[0011] Hereinafter, exemplary embodiments of a component supply device, a component mounting machine 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 idea are included in the present invention.

[0012] (Embodiment) FIG. 1 shows a component mounting machine 1 according to an embodiment of the present invention. The component mounting machine 1 is a device that mounts a component 3 on a substrate 2. The component mounting machine 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 mounting machine 1 as viewed from 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.

[0013] 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.

[0014] In FIG. 1, each of the component supply devices 13 includes a component supply port 13K on the tip side and continuously supplies the component 3 to a pickup position 13P (see FIG. 2) directly below the component supply port 13K. In the embodiment, the component 3 supplied by the component supply device 13 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.

[0015] 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 an imaging field directed upward and images the component 3 picked up by the component mounting mechanism 15 from below.

[0016] In Figure 1, the component mounting mechanism 15 comprises a head moving mechanism 21 provided on the base 11 and a mounting head 22 moved by the head moving mechanism 21. The head moving mechanism 21 comprises a fixed table 21a, a movable table 21b, and a movable plate 21c. The fixed table 21a is fixed to the base 11, and the movable table 21b is provided to move along the fixed table 21a in the Y-axis direction. The movable plate 21c is provided to move along the movable table 21b in the X-axis direction, and the mounting head 22 is attached to the movable plate 21c. The mounting head 22 is movable horizontally by the movement of the movable table 21b and the movable plate 21c.

[0017] In Figure 1, the mounting head 22 is equipped with multiple suction nozzles 22a. Each suction nozzle 22a extends downward, with its lower end serving as a component suction port, and is configured to move up and down along the Z-axis. The mounting head 22 is equipped with a suction control mechanism 22b, which is connected to a vacuum source (not shown). The suction control mechanism 22b generates a vacuum suction force at the component suction ports of each suction nozzle 22a by controlling the vacuum pressure supplied from the vacuum source.

[0018] The head movement mechanism 21 moves the mounting head 22 above the parts supply port 13K of the parts supply device 13, then lowers the suction nozzle 22a, bringing the body 3B of the parts 3 into contact with the lower end of the suction nozzle 22a for vacuum suction. This picks up the parts 3 supplied to the pickup position 13P (see Figures 2 and 3).

[0019] The control unit 16 is a component for controlling the operation of the component mounting machine 1. The control unit 16 is electrically connected to each component of the component mounting machine 1 and controls the operation of each component. The control unit 16 has, for example, a microcomputer. The control unit 16 displays information regarding the operating status of the component mounting machine 1 on the touch panel 101 and accepts input from the operator OP.

[0020] In Figure 2, each parts supply device 13 has a base portion 31 connected to a trolley 11D (see Figure 1) and a cover portion 32 attached to the base portion 31. A parts holding tape 4 is provided within the area covered by the cover portion 32 on the base portion 31. The parts holding tape 4 is a tape-shaped member that holds the leads 3R of multiple parts 3 and travels in a pitch direction A along the transport path TR provided inside the cover portion 32 in the Y-axis direction.

[0021] As shown in Figure 2, a first drive source 34 for pitching the parts holding tape 4 is provided inside the parts supply device 13. The first drive source 34 in this embodiment is a cylinder having an output shaft 35, which drives the output shaft 35 back and forth along the transport direction A. The first drive source 34 is driven and controlled by the control unit 16.

[0022] The control unit 16 controls the first drive source 34 to perform the feeding operation of the component 3 intermittently, and intermittently supplies the component 3 to the pickup position 13P.

[0023] The parts supply device 13 shown in Figure 2 is equipped with a kink formation mechanism 40 as a mechanism for forming kinks in the lead 3R of the parts 3 being transported along the transport path TR. In Figure 2, the approximate location of the kink formation mechanism 40 is shown by a dotted line, and the specific configuration is not illustrated.

[0024] By providing the parts supply device 13 with a kink formation mechanism 40, a kink can be formed in the lead 3R of the parts 3 along the transport path TR, thereby improving the supply efficiency of the parts 3 by the parts supply device 13.

[0025] The configuration and operation of the kink formation mechanism 40 will be explained below using the drawings from Figure 4 onward.

[0026] Figures 4 and 5 are perspective and plan views, respectively, of the kink-forming mechanism 40 in the embodiment. Figures 6 and 7 are perspective views, respectively, showing the movable guide 44 and fixed guide 46 of the kink-forming mechanism 40, with some of the components omitted from the illustration.

[0027] The kink-forming mechanism 40 comprises 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 main body 43 of the device that forms the transport path TR.

[0028] The movable guide 44 and the fixed guide 46 are components that sandwich the lead 3R of part 3 between them to form a kink in the lead 3R of part 3.

[0029] The movable guide 44 is a guide section configured to be movable in the lateral direction B, which is a direction intersecting the transport direction A. In this embodiment, the lateral direction B is a horizontal direction perpendicular to the transport direction A and corresponds to the X-axis direction. The fixed guide 46 is positioned opposite the movable guide 44 across the transport path TR and is fixed to the main body of the device 43.

[0030] The region between the movable guide 44 and the fixed guide 46 includes a pitch adjustment position P1 for adjusting the pitch of the lead 3R and a kink formation position P2 for forming a kink. The pitch adjustment position P1 is located on the upstream side A1, and the kink formation position P2 is located on the downstream side A2. The part 3 stops at the pitch adjustment position P1, then is sent to the downstream side A2, and stops at the kink formation position P2. In this embodiment, the pitch adjustment position P1 and the kink formation position P2 are located two pitches apart.

[0031] 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 different drive source from the first drive source 34 (Figure 2) described above, and has an output shaft 49 that can be driven along the conveying direction A. In this embodiment, the second drive source 48 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.

[0032] The cam mechanism 50 is a mechanism for converting the driving force along the transport direction A from 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 comprises 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 a projection 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 transport direction A, the cam follower 56 moves along the lateral direction B. The cam follower 56 is mounted on the device body 43 in a state where it can move in the lateral direction B but its movement in the forward and backward direction is restricted.

[0033] With this configuration, when the second drive source 48 drives the output shaft 49 back and forth along the transport 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. This allows the movable guide 44 connected to the cam follower 56 to reciprocate in the lateral direction B. Figures 4 and 5 show the state in which the movable guide 44 is close to the fixed guide 46 (forward state), and Figures 6 and 7 show the state in which the movable guide 44 is away from the fixed guide 46 (retracted state).

[0034] As shown in Figures 6 and 7, the movable guide 44 has two types of contact portions 60 and 62 that contact the lead 3R of the part 3. Contact portion 60 is provided at the pitch adjustment position P1, and contact portion 62 is provided at the kink formation position P2. When contact portion 60 contacts the lead 3R of the part 3 at the pitch adjustment position P1, it functions to adjust the pitch of the lead 3R, and when contact with the lead 3R of the part 3 at the kink formation position P2, it functions to bend a part of the lead 3R to form a kink.

[0035] Here, the detailed configuration of the movable guide 44 will be explained using Figures 8 and 9. Figures 8 and 9 are perspective views showing the movable guide 44.

[0036] As shown in Figures 8 and 9, the contact portion 60 of this embodiment has two claw portions 60A and 60B. Each of the claw portions 60A and 60B has a shape that protrudes laterally in the direction B toward the lead 3R (not shown) of the component 3, and is a pair of claw portions provided spaced apart along the transport direction A. The claw portions 60A and 60B of this embodiment contact the two leads 3R of the component 3 at the pitch adjustment position P1 so as to sandwich them in the transport direction A, and function to narrow the pitch of the leads 3R to a predetermined pitch or less.

[0037] The claw portion 60A has an inclined portion 64A and a non-inclined portion 65A, and the claw portion 60B has an inclined portion 64B and a non-inclined portion 65B.

[0038] Both the inclined sections 64A and 64B are surfaces that are inclined in both the transport direction A and the lateral direction B when viewed from above. The non-inclined sections 65A and 65B are surfaces that extend in the lateral direction B when viewed from above.

[0039] The inclined portion 64A contacts the rear (upstream A1) lead 3R of the two leads 3R of the part 3 at the pitch adjustment position P1. The inclined portion 64B contacts the front (downstream A2) lead 3R of the two leads 3R of the part 3 at the pitch adjustment position P1. The inclined portion 64A has a tapered shape that slopes away from the fixed guide 46 as it moves downstream A2 in the transport direction A, and the inclined portion 64B has a tapered shape that slopes away from the fixed guide 46 as it moves upstream A1 in the transport direction A.

[0040] The non-inclined portion 65A extends laterally in direction B inside the inclined portion 64A and connects to the inclined portion 64A. The non-inclined portion 65B extends laterally in direction B inside the inclined portion 64B and connects to the inclined portion 64B. By providing the non-inclined portions 65A and 65B, the pitch of the lead 3R of the component 3 is restricted from widening after contact with the inclined portions 64A and 64B.

[0041] The distance L1 between the non-sloping sections 65A and 65B shown in Figure 9 is set based on the desired pitch length of the lead 3R. In this embodiment, taking into account the springback of the lead 3R, the distance L1 between the non-sloping sections 65A and 65B is set to be shorter than the desired pitch length of the lead 3R.

[0042] While the contact portion 60 is composed of two claw portions 60A and 60B, the contact portion 62 is composed of one claw portion. The contact portion 62 has a tapered shape (inclined shape) that narrows towards the tip. In this embodiment, the contact portion 62 contacts the two leads 3R of the component 3 at the kink formation position P2 from the inside, bending a part of the leads 3R outwards to form a kink.

[0043] The contact portion 62 has two inclined portions 66A and 66B and a tip surface 68.

[0044] Both inclined sections 66A and 66B are surfaces that are inclined with respect to both the transport direction A and the lateral direction B in a plan view. Inclined section 66A contacts the rear (upstream A1) lead 3R of the two leads 3R of the part 3 at the kink formation position P2, and inclined section 66B contacts the front (downstream A2) lead 3R of the two leads 3R of the part 3 at the kink formation position P2. Inclined section 66A has a shape that is inclined away from the fixed guide 46 as it moves towards the upstream A1 in the transport direction A, and inclined section 66B has a shape that is inclined away from the fixed guide 46 as it moves towards the downstream A2 in the transport direction A.

[0045] Each of the inclined portions 66A and 66B has a shape in which a portion (the central portion) in the Z direction protrudes outward. By providing protrusions on the inclined portions 66A and 66B and bringing these protrusions into contact with the lead 3R of the component 3, it becomes easier to form a kink by bending only a portion of the lead 3R rather than bending the entire lead 3R.

[0046] The tip surface 68 is the surface that constitutes the tip of the contact portion 62. The tip surface 68 is positioned opposite the recess 72 of the fixed guide 46, which will be described later, and performs the opening and closing operation of the shutter members 74A and 74B.

[0047] Returning to Figure 7, the fixed guide 46 forms two types of recesses 70 and 72. The recesses 70 and 72 each form a space for accommodating the contact portions 60 and 62 of the movable guide 44 when the movable guide 44 approaches. The recess 70 is provided at the pitch adjustment position P1 to accommodate the contact portion 60, and the recess 72 is provided at the kink formation position P2 to accommodate the contact portion 62.

[0048] Here, the detailed configuration of the fixed guide 46 will be explained using Figures 10 and 11. Figure 10 is a perspective view showing the fixed guide 46, and Figure 11 is a front view showing an enlarged view of the recess 72 of the fixed guide 46.

[0049] As shown in Figure 10, the recess 70 is continuously formed to have a width sufficient to accommodate a pair of claw portions 60A and 60B (not shown) of the contact portion 60. When the claw portions 60A and 60B are positioned in the recess 70, they do not come into contact with the fixed guide 46.

[0050] The recess 72 is formed continuously to have a width sufficient to accommodate the contact portion 62 (not shown). The recess 72 forms an opening corresponding to the front surface 68 of the contact portion 62 and has a tapered shape that narrows towards the back. The inside of the recess 72 has an inclined shape corresponding to the inclined shapes of the inclined portions 66A and 66B of the contact portion 62.

[0051] The recess 72 is composed of a pair of shutter members 74A and 74B. The shutter members 74A and 74B are a pair of members configured to open and close in a direction along the transport direction A (Y direction) in response to contact with the contact portion 62.

[0052] The shutter members 74A and 74B each have opposing surfaces 76A and 76B. The opposing surfaces 76A and 76B are surfaces that are positioned to face the lead 3R of the component 3 in the lateral direction B, and receive and support the lead 3R which is pressed by the contact portion 62.

[0053] When the inclined portions 66A and 66B of the contact portion 62 press against the lead 3R, the lead 3R is pressed in a direction that expands along the transport direction A, and also in the lateral direction B. By supporting the lead 3R in the lateral direction B with the opposing surfaces 76A and 76B, deformation of the lead 3R in the lateral direction B is prevented, making it easier to bend it in the transport direction A, and thus facilitating the formation of a kink.

[0054] The shutter members 74A and 74B are biased in the closing direction (arrows C1 and C2) by a biasing member (not shown).

[0055] Here, the operation of shutter members 74A and 74B will be explained using Figure 11. As shown in Figure 11(a), in the non-contact state where the contact portion 62 does not contact the shutter members 74A and 74B, the shutter members 74A and 74B remain closed (arrows C1 and C2). At this time, the opening area of ​​the recess 72 is smallest, and the opposing surfaces 76A and 76B around the recess 72 are exposed over the widest area. As shown by the dotted line, when the lead 3R pressed by the contact portion 62 is positioned, the opposing surfaces 76A and 76B receive and support the lead 3R.

[0056] Subsequently, as the movable guide 44 moves forward toward the fixed guide 46, the tip surface 68 of the contact portion 62 enters the opening of the recess 72. As shown in Figure 11(b), the shutter members 74A and 74B are pushed outward by contact with the contact portion 62 (arrows D1 and D2). Even though the shutter members 74A and 74B are spread apart, the lead 3R does not enter the recess 72 because the contact portion 62 is embedded in the recess 72, and remains supported by the opposing surfaces 76A and 76B. As shown by the dotted line, when a kink 3K is formed on the lead 3R, the opposing surfaces 76A and 76B face the entire lead 3R including the kink 3K.

[0057] According to the above operation, the shutter members 74A and 74B open in response to contact with the contact portion 62, thereby widening the surface area that receives the lead 3R with the opposing surfaces 76A and 76B, and allowing the contact portion 62 to advance further inward, making it easier to bend the lead 3R outward.

[0058] As shown in Figure 11, recesses 77A and 77B are formed in front of the opposing surfaces 76A and 76B. The recesses 77A and 77B are recesses for accommodating the lead 3R that has been pressed by the contact portion 62. Each of the recesses 77A and 77B has a shape in which a portion of it flares outward, corresponding to the location where the kink 3K is formed.

[0059] Although not shown in Figures 6 and 7, the movable guide 44 is provided with auxiliary members to assist in lead pitch adjustment and kink formation operations. The configuration and operation of the auxiliary members will be explained using Figures 12 to 14B.

[0060] Figure 12 is a perspective view showing the area around the movable guide 44 and the fixed guide 46, and Figures 13A and 13B are side views of the same area viewed along the transport direction A.

[0061] As shown in Figure 12, the movable guide 44 is fitted with a mounting portion 82, a first pressing portion 84, and a second pressing portion 86.

[0062] The mounting portion 82 is a component for attaching the first pressing portion 84 and the second pressing portion 86 to the movable guide 44. By attaching the first pressing portion 84 and the second pressing portion 86 to the movable guide 44 using the mounting portion 82, the first pressing portion 84 and the second pressing portion 86 move integrally with the movable guide 44 in the lateral direction B.

[0063] The first pressing portion 84 is a member for pressing the body 3B of the part 3, which is at the kink formation position P2, toward the fixing guide 46. When the first pressing portion 84 presses the body 3B of the part 3 in the lateral direction B, the entire part 3 is pressed toward the fixing guide 46.

[0064] The second pressing section 86 is a member for pressing the body 3B of the part 3, which is at the kink formation position P2, in the opposite direction to the first pressing section 84. The second pressing section 86 has a roughly L-shaped cross-section and extends to a position on the opposite side of the transport path TR from the first pressing section 84. After the body 3B of the part 3 is pressed toward the fixed guide 46 by the first pressing section 84, when the movable guide 44 retracts, the body 3B is pressed toward the transport path TR by the second pressing section 86 in a direction away from the fixed guide 46.

[0065] In this embodiment, the first pressing portion 84 is configured to be rotatable about a rotation axis Ax that passes through the mounting portion 82. The first pressing portion 84 is further biased in the rotation direction R1 by a biasing member such as a spring, and remains stationary in a biased state up to a predetermined stop position. When an external force opposite to the rotation direction R1 is applied to the first pressing portion 84, the first pressing portion 84 can rotate in the opposite direction to the rotation direction R1. On the other hand, the second pressing portion 86 is fixed to the mounting portion 82 and cannot move relative to the mounting portion 82.

[0066] According to the above configuration, as shown in Figure 13A, when the movable guide 44 is retracted (arrow E1), the part 3 at the kink formation position P2 is positioned between the first pressing part 84 and the second pressing part 86. The first pressing part 84 is biased toward the body 3B of the part 3 (arrow R1), but stops in a position before contact with the body 3B.

[0067] As shown in Figure 13B, when the movable guide 44 moves forward toward the fixed guide 46 (arrow E2), the first pressing part 84 contacts the body 3B of the part 3 and presses the body 3B toward the fixed guide 46 (arrow E2). By bringing the contact part 62 into contact with the lead 3R while the body 3B of the part 3 is pressed against the fixed guide 46, the lead 3R is more easily bent outward to form a kink 3K. At this time, since the first pressing part 84 is rotatable in the direction opposite to the biasing force (arrow R2), it is possible to press the body 3B toward the fixed guide 46 with sufficient force while preventing excessive pressure from being applied to the body 3B. This helps to suppress damage to the part 3.

[0068] Subsequently, when the movable guide 44 retracts, the state returns to that shown in Figure 13A (arrow E1). At this time, the body 3B of part 3 is pressed by the second pressing part 86 (arrow E1) and returns to its original position.

[0069] In this embodiment, the direction of movement of the movable guide 44 is set to be oblique to the horizontal direction. As shown in Figure 13B, when the movable guide 44 moves forward toward the fixed guide 46, it moves diagonally downward (arrow E2), and as shown in Figure 13A, when it moves away from the fixed guide 46, it moves diagonally upward (arrow E1). This prevents the movable guide 44 from lifting the part 3 when it moves forward and contacts the lead 3R of the part 3, thereby suppressing the load on the part 3.

[0070] Returning to Figure 12, a separate fixed guide 90 is provided at the pitch adjustment position P1, distinct from the fixed guide 46. The fixed guide 90 is a guide located on the opposite side of the transport path TR from the fixed guide 46. The fixed guide 90 is at the same height as the body 3B of the part 3 and guides the body 3B of the part 3, which is being transported in the transport direction A, to the predetermined position at the pitch adjustment position P1. By providing the fixed guide 90, the position of the part 3 can be stabilized.

[0071] The operation of the kink-forming mechanism 40 having the above-described configuration will be explained using Figures 14A and 14B. Figures 14A and 14B are perspective views illustrating the operation of the kink-forming mechanism 40, and the auxiliary members shown in Figures 13A and 13B are omitted from the illustration.

[0072] As shown in Figure 14A, when the movable guide 44 is retracted (arrow E1), neither the contact portion 60 nor 62 is in contact with the lead 3R of the part 3. At this time, neither the part 3 at the pitch adjustment position P1 nor the part 3 at the kink formation position P2 is being pressed toward the fixed guide 46, and they are aligned in a line with the other parts 3 along the transport path TR.

[0073] As shown in Figure 14B, when the movable guide 44 moves forward toward the fixed guide 46 (arrow E2), the contact portions 60 and 62 move together, so that contact portion 60 comes into contact with the lead 3R of the component 3 at the pitch adjustment position P1, and contact portion 62 comes into contact with the lead 3R of the component 3 at the kink formation position P2.

[0074] As shown in Figures 8 and 9, the contact portion 60 has a pair of claw portions 60A and 60B, and at the pitch adjustment position P1, the inclined portions 64A and 64B contact the two leads 3R from the outside, thereby narrowing the pitch of the leads 3R to a predetermined interval or less.

[0075] Furthermore, the contact portion 62, which is composed of a single claw, has inclined portions 66A and 66B that contact the two leads 3R from the inside, causing a portion of the leads 3R to bend outward at the kink formation position P2, thereby forming a kink 3K. At the kink formation position P2, the part 3 has its body 3B pressed against the fixed guide 46 by the second pressing portion 86 (see Figure 13B), and the inclined portions 66A and 66B of the contact portion 62 contact the leads 3R, forming a kink 3K.

[0076] As shown in Figure 11, the lead 3R of part 3 is positioned in the recesses 77A and 77B of the fixed guide 46 and pressed against the opposing surfaces 76A and 76B by the pressure of the contact portion 62. As the contact portion 62 moves forward toward the lead 3R with the opposing surfaces 76A and 76B supporting it from opposite sides, it becomes easier to bend the lead 3R along the transport direction A and form a kink 3K. As mentioned above, the inclined portions 66A and 66B of the contact portion 62 have a shape in which the central part protrudes outward, making it easy to bend a part of the lead 3R and form a kink 3K.

[0077] As shown in Figure 11, as the movable guide 44 moves forward, the tip surface 68 of the contact portion 62 enters the recess 72 of the fixed guide 46, and the pair of shutter members 74A and 74B open outwards (arrows D1 and D2). The shutter members 74A and 74B are biased to close when the movable guide 44 is not in contact (arrows C1 and C2), and open in response to contact with the contact portion 62. This allows the contact portion 62 to be moved further inward while securing a wider area for the opposing surfaces 76A and 76B that support the lead 3R of the component 3, making it easier to form the kink 3K.

[0078] As the movable guide 44 moves forward, the leads 3R of part 3 can be machined into the desired shape at both the pitch adjustment position P1 and the kink formation position P2, as shown in Figure 15. At the pitch adjustment position P1, the pitch of the two leads 3R of part 3 is adjusted to a predetermined length (e.g., pitch L2) or less, and at the kink formation position P2, a kink 3K is formed on the two leads 3R of part 3.

[0079] In the example shown in Figure 15, an intermediate position P3 is provided between the pitch adjustment position P1 and the kink formation position P2. When a component 3 at the pitch adjustment position P1 is advanced by one pitch, it stops at the intermediate position P3, and when it is advanced by another pitch, it stops at the kink formation position P2. The provision of the intermediate position P3 allows for the handling of cases where components 3 are thinned out and positioned and advanced by pitch on the component holding tape 4.

[0080] Subsequently, when the movable guide 44 retracts, the state returns to that shown in Figure 14A. As the movable guide 44 retracts, the body 3B of the part 3 at the kink formation position P2 is pressed away from the fixed guide 46 by the second pressing part 86 (see Figure 13A). As a result, the part 3 returns to its predetermined position in the transport path TR.

[0081] Furthermore, although the component 3 at the pitch adjustment position P1 moves slightly in the lateral direction B due to contact with the contact portion 60, it is held in place by the pair of claw portions 60A and 60B, and moves integrally with the contact portion 60, making it easy to return to its original position.

[0082] When the system returns to the state shown in Figure 14A, the first drive source 34 moves the part 3 by one pitch. The next part 3 stops at the pitch adjustment position P1 and the kink formation position P2, respectively. In this state, the second drive source 48 moves the movable guide 44 back and forth, performing the same lead processing on both the part 3 at the pitch adjustment position P1 and the part 3 at the kink formation position P2.

[0083] By alternately performing the pitch feeding operation of the component 3 by the first drive source 34 and the reciprocating operation of the movable guide 44 by the second drive source 48, kinks 3K can be sequentially formed on the lead 3R of the component 3 while the component 3 is being fed by pitch (see Figure 15).

[0084] With the above configuration, by using the movable guide 44 and the fixed guide 46, a kink 3K can be formed on the lead 3R of the part 3 traveling along the transport path TR. Compared to the conventional technology, which involves manually fitting together a mold with a convex portion and a mold with a concave portion, the formation of the kink 3K can be performed automatically, improving the supply efficiency of the part 3.

[0085] Furthermore, by providing a pitch adjustment position P1 upstream of the kink formation position P2, and adjusting the pitch of lead 3R before forming kink 3K, it becomes easier to form kink 3K into the desired shape.

[0086] As described above, the component supply device 13 of the embodiment includes a transport path TR that transports the component 3 toward the pickup position 13P in the transport direction A, and a kink forming mechanism 40 that forms a kink 3K on the lead 3R of the component 3 along the transport path TR. The kink forming mechanism 40 also includes a movable guide 44 that can move in the lateral direction B intersecting the transport direction A, and a fixed guide 46 that faces the movable guide 44 across the transport path TR. The movable guide 44 has a contact portion 62 that can contact the lead 3R of the component 3 when it moves toward the component 3, and the contact portion 62 has inclined portions 66A and 66B that are inclined in a direction that bends a part of the contacted lead 3R outward.

[0087] With this configuration, a kink 3K can be formed on the lead 3R of part 3 along the transport path TR, improving the supply efficiency of part 3 compared to conventional devices where molds are manually fitted together.

[0088] Furthermore, according to the component supply device 13 of the embodiment, the fixed guide 46 has opposing surfaces 76A and 76B that face the lead 3R of the component 3. The opposing surfaces 76A and 76B receive and support the lead 3R of the component 3 from the opposite side when the contact portion 62 of the movable guide 44 contacts the lead 3R of the component 3. With this configuration, the lead 3R of the component 3 is supported by the opposing surfaces 76A and 76B, and by bending the lead 3R, it becomes easier to bend the lead 3R in the desired direction.

[0089] Furthermore, according to the component supply device 13 of this embodiment, the opposing surfaces 76A and 76B have a shutter function that opens in response to contact with the movable guide 44. With this configuration, by opening the opposing surfaces 76A and 76B when the movable guide 44 moves forward, it is possible to advance the movable guide 44 to a deeper position, making it easier to bend the lead 3R, while securing a surface for receiving the lead 3R of the component 3.

[0090] Furthermore, according to the component supply device 13 of this embodiment, the fixed guide 46 is biased in the direction of closing the opposing surfaces 76A and 76B. With this configuration, when the movable guide 44 makes contact and the opposing surfaces 76A and 76B open, it can be operated so that only a minimum area is opened.

[0091] Furthermore, according to the component supply device 13 of this embodiment, the movable guide 44 moves diagonally downward when approaching the component 3 and diagonally upward when moving away from the component 3. With this configuration, when the movable guide 44 comes into contact with the lead 3R of the component 3, it becomes difficult to lift the component 3 upward, thereby suppressing the load on the component 3.

[0092] Furthermore, according to the component supply device 13 of this embodiment, the movable guide 44 has a pressing portion (first pressing portion) 84 that presses the body 3B of the component 3 toward the fixed guide 46 when it moves toward the component 3. With this configuration, the entire component 3 can be pressed toward the fixed guide 46, making it easier to form a kink 3K.

[0093] Furthermore, according to the component supply device 13 of this embodiment, the movable guide 44 has a pressing portion (second pressing portion) 86 that presses the body 3B of the component 3 away from the fixed guide 46 when it moves away from the component 3. With this configuration, the component 3 that has been pressed by the fixed guide 46 can be returned to its original position.

[0094] Furthermore, according to the component supply device 13 of the embodiment, the movable guide 44 further has another contact portion 60 that contacts the lead 3R of the component 3 at a pitch adjustment position P1 located upstream of the kink formation position P2. The other contact portion 60 has inclined portions 64A and 64B that are inclined in a direction that narrows the pitch of the lead 3R of the component 3. With this configuration, by adjusting the pitch of the lead 3R upstream of the kink formation position P2, it becomes easier to form a kink 3K of the same shape at the kink formation position P2.

[0095] Furthermore, the component supply device 13 of this embodiment includes a first drive source 34 for feeding the component 3 along the transport path TR, and a second drive source 48 for driving the movable guide 44 in the lateral direction B. With this configuration, the feeding operation of the component 3 and the reciprocating drive of the movable guide 44 can be performed independently.

[0096] Furthermore, the component supply device 13 of this embodiment further includes a control unit 16, which intermittently performs the feeding operation of the component 3 by the first drive source 34, and drives the movable guide 44 by the second drive source 48 while the feeding of the component 3 by the first drive source 34 is stopped. With this configuration, it is possible to prevent unnecessary interference of the component 3 by the movable guide 44.

[0097] Furthermore, the component mounting machine 1 of this embodiment includes a component supply device 13 having a kink formation mechanism 40 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 to the substrate 2. With a component mounting machine 1 configured in this way, the same effects as the component supply device 13 having a kink formation mechanism 40 can be achieved.

[0098] Furthermore, the component supply method of the embodiment includes a transport step of transporting the component 3 toward the pickup position 13P along the transport path TR, and a kink forming step of forming a kink 3K on the lead 3R of the component 3 along the transport path TR. The kink forming step uses a kink forming mechanism 40 which includes a movable guide 44 that can move in a lateral direction B intersecting the transport direction A, and a fixed guide 46 that faces the movable guide 44 across the transport path TR. The mechanism moves the movable guide 44 toward the component 3, brings the inclined portions 66A and 66B provided on the movable guide 44 into contact with the lead 3R of the component 3, and bends a part of the contacted lead 3R outward to form a kink 3K.

[0099] This method can achieve the same effects as the component supply device 13 of the embodiment.

[0100] Although the present invention has been described above with reference to the embodiments described above, the present invention is not limited to the embodiments described above. For example, in this embodiment, the case in which the pitch of lead 3R is narrowed at the pitch adjustment position P1 and a part of lead 3R is bent outward at the kink formation position P2 to form a kink 3K was described, but the present invention is not limited to this case. For example, the pitch of lead 3R may be widened at the pitch adjustment position P1 and a part of lead 3R is bent inward at the kink formation position P2 to form a kink 3K. That is, the inclined portions 64A and 64B of the contact portion 60 should be inclined in a direction that widens or narrows the pitch of the contacted lead 3R, and the inclined portions 66A and 66B of the contact portion 62 should be inclined in a direction that bends a part of the contacted lead 3R outward or inward.

[0101] While this disclosure is adequately described in relation to preferred embodiments with reference to the accompanying drawings, various variations and modifications will be obvious to those skilled in the art. Such variations and modifications should be understood as being included within the scope of this disclosure as defined by the attached claims. Furthermore, variations in combinations and sequences of elements in each embodiment can be realized without departing from the scope and spirit of this disclosure.

[0102] Furthermore, by appropriately combining any of the above embodiments and various modifications, the effects of each can be achieved. [Industrial applicability]
