Abstract
Description
Technical Field
[0001] The present invention relates to a component mounting device that mounts components supplied by a tape feeder onto a substrate, a tape feeder provided in the component mounting device, and a cassette that is attached to the tape feeder and holds a carrier tape.
Background Art
[0002] Conventionally, as a component supply unit in a component mounting device that mounts components onto a substrate, a tape feeder that supplies components to a component extraction position by transporting a carrier tape storing the components is known. The tape feeder is usually supplied in a state of being wound around the core of a reel, but it has also been proposed to supply a roll body in which the carrier tape is wound in a coreless roll shape in a case (cassette) (for example, Patent Document 1 below). Such a method of supplying the carrier tape has the advantage that a reel is not required and costs can be reduced in terms of storage and disposal of the reel.

Embodiments for Carrying Out the Invention
[0011] (Embodiment 1) FIG. 1 shows a component mounting device 1 in Embodiment 1 of the present invention. The component mounting device 1 is a device that repeatedly performs a component mounting operation of mounting a component BH on a substrate KB carried in from the upstream process side and discharging it to the downstream process side. Here, for convenience of explanation, the carrying-in and carrying-out directions of the substrate KB in the component mounting device 1 (the direction perpendicular to the paper surface in FIG. 1) are defined as the X direction, the horizontal direction orthogonal to the X direction is the Y direction, and the vertical direction is the Z direction. Also, the X direction as seen from the operator OP is the left-right direction, the Y direction is the front-back direction, and the side farther from the operator OP is expressed as "front" and the side closer to the operator OP is expressed as "rear".
[0012] In Figure 1, the component mounting device 1 is composed of a main body 2 and a component supply unit 3. The main body 2 includes a base 11, a substrate transport unit 12, a mounting head 13, a mounting head moving unit 14, and a main body control unit 15. The substrate transport unit 12 consists of a pair of belt conveyors and extends in the X direction on the base 11. The substrate transport unit 12 receives substrates KB sent from the upstream process side and positions them at predetermined work positions.
[0013] In Figure 1, the mounting head 13 is equipped with a plurality of nozzles 13N extending downward. Each nozzle 13N is capable of vertical movement relative to the mounting head 13 and rotational movement around an axis (Z-axis) along the Z direction. The mounting head 13 can generate an adhesive force at the lower end of each nozzle 13N by supplying vacuum pressure from a vacuum source (not shown) to each nozzle 13N. The mounting head moving unit 14 consists of, for example, an XY table and moves the mounting head 13 in the direction of the horizontal plane (XY plane).
[0014] In Figure 1, the parts supply unit 3 is connected to the front side of the base 11 as seen from the perspective of the operator OP. The parts supply unit 3 is equipped with a feeder trolley 21, multiple tape feeders 22, and multiple cassettes 23.
[0015] In Figure 1, the feeder trolley 21 comprises a body section 21a, a support column section 21b provided on the body section 21a, and a feeder base 21c provided on the upper part of the support column section 21b. The tape feeder 22 is detachably attached to the feeder base 21c.
[0016] In Figure 2, multiple tape feeders 22 can be mounted on the feeder base 21c in a row in the X direction. When the feeder trolley 21 is connected to the base 11, the multiple tape feeders 22 mounted on the feeder base 21c are connected to the base 11 all at once.
[0017] In Figures 1 and 2, the cassette 23 is detachably attached to the rear of each tape feeder 22. The cassette 23 consists of a case-shaped member with an upward opening, and houses a roll body RT in which the carrier tape CT is wound (Figure 3). Since the width dimension of the roll body RT is the same as the width dimension of the carrier tape CT, the width dimension of the cassette 23 is approximately the same as the width dimension of the tape feeder 22.
[0018] In Figure 3, the carrier tape CT consists of a tape-shaped material. The carrier tape CT has a large number of pockets PK arranged in a row, and a row of feed holes KH is provided parallel to the row of pockets PK. Each pocket PK contains one component BH, and each component BH is packaged inside the pocket PK by a transparent cover tape TT attached to the top surface of the carrier tape CT. When the cover tape TT is peeled off from the carrier tape CT, the component BH is exposed and can be removed from the pocket PK.
[0019] In Figure 4, the tape feeder 22 comprises a frame 31 mounted on a feeder base 21c, a transport path 32 for the carrier tape CT formed extending in the Y direction within the frame 31, a tape transport unit 35 consisting of three sprockets (introduction sprocket 33a, transport sprocket 33b, and discharge sprocket 33c) arranged along the transport path 32 and a drive unit 34 that drives these three sprockets, and a feeder control unit 36. An inlet 32a of the transport path 32 is open on the rear surface of the frame 31 (see also Figure 5), and an outlet 32b of the transport path 32 is open on the front surface of the frame 31.
[0020] The three sprockets constituting the tape transport section 35, namely the introduction sprocket 33a, the transport sprocket 33b, and the discharge sprocket 33c, each have a feed pin (not shown) on their outer circumference. These sprockets transport the carrier tape CT on the transport path 32 by rotating with the feed pins engaged with the feed holes KH of the carrier tape CT.
[0021] In Figure 4, the tape feeder 22 has a connector 37 inside the frame 31, which opens on the front of the frame 31. When the frame 31 is mounted on the feeder base 21c, the connector 37 engages with a connector (not shown) provided on the feeder base 21c. This electrically connects the feeder control unit 36 to the main unit control unit 15 via the feeder trolley 21, enabling the component mounting device 1 to control the tape feeder 22.
[0022] The feeder control unit 36 operates the drive unit 34 to rotate the introduction sprocket 33a. As the introduction sprocket 33a rotates, its feed pins engage with the feed holes KH of the carrier tape CT, and the carrier tape CT moves forward along the transport path 32 as the introduction sprocket 33a rotates.
[0023] The introduction sprocket 33a pulls the carrier tape CT inserted into the inlet 32a into the transport path 32. The transport sprocket 33b and discharge sprocket 33c rotate together with the introduction sprocket 33a to transport the carrier tape CT that has been pulled into the transport path 32.
[0024] In Figure 4, a parts removal position 22K is set between the transport sprocket 33b and the discharge sprocket 33c on the transport path 32 (see also Figure 2), and an exposed section 38 is provided slightly upstream of the parts removal position 22K. The exposed section 38 partially peels or cuts open the cover tape TT from the carrier tape CT as it moves along the transport path 32 using a blade or cutter, exposing the parts BH in the pocket PK. As a result, the parts BH in the pocket PK are exposed upwards when they reach the parts removal position 22K, and the mounting head 13 can remove the parts BH located at the parts removal position 22K using the nozzle 13N. The exposed section 38 may also employ a method that completely peels the cover tape TT from the carrier tape CT.
[0025] As described above, in Embodiment 1, the tape feeder 22 has a transport path 32 having an inlet 32a and an outlet 32b, a tape transport section 35 that transports the carrier tape CT containing the parts BH along the transport path 32 when it is inserted into the inlet 32a and supplies the parts BH to a parts retrieval position 22K along the transport path 32, and an exposure section 38 that peels off or cuts open the cover tape TT covering the upper surface of the carrier tape CT to expose the parts BH.
[0026] The tape transport unit 35 transports the carrier tape CT while pulling it out from the roll RT. After the carrier tape CT transported by the tape transport unit 35 passes the parts removal position 22K, it is discharged to the outside of the frame 31 from the discharge port 32b.
[0027] In Figure 6, the main control unit 15 comprises a component mounting operation execution unit 15a, a storage unit 15b, and a component verification unit 15c. The component mounting operation execution unit 15a controls the operation of each part constituting the main body 2 of the component mounting device 1 and the operation of each of the multiple tape feeders 22. Specifically, the component mounting operation execution unit 15a controls the substrate transport unit 12 to transport the substrate KB and position it at the work position, controls the mounting head 13 to raise and lower each of the multiple nozzles 13N and rotate them around the Z axis, and controls the holding / releasing of component BH by each nozzle 13N.
[0028] The component loading operation unit 15a also controls the loading head movement unit 14 to move the loading head 13 in the horizontal plane and performs the process of issuing commands to the feeder control unit 36 of each tape feeder 22. The feeder control unit 36 controls the drive unit 34 to operate three sprockets (introduction sprocket 33a, transport sprocket 33b, and discharge sprocket 33c) and transports the carrier tape CT to supply component BH to the component removal position 22K.
[0029] The memory unit 15b stores a production program 15P that contains the procedure for the component mounting device 1 to perform component mounting work (the work of mounting component BH onto the circuit board KB using the mounting head 13), as well as necessary component information. When the component mounting work execution unit 15a performs component mounting work, it reads the production program 15P stored in the memory unit 15b and operates each part according to the production program 15P.
[0030] When a component mounting operation is performed, the board transport unit 12 first operates to receive the board KB sent from the upstream process side and position the board KB at the work position. Once the board transport unit 12 has positioned the board KB at the work position, the mounting head moving unit 14 operates to move the mounting head 13 above the tape feeder 22 and move the nozzle 13N of the mounting head 13 above the component pick-up position 22K of the tape feeder 22. Once the nozzle 13N is positioned above the component pick-up position 22K, the mounting head 13 lowers the nozzle 13N to attract and pick up the component BH supplied to the component pick-up position 22K.
[0031] Once the mounting head 13 has attracted the component BH with the nozzle 13N, the mounting head moving unit 14 moves the mounting head 13 above the substrate KB, positioning the nozzle 13N (and thus the component BH attracted by the nozzle 13N) above the target mounting position set on the substrate KB. Once the nozzle 13N is positioned above the target mounting position, the mounting head 13 lowers the nozzle 13N to release the suction of the component BH and mounts the component BH at the target mounting position.
[0032] In this embodiment 1, the mounting head 13 picks up component BH from component pick-up position 22K and mounts it onto the circuit board KB.
[0033] The mounting head 13 repeatedly performs the mounting operation of component BH onto the circuit board KB according to the procedure described above. Once all component BH to be mounted on the circuit board KB has been mounted, the circuit board transport unit 12 operates to transport the circuit board KB to the downstream process side. This completes the component mounting work for one circuit board KB.
[0034] In the component mounting device 1 with this configuration, the tape feeder 22 and cassette 23 have distinctive features, which will be explained below. As mentioned above, the cassette 23 is detachably attached to the rear of the tape feeder 22. For this reason, as shown in Figure 7, a cassette mounting section 39 for attaching the cassette 23 is provided at the rear of the tape feeder 22.
[0035] In Figures 4 and 5, the cassette mounting section 39 is provided with engaging sections 41 (upper engaging section 41A and lower engaging section 41B) spaced apart vertically. Each engaging section 41 comprises a pair of guide plates 42 arranged in the width direction (X direction) of the frame 31, and an engaging pin 43 that extends in the X direction and is supported at both ends by these guide plates 42. The cassette mounting section 39 also includes a release section 44. The release section 44 consists of a projection that protrudes rearward from the rear surface of the frame 31 and is provided above the upper engaging section 41A.
[0036] In Figure 4, a cassette detection unit 45 and a reader 46 are provided at the rear of the frame 31 of the tape feeder 22. The cassette detection unit 45 has a detector 45T protruding rearward from the rear surface of the frame 31, and when the detector 45T is pushed downward, it detects this and transmits a detection signal to the feeder control unit 36 (Figure 6). The reader 46 transmits information read from the detected object (component information read from the wireless tag 58, as described later) to the feeder control unit 36 (Figure 6).
[0037] In Figures 2 and 4, an operation switch 47 and a display unit 48 are provided at the rear upper part of the tape feeder 22. The operation switch 47 is operated by the operator OP as needed. The operation switch 47 and the display unit 48 are electrically connected to the feeder control unit 36 (Figure 6). When the operator OP operates the operation switch 47, an operation signal is transmitted to the feeder control unit 36. The display unit 48 operates in response to a command signal output from the feeder control unit 36 and displays a predetermined information according to the status of the tape feeder 22.
[0038] In Figures 8(a) and 8(b), the cassette 23 has left and right side plates 51 (left side plate 51a and right side plate 51b), a rear plate 52 extending in the vertical direction, a bottom plate 53 extending in the front-to-back direction, and a front plate 54 extending in the vertical direction. The front plate 54 is positioned further back (towards the rear plate 52) than the respective front edges 51E of the left and right side plates 51.
[0039] In Figures 8(a) and 8(b), the left and right side panels 51, the rear panel 52, the bottom panel 53, and the front panel 54 form a hollow storage compartment 55 that opens upward. The roll body RT is inserted into and removed from the storage compartment 55 through the opening that opens upward (referred to as the "roll body entrance / exit 56").
[0040] In Figure 8(b), upper and lower engaging portions 57 (upper engaging portion 57A and lower engaging portion 57B) are provided at positions facing the front edge 51E of each of the left and right side plates 51 of the cassette 23. These upper and lower engaging portions 57 are the parts that engage with the upper and lower engaging portions 41 (upper engaging portion 41A and lower engaging portion 41B) of the cassette mounting portion 39 of the tape feeder 22, and as shown in Figure 9, they have a horizontal portion 57H that extends horizontally rearward from the front edge 51E of the left and right side plates 51, and a vertical portion 57V that extends upward from the rear end of the horizontal portion 57H.
[0041] In Figure 8(b), a wireless tag 58 is attached to the inner surface (the surface facing the right side plate 51b) of the left side plate 51a of the cassette 23, in the portion between the upper engaging portion 57A and the lower engaging portion 57B. The wireless tag 58 has information (part information) about the part BH packaged in the carrier tape CT stored in the cassette 23.
[0042] In Figures 10(a) and 10(b), a tape tip holding section 60 is provided at the front upper part of the cassette 23. The tape tip holding section 60 is composed of a fixed block 61, a movable guide 62, two holding pins 63, and a spring member 64.
[0043] In Figures 10(a) and (b), the fixed block 61 has a rectangular parallelepiped shape extending in the X direction as a whole, and its left side is fixed to the inner surface of the left side plate 51a. The movable guide 62 has a main part 62a located behind the fixed block 61, an upper extension 62b extending forward from the top of the main part 62a so as to be located above the fixed block 61, and a lower extension 62c extending forward from the bottom of the main part 62a so as to be located below the fixed block 61.
[0044] In Figure 10(b), the main portion 62a of the movable guide 62 is provided with two elongated guide grooves 62M extending in the Z direction and aligned in the Y direction. Inside each of the two guide grooves 62M is a guide pin 51T that protrudes inward from the left side plate 51a (towards the right side plate 51b). As a result, the movable guide 62 can move vertically relative to the left and right side plates 51 (and therefore relative to the fixed block 61) within the range in which the guide grooves 62M can move relative to the guide pins 51T.
[0045] In Figure 10(b), the two retaining pins 63 each extend in the Z direction, with their base ends attached to the upper part of the fixed block 61. The two retaining pins 63 are arranged side by side in the Y direction, and their spacing matches the spacing of the feed holes KH provided in the carrier tape CT. As shown in Figure 10(b), the outer diameter of each retaining pin 63 is smaller than the inner diameter of the feed holes KH, and the upper end is formed in a conical shape.
[0046] In Figure 10(b), the upper extension 62b of the movable guide 62 is provided with two pin insertion passages 62H, each extending in the Z direction to avoid interference with the two retaining pins 63. When the movable guide 62 moves relative to the fixed block 61 in the Z direction, the distance between the upper ends of the two retaining pins 63 and the upper surface of the movable guide 62 (specifically the upper surface of the upper extension 62b) changes.
[0047] In Figure 10(b), the spring member 64 is interposed between the lower extension 62c of the movable guide 62 and the fixed block 61, biasing the movable guide 62 downwards relative to the fixed block 61. When no external force is acting on the movable guide 62 (which corresponds to the state where the cassette 23 is not mounted on the tape feeder 22), the upper edges of the two guide grooves 62M of the movable guide 62 are in contact with the two guide pins 51T provided on the left side plate 51a, and the upper ends of the two retaining pins 63 each protrude upwards from the upper surface of the movable guide 62 (more specifically, the upper extension 62b) (Figures 10(b) and 11(a)). The position of the movable guide 62 in which no external force is acting on it and the upper ends of the two retaining pins 63 protrude upwards from the upper surface of the movable guide 62 will hereafter be referred to as the "carrier tape holding position".
[0048] Here, when an upward force P is applied to the movable guide 62, which is located in the carrier tape holding position, and the movable guide 62 is pushed upward by a predetermined distance H relative to the fixed block 61 (Figure 11(a) → Figure 11(b)), the upper ends of the two retaining pins 63 are each located in a position where they are retracted into the pin insertion passage 62H (hereinafter referred to as the "carrier tape release position") (Figure 11(b)). When the movable guide is in the carrier tape release position, the two spring members 64 are compressed from their original state, and when the upward force P acting on the movable guide 62 is removed, the movable guide 62 returns to the original state due to the biasing force of the two spring members 64 (Figure 11(b) → Figure 11(a)).
[0049] When cassette 23 is not mounted on tape feeder 22, the movable guide 62 is in the carrier tape holding position, and the two retaining pins 63 protrude upward from the top surface of the movable guide 62 (Figure 11(a)). When storing the roll body RT of the carrier tape CT in cassette 23, cassette 23 is removed from tape feeder 22, and the roll body RT is inserted into the storage section 55 from the roll body inlet / outlet 56. At this time, the orientation of the roll body RT is such that the leading edge of the pulled-out carrier tape CT (referred to as "tape leading edge CTs") extends forward from the top side of the roll body RT (Figures 8(b) and 12).
[0050] Once the roll RT is stored in the storage section 55, the portion of the tape leading edge CTs pulled out from the roll RT that is a certain distance from the leading edge is placed on the upper surface of the movable guide 62. At this time, two retaining pins 63 protruding from the upper surface of the movable guide 62 are inserted through two adjacent feed holes KH of the carrier tape CT. As a result, the tape leading edge CTs are held in place by the tape leading edge retaining section 60. In this state, the portion of the carrier tape CT between the portion held by the tape leading edge retaining section 60 and the leading edge of the carrier tape CT protrudes to the outside (forward) of the cassette 23. The portion of the leading edge (tape leading edge CTs) of the carrier tape CT that protrudes to the outside of the cassette 23 (the protruding portion) will be referred to below as the "tape protruding portion CTt" (Figures 8(b) and 12).
[0051] In this embodiment 1, the tape tip holding section 60 of the cassette 23 includes a movable guide 62 that supports the carrier tape CT from below, and a holding pin 63 that is inserted into the feed hole KH of the carrier tape CT supported by the movable guide 62, and is configured to hold the tip portion (tape tip portion CTs) of the carrier tape CT stored in the storage section 55.
[0052] When attaching the cassette 23 containing the roll RT to the tape feeder 22 as described above, the operator OP engages the upper and lower engaging portions 57 provided on the left and right side plates 51 of the cassette 23 with the upper and lower engaging portions 41 provided on the tape feeder 22 (Figures 13 → 14 → 15). More specifically, first, the horizontal portions 57H of the upper and lower engaging portions 57 of the cassette 23 are positioned behind the engaging pins 43 of the upper and lower engaging portions 41 of the tape feeder 22 (Figures 13 and 16(a)), and then the cassette 23 is moved forward to insert the horizontal portions 57H of the upper and lower engaging portions 57 through the engaging pins 43 of the upper and lower engaging portions 41 (Figures 13 → 14).
[0053] The engagement pins 43 of the upper and lower engagement parts 41 are inserted into the horizontal parts 57H of the upper and lower engagement parts 57. Once the engagement pins 43 reach the rear end of the horizontal part 57H, the cassette 23 is moved downwards from the tape feeder 22 (Figure 14 → Figure 15). As a result, the engagement pins 43 enter the vertical part 57V (Figure 16(b)), and the cassette 23 is mounted on the tape feeder 22 (Figure 15).
[0054] Thus, in Embodiment 1, the upper and lower engaging portions 57 of the cassette 23 function as mounting portions that are attached to the cassette mounting portion 39 of the tape feeder 22.
[0055] As described above, when the cassette 23 is mounted on the tape feeder 22, the tape projection CTt that protrudes forward from the cassette 23 enters the transport path 32 through the inlet 32a that opens on the rear surface of the tape feeder 22 (Figure 13 → Figure 14). With the cassette 23 mounted on the tape feeder 22, the carrier tape CT is positioned so that the feed pin of the introduction sprocket 33a and the feed hole KH can engage (Figure 15).
[0056] In this embodiment 1, when the cassette 23 is mounted in the cassette mounting section 39, the tip of the carrier tape CT held by the tape tip holding section 60 (more specifically, the tape protruding portion CTt, which is the portion of the tape tip CTs that protrudes to the outside of the cassette 23) is inserted into the inlet 32a provided at the rear end of the tape feeder 22. In addition, one of the multiple sprockets (introduction sprocket 33a, transport sprocket 33b, and discharge sprocket 33c) of the tape transport section 35 (introduction sprocket 33a) is positioned so that the tip of the carrier tape CT held by the tape tip holding section 60 of the cassette 23 mounted in the cassette mounting section 39 (the tape protruding portion CTt, which is the portion of the tape tip CTs that protrudes to the outside of the cassette 23) can reach it.
[0057] As described above, when the engagement pin 43 of the cassette mounting portion 39 is inserted into the horizontal portion 57H of the cassette 23 (Figure 14 → Figure 15), the release portion 44 provided on the rear surface of the tape feeder 22 enters below the tape tip holding portion 60 from the front of the cassette 23 (between the left and right side plates 51) (Figure 13 → Figure 14). Then, when the cassette 23 is pushed down relative to the tape feeder 22 (Figure 14 → Figure 15), it comes into contact with the lower surface of the movable guide 62 (specifically the lower extension portion 62c), restricting the downward movement of the movable guide 62. As a result, the fixed block 61 descends relative to the movable guide 62, and the movable guide 62 is pushed up relative to the fixed block 61 (Figure 17(a) → Figure 17(b)).
[0058] As described above, the movable guide 62 is pushed up relative to the fixed block 61, so that the movable guide 62 is in the carrier tape release position corresponding to Figure 11(b) above, and the upper end of the retaining pin 63 is retracted into the pin insertion passage 62H of the movable guide 62 (Figure 17(b)). As a result, the two retaining pins 63 are pulled downward from the two feed holes KH of the carrier tape CT (Figure 17(b)), and the tape leading ends CTs are released from being held by the tape leading end retaining part 60. This makes it possible for the tape feeder 22 to pull the carrier tape CT from the roll RT and transport it.
[0059] In this embodiment 1, the release unit 44 provided on the cassette mounting unit 39 releases the carrier tape CT from being held by the tape tip holding unit 60 of the cassette 23 mounted on the cassette mounting unit 39. Furthermore, when the upper and lower engaging parts 57 of the tape tip holding unit 60 are mounted on the cassette mounting unit 39, the holding pin 63 is released from the feed hole KH of the carrier tape CT supported by the movable guide 62.
[0060] When the cassette 23 is mounted on the cassette mounting section 39 of the tape feeder 22 as described above, the detector 45T of the cassette detection unit 45 is pushed downward by the pressing edge 57P (the lower edge of the upper part forming the upper engaged portion 57A), which is part of the right side plate 51b (Figure 16(a) → Figure 16(b)). As a result, the cassette detection unit 45 transmits a detection signal to the feeder control unit 36, and the feeder control unit 36 detects that the cassette 23 has been mounted on the cassette mounting section 39 of the tape feeder 22.
[0061] In this embodiment 1, the cassette detection unit 45 provided on the tape feeder 22 detects the cassette 23 that is mounted on the cassette mounting unit 39.
[0062] Furthermore, when the cassette 23 is mounted in the cassette mounting section 39 of the tape feeder 22, the wireless tag 58 attached to the left side plate 51a of the cassette 23 is positioned near the reader 46 located at the rear of the tape feeder 22 (Figure 15). When the feeder control unit 36 detects that the cassette 23 has been mounted in the tape feeder 22 using the cassette detection unit 45, it activates the reader 46. The reader 46 then reads the information recorded in the wireless tag 58, that is, the information (part information) regarding the component BH packaged in the carrier tape CT of the roll body RT stored in the cassette 23, and transmits the read information to the feeder control unit 36.
[0063] Thus, in Embodiment 1, the reader 46 functions as a communication unit that reads information about the carrier tape component BH stored in the storage unit 55 from the wireless tag 58 provided on the cassette 23.
[0064] The flowchart in Figure 18 shows the flow of carrier tape CT feeding control performed by the main control unit 15 when cassette 23 is mounted on tape feeder 22. The main control unit 15 constantly monitors the detection signal sent from cassette detection unit 45 via feeder control unit 36 (step ST1). When the main control unit 15 detects from the detection signal from cassette detection unit 45 that cassette 23 has been mounted on cassette mounting unit 39, it activates the reader 46 to acquire component information from the wireless tag 58 attached to cassette 23, as well as information on the position (feeder address) of tape feeder 22 on feeder base 21c (step ST2).
[0065] In step ST2, the component verification unit 15c of the main control unit 15 obtains component information and a feeder address, and then performs component verification by comparing the component information and feeder address with the production program 15P obtained from the main control unit 15 of the component mounting device 1 (step ST3). Based on the results of the component verification, it is determined whether the correspondence between the component information and the feeder address is correct, that is, whether the cassette 23 containing the appropriate component BH has been mounted in the cassette mounting unit 39 (step ST4).
[0066] In this embodiment 1, the component verification unit 15c of the main unit control unit 15 functions as a determination unit that determines whether a cassette 23 containing the appropriate component BH has been installed in the cassette mounting unit 39, based on the information (component information) read by the reader 46 which acts as a communication unit.
[0067] In step ST4, if the component information verification result is OK (the component information and feeder address were correct), the main control unit 15 operates the introduction sprocket 33a to transport the carrier tape CT (step ST5) and then returns to step ST1. On the other hand, if the component verification result in step ST4 is NG (incorrect), the main control unit 15 does not transport the carrier tape CT, but instead notifies that the cassette 23 was incorrectly installed in the tape feeder 22 (step ST6) and then returns to step ST1.
[0068] In this embodiment, the tape transport unit 35 transports the carrier tape CT when the cassette detection unit 45 detects the cassette 23 and the component verification result is correct.
[0069] In the flowchart of Figure 18, the reader 46 reads part information from the wireless tag 58 attached to the cassette 23. However, if it is guaranteed by other methods or means that the part information of the carrier tape CT stored in the cassette 23 matches the part information described in the production program 15P, the processing by the part matching unit 15c can be omitted, and steps ST2, ST3, ST4, and ST6 in Figure 18 can be omitted. In this case, if the main control unit 15 detects in step ST1 that the cassette 23 has been mounted in the cassette mounting unit 39, it proceeds to step ST5, operates the introduction sprocket 33a to transport the carrier tape CT, and then returns to step ST1.
[0070] Figure 19 shows a modified example of the carrier tape CT loading control performed by the main control unit 15 as shown in the flowchart of Figure 18. In the flowchart shown in Figure 19, the trigger for the main control unit 15 to acquire component information and feeder address is not the detection signal output from the cassette detection unit 45 when the cassette 23 is mounted on the tape feeder 22, but rather the operation signal from the aforementioned operation switch 47 provided on the tape feeder 22.
[0071] In the flowchart of Figure 19, the main control unit 15 monitors whether the operator OP turns on the operation switch 47 instead of step ST1 in Figure 18 (step ST1A). When the operator OP loads the cassette 23 onto the tape feeder 22, they operate the operation switch 47 to notify the main control unit 15 that the cassette 23 has been loaded. When the main control unit 15 detects that the operator OP has operated (turned on) the operation switch 47, it activates the reader 46 to obtain part information from the wireless tag 58 attached to the cassette 23, and also obtains the feeder address via the connector 37 (step ST2), and performs part verification (step ST3), similar to the flowchart in Figure 18. If the part information verification result is OK (step ST4), the main control unit 15 activates the introduction sprocket 33a to transport the carrier tape CT (step ST5).
[0072] As shown in the flowchart of Figure 19, the carrier tape CT is transported when a predetermined operation is performed by the operator OP. This type of processing flow is effective when the tape feeder 22 does not have a cassette detection unit 45. When applying the flowchart of Figure 19 to a tape feeder 22 that has a cassette detection unit 45, the introduction sprocket 33a is activated in step ST5 only if there is a detection signal from the cassette detection unit 45, i.e., the cassette 23 is mounted on the tape feeder 22.
[0073] As described above, the tape feeder 22 in the component loading device 1 of Embodiment 1 includes a transport path 32 having an inlet 32a and an outlet 32b, and a tape transport section 35 that transports a carrier tape CT containing component BH along the transport path 32 when it is inserted into the inlet 32a, supplying the component BH to a component removal position 22K along the transport path 32. The cassette 23 includes a storage section 55 for storing the carrier tape CT and a tape tip holding section 60 for holding the leading ends (tape tip CTs) of the carrier tape CT stored in the storage section 55. The tape feeder 22 is also provided with a cassette mounting section 39 for mounting the cassette 23, allowing the cassette 23 to be mounted on the tape feeder 22.
[0074] Therefore, according to the component mounting device 1 in Embodiment 1, the component mounting device 1 can be made more compact. In addition, since the tape feeder 22 can be removed from the feeder base 21c and moved while the carrier tape CT is still inserted into the inlet 32a, handling of the tape feeder 22 and the cassette 23 (carrier tape CT inside the cassette 23) becomes easier.
[0075] Furthermore, in the flowchart shown in Figure 19, if it is guaranteed that the part information of the part BH packaged on the carrier tape CT stored in the cassette 23 matches the part information described in the production program 15P, by a method or means other than the method of reading the part information from the wireless tag 58 attached to the cassette 23 by the reader 46, then steps ST2, ST3, ST4, and ST6 in Figure 19 can be omitted.
[0076] (Embodiment 2) Next, Embodiment 2 of the present invention will be described. Figures 20 and 21 show the tape feeder 22A in Embodiment 2. The differences between the tape feeder 22A in Embodiment 2 and the tape feeder 22 in Embodiment 1 are that the exposure portion (reference numeral "38A") for peeling the cover tape TT from the carrier tape CT to expose the component BH consists of a pair of rollers (front roller 71a and rear roller 71b) provided inside the tape feeder 22A and arranged in the front-rear direction (Y direction), the frame 31 is provided with a cover tape discharge path 72 that extends rearward from the transport path 32 and opens to the rear surface of the tape feeder 22A, and the frame 31 is provided with an air ejection section 73.
[0077] In Embodiment 2, the front roller 71a and the rear roller 71b are positioned in contact with each other. The front roller 71a rotates clockwise in Figure 20, and the rear roller 71b rotates counterclockwise in Figure 20. One of the front roller 71a and the rear roller 71b rotates under the control of the feeder control unit 36, while the other rotates in the opposite direction in response. The air ejection unit 73 is operated under the control of the feeder control unit 36 and ejects air upward from between the front roller 71a and the rear roller 71b.
[0078] Figure 22 shows a cassette 23 used in Embodiment 2, which includes a cover tape storage section 80. The cover tape storage section 80 is detachably attached to the top of the cassette 23 and is attached to the cassette 23 so as to close (cover) the roll body opening 56 after the roll body RT has been stored in the storage section 55 through the roll body opening 56 of the cassette 23.
[0079] The inside of the cover tape storage section 80 is a hollow cover tape storage area 81. The front of the cover tape storage section 80 is provided with a collection opening 82 that connects to the cover tape storage area 81, and the rear is provided with a removal opening 83 that also connects to the cover tape storage area 81. The rear of the cover tape storage section 80 is provided with a door 84 that opens and closes the cover tape removal opening 83.
[0080] In Embodiment 2, the cover tape TT of the carrier tape CT pulled out from the roll body RT inside the cassette 23 is even longer at its leading edge than the tape protrusion CTt, and a cover tape extension TTt consisting only of the cover tape TT is formed at the end of the tape leading edge CTs (Figure 22). The procedure for mounting the cassette 23 to the cassette mounting section 39 of the tape feeder 22A is the same as in Embodiment 1. When the operator OP mounts the cassette 23 to the cassette mounting section 39, the collection port 82 of the cover tape storage section 80 is positioned opposite the rear end of the cover tape discharge path 72 which opens on the rear surface of the tape feeder 22A (Figure 23).
[0081] When the cassette 23 is mounted in the cassette mounting section 39, the tape protrusion CTt, together with the cover tape extension TTt, is located within the inlet 32a provided on the rear surface of the tape feeder 22A. Then, when the carrier tape CT is transported by the tape transport section 35, the tape leading edge CTs move along the transport path 32 with the cover tape extension TTt in front of them.
[0082] The carrier tape CT is transported by the tape transport unit 35, and when the leading edge of the cover tape extension TTt is positioned between the front roller 71a and the rear roller 71b, the feeder control unit 36 ejects air from the air ejection unit 73, blowing the cover tape extension TTt upward. As a result, the cover tape extension TTt is captured by the rotating front roller 71a and rear roller 71b and then sent into the cover tape discharge path 72. From the rear end of the cover tape discharge path 72, it proceeds to the opening of the cover tape storage unit 80 and is stored in the cover tape storage area 81 (Figure 23). Thus, in this embodiment 2, the cassette 23 is configured to include a cover tape storage unit 80 for storing the cover tape TT that has been peeled off at the exposed portion 38A.
[0083] In this way, the cover tape TT stored in the cover tape storage area 81 can be removed from the cover tape storage area 81 by opening the door 84 provided at the rear of the cover tape storage section 80 and opening the outlet 83. Furthermore, the cassette 23 can be moved together with the tape feeder 22A, and even when the tape feeder 22A is removed from the feeder base 21c before the carrier tape CT is completely used up, the tape feeder 22A, cassette 23, roll RT, and recovered cover tape TT can be handled as a single set, making it easy to use. Of course, the effects of Embodiment 1 can be obtained in Embodiment 2 as well.
[0084] As described above, in the component mounting device 1 of Embodiments 1 and 2, the cassette 23 for storing the carrier tape CT can be attached to the tape feeders 22 and 22A, making the component mounting device 1 more compact. This reduces costs, and the tape feeders 22 and 22A can be removed from the feeder base 21c and moved while the carrier tape CT is still inserted into the inlet 32a, making it easier to handle the tape feeders 22 and 22A and the cassette 23 (carrier tape CT inside the cassette 23).
[0085] While embodiments of the present invention have been described above, the present invention is not limited to those described above, and various modifications are possible. For example, the configuration in which the cassette detection unit 45 detects the insertion of the cassette 23 as shown in the above embodiment, and the configuration in which the reader 46 reads the wireless tag 58 attached to the cassette 23 to acquire component information are just examples, and the insertion of the cassette 23 and the acquisition of component information may be done by other configurations. Furthermore, the shape of the tape feeder 22 and the shape of the cassette 23 are not limited to those shown in the embodiment, and can be changed within the range in which the effects of the invention can be obtained. In addition, although the component matching unit 15c has been described as a function of the main unit control unit 15, it may be provided in a server or the like that can communicate with the main unit control unit 15.
