A portion of one side of the cover tape 306 in the tape width direction in the conveyed carrier tape 300 is continuously peeled off from the base tape 304 .

FIG. 3A is an exploded view of the cover tape peeling mechanism 110 , and FIG. 3B is a perspective view of the cover tape peeling mechanism 110 . 4A is a diagram of the cover tape peeling mechanism 110 just before partially peeling the cover tape 306 in the carrier tape 300 conveyed in the tape conveying direction A from the base tape 304 as viewed from above. 4B is a top view of the cover tape peeling mechanism 110 that is partially peeling the cover tape 306 in the carrier tape 300 conveyed along the tape conveying direction A from the base tape 304 .

As shown in FIGS. 3A and 3B , the cover tape peeling mechanism 110 has: a peeling portion 112 for partially peeling the cover tape 306 from the base tape 304 of the carrier tape 300; The folded portion 114 is folded toward the transfer hole 308 side as shown in FIG. 4B .

The peeling portion 112 of the cover tape peeling mechanism 110 is formed by forming a blade portion 112 a for peeling the cover tape 306 from the base tape 304 on a long metal plate. The blade portion 112a has a cutting edge 112b for peeling the cover tape 306 from the base tape 304, a rake face 112c that pushes up the peeled cover tape 306 so as to be separated from the base tape 304, and Enters the tip front end 112d between the cover tape 306 and the base tape 304 .

The folded-back portion 114 of the cover tape peeling mechanism 110 is attached to an upper surface 112 e on the upper side of the peeling portion 112 . In addition, the folded portion 114 has a concave conical curved surface 114 a that guides the portion of the cover tape 306 peeled off by the peeling portion 112 so that the peeled portion of the cover tape 306 is folded back toward the transfer hole 308 b side of the carrier tape 300 . . The conical curved surface 114a extends from the upper surface 112e of the peeling part 112, and is curved in a concave shape to protrude (overhang).

As shown in FIG. 4A , the cover tape peeling mechanism 110 is designed to enable the blade tip front end 112d of the peeling portion 112 to enter the unbonded portion between the cover tape 306 and the base tape 304 (that is, the two ends on the tape width direction). The part between the adhesives 310a, 310b) is provided on the main body 102 of the component supply device 100 . In addition, the concave conical curved surface 114 a of the folded portion 114 opens toward the transfer hole 308 side of the carrier tape 300 .

When the carrier tape 300 is conveyed along the tape conveying direction A toward the component supply position Q by the plurality of sprockets 104a to 104c, the knife edge front end 112d of the peeling part 112 of the cover tape peeling mechanism 110 moves from the front end surface 312 of the carrier tape 300 The side enters between the cover tape 306 and the base tape 304 .

When the carrier tape 300 in a state in which the blade tip 112d of the peeling portion 112 of the cover tape peeling mechanism 110 has entered between the cover tape 306 and the base tape 304 is conveyed further toward the component supply position Q along the tape conveying direction A, the peeling The blade edge 112 b of the portion 12 starts to continuously peel off a part of the cover tape 306 (one side portion in the tape width direction) from the base tape 304 .

Specifically, the blade edge 112b of the peeling portion 112 starts to continuously peel off the portion of the cover tape 306 from the base tape 304 on the side away from the conveyance hole 202b in the tape width direction, that is, the side end surface 314a side of the carrier tape 300 . The portion on the side end surface 314a side of the cover tape 306 peeled off by the knife edge 112b is guided by the rake surface 112c toward the curved surface 114a of the turnback portion 114 as the carrier tape 200 is conveyed.

In addition, as the carrier tape 200 is conveyed along the tape conveyance direction A toward the component supply position Q, as shown in FIG. It is folded back toward the transmission hole 308 side (the side end surface 314b side) under the action of the curved surface l14a.

Specifically, the portion of the cover tape 306 peeled from the base tape 304 on the side end surface 314a side is guided by the conical curved surface 114a, whereby the portion of the cover tape 306 on the side end surface 314a side is folded back toward the transfer hole 308 side.

With this cover tape peeling mechanism 110 , the carrier tape 300 in a state where the cover tape 306 is partially peeled off from the base tape 304 to sequentially expose the components housed in the storage portions 302 of the carrier tape 300 can be delivered to the component supply position Q. send. As a result, the nozzles 202 of the transfer head 200 of the component mounting apparatus can sequentially attract and take out the components respectively accommodated in the plurality of storage portions 302 of the base tape 304 at the component supply position Q.

So far, the components supplying apparatus which is the premise of the cover tape peeling apparatus of this invention was demonstrated taking the components supplying apparatus 100 shown in FIGS. 1-4B as an example. Hereinafter, the cover tape peeling device of the carrier tape 300 according to this embodiment will be described.

First, the purpose of the cover tape peeling device of this embodiment will be described.

In the parts supply device 100 of the above-mentioned example, the blade edge 112b of the peeling part 112 of the cover tape peeling mechanism 110 is inserted from the front end surface 312 side of the tape conveying direction of the carrier tape 300 along the tape length direction of the carrier tape 300. In the case where the carrier tape 300 is moving in the tape conveyance direction A between the cover tape 306 and the base tape 304 , this entry may fail. The higher the moving speed (transfer speed) of the carrier tape 300 is, the higher the possibility that the cutting edge 112 b of the peeling portion 112 fails to enter between the cover tape 306 and the base tape 304 .

If the cutting edge 112b of the peeling portion 112 of the cover tape peeling mechanism 110 fails to enter between the cover tape 306 and the base tape 304, for example, the carrier tape 300 in the state where the cover tape 306 is not peeled off may be inserted into the component mounting device. The nozzle 202 of the transfer head 200 performs the possibility of transferring the component to the position where the component is sucked, that is, the component supply position Q. In addition, for example, the cutting edge 112b of the peeling part 112 may come into contact with the front end surface of the base tape 304 to stop the carrier tape 300 .

Therefore, the purpose of the cover tape peeling device 10 of this embodiment is to make the cutting edge 112b of the peeling unit 112 of the cover tape peeling mechanism 110 of the parts supply device 100 more reliably enter the cover tape 306 and the moving carrier tape 300 . between base strips 304 .

The cover tape peeling apparatus 10 of this embodiment is demonstrated using FIGS. 5-7, FIG. 8A, and FIG. 8B. FIG. 5 is a perspective view of the cover tape peeling device in a state where the carrier tape 300 is set. FIG. 6 is a diagram showing a cover tape peeling device viewed in the thickness direction (w-axis direction) which is the surface direction of the carrier tape 300 . 7 is a partial cross-sectional view (viewed in the u-axis direction) of the cover tape peeling device in the longitudinal direction of the carrier tape 300 .

In the cover tape peeling device 10 of the present embodiment shown in FIGS. 5 to 7 , the cutting edge 112 b of the peeling unit 112 of the cover tape peeling mechanism 110 of the component supply device 100 is extended to the tape length between the cover tape 306 and the base tape 304 . The relative entry in the direction (v-axis direction) becomes easy. In advance, that is, before the carrier tape 300 is put into the component supply device 100, as shown in FIGS. 8A and 8B, the cover tape 306 is transferred from the base tape 304 The front end surface 312 side of 300 is partially peeled off. Thus, a small gap G is formed between the cover tape 306 and the base tape 304 in the carrier tape 300 , allowing the blade edge 112 b of the peeling member 112 to easily enter along the tape length direction.

It should be noted that the “gap” here strictly refers to the portion where the cover tape 306 on the front end surface 312 side of the carrier tape 300 in the width direction is attached to the base tape 304 , that is, the gap between the cover tape 306 and the cover tape 306 . At least one of the two corners 306a, 306b is separated (partially peeled off) from the base tape 304 to form a space between the cover tape 306 and the base tape 304 (the area enclosed by the two-dot chain line shown in FIG. 8A ). ).

The cover tape peeling device 10 shown in FIGS. 5 to 7 is configured to form a gap G between the cover tape 306 and the base tape 304 as shown in FIGS. On the front end surface 312 side of the carrier tape 300 , the cover tape 306 is partially preliminarily peeled off the base tape 304 by a predetermined amount L along the tape length direction. It should be noted that the predetermined amount L is associated with the first accommodating portion 302 when no component is accommodated in the first accommodating portion 302 counted from the front end surface 312 side of the carrier tape 300 in the tape length direction. The degree of peeling amount (length). On the other hand, in the case where components are accommodated in the first storage portion 302 from the front end surface 312 side of the carrier tape 300, the predetermined amount L is such that the components accommodated in the first storage portion 302 do not move from the This accommodating part 302 falls out to the outside by such a peeling amount (length). It should be noted that, in the case where the first receiving portion 302 from the front end surface 312 side of the carrier tape 300 is cut (that is, the length in the tape length direction of the first receiving portion 302 is the same as that of the receiving portion 302 that is not cut). In the case of relatively short), a predetermined amount L may be set to exceed the first storage portion 302 to be cut in the tape length direction. In addition, when the components to be accommodated are small, and the accommodating portion 302 is made small as a result, the second to third accommodating portions 302 from the front end surface 312 side of the carrier tape 300 may be associated with each other. Set the specified amount L. In a broad sense, as long as the peeling amount of the cover tape 306 previously peeled by the cover tape peeling device 10 before feeding into the parts supply device 100 , that is, the predetermined amount L, does not affect the carrier tape along the tape path P of the parts supply device 100 The predetermined amount L may be large as long as the tape conveyance at 300 and the continuous peeling of the cover tape 306 by the cover tape peeling mechanism 110 are badly affected.

In the case of the present embodiment, the cover tape peeling device 10 is configured as shown in FIGS. 8A and 8B so that the side end surface 314a side of the carrier tape 300, that is, the cover tape 306 bonded with the adhesive 310a in the width direction The end portion of the carrier tape 300 is peeled off by a predetermined amount L from the front end surface 312 side of the carrier tape 300 along the tape length direction (v-axis direction).

They are disposed on the main body portion 12 in an opposing manner. Specifically, the front end 16a of the blade 16 is disposed on a main body that supports the main surface 300a (the surface on the cover tape 306 side) of the carrier tape 300, that is, the surface 306c (the surface not attached to the base tape 304) of the cover tape 306. The first reference surface 20a of the guide portion 20 of 12 is at a position in the tape thickness direction (position in the w-axis direction) separated by a predetermined distance D along the tape thickness direction (w-axis direction). The predetermined distance D is substantially the same as the thickness (for example, 0.04 to 0.07 mm) of the cover tape 306 .

It should be noted that, as shown in FIG. 9 , instead of supporting the surface 306c of the cover tape 306, the first reference surface 20a of the guide portion 20 may be the side to which the cover tape 306 is pasted and not covered by the cover tape 306. The portion of the surface 304 a of the covered base tape 304 (the portion where the transfer hole 308 is formed) is supported as the main surface 300 a of the carrier tape 300 . In this case, the position in the tape thickness direction (w-axis direction) of the front end 16a of the blade 16 is the same position as the surface 304a of the base tape 304, so the distance from the first reference plane 20a to the front end 16a of the blade 16 The predetermined distance D in the tape thickness direction (w-axis direction) is substantially zero.

With such a blade 16, the first reference surface 20a and the second reference surface 20b of the guide part 20 of the main body part 12 of the cover tape peeling device 10 abut on the main surface 300a (the surface on the cover tape 306 side) and the side end surface 314. When the carrier tape 300 in the state moves relative to the blade 16 along the tape length direction (v-axis direction), the front end 16a and the blade tip 16b of the blade 16 can enter from the front end surface 312 side of the carrier tape 300 along the tape length direction. between the cover tape 306 and the base tape 304.

In addition, the carrier tape 300 in the state where the front end 16a and blade edge 16b of the blade 16 have entered between the cover tape 306 and the base tape 304 faces the tape width direction (u-axis direction) on the side away from the second reference plane 20b. When the blade 16 moves relatively, the cover tape 306 is partially peeled off from the base tape 304 by the tip 16 b of the blade 16 . For example, one side of both ends in the tape width direction of the cover tape 306 bonded by the adhesive 310 a , that is, the portion on the side end surface 314 a side of the cover tape 306 is peeled from the base tape 304 .

In addition, the portion of the cover tape 306 on the side end surface 314a side of the carrier tape 300 is peeled off from the base tape 304, and the carrier tape 300 moves relative to the blade 16 in a direction away from the blade 16, so that the blade 16 moves from the cover tape 306 to the blade 16. When the base tapes 304 are separated, as a result, a gap G shown in FIGS. 8A and 8B is formed. That is, a gap G is formed between the corner portion 306a of the cover tape 306 on the side end surface 314a side of the carrier tape 300 and the base tape 304, that is, in the area surrounded by the two-dot chain line shown in FIG. 8A.

It should be noted that, before the front end 16a and the blade tip 16b of the blade 16 are about to enter between the cover tape 306 and the base tape 304, as shown in FIG. The first reference surface 20a of the guide part 20 and the pressing part 14 sandwich along the tape thickness direction (w-axis direction) (for example, the pressing part 14 and The end faces 14a and 20c in the tape length direction (v-axis direction) of each guide portion 20 are separated from the tip 16a of the blade 16 by a predetermined distance S (for example, 2 to 4 mm) along the tape length direction. The reason is that if the front end surface 312 side portion of the carrier tape 300 is clamped by the first reference surface 20a of the guide portion 20 and the pressing portion 14, the front end 16a and the knife edge 16b of the blade 16 are difficult to enter into the cover tape 306 and the base tape. Between 304. In addition, this is to secure the space 24 for accommodating the portion of the cover tape 306 peeled off by the blade 16 . It should be noted that, in FIG. 7 , the end faces 14 a and 20 c in the tape length direction of the pressing portion 14 and the guide portion 20 that sandwich the carrier tape 300 along the tape thickness direction are arranged in the same tape length direction. location, but is not limited to this. For example, as shown in FIG. 10, the distance S1 in the tape length direction between the end surface 20c of the guide part 20 and the front end 16a of the blade 16 may be different from the distance S1 between the end surface 14a of the pressing part 14 and the front end 16a of the blade 16. The distance S2 in the strip length direction. For example, setting the distance S1 to about 2 mm and setting the distance S2 to about 1 mm preferably ensures that the base tape 304 and the cover tape 306 can be flexed after the blade 16 enters between the base tape 304 and the cover tape 306. space.

The cover tape peeling device 10 further includes a stopper 26 that restricts the relative entry amount of the blade 16 in the tape length direction (v-axis direction) between the cover tape 306 and the base tape 304 to a predetermined amount L (for example, 2 to 10 mm). .

If the cover tape 306 is excessively peeled from the base tape 304 in the tape longitudinal direction (v-axis direction), the components accommodated in the storage portion 302 of the carrier tape 300 during conveyance by the above-mentioned component supply device 100 may drop to the ground. external. Alternatively, a tape jam may occur on the tape path P of the component supply apparatus 100 due to a portion of the cover tape 306 that has been peeled off excessively. In order to cope with this situation, a stopper 26 is provided in the cover tape peeling device 10 .

As shown in FIGS. 5 and 6 , the stopper 26 is provided on the main body 12 of the cover tape peeling device 10 , and is constituted by, for example, a part of the wall surface of the main body 12 . Specifically, the main surface 300a (the surface on the cover tape 306 side) and the side end surface 314a are arranged to abut against the first reference surface 20a and the second reference surface 20b of the guide portion 20 of the main body 12 in the tape length direction. The wall surface of the main body part 12 at the position facing the front end surface 312 of the carrier tape 300 in the state of the carrier tape 300, that is, at the position facing the front end surface of the base tape 304 which is a part of the front end surface 312 of the carrier tape 300. A part of it constitutes the stopper 26.

The blade 16 is provided in the main body portion 12 such that the protrusion amount of the blade 16 in the tape length direction (v-axis direction) with respect to the stopper portion 26 (part of the wall surface) becomes a predetermined amount L. By bringing the front end surface of the base tape 304 of the carrier tape 300 into contact with the stopper 26, the amount of entry of the blade 16 in the tape length direction (v-axis direction) between the cover tape 306 and the base tape 304 is restricted. For the specified amount L.

According to this embodiment, the cover tape 306 is peeled by a predetermined amount L along the tape length direction from the front end surface 312 side of the carrier tape 300 in the tape length direction by the cover tape peeling device 10 , and the cover tape 306 and the base tape 304 are separated by a predetermined amount L. A gap G is formed between them. By using the gap G previously formed by the cover tape peeling device 10, even if the moving speed of the carrier tape 300 moving along the tape length direction is high, the knife of the peeling part 110 of the cover tape peeling mechanism 110 of the parts supply device 100 can The tip 112b enters between the cover tape 306 and the base tape 304 .

In addition, the thickness of the cover tape 306 of the commercially available carrier tape 300 is substantially the same (for example, 0.04 to 0.07 mm). Therefore, by relatively moving the carrier tape 300 in a state where the surface (principal surface) 300a on the cover tape 306 side is in contact with the first reference surface 20a of the guide portion 20, the blade 16 is inserted into the base tape along the tape length direction. 304 and the cover tape 306, the cover tape 306 can be easily peeled by a predetermined amount L along the tape length direction from the front end surface 312 side from the carrier tape 300 having base tapes 304 of various thicknesses or shapes.

As mentioned above, although the said embodiment was given and demonstrated this invention, this invention is not limited to the said embodiment.

For example, in the cover tape peeling device 10 of the above-mentioned embodiment, as shown in FIG. The part of the cover tape 306 on the side end surface 314a side of 308 (the side attached to the base tape 304 by the adhesive 310a) is peeled off by a predetermined amount L along the tape length direction, but the present invention is not limited thereto.

The portion of the cover tape 306 that is preliminarily peeled off by the cover tape peeling device 10 in the tape conveying direction is different depending on the specification of the cover tape peeling mechanism 110 of the component supply device 100 . For example, the cover tape peeling mechanism 110 of the parts supply device 100 peels off the side end surface 314b close to the transfer hole in the tape width direction of the carrier tape 300 attached to the base tape 304 at both end sides of the cover tape 306 in the tape width direction. In the case of the part of the cover tape 306 on the carrier tape 300 side (attached to the side end side of the base tape 304 by the adhesive 310b), the cover tape peeling device 10 is configured so that the part of the cover tape 306 on the side end surface 314b side of the carrier tape 300 is The specified amount L is peeled off in the longitudinal direction of the tape. In addition, for example, when the cover tape peeling mechanism 110 of the parts supply device 100 is to peel the cover tape 306 over the entire range in the tape width direction, the cover tape peeling device 10 may be configured so that the cover tape 306 is removed over the entire range in the tape width direction. The tape 306 is peeled off by a predetermined amount L along the tape length direction.

In addition, for example, in the case of the above-mentioned embodiment, the blade 16 is fixed with respect to the main body part 12 . Therefore, by moving the carrier tape 300 relative to the blade 16 in the tape length direction and the tape width direction, the blade tip 16 a of the blade 16 peels the cover tape 306 from the base tape 304 by a predetermined amount in the tape length direction. However, the present invention is not limited thereto. The cover tape peeling device 10 may be configured by fixing the carrier tape 300 and moving the blade 16 relative to the carrier tape 300 in the tape length direction and the tape width direction. Alternatively, the blade 16 and the carrier tape 300 may be relatively moved by moving both the carrier tape 300 and the blade 16 along the tape length direction and the tape width direction of the carrier tape 300, thereby separating the cover tape 306 from the base tape 304. The cover tape peeling device 10 is configured such that a predetermined amount is previously peeled along the tape longitudinal direction.

In addition, for example, the cover tape peeling device 10 of the above embodiment may be configured such that the blade 16 peels the cover tape 306 from the base tape 304 by manually moving the carrier tape 300 in the tape length direction and the tape width direction. Therefore, the pressing portion 14 of the cover tape peeling device 10 can be omitted. That is, instead of the pressing part 14, the operator touches the back surface 300b (the surface to which the cover tape 306 is not attached) of the carrier tape 300 and presses the carrier tape 300 toward the first reference surface 20a of the guide part 20 of the main body part 12 to make the carrier tape 300 A surface (principal surface) 300 a of the tape 300 on the cover tape 306 side is in contact with the first reference surface 20 a of the guide portion 20 . Then, the operator maintains the pressure on the carrier tape 300 in order to maintain the contact, and at the same time moves the carrier tape 300 relative to the blade 16 along the tape length direction and the tape width direction, whereby the cover tape 306 is separated from the base tape. 304 is partially pre-stripped.

In connection with this, the present invention is not limited to the cover tape peeling device configured to partially peel the cover tape 306 from the base tape 304 manually. That is, a cover tape peeling device configured to automatically peel the cover tape 306 from the base tape 304 may also be used, and all of these are included in the present invention.

For example, the cover tape peeling device of the present invention that automatically partially peels the cover tape 306 from the base tape 304 has: a blade moving mechanism that moves the blade 16 along the tape length direction of the carrier tape 300; The carrier tape 300 moves along the tape width direction; and the control section controls the blade moving mechanism so that the blade 16 relatively enters between the cover tape 306 and the base tape 304 along the tape length direction, and after the entry, The tape moving mechanism controls to relatively move the carrier tape 300 in the tape width direction.

In a broad sense, in the present invention, for the carrier tape that is attached to the base tape at both end sides in the tape width direction of the cover tape, at least one side portion in the tape width direction of the cover tape is separated from the base tape in advance (on the carrier tape). (before feeding the tape into the component supply device) by a predetermined amount, thereby allowing the cover tape peeling mechanism of the component supply device to easily and continuously peel the cover tape from the base tape. Therefore, the present invention relates to a cover tape peeling device for a carrier tape that peels the cover tape from a carrier tape including a base tape on which a plurality of receiving members are arranged along the tape length direction and a cover tape. The cover tape is attached to the base tape at both ends in the width direction so as to cover the receiving portion. The cover tape peeling device of the carrier tape has a guide part provided with the cover tape side of the carrier tape. The reference surface that the surface of the cover tape abuts against; the blade, which is equipped with the relative movement of the carrier tape along the tape length direction under the state where the blade is in contact with the surface of the cover tape side and the reference surface of the guide part, enters into the cover tape and the reference surface of the guide part. a blade tip between the base tapes; and a stopper that contacts the end surface of the base tape in the tape length direction to limit the amount of entry of the blade between the cover tape and the base tape to a predetermined amount.
