[0004] However, due to problems such as component accuracy, the posture of the component at the pickup position may vary. If the posture of the component at the pickup position varies, there is a high possibility that the component mounting mechanism cannot pick up the component normally and an error occurs. As a result, the supply efficiency of the components decreases.

[0005] It can be said that there is room for improvement in improving the supply efficiency of components, including the component mounting machine of Patent Document 1.

The attitude correction mechanism includes a first restriction unit that restricts lateral movement intersecting the transport direction with respect to the components at the pickup position, and a second restriction unit that restricts forward and backward movement along the transport direction.

[0008] Further, a component mounting machine of the present invention includes the component supply device and a component mounting mechanism that picks up the components at the pickup position of the component supply device and inserts the leads of the picked-up components into a substrate to mount the components on the substrate.

[0009] Further, a component supply method of the present invention includes a transport step of transporting components in a transport direction toward a pickup position, and an attitude correction step of correcting the attitude of the components at the pickup position.

MODE FOR CARRYING OUT THE INVENTION

[0012] Hereinafter, exemplary embodiments of a component supply device, a component mounter including the same, and a component supply method according to the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the specific configurations of the following embodiments, and configurations based on the same technical concept are included in the present invention.

[0013] (Embodiment 1) FIG. 1 shows a component mounter 1 according to Embodiment 1 of the present invention. The component mounter 1 is a device that mounts a component 3 on a substrate 2. The component mounter 1 includes a base 11, a substrate transfer mechanism 12, a plurality of component supply devices 13, a component camera 14, a component mounting mechanism 15, and a control unit 16. Here, for convenience of explanation, the left - right direction of the component mounter 1 as viewed by the operator OP is defined as the X - axis direction, the front - rear direction is defined as the Y - axis direction, and the up - down direction is defined as the Z - axis direction.

[0014] In FIG. 1, the substrate transfer mechanism 12 transfers the substrate 2 along the X - axis direction by a pair of conveyor mechanisms 12a and positions it at a predetermined working position near the central portion of the base 11. The plurality of component supply devices 13 are arranged side by side on a carriage 11D attached to the base 11.

[0015] In FIG. 1, each of the component supply devices 13 is provided with a component supply port 13K on the tip side, and continuously supplies the component 3 to a pickup position 13P (FIG. 2) directly below the component supply port 13K. The component 3 supplied by the component supply device 13 in Embodiment 1 is a radial component with leads (radial taping component), and as shown in FIG. 3, it has a cylindrical body 3B and two leads 3R extending downward from the body 3B.

[0016] In FIG. 1, the component camera 14 is provided in the region between the substrate transfer mechanism 12 and the component supply devices 13. The component camera 14 has its imaging field directed upward and images the component 3 picked up by the component mounting mechanism 15 from below.

[0017] In FIG. 1, the component mounting mechanism 15 includes a head moving mechanism 21 provided on a base 11 and a mounting head 22 moved by the head moving mechanism 21. The head moving mechanism 21 includes a fixed table 21a, a moving table 21b, and a moving plate 21c. The fixed table 21a is fixed to the base 11, and the moving table 21b is provided so as to be movable in the Y-axis direction along the fixed table 21a. The moving plate 21c is provided so as to be movable in the X-axis direction along the moving table 21b, and the mounting head 22 is attached to the moving plate 21c. The mounting head 22 is movable horizontally by the movement of the moving table 21b and the moving plate 21c.

[0018] In FIG. 1, the mounting head 22 includes a plurality of suction nozzles 22a. Each suction nozzle 22a extends downward, the lower end is a component suction port, and it is configured to be movable up and down along the Z-axis direction. The mounting head 22 includes a suction control mechanism 22b, and the suction control mechanism 22b is connected to a vacuum source (not shown). The suction control mechanism 22b generates a vacuum suction force at the component suction port of each suction nozzle 22a by controlling the vacuum pressure supplied from the vacuum source.

[0019] The head moving mechanism 21 moves the mounting head 22 above the component supply port 13K of the component supply device 13, then lowers the suction nozzle 22a, and brings the body 3B of the component 3 into contact with the lower end of the suction nozzle 22a for vacuum suction. Thereby, the component 3 supplied to the pickup position 13P is picked up (FIGS. 2 and 3).

[0020] The control unit 16 is a member for controlling the operation of the component mounter 1. The control unit 16 is electrically connected to each component of the component mounter 1 and controls the operation of each component. The control unit 16 has, for example, a microcomputer. The control unit 16 causes the touch panel 101 to display the content regarding the operation state of the component mounter 1 and accepts the input from the operator OP.

[0021] In FIG. 2, each component supply device 13 has a base portion 31 connected to a carriage 11D (FIG. 1) and a cover portion 32 attached to the base portion 31. A component holding tape 4 is provided in a region covered by the cover portion 32 on the base portion 31. The component holding tape 4 is a tape-shaped member that holds leads 3R of a plurality of components 3, and travels pitchwise in a conveyance direction A along the Y-axis direction in a conveyance path TR provided inside the cover portion 32.

[0022] As shown in FIG. 2, inside the component supply device 13, a first drive source 34 for causing the component holding tape 4 to travel pitchwise is provided. The first drive source 34 of the present embodiment is a cylinder having an output shaft 35, and drives the output shaft 35 back and forth along the conveyance direction A. The first drive source 34 is driven and controlled by a control unit 16.

[0023] The control unit 16 controls the first drive source 34 so as to intermittently perform the feeding operation of the component 3, and intermittently supplies the component 3 to a pickup position 13P.

[0024] The component supply device 13 shown in FIG. 2 is provided with at least two component correction mechanisms 40 and 42 as mechanisms for correcting the posture, position, lead pitch, etc. of the component 3 conveyed in the conveyance path TR. In FIG. 2, the schematic installation locations of the component correction mechanisms 40 and 42 are indicated by dotted lines, and the illustration of the specific configuration is omitted.

[0025] The first component correction mechanism 40 is a mechanism provided on the upstream side A1 in the conveyance direction A from the pickup position 13P, and the second component correction mechanism 42 is a mechanism provided at the pickup position 13P on the downstream side A2 in the conveyance direction A from the first component correction mechanism 40.

[0026] By providing the component correction mechanisms 40 and 42 in the component supply device 13, the posture and position of the component 3 at the pickup position 13P can be stabilized, and the success rate when the component mounting mechanism 15 picks up the component 3 can be improved. Further, when adjusting the lead pitch of the component 3, the leads 3R of the component 3 picked up by the component mounting mechanism 15 can be accurately inserted into the insertion holes of the substrate 2. In this way, the supply efficiency of the component 3 by the component supply device 13 can be improved.

[0027] Hereinafter, the configurations and operations of the component correction mechanisms 40 and 42 will be described with reference to the drawings from FIG. 4 onwards.

[0028] (First Component Correction Mechanism 40: Posture Correction Mechanism 40A) FIGS. 4 and 5 are a perspective view and a plan view of the first component correction mechanism 40 in Embodiment 1. The first component correction mechanism 40 in Embodiment 1 is a posture correction mechanism 40A for correcting the posture of the component 3 in the middle of the transport path TR. Hereinafter, the first component correction mechanism 40 will be described as the posture correction mechanism 40A.

[0029] The posture correction mechanism 40A includes a movable guide 44, a fixed guide 46, a second drive source 48, and a cam mechanism 50. The movable guide 44, the fixed guide 46, the second drive source 48, and the cam mechanism 50 are all attached to the device main body 43 that forms the transport path TR.

[0030] The movable guide 44 and the fixed guide 46 are members for sandwiching the leads 3R of the component 3 therebetween to correct the posture of the component 3 in the transport direction A.

[0031] The movable guide 44 is a guide portion configured to be movable in the lateral direction B, which is a direction intersecting the transport direction A. The lateral direction B in Embodiment 1 is a horizontal direction orthogonal to the transport direction A and corresponds to the X-axis direction. The fixed guide 46 is disposed at a position facing the movable guide 44 with the transport path TR therebetween and is fixed to the device main body 43.

[0032] The area between the movable guide 44 and the fixed guide 46 includes correction positions P1 and P2 for correcting the posture of the component 3. The first correction position P1 is located on the upstream side A1, and the second correction position P2 is located on the downstream side A2. After the component 3 stops at the first correction position P1, it is fed by one pitch and stops at the second correction position P2.

[0033] The movable guide 44 and the fixed guide 46 have the function of changing the inclination of the component 3 at the first correction position P1 toward the front side (downstream side A2), and further have the function of changing the inclination of the component 3 at the second correction position P2 toward the rear side (upstream side A1). By changing the inclination of the component 3 in both the front side and the rear side, even if the component 3 falls forward or backward, it is possible to correct the component 3 toward an upright posture while considering the springback of the lead 3R. Details will be described later.

[0034] The second drive source 48 is a drive source for reciprocating the movable guide 44 in the lateral direction B. The second drive source 48 is provided as a drive source different from the aforementioned first drive source 34 (FIG. 2), and has an output shaft 49 that can be driven along the conveyance direction A. The second drive source 48 of the first embodiment is a cylinder that drives the output shaft 49 back and forth. A cam mechanism 50 is connected to the output shaft 49 of the second drive source 48.

[0035] The cam mechanism 50 is a mechanism for converting the driving force along the conveyance direction A by the second drive source 48 into a driving force in the lateral direction B and transmitting it to the movable guide 44. The cam mechanism 50 includes a cam 54 connected to the output shaft 49 and a cam follower 56 that engages with the cam 54 and is connected to the movable guide 44. A cam groove 55 is formed at the tip of the cam 54, and the protrusion 58 of the cam follower 56 engages with the cam groove 55. The cam groove 55 has an oblique shape in plan view such that when the cam 54 moves back and forth along the conveyance direction A, the cam follower 56 is moved along the lateral direction B. The cam follower 56 is attached to the apparatus main body 43 in a state where it is movable in the lateral direction B while its movement in the front-rear direction is restricted.

[0036] According to such a configuration, when the second drive source 48 drives the output shaft 49 to move back and forth along the conveying direction A, the cam 54 moves back and forth, and the cam follower 56 engaged with the cam 54 reciprocates in the lateral direction B. Thereby, the movable guide 44 connected to the cam follower 56 can be reciprocated in the lateral direction B. In FIGS. 4 and 5, the state (during operation) in which the movable guide 44 is closest to the fixed guide 46 is illustrated.

[0037] Next, the respective configurations of the movable guide 44 and the fixed guide 46 will be described with reference to FIGS. 6 to 9.

[0038] FIGS. 6 and 7 are perspective views showing the movable guide 44, the fixed guide 46, and the component holding tape 4, and FIGS. 8 and 9 are plan views corresponding to FIGS. 6 and 7, respectively. In FIGS. 6 and 8, a state in which the movable guide 44 approaches the fixed guide 46 is shown, and in FIGS. 7 and 9, a state in which the movable guide 44 is separated from the fixed guide 46 is exaggeratedly shown. In FIGS. 6 to 9, illustrations of other components including the component 3 are omitted.

[0039] As shown in FIGS. 7 and 9, the movable guide 44 has two contact portions 60, 62. The contact portions 60, 62 are portions for contacting the leads 3R of the component 3 at the correction positions P1, P2, respectively, to change the posture of the component 3. Both the contact portions 60, 62 have a shape protruding in the lateral direction B toward the fixed guide 46 in the movable guide 44.

[0040] Recesses 64, 66 are formed at both ends of the fixed guide 46. The recesses 64, 66 are recesses for accommodating one ends of the contact portions 60, 62, respectively, when the contact portions 60, 62 approach.

[0041] As shown in FIGS. 7 and 9, the first contact portion 60 has a first inclined portion 60A and a first non-inclined portion 60B, and the second contact portion 62 has a second inclined portion 62A and a second non-inclined portion 62B.

[0042] The inclined portions 60A and 62A are both surfaces that are inclined with respect to both the conveying direction A and the lateral direction B in plan view. The non-inclined portions 60B and 62B are both surfaces that extend in the lateral direction B in plan view.

[0043] The first inclined portion 60A is a portion that contacts the lead 3R of the component 3 at the first correction position P1 and changes the posture of the component 3 toward the front side (downstream side A2). The first inclined portion 60A contacts the lead 3R on the rear side (upstream side A1) of the two leads 3R of the component 3. The first inclined portion 60A of the first embodiment has a tapered shape that is inclined in a direction away from the fixed guide 46 as it goes toward the downstream side A2 of the conveying direction A.

[0044] The second inclined portion 62A is a portion that contacts the lead 3R of the component 3 at the second correction position P2 and changes the posture of the component 3 toward the rear side (upstream side A1). The second inclined portion 62A contacts the lead 3R on the front side (downstream side A2) of the two leads 3R of the component 3. The second inclined portion 62A of the first embodiment has a tapered shape that is inclined in a direction away from the fixed guide 46 as it goes toward the upstream side A1 of the conveying direction A.

[0045] The first non-inclined portion 60B is a portion that extends in the lateral direction B and is connected to the first inclined portion 60A inside the first inclined portion 60A. The first non-inclined portion 60B receives the lead 3R of the component 3 after contacting the first inclined portion 60A and restricts the movement toward the upstream side A1.

[0046] The second non-inclined portion 62B is a portion that extends in the lateral direction B and is connected to the second inclined portion 62A inside the second inclined portion 62A. The second non-inclined portion 62B receives the lead 3R of the component 3 after contacting the second inclined portion 62A and restricts the movement toward the downstream side A2.

[0047] The movable guide 44 further has a connecting portion 68. The connecting portion 68 is a portion that connects the first non-inclined portion 60B and the second non-inclined portion 62B, and extends along the conveying direction A. The connecting portion 68 is located at a position recessed inward with respect to the first non-inclined portion 60B and the second non-inclined portion 62B, and faces the fixed guide 46 in the lateral direction B. The connecting portion 68 and the fixed guide 46 together restrict the lateral movement B of the lead 3R of the component 3 at the correction positions P1 and P2. The connecting portion 68 of the first embodiment has a length including both the first correction position P1 and the second correction position P2.

[0048] A method for correcting the fall of the component 3 in the conveying direction A using the posture correction mechanism 40A having the above-described configuration will be described with reference to FIGS. 10A to 10D and FIGS. 11A to 11D. FIGS. 10A to 10D are diagrams for explaining the correction method when the component 3 is fallen backward, and FIGS. 11A to 11D are diagrams for explaining the correction method when the component 3 is fallen forward.

[0049] In the examples shown in FIGS. 10A and 10B, the component 3 (illustrated by a dotted line) conveyed to the first correction position P1 is in a state of falling backward (upstream side A1) with respect to the upright posture with reference to the vertical axis Q0. The central axis Q1 of the component 3 is inclined backward with respect to the vertical axis Q0. In this state, when the second drive source 48 (FIGS. 4 and 5) is driven to drive the movable guide 44 in the lateral direction B so as to approach the fixed guide 46, the first inclined portion 60A of the first contact portion 60 contacts the rear lead 3R of the component 3 at the first correction position P1 (first contact step). The first inclined portion 60A is inclined so as to be farther away from the fixed guide 46 toward the downstream side A2 in the conveying direction A. As the movable guide 44 moves forward, the first inclined portion 60A biases the lead 3R toward the downstream side A2 while pressing the lead 3R against the fixed guide 46. As a result, the posture of the component 3 is changed to the front side C1 (downstream side A2) (illustrated by a solid line).

[0050] As shown in FIG. 10A, at the first correction position P1, the shape and position of the first inclined portion 60A are set so that the central axis Q2 of the component 3 is inclined forward with respect to the vertical axis Q0. As will be described later, considering that springback occurs in the lead 3R of the component 3, the first inclined portion 60A corrects the posture of the component 3 to a position where it falls forward from the upright posture.

[0051] The lead 3R of the component 3 contacts the first non-inclined portion 60B inside the first inclined portion 60A shown in FIGS. 7 to 9 after contacting the first inclined portion 60A. When springback occurs in the lead 3R of the component 3 and it tries to return to the upstream side A1, the first non-inclined portion 60B receives the lead 3R to restrict the movement to the upstream side A1.

[0052] The lead 3R of the component 3 is arranged in the region between the connection portion 68 provided inside the first non-inclined portion 60B and the fixed guide 46. Thereby, the movement of the lead 3R in the lateral direction B is restricted.

[0053] The state in which the movable guide 44 is retracted from the state shown in FIGS. 10A and 10B is shown in FIGS. 10C and 10D. As shown in FIGS. 10C and 10D, the component 3 at the first correction position P1 was slightly inclined forward with respect to the vertical axis Q0 (shown by a dotted line), the contact with the first contact portion 60 was released, and springback occurred in the lead 3R of the component 3, so that the lead 3R naturally returned to the upstream side A1. The inclination of the component 3 is changed to the rear side C3 (upstream side A1) (shown by a solid line).

[0054] In the first embodiment, considering the springback of the lead 3R, the target posture when correcting the posture of the component 3 by the first inclined portion 60A is set so that the component 3 after springback is generally in an upright posture and the central axis Q3 generally coincides with the vertical axis Q0.

[0055] The component 3 corrected to the upright posture at the first correction position P1 is then sent in the conveying direction A (conveying step) and stops at the second correction position P2. The component 3 stopped at the second correction position P2 is shown in FIGS. 10A and 10B.

[0056] As shown in FIGS. 10A and 10B, the component 3 stopped at the second correction position P2 is generally in an upright posture (illustrated by a dotted line). When the movable guide 44 is driven by the aforementioned second drive source 48 in a direction approaching the fixed guide 46, the second inclined portion 62A of the second contact portion 62 contacts the lead 3R on the front side of the component 3 (second contact step). As a result, the posture of the component 3 is changed to the rear side C2 (upstream side A1) (illustrated by a solid line).

[0057] Regarding the second correction position P2 as well, considering the springback of the lead 3R of the component 3, the target posture of the component 3 after posture correction by the second inclined portion 62A is set to a position where the central axis Q4 of the component 3 is inclined to the rear side C2 with respect to the vertical axis Q0.

[0058] Thereafter, when the movable guide 44 is retracted, as shown in FIGS. 10C and 10D, the component 3 is slightly inclined to the rear side with respect to the vertical axis Q0 (illustrated by a dotted line). Due to springback occurring in the lead 3R of the component 3, the inclination of the component 3 is naturally changed to the front side C4 (downstream side A2) (illustrated by a solid line). Similar to the first correction position P1, after springback, the component 3 is generally in an upright posture, and the central axis Q5 of the component 3 generally coincides with the vertical axis Q0.

[0059] As described above, the component 3 corrected to an upright posture at the first correction position P1 is corrected again toward an upright posture at the second correction position P2. In this way, when the component 3 sent to the first correction position P1 is tilted to the rear side (upstream side A1), the posture of the component 3 is corrected in two stages using the posture correction mechanism 40A to correct the component 3 to an upright posture.

[0060] Next, a posture correction method when the component 3 is tilted to the front side (downstream side B2) will be described with reference to FIGS. 11A to 11D.

[0061] In the example shown in FIGS. 11A and 11B, the component 3 (illustrated by a solid line) that has been conveyed to the first correction position P1 is in a state of being tilted forward (downstream side A2) with respect to the upright posture with reference to the vertical axis Q0. The central axis Q6 of the component 3 is inclined forward with respect to the vertical axis Q0. In this state, when the second drive source 48 (FIGS. 4 and 5) is driven to drive the movable guide 44 in the lateral direction B so as to approach the fixed guide 46, when the component 3 is greatly tilted forward as shown in FIGS. 11A and 11B, the first inclined portion 60A of the first contact portion 60 does not contact the rear lead 3R of the component 3, and the posture of the component 3 is not corrected (arrow C1). In this case, even if the movable guide 44 is retracted, no springback occurs in the lead 3R of the component 3. Therefore, as shown in FIGS. 11C and 11D, the posture of the component 3 is maintained in a state of being tilted forward.

[0062] On the other hand, when the inclination of the component 3 is small, when the movable guide 44 approaches the fixed guide 46, similar to the case shown in FIGS. 10A to 10D, the first inclined portion 60A contacts the rear lead 3R of the component 3, and the posture of the component 3 is corrected forward to C1.

[0063] The component 3 whose posture has not been corrected at the first correction position P1 is then sent to the second correction position P2. As shown in FIGS. 11A and 11B, the component 3 that has stopped at the second correction position P2 is greatly tilted forward (illustrated by a dotted line). When the movable guide 44 is driven in a direction to approach the fixed guide 46 by the aforementioned second drive source 48, the second inclined portion 62A of the second contact portion 62 contacts the front lead 3R of the component 3. As a result, the posture of the component 3 is changed to the rear side C5 (upstream side A1) (illustrated by a solid line).

[0064] Similar to the case shown in FIGS. 10A to 10D, the target posture of the component 3 after posture correction by the second inclined portion 62A is set such that the central axis Q7 of the component 3 is inclined to the rear side C5 with respect to the vertical axis Q0 in consideration of the springback of the lead 3R of the component 3. Thereafter, when the movable guide 44 is retracted, as shown in FIGS. 11C and 11D, springback occurs in the lead 3R of the component 3, and the posture of the component 3 is naturally changed to the front side C6 (downstream side A2) (illustrated by a solid line).

[0065] As described above, even when the component 3 is tilted forward, the posture correction mechanism 40A can be used to correct the component 3 to an upright posture. In this case, when the inclination of the component 3 is large, it is not corrected to the upright posture at the first correction position P1 but is corrected to the upright posture at the second correction position P2. When the inclination of the component 3 is small, it is corrected to the upright posture at both the first correction position P1 and the second correction position P2. In this way, similar to the case where the component 3 is tilted backward, the posture of the component 3 can be corrected toward the upright posture.

[0066] According to the operations shown in FIGS. 10A to 10D and FIGS. 11A to 11D, the posture of the component 3 is changed to the front side at the first correction position P1, and the posture of the component 3 is changed to the rear side at the second correction position P2. Thereby, regardless of whether the component 3 is tilted forward or backward, the component 3 can be corrected toward the upright posture.

[0067] Thereafter, posture correction by the posture correction mechanism 40A is performed on the component 3 that sequentially stops at the correction positions P1 and P2. Thereby, the posture of the component 3 can be uniformly corrected on the way to the pickup position 13P, and the posture of the component 3 that reaches the pickup position 13P can be stabilized. In this way, the success rate when the component mounting mechanism 15 picks up the component 3 at the pickup position 13P can be improved, and the supply efficiency of the component 3 by the component supply device 13 can be improved.

[0068] (Actions and effects related to the posture correction mechanism 40A) As described above, the component supply device 13 of Embodiment 1 includes a transport path TR that transports the component 3 in the transport direction A toward the pickup position 13P, and an attitude correction mechanism 40A that corrects the attitude of the component 3 in the transport path TR. The attitude correction mechanism 40A includes a movable guide 44 that has contact portions 60 and 62 capable of contacting the leads 3R of the component 3 and is movable in the lateral direction B that intersects the transport direction A, and a fixed guide 46 disposed at a position facing the leads 3R of the component 3 with the movable guide 44 interposed therebetween. The movable guide 44 includes a first contact portion 60 that contacts the rear lead (first lead) 3R of the component 3 and a second contact portion 62 that contacts the front lead (second lead) 3R of the component 3. The first contact portion 60 has a first inclined portion 60A inclined so as to tilt the component 3 toward the front side (downstream side A2), and the second contact portion 62 has a second inclined portion 62A inclined so as to tilt the component 3 toward the rear side (upstream side A1).

[0069] According to such a configuration, by enabling the attitude of the component 3 to be changed to the front side and the rear side respectively by the two inclined portions 60A and 62A, the attitude of the component 3 can be corrected even when the attitude of the component 3 is inclined in both the front and rear directions. Thereby, the supply efficiency of the component 3 by the component supply device 13 can be improved.

[0070] Further, according to the component supply device 13 of Embodiment 1, the first inclined portion 60A has a shape inclined in a direction away from the fixed guide 46 toward the downstream side A2 in the transport direction A, and the second inclined portion 62A has a shape inclined in a direction away from the fixed guide 46 toward the upstream side A1 in the transport direction A. According to such a configuration, the attitude of the component 3 can be changed toward a desired target attitude by the two inclined portions 60A and 62A.

[0071] Further, according to the component supply device 13 of Embodiment 1, the first contact portion 60 further has a first non-inclined portion 60B extending along the lateral direction B inside the first inclined portion 60A. Further, the second contact portion 62 further has a second non-inclined portion 62B extending along the lateral direction B inside the second inclined portion 62A. According to such a configuration, the non-inclined portions 60B and 62B can restrict the movement of the lead 3R of the component 3 in the conveyance direction A after contacting the inclined portions 60A and 62A, and the posture of the component 3 can be accurately corrected.

[0072] Further, according to the component supply device 13 of Embodiment 1, the posture correction mechanism 40A has a connection portion 68 extending along the conveyance direction A so as to connect the first non-inclined portion 60B and the second non-inclined portion 62B. According to such a configuration, the lead 3R of the component 3 can be sandwiched between the connection portion 68 and the fixed guide 46 to restrict the movement in the lateral direction B, and the fall of the component 3 in the conveyance direction A can be accurately corrected.

[0073] Further, according to the component supply device 13 of Embodiment 1, the first contact portion 60 is provided on the upstream side A1 in the conveyance direction A of the second contact portion 62. According to such a configuration, the two inclined portions 60A and 62A can be formed inward, and the size of the movable guide 44 can be reduced.

[0074] Further, the component supply device 13 of Embodiment 1 further includes a control unit 16. The control unit 16 controls the first drive source 34 to intermittently perform the feeding operation of the component 3, and stops each component 3 at both a first correction position P1 where the first contact portion 60 contacts the rear lead (first lead) 3R and a second correction position P2 where the second contact portion 62 contacts the front lead (second lead) 3R. According to such a configuration, both the correction for changing the posture of each component 3 to the front side and the correction for changing it to the rear side can be performed, and the posture of the component 3 can be corrected regardless of whether the component 3 tilts forward or backward.

[0075] Further, the component supply device 13 of Embodiment 1 includes a first drive source 34 for performing a feeding operation of the component 3 in the conveyance path TR, and a second drive source 48 for driving the movable guide 44 in the lateral direction B. According to such a configuration, the feeding operation of the component 3 and the reciprocating drive of the movable guide 44 can be executed independently of each other.

[0076] Also, according to the component supply device 13 of Embodiment 1, the feeding operation of the component 3 by the first drive source 34 is performed intermittently, and the driving of the movable guide 44 by the second drive source 48 is performed while the feeding of the component 3 by the first drive source 34 is stopped. According to such a configuration, interference with the component 3 by the movable guide 44 can be prevented.

[0077] Further, the component mounter 1 of Embodiment 1 includes a component supply device 13 having an attitude correction mechanism 40A and a component mounting mechanism 15. The component mounting mechanism 15 picks up the component 3 at the pickup position 13P in the component supply device 13, inserts the leads 3R of the picked-up component 3 into the substrate 2, and mounts the component 3 on the substrate 2. According to the component mounter 1 having such a configuration, the same effects as those of the component supply device 13 having the attitude correction mechanism 40A can be achieved.

[0078] Further, the component supply method of Embodiment 1 includes a conveyance step of conveying the component 3 in the conveyance direction A toward the pickup position 13P, and an attitude correction step of correcting the attitude of the component 3. The attitude correction step executes a first contact step and a second contact step using an attitude correction mechanism 40A including a movable guide 44 and a fixed guide 46. In the first contact step, the first contact portion 60 of the movable guide 44 is brought into contact with the lead 3R (first lead) on the rear side of the component 3, and the component 3 is tilted forward (downstream side A2) by the first inclined portion 60A provided on the first contact portion 60. In the second contact step, the second contact portion 62 of the movable guide 44 is brought into contact with the lead 3R (second lead) on the front side of the component 3, and the component 3 is tilted backward by the second inclined portion 62A provided on the second contact portion 62.

[0079] According to such a method, by enabling the posture of the component 3 to be changed to the front side and the rear side respectively, the posture of the component 3 can be corrected even when the posture of the component 3 tilts forward or backward. Thereby, the supply efficiency of the component 3 can be improved.

[0080] (Modification related to the posture correction mechanism 40A) In the first embodiment, the case of providing one set of the movable guide 44 and the fixed guide 46 has been described, but it is not limited to such a case. For example, two or more sets of the movable guide 44 and the fixed guide 46 may be provided at intervals in the conveyance direction A. In the first embodiment, the case of correcting such that the posture of the component 3 after springback becomes substantially an upright posture at both the first correction position P1 and the second correction position P2 has been described, but it is not limited to such a case. For example, at the first correction position P1, the large fall to the front side is corrected, and at the second correction position P2, the small fall to the rear side is corrected, so that the posture of the component 3 is finally corrected to an upright posture. That is, at the first correction position P1, the posture of the component 3 may be corrected so as not to approach the upright posture. In this case, another set of the movable guide 44 and the fixed guide 46 may be provided on the downstream side B2, and in the other set, at the first correction position, the large fall to the rear side may be corrected, and at the second correction position, the small fall to the front side may be corrected. Thereby, even when the component 3 tilts forward or backward, by providing two sets of the movable guide 44 and the fixed guide 46 and correcting the tilt of the component 3, the posture of the component 3 can be made to approach the upright posture.

[0081] Also, in the first embodiment, the case where one movable guide 44 integrally forms the first contact portion 60 and the second contact portion 62 has been described, but it is not limited to such a case, and they may be configured separately. That is, a first movable guide forming the first contact portion 60 and a second movable guide forming the second contact portion 62 may be provided.

[0082] (The second component correction mechanism 42) Next, the second component correction mechanism 42 provided at the pickup position 13P of the component supply device 13 shown in FIG. 2 will be described with reference to FIGS. 12 to 24B.

[0083] Figs. 12 and 13 are perspective views of the second component correction mechanism 42 in Embodiment 1, and Fig. 14 is a plan view of the second component correction mechanism 42. The second component correction mechanism 42 of Embodiment 1 is an attitude correction mechanism 42A for correcting the attitude of the component 3 at the pick-up position 13P. Hereinafter, the second component correction mechanism 42 will be described as the attitude correction mechanism 42A.

[0084] As described above, the attitude of the component 3 is once corrected on the upstream side A1 of the pick-up position 13P using the attitude correction mechanism 40A. The component supply device 13 of Embodiment 1 further provides an attitude correction mechanism 42A at the pick-up position 13P in order to hold the component 3 at the pick-up position 13P in a more accurate upright posture.

[0085] As will be described later, in the component supply device 13 of Embodiment 1, in order to perform an operation of cutting the lead 3R of the component 3 at the pick-up position 13P, the attitude of the component 3 is likely to collapse at the pick-up position 13P. In response to this, in the component supply device 13 of the present embodiment, an attitude correction mechanism 42A is provided at the pick-up position 13P, and the lead 3R is cut while the attitude of the component 3 is held in an upright posture. Thereby, the attitude of the component 3 can be stabilized even after the cutting operation.

[0086] The attitude correction mechanism 42A shown in Figs. 12 to 14 includes a first regulation unit 100, a second regulation unit 102, a first drive source 34, a cam mechanism 106, and a lead cutting unit 107. The first regulation unit 100, the second regulation unit 102, the first drive source 34, the cam mechanism 106, and the lead cutting unit 107 are all attached to the device main body 43 that forms the conveyance path TR.

[0087] The first regulating unit 100 and the second regulating unit 102 are members for regulating the movement of the component 3 at the pickup position 13P and maintaining the posture of the component 3 in an upright posture. Although the specific configurations of the first regulating unit 100 and the second regulating unit 102 will be described later, the first regulating unit 100 has a function of regulating the movement of the component 3 in the lateral direction B, and the second regulating unit 102 has a function of regulating the movement of the component 3 in the front-rear direction along the conveying direction A of the component 3.

[0088] By providing the first regulating unit 100 and the second regulating unit 102, the movement of the component 3 in the horizontal direction (XY-axis direction) can be regulated, and the component 3 at the pickup position 13P can be accurately held in an upright posture. Thereby, the lead 3R can be cut while maintaining the posture of the component 3.

[0089] In the posture correction mechanism 42A of the first embodiment, the first regulating unit 100 is fixed to the apparatus main body 43, and the second regulating unit 102 is attached to the apparatus main body 43 in a form movable in the lateral direction B. The second regulating unit 102 is driven by a first drive source 34 (FIG. 12) for performing the feeding operation of the component 3.

[0090] The first drive source 34 is a drive source for pitch-feeding the component holding tape 4 shown in FIG. 2, and is also used as a drive source for driving the second regulating unit 102 in the lateral direction B. The output shaft 35 of the first drive source 34 is connected to the cam mechanism 106.

[0091] The cam mechanism 106 is a mechanism for converting the driving force along the conveying direction A of the first driving source 34 into a driving force in the lateral direction B and transmitting it to the second restricting portion 102. The cam mechanism 106 includes a cam 108 connected to the output shaft 35, and a cam follower 110 that engages with the cam 108 and is connected to the second restricting portion 102. A cam groove 109 is formed in the cam 108, and the protrusion 111 of the cam follower 110 engages with the cam groove 109. The cam groove 109 has an oblique shape in plan view such that when the cam 108 moves back and forth along the conveying direction A, the cam follower 110 is moved along the lateral direction B. The cam follower 110 is attached to the apparatus main body portion 43 while being movable in the lateral direction B and restricted from moving in the front-rear direction.

[0092] According to such a configuration, when the first driving source 34 drives the output shaft 35 back and forth along the conveying direction A, the cam 108 moves back and forth, and the cam follower 110 engaged with the cam 108 reciprocates in the lateral direction B. As a result, the second restricting portion 102 connected to the cam follower 110 can be reciprocated in the lateral direction B. The second restricting portion 102 reciprocates between a restricting position for restricting the movement of the component 3 and a retracted position retracted from the component 3. In FIGS. 12 to 14, a state (during operation) in which the second restricting portion 102 is in the restricting position is illustrated.

[0093] The lead cutting portion 107 is a member that cuts the lead 3R of the component 3 at the pickup position 13P. By cutting the lead 3R of the component 3 at the pickup position 13P, the length of the lead 3R is adjusted to a desired length in advance.

[0094] The lead cutting portion 107 has a fixed portion 107A and a movable portion 107B. The fixed portion 107A is a member fixed to the apparatus main body portion 43, and the movable portion 107B is a member configured to be reciprocally movable in the lateral direction B by a driving source (not shown). The fixed portion 107A and the movable portion 107B each have a blade surface (not shown) for cutting the lead 3R of the component 3, and cut the lead 3R by sandwiching the lead 3R of the component 3 between the blade surfaces when the movable portion 107B approaches the fixed portion 107A.

[0095] As shown in FIGS. 12 to 14, a conveying chute 112 is provided on the downstream side A2 of the pickup position 13P. The conveying chute 112 is a member for sending the component holding tape 4 further downstream from the pickup position 13P. Since the component 3 is picked up at the pickup position 13P, the component 3 is not normally held on the component holding tape 4 conveyed to the conveying chute 112. Exceptionally, when the operator OP manually sends the component holding tape 4 downstream to the side A2 with the operation of the component supply device 13 stopped, etc., the component 3 may be held on the component holding tape 4 conveyed to the conveying chute 112.

[0096] Next, the specific configurations of the first restricting portion 100 and the second restricting portion 102 will be described with reference to FIGS. 15 to 17.

[0097] FIG. 15 is a perspective view showing the peripheral configuration of the first restricting portion 100 and the second restricting portion 102, and FIGS. 16 and 17 are side views showing the peripheral configuration.

[0098] As shown in FIG. 15, the first restricting portion 100 includes a first lateral guide 113 and a second lateral guide 114. The lateral guides 113 and 114 are members that restrict the movement of the component 3 at the pickup position 13P by sandwiching it in the lateral direction B. The first lateral guide 113 is provided on the right side in the conveying direction A, and the second lateral guide 114 is provided on the left side in the conveying direction A. Both the lateral guides 113 and 114 are plate-shaped members extending along the conveying direction A, and are fixed at positions on the side of the conveying path TR so as not to interfere with the feeding operation of the component 3.

[0099] The second restricting portion 102 includes a front guide portion 116 and a rear guide portion 118. The guide portions 116 and 118 are members that restrict the movement of the component 3 at the pickup position 13P by sandwiching it in the front-rear direction. The front guide portion 116 is disposed in front of (downstream side A2 of) the pickup position 13P, and the rear guide portion 118 is disposed behind (upstream side A1 of) the pickup position 13P.

[0100] Both the front guide part 116 and the rear guide part 118 are connected to the aforementioned cam follower 110 and move integrally along the lateral direction B. In FIGS. 15 to 17, similar to FIGS. 12 to 14, a state is illustrated in which the front guide part 116 and the rear guide part 118 are in the restricting positions that restrict the movement of the component 3.

[0101] The front guide part 116 of Embodiment 1 has an L-shaped configuration in plan view. The front guide part 116 extends toward the downstream side A2 in the conveying direction A and then bends at a substantially right angle and extends along the lateral direction B. The front end side portion of the front guide part 116 extending along the lateral direction B is arranged so as to block the front of the component 3 and restricts the movement of the component 3 toward the downstream side A2.

[0102] The rear guide part 118 of Embodiment 1 has a so-called "hinge" structure. The rear guide part 118 includes a fixed part 120, a rotating part 122, and a pressing part 124.

[0103] The fixed part 120 is a plate-like member fixed to the cam follower 110. The rotating part 122 is a plate-like member that is connected to the fixed part 120 and is configured to be rotatable about the rotation axis X1. The rotating part 122 has a function of preventing interference with the component 3 by rotating about the rotation axis X1 when contacting the component 3 moving forward along the conveying direction A.

[0104] The pressing part 124 is a biasing member that biases in the reverse rotation direction against the rotational force that causes the rotating part 122 to rotate toward the front side (downstream side A2). By providing the pressing part 124, it is possible to prevent the rotating part 122 from rotating vigorously toward the front side due to contact with the component 3 and stabilize the operation of the rotating part 122.

[0105] Here, the function and operation of the rear guide part 118 will be described with reference to FIGS. 18A and 18B. FIG. 18A is a side view showing a state in which the component 3 is not in contact with the rotating part 122, and FIG. 18B is a side view showing a state in which the component 3 is in contact with the rotating part 122 and the rotating part 122 has rotated.

[0106] As shown in FIG. 18A, the rotating part 122 is in a position extending vertically downward when the component 3 is not in contact. At this time, the tip 110A of the cam follower 110 contacts the base part of the rotating part 122, so that the rotating part 122 is restricted from rotating upstream to A1 (arrow R1). The rotating part 122 can rotate downstream to A2 (arrow R2), but since the pressing part 124 contacts the rotating part 122 and biases it in the opposite direction (arrow R3), resistance is generated when the rotating part 122 rotates.

[0107] As shown in FIG. 18B, when the component 3 is conveyed in the conveying direction A and contacts the rotating part 122, the rotating part 122 rotates downstream to A2 about the rotation axis X1 due to contact with the side surface of the component 3 (arrow R2). By rotating the rotating part 122, interference with the component 3 can be prevented.

[0108] When the rotating part 122 rotates, since the pressing part 124 biases the rotating part 122 in the opposite direction (arrow R3), the rotating part 122 does not rotate vigorously but rotates slowly while maintaining contact with the side surface of the component 3. As a result, the rotating part 122 does not collide with the component 3 (not shown) in front of the component 3 shown in FIG. 18B, rotates only within the necessary range, and the operation of the rotating part 122 becomes stable.

[0109] The operation of the posture correction mechanism 42A having the above-described configuration will be described with reference to the drawings from FIG. 19 onward.

[0110] FIG. 19 is a plan view when the second restricting part 102 is reciprocally driven in the lateral direction B using the first driving source 34 having the output shaft 35. In FIG. 19, (a) corresponds to the state where the second restricting part 102 is in the restricting position, and (b) corresponds to the state where the second restricting part 102 is in the retracted position.

[0111] As shown in Fig. 19(a), when the first drive source 34 drives the output shaft 35 to move the cam 108 of the cam mechanism 106 to the downstream side A2, the protrusion 111 of the cam follower 110 moves in the lateral direction B along the cam groove 109, and the cam follower 110 moves to the left side of the paper surface. The second restricting portion 102 connected to the cam follower 110 also moves toward the left side of the paper surface and moves to a restricting position for restricting the movement of the component 3 at the pickup position 13P.

[0112] As shown in Fig. 19(b), when the first drive source 34 drives the output shaft 35 to move the cam 108 of the cam mechanism 106 to the upstream side A1, the protrusion 111 of the cam follower 110 moves in the lateral direction B along the cam groove 109, and the cam follower 110 moves toward the right side of the paper surface. The second restricting portion 102 connected to the cam follower 110 also moves toward the right side of the paper surface and moves to a retracted position retracted from the component 3 at the pickup position 13P.

[0113] By driving the output shaft 35 in the front-rear direction by the first drive source 34 at a predetermined cycle, the state shown in (a) and the state shown in (b) are alternately switched. The second restricting portion 102 reciprocates between the restricting position and the retracted position to selectively restrict the movement of the component 3 in the front-rear direction.

[0114] In particular, in the first embodiment, the common first drive source 34 is used to perform the pitch feed of the component 3 and the drive of the second restricting portion 102. For this reason, the rotating portion 122 is provided in the rear guide portion 118, and by preventing the interference between the feeding operation of the component 3 and the rear guide portion 118, it becomes possible to execute the pitch feed of the component 3 and the drive of the second restricting portion 102 in parallel.

[0115] Here, the configuration related to the feeding operation of the component 3 will be described with reference to Fig. 20. Fig. 20 is a schematic side view showing the component holding tape 4 and a plurality of components 3 held by the component holding tape 4.

[0116] As shown in Fig. 20, the component holding tape 4 has a plurality of feed holes 126 for pitch feed. A claw portion (not shown) connected to the first drive source 34 engages with the feed hole 126.

[0117] When the first drive source 34 drives the claw portion toward the downstream side A2, the claw portion is engaged with the feed hole 126, and the component holding tape 4 is advanced by one pitch. On the other hand, when the first drive source 34 drives the claw portion toward the upstream side A1, the engagement state between the claw portion and the feed hole 126 is released, so the component holding tape 4 remains stationary without retreating. By reciprocating the claw portion by the first drive source 34 at a predetermined cycle, the component holding tape 4 is pitch-fed along the conveyance direction A, and the feeding operation of the component 3 is intermittently performed.

[0118] In particular, in the first embodiment, large radial components are handled as the component 3. As shown in FIG. 20, the pitch Y2 of the component 3 is set longer than the pitch Y1 of the feed hole 126 (doubled in the first embodiment). When the first drive source 34 performs driving for two reciprocations, the component holding tape 4 is sent to the downstream side A2 by two pitches (Y1×2) of the feed hole 126, and the component 3 is sent to the downstream side A2 by one pitch (Y2).

[0119] When the first drive source 34 is driven for two reciprocations and the component 3 is fed by one pitch, the reciprocating motion of the second regulating portion 102 by the same first drive source 34 reciprocates two times in the lateral direction B. That is, when the component 3 is fed by 0.5 pitch, the second regulating portion 102 reciprocates once in the lateral direction B, so that the rear guide portion 118 of the second regulating portion 102 contacts the component 3 in front of the pickup position 13P.

[0120] In response to this, the posture correction mechanism 42A of the first embodiment is provided with the rotating portion 122 described above on the rear guide portion 118 so that it can rotate when the rotating portion 122 contacts the side surface of the component 3 in front of the pickup position 13P. Thereby, when performing the feeding operation of the component 3 and the reciprocating operation of the second regulating portion 102 using the same first drive source 34, both operations can be executed in parallel while preventing interference between the component 3 and the second regulating portion 102.

[0121] The specific operation of the posture correction mechanism 42A having the above-described configuration will be described with reference to FIGS. 21A to 24B.

[0122] Figures 21A and 21B are a side view and a perspective view showing the state after the component 3 at the pickup position 13P has been picked up.

[0123] As shown in Figures 21A and 21B, the first restricting portion 100 has already restricted the movement of the component 3 in the lateral direction B from the component 3 located at a position behind the pickup position 13P. On the other hand, the second restricting portion 102 is in the retracted position and does not restrict the movement of the component 3.

[0124] When the first drive source 34 drives the output shaft 35 forward (downstream side A2) from the state shown in Figures 21A and 21B, the state shown in Figures 22A and 22B is obtained.

[0125] As shown in Figures 22A and 22B, the component 3 is sent 0.5 pitch downstream (conveying step), and the second restricting portion 102 is moved in the lateral direction B so as to approach the conveying path TR.

[0126] Since the component 3 is in front of the pickup position 13P, when the rotating portion 122 of the second restricting portion 102 moves in the lateral direction B, it contacts the side surface of the component 3. Due to the contact with the component 3, the rotating portion 122 rotates toward the downstream side A2 (arrow R2 in Figure 22A). Thereby, interference between the rear guide portion 118 and the component 3 is prevented. At this time, since the rotating portion 122 rotates while being biased to the opposite side by the pressing portion 124, it does not rotate vigorously toward the downstream side A2, but rotates gently while maintaining the contact state with the side surface of the component 3. Thereby, the rotation operation of the rotating portion 122 can be stabilized.

[0127] In this way, even when the component 3 advances by 0.5 pitch by one reciprocation drive of the first drive source 34, the feeding operation of the component 3 and the reciprocating operation of the second restricting portion 102 can be executed in parallel while preventing interference between the rear guide portion 118 and the component 3.

[0128] When the first drive source 34 drives the output shaft 35 backward (upstream side A1) from the state shown in Figures 22A and 22B, the state shown in Figures 23A and 23B is obtained.

[0129] As shown in FIGS. 23A and 23B, the component 3 is in a stationary state without moving, and the second restricting portion 102 moves in the lateral direction B so as to move away from the conveyance path TR and moves to the retracted position. The rotating portion 122 whose contact with the component 3 has been released returns to a state of extending vertically downward.

[0130] When the first drive source 34 drives the output shaft 35 to the front side (downstream side A2) from the state shown in FIGS. 23A and 23B, the state shown in FIGS. 24A and 24B is obtained.

[0131] As shown in FIGS. 24A and 24B, the component 3 is sent to the downstream side A2 by 0.5 pitch and reaches the pickup position 13P. The second restricting portion 102 moves in the lateral direction B so as to approach the conveyance path TR. Since the component 3 is moving to the pickup position 13P, the rotating portion 122 does not contact the component 3. The rotating portion 122 enters the region between the component 3 at the pickup position 13P and the component 3 in front of it.

[0132] As described with reference to FIG. 18A, the rotation of the rotating portion 122 to the upstream side A1 is restricted by the tip 110A of the cam follower 110, and the movement of the component 3 to the upstream side A1 is restricted. Thereby, the component 3 at the pickup position 13P is sandwiched between the front guide portion 116 and the rear guide portion 118 in the front-rear direction, and the movement in the front-rear direction is restricted.

[0133] In the state shown in FIGS. 24A and 24B, the first restricting portion 100 restricts the movement in the lateral direction B with respect to the component 3 at the pickup position 13P (first restricting step), and the second restricting portion 102 restricts the movement in the front-rear direction along the conveyance direction A (second restricting step). Thereby, the movement of the component 3 in the horizontal direction is restricted, and the component 3 can be accurately held in the upright posture.

[0134] Thereafter, the lead 3R of the component 3 at the pickup position 13P is cut by the lead cutting portion 107. Specifically, the movable portion 107B approaches the fixed portion 107A and sandwiches the lead 3R of the component 3 therebetween, so that the lead 3R is cut.

[0135] The cutting operation of the lead 3R by the lead cutting portion 107 is performed in a state where the first regulating portion 100 and the second regulating portion 102 regulate the horizontal movement of the component 3. Thereby, it is possible to suppress the posture of the component 3 from being disrupted by the cutting operation of the lead 3R, and the upright posture of the component 3 can be accurately maintained.

[0136] The component 3 with the lead 3R cut is picked up by the component mounting mechanism 15 shown in FIG. 1. The component mounting mechanism 15 lowers the mounting head 22 positioned above the pickup position 13P, brings the suction nozzle 22a of the mounting head 22 into contact with the upper surface of the body 3B of the component 3, and sucks the component 3. Thereby, the component 3 at the pickup position 13P is picked up, and the supply of the component 3 by the component supply device 13 is performed.

[0137] The component mounting mechanism 15 that has picked up the component 3 then inserts the lead 3R of the component 3 into the insertion hole of the substrate 2 and mounts it on the substrate 2.

[0138] (Function and Effect of the Posture Correction Mechanism 42A) As described above, the component supply device 13 of the first embodiment includes a transport path TR that transports the component 3 in the transport direction A toward the pickup position 13P, a first drive source 34 for performing a feeding operation of the component 3 on the transport path TR, and a posture correction mechanism 42A that corrects the posture of the component 3 at the pickup position 13P. The posture correction mechanism 42A includes a first regulating portion 100 that regulates the movement of the component 3 at the pickup position 13P in the lateral direction B that intersects the transport direction A, and a second regulating portion 102 that regulates the movement of the component 3 in the front-rear direction along the transport direction A.

[0139] According to such a configuration, by correcting the posture of the component 3 at the pickup position 13P using the posture correction mechanism 42A, the pickup success rate of the component 3 can be improved. Thereby, the supply efficiency of the component 3 by the component supply device 13 can be improved.

[0140] Moreover, according to the component supply device 13 of Embodiment 1, the second regulation unit 102 includes a front guide unit 116 located on the downstream side A2 of the pickup position 13P and a rear guide unit 118 located on the upstream side A1 of the pickup position 13P. According to such a configuration, by providing the guide units 116 and 118 before and after the component 3 at the pickup position 13P, the movement in the front-rear direction can be accurately regulated.

[0141] Moreover, according to the component supply device 13 of Embodiment 1, the second regulation unit 102 is configured to be movable along the lateral direction B, and reciprocates between a regulation position for regulating the movement of the component 3 at the pickup position 13P and a retracted position. According to such a configuration, by making the second regulation unit 102 movable, the movement regulation operation of the component 3 by the second regulation unit 102 can be executed in parallel with the feeding operation of the component 3.

[0142] Moreover, according to the component supply device 13 of Embodiment 1, the rear guide unit 118 has a rotating unit 122 configured to be rotatable in response to contact with the side surface of the component 3 when moving in a direction approaching the component 3 in front of the pickup position 13P. According to such a configuration, even when contacting the component 3 in front of the pickup position 13P, the rotating unit 122 of the rear guide unit 118 rotates, preventing interference with the component 3.

[0143] Moreover, according to the component supply device 13 of Embodiment 1, the second regulation unit 102 is connected to the first drive source 34 and is driven in the lateral direction B along with the feeding operation of the component 3 by the first drive source 34. According to such a configuration, the feeding operation of the component 3 and the movement operation of the second regulation unit 102 can be performed using the common first drive source 34.

[0144] Moreover, according to the component supply device 13 of Embodiment 1, the posture correction mechanism 42A further has a cam mechanism 106 that converts the driving force in the front-rear direction by the first drive source 34 into a driving force in the lateral direction B and transmits it to the second regulation unit 102. According to such a configuration, the driving force of the first drive source 34 can be transmitted to the second regulation unit 102 while being converted using a simple mechanism.

[0145] Also, according to the component supply device 13 of Embodiment 1, the component 3 is a radial taping component, and the conveyance path TR conveys a component holding tape 4 holding a plurality of components 3 in the conveyance direction A. According to such a configuration, in the case of radial components, especially when the component accuracy is poor, the inclination in the conveyance direction A is likely to vary. However, by restricting the movement in the front-rear direction with the second restricting portion 102, the effect of correcting the posture can be greatly achieved.

[0146] Also, according to the component supply device 13 of Embodiment 1, the first restricting portion 100 includes a first lateral guide 113 located on one side in the lateral direction B with respect to the component 3 at the pickup position 13P, and a second lateral guide 114 located on the other side. According to such a configuration, the movement of the component 3 in the lateral direction B can be restricted with a simple mechanism.

[0147] Also, the component mounting machine 1 of Embodiment 1 further includes a lead cutting portion 107 that cuts the lead 3R of the component 3 at the pickup position 13P. According to such a configuration, even when cutting the lead 3R of the component 3 at the pickup position 13P, the cutting operation can be executed in a state where the movement of the component 3 in the horizontal direction is restricted by the first restricting portion 100 and the second restricting portion 102. Therefore, the posture of the component 3 can be accurately maintained even after the lead is cut.

[0148] Also, the component mounting machine 1 of Embodiment 1 includes a component supply device 13 having a posture correction mechanism 42A and a component mounting mechanism 15. The component mounting mechanism 15 picks up the component 3 at the pickup position 13P in the component supply device 13, inserts the lead 3R of the picked-up component 3 into the substrate 2, and mounts the component 3 on the substrate 2. According to the component mounting machine 1 having such a configuration, the same effect as that of the component supply device 13 having the posture correction mechanism 42A can be achieved.

[0149] In addition, the component supply method of Embodiment 1 includes a conveying step of conveying the component 3 in the conveying direction A toward the pickup position 13P, and an attitude correction step of correcting the attitude of the component 3 at the pickup position 13P. In the attitude correction step, a first restriction step of restricting the movement in the lateral direction B intersecting the conveying direction A with respect to the component 3 at the pickup position 13P, and a second restriction step of restricting the movement in the front-rear direction along the conveying direction A are executed.

[0150] According to such a method, by correcting the attitude of the component 3 at the pickup position 13P, the pickup success rate of the component 3 can be improved, and the supply efficiency of the component 3 can be improved.

[0151] (Modification related to the attitude correction mechanism 42A) In Embodiment 1, as shown in FIG. 20, the case where twice the pitch Y1 of the feed holes 126 of the component holding tape 4 corresponds to the pitch Y2 of the component 3, and when the first drive source 34 performs two reciprocating drives, the component 3 is fed by one pitch has been described. However, it is not limited to such a case. When the first drive source 34 performs one reciprocating drive or three or more reciprocating drives to feed the component 3 by one pitch, the relationship between the pitch Y1 of the feed holes 126 and the pitch Y2 of the component 3 may be appropriately changed. Even in such a case, according to the attitude correction mechanism 42A of Embodiment 1, when the first drive source 34 performs one reciprocating drive, the second restriction unit 102 also moves one reciprocatingly. Therefore, movement restriction can be performed on the component 3 reaching the pickup position 13P every time. In addition, since the rotating unit 122 is provided in the rear guide unit 118, interference with the component 3 in front of the pickup position 13P can also be prevented.

[0152] (Embodiment 2) The component supply device of Embodiment 2 according to the present invention will be described. In Embodiment 2, mainly the differences from Embodiment 1 will be described, and the descriptions overlapping with Embodiment 1 will be omitted.

[0153] In Embodiment 1, as the first component correction mechanism 40, a posture correction mechanism 40A (Figs. 4 to 11D) for correcting the posture of the component 3 was provided. However, in Embodiment 2, as the first component correction mechanism 40, a lead pitch adjustment mechanism 40B for adjusting the pitch of the two leads 3R of the component 3 is provided. Hereinafter, the first component correction mechanism 40 will be described as the lead pitch adjustment mechanism 40B.

[0154] Figs. 25 and 26 are respectively a perspective view and a plan view of the lead pitch adjustment mechanism 40B in Embodiment 2.

[0155] The lead pitch adjustment mechanism 40B includes a movable guide 200, a fixed guide 202, a stopper 204, a second drive source 206, and a cam mechanism 208. The movable guide 200, the fixed guide 202, the stopper 204, the second drive source 206, and the cam mechanism 208 are all attached to the apparatus main body portion 43 that forms the conveyance path TR.

[0156] The movable guide 200 is a guide portion configured to be movable in the lateral direction B. The movable guide 200 has a function of changing the pitch of the leads 3R by contacting the two leads 3R of the component 3 stopped at a predetermined pitch adjustment position P3 in the conveyance path TR. In FIGS. 25 and subsequent figures, the case where the body 3B of the component 3 is in a rectangular parallelepiped shape is illustrated as an example.

[0157] The fixed guide 202 is a guide portion disposed at a position facing the movable guide 200 with the conveyance path TR interposed therebetween, and is fixed to the apparatus main body portion 43. The fixed guide 202 is provided at a position facing the body 3B and the leads 3R of the component 3 at the pitch adjustment position P3, and has functions such as holding the posture of the component 3 when the movable guide 200 contacts the leads 3R of the component 3.

[0158] The stopper 204, together with the fixed guide 202, is a member for holding the posture of the component 3 at the pitch adjustment position P3. The stopper 204 is disposed at a position facing the fixed guide 202 across the transport path TR and is fixed to the apparatus main body 43. When the body 3B of the component 3 is disposed between the stopper 204 and the fixed guide 202, the movement of the body 3B in the lateral direction B is restricted.

[0159] The movable guide 200 and the stopper 204 are provided on the same side of the transport path TR and at different height positions. The movable guide 200 is disposed at the same height position as the lead 3R of the component 3, and the stopper 204 is disposed at the same height position as the body 3B of the component 3. The fixed guide 202 is disposed at a height position overlapping both the lead 3R and the body 3B of the component 3.

[0160] The second drive source 206 is a drive source for reciprocating the movable guide 200 in the lateral direction B. The second drive source 206 is provided as a drive source different from the aforementioned first drive source 34 (FIG. 2) and has an output shaft 207 that can be driven along the transport direction A. The second drive source 206 of the second embodiment is a cylinder that drives the output shaft 207 back and forth. A cam mechanism 208 is connected to the output shaft 207 of the second drive source 206.

[0161] The cam mechanism 208 is a mechanism for converting the driving force of the second drive source 206 along the transport direction A into a driving force in the lateral direction B and transmitting it to the movable guide 200. The cam mechanism 208 includes a cam 210 connected to the output shaft 207 and a cam follower 212 engaged with the cam 210 and connected to the movable guide 200. A cam groove 211 is formed at the tip of the cam 210, and the protrusion 213 of the cam follower 212 is engaged with the cam groove 211. The cam groove 211 has an oblique shape in plan view such that when the cam 210 moves back and forth along the transport direction A, the cam follower 212 is moved along the lateral direction B. The cam follower 212 is attached to the apparatus main body 43 in a state where it can move in the lateral direction B while the movement in the front-rear direction is restricted.

[0162] According to such a configuration, when the second drive source 206 drives the output shaft 207 back and forth along the conveyance direction A, the cam 210 moves back and forth, and the cam follower 212 engaged with the cam 210 reciprocates in the lateral direction B. Thereby, the movable part 200 connected to the cam follower 212 can be reciprocated in the lateral direction B. FIGS. 25 and 26 illustrate a state where the movable guide 200 is closest to the fixed guide 202.

[0163] Next, the configurations of the movable guide 200, the fixed guide 202, and the stopper 204 will be described with reference to FIGS. 27 to 34.

[0164] 27 and 28 are a plan view and a perspective view showing the movable guide 200, the fixed guide 202, the stopper 204, and the component holding tape 4, respectively. FIGS. 29 and 30 are a plan view and a perspective view showing the movable guide 200 and the component holding tape 4, respectively.

[0165] As shown in FIGS. 27 to 30, the movable guide 200 has two contact portions 214 and 216. The contact portions 214 and 216 each have a function of contacting the lead 3R (illustrated by a dotted line in FIG. 27) of the component 3 at the pitch adjustment position P3 to adjust the pitch of the lead 3R. The contact portions 214 and 216 of the second embodiment have a function of narrowing the pitch of the two leads 3R of the component 3.

[0166] As shown in FIGS. 29 and 30, the contact portions 214 and 216 each have a shape protruding in the lateral direction B toward the fixed guide 202 in the movable guide 200. The first contact portion 214 has a first inclined portion 214A and a first non-inclined portion 214B, and the second contact portion 216 has a second inclined portion 216A and a second non-inclined portion 216B.

[0167] Both the inclined portions 214A and 216A are surfaces inclined with respect to both the conveyance direction A and the lateral direction B in plan view. The inclined portions 214A and 216A are inclined in opposite directions to each other in plan view. On the other hand, the non-inclined portions 214B and 216B are surfaces extending in the lateral direction B in plan view.

[0168] The first inclined portion 214A contacts the rear lead 3R (upstream side A1) among the two leads 3R of the component 3 at the pitch adjustment position P3. The first inclined portion 214A in Embodiment 1 has a tapered shape that inclines in a direction away from the fixed guide 202 as it goes toward the downstream side A2 in the conveyance direction A.

[0169] The second inclined portion 216A contacts the front lead 3R (downstream side A2) among the two leads 3R of the component 3 at the pitch adjustment position P3. The second inclined portion 216A in Embodiment 1 has a tapered shape that inclines in a direction away from the fixed guide 202 as it goes toward the upstream side A1 in the conveyance direction A.

[0170] The first non-inclined portion 214B is a portion that extends in the lateral direction B and is connected to the first inclined portion 214A inside the first inclined portion 214A. The first non-inclined portion 214B receives the lead 3R of the component 3 after contacting the first inclined portion 214A and restricts the movement toward the upstream side A1.

[0171] The second non-inclined portion 216B is a portion that extends in the lateral direction B and is connected to the second inclined portion 216A inside the second inclined portion 216A. The second non-inclined portion 216B receives the lead 3R of the component 3 after contacting the second inclined portion 216A and restricts the movement toward the downstream side A2.

[0172] By providing the non-inclined portions 214B and 216B, it is possible to restrict the pitch of the leads 3R narrowed by the inclined portions 214A and 216A from widening.

[0173] The distance D1 between the first non-inclined portion 214B and the second non-inclined portion 216B shown in FIGS. 29 and 30 is set based on the desired pitch length of the leads 3R. In Embodiment 1, considering the springback of the leads 3R, the distance D1 between the non-inclined portions 214B and 216B is set shorter than the desired pitch length of the leads 3R.

[0174] The movable guide 200 further has a connecting portion 218. The connecting portion 218 is a portion connecting the first non-inclined portion 214B and the second non-inclined portion 216B, and extends along the conveying direction A. The connecting portion 218 is provided at a position recessed inward with respect to the first non-inclined portion 214B and the second non-inclined portion 216B.

[0175] The position (depth) of the connecting portion 218 is set such that when the movable guide 200 contacts the lead 3R of the component 3, the lead 3R and the connecting portion 218 face each other in the lateral direction B without contacting each other. The lead 3R of the component 3 only contacts the inclined portions 214A, 216A and the non-inclined portions 214B, 216B.

[0176] Figs. 31 to 35 are perspective views showing the peripheral configurations of the movable guide 200 and the fixed guide 202.

[0177] Fig. 31 is a view showing the movable guide 200 and the fixed guide 202 separately, and Fig. 32 is a view showing a state where the movable guide 200 approaches the fixed guide 202. Fig. 33 is a view showing the stopper 204 separately, Fig. 34 is a view showing the fixed guide 202, the stopper 204, and the component 3 held by the component holding tape 4, and Fig. 35 is a view obtained by adding the movable guide 200 to the configuration shown in Fig. 34.

[0178] As shown in Fig. 31, the fixed guide 202 has a facing surface 220 and two recesses 224, 226.

[0179] The facing surface 220 is a surface facing the facing surface 225 of the stopper 204 shown in Fig. 33. By sandwiching the body 3B of the component 3 between the facing surface 220 and the facing surface 225, as shown in Figs. 34 and 35, the movement of the component 3 in the lateral direction B at the pitch adjustment position P3 is restricted.

[0180] The recesses 224 and 226 are recesses for receiving the contact portions 214 and 216 of the movable guide 200, respectively. As shown in FIG. 32, when the movable guide 200 approaches the fixed guide 202, the recesses 224 and 226 accommodate one ends of the contact portions 214 and 216, respectively, thereby preventing interference between the movable guide 200 and the fixed guide 202.

[0181] As shown in FIG. 33, the stopper 204 has a facing surface 225. The facing surface 225, together with the facing surface 220 of the fixed guide 202 described above, has a function of sandwiching the body 3B of the component 3 and is provided at the same height position as the body 3B of the component 3.

[0182] A method for adjusting the pitch of the lead 3R of the component 3 using the lead pitch adjustment mechanism 40B having the above-described configuration will be described with reference to FIGS. 36A to 36D. FIGS. 36A to 36D are plan views for explaining a method for adjusting the pitch of the lead 3R using the lead pitch adjustment mechanism 40B.

[0183] As shown in FIG. 36A, a component holding tape 4 (not shown) is sent in the conveying direction A (conveying step), and a new component 3 stops at the pitch adjustment position P3. With the stop of the component 3, the movable guide 200 is driven in the lateral direction B (arrow F1), and the contact portions 214 and 216 advance toward the two leads 3R of the component 3 at the pitch adjustment position P3. In the example shown in FIG. 36A, the pitch of the two leads 3R is the length D2.

[0184] When the movable guide 200 advances, as shown in FIG. 36B, the first contact portion 214 contacts the rear lead 3R of the component 3, and the second contact portion 216 contacts the front lead 3R of the component 3 (first contact step). In the first contact portion 214, the portion where contact with the lead 3R of the component 3 starts is the first inclined portion 214A, and in the second contact portion 216, the portion where contact with the lead 3R of the component 3 starts is the second inclined portion 216A.

[0185] Both the inclined portions 214A and 216A have a tapered shape that inclines inwardly as they approach the connecting portion 218. Therefore, as the movable guide 200 advances (arrow F2), the two leads 3R are pressed in a direction approaching each other (arrow F3). As a result, the pitch of the leads 3R is gradually narrowed.

[0186] When the movable guide 200 further advances, as shown in FIG. 36C, the two leads 3R come into contact with the non-inclined portions 214B and 216B beyond the inclined portions 214A and 216A (second contact step). Since the non-inclined portions 214B and 216B have a shape in which the interval in the conveying direction A is kept constant, a pressing force is applied to the two leads 3R in a direction in which the pitch is narrowed even while the movable guide 200 advances (arrow F4). At this time, the pitch of the leads 3R is temporarily narrowed to the interval D1 between the non-inclined portions 214B and 216B described above.

[0187] The component 3 is also pressed in the lateral direction B by contact with the inclined portions 214A and 216A. However, as shown in FIGS. 36B and 36C, the body 3B of the component 3 abuts against the fixed guide 202. Since the stopper 204 is also provided on the opposite side of the fixed guide 202, the pitch adjustment of the leads 3R is performed while the movement of the component 3 at the pitch adjustment position P3 in the lateral direction B is restricted.

[0188] When the movable guide 200 is retracted in the lateral direction B from the state shown in FIG. 36C (arrow F5), as shown in FIG. 36D, the movable guide 200 moves to the retracted position, and the contact between the contact portions 214 and 216 and the leads 3R of the component 3 is released.

[0189] Since the leads 3R of the component 3 are made of an elastic material, springback occurs in the leads 3R as the contact with the contact portions 214 and 216 is released. As a result, the pitch of the leads 3R widens to a length D3 (>D1, <D2). Considering such springback, the interval D1 between the non-inclined portions 214B and 216B is set shorter than the desired length D3, and the pitch of the leads 3R after springback can be changed to the desired length D3.

[0190] Thereafter, the component holding tape 4 is fed in the conveying direction A, and the next component 3 stops at the pitch adjustment position P3. By reciprocating the movable guide 200 also with respect to the next component 3, the pitch of the leads 3R can be adjusted to a desired length. In this way, the pitch of the leads 3R can be adjusted for each of the components 3 conveyed along the conveying path TR.

[0191] Each component 3 is conveyed toward the pickup position 13P with the leads 3R having a desired pitch. As a result, when the component mounting mechanism 15 picks up the component 3 and inserts the leads 3R of the component 3 into the insertion holes of the substrate 2, it can be inserted accurately, and the occurrence of errors due to the pitch of the leads 3R can be reduced. In this way, the supply efficiency of the components 3 by the component supply device 13 can be improved.

[0192] (Operations and effects related to the lead pitch adjustment mechanism 40B) As described above, the component supply device 13 of Embodiment 1 includes a conveying path TR that conveys the component 3 in the conveying direction A toward the pickup position 13P, and a lead pitch adjustment mechanism 40B that adjusts the pitch of the leads 3R of the component 3 in the conveying path TR. The lead pitch adjustment mechanism 40B includes a movable guide 200 that is movable in the lateral direction B intersecting the conveying direction A, and a fixed guide 202 provided at a position facing the component 3 with the component 3 sandwiched between the movable guide 200. The movable guide 200 has contact portions 214, 216 that can contact the two leads 3R of the component 3 when moving in a direction approaching the component 3. The contact portions 214, 216 have inclined portions 214A, 216A that are inclined in a direction to narrow the pitch of the two leads 3R.

[0193] According to such a configuration, in the conveying path TR in which the two leads 3R are conveyed at intervals in the conveying direction A, by bringing the contact portions 214, 216 of the movable guide 200 into contact with the leads 3R, the pitch of the leads 3R can be adjusted. Thereby, the pitch of the leads 3R can be adjusted in the conveying path TR, and the supply efficiency of the components 3 by the component supply device 13 can be improved.

[0194] Further, according to the component supply device 13 of Embodiment 1, the contact portions 214 and 216 further have non-inclined portions 214B and 216B that extend along the lateral direction B inside the inclined portions 214A and 216A. According to such a configuration, after the leads 3R of the component 3 come into contact with the inclined portions 214A and 216A, they come into contact with the non-inclined portions 214B and 216B, thereby restricting the movement of the leads 3R in the conveying direction A and making it easier to adjust the pitch of the leads 3R to a constant length.

[0195] Further, according to the component supply device 13 of Embodiment 1, the contact portions 214 and 216 further have connection portions 218 (opposing portions) inside the non-inclined portions 214B and 216B. The connection portions 218 face the leads 3R of the component 3 in contact with the non-inclined portions 214B and 216B with a space therebetween in the lateral direction B. According to such a configuration, by preventing the leads 3R of the component 3 from coming into contact with the connection portions 218, it is possible to suppress damage to the leads 3R due to contact with the connection portions 218 while maintaining the contact state between the leads 3R and the non-inclined portions 214B and 216B.

[0196] Further, according to the component supply device 13 of Embodiment 1, the fixed guide 202 forms recesses 224 and 226 that accommodate one ends of the contact portions 214 and 216 when the movable guide 200 approaches the fixed guide 202. According to such a configuration, the movable guide 200 can be moved to a position closer to the fixed guide 202. For example, it is possible to design to make the non-inclined portions 214B and 216B longer and increase the time and distance during which the leads 3R come into contact with the non-inclined portions 214B and 216B.

[0197] Further, according to the component supply device 13 of Embodiment 1, the lead pitch adjustment mechanism 40B further includes a stopper 204 that faces and sandwiches the body 3B of the component 3 with respect to the fixed guide 202 and is arranged at a different height position with respect to the movable guide 200. According to such a configuration, by sandwiching the body 3B of the component 3 in the lateral direction B between the fixed guide 202 and the stopper 204, the posture of the component 3 when the movable guide 200 contacts the lead 3R to adjust the pitch can be stabilized. Thereby, the adjustment accuracy of the pitch can be improved.

[0198] Further, according to the component supply device 13 of Embodiment 1, it includes a first drive source 34 for performing the feeding operation of the component 3 in the transport path TR and a second drive source 206 for driving the movable guide 200 in the lateral direction B. According to such a configuration, the feeding operation of the component 3 and the movement of the movable guide 200 can be executed independently.

[0199] Further, the component supply device 13 of Embodiment 1 further includes a control unit 16. The control unit 16 intermittently performs the feeding operation of the component 3 by the first drive source 34 and drives the movable guide 200 by the second drive source 206 while the feeding of the component 3 is stopped. According to such a configuration, the feeding operation of the component 3 and the pitch adjustment of the lead 3R can be performed respectively while preventing interference between the movable guide 200 and the component 3.

[0200] Further, the component mounter 1 of Embodiment 1 includes a component supply device 13 having a lead pitch adjustment mechanism 40B and a component mounting mechanism 15. The component mounting mechanism 15 picks up the component 3 at the pickup position 13P in the component supply device 13, inserts the lead 3R of the picked-up component 3 into the substrate 2, and mounts the component 3 on the substrate 2. According to the component mounter 1 having such a configuration, the same effects as those of the component supply device 13 having the lead pitch adjustment mechanism 40B can be achieved.

[0201] Further, the component supply method of Embodiment 1 includes a conveying step of conveying the component 3 in the conveying direction A toward the pickup position 13P, and a lead pitch request step of adjusting the pitch of the leads 3R of the component 3. The lead pitch adjustment step uses a lead pitch adjustment mechanism 40B including a movable guide 200 movable in the lateral direction B intersecting the conveying direction A, and a fixed guide 202 provided at a position facing the component 3 with the component 3 interposed therebetween with respect to the movable guide 200. The movable guide 200 is moved in a direction approaching the component 3, and a first contact step is executed in which the inclined portions 214A, 216A provided on the movable guide 200 are brought into contact with the leads 3R of the component 3 to widen the pitch of the leads 3R.

[0202] According to such a method, the pitch of the leads 3R can be adjusted in the conveying path TR, and the supply efficiency of the component 3 can be improved.

[0203] (Modification related to the lead pitch adjustment mechanism 40B) In Embodiment 2, the case where the lead pitch adjustment mechanism 40B narrows the pitch of the leads 3R of the component 3 has been described. However, it is not limited to such a case, and the adjustment may be made to widen the pitch of the leads 3R. In this case, by changing the inclination directions of the inclined portions 214A, 216A of the contact portions 214, 216, the shape can be changed to widen the pitch of the leads 3R. Thus, the inclined portions 214A, 216A of the contact portions 214, 216 only need to be inclined in a direction to widen or narrow the pitch of the two leads 3R.

[0204] (Embodiment 3) The component supply device of Embodiment 3 according to the present invention will be described. In Embodiment 3, mainly the points different from Embodiments 1 and 2 will be described, and the descriptions overlapping with Embodiments 1 and 2 will be omitted.

[0205] In Embodiment 2, as the first component correction mechanism 40, a lead pitch adjustment mechanism 40B for adjusting the pitch of the two leads 3R of the component 3 was provided. However, in Embodiment 3, as the first component correction mechanism 40, a "component correction mechanism 40C" having a function of adjusting the pitch of the lead 3R and a function of correcting the posture of the component 3 is provided. Hereinafter, the first component correction mechanism 40 will be described as the component correction mechanism 40C.

[0206] FIG. 37 and FIG. 38 are a perspective view and a plan view, respectively, of the component correction mechanism 40C according to Embodiment 3.

[0207] The component correction mechanism 40C includes a pusher 300, a lever member 302, a pedestal 304, a second drive source 306, and a cam mechanism 308. The pusher 300, the lever member 302, the pedestal 304, the second drive source 306, and the cam mechanism 308 are all attached to the apparatus main body portion 43 that forms the conveyance path TR.

[0208] The pusher 300 is a member for pressing and rotating the lever member 302. The pusher 300 is configured to be movable in the lateral direction B, and moves (in the pressing direction G1) so as to approach the component 3 stopped at a predetermined correction position P4, passes through the gap between the two leads 3R of the component 3, and presses the lever member 302.

[0209] The lever member 302 is a member that rotates by the pressing of the pusher 300. The lever member 302 is disposed at a position facing the pusher 300 with the conveyance path TR interposed therebetween. When the lever member 302 rotates, the restricting portions 336 and 340 (FIG. 40) of the lever member 302 face the two leads 3R of the component 3 at the correction position P4 in the conveyance direction A. By sandwiching the two leads 3R in the gap between the pusher 300 and the lever member 302, the functions of positioning the leads 3R at predetermined positions and correcting the pitch of the leads 3R and the function of correcting the posture of the component 3 are realized.

[0210] The pedestal 304 is a member that rotatably supports the lever member 302. The pedestal 304 is fixed to the apparatus main body portion 43.

[0211] The second drive source 306 is a drive source for reciprocating the pusher 300 in the lateral direction B. The second drive source 306 is provided as a drive source different from the aforementioned first drive source 34 (FIG. 2), and has an output shaft 307 that can be driven along the conveyance direction A. The second drive source 306 of Embodiment 3 is a cylinder that drives the output shaft 307 back and forth. A cam mechanism 308 is connected to the output shaft 307 of the second drive source 306.

[0212] The cam mechanism 308 is a mechanism for converting the driving force of the second drive source 306 along the conveyance direction A into a driving force in the lateral direction B and transmitting it to the pusher 300. The cam mechanism 308 includes a cam 310 connected to the output shaft 307 and a cam follower 312 that engages with the cam 310 and is connected to the pusher 300. A cam groove 311 is formed at the tip of the cam 310, and a protrusion 313 of the cam follower 312 engages with the cam groove 311. The cam groove 311 has an oblique shape in plan view such that when the cam 310 moves back and forth along the conveyance direction A, the cam follower 312 is moved along the lateral direction B. The cam follower 312 is attached to the apparatus main body 43 in a state where it is movable in the lateral direction B while its movement in the front-rear direction is restricted.

[0213] According to such a configuration, when the second drive source 306 drives the output shaft 307 back and forth along the conveyance direction A, the cam 310 moves back and forth, and the cam follower 312 engaged with the cam 310 reciprocates in the lateral direction B. As a result, the pusher 300 connected to the cam follower 312 can be reciprocated in the lateral direction B. FIGS. 37 and 38 illustrate a state (when not in operation) in which the pusher 300 is separated from the lever member 302.

[0214] Next, the peripheral configuration of the pusher 300 and the lever member 302 will be described with reference to FIGS. 39 to 42. In FIGS. 39 to 42, the illustration of the component 3 is omitted.

[0215] FIG. 39 is an enlarged perspective view of the peripheral configuration of the pusher 300 and the lever member 302.

[0216] As shown in FIG. 39, the pusher 300 has a pressing surface 314 for pressing the lever member 302. The pressing surface 314 is one end portion of the pusher 300 that protrudes in the lateral direction B, and faces the lever member 302 in the lateral direction B. The pressing surface 314 is a surface that extends along the conveying direction A in a plan view.

[0217] The lever member 302 has a first lever 316 and a second lever 318.

[0218] The first lever 316 and the second lever 318 are each configured to be rotatable and perform a rotational operation by the pressing of the pressing surface 314 of the pusher 300. In Embodiment 3, the first lever 316 and the second lever 318 are pressed in the pressing direction G1 by the pressing surface 314 of the same pusher 300.

[0219] The first lever 316 is rotatable in the rotational direction R4 about a first rotation axis 317 extending in the Z-axis direction, and the second lever 318 is rotatable in the rotational direction R5 about a second rotation axis 319 extending in the Z-axis direction. When the first lever 316 performs a rotational operation, it faces the lead 3R on the rear side (upstream side A1) among the two leads 3R of the component 3. When the second lever 318 performs a rotational operation, it faces the lead 3R on the front side (downstream side A2) among the two leads 3R of the component 3.

[0220] The component correction mechanism 40C further includes a biasing member 320, a first stopper 322, and a second stopper 324.

[0221] The biasing member 320 is a member for biasing the first lever 316 and the second lever 318. The biasing member 320 in Embodiment 3 is a spring-like member that connects between the first lever 316 and the second lever 318 and biases them in a direction to pull the first lever 316 and the second lever 318.

[0222] The first lever 316 is biased by a biasing member 320 in a rotational direction R6 opposite to the rotational direction toward the lead 3R on the rear side of the component 3. The second lever 318 is biased by the biasing member 320 in a rotational direction R7 opposite to the rotational direction toward the lead 3R on the front side of the component 3. By providing the biasing member 320, the first lever 316 and the second lever 318 in a state where they are not pressed by the pusher 300 (when not operating) can be retracted.

[0223] The first stopper 322 is a member that restricts further rotation of the first lever 316 biased by the biasing member 320. The second stopper 324 is a member that restricts further rotation of the second lever 318 biased by the biasing member 320. By providing the first stopper 322 and the second stopper 324, the first lever 316 and the second lever 318 are respectively stopped at predetermined retracted positions.

[0224] In addition to the function of restricting the rotation of the levers 316, 318, the first stopper 322 and the second stopper 324 further have a function of supporting the prevention of the lead 3R of the component 3 from falling off when the levers 316, 318 rotate due to the pressing of the pusher 300. Details will be described later.

[0225] Next, the detailed configurations of the pusher 300, the lever member 302, the biasing member 320, and the stoppers 322, 324 will be described with reference to FIGS. 40 to 42. FIGS. 40 to 42 are perspective views of the pusher 300, the lever member 302, the biasing member 320, and the stoppers 322, 324.

[0226] As shown in FIGS. 40 to 42, the pusher 300 has, in addition to the pressing surface 314, a first inclined surface 326, a second inclined surface 328, a first opposing surface 330, a second opposing surface 331, a third opposing surface 332, and a fourth opposing surface 333.

[0227] The first inclined surface 326 and the second inclined surface 328 are each a surface inclined with respect to the conveyance direction A and the lateral direction B in a plan view. The first inclined surface 326 is located at a position facing the lateral direction B with respect to the first lever 316, and the second inclined surface 328 is located at a position facing the lateral direction B with respect to the second lever 318.

[0228] The first inclined surface 326 and the second inclined surface 328 are inclined in different directions from each other. The first inclined surface 326 is inclined in a direction away from the lever member 302 as it goes toward the upstream side A1 of the conveyance direction A, and the second inclined surface 328 is inclined in a direction away from the lever member 302 as it goes toward the downstream side A2 of the conveyance direction A.

[0229] The first opposing surface 330 and the second opposing surface 331 are each a surface disposed inside the first inclined surface 326 and the second inclined surface 328, and extend along the lateral direction B in a plan view. The first opposing surface 330 and the second opposing surface 331 are each a surface that faces the lead 3R of the component 3 from the side opposite to the levers 316 and 318 when the levers 316 and 318 perform a rotational operation. The first opposing surface 330 faces the rear lead 3R of the component 3 together with the first lever 316, and the second opposing surface 331 faces the front lead 3R of the component 3 together with the second lever 318.

[0230] By providing the opposing surfaces 330 and 331, the leads 3R of the component 3 can be sandwiched in the conveyance direction A together with the lever member 302 and positioned at a predetermined position. Thereby, the pitch of the two leads 3R can be adjusted, and the posture of the component 3 in the conveyance direction A can be corrected.

[0231] The third opposing surface 332 and the fourth opposing surface 333 are each a surface disposed inside the first opposing surface 330 and the second opposing surface 331, and extend along the conveyance direction A in a plan view. The third opposing surface 332 and the fourth opposing surface 333 are each a surface that faces the lead 3R of the component 3 in the lateral direction B when the pusher 300 advances in the pressing direction G1. The third opposing surface 332 faces the rear lead 3R of the component 3, and the fourth opposing surface 333 faces the front lead 3R of the component 3.

[0232] As shown in FIGS. 40 to 42, the first lever 316 has a first pressed portion 334 and a first restricting portion 336.

[0233] The first pressed portion 334 is one end portion pressed by the pressing surface 314 of the pusher 300, and faces the lateral direction B with respect to the pressing surface 314. The first restricting portion 336 is an end portion at a position different from that of the first pressed portion 334, and faces the lead 3R on the rear side of the component 3 when the first lever 316 rotates.

[0234] As shown in FIGS. 40 to 42, the second lever 318 has a second pressed portion 338 and a second restricting portion 340.

[0235] The second pressed portion 338 is one end portion pressed by the pressing surface 314 of the pusher 300, and faces the lateral direction B with respect to the pressing surface 314. The second restricting portion 340 is an end portion at a position different from that of the second pressed portion 338, and contacts the lead 3R on the front side of the component 3 when the second lever 318 rotates.

[0236] As shown in FIG. 40, the first stopper 322 has a first lever abutting portion 342 and a first lead facing portion 344.

[0237] The first lever abutting portion 342 is a portion that abuts against the first lever 316 biased by the biasing member 320 to prevent further rotation in the rotation direction R6. The first lead facing portion 344 is a portion that faces the third facing surface 332 of the pusher 300 with the lead 3R on the rear side of the component 3 interposed therebetween when the pusher 300 advances in the pressing direction G1.

[0238] As shown in FIG. 40, the second stopper 324 has a second lever abutting portion 346 and a second lead facing portion 348.

[0239] The second lever abutting portion 346 is a portion that abuts against the second lever 318 biased by the biasing member 320 to prevent further rotation in the rotational direction R7. The second lead facing portion 348 is a portion that faces the fourth facing surface 333 of the pusher 300 across the lead 3R on the front side of the component 3 when the pusher 300 advances in the pressing direction G1.

[0240] A method of correcting the posture of the component 3 by adjusting the pitch of the lead 3R of the component 3 using the component correction mechanism 40C having the above-described configuration will be described with reference to FIGS. 43A and 43B. FIGS. 43A and 43B are schematic plan views for explaining a method of correcting the component 3 using the component correction mechanism 40C.

[0241] As shown in FIG. 43A, in a state where the pusher 300 is in the retracted position (non-operating state), the component holding tape 4 is pitch-fed in the conveying direction A (conveying step), and one component 3 (illustrated by a dotted line) stops at the correction position P4. Along with the stop of the component 3, the second drive source 306 (FIGS. 37 and 38) drives the pusher 300 to advance in the pressing direction G1.

[0242] When the pusher 300 advances in the pressing direction G1, the pressing surface 314 of the pusher 300 passes between the two leads 3R and moves toward the pressed portions 334 and 338 of the levers 316 and 318.

[0243] As shown in FIG. 43B, the pressing surface 314 of the pusher 300 contacts the pressed portions 334 and 338 of the levers 316 and 318 and presses in the pressing direction G1. Each of the levers 316 and 318 rotates, the first lever 316 rotates in the rotational direction R8 about the first rotation axis 317, and the second lever 318 rotates in the rotational direction R9 about the second rotation axis 319 (component correction step).

[0244] As the first lever 316 rotates, the first regulating portion 336 faces the lead 3R on the rear side (upstream side A1) of the component 3 in the first pressing direction H1. The first pressing direction H1 is a direction toward the downstream side A2 in the conveying direction A. In the example shown in FIG. 43B, the first regulating portion 336 contacts the lead 3R of the component 3 and presses it in the first pressing direction H1. The lead 3R of the component 3 pressed in the first pressing direction H1 is pressed toward the first opposing surface 330 of the advanced pusher 300. As a result, the rear lead 3R is positioned in the gap between the first regulating portion 336 and the first opposing surface 330, and the movement in the front-rear direction along the conveying direction A is restricted (first lead correction step).

[0245] The lead 3R is further sandwiched between the third opposing surface 332 of the advanced pusher 300 and the first lead opposing portion 344 of the first pusher 322. As a result, the movement of the rear lead 3R in the lateral direction B is also restricted. In this way, the movement of the lead 3R in the horizontal direction is restricted.

[0246] The first regulating portion 336 of the first lever 316 that rotates in the rotation direction R8 abuts against the first lead opposing portion 344 of the first stopper 322, and further rotation is restricted. The first lead opposing portion 344 also functions as a stopper for the first lever 316.

[0247] As the second lever 318 rotates, the second regulating portion 340 faces the lead 3R on the front side (downstream side A2) of the component 3 in the second pressing direction H2. The second pressing direction H2 is a direction toward the upstream side A1 in the conveying direction A. In the example shown in FIG. 43B, the second regulating portion 340 contacts the lead 3R of the component 3 and presses it in the second pressing direction H2. The lead 3R of the component 3 pressed in the second pressing direction H2 is pressed toward the second opposing surface 331 of the advanced pusher 300. As a result, the front lead 3R is positioned in the gap between the second regulating portion 340 and the second opposing surface 331, and the movement in the front-rear direction along the conveying direction A is restricted (second lead correction step).

[0248] The lead 3R is further sandwiched between the fourth opposing surface 333 of the advanced pusher 300 and the second lead opposing portion 348 of the second pusher 324. As a result, the forward lead 3R is also restricted from moving in the lateral direction B. In this way, the horizontal movement of the lead 3R is restricted.

[0249] In addition, the second restricting portion 340 of the second lever 318 that rotates in the rotation direction R9 abuts against the second lead opposing portion 348 of the second stopper 324, and further rotation is restricted. The second lead opposing portion 348 also functions as a stopper for the second lever 318.

[0250] In the state shown in FIG. 43B, by positioning the two leads 3R at their respective predetermined positions, the pitch of the leads 3R is adjusted to a desired length, and the posture of the component 3 is corrected. In the state before adjustment shown in FIG. 43A, when the pitch of the two leads 3R is wider than the desired pitch length, as shown in FIG. 43B, the restricting portions 336 and 340 press the two leads 3R in a direction approaching each other, thereby narrowing the pitch of the leads 3R. At the same time, when the two leads 3R are inclined with respect to the vertical direction (Z-axis direction), the component 3 is corrected toward an upright posture.

[0251] Thereafter, when the pusher 300 is driven in the retracting direction G2 opposite to the pressing direction G1, it returns to the same state as shown in FIG. 43A. Although springback occurs in the lead 3R, the pitch of the lead 3R approaches the desired pitch length and the posture of the component 3 approaches an upright posture compared to the state before operating the pusher 300.

[0252] Thereafter, the component holding tape 4 is fed in the conveying direction A, and the next component 3 is stopped at the correcting position P4. By reciprocating the pusher 300 with respect to the next component 3 as well, the pitch of the lead 3R can be adjusted to a desired length, and the toppling of the component 3 can be corrected. In this way, the pitch adjustment of the lead 3R and the correction of the toppling of the component 3 can be performed for each of the components 3 conveyed along the conveying path TR.

[0253] Each component 3 is conveyed toward the pickup position 13P with the leads 3R having a desired pitch. Thereby, when the component mounting mechanism 15 picks up the component 3 and inserts the leads 3R of the component 3 into the insertion holes of the substrate 2, it can be inserted accurately, and the occurrence of errors due to the pitch of the leads 3R can be reduced. Further, since each component 3 is conveyed toward the pickup position 13P while being maintained in a substantially upright posture, the pickup success rate of the component 3 by the component mounter 15 is improved. In this way, the supply efficiency of the component 3 by the component supply device 13 can be improved.

[0254] In addition, in the examples shown in FIGS. 43A and 43B, the case where the pitch of the two leads 3R before the pusher 300 operates is wide and the pitch of the leads 3R is narrowed has been described. However, it is not limited to such a case, and it is also possible to adjust so as to widen the pitch of the leads 3R. For example, in the state before adjustment shown in FIG. 43A, when the pitch of the two leads 3R is narrow, as the pusher 300 advances, the two leads 3R come into contact with the inclined surfaces 326 and 328. The rear lead 3R contacts the first inclined surface 326, and the front lead 3R contacts the second inclined surface 328. Depending on the inclination directions of the inclined surfaces 326 and 328, the rear lead 3R is guided outward (upstream side A1) toward the first opposing surface 330, and the front lead 3R is guided outward (downstream side A2) toward the second opposing surface 331. Thereby, the pitch of the two leads 3R is widened, and the leads 3R are positioned at a predetermined position as in the case shown in FIG. 43B. In this way, even when the pitch of the leads 3R is narrow, by using the inclined surfaces 326 and 328, the pitch of the leads 3R can be widened and the posture of the component 3 can be corrected.

[0255] (Actions and effects related to the component correction mechanism 40C) As described above, the component supply device 13 of Embodiment 3 includes a conveyance path TR that conveys the component 3 in the conveyance direction A toward the pickup position 13P, and a component correction mechanism 40C for correcting the component 3 in the conveyance path TR. The component correction mechanism 40C includes a pusher 300 that is movable in the lateral direction B intersecting the conveyance direction A so as to pass between the leads 3R, and a lever member 302 that rotates by being pressed by the pusher 300. The lever member 302 includes a first lever 316 and a second lever 318. The first lever 316 rotates about a first rotation axis 317 in response to the pressing of the pressing surface 314 (first pressing surface) of the pusher 300, and sandwiches the lead 3R (first lead) of the component 3 between the first opposing surface 330 of the pusher 300. The second lever 318 rotates about a second rotation axis 319 in response to the pressing of the pressing surface 314 (second pressing surface) of the pusher 300, and sandwiches the lead 3R (second lead) of the component 3 between the second opposing surface 331 of the pusher 300.

[0256] According to such a configuration, by sandwiching the two leads 3R with the pusher 300 and the two levers 316 and 318, it is possible to adjust the pitch of the two leads 3R or correct the tilt of the component 3. Thereby, the supply efficiency of the component 3 by the component supply device 13 can be improved.

[0257] Further, according to the component supply device 13 of Embodiment 3, the first lever 316 has a first restricting portion 336 that restricts the movement in the conveyance direction A by sandwiching the lead 3R (first lead) between the first opposing surface 330 of the pusher 300, and the second lever 318 has a second restricting portion 340 that restricts the movement in the conveyance direction A by sandwiching the lead 3R (second lead) between the second opposing surface 331 of the pusher 300. According to such a configuration, by restricting the movement of the two leads 3R in the conveyance direction A, it is possible to accurately perform the pitch adjustment of the leads 3R and the tilt correction of the component 3.

[0258] Further, according to the component supply device 13 of Embodiment 3, the pusher 300 further has a third opposing surface 332 that opposes the lead 3R (first lead) sandwiched between the first opposing surface 330 and the first lever 316 in the lateral direction B, and a fourth opposing surface 333 that opposes the lead 3R (second lead) sandwiched between the second opposing surface 331 and the second lever 318 in the lateral direction B. According to such a configuration, the dropout of the lead 3R in the lateral direction B can be prevented by the opposing surfaces 332 and 333.

[0259] Further, according to the component supply device 13 of Embodiment 3, the pusher 300 further has a first inclined surface 326 that extends obliquely between the pressing surface 314 (first pressing surface) and the first opposing surface 330, and a second inclined surface 328 that extends obliquely between the pressing surface 314 (second pressing surface) and the second opposing surface 331. According to such a configuration, when the pitch of the lead 3R is particularly narrow, the lead 3R of the component 3 can be brought into contact with the inclined surfaces 326 and 328 and guided toward the opposing surfaces 330 and 331.

[0260] Further, according to the component supply device 13 of Embodiment 3, the first lever 316 is disposed upstream of the second lever 318 in the conveying direction A, the first inclined surface 326 has a shape that inclines away from the first lever 316 toward the upstream side A1 in the conveying direction A, and the second inclined surface 328 has a shape that inclines away from the second lever 318 toward the downstream side A2 in the conveying direction A. According to such a configuration, miniaturization of the tip of the pusher 300 can be achieved.

[0261] Further, according to the component supply device 13 of Embodiment 3, the pressing surface 314 (first pressing surface) that presses the first lever 316 and the pressing surface 314 (second pressing surface) that presses the second lever 318 are formed on the same surface of the pusher 300. According to such a configuration, the configuration of the pusher 300 can be simplified.

[0262] Further, according to the component supply device 13 of Embodiment 3, the component correction mechanism 40C further includes a biasing member 320 that biases the first lever 316 in the rotational direction R6 away from the lead 3R (first lead) on the rear side of the component 3 and biases the second lever 318 in the rotational direction R7 away from the lead 3R (second lead) on the front side of the component 3. According to such a configuration, it can be retracted when the lever member 302 is not pressed by the pusher 300.

[0263] Further, according to the component supply device 13 of Embodiment 3, the component correction mechanism 40C further includes a first stopper 322 that abuts against the first lever 316 biased by the biasing member 320 (first biasing member) to restrict further rotation of the first lever 316, and a second stopper 324 that abuts against the second lever 318 biased by the biasing member (second biasing member) to restrict further movement of the second lever 318. According to such a configuration, the levers 316 and 318 biased by the biasing member 320 can be made to standby at a predetermined retracted position away from the conveyance path TR.

[0264] Further, according to the component supply device 13 of Embodiment 3, the first stopper 322 is disposed at a position facing the lead 3R (first lead) sandwiched between the first opposing surface 330 of the pusher 300 and the first lever 316 in the lateral direction B, and the second stopper 324 is disposed at a position facing the lead 3R (second lead) sandwiched between the second opposing surface 331 of the pusher 300 and the second lever 318 in the lateral direction B. According to such a configuration, the stoppers 322 and 324 can prevent the lead 3R from dropping off in the lateral direction B.

[0265] Further, according to the component supply device 13 of Embodiment 3, the first lever 316 and the second lever 318 are biased by a common biasing member 320. According to such a configuration, the number of components of the component correction mechanism 40C can be reduced, and cost reduction can be achieved.

[0266] Further, the component mounter 1 of Embodiment 3 includes a component supply device 13 having a component correction mechanism 40C and a component mounting mechanism 15. The component mounting mechanism 15 picks up the component 3 at the pickup position 13P in the component supply device 13, inserts the leads 3R of the picked-up component 3 into the substrate 2, and mounts the component 3 on the substrate 2. According to the component mounter 1 having such a configuration, the same effects as those of the component supply device 13 having the component correction mechanism 40C can be achieved.

[0267] Further, the component supply method of Embodiment 3 includes a conveying step of conveying the component 3 in the conveying direction A toward the pickup position 13P and a component correction step of correcting the component 3. The component correction step executes a first lead correction step and a second lead correction step using the component correction mechanism 40C. In the first lead correction step, the first lever 316 of the lever member 302 is pressed and rotated by the pressing surface 314 (first pressing surface) of the pusher 300, and the lead 3R (first lead) of the component 3 is sandwiched between the first opposing surface 330 of the pusher 300 and the first lever 316. In the second lead correction step, the second lever 318 of the lever member 302 is pressed and rotated by the pressing surface 314 (second pressing surface) of the pusher 300, and the second lead correction step of sandwiching the lead 3R (second lead) of the component 3 between the second opposing surface 331 of the pusher 300 and the second lever 318 is executed.

[0268] According to such a component supply method, by sandwiching the two leads 3R with the pusher 300 and the two levers 316 and 318, the pitch of the leads 3R can be adjusted or the inclination of the component 3 can be corrected. Thereby, the supply efficiency of the component 3 can be improved.

[0269] (Modification related to the component correction mechanism 40C) In Embodiment 3, the case where one pusher 300 presses the two levers 316 and 318 has been described. However, the present invention is not limited to such a case, and the two levers may be pressed by separate pushers, respectively. This modification will be described with reference to FIGS. 44 to 45B.

[0270] FIG. 44 is a perspective view showing a component correction mechanism 40D according to a modification of Embodiment 3. FIGS. 45A and 45B are schematic plan views for explaining a method of correcting a component 3 using the component correction mechanism 40D according to this modification.

[0271] The component correction mechanism 40D shown in FIG. 44 includes two pushers 400A and 400B, and two levers 416 and 418.

[0272] The first pusher 400A is a member for pressing and rotating the first lever 416, and the second pusher 400B is a member for pressing and rotating the second lever 418. The first pusher 400A, together with the first lever 416, positions a lead 3R (not shown) on the rear side of the component 3 at the first correction position P5. The second pusher 400B, together with the second lever 418, positions a lead 3R (not shown) on the rear side of the component 3 at the second correction position P6.

[0273] In this modification, the two pushers 400A and 400B are integrally formed and are driven in the lateral direction B by the same drive source (for example, the second drive source 306 of Embodiment 3).

[0274] The first pusher 400A has a first pressing surface 414A, a first inclined surface 426, a first opposing surface 430, and a third opposing surface 432. Hereinafter, members having the same names as those in Embodiment 3 have the same configurations and functions as the members described in Embodiment 3, and detailed descriptions thereof are omitted.

[0275] The first lever 416 is rotatable about a first rotation axis 417, and has a first pressed portion 434 and a first restricting portion 436. The first biasing member 420A biases the first lever 416 in the rotation direction R10. The first support portion 421A is a shaft-like member that supports one end of the spring-like first biasing member 420A, and is attached to the pedestal 404 together with the first rotation axis 417. The first stopper 422 restricts further rotation of the first lever 416 biased by the first biasing member 420A in the rotation direction R10.

[0276] The second pusher 400B has a second pressing surface 414B, a second inclined surface 428, a second opposing surface 431, and a fourth opposing surface 433.

[0277] The second lever 418 is rotatable about a second rotation axis 419 and has a second pressed portion 438 and a second restricting portion 440. The second biasing member 420B biases the second lever 418 in the rotation direction R11. The second support portion 421B is a shaft-shaped member that supports one end of the spring-like second biasing member 420B and is attached to the pedestal 404 together with the second rotation axis 419. The second stopper 424 restricts further rotation of the second lever 418 biased by the second biasing member 420B in the rotation direction R11.

[0278] As shown in FIG. 45A, in a state where the pushers 400A and 400B are in the retracted positions (when not operating), the component holding tape 4 is conveyed in the conveying direction A, and one component 3 stops at the first correction position P5, and the adjacent component 3 stops at the second correction position P6. With the stop of the component 3, the pushers 400A and 400B are driven in the pressing direction G3.

[0279] When the pushers 400A and 400B move in the pressing direction G3, the first pressing surface 414A of the first pusher 400A passes between the two leads 3R of the component 3 at the first correction position P5 and advances toward the first pressed portion 434 of the first lever 416. Similarly, the second pressing surface 414B of the second pusher 400B passes between the two leads 3R of the component 3 at the second correction position P6 and advances toward the second pressed portion 438 of the second lever 418.

[0280] As shown in FIG. 45B, the first pressing surface 414A of the first pusher 400A presses the first lever 416, causing the first lever 416A to rotate in the rotation direction R12. The first restricting portion 436 of the first lever 416 positions the rear lead 3R of the component 3 between itself and the first opposing surface 430 (FIG. 45A) of the advanced first pusher 400A. The lead 3R is also sandwiched between the third opposing surface 432 of the first pusher 400A and the first pusher 422, restricting horizontal movement.

[0281] Similarly, the second pressing surface 414B of the second pusher 400B presses the second lever 418, causing the second lever 418 to rotate in the rotational direction R13. The second restricting portion 440 of the second lever 418 is positioned between the second opposing surface 431 (FIG. 45A) of the advanced second pusher 400B, sandwiching the front lead 3R of the component 3 therebetween. The lead 3R is also sandwiched between the fourth opposing surface 433 of the second pusher 400B and the second pusher 424, restricting its movement in the horizontal direction.

[0282] According to the above operation, the rear lead 3R of the component 3 at the first correction position P5 is positioned at a predetermined position, and the front lead 3R of the component 3 at the second correction position P6 is positioned at a predetermined position. Thereby, the posture of the component 3 can be corrected at each of the correction positions P5 and P6, and the pitch of the final two leads 3R can be adjusted to a desired length. Further, by sequentially stopping the component 3 at the first correction position P5 and the second correction position P6, even if the component 3 is tilted forward or backward, the posture of the component 3 can be corrected toward an upright posture while considering springback.

[0283] As described above, the present invention has been described with reference to the above-described Embodiments 1 to 3, but the present invention is not limited to the above-described Embodiments 1 to 3. For example, both the posture correction mechanism 40A of Embodiment 1 and the lead pitch adjustment mechanism 40B of Embodiment 2 may be provided in the same component supply device 13. Thereby, the pitch of the lead 3R can be adjusted while correcting the posture of the component 3 in the middle of the transport path TR.

[0284] Although the present disclosure has been fully described in connection with preferred embodiments with reference to the accompanying drawings, various modifications and variations will be apparent to those skilled in the art. Such modifications and variations are to be understood as being included therein as long as they do not depart from the scope of the present disclosure as defined by the appended claims. Also, changes in the combination and order of elements in each embodiment can be realized without departing from the scope and spirit of the present disclosure.

[0285] In addition, among the above-described embodiments and various modifications, by appropriately combining any of the embodiments and modifications, it is possible to achieve the respective effects.
