Embodiments for Carrying Out the Invention

[0010] Next, embodiments of the present disclosure will be described with reference to the drawings. FIG. 1 is a configuration diagram showing an outline of the configuration of the component mounter 10. FIG. 2 is a configuration diagram showing an outline of the configuration of the tape feeder 12. In FIG. 1, the left-right direction is the X direction, the front-back direction is the Y direction, and the up-down direction is the Z direction.

[0011] As shown in FIG. 1, the component mounter 10 includes a substrate transfer device 11 that transfers the substrate S, a tape feeder 12 that supplies components, a head 14 in which nozzles for adsorbing components are arranged to be movable up and down, and a transfer device 15 that moves the head 14 in the XY directions. The substrate transfer device 11 has two pairs of conveyor belts provided at intervals in the front-back direction of FIG. 2 and extending in the left-right direction, and the substrate S is transferred from left to right in the figure by each conveyor belt.

[0012] The tape feeder 12 supplies components, for example, by sending out a tape T in which components are accommodated at a predetermined pitch to a supply position where the nozzles can pick up the components, and a plurality of sets of the tape feeder 12 are provided in the component mounter 10 so as to be able to supply a plurality of types of components. As shown in an example in FIG. 2, the tape T is composed of a bottom tape BT in which cavities (recesses) for accommodating components are formed at predetermined intervals, and a film-like cover tape CT that covers the bottom tape BT. The tape feeder 12 includes a reel 13 around which the tape T is wound, pulls out the tape T from the reel 13 and sends it to the supply position, and peels off the cover tape CT from the bottom tape BT in front of the supply position, so that the components are in an exposed state, that is, a pick-up possible state. Among the used tapes T after supplying the components, the bottom tape BT is sent downward on the rear side of the tape feeder 12, and the cover tape CT is sent downward on the front side of the tape feeder 12.

[0013] In addition, the component mounting machine 10 includes a bottom tape cutting device 20 that cuts the bottom tape BT of the used tape T after supplying the components, and a cover tape cutting device 30 that cuts the cover tape CT. The cover tape cutting device 30 is provided on the front side of the component mounting machine 10, and the bottom tape cutting device 20 is provided on the rear side of the cover tape cutting device 30. Both the bottom tape cutting device 20 and the cover tape cutting device 30 have a similar configuration including a cutting mechanism for cutting the used tape T (bottom tape BT or cover tape CT) and a duct for guiding the used tape T to the cutting mechanism. The following is an explanation of the configuration of the cover tape cutting device 30.

[0014] FIG. 3 is a perspective view of the cover tape cutting device 30. FIG. 4 is a perspective view of the cutting mechanism 40 of the cover tape cutting device 30. FIG. 5 is a cross-sectional view of the cover tape cutting device 30. The cover tape cutting device 30 is a substantially rectangular parallelepiped unit having a cover 31 (see FIG. 1) that covers a part of the upper side and the front, a base plate 32 at the bottom, and side walls 33 on the left and right. FIG. 3 shows a perspective view with the cover 31 removed and the right side wall 33 omitted.

[0015] The cover tape cutting device 30 includes a duct 35 that guides the used cover tape CT downward, a cutting mechanism 40 that cuts the cover tape CT that has passed through the duct 35, a brush 50 attached to the lower end of the duct 35, and a control unit 53 that controls the operation of the cutting mechanism 40. The control unit 53 is attached to a partition wall 34 that divides the inside of the cover tape cutting device 30.

[0016] The duct 35 includes a pair of duct walls 37 that, together with the side wall 33, form an internal passage 36 through which the cover tape CT passes. The pair of duct walls 37 are formed with tapered surfaces 37a that incline so as to approach each other downward from the upper end, narrowing the internal passage 36, up to near the center in the vertical (height) direction, and extend parallel to each other from near the center to the lower end. For this reason, the internal passage 36 has an upper tapered portion 36a and a lower straight portion 36b. Also, both the upper and lower openings of the duct 35 are formed in a rectangular shape (elongated rectangular shape) with the long side in the left-right direction and the short side in the front-rear direction.

[0017] The cutting mechanism 40 includes a movable blade 41 movable in the front-rear direction, a fixed blade 42 disposed immovably so as to face the movable blade 41, and a drive unit 43 that drives the movable blade 41 to move. The movable blade 41 and the fixed blade 42 are formed in a substantially elongated rectangular shape in top view, and the long side is formed to be substantially the same length as the long side of the duct 35 (the lower opening). Also, the movable blade 41 is formed such that the side facing the fixed blade 42 is recessed in a substantially V shape in top view from both ends toward the center. The cutting mechanism 40 cuts the cover tape CT by moving the movable blade 41 in the front-rear direction from the standby position (see FIGS. 3 and 5) to the cutting position overlapping the fixed blade 42 by driving of the drive unit 43.

[0018] The drive unit 43 includes a motor 44, a slide plate 46 slidable integrally with the movable blade 41, a home position detection sensor 48 that detects the slide plate 46, and a plunger 49 that positions the slide plate 46.

[0019] The motor 44 is arranged such that its rotation axis faces downward, and the drive gear attached to the rotation axis transmits the rotational driving force to the driven gear 45b via the transmission gear 45a. The transmission gear 45a and the driven gear 45b are arranged below the slide plate 46, and a pin (not shown) eccentric from the rotation center is provided on the upper surface of the driven gear 45b so as to protrude upward. The slide plate 46 is formed with a long hole 46a into which the pin of the driven gear 45b is movably inserted (engaged). The long hole 46a is formed such that its longitudinal direction is the left - right direction. Therefore, when the driven gear 45b rotates due to the drive of the motor 44, the rotational movement of the pin of the driven gear 45b accompanying the rotation is converted into a reciprocating linear motion within the long hole 46a, causing the slide plate 46 to reciprocate in the front - rear direction. That is, the drive unit 43 is configured to convert the rotational motion of the motor 44 into the linear motion of the slide plate 46.

[0020] Also, a detection piece 47 is attached to the upper surface of the slide plate 46. The origin detection sensor 48 detects that the movable blade 41 is at the origin position (stand - by position) by detecting the detection piece 47 when the slide plate 46 is at the origin position. The plunger 49 is arranged to abut against an end wall portion 46b erected from the front - side edge of the slide plate 46. The plunger 49 positions the slide plate 46 at the origin position by abutting against the end wall portion 46b of the slide plate 46 that has slid forward.

[0021] The brushes 50 are attached to the outer surfaces of each of the pair of duct walls 37 so as to extend downward from the lower ends 37b (see FIG. 6) of each of the duct walls 37. The brushes 50 are formed of flexible brush fibers such as nylon, acrylic, polyethylene, natural fibers, etc., and may be formed of a plurality of types of brush fibers. Also, the brushes 50 can use antistatic fibers in order to suppress the sticking of the cover tape CT due to static electricity.

[0022] FIG. 6 is a perspective view showing the state before the brush 50 is attached. As shown in the figure, since the movable blade 41 and the fixed blade 42 are provided at positions separated downward from the lower ends 37b of the respective duct walls 37, a gap G is formed between each lower end 37b and the movable blade 41 or the fixed blade 42. The brush 50 is attached over the entire length of each of the long sides on the movable blade 41 side and the long sides on the fixed blade 42 side of the opening at the lower end 37b of the duct 35 so as to close the gap G (see FIGS. 3 and 5). The brush 50 on the fixed blade 42 side is provided so as to extend to a position where it abuts against the edge of the upper surface of the fixed blade 42. On the other hand, the brush 50 on the movable blade 41 side is provided so as to extend to a position below the movable blade 41 so as to cover the front side (the rear side in the Y direction) in the moving direction of the movable blade 41 in the standby position. Since the movable blade 41 moves so as to overlap the fixed blade 42, the movable blade 41 is disposed at a position higher than the fixed blade 42. For this reason, the brush 50 on the fixed blade 42 side and the brush 50 on the movable blade 41 side are such that the latter is slightly longer or of substantially the same length. Each brush 50 may have different mounting positions (heights) with the lengths of the brush fibers being the same.

[0023] In the cover tape cutting device 30 configured as described above, the state in which the cover tape CT is guided is shown in FIG. 7. As described above, since the tape T is pulled out from the state of being wound around the reel 13, the bottom tape BT and the cover tape CT often have winding marks after supplying the parts, and the lower end (tip) of the cover tape CT easily protrudes from the above-described gap G. Since the cover tape cutting device 30 of the present embodiment includes the brush 50 that closes the gap G, it is possible to prevent the cover tape CT from protruding forward (dashed line in FIG. 7) or protruding backward (one-dot chain line in FIG. 7). For this reason, the cover tape CT can be appropriately guided up to the cutting position of the cutting mechanism 40, that is, the position between the movable blade 41 and the fixed blade 42. Further, the cover tape cutting device 30 cuts the cover tape CT by reciprocating the movable blade 41 in the front-rear direction (arrow direction in FIG. 7). Since the brush 50 has flexibility, it can cover the front side (the rear side in the Y direction) in the moving direction of the movable blade 41, and can suppress an increase in the load on the operation of the movable blade 41 and cut smoothly. Furthermore, since the brush fibers of the brush 50 have antistatic properties, it is possible to suppress the adhesion of the cover tape CT due to static electricity and appropriately guide it downward.

[0024] Here, the correspondence between the components of the present embodiment and the components of the present disclosure will be clarified. The tape feeder 12 of the present embodiment corresponds to the feeder, the duct 35 corresponds to the duct, the movable blade 41 and the fixed blade 42 correspond to the cutting blades, the cutting mechanism 40 corresponds to the cutting mechanism, and the brush 50 corresponds to the brush. The movable blade 41 corresponds to the movable blade, and the fixed blade 42 corresponds to the fixed blade. In addition, in the present embodiment, an example of the cutting method of the present disclosure is also clarified.

[0025] In the cover tape cutting device 30 of the present embodiment described above, a brush 50 having flexibility and extending downward from the lower end 37b of the duct 35 so as to close the gap G with the movable blade 41 and the fixed blade 42 is provided. For this reason, it is possible to perform smooth cutting while appropriately guiding the used cover tape CT.

[0026] In addition, since the brush 50 is provided so as to close the gap G over the entire length of each of the pair of long sides at the opening of the lower end 37b, it is possible to more appropriately guide the used cover tape CT so that it does not pop out to the outside.

[0027] In addition, since the brush 50 on the fixed blade 42 side extends to a position where it abuts against the edge of the upper surface of the fixed blade 42 (the edge on the movable blade 41 side), it is possible to prevent the cover tape CT from getting caught on the upper surface of the fixed blade 42 and causing jamming. Since the brush 50 on the movable blade 41 side extends to a position below the movable blade 41 in the standby position, it is possible to prevent the cover tape CT from getting caught on the upper surface of the movable blade 41 or entering the gap between the movable blade 41 and the upper and lower members, etc., and causing jamming. Further, since the cover tape CT is in the form of a relatively thin film and is likely to come out from the gap G, the effect of preventing it from popping out is high.

[0028] It should be noted that the present disclosure is not limited to the above-described embodiments at all, and it goes without saying that various embodiments can be implemented as long as they belong to the technical scope of the present disclosure.

[0029] For example, in the above-described embodiment, the brush 50 is attached over the entire length of each of the pair of long sides at the opening of the lower end 37b of the duct 35, but it is not limited to this. For example, when the duct 35 forms an opening by a duct wall (side wall) different from the side wall 33, the brush may be attached over the entire length of not only the pair of long sides but also the pair of short sides. Further, it is not limited to the case where the brush is attached over the entire length of the long side or the short side, and the brush may be attached so as to close at least a part of the lateral direction of the gap G, such as being partially attached. For example, based on the type and material of the tape T (cover tape CT), the tendency of the winding habit, etc., the direction in which it is likely to pop out is specified, and the brush may be attached over the entire length to the gap G in that direction, and the brush may be partially attached to the gap G in other directions.

[0030] In the above-described embodiment, the brush 50 on the fixed blade 42 side extends to a position where it abuts against the edge of the upper surface of the fixed blade 42. However, the present invention is not limited to this, and it may be attached so as to block at least a part of the height direction of the gap G, such as extending to the vicinity of the upper surface position of the fixed blade 42. Similarly, the brush 50 on the movable blade 41 side extends to a position below the movable blade 41 in the standby position. However, the present invention is not limited to this, and it may be attached so as to block at least a part of the height direction of the gap G, such as extending to the vicinity of the upper surface position of the movable blade 41. Note that the brush 50 is attached to the outer surface of the duct wall 37. However, the present invention is not limited to this, and it may be attached to the end surface of the lower end 37b of the duct wall 37, or may be attached to the inner surface of the duct wall 37 after ensuring that the cover tape CT does not get caught. Further, the brush 50 only needs to have at least flexibility and does not necessarily have antistatic properties, but preferably has antistatic properties. Also, the brush 50 may be more flexible on the movable blade 41 side than on the fixed blade 42 side.

[0031] Further, an air blowing portion 55 that blows air downward from above may be provided in the duct 35. FIG. 8 is a cross-sectional view of a modified example of the cover tape cutting device 130. In the modified example, the same components as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted. In the duct 135 of the modified example, a tapered surface 37a is formed on the rear duct wall 37 (one side) in the same manner as in the embodiment, but no tapered surface is formed on the front duct wall 137 (the other side).

[0032] The air blowing portion 55 is provided on the upper side of the duct wall 137. The air blowing portion 55 includes a blowing pipe 56 attached so as to extend along the left - right direction of the duct wall 137, and a cover plate 57 attached to the duct wall 137 so as to cover the blowing pipe 56 from above. The blowing pipe 56 is a cylindrical pipe with an air supply pipe (not shown) connected to one end and the other end closed, and a plurality of blowing holes are formed at equal intervals in the left - right direction on the lower side. This blowing pipe 56 is attached such that the air blowing direction is in the direction of the arrow in FIG. 8, that is, at the lower end of the tapered surface 37a (the boundary between the tapered portion 36a and the straight portion 36b). Also, the cover plate 57 is a flat - plate - shaped member formed so as to cover the entire length of the blowing pipe 56, and by being attached such that the upper surface forms a tapered surface, it prevents the cover tape CT from getting caught on the upper part of the blowing pipe 56. Note that the cover plate 57 may be integrated with the duct wall 137.

[0033] In this modification, since the air blowing portion 55 blows air downward in the duct 135, the used cover tape CT can be appropriately guided by the air flow. Also, since the air blowing portion 55 blows air toward the lower end of the tapered surface 37a, it can prevent the cover tape CT from clogging at the location where the internal passage 136 becomes narrow, and can more appropriately guide the cover tape CT. That is, as described above, if the cover tape CT has a curl, it is not smoothly guided at the location where the internal passage 136 becomes narrow and is likely to clog. However, in the modification, the cover tape CT can be guided downward by straightening the curl and pushing it in by the air flow.

[0034] Note that the air blowing portion 55 is not limited to being provided in the cover tape cutting device 130 of the modified example, and may be provided in the cover tape cutting device 30 of the embodiment. Further, although the air blowing portion 55 includes the cover plate 57, it is not limited thereto. For example, depending on the mounting position of the air blowing portion 55 and the shape of the blowing pipe 56, etc., if there is no risk of the cover tape CT being caught, the cover plate 57 may not be provided. Also, it is not limited to having only one blowing pipe 56, and a plurality of blowing pipes may be provided. Further, it is not limited to blowing air toward the lower end of the tapered surface 37a, and any device may be used as long as it blows air from the upstream side to the downstream side in a predetermined direction for guiding the cover tape CT.

[0035] In the above-described embodiment, the duct 35 guides the cover tape CT from above to below along the vertical direction (Z direction), but it is not limited thereto, and any device may be used as long as it guides the cover tape CT in a predetermined direction such as obliquely downward. Also, the opening at the lower end of the duct 35 is not limited to a rectangular shape, and may be other shapes such as an oval shape or a circular shape. Further, the cutting mechanism 40 may be arranged with a gap on the downstream side in a predetermined direction with respect to the duct 35. The cutting mechanism 40 is not limited to including a pair of movable blades 41 and a fixed blade 42, and may be composed of a plurality of movable blades.

[0036] In the above-described embodiment, the content of the present disclosure has been described by applying it to the cover tape cutting device 30, but it is not limited thereto, and it may be applied to a cutting device for cutting a used tape such as the bottom tape cutting device 20.

[0037] Here, the component mounter of the present disclosure may be as follows. For example, in the component mounter of the present disclosure, the duct is formed in a rectangular shape having a long side and a short side at the opening of the end portion, and the cutting mechanism cuts the used tape by moving a cutting blade having a length corresponding to the long side in the direction of the short side, and the brush may be provided so as to close the gap over the entire length of each of the pair of long sides of the opening. In this way, the used tape can be more appropriately guided to the cutting blade so as not to fly out to the outside.

[0038] In the component mounting machine of the present disclosure, the cutting mechanism has, as the cutting blade, a fixed blade fixedly immovable and a movable blade movable in the direction of the short side from a predetermined standby position to a cutting position overlapping the fixed blade. The brush may be provided so as to extend to a position where it abuts against the edge of the fixed blade on the fixed blade side among the pair of long sides and to a position downstream of the movable blade in the standby position on the movable blade side. In this way, it is possible to appropriately prevent the used tape from popping out to the outside on each of the fixed blade side and the movable blade side.

[0039] In the component mounting machine of the present disclosure, it may be provided with an air blowing portion provided in the duct and blowing air from the upstream side to the downstream side in the predetermined direction. In this way, the used tape can be more appropriately guided by the air flow.

[0040] In the component mounting machine of the present disclosure, the duct may have a tapered surface inclined so that the internal passage becomes narrower from the upstream side to the downstream side in the predetermined direction, and the air blowing portion may be provided so as to blow air toward the downstream end of the tapered surface in the predetermined direction. In this way, it is possible to prevent the used tape from being clogged at the location where the internal passage becomes narrower and to more appropriately guide the used tape.

[0041] In the component mounting machine of the present disclosure, the tape may be composed of a bottom tape that houses a plurality of components and a cover tape that covers the bottom tape, the feeder supplies the components by peeling the cover tape from the bottom tape, and the duct guides the peeled cover tape as the used tape. Since the cover tape is relatively thin and easily comes out through the gap, the significance of applying the present disclosure is high.

[0042] The tape cutting method of the present disclosure is A feeder that sends a tape containing a plurality of components to a supply position, a duct that guides the used tape after supplying the components at the supply position in a predetermined direction, and a cutting mechanism in which a cutting blade is disposed with a gap on the downstream side in the predetermined direction with respect to the duct. A tape cutting method in a component mounter that mounts the components supplied to the supply position, The used tape guided to the cutting blade is cut by the cutting blade with a brush that extends in the predetermined direction and has flexibility so as to block at least a part of the gap from the downstream end of the duct in the predetermined direction. This is the gist.

[0043] In the tape cutting method of the present disclosure, since the used tape guided to the cutting blade is cut by the cutting blade with a brush that extends in the predetermined direction and has flexibility so as to block at least a part of the gap from the downstream end of the duct in the predetermined direction, smooth cutting can be achieved while appropriately guiding the used tape to the cutting blade. In this tape cutting method, various aspects of the above-described component mounter may be adopted, or steps for realizing each function may be added.
