Description

This disclosure relates to a component supply device that supplies components to a component mounting device.

Conventionally, tape feeders are known that can continuously supply a succeeding carrier tape (successor tape) to a component removal position after a preceding carrier tape (leading tape) that contains components.

For example, the tape feeder described in Patent Document 1 is provided with a tape holding unit on the upstream side of the tape transport path that holds the trailing tape whose tip is inserted into the tape inlet. The tape holding unit has a tape holding portion that can be displaced vertically by the operator, and is configured so that the trailing tape being held can be dropped downward by displacing the tape holding portion vertically.

In this tape feeder, when the leading tape is discharged and the trailing tape becomes the leading tape and the supply of parts begins, the worker operates the tape holding unit to drop the leading tape from the tape holding unit and correct the position of the leading tape. This makes it possible to replenish the trailing tape. After that, a new trailing tape is held by the tape holding unit and its leading end is inserted into the tape inlet, completing the carrier tape replenishment work.

JP 2019-117820 A

However, in conventional tape feeders, before inserting the carrier tape into the tape feeder, a check is sometimes performed to see if the carrier tape contains the components to be supplied. Only when a correct check result is obtained, the shutter opens and the carrier tape can be inserted. This requires the operator to insert the carrier tape before and after the check, which results in waiting time for the operator during the check, making it a cumbersome task.

Therefore, the objective of this disclosure is to provide a parts supply device that improves productivity by solving the above-mentioned conventional problems.

The component supply device disclosed herein is a component supply device that transports a carrier tape containing components to supply the components to a component mounting device, and includes a tape transport path that guides the transport of the carrier tape, a tape transport unit that has a sprocket that engages with the carrier tape and transports the carrier tape, a shutter that is provided downstream of the sprocket in the tape transport path and prevents the carrier tape from being transported downstream from a predetermined position, and a control unit that drives and controls the tape transport unit based on the result of comparing information on the components stored in the carrier tape with predetermined information on the components to be supplied, and the shutter moves from a tape stop position where the advancement of the carrier tape is stopped to a waiting position away from the tape stop position by the carrier tape transported by the tape transport unit.

This disclosure provides a parts supply device that improves productivity.

Below, exemplary embodiments of the component mounting device according to the present disclosure will be described with reference to the attached drawings. The present disclosure is not limited to the specific configurations of the following embodiments, and configurations based on similar technical ideas are included in the present disclosure.

(Embodiment)
The configuration of a component mounting apparatus 1 according to an embodiment of the present disclosure will be described with reference to Fig. 1. In Fig. 1, the X direction (the direction perpendicular to the paper surface in Fig. 1) in the board transport direction and the Y direction (the left-right direction in Fig. 1) perpendicular to the board transport direction are shown as two axial directions perpendicular to each other in a horizontal plane. Also, the Z direction (the up-down direction in Fig. 1) is shown as a height direction perpendicular to the horizontal plane.

The configuration of the component mounting device 1 will be described with reference to Figure 1. The component mounting device 1 manufactures mounted boards with components mounted on them. A board transport mechanism 2 provided on the upper surface of a base 1a transports a board 3 in the X direction and positions and holds it. A mounting head 4 that moves horizontally (X direction, Y direction) by a head movement mechanism (not shown) is installed above the board transport mechanism 2. A plurality of tape feeders 6 are attached to the top of a carriage 5 connected to the base 1a to the side of the board transport mechanism 2, lined up in the X direction.

A reel holder 9 is provided at the front of the cart 5 and below the tape feeder 6, which rotatably supports a reel 8 on which a carrier tape 7 is wound that stores the components to be supplied to the component mounting device 1. The tape feeder 6 transports the carrier tape 7 stored on the reel 8 in the tape feed direction to supply the components to a component removal position P1 by the mounting head 4. An identifier 8a that identifies the components stored on the carrier tape 7 is affixed to the reel 8. The identifier 8a is, for example, a two-dimensional barcode or an RFID tag.

The component mounting device 1 is equipped with a mounting control unit 10 that controls the board transport mechanism 2, the mounting head 4, and the head movement mechanism. The mounting control unit 10 sends a component supply command to the tape feeder 6, controls the mounting head 4 and the head movement mechanism, and executes a component mounting operation in which the mounting head 4 picks up the components supplied to the component pick-up position by the tape feeder 6, and transfers and mounts them to the mounting point of the board 3 held by the board transport mechanism 2. In this way, the tape feeder 6 is a component supply device that supplies components stored on the carrier tape 7 to the component mounting device 1. The components stored on the carrier tape 7 are, for example, chip-type electronic components. A freely openable main body cover 11 is installed above the cart 5 to cover the moving mechanisms such as the mounting head 4 so that the operator does not touch them during operation.

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, a calculation device such as a processor or FPGA, and a memory or SSD.

The memory unit 10b stores information about parts to be replenished to the tape feeder 6. The collation unit 10a collates the information about the identifier 8a read by the reader device 15 with the information about the parts to be replenished stored in the memory unit 10b. If the collation unit 10a determines that the information about the identifier 8a matches the information about the parts to be replenished, it transmits a signal indicating a match as a collation result to the feeder control unit 28. If the collation unit 10a determines that the information about the identifier 8a does not match the information about the parts to be replenished, it transmits a signal indicating a mismatch as a collation result to the feeder control unit 28.

In FIG. 1, a collection box 12 is provided below the cart 5 to collect empty carrier tape 7 that has had parts removed by the mounting head 4 and is discharged from the rear of the tape feeder 6. A discharge chute 13 is provided at the rear of the cart 5 to guide the empty carrier tape 7 discharged from the tape feeder 6 to the collection box 12. A cutting unit 14 is provided on the discharge chute 13 to cut the empty carrier tape 7 to a predetermined length. The empty carrier tape 7 discharged from the tape feeder 6 is cut by the cutting unit 14 and collected in the collection box 12.

Tape feeder
Next, the configuration of the tape feeder 6 will be described with reference to Figures 2 and 3. Figure 2 is a schematic diagram of the tape feeder 6 according to the embodiment. Figure 3 is a partially enlarged view of the tape feeder 6.

The tape feeder 6 includes a tape transport path 20, a first tape transport section 21, a second tape transport section 23, a tape holding section 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 transport path 20, and an ejection port 20b for ejecting the carrier tape 7 from the tape transport path 20.

The tape transport path 20 guides the carrier tape 7, which is 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 then to the discharge port 20b.

The insertion port 20a opens on the upstream side of the tape feed direction of the tape feeder 6 (left side in FIG. 2). The discharge port 20b opens on the downstream side of the tape feed direction (right side in FIG. 2). The tape transport path 20 is connected from the insertion port 20a to the discharge port 20b. The mounting head 4 removes the component at a component removal position P1 provided midway along the tape transport path 20.

In the process of continuously performing component mounting work, a plurality of carrier tapes 7 are sequentially inserted from the insertion port 20a and supplied to the tape feeder 6, with each carrier tape 7 stored on one reel 8 being a unit lot. In the following, as necessary, of the two carrier tapes 7 introduced from the insertion port 20a and fed along the tape feed path 20, the carrier tape 7 fed first will be referred to as the first tape 7p, and the carrier tape 7 fed after the first tape 7p will be referred to as the second tape 7s (see FIG. 3). The tape feed path 20 has a first feed path 20c into which the carrier tape 7 is inserted on the upstream side, a second feed path 20d located below the first feed path 20c, and a third feed path 20e extending from the joining position P2 of the second feed path 20d and the first feed path 20c to the discharge port 20b.

The first tape transport unit 21 transports the carrier tape 7 to the component removal position P1 on the downstream side of the tape transport path 20. The first tape transport unit 21 includes a first sprocket 21a that engages with the carrier tape 7 and a first motor 21b that rotates and drives the first sprocket 21a. A tape cover 22 is attached above the first tape transport unit 21, which holds the carrier tape 7 from above and has a peeling blade that exposes the components stored in the carrier tape 7. An opening is formed in the tape cover 22 at a position corresponding to the component removal position P1. When the carrier tape 7 runs along the underside of the tape cover 22 by the first sprocket 21a, the components are exposed by the peeling blade, and the exposed components are transported to an opening formed downstream, i.e., the component removal position P1. The method for exposing the components stored in the carrier tape 7 may be a method (full peeling method) in which a pair of rollers (not shown) is placed downstream of the component removal position P1 on the tape transport path 20, and the top tape sealing 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.

The second tape transport unit 23 sends the carrier tape 7 inserted from the insertion port 20a to the first transport path 20c to the first tape transport unit 21. The second tape transport unit 23 is disposed on the upstream side of the tape transport path 20. The second tape transport 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.

The output gear 23aa of the second motor 23a engages with the first gear 23b. The second gear 23c is rotatably arranged coaxially with the first gear 23b and engages with the third gear 23d. The third gear 23d engages with the fourth gear 23e, which 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.

The tape transport path 20 has a first transport path 20c and a second transport path 20d on the upstream side. The first transport path 20c and the second transport path 20d join at position P2. The carrier tape 7 supplied to the tape feeder 6 is first transported by the second tape transport unit 23 along the first transport path 20c to the downstream side of the tape transport path 20. When the carrier tape 7 is eventually transported to the first tape transport unit 21, the carrier tape 7 is moved from the first transport path 20c to the second transport path 20d as the preceding first tape 7p. As a result, the first tape 7p is transported from the second transport path 20d through the third transport path 20e to the downstream of the tape transport path 20, so that the next second tape 7s can be inserted into the first transport path 20c.

The tape feeder 6 includes a tape stopper section 24, a shutter unit 27, and a lock section 45, each of which is disposed below the second tape transport section 23. The tape feeder 6 also includes a first sensor Sa1, a second sensor Sa2, and a third sensor Sa3.

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

The second sensor Sa2 detects that the carrier tape 7 traveling along the tape transport path 20 has reached just before the component removal position P1. Therefore, the second sensor Sa2 is disposed downstream of the tape transport path 20 from the first sensor Sa1 and upstream of the tape transport path 20 from the third sensor Sa3.

The third sensor Sa3 detects that the carrier tape 7 traveling on the tape transport path 20 has reached the component removal 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 transport section. The first sensor Sa1 to the third sensor Sa3 are each optical sensors that detect the presence or absence of the carrier tape 7, and are, for example, color sensors or photo sensors.

The tape holding unit 26 supports the carrier tape 7 in at least a portion of the first transport path 20c, and maintains the orientation in which the carrier tape 7 is transported. See FIG. 4. The tape holding unit 26 includes a first support unit 30, a second support unit 31, a plate-like member 32, and a movable member 33. For convenience, one side will be referred to as the left and the other side as the right, facing the downstream direction in which the carrier tape 7 is transported in the tape feeder 6, as shown in FIG. 4.

The first support part 30 supports one side of the carrier tape 7 in the width direction from below. The first support part 30 is formed on the right side of the plate-shaped member 32. The second support part 31 supports the other side of the carrier tape 7 from below.

The plate-shaped member 32 extends in the tape feed direction and the vertical direction (Z direction). The inner surface (right side surface) of the plate-shaped member 32 is a guide surface that guides the left side surface of the carrier tape 7. The plate-shaped member 32 is fixed to the side wall of the tape feeder 6.

The movable member 33 has a plate-like shape and is connected so that it can swing up and down around the rotation shaft 26a. The inner surface of the movable member 33 is a guide surface that guides the right side surface of the carrier tape 7.

A handle 38 equipped with a lever that an operator can operate with his/her finger is formed on the top of the movable member 33. When the operator lifts 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 can be displaced in the vertical direction relative to the plate-like member 32 to which it is fixed (see FIG. 11).

In FIG. 4, a rotating shaft 39 having a center of rotation 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 rotating shaft 39 via a one-way clutch 40. A plurality of pins 41a are provided on the left side of the outer circumferential surface of the second sprocket 23g (i.e., the side closer to the plate-like member 32). When the movable member 33 is in the initial position, the pins 41a of the second sprocket 23g engage with feed holes 7h formed in the carrier tape 7 whose underside is supported by the first support portion 30 and the second support portion 31.

The first support part 30 supports the side of the carrier tape 7 on which the feed hole 7h is formed from below. The second sprocket 23g, which is attached to the horizontal rotating shaft 39 via a one-way clutch 40, constitutes a locking part that engages with the feed hole 7h of the carrier tape 7 to lock the carrier tape 7 to the first support part 30.

The one-way clutch 40 allows the second sprocket 23g to rotate when the carrier tape 7 engaged with the second sprocket 23g moves on the tape holding portion 26 toward the insertion opening 20a, but does not allow rotation in the opposite direction. This prevents the carrier tape 7 from falling off the tape feeder 6. In this way, the movable member 33 is fitted with the second sprocket 23g, which is attached to a rotating shaft 39 with a horizontal axis of rotation via a one-way clutch 40.

At a position above the first support portion 30 on the inner surface of the plate-like member 32, a protrusion 42 is formed that protrudes inward from the plate-like member 32. The lower end of the protrusion 42 is formed with a taper 42a having a slope that approaches the inner surface of the plate-like member 32 downward (a slope that moves away from the right side surface of the plate-like member 32 upward). In other words, the horizontal width of the lower end of the protrusion 42 narrows as it moves downward.

In FIG. 5, the downstream end of the second support part 31 is located upstream of the downstream end of the first support part 30. Also, on the downstream side of the second support part 31, a notch part 31a is formed with a slope whose side approaches the inner surface of the movable member 33 as it approaches the downstream side. That is, one end of the second support part 31 on the insertion port 20a side (downstream side) becomes narrower in the horizontal direction as it approaches the insertion port 20a side.

Next, the configuration of the tape holding release mechanism 34 will be described with reference to Figures 6 to 10. Figures 6 to 10 are side views showing the configuration of the second tape transport section 23 of the tape feeder 6 and the tape holding release mechanism 34.

The tape retention release mechanism 34 drops the carrier tape 7 held by the tape holding unit 26 on the first transport path 20c to the second transport path 20d. The tape retention release mechanism 34 operates using the power of the second motor 23a of the second tape transport unit 23. The tape retention 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.

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.

The lever 36 is, for example, L-shaped, with a ratchet claw 35b formed at one end and connected at the other end to the downstream end of the movable member 33 of the tape holding section 26. A rotating shaft 36a is provided at the center of the lever 36, and the lever 36 is attached to the tape feeder 6 via the second motor 23a so as to be swingable around the rotating shaft 36a.

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

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

When the second motor 23a further rotates in the reverse direction, as shown in FIG. 9, the ratchet gear 35a pushes down the ratchet pawl 35b of the lever 36, causing the lever 36 to rotate counterclockwise. This causes the lever 36 to push down the downstream end of the movable member 33 of the tape holding section 26. As a result, the movable member 33 rotates clockwise around the rotation shaft 26a, and the second support section 31 moves upward to the release position P3.

Furthermore, when the second motor 23a continues to rotate in the reverse direction, as shown in FIG. 10, the ratchet gear 35a continues to act to push down the ratchet pawl 35b of the lever 36, so that the ratchet pawl 35b of the lever 36 does not engage with the ratchet gear 35a. Therefore, the lever 36 remains in a state where it pushes down the downstream end of the movable member 33 of the tape holding part 26, and the second support part 31 of the tape holding part 26 remains in the upper release position P3.

Next, when the second motor 23a rotates forward, the ratchet gear 35a acts to lift the ratchet pawl 35b of the lever 36, so that 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 of the movable member 33 of the tape holding part 26 upward, and the second support part 31 moves to its original position, the tape holding position.

Next, referring to FIG. 11, the function of releasing the carrier tape 7 on the first transport path 20c from the tape holding unit 26 will be described. As shown in FIG. 11(a), the carrier tape 7 is held by the tape holding unit 26 with the movable member 33 in the initial position and the second support unit 31 at the same height as the first support unit 30. When releasing the carrier tape 7 on the first transport path 20c from the tape holding unit 26, the feeder control unit 28 reverses the second motor 23a of the second tape transport unit 23. This causes the movable member 33 to rise together with the second support unit 31 and the second sprocket 23g. The movable member 33 can also rise if the operator manually holds the handle 38 and lifts it upward.

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. As the movable member 33 rises further, the pin 41a of the second sprocket 23g comes out of the feed hole 7h of the carrier tape 7. As shown in FIG. 11(c), as the carrier tape 7 rises further together with the movable member 33, the carrier tape 7 is pushed by the taper 42a of the protrusion 42 and displaced to a position (right side) where it does not overlap with the first support portion 30, twisting counterclockwise.

As shown in FIG. 11(d), as the movable member 33 rises further, the twist in the carrier tape 7 increases, and eventually the right end of the carrier tape 7 slips off the second support part 31. At this time, the right end of the carrier tape 7 slips off reliably starting from the notch 31a on the downstream side of the second support part 31. In addition, since the left end of the carrier tape 7 has been displaced to the right by the protrusion 42, the carrier tape 7 falls downward without getting caught on the first support part 30 (shown by the dotted line in the figure).

The carrier tape 7 released from the tape holding unit 26 moves to the second transport path 20d formed below the first transport path 20c as the first tape 7p (see FIG. 3). The carrier tape 7 is released from the tape holding unit 26, for example, before the carrier tape 7 is inserted into the tape feeder 6 and a component is removed from the component removal position P1. Once the carrier tape 7 (first tape 7p) has been released from the tape holding unit 26, the next carrier tape 7 (second tape 7s) can be inserted into the tape holding unit 26 at any time.

<Shutter unit>
Next, the shutter unit 27 will be described with reference to Figures 14 and 15. Figure 14 is a partially enlarged view of the periphery of the shutter unit. Figure 15 is a side view showing the configuration of the shutter unit 27 and a locking portion 45.

The shutter unit 27 prevents the carrier tape 7 from moving forward until the matching of the components on the carrier tape 7 inserted into the first transport path 20c is completed. The shutter unit 27 includes a shutter 27a, a pin 27b, a coil spring 27c, and a fourth sensor Sa4.

The shutter 27a comes into contact with the carrier tape 7 to stop the advancement of the carrier tape 7. The shutter 27a includes a shutter body 27e and a plate-shaped member 27f.

The shutter body 27e has an inclined portion 27ea against which the carrier tape 7 abuts, a long hole 27eb extending in the vertical direction, and a step portion 27ec that fits into the locking portion 45. A pin 27b is inserted into the long hole 27eb, and the shutter 27a can be displaced in the vertical direction along the long hole 27eb.

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 waiting 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, the shutter 27a is lowered to the first transport path 20c, so the fourth sensor Sa4 cannot detect the plate-like member 27f. When the shutter 27a is at the waiting position P5, the shutter 27a is raised upward from the first transport path 20c, so the fourth sensor Sa4 detects the plate-like member 27f.

The coil spring 27c biases the shutter body 27e so as to push the shutter 27a downward, i.e., so that the lower end of the shutter body 27e contacts the first transport path 20c. When the carrier tape 7 is transported downstream by the second tape transport section 23, the carrier tape 7 lifts the shutter 27a against the spring force of the coil spring 27c and advances.

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

The solenoid 46 attracts the lever 47, which prevents the shutter 27a from being displaced, downstream so that the shutter 27a can 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 engages with the downstream end 47b of the lever 47. When the solenoid 46 receives a suction command from the feeder control unit 28, it displaces the plunger 46a to the suction position and displaces the lever 47 downstream. When the suction command from the feeder control unit 28 is no longer received, the solenoid 46 displaces the plunger 46a to its original release position.

The lever 47 is biased upstream, i.e., toward the shutter 27a, by a coil spring 48. When the plunger 46a of the solenoid 46 is in the released state, the upstream end 47a of the lever 47 engages with the stepped portion 27ec of the shutter body 27e. This prevents the shutter 27a from rising to the waiting position P5, and locks the movement of the shutter 27a.

When the placement control unit 10 checks the part and finds that the part matches the part to be supplied, the feeder control unit 28 sends a suction command to the solenoid 46. As a result, as shown in FIG. 14, the solenoid 46 sucks in the plunger 46a and displaces the lever 47 downstream. As a result, the upstream end 47a of the lever 47 comes off the step 27ec of the shutter body 27e, and the shutter 27a is unlocked.

Even when the shutter 27a is unlocked, the shutter 27a is still biased downward by the coil spring 27c. However, the feeder control unit 28 stops issuing the suction command to the solenoid 46 and then sends a command to transport the tape to the second tape transport unit 23, so that the carrier tape 7 is transported 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.

When the tip of the carrier tape 7 pushes the shutter body 27e upward, the plate member 27f of the shutter 27a is also displaced upward, and the fourth sensor Sa4g detects the plate member 27f. This makes it possible to detect that the carrier tape 7 passes under the shutter 27a, i.e., that the carrier tape 7 is being transported from the first transport path 20c toward the third transport path 20e.

If the component matching by the mounting control unit 10 indicates that the component does not match the component that should be supplied, the feeder control unit 28 notifies the operator, for example, via the operation display panel 29, that the set reel 8 is incorrect. When the operator recognizes that the reel 8 is incorrect, he or she lifts the handle 38 of the tape holding unit 26 and removes the incorrectly inserted carrier tape 7 from the first transport path 20c.

<Tape stopper part>
16 to 18, the configuration of the tape stopper portion 24 will be described. The tape stopper portion 24 stops the second tape 7s inserted in the first transport path 20c from proceeding to the third transport path 20e when the first tape 7p is transported along the second transport path 20d and the third transport path 20e.

The tape stopper section 24 includes a stopper 24a, a lever 24b, and a fifth sensor Sa5.

The stopper 24a is, for example, a plate-like member, and can be displaced between a stop position P6 (see FIG. 17) where the advancement of the second tape 7s is stopped, and a stopper release position P7 (see FIG. 18) where the advancement of the second tape 7s is released. The stopper 24a has an abutment portion 24aa, a tip portion 24ab, and a fulcrum 24ac. The abutment portion 24aa abuts against the tip of the second tape 7s at the stop position P6, which is a predetermined position of the first transport path 20c, and prevents the second tape 7s from moving downstream along the first transport path 20c.

The tip portion 24ab is the downstream portion of the stopper 24a and is the transmitting portion that receives the power from the lever 24b to displace the lever from the stop position P6 to the stopper release position P7.

The fulcrum 24ac is the center of rotation for displacing the stopper 24a to the stop position P6 and the stopper release position P7. The fulcrum 24ac is located above the first transport path 20c and upstream of the abutment portion 24aa.

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

The tape pressing portion 24ba presses down the first tape 7p transported along the third transport path 20e from above. The coil spring 24c is biased so that the tape pressing portion 24ba pushes it downward. As the first tape 7p advances downstream, it lifts up the tape pressing portion 24ba against the spring force of the coil spring 24c.

When the first tape 7p is lifting the tape pressing portion 24ba, the claw portion 24bc extending upward from the top of the lever 24b is detected by the fifth sensor Sa5. Also, in this state, the upstream tip portion 24bb of the lever 24b is lowered downward, and the tip portion 24bb supports the weight of the tip portion 24ab of the stopper 24a.

As shown in FIG. 18, when the first tape 7p is completely transported downstream, the tape pressing portion 24ba rotates clockwise due to the spring force of the coil spring 24c and contacts the third transport path 20e. As a result, the lever 24b rotates clockwise around 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 rotational power to the tip portion 24ab of the stopper 24a. As a result, the stopper 24a is rotated and displaced from the stop position P6 to the stopper release position P7, and the abutment portion 24aa is released from abutment against the second tape 7s. At this time, the opening direction of the abutment 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, the contact portion 24aa rotates in a direction away from the tip of the second tape 7s from the stop position P6 to the stopper release position P7, so that the contact portion 24aa is prevented from biting into the tip of the second tape 7s, and the second tape 7s is prevented from becoming clogged when the stopper 24a is released.

In addition, the rotation of lever 24b stops the detection signal from fifth sensor Sa5 from being sent to feeder control unit 28. When feeder control unit 28 stops receiving the detection signal from fifth sensor Sa5, it recognizes that first tape 7p has been transported entirely downstream and stopper 24a is in stopper release position P7.

The feeder control unit 28 then drives the second tape transport unit 23 to transport the second tape 7s downstream to transport the second tape 7s to the third transport path 20e. In this way, the second tape 7s can be transported continuously following the first tape 7p.

Next, the configuration of the control system of the tape feeder 6 will be described with reference to FIG. 19. The feeder control unit 28 provided in the tape feeder 6 is composed of, for example, a processor or an arithmetic device such as an FPGA, and a memory or an SSD, and further includes a communication unit 28a. The communication unit 28a is a communication interface, and transmits and receives signals and data with the mounting control unit 10 provided in the component mounting device 1. The feeder control unit 28 controls the first motor 21b and the second motor 23a based on the detection results of the first sensor Sa1, the second sensor Sa2, and the third sensor Sa3, and performs the tape transport operation of the carrier tape 7 and the tape release operation of the tape holding release mechanism 34 according to a predetermined control pattern.

The feeder control unit 28 also controls the drive of the solenoid 46 based on the result of matching the identifier 8a of the reel 8 from the mounting control unit 10. Furthermore, when the feeder control unit 28 receives a detection signal from the fourth sensor Sa4, it recognizes that the shutter 27a has been opened and the second tape 7s is being transported below the shutter 27a along the first transport path 20c.

In addition, when the feeder control unit 28 is no longer able to receive a detection signal from the fifth sensor Sa5, it recognizes that the first tape 7p has been completely transported downstream from the second transport path 20d.

Next, the tape transport operation of the tape feeder 6 will be described with reference to Figures 2 and 20. Figure 20 is a flowchart showing the flow of tape supply by the tape feeder 6.

In step S1, with no carrier tape 7 being supplied to the tape feeder 6, the operator inserts the carrier tape 7 into the first transport path 20c through the insertion port 20a.

In parallel with step S1, the matching unit 10a of the mounting control unit 10 matches the identifier 8a of the reel 8 read from the reader device 15 with the component information stored in the memory unit 10b to determine whether the component on the carrier tape 7 inserted into the first transport path 20c is the correct component. The mounting control unit 10 transmits the matching result by the matching unit 10a to the feeder control unit 28.

In step S2, when the feeder control unit 28 receives a comparison result (a signal indicating a match) from the mounting control unit 10 indicating that the component on the carrier tape 7 is the correct component, it drives the solenoid 46 to unlock the lock unit 45. When the lock is released, the worker further inserts the carrier tape 7 into the tape transport path 20 through the first transport path 20c, and 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. In addition, when the feeder control unit 28 receives a comparison result (a signal indicating a mismatch) from the mounting control unit 10 indicating that the component on the carrier tape 7 is not the correct component, it displays on the operation display panel 29 that it is not the correct component to notify the worker.

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

When the carrier tape 7 is transported downstream in the tape transport path 20 and the second sensor Sa2 detects the leading end of the carrier tape 7, it sends a detection signal to the feeder control unit 28.

In step S4, when the feeder control unit 28 receives a detection signal from the second sensor Sa2, it reduces the rotation speed of the second motor 23a, and stops the second motor 23a after a predetermined time has elapsed. As a result, the carrier tape 7 reaches the first sprocket 21a. Next, the feeder control unit 28 rotates the first motor 21b in the forward direction to rotate the first sprocket 21a, and 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 drives the first motor 21b to rotate and causes the first sprocket 21a to feed the carrier tape 7 at a predetermined pitch. In this way, the feeder control unit 28 switches the sprocket that transports the carrier tape 7.

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 sends 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.

Next, in step S5, the feeder control unit 28 rotates the second motor 23a in the reverse direction, causing the ratchet gear 35a to rotate clockwise. This causes the lever 36 of the tape retention release mechanism 34 to swing, and the second support portion 31 of the tape retention unit 26 to move upward, causing the carrier tape 7 to fall onto the second transport path 20d.

Next, in step S6, the feeder control unit 28 rotates the second motor 23a in the reverse direction for a predetermined 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.

Next, in step S7, the feeder control unit 28 rotates the second motor 23a in the forward direction to rotate the ratchet gear 35a clockwise. This causes the lever 36 of the tape retention release mechanism 34 to swing back to its original position, and the second support portion 31 of the tape retention unit 26 to move downward and return to its original tape retention position. As a result, the first tape 7p previously inserted into the tape feeder 6 is engaged with the first sprocket 21a through the tape transport path 20 from the second transport path 20d. Therefore, while the components on the first tape 7p are being removed by the mounting head 4 of the component mounting device 1, the second tape 7s that will supply the next component can be inserted into the tape retention unit 26 at any time.

According to the tape feeder 6 of this embodiment, the tape feeder 6 includes a tape feed path 20 having a first feed path 20c into which the carrier tape 7 is inserted and a second feed path 20d located below the first feed path 20c, on the upstream side, and the second feed path 20d and the first feed path 20c join to guide the running of the carrier tape 7 in the downstream direction. The tape feeder 6 further includes a first tape feed unit 21 that sequentially feeds the carrier tape 7 of the tape feed path 20 downstream of the position P2 where the first feed path 20c and the second feed path 20d join to the component removal position P1 of the tape feed path 20, and a tape holding unit 26 that holds the carrier tape 7 in at least a part of the first feed path 20c. The tape feeder 6 further includes a second tape transport unit 23 that transports the carrier tape 7 held by the tape holding unit 26 in the downstream direction of the tape transport path 20, and a tape retention release mechanism 34 that drops the carrier tape 7 held by the tape holding unit 26 from the first transport path 20c to the second transport path 20d. The tape retention release mechanism 34 operates using the power of the drive source of the second tape transport unit 23.

In this way, the tape feeder 6 of this embodiment has a tape retention release mechanism 34 that automatically drops the carrier tape 7 inserted into the first transport path 20c to the second transport path 20d, preventing component supply interruptions caused by an operator forgetting to release the tape. This makes it possible to improve the productivity of mounted boards and automate or reduce the labor required for component supply to component mounting devices.

The second tape transport unit 23 in this embodiment also includes a second motor 23a capable of rotating forward and reverse as a drive source. When the second motor 23a rotates forward, the second tape transport unit 23 transports the carrier tape 7 in the downstream direction of the tape transport path 20, and when the second motor 23a rotates reversely, it drives the tape holding release mechanism 34.

As a result, the second motor 23a of the second tape transport section 23 that transports the carrier tape 7 is used as the driving source for the tape retention release mechanism 34, thereby making it possible to save space within the tape feeder 6.

In addition, in this embodiment, the tape holding portion 26 can be displaced from a holding position where the carrier tape 7 is held to a release position P3 where the holding of the carrier tape 7 is released, and the tape holding release mechanism 34 displaces the tape holding portion 26 to the release position P3.

The tape holding release mechanism 34 in this embodiment also includes a ratchet mechanism 35 that rotates due to the driving force of the second motor 23a, and a lever 36 that swings due to the ratchet mechanism 35. The tape holding portion 26 is displaced to the holding position or release position P3 due to the swinging of the lever 36.

As a result, the lever 36 is swung by the ratchet mechanism 35, so that the tape holding portion 26 can be maintained in the holding position or the release position P3 as long as the direction of rotation of the second motor 23a does not change.

In addition, the tape feeder 6 of this embodiment is provided with a feeder control unit 28 that drives the tape holding release mechanism 34 at a timing after the carrier tape 7 transported by the second tape transport unit 23 is handed over to the first tape transport unit 21.

As a result, even if the carrier tape 7 is released from the first transport path 20c to the second transport path 20d, the carrier tape 7 has already been delivered to the first tape transport section 21, so the carrier tape on the second transport path can be pitch-fed by the first tape transport section 21 as a leading tape. In addition, the carrier tape 7 can be inserted as a trailing tape into the tape holding section 26, which is a part of the first transport path 20c, so the productivity of the mounting board can be improved. Note that the delivery of the carrier tape 7 from the second tape transport section 23 to the first tape transport section 21 may be in a state in which both the first sprocket 21a and the second sprocket 23g of the first tape transport section 21 are engaged with the carrier tape 7 on the downstream side and the upstream side, respectively, or in a state in which only the first sprocket 21a of the first tape transport section 21 is engaged with the carrier tape 7.

The tape feeder 6 of this embodiment includes a first sensor Sa1 that detects that the carrier tape 7 has been inserted into the tape transport path 20, and a second sensor Sa2 that is disposed downstream of the tape transport path 20 from the first sensor Sa1 and detects that the carrier tape 7 has arrived. The tape feeder 6 further includes a third sensor Sa3 that is disposed downstream of the tape transport path 20 from the second sensor Sa2 and detects that the carrier tape 7 has arrived at the component removal position P1. The feeder control unit 28 starts the second tape transport unit 23 based on the detection result of the first sensor Sa1 detecting the carrier tape 7, stops the second tape transport unit 23 at a predetermined timing after the second sensor Sa2 detects the carrier tape 7, and further starts the first tape transport unit 21.

This allows the position of the carrier tape 7 being transported along the transport path 20 to be detected, and the carrier tape 7 can be transferred with high precision from the second tape transport unit 23 to the first tape transport unit 21.

Furthermore, the feeder control unit 28 of this embodiment stops the first tape transport 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. As a result, after the downstream side of the carrier tape 7 is handed over to the first tape transport unit 21, the first tape transport unit 21 stops and the tape holding release mechanism 34 is driven, so that the carrier tape 7 can be prevented from being released during transport, and the path of the carrier tape 7 can be changed with high accuracy.

According to the tape feeder 6 of the present embodiment, the carrier tape 7 on which the components are stored is transported to supply the components to the component mounting device 1. The tape feeder 6 is provided on the first transport path 20c downstream of the second sprocket 23g, with a shutter 27a that prevents the carrier tape 7 from being transported downstream from a predetermined position, and a feeder control unit 28 that drives and controls the second tape transport unit 23 based on the result of comparing information on the components stored on the carrier tape 7 with information on the components to be supplied that has been determined in advance. The shutter 27a moves with the carrier tape 7 transported by the second tape transport unit 23 from the tape stop position P4, where the advancement of the carrier tape 7 stops, to the waiting position P5 away from the tape stop position P4.

This allows the feeder control unit 28 to control the transport of the carrier tape 7 based on the results of comparing the information on the parts stored on the carrier tape 7 with the information on the parts to be supplied, eliminating the need for the worker to further insert the carrier tape 7 after comparison, reducing the worker's waiting time and improving work efficiency.

The tape feeder 6 of this embodiment also includes a locking unit 45 that locks the shutter 27a, and the feeder control unit 28 unlocks the shutter 27a by the locking unit 45 based on the result of the comparison, and causes the second tape transport unit 23 to transport the carrier tape 7.

As a result, the feeder control unit 28 unlocks the shutter 27a by the lock unit 45 based on the result of the comparison, so that only the carrier tape 7 containing the correct parts can be transported.

The tape feeder 6 of this embodiment is also provided with a fourth sensor Sa4 that detects the displacement of the shutter 27a. The unlocked shutter 27a is displaced by the carrier tape 7 transported along the first transport 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 detection of the displacement of the shutter 27a by the fourth sensor Sa4.

As a result, even after all the components on the first tape 7p have been supplied, the feeder control unit 28 is aware that the second tape 7s has already been set, and so can continuously supply components to the component mounting device 1.

The tape feeder 6 of this embodiment has an abutment portion 24aa that abuts against the tip of the second tape 7s at a predetermined position on the first transport path 20c, a stop position P6 that stops the second tape 7s at a predetermined position, a stopper 24a that can move from the stop position P6 to a stopper release position P7 that allows the second tape 7s to be transported downstream, and a lever 24b that moves the stopper 24a to the stop position P6 and the stopper release position P7. When the abutment portion 24aa moves from the stop position P6 to the stopper release position P7, it moves away from the tip of the second tape 7s along the transport direction of the second tape 7s.

This prevents the abutment portion 24aa from digging into the second tape 7s when it moves to the stopper release position P7, allowing the second tape 7s to be transported smoothly.

In addition, according to the tape feeder 6 of this embodiment, there is a fulcrum 24ac that rotatably supports the stopper 24a, the abutment portion 24aa is located downstream of the fulcrum 24ac in the transport direction of the second tape 7s, and the lever 24b rotates the stopper 24a upward.

This allows the abutment portion 24aa to properly separate from the leading end of the second tape 7s along the transport direction of the second tape 7s when it moves from the specified position to the stopper release position P7.

Furthermore, according to the tape feeder 6 of this embodiment, the lever 24b has a tip portion 24bb that includes a link, and the stopper 24a has a tip portion 24ab that receives power from the tip portion 24bb.

This allows the driving force of lever 24b to be properly transmitted to stopper 24a.

Although the present disclosure has been fully described in connection with the preferred embodiments with reference to the accompanying drawings, various modifications and variations will be apparent to those skilled in the art. Such modifications and variations are to be understood as being included within the scope of the present disclosure as defined by the appended claims, unless they deviate therefrom. In addition, 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.

(1) In the above embodiment, the tape retention release mechanism 34 presses down the movable member 33 with the lever 36, but this is not limited to the above. As shown in Figs. 21 and 22, the movable member 33 may be lifted up by the lever 36 using a link mechanism. In Fig. 21, the movable member 33 is in a position where the carrier tape 7 is held by the second support portion 31. In Fig. 22, the movable member is lifted up by the lever 36 and is in a position where it will drop from the second support portion 31.

(2) In the above embodiment, the movable member moves upward to release the carrier tape 7 held by the tape holding portion 26, but this is not limited to the above. The vertical movement by the lever 36 may be converted into lateral movement using a cam mechanism, for example. As shown in FIG. 23, the tape holding portion 26A has 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 the modified example, where (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 have returned to their original tape holding positions. The tape holding release mechanism 34 displaces the left side wall 32a and the right side wall 32b to displace the first support portion 30 and the second support portion 31 to a release position P3 that is laterally separated from the first transport path 20c.

In this way, when the tape holding portion 26A causes the carrier tape 7 to fall due to the displacement of the left side wall 32a and the right side wall 32b, the length of the first support portion 30 and the second support portion 31 can be increased, which is suitable for transporting a wide carrier tape 7.

In addition, any of the various embodiments and modifications described above can be combined as appropriate to achieve the effects of each.

The component supply device according to the present disclosure can be applied to a component supply device that supplies components to a component mounting device that mounts the components on a board.
