Mode for Carrying Out the Invention

[0009] (Embodiment 1) Figure 1 shows a component mounting device 1 equipped with a tape feeder as a component supply device in Embodiment 1 of the present invention. The component mounting device 1 is a device for mounting components BH on a substrate KB and is equipped with a substrate transport unit 12 on a base 11. The substrate transport unit 12 transports the substrate KB horizontally and positions it at a predetermined working position. For the sake of explanation, the transport direction of the substrate KB by the substrate transport unit 12 will be referred to as the X direction, the horizontal direction perpendicular to the X direction as the Y direction, and the vertical direction as the Z direction. Furthermore, within the Y direction, the direction toward the center of the base 11 will be referred to as "forward," and the direction toward the opposite side will be referred to as "rear."

[0010] A mounting head 13 is provided above the base 11. The mounting head 13 is moved horizontally by a head movement mechanism (not shown). The mounting head 13 is equipped with a plurality of component holding nozzles 14 extending downward.

[0011] In Figure 1, a trolley 15 is connected to the Y-direction end of the base 11. The trolley 15 is equipped with a feeder base 21 and a reel holding section 22. Multiple tape feeders 16 are mounted on the feeder base 21, arranged in the X-direction.

[0012] In Figures 2(a) and 2(b), the feeder base 21 has a block-shaped base portion 31 and a wall portion 32 provided at the front of the base portion 31 and extending upward. The upper surface of the base portion 31 is a feeder support portion 33, and the rear surface of the base portion 31 is a feeder connection surface 34.

[0013] The base portion 31 is provided with mounting slots 35 for mounting tape feeders 16, arranged in the X direction. As shown in Figure 2(a), one mounting slot 35 consists of a pair of feeder guides 41 arranged in the X direction on the feeder support portion 33, two upper and lower positioning holes 42 which are through holes penetrating the wall portion 32 in the thickness direction (Y direction), a mounting hole 44 provided on the feeder connection surface 34, an electrical socket 45, and an air socket 46. Thus, in Embodiment 1, the feeder base 21 has multiple mounting slots 35 arranged in the X direction.

[0014] The feeder guide 41 consists of rail-shaped members arranged laterally (X-direction, which intersects the carrier tape transport direction in the horizontal plane) and extending in the front-to-back direction (Y-direction). Two upper and lower positioning holes 42 are provided aligned in the Z-direction. The mounting hole 44, electrical socket 45, and air socket 46 are aligned in the Z-direction, with the mounting hole 44 located above the electrical socket 45. The air socket 46 is located between the mounting hole 44 and the electrical socket 45.

[0015] The reel holding unit 22 rotatably holds the reel RL around which the carrier tape CT, transported by the tape feeder 16, is wound. As shown in Figures 3(a) and (b), the carrier tape CT is provided with a large number of component storage pockets PK arranged in a row, and a large number of feed holes KH are provided in a row parallel to the row of component storage pockets PK.

[0016] In Figures 3(a) and 3(b), one component BH is stored in each component storage pocket PK, and a cover tape TT is attached to the upper surface of the carrier tape CT, covering the component storage pocket PK. In other words, the component BH is stored in the carrier tape CT covered by the cover tape TT.

[0017] As shown in Figures 3(a) and (b) or 4(a) and (b), the cover tape TT has a leading portion SD that protrudes from the leading edge ST of the carrier tape CT. The leading portion SD may be in the form of the leading edge of the cover tape TT protruding from the leading edge ST of the carrier tape CT, as shown in Figures 3(a) and (b), or it may be in the form of a part of the auxiliary tape HJ attached to the cover tape TT protruding from the leading edge ST of the carrier tape CT, as shown in Figures 4(a) and (b).

[0018] In the configuration where the tip of the cover tape TT protrudes from the tip ST of the carrier tape CT, the leading portion SD consists of a part of the cover tape TT (a portion of length L) that protrudes from the tip ST of the carrier tape CT (Figure 3(a)). In the configuration using an auxiliary tape HJ, the leading portion SD consists of a part of the auxiliary tape HJ (a portion of length L) that protrudes from the tip ST of the carrier tape CT (Figure 4(b)).

[0019] In Figures 5(a), (b) and 6, the tape feeder 16 includes a main body 51 that is detachably mounted in a mounting slot 35 of the feeder base 21. The front end of the main body 51 is provided with two positioning pins 52 that protrude forward.

[0020] In Figures 5(a), (b) and 6, a downward extension 53 is formed at the rear of the main body 51 of the tape feeder 16. On the front side of the downward extension 53, a fixed portion 54, a connector 55, and an air connection portion 56 are provided, each protruding forward.

[0021] When the tape feeder 16 is installed in the mounting slot 35, the engaging portion 51K (Figure 6) located at the bottom of the main body 51 is inserted between the feeder guides 41 that make up the mounting slot 35 (Figure 2(a) → Figure 2(b)). As a result, the two positioning pins 52 are inserted into the two upper and lower positioning holes 42, and the fixed portion 54 is fitted into the mounting hole 44. In addition, the connector 55 is connected to the electrical socket 45, and the air connection portion 56 is connected to the air socket 46.

[0022] When the fixed part 54 is fitted into the mounting hole 44, the fixed part 54 connects to a fixing part (not shown) provided inside the base part 31, and the tape feeder 16 is fixed to the base part 31. When the connector 55 is connected to the electrical socket 45, the tape feeder 16 is electrically and signal-transmittingly connected to the base part 31. When the air connection part 56 is connected to the air socket 46, it becomes possible to supply air from the base 11 side to the tape feeder 16 side through the base part 31.

[0023] In Figure 6, a transport path 61 is provided inside the main body 51 for transporting the carrier tape CT. The transport path 61 has a carrier tape inlet 61A at the rear end of the main body 51 and a carrier tape outlet 61B at the front end of the main body 51. The upper surface of the transport path 61 is a transport surface 61M (see Figure 8) for supporting and transporting the lower surface of the carrier tape CT. In other words, in Embodiment 1, the transport path 61 has a transport surface 61M that supports the carrier tape CT from below.

[0024] In Figure 6, a carrier tape transport unit 62 for transporting the carrier tape CT is provided in the upper front part of the main body 51. The carrier tape transport unit 62 consists of three sprockets (introduction sprocket 62A, positioning sprocket 62B, and discharge sprocket 62C) arranged from rear to front, and a sprocket drive motor 62D.

[0025] In Figure 6, multiple feed pins 62P are provided on the outer circumference of each of the introduction sprocket 62A, positioning sprocket 62B, and discharge sprocket 62C. These three sprockets are rotated in the same direction by a sprocket drive motor 62D via a gear mechanism (not shown). The direction in which the three sprockets rotate is the direction in which the feed pin 62P located at the highest position on each sprocket moves forward. The operation of the sprocket drive motor 62D is controlled by a control unit 63 (Figure 6) located within the main body 51.

[0026] The carrier tape CT is pulled out from the reel RL, and its leading end (the side where the aforementioned leading section SD is formed) is inserted into the transport path 61 through the carrier tape inlet 61A. The carrier tape CT inserted into the transport path 61 is transported forward (downstream) by the three sprockets (inlet sprocket 62A, positioning sprocket 62B, and discharge sprocket 62C) which are rotationally driven by the sprocket drive motor 62D, i.e., by the carrier tape transport section 62. At this time, the carrier tape CT is passed in the order of inlet sprocket 62A, positioning sprocket 62B, and discharge sprocket 62C.

[0027] The carrier tape CT inserted through the carrier tape inlet 61A is transported downstream, i.e., toward the carrier tape outlet 61B, by the carrier tape transport unit 62. As the carrier tape CT is transported downstream, the cover tape TT is peeled off before it passes through the parts removal opening 16K located on the front upper part of the main body 51. At the point when it passes through the parts removal opening 16K, the parts BH that were stored in the carrier tape CT covered by the cover tape TT are exposed.

[0028] The component removal opening 16K is located between the positioning sprocket 62B and the discharge sprocket 62C, and exposed components BH are intermittently positioned one after another at the component removal position 16T set inside the component removal opening 16K. This allows the mounting head 13 to use the component holding nozzle 14 to suction and hold the components BH located at the component removal opening 16K (component removal position 16T) and remove (pick up) them from the tape feeder 16. In this way, the carrier tape transport unit 62 transports the carrier tape CT along the transport path 61 with the lead section SD of the cover tape TT leading, thereby positioning the components BH at the component removal position 16T.

[0029] In Figure 6, the aforementioned air connection section 56, provided in the downward extension section 53 of the main body 51, is connected to an air ejection section 65 provided in the front upper part of the main body 51 via an air pipe 64 provided within the downward extension section 53. An air ejection control valve 66, provided within the downward extension section 53, is interposed in the air pipe 64.

[0030] When the tape feeder 16 is mounted on the feeder base 21, the air connection part 56 is connected to the air socket 46 on the feeder base 21 side. With the air connection part 56 connected to the air socket 46, the control unit 63 controls the air ejection control valve 66, which allows air supplied from the feeder base 21 side through the air pipe 64 to be ejected from the air ejection part 65.

[0031] In Figure 6, a tape cover 70, as shown in Figure 7, is provided on the front upper part of the main body 51. More specifically, as shown in Figures 8 and 9, it is provided to cover from above the portion of the transport path 61 located between the positioning sprocket 62B and the discharge sprocket 62C. In Embodiment 1, the tape cover 70 is composed of a single plate-like member and is detachably attached to the main body 51.

[0032] Figure 10 shows the tape cover 70 attached to the main body 51. As can be seen from Figure 10, the main body 51 of the tape feeder 16 has two carrier tape support sections 51S that extend outwards along the YZ plane and face each other in the X direction. The upper edges of the carrier tape support sections 51S form the transport surface 61M.

[0033] As shown in Figure 10, the tape cover 70 is provided on the front upper part of the two carrier tape support sections 51S, so as to cover a portion of the upper edges (i.e., the transport surface 61M) of the two carrier tape support sections 51S from above. As described above, the transport surface 61M consists of the upper edges of the two carrier tape support sections 51S, and both ends of the carrier tape CT are supported from below by the upper edges of the two carrier tape support sections 51S. Therefore, not only carrier tapes without downward protruding portions (so-called paper tape type) but also embossed types with downward protruding embossed portions can be used for the carrier tape CT.

[0034] In Figures 7 and 10, the tape cover 70 comprises a first tape retaining portion 71 that constitutes its central part, a second tape retaining portion 72 that constitutes the portion upstream of the first tape retaining portion 71, and a third tape retaining portion 73 that constitutes the portion downstream of the first tape retaining portion 71. The first tape retaining portion 71 and the second tape retaining portion 72 are connected by a connecting portion 74. A cover tape passage 75 is formed to the side of the connecting portion 74 (in the width direction of the tape cover 70, i.e., the X direction), consisting of the gap between the first tape retaining portion 71 and the second tape retaining portion 72. The aforementioned parts removal opening 16K is formed in the third tape retaining portion 73 (Figure 7).

[0035] In this embodiment 1, the tape cover 70 covers the upper surface of the carrier tape CT transported by the carrier tape transport unit 62 and has a cover tape passage 75 consisting of a parts removal opening 16K formed at the parts removal position 16T and a gap formed at a position upstream from the parts removal opening 16K.

[0036] In Figure 7, a protruding piece 71H is formed at the upstream end of the first tape holding portion 71, and the edge of this protruding piece 71H (i.e., the upstream edge of the first tape holding portion 71) serves as a stopper 76. As will be described later, the stopper 76 functions as part of a guide portion 140 (Figure 8) that blocks the progress of the lead portion SD of the cover tape TT of the carrier tape CT transported by the carrier tape transport portion 62, and guides the lead portion SD upward (towards the upper surface of the tape cover 70) from the cover tape passage 75.

[0037] As described above, the second tape retaining portion 72 is connected to the upstream side of the first tape retaining portion 71 by a connecting portion 74. The downstream end of the second tape retaining portion 72 has a straight shape extending in the X direction and is positioned upstream of the stopper 76, which is the upstream edge of the first tape retaining portion 71, with a predetermined gap (cover tape passage 75) between it and the stopper 76.

[0038] In Figure 11, the downstream portion of the second tape-holding section 72 is a contact section 77 that extends parallel to the conveying surface 61M above the conveying surface 61M. The portion upstream of the contact section 77 is an inclined section 78 whose height from the conveying surface 61M gradually increases towards the upstream side. The lower surface of the inclined section 78 is a tapered surface 78M in which the distance between it and the conveying surface 61M narrows from upstream to downstream.

[0039] In Figure 11, when the carrier tape CT is not inserted into the transport path 61, the lower surface of the second tape retainer 72 is not in contact with the transport surface 61M, and a gap of size GP is formed between the lower surface of the second tape retainer 72 and the transport surface 61M. The size of this gap GP is larger than the thickness of the cover tape TT, but smaller than the thickness of the carrier tape CT.

[0040] In Figure 7, both ends of the third tape retaining portion 73 in the width direction (X direction) are bent portions 79 that are folded downward. Because the third tape retaining portion 73 has bent portions 79 formed at both ends in the width direction in this way, its bending rigidity in the vertical direction is increased and it is less prone to bending, thereby allowing the carrier tape CT near the parts removal opening 16K to be firmly pressed against the transport surface 61M. On the other hand, the first tape retaining portion 71 connected to the upstream side of the third tape retaining portion 73 and the second tape retaining portion 72 connected further upstream via a connecting portion 74 do not have bent portions like the third tape retaining portion 73, and therefore can easily bend in the vertical direction.

[0041] In Figures 7 and 10, the tape cover 70 is provided with a sprocket avoidance hole 80 extending in the Y direction. The sprocket avoidance hole 80 is provided to prevent interference between the feed pin 62P of the positioning sprocket 62B and the tape cover 70.

[0042] In Figures 8 and 9, the tape cover 70 is biased (pressed) from above by three biasing parts (front pressing part 81, middle pressing part 82, and rear pressing part 83) provided on the front upper part of the main body 51. Here, the front pressing part 81 has the function of pressing the portion of the tape cover 70 downstream of the parts removal opening 16K against the carrier tape CT on the transport surface 61M. The middle pressing part 82 has the function of pressing the portion of the tape cover 70 between the parts removal opening 16K and the cover tape passage 75 against the carrier tape CT on the transport surface 61M. The rear pressing part 83 has the function of pressing the portion of the tape cover 70 upstream of the cover tape passage 75 against the carrier tape CT on the transport surface 61M.

[0043] In this embodiment 1, the entire tape cover 70 is biased toward the transport surface 61M in a balanced manner by the three biasing parts (front pressing part 81, middle pressing part 82, and rear pressing part 83). As a result, the carrier tape CT, which is moving along the transport path 61 in the front upper region of the main body 51 including the part removal position 16T, moves while maintaining a state of being pressed against the transport surface 61M with an appropriate pressing force. Therefore, the positioning of the part BH at the part removal position 16T can be accurately performed, and consequently, the occurrence of pickup errors of the part BH by the mounting head 13 can be prevented.

[0044] In Figures 8 and 9, the front retaining portion 81 comprises a retaining plate 81a as a first swinging lever, a base portion 81b, and a first coil spring 81c. The retaining plate 81a extends in the Y direction from the front upper part of the main body portion 51 (more specifically, the area including above the discharge sprocket 62C and near the carrier tape discharge port 61B), and the base portion 81b provided at the downstream end is supported by the main body portion 51 by a support pin 81d extending in the X direction. The first coil spring 81c is provided between the base portion 81b and the main body portion 51 and biases the base portion 81b in a direction that pushes it upward relative to the main body portion 51.

[0045] As shown in Figures 8 and 9, the retaining plate 81a is in contact with the vicinity of the downstream end of the tape cover 70 from above, with its upstream end abutting against it. As a result, the downstream portion of the tape cover 70 (third tape retaining portion 73) is biased downward (towards the transport surface 61M) by the first coil spring 81c via the retaining plate 81a (pressed against it).

[0046] As described above, in Embodiment 1, the front pressing portion 81 includes a pressing plate 81a as a first swing lever that swings about a horizontal axis (support pin 81d) perpendicular to the transport direction of the carrier tape CT, and a first coil spring 81c that biases one end of the pressing plate 81a to the upper surface of the tape cover 70. When the carrier tape CT inserted into the transport path 61 has not yet reached below the tape cover 70 (referred to as the "initial state"; Figure 8), the third tape pressing portion 73 has its lower surface in contact with the transport surface 61M.

[0047] In Figures 8 and 9, the central retaining section 82 comprises a spring retaining section 82a, a torsion spring 82b, and a retaining roller 82c. The spring retaining section 82a consists of an axial member extending in the X direction, supported at both ends by a side cover 51P provided on the side surface (YZ plane) of the main body 51, straddling the transport path 61. This side cover 51P constitutes the main body 51.

[0048] In Figures 8, 9, and 12, the torsion spring 82b is held in the spring retaining part 82a by its coiled portion being inserted into the spring retaining part 82a (in the X direction). Of the upstream extension and downstream extension, the upstream extension is locked to a pin fixed to the side cover 51P. The retaining roller 82c extends in the X direction, and both ends are supported by the two side covers 51P in a manner that allows it to move up and down. The retaining roller 82c is rotatable about an axis along the X direction.

[0049] The pressing roller 82c is located in the middle of the tape cover 70 (the portion sandwiched between the parts removal opening 16K and the cover tape passage 75) and is biased downward by the downstream extension of the torsion spring 82b. As a result, the middle portion of the tape cover 70 (first tape pressing portion 71) is biased downward (towards the conveying surface 61M) by the torsion spring 82b via the pressing roller 82c (pressing force F1 shown in Figure 12).

[0050] In this embodiment 1, the middle pressing section 82 includes a pressing roller 82c as a roller pin that can rotate around a horizontal axis (X-axis) intersecting the transport direction of the carrier tape CT, and a torsion spring 82b as an elastic body that biases the pressing roller 82c to the upper surface of the tape cover 70. In the initial state when the carrier tape CT inserted into the transport path 61 has not yet reached below the tape cover 70, the lower surface of the second tape pressing section 72 is in contact with the transport surface 61M (Figure 12).

[0051] In Figures 8 and 9, the rear retaining portion 83 includes a rear retaining lever 91 as a second oscillating lever and a second coil spring 92. The rear retaining lever 91 extends in the Y direction from the front upper part of the main body portion 51 (more specifically, the area above the introduction sprocket 62A). As shown in Figure 12, the rear retaining lever 91 is supported in the Y direction by a lever oscillating shaft 93 that extends in the X direction, and has an upstream extension portion 91a extending upstream from the lever oscillating shaft 93 and a downstream extension portion 91b extending downstream.

[0052] In Figure 12, the downstream extension 91b extends with its tip bent downward, and the tip of this bent extension, the retaining lever tip 91c, is located above the second tape retaining portion 72. The second coil spring 92 biases the upstream extension 91a of the rear retaining lever 91 upward, that is, away from the conveying surface 61M. Therefore, the lever tip 91c of the rear retaining lever 91 is biased downward, that is, toward the conveying surface 61M.

[0053] The range of rotation of the rear-pressing lever 91 is restricted by a pin 94 fixed to the main body 51. Therefore, in the initial state when the carrier tape CT has not yet reached below the contact portion 77 of the second tape-pressing portion 72, the lever tip 91c is located at a distance smaller than the thickness of the carrier tape CT from the upper surface of the upstream portion of the tape cover 70 (second tape-pressing portion 72), and the lever tip 91c is not in contact with the second tape-pressing portion 72. When the carrier tape CT reaches below the contact portion 77 of the second tape-pressing portion 72 and the second tape-pressing portion 72 is lifted by the carrier tape CT, the second tape-pressing portion 72 comes into contact with the lever tip 91c. As a result, the second tape-pressing portion 72 is biased (pressed) downward (towards the carrier tape CT) by the second coil spring 92 via the rear-pressing lever 91 (see also Figure 24).

[0054] In this embodiment 1, the rear pressing portion 83 includes a rear pressing lever 91 as a second swinging lever that swings about a horizontal axis (lever swing axis 93) perpendicular to the transport direction of the carrier tape CT, and a second coil spring 92 that biases one end of the rear pressing lever 91 to the upper surface of the tape cover 70. Furthermore, together with the middle pressing portion 82, the rear pressing portion 83 is configured to press down on the upstream region (first tape pressing portion 71 and second tape pressing portion 72) located upstream of the third tape pressing portion 73, which is the downstream region in the tape cover 70 where the parts removal opening 16K is formed.

[0055] In Figures 8, 9, and 12, a cover tape pull-in section 101 is provided upstream of the component removal position 16T. More specifically, it is located above the tape cover 70 within the main body 51. The cover tape pull-in section 101 has the function of pulling the cover tape TT, which has been peeled off from the carrier tape CT, upward.

[0056] In Figures 11 and 12, the cover tape pull-in section 101 consists of a drive roller 101a and a driven roller 101b, which has a smaller diameter than the drive roller 101a and is located downstream of the drive roller 101a. The drive roller 101a and the driven roller 101b are in contact, and when the drive roller 101a rotates counterclockwise in Figure 11, the driven roller 101b is rotated clockwise by the drive roller 101a. The drive roller 101a is driven by a transmission gear mechanism (not shown) that transmits power from the sprocket drive motor 62D. Therefore, the drive roller 101a is driven at the same timing as the carrier tape transport section 62.

[0057] In Figures 8, 9, and 12, a cover tape discharge channel 102 is provided upstream of the cover tape retraction section 101 within the main body 51. The cover tape TT retracted by the cover tape retraction section 101 is discharged into the cover tape discharge channel 102.

[0058] In Figures 8, 9, and 12, a straightening section 103 is provided at the upstream position of the tape cover 70 within the main body 51 (see also Figure 11). The straightening section 103 has the function of straightening the leading section SD of the cover tape TT of the carrier tape CT inserted into the transport path 61 from the carrier tape inlet 61A if it is bent upwards or downwards.

[0059] As shown in Figures 10 and 11, the straightening section 103 has a oscillating member 111 and a recess 112. The straightening section 103 is located upstream of the part removal position 16T and has the function of straightening the leading portion SD of the cover tape TT so that it is directed downstream from the leading edge ST of the carrier tape CT as the carrier tape CT moves downstream after being sent downstream by the carrier tape transport section 62 and then returned upstream.

[0060] In Figure 11, the oscillating member 111 has a base portion 111a supported by the lever oscillating shaft 93, which is the oscillating axis of the rear-holding lever 91, and an extension portion 111b that extends downstream from the base portion 111a and whose tip is curved downward. The oscillating member 111 attempts to oscillate due to its own weight in a direction in which the tip of the extension portion 111b is pointed downward (clockwise in Figure 11), but this oscillation is restricted by contact with an oscillating restricting member (not shown).

[0061] In the state where the oscillation of the oscillating member 111 due to its own weight is restricted (as shown in Figure 11, referred to as the "oscillating restricted state"), the lower end edge of the extension portion 111b (oscillating member edge 111c) is positioned at a certain distance (size gp) upward from the conveying surface 61M. The size gp of this certain distance is greater than the thickness of the cover tape TT and smaller than the sum of the thicknesses of the carrier tape CT and the cover tape TT. In Embodiment 1, the oscillating member edge 111c and the conveying surface 61M are separated by a distance gp, but if there is no risk of buckling of the leading portion SD of the cover tape TT, the oscillating member edge 111c may be in contact with the conveying surface 61M.

[0062] When the swinging member 111's edge 111c is pushed up by the carrier tape CT from the swinging restricted state shown in Figure 11, the swinging member 111 swings in the direction that lifts the swinging member edge 111c (counterclockwise direction in Figure 11). It then maintains the state in which the swinging member edge 111c is in contact with the upper surface of the carrier tape CT.

[0063] In Figures 10 and 11, the recess 112 has a curved surface 112M formed by a part of the transport surface 61M being recessed downwards. As mentioned above, the transport surface 61M is composed of the upper edges of two carrier tape support parts 51S that are positioned opposite each other in the X direction, so the recess 112 (curved surface 112M) is also formed on the upper edges of these two carrier tape support parts 51S (Figure 10). Of the upstream and downstream edges of the recess 112, the upstream edge, the recess edge 112E, is located downstream of the oscillating member edge 111c (Figure 11).

[0064] Next, the operation of supplying parts BH by the tape feeder 16 will be described. When the tape feeder 16 transports the carrier tape CT and supplies parts BH to the parts pick-up position 16T, the operator first ensures that the lead part SD is extended from the tip of the carrier tape CT according to the procedure described above, and then manually inserts the tip ST of the carrier tape CT into the carrier tape inlet 61A. Then, the operator pushes the carrier tape CT downstream until the feed hole KH of the tip ST of the carrier tape CT engages with the feed pin 62P of the introduction sprocket 62A.

[0065] When the carrier tape CT is inserted through the carrier tape inlet 61A, the feed hole KH near the leading edge ST of the carrier tape CT engages with the feed pin 62P of the introduction sprocket 62A, which is detected by a sensor (not shown). When the sensor detects that the feed hole KH of the carrier tape CT has engaged with the feed pin 62P of the introduction sprocket 62A, the control unit 63 activates the sprocket drive motor 62D to rotate the three sprockets (introduction sprocket 62A, positioning sprocket 62B, and discharge sprocket 62C). Alternatively, an operator inserts the carrier tape CT through the carrier tape inlet 61A, engaging the feed hole KH with the feed pin 62P of the introduction sprocket 62A, and operates the operation switch of the tape feeder 16 to activate the sprocket drive motor 62D and rotate the three sprockets. This starts the transport of the carrier tape CT by the carrier tape transport unit 62, and the carrier tape CT moves downstream on the transport surface 61M. At this point, the tape cover 70 is still in its initial state (Figure 12).

[0066] As the leading edge ST of the carrier tape CT moves downstream on the transport surface 61M, as shown in Figure 13, it passes below the oscillating member edge 111c, which is waiting at a position separated from the transport surface 61M, and then passes the recessed edge 112E. When the leading edge ST of the carrier tape CT reaches a position P1 located a predetermined distance D1 (Figure 13) downstream from the position S1 of the recessed edge 112E, the control unit 63 temporarily stops the operation of the sprocket drive motor 62D (i.e., temporarily stops the movement of the carrier tape CT).

[0067] Here, the predetermined distance D1 is a distance that exceeds the length L of the lead portion SD of the cover tape TT (D1 > L). Therefore, when the rotation of the sprocket drive motor 62D stops (and thus the movement of the carrier tape CT stops), if the lead portion SD of the cover tape TT is bent either above or below the carrier tape CT, the lead portion tip SS of the lead portion SD of the cover tape TT (see also Figures 3(a) and 4(b)) is located downstream of both the oscillating member edge 111c and the recessed edge 112E (Figure 13). If the lead portion SD of the cover tape TT is not bent either above or below the carrier tape CT, the lead portion tip SS of the cover tape TT enters the space between the transport surface 61M and the lower surface of the contact portion 77 of the second tape presser 72 (the space of the gap of size GP mentioned above).

[0068] After temporarily suspending the movement of the carrier tape CT as described above, the control unit 63 rotates the sprocket drive motor 62D in the reverse direction. This causes the carrier tape CT to move upstream (i.e., backward). If the leading portion SD of the cover tape TT is bent upward as shown in Figure 13 when the carrier tape CT begins to move backward, the tip SS of the leading portion TT of the cover tape TT will come into contact with the extended portion 111b or the edge 111c of the oscillating member 111 from the downstream side (Figures 14 and 15).

[0069] When the control unit 63 starts the backward movement of the carrier tape CT, when the leading end ST of the carrier tape CT reaches the position P2 that has retreated a predetermined distance D2 downstream from the position S2 of the swing member edge 111c, the operation of the sprocket drive motor 62D is stopped (FIG. 16). Here, by setting the predetermined distance D2 to be smaller than the length L of the leading portion SD of the cover tape TT and larger than half of the length of the leading portion SD (0.5L < D2 < L), when the backward movement of the carrier tape CT is stopped, the leading end ST of the carrier tape CT is in a state of being located upstream of the swing member edge 111c. In this state, the upward bending state of the leading portion SD of the cover tape TT is eliminated, and it extends substantially straight toward the downstream side, that is, the upward bending of the leading portion SD of the cover tape TT is corrected (FIG. 16).

[0070] As described above, in the first embodiment, after the leading end ST of the carrier tape CT advances a predetermined distance D1 (to a downstream position farther from the concave edge 112E than the length L of the leading portion SD from the concave edge ************) downstream of the correction edge (here, the concave edge 112E), the carrier tape CT is moved (retreated) to an upstream position where its leading end ST is separated from the correction edge (swing member edge 111c) by a predetermined distance D2 that is smaller than the length L of the leading portion SD and larger than half of the length L of the leading portion SD. A series of operations (hereinafter referred to as the "switchback operation") are performed. By performing this switchback operation, even when the leading portion SD of the cover tape TT is in the upwardly bent state, this can be eliminated.

[0071] As described above, in the first embodiment, the correction unit 103 includes the swing member 111 that is disposed above the transport surface 61M and has the swing member edge 111c as the correction edge at the lower end. Further, the swing member edge 111c of the swing member 111 waits for the leading end of the carrier tape CT to advance from the upstream side at a position spaced upward from the transport surface 61M.

[0072] Furthermore, if the leading portion SD of the cover tape TT of the carrier tape CT inserted into the carrier tape inlet 61A is bent downwards, the tip SS of the leading portion of the cover tape TT will catch on the upstream edge (recess edge 112E) of the recess 112 during the switchback operation described above (Figure 17). Therefore, when the switchback operation is completed and the tip ST of the carrier tape CT is positioned upstream of the oscillating member edge 111c (Figure 16), the downward bend of the leading portion SD of the cover tape TT is eliminated, and it extends almost straight toward the downstream side, that is, the downward bend of the leading portion SD of the cover tape TT is corrected (Figure 16).

[0073] In this embodiment 1, the recess 112 formed on the transport surface and the recess edge 112E on the upstream side of the recess 112 become part of the straightening portion 103.

[0074] When the upward or downward bend of the cover tape TT is corrected by the switchback operation of the carrier tape CT described above (Figure 16), the control unit 63 activates the sprocket drive motor 62D to rotate the three sprockets in the direction in which the carrier tape CT moves downstream. As a result, the leading edge ST of the carrier tape CT passes the oscillating member edge 111c downstream, and the leading edge SS of the cover tape TT, which is extended downstream, enters below the inclined portion 78 of the second tape presser portion 72 of the tape cover 70 (Figure 18). Furthermore, the leading edge SS of the cover tape TT enters the space between the second tape presser portion 72 and the transport surface 61M (a gap space of size GP) (Figure 19).

[0075] Here, if the leading portion SD of the cover tape TT, which has been straightened by the straightening portion 103 and extended downstream (or the leading portion SD of the cover tape TT, which was not bent upward or downward from the time it was inserted from the carrier tape inlet 61A), is slightly curved upward just before entering the space between the contact portion 77 of the second tape press portion 72 and the transport surface 61M (a gap space of size GP) (see the leading portion indicated by the symbol "SD1" in Figure 18), then the tip SS of the leading portion will proceed downstream following the tapered surface 78M of the second tape press portion 72. This prevents the leading portion SD of the cover tape TT, which has been straightened by the oscillating member edge 111c and the recessed edge 112E, from bending upward again. In this way, the lower surface (tapered surface 78M) of the inclined portion 78 of the second tape press portion 72 acts as an upward bending prevention surface that prevents the cover tape TT from bending upward.

[0076] Furthermore, if the leading portion SD of the cover tape TT is slightly curved downwards just before entering the space between the second tape holding portion 72 and the transport surface 61M (see the leading portion indicated by the symbol "SD2" in Figure 18), the tip SS of the leading portion will follow the curved surface 112M of the recess 112 and proceed downstream. This prevents the leading portion SD of the cover tape TT, which has been straightened by the oscillating member edge 111c and the recess edge 112E, from bending downwards again. In this way, the surface of the recess 112 (curved surface 112M) serves as a downward bending prevention surface that prevents the cover tape TT from bending downwards, which would otherwise result in the cover tape TT being folded below the carrier tape CT.

[0077] The leading portion SD of the cover tape TT, having entered the space (gap space of size GP) between the contact portion 77 of the second tape holding portion 72 and the transport surface 61M, is blocked by the stopper 76 which is in contact with the transport surface 61M, preventing the leading portion SD from advancing further downstream (Figure 20). Then, as the carrier tape CT is transported further downstream, the leading tip SS of the cover tape TT passes upward through the cover tape passage 75 and protrudes above the second tape holding portion 72 (i.e., the tape cover 70) (Figure 21).

[0078] Thus, the stopper 76 provided by the first tape holding section 71 has the function of preventing the leading edge SS of the cover tape TT advancing from the upstream side from entering between the first tape holding section 71 and the transport surface 61M when the first tape holding section 71 is in contact with the transport surface 61M. In Embodiment 1, the first tape holding section 71 includes a stopper 76 located downstream of the second tape holding section 72 and positioned on the transport surface 61M, and serves as a carrier tape holding section that holds the carrier tape CT on the transport surface 61M.

[0079] As described above, the control unit 63 controls the air ejection control valve 66 at the timing when the leading edge SS of the cover tape TT reaches the cover tape passage 75 of the tape cover 70 (or just before that timing), causing air 107 to be ejected upward from the air ejection unit 65 (Figure 21). The air ejection unit 65 is positioned so that the ejected air 107 passes through the cover tape passage 75 from below.

[0080] When the leading edge SS of the cover tape TT reaches the cover tape passage 75, air 107 is ejected from the air ejection port 65. The leading edge SS of the cover tape TT is guided by the flow of air 107 ejected from the air ejection port 65, passes upward through the cover tape passage 75, and protrudes above the tape cover 70. Then, as the carrier tape CT moves downstream, it moves upward and reaches the space between the drive roller 101a and the driven roller 101b that constitute the cover tape retraction section 101 (Figure 22).

[0081] Thus, in Embodiment 1, the air ejection section 65 is an auxiliary section that utilizes the flow of air (i.e., gas) to assist in the movement of the leading section SD toward the cover tape retraction section 101. Furthermore, in Embodiment 1, the first tape pressing section 71, which includes the stopper 76 as a carrier tape pressing section, and the air ejection section 65, which is an auxiliary section, are both guide sections 140 that lead the leading section SD toward the cover tape retraction section 101.

[0082] The leading edge SS of the cover tape TT, which has reached between the drive roller 101a and the driven roller 101b, is captured by the cover tape retraction section 101 (by the opposing rotation of the drive roller 101a and the driven roller 101b) and pulled upward (Figure 23).

[0083] As described above, once the leading portion SD of the cover tape TT passes upward through the cover tape passage 75, the tip ST of the carrier tape CT comes into contact with the tapered surface 78M of the second tape retaining portion 72 (Figure 21). As the carrier tape CT, with its tip ST in contact with the tapered surface 78M, continues to move downstream, the second tape retaining portion 72 is pushed up by the carrier tape CT (Figure 21 → Figure 22).

[0084] The second tape retainer 72, pushed up by the carrier tape CT, pulls the first tape retainer 71 upward via the connecting portion 74. As a result, a gap of interval G (Figure 22) is formed between the first tape retainer 71 and the transport surface 61M, allowing the carrier tape CT to move forward, and the stopper 76, which is the upstream edge of the first tape retainer 71, also rises from the transport surface 61M. Once a gap of interval G is formed between the first tape retainer 71 and the transport surface 61M, the carrier tape CT moves downstream within that gap (Figure 22 → Figure 23).

[0085] Thus, the second tape presser 72 is a contact displacement part that is displaced by contacting the carrier tape CT, and the connecting part 74 is a transmission part that transmits the displacement of the second tape presser 72 as a contact displacement part to the first tape presser 71, thereby displacing the stopper 76. The second tape presser 72 as a contact displacement part and the connecting part 74 as a transmission part form a height changing part 70T (Figure 7) that lifts the stopper 76 upward from the transport surface 61M.

[0086] As described above, when the second tape retaining portion 72 is pushed up by the carrier tape CT, the inclined portion 78 of the second tape retaining portion 72 comes into contact with the tip 91c of the retaining lever of the rear retaining portion 83 from below, pushing up the tip 91c of the retaining lever. As a result, the second coil spring 92 of the rear retaining portion 83 is compressed by the upstream extension 91a of the rear retaining lever 91, and in reaction force biases the upstream extension 91a upward. Therefore, the second tape retainer 72 (inclined portion 78) is biased downward by the second coil spring 92 via the rear retaining lever 91 (pressing force F2 shown in Figure 24).

[0087] In this embodiment 1, the rear pressing lever 91 is not in contact with the tape cover 70 when the carrier tape CT is not in the transport path 61, and when it comes into contact with the tape cover 70 (specifically the second tape pressing lever 72) which has been displaced upward by the carrier tape CT, it presses it downward.

[0088] As the carrier tape CT moves downstream through the gap formed between the lower surface of the first tape holding section 71 and the transport surface 61M, the cover tape TT that has passed through the cover tape passage 75 and extends upward is further pulled upward (into the cover tape discharge passage 102) by the cover tape pull-in section 101 (Figure 25).

[0089] In this embodiment 1, the cover tape pull-in section 101 pulls in the cover tape TT that has been peeled off from the carrier tape CT.

[0090] In Embodiment 1, the tape cover 70 and the cover tape pull-in section 101 constitute the cover tape peel-off section 120 (Figure 8) (see also Figures 6 and 11). Here, the cover tape peel-off section 120 is a functional section located downstream of the straightening section 103 and upstream of the parts removal position 16T, which captures and pulls in the leading section SD of the cover tape TT that extends downstream from the tip ST of the carrier tape CT, thereby peeling the cover tape TT from the upper surface of the carrier tape CT that is sent downstream by the carrier tape transport section 62.

[0091] The carrier tape CT, from which the cover tape TT has been peeled off by the cover tape peeling unit 120, is transported downstream along the transport path 61 by the carrier tape transport unit 62, and the first component storage pocket PK on the carrier tape CT is positioned at the component removal position 16T. This completes the positioning process of the carrier tape CT. The carrier tape transport unit 62 performs the operation (the positioning process of the carrier tape CT) from position P2 to positioning the first component storage pocket PK at the component removal position 16T without stopping.

[0092] During the positioning process of the carrier tape CT, the cover tape TT is peeled off by the cover tape peeling unit 120. Thereafter, as the mounting head 13 of the component mounting device 1 picks up and removes the component BH (pickup operation), the carrier tape transport unit 62 performs pitch feeding, and the component storage pockets PK are sequentially positioned at the component removal position 16T (carrier tape positioning operation).

[0093] In this embodiment 1, the tape feeder 16, as a parts supply device, peels off the cover tape TT having a leading portion SD that protrudes from the tip of the carrier tape CT from the carrier tape CT, exposing the parts BH that were stored in the carrier tape CT covered by the cover tape TT, and transports the exposed parts BH to the parts removal position 16T for supply to the parts mounting device 1.

[0094] When a component mounting device 1 having the tape feeder 16 configured as described above performs component mounting work to mount components BH onto a substrate KB, first, the substrate transport unit 12 carries in the substrate KB supplied from outside the component mounting device 1 and positions it at a predetermined work position. Once the substrate KB is positioned at the work position, each tape feeder 16 supplies components BH to the component removal opening 16K, and the mounting head 13 uses the component holding nozzle 14 to hold and remove the components BH from the component removal position 16T of the tape feeder 16. After removing the components BH from the component removal position 16T of the tape feeder 16, the mounting head 13 moves above the substrate KB and mounts the components BH at the designated target component mounting position on the substrate KB. Once all the components BH to be mounted on the substrate KB have been mounted, the substrate transport unit 12 transports the substrate KB to the outside of the component mounting device 1. This completes the component mounting work for one substrate KB.

[0095] As described above, in Embodiment 1, the tape feeder 16 transports the carrier tape CT along the transport path 61 with the lead portion SD of the cover tape TT in the lead position, and returns the carrier tape CT that has been sent downstream to the upstream position, thereby allowing the straightening unit 103 to straighten the bent state of the lead portion SD. Therefore, even if the lead portion SD of the cover tape TT is bent, it can be reliably captured by the cover tape pull-in unit 101.

[0096] Furthermore, the tape feeder 16 in Embodiment 1 is equipped with a guide section 140 that guides the lead section SD towards the cover tape retraction section 101, and the lead section SD of the cover tape TT is blocked and guided by a stopper 76. As a result, the lead section SD of the cover tape TT can be reliably guided to and captured by the cover tape retraction section 101. After the lead section SD of the cover tape TT is captured by the cover tape retraction section 101, the stopper 76 is lifted upward by the height change section 70T, so the carrier tape CT can proceed along the transport path 61 without being blocked by the stopper 76, and the transport of the carrier tape CT is not obstructed. The guide section 140 in the tape feeder 16 in Embodiment 1 includes a carrier tape pressing section (first tape pressing section 71) that presses the carrier tape CT on the transport surface 61M downstream of the contact displacement section (second tape pressing section 72).

[0097] Furthermore, in the tape feeder 16 of Embodiment 1, the tape cover 70, which has a component removal opening 16K and a cover tape passage 75, is held down by a front pressing part 81 in the portion downstream of the component removal opening 16K, by a middle pressing part 82 in the portion sandwiched between the component removal opening 16K and the cover tape passage 75, and by a rear pressing part 83 in the portion upstream of the cover tape passage 75, so that the entire tape cover 70 is pressed against the transport path 61 in an appropriate balance. As a result, the transport of the carrier tape CT in the region including the vicinity of the component removal position 16T can be performed stably, and the accuracy of component BH removal can be improved.

[0098] (Embodiment 2) Figure 26 shows a part of the tape feeder in Embodiment 2. The tape feeder in Embodiment 2 is the same as the tape feeder 16 in Embodiment 1, except that the straightening edge is only the straightening edge that faces the upper surface of the carrier tape CT (the oscillating member edge 111c in Embodiment 1).

[0099] Embodiment 2 differs from Embodiment 1 in that the straightening portion 103 does not have a recess 112. This configuration can be used when it is not possible for the leading portion SD of the cover tape TT of the carrier tape CT inserted from the carrier tape inlet 61A to bend downward, that is, when inserting the carrier tape CT from the carrier tape inlet 61A, the leading portion SD of the cover tape TT is bent upward in advance, that is, when the carrier tape CT is inserted into the carrier tape inlet 61A with the leading portion SD bent upward. In Embodiment 2 as well, the straightening portion 103 has a straightening edge, so the same effect as the tape feeder 16 in Embodiment 1 can be obtained.

[0100] (Embodiment 3) Figure 27 shows a part of the tape feeder in Embodiment 3. The tape feeder in Embodiment 3 is the same as the tape feeder 16 in Embodiment 1, except that the straightening edge is only the edge of the recess 112 formed on the transport surface 61M.

[0101] Embodiment 3 differs from Embodiment 1 in that the straightening section 103 does not have a swinging member 111. This configuration can be used when it is not possible for the leading portion SD of the cover tape TT of the carrier tape CT inserted from the carrier tape inlet 61A to bend upward, that is, when inserting the carrier tape CT from the carrier tape inlet 61A, the leading portion SD of the cover tape TT is bent downward in advance, that is, when inserting the carrier tape CT into the carrier tape inlet 61A with the leading portion SD bent downward. In Embodiment 3 as well, the straightening section 103 has a straightening edge, so the same effect as the tape feeder 16 in Embodiment 1 can be obtained.

[0102] (Embodiment 4) Figure 28 shows a part of the tape feeder in Embodiment 4. The tape feeder in Embodiment 4 is the same as the tape feeder 16 in Embodiment 1, except that it does not have the air ejection section 65 that appeared in Embodiment 1, and instead has a duct 130 that covers the cover tape discharge passage 102 and a suction section 131 that sucks in air 107 provided inside the duct 130. The guide section 140 of Embodiment 4 has a configuration that includes a first tape holder 71 and a suction section 131.

[0103] In Embodiment 4, the suction unit 131, located above the transport surface 61M, sucks in the air 107 inside the duct 130. This eliminates the need for the air ejection unit 65 in Embodiment 1, ensuring that the lead portion SD of the cover tape TT is reliably drawn into the cover tape retraction unit 101 by passing through the cover tape passage 75. In other words, in Embodiment 4, the suction unit 131, like the air ejection unit 65 described above, is an auxiliary unit that utilizes the flow of gas to assist in the movement of the lead portion SD toward the cover tape retraction unit 101. The suction unit 131, like the air ejection unit 65, also functions to guide the tip SS of the lead portion TT of the cover tape TT toward the cover tape retraction unit 101. Therefore, in Embodiment 4, the same effects as the tape feeder 16 in Embodiment 1 can be obtained.

[0104] (Embodiment 5) Figure 29 shows a part of the tape feeder in Embodiment 5. The tape feeder in Embodiment 5 is the same as the tape feeder 16 in Embodiment 1, except that it does not have the air ejection section 65 that appeared in Embodiment 1, and instead a guide member 132 is provided on the downstream side above the cover tape passage 75. In addition, the stopper 76 has been changed to a shape that makes it easier to direct the leading section SD of the cover tape TT upward from the cover tape passage 75, rather than blocking its progress. The guide section 140 in Embodiment 5 is configured to include a first tape retainer 71 and a guide member 132.

[0105] In Embodiment 5, the leading portion SD, which has come into contact with the stopper 76, changes its direction of movement upward and protrudes above the tape cover 70 through the cover tape passage 75. The leading portion SD of the cover tape TT, which has moved above the tape cover 70, is guided towards the cover tape retraction portion 101 by the guide member 132. As a result, the leading portion SD of the cover tape TT is reliably captured by the cover tape retraction portion 101, and the same effect as the tape feeder 16 in Embodiment 1 can be obtained.

[0106] (Embodiment 6) Figure 30 shows a part of the tape feeder in Embodiment 6. The tape feeder in Embodiment 6 does not have an air ejection section 65, and is the same as the tape feeder 16 in Embodiment 1, except that the shape of the stopper 76 of the tape cover 70 (especially its height from the transport surface 61M) and the size and arrangement of the drive roller 101a and driven roller 101b that constitute the cover tape pull-in section 101 differ from those in Embodiment 1. In addition, the stopper 76 has been modified to a shape that makes it easier to direct the lead section SD of the cover tape TT upward from the cover tape passage 75, rather than blocking its progress. The guide section 140 in Embodiment 6 consists only of the first tape retainer 71.

[0107] In Embodiment 6, the leading portion SD of the cover tape TT, which protrudes above the tape cover 70 through the cover tape passage 75, can be guided to the cover tape retraction portion 101 without requiring the aforementioned auxiliary parts (air ejection portion 65, suction portion 131, guide member 132, etc.). Therefore, in Embodiment 6, the same effects as the tape feeder 16 in Embodiment 1 can be obtained.

[0108] As described above, the component supply device (tape feeder 16) in embodiments 1 to 6 includes a guide section that guides the lead section SD toward the cover tape pull-in section 101, including a stopper 76 positioned on the transport surface 61M. The lead section SD of the cover tape TT is blocked by the stopper 76 and guided by the guide section. This ensures that the cover tape TT can be reliably separated from the carrier tape CT. After the lead section SD of the cover tape TT is captured by the cover tape pull-in section 101, the stopper 76 is lifted upward by the height change section 70T, so the carrier tape CT can proceed along the transport path 61 without being blocked by the stopper 76, and the transport of the carrier tape CT is not hindered.

[0109] 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, instead of the configuration in which the oscillating member 111 is in an oscillating restricted state and the oscillating member edge 111c is separated from the transport path 61 while waiting for the carrier tape CT to advance, the oscillating member edge 111c may be brought into contact with the transport surface 61M while waiting for the carrier tape CT to advance. In this case, the transport surface 61M may function as the oscillating restricted member in Embodiment 1. [Industrial applicability]

[0110] The present invention provides a parts supply device that can reliably peel the cover tape from the carrier tape. [Explanation of symbols]
