Description

[Technical Field]

[0001] The present invention relates to a carrier tape cutting device that cuts a base tape, which is made by adhering a cover tape to a base tape that houses components, while leaving the cover tape. [Background technology]

[0002] Conventionally, as a component supply means in a component mounting device that mounts components on a circuit board, a tape feeder is known that supplies components using a carrier tape that is made up of a base tape that stores components and a cover tape attached thereto. There are various types of tape feeders, and among them, there is one that requires the carrier tape to be processed so that the tip of the cover tape is longer than the tip of the base tape when loaded (for example, Patent Document 1 below).

[0003] In order to make the tip of the cover tape of the carrier tape longer than the tip of the base tape, it is necessary to cut and remove a part of the base tape from the tip of the carrier tape. The carrier tape cutting device shown in Patent Document 2 is a tool for performing such processing, and is configured so that when two levers (a first operating lever and a second operating lever) connected by a link are moved toward each other, the cutter and tape pressing member move toward each other while maintaining their parallel positions, and the tape pressing member presses the carrier tape against the cutter to cut the base tape. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-125625 [Patent Document 2] Patent Publication No. 2021-122568 Summary of the Invention [Problem to be solved by the invention]

[0005] The carrier tape cutting device shown in Patent Document 2 has the drawback of being large in size and inconvenient to carry. One possible solution to this problem is to provide a cutter on one of two handle sections whose base ends are pivotally connected to each other and can be opened and closed, and to provide a pressing member on the other of the two handles, and to operate the two handle sections in the closing direction to pinch the carrier tape, thereby adopting a small and simple configuration in which the pressing member presses the carrier tape against the cutter.

[0006] However, in this configuration, the pressing member moves in an arcuate orbit centered on the pivot axis and contacts the carrier tape, so the carrier tape is not cut with uniform force across the width, and there is a risk that part of the base tape may not be completely cut, resulting in inconsistent cutting.

[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a carrier tape cutting device that is small in size and has a simple configuration, yet is capable of cutting a base tape stably. [Means for solving the problem]

[0008] The carrier tape cutting device of the present invention is a carrier tape cutting device that cuts a base tape, which is made of a cover tape affixed to a base tape that stores components, while leaving the cover tape behind, and comprises: a main body portion consisting of a first handle portion and a second handle portion whose base ends are pivotally connected to each other and can be opened and closed about a pivot axis; a tape holding portion attached to the first handle portion and holding the carrier tape; a cutter attached to the first handle portion and having a blade positioned opposite the base tape when the carrier tape is held by the tape holding portion; a pressing member attached to the second handle portion and contacting the carrier tape held by the tape holding portion to press the base tape against the cutter when the first handle portion and the second handle portion are operated in a closing direction; and a regulating means that regulates the pressing member from pressing the carrier tape against the cutter when the base tape pressed against the cutter by the pressing member is cut by the cutter, and the pressing member is attached to the second handle portion in a state where it can swing freely about an oscillation axis extending approximately parallel to the pivot axis. [Effects of the Invention]

[0009] According to the present invention, the base tape can be cut stably despite its small size and simple configuration. [Brief explanation of the drawings]

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 and 2 show a carrier tape cutting device 1 in one embodiment of the present invention. Before describing the configuration of the carrier tape cutting device 1, first, a carrier tape CT to be cut by the carrier tape cutting device 1 will be described.

[0012] As shown in Figure 3, the carrier tape CT is composed of a base tape BT and a cover tape TT. The base tape BT has a number of pockets PK for storing components lined up in a row along the longitudinal direction of the base tape BT (i.e., the carrier tape CT), and a number of sprocket holes KH are lined up in a row parallel to the row of pockets PK. Each pocket PK stores one component BH, and the cover tape TT is attached to the top surface of the base tape BT in a position that does not block the sprocket holes KH.

[0013] 3, the cover tape TT extends along the row of pockets PK on the base tape BT (i.e., along the longitudinal direction of the carrier tape CT) and is attached to the base tape BT in a position that covers the pockets PK without covering the sprocket holes KH. In other words, the cover tape TT is attached only to a partial area in the width direction of the carrier tape CT (the area that covers the pockets PK).

[0014] Next, we will explain the carrier tape cutting device 1. As shown in Figures 1 and 2, the main body 10 of the carrier tape cutting device 1 is equipped with a first handle portion 11 and a second handle portion 12. The first handle portion 11 and the second handle portion 12 are pivotally connected at one end in the longitudinal direction by a pivot shaft 13. Therefore, the first handle portion 11 and the second handle portion 12 can be opened and closed by rotating them around a pivot axis 13J, which is the central axis of the pivot shaft 13.

[0015] 1 and 2, the first handle portion 11 and the second handle portion 12 each have a pair of flanges FG extending from both widthwise ends, each having a groove-like cross section. When the first handle portion 11 and the second handle portion 12 are operated in the closing direction (directions in which they approach each other) (FIGS. 4(a) and (b)), the pair of flanges FG of the second handle portion 12 are positioned outside the pair of flanges FG of the first handle portion 11. One of the flanges FG of the first handle portion 11 has a notch portion 11K formed in a shape in which the upper edge side is cut out (FIGS. 1 and 4(a)).

[0016] 1 and 2, first handle portion 11 is provided with holder base 14, tape holder 15, cutter presser member 16, and cutter 17. Holder base 14 is made of a block-shaped member, and part of its upper surface (the surface facing second handle portion 12) forms flat contact surface 14M. Two guide protrusions 14P are provided on holder base 14 at locations different from contact surface 14M, and extend upward.

[0017] The tape holding portion 15 is made of a rectangular plate-shaped member. Two holding pins 15P protruding upward are provided on the upper surface of the tape holding portion 15, side by side in the width direction of the first handle portion 11. The distance between the two holding pins 15P matches the distance between two sprocket holes KH lined up on the carrier tape CT. The "distance between two sprocket holes KH" referred to here does not have to be the distance between two sprocket holes KH lined up next to each other, but may be the distance between two sprocket holes KH lined up every several holes.

[0018] 1 and 2, tape holding portion 15 is provided with elongated hole 15H extending in the width direction of first handle portion 11 and elongated guide groove 15M extending in the same direction. Fixing bolt 15N is threaded into the upper surface of holding portion base 14. Fixing bolt 15N passes through elongated hole 15H from above. The two aforementioned guide protrusions 14P provided on holding portion base 14 fit into guide groove 15M from below.

[0019] The tape holding portion 15 can be moved in the width direction of the first handle portion 11 by sliding the guide groove 15M relative to the two guide protrusions 14P, and the tape holding portion 15 can be fixed to the holding portion base 14 by screwing the fixing bolt 15N into the holding portion base 14. When changing the position of the tape holding portion 15 relative to the holding portion base 14 (the position of the first handle portion 11 in the width direction), the fixing bolt 15N is first loosened, the tape holding portion 15 is moved, and then the fixing bolt 15N is screwed in again.

[0020] In this manner, in this embodiment, the positions of the plurality of holding pins 15P provided in the tape holding portion 15 relative to the first handle portion 11 can be adjusted.

[0021] 1 and 2, two cutter holder members 16 are provided side by side along the longitudinal direction of the first handle portion 11 on the side surface of the holder base 14 (the side surface on which the notch 11K is provided). Each cutter holder member 16 is made of a screw member, as shown in FIG. 5 (FIG. 5 is a cross-sectional view taken along arrows V1-V1 in FIG. 1), and a male screw portion 16S is threaded into a female screw portion 14S formed on the side surface of the holder base 14. Each of these two cutter holder members 16 can be twisted (tightened or loosened) by inserting a tool (e.g., a screwdriver) into an insertion hole 11S (see also FIGS. 2 and 4(b)) formed in the flange FG of the first handle portion 11.

[0022] Cutter 17 is, for example, a commercially available replacement blade for a cutter. As shown in Figures 1, 2, 5, and 6, cutter 17 has blade 17H ​​facing upward (toward second handle portion 12) and is attached to the side of holder base 14 in an orientation extending in the longitudinal direction of first handle portion 11.

[0023] The cutter 17 is attached to the holder base 14 by fastening the two cutter holder members 16 to the side surfaces of the holder base 14 and sandwiching the cutter 17 between the side surfaces of the holder base 14 and flange portions 16C (FIG. 5) formed on the heads of the cutter holder members 16. At this time, the cutter 17 is positioned in the height direction by the edge of the ridge side (the side opposite the blade 17H, the lower side in FIG. 5) abutting against the upper edge of the neck portion 16N provided on each of the two cutter holder members 16, as shown in FIG. 5. The "neck portion 16N" refers to the cylindrical portion formed at the base of the male thread portion 16S of the cutter holder member 16, as shown in FIG. 5.

[0024] 1 and 2, a swing shaft 18 is attached to the second handle portion 12. The swing shaft 18 is supported at both ends by a pair of flanges FG of the second handle portion 12, and extends in the width direction of the second handle portion 12. Therefore, a swing axis 18J, which is the central axis of the swing shaft 18, is parallel to a pivot axis 13J, which is the central axis of the pivot shaft 13.

[0025] 1 and 2, a pressing member 19 is attached to the second handle portion 12. The pressing member 19 has a shape that extends along the longitudinal direction of the second handle portion 12, and its middle portion is supported by a swing shaft 18. That is, in this embodiment, the pressing member 19 is attached to the second handle portion 12 in a state in which it can swing freely around a swing axis 18J that extends substantially parallel to the pivot axis 13J.

[0026] The lower surface of the pressing member 19 (the surface facing the first handle portion 11) is flat, and as will be described later, comes into contact with the upper surface (the surface on which the cover tape TT is attached) of the carrier tape CT held by the tape holding portion 15, and presses the lower surface side (base tape BT) of the carrier tape CT against the blade 17H ​​of the cutter 17. Hereinafter, this surface will be referred to as the "pressing surface 19M" (FIGS. 1 and 2).

[0027] The pressing member 19 is provided with two pin members 21 as protrusions that extend downward (toward the first handle portion 11). As shown in Fig. 1 and Fig. 2, the two pin members 21 are aligned in the longitudinal direction of the pressing member 19, sandwiching the swing shaft 18 therebetween, and are positioned so that when the ends (lower ends) of the pin members 21 come into contact with the contact surface 14M, as shown in Fig. 3, they sandwich the carrier tape CT held by the tape holding portion 15 in the width direction.

[0028] 7(a) and 7(b), a pin insertion hole 19H is formed at each end of the pressing member 19. Each pin insertion hole 19H communicates with a slit 19S extending from the end of the pressing member 19. Each of the two portions (two portions facing each other in the direction in which the oscillation shaft 18 extends) that form the slit 19S at each end of the pressing member 19 is provided with a through hole 19K that extends from one side surface to the other side surface, and a female screw 19J is formed on the inner surface of one of the through holes 19K.

[0029] 7(a) and 7(b), a pin fixing screw 19N with a male thread 19b is attached to each of two through holes 19K at both ends of the pressing member 19. The pin fixing screw 19N is inserted from the side of the two through holes 19K where the female thread 19J is not formed. As the male thread 19b and the female thread 19J are screwed into each other, the spacing between the slits 19S narrows, and the inner diameter of the pin insertion hole 19H becomes smaller. Therefore, by screwing the pin fixing screw 19N into the pin insertion hole 19H with the pin member 21 inserted therein, the pin member 21 can be fixed in the pin insertion hole 19H (i.e., to the pressing member 19).

[0030] The height HT (FIG. 6) from each end (end of pin member 21) to pressing surface 19M of two pin members 21 can be set to a desired value by adjusting the amount of protrusion from pressing surface 19M when fastening pin fixing screw 19N. In this embodiment, the height HT of two pin members 21 is adjusted so that they abut against abutment surface 14M when distance D (FIG. 6) between pressing portion 19 (specifically, pressing surface 19M) and blade 17H ​​of cutter 17 becomes a distance equivalent to the thickness of cover tape TT.

[0031] 2, the two pin fixing screws 19N described above, which are positioned side by side in the longitudinal direction of the second handle portion 12 on the flange FG side of the pressing member 19, are respectively positioned within two circular holes 12H formed in the flange FG. Therefore, the pressing member 19 can swing within a range in which the ends of the two pin fixing screws 19N can move within the circular holes 12H. Note that the two circular holes 12H also serve as insertion holes for tools such as screwdrivers when operating the pin fixing screws 19N.

[0032] When cutting the base tape BT of the carrier tape CT using the carrier tape cutting device 1 configured as above, first, the first handle portion 11 and the second handle portion 12 are opened (FIGS. 1 and 2). Then, the carrier tape CT with the cover tape TT facing up is held by the tape holding portion 15 provided on the first handle portion 11, thereby setting the carrier tape CT on the first handle portion 11.

[0033] To hold the carrier tape CT in the tape holding part 15, the carrier tape CT is oriented so as to extend substantially perpendicular to the longitudinal direction of the first handle part 11 and positioned within the notch part 11K of the first handle part 11, and then two feed holes KH of the carrier tape CT are fitted from above onto two holding pins 15P of the tape holding part 15 (FIG. 8(a)). As a result, the base tape BT of the carrier tape CT is positioned above the cutter 17, and the blade 17H ​​of the cutter 17 is in contact (or nearly in contact) with the base tape BT (FIG. 9; FIG. 9 is a cross-sectional view taken along the arrows V2-V2 in FIG. 8(a)).

[0034] As described above, in this embodiment, the carrier tape CT has a plurality of feed holes KH aligned along the longitudinal direction, and the tape holding part 15 is configured to have a plurality of holding pins 15P that hold the carrier tape CT by fitting some of the plurality of feed holes KH. Also, in this embodiment, the cutter 17 is provided on the first handle part 11, and has a blade 17H ​​at a position facing the base tape BT of the carrier tape CT when the carrier tape CT is held by the tape holding part 15.

[0035] The protruding length L (FIG. 9) of the carrier tape CT set on the first handle portion 11 from the cutter 17 is set to match the protruding length of the cover tape TT from the base tape BT that is to be obtained when the base tape BT is cut by the carrier tape cutting device 1. The protruding length of the cover tape TT is adjusted by changing the feed hole KH into which the holding pin 15P is fitted. In addition, the cutting position of the cover tape TT can be adjusted by changing the fixed position of the tape holding portion 15 relative to the holding portion base 14.

[0036] After the carrier tape CT is set on the first handle portion 11 according to the above procedure, the second handle portion 12 is rotated around the pivot axis 13J (arrow A shown in FIG. 8(a)) and the first handle portion 11 and the second handle portion 12 are operated in the direction of closing (FIG. 8(a) → FIG. 8(b)). As a result, the pressing member 19 provided on the second handle portion 12 approaches the blade 17H ​​of the cutter 17 provided on the first handle portion 11.

[0037] The pressing surface 19M of the pressing member 19, which has approached the blade 17H ​​of the cutter 17, comes into contact with the upper surface of the carrier tape CT (the surface on which the cover tape TT is attached). At this time, the pressing member 19 moves in an arcuate orbit centered on the pivot axis 13J, bringing a portion of the pressing member 19 into contact with the carrier tape CT (FIG. 10(a)). After this portion has come into contact, the pressing member 19 swings around the swing axis 18J (arrow B in FIG. 10(b)) to follow the shape of the upper surface of the carrier tape CT, bringing the pressing surface 19M into contact with the entire upper surface of the carrier tape CT in the width direction (FIG. 10(b)). Then, in this state, the base tape BT is pressed against the blade 17H ​​of the cutter 17 (FIG. 10(b) → FIG. 10(c)). At this time, the base tape BT is pressed against the cutter 17 with a uniform force in the width direction.

[0038] In this embodiment, the pressing member 19 is attached to the second handle portion 12 in a state in which it can swing freely around the swing axis 18J that extends approximately parallel to the pivot axis 13J, and when the first handle portion 11 and the second handle portion 12 are operated in the closing direction, it comes into contact with the carrier tape CT held by the tape holding portion 15 and presses the base tape BT against the cutter 17.

[0039] The pressing member 19 presses the base tape BT against the cutter 17 as described above, but when the ends (lower ends) of the two pin members 21 come into contact with the contact surface 14M, they can no longer approach the cutter 17 and are no longer able to press the base tape BT against the cutter 17. As described above, the heights HT of the two pin members 21 are adjusted so that they come into contact with the contact surface 14M when the distance D between the pressing surface 19M and the blade 17H ​​of the cutter 17 becomes a distance equivalent to the thickness of the cover tape TT. Therefore, when the two pin members 21 come into contact with the contact surface 14M (when the pressing member 19 can no longer come into contact with the cutter 17), the base tape BT of the carrier tape CT is cut, leaving the cover tape TT (FIGS. 10(c), 11, and 12(a)).

[0040] In this embodiment, the two pin members 21 provided on the pressing member 19 and the abutment surface 14M consisting of the upper surface of the holding portion base 14 provided on the first handle portion 11 act as a regulating means for regulating the pressing of the carrier tape CT by the pressing member 19 against the cutter 17 at the time when the base tape BT of the carrier tape CT pressed against the cutter 17 by the pressing member 19 is cut by the cutter 17.

[0041] As described above, the base tape BT is pressed against the cutter 17 by the pressing member 19 and cut, and at this time, the pressing member 19 swings around the swing axis 18J to follow the shape of the carrier tape CT, contacting the carrier tape CT and pressing the base tape BT against the cutter 17. As a result, the entire carrier tape CT is pressed against the blade 17H ​​of the cutter 17 with a uniform force in the width direction, and the base tape BT is cut extremely stably.

[0042] As described above, the cover tape TT of the carrier tape CT is attached to a portion of the width direction of the carrier tape CT, and therefore there are portions of the pressing surface 19M of the pressing member 19 that do not come into direct contact with the cover tape TT. Therefore, in the areas where the cover tape TT is not attached, the force with which the pressing member 19 presses the base tape BT against the cutter 17 is insufficient, and there is a risk that the base tape BT may not be completely cut. To address this issue, in this embodiment, as shown in Figures 1, 2, and 8(a), a contact member 22 is provided on the portion of the pressing surface 19M that does not come into direct contact with the cover tape TT.

[0043] The contact member 22 is a member that comes into contact with the area where the cover tape TT is not attached when the pressing member 19 is in contact with the top surface of the carrier tape CT (the surface on which the cover tape TT is attached), and plays a role in filling the gap between the pressing surface 19M and the top surface of the carrier tape CT when the pressing member 19 is in contact with the top surface of the carrier tape CT (FIG. 10(a) → FIG. 10(b)). For this reason, the contact member 22 has a height at least equivalent to the thickness of the cover tape TT and is made of an elastic material (e.g., resin). By providing the contact member 22 on the pressing member 19, the entire width of the carrier tape CT can be pressed against the cutter 17 (FIG. 10(c)). This ensures that only the base tape BT is cut.

[0044] Once the base tape BT has been cut as described above, the first handle portion 11 and the second handle portion 12 are operated in a direction that separates them from each other (opening direction) (Fig. 8(b) → Fig. 8(a)), and the carrier tape CT is then removed from the tape holding portion 15. Then, the tip portion BTS (Figs. 12(a) and (b)) of the cut base tape BT is removed from the carrier tape CT that has been removed from the tape holding portion 15. This results in the carrier tape CT being processed so that the tip TTS of the cover tape TT protrudes from the tip of the base tape BT (Fig. 12(b)).

[0045] As described above, the carrier tape cutting device 1 of this embodiment is based on a small, simply configured main body 10 including a first handle 11 and a second handle 12 that can be opened and closed by rotating about a pivot axis 13J. The first handle 11 is provided with a cutter 17, and the second handle 12 is provided with a pressing member 19. The pressing member 19 is attached to the second handle 12 so as to be able to swing about a swing axis 18J that extends substantially parallel to the pivot axis 13J. Therefore, when a portion of the pressing member 19 comes into contact with the carrier tape CT, the pressing member 19 swings about the swing axis 18J to follow the shape of the carrier tape CT, pressing the carrier tape CT against the cutter 17 with a uniform force in the width direction, thereby stably cutting the base tape BT. As described above, the carrier tape cutting device 1 of this embodiment can stably cut the base tape BT despite its small size and simple configuration.

[0046] While the present invention has been described above in terms of an embodiment, it is not limited to the above, and various modifications are possible. For example, in the above embodiment, the regulating means is configured to include pin members 21 as two protrusions provided on the pressing member 19 and abutment surfaces 14M provided on the first handle portion 11 and abutting against the two pin members 21. However, the regulating means may be configured to regulate the pressing of the carrier tape CT by the pressing member 19 against the cutter 17 when the base tape BT of the carrier tape CT pressed against the cutter 17 by the pressing member 19 is cut by the cutter 17. Therefore, the two protrusions may be provided on the first handle portion 11, and the abutment surface that abuts against them may be provided on the pressing member 19.

[0047] Furthermore, the tape holding portion 15 need only hold the carrier tape CT in a position extending approximately perpendicular to the first handle portion 11, and is not limited to a configuration having a plurality of holding pins 15P that are inserted into a plurality of feed holes KH that form a row of feed holes KH in the carrier tape CT, as shown in the above-mentioned embodiment.
