Description

TECHNICAL FIELD

[0001] The present application relates to an anvil unit and a component mounting apparatus provided with the anvil unit. BACKGROUND

[0002] Conventionally, a component such as a radial component or an axial component has two lead wires, and the two lead wires are inserted into an insertion hole provided in a substrate. A component mounting apparatus that mounts such a component with lead wires in an inserted manner is provided with an anvil unit. The anvil unit has a lead wire processing portion for processing lead wires that protrude in a direction of a lower surface side of the substrate (see, for example, Patent Literature 1). The lead wire processing portion performs processing such as bending of the lead wires.

[0003] The anvil unit of Patent Literature 1 is provided with a plurality of guide pins that guide the lead wires toward the insertion hole of the substrate, and a plurality of selection levers that selectively move each of the guide pins up and down. Each of the guide pins is inserted into the insertion hole of the substrate from below, and engages with the lead wires located above the substrate. Each of the selection levers is linked to the lower end portion of the guide pin, and is driven by a work cylinder or the like to integrally move each of the guide pins up and down.

[0004] Each of the guide pins moves up and down between a retreat position that retreats below the substrate and a protrusion position that protrudes above the substrate by passing through the insertion hole of the substrate. In a case where three or more selection levers are provided, two selection levers that move up and down are selected in accordance with the interval of the two lead wires guided by the guide pins.

[0007] Patent Literature 1: Japanese Patent Application Laid-Open No. 2007-109849 SUMMARY

[0008] PROBLEMS TO BE SOLVED BY THE INVENTION

[0009] Conventionally, when a component is inserted into a substrate in various orientations, the anvil unit is able to rotate in accordance with the orientation of the component. As a structure of the anvil unit, in a case where the guide pins and the upper ends of the selection levers integrally rotate, on the other hand, the lower end positions of the selection levers are fixed and do not rotate. In this case, the selection levers interfere with each other due to the rotational position of the anvil unit, and thus the anvil unit cannot further rotate. The flexibility of rotation of the anvil unit can be said to still have room for improvement.

[0010] Therefore, an object of the present application is to solve the problems described above, and to provide an anvil unit and a component mounting apparatus provided with the anvil unit, which have improved flexibility of rotation.

That is, even if the anvil body section 20 is rotated in the XY plane, the selection lever driving sections 50, 52, 54, 56, 58 and the second ends 40B, 42B, 44B, 46B, 48B do not rotate, but maintain Figure 4 the relative positional relationship in the XY direction shown in the drawings.

[0165] Returning to Figure 3 , the linking section 32 is a member that links the plurality of guide pins 26 and the first ends 40A, 42A, 44A, 46A, 48A of the plurality of selection levers 28 to the anvil body section 20. The linking section 32 is composed of a cylindrical housing (not shown) that houses the plurality of guide pins 26 and the like and is fixed to the anvil body section 20, but the detailed structure is omitted from the description and the drawings.

[0166] The plurality of guide pins 26 are coupled to the anvil body 20 in a state of being arranged in a row in the X direction as indicated by arrow X2.

[0167] The plurality of guide pins 26 and the first ends 40A, 42A, 44A, 46A, and 48A of the plurality of selector levers 28 rotate integrally with each other through the connecting portion 32 when the anvil body 20 rotates about the rotation axis C in the XY plane as indicated by the arrow XY2. Even when the anvil body 20 rotates integrally with the anvil body 20, the positional relationship in which the guide pins 26 are arranged in a row is maintained.

[0168] The second ends 40B, 42B, 44B, 46B, and 48B of the selector lever 28 are not connected to the anvil body 20 via the connecting portion 32. Therefore, when the anvil body 20 rotates about the rotation axis C, twisting occurs in each selector lever 28, and the selector levers 28 interfere with each other due to the rotational positions of the first ends 40A, 42A, 44A, 46A, and 48A of the selector lever 28, thereby preventing the anvil body 20 from rotating further.

[0169] In the component mounting device 1 of the first embodiment, the arrangement of the plurality of selector levers 28 is studied so as to ensure that the rotation range of the anvil unit 12 is more than 180 degrees, and in particular, the arrangement of the second ends 40B, 42B, 44B, 46B, and 48B is studied. Figure 5 The following figures illustrate this.

[0170] Figure 5 It is a schematic plan view showing the positional relationship in the XY directions between the first ends 40A, 42A, 44A, 46A, and 48A and the second ends 40B, 42B, 44B, 46B, and 48B of the select lever 28 .

[0171] like Figure 5 As shown, the first ends 40A, 42A, 44A, 46A, and 48A are arranged along a row X3 extending in the X direction. As described above, the first ends 40A, 42A, 44A, 46A, and 48A are portions that rotate together with the anvil body 20 (see arrow XY2), and rotate about the rotation axis C of the anvil body 20. In the first embodiment, the first end 44A located in the center of the first ends 40A, 42A, 44A, 46A, and 48A is arranged to coincide with the rotation axis C of the anvil unit 12.

[0172] like Figure 5As shown, the second ends 40B, 42B, 44B, 46B, 48B are arranged at positions offset with respect to the column X3. In Embodiment 1, in particular, the second ends 40B, 42B, 44B, 46B, 48B are alternately arranged as second ends arranged on one side with respect to the column X3 and second ends arranged on the other side with respect to the column X3. More specifically, the second ends 40B, 44B, 48B are arranged on one side (the left side in the paper) with respect to the column X3, and the second ends 42B, 46B are arranged on the other side (the right side in the paper) with respect to the column X3.

[0173] The first ends 40A, 42A, 44A, 46A, 48A have center positions 40C, 42C, 44C, 46C, 48C, respectively. Likewise, the second ends 40B, 42B, 44B, 46B, 48B have center positions 40D, 42D, 44D, 46D, 48D, respectively. In the example shown, the first ends 40A, 42A, 44A, 46A, 48A and the second ends 40B, 42B, 44B, 46B, 48B each have a circular shape, but can have any shape. Figure 5 In the example shown, the first ends 40A, 42A, 44A, 46A, 48A and the second ends 40B, 42B, 44B, 46B, 48B each have a circular shape, but can have any shape.

[0174] Here, a line connecting the center positions 40C, 40D of the first selection lever 40 is set as a center line 40E. Likewise, a line connecting the center positions 42C, 42D is set as a center line 42E, a line connecting the center positions 44C, 44D is set as a center line 44E, a line connecting the center positions 46C, 46D is set as a center line 46E, and a line connecting the center positions 48C, 48D is set as a center line 48E.

[0175] In the component mounting apparatus 1 of Embodiment 1, it is designed so that Figure 5 The rotational position shown is a reference position, and within a total rotation range of 180 degrees of a range of +90 degrees from the reference position and a range of -90 degrees from the reference position, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other at any height position. Thus, the selection levers 28 do not interfere with each other at least within the 180-degree rotation range, and it is possible to secure a rotation range of 180 degrees or more for the anvil unit 12.

[0176] Figure 6A , Figure 6B is a schematic plan view showing a change in position of the selection levers 28 when the anvil unit 12 is rotated by +90 degrees. Figure 6A shows a state in which the anvil unit 12 is rotated by approximately +45 degrees, Figure 6B shows a state in which the anvil unit 12 is rotated by approximately +90 degrees.

[0177] As shown in Figure 6AAs shown, in the state of being rotated by approximately +45 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other when the first ends 40A, 42A, 44A, 46A, 48A are rotated by +45 degrees around the rotation axis C. As shown in FIG. 10, in the state of being rotated by approximately +90 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. In the plan view of FIG. 11, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. Figure 6B As shown, in the state of being rotated by approximately +45 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other when the first ends 40A, 42A, 44A, 46A, 48A are rotated by +45 degrees around the rotation axis C. As shown in FIG. 10, in the state of being rotated by approximately +90 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. In the plan view of FIG. 11, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. Figure 6B In such a plan view, for example, the center lines 40E, 42E appear to overlap each other, but the center lines 40E, 42E are located at positions twisted with respect to each other in the height direction Z and do not cross each other at least until reaching the rotation position of +90 degrees. The same applies to the center lines 44E, 46E with respect to each other and the center lines 44E, 48E with respect to each other. Thus, it is possible to secure the rotation range of 180 degrees from the reference position.

[0178] Figure 7A , Figure 7B is a schematic plan view showing the position change of the selection lever 28 when the anvil unit 12 is rotated by 90 degrees. Figure 7A As shown, in the state of being rotated by approximately -45 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other when the first ends 40A, 42A, 44A, 46A, 48A are rotated by -45 degrees around the rotation axis C. As shown in FIG. 16, in the state of being rotated by approximately -90 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. In the plan view of FIG. 17, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. Figure 7B As shown, in the state of being rotated by approximately -45 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other when the first ends 40A, 42A, 44A, 46A, 48A are rotated by -45 degrees around the rotation axis C. As shown in FIG. 16, in the state of being rotated by approximately -90 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. In the plan view of FIG. 17, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either.

[0179] In such a plan view, for example, the center lines 40E, 42E appear to overlap each other, but the center lines 40E, 42E are located at positions twisted with respect to each other in the height direction Z and do not cross each other at least until reaching the rotation position of +90 degrees. The same applies to the center lines 44E, 46E with respect to each other and the center lines 44E, 48E with respect to each other. Thus, it is possible to secure the rotation range of 180 degrees from the reference position. Figure 7A As shown, in the state of being rotated by approximately -45 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other when the first ends 40A, 42A, 44A, 46A, 48A are rotated by -45 degrees around the rotation axis C. As shown in FIG. 16, in the state of being rotated by approximately -90 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. In the plan view of FIG. 17, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. Figure 7B As shown, in the state of being rotated by approximately -45 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other when the first ends 40A, 42A, 44A, 46A, 48A are rotated by -45 degrees around the rotation axis C. As shown in FIG. 16, in the state of being rotated by approximately -90 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. In the plan view of FIG. 17, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. Figure 7B In such a plan view, for example, the center lines 40E, 42E appear to overlap each other, but the center lines 40E, 42E are located at positions twisted with respect to each other in the height direction Z and do not cross each other at least until reaching the rotation position of +90 degrees. The same applies to the center lines 44E, 46E with respect to each other and the center lines 44E, 48E with respect to each other. Thus, it is possible to secure the rotation range of 180 degrees from the reference position.

[0180] As shown, in the state of being rotated by approximately -45 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other when the first ends 40A, 42A, 44A, 46A, 48A are rotated by -45 degrees around the rotation axis C. As shown in FIG. 16, in the state of being rotated by approximately -90 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. In the plan view of FIG. 17, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. Figures 6A-7B As shown, in the state of being rotated by approximately -45 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other when the first ends 40A, 42A, 44A, 46A, 48A are rotated by -45 degrees around the rotation axis C. As shown in FIG. 16, in the state of being rotated by approximately -90 degrees, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either. In the plan view of FIG. 17, the center lines 40E, 42E, 44E, 46E, 48E do not cross each other either.

[0181] Since the two selection levers 28 are moved up and down when guiding the leads of the component 3, the positional relationship in the up-and-down direction of the center lines 40E, 42E, 44E, 46E, 48E changes from each other, but the design is made also considering such up-and-down movement of the selection lever 28. That is, it is designed so that, as shown in Figures 6A-7B , the center lines 40E, 42E, 44E, 46E, 48E do not cross each other within a prescribed rotation range of 180 degrees.

[0182] In addition, each selection lever 28 uses a lever that is long in the Z direction and short (thin) in the XY direction. For example, in the case where the center lines 40E, 42E, 44E, 46E, 48E do not cross each other at the rotation positions of +90 degrees and -90 degrees as shown in Figure 6B , Figure 7B , there is also a case where the selection levers 28 slightly contact each other due to the height positions. In such a case, the selection levers 28 are elastically deformed and the like and can ignore the influence brought by the contact, thereby becoming a design that can secure the rotation range of the anvil unit 12 to be 180 degrees or more.

[0183] In the above structure, five guide pins 26 and selection levers 28 (five groups) are respectively provided, and two groups that are moved up and down are selected according to the pitch of the leads of the component 3. Thereby, it is also possible to cope with a case where the number of modes of the pitch of the leads is, for example, four. In a case where the number of modes of the pitch is small, by appropriately detaching the group of the guide pin 26, the selection lever 28, and the selection lever driving section 30 from the structure of Embodiment 1, it is also possible to simplify the structure of the insertion guide mechanism 24.

[0184] For example, as shown in Figure 8 , it is also possible to provide a structure in which the group of the first selection lever 40 and the first selection lever driving section 50 is detached. According to the structure shown in Figure 8 , it is possible to cope with a case where the number of modes of the pitch is, for example, three. In addition, as shown in Figure 9 , it is also possible to provide a structure in which the group of the fifth selection lever 48 and the fifth selection lever driving section 58 is detached in addition to the group of the first selection lever 40 and the first selection lever driving section 50. According to the structure shown in Figure 9 , it is possible to cope with a case where the number of modes of the pitch is, for example, two. Note that, in the structure shown in Figure 9 , it is also possible to further omit, for example, the second selection lever 42 and the second selection lever driving section 52, and to retain the guide pin 26 corresponding to the omitted second selection lever 42 and to keep the guide pin 26 in a state of being always raised. In such a case, it is also possible to cope with a case where the number of modes of the pitch is two.

[0185] In the component mounting apparatus 1 of the first embodiment, the anvil unit 12 is rotated in a range of 180 degrees or more, and the anvil body 20 and the hose 22 ( Figure 1 ) connection structure was also studied. Specifically, using Figure 10 Provide explanation.

[0186] Figure 10 It is a schematic perspective view showing the connection structure 34 that connects the anvil body 20 and the hose 22 .

[0187] like Figure 10 As shown, the connecting structure 34 includes a first connecting portion 36 and a second connecting portion 38. The first connecting portion 36 and the second connecting portion 38 are connected to each other, and the first connecting portion 36 is fixed to the anvil body 20, and the second connecting portion 38 is fixed to the hose 22. A storage space (not shown) for storing wire scraps is formed inside the first connecting portion 36 and the second connecting portion 38.

[0188] In the first embodiment, the first connection portion 36 and the second connection portion 38 are connected so as to be rotatable relative to each other. Specifically, the first connection portion 36 and the second connection portion 38 are connected so as to be rotatable relative to each other about a rotation axis S that is different from the rotation axis C of the anvil body 20. With this structure, when the anvil body 20 rotates about the rotation axis C as indicated by arrow XY2, the first connection portion 36 and the second connection portion 38 can also rotate relative to each other in a manner that absorbs the effects of the rotation of the anvil body 20. This suppresses unnecessary rotation of the hose 22, thereby preventing breakage of the hose 22.

[0189] As described above, the anvil unit 12 of the present embodiment is provided with the anvil main body 20, the plurality of guide pins 26, the plurality of selection levers 28, the plurality of selection lever driving portions 30, and the linking portion 32. The anvil main body 20 has the lead wire processing portion 18 that processes the lead wires of the component 3 inserted into the insertion hole 17 of the substrate 2, and has a rotation function. The plurality of guide pins 26 are inserted into the insertion hole 17 of the substrate 2, and guide the lead wires of the component 3 toward the insertion hole 17. The plurality of selection levers 28 are provided in correspondence with the plurality of guide pins 26, respectively, and each has a first end 40A, 42A, 44A, 46A, 48A that is coupled to the guide pin 26, and a second end 40B, 42B, 44B, 46B, 48B. The plurality of selection lever driving portions 30 are provided in correspondence with the plurality of selection levers 28, respectively, and are coupled to the second ends 40B, 42B, 44B, 46B, 48B of the selection levers 28, and move the selection levers 28 up and down. The linking portion 32 links the plurality of guide pins 26 and the first ends 40A, 42A, 44A, 46A, 48A of the plurality of selection levers 28 to the anvil main body 20 in a manner that rotates in conjunction with the rotation of the anvil main body 20. In this structure, the second ends 40B, 42B, 44B, 46B, 48B of the plurality of selection levers 28 are fixed in position by the selection lever driving portions 30. Also, the positions of the second ends 40B, 42B, 44B, 46B, 48B are set so that the center lines 40E, 42E, 44E, 46E, 48E that link the center positions 40C, 42C, 44C, 46C, 48C of the first ends 40A, 42A, 44A, 46A, 48A of the plurality of selection levers 28 and the center positions 40D, 42D, 44D, 46D, 48D of the second ends 40B, 42B, 44B, 46B, 48B do not cross each other at any of the height positions during the period in which the rotational positions of the first ends 40A, 42A, 44A, 46A, 48A of the plurality of selection levers 28 are within a prescribed range (180 degrees in the embodiment 1).

[0190] According to such a structure, it is possible to prevent interference of the selection levers 28 with each other, and to set the range of rotation of the anvil main body 20 to be, for example, 180 degrees or more, thereby making it possible to improve the flexibility of the rotation of the anvil unit 12. As a result, it is possible to increase the variation of the direction in which the component 3 can be inserted with respect to the substrate 2, thereby making it possible to expand the range of rotation that the anvil unit 12 can cope with. Also, it is possible to determine the positions of the second ends 40B, 42B, 44B, 46B, 48B based on the center positions 40C, 42C, 44C, 46C, 48C of the first ends 40A, 42A, 44A, 46A, 48A and the center positions 40D, 42D, 44D, 46D, 48D of the second ends 40B, 42B, 44B, 46B, 48B, thereby making it possible to facilitate the design.

[0191] Note that it is not limited to the case where the range of rotation of the anvil main body 20 is ensured to be 180 degrees or more, and it can be ensured to be any other angular range (for example, less than 180 degrees). Also, it is not limited to the case where the center lines 40E, 42E, 44E, 46E, 48E do not cross each other, and it can be designed so that the lines connecting any position of the first ends 40A, 42A, 44A, 46A, 48A and any position of the second ends 40B, 42B, 44B, 46B, 48B do not cross each other.

[0192] Also, in the anvil unit 12 of the present embodiment, the guide pins 26, the selection rods 28, and the selection rod 28 drive portions are each provided with five, and the first ends 40A, 42A, 44A, 46A, 48A of the five selection rods 28 are arranged in a column X3 when viewed along the rotation axis C of the anvil main body 20.

[0193] According to such a structure, by providing five selection rods 28, in the case where the pitch of the insertion holes 17 of the substrate 2 changes, it is also possible to cope with multiple pitches by selectively moving the selection rods 28 up and down. Also, in the case where interference of the selection rods 28 with each other is likely to occur when the number of selection rods 28 increases, by previously setting the positions of the second ends 40B, 42B, 44B, 46B, 48B of the selection rods 28, it is possible to prevent interference of the selection rods 28 with each other.

[0194] Also, in the anvil unit 12 of the present embodiment, the first end 44A, which is one of the first ends 40A, 42A, 44A, 46A, 48A of the five selection rods 28, is located at a position overlapping the rotation axis C of the anvil main body 20.

[0195] According to such a structure, by providing one selection rod 28 that does not rotate in synchronization with the anvil main body 20, it is possible to use it as a selection rod 28 that becomes a reference.

[0196] Also, in the anvil unit 12 of the present embodiment, the second end 44B corresponding to the first end 44A overlapping the rotation axis C is disposed at a position offset from the first end 44A when viewed along the rotation axis C.

[0197] According to such a structure, by staggering the position of the first end 44A overlapping the rotation axis C and the second end 44B corresponding to the first end 44A, it is possible to effectively prevent interference of the selection rods 28 with each other.

[0198] Further, in the anvil unit 12 of the present embodiment, the second ends 40B, 42B, 44B, 46B, 48B of the five selection levers 28 are disposed on either one side or the other side with respect to the column X3 of the first ends 40A, 42A, 44A, 46A, 48A when viewed in plan along the rotation axis C of the anvil main body portion 20.

[0199] According to such a structure, by disposing the second ends 40B, 42B, 44B, 46B, 48B in an offset manner with respect to the column X3 of the first ends 40A, 42A, 44A, 46A, 48A, it is possible to perform design such that the second ends 40B, 42B, 44B, 46B, 48B are dispersedly disposed in good balance.

[0200] Further, in the anvil unit 12 of the present embodiment, the second ends 40B, 42B, 44B, 46B, 48B of the five selection levers 28 are alternately provided with second ends (40B, 44B, 48B) disposed on one side with respect to the column X3 of the first ends 40A, 42A, 44A, 46A, 48A, and second ends (42B, 46B) disposed on the other side with respect to the column X3 of the first ends 40A, 42A, 44A, 46A, 48A.

[0201] According to such a structure, it is possible to perform design such that the second ends 40B, 42B, 44B, 46B, 48B are dispersedly disposed in good balance.

[0202] Further, in the anvil unit 12 of the present embodiment, the lead processing portion 18 processes the lead of the component 3 by bending the lead of the component 3.

[0203] According to such a structure, it is possible to assemble the component 3 to the substrate 2 with high precision.

[0204] Further, the component mounting apparatus 1 of the present embodiment is provided with: a substrate positioning portion 6 that positions the substrate 2 at a prescribed mounting position; a mounting head 10 that picks up the component 3 and inserts the lead of the component 3 into the substrate 2 positioned at the mounting position; and an anvil unit 12 that has a lead processing portion 18 that processes the lead of the component 3.

[0205] According to such a structure, it is possible to achieve the same effects as the anvil unit 12 described above.

[0206] (Embodiment 2)

[0207] An anvil unit of Embodiment 2 of the present application and a component mounting apparatus using the same will be described. Note that in Embodiment 2, points different from Embodiment 1 will mainly be described, and descriptions repeated from Embodiment 1 will be omitted.

[0208] In Embodiment 2, the configuration of the selection rods is different from that of Embodiment 1. In particular, in Embodiment 2, the extension directions of the selection rods at the reference positions are all aligned with the up-down direction, unlike in Embodiment 1.

[0209] Figure 11 is a schematic plan view of the plurality of selection rods 62 in the anvil unit 60 of Embodiment 2. Figure 12 is a schematic plan view showing the plurality of selection rod driving portions 64 and the second ends 70B, 72B, 74B, 76B, 78B of the selection rods 62 connected to the respective selection rod driving portions 64.

[0210] Figure 11 The plurality of selection rods 62 shown include a first selection rod 70, a second selection rod 72, a third selection rod 74, a fourth selection rod 76, and a fifth selection rod 78.

[0211] As shown in Figure 11 As shown in a plan view of the selection rods 70, 72, 74, 76, 78 at the reference positions along the rotation axis C, the first ends 70A, 72A, 74A, 76A, 78A and the second ends 70B, 72B, 74B, 76B, 78B overlap with each other, respectively. Specifically, the first end 70A and the second end 70B overlap, and a center line 70E connecting the center position of the first end 70A and the center position of the second end 70B also overlaps. Similarly, the first end 72A, the second end 72B, and a center line 72E overlap, the first end 74A, the second end 74B, and a center line 74E overlap, the first end 76A, the second end 76B, and a center line 76E overlap, and the first end 78A, the second end 78B, and a center line 78E overlap.

[0212] Figure 12 The plurality of selection rod driving portions 64 shown include a first selection rod driving portion 80, a second selection rod driving portion 82, a third selection rod driving portion 84, a fourth selection rod driving portion 86, and a fifth selection rod driving portion 88.

[0213] The first selection rod driving portion 80 has a first driving body portion 80A and a first connecting portion 80B, and the second end 70B is connected to the first connecting portion 80B. Similarly, the second selection rod driving portion 82 has a second driving body portion 82A and a second connecting portion 82B, and the second end 72B is connected to the second connecting portion 82B, the third selection rod driving portion 84 has a third driving body portion 84A and a third connecting portion 84B, and the second end 74B is connected to the third connecting portion 84B, the fourth selection rod driving portion 86 has a fourth driving body portion 86A and a fourth connecting portion 86B, and the second end 76B is connected to the fourth connecting portion 86B, and the fifth selection rod driving portion 88 has a fifth driving body portion 88A and a fifth connecting portion 88B, and the second end 78B is connected to the fifth connecting portion 88B.

[0214] In Figure 12 the example shown, the height positions in the Z direction of the connection portions 80B, 82B, 84B, 86B, 88B are staggered so as not to interfere with each other, but are not limited to such a case, and connection portions of different planar shapes from those of Embodiment 1 can be used and arranged at the same height position.

[0215] In Figure 11 , Figure 12 the arrangement of the selection levers 70, 72, 74, 76, 78 shown, it is also possible to secure a rotation range of the anvil unit 60 of 180 degrees or more. Specifically, the arrangement is such that Figure 13 , Figure 14 is explained.

[0216] Figure 13 is a schematic plan view showing the positional changes of the selection levers 70, 72, 74, 76, 78 when the anvil unit 60 is rotated by +90 degrees, Figure 14 is a schematic plan view showing the positional changes of the selection levers 70, 72, 74, 76, 78 when the anvil unit 60 is rotated by -90 degrees.

[0217] As Figure 13 shown, in the state rotated by +90 degrees from the reference position, the center lines 70E, 72E, 74E, 76E, 78E do not cross each other. Likewise, as Figure 14 shown, in the state rotated by -90 degrees from the reference position, the center lines 70E, 72E, 74E, 76E, 78E do not cross each other.

[0218] As Figure 13 , Figure 14 shown, the arrangement is such that the center lines 70E, 72E, 74E, 76E, 78E do not cross each other within a prescribed rotation range of 180 degrees, so that it is possible to secure a rotation range of the anvil unit 60 of 180 degrees or more. As with Embodiment 1, the arrangement is such that the up-and-down movement of each selection lever 62 is also taken into account, and the arrangement is such that the center lines 70E, 72E, 74E, 76E, 78E do not cross each other within a prescribed rotation range of 180 degrees, even when each selection lever 62 is at an arbitrary height position.

[0219] As described above, in the anvil unit 60 of Embodiment 2, the positions of the second ends 70B, 72B, 74B, 76B, 78B of the five selection levers 62 are set so that the center lines 70E, 72E, 74E, 76E, 78E connecting the center positions of the first ends 70A, 72A, 74A, 76A, 78A and the center positions of the second ends 70B, 72B, 74B, 76B, 78B of the respective selection levers 62 do not cross each other at any height position during the period in which the rotational positions of the first ends 70A, 72A, 74A, 76A, 78A are located within the prescribed 180-degree range.

[0220] According to such a structure, it is possible to prevent the selection levers 62 from interfering with each other, and to set the range of rotation of the anvil main body portion 20 to 180 degrees or more, thereby making it possible to improve the flexibility of rotation of the anvil unit 60. As a result, it is possible to increase the variation in the direction in which the member 3 can be inserted with respect to the substrate 2, thereby making it possible to expand the range of rotation that the anvil unit 60 can cope with. In addition, it is possible to determine the positions of the second ends 70B, 72B, 74B, 76B, 78B based on the center positions of the first ends 70A, 72A, 74A, 76A, 78A and the center positions of the second ends 70B, 72B, 74B, 76B, 78B, thereby making it possible to easily design.

[0221] When comparing Embodiments 1 and 2 described above, in Embodiment 2, it is possible to ensure a larger range of rotation of the selection levers 62, whereas in Embodiment 1, as shown in FIG. 6, the same shapes of the connecting portions 50B, 52B, 54B, 56B are used and are arranged at the same height positions. Therefore, it is possible to easily realize by improvement or conversion of the existing model. Figure 4

[0222] The above describes the present application by citing the above-described embodiments, but the present application is not limited to the above-described embodiments. For example, in Embodiments 1 and 2, the case in which five selection levers 28, 62 are respectively provided is described, but it is not limited to such a case, and it is possible to provide at least two selection levers, at least two guide pins, and at least two selection lever driving portions as shown in FIG. 7. Figure 9

[0223] ​​Further, in the case where the selection levers 28, 62 are arranged in a column along the column X3, at least three selection levers 28, 62 can be provided. In this case, as in Embodiments 1, 2, the first ends of the at least three selection levers 28, 62 can be arranged in a column along the column X3 when viewed along the rotation axis C of the anvil main body portion 20, and any one of the first ends can be arranged at a position overlapping the rotation axis C of the anvil main body portion 20. Further, in this case, as in Embodiment 1, the second end corresponding to the first end overlapping the rotation axis C can be arranged at a position offset from the first end when viewed along the rotation axis C. Further, in this case, as in Embodiment 1, the second ends of the at least three selection levers 28 can be arranged on either one of the one side and the other side with respect to the column X3 of the first ends of the selection levers 28, 62 when viewed along the rotation axis C of the anvil main body portion 20. Further, in this case, as in Embodiment 1, the second ends of the at least three selection levers 28 can be alternately provided as the second end arranged on the one side with respect to the column X3 of the first ends and the second end arranged on the other side with respect to the column X3 of the first ends.
