Description

Component mounter

[0001] The technology disclosed in this specification relates to a component mounter. In particular, it relates to a component mounter provided with a cutting device for cutting a tape discharged from a feeder.

[0002] In the component mounter of Patent Document 1, the leading end of the empty tape after component supply is discharged from the lower surface of the feeder and cut by a cutting blade that moves horizontally along the lower surface of the feeder. When the leading end is cut, in the component mounter, a part of the empty tape hangs down from the lower surface of the feeder. Therefore, when removing the feeder from the component mounter, the motor that feeds the tape of the feeder is rotated in the reverse direction to wind up the empty tape into the feeder. This suppresses a part of the empty tape that has hung down from the lower surface of the feeder from getting caught in the component mounter when removing the feeder from the component mounter.

[0003] Japanese Patent Application Laid-Open No. 2013-254895

[0004] This specification provides a technology that can easily attach and detach the feeder to and from the component mounter while suppressing entanglement of the empty tape after cutting as compared with the prior art.

[0005] The component mounting machine disclosed herein includes a feeder having a reel on which a tape containing components is wound, the feeder having a supply surface for supplying the components contained on the tape fed out from the reel to a mounting unit provided by the component mounting machine, and a feeder opening for discharging the tape after the components have been supplied on the supply surface to the outside of the feeder; a holding device for detachably holding the feeder, the holding device being configured to allow the feeder to be attached and detached along the attachment / detachment direction; and a cutting device positioned opposite the feeder opening of the feeder, for cutting the tape discharged from the feeder opening. The cutting device has a body having an entrance opening positioned opposite the feeder opening when the feeder is mounted on the holding device, and a guide passage communicating with the entrance opening; and a cutting section for cutting the tape guided through the feeder opening and the entrance opening to the guide passage. The cutting device is configured such that when the tape discharged from the feeder opening is cut at the cutting section, the cut end of the tape protrudes to the outside from the feeder opening. The feeder, the holding device, and the cutting device are configured such that when the feeder is attached to or detached from the holding device, the cut end of the tape protruding from the feeder opening is located within the range of the entrance opening of the guide passage in a direction perpendicular to the attachment / detachment direction.

[0006] In the above-described component mounting machine, when the feeder is loaded or unloaded from the holding device along the loading / unloading direction, the cut end of the tape protruding from the feeder opening is located within the range of the guide passage's entrance opening in a direction perpendicular to the loading / unloading direction. Therefore, when loading or unloading the feeder from the holding device, the cut end of the tape does not come into contact with the periphery of the entrance opening. As a result, entanglement of the tape after cutting can be suppressed. In the above-described component mounting machine, it is not necessary to wind the tape protruding from the feeder opening into the feeder simply by positioning the cut end of the tape within the range of the entrance opening. Therefore, compared to conventional technology, the feeder can be easily loaded or unloaded from the holding device of the component mounting machine while suppressing tape entanglement.

[0007] Side view of the component mounting machine of the first embodiment. Perspective view of the area around the feeder opening of the feeder provided in the component mounting machine of the first embodiment. Enlarged view of the area within line III in Figure 1. Enlarged view similar to Figure 3 in the component mounting machine of the second embodiment.

[0008] The main features of the embodiments described below are listed below. Note that the technical elements described below are independent technical elements that exhibit technical usefulness individually or in various combinations, and are not limited to the combinations described in the claims at the time of filing.

[0009] (Feature 1) In the component mounting machine described above, the main body may include a base. In this case, the base may include a cutting surface having an inlet opening, a cutting back surface located on the opposite side of the cutting surface from the feeder opening, extending along the cutting surface and having an outlet opening, and a through hole extending from the inlet opening of the cutting surface to the outlet opening of the cutting back surface and penetrating the base. Furthermore, the through hole defines the guide passage, the supply surface extends horizontally on the upper surface of the feeder, the feeder opening is located below the supply surface, and the cutting surface and cutting back surface of the base may be inclined with respect to the loading / unloading direction such that they move vertically away from the supply surface of the feeder as the loading / unloading direction progresses in the loading / unloading direction of the feeder. The leading edge of the tape discharged from the feeder opening passes through the through hole in the base portion and protrudes from the outlet opening before being cut by the cutting device, and the cut end of the tape may pass over the peripheral edge of the inlet opening, which is located in a region farther vertically from the supply surface, as the feeder is removed from the holding device along the removal direction after the leading edge of the tape has been cut by the cutting device, while avoiding the supply surface.

[0010] With this configuration, the inclination of the cut surface and back surface of the base portion causes the periphery of the inlet opening to move vertically away from the supply surface as the feeder moves in the removal direction. For example, when removing the feeder from the holding device along the removal direction, the cut end of the tape is more likely to pass while avoiding the surface periphery towards the supply surface, compared to a configuration in which the cut surface extends parallel to the mounting / removal direction. As a result, tape entanglement can be suppressed without winding up the tape after cutting, and the feeder can be easily removed from the holding device. Similarly, when attaching the feeder to the holding device, the cut end of the tape passes while avoiding the surface periphery towards the supply side. As a result, the feeder can be easily attached to the holding device while suppressing tape entanglement.

[0011] (Feature 2) In the component mounting machine described above, the lower surface of the feeder in which the feeder opening is formed may extend parallel to the cutting surface of the cutting device.

[0012] With this configuration, by positioning the lower surfaces of the feeders, which extend parallel to each other, and the cutting surface of the cutting device facing each other, the cutting device can be brought closer to the feeders. As a result, the vertical size of the component mounting machine can be reduced.

[0013] (Feature 3) In the component mounting machine described above, the cutting section may include a fixed blade that forms the back edge of the periphery of the outlet opening, which is located in a region close to the supply surface in the vertical direction, and a movable blade that can move toward the fixed blade from a position opposite to the fixed blade.

[0014] With this configuration, the tip of the tape can be cut by a fixed blade located in a region close to the supply surface in the vertical direction. As a result, the position of the cut end of the tape is further from the surface edge in the vertical direction. Therefore, when loading and unloading the feeder, the cut end of the tape can pass more reliably away from the surface edge towards the supply side.

[0015] (Feature 4) In the component mounting machine described above, the movable blade may be movable along the cutting surface toward the fixed blade.

[0016] With this configuration, the movable blade can be moved stably along the back surface of the cut, ensuring that the tip of the tape is cut reliably.

[0017] (Feature 5) In the component mounting machine described above, the feeder opening may have a guide shape that causes the tape to protrude in a direction perpendicular to the cutting surface.

[0018] With this configuration, the guide shape of the feeder opening causes the tape to protrude in a direction perpendicular to the cutting surface. As a result, the tape is more likely to align perpendicularly with the fixed blade provided on the back of the cutting surface. This ensures that the tip of the tape is reliably cut.

[0019] (Feature 6) In the component mounting machine described above, the loading / unloading direction may be parallel to the horizontal direction. In that case, after the tape discharged from the feeder opening is cut by the cutting device, the tape may hang down from the feeder opening, and the vertical distance between the feeder opening and the surface edge may be longer than the distance between the feeder opening and the back edge.

[0020] With this configuration, even if the tape hangs downward from the feeder opening, the cut end of the tape can pass above the surface edge when the feeder is installed or removed.

[0021] (Feature 7) In the component mounting machine described above, the mounting / unmounting direction may be parallel to the horizontal direction. After the tape discharged from the feeder opening is cut by the cutting device, the tape may maintain a position extending from the feeder opening toward the rear edge, and the vertical distance between the feeder opening and the front edge may be longer than the vertical distance between the feeder opening and the rear edge.

[0022] When the tape maintains an orientation extending from the feeder opening toward the rear edge, the cut end of the tape is positioned higher compared to when the tape hangs downward from the feeder opening. Therefore, with this configuration, the surface edge of the cutting device can be positioned higher compared to when the tape hangs downward from the feeder opening. This allows for a reduction in the vertical size of the component mounting machine.

[0023] (Feature 8) In the component mounting machine described above, the guide shape may be formed by an attachment that is detachably connected to the feeder.

[0024] With this configuration, for example, by attaching an attachment to an existing feeder, the tape can be easily made to protrude in a direction perpendicular to the cutting surface.

[0025] (Feature 9) In the component mounting machine described above, the cutting surface and the cutting back surface may be inclined at an angle of 45° or more with respect to the mounting / unmounting direction.

[0026] With this configuration, the inclination of the cutting surface and the cutting back surface with respect to the loading / unloading direction becomes large, at 45° or more. Therefore, compared to a configuration with an inclination of less than 45°, the distance of the periphery of the inlet opening of the cutting device in a direction perpendicular to the loading / unloading direction can be increased, for example. As a result, when loading or unloading the feeder, the cut end of the tape can easily pass above the periphery of the surface. In another embodiment, the cutting surface and the cutting back surface may be inclined at an angle smaller than 45° with respect to the loading / unloading direction.

[0027] (First Embodiment) The component mounting machine 10 of the first embodiment will be described with reference to the drawings. The component mounting machine 10 is a device that mounts components 4 onto the surface of a substrate 2. The component mounting machine 10 is also called an electronic component mounting device or a chip mounter. The substrate 2 is a circuit board, and the components 4 are electronic components. Typically, the component mounting machine 10 is installed together with other substrate work machines such as a solder printing machine and a substrate inspection machine to form a series of mounting lines. In the following, the +Z direction in the coordinate system of the figure may be described as "up" in the vertical direction, and the opposite direction may be described as "down" in the vertical direction. Furthermore, the -X direction in the coordinate system of the figure may be described as "front" in the horizontal direction, and the opposite direction may be described as "back" in the horizontal direction. Furthermore, the right direction (i.e., the -Y direction) as seen from the perspective of a worker standing in front of the component mounting machine 10 facing the machine may be simply described as "right," and the opposite direction may be described as "left."

[0028] As shown in Figure 1, the component mounting machine 10 includes a feeder 20, a holding device 12, a substrate conveyor 14, a mounting unit 15 consisting of a mounting head 16 and a head moving device 18, a tape waste box 19, and a cutting device 50.

[0029] The feeder device 20 has a plurality of feeders arranged in the left-right direction (i.e., the direction towards the back of the page in Figure 1). Hereinafter, each individual feeder of the feeder device 20 may be referred to as feeder 20. Each feeder 20 contains a plurality of parts 4. The feeder 20 is detachably attached to the holding device 12 and supplies the parts 4 to the mounting unit 15. The feeder 20 comprises a feeder body 21, a reel 30, a plurality of sprockets 22, a guide 23, and an attachment 40.

[0030] The reel 30 has a long tape 32 wound around it. The tape 32 has a carrier tape 36 and a cover tape 34 that is attached to the upper surface of the carrier tape 36. The tape 36 accommodates a plurality of parts 4 between the two tapes 34 and 36. In this embodiment, the carrier tape 36 is a so-called paper tape made of paper material. The carrier tape 36 has a strip shape, and the parts 4 are placed on its upper surface. The tape 32 is pushed backward from the reel 30 by a plurality of sprockets 22 and supplied to the guide 23. The guide 23 has a slit (not shown) that peels the rear end of the cover tape 34 of the tape 32 away from the carrier tape 36. As a result, the parts 4 placed on the carrier tape 36 are exposed and supplied to the supply surface 24 located on the upper surface of the feeder 20.

[0031] The cover tape 34, which has peeled off from the carrier tape 36, is fed forward via the guide 23. Meanwhile, the carrier tape 36, after the component 4 has been supplied on the supply surface 24, is fed downward along the rear surface of the feeder 20 and discharged to the outside of the feeder 20 via the attachment 40.

[0032] Here, we will refer to Figure 2 to explain the detailed structure of the attachment 40 of the feeder 20. Figure 2 shows a perspective view of the feeder 20 from below. The attachment 40 is a member that restricts the discharge direction of the carrier tape 36. In Figure 2, the carrier tape 36 is shown with a dashed line for easier understanding. The attachment 40 has a rectangular parallelepiped shape. The attachment 40 clamps both the left and right sides of the feeder body 21 and is detachably fixed to the lower surface 26 of the feeder body 21 by a plurality of screws 45. The attachment 40 has a feeder opening 42 for discharging the carrier tape 36. The feeder opening 42 communicates with a tape path 28 (see Figure 3) that guides the carrier tape 36 downward within the feeder body 21. A guide-shaped portion 44 is formed at the top of the feeder opening 42. The guide-shaped portion 44 is a groove that accommodates the carrier tape 36 and extends toward the lower surface 26. The carrier tape 36 is discharged to the outside of the feeder 20 along the guide-shaped portion 44. In this way, by guiding the carrier tape 36 with an attachment 40 that is detachably configured to be attached to the feeder body 21, the discharge direction of the carrier tape 36 can be easily changed, even in existing feeders that are configured to discharge the carrier tape simply in a straight line downwards by gravity.

[0033] As shown in Figure 1, a cutting device 50 is located below the attachment 40. Details will be explained later with reference to Figure 3, but the cutting device 50 is a device that cuts the carrier tape 36 discharged from the feeder 20. Below the cutting device 50 is a tape waste box 19. The leading edge of the carrier tape 36 cut by the cutting device 50 falls downward and is collected in the tape waste box 19.

[0034] The holding device 12 holds the feeder 20 mounted on the component mounting machine 10 from below. The holding device 12 comprises a plurality of rails 13. The plurality of rails 13 extend along the front-rear direction (i.e., the horizontal direction) and restrict the position of the feeder 20 by engaging with the lower end of the feeder 20. For example, when all the components 4 contained in the feeder 20 have been mounted on the circuit board 2, the feeder 20 is removed from the holding device 12 along the plurality of rails 13. That is, the feeder 20 is removed from the holding device 12 by moving along the horizontal direction. The feeder 20 removed from the holding device 12 is carried by an operator to the kitting space (not shown) and a new reel 30 is mounted on it. The feeder 20 with the new reel 30 is then reattached by an operator to the holding device 12 of the component mounting machine 10 along the plurality of rails 13. Thus, in the component mounting machine 10 of this embodiment, the feeder 20 moves along a plurality of rails 13 extending in the horizontal direction and components are mounted and unmounted along the mounting / unmounting direction D10.

[0035] The mounting head 16 of the mounting unit 15 has a cylindrical nozzle 6. The nozzle 6 extends downward from the mounting head 16. The nozzle 6 is detachably attached to the mounting head 16. The component mounting machine 10 attracts the component 4 supplied to the supply surface 24 to the tip of the nozzle 6 by maintaining negative pressure inside the nozzle 6 with a compressor (not shown). The mounting head 16 is movable along the Z-axis, bringing the nozzle 6 closer to and further away from the supply surface 24 of the feeder 20 or the surface of the substrate 2. When the mounting head 16 brings the tip of the nozzle 6 close to the surface of the substrate 2 and the negative pressure inside the nozzle 6 is released, the component 4 is mounted on the surface of the substrate 2. Note that the mounting head 16 is not limited to having a single nozzle 6, but may have multiple nozzles 6.

[0036] The head moving device 18 moves the mounting head 16 between the supply surface 24 of the feeder 20 and the substrate 2. In this embodiment, the head moving device 18 is an XY robot that moves the moving base 18a along the XY plane, and the mounting head 16 is fixed to the moving base 18a. Note that the mounting head 16 is not limited to being fixed to the moving base 18a, but may be detachably attached to the moving base 18a.

[0037] The substrate conveyor 14 is a device for loading, positioning, and unloading substrates 2. In this embodiment, the substrate conveyor 14 includes a pair of belt conveyors and a support device (not shown) that supports the substrates 2 from below.

[0038] Referring to Figure 3, the detailed structure of the cutting device 50 will be described. The cutting device 50 comprises a device body 51 and a cutting section 60. The device body 51 has a flat plate shape extending in the left-right direction. The device body 51 comprises legs extending in the vertical direction and a base section 52 that extends from the upper end of the legs, inclined upward towards the rear.

[0039] The base portion 52 of the device body 51 includes a cutting surface 53 facing the attachment 40 and a cutting surface 56 located on the opposite side of the cutting surface 53 from the attachment 40. Since the base portion 52 has a constant plate thickness, the cutting surface 53 and the cutting surface 56 extend parallel to each other. That is, the cutting surface 56 extends along the cutting surface 53. The cutting surface 53 has an inlet opening 54, and the cutting surface 56 has an outlet opening 57. The openings 54 and 57 are connected to each other by a through hole 55. The through hole 55 extends in a direction perpendicular to the cutting surface 53 and the cutting surface 56 and penetrates the base portion 52.

[0040] As shown in Figure 3, the cutting surface 53 extends at an angle A1 upward with respect to the loading / unloading direction D10 (i.e., the horizontal direction (see Figure 1)). The lower surface 26 of the feeder body 21 extends parallel to the cutting surface 53. That is, the lower surface 26 of the feeder body 21 also extends at an angle A1 upward with respect to the horizontal direction. In this way, because the lower surface 26 of the feeder body 21 extends parallel to the cutting surface 53, the cutting device 50 can be positioned facing the lower surface 26, allowing the two to be placed closer together. This makes it possible to reduce the vertical size of the component mounting machine 10. In this embodiment, the angle A1 is, for example, 45°.

[0041] The inlet opening 54 has an upper surface periphery 54N and a lower surface periphery 54F. Each periphery 54N and 54F is a region of the inlet opening 54 that extends left and right along the cutting surface 53. The left and right ends of each periphery 54N and 54F are connected to each other. The upper surface periphery 54N is located above the lower surface periphery 54F. That is, the upper surface periphery 54N is located closer to the supply surface 24 (see Figure 1) than the lower surface periphery 54F.

[0042] Similarly, the outlet opening 57 has an upper back peripheral edge 57N and a lower back peripheral edge 57F. Each peripheral edge 57N, 57F is a region of the outlet opening 57 that extends left and right along the cut back surface 56. The left and right ends of each peripheral edge 57N, 57F are connected to each other. The upper back peripheral edge 57N is located above the lower back peripheral edge 57F. That is, the upper back peripheral edge 57N is located closer to the supply surface 24 (see Figure 1) than the lower back peripheral edge 57F.

[0043] As shown in Figure 3, the carrier tape 36 is discharged from the feeder opening 42 via the tape path 28 of the feeder body 21 and the guide-shaped portion 44 of the attachment 40. The guide-shaped portion 44 is curved so that it is displaced backward as it goes downward. As a result, the guide-shaped portion 44 causes the carrier tape 36 discharged from the tape path 28 to protrude in a direction perpendicular to the cutting surface 53 of the cutting device 50.

[0044] Furthermore, the carrier tape 36 passes through the through-hole 55 from the inlet opening 54 facing the feeder opening 42 and protrudes downward from the outlet opening 57. That is, the through-hole 55 communicates with the inlet opening 54 and the outlet opening 57 to define a guide passage for guiding the carrier tape 36 toward the cutting device 50.

[0045] The cutting portion 60 includes a fixed blade 62 and a movable blade 64 disposed opposite to the fixed blade 62. The fixed blade 62 is disposed inside the through-hole 55 of the pedestal portion 52. The sharp lower end of the fixed blade 62 extends in the left-right direction on the cutting back surface 56. Therefore, the upper back surface periphery 57N is formed by the sharp lower end of the fixed blade 62.

[0046] The movable blade 64 is configured to be movable in the cutting direction D21 along the cutting back surface 56. The movable blade 64 extends in the left-right direction beyond the through-hole 55. The movable blade 64 moves in the cutting direction D21 along a pair of rails (not shown) disposed on both the left and right sides of the through-hole 55. At this time, the movable blade 64 displaces the carrier tape 36 protruding downward from the outlet opening 57 toward the upper back surface periphery 57N of the outlet opening 57. Thereafter, the leading end portion 39 of the carrier tape 36 is pinched off by the sharp upper end of the movable blade 64 and the sharp lower end of the fixed blade 62. Thus, by moving the movable blade 64 along the cutting back surface 56, the movable blade 64 can be stably moved. Thereby, the leading end portion 39 of the carrier tape 36 can be surely cut. Furthermore, as described above, the carrier tape 36 protrudes in a direction orthogonal to the cutting surface 53 by the guide-shaped portion 44. Thereby, the fixed blade 62 and the movable blade 64 are orthogonal to the carrier tape 36. Therefore, the leading end portion 39 of the carrier tape 36 can be surely pinched off. The pinched-off leading end portion 39 is accommodated in the tape waste box 19 (see FIG. 1).

[0047] As described above, the carrier tape 36 is a paper tape. Also, for example, in the carrier tape 36 corresponding to relatively small-sized components, a relatively thin thickness may be adopted. In this case, it is difficult for the carrier tape 36 to maintain its own shape. As a result, as shown by the arrow R1 in FIG. 3, after the tip portion 39 of the carrier tape 36 is cut, the carrier tape 36 hangs downward from the feeder opening 42. Note that the downward hanging can occur similarly even if the carrier tape 36 is an embossed tape formed of a soft resin-based material (e.g., polystyrene). As a result, the cut end 38 of the carrier tape 36 is located directly below the contact point 46 between the carrier tape 36 and the guide-shaped portion 44. Further, the cut end 38 is located above the lower surface peripheral edge 54F. That is, the cut end 38 is located within the through-hole 55 in the vertical direction (i.e., within the range E1 of the entrance opening 54 of the through-hole 55).

[0048] As described above, the feeder 20 is attached to and detached from the holding device 12 along the attachment / detachment direction D10 (see FIG. 1) parallel to the horizontal direction. For example, when the feeder 20 is removed from the holding device 12, the feeder 20 moves forward along the removal direction D11 in the attachment / detachment direction D10. As shown in FIG. 3, the vertical distance H2 between the contact point 46 (i.e., the guide-shaped portion 44 of the feeder opening 42) and the cut end 38 indicates the length of the carrier tape 36 hanging downward from the contact point 46. That is, the distance H2 is the same as the distance between the contact point 46 and the upper back surface peripheral edge 57N. On the other hand, the vertical distance H1 between the contact point 46 and the lower surface peripheral edge 54F indicates the size of the vertical space in which the carrier tape 36 can move when the feeder 20 is removed from the holding device 12. In this embodiment, the distance H1 is longer than the distance H2. For this reason, when the feeder 20 is removed from the holding device 12, the cut end 38 passes above the lower surface peripheral edge 54F of the entrance opening 54. That is, when the feeder 20 is removed from the holding device 12, the cut end 38 does not contact the lower surface peripheral edge 54F. Also, when attaching the feeder 20 to the holding device 12, similarly, the cut end 38 passes above the lower surface peripheral edge 54F and moves into the through-hole 55.

[0049] Furthermore, the cut surface 53 and the cut back surface 56 of the base portion 52 are inclined with respect to the loading / unloading direction D10 such that they move downward from the supply surface 24 as the removal direction D11 progresses. That is, the cut surface 53 is inclined such that the lower surface periphery 54F is located below the upper surface periphery 54N. For this reason, compared to a configuration in which the cut surface 53 extends horizontally, for example, the cut end 38 can easily pass above the lower surface periphery 54F.

[0050] Furthermore, in the component mounting machine 10 of this embodiment, since the fixed blade 62 forms the upper back peripheral edge 57N, the cut end 38 of the carrier tape 36 is located relatively high up. For this reason, compared to a configuration in which, for example, the fixed blade 62 forms the lower back peripheral edge 57F, the cut end 38 can easily pass above the lower surface peripheral edge 54F.

[0051] Furthermore, the cut surface 53 and the cut back surface 56 extend at an angle A1 (i.e., 45°) with respect to the loading / unloading direction D10. As a result, the vertical distance between the lower surface periphery 54F and the upper surface periphery 54N becomes relatively large. Therefore, compared to a configuration in which the cut surface 53 is inclined at 30° with respect to the loading / unloading direction D10, for example, the cut end 38 can easily pass above the lower surface periphery 54F.

[0052] (Effects of this embodiment) In the component mounting machine 10 of this embodiment, the cut end 38 is located within the range E1 of the inlet opening 54 in the vertical direction. Therefore, when the feeder 20 is removed from the holding device 12 along the removal direction D11, the cut end 38 passes above the lower surface edge 54F of the inlet opening 54. That is, when the feeder 20 is removed from the holding device 12, the cut end 38 does not come into contact with the lower surface edge 54F. Similarly, when attaching the feeder 20 to the holding device 12, the cut end 38 also passes above the surface edge 54F and moves into the through hole 55. Therefore, when attaching and detaching the feeder 20 to the holding device 12, it is possible to suppress the cut end 38 from coming into contact with and getting entangled with the surface edge 54F. Furthermore, according to the component mounting machine 10 of this embodiment, when attaching and detaching the feeder 20 to the holding device 12, it is not necessary, for example, to reverse the rotation of the sprocket 22 to displace the cut end 38 of the carrier tape 36 upward. Compared to conventional technology, the feeder 20 can be easily attached to and detached from the holding device 12.

[0053] The correspondence in this embodiment is as follows: The lower surface edge 54F is an example of a "surface edge," and the upper back surface edge 57N is an example of a "back surface edge." The device body 51 is an example of a "body."

[0054] (Second Embodiment) Referring to Figure 4, the component mounting machine 10 of the second embodiment will be described. The component mounting machine 10 of this embodiment is equipped with a carrier tape 136 instead of the carrier tape 36 of the first embodiment. The carrier tape 136 is a so-called embossed tape having recesses for accommodating the components 4. In addition, the component mounting machine 10 of this embodiment is equipped with a cutting device 150 instead of the cutting device 50. However, although the cutting device 150 of this embodiment is smaller in the vertical direction than the cutting device 50 of the first embodiment, its basic structure is the same as that of the cutting device 50 of the first embodiment. For example, in the cutting device 150 of this embodiment, the cutting surface 153 and the cutting back surface 156 are inclined at an angle A1 with respect to the loading / unloading direction D10. In this embodiment as well, the angle A1 is 45°. In addition, the cutting section 160 of the cutting device 150 has a fixed blade 162 and a movable blade 164, similar to the cutting section 60 of the cutting device 50 of the first embodiment. The movable blade 164 moves along the cutting surface 156 and toward the fixed blade 162 in the cutting direction D22.

[0055] The carrier tape 136 in this embodiment is an embossed tape and is made of a rigid material (for example, polyethylene terephthalate). Therefore, the carrier tape 136 has higher rigidity than the carrier tape 36 of the first embodiment and can easily maintain its shape. As a result, as shown in Figure 4, even after the tip portion 139 of the carrier tape 136 is cut, the carrier tape 136 does not sag downwards but maintains an orientation extending from the contact point 146 between the carrier tape 136 and the guide-shaped portion 44 toward the upper back peripheral edge 157N. It should be noted that the carrier tape 136 can maintain its orientation not only when it is an embossed tape made of a rigid material, but also when it is a thick paper tape containing relatively large parts. Therefore, even after the tip portion 139 of the carrier tape 136 is cut, the cut end 138 of the carrier tape 136 is located near the upper back peripheral edge 157N.

[0056] Similar to the first embodiment, the cut end 138 of the carrier tape 136 in this embodiment is also located within the through hole 155 of the base portion 152 in the vertical direction (i.e., within the range E2 of the entrance opening 154 of the through hole 155). Furthermore, in this embodiment, the vertical distance H3 between the contact 146 and the lower surface edge 154F is longer than the vertical distance H4 between the contact 146 and the upper back edge 157N. Therefore, for example, when the feeder 20 moves along the removal direction D12, the cut end 138 passes above the lower surface edge 154F. That is, when the feeder 20 is removed from the holding device 12, the cut end 138 does not come into contact with the lower surface edge 154F. Similarly, when attaching the feeder 20 to the holding device 12, the cut end 138 also passes above the lower surface edge 154F and moves into the through hole 155.

[0057] In the component mounting machine 10 of this embodiment, the carrier tape 136 does not hang down even after the leading edge 139 of the carrier tape 136 has been cut. Therefore, the vertical space in which the carrier tape 136 moves when the feeder 20 is loaded and unloaded only needs to be longer than the distance H4. In other words, in this embodiment, the lower surface periphery 154F can be positioned higher than in the first embodiment. As a result, the base portion 152 of the device body 151 can be made smaller in the vertical direction. Therefore, the vertical size of the cutting device 150 is smaller than that of the cutting device 50 in the first embodiment. This makes it possible to reduce the vertical size of the component mounting machine 10 compared to the first embodiment.

[0058] The following points should be noted regarding the component mounting machine 10 described in the embodiment. The multiple rails 13 may be inclined such that they are displaced upward towards the front. In that case, the feeder 20 may be attached to and detached from the holding device 12 at an angle that causes it to be displaced upward towards the front along the multiple rails 13. That is, the attachment and detachment direction does not have to be parallel to the horizontal direction.

[0059] The cutting surface 53 and cutting back surface 56 of the base portion 52 of the cutting device 50 do not need to be inclined at an angle A1 with respect to the loading / unloading direction D10. For example, the cutting surface 53 and cutting back surface 56 may extend parallel to the loading / unloading direction D10. In this case, for example, the cutting surface 53 and cutting back surface 56 may have a first surface located on the side of the removal direction D11 (i.e., forward) with respect to the through hole 55, and a second surface located on the opposite side of the removal direction D11 (i.e., rear) with respect to the through hole 55. The first surface may be located below the second surface. In this case, the cutting portion 60 may cut the carrier tape 36 above the first surface. This allows, for example, when removing the feeder 20, the cut end 38 of the carrier tape 36 to pass above the first surface as the feeder 20 moves in the removal direction D11.

[0060] The lower surface 26 of the feeder body 21 of the feeder 20 does not have to be inclined at an angle A1 with respect to the loading / unloading direction D10. In this case, the lower surface 26 may extend parallel to the loading / unloading direction D10.

[0061] The movable blade 64 of the cutting section 60 may move along the cutting surface 53. In this case, the fixed blade 62 may form the upper surface periphery 54N.

[0062] The movable blade 64 of the cutting section 60 does not necessarily have to move along the back surface 56 of the cut surface. In this case, the movable blade 64 may move, for example, from below to above the fixed blade 62.

[0063] The feeder 20 does not need to have the attachment 40. That is, the feeder 20 does not need to have the guide-shaped portion 44. In this modified example, the carrier tape 36 may protrude downward from the lower end of the tape path 28.

[0064] The feeder 20 does not need to have an attachment 40. In this modified example, the tape path 28 of the feeder body 21 may be curved in a direction perpendicular to the cutting surface 53.

[0065] Angle A1 does not have to be 45°. For example, it could be 60° or 30°.
