[0030] Hereinafter, exemplary embodiments of a component mounting device according to the present disclosure will be described with reference to the accompanying drawings. The present disclosure is not limited to the specific configurations of the following embodiments, and configurations based on similar technical ideas are also included in the present disclosure.

[0031] (Embodiment) First, a component mounting device 1 according to an embodiment of the present disclosure will be described with reference to Figures 1 and 2. Figure 1 is a side view of a main part of the component mounting device equipped with a tape cassette. Figure 2 is a side view of a component supply unit of the component mounting device.

[0032] The component mounting device 1 is a device that repeatedly performs a series of component mounting operations, mounting components 5 onto a substrate 4 carried in from another device in an upstream process and carrying the substrate out to another device in a downstream process. The component mounting device 1 includes a main body 2 and a component supply unit 3.

[0033] In FIG. 1, the main body 2 includes a base 11, a board transport unit 12, a mounting head 13, and a head moving mechanism 14. Although not shown in FIG. 1, the main body 2 also includes a monitor 15, an operation unit 16, and a main body control unit 17 (see FIG. 22). The board transport unit 12 includes a conveyor mechanism, which transports the board 4 received from an upstream process device horizontally and positions it at a predetermined working position. In this embodiment, the transport direction of the board 4 in the component mounting device 1 is defined as the X direction (horizontal direction), and the up-down direction is defined as the Z direction. Furthermore, the direction perpendicular to both the X direction and the Z direction is defined as the Y direction (front-to-back direction).

[0034] 1, the mounting head 13 has a plurality of nozzles 13a extending downward, and the lower end of each nozzle 13a generates a vacuum suction force that attracts the component 5. The head movement mechanism 14 has, for example, an XY table, and moves the mounting head 13 within the XY plane.

[0035] 1 and 2, the component supply section 3 includes a cart 21, a tape cassette 22, and a component supply unit 23. The tape cassette 22 is configured to store a roll 25 in which a carrier tape 24 is wound into a disk shape without a core (see FIG. 6). In this way, the tape cassette 22 handles the roll 25 that is not wound on a reel.

[0036] A wireless tag 28 is attached to the tape cassette 22 and records component information about the stored roll 25. Every time the stored roll 25 is changed, the component information recorded on the wireless tag 28 is rewritten.

[0037] 1, the base 11 includes a pair of carriage holders 11a extending rearward and arranged opposite each other in the X direction. The pair of carriage holders 11a are members that secure the carriage 21 to the base 11 by sandwiching and holding the carriage 21 close to the base 11 from the left and right.

[0038] 3 and 4, a supply unit base 31 is provided on the top of the carriage 21. An attachment slot 31a extending in the Y direction is provided on the top surface of the supply unit base 31 for attaching the component supply unit 23. The component supply unit 23 supplies components 5 to the mounting head 13 of the component mounting device 1, and is, for example, a tape feeder. The component supply unit 23 can be attached to the supply unit base 31 by sliding a slide protrusion 23e (FIG. 5) provided on the underside of the component supply unit 23 into the attachment slot 31a of the supply unit base 31. The supply unit base 31 is provided with a plurality of attachment slots 31a aligned in the X direction. This allows a plurality of component supply units 23 to be attached to the supply unit base 31 aligned in the X direction.

[0039] A plurality of unit base-side connectors 30 are attached to the rear surface of the supply unit base 31. One unit base-side connector 30 is disposed at a position overlapping an extension line of one mounting slot 31a. The component supply unit 23 has a unit-side connector 65 (see FIG. 8), and when mounted in the mounting slot 31a, the unit-side connector 65 and the unit base-side connector 30 are connected. In this manner, the supply unit base 31 is configured to have a plurality of supply unit mounting sections 31b (shown by dashed lines in FIGS. 3 and 4) for mounting the component supply units 23. In this embodiment, one supply unit mounting section 31b includes one mounting slot 31a and a unit base-side connector 30. In this manner, the cart 21 of this embodiment includes a supply unit base 31 provided with a plurality of mounting slots 31a for mounting the component supply units 23 and supply unit mounting sections 31b each having a connector (unit base-side connector 30) electrically connected to the component supply unit 23.

[0040] As shown in Figures 1 and 2, the cart 21 has a cart base 32 that is movable on the floor 20. As shown in Figure 5, the cart base 32 has a support column 32a at its front (right side) that supports the supply unit base 31 from below, and a cassette mounting base 33 that is formed in a generally flat plate shape at its rear (left side). The cart 21 is configured to be able to hold a plurality of tape cassettes 22 in the space between the supply unit base 31 and the cassette mounting base 33. A pair of lower brackets 34 that extend upward are provided at the middle of the cart base 32 in the front-to-rear direction, facing each other in the X direction. Both ends of a lower support bar 35 that extends in the X direction are supported by the pair of lower brackets 34.

[0041] 4 and 5, a plurality of pairs of upper brackets 36 extending downward are provided side by side at intervals in the X direction below the supply unit base 31. An upper support bar 37 extending in the X direction so as to penetrate through the upper brackets 36 is supported by the upper brackets 36. The upper support bar 37 extends above the lower support bar 35 and parallel to the lower support bar 35.

[0042] The dolly 21 is configured to be able to hold a plurality of tape cassettes 22 in the space sandwiched between the supply unit base 31 and the cassette mounting table 33. The dolly 21 has a cassette base 46 constituted by the cassette mounting table 33, a lower support bar 35, and an upper support bar 37, and a plurality of tape cassettes 22 are held on this cassette base 46. The cassette base 46 has a plurality of cassette mounting portions 46a. A plurality of cassette mounting portions 46a are provided along the X direction and are divided in the X direction by the upper bracket 36.

[0043] In this way, the cart 21 is equipped with a supply unit base 31 having a plurality of supply unit mounting portions 31b each having a mounting slot 31a for mounting the component supply unit 23 and a unit base side connector 30 electrically connected to the component supply unit 23, and a cassette base 46 having a plurality of cassette mounting portions 46a arranged along the X direction.

[0044] Each component supply unit 23 mounted on the supply unit base 31 is a so-called autoload feeder that transports a carrier tape 24 inserted into a tape inlet 23a (FIG. 1) provided at the rear end of the component supply unit 23 forward and supplies components 5 held on the carrier tape to a component supply outlet 23b at a predetermined position. As shown in FIG. 1, the tape inlet 23a can hold a carrier tape 24 (next tape 24b) to be used after the current tape 24a, in addition to the carrier tape 24 (current tape 24a) currently being transported by the component supply unit 23. When the components on the current tape 24a run out, the current tape 24a is ejected and the next tape 24b is automatically transported, and the components 5 held on the next tape 24b are supplied to the component supply outlet 23b.

[0045] In this embodiment, the tape cassette 22 is used in two ways. In the first way, it is used as a receiver for the roll 25 of the current tape 24a, and is mounted across the carriage base 32 and the cassette mounting table 33. Such a tape cassette 22 used as a receiver for the roll 25 of the current tape 24a will be referred to as a "receiving cassette 22A" below (FIGS. 1 and 2).

[0046] In a second usage mode, the tape cassette 22 is used as a storage device for storing a roll 25 of the next tape 24b, which is a replacement carrier tape 24 used after the current tape 24a runs out, and is attached to the cassette mounting base 33. A tape cassette 22 used as a storage device for a roll 25 of the next tape 24b will be referred to as a "storage cassette 22B" hereinafter (FIGS. 1 and 2). As such, the receiving cassette 22A and the storage cassette 22B are tape cassettes 22 having the same structure. Note that in this embodiment, the receiving cassette 22A and the storage cassette 22B have the same structure, and when the tape cassette 22 is used as the receiving cassette 22A, it is attached upside down in the cassette attachment portion 46a.

[0047] The leading end of the carrier tape 24 (next tape 24b) pulled out from the roll 25 in the storage cassette 22B can be inserted into the tape inlet 23a of the component supply unit 23 even before the current tape 24a runs out of components. When the component supply unit 23 detects that the end of the current tape 24a has passed a predetermined position in the component supply unit 23, it starts transporting the next tape 24b. This allows components 5 to be continuously supplied to the component mounting device 1. The component supply unit 23 pulls out the carrier tape 24 from the roll 25 in the receiving cassette 22A and supplies the components 5 to the mounting head 13, and then pulls out another carrier tape 24 from the roll 25 in the storage cassette 22B and supplies the components 5 to the mounting head 13.

[0048] When component mounting device 1 performs a component mounting operation, first, board transport unit 12 operates to carry in board 4 from outside and position it at a predetermined work position. Once board 4 has been positioned at the work position by board transport unit 12, component supply unit 23 repeatedly performs a mounting turn by supplying components 5 to component supply port 23b and moving mounting head 13 using head moving mechanism 14.

[0049] In one mounting turn, the mounting head 13 performs a series of operations: it moves to a position above the component supply unit 23 and picks up the component 5 with the nozzle 13a, then moves to a position above the board 4 and mounts the component 5 on the board 4. Once all the components 5 to be mounted on the board 4 have been mounted by repeatedly performing the mounting turn, the board transport unit 12 operates and transports the board 4 to a downstream process device. This completes the component mounting operation for one board 4.

[0050] Next, the configuration of the tape cassette 22 used as the receiving cassette 22A or the storage cassette 22B for the roll body 25 of the carrier tape 24 and the procedure for mounting it on the carriage 21 will be described.

[0051] In FIG. 6, the tape cassette 22 has a storage section 41, a shutter 42 serving as a restricting section provided within the storage section 41, and a wireless tag 28. The storage section 41 includes a U-shaped frame 43 (see also FIG. 18) and a pair of plate members (side plates 44) attached to both sides of the frame 43 in the width direction. The space enclosed by the U-shaped frame 43 and the pair of side plates 44 is a storage space for storing the roll 25. The opening of the U-shaped frame 43 faces forward, so that an opening 41b is formed in front of the storage section 41. The roll 25 is stored in the storage section 41 of the tape cassette 22 in a vertical position. Here, "vertical position" refers to a position in which the central axis CJ of the disk-shaped roll 25 is substantially horizontal. The wireless tag 28 is built into the bottom of the frame 43. Component information, etc., described below, is read and written to the wireless tag 28 by a wireless communication unit 29.

[0052] Thus, in this embodiment, the storage section 41 has a U-shaped frame 43 that surrounds the space 41a and a pair of side plates 44 (plate members) fixed to the frame 43 that cover the sides of the space 41a, and the storage section 41 is configured to have an opening 41b in the front that faces the outer peripheral surface of the roll body 25.

[0053] 5, three storage cassette holding pins 33a are arranged in a row in the Y direction on the upper surface of the cassette placing table 33. These three storage cassette holding pins 33a constitute one cassette holding pin row 33b (see FIG. 3), and a plurality of cassette holding pin rows 33b are arranged in a row in the X direction on the upper surface of the cassette placing table 33.

[0054] In front of each cassette holding pin row 33b, one receiving cassette holding pin 33c is provided coaxially with that cassette holding pin row 33b. That is, on the upper surface of the cassette placing table 33, multiple pin rows are provided lined up in the X direction, each pin row including three storage cassette holding pins 33a (cassette holding pin row 33b) and one receiving cassette holding pin 33c.

[0055] As shown in FIG. 5, the receiving cassette 22A is mounted on the carriage 21 with the top and bottom of the storage cassette 22B reversed, i.e., upside down. In this embodiment, one receiving cassette holding pin 33c, the lower support bar 35, and the upper support bar 37 form a receiving cassette mounting section 38 in which the receiving cassette 22A is mounted. In this manner, the receiving cassette mounting section 38 mounts the tape cassette 22 in an upside-down position as the receiving cassette 22A in the component mounting device 1. As shown in FIGS. 2 and 5, a reader / writer 29a is mounted on the upper bracket 36 as the wireless communication unit 29 capable of wireless communication with the wireless tag 28 of the receiving cassette 22A mounted in the receiving cassette mounting section 38. One reader / writer 29a is provided for each receiving cassette mounting section 38.

[0056] As shown in FIGS. 5 and 6, the storage cassette 22B is mounted on the cassette mounting base 33 by inserting three storage cassette holding pins 33a constituting one cassette holding pin row 33b into three pin insertion portions 43b provided in the lower portion of the frame 43. In this embodiment, the portion of the cassette mounting base 33 where the cassette holding pin row 33b (the three storage cassette holding pins 33a aligned in a row in the Y direction) is provided constitutes a storage cassette mounting portion 39 in which the storage cassette 22B is mounted. The cassette mounting portion 46a includes the receiving cassette mounting portion 38 and the storage cassette mounting portion 39. As shown in FIGS. 2 and 5, the cassette mounting base 33 is equipped with a reader / writer 29b as a wireless communication unit 29 capable of wirelessly communicating with the wireless tag 28 of the storage cassette 22B mounted in the storage cassette mounting portion 39. One reader / writer 29b is provided for each storage cassette mounting portion 39.

[0057] 5, the receiving cassette mounting section 38 mounts the receiving cassette 22A with the opening 41b of the receiving cassette 22A facing the storage cassette mounting section 39. The storage cassette mounting section 39 mounts the storage cassette 22B with the opening 41b of the storage cassette 22B facing the receiving cassette 22A mounted in the receiving cassette mounting section 38. In this way, the receiving cassettes 22A and 22B are mounted on the carriage 21 with the opening 41b of the receiving cassette 22A facing the opening 41b of the storage cassette 22B, making it possible to move the roll 25 stored in the storage cassette 22B to the receiving cassette 22A.

[0058] Furthermore, the receiving cassette mounting section 38 mounts the receiving cassette 22A at a lower position than the storage cassette 22B mounted in the storage cassette mounting section 39. This allows the roll 25 to move smoothly from the storage cassette 22B to the receiving cassette 22A, and prevents the roll 25 stored in the receiving cassette 22A from moving to the storage cassette 22B.

[0059] Furthermore, the receiving cassette mounting section 38 mounts the receiving cassette 22A in an inclined position that becomes lower the further it is from the storage cassette mounting section 39. This allows the roll 25 to move smoothly from the storage cassette 22B to the receiving cassette 22A, and prevents the roll 25 stored in the receiving cassette 22A from moving to the storage cassette 22B.

[0060] In this way, the cassette mounting section 46a mounts the receiving cassette 22A and the storage cassette 22B with their respective openings 41b facing each other, in series along the conveying direction (Y direction) of the carrier tape 24 by the component supply unit 23, and with the storage cassette 22B positioned upstream in the conveying direction.

[0061] Next, the carrier tape 24 will be described with reference to Figure 7. Figure 7 is an enlarged view of region AR in Figure 6. The carrier tape 24 has a base tape 51 and a top tape 52. The base tape 51 has a number of pockets 53 that open upward and are arranged in a row at equal intervals along the length of the base tape 51, and a component 5 is stored in each pocket 53. The top tape 52 is attached to the top surface of the base tape 51 and seals the component 5 in the pocket 53. In this way, the carrier tape 24 packages the components 5. A plurality of feed holes 54 are arranged in a row at equal intervals in a position parallel to the row of pockets 53 in the base tape 51.

[0062] The top tape 52 of the carrier tape 24 has an extending portion 52a extending from the leading end 51a of the base tape 51. The extending portion 52a is provided to allow the top tape 52 to be captured by an exposed portion 66, which will be described later, and the dimension of the extending portion 52a from the leading end 51a of the base tape 51 is the length necessary to reach and be captured by the exposed portion 66 from the tape transport path 60. The leading end of the carrier tape 24 is cut so as to divide the feed holes 54.

[0063] <<Parts supply unit>> Next, the configuration of the component supply unit 23 will be described with reference to Fig. 8. Fig. 8 is a schematic diagram of the component supply unit 23 of this embodiment.

[0064] The component supply unit 23 includes a tape transport path 60, a tape transport section 61, a tape loading section 62, a shutter unit 63, a unit control section 64, and a unit-side connector 65. The component supply unit 23 also includes a tape inlet 23a for feeding the carrier tape 24 into the tape transport path 60, a component supply outlet 23b for supplying components, and an outlet 23c for discharging the carrier tape 24 from the tape transport path 60. An alarm lamp 23f and an operation switch 23g are arranged on the top surface of the component supply unit 23 (see FIG. 3).

[0065] The tape transport path 60 is formed in the main body 23d of the component supply unit 23, and guides the carrier tape 24, which is pulled out from the roll body 25 stored in the receiving cassette 22A and inserted into the component supply unit 23 from the tape inlet 23a, through the inside of the component supply unit 23 to the component removal position 23ba, which is the position of the component supply port 23b, and then to the discharge port 23c.

[0066] The tape inlet 23a opens on the upstream side of the component supply unit 23 in the tape feed direction (the left side in FIG. 8). The outlet 23c opens on the downstream side of the tape feed direction (the right side in FIG. 8). The tape transport path 60 communicates from the tape inlet 23a to the outlet 23c. The mounting head 13 removes the component 5 at a component removal position 23ba provided downstream of the tape transport path 60.

[0067] In the process of continuously performing component mounting work, a plurality of carrier tapes 24, each constituting one roll 25, are inserted sequentially from tape inlet 23a and supplied to component supply unit 23. In the following description, as necessary, of two carrier tapes 24 introduced from tape inlet 23a and fed along tape transport path 60, the carrier tape 24 fed first will be referred to as current tape 24a, and the carrier tape 24 fed next to current tape 24a will be referred to as next tape 24b.

[0068] The tape transport unit 61 transports the carrier tape 24 to the component pick-up position 23ba on the downstream side of the tape transport path 60. The tape transport unit 61 includes a first transport sprocket 61a that engages with the carrier tape 24, a second transport sprocket 61b, a third transport sprocket 61c, and a drive unit 61d.

[0069] A first transport sprocket 61a, a second transport sprocket 61b, and a third transport sprocket 61c are arranged along the tape transport path 60 in this order from the downstream side.

[0070] The driving unit 61d includes, for example, a motor as a power source, and a power transmission member that transmits the power of the power source to the first to third conveying sprockets 61a to 61c. The power transmission member is, for example, a gear.

[0071] The tape loading section 62 sends the carrier tape 24 inserted into the component supply unit 23 from the tape inlet 23a to the tape transport section 61. The tape loading section 62 is disposed on the upstream side of the tape transport path 60. The tape loading section 62 includes a loading sprocket 62a, a tape support section 62b, and a drive section 62c.

[0072] The drive unit 62c has the function of rotating the loading sprocket 62a in the direction of arrow a1 and the function of moving the loading sprocket 62a and the tape support unit 62b in the direction of arrow a2. By driving the loading sprocket 62a to rotate in the direction of arrow a1, the loaded carrier tape 24 can be carried downstream.

[0073] The tape transport path 60 widens significantly near the tape inlet 23a on the upstream side of the tape transport path 60, and a tape support part 62b is disposed in this widened space so as to divide the tape transport path 60 in half. Therefore, with the leading end of the next tape 24b supported by the tape support part 62b at the upstream end of the tape transport path 60, the current tape 24a can be transported downstream along the bottom surface 60a of the tape transport path 60 below the tape support part 62b. Furthermore, by moving the input sprocket 62a and the tape support part 62b with the drive part 62c, the next tape 24b supported by the tape support part 62b can be moved to the bottom surface 60a of the tape transport path 60.

[0074] The drive unit 62c includes, for example, a motor as a power source and a power transmission member that transmits the power of the power source to the feed sprocket 62a. The power transmission member is, for example, a gear. The drive unit 62c may also include a power transmission mechanism that combines a link mechanism, gears, elastic members, etc., that uses the power of a separate power source to move the feed sprocket 62a and the tape support unit 62b in the direction of arrow a2.

[0075] The component supply unit 23 includes a first sensor PH1, a second sensor PH2, and a third sensor PH3, which are arranged along the tape transport path 60 in this order from the upstream side.

[0076] The first sensor PH1 detects that the carrier tape 24 inserted into the tape support portion 62b of the component supply unit 23 has reached a first checkpoint provided at the downstream end of the tape support portion 62b.

[0077] The second sensor PH2 detects the presence or absence of the carrier tape 24 at a second check point provided downstream of the first check point and near the junction where the tape support portion 62b joins the tape transport path 60 on the extension of the tape support portion 62b.

[0078] The third sensor PH3 detects the presence or absence of the carrier tape 24 at a third checkpoint located downstream of the exposed portion 66 of the tape transport path 60 and upstream of the component removal position 23ba. The first sensor PH1 to the third sensor PH3 are optical sensors, such as color sensors or photo sensors, that directly or indirectly detect the presence or absence of the carrier tape 24 at each checkpoint.

[0079] When the end of the current tape 24a passes the third checkpoint and the third sensor PH3 no longer detects the carrier tape 24, the input sprocket 62a rotates and the next tape 24b supported by the tape support portion 62b is transported downstream.

[0080] When the leading edge of the next tape 24b passes the third checkpoint and the third sensor PH3 detects the next tape 24b, the drive unit 62c moves the tape support unit 62b to move the next tape 24b into the tape transport path 60 at the tape entrance 23a.

[0081] The tape support portion 62b supports the next tape 24b and maintains the orientation of the next tape 24b as it is fed. See FIG. 9. The tape support portion 62b is composed of a first support portion 62ba and a second support portion 62bb. A thin plate-shaped left cover 62bcL and a thin plate-shaped right cover 62bcR are attached to both sides of the component supply unit 23, sandwiching the tape feed path 60 from the left and right. The upper end of the right cover 62bcR ends at a position lower than the tape support portion 62b, and a thin plate-shaped movable member 62bd is disposed above it to complement the right cover 62bcR. For convenience, in the following description, one side will be referred to as the left and the other as the right, facing the downstream direction in which the carrier tape 24 is fed in the component supply unit 23, as shown in FIG. 8.

[0082] The left cover 62bcL extends in the tape feed direction and the up-down direction (Z direction). The inner surface (right surface) of the left cover 62bcL is a guide surface that guides the left surface of the next tape 24b. The left cover 62bcL is fixed to the left surface of the main body 23d of the component supply unit 23. Similarly, the right cover 62bcR is fixed to the right surface of the main body 23d of the component supply unit 23.

[0083] The first support portion 62ba supports one side in the width direction of the carrier tape 24 from below. The first support portion 62ba is formed on the right side surface of the left cover 62bcL and extends from the tape inlet 23a to below the shutter unit 63. The second support portion 62bb supports the other side of the next tape 24b from below. The second support portion 62bb is formed on the left side surface of a movable member 62bd (described later) and extends downstream from the tape inlet 23a, terminating just before the shutter unit 63.

[0084] The movable member 62bd has a plate-like shape and is attached to the main body 23d of the component supply unit 23 so as to be movable in the vertical direction. The movable member 62bd is attached integrally with the loading sprocket 62a, and when the movable member 62bd moves in the vertical direction, the loading sprocket 62a also moves in the vertical direction. The inner surface of the movable member 62bd is a guide surface that guides the right side surface of the next tape 24b. The movable member 62bd is moved in the vertical direction (arrow a2 in Figure 8) by the drive unit 62c.

[0085] Next, we will explain the function of releasing the next tape 24b from the tape support part 62b into the tape transport path 60. As shown in FIG. 9(a), the next tape 24b is held by the tape support part 62b with the movable member 62bd in its initial position and the second support part 62bb at the same height as the first support part 62ba. When releasing the next tape 24b from the tape support part 62b, the unit control part 64 drives the drive part 62c to move the movable member 62bd upward. This causes the movable member 62bd to rise together with the second support part 62bb and the input sprocket 62a.

[0086] As the movable member 62bd rises, the carrier tape 24 moves upward while being supported on the lower surface of the right side by the second support portion 62bb, and the pin 62aa of the loading sprocket 62a disengages from the feed hole 54 of the carrier tape 24 and twists counterclockwise.

[0087] As shown in FIG. 9(b), when the movable member 62bd rises further, the twist of the carrier tape 24 increases, and eventually the carrier tape 24 slips off the first support portion 62ba and the second support portion 62bb.

[0088] The next tape 24b released from the tape support portion 62b moves to the bottom surface 60a of the tape transport path 60 below the tape support portion 62b. Once the carrier tape 24 (next tape 24b) is released from the tape support portion 62b, the next carrier tape 24 (next tape 24b) can be inserted into the tape support portion 62b at any time.

[0089] <Shutter unit> Next, the shutter unit 63 will be described with reference to Fig. 10. Fig. 10 is a side view showing the configuration of the shutter unit, with Fig. 10(a) showing a state in which the carrier tape 24 has not yet reached the shutter unit 63, and Fig. 10(b) showing a state in which the carrier tape 24 is stopped by the shutter unit 63.

[0090] The shutter unit 63 prevents the carrier tape 24 supported by the tape support portion 62b from proceeding further downstream in the tape transport path 60. The shutter unit 63 includes a tape detection mechanism 63a and a gate unit 63b.

[0091] The tape detection mechanism 63a detects that the carrier tape 24 supported by the tape support portion 62b has reached the shutter unit 63. The tape detection mechanism 63a includes a tape detection piece 71, a pin 72, and a first sensor PH1.

[0092] The tape detection piece 71 has a generally L-shape and includes a plate-like portion 71a extending opposite the tape support portion 62b, a contact portion 71b extending from the upstream side of the plate-like portion 71a toward the tape support portion 62b, and a light-shielding portion 71c extending from the downstream end of the plate-like portion 71a in the opposite direction (upward) from the direction of the tape support portion 62b. The tape detection piece 71 is attached to the main body 23d of the component supply unit 23 so as to be swingable about a fulcrum 71d provided near the upstream end. The plate-like portion 71a is supported from below by a pin 72 fixed downstream of the fulcrum 71d. The contact portion 71b protrudes from the plate-like portion 71a of the tape detection piece 71 toward the first support portion 62ba, and its lower end is positioned so as to be able to contact the leading edge of the carrier tape 24 moving along the upper surface of the first support portion 62ba. The position of the contact portion 71b serves as a first checkpoint for detecting the carrier tape 24.

[0093] The first sensor PH1 is disposed above the light-shielding portion 71c. As shown in FIG. 10(b), when the carrier tape 24 travels downstream along the tape support portion 62b, the leading end of the carrier tape 24 pushes the contact portion 71b downstream, causing the tape detection piece 71 to rotate counterclockwise around the fulcrum 71d. This causes the light-shielding portion 71c to block the light emitted from the first sensor PH1, causing the first sensor PH1 to transmit a detection signal to the unit control portion 64. This makes it possible to detect that the carrier tape 24 has reached the shutter unit 63 (reached the first checkpoint).

[0094] 10(a), the gate unit 63b includes a gate 74, a compression spring 75, a locking member 76, a lever 77, an actuator 78, and a return spring 79. The gate unit 63b controls, based on an instruction from the unit control unit 64, whether the carrier tape 24 supported by the tape support unit 62b is advanced further downstream along the tape transport path 60 or is stopped.

[0095] The gate 74 is, for example, a plate-shaped member, and one end of a compression spring 75 is connected to the upper end of the gate 74. The other end of the compression spring 75 is attached to the main body 23d of the component supply unit 23. The gate 74 is biased toward the first support portion 62ba by the compression spring 75. Therefore, the lower end of the gate 74 is in contact with the upper surface of the first support portion 62ba.

[0096] The gate 74 is prevented from rising against the spring force of the compression spring 75 by a locking member 76. The locking member 76 is, for example, a rod extending laterally, one end of which is inserted laterally into a recess 74a formed in the side surface of the gate 74.

[0097] Lever 77 is attached to main body 23d of component supply unit 23 in a state in which it can swing around fulcrum 77a located in the center. A locking member 76 is fixed to one end (lower end) of lever 77. The other end (upper end) of lever 77 is connected to rod 78a of actuator 78. One end of return spring 79 is connected between fulcrum 77a of lever 77 and one end of lever 77.

[0098] Actuator 78 extends and retracts rod 78a in response to instructions from unit control unit 64. Return spring 79 biases lever 77 in a direction that pulls it, i.e., biases it to rotate clockwise. As a result, return spring 79 causes the tip of locking member 76 to be inserted into recess 74a on the side of gate 74. When locking member 76 is inserted into recess 74a on the side of gate 74, upward movement of gate 74 is restricted, and the gate is in a locked state. On the other hand, when actuator 78 is operated to swing lever 77 counterclockwise against the spring force of return spring 79, locking member 76 is released from recess 74a, allowing upward movement of gate 74, i.e., the gate is unlocked.

[0099] Next, the operation of the shutter unit will be described with reference to Figures 10 to 12. Figure 11 is a side view showing the configuration of the shutter unit, with Figure 11(a) showing a state in which the locking member is unlocked and Figure 11(b) showing a state in which the carrier tape 24 passes through the shutter unit 63. Figure 12 shows a state in which the carrier tape 24 has fallen from the tape support portion 62b.

[0100] As shown in Fig. 10(a), the carrier tape 24 is inserted from the tape inlet 23a along the tape support portion 62b and advances downstream. Next, as shown in Fig. 10(b), when the leading edge of the carrier tape 24 contacts the contact portion 71b of the tape detection piece 71, the contact portion 71b is pushed downstream, causing the tape detection piece 71 to swing counterclockwise around the fulcrum 71d as its central axis. As a result, the light-shielding portion 71c of the tape detection piece 71 blocks the optical path of the first sensor PH1, and the first sensor PH1 sends a detection signal to the unit control portion 64.

[0101] After contact portion 71b of tape detection piece 71 swings, the leading edge of carrier tape 24 comes into contact with gate 74 and pushes gate 74 upward. Gate 74 is pushed upward by carrier tape 24, but the wall surface of recess 74a of gate 74 hits locking member 76, preventing gate 74 from moving upward. Therefore, gate 74 prevents carrier tape 24 from entering tape transport path 60 in the downstream direction.

[0102] Next, when the carrier tape 24 is to be transported downstream of the gate 74, the unit control section 64 drives the actuator 78 to release the gate 74 from its locked state.

[0103] When the actuator 78 is driven, as shown in FIG. 11(a), the rod 78a extends toward the lever 77, causing the lever 77 to swing counterclockwise. This causes the locking member 76 to move away from the recess 74a of the gate 74, unlocking the gate 74. This allows the gate 74 to move upward. After driving the actuator 78, the unit control unit 64 drives the feed sprocket 62a. This starts the downstream transport of the carrier tape 24, and as shown in FIG. 11(b), the carrier tape 24 moves toward the downstream side of the tape transport path 60 while pushing up the gate 74. The unit control unit 64 stops driving the actuator 78 at an appropriate timing after the leading edge of the carrier tape 24 has passed through the gate 74.

[0104] Referring to FIG. 8, when the carrier tape 24 is transported downstream along the tape transport path 60 and reaches the third transport sprocket 61c, the third sensor PH3 detects the carrier tape 24. The third sensor PH3 transmits a detection signal indicating that the carrier tape 24 has been detected to the unit control unit 64. Upon receiving the detection signal from the third sensor PH3, the unit control unit 64 recognizes that the downstream side of the carrier tape 24 is being transported to the third transport sprocket 61c. The unit control unit 64 then drives the drive unit 62c to move the input sprocket 62a and the tape support unit 62b in the direction of arrow a2. As a result, as shown in FIG. 12 and as already described above, the carrier tape 24 falls from the tape support unit 62b and moves to the bottom surface 60a of the tape transport path 60. When the carrier tape 24 falls from the tape support portion 62b, the gate 74 is pressed against the first support portion 62ba by the compression spring 75, and the locking member 76 is inserted into the recess 74a of the gate 74 by the return spring 79. This causes the gate 74 to enter a locked state.

[0105] The unit control section 64 drives the drive section 62c to move the tape support section 62b, and then returns the tape support section 62b to its original position. The unit control section 64 drives the actuator 78 to retract the rod 78a.

[0106] When the carrier tape 24 falls from the tape support portion 62b, the tape detection piece 71 swings clockwise around the fulcrum 71d, and the plate-shaped portion 71a comes into contact with the pin 72, stopping the swing. This causes the light-shielding portion 71c to move away from the first sensor PH1, so that a detection signal is no longer output to the unit control portion 64. This causes the unit control portion 64 to recognize that the carrier tape 24 is not supported by the tape support portion 62b or that the carrier tape 24 is not present at the first checkpoint.

[0107] 《Exposed part》 Next, the exposed portion 66 will be described with reference to Figure 13. Figure 13 is a side view showing the configuration of the exposed portion 66. Figure 13(a) shows the state in which the carrier tape 24 has passed the exposed portion 66, and Figure 13(b) shows the state in which the carrier tape 24 has turned back through the exposed portion 66. Note that in this specification, "advancing" the carrier tape 24 means that the carrier tape 24 is transported in the downstream direction, and "reverse" the carrier tape 24 means that the carrier tape 24 is transported in the upstream direction.

[0108] Because the top tape 52 is in a film form and is made of a material with extremely low rigidity, the extending portion 52a becomes bent at the leading end 51a of the base tape 51 within the tape transport path 60. In this specification, the state in which the extending portion 52a is bent at the leading end 51a of the base tape 51 and a portion of the extending portion 52a overlaps the carrier tape 24 upstream of the leading end is referred to as "turning up." In this overlapping state, the extending portion 52a of the top tape 52 may or may not contact the top tape 52 attached to the upper surface of the base tape 51. Furthermore, "correcting turning up" and "correcting bending" mean attempting to return the extending portion 52a that was bent at the leading end 51a of the base tape 51 to a state in which it extends forward (downstream) beyond the leading end 51a of the base tape 51, and also include a case in which the extending portion 52a of the top tape 52 is not returned to its fully extended forward position.

[0109] An exposing section 66 is disposed on the inclined portion of the tape transport path 60, diagonally below and upstream of the component removal position 23ba. The exposing section 66 peels the top tape 52 of the carrier tape 24 from the base tape 51 to expose the top surfaces of the components 5 stored in the pockets 53. The exposing section 66 includes a pair of rollers 81, 82 for feeding the top tape and a drive mechanism for driving these rollers 81, 82. The drive mechanism of the exposing section 66 includes a motor as a drive source and a drive transmission mechanism such as gears for transmitting the rotational power of the motor to the rollers 81, 82. The unit control section 64 controls the drive mechanism of the exposing section 66 to rotate, and the rotation of the rollers 81, 82 performs the peeling operation of the top tape 52, which will be described below.

[0110] The rollers 81 and 82 are provided, for example, above the tape transport path 60 and communicate with the tape transport path 60 via an opening 83 that opens on the upper surface 60b side of the tape transport path 60. The extending portion 52a of the top tape 52 of the carrier tape 24 transported from the upstream side along the tape transport path 60 passes through the opening 83 and is drawn into the rollers 81 and 82, and is peeled off from the base tape 51. A newly set carrier tape 24 is fed from the tape inlet 23a of the tape transport path 60 in a state in which the leading end 52b of the top tape 52 is longer than the leading end 51a of the base tape 51 (in a state in which the leading end 52b has the extending portion 52a). When the leading end of the carrier tape 24 reaches the opening 83, the extending portion 52a of the top tape 52 is captured by the exposed portion 66.

[0111] That is, exposed portion 66 pinches and pulls in extended portion 52a at the tip of top tape 52 between rollers 81, 82. As a result, top tape 52 is peeled off from base tape 51 of carrier tape 24. The peeled top tape 52 is fed in a direction away from base tape 51. In the following description, after top tape 52 is peeled off from base tape 51, base tape 51 from which top tape 52 has been peeled off will also be referred to as carrier tape 24.

[0112] A third sensor PH3 is disposed downstream of the position where the exposed portion 66 is disposed. The third sensor PH3 is, for example, a transmission detection optical sensor that detects the carrier tape 24 transported along the tape transport path 60. The detection result by the third sensor PH3 is sent to the unit control unit 64. Alternatively, the leading end of the carrier tape 24 may be detected by providing a dog that can mechanically come into contact with the leading end of the carrier tape 24 and using an optical sensor to detect the displacement of the dog that occurs when the carrier tape 24 comes into contact with the dog. Using a method that detects the displacement of the dog with an optical sensor makes it possible to reliably detect the carrier tape 24 even when the carrier tape 24 is made of a light-transmitting material.

[0113] An air nozzle 84 that sprays air is arranged on the bottom surface 60a side of the tape transport path 60 at a position facing the opening 83, with the air spraying direction facing the opening 83. The air nozzle 84 is an ejection unit that ejects air, and the ejected air is directed at the extending portion 52a of the top tape 52 located near the opening 83, and the force of the ejected air moves the extending portion 52a of the top tape 52 toward the exposed portion 66. In other words, the air nozzle 84 helps the exposed portion 66 to capture the top tape 52 and guides the leading end of the top tape 52 to the exposed portion 66. Air is supplied to the air nozzle 84 from an air supply unit (not shown).

[0114] The unit control unit 64 controls the air supply unit, so that air can be sprayed from the air nozzle 84 toward the exposed portion 66 at any timing. In this embodiment, the unit control unit 64 controls the air nozzle 84 to spray air when the curl of the top tape 52 is corrected and the extended portion 52a reaches a position where it can be captured by the exposed portion 66. For example, when the third sensor PH3 detects the leading end of the carrier tape 24, the third transport sprocket 61c may send the carrier tape 24 upstream a predetermined distance or a predetermined time, and then spray air. As the carrier tape 24 is moved in the reverse direction for a predetermined distance or a predetermined time, the curl of the top tape 52 is corrected and the extended portion 52a is moved below the opening 83.

[0115] Air is sprayed from the air nozzle 84 onto the extending portion 52a, thereby pressing the extending portion 52a against one of the rollers 81 located downstream. Then, the rollers 81 and 82 are rotated in the directions of the arrows shown in FIG. 14(a), and the extending portion 52a pressed against the roller 81 is sandwiched and captured between the one roller 81 and the other roller 82. Then, the rollers 81 and 82 continue to rotate, and the top tape 52 is pulled in a direction away from the base tape 51, thereby peeling the top tape 52 from the base tape 51.

[0116] At this time, the jetting direction of the air nozzle 84 is set so that the jetted air hits the extending portion 52a from below the carrier tape 24.

[0117] 8, the unit control unit 64 is communicatively connected to the drive unit 61d, the exposure unit 66, and the third sensor PH3, and controls the drive unit 61d and the exposure unit 66. That is, the unit control unit 64 controls the third transport sprocket 61c, thereby executing a tape transport operation in which the carrier tape 24 is transported along the tape transport path 60. At this time, the unit control unit 64 is able to control the transport timing and transport amount of the carrier tape 24.

[0118] Furthermore, the unit control unit 64 controls the rollers 81, 82 and the air supply unit based on the detection signal of the third sensor PH3, thereby performing a peeling operation to peel the top tape 52 from the base tape 51 of the carrier tape 24. In this peeling operation, air is sprayed from the air nozzle 84, causing the top tape 52 to be captured by the exposed portion 66.

[0119] An operation unit is communicatively connected to the unit control unit 64, and the unit control unit 64 is further communicatively connected to the main body unit 2 of the component mounting device 1. The tape transport operation and tape feeding operation described above are performed by operation commands input from the operation unit and control commands transmitted from the main body unit 2.

[0120] Next, a tape peeling method for peeling the top tape 52 from the base tape 51 of the carrier tape 24 in the component supply unit 23 configured as described above will be described with particular reference to FIGS.

[0121] The carrier tape 24 inserted into the tape inlet 23a is transported downstream along the tape transport path 60 by the transport sprocket 62a of the tape transport unit 62. When the carrier tape 24 reaches the third transport sprocket 61c of the tape transport unit 61 located downstream of the tape transport path 60 (FIG. 15(b)), the carrier tape 24 is transported thereafter by the tape transport unit 61. As the carrier tape 24 is transported downstream along the tape transport path 60, the top tape 52 curls up. During this tape transport, the rollers 81 and 82 at the exposed portion 66, which is located on the inclined portion of the tape transport path 60, are rotating in a direction that allows them to pinch and capture the top tape 52.

[0122] During this tape transport process, a detection step is performed in which the third sensor PH3 detects the leading end of the carrier tape 24 transported along the tape transport path 60, and this detection result is sent to the unit control unit 64. Then, based on this detection result, a correction step is performed in which the curling of the top tape 52 is corrected. The correction step is performed by the tape transport unit 61. After the curling of the top tape 52 is corrected, a peeling step is performed in which the top tape 52 is peeled off from the carrier tape 24 by an exposing portion 66 provided upstream of the tape transport path 60. During this peeling step, a gas injection step is performed in which air, which is a gas for capturing the extended portion 52a of the top tape 52 in the exposed portion 66, is injected toward the exposed portion 66 by an air nozzle 84, which is an injection unit.

[0123] When the extension portion 52a (tip portion) of the top tape 52 reaches a position where it can be peeled off by the exposed portion 66, the unit control portion 64 controls the air supply portion to execute the gas injection process. As a result, air injected from the air nozzle 84 is blown onto the extension portion 52a of the carrier tape 24.

[0124] 13(a), the extension portion 52a of the top tape 52 extending from the tip 51a of the base tape 51 is bent downward from the base tape 51, or the extension portion 52a is bent upward from the base tape 51. Even if air is sprayed from the air nozzle 84 onto the top tape 52 in this state, the extension portion 52a cannot be blown up, and therefore the extension portion 52a of the top tape 52 cannot be guided to the exposed portion 66.

[0125] 13(a), the third transport sprocket 61c advances the carrier tape 24 so that the tip of the extension 52a of the top tape 52 is located downstream of the air nozzle 84. The unit control unit 64 may control the third transport sprocket 61c to transport the carrier tape 24 until a detection signal for the carrier tape 24 is received from a third sensor PH3 that is located downstream of the air nozzle 84.

[0126] Next, when the third sensor PH3 detects the carrier tape 24, the unit control unit 64, based on this detection signal, stops feeding of the carrier tape 24 and controls the third transport sprocket 61c to reverse the carrier tape 24, i.e., to transport the carrier tape 24 toward the tape inlet 23a. This causes the third transport sprocket 61c to rotate in the reverse direction, and the carrier tape 24 moves backward a predetermined distance upstream, as shown in Figure 13(b).

[0127] 13(b), when the third transport sprocket 61c feeds the carrier tape 24 in the reverse direction, the curled-up extension 52a of the top tape 52 is straightened and the extended portion 52a of the top tape 52 is straightened. To achieve this state, the carrier tape 24 is detected by the third sensor PH3, and then the carrier tape 24 is fed in the reverse direction for a predetermined time measured by a timer, thereby correcting the curled-up top tape 52.

[0128] After feeding the carrier tape 24 backward for a predetermined time, the unit control unit 64 again feeds (forwards) the carrier tape 24 forward for a predetermined distance (predetermined time), thereby positioning the extension portion 52a of the top tape 52 below the center of the exposed portion 66 (between rollers 81 and 82), as shown in Figure 13(b).

[0129] At this timing, the unit control unit 64 injects air from the air nozzle 84, blowing the leading end 52b of the top tape 52 against the rollers 81 and 82, sending the extended portion 52a of the top tape 52 to the exposing portion 66, and the rollers 81 and 82 rotate while sandwiching the top tape 52, as shown in FIG. 14(a). In this way, the top tape 52 can be peeled off completely automatically from the base tape 51. As shown in FIG. 14(b), when the carrier tape 24 advances further, the rollers 81 and 82 also rotate accordingly, peeling off the top tape 52 and exposing the top surfaces of the components 5 stored in the pockets 53 of the carrier tape 24.

[0130] In this way, curling of the top tape 52 can be corrected simply by reversing the carrier tape 24. When the carrier tape 24 is reversed, the air in the tape transport path 60 hits the extending portion 52a of the top tape 52, causing the base tape 51 to move upstream relative to the leading end 52b of the top tape 52. When curling of the top tape 52 is corrected by reversing the carrier tape 24, it is necessary to correct the curling of the top tape 52 upstream of the center of the exposed portion 66 that captures the leading end of the top tape 52.

[0131] The exposed components 5 are transported together with carrier tape 24 by tape transport unit 61 to an opening formed downstream, i.e., component removal position 23ba (see FIGS. 16(a) and 16(b)). An opening is formed at a position corresponding to component removal position 23ba.

[0132] Next, the carrier tape transport operation by the component supply unit 23 will be described with reference to FIGS.

[0133] See FIG. 15(a). The worker inserts the carrier tape 24 along the tape support portion 62b arranged at the tape entrance 23a of the component supply unit 23 whose lamp 23f is flashing. After inserting the carrier tape 24, the worker presses the switch 23g of the component supply unit 23. If the current tape 24a is located downstream of the tape transport path 60, the tape loading portion 62 loads the carrier tape 24 while the gate 74 of the gate unit 63b is locked. When the carrier tape 24 is detected by the first sensor PH1, the loading sprocket 62a is stopped. If the worker has inserted the carrier tape 24 to the position detected by the first sensor PH1, the tape loading portion 62 does not operate. In either case, the carrier tape 24 cannot advance beyond the gate 74.

[0134] If the operator presses switch 23g and there is no carrier tape 24 downstream of tape transport path 60, pressing switch 23g unlocks gate 74, and in this state, tape feed unit 62 feeds carrier tape 24. As a result, the leading edge of carrier tape 24 pushes up gate 74 and is sent into tape transport path 60. As shown in FIG. 15(b), when carrier tape 24 is fed to a position where it hits the pin of third transport sprocket 61c, feeding by feed sprocket 62a stops. Carrier tape 24 is fed further downstream by third transport sprocket 61c, and when it is detected by third sensor PH3, tape feed unit 61 performs an operation to capture top tape 52 at exposed portion 66.

[0135] When the exposed portion 66 captures the top tape 52, the exposed portion 66 and the third transport sprocket 61c transport the carrier tape 24 further downstream while peeling off the top tape 52. When the pin of the second transport sprocket 61b is inserted into the feed hole 54 of the carrier tape 24, the drive portion 61d drives the second transport sprocket 61b to position the leading pocket 53 of the carrier tape 24 at the component removal position 23ba, as shown in FIG.

[0136] Next, a path change is performed in the tape entrance section 62. As shown in FIG. 16(b), the carrier tape 24 passing through the tape entrance section 62 drops out of the tape entrance section 62 due to the path change and moves to the bottom surface 60a of the tape transport path 60 below. The path change is performed when the carrier tape 24 is engaged with the second transport sprocket 61b and the third transport sprocket 61c of the tape transport section 61. When the path change is performed, the gate 74 moves downward and enters a locked state.

[0137] 17(a), the worker can insert the next carrier tape 24 to be used (next tape 24b) into the tape loading section 62 that has become vacant due to the path change. The method of inserting the carrier tape 24 into the tape loading section 62 is the same as the method already described above.

[0138] As shown in FIG. 17(b), when a component shortage is detected in the carrier tape 24 and the second sensor PH2 detects the passage of the final end of the carrier tape 24, the tape transport unit 61 discharges the carrier tape 24 (tape discharge). If the passage of the final end of the carrier tape 24 has not been detected at the time the component shortage is detected, a final end search is performed, and then the tape is discharged. When the current tape 24a has been discharged, the gate 74 is unlocked, and in this state the tape feed unit 62 feeds the next tape 24b. As a result, the leading edge of the next tape 24b pushes up the gate 74 and is sent into the tape transport path 60. When the next tape 24b is transported to a position where it hits the pin of the third transport sprocket 61c, the most upstream of the tape transport unit 61, the feed by the feed sprocket 62a stops. After this, a path change is performed, and the next tape 24b is transported as the current tape 24a.

[0139] Tape cassette Next, the tape cassette 22 will be described with reference to Figure 18. Figures 18(a), 18(b), and 18(c) are cross-sectional side views of the tape cassette 22 showing how the roll 25 of the carrier tape 24 is inserted into and removed from the tape cassette 22 used as the storage cassette 22B.

[0140] When storing the roll 25 in the tape cassette 22, with the shutter 42 in the open position, the roll 25 is inserted through the opening 41b on the front of the storage section 41 (arrow shown in FIG. 18(a)), and the operating lever 86 is moved downward (arrow shown in FIG. 18(b)). This moves the shutter 42 from the open position to the closed position, and the opening 41b of the storage section 41 is closed by the shutter 42, so that the roll 25 is stored in the tape cassette 22 (FIG. 18(b)).

[0141] On the other hand, when removing the roll 25 stored in the tape cassette 22 or when using the carrier tape 24 pulled out from the roll 25 stored in the storage cassette attachment section 39 in the component supply unit 23, the operating lever 86 is moved upward (arrow shown in FIG. 18(c)). This moves the shutter 42 from the closed position to the open position, opening 41b of the storage section 41 and allowing the roll 25 to be removed from the storage section 41 (arrow shown in FIG. 18(c)).

[0142] Thus, in this embodiment, the tape cassette 22 as a storage device is configured to include a storage section 41 having a space 41a for storing the roll body 25 and an opening 41b at the front through which the roll body 25 can be taken in and out, and a shutter 42 as a regulating section that is displaceable between a first position (closed position) that blocks at least a portion of the opening 41b to regulate the roll body 25 stored in the space 41a from moving through the opening 41b to the outside of the storage section 41, and a second position (open position) that allows the roll body 25 stored in the storage space to move through the opening 41b to the outside of the storage section 41.

[0143] 19(a) and 19(b) are side cross-sectional views of a portion of the component supply unit 3 showing the movement of the roll body 25. When the component supply unit 23 retracts the carrier tape 24 in the process of loading the storage cassette 22B into the storage cassette loading section 39, if the retracted carrier tape 24 is the current tape 24a, it continues to transport the carrier tape 24 to load the components 5. If the retracted carrier tape 24 is the next tape 24b, it causes the next tape 24b to wait until it detects that the end of the current tape 24a has passed the third checkpoint in the component supply unit 23. When the end of the current tape 24a has passed the third checkpoint, the storage section 41 of the receiving cassette 22A is empty. When the component supply unit 23 starts transporting the next tape 24b, the roll 25 of the next tape 24b stored in the storage cassette 22B is pulled by the next tape 24b being transported by the component supply unit 23 and rolls forward, moving into the storage section 41 of the receiving cassette 22A located in front of it (Figure 19(a) → Figure 19(b)).

[0144] When the roll 25 stored in storage cassette 22B moves into receiving cassette 22A, storage cassette 22B becomes empty. The empty storage cassette 22B is removed from cart 21 (cassette mounting section 46a) so that the next roll 25 (storage cassette 22B) of carrier tape 24 to be used can be mounted on cart 21. Then, when the supply of components 5 by component supply unit 23 has progressed, the worker mounts a new tape cassette 22 in cassette mounting section 46a in the manner described above.

[0145] Next, a configuration of a component mounting system 91 including a plurality of component mounting devices 1 will be described with reference to Fig. 20. Fig. 20 is a diagram showing an example of the configuration of a component mounting system.

[0146] The component mounting system 91 includes a management device 92 , a cassette preparation station 93 , a setup station 94 , one or more component mounting devices 1 , a portable information terminal 95 , and a network 96 .

[0147] 《Management device》 The management device 92 collectively manages production information of the cassette preparation station 93, the setup station 94, and one or more component mounting devices 1. The management device 92 is, for example, a host computer and can be configured with an integrated circuit such as a microcomputer, CPU, MPU, GPU, DSP, FPGA, or ASIC. The functions of the management device 92 are realized by combining hardware and software. The management device 92 realizes predetermined functions by reading data and programs stored in a memory unit 105 and performing various arithmetic operations. The management device 92 includes a cassette management unit 101, a production record collection unit 102, a component replenishment instruction unit 103, a trace information aggregation unit 104, and a memory unit 105.

[0148] The cassette management unit 101 generates and updates cassette management information 111 that associates cassette ID information of a tape cassette 22 with component information of the components 5 housed in the tape cassette 22. The cassette management information 111 is stored in the storage unit 105. The cassette management information 111, an example of which is shown in FIG. 25, includes component IDs as component information, as well as the number of components (remaining number). In addition, although not shown in FIG. 25, the cassette management information 111 also includes location information that identifies the cassette mounting location and location, and information related to the status. The cassette management unit 101 updates the number of components based on information about the number of components used in production notified by the component mounting device 1. The cassette management unit 101 also updates the information related to the cassette location and status based on detection of the presence or absence of a tape cassette 22 in the cassette mounting unit 46a.

[0149] The production record collection unit 102 collects the production record of the board 4 at each component mounting device 1.

[0150] The parts replenishment instruction unit 103 issues an instruction to replenish the next tape 24b.

[0151] The trace information collecting unit 104 collects the trace information created by each component mounting device 1 and generates serialized trace information.

[0152] The memory unit 105 stores information related to production and information sent from the cassette preparation station 93, the setup station 94, one or more component mounting devices 1, and the portable information terminal 95. The memory unit 105 also stores information necessary for the operation and processing of the cassette preparation station 93, the setup station 94, and one or more component mounting devices 1. The memory unit 105 stores cassette management information 111, a production program 112, production results 113, and aggregated trace information 114. The memory unit 105 can be realized by, for example, a hard disk drive (HDD), an SSD, RAM, DRAM, a ferroelectric memory, a flash memory, a magnetic disk, or a combination of these.

[0153] The cassette preparation station 93 is a structure that removes the roll body 25 wound around the reel 27 (see FIG. 24) and places it in the tape cassette 22. The cassette preparation station 93 includes a code reading unit 121 and a reader / writer 122.

[0154] The setup station 94 is a structure for performing setup for the next production outside the component mounting device 1. The setup station 94 includes a docking section 131 that can be docked with the component supply section 3.

[0155] The portable information terminal 95 communicates wirelessly with the management device 92, allowing the worker to check the production information held by the management device 92 while carrying the portable information terminal 95. Furthermore, instructions for off-site setup are sent from the parts replenishment instruction unit 103 to the portable information terminal 95, allowing the worker to perform off-site setup work in accordance with those instructions. The portable information terminal 95 is, for example, a tablet terminal or a smartphone.

[0156] The network 96 connects the management device 92, the cassette preparation station 93, the setup station 94, and the component mounting device 1 so that they can communicate with each other.

[0157] Next, the configuration of the setup station 94 will be described with reference to Fig. 21. The setup station 94 further includes a connector 132, a monitor 133, an operation unit 134, and a code reader 135.

[0158] The docking unit 131 includes a processing unit 136 and a storage unit 138. The component supply unit 3, which is movable by a carriage 21, can be attached to and detached from the docking unit 131. The docking unit 131 can communicate with the management device 92 via the network 96. In addition, a connector 21a of the component supply unit 3 is connected to a connector 132 of the setup station 94, and the docking unit 131 and the component supply unit 23 attached to the carriage 21 can communicate with each other via the connector 21a.

[0159] The processing unit 136 has a setup unit 137. The setup unit 137 will be described in detail later. The processing unit 136 can be realized by an integrated circuit configured with semiconductor elements or the like. The processing unit 136 can be configured with circuits such as a microcomputer, CPU, MPU, GPU, DSP, FPGA, or ASIC. The functions of the processing unit 136 may be configured with hardware alone, or may be realized by combining hardware and software. The processing unit 136 realizes predetermined functions by reading data and programs stored in the storage unit 138 and performing various arithmetic processing.

[0160] The storage unit 138 has connection information 138a. The connection information 138a is information relating to the correspondence between ports, and is information relating to the correspondence between ports P01 to P22 to which the component supply unit 3 is connected and ports P23 to P66 that communicate with wireless tags. For example, the storage unit 138 has information in which port P01 is grouped with ports P23 and P24. The storage unit 138 can be realized by, for example, a hard disk drive (HDD), an SSD, RAM, DRAM, a ferroelectric memory, a flash memory, a magnetic disk, or a combination of these.

[0161] The component supply unit 3 includes a relay board 40 assigned to port numbers P01 to P66. The reader / writers 29a, 29b and the unit control unit 64 of the component supply unit 23 can communicate with the setup station 94 and the management device 92 via the relay board 40.

[0162] The production program 112 stored in the memory unit 105 of the management device 92 includes setup information. The setup information is information that associates a component supply position number assigned to the cassette mounting unit 46a with the component to be supplied. The component supply position number is information that corresponds to the address of the supply unit mounting unit 31b in the supply unit base 31. Therefore, in the setup station 94, before production, an operation is performed to set the carrier tape 24 containing the components specified in the setup information in the component supply unit 23 mounted in the supply unit mounting unit 31b specified by the component supply position number in the setup information.

[0163] Next, with reference to FIG. 22, the configuration when the component supply unit 3 is docked to the main body unit 2 of the component mounting device 1 will be described.

[0164] The main body control unit 17 includes a processing unit 141 and a storage unit 142. The main body control unit 17 can be realized by an integrated circuit configured with semiconductor elements or the like. The main body control unit 17 can be configured with circuits such as a microcomputer, CPU, MPU, GPU, DSP, FPGA, or ASIC. The functions of the main body control unit 17 may be configured with hardware alone, or may be realized by combining hardware and software. The main body control unit 17 realizes predetermined functions by reading data and programs stored in the storage unit 142 and performing various arithmetic processing.

[0165] The processing unit 141 includes an operation control unit 143 , a component shortage determination unit 144 , an information update unit 145 , a supply unit state detection unit 146 , a component replenishment support unit 147 , and a trace information creation unit 148 .

[0166] The operation control unit 143 controls a series of movements for mounting the components 5 on the board 4, and controls the operations of the board transport unit 12, the mounting head 13, and the head moving mechanism , for example.

[0167] The out-of-component determination unit 144 determines whether or not there is an out-of-component situation among the components 5 supplied from the component supply unit 23. The out-of-component determination unit 144 determines that there is an out-of-component situation when the nozzle 13a of the mounting head 13 fails to pick up a component 5 a predetermined number of times in succession.

[0168] The information update unit 145 updates the information recorded in the wireless tag 28 in accordance with replacement of the carrier tape 24. Updating the information includes erasing the information and overwriting it with new information.

[0169] The supply unit state detection unit 146 detects that the next tape 24b can be inserted into the tape carry-in portion 62 in the component supply unit 23, and transmits a signal indicating that component replenishment is possible to the component replenishment instruction unit 103. A component supply unit 23 that is possible to replenish components has not inserted the next tape 24b into the tape carry-in portion 62, and is in a state where the next tape 24b can be inserted.

[0170] The component replenishment support unit 147 receives information specifying the component supply unit 23 to be replenished from the component replenishment instruction unit 103, and flashes the lamp 23f of the component supply unit 23 to notify the worker of the component supply unit 23 to be replenished.

[0171] The tracing information creation unit 148 creates tracing information for the board 4 on which each component 5 is mounted, based on the tracing information for each component 5 stored in the wireless tag 28. For example, the tracing information creation unit 148 creates tracing information by associating the ID of the board 4 with the component information for each component 5 mounted on the board 4. The created tracing information for the board 4 is stored in the storage unit 142 as individual tracing information 153.

[0172] The storage unit 142 stores a production program 151, connection information 152, and individual trace information 153. The storage unit 142 can be realized by, for example, a hard disk (HDD), an SSD, RAM, DRAM, a ferroelectric memory, a flash memory, a magnetic disk, or a combination of these. The storage unit 142 stores connection information 152 that associates one port of the reader / writer 29a and one port of the reader / writer 29b with a port of one unit base side connector 30. The main body control unit 17 selects a communication destination based on the ports individually assigned to the multiple unit base side connectors 30, the multiple reader / writers 29a, and the multiple reader / writers 29b.

[0173] The production program 151 is a program required to operate the component mounting device 1. The production program 151 is downloaded from the production program 112 stored in the storage unit 105 of the management device 92 and stored in the storage unit 142. In addition to the above-mentioned setup information 151a (the setup information of the production program 112), the production program 151 also includes information such as the component mounting positions (coordinates) on the board 4, the names and mounting order of the components 5 to be mounted there.

[0174] As shown in Fig. 23, the connection information 152 is information that associates the component supply position number assigned to the supply unit mounting section 31b with the connection port. As shown in Fig. 4, the component supply unit 23 sets the carrier tape 24 that is fed out from the tape cassette 22 that is attached to the cassette mounting section 46a that is located in the same juxtaposition as the supply unit mounting section 31b to which the component supply unit 23 itself is attached. For this reason, the component mounting device 1 assigns a common component supply position number to the supply unit mounting section 31b and the cassette mounting section 46a that are located in the same juxtaposition. The connection information 138a also includes this component supply position number.

[0175] The information update unit 145 can know in which group the component supply unit 23, the reader / writers 29a and 29b, and the connection port are grouped, based on the connection information 152. By referring to the component supply position number, the information update unit 145 can send component information to be copied from the reader / writer 29a serving as the first wireless communication unit to the reader / writer 29b serving as the second wireless communication unit, which are grouped together.

[0176] Cassette Preparation Station Next, the processing performed in the cassette preparation station 93 will be described with reference to Fig. 24. Fig. 24 is a diagram showing the configuration of the cassette preparation station 93. In the cassette preparation station 93, component information of the roll body 25 is written to the wireless tag 28 of the tape cassette 22.

[0177] The component information will now be described. The component information is information about the components packed in the carrier tape 24 of the roll 25, and includes information such as the component name, component type, the number of components in the unopened roll 25, the component manufacturer and country of manufacture, the date of manufacture, the serial number, the lot number, the pitch of the pockets 53 on the carrier tape 24, and the material of the carrier tape 24. This information is acquired from a barcode or two-dimensional code (hereinafter referred to as a code) printed on a label issued by the component manufacturer. The component information also includes information that can identify components on a per-roll basis. This is identification information issued for the convenience of component inventory management at the factory of the user who uses the component mounting device 1, such as a component ID (sometimes called a reel ID). When the reel 27 storing the roll 25 is received, the user issues a component ID and affixes a label on which a code recording the component ID is printed to the reel 27 for management.

[0178] At the cassette preparation station 93, an operator removes the roll 25 from the reel 27 and stores it in the tape cassette 22. The component information of the roll 25 is contained in a code 27a printed on a label attached to the reel 27. The operator uses a code reading unit 121 in the cassette preparation station 93 to read the component information contained in the code 27a on the reel 27. The read component information is sent to the cassette management unit 101 of the management device 92. The code reading unit 121 is a reader that reads code information corresponding to the type of code, and is, for example, a barcode reader or a camera.

[0179] Furthermore, in the cassette preparation station 93, the reader / writer 122 communicates with the wireless tag 28 attached to the tape cassette 22 that accommodates the roll body 25, writes the component information read by the code reading unit 121 to the wireless tag 28, and acquires the cassette ID of the tape cassette 22 stored in the wireless tag 28. The acquired cassette ID is sent to the cassette management unit 101. The cassette ID is information that can individually identify the tape cassette 22.

[0180] The cassette management unit 101 generates cassette management information 111 that associates the component information sent from the code reading unit 121 with the cassette ID sent from the reader / writer 122, and stores the generated management information 111 in the memory unit 105.

[0181] Setup Station Next, the processing performed in the setup station 94 will be described with reference to Fig. 26. Fig. 26 is a diagram showing the configuration of the setup station 94.

[0182] The setup work is the work of setting up the component supply unit 23 used in the manufacture of the board 4 on which the components 5 are to be mounted and the tape cassette 22 storing the components 5 in the component supply unit 3. The setup work performed for a spare component supply unit 3 that is not attached to the component mounting device 1 is called "external setup work," and the setup work performed for a component supply unit 3 that is attached to the component mounting device 1 is called "internal setup work." The setup work performed at the setup station 94 is external setup work, which will be explained below.

[0183] By mounting the component supply unit 23 and tape cassette 22 on the cart 21 and connecting the cart 21 to the docking section 131 of the setup station 94, it is possible to carry out off-site setup work for the component supply unit 23 and tape cassette 22. After the off-site setup work is completed, the component supply unit 23 and tape cassette 22 can be moved together with the cart 21 and connected to the main body section 2 of the component mounting device 1. This allows the setup work for the component supply section 3 to be completed in advance when changing the type of board 4 to be produced, so that the board 4 to be produced can be changed quickly.

[0184] The setup station 94 is capable of communicating with the component supply unit 23, the receiving cassette 22A, and the storage cassette 22B by connecting the connector 21a of the carriage 21 to the docking section 131.

[0185] The setup unit 137 includes a cassette detection unit 161 , a cassette determination unit 162 , a unit notification unit 163 , a permission unit 164 , and an information update unit 165 .

[0186] When a tape cassette 22 is attached to the receiving cassette attachment portion 38 and the storage cassette attachment portion 39 of the cart 21, the cassette detection portion 161 detects the tape cassette 22 and transmits a detection signal to the cassette determination portion 162. The cassette detection portion 161 detects that the tape cassette 22 has been attached to the cassette attachment portion 46a corresponding to the wireless communication portion 29 when the wireless communication portion 29 changes from a state in which it has not detected the wireless tag 28 to a state in which it has detected the wireless tag 28.

[0187] When the reader / writers 29a, 29b serving as the wireless communication unit 29 detect a wireless tag 28 within their reception range, they output a signal (cassette detection signal) notifying that they are in a state in which they can communicate with the wireless tag 28. The cassette detection unit 161 of this embodiment uses the wireless tag detection function of the reader / writers 29a, 29b to detect that a tape cassette 22 has been loaded into the receiving cassette loading unit 38 or the storage cassette loading unit 39. Furthermore, the cassette detection unit 161 identifies the position (loading location) of the loaded tape cassette 22 based on the cassette detection signal received from the reader / writers 29a, 29b. The cassette detection unit 161 refers to the connection information 152 to identify the component supply position number corresponding to the connection port from which the cassette detection signal has been sent, as information indicating the loading location of the tape cassette 22.

[0188] The cassette determination unit 162 determines whether the loaded tape cassette 22 is the tape cassette 22 that contains the correct carrier tape 24. For example, the cassette determination unit 162 compares the loaded position of the tape cassette 22, component information from the wireless tag 28 of the loaded tape cassette 22, and information defined in the production program 112 to determine whether the loaded tape cassette 22 is correct. The production program 112 stored in the storage unit 105 includes setup information that specifies the components to be placed in the cassette loading unit 46a. If the cassette determination unit 162 determines that the loaded tape cassette 22 is correct, it transmits a correct determination signal to the unit notification unit 163 and the permission unit 164. If the cassette determination unit 162 determines that the loaded tape cassette 22 is incorrect, it transmits an incorrect determination signal, respectively.

[0189] When the unit notification unit 163 receives the correct determination signal, it flashes the lamp 23f of the component supply unit 23 into which the carrier tape 24 should be inserted, notifying the worker that the correct tape cassette 22 has been loaded, and also notifying the worker of the component supply unit 23 into which the carrier tape 24 should be loaded. When the unit notification unit 163 receives the incorrect determination signal, it flashes the lamp 23f of the component supply unit 23 in a different pattern or color than when the unit notification unit 163 receives the correct determination signal, notifying the worker that the incorrect tape cassette 22 has been loaded.

[0190] Upon receiving the positive determination signal, the permission unit 164 sends a permission signal to the component supply unit 23, thereby granting the component supply unit 23 permission to supply the carrier tape 24. Upon receiving the permission signal from the permission unit 164, the component supply unit 23 waits until it is ready to start retracting the carrier tape 24. The worker inserts the carrier tape 24 into the component supply unit 23 whose lamp 23f is flashing due to the positive determination, and presses the switch 23g of that component supply unit 23 to notify that the component replenishment work is complete. The component supply unit 23 starts retracting the carrier tape 24 after confirming two events: receipt of the permission signal and the worker's operation of the switch 23g. If the two events are not confirmed within a predetermined time, the component supply unit 23 does not retract the carrier tape 24. This makes it possible to inform the worker that the carrier tape 24 has been mistakenly inserted into the wrong component supply unit 23, thereby preventing the wrong component from being supplied. In addition, the unit notification unit 163 and the permission unit 164 may be integrated into one configuration, i.e., the command sent from the unit notification unit 163 to the component supply unit 23 to flash the lamp 23f may be used as a permission signal, thereby making the unit notification unit 163 function as the permission unit 164.

[0191] The information update unit 165 updates the information in the wireless tag 28 when the next tape 24b is pulled in and changes to the current tape 24a. When the information update unit 165 updates the information in the wireless tag 28, the cassette management information 111 in the management device 92 is also updated.

[0192] A setup support device 97 is configured by a plurality of wireless communication units 29, a storage unit 105 that stores a production program 112 including setup information, and a setup station 94.

[0193] Next, the setup work for the current tape 24a will be described with reference to Figures 26 to 29. Figure 27 is a flowchart showing the processing (setup work) of the setup unit 137 during the setup work for the current tape 24a. Figures 28 and 29 are explanatory diagrams showing the component supply unit 3 during the setup work for the current tape 24a, and Figures 28(a), (b) and 29(a), (b) are diagrams of each step of the setup work for the current tape 24a.

[0194] 26, the setup section 137 refers to the production program 112 for the mounted boards scheduled for production and displays the type of component supply unit 23 and the component supply position number on the monitor 133. The worker looks at the monitor 133 and mounts the component supply unit 23 in the location corresponding to the relevant component supply position number, as shown in FIG. 28(a). The worker also mounts an empty tape cassette 22 in the receiving cassette mounting section 38 at the position corresponding to the relevant component supply position number.

[0195] Next, as shown in FIG. 28(b), the worker loads the storage cassette 22B containing the roll body 25 of the specified component 5 into the storage cassette loading section 39 based on the setup information displayed on the monitor 133 by the setup section 137.

[0196] When the storage cassette 22B is mounted in the storage cassette mounting portion 39 of the carriage 21, the setup unit 137 detects that the storage cassette 22B has been mounted in step ST1 shown in FIG. 27. Specifically, the reader / writer 29b detects the wireless tag 28 of the storage cassette 22B and communicates with it. The cassette detection unit 161 receives a cassette detection signal from the reader / writer 29b and detects that the storage cassette 22B has been mounted (Yes in step ST1). If the storage cassette 22B is not mounted in the storage cassette mounting portion 39 of the carriage 21, the cassette detection unit 161 does not receive the cassette detection signal from the reader / writer 29b (No in step ST1), and therefore the reader / writer 29b continues to transmit a wireless signal at the communication frequency. When the cassette detection unit 161 detects that the cassette has been mounted, the cassette detection unit 161 identifies the mounting location of the mounted storage cassette 22B in step ST2. When the mounting location of the storage cassette 22B is identified, the information updating unit 165 updates the location information of the cassette management information 111.

[0197] In step ST3, the cassette determination unit 162 reads the component information of the loaded storage cassette 22B from the wireless tag 28 using the reader / writer 29b. Note that the cassette determination unit 162 may identify the cassette loading unit 46a in which the tape cassette 22 is loaded, instead of the cassette detection unit 161. In step ST4, the cassette determination unit 162 refers to the production program 112 to confirm the correspondence between the loading location of the loaded storage cassette 22B and the component information.

[0198] In step ST5, the cassette determination unit 162 determines whether the correspondence between the installation location of the installed storage cassette 22B and the read component information matches the contents of the setup information of the production program 112, i.e., whether a tape cassette 22 containing an appropriate carrier tape 24 has been installed.

[0199] In step ST5, if the cassette determination unit 162 determines that the correspondence between the mounting location and the component information matches the contents of the production program 112 (Yes in step ST5), in step ST6, the unit notification unit 163 flashes the lamp 23f of the component supply unit 23 into which the next tape 24b should be inserted.

[0200] In step ST7, the permission unit 164 transmits a permission signal to the unit control unit 64 to permit the carrier tape 24 to be carried into the component supply unit 23. Furthermore, as shown in FIG. 29(a), when the worker inserts the carrier tape 24 into the tape inlet 23a and presses the switch 23g of the component supply unit 23, a switch signal is transmitted to the unit control unit 64.

[0201] In step ST8, upon receiving two signals, the permission signal from the permission unit 164 and the switch signal from the switch 23g, the unit control unit 64 starts loading of the next tape 24b stored in the storage cassette 22B. The unit control unit 64 also turns off the lamp 23f and outputs a start signal indicating the start of loading of the carrier tape 24 to the setup unit 137. If the unit control unit 64 does not receive these two signals, it puts the loading of the next tape 24b on hold (No in step ST8) and waits for the two signals to arrive.

[0202] When the loading of the next tape 24b begins (Yes in step ST8), the roll 25 stored in the storage cassette 22B is moved from the storage cassette 22B to the empty receiving cassette 22A. When the setup section 137 receives a start signal from the unit control section 64, in step ST9, the information update section 165 updates the component information read from the wireless tag 28 of the storage cassette 22B as the component information of the wireless tag 28 of the receiving cassette 22A, and erases the component information of the wireless tag 28 of the emptied storage cassette 22B. The information update section 165 also updates the cassette management information 111 stored in the memory section 105 of the management device 92. Specifically, the information in the cassette ID field of the storage cassette 22B is copied to the cassette ID field of the receiving cassette 22A, and the information in the cassette ID field of the storage cassette 22B is erased.

[0203] By updating the component information of the wireless tag 28 of the receiving cassette 22A, the component information of the roll body 25 of components 5 stored in the receiving cassette 22A is recorded in the wireless tag 28 of the receiving cassette 22A, so that even when production of the board 4 is stopped midway, the trace information of the roll body 25 in the receiving cassette 22A can be maintained.

[0204] In step ST10, the setup unit 137 determines whether the setup work for all component supply units 23 that require setup of the current tape 24a has been completed. If the setup unit 137 determines that the setup work for the current tape 24a has not been completed (No in step ST10), the process is repeated from step ST1. If the setup unit 137 determines that the setup work for the current tape 24a has been completed (Yes in step ST10), the setup unit 137 displays a message regarding the setup work for the current tape 24a on the monitor 133 of the setup station 94 to notify the operator that the setup work has been completed.

[0205] Also, in step ST5, if the cassette determination unit 162 determines that the correspondence between the mounting location and the part information does not match the contents of the production program 112 (No in step ST5), in step ST11, a confirmation message is displayed on the monitor 133 of the setup station 94 to instruct the worker to confirm the mounting location.

[0206] In step ST12, the cassette determination unit 162 detects whether the storage cassette 22B for which the confirmation message is displayed has been removed. If the cassette determination unit 162 detects that the storage cassette 22B for which the confirmation message is displayed has been removed (Yes in step ST12), it performs the process of step ST10. If the cassette determination unit 162 does not detect that the storage cassette 22B for which the confirmation message is displayed has been removed (No in step ST12), it returns to step ST11 and continues to display on the monitor 133 the confirmation message that prompts the operator to check the installation location.

[0207] Next, the setup work for the next tape 24b will be described with reference to Figures 30 and 31. Figure 30 is a flowchart showing the processing (setup work) of the setup unit 137 during the setup work for the next tape 24b. Figure 31 is an explanatory diagram showing the component supply unit 3 during the setup work for the next tape 24b, and Figures 31(a) and (b) are diagrams of each step of the setup work for the next tape 24b.

[0208] 31(a), receiving cassette 22A containing current tape 24a that has been pulled into tape transport path 60 of component supply unit 23 is already attached to receiving cassette attachment portion 38 of carriage 21. The worker removes empty storage cassette 22B from storage cassette attachment portion 39 and, based on the setup information displayed on monitor 133 by setup portion 137, attaches storage cassette 22B containing roll 25 of predetermined components 5 to storage cassette attachment portion 39.

[0209] In the flowchart of FIG. 30, steps ST21 to ST27, step ST30, and step ST31 are the same processes as steps ST1 to ST7, step ST11, and step ST12 in the flowchart of FIG. 27, and therefore description thereof will be omitted.

[0210] The setup section 137 executes steps ST21 to ST27 as shown in Figures 31(b) and 30. In step ST27, when the worker inserts the carrier tape 24 into the tape loading section 62 and presses the switch 23g of the component supply unit 23, a switch signal is transmitted to the unit control section 64. As shown in Figure 31(c), upon receiving the switch signal from the switch 23g, the unit control section 64 drives and rotates the loading sprocket 62a to advance the next tape 24b stored in the storage cassette 22B. The unit control section 64 also turns off the lamp 23f.

[0211] As the next tape 24b advances, the leading edge of the next tape 24b comes into contact with the contact portion 71b of the tape detection piece 71 and the gate 74, and is detected by the first sensor PH1. In this way, the unit control unit 64 transports the next tape 24b to a position where it is detected by the first sensor PH1, and the leading edge of the next tape 24b is maintained in contact with the gate 74.

[0212] In step ST28, the setup unit 137 determines whether the work by the worker has been completed. When the setup unit 137 receives two signals, the switch signal from the switch 23g and the detection signal from the first sensor PH1, it determines that the work by the worker has been completed. If the setup unit 137 does not receive these two signals, it determines that the work by the worker has not been completed (No in step ST28), and performs step ST28 again after a predetermined time has elapsed.

[0213] When the setup unit 137 determines that the work by the worker is complete (Yes in step ST28), in step ST29, the setup unit 137 determines whether the setup work for the next tape 24b of all component supply units 23 that require setup of the next tape 24b has been completed. When the setup unit 137 determines that the setup work for the next tape 24b has not been completed (No in step ST29), the processing is repeated again from step ST1. When the setup unit 137 determines that the setup work for the next tape 24b has been completed (Yes in step ST29), the setup unit 137 displays a message regarding the setup work for the next tape 24b on the monitor 133 of the setup station 94 to notify the worker that the setup work for the next tape 24b has been completed.

[0214] <<Information update when changing tapes in component mounting equipment>> Next, a configuration in which the current tape 24a is used up during a component mounting operation and the next tape 24b is supplied as a new current tape 24a in the component mounting device 1 will be described with reference to Fig. 32. Fig. 32 is an explanatory diagram showing the configuration of the component mounting device 1.

[0215] The out-of-component determination unit 144 of the main body control unit 17 determines whether the current tape 24a has run out of components. A series of empty pockets 53 is located downstream of the end of the carrier tape 24. Therefore, if the nozzle 13a of the mounting head 13 fails to pick up components 5 from the current tape 24a a predetermined number of times in succession, the out-of-component determination unit 144 determines that the current tape 24a has run out of components.

[0216] Furthermore, in addition to the above-described conditions for consecutive failures in component removal, the determination may also be based on the number of remaining components in the cassette management information 111. Because there is a possibility of misjudgment based on the above-described conditions alone, the accuracy of the determination can be improved by also taking into account the number of remaining components. When the nozzle 13a of the mounting head 13 fails to remove components 5 from the current tape 24a a predetermined number of times in succession, the component out-of-component determination unit 144 determines that there is a component out-of-component condition based on the above-described conditions if the number of remaining components is a predetermined number or less, and determines that there is no component out-of-component condition if the number of remaining components is large. If it is determined that there is no component out-of-component condition, it is treated as a simple malfunction. Furthermore, the component out-of-component determination unit 144 may determine whether the current tape 24a is out of components based solely on the number of remaining components in the cassette management information 111.

[0217] When the component shortage determination unit 144 determines that the current tape 24a is out of components, the operation control unit 143 ejects the emptied current tape 24a and also controls the drive unit 62c of the component supply unit 23 to switch the next tape 24b as the next current tape 24a.

[0218] The information update unit 145, like the information update unit 165, updates the information in the wireless tag 28 when the next tape 24b is pulled in and changes to the current tape 24a. When the information update unit 145 updates the information in the wireless tag 28, the cassette management information 111 in the management device 92 is also updated.

[0219] Next, the operation of updating information due to tape switching in the component mounting device 1 will be described with reference to Fig. 33. Fig. 33 is a flowchart showing the flow of information updating processing in the component mounting device 1.

[0220] First, a component supply step is performed in which the current tape 24a of the receiving cassette 22A is transported to supply the components 5 to the component pick-up position 23ba. Eventually, all the components packed on the current tape 24a are supplied, and the current tape 24a runs out of components.

[0221] When the component out-of-stock determination unit 144 determines that the current tape 24a has run out of components, it transmits a determination signal and the installation location (component supply position number) of the component supply unit 23 where the current tape 24a is set to the operation control unit 143. In step ST32, upon receiving the determination signal, the operation control unit 143 transmits a tape switching command to the corresponding component supply unit 23. Upon receiving the tape switching command, the component supply unit 23 advances the next tape 24b to start a switching operation to change the next tape 24b to the current tape 24a (Yes in step ST32). This executes a tape loading step in which the component supply unit 23 starts loading the next tape 24b from the storage cassette 22B. If the operation control unit 143 does not receive a determination signal from the component out-of-stock determination unit 144, it does not send a tape switching command to the component supply unit 23, so the switching operation to change the next tape 24b to the current tape 24a is not initiated (Yes in step ST32), and the component supply unit 23 continues the component supply step from the current tape 24a.

[0222] In step ST33, the information update unit 145 identifies the component supply position number of the component supply unit 23 where the switching operation of the next tape 24b has started, from the mounting location (component supply position number) transmitted from the component shortage determination unit 144. Furthermore, the information update unit 145 recognizes that the component supply unit 23 has started transporting the carrier tape 24 from the storage cassette 22B, from the signal indicating the mounting location transmitted from the component shortage determination unit 144. The information update unit 145 further identifies the reader / writer 29a and reader / writer 29b associated with the identified component supply unit 23, based on the connection information 152.

[0223] In step ST34, the information update unit 145 copies the component information read from the wireless tag 28 of the storage cassette 22B as component information for the wireless tag 28 of the receiving cassette 22A. In this case, the component information is copied using the reader / writer 29a and the reader / writer 29b connected to the connection port belonging to the component supply position number identified in step ST33. As long as the information to be copied includes component information, all of the information contained in the wireless tag 28 of the receiving cassette 22A may be copied, or only part of the component information may be copied.

[0224] In this way, in conjunction with the component supply unit 23 starting to transport the carrier tape 24 from the storage cassette 22B, the information update unit 145 updates the information stored in the wireless tag 28 of the receiving cassette 22A via the reader / writer 29a. The timing at which the information update unit 145 is linked to the start of transport of the carrier tape 24, i.e., the timing at which the information is updated, may be any timing from the start of the switching operation of the next tape 24b to a predetermined time after the switching operation starts using a timer, or immediately before the leading component 5 reaches the component removal position 23ba.

[0225] In step ST35, the information update unit 145 erases the component information from the wireless tag 28 of the emptied storage cassette 22B.

[0226] In step ST36, the information updating section 145 further updates the cassette management information 111 stored in the storage section 105 of the management device 92. In this way, the information updating due to the tape change is completed.

[0227] Although the information updating unit 145 copies the component information read from the wireless tag 28 of the storage cassette 22B in association with the switching operation of the next tape 24b as the component information of the wireless tag 28 of the receiving cassette 22A, a different method may be used to update the component information of the wireless tag 28 of the receiving cassette 22A. Specifically, the component information (component ID) of the storage cassette 22B having the same component supply position number as the component supply position number of the receiving cassette 22A whose component information is to be updated in the cassette management information 111 may be read, and the read component information (component ID) may be copied to the wireless tag 28 of the receiving cassette 22A.

[0228] <<Parts replenishment work>> Next, the component replenishment work will be described with reference to Fig. 34. As components 5 continue to be mounted on the board 4, the number of components 5 decreases, and the component supply unit 3 will need to replenish the components 5. Therefore, the management device 92 identifies the components 5 that are predicted to run out and issues a replenishment instruction. Fig. 34 is a diagram showing the configuration related to the component replenishment work.

[0229] The component replenishment work support device 98 supports the component replenishment work of placing the storage cassette 22B containing the replenishment carrier tape 24 in the cassette mounting section 46a. The component replenishment work support device 98 is made up of a memory unit 105 or 142 that stores setup information regarding the arrangement of the components 5 in the cassette base 46, a component replenishment instruction unit 103, a replenishment cassette detection unit 171, and a replenishment cassette determination unit 172. Note that in the following description, the component replenishment work support device 98 is described as being part of the component mounting device 1, but it may also be configured as a device separate from the component mounting device 1.

[0230] The management device 92 references the production program 112 and the production record 113 to determine the remaining number of components required to produce the planned number of mounted boards. The management device 92 acquires the planned production number of mounted boards and the number of each component 5 to be mounted on one board 4 (number of components per board) from the production program 112. The production record 113 includes the number of boards 4 on which components have been mounted (production number). The management device 92 determines the remaining number of required components from the planned production number, the number of components per board, and the production number. The management device 92 compares the remaining number of required components with the remaining number of components in the rolls 25 stored in the receiving cassette 22A and the storage cassette 22B by referring to the cassette management information 111. If the management device 92 determines that components need to be replenished, the component replenishment instruction unit 103 identifies the components that can be replenished from the production record 113, the production program 112 (planned production number), the remaining number of components, and the status of the component supply unit 23. When the component replenishment instruction unit 103 identifies a component that can be replenished, it notifies the worker by transmitting information indicating the content of the component replenishment work to the portable information terminal 95 carried by the worker. Note that when an automatic replenishment means such as a transport robot is to replace the storage cassette 22B or remove the carrier tape 24 from the roll 25 stored in the storage cassette 22B and insert it into the component supply unit 23 instead of the worker, the component replenishment instruction unit 103 instructs the automatic replenishment means to perform the component replenishment work.

[0231] The supply unit state detection section 146 of the main body control section 17 detects a component supply unit 23 that is in a state capable of holding the next tape 24b. Such a component supply unit 23 is in the state shown in Fig. 16(b) or a component supply unit 23 with no carrier tape 24 attached at all.

[0232] The component replenishment support unit 147 includes a replenishment cassette detection unit 171 , a replenishment cassette determination unit 172 , and a replenishment permission unit 173 .

[0233] The replenishment cassette detection unit 171 detects the attachment of the storage cassette 22B to the storage cassette attachment unit 39. Like the cassette detection unit 161, the replenishment cassette detection unit 171 also detects the attachment of the storage cassette 22B to the storage cassette attachment unit 39 by utilizing the wireless tag detection function of the reader / writers 29a and 29b. Furthermore, the replenishment cassette detection unit 171 identifies the position (attachment location) of the attached storage cassette 22B based on the cassette detection signal received from the reader / writer 29b. The cassette detection unit 161 refers to the connection information 152 to identify the component supply position number corresponding to the connection port from which the cassette detection signal was sent, as information indicating the attachment location of the storage cassette 22B.

[0234] The replenishment cassette determination unit 172 determines whether the storage cassette 22B loaded into the storage cassette loading unit 39 by the worker contains the correct carrier tape 24. For example, the replenishment cassette determination unit 172 determines whether the loaded storage cassette 22B is correct by comparing the loaded position of the storage cassette 22B, component information acquired from the wireless tag 28 of the loaded storage cassette 22B, and setup information defined in the production program 112. Note that as another determination method by the replenishment cassette determination unit 172, the component information stored in the wireless tag 28 of the storage cassette 22B and the component information stored in the wireless tag 28 of the receiving cassette 22A may be read and compared to determine whether the appropriate storage cassette 22B has been loaded.

[0235] When the replenishment cassette determination unit 172 determines that the appropriate storage cassette 22B has been installed, the replenishment permission unit 173 sends a permission signal to the unit control unit 64 of the component supply unit 23 in which the carrier tape 24 of the storage cassette 22B should be set, instructing it to accept the carrier tape 24.

[0236] Next, the flow of the component replenishment work will be described with reference to Fig. 35. Fig. 35 is a flowchart showing the processing (component replenishment work) of the component replenishment support unit 147 during the component replenishment work. The flowchart in Fig. 35 assumes that the component replenishment work is performed by a worker. The flowchart also assumes that the determination of the storage cassette 22B by the replenishment cassette determination unit 172 is made, in principle, by comparing the component information stored in the wireless tag 28 of the storage cassette 22B with the component information stored in the wireless tag 28 of the receiving cassette 22A.

[0237] When the component replenishment instruction unit 103 of the management device 92 identifies a component that can be replenished, it transmits information indicating the component replenishment work content to the portable information terminal 95 carried by the worker. The worker checks the component replenishment work content displayed on the portable information terminal 95 and replaces the empty storage cassette 22B mounted in the storage cassette mounting unit 39 of the specified component supply unit 3 with the storage cassette 22B that stores the component to be replenished. As a result of this replacement, in step ST41, the replenishment cassette detection unit 171 detects that a new storage cassette 22B has been mounted in the storage cassette mounting unit 39. If the replenishment cassette detection unit 171 has not yet detected that a new storage cassette 22B has been mounted in the storage cassette mounting unit 39 (No in step ST41), it waits until the replacement is complete.

[0238] When the replenishment cassette detection unit 171 detects that the storage cassette 22B is attached (Yes in step ST41), in step ST42, it identifies the attachment location of the storage cassette 22B. By referring to the connection information 152, the replenishment cassette detection unit 171 identifies the component supply position number corresponding to the connection port from which the cassette detection signal is sent as information indicating the attachment location of the attached tape cassette 22.

[0239] In step ST43, the replenishment cassette determination unit 172 reads the component information of the storage cassette 22B via the reader / writer 29b.

[0240] In step ST44, the refill cassette determination unit 172 reads the component information of the receiving cassette 22A via the reader / writer 29a.

[0241] In step ST45, the refill cassette determination unit 172 determines whether or not there is component information for the receiving cassette 22A. If there is no component information for the receiving cassette 22A (Yes in step ST45), it cannot be determined by comparing the component information stored in the wireless tag 28 of the storage cassette 22B with the component information stored in the wireless tag 28 of the receiving cassette 22A. In this case, the setup information of the production program 112 is referenced in step ST51.

[0242] If the replenishment cassette determination unit 172 determines in step ST45 that component information for the receiving cassette 22A is available (NO in step ST45), or if the replenishment cassette determination unit 172 references the setup information in step ST51, the replenishment cassette determination unit 172 determines in step ST46 whether the component information for the receiving cassette 22A matches the component information for the storage cassette 22B. If the setup information is referenced in step ST51, the replenishment cassette determination unit 172 determines whether the correspondence between the mounting location (component supply position number) of the mounted storage cassette 22B and the read component information matches the contents of the setup information in the production program 112.

[0243] If there is a match (Yes in step ST46), in step ST47, the component replenishment support unit 147 notifies the worker by turning on the lamp 23f of the component supply unit 23 that is to be replenished with the component 5. In this way, the component replenishment support unit 147 and the lamp 23f constitute a replenishment target notification unit that notifies the worker of the component supply unit 23 to which the carrier tape 24 of the storage cassette 22B should be set.

[0244] In step ST48, the replenishment permission section 173 transmits a permission signal to the unit control section 64 of the component supply unit 23 to allow the carrier tape 24 to be carried in.

[0245] In step ST49, component replenishment support unit 147 determines whether the worker has completed the component replenishment work. If component replenishment support unit 147 cannot confirm that the work is complete (No in step ST49), it waits for an instruction from the worker that the work is complete. If the worker presses switch 23g and component replenishment support unit 147 can confirm that the work is complete (Yes in step ST49), component replenishment instruction unit 103 determines in step ST50 whether or not there is component replenishment work for other parts.

[0246] If there is a need to replenish another part 5 (Yes in step ST50), the process is repeated from step ST41. If there is no need to replenish another part 5 (No in step ST50), the part replenishment work is terminated.

[0247] If there is a mismatch in step ST46 (No in step ST46), a message instructing the user to check the installation location of the storage cassette 22B is displayed on the portable information terminal 95 in step ST52.

[0248] In step ST53, if the replenishment cassette detection unit 171 detects the cassette removal (Yes in step ST53), it performs the process of step ST50. If the replenishment cassette detection unit 171 cannot detect the cassette removal (No in step ST53), it performs the process of step ST52 again.

[0249] The flowchart of the processing (component replenishment work) of the component replenishment support unit 147 shown in FIG. 35 is based on the assumption that the determination of the storage cassette 22B by the replenishment cassette determination unit 172 is made by comparing the component information stored in the wireless tag 28 of the storage cassette 22B with the component information stored in the wireless tag 28 of the receiving cassette 22A. However, if the processing of step ST46 is unified into a method of comparing with the setup information of the production program 112, the flowchart is modified as follows. In the modified flowchart, the processing of steps ST44 and ST45 is deleted, and processing is modified so that processing is performed in the order of step ST51 and step ST46 following step ST43. The processing content of steps ST51 and ST46 is the same as that described above. In this way, it is also possible to unify the determination of the storage cassette 22B by the replenishment cassette determination unit 172 into a method of comparing with the information of the production program 112.

[0250] The setup support device 97 of this embodiment is a setup support device that supports the setup work of installing a plurality of tape cassettes 22 storing carrier tapes 24 to be used in the component mounting device 1 in a plurality of cassette attachment sections 46a of the component mounting device 1. The component mounting device 1 includes a plurality of component supply units 23 that transport the carrier tapes 24 packed with components 5 and supply the components 5 to the component removal positions 23ba, and a mounting head 13 that picks up the components 5 from the component removal positions 23ba and mounts them on the board 4, and performs the component mounting work of picking up the components 5 with the mounting head 13 and mounting them on the board 4. The setup support device 97 includes a plurality of wireless communication units 29 arranged in one-to-one correspondence with the cassette mounting units 46a and communicating with the wireless tag 28 of the tape cassette 22 mounted in one of the cassette mounting units 46a; a memory unit 105 that stores setup information specifying the components to be placed in the cassette mounting unit 46a; a cassette detection unit 161 that detects that a tape cassette 22 has been mounted in the cassette mounting unit 46a; and a cassette determination unit 162 that, when the cassette detection unit 161 detects that the tape cassette 22 has been mounted, identifies the cassette mounting unit 46a in which the tape cassette 22 has been mounted, and reads the component information stored in the wireless tag 28 via the wireless communication units 29, refers to the setup information, and determines whether a tape cassette 22 containing an appropriate carrier tape 24 has been mounted.

[0251] The cassette determination unit 162 determines whether the tape cassette 22 containing the appropriate carrier tape 24 has been loaded by referencing the information on the wireless tag 28 of the loaded tape cassette 22 and the setup information, so even if an operator or a transport robot makes a mistake in setting up the carrier tape 24, the mistake can be noticed. This makes it possible to prevent incorrect components from being erroneously supplied to the component supply unit 23.

[0252] The setup support device 97 also includes a unit notification unit 163 that, when the cassette determination unit 162 determines that a tape cassette 22 containing an appropriate carrier tape 24 has been loaded, notifies the operator of the component supply unit 23 into which the carrier tape 24 of the tape cassette 22 should be set. This allows the operator to know that the correct tape cassette 22 has been loaded, and also prevents the operator from making a mistake about which component supply unit 23 the carrier tape 24 should be inserted into.

[0253] Furthermore, the setup support device 97 further includes a permission unit 164 that, when the cassette determination unit 162 determines that a tape cassette 22 containing an appropriate carrier tape 24 has been loaded, transmits permission to receive the carrier tape 24 to the component supply unit 23 that transports the carrier tape 24 of the tape cassette 22. As a result, the component supply unit 23 does not permit reception of the carrier tape 24 unless the cassette determination unit 162 determines that the carrier tape 24 is appropriate and receives permission to receive it from the permission unit 164, thereby preventing an inappropriate carrier tape 24 from being carried into the component supply unit 23.

[0254] Furthermore, when the wireless communication unit 29 changes from a state in which it has not detected the wireless tag 28 to a state in which it has detected the wireless tag 28, the cassette detection unit 161 detects that the tape cassette 22 has been installed in the cassette mounting unit 46a corresponding to the wireless communication unit 29. This makes it possible to easily detect that the tape cassette 22 has been installed in the cassette mounting unit 46a without providing any other detection sensor.

[0255] Furthermore, in the setup support device 97 of this embodiment, the component mounting device 1 is a receiving cassette 22A and a storage cassette 22B, which are tape cassettes 22 having a space 41a for storing a roll 25 of carrier tape 24 on which components 5 are packed, and an opening 41b through which at least the roll 25 can be taken in and out of the space 41a, and which are provided with a wireless tag 28. The receiving cassette 22A transports the carrier tape 24 from the receiving cassette 22A to supply the components 5 to the component pick-up position 23ba, and the storage cassette 22B transports the carrier tape 24 from the receiving cassette 22A to supply the components 5 to the component pick-up position 23ba, and the carrier tape 24 is transported from the storage cassette 22B following the carrier tape 24. a component supply unit (23) that supplies components (5) to the component take-out position (23ba); a mounting head (13) that picks up the components (5) from the component take-out position (23ba) and mounts them on the board (4); a plurality of cassette mounting sections (46a) that mount the receiving cassette (22A) and the storage cassette (22B) in series along the conveying direction (Y direction) of the carrier tape (24) by the component supply unit (23) with their openings (41b) facing each other, with the storage cassette (22B) positioned upstream in the conveying direction; and a plurality of cassette mounting sections (46a) that are arranged in one-to-one correspondence with the cassette mounting sections (46a) and are mounted on one cassette mounting section (46a). The setup support device 97 is provided with a wireless communication unit 29 that communicates with the wireless tags 28 of the loaded receiving cassette 22A and the loaded storage cassette 22B, and supports a setup operation of placing the storage cassette 22B, which stores the carrier tape 24 to be used in the component loading device 1, in the cassette loading section 46a. The setup support device 97 supports the setup operation of placing the storage cassette 22B, which stores the carrier tape 24 to be used in the component loading device 1, in the cassette loading section 46a, and performs setup operations by specifying the components 5 to be placed in the multiple cassette loading sections 46a. The device is provided with a memory unit 105 that stores information, a cassette detection unit 161 that detects that the storage cassette 22B has been mounted in the cassette mounting unit 46a, and a cassette determination unit 162 that, when the cassette detection unit 161 detects that the storage cassette 22B has been mounted, identifies the cassette mounting unit 46a in which the storage cassette 22B has been mounted, reads the component information stored in the wireless tag 28 of the storage cassette 22B via the wireless communication unit 29, refers to the setup information, and determines whether a cassette containing an appropriate carrier tape 24 has been mounted.

[0256] Furthermore, the cassette determination unit 162 determines whether a cassette containing an appropriate carrier tape 24 has been loaded by referencing the information on the wireless tag 28 of the loaded storage cassette 22B and the setup information, so even if an operator or a transport robot makes a mistake in setting up the carrier tape 24, this mistake can be noticed. Therefore, even if the carrier tape 24 of the storage cassette 22B is being transported while the receiving cassette 22A is empty in the receiving cassette 22A and the storage cassette 22B arranged in series along the transport direction of the carrier tape 24, it is possible to prevent a different component from being erroneously supplied to the component supply unit 23.

[0257] The component supply unit 23 further includes an information update unit 165 that, when it detects the transport of the carrier tape 24 in the storage cassette 22B, updates the information stored in the wireless tag 28 of the receiving cassette 22A via the wireless communication unit 29. The information update unit 165 updates the information stored in the wireless tag 28 of the receiving cassette 22A via the wireless communication unit 29, so that the information in the wireless tag 28 of the receiving cassette 22A can correspond to the carrier tape 24 that has been transferred, and traceability of the roll body 25 can be ensured.

[0258] Furthermore, the information update unit 165 writes component information about the components 5 packed in the carrier tape 24 of the storage cassette 22B to the wireless tag 28 of the receiving cassette 22A. This allows the component information stored in the wireless tag 28 of the receiving cassette 22A to be updated to the component information of the roll 25 that has been moved from the storage cassette 22B into the receiving cassette 22A.

[0259] The information update unit 165 reads information from the wireless tag 28 of the storage cassette 22B via the wireless communication unit 29 and copies the information to the wireless tag 28 of the receiving cassette 22A. This also ensures the traceability of the roll 25 that has been moved from the storage cassette 22B into the receiving cassette 22A.

[0260] In addition, the setup support method of this embodiment supports the setup work of installing a plurality of tape cassettes 22 containing carrier tapes 24 to be used by the component mounting device 1 in a plurality of cassette mounting sections 46a of the component mounting device 1, the component mounting device 1 comprising a plurality of component supply units 23 that transport carrier tapes 24 packed with components 5 and supply the components 5 to the component removal position 23ba, and a mounting head 13 that picks up the components 5 from the component removal position 23ba and mounts them on the board 4, and which performs the component mounting work of picking up the components 5 with the mounting head 13 and mounting them on the board 4. This setup support method includes a cassette detection step in which the cassette detection unit 161 detects that a tape cassette 22 has been installed in a cassette mounting unit 46a, and a cassette determination step in which, when the cassette detection unit 161 detects that the tape cassette 22 has been installed, the cassette determination unit 162 identifies the cassette mounting unit 46a in which the tape cassette 22 has been installed, reads the component information stored in the wireless tag 28 via the wireless communication unit 29, which is arranged in one-to-one correspondence with the cassette mounting unit 46a and communicates with the wireless tag 28 of the tape cassette 22 installed in one cassette mounting unit 46a, and refers to setup information stored in the memory unit 105 that specifies the component 5 to be placed in the cassette mounting unit 46a, and determines whether a tape cassette 22 containing an appropriate carrier tape 24 has been installed.

[0261] In the cassette determination step, the cassette determination unit 162 determines whether the tape cassette 22 containing the appropriate carrier tape 24 has been loaded by referencing the information on the wireless tag 28 of the loaded tape cassette 22 and the setup information, so even if an operator or a transport robot makes a mistake in setting up the carrier tape 24, this mistake can be noticed. Therefore, it is possible to prevent incorrect components from being erroneously supplied to the component supply unit 23.

[0262] Furthermore, the setup support method of the present embodiment is a method in which component mounting device 1 includes receiving cassette 22A and storage cassette 22B, each of which is a tape cassette 22 having space 41a for storing roll 25 of carrier tape 24 on which components 5 are packed, and an opening 41b through which at least roll 25 can be taken in and out of space 41a, and which is provided with wireless tag 28; component supply unit 23 which transports carrier tape 24 from receiving cassette 22A to supply components 5 to component take-out position 23ba, and transports carrier tape 24 from storage cassette 22B following carrier tape 24 to supply components 5 to component take-out position 23ba; 4, a plurality of cassette mounting sections 46a for mounting the receiving cassette 22A and the storage cassette 22B in series along the conveying direction (Y direction) of the carrier tape 24 by the component supply unit 23 with their openings 41b facing each other, and with the storage cassette 22B positioned upstream in the conveying direction, and a wireless communication section 29 arranged in one-to-one correspondence with the cassette mounting sections 46a and communicating with the wireless tags 28 of the receiving cassette 22A and the storage cassette 22B mounted on one cassette mounting section 46a, thereby supporting the setup work of placing the storage cassette 22B, which contains the carrier tape 24 to be used in the component mounting device 1, in the cassette mounting section 46a. This setup support method includes a cassette detection step in which the cassette detection unit 161 detects that the storage cassette 22B has been mounted in the cassette mounting unit 46a, and a cassette determination step in which, upon detecting the mounting of the storage cassette 22B in the cassette detection step, the cassette determination unit 162 identifies the cassette mounting unit 46a in which the storage cassette 22B has been mounted, reads the component information stored in the wireless tag 28 of the storage cassette 22B via the wireless communication unit 29, and determines whether or not a tape cassette containing an appropriate carrier tape 24 has been mounted by referring to setup information that specifies the components to be placed in the multiple cassette mounting units 46a stored in the memory unit 105.

[0263] In the cassette determination step, the cassette determination unit 162 determines whether or not a tape cassette containing an appropriate carrier tape 24 has been loaded by referencing the information on the wireless tag 28 of the loaded storage cassette 22B and the setup information, so even if an operator or a transport robot makes a mistake in setting up the carrier tape 24, the mistake can be noticed. Therefore, it is possible to prevent incorrect components from being erroneously supplied to the component supply unit 23.

[0264] Although the present disclosure has been fully described in connection with the preferred embodiments with reference to the accompanying drawings, various variations and modifications will be apparent to those skilled in the art. Such variations and modifications should be understood to be included within the scope of the present disclosure as defined by the appended claims, unless they depart therefrom. Furthermore, changes in the combination and order of elements in each embodiment may be made without departing from the scope and spirit of the present disclosure.

[0265] Although the component mounting system 91 in the above-described embodiment is equipped with the setup station 94, this is not limiting, and the component mounting system 91 may be configured not to include the setup station 94. If the component mounting system 91 does not include the setup station 94, the setup work may be performed with the component mounting device 1 line stopped and the component supply unit 3 connected to the main body 2 of the component mounting device 1.
