Description

Technical Field

[0001] The present disclosure relates to a component supply device that supplies components to a component mounting device.

Background Art

[0002] Conventionally, a tape feeder is known that can continuously supply a subsequent carrier tape (subsequent tape) to a component extraction position after a preceding carrier tape (preceding tape) containing components.

[0003] For example, the tape feeder described in Patent Document 1 includes a tape holding unit that holds a subsequent tape whose tip is inserted into a tape insertion port on the upstream side of a tape conveyance path. The tape holding unit has a tape holding portion that can be displaced in the vertical direction by an operator's operation, and is configured such that the subsequent tape held by displacing the tape holding portion in the vertical direction can be dropped downward.

[0004] In this tape feeder, when the preceding tape is discharged, the subsequent tape becomes the preceding tape, and component supply is started, the operator operates the tape holding unit to drop the preceding tape from the tape holding unit to correct the position of the preceding tape. As a result, the subsequent tape can be replenished. Thereafter, a new subsequent tape is held by the tape holding unit, and its tip is inserted into the tape insertion port to complete the replenishment operation of the carrier tape.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the conventional tape feeder, since the operator manually performs the operation of discharging the leading tape downward, there is a risk that the operator may forget the tape discharging operation. In this case, when all the parts on the leading tape are mounted, the parts cannot be replenished to the component mounting device, and the mounting operation of the component mounting device must be stopped, which may result in a decrease in productivity. In addition, since the switching from the leading tape to the subsequent tape is manually performed by the operator, it is difficult to automate or reduce the manning of the component supply to the component mounting device.

[0007] Therefore, an object of the present disclosure is to solve the above-described conventional problems, and to provide a component supply device capable of improving productivity and automating or reducing the manning of the component supply to the component mounting device.

Means for Solving the Problems

[0008] The component supply device of the present disclosure has, on the upstream side, a first conveyance path into which a carrier tape is inserted and a second conveyance path located below the first conveyance path, respectively. The first conveyance path and the second conveyance path merge to form a tape conveyance path that guides the running of the carrier tape in the downstream direction, a first tape conveyance unit that sequentially conveys the carrier tape on the tape conveyance path at a position downstream of the position where the first conveyance path and the second conveyance path merge to a component take-out position on the tape conveyance path, a tape holding unit that holds the carrier tape in at least a part of the first conveyance path, a second tape conveyance unit that conveys the carrier tape held by the tape holding unit in the downstream direction of the tape conveyance path, and a tape holding release mechanism that drops the carrier tape held by the tape holding unit from the first conveyance path to the second conveyance path. The tape holding release mechanism operates using the power of the drive source of the second tape conveyance unit.

Effects of the Invention

[0009] According to the present disclosure, it is possible to provide a component supply device capable of improving productivity and automating or reducing the manning of the component supply to the component mounting device.

[0021] 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 the same technical idea are included in the present disclosure.

[0022] (Embodiment) The configuration of the component mounting device 1 according to the embodiments of the present disclosure will be described with reference to FIG. 1. In FIG. 1, as two axial directions orthogonal to each other in the horizontal plane, the X direction (the direction perpendicular to the paper surface in FIG. 1) in the substrate conveyance direction and the Y direction (the left - right direction in FIG. 1) orthogonal to the substrate conveyance direction are shown. Further, the Z direction (the up - down direction in FIG. 1) is shown as the height direction orthogonal to the horizontal plane.

[0023] With reference to FIG. 1, the configuration of the component mounting device 1 will be described. The component mounting device 1 manufactures a mounted substrate on which components are mounted on a substrate. The substrate conveyance mechanism 2 provided on the upper surface of the base 1a conveys, positions, and holds the substrate 3 in the X direction. Above the substrate conveyance mechanism 2, a mounting head 4 that moves in the horizontal directions (X direction, Y direction) by a head movement mechanism (not shown) is installed. On the upper part of a carriage 5 coupled to the base 1a on the side of the substrate conveyance mechanism 2, a plurality of tape feeders 6 are arranged side by side in the X direction.

[0024] On the front side of the carriage 5 and below the tape feeder 6, a reel holding portion 9 that rotatably supports a reel 8 around which a carrier tape 7 storing the components supplied to the component mounting device 1 is wound is installed. The tape feeder 6 conveys the carrier tape 7 stored in the reel 8 in the tape feed direction and supplies the components to the component pickup position P1 by the mounting head 4. An identifier 8a for identifying the components accommodated in the carrier tape 7 is attached to the reel 8. The identifier 8a is, for example, a two - dimensional barcode or an RFID tag.

[0025] The component mounting device 1 includes a substrate transfer mechanism 2, a mounting head 4, and a mounting control unit 10 that controls the head movement mechanism. The mounting control unit 10 transmits a component supply command to the tape feeder 6, controls the mounting head 4 and the head movement mechanism, and causes the mounting head 4 to take out the components supplied by the tape feeder 6 at the component take-out position and transfer and mount them at the mounting points of the substrate 3 held by the substrate transfer mechanism 2. In this way, the tape feeder 6 is a component supply device that supplies the components stored in the carrier tape 7 to the component mounting device 1. The components stored in the carrier tape 7 are, for example, chip-type electronic components. Above the trolley 5, an openable and closable main body cover 11 is installed to cover the movable mechanisms such as the mounting head 4 while the operator is working so that the operator does not touch them.

[0026] The component mounting device 1 further includes a reader device 15 that reads the information of the identifier 8a. The reader device 15 is, for example, a two-dimensional barcode reader or an RFID reader. The information of the identifier 8a read by the reader device 15 is sent to the mounting control unit 10. The mounting control unit 10 includes a collation unit 10a and a storage unit 10b. The mounting control unit 10 is composed of, for example, an arithmetic device such as a processor or an FPGA and a memory or an SSD.

[0027] The storage unit 10b stores the information of the components to be replenished to the tape feeder 6. The collation unit 10a collates the information of the identifier 8a read by the reader device 15 with the information of the components to be replenished stored in the storage unit 10b. When the collation unit 10a determines that the information of the identifier 8a and the information of the components to be replenished match, it transmits a signal indicating a match as a collation result to the feeder control unit 28. Also, when the collation unit 10a determines that the information of the identifier 8a and the information of the components to be replenished do not match, it transmits a signal indicating a mismatch as a collation result to the feeder control unit 28.

[0028] In FIG. 1, a collection box 12 for collecting an empty carrier tape 7 from which components are removed by the mounting head 4 and discharged from the rear of the tape feeder 6 is installed below the carriage 5. A discharge chute 13 for guiding the empty carrier tape 7 discharged from the tape feeder 6 to the collection box 12 is installed on the rear side of the carriage 5. A cutting portion 14 for cutting the empty carrier tape 7 at a predetermined length is installed in the discharge chute 13. The empty carrier tape 7 discharged from the tape feeder 6 is cut by the cutting portion 14 and collected in the collection box 12.

[0029] 《Tape Feeder》 Next, the configuration of the tape feeder 6 will be described with reference to FIGS. 2 and 3. FIG. 2 is a schematic diagram of the tape feeder 6 according to the embodiment. FIG. 3 is a partially enlarged view of the tape feeder 6.

[0030] The tape feeder 6 includes a tape conveyance path 20, a first tape conveyance unit 21, a second tape conveyance unit 23, a tape holding unit 26, and a tape holding release mechanism 34. The tape feeder 6 also includes an insertion port 20a for inserting the carrier tape 7 into the tape conveyance path 20 and a discharge port 20b from which the carrier tape 7 is discharged from the tape conveyance path 20.

[0031] The tape conveyance path 20 guides the carrier tape 7 pulled out from the reel 8 and inserted into the tape feeder 6 through the insertion port 20a to the component removal position P1 inside the tape feeder 6 and further guides it to the discharge port 20b.

[0032] The insertion port 20a opens on the upstream side (the left side in FIG. 2) in the tape feeding direction in the tape feeder 6. The discharge port 20b opens on the downstream side (the right side in FIG. 2) in the tape feeding direction. The tape conveyance path 20 communicates from the insertion port 20a to the discharge port 20b. At the component removal position P1 provided in the middle of the tape conveyance path 20, the mounting head 4 removes the components.

[0033] In the process of continuously executing the component mounting operation, a plurality of carrier tapes 7 stored in one reel 8 are sequentially inserted from the insertion port 20a as a unit lot and supplied to the tape feeder 6. Hereinafter, as necessary, among the two carrier tapes 7 introduced from the insertion port 20a and sent through the tape conveyance path 20, the carrier tape 7 sent first is referred to as the first tape 7p, and the carrier tape 7 sent after the first tape 7p is referred to as the second tape 7s for explanation (see FIG. 3). The tape conveyance path 20 has a first conveyance path 20c into which the carrier tape 7 is inserted on the upstream side, a second conveyance path 20d located below the first conveyance path 20c, and a third conveyance path 20e extending from the confluence position P2 of the second conveyance path 20d and the first conveyance path 20c to the discharge port 20b.

[0034] The first tape conveyance unit 21 conveys the carrier tape 7 to the component extraction position P1 on the downstream side in the tape conveyance path 20. The first tape conveyance unit 21 includes a first sprocket 21a engaged with the carrier tape 7 and a first motor 21b that rotationally drives the first sprocket 21a. Above the first tape conveyance unit 21, a tape cover 22 having a peeling blade for pressing the carrier tape 7 from above and exposing the components stored in the carrier tape 7 is attached. An opening is formed at a position corresponding to the component extraction position P1 of the tape cover 22. When the carrier tape 7 travels along the lower surface of the tape cover 22 by the first sprocket 21a, the components are exposed by the peeling blade, and the exposed components are conveyed to the opening formed downstream thereof, that is, the component extraction position P1. Note that the method of exposing the components stored in the carrier tape 7 may be a method (full peeling method) in which a pair of rollers (not shown) are arranged downstream of the component extraction position P1 of the tape conveyance path 20, and the top tape that seals the components in the carrier tape 7 is peeled off by these rollers. In the case of the full peeling method, it is not necessary to provide a peeling blade on the tape cover 22.

[0035] The second tape conveyance unit 23 sends the carrier tape 7 inserted into the first conveyance path 20c from the insertion port 20a to the first tape conveyance unit 21. The second tape conveyance unit 23 is disposed on the upstream side in the tape conveyance path 20. The second tape conveyance unit 23 includes, for example, a second motor 23a, a first gear 23b, a second gear 23c, a third gear 23d, a fourth gear 23e, a fifth gear 23f, and a second sprocket 23g.

[0036] The output gear 23aa of the second motor 23a engages with the first gear 23b. The second gear 23c is rotatably disposed coaxially with the first gear 23b and engages with the third gear 23d. The third gear 23d engages with the fourth gear 23e, and the fourth gear 23e engages with the fifth gear 23f. The fifth gear 23f is rotatably fixed to the second sprocket 23g that engages with the carrier tape 7. Therefore, the rotational driving force of the second motor 23a is transmitted from the first gear 23b to the second sprocket 23g via the fifth gear 23f.

[0037] The tape conveyance path 20 has a first conveyance path 20c and a second conveyance path 20d on the upstream side. The first conveyance path 20c and the second conveyance path 20d merge at the position P2. The carrier tape 7 supplied to the tape feeder 6 is first conveyed to the downstream side of the tape conveyance path 20 by the second tape conveyance unit 23 along the first conveyance path 20c. Eventually, when the carrier tape 7 is conveyed to the first tape conveyance unit 21, the carrier tape 7 is moved from the first conveyance path 20c to the second conveyance path 20d as the preceding first tape 7p. As a result, since the first tape 7p is conveyed downstream of the tape conveyance path 20 through the second conveyance path 20d and the third conveyance path 20e, the next second tape 7s can be inserted into the first conveyance path 20c.

[0038] The tape feeder 6 includes a tape stopper unit 24, a shutter unit 27, and a lock unit 45, which are respectively disposed below the second tape conveyance unit 23. The tape feeder 6 also includes a first sensor Sa1, a second sensor Sa2, and a third sensor Sa3.

[0039] The first sensor Sa1 detects that the carrier tape 7 inserted into the tape feeder 6 has reached a predetermined position on the third conveyance path 20e downstream of the position P2 where the second conveyance path 20d and the first conveyance path 20c merge.

[0040] The second sensor Sa2 detects that the carrier tape 7 traveling on the tape conveyance path 20 has reached upstream of the component take-out position P1. Therefore, the second sensor Sa2 is disposed downstream of the first sensor Sa1 on the tape conveyance path 20 and upstream of the third sensor Sa3 on the tape conveyance path 20.

[0041] The third sensor Sa3 detects that the carrier tape 7 traveling on the tape conveyance path 20 has reached the component take-out position P1. The third sensor Sa3 is disposed, for example, downstream of the second sensor Sa2 and the first sprocket 21a of the first tape conveyance unit. The first sensor Sa1 to the third sensor Sa3 are each an optical sensor that detects the presence or absence of the carrier tape 7, and are, for example, a color sensor or a photosensor.

[0042] The tape holding unit 26 supports the carrier tape 7 and maintains the posture in which the carrier tape 7 is conveyed in at least a part of the first conveyance path 20c. Refer to FIG. 4. The tape holding unit 26 includes a first support portion 30, a second support portion 31, a plate-like member 32, and a movable member 33. Hereinafter, for convenience, as shown in FIG. 4, one side is set to the left and the other side is set to the right in the downstream direction in which the carrier tape 7 is conveyed in the tape feeder 6.

[0043] The first support portion 30 supports one side portion in the width direction of the carrier tape 7 from below. The first support portion 30 is formed on the right side surface of the plate-like member 32. The second support portion 31 supports the other side portion of the carrier tape 7 from below.

[0044] The plate-like member 32 extends in the tape feeding direction and the vertical direction (Z direction). The inner surface (right side surface) of the plate-like member 32 is a guide surface for guiding the left side surface of the carrier tape 7. The plate-like member 32 is fixed to the side wall of the tape feeder 6.

[0045] The movable member 33 has a plate-like shape and is swingably connected in the vertical direction about the rotation axis 26a. The inner surface of the movable member 33 is a guide surface for guiding the right side surface of the carrier tape 7.

[0046] At the upper part of the movable member 33, a handle 38 having a lever for an operator to operate with a finger is formed. By the operator lifting the handle 38 upward, the upstream side of the movable member 33 can be lifted upward (see FIG. 9). In this way, the movable member 33 is displaceable in the vertical direction with respect to the fixed plate-like member 32 (see FIG. 11).

[0047] In FIG. 4, a rotation axis 39 having a rotation center parallel to the width direction of the carrier tape 7 is attached to the movable member 33. A second sprocket 23g is rotatably attached to the rotation axis 39 via a one-way clutch 40. A plurality of pins 41a are provided at a position on the left side of the outer peripheral surface of the second sprocket 23g (that is, the side close to the plate-like member 32). The pins 41a of the second sprocket 23g engage with the feed holes 7h formed in the carrier tape 7 whose lower surface is supported by the first support portion 30 and the second support portion 31 in a state where the movable member 33 is in the initial position.

[0048] The first support portion 30 supports the side portion on the side where the feed holes 7h of the carrier tape 7 are formed from below. The second sprocket 23g attached to the horizontal rotation axis 39 via the one-way clutch 40 constitutes a locking portion that engages with the feed holes 7h of the carrier tape 7 and locks the carrier tape 7 to the first support portion 30.

[0049] The one-way clutch 40 allows the rotation of the second sprocket 23g when the carrier tape 7 engaged with the second sprocket 23g moves on the tape holding portion 26 in the direction of the insertion port 20a, but does not allow the rotation in the reverse direction. Thereby, it is possible to prevent the carrier tape 7 from dropping off from the tape feeder 6. In this way, the second sprocket 23g mounted on the rotary shaft 39 having the horizontal direction as the rotation axis via the one-way clutch 40 is attached to the movable member 33.

[0050] A protrusion 42 protruding inward from the plate-like member 32 is formed at a position above the first support portion 30 on the inner surface of the plate-like member 32. A taper 42a having an inclined surface (an inclined surface that moves away from the right side surface of the plate-like member 32 upward) approaching the inner surface of the plate-like member 32 downward is formed at the lower end portion of the protrusion 42. That is, the width of the lower end portion of the protrusion 42 in the horizontal direction becomes narrower as it goes downward.

[0051] In FIG. 5, the position of the downstream end portion of the second support portion 31 is upstream of the position of the downstream end portion of the first support portion 30. Further, a notch portion 31a having an inclined surface whose side surface approaches the inner surface of the movable member 33 as it goes downstream is formed on the downstream side of the second support portion 31. That is, one end portion on the insertion port 20a side (downstream side) of the second support portion 31 has a width in the horizontal direction that becomes narrower as it goes toward the insertion port 20a side.

[0052] Next, with reference to FIGS. 6 to 10, the configuration of the tape holding release mechanism 34 will be described. FIGS. 6 to 10 are side views showing the configuration of the second tape conveyance portion 23 of the tape feeder 6 and the tape holding release mechanism 34.

[0053] The tape holding release mechanism 34 drops the carrier tape 7 held by the tape holding portion 26 in the first conveyance path 20c to the second conveyance path 20d. The tape holding release mechanism 34 operates using the power of the second motor 23a of the second tape conveyance portion 23. The tape holding release mechanism 34 includes a ratchet mechanism 35 that rotates by the driving force of the second motor 23a, and a lever 36 that swings by the ratchet mechanism 35.

[0054] The ratchet mechanism 35 is composed of a ratchet gear 35a and a ratchet pawl 35b. The ratchet gear 35a is rotatably attached to the third gear 23d coaxially with the third gear 23d. Therefore, the ratchet gear 35a rotates together with the third gear.

[0055] The lever 36 is, for example, L-shaped, with a ratchet pawl 35b formed at one end thereof and connected to the downstream end of the movable member 33 of the tape holding portion 26 at the other end. The lever 36 is provided with a rotation shaft 36a at its central portion, and the lever 36 is attached to the tape feeder 6 via the second motor 23a so as to be swingable around the rotation shaft 36a.

[0056] As shown in FIGS. 6 and 7, when the second motor 23a rotates forward, the second motor 23a and the ratchet gear 35a rotate counterclockwise. In this case, since the ratchet gear 35a acts to lift the ratchet pawl 35b of the lever 36, the ratchet pawl 35b continues to rotate idly without engaging with the ratchet gear 35a.

[0057] As shown in FIG. 8, when the second motor 23a rotates reversely, the second motor 23a and the ratchet gear 35a rotate clockwise. In this case, since the ratchet gear 35a acts to push down the ratchet pawl 35b of the lever 36, the ratchet pawl 35b engages with the ratchet gear 35a, and the lever 36 starts to rotate counterclockwise.

[0058] When the second motor 23a rotates further reversely, as shown in FIG. 9, since the ratchet gear 35a pushes down the ratchet pawl 35b of the lever 36, the lever 36 rotates counterclockwise. As a result, the lever 36 pushes down the downstream end of the movable member 33 of the tape holding portion 26 downward. As a result, the movable member 33 rotates clockwise around the rotation shaft 26a, and the second support portion 31 moves to the upper release position P3.

[0059] Furthermore, if the second motor 23a continues to rotate in the reverse direction, as shown in FIG. 10, the ratchet gear 35a continues to act so as to push down the ratchet pawl 35b of the lever 36. Therefore, the ratchet pawl 35b of the lever 36 does not engage with the ratchet gear 35a. Accordingly, the state in which the lever 36 pushes down the downstream end portion of the movable member 33 of the tape holding portion 26 downward is maintained, and the state in which the second support portion 31 of the tape holding portion 26 is located at the upper release position P3 continues.

[0060] Next, when the second motor 23a rotates forward, the ratchet gear 35a acts to lift the ratchet pawl 35b of the lever 36. Therefore, the ratchet gear 35a engages with the ratchet pawl 35b of the lever 36, and the lever rotates clockwise. As a result, the lever 36 lifts the downstream end portion of the movable member 33 of the tape holding portion 26 upward, and the second support portion 31 moves to the original position, which is the tape holding position.

[0061] Next, with reference to FIG. 11, the function of discharging the carrier tape 7 in the first conveyance path 20c from the tape holding portion 26 will be described. As shown in FIG. 11(a), with the movable member 33 located at the initial position and the second support portion 31 at the same height position as the first support portion 30, the carrier tape 7 is held by the tape holding portion 26. When discharging the carrier tape 7 in the first conveyance path 20c from the tape holding portion 26, the feeder control unit 28 rotates the second motor 23a of the second tape conveyance unit 23 in the reverse direction. As a result, the movable member 33 rises integrally with the second support portion 31 and the second sprocket 23g. Even if an operator manually holds and lifts the handle 38 upward, the movable member 33 rises.

[0062] As shown in Fig. 11(b), as the movable member 33 rises, the carrier tape 7 moves upward while the lower surface of the right side is supported by the second support portion 31, and the upper surface of the left side of the carrier tape 7 abuts against the protrusion 42. When the movable member 33 further rises, the pin 41a of the second sprocket 23g disengages from the feed hole 7h of the carrier tape 7. As shown in Fig. 11(c), when the carrier tape 7 further rises together with the movable member 33, the carrier tape 7 is pushed by the taper 42a of the protrusion 42 and is displaced counterclockwise while being displaced to a position (right side) where it does not overlap with the first support portion 30.

[0063] As shown in Fig. 11(d), when the movable member 33 further rises, the twist of the carrier tape 7 increases, and eventually the right end of the carrier tape 7 deviates and drops from the second support portion 31. At this time, the right end of the carrier tape 7 surely deviates and drops starting from the notch portion 31a on the downstream side of the second support portion 31. Also, since the left end of the carrier tape 7 is displaced to the right by the protrusion 42, the carrier tape 7 drops downward without being caught by the first support portion 30 (shown by a dotted line in the figure).

[0064] The carrier tape 7 released from the tape holding portion 26 moves as the first tape 7p to the second conveyance path 20d formed below the first conveyance path 20c (see Fig. 3). The detachment of the carrier tape 7 from the tape holding portion 26 is executed, for example, before the carrier tape 7 is inserted into the tape feeder 6 and the component is taken out from the component taking-out position P1. When the carrier tape 7 (the first tape 7p) detaches from the tape holding portion 26, the next carrier tape 7 (the second tape 7s) can be inserted into the tape holding portion 26 at any time.

[0065] 《Shutter Unit》 Next, with reference to Figs. 14 and 15, the shutter unit 27 will be described. Fig. 14 is a partially enlarged view around the shutter unit. Fig. 15 is a side view showing the configuration of the shutter unit 27 and the lock portion 45.

[0066] The shutter unit 27 prevents the carrier tape 7 from advancing until the collation of the components of the carrier tape 7 inserted into the first conveyance path 20c is completed. The shutter unit 27 includes a shutter 27a, a pin 27b, a coil spring 27c, and a fourth sensor Sa4.

[0067] The shutter 27a abuts against the carrier tape 7 to stop the advancement of the carrier tape 7. The shutter 27a includes a shutter body 27e and a plate-like member 27f.

[0068] The shutter body 27e includes an inclined portion 27ea against which the carrier tape 7 abuts, a long hole 27eb extending in the vertical direction, and a stepped portion 27ec that fits with the locking portion 45. The pin 27b is inserted into the long hole 27eb, and the shutter 27a is displaceable in the vertical direction along the long hole 27eb.

[0069] The plate-like member 27f extends upward from the shutter body 27e. The fourth sensor Sa4 detects whether the shutter 27a is located at the tape stop position P4 where the advancement of the carrier tape 7 is stopped or at the retracted position P5 above the tape stop position P4. The fourth sensor Sa4 is, for example, an optical sensor. When the shutter 27a is at the tape stop position P4, since the shutter 27a descends into the first conveyance path 20c, the fourth sensor Sa4 cannot detect the plate-like member 27f. Also, when the shutter 27a is at the retracted position P5, since the shutter 27a ascends upward from the first conveyance path 20c, the fourth sensor Sa4 detects the plate-like member 27f.

[0070] The coil spring 27c biases the shutter body 27e so as to push down the shutter 27a, that is, so that the lower end of the shutter body 27e contacts the first conveyance path 20c. When the carrier tape 7 is conveyed downstream by the second tape conveyance unit 23, the carrier tape 7 lifts the shutter 27a against the spring force of the coil spring 27c and advances.

[0071] The locking part 45 locks the displacement of the shutter 27a according to the control of the feeder control part 28. The locking part 45 includes a solenoid 46, a lever 47, and a coil spring 48.

[0072] The solenoid 46 attracts the lever 47, which prevents the displacement of the shutter 27a, to the downstream side in order to enable the shutter 27a to be displaced from the retracted position P5 to the tape stop position P4. The solenoid 46 includes a plunger 46a and a disk-shaped plate member 46b fixed to the tip of the plunger 46a. The plate member 46b of the solenoid 46 is engaged with the downstream end 47b of the lever 47. When the solenoid 46 receives an attraction instruction from the feeder control part 28, it displaces the plunger 46a to the attraction position and displaces the lever 47 to the downstream side. When the attraction instruction from the feeder control part 28 disappears, the solenoid 46 displaces the plunger 46a back to the original release position.

[0073] The lever 47 is biased upstream by the coil spring 48, that is, toward the shutter 27a side. The upstream end 47a of the lever 47 is fitted with the stepped portion 27ec of the shutter body 27e when the plunger 46a of the solenoid 46 is in the released state. Thereby, the shutter 27a is prevented from rising to the retracted position P5, and the movement of the shutter 27a is locked.

[0074] When the result of the component verification by the mounting control part 10 indicates that the component matches the component to be supplied, the feeder control part 28 sends an attraction instruction to the solenoid 46. As a result, as shown in FIG. 14, the solenoid 46 attracts the plunger 46a and displaces the lever 47 to the downstream side. As a result, the upstream end 47a of the lever 47 disengages from the stepped portion 27ec of the shutter body 27e, and the lock of the shutter 27a is released.

[0075] Even when the lock of the shutter 27a is released, the shutter 27a is biased downward by the coil spring 27c. However, after the feeder control unit 28 stops giving the instruction to attract the solenoid 46, it sends an instruction to convey the tape to the second tape conveyance unit 23, so that the carrier tape 7 is conveyed downstream. As a result, the tip of the carrier tape 7 pushes up the inclined portion of the shutter body 27e against the spring force of the coil spring 27c.

[0076] When the shutter body 27e is pushed upward by the tip of the carrier tape 7, the plate-like member 27f of the shutter 27a is also displaced upward, and the fourth sensor Sa4g detects the plate-like member 27f. As a result, it is possible to detect that the carrier tape 7 passes below the shutter 27a, that is, the carrier tape 7 is conveyed from the first conveyance path 20c toward the third conveyance path 20e.

[0077] In addition, when the feeder control unit 28 determines, as a result of the collation of parts by the mounting control unit 10, that the parts do not match the parts to be supplied, the feeder control unit 28 notifies the operator, for example, from the operation display panel 29 that the set reel 8 is incorrect. When the operator recognizes that the reel 8 is incorrect, the operator lifts the handle 38 of the tape holding unit 26 and removes the erroneously inserted carrier tape 7 from the first conveyance path 20c.

[0078] 《Tape stopper unit》 Next, with reference to FIGS. 16 to 18, the configuration of the tape stopper unit 24 will be described. The tape stopper unit 24 stops the second tape 7s inserted into the first conveyance path 20c from proceeding to the third conveyance path 20e when the first tape 7p is being conveyed through the second conveyance path 20d and the third conveyance path 20e.

[0079] The tape stopper unit 24 includes a stopper 24a, a lever 24b, and a fifth sensor Sa5.

[0080] The stopper 24a is, for example, a plate-like member and is displaceable between a stop position P6 (see FIG. 17) for stopping the advancement of the second tape 7s and a stopper release position P7 (see FIG. 18) for releasing the stop of the advancement of the second tape 7s. The stopper 24a includes a contact portion 24aa, a tip portion 24ab, and a fulcrum 24ac. The contact portion 24aa is such that when the stopper 24a abuts against the tip of the second tape 7s at the stop position P6 which is a predetermined position on the first conveyance path 20c, it prevents the second tape 7s from moving downstream along the first conveyance path 20c.

[0081] The tip portion 24ab is a downstream portion of the stopper 24a and is a transmitted portion that receives power for displacing the lever 24b from the stop position P6 to the stopper release position P7.

[0082] The fulcrum 24ac is a fulcrum that serves as a rotation center for the stopper 24a to be displaced by rotation to the stop position P6 and the stopper release position P7. The fulcrum 24ac is located above the first conveyance path 20c and upstream of the contact portion 24aa.

[0083] The lever 24b functions as a drive unit for moving the stopper 24a between the stop position P6 and the stopper release position P7. The lever 24b itself is a link and includes a tape pressing portion 24ba, a tip portion 24bb, a claw portion 24bc, and a fulcrum 24bd.

[0084] The tape pressing portion 24ba presses the first tape 7p conveyed on the third conveyance path 20e from above. The coil spring 24c is biased so that the tape pressing portion 24ba is pushed downward. The first tape 7p advances in the downstream direction and lifts the tape pressing portion 24ba against the spring force of the coil spring 24c.

[0085] When the first tape 7p lifts the tape pressing portion 24ba, the claw portion 24bc extending upward from the upper part of the lever 24b is detected by the fifth sensor Sa5. Also, in this state, the tip portion 24bb on the upstream side of the lever 24b is in a lowered state, and the tip portion 24bb supports the weight of the tip portion 24ab of the stopper 24a.

[0086] As shown in FIG. 18, when all of the first tape 7p is conveyed to the downstream side, the tape pressing portion 24ba rotates clockwise by the spring force of the coil spring 24c and contacts the third conveyance path 20e. As a result, the lever 24b rotates clockwise about the fulcrum 24bd, and the tip portion 24bb of the lever 24b rotates the tip portion 24ab of the stopper 24a counterclockwise. The tip portion 24bb functions as a power transmission portion that transmits the rotational power to the tip portion 24ab of the stopper 24a. As a result, the stopper 24a rotates and displaces from the stop position P6 to the stopper release position P7, and the contact portion 24aa is released from contacting the second tape 7s. At this time, the opening direction of the contact portion 24aa from the stop position P6 to the stopper release position P7 is the traveling direction of the second tape 7s. In other words, from the stop position P6 to the stopper release position P7, the contact portion 24aa rotates in a direction away from the tip of the second tape 7s, so that it is possible to prevent the contact portion 24aa from biting into the tip of the second tape 7s, and it is possible to prevent the second tape 7s from being jammed when the stopper 24a is released.

[0087] Also, due to the rotation of the lever 24b, the detection signal from the fifth sensor Sa5 is no longer transmitted to the feeder control unit 28. When the feeder control unit 28 stops receiving the detection signal from the fifth sensor Sa5, it recognizes that all of the first tape 7p has been conveyed to the downstream side and the stopper 24a is located at the stopper release position P7.

[0088] Next, in order to convey the second tape 7s to the third conveyance path 20e, the feeder control unit 28 drives the second tape conveyance unit 23 to convey the second tape 7s to the downstream side. In this way, the second tape 7s can be continuously conveyed following the first tape 7p.

[0089] Next, with reference to FIG. 19, the configuration of the control system of the tape feeder 6 will be described. The feeder control unit 28 included in the tape feeder 6 is composed of, for example, an arithmetic unit composed of a semiconductor element such as a processor or an FPGA, a storage device composed of, for example, a hard disk (HDD), a memory, or an SSD, and further includes a communication unit 28a. The functions of the feeder control unit 28 may be configured by hardware only, or may be realized by combining hardware and software. The feeder control unit 28 may realize a predetermined function by reading data and programs stored in the storage device and performing various arithmetic processes. The communication unit 28a is a communication interface and transmits and receives signals and data to and from the mounting control unit 10 included in the component mounting device 1. Based on the detection results of the first sensor Sa1, the second sensor Sa2, and the third sensor Sa3, the feeder control unit 28 controls the first motor 21b and the second motor 23a to execute the tape conveyance operation of the carrier tape 7 and the tape release operation of the tape holding release mechanism 34 according to a predetermined control pattern.

[0090] Also, the feeder control unit 28 drives and controls the solenoid 46 based on the collation result of the identifier 8a of the reel 8 from the mounting control unit 10. Further, when the feeder control unit 28 receives a detection signal from the fourth sensor Sa4, it recognizes that the shutter 27a is opened and the second tape 7s is being conveyed below the shutter 27a along the first conveyance path 20c.

[0091] Also, when the feeder control unit 28 can no longer receive the detection signal from the fifth sensor Sa5, it recognizes that the first tape 7p has been completely conveyed downstream from the second conveyance path 20d.

[0092] Next, with reference to FIGS. 2 and 20, the tape conveyance operation in the tape feeder 6 will be described. FIG. 20 is a flowchart showing the flow of tape supply of the tape feeder 6.

[0093] In step S1, with the carrier tape 7 not being supplied to the tape feeder 6, the operator inserts the carrier tape 7 into the first conveyance path 20c through the insertion port 20a.

[0094] Also, in parallel with step S1, the verification unit 10a of the mounting control unit 10 verifies the identifier 8a of the reel 8 read from the reader device 15 with the component information stored in the storage unit 10b, and determines whether the component of the carrier tape 7 inserted into the first conveyance path 20c is the correct component. The mounting control unit 10 transmits the verification result by the verification unit 10a to the feeder control unit 28.

[0095] In step S2, when the feeder control unit 28 receives the verification result (a signal indicating agreement) that the component of the carrier tape 7 is the correct component from the mounting control unit 10, it drives the solenoid 46 to release the lock of the lock unit 45. When the lock is released, the operator further inserts the carrier tape 7 into the tape conveyance path 20 through the first conveyance path 20c. When the first sensor Sa1 detects the leading end of the carrier tape 7, it transmits a detection signal to the feeder control unit 28. Also, when the feeder control unit 28 receives the verification result (a signal indicating disagreement) that the component of the carrier tape 7 is not the correct component from the mounting control unit 10, it displays on the operation display panel 29 that it is not the correct component and notifies the operator.

[0096] In step S3, when the feeder control unit 28 receives a detection signal from the first sensor Sa1, it rotates the second motor 23a forward. Thereby, the second sprocket 23g rotates to convey the carrier tape 7 in the downstream direction. Note that the feeder control unit 28 may perform step S3 at the timing when the lock of the lock unit 45 is released, rotate the second motor 23a forward, and convey the carrier tape 7 in the downstream direction.

[0097] When the carrier tape 7 is conveyed in the downstream direction within the tape conveyance path 20 and the second sensor Sa2 detects the leading end of the carrier tape 7, it transmits a detection signal to the feeder control unit 28.

[0098] In step S4, when the feeder control unit 28 receives a detection signal from the second sensor Sa2, it reduces the rotational speed of the second motor 23a and stops the second motor 23a after a predetermined period of time has elapsed. As a result, the carrier tape 7 has reached the first sprocket 21a. Next, when the feeder control unit 28 rotates the first motor 21b forward to rotate the first sprocket 21a, the first sprocket 21a engages with the carrier tape 7. Therefore, the carrier tape 7 is delivered to the first sprocket 21a. The feeder control unit 28 rotationally drives the first motor 21b to pitch-feed the carrier tape 7 by a predetermined pitch with the first sprocket 21a. In this way, the feeder control unit 28 switches the sprocket that conveys the carrier tape 7.

[0099] When the carrier tape 7 is pitch-fed by the first sprocket 21a and the third sensor Sa3 detects the leading end of the carrier tape 7, it transmits a detection signal to the feeder control unit 28. When the feeder control unit 28 receives the detection signal from the third sensor Sa3, it stops the first motor 21b.

[0100] Next, in step S5, the feeder control unit 28 rotates the second motor 23a in the reverse direction to rotate the ratchet gear 35a clockwise. As a result, the lever 36 of the tape holding release mechanism 34 swings, the second support portion 31 of the tape holding portion 26 moves upward, and the carrier tape 7 drops onto the second conveyance path 20d.

[0101] Next, in step S6, the feeder control unit 28 rotates the second motor 23a in the reverse direction for a predetermined period of time and then stops the second motor 23a. At this timing, the feeder control unit 28 performs the peeling operation of the carrier tape 7.

[0102] Next, in step S7, the feeder control unit 28 rotates the second motor 23a forward to rotate the ratchet gear 35a clockwise. As a result, the lever 36 of the tape holding release mechanism 34 swings back to its original position, and the second support portion 31 of the tape holding portion 26 moves downward and returns to the tape holding position, which is the original position. Accordingly, since the first tape 7p previously inserted into the tape feeder 6 is engaged with the first sprocket 21a through the tape conveyance path 20 from the second conveyance path 20d, the second tape 7s for supplying the next component can always be inserted into the tape holding portion 26 while the components of the first tape 7p are being taken out by the mounting head 4 of the component mounting apparatus 1.

[0103] According to the tape feeder 6 of the present embodiment, the first conveyance path 20c into which the carrier tape 7 is inserted and the second conveyance path 20d located below the first conveyance path 20c are each provided on the upstream side, and the tape feeder 6 includes a tape conveyance path 20 in which the second conveyance path 20d and the first conveyance path 20c merge to guide the running of the carrier tape 7 in the downstream direction. The tape feeder 6 further includes a first tape conveyance unit 21 that sequentially conveys the carrier tape 7 on the tape conveyance path 20 downstream of the position P2 where the first conveyance path 20c and the second conveyance path 20d merge to the component take-out position P1 of the tape conveyance path 20, and a tape holding portion 26 that holds the carrier tape 7 at at least a part of the first conveyance path 20c. The tape feeder 6 further includes a second tape conveyance unit 23 that conveys the carrier tape 7 held by the tape holding portion 26 in the downstream direction of the tape conveyance path 20, and a tape holding release mechanism 34 that drops the carrier tape 7 held by the tape holding portion 26 from the first conveyance path 20c to the second conveyance path 20d. The tape holding release mechanism 34 operates using the power of the drive source of the second tape conveyance unit 23.

[0104] As described above, in the tape feeder 6 of the present embodiment, since the tape holding release mechanism 34 automatically drops the carrier tape 7 inserted into the first conveyance path 20c onto the second conveyance path 20d, it is possible to prevent the supply of components from stopping due to an operator forgetting to perform the tape discharging operation. As a result, the productivity of the mounting substrate can be improved, and the supply of components to the component mounting apparatus can be automated or labor-saving.

[0105] Further, the second tape conveyance unit 23 of the present embodiment includes, as a drive source, a second motor 23a that can rotate forward and backward. When the second motor 23a rotates forward, the second tape conveyance unit 23 conveys the carrier tape 7 in the downstream direction of the tape conveyance path 20, and when the second motor 23a rotates backward, the tape holding release mechanism 34 is driven.

[0106] Accordingly, since the second motor 23a of the second tape conveyance unit 23 that conveys the carrier tape 7 is used as the drive source for the tape holding release mechanism 34, it is possible to save space within the tape feeder 6.

[0107] Further, the tape holding unit 26 of the present embodiment is displaceable from the holding position that holds the carrier tape 7 to the release position P3 where the holding of the carrier tape 7 is released, and the tape holding release mechanism 34 displaces the tape holding unit 26 to the release position P3.

[0108] Further, the tape holding release mechanism 34 of the present embodiment includes a ratchet mechanism 35 that rotates by the driving force of the second motor 23a, and a lever 36 that swings by the ratchet mechanism 35. The tape holding unit 26 is displaced to the holding position or the release position P3 by the swinging of the lever 36.

[0109] Accordingly, since the lever 36 is swung by the ratchet mechanism 35, the tape holding unit 26 can be maintained at the holding position or the release position P3 as long as the rotation direction of the second motor 23a does not change.

[0110] Further, according to the tape feeder 6 of the present embodiment, a feeder control unit 28 is provided that drives the tape holding release mechanism 34 at a timing after the carrier tape 7 conveyed by the second tape conveyance unit 23 is delivered to the first tape conveyance unit 21.

[0111] Thereby, even when the carrier tape 7 is released from the first conveyance path 20c to the second conveyance path 20d, since it is after the carrier tape 7 has been delivered to the first tape conveyance unit 21, the carrier tape on the second conveyance path can be pitch-fed by the first tape conveyance unit 21 as a preceding tape. Also, since the carrier tape 7 as a subsequent tape can be inserted into the tape holding unit 26 which is a part of the first conveyance path 20c, the productivity of the mounting substrate can be improved. Note that the delivery of the carrier tape 7 from the second tape conveyance unit 23 to the first tape conveyance unit 21 may be a state where both the first sprocket 21a and the second sprocket 23g of the first tape conveyance unit 21 are engaged with the downstream side and the upstream side of the carrier tape 7 respectively, or may be a state where only the first sprocket 21a of the first tape conveyance unit 21 is engaged with the carrier tape 7.

[0112] Further, according to the tape feeder 6 of the present embodiment, a first sensor Sa1 that detects that the carrier tape 7 has been inserted into the tape conveyance path 20, and a second sensor Sa2 that is disposed on the downstream side of the tape conveyance path 20 from the first sensor Sa1 and detects that the carrier tape 7 has reached are provided. The tape feeder 6 further includes a third sensor Sa3 that is disposed on the downstream side of the tape conveyance path 20 from the second sensor Sa2 and detects that the carrier tape 7 has reached the component take-out position P1. The feeder control unit 28 activates the second tape conveyance unit 23 based on the detection result of the first sensor Sa1 detecting the carrier tape 7, stops the second tape conveyance unit 23 at a predetermined timing after the second sensor Sa2 detects the carrier tape 7, and further activates the first tape conveyance unit 21.

[0113] Accordingly, the position of the carrier tape 7 conveyed along the conveyance path 20 can be detected, and the carrier tape 7 can be accurately delivered from the second tape conveyance unit 23 to the first tape conveyance unit 21.

[0114] Also, the feeder control unit 28 of the present embodiment stops the first tape conveyance unit 21 based on the detection result of the third sensor Sa3 detecting the carrier tape 7, and drives the tape holding release mechanism 34. Accordingly, after the downstream side of the carrier tape 7 is delivered to the first tape conveyance unit 21, the first tape conveyance unit 21 stops and the tape holding release mechanism 34 is driven, so that it is possible to prevent the carrier tape 7 from being released during conveyance, and the path change of the carrier tape 7 can be accurately performed.

[0115] Further, according to the tape feeder 6 of the present embodiment, the carrier tape 7 in which components are stored is conveyed to supply the components to the component mounting device 1. The tape feeder 6 includes a shutter 27a provided downstream of the second sprocket 23g in the first conveyance path 20c to prevent the carrier tape 7 from being conveyed downstream from a predetermined position, information on the components stored in the carrier tape 7, and a feeder control unit 28 that drives and controls the second tape conveyance unit 23 based on the result of comparison between the information on the components to be supplied in advance. The shutter 27a is moved by the carrier tape 7 conveyed by the second tape conveyance unit 23 from the tape stop position P4 that stops the progress of the carrier tape 7 to the retracted position P5 away from the tape stop position P4.

[0116] Accordingly, based on the result of comparison between the information on the components stored in the carrier tape 7 and the information on the components to be supplied, the feeder control unit 28 can control the conveyance of the carrier tape 7, so that it is not necessary for the operator to further insert the carrier tape 7 after the comparison, the waiting time of the operator can be reduced, and the work efficiency can be improved.

[0117] In addition, the tape feeder 6 of the present embodiment includes a locking portion 45 that locks the shutter 27a, and the feeder control unit 28 causes the locking portion 45 to release the lock on the shutter 27a based on the result of the verification, and conveys the carrier tape 7 to the second tape conveyance unit 23.

[0118] As a result, the feeder control unit 28 causes the locking portion 45 to release the lock on the shutter 27a based on the result of the verification, so that only the carrier tape 7 storing the correct parts can be conveyed.

[0119] Further, according to the tape feeder 6 of the present embodiment, it includes a fourth sensor Sa4 that detects the displacement of the shutter 27a. The unlocked shutter 27a is displaced by the carrier tape 7 conveyed along the first conveyance path 20c, and the feeder control unit 28 recognizes that the carrier tape 7 has been replenished to the tape feeder 6 based on the fact that the fourth sensor Sa4 has detected the displacement of the shutter 27a.

[0120] As a result, even after all the parts of the first tape 7p have been supplied, the feeder control unit 28 recognizes that the second tape 7s has already been set, so that the parts can be continuously supplied to the component mounting device 1.

[0121] Further, according to the tape feeder 6 of the present embodiment, it has a contact portion 24aa that contacts the leading end of the second tape 7s at a predetermined position on the first conveyance path 20c, a stop position P6 that stops the second tape 7s at the predetermined position, a stopper 24a that can move from the stop position P6 to a stopper release position P7 where the second tape 7s can be conveyed downstream, and a lever 24b that moves the stopper 24a to the stop position P6 and the stopper release position P7. When moving from the stop position P6 to the stopper release position P7, the contact portion 24aa moves away from the leading end of the second tape 7s along the conveyance direction of the second tape 7s.

[0122] Accordingly, when the abutting portion 24aa moves to the stopper release position P7, it is possible to prevent the abutting portion 24aa from biting into the second tape 7s, and the second tape 7s can be smoothly conveyed.

[0123] Further, according to the tape feeder 6 of the present embodiment, the stopper 24a has a fulcrum 24ac that rotatably supports the stopper 24a, the abutting portion 24aa is disposed on the downstream side in the conveyance direction of the second tape 7s with respect to the fulcrum 24ac, and the lever 24b rotates the stopper 24a upward.

[0124] Accordingly, when the abutting portion 24aa moves from a predetermined position to the stopper release position P7, it can appropriately separate from the tip of the second tape 7s along the conveyance direction of the second tape 7s.

[0125] Further, according to the tape feeder 6 of the present embodiment, the lever 24b has a tip portion 24bb including a link, and the stopper 24a has a tip portion 24ab that receives power from the tip portion 24bb.

[0126] Accordingly, the driving force of the lever 24b can be appropriately transmitted to the stopper 24a.

[0127] The present disclosure has been fully described in connection with preferred embodiments with reference to the accompanying drawings. However, various modifications and variations will be apparent to those skilled in the art. Such modifications and variations are to be understood as being included therein as long as they do not depart from the scope of the present disclosure as defined by the appended claims. Also, changes in the combination and order of elements in each embodiment can be realized without departing from the scope and spirit of the present disclosure.

[0128] (1) In the above embodiment, the tape holding release mechanism 34 presses down the movable member 33 with the lever 36, but it is not limited to this. As shown in FIGS. 21 and 22, the movable member 33 may be lifted using a link mechanism by the lever 36. In FIG. 21, the movable member 33 is at a position where the carrier tape 7 is held by the second support portion 31. In FIG. 22, the movable member is at a position where it is lifted by the lever 36 and falls from the second support portion 31.

[0129] (2) In the above embodiment, when the movable member moves upward, the carrier tape 7 held by the tape holding portion 26 is detached, but it is not limited to this. For example, the vertical movement by the lever 36 may be converted into a horizontal movement using a cam mechanism. As shown in FIG. 23, the tape holding portion 26A includes a left side wall 32a to which the first support portion 30 is fixed and a right side wall 32b to which the second support portion 31 is fixed. FIG. 23 is an explanatory diagram for explaining the release of the carrier tape 7 in a modified example. (a) shows a state in which the carrier tape 7 is held, (b) shows a state in which the carrier tape 7 falls due to the displacement of the left side wall 32a and the right side wall 32b, and (c) shows a state in which the left side wall 32a and the right side wall 32b return to the tape holding position which is the original position. The tape holding release mechanism 34 displaces the left side wall 32a and the right side wall 32b, thereby displacing the first support portion 30 and the second support portion 31 to a release position P3 laterally separated from the first transport path 20c.

[0130] In this way, when the carrier tape 7 is dropped by the displacement of the left side wall 32a and the right side wall 32b of the tape holding portion 26A, the lengths of the first support portion 30 and the second support portion 31 can be increased, so it is suitable for transporting a wide carrier tape 7.

[0131] Note that by appropriately combining any of the above-described various embodiments and modified examples, the respective effects can be achieved.
