[0064] According to such a structure, by making the stopper movable, it is possible to prevent the rotating member from rotating without limit, and the movable range of the rotating member can be set to more than 360 degrees, compared with the case where the stopper is fixed. Thus, the movable range of the anvil unit can be expanded, and processing such as bending the lead can be performed according to various orientations of the component.

[0065] According to a second aspect of the present invention, there is provided an anvil unit as described in the first aspect, wherein the anvil unit is further provided with a movement limiting member, the movement limiting member limiting the movement of the stopper in a direction deviating from the movement range between the first stop position and the second stop position. According to such a structure, by providing the movement limiting member, the movable range of the rotating member can be set to more than 360 degrees, and the rotating member can also be more reliably prevented from rotating without restriction.

[0066] According to a third aspect of the present invention, there is provided an anvil unit as described in the second aspect, wherein the movement limiting member is a member having a groove or a hole for inserting a part of the stopper, and the movement of the stopper is limited by making the groove or the hole have a closed shape. According to such a structure, the movement of the stopper can be limited with a simple structure.

[0067] According to a fourth aspect of the present invention, there is provided an anvil unit as described in the third aspect, wherein the slot or hole is in an arc shape, and the stopper is rotatably moved between the first stop position and the second stop position. According to such a structure, compared with a case where the slot or hole is in a straight line shape, when a force applying member is provided to apply force to the stopper toward the reference position, it is possible to easily return the stopper to the reference position.

[0068] According to a fifth aspect of the present invention, there is provided an anvil unit as described in the third aspect, wherein the slot or hole is in a straight line shape, and the stopper moves linearly between the first stop position and the second stop position. According to such a structure, the structure can be simplified compared to the case where the slot or hole is in an arc shape.

[0069] According to the sixth aspect of the present invention, there is provided an anvil unit as described in any one of the first to fifth aspects, wherein the anvil unit further comprises a force-applying member, the force-applying member applies force to the stopper toward a predetermined reference position. According to such a structure, by applying force to the stopper in such a manner as to return the stopper to the reference position, the position at which the rotating member and the stopper begin to abut against each other can be made constant, and the movement of the stopper can be stabilized.

[0070] According to a seventh aspect of the present invention, there is provided the anvil unit described in the sixth aspect, wherein the reference position is located between the first stop position and the second stop position. With such a structure, the stopper can be moved in two directions relative to the reference position, and the movement of the stopper can be stabilized.

[0071] According to the eighth aspect of the present invention, there is provided an anvil unit as described in any one of the first to seventh aspects, wherein the anvil unit further comprises: a first sensor for detecting a state in which the rotating member abuts against the stopper; and a second sensor for detecting a state in which the stopper abuts against the rotating member at the first stop position side and a state in which the stopper abuts against the rotating member at the second stop position side. According to such a structure, the position of the rotating member can be determined more accurately based on the detection results of both the first sensor and the second sensor.

[0072] According to a ninth aspect of the present invention, there is provided the anvil unit described in any one of the first to eighth aspects, wherein the lead processing section processes the lead by bending the lead. With such a structure, the lead of the component can be bent and the component can be mounted on a substrate.

[0073] According to the tenth embodiment of the present invention, a component mounting device is provided, wherein the component mounting device comprises: a substrate positioning portion, which positions a substrate at a specified mounting position; a mounting head, which picks up a component and inserts a lead of the component into the substrate positioned at the mounting position; and an anvil unit, which has a lead processing portion for processing the lead of the component.

[0074] According to such a structure, the same effect as the anvil unit of the first to ninth aspects can be achieved.

[0075] Hereinafter, exemplary embodiments of the anvil unit and the component mounting device including the anvil unit of the present invention will be described with reference to the drawings. The present invention is not limited to the specific configurations of the following embodiments, and configurations based on the same technical concept are also included in the present invention.

[0076] (Implementation Method)

[0077] First, refer to Figure 1 A component mounting device according to an embodiment of the present invention is described. The component mounting device 1 is a device for mounting a component 3 on a substrate 2 by inserting it. Hereinafter, the conveying direction horizontal to the substrate 2 is referred to as the X direction, the direction orthogonal to the X direction in the horizontal plane is referred to as the Y direction, and the direction perpendicular to the XY plane, that is, the up-down direction (vertical direction) is referred to as the Z direction.

[0078] like Figure 1 As shown, the component mounting device 1 includes a plurality of feeders 4, a substrate positioning unit 6, a control unit 8, a mounting head 10, an anvil unit 12, a first drive mechanism 14, and a second drive mechanism 16. Figure 1 Schematically illustrates the components of the component mounting device 1 .

[0079] The feeder 4 is a component supply unit that receives the components 3 with leads. Figure 1 As shown, a plurality of feeders 4 are provided and arranged along the X direction. A plurality of components 3 are accommodated in each feeder 4. The components may also be referred to as "components with leads". Component 3 may be any electronic component as long as it is a radial component, an axial component or other component having leads. In the present embodiment, component 3 is a radial component.

[0080] The substrate positioning portion 6 is a member for positioning the substrate 2. The substrate positioning portion 6 is a member for positioning the substrate 2. Figure 1 An XY table is used to transport the substrate 2 in the X and Y directions as shown by arrows X1 and Y1 and to position the substrate 2 at a predetermined mounting position. Figure 1 2 shows a state where the substrate 2 is positioned at the mounting position. The description and illustration of the driving mechanism for driving the substrate positioning portion 6 are omitted.

[0081] The control unit 8 controls the operation of each component of the component mounting device 1. The control unit 8 is electrically connected to each component of the component mounting device 1 via wiring and the like. The control unit 8 is constituted by, for example, a microcomputer.

[0082] The mounting head 10 is a head for inserting the lead wires of the component 3 into the insertion hole 17 of the substrate 2 positioned by the substrate positioning portion 6. The mounting head 10 is arranged above the substrate positioning portion 6, and inserts the lead wires of the component 3 from above with respect to the insertion hole 17 of the substrate 2. The mounting head 10 has a pair of pick-up claws 10A for picking up the component 3. The mounting head 10 including the pick-up claws 10A is driven by the first drive mechanism 14.

[0083] The first driving mechanism 14 has the following features: Figure 1 The arrow Z1 and the arrow XY1 indicate the function of linearly moving the mounting head 10 in the Z direction and the function of rotationally moving the mounting head 10 in the XY plane.

[0084] The anvil unit 12 is a unit for processing the lead wires of the component 3 inserted into the insertion hole 17 of the substrate 2 to mount the component 3 on the substrate 2. The anvil unit 12 is arranged below the substrate positioning portion 6 and processes the lead wires of the component 3 from below. The anvil unit 12 is driven by the second drive mechanism 16.

[0085] The second driving mechanism 16 has the following features: Figure 1 The arrow Z2 and the arrow XY2 indicate the function of linearly moving the anvil unit 12 in the Z direction and the function of rotationally moving the anvil unit 12 in the XY plane.

[0086] The anvil unit 12 includes a wire processing portion 18 , an anvil body portion 20 , a cable 22 , and a rotating member 24 .

[0087] The lead processing portion 18 is a member for processing the lead wire of the processing component 3. The lead processing portion 18 of this embodiment has a cutting blade for nailing and cutting the lead wire of the component 3. The lead processing portion 18 is provided upright on the anvil body portion 20.

[0088] The anvil body 20 is a member constituting the main body of the anvil unit 12, and the lead processing portion 18 is erected on the upper surface of the anvil body 20. In addition to the lead processing portion 18, a cable 22 and a rotating member 24 are connected to the anvil body 20.

[0089] The cable 22 is a cable connected to the anvil body 20. The cable 22 of this embodiment is a cable for sending an electrical signal of a strain sensor (not shown) to the control unit 8, and the strain sensor is used to determine whether the cutting blade of the lead processing unit 18 has normally nailed the component 3. Such a cable 22 for a strain sensor is provided, for example, when the component 3 is radial.

[0090] The rotating member 24 is a rotating member attached to the bottom surface side of the anvil body 20. As the anvil body 20 rotates in the XY plane, the rotating member 24 rotates integrally with the anvil body 20 and the lead processing part 18 in the XY plane. The rotating member 24 of this embodiment is provided with a protrusion 26 for limiting rotation.

[0091] The protrusion 26 is a portion for abutting against the limiter 28 described later to limit the rotation of the rotating member 24 and the anvil body 20. The protrusion 26 has a shape that protrudes radially outward from the outer periphery of the rotating member 24. The rotatable range of the rotating member 24 and the anvil body 20 is limited by the protrusion 26 and the limiter 28, thereby preventing the cable 22 from breaking. It should be noted that in the component mounting device 1 of the present embodiment, the rotation of the anvil body 20 is controlled by the control unit 8, and the rotatable range of the anvil body 20 is limited by software, thereby preventing the cable 22 from breaking. In addition to this software limitation, the limiter 28 is provided as a mechanical limitation, thereby more reliably preventing the cable 22 from breaking.

[0092] exist Figure 1 In the figure, the stopper 28 and its peripheral components that come into contact with the protruding portion 26 are omitted from illustration, and the stopper 28 and its peripheral components will be described later.

[0093] use Figure 2 , a method for manufacturing a component mounting substrate in which components 3 are mounted on a substrate 2 using the component mounting apparatus 1 having the above-described structure will be described. Figure 2 It is a flowchart showing an example of a method of manufacturing a component-mounted substrate using the component mounting apparatus 1 . Figure 2 Each step in is executed by the control unit 8. Figure 2 , main steps for manufacturing a component mounting substrate are shown, and illustration and description of other steps are omitted.

[0094] like Figure 2 As shown, firstly, a substrate positioning step (step S1) is performed. Specifically, Figure 1 In the component mounting apparatus 1 shown, the substrate 2 is conveyed in the X direction and the Y direction using the substrate positioning portion 6 and the substrate 2 is positioned at a predetermined mounting position.

[0095] Next, a picking-up step (step S2 ) is performed. Specifically, the mounting head 10 is driven by using the first driving mechanism 14 , so that the mounting head 10 picks up the component 3 accommodated in the feeder 4 .

[0096] Specifically, the substrate positioning unit 6 is driven to move to a mounting position where the component 3 can be inserted into the substrate 2, and the leads of the component 3 held by the mounting head 10 are inserted into the insertion holes 17 of the substrate 2 from above.

[0097] As described above, the mounting head 10 has a function of rotating in the XY plane by the first drive mechanism 14, and can freely change the orientation of the component 3. Therefore, the component 3 can be inserted into the substrate 2 in various orientations.

[0098] Next, a lead processing step (step S4) is performed. Specifically, the anvil unit 12 is driven by the second drive mechanism 16, so that the lead of the component 3 inserted into the substrate 2 is pinned to the lead processing portion 18 of the anvil unit 12, and the lower end of the lead is cut. Thus, the component 3 is mounted on the substrate 2 in a state where the lead of the component 3 is bent.

[0099] As described above, the anvil unit 12 also has the function of rotating in the XY plane by the second drive mechanism 16, similarly to the mounting head 10. Since the orientations of the components 3 inserted into the substrate 2 are various, the anvil unit 12 can be rotated in the same manner, so that the leads of the components 3 can be bent in a desired direction according to the orientations of the components 3.

[0100] On the other hand, the anvil unit 12 is provided with a cable 22 connected to the anvil body 20, so that the rotatable range of the anvil body 20 is limited in order to prevent the cable 22 from breaking. In the present embodiment, the rotatable range of the anvil body 20 is limited, and a mechanical design (such as a stopper 28) is also performed so that the lead wires of the components 3 can be processed according to the orientation of various components 3. The details will be described later.

[0101] Next, a reflow step (step S5 ) is performed in a state where the component 3 is mounted on the substrate 2 . Thus, the component 3 is soldered to the substrate 2 and the component 3 is mounted on the substrate 2 .

[0102] By executing the above steps S1 to S5, a component mounted substrate in which the component 3 is mounted on the substrate 2 is manufactured. By sequentially executing steps S1 to S5 for a plurality of substrates 2, mass production of the component mounted substrate is performed.

[0103] Next, use Figure 3A to Figure 3C Next, the peripheral structures of the rotating member 24 and the stopper 28 for limiting the rotatable range of the anvil body 20 will be described.

[0104] Figure 3A to Figure 3C The three-dimensional view, side view, and top view respectively show the peripheral structure of the rotating member 24 and the stopper 28. Figure 3A to Figure 3CThe anvil body portion 20 and the lead processing portion 18 are omitted in the figure.

[0105] like Figure 3A to Figure 3C As shown, a stopper 28 is provided at a position adjacent to the rotating member 24. Also, as peripheral structures of the rotating member 24 and the stopper 28, a movement restricting member 30, a biasing member 32, a first sensor 34, and a second sensor 36 are provided.

[0106] The stopper 28 is a member for abutting against the protrusion 26 of the rotating member 24 to restrict the movement of the rotating member 24. The stopper 28 has an abutment portion 37 that abuts against the protrusion 26. Figure 3A to Figure 3C In the embodiment, the protrusion 26 does not contact the contact portion 37, and the rotational movement of the rotating member 24 is not restricted. That is, the rotating member 24 can rotate in both the first rotation direction P1 and the second rotation direction P2. The first rotation direction P1 is set as the forward rotation direction, and the second rotation direction P2 is set as the reverse rotation direction. Figure 5A to Figure 5C and Figure 6A to Figure 6C A state in which the protruding portion 26 and the contact portion 37 are in contact with each other will be described.

[0107] like Figure 3A , Figure 3B As shown, the stopper 28 of this embodiment has a rotation shaft 38. The rotation shaft 38 passes through the movement restricting member 30. The stopper 28 can rotate in the first rotation direction Q1 and the second rotation direction Q2 with the rotation shaft 38 as the rotation center.

[0108] The movement restricting member 30 restricts the movement range of the stopper 28 and supports the stopper 28. The movement restricting member 30 has a hole 40 for restricting the movement range of the stopper 28. The hole 40 of this embodiment is a through hole that penetrates the movement restricting member 30 in the thickness direction.

[0109] A rod-shaped insertion portion 41 connected to the contact portion 37 of the stopper 28 is inserted into the hole 40. The insertion portion 41 moves in an arc shape along the hole 40 as the stopper 28 rotates.

[0110] like Figure 3B As shown, the hole 40 has a shape that is closed in both the first rotation direction Q1 and the second rotation direction Q2 of the stopper 28. Thus, the movement range of the stopper 28 connected to the insertion portion 41 is limited in both the first rotation direction Q1 and the second rotation direction Q2.

[0111] use Figure 4 The movable range of the stopper 28 will be described. Figure 4 It is from Figure 3B The same side view of the stopper 28 is shown in the schematic diagram. Figure 4As shown, if Figure 3A to Figure 3C The rotation position of the stopper 28 shown is set as the reference position A, and the stopper 28 can rotate from the reference position A in the direction toward the first rotation direction Q1, P1 to the first stop position B1. On the other hand, the stopper 28 can rotate from the reference position A in the direction toward the second rotation direction P2, Q2 to the second stop position B2.

[0112] At the first stop position B1, the insertion portion 41 of the stopper 28 abuts against the movement limiting member 30 at one end of the hole 40, thereby limiting further rotation in the first rotation direction Q1. At the second stop position B2, the insertion portion 41 abuts against the movement limiting member 30 at the other end of the hole 40, thereby limiting further rotation in the second rotation direction Q2. The stopper 28 can only move between the first stop position B1 and the second stop position B2.

[0113] return Figure 3A to Figure 3C , the insertion portion 41 of the stopper 28 is connected to one end of the force member 32. The force member 32 of this embodiment is a spring, and has a force to stretch the insertion portion 41. Since the hole 40 through which the insertion portion 41 passes is an arc shape bent in a direction away from the force member 32, the farther the insertion portion 41 is from the reference position A, the stronger the force of the force member 32 becomes. Therefore, regardless of the rotation position of the stopper 28, the stopper 28 is always forced toward the reference position A.

[0114] At the reference position A, if Figure 3B The insertion portion 41 of the stopper 28 is at the same horizontal position as the protrusion 26 of the rotating member 24. By always urging the stopper 28 toward the reference position A, the position where the protrusion 26 and the contact portion 37 start to contact can be constant, and the movement of the stopper 28 can be stabilized.

[0115] Figure 3C The first sensor 34 shown in the figure is a sensor for detecting that the rotating member 24 is located at a predetermined rotational position. The rotating member 24 is provided with a second protrusion 42 which is different from the protrusion (first protrusion) 26. The second protrusion 42 is a portion that protrudes radially outward from the outer peripheral portion of the rotating member 24, similarly to the first protrusion 26.

[0116] The first sensor 34 detects the second protrusion 42 when the second protrusion 42 of the rotating member 24 is located in the detection direction of the first sensor 34. Thus, it is detected that the rotating member 24 is located at a predetermined rotation position. As the first sensor 34, for example, a light detection sensor may be used. Figure 3C In the illustrated state, the second protrusion 42 is not located in the detection direction of the first sensor 34 , so that the first sensor 34 does not detect the second protrusion 42 .

[0117] The first protrusion 26 and the second protrusion 42 are provided at different height positions of the same rotating member 24. The first sensor 34 is arranged at a height position where only the second protrusion 42 is detected but the first protrusion 26 is not detected.

[0118] The positions of the first sensor 34 and the second protrusion 42 are set to the following positions: when the protrusion 26 (first protrusion 26) of the rotating member 24 is located at a position abutting against the abutment portion 37 of the stopper 28, the first sensor 34 detects the second protrusion 42. Therefore, based on the fact that the first sensor 34 detects the second protrusion 42, it can be determined that the rotating member 24 is located at the rotation position abutting against the stopper 28.

[0119] The first sensor 34 detects the rotation position of the rotating member 24. Figure 3B The second sensor 36 shown in FIG. 1 is a sensor for detecting that the stopper 28 is located at a predetermined rotational position.

[0120] The second sensor 36 is similar to the first sensor 34, for example, a light detection sensor. Figure 3B As shown, a detection protrusion 44 is provided on the surface of the stopper 28 on the side opposite to the abutment portion 37. When the detection protrusion 44 is located in the detection direction of the second sensor 36, the second sensor 36 detects the detection protrusion 44. Thus, it is detected that the stopper 28 is located at a predetermined rotational position. Figure 3B In the illustrated state, the second sensor 36 is not located in the detection direction of the detection protrusion 44 , so that the second sensor 36 does not detect the detection protrusion 44 .

[0121] The positions of the second sensor 36 and the detection protrusion 44 are set to the following positions: Figure 6A to Figure 6C ) moves, the second sensor 36 detects the detection protrusion 44. Thus, based on the detection of the detection protrusion 44 by the second sensor 36, it can be determined that the stopper 28 is in a rotation position where it has rotated from the reference position A toward the second stop position B2 due to the contact with the rotating member 24.

[0122] The second sensor 36 is disposed when the stopper 28 is facing the first stop position B1 ( Figure 5A to Figure 5C ) is moved, the position of the detection protrusion 44 will not be detected. According to such a configuration, by combining the detection results of the first sensor 34, in addition to being able to determine that the stopper 28 is in the rotation position abutting against the rotating member 24, it is also possible to determine which of the first stop position B1 and the second stop position B2 the stopper 28 has rotated toward.

[0123] The rotating member 24 having the protrusion 26 described above rotates integrally with the anvil body 20, whereas the movement limiting member 30, the force applying member 32, the first sensor 34, and the second sensor 36, which are structures other than the rotating member 24, are mounted on a frame (not shown) different from the anvil body 20. The different frame is fixed in position so as not to rotate integrally with the anvil body 20 and the rotating member 24. The movement limiting member 30, the force applying member 32, the first sensor 34, and the second sensor 36 also do not rotate integrally with the anvil body 20 and the rotating member 24.

[0124] Next, use Figure 5A to Figure 5C and Figure 6A to Figure 6C The operation of the stopper 28 will be described. Figure 5A to Figure 5C The diagrams are a perspective view, a side view, and a plan view, respectively, showing a state in which the stopper 28 is rotated from the reference position A toward the first stop position B1. Figure 6A to Figure 6C The diagrams are a perspective view, a side view, and a plan view, respectively, showing a state in which the stopper 28 is rotated from the reference position A toward the second stop position B2.

[0125] As described above, the rotation of the anvil body 20 and the rotating member 24 is limited by the control unit 8 in a software manner, and in the normal operation of the component mounting device 1, the rotation range of the rotating member 24 is controlled so that the stopper 28 does not reach any of the stop positions B1 and B2. Assuming that the software-based limitation of the control unit 8 does not function normally, the rotation of the rotating member 24 can also be mechanically limited by the stopper 28 that can only move between the first stop position B1 and the second stop position B2.

[0126] like Figure 5A to Figure 5C As shown, when the rotating member 24 rotates in the first rotation direction P1, the protrusion 26 of the rotating member 24 abuts against the abutment portion 37 of the stopper 28 in the first rotation direction P1. With respect to the rotating member 24 rotating in the first rotation direction P1, the stopper 28 abuts in the second rotation direction P2 which is opposite to the first rotation direction P1. The abutment portion 37 is pressed in the first rotation direction P1, whereby the stopper 28 rotates in the first rotation direction Q1 around the rotation shaft 38.

[0127] As the stopper 28 rotates, the insertion portion 41 of the stopper 28 moves along the hole 40 of the movement limiting member 30. As described above, since the hole 40 has a shape that is closed in the rotation direction of the stopper 28, when the insertion portion 41 reaches one end of the hole 40, it is restricted by the movement limiting member 30 from further rotating in the first rotation direction Q1, and the stopper 28 stops at the first stop position B1.

[0128] like Figure 5A , Figure 5C As shown, even when the stopper 28 moves toward the first stop position B1, the contact state between the contact portion 37 and the protrusion 26 is maintained. It is set so that the contact state is maintained even when the stopper 28 reaches the first stop position B1. Thus, the stopper 28 can function as a stopper that limits the movement of the rotating member 24 in the first rotation direction P1 at the first stop position B1 offset from the reference position A in the first rotation direction P1, Q1.

[0129] like Figure 5C As shown, the second protrusion 42 of the rotating member 24 is located in the detection direction of the first sensor 34. According to the situation that the first sensor 34 detects the second protrusion 42, the control unit 8 ( Figure 1 ) sends a detection signal (ON signal). Based on the detection signal, it is determined that the rotating member 24 is in a rotation position abutting against the stopper 28.

[0130] On the other hand, Figure 5B As shown, the detection protrusion 44 of the stopper 28 is not located in the detection direction of the second sensor 36, and the second sensor 36 does not detect the detection protrusion 44. At this time, the second sensor 36 may send a detection signal (disconnection signal) to the control unit 8.

[0131] As described above, the second sensor 36 detects the detection protrusion 44 only when the stopper 28 moves from the reference position A toward the second stop position B2, and does not detect the detection protrusion 44 when the stopper 28 moves toward the first stop position B1. Thus, even when the first sensor 34 detects the second protrusion 42, when the second sensor 36 does not detect the detection protrusion 44, it can be determined that the stopper 28 has moved toward the first stop position B1 instead of the second stop position B2. It can be determined that the stopper 28 has moved toward the first stop position B1, that is, the rotating member 24 has abutted against the stopper 28 in the first rotation direction P1, causing the stopper 28 to move toward the first stop position B1.

[0132] like Figure 6A to Figure 6C As shown, when the rotating member 24 rotates in the second rotation direction P2, the protruding portion 26 of the rotating member 24 abuts against the abutting portion 37 of the stopper 28 in the second rotation direction P2. With respect to the rotating member 24 rotating in the second rotation direction P2, the stopper 28 abuts in the first rotation direction P1 which is opposite to the second rotation direction P2. The abutting portion 37 is pressed in the second rotation direction P2, whereby the stopper 28 rotates in the second rotation direction Q2 around the rotation axis 38.

[0133] As the stopper 28 rotates, the insertion portion 41 of the stopper 28 moves along the hole 40 of the movement limiting member 30. As described above, since the hole 40 has a shape that is closed in the rotation direction of the stopper 28, the insertion portion 41 is restricted from further rotation in the second rotation direction Q2 by the movement limiting member 30 when reaching the other end of the hole 40, and the stopper 28 stops at the second stop position B2.

[0134] like Fig. 6A , Figure 6C As shown, even when the stopper 28 moves toward the second stop position B2, the contact state between the contact portion 37 and the protrusion 26 is maintained, and it is set to assume that the contact state is maintained even when the stopper 28 reaches the second stop position B2. Thus, the stopper 28 can function as a stopper that limits the movement of the rotating member 24 in the second rotation direction P2 at the second stop position B2 offset from the reference position A in the second rotation direction P2, Q2.

[0135] like Figure 6C As shown, the second protrusion 42 of the rotating member 24 is located in the detection direction of the first sensor 34 , and it is determined that the rotating member 24 is located in the rotation position abutting against the stopper 28 .

[0136] On the other hand, Figure 6B As shown, the detection protrusion 44 of the stopper 28 is also located in the detection direction of the second sensor 36. The second sensor 36 sends a detection signal (ON signal) to the control unit 8 when the detection protrusion 44 is detected.

[0137] As described above, the second sensor 36 does not detect the detection protrusion 44 when the stopper 28 moves toward the first stop position B1, but detects the detection protrusion 44 only when the stopper 28 moves from the reference position A toward the second stop position B2. Thus, by combining the detection result (on signal) of the first sensor 34 and the detection result (on signal) of the second sensor 36, in addition to being able to determine that the rotating member 24 is in a state of abutting against the stopper 28, it is also possible to determine that the stopper 28 has moved toward the second stop position B2. That is, it is possible to determine that the rotating member 24 abuts against the stopper 28 in the second rotation direction P2, causing the stopper 28 to move toward the second stop position B2.

[0138] According to the above-mentioned stopper 28 and its peripheral structure, the rotation range of the rotating member 24 that rotates integrally with the anvil body 20 can be limited by a mechanical method in addition to the software method by the control unit 8. As a result, the cable 22 ( Figure 1 )’s fracture.

[0139] Assuming that the limiter 28 is fixed in position, the movable range of the rotating member 24 is less than 360 degrees. Depending on the orientation of the component 3 inserted into the insertion hole 17 of the substrate 2, sometimes the lead processing portion 18 of the anvil unit 12 cannot perform processing such as bending the lead of the component 3 in the desired direction.

[0140] In contrast, the stopper 28 of the present embodiment is not a fixed type but a movable type, and can only move between the first stop position B1 and the second stop position B2. Figure 4 At the first stop position B1 shown in the figure, the further rotation of the rotating member 24 in the first rotation direction P1 is restricted, and at the second stop position B2 spaced apart from the first stop position B1 in the second rotation direction P2, the further rotation of the rotating member 24 in the second rotation direction P2 is restricted. In this way, the unlimited rotation of the rotating member 24 can be prevented, and the movable range of the rotating member 24 can be set to more than 360 degrees, so that the lead wire of the component 3 can be bent or cut according to various orientations of the component 3.

[0141] In addition, in the above structure, the first sensor 34 and the second sensor 36 are used to determine whether the rotating member 24 is in contact with the stopper 28, and to determine whether the rotating member 24 is rotating forward or reverse when in contact with the stopper 28. Thus, the rotation position of the rotating member 24 can be determined more accurately.

[0142] As described above, the anvil unit 12 of the present embodiment includes the anvil body 20, the second drive mechanism 16, and the stopper 28. The anvil body 20 includes the lead processing portion 18 for processing the lead of the component 3 inserted into the substrate 2. The second drive mechanism 16 has a function of rotating the anvil body 20 in the first rotation direction P1 and a function of reversing the anvil body 20 in the second rotation direction P2. The rotating member 24 rotates together with the anvil body 20 through the second drive mechanism 16, and has a protrusion 26 for limiting rotation. The stopper 28 has a contact portion 37, which contacts the protrusion 26 of the rotating member 24 in the second rotation direction P2 when the rotating member 24 rotates in the first rotation direction P1, and contacts the protrusion 26 of the rotating member 24 in the first rotation direction P1 when the rotating member 24 rotates in the second rotation direction P2. The limiter 28 is configured to be able to move between a first stop position B1 and a second stop position B2, wherein the first stop position B1 limits the movement of the rotating member 24 in the first rotation direction P1, and the second stop position B2 is a position spaced apart from the first stop position B1 in the second rotation direction P2 and limits the movement of the rotating member 24 in the second rotation direction P2.

[0143] According to such a structure, by making the stopper 28 movable, it is possible to prevent the rotating member 24 from rotating without restriction, and the movable range of the rotating member 24 can be set to more than 360 degrees, compared with the case where the stopper 28 is fixed. Thus, when the cable 22 is provided in the anvil body 20, it is possible to prevent the cable 22 from being broken due to excessive rotation of the anvil body 20, and when the component 3 is inserted into the substrate 2 in various orientations, it is possible to perform processing such as bending the lead of the component 3 according to the orientation of the component 3.

[0144] Furthermore, the anvil unit 12 of the present embodiment is further provided with a movement restricting member 30 that restricts the movement of the stopper 28 in a direction deviating from the movement range between the first stop position B1 and the second stop position B2 .

[0145] According to such a configuration, by providing the movement restricting member 30 , the movable range of the rotating member 24 can be set to 360 degrees or more, and the rotating member 24 can be more reliably prevented from rotating without restriction.

[0146] In the anvil unit 12 of the present embodiment, the movement restricting member 30 has a hole 40 into which an insertion portion 41 as a part of the stopper 28 is inserted, and restricts the movement of the stopper 28 by making the hole 40 have a closed shape.

[0147] According to such a configuration, the movement of the stopper 28 can be restricted with a simple structure.

[0148] In addition, in the anvil unit 12 of the present embodiment, the hole 40 is in an arc shape, and the stopper 28 is rotationally moved between the first stop position B1 and the second stop position B2.

[0149] According to such a configuration, when the urging member 32 for urging the stopper 28 toward the reference position A is provided, the stopper 28 can be easily returned to the reference position A, compared with a case where the hole 40 is in a linear shape.

[0150] Furthermore, the anvil unit 12 of the present embodiment further includes an urging member 32 for urging the stopper 28 toward a predetermined reference position A.

[0151] According to such a configuration, by urging the stopper 28 to return to the reference position A, the position where the protrusion 26 of the rotating member 24 and the contact portion 37 of the stopper 28 start to contact each other can be constant, and the operation of the stopper 28 can be stabilized.

[0152] In addition, in the anvil unit 12 of the present embodiment, the reference position A is located between the first stop position B1 and the second stop position B2.

[0153] According to such a configuration, the stopper 28 can be moved in two directions relative to the reference position A, and the operation of the stopper 28 can be stabilized.

[0154] The anvil unit 12 of this embodiment further includes a first sensor 34 and a second sensor 36. The first sensor 34 detects that the rotating member 24 is in contact with the stopper 28, and the second sensor 36 detects that the stopper 28 in contact with the rotating member 24 is in contact with the rotating member 24 at the second stop position B2.

[0155] According to such a configuration, the first sensor 34 detects that the rotating member 24 abuts against the stopper 28, and the second sensor 36 detects that the stopper 28 is located at the second stop position B2 side, thereby determining whether the rotation direction of the rotating member 24 when abutting against the stopper 28 is the first rotation direction or the second rotation direction. Thus, the position of the rotating member 24 can be determined more accurately.

[0156] Furthermore, in the anvil unit 12 of the present embodiment, the lead processing section 18 processes the lead so as to bend the lead.

[0157] According to such a structure, the lead wires of the component 3 can be bent to mount the component 3 on the substrate 2 .

[0158] In addition, the component mounting device 1 of the present embodiment comprises: a substrate positioning portion 6, which positions the substrate 2 at a specified mounting position; a mounting head 10, which 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, which has a lead processing portion 18 for processing the lead of the component 3.

[0159] According to such a structure, the same effect as the above-mentioned anvil unit 12 can be exhibited.

[0160] The above-mentioned embodiment is cited to explain the present invention, but the present invention is not limited to the above-mentioned embodiment. For example, in the embodiment, the case where the force applying member 32 is provided to apply force to the stopper 28 toward the reference position A1 is described, but it is not limited to such a case, and the case where the force applying member 32 is not provided may also be. That is, there may be a case where there is no reference position A to which the stopper 28 is applied. Even in such a case, it is possible to limit further rotation of the rotating member 24 at each stop position B1, B2 by making the stopper 28 only move between the first stop position B1 and the second stop position B2.

[0161] In addition, in the embodiment, as a structure for limiting the movement range of the stopper 28, the case where the hole 40 is provided in the movement limiting member 3 is described, but the present invention is not limited to such a case, and a groove may be provided instead of the hole 40. In other words, the movement limiting member 30 may also have a hole 40 or a groove into which the insertion portion 41 as a part of the stopper 28 is inserted, and the movement of the stopper 28 is limited by making the hole 40 or the groove have a closed shape.

[0162] In addition, in the embodiment, the case where the hole 40 (or groove) is in an arc shape is described, but it is not limited to such a case, and it can also be set to a straight line shape. In such a case, the stopper 28 can also be moved only between the first stop position and the second stop position, and the stopper 28 can also play the function of limiting the rotation of the rotating member 24. When the hole 40 is set to a straight line shape, the structure of the hole 40 and the movement limiting member 30 can be simplified, which also leads to a reduction in the number of parts.

[0163] In addition, in the embodiment, the case where the second sensor 36 detects the state where the stopper 28 abuts against the rotating member 24 on the second stop position B2 side is described, but it is not limited to such a case. The second sensor 36 can also be configured in a manner to detect the state where the stopper 28 abuts against the rotating member 24 on the first stop position B1 side. In such a case, the rotation position and the rotation direction of the rotating member 24 can also be determined in the same manner based on the detection results of the first sensor 34 and the second sensor 36. That is, as the second sensor 36, it is sufficient to detect any one of the state where the stopper 28 abuts against the rotating member 24 on the first stop position B1 side and the state where the stopper 28 abuts against the rotating member 24 on the second stop position B2 side.

[0164] In addition, in the embodiment, the case where the first sensor 34 detects the rotational position of the rotating member 24 and the second sensor 36 detects the rotational position of the limiter 28 is described, but it is not limited to such a case. As the first sensor and the second sensor, any combination of sensors can be used as long as the state of the rotating member 24 abutting against the limiter 28 and the rotation direction at this time can be determined. For example, it is also possible that both the first sensor and the second sensor are sensors that detect the rotational position of the rotating member 24. In this case, it is also possible that the first sensor detects the state of the rotating member 24 abutting against the limiter 28 in the first rotation direction P1, and the second sensor detects the state of the rotating member 24 abutting against the limiter 28 in the second rotation direction P2.

[0165] In addition, in the embodiment, the case where the rotating member 24 abuts against the same abutment portion 37 of the stopper 28 when rotating in the first rotation direction P1 and when rotating in the second rotation direction P2 is described, but the present invention is not limited to such a case. For example, the abutment portion of the stopper 28 may be divided into two different members, and the rotating member 24 abuts against the first abutment portion when rotating in the first rotation direction P1, and abuts against the second abutment portion when rotating in the second rotation direction P2.

[0166] In addition, in the embodiment, the case where the lead processing portion 18 has a cutting blade and cuts the lead of the component 3 is described, but the present invention is not limited to such a case. In the case where the lead of the component 3 is not cut but only has a bending function, any type of processing may be used as long as it is a processing for assembling the component 3 on the substrate 2.

[0167] In addition, in the embodiment, the case where the stopper 28 is provided on the anvil unit 12 is described, but it is not limited to such a case. If the mounting head 10 has a cable (for example, for an axial component), the stopper 28 similar to the present embodiment can also be provided on the mounting head 10. In this case, the anvil body 20 of the anvil unit 12 is replaced with the head body of the mounting head 10, and a rotation drive part (first drive mechanism 14) that rotates the head body, a rotation member that rotates with the head body and has a protrusion, and a stopper that abuts against the protrusion of the rotation member are provided, so that the stopper can move between the first stop position and the second stop position.

[0168] The present invention is fully described with reference to the accompanying drawings and in association with the preferred embodiments, and it is obvious to those skilled in the art that various deformations and modifications are made. Such deformations and modifications should be understood to be included therein as long as they do not depart from the scope of the present invention determined by the attached technical solutions. In addition, the combination of elements in each embodiment and the change of order can be implemented without departing from the scope and concept of the present invention.

[0169] It should be noted that by appropriately combining any of the various modifications of the above-described embodiment, the effects possessed by each modification can be achieved.
