Description

The present disclosure relates to a tape cutting device that cuts a component supply tape used in a component supply device, and an adjustment method for adjusting the position of a cutting edge of a blade in the tape cutting device.

For example, Patent Document 1 discloses a component supply device that uses a component supply tape. The component supply tape is composed of a carrier tape having a plurality of recesses (component pockets) each containing a component, and a cover tape attached to the carrier tape so as to cover the plurality of recesses.

JP2020-9931A

By the way, in the case of the component supply device described in Patent Document 1, the component supply tape requires that the tip end portion of the cover tape in the longitudinal direction extend beyond the tip end in the longitudinal direction of the carrier tape. However, in component supply tapes supplied by suppliers, the leading edge of the carrier tape and the leading edge of the cover tape are aligned. Therefore, it is necessary to cut only the leading end portion of the carrier tape without cutting the cover tape.

However, the thickness of the carrier tape varies depending on the type.

Therefore, the present disclosure provides a component supply tape composed of a carrier tape and a cover tape attached to the carrier tape, in which the carrier tape can be applied without cutting the cover tape even if the carrier tapes have different thicknesses. The task is to cut only the tip side of the.

FIG. 1 is a perspective view of a tape cutting device according to an embodiment of the present disclosure. Moreover, FIG. 2 is a side view of the tape cutting device. Note that an XYZ orthogonal coordinate system is shown in the drawings to facilitate understanding of the present disclosure. The X-axis direction indicates the width direction (tape width direction) of the component supply tape, the Y-axis direction indicates the longitudinal direction (tape longitudinal direction), and the Z-axis direction indicates the thickness direction (tape thickness direction). This XYZ coordinate system does not limit the embodiments of the present disclosure.

As shown in FIGS. 1 and 2, tape cutting device 10 according to the present embodiment is configured to cut component supply tape 100. As shown in FIGS. Before explaining the structure of the tape cutting device 10, first, cutting of a component supply tape by the tape cutting device 10 will be explained with reference to FIGS. 3A to 3C.

FIG. 3A is a perspective view of an example component supply tape cut by a tape cutting device according to an embodiment of the present disclosure. Moreover, FIG. 3B is a perspective view of an example of the component supply tape in a state where both the carrier tape and the cover tape have been cut by the tape cutting device. FIG. 3C is a perspective view of an example of the component supply tape in which only the carrier tape has been cut by the tape cutting device.

As shown in FIG. 3A, the component supply tape 100 includes a carrier tape 102 and a cover tape 104 attached to the carrier tape 102.

Specifically, the carrier tape 102 is made of, for example, a resin material or a paper material, and includes a first surface 102a and a second surface 102b opposite thereto. A plurality of concave component pockets 102c for accommodating components (not shown) are formed on the first surface 102a. The plurality of component pockets 102c are lined up in the tape longitudinal direction (Y-axis direction) of the carrier tape 102. Further, the carrier tape 102 includes a plurality of feed holes 102d arranged in the tape longitudinal direction and engaged with sprockets of the component supply device.

The cover tape 104 is made of, for example, a resin material, and is attached to the first surface 102a of the carrier tape 102 so as to cover the plurality of component pockets 102c.

In the case of this embodiment, as shown in FIG. 3B, the tape cutting device 10 cuts the tip end portion of the component supply tape 100, that is, the tip end portion 102e of the carrier tape 102 and the cover tape 104 attached to that portion. It is configured to cut the tip side portion 104a. This is to create a new tip 100a on the component supply tape 100.

In addition, in the case of this embodiment, as shown in FIG. 3C, in the component supply tape 100 in which a new tip 100a has been produced, the tape cutting device 10 cuts a new part of the carrier tape 102 without cutting the cover tape 104. It is configured to cut the distal end portion 102f. As a result, the new leading end portion 104b of the cover tape 104 is placed in a state where it extends beyond the new leading end 102g of the carrier tape 102 in the tape longitudinal direction (Y-axis direction).

Note that in the component supply tape 100 shown in FIGS. 3A to 3C, the second surface 102b of the carrier tape 102 is configured as a flat surface. However, as shown in FIG. 2, the tape cutting device 10 according to the present embodiment has a plurality of embossed portions 102h lined up in the tape longitudinal direction (Y-axis direction) on the second surface 102b' of the carrier tape 102'. The component supply tape 100' provided with ' is also configured to be cuttable.

As shown in FIGS. 1 and 2, tape cutting device 10 according to the present embodiment includes a cutting unit 20 for cutting component supply tape 100. As shown in FIGS.

FIG. 4 is a perspective view of the cutting unit. Moreover, FIG. 5 is a front exploded perspective view of the cutting unit. FIG. 6 is a rear exploded perspective view of the cutting unit.

As shown in FIGS. 4 to 6, in this embodiment, the cutting unit 20 is roughly composed of three parts. Specifically, the cutting unit 20 includes a blade support block (blade support member) 22, a tape pressing head (tape pressing member) 24, and a tape holder (tape holding member) 26.

The blade support block 22 and the tape pressing head 24 are arranged to face each other in the tape thickness direction (Z-axis direction), and move closer to or apart from each other in the tape thickness direction, as will be described in detail later. The tape holder 26 is provided so as to be movable in the tape thickness direction with respect to the blade support block 22, although the details will be described later. First, the details of these three components will be explained.

FIG. 7 is an exploded perspective view of the blade support block 22.

In the case of this embodiment, the blade support block 22 in the cutting unit 20 is a generally rectangular parallelepiped-shaped block that supports the first blade 30 and the second blade 32. One first blade 30 is a blade for cutting both the carrier tape 102 and the cover tape 104, as shown in FIG. 3B. The other second blade 32 is a blade for cutting only the carrier tape 102, as shown in FIG. 3C.

In the case of this embodiment, the first and second blades 30 and 32 are common square blades, and have straight cutting edges 30a and 32a. Further, the first and second blades 30 and 32 are supported by the blade support block 22 in a parallel state when viewed in the tape thickness direction (Z-axis direction). However, the first and second blades 30 and 32 are provided on the blade support block 22 in different postures and at different positions in the tape longitudinal direction (as viewed in the Y-axis direction). The reason for this will be explained later.

Further, the first blade 30 is immovably supported (fixed) on the blade support block 22. Specifically, in the case of this embodiment, the first blade 30 includes a through hole 30b. The first blade 30 is fixed to the blade support block 22 by a fixing screw 36 passing through the through hole 30b and the plate washer 34 engaging with a screw hole formed in the blade support block 22.

Unlike the first blade 30, in this embodiment, the second blade 32 is supported by the blade support block 22 so as to be movable, particularly in the tape thickness direction (Z-axis direction). This is because the second blade 32 only cuts the carrier tape 102, unlike the first blade 30 which cuts both the carrier tape 102 and the cover tape 104. That is, it is necessary to adjust the position of the second blade 32 in the tape thickness direction with respect to the blade support block 22 so as to cut only the carrier tape 102 without cutting the cover tape 104.

Specifically, as a component for adjusting the position of the second blade 32, the blade support block 22 is provided with a biasing member 38 that biases the second blade 32 toward the tape pressing head 24. It is being In addition, in the case of this embodiment, the biasing member 38 is a compression spring.

Further, in the case of this embodiment, the biasing member 38 biases the second blade 32 via the blade receiving member 40. The blade receiving member 40 is a member that receives the end 32b of the second blade 32 opposite to the cutting edge 32a, and is provided on the blade support block 22 so as to be movable in the tape thickness direction (Z-axis direction). . Specifically, the blade receiving member 40 has a long hole 40a that is long in the tape thickness direction, and is supported movably in the tape thickness direction by a guide screw 42 that passes through the long hole 40a. Note that the guide screw 42 is a screw that includes a head, a guide pin portion extending from the head, and a male thread portion provided at the tip of the guide pin portion. By using such a blade receiving member 40, the biasing member 38 can bias the thin second blade 32.

Further, in the case of the present embodiment, after the position adjustment with respect to the blade support block 22 is completed, the second blade 32 is fixed to the blade support block 22 by the blade fixing member 44 in order to maintain the adjusted position. be done. In this embodiment, the blade fixing member 44 is a fixing screw. The fixing screw 44 passes through the through hole 32c of the second blade 32 and the plate washer 46, and engages with a screw hole formed in the blade support block 22. Furthermore, the through hole 32c of the second blade 32 has a diameter that is sufficiently larger than the diameter of the threaded portion of the fixing screw 44.

Therefore, by tightening the fixing screw 44, the second blade 32 is fixed to the blade support block 22. On the other hand, by loosening it, the second blade 32 becomes movable in the tape thickness direction (Z-axis direction). That is, the second blade 32 is supported by the blade support block 22 so as to be movable in the tape thickness direction.

A method for adjusting the position of the second blade 32 with respect to the blade support block 22 using the biasing member 38, blade receiving member 40, and fixing screw 44 will be described later.

As shown in FIGS. 4 to 6, the tape holding head 24 presses the tape against the blade support block 22, that is, the cutting edges 30a and 32a of the first and second blades 30 and 32 provided on the blade support block 22. They face each other in the thickness direction (Z-axis direction). The component supply tape 100 is placed between the tape pressing head 24 and the cutting edges 30a and 32a of the first and second blades 30 and 32, with the cover tape 104 facing the tape pressing head 24. In this state, the blade support block 22 and the tape pressing head 24 approach each other, so that the component supply tape 100 is cut by the first and second blades 30 and 32.

In the case of this embodiment, the blade support block 22 and the tape pressing head 24 are brought close to each other manually by the operator.

To this end, as shown in FIGS. 1 and 2, the tape cutting device 10 includes a first arm 12A rotatably connected to a blade support block 22, and a first arm 12A rotatably connected to a tape pressing head 24. A second arm 12B, first and second operating levers 14A, 14B that are grasped and operated by an operator, and a first link 16A that connects the first arm 12A and second operating lever 14B; It has a second link 16B that connects the second arm 12B and the first operating lever 14A. The first link 16A and the second link 16B are rotatably connected to each other around a rotation center line extending in the longitudinal direction of the tape (Y-axis direction), and constitute an X-link mechanism. are doing.

A blade support block 22 is connected to the tip of the first arm 12A so as to be rotatable about a rotation center line extending in the tape longitudinal direction (Y-axis direction). The first arm 12A is attached to one end of the first link 16A of the X-link mechanism, and is rotatable about a rotation center line extending in the longitudinal direction of the tape and movable in the tape width direction (X-axis direction). is connected to.

A tape pressing head 24 is connected to the tip of the second arm 12B so as to be rotatable about a rotation center line extending in the tape longitudinal direction (Y-axis direction). The second arm 12B is attached to one end of the second link 16B of the X-link mechanism, and is rotatable about a rotation center line extending in the longitudinal direction of the tape and movable in the tape width direction (X-axis direction). is connected to.

The first operating lever 14A is rotatably connected to the other end of the second link 16B about a rotation center line extending in the tape longitudinal direction (Y-axis direction).

The second operating lever 14B is rotatably connected to the other end of the first link 16A about a rotation center line extending in the tape longitudinal direction (Y-axis direction).

According to such a connection between the first and second arms 12A, 12B and the first and second operating levers 14A, 14B, the first and second operating levers 14A, 14B can be moved closer to each other by the operator's operation. Then, the first and second arms 12A, 12B also approach. As a result, the blade support block 22 and tape pressing head 24 approach each other.

As shown in FIGS. 4 to 6, in order to position the blade support block 22 and tape pressing head 24 relative to each other in the tape width direction (X-axis direction) and tape longitudinal direction (Y-axis direction), the tape pressing head 24 is , a guide rod 48. The guide rod 48 extends toward the blade support block 22 in the tape thickness direction (Z-axis direction) and engages with a guide hole 22a provided in the blade support block 22. When the guide rod 48 and the guide hole 22a engage with each other, the blade support block 22 and the tape pressing head 24 move in parallel and approach each other.

Further, as a positioning component, the blade support block 22 includes a plurality of positioning pins 50 . The plurality of positioning pins 50 extend toward the tape pressing head 24 in the tape thickness direction (Z-axis direction).

FIG. 8 is a perspective view showing the tape pressing surface of the tape pressing head in the cutting unit.

As shown in FIG. 8, the tape pressing head 24 includes a plurality of positioning holes 24a on a surface facing the blade support block 22, which engage with a plurality of positioning pins 50 provided on the blade support block 22. These positioning pins 50 and positioning holes 24a are arranged so that when the blade support block 22 and tape pressing head 24 approach each other to a certain extent, for example, just before the first blade 30 of the blade support block 22 starts cutting the component supply tape 100. Then, engage.

As shown in FIG. 8, the tape pressing head 24 includes a tape pressing surface 24b facing the cutting edges 30a, 32a of the first and second blades 30, 32 supported by the blade support block 22. The tape pressing surface 24b contacts the cover tape 104 of the component supply tape 100. As a result, when the first and second blades 30 and 32 of the blade support block 22 cut the component supply tape 100 from the second surface 102b of the carrier tape 102, the tape pressing surface 24b holds the component supply tape 100. To support.

The tape pressing head 24 contacts the cover tape 104 with its tape pressing surface 24b, but does not contact the first surface 102a of the carrier tape 102 due to the thickness of the cover tape 104. Therefore, when the tape pressing head 24 is in contact with the cover tape 104, a gap is created between the tape pressing head 24 and a portion of the first surface 102a of the carrier tape 102 to which the cover tape 104 is not attached. The tape pressing head 24 includes a gap filling part that fills this gap.

In the case of this embodiment, a resin plate 52 is provided on the tape pressing head 24 as a gap filling portion of the tape pressing head 24. The resin plate 52 includes a contact surface 52a that contacts the carrier tape 102 when the tape pressing surface 24b of the tape pressing head 24 is in contact with the cover tape 104. Note that the role of this resin plate 52 will be described later.

Further, the tape holding head 24 includes a recess, for example, a groove 24c, which accommodates the cutting edge 30a of the first blade 30 after cutting the component supply tape 100, although the details will be described later.

As shown in FIGS. 4 to 6, the tape holder 26 is a member for holding the component supply tape 100 and thereby maintaining the component supply tape 100 between the blade support block 22 and the tape pressing head 24. .

FIG. 9 is a top view of the tape holder holding the component supply tape.

As shown in FIG. 9, the tape holder 26 includes first and second tape holding surfaces 26a and 26b on which the component supply tape 100 is held, that is, placed, at the end on the tape pressing head 24 side. The first and second tape holding surfaces 26a and 26b are arranged at intervals in the tape longitudinal direction (Y-axis direction). The cutting edges 30a, 32a of the first and second blades 30, 32 of the blade support block 22 pass between the first and second tape holding surfaces 26a, 26b.

In the case of this embodiment, as shown in FIGS. 5 and 6, the first tape holding surface 26a is divided into two in the tape width direction (X-axis direction). Similarly, the second tape holding surface 26b is also divided into two parts. This is because the tape cutting device 10 according to the present embodiment has a plurality of embossed portions lined up in the tape longitudinal direction (Y-axis direction) on the second surface 102b' of the carrier tape 102', as shown in FIG. This is because it also corresponds to the component supply tape 100' provided with 102h'. That is, a concave relief portion 26c for avoiding contact with the embossed portion 102h' is formed by dividing each of the first and second tape holding surfaces 26a and 26b into two in the tape width direction. . When the tape cutting device 10 does not support a component supply tape having an embossed portion, each of the first and second tape holding surfaces 26a and 26b may be a continuous surface without being divided into two.

Further, as shown in FIGS. 4 to 6, one of the two-divided first tape holding surface 26a has a feed hole 102d of the carrier tape 102 extending in the tape thickness direction (Z-axis direction). A plurality of engaging positioning pins 54 are provided. By engaging this positioning pin 54 with the feed hole 102d, the component supply tape 100 is positioned with respect to the tape holder 26 in the tape width direction (X-axis direction) and tape longitudinal direction (Y-axis direction).

As shown in FIGS. 4 to 6, in the case of the present embodiment, the tape holder 26 has a square bracket shape when viewed in the tape thickness direction (Z-axis direction), and the blade support block 22 when viewed in the tape thickness direction. is provided on the blade support block 22 so as to at least partially cover the blade support block 22 . That is, the tape holder 26 is provided on the blade support block 22 so as to at least partially surround the first and second blades 30 and 32 supported by the blade support block 22 when viewed in the tape thickness direction.

Further, the tape holder 26 is provided on the blade support block 22 so as to be movable in the tape thickness direction (Z-axis direction). Specifically, a guide hole 26d that is long in the tape thickness direction (Z-axis direction) is formed in the tape holder 26. The blade support block 22 is provided with a guide screw 56 that passes through the guide hole 26d and engages with a female threaded hole of the blade support block 22. Thereby, the tape holder 26 is held by the blade support block 22 so as to be movable in the tape thickness direction (Z-axis direction).

Furthermore, in the case of this embodiment, the tape holder 26 is suspended from the blade support block 22 via a tension spring 58. A hanging pin 60 on which one end of the tension spring 58 is hooked is provided in a portion of the blade support block 22 on the tape pressing head 24 side. On the other hand, a hook portion 26e on which the other end of the tension spring 58 is hooked is provided at the end of the tape holder 26 that is far from the tape pressing head 24.

This tension spring 58 allows the tape holder 26 to overlap the cutting edges 30a and 32a of the first and second blades 30 and 32 when viewed in the tape width direction (X-axis direction) and the tape longitudinal direction (Y-axis direction). maintained. As a result, the tape holder 26 functions as a cover member that protects the cutting edges 30a, 32a of the first and second blades 30, 32 and suppresses contact between the cutting edges 30a, 32a and the operator. Further, although the details will be described later, when the tape holder 26 comes into contact with the tape pressing head 24 while the blade supporting block 22 is moving toward the tape pressing head 24, the tape holder 26 moves relative to the blade supporting block 22, and the tape The cutting edges 30a, 32a of the first and second blades 30, 32 protrude from the tape holder 26 when viewed in the width direction and tape longitudinal direction.

Up to this point, the structure of the cutting unit in the tape cutting device 10 has been described. The operation of the cutting unit will now be described, as well as further features of the components of the cutting unit.

10A and 10B are a side view and a cross-sectional view of the cutting unit with the component supply tape set therein.

As shown in FIGS. 10A and 10B, the component supply tape 100 is set on the first and second tape holding surfaces 26a and 26b of the tape holder 26 with the blade support block 22 and tape pressing head 24 separated. (placed). Further, the component supply tape 100 is set so that the cover tape 104 faces the tape pressing surface 24b of the tape pressing head 24. Note that FIGS. 10A and 10B show a state in which the blade support block 22 and the tape pressing head 24 are farthest apart.

As shown in FIG. 10A, in this embodiment, the cutting edge 30a of the first blade 30 is located closer to the tape pressing surface 24b of the tape pressing head 24 than the cutting edge 32a of the second blade 32. Thereby, after the cutting edge 30a of the first blade 30 cuts both the carrier tape 102 and the cover tape 104, the cutting edge 32a of the second blade 32 can start cutting the carrier tape 102. As a result, cutting resistance can be reduced compared to the case where the cutting edges 30a and 32a of the first and second blades 30 and 32 simultaneously cut the carrier tape 102. In the case of this embodiment, an operator can cut component supply tape 100 with small force.

Further, the cutting edge 30a of the first blade 30 is non-parallel to the tape pressing surface 24b of the tape pressing head 24. In the case of this embodiment, the cutting edge 30a is a straight line inclined with respect to the tape pressing surface 24b when viewed in the tape longitudinal direction (Y-axis direction). Thereby, cutting resistance can be reduced compared to the case where the cutting edge 30a is parallel to the tape pressing surface 24b of the tape pressing head 24. The reason for this is that when the cutting edges 30a are parallel, cutting resistance is large because the carrier tape 102 is cut across its entire width (X-axis direction) at the same time. Note that the cutting edge 30a of the first blade 30 is not limited to a linear shape, but may be, for example, an arc shape.

On the other hand, unlike the cutting edge 30a of the first blade 30, the cutting edge 32a of the second blade 32 is parallel to the tape pressing surface 24b of the tape pressing head 24, that is, it is in contact with the tape pressing surface 24b. The cover tape 104 is parallel to the cover tape 104 . This is to ensure that the carrier tape 102 is cut without cutting the cover tape 104.

Furthermore, as shown in FIGS. 10A and 10B, the cutting edges 30a and 32a of the first and second blades 30 and 32 are tape-like when viewed in the tape width direction (X-axis direction) and the tape longitudinal direction (Y-axis direction). It overlaps the holder 26. That is, the cutting edges 30a and 32a of the first and second blades 30 and 32 are located on the opposite side of the tape holding head 24 with respect to the tape holding surfaces 26a and 26b of the tape holder 26. As a result, when setting the component supply tape 100 on the first and second tape holding surfaces 26a and 26b of the tape holder 26, the operator's fingers are prevented from coming into contact with the cutting edges 30a and 32a.

Note that, as shown in FIGS. 10A and 10B, when the blade support block 22 and tape pressing head 24 are farthest apart, the tape holder 26 overlaps the cutting edges 30a and 32a of the first and second blades 30 and 32. In order to maintain the condition, a hook 62 is provided on the tape pressing head 24. The hook 62 hooks onto the tape holder 26 and restricts the tape holder 26 from moving away from the tape pressing head 24. Thereby, the tape holder 26 does not move and the cutting edges 30a, 32a of the first and second blades 30, 32 do not protrude from the tape holder 26, and the contact between the operator's fingers and the cutting edges 30a, 32a is prevented. suppressed.

As shown in FIGS. 10A and 10B, after the component supply tape 100 is set in the cutting unit 20, the blade support block 22 and tape pressing head 24 approach each other. In the case of the present embodiment, the blade support block 22 and the tape pressing head 24 approach each other by the operator's operation of moving the first and second operating levers 14A, 14 closer to each other.

11A and 11B are side and cross-sectional views of the cutting unit with the component supply tape clamped.

When the blade support block 22 and the tape press head 24 approach each other, the tape holder 26 provided on the blade support block 22 comes into contact with the tape press head 24, as shown in FIGS. 11A and 11B. In the case of this embodiment, the tape holder 26 contacts the tape pressing head 24 via the component supply tape 100 that it holds. Thereby, the component supply tape 100 is clamped (held) by the tape pressing head 24 and the tape holder 26.

As shown in FIG. 11A, when the component supply tape 100 is in a clamped state, the tape pressing surface 24b of the tape pressing head 24 is in contact with the cover tape 104. Further, the resin plate 52 is in contact with the portion of the carrier tape 102 to which the cover tape 104 is not attached. The component supply tape 100 is clamped by the resin plate 52 in such a manner that the entire component supply tape 100 cannot be displaced toward the tape pressing head 24 side. The effect of this resin plate 52 will be specifically explained.

FIG. 12A shows the carrier tape cut by the second blade in the presence of resin plate 52. Moreover, FIG. 12B shows the carrier tape cut by the second blade in the case where the resin plate 52 is not present.

As mentioned above, the second blade 32 cuts only the carrier tape 102. At that time, if the resin plate 52 is not present, there is a possibility that the carrier tape 102 will be left uncut.

Specifically, the portion of the carrier tape 102 to which the cover tape 104 is attached is in contact with the tape pressing surface 24b of the tape pressing head 24 via the cover tape 104. Therefore, even if that portion is pushed by the second blade 32, it cannot escape to the tape pressing surface 24b side. Therefore, the portion of the carrier tape 102 to which the cover tape 104 is attached is cut by the cutting edge 32a of the second blade 32.

On the other hand, as shown in FIG. 12B, a space S is formed between the portion of the carrier tape 102 to which the cover tape 104 is not attached and the tape pressing head 24. Therefore, that portion can be pushed by the second blade 32 and escape toward the tape pressing surface 24b. As a result, there is a possibility that uncut portions of the carrier tape 102 to which the cover tape 104 is not attached may be left uncut.

To deal with this, as shown in FIG. 12A, a resin plate 52 is provided to fill the gap between the portion of the carrier tape 102 to which the cover tape 104 is not attached and the tape pressing head 24. Due to this resin plate 52, the portion of the carrier tape 102 to which the cover tape 104 is not attached cannot escape to the tape pressing head 24 side even if pushed by the second blade 32. As a result, the portion of the carrier tape 102 to which the cover tape 104 is not attached is cut by the cutting edge 32a of the second blade 32.

Further, as shown in FIG. 10A, the distance D from the tape pressing surface 24b of the tape pressing head 24 to the contact surface 52a of the resin plate 52 that contacts the carrier tape 102 is equal to or greater than the thickness of the cover tape 104. preferable. For example, when the thickness of the cover tape 104 is 50 μm, the distance D is 100 μm. When the thickness of the resin plate 52 is greater than the thickness of the cover tape 104, at least one of the resin plate 52 and the carrier tape 102 is deformed. This further reduces the possibility of uncut portions of the carrier tape 102 to which the cover tape 104 is not attached.

Furthermore, as shown in FIG. 9, the contact surface 52a of the resin plate 52 preferably extends beyond the end of the carrier tape 102 in the tape width direction (X-axis direction). Thereby, the portion of the carrier tape 102 to which the cover tape 104 is not attached is more reliably suppressed from being pushed by the second blade 32 and escaping. As a result, the possibility of uncut portions of the carrier tape 102 to which the cover tape 104 is not attached is further reduced.

Note that the gap-filling member that fills the gap between the portion of the carrier tape 102 to which the cover tape 104 is not attached and the tape pressing head 24 may be a resin plate as long as it does not damage the cutting edge 32a of the second blade 32. Not limited to. Further, the gap filling member may be provided as a part of the tape pressing head 24 (as a gap filling portion) instead of being a separate component of the tape pressing head 24.

As shown in FIGS. 11A and 11B, after the tape holder 26 contacts the tape holding head 24 via the component supply tape 100, the blade support block 22 moves relative to the tape holder 26, thereby causing the tape toward the pressing head 24. As a result, the cutting edge 30a of the first blade 30 supported by the blade support block 22 starts cutting the component supply tape 100.

13A and 13B are side and cross-sectional views of the cutting unit with the first blade beginning to cut the component supply tape.

As shown in FIGS. 13A and 13B, the cutting edge 30a of the first blade 30 begins to cut the component supply tape 100 that is clamped by the tape pressing head 24 and the tape holder 26. At this time, the cutting edge 30a of the first blade 30 starts cutting the component supply tape 100 (both the carrier tape 102 and the cover tape 104) from one end in the tape width direction (X-axis direction). Note that the blade edge 30a that has cut and passed through the component supply tape 100 is accommodated in the groove 24c of the tape pressing head 24. On the other hand, the cutting edge 32a of the second blade 32 has not reached the carrier tape 102 and has not started cutting.

As the blade support block 22 approaches the tape pressing head 24 further, the cutting edge 30a of the first blade 30 further cuts the component supply tape 100 (both the carrier tape 102 and the cover tape 104).

14A and 14B are a side view and a cross-sectional view of the cutting unit while the first blade 30 is cutting the component supply tape 100.

14A and 14B show a state in which the cutting edge 30a of the first blade 30 has cut more than half of the component supply tape 100. On the other hand, the cutting edge 32a of the second blade 32 has not reached the carrier tape 102 and has not started cutting.

When the blade support block 22 approaches the tape pressing head 24 further, the cutting edge 30a of the first blade 30 completely cuts the component supply tape 100 (both the carrier tape 102 and the cover tape 104). As a result, a new tip 100a is created on the component supply tape 100, as shown in FIG. 3B. Then, the cutting edge 32a of the second blade 32 starts cutting the carrier tape 102.

15A and 15B are a side view and a cross-sectional view of the cutting unit in a state where the second blade has completed cutting the carrier tape.

As shown in FIGS. 15A and 15B, the cutting edge 32a of the second blade 32 completes cutting of the carrier tape 102 at the timing when the blade support block 22 and tape pressing head 24 come closest to each other. That is, when the blade support block 22 and the tape pressing head 24 are in the closest position, the cutting edge 32a of the second blade 32 touches the tape pressing surface 24b of the tape pressing head 24 with a distance approximately equal to the thickness of the cover tape 104. to face. The substantially equal distance means that the distance between the cutting edge 32a of the second blade 32 and the tape pressing surface 24b is t×0.9 or more and t or less, where t is the thickness of the cover tape 104. do.

In this way, when the blade support block 22 and the tape pressing head 24 are in the closest position, the blade edge 32a is arranged to face the tape pressing surface 24b of the tape pressing head 24 with a distance approximately equal to the thickness of the cover tape 104. , the position of the cutting edge of the second blade 32 with respect to the blade support block 22 is adjusted. The position adjustment method will be explained.

16A to 16C are diagrams for explaining the process of adjusting the cutting edge position of the second blade.

As shown in FIG. 16A, when adjusting the position of the cutting edge of the second blade 32, the tape holder 26 is removed from the blade support block 22. Further, a metal shim plate SP having the same thickness t as the cover tape 104 of the component supply tape 100 is prepared, and is provided between the tape pressing surface 24b of the tape pressing head 24 and the cutting edge 32a of the second blade 32. Placed.

First, the fixing screw 44 is loosened in order to allow the second blade 32 to move relative to the blade support block 22. As a result, the second blade 32 is urged toward the tape pressing head 24 via the blade receiving member 40 by the urging member 38 .

Next, as shown in FIG. 16B, the blade support block 22 and tape pressing head 24 are brought into the closest position. As a result, the cutting edge 32a of the second blade 32 comes into contact with the shim plate SP. Due to the contact, the second blade 32 moves in a direction away from the tape pressing head 24 against the biasing force of the biasing member 38.

Then, the fixing screw 44 is tightened with the cutting edge 32a of the second blade 32 in contact with the shim plate SP. As a result, as shown in FIG. 16C, when the blade support block 22 and tape pressing head 24 are in the closest position, the distance between the cutting edge 32a of the second blade 32 and the tape pressing surface 24b becomes smaller than that of the cover tape 104. The second blade 32 is fixed to the blade support block 22 so as to substantially match the thickness t. The distance is preferably equal to the thickness t of the cover tape 104, but may be greater than or equal to t×0.9 and less than or equal to t.

By adjusting the position of the second blade 32 with respect to the blade support block 22 in this way, the cutting edge 32a of the second blade 32 can cut only the carrier tape 102 without cutting the cover tape 104, as shown in FIG. 15B. can do.

According to this embodiment as described above, in a component supply tape composed of a carrier tape and a cover tape attached to the carrier tape, even if the carrier tapes have different thicknesses, the cover tape can be cut. It is possible to cut only the tip side portion of the carrier tape without cutting. That is, since it is possible to adjust the distance between the tape pressing surface that contacts the cover tape and the cutting edge of the second blade, only the tip side portion of the carrier tape can be cut without cutting the cover tape. be able to.
