

[0105] As described above, component mounting system 1 according to the present embodiment includes tape feeder 8 that supplies components by feeding out a tape containing a plurality of components, and a component mounting device that takes out the components supplied by tape feeder 8 and mounts them on a board. Component mounting system 1 includes a used tape information storage unit (second storage unit 31) that stores information on a leading tape currently being used by the component mounting device, and a control unit (second control unit 32) that stores information on the first following tape in addition to the information on the leading tape in the used tape information storage unit when the leading end of the leading tape is spliced ​​with the leading end of the first following tape, and stores information on the second following tape in addition to the information on the leading tape and the first following tape in the used tape information storage unit when the leading end of the second following tape is spliced ​​with the leading end of the first following tape.

[0106] For example, by splicing a first succeeding tape to a preceding tape, information on the first succeeding tape can be stored in addition to information on the preceding tape. Also, information can be stored in the second succeeding tape. Therefore, the carrier tape 17 currently being used by the component mounting device can be known.

[0107] Therefore, according to the component mounting system 1, even if three or more carrier tapes 17 are spliced ​​together, it is possible to adequately manage the carrier tapes 17.

[0108] Furthermore, the component mounting method according to this embodiment is a component mounting method that uses a tape feeder 8 that supplies components by unwinding a tape that contains a plurality of components, and component mounting devices M2 to M4 that take out the components supplied by the tape feeder 8 and mount them on a board, and includes the steps of: a used tape information storage unit storing information of a leading tape currently being used by component mounting devices M2 to M4; and, when the leading end of the leading tape is joined to the leading end of a first following tape, a control unit storing information of the first following tape in addition to the information of the leading tape in the used tape information storage unit; and, when the leading end of a second following tape is joined to the leading end of the first following tape, a control unit storing information of the second following tape in addition to the information of the leading tape and the information of the first following tape in the used tape information storage unit.

[0109] This component mounting method also provides the same effects as those described above.

[0110] In the component mounting system 1 according to the present embodiment, the tape use information storage unit is provided in the tape feeder 8.

[0111] According to this, since the tape feeder 8 also stores the tape usage information, the tape feeder 8 can grasp the timing of switching the carrier tape 17 in real time. Therefore, the tape feeder 8 can also manage the carrier tape 17.

[0112] In the component mounting system 1 according to the present embodiment, the tape use information storage unit is provided outside the tape feeder 8 and the component mounting devices M2 to M4 (in the management device 3).

[0113] According to this, the management device 3 can also manage the carrier tape 17.

[0114] Moreover, in component mounting system 1 according to the present embodiment, tape feeder 8 has a feeder storage unit (third storage unit 82) that stores information about the preceding tape and information about the first succeeding tape.

[0115] According to this, the carrier tape 17 can be managed by the tape feeder 8 as well.

[0116] In addition, in the component mounting system 1 of this embodiment, when the preceding tape is finished, the control unit stores the updated used tape information in the used tape information storage unit by deleting information about the preceding tape from the used tape information that includes information about the preceding tape.

[0117] According to this, the second control unit 32 can grasp that the preceding tape has run out, and can notify the worker to prompt the worker to splice a new carrier tape 17. In addition, by deleting information about the preceding tape that has run out from the used tape information, an increase in the used tape information can be suppressed.

[0118] (Other variations) Although the component mounting system and the component mounting method according to the present disclosure have been described based on the above-mentioned embodiments, the present disclosure is not limited to these embodiments.
