[0051] Hereinafter, embodiments will be described in detail with appropriate reference to the accompanying drawings. However, sometimes unnecessary detailed descriptions are omitted. For example, detailed descriptions of known matters and repetitive descriptions of substantially the same structures are sometimes omitted. This is to avoid making the following description unnecessarily lengthy and to make it easier for those skilled in the art to understand.

[0052] It should be noted that the inventors have provided the accompanying drawings and the following description in order to facilitate a full understanding of this disclosure by those skilled in the art, but it is not intended to limit the subject matter of the technical solution described by these drawings and descriptions.

[0053] Hereinafter, a belt cutting device according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0054] Figure 1 This is a perspective view of a cutting device according to one embodiment of this disclosure. Additionally, Figure 2 This is a side view of the cutting device. It should be noted that, for ease of understanding, an XYZ orthogonal coordinate system is shown in the drawings. The X-axis represents the width direction of the component supply belt (belt width direction), the Y-axis represents the length direction (belt length direction), and the Z-axis represents the thickness direction (belt thickness direction). This XYZ coordinate system is not a coordinate system limiting the embodiments of this disclosure.

[0055] like Figure 1 and Figure 2 As shown, the belt cutting device 10 of this embodiment is configured to cut the component supply belt 100. Before describing the structure of this belt cutting device 10, firstly, refer to... Figures 3A-3C The cutting of the component supply belt by the belt cutting device 10 will be described.

[0056] Figure 3A This is a perspective view of a component supply belt cut by a cutting device according to an embodiment of this disclosure. Additionally, Figure 3B This is a perspective view of a component supply belt after both the carrier belt and the cover belt have been cut by a belt cutting device. Furthermore, Figure 3C This is a perspective view of a component being supplied with a belt after the carrier belt has been cut by a belt cutting device.

[0057] like Figure 3A As shown, the component supply belt 100 consists of a carrier belt 102 and a cover belt 104 attached to the carrier belt 102.

[0058] Specifically, the carrier belt 102 is made of, for example, resin or paper material, and has a first surface 102a and a second surface 102b on its opposite side. A plurality of component recesses 102c, accommodating components (not shown), are formed on the first surface 102a. The plurality of component recesses 102c are arranged in the belt length direction (Y-axis direction) of the carrier belt 102. Additionally, the carrier belt 102 has a plurality of feed holes 102d arranged in the belt length direction and engaging with a sprocket of a component supply device.

[0059] The cover tape 104 is made of, for example, resin material and is attached to the first surface 102a of the carrier tape 102 in such a way as to cover the multiple component grooves 102c.

[0060] In this embodiment, such as Figure 3B As shown, the cutting device 10 is configured to cut the front end portion of the component supply belt 100, namely the front end portion 102e of the carrier belt 102, and the front end portion 104a of the cover belt 104 attached to that portion. This is to create a new front end 100a on the component supply belt 100.

[0061] Furthermore, in this embodiment, such as Figure 3C As shown, in the component supply belt 100 with a new front end 100a, the belt cutting device 10 is configured to cut the new front end side portion 102f of the carrier belt 102 without cutting the cover belt 104. As a result, the new front end side portion 104b of the cover belt 104 extends along the belt length direction (Y-axis direction) beyond the new front end 102g of the carrier belt 102.

[0062] It should be noted that, in Figures 3A-3C In the component supply belt 100 shown, the second surface 102b of the carrier belt 102 is formed by a plane. However, as Figure 2 As shown, the tape cutting device 10 of this embodiment is configured to also be able to cut the component supply tape 100' having a plurality of embossed portions 102h' arranged along the tape length direction (Y-axis direction) on the second surface 102b' of the carrier tape 102'.

[0063] like Figure 1 and Figure 2 As shown, the belt cutting device 10 of this embodiment has a cutting unit 20 for cutting the component supply belt 100.

[0064] Figure 4 This is a 3D view of the cut-off unit. Additionally, Figure 5 This is an exploded perspective view of the cut-off unit from the front. Furthermore, Figure 6 This is an exploded 3D view of the cut-off unit.

[0065] like Figures 4-6As shown, in this embodiment, the cutting unit 20 is generally composed of three parts. Specifically, the cutting unit 20 includes a blade support block (blade support member) 22, a pressing head (pressing member) 24, and a retainer (retaining member) 26.

[0066] The blade support block 22 and the belt pressing head 24 are arranged opposite each other in the belt thickness direction (Z-axis direction), details of which will be described later, but they may approach or move away from each other in the belt thickness direction. The belt retainer 26 will be described in detail later, but it is configured to be movable relative to the blade support block 22 in the belt thickness direction. First, the details of these three components will be explained.

[0067] Figure 7 This is an exploded perspective view of the blade support block 22.

[0068] In this embodiment, the blade support block 22 in the cutting unit 20 is a generally cuboid-shaped block that supports the first blade 30 and the second blade 32. The first blade 30 is as follows: Figure 3B The blade shown is used to cut both the carrier tape 102 and the cover tape 104. The second blade 32 on the other side is as follows... Figure 3C The blade shown is used to cut only the carrier tape 102.

[0069] In this embodiment, the first blade 30 and the second blade 32 are identical square blades, each with a straight blade tip 30a and blade tip 32a. Furthermore, the first blade 30 and the second blade 32 are supported parallel to each other on the blade support block 22 when viewed from the belt thickness direction (Z-axis direction). However, the first blade 30 and the second blade 32 are positioned on the blade support block 22 in different orientations and at different locations in the belt length direction (Y-axis direction). The reasons for this will be explained later.

[0070] Furthermore, the first blade 30 is supported (fixed) to the blade support block 22 in a non-movable manner. Specifically, in this embodiment, the first blade 30 has a through hole 30b. A fixing screw 36 passing through the through hole 30b and the plate washer 34 engages with a threaded hole formed in the blade support block 22, thereby fixing the first blade 30 to the blade support block 22.

[0071] Unlike the first blade 30, in this embodiment, the second blade 32 is supported on the blade support block 22 in a movable manner, particularly in the thickness direction (Z-axis direction). This is because, unlike the first blade 30, which cuts both the carrier tape 102 and the cover tape 104, the second blade 32 only cuts the carrier tape 102. That is, it is necessary to adjust the position of the second blade 32 relative to the blade support block 22 in the thickness direction so that the cover tape 104 is not cut while only the carrier tape 102 is cut.

[0072] Specifically, as a component for adjusting the position of the second blade 32, a force-applying member 38 is provided in the blade support block 22 to apply force to the second blade 32 toward the pressing head 24. It should be noted that, in this embodiment, the force-applying member 38 is a compression spring.

[0073] In this embodiment, the force-applying member 38 applies force to 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 tip 32a, and is provided on the blade support block 22 in a manner that allows it to move in the thickness direction (Z-axis direction). Specifically, the blade receiving member 40 has an elongated hole 40a in the thickness direction, and is supported by a guide screw 42 passing through this hole 40a, allowing it to move in the thickness direction. It should be noted that the guide screw 42 is a screw having a head, a guide pin extending from the head, and an externally threaded portion provided at the front end of the guide pin. By using such a blade receiving member 40, the force-applying member 38 can apply force to the thin second blade 32.

[0074] Furthermore, in this embodiment, after the position of the second blade 32 relative to the blade support block 22 is adjusted, the second blade 32 is fixed to the blade support block 22 by a blade fixing member to maintain this adjusted position. In this embodiment, the blade fixing member is a fixing screw 44. The fixing screw 44 passes through the through hole 32c of the second blade 32 and the plate washer 46, and engages with the threaded hole formed in the blade support block 22. In addition, the diameter of the through hole 32c of the second blade 32 is sufficiently larger than the diameter of the threaded portion of the fixing screw 44.

[0075] Therefore, the second blade 32 is fixed to the blade support block 22 by tightening the fixing screw 44. On the other hand, by loosening the fixing screw 44, the second blade 32 can move in the thickness direction (Z-axis direction). That is, the second blade 32 is supported on the blade support block 22 in a manner that allows it to move in the thickness direction.

[0076] The method for adjusting the position of the second blade 32 relative to the blade support block 22 which uses the aforementioned force-applying member 38, blade receiving member 40, and fixing screw 44 will be described later.

[0077] like Figures 4-6 As shown, the pressing head 24 is positioned opposite the blade support block 22, that is, opposite the blade tips 30a and 32a of the first blade 30 and the second blade 32 disposed on the blade support block 22, in the belt thickness direction (Z-axis direction). The component supply belt 100 is positioned between the pressing head 24 and the blade tips 30a and 32a of the first blade 30 and the second blade 32, with the cover belt 104 opposite to the pressing head 24. In this state, the blade support block 22 and the pressing head 24 approach each other, thereby cutting the component supply belt 100 by the first blade 30 and the second blade 32.

[0078] It should be noted that, in this embodiment, the approach between the blade support block 22 and the pressing head 24 is performed manually by the operator.

[0079] Therefore, such as Figure 1 and Figure 2 As shown, the belt cutting device 10 includes: a first arm 12A rotatably connected to a blade support block 22; a second arm 12B rotatably connected to a belt pressing head 24; a first operating lever 14A and a second operating lever 14B for operation by a user; a first link 16A connecting the first arm 12A and the second operating lever 14B; and a second link 16B connecting the second arm 12B and the first operating lever 14A. The central portions of the first link 16A and the second link 16B are connected in a manner that allows them to rotate relative to each other with a rotation centerline extending along the belt length direction (Y-axis direction) as the center, thus forming an X-linkage mechanism.

[0080] A blade support block 22 is connected to the front end of the first arm 12A. The blade support block 22 is rotatable about a rotation center line extending along the belt length direction (Y-axis direction). The first arm 12A is connected to one end of the first link 16A of the X-linkage mechanism in such a way that it can rotate about the rotation center line extending along the belt length direction and move in the belt width direction (X-axis direction).

[0081] A pressing head 24 is connected to the front end of the second arm 12B. The pressing head 24 is rotatable about a rotation center line extending along the belt length direction (Y-axis direction). The second arm 12B is connected to one end of the second link 16B of the X-link mechanism in such a way that it can rotate about the rotation center line extending along the belt length direction and move in the belt width direction (X-axis direction).

[0082] The first operating lever 14A is connected to the other end of the second link 16B in a manner that allows it to rotate around a rotation centerline extending along the belt length direction (Y-axis direction).

[0083] The second operating lever 14B is connected to the other end of the first link 16A in a manner that allows it to rotate around a rotation centerline extending along the belt length direction (Y-axis direction).

[0084] Based on the connection between the first arm 12A and the second arm 12B and the first operating lever 14A and the second operating lever 14B, when the first operating lever 14A and the second operating lever 14B approach each other through the operator's operation, the first arm 12A and the second arm 12B also approach each other. As a result, the blade support block 22 and the pressing head 24 approach each other.

[0085] like Figures 4-6 As shown, in order to position the blade support block 22 and the belt pressing head 24 relative to each other in the belt width direction (X-axis direction) and the belt length direction (Y-axis direction), the belt pressing head 24 includes a guide rod 48. The guide rod 48 extends toward the blade support block 22 in the belt thickness direction (Z-axis direction) and engages with a guide hole 22a provided in the blade support block 22. Through the engagement of the guide rod 48 with the guide hole 22a, the blade support block 22 and the belt pressing head 24 move parallel to each other and approach each other.

[0086] Furthermore, as a component of positioning, the blade support block 22 has a plurality of positioning pins 50. The plurality of positioning pins 50 extend toward the belt pressing head 24 in the belt thickness direction (Z-axis direction).

[0087] Figure 8 This is a perspective view showing the pressing surface of the cutting unit with a pressing head.

[0088] Figure 8 As shown, the belt pressing head 24 has multiple positioning holes 24a on its surface opposite to the blade support block 22, which engage with multiple positioning pins 50 provided on the blade support block 22. These positioning pins 50 and positioning holes 24a engage when the blade support block 22 and the belt pressing head 24 are somewhat close, for example, before the first blade 30 of the blade support block 22 begins to cut the component supply belt 100.

[0089] like Figure 8As shown, the pressing head 24 has a pressing surface 24b opposite to the tips 30a and 32a of the first blade 30 and the second blade 32 supported on the blade support block 22. The pressing surface 24b contacts the cover tape 104 of the component supply tape 100. Thus, when the first blade 30 and the second blade 32 of the blade support block 22 cut the component supply tape 100 from the second surface 102b of the carrier tape 102, the pressing surface 24b supports the component supply tape 100.

[0090] It should be noted that the pressing head 24 contacts the cover tape 104 on its 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 pressing head 24 is in contact with the cover tape 104, a gap is created between the portion of the carrier tape 102 not covered by the first surface 102a of the cover tape 104 and the pressing head 24. The pressing head 24 has a gap-filling portion to fill this gap.

[0091] In this embodiment, a resin plate 52 is disposed on the pressing head 24 as a gap filling part. The resin plate 52 has a contact surface 52a, which contacts the carrier belt 102 when the pressing surface 24b of the pressing head 24 is in contact with the cover belt 104. It should be noted that the function of the resin plate 52 will be described later.

[0092] Furthermore, details of the pressing head 24 will be described later, but it has a recess, such as a groove 24c, for receiving the tip 30a of the first blade 30 after the component is cut by the belt 100.

[0093] like Figures 4-6 As shown, the belt retainer 26 is a component used to hold the component supply belt 100, thereby maintaining the component supply belt 100 between the blade support block 22 and the belt pressing head 24.

[0094] Figure 9 This is a top view of the belt holder in the state of holding the component supply belt.

[0095] like Figure 9 As shown, the belt retainer 26 includes a first belt retaining surface 26a and a second belt retaining surface 26b, which are mounted on the end of the belt press head 24 side to retain the component supply belt 100. The first belt retaining surface 26a and the second belt retaining surface 26b are arranged at intervals in the belt length direction (Y-axis direction). The tips 30a and 32a of the first blade 30 and the second blade 32 of the blade support block 22 pass between the first belt retaining surface 26a and the second belt retaining surface 26b.

[0096] It should be noted that, in this embodiment, as Figure 5 and Figure 6 As shown, the first tape holding surface 26a is divided into two parts in the tape width direction (X-axis direction). Similarly, the second tape holding surface 26b is also divided into two parts. This is because, as... Figure 2 As shown, the tape cutting device 10 of this embodiment also corresponds to a component supply tape 100' having a plurality of embossed portions 102h' arranged along the tape length direction (Y-axis direction) on the second surface 102b' of the carrier tape 102'. That is, the recessed clearance portion 26c for avoiding contact with the embossed portion 102h' is formed by dividing it into two parts in the tape width direction by the first tape holding surface 26a and the second tape holding surface 26b respectively. When the tape cutting device 10 does not correspond to a component supply tape having embossed portions, the first tape holding surface 26a and the second tape holding surface 26b may not be divided into two parts respectively, but may be continuous surfaces.

[0097] In addition, such as Figures 4-6 As shown, one of the two parts of the first belt holding surface 26a is provided with a plurality of positioning pins 54 extending along the belt thickness direction (Z-axis direction) and engaging with the feed hole 102d of the carrier belt 102. By engaging the positioning pins 54 with the feed hole 102d, the component supply belt 100 is positioned relative to the belt holder 26 in the belt width direction (X-axis direction) and the belt length direction (Y-axis direction).

[0098] like Figures 4-6 As shown, in this embodiment, the tape holder 26 is a square bracket-shaped structure when viewed from the tape thickness direction (Z-axis direction), and is disposed on the blade support block 22 such that it at least partially covers the blade support block 22 when viewed from the tape thickness direction. That is, the tape holder 26 is disposed on the blade support block 22 such that it at least partially surrounds the first blade 30 and the second blade 32 supported on the blade support block 22 when viewed from the tape thickness direction.

[0099] Furthermore, the belt retainer 26 is provided on the blade support block 22 in a manner that allows it to move in the belt thickness direction (Z-axis direction). Specifically, the belt retainer 26 has an elongated guide hole 26d formed in the belt thickness direction (Z-axis direction). A guide screw 56, passing through the guide hole 26d and engaging with the internal threaded hole of the blade support block 22, is provided on the blade support block 22. Thus, the belt retainer 26 is held on the blade support block 22 in a manner that allows it to move in the belt thickness direction (Z-axis direction).

[0100] Furthermore, in this embodiment, the belt retainer 26 is suspended from the blade support block 22 via a tension spring 58. A suspension pin 60 is provided on the portion of the blade support block 22 on the side of the belt pressing head 24 for hooking one end of the tension spring 58. On the other hand, a hook portion 26e is provided on the end of the belt retainer 26 away from the belt pressing head 24 for hooking the other end of the tension spring 58.

[0101] The tension spring 58 ensures that the belt retainer 26 maintains an overlap with the tips 30a and 32a of the first blade 30 and the second blade 32 when viewed from the belt width direction (X-axis direction) and the belt length direction (Y-axis direction). As a result, the belt retainer 26 functions as a cover member protecting the tips 30a and 32a of the first blade 30 and the second blade 32, and preventing contact between the tips 30a and 32a and the operator. Further details will be described later, but during the movement of the blade support block 22 toward the belt pressing head 24, when the belt retainer 26 contacts the belt pressing head 24, the belt retainer 26 moves relative to the blade support block 22, and when viewed from the belt width direction and the belt length direction, the tips 30a and 32a of the first blade 30 and the second blade 32 protrude from the belt retainer 26.

[0102] This concludes the description of the structure of the cutting unit in the cutting device 10. The operation of the cutting unit will now be explained, along with further details on the constituent elements of the cutting unit.

[0103] Figure 10A and Figure 10B These are side and sectional views of the cutting unit with the component supply belt assembled.

[0104] like Figure 10A and Figure 10B As shown, the component supply belt 100 is assembled (placed) on the first belt holding surface 26a and the second belt holding surface 26b of the belt holder 26 with the blade support block 22 and the belt pressing head 24 far apart. Furthermore, the component supply belt 100 is assembled with the cover belt 104 facing the belt pressing surface 24b of the belt pressing head 24. It should be noted that... Figure 10A and Figure 10B The blade support block 22 is shown in the state where it is furthest from the pressing head 24.

[0105] like Figure 10AAs shown, in this embodiment, the tip 30a of the first blade 30 is positioned closer to the belt pressing surface 24b of the belt pressing head 24 than the tip 32a of the second blade 32. Therefore, after the tip 30a of the first blade 30 cuts both the carrier belt 102 and the cover belt 104, the tip 32a of the second blade 32 can begin cutting the carrier belt 102. As a result, cutting resistance is reduced compared to the case where the tips 30a and 32a of the first and second blades 30 and 32a cut the carrier belt 102 simultaneously. In this embodiment, the operator can cut the component supply belt 100 with less force.

[0106] Furthermore, the tip 30a of the first blade 30 is not parallel to the pressing surface 24b of the pressing head 24. In this embodiment, the tip 30a is a straight line inclined relative to the pressing surface 24b when viewed from the length direction (Y-axis direction). Therefore, compared to the case where the tip 30a is parallel to the pressing surface 24b of the pressing head 24, the cutting resistance can be reduced. The reason is that in the parallel case, the cutting resistance is high in order to simultaneously cut the entire width direction (X-axis direction) of the carrier belt 102 with the tip 30a. It should be noted that the tip 30a of the first blade 30 is not limited to a straight line; for example, it can also be arc-shaped.

[0107] In contrast, unlike the tip 30a of the first blade 30, the tip 32a of the second blade 32 is parallel to the pressing surface 24b of the pressing head 24, that is, parallel to the cover tape 104 that contacts the pressing surface 24b. This is to reliably cut the carrier tape 102 without cutting the cover tape 104.

[0108] Moreover, such as Figure 10A and Figure 10B As shown, the tips 30a and 32a of the first blade 30 and the second blade 32 overlap with the belt retainer 26 when viewed from the belt width direction (X-axis direction) and the belt length direction (Y-axis direction). That is, the tips 30a and 32a of the first blade 30 and the second blade 32 are located on the opposite side of the belt pressing head 24 relative to the first belt holding surface 26a and the second belt holding surface 26b of the belt retainer 26. As a result, when the component supply belt 100 is assembled onto the first belt holding surface 26a and the second belt holding surface 26b of the belt retainer 26, it is possible to prevent the operator's fingers from contacting the tips 30a and 32a.

[0109] It should be noted that a hook 62 is provided on the pressing head 24 so that, as Figure 10A and Figure 10BWhen the blade support block 22 is furthest from the belt pressing head 24, as shown, the belt retainer 26 maintains an overlap with the tips 30a and 32a of the first blade 30 and the second blade 32. The hook 62 is engaged with the belt retainer 26, thereby restricting the belt retainer 26 from moving away from the belt pressing head 24. Thus, there is no situation where the belt retainer 26 moves, causing the tips 30a and 32a of the first blade 30 and the second blade 32 to protrude from the belt retainer 26, thereby preventing contact between the operator's fingers and the tips 30a and 32a.

[0110] In such Figure 10A and Figure 10B After the component supply belt 100 is assembled into the cutting unit 20 as shown, the blade support block 22 and the belt pressing head 24 approach each other. In this embodiment, the blade support block 22 and the belt pressing head 24 approach each other by the operator's operation of bringing the first operating lever 14A and the second operating lever 14B closer together.

[0111] Figure 11A and Figure 11B These are side and sectional views of the cutting unit with the component supply belt clamped in the specified state.

[0112] When the blade support block 22 and the pressing head 24 approach each other, as Figure 11A and Figure 11B As shown, the belt retainer 26, which is provided on the blade support block 22, contacts the belt pressing head 24. In this embodiment, the belt retainer 26 contacts the belt pressing head 24 via the component supply belt 100 it holds. Thus, the component supply belt 100 is clamped (held) by the belt pressing head 24 and the belt retainer 26.

[0113] like Figure 11A As shown, with the component supply belt 100 clamped, the pressing surface 24b of the pressing head 24 contacts the cover belt 104. Additionally, the resin plate 52 contacts the portion of the carrier belt 102 not covered with the cover belt 104. Using this resin plate 52, the component supply belt 100 is clamped in a state where it cannot be displaced towards the pressing head 24. The effect of this resin plate 52 will be explained in detail.

[0114] Figure 12A The image shows the carrier tape after it has been cut by the second blade, with resin plate 52 present. Additionally, Figure 12B The carrier tape after being cut by the second blade is shown when the resin plate 52 is not present.

[0115] As described above, the second blade 32 only cuts the carrier tape 102. At this time, in the absence of the resin plate 52, it is possible that cut residue of the carrier tape 102 will be generated.

[0116] Specifically, the portion of the carrier tape 102 with the cover tape 104 attached contacts the tape pressing surface 24b of the tape pressing head 24 via the cover tape 104. Therefore, even when pressed by the second blade 32, this portion cannot move away from the tape pressing surface 24b. Consequently, the portion of the carrier tape 102 with the cover tape 104 attached is cut off by the tip 32a of the second blade 32.

[0117] In contrast, such as Figure 12B As shown, a space S is formed between the portion of the carrier tape 102 without the cover tape 104 and the tape pressing head 24. Therefore, this portion is pressed by the second blade 32 and can be pushed away towards the tape pressing surface 24b. As a result, it is possible for cutting residue to be generated on the portion of the carrier tape 102 without the cover tape 104.

[0118] As a countermeasure, such as Figure 12A As shown, a resin plate 52 is provided to fill the gap between the portion of the carrier tape 102 without the cover tape 104 and the tape pressing head 24. Using this resin plate 52, the portion of the carrier tape 102 without the cover tape 104 cannot be pushed towards the tape pressing head 24 even when pressed by the second blade 32. As a result, the portion of the carrier tape 102 without the cover tape 104 is cut off by the tip 32a of the second blade 32.

[0119] In addition, such as Figure 10A As shown, preferably, the distance D from the pressing surface 24b of the 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. 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 will deform. This further reduces the possibility of cutting residue on the portion of the carrier tape 102 where the cover tape 104 is not attached.

[0120] Moreover, such as Figure 9 As shown, the contact surface 52a of the preferred resin plate 52 extends beyond the end of the carrier tape 102 in the width direction (X-axis direction). This more reliably prevents the portion of the carrier tape 102 without the cover tape 104 from being pressed and avoided by the second blade 32. Consequently, the possibility of cutting residue on the portion of the carrier tape 102 without the cover tape 104 is further reduced.

[0121] It should be noted that the gap-filling component that fills the gap between the portion of the carrier tape 102 not covered with the cover tape 104 and the tape pressing head 24 can be any component that does not damage the tip 32a of the second blade 32, and is not limited to a resin board. In addition, the gap-filling component may not be a part other than the tape pressing head 24, but may be provided as part of the tape pressing head 24 (as a gap-filling part).

[0122] In such Figure 11A and Figure 11B As shown, after the belt retainer 26 contacts the belt pressing head 24 via the component supply belt 100, the blade support block 22 moves relative to the belt retainer 26 and thereby toward the belt pressing head 24. As a result, the tip 30a of the first blade 30 supported on the blade support block 22 begins to cut the component supply belt 100.

[0123] Figure 13A and Figure 13B These are side and sectional views of the cutting unit in the state where the first blade begins to cut the component supply belt.

[0124] like Figure 13A and Figure 13B As shown, the tip 30a of the first blade 30 begins to cut the component supply belt 100, which is clamped by the belt pressing head 24 and the belt holder 26. At this time, the tip 30a of the first blade 30 begins to cut from one end of the component supply belt 100 (both the carrier belt 102 and the cover belt 104) in the belt width direction (X-axis direction). It should be noted that the tip 30a, which cuts through the component supply belt 100, is received in the groove 24c of the belt pressing head 24. On the other hand, the tip 32a of the second blade 32 does not reach the carrier belt 102 and does not begin to cut.

[0125] As the blade support block 22 approaches the belt pressing head 24 further, the tip 30a of the first blade 30 further cuts the component supply belt 100 (both the carrier belt 102 and the cover belt 104).

[0126] Figure 14A and Figure 14B The first blade 30 is a side view and a cross-sectional view of the cutting unit in the middle of the cutting component supply belt 100.

[0127] Figure 14A and Figure 14B The diagram shows the first blade 30's tip 30a cutting more than half of the component supply belt 100. On the other hand, the second blade 32's tip 32a has not reached the carrier belt 102 and has not yet begun cutting.

[0128] As the blade support block 22 approaches the pressing head 24 further, the tip 30a of the first blade 30 completely cuts the component supply belt 100 (both the carrier belt 102 and the cover belt 104). As a result, as Figure 3B As shown, a new front end 100a is made on the component supply belt 100. Then, the tip 32a of the second blade 32 begins to cut the carrier belt 102.

[0129] Figure 15A and Figure 15BThese are side and sectional views of the cutting unit in the state where the second blade has completed cutting the carrier tape.

[0130] like Figure 15A and Figure 15B As shown, the tip 32a of the second blade 32 cuts the carrier tape 102 when the blade support block 22 is closest to the tape pressing head 24. That is, when the blade support block 22 is closest to the tape pressing head 24, the tip 32a of the second blade 32 is positioned opposite the tape pressing surface 24b of the tape pressing head 24, separated by a distance approximately equal to the thickness of the cover tape 104. Approximately equal distance means that if the thickness of the cover tape 104 is t, the distance between the tip 32a of the second blade 32 and the tape pressing surface 24b is t × 0.9 or more and t less.

[0131] Thus, with the blade support block 22 and the pressing head 24 closest together, the position of the tip of the second blade 32 relative to the blade support block 22 is adjusted so that the tip 32a is positioned opposite the pressing surface 24b of the pressing head 24, separated by a distance approximately equal to the thickness of the cover strip 104. The method for adjusting this position will be explained.

[0132] Figures 16A-16C This diagram illustrates the process of adjusting the position of the tip of the second blade.

[0133] like Figure 16A As shown, when adjusting the tip position of the second blade 32, the belt retainer 26 is removed from the blade support block 22. Additionally, a metal pad SP with the same thickness t as the cover belt 104 of the component supply belt 100 is prepared and positioned between the belt pressing surface 24b of the pressing head 24 and the tip 32a of the second blade 32.

[0134] First, in order to make the second blade 32 movable relative to the blade support block 22, the fixing screw 44 is loosened. As a result, the force-applying member 38 applies force to the second blade 32 via the blade receiving member 40 toward the pressing head 24.

[0135] Next, as Figure 16B As shown, the blade support block 22 and the belt pressing head 24 are in their closest possible position. Consequently, the tip 32a of the second blade 32 contacts the pad SP. This contact causes the second blade 32 to overcome the force of the force-applying member 38 and move away from the belt pressing head 24.

[0136] Then, with the tip 32a of the second blade 32 in contact with the pad SP, the fixing screw 44 is tightened. Thus, as... Figure 16CAs shown, the second blade 32 is fixed to the blade support block 22 such that, with the blade support block 22 and the pressing head 24 in their closest position, the distance between the tip 32a of the second blade 32 and the pressing surface 24b is approximately the same as the thickness t of the cover strip 104. It is desirable that this distance is the same as the thickness t of the cover strip 104, but it can also be greater than t × 0.9 and less than t.

[0137] By adjusting the position of the second blade 32 relative to the blade support block 22, such as Figure 15B As shown, the tip 32a of the second blade 32 is capable of cutting only the carrier belt 102 without cutting the cover belt 104.

[0138] According to this embodiment as described above, in a component supply belt consisting of a carrier belt and a cover belt attached to the carrier belt, only the front end portion of the carrier belt can be cut off. That is, the front end portion of the carrier belt can be cut off more reliably without leaving any carrier belt cutting residue.

[0139] The above embodiments have been described, but the embodiments disclosed herein are not limited to the above embodiments.

[0140] For example, in the above-described embodiment, in the belt cutting device 10, the blade support block 22 and the belt pressing head 24 are brought closer together by the operator's manual operation. However, the embodiments of this disclosure are not limited to this. The blade support block 22 and the belt pressing head 24 may also be driven by a drive source such as a cylinder.

[0141] Furthermore, in the above-described implementation scenarios, such as Figure 3B As shown, in order to create a new front end 100a on the component supply belt 100, the belt cutting device 10 has a first blade 30 that cuts both the carrier belt 102 and the cover belt 104. However, when it is not necessary to create a new front end on the component supply belt 100, the first blade 30 may be omitted.

[0142] Furthermore, in the above-described embodiment, the component supply belt 100 is held by a belt retainer 26 mounted on the blade support block 22. However, the embodiments of this disclosure are not limited to this. The component supply belt 100 may also be fixed to the belt pressing head 24 while the cover belt 104 is in contact with the belt pressing surface 24b.

[0143] That is, the tape cutting device of the present disclosure is broadly defined as a tape cutting device for cutting a component supply tape including a carrier tape and a cover tape attached to the carrier tape, and has: a tape pressing member having a tape pressing surface that contacts the cover tape; and a blade having a blade tip facing the tape pressing surface of the tape pressing member and moving toward the tape pressing member, the tape pressing member having a gap filling portion that fills the gap between the portion of the carrier tape not attached to the cover tape and the tape pressing member when the tape pressing surface is in contact with the cover tape.

[0144] As described above, the above embodiments have been illustrated as examples of the technology in this disclosure. For this purpose, accompanying drawings and detailed descriptions have been provided. Therefore, the components described in the drawings and detailed descriptions include not only those necessary to solve the problem, but also those not necessary to solve the problem, for the purpose of illustrating the above technology. Therefore, one should not directly assume that these non-essential components are necessary simply because they are described in the drawings and detailed descriptions.

[0145] Furthermore, the above embodiments are used to illustrate the technology in this disclosure, and therefore various changes, substitutions, additions, omissions, etc., can be made within the scope of the technical solution or its equivalents.
