[0052] Hereinafter, exemplary embodiments of the component supply apparatus, the component mounting machine equipped with the component supply apparatus, and the component supply method of the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the specific structure of the following embodiments; structures based on the same technical concept are also included in the present invention.

[0053] (Implementation Method)

[0054] Figure 1 The component mounting machine 1 according to an embodiment of the present invention is shown. The component mounting machine 1 is an apparatus for assembling components 3 onto a substrate 2. The component mounting machine 1 includes a base 11, a substrate conveying mechanism 12, multiple component supply devices 13, a component camera 14, a component assembly mechanism 15, and a control unit 16. Here, for ease of explanation, the left-right direction of the component mounting machine 1 as observed from the operator OP is defined as the X-axis direction, the front-back direction as the Y-axis direction, and the up-down direction as the Z-axis direction.

[0055] exist Figure 1 In this system, the substrate conveying mechanism 12 uses a pair of conveyor mechanisms 12a to convey the substrate 2 along the X-axis direction, positioning it at a predetermined working position near the center of the base 11. Multiple component supply devices 13 are arranged on a trolley 11D mounted on the base 11.

[0056] exist Figure 1 In the middle, the component supply device 13 has a component supply port 13K on the front end side, and a pickup position 13P directly below the component supply port 13K (refer to...). Figure 2 The component 3 is continuously supplied by the component supply device 13. In this embodiment, the component 3 supplied by the component supply device 13 is a radial component with leads (radial tape component), such as... Figure 3 As shown, it has a cylindrical body 3B and two leads 3R extending downward from the body 3B.

[0057] exist Figure 1 In this configuration, the component camera 14 is positioned in the area between the substrate conveying mechanism 12 and the component supply device 13. The component camera 14 directs its field of view upwards to capture images of the component 3 picked up by the component assembly mechanism 15 from below.

[0058] exist Figure 1In this assembly mechanism 15, a head moving mechanism 21 is mounted on a base 11, and an assembly head 22 moves via the head moving mechanism 21. The head moving mechanism 21 includes a fixed worktable 21a, a movable worktable 21b, and a movable plate 21c. The fixed worktable 21a is fixed to the base 11, and the movable worktable 21b is movable along the fixed worktable 21a in the Y-axis direction. The movable plate 21c is movable along the movable worktable 21b in the X-axis direction, and the assembly head 22 is mounted on the movable plate 21c. The assembly head 22 moves freely in the horizontal direction by the movement of the movable worktable 21b and the movable plate 21c.

[0059] exist Figure 1 In the assembly head 22, there are 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 assembly head 22 has a suction control mechanism 22b, which is connected to a vacuum source (not shown). The suction control mechanism 22b controls the vacuum pressure supplied from the vacuum source, thereby generating a vacuum suction force at the component suction port of each suction nozzle 22a.

[0060] After the head moving mechanism 21 moves the assembly head 22 above the component supply port 13K of the component supply device 13, it 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 adsorption. This allows the component 3 supplied to the pick-up position 13P to be picked up (see reference). Figure 2 , Figure 3 ).

[0061] The control unit 16 is a component used to control 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 may include, for example, a microcomputer. The control unit 16 displays content related to the operating status of the component mounting machine 1 on the touch panel 101 and accepts input from the operator (OP).

[0062] exist Figure 2 In the middle, each component supply device 13 has a connection with the trolley 11D (see reference). Figure 1 The base portion 31 is connected to the base portion 31, and the cover portion 32 is mounted on the base portion 31. A component holding belt 4 is provided in the area covered by the cover portion 32 on the base portion 31. The component holding belt 4 is a strip-shaped member that holds the lead wires 3R of a plurality of components 3, and travels at intervals along the Y-axis in the conveying direction A on the conveying path TR provided inside the cover portion 32.

[0063] like Figure 2As shown, a first drive source 34 for maintaining the component's movement at a distance of 4 is provided inside the component supply device 13. In this embodiment, the first drive source 34 is a working cylinder having an output shaft 35, which drives the output shaft 35 back and forth along the conveying direction A. The first drive source 34 is driven and controlled by the control unit 16.

[0064] The control unit 16 controls the first drive source 34 to intermittently supply the component 3 to the pickup position 13P by intermittently performing the feeding operation of the component 3.

[0065] exist Figure 2 In the component supply device 13 shown, a bending forming mechanism 40 is provided as a mechanism for bending the lead wire 3R of the component 3 conveyed along the conveying path TR. Figure 2 In the diagram, the approximate location of the bending forming mechanism 40 is shown by dashed lines, while the specific structure is omitted.

[0066] By providing a bending forming mechanism 40 in the component supply device 13, a bend can be formed in the lead wire 3R of the component 3 in the middle of the conveying path TR, thereby improving the supply efficiency of the component 3 based on the component supply device 13.

[0067] The following uses Figure 4 The following figures will illustrate the structure and operation of the bending forming mechanism 40.

[0068] Figure 4 , Figure 5 These are, respectively, a perspective view and a top view of the bending forming mechanism 40 of the embodiment. Figure 6 , Figure 7 The figures shown are perspective views of the movable guide 44 and the fixed guide 46, with some of the components of the bending forming mechanism 40 omitted.

[0069] The bending forming mechanism 40 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 mounted on the main body 43 of the device that forms the conveying path TR.

[0070] The movable guide 44 and the fixed guide 46 are components used to clamp the lead wire 3R of component 3 between them, thereby bending the lead wire 3R of component 3.

[0071] The movable guide 44 is a guide portion configured to move in the transverse direction B, which intersects the conveying direction A. In this embodiment, the transverse direction B is a horizontal direction orthogonal to the conveying direction A, corresponding to the X-axis direction. The fixed guide 46 is positioned opposite the movable guide 44 across the conveying path TR and is fixed to the main body 43 of the device.

[0072] The area between the movable guide 44 and the fixed guide 46 includes a spacing adjustment position P1 for adjusting the spacing of the lead wire 3R, and a bending formation position P2 for forming a bend. The spacing adjustment position P1 is located on the upstream side A1, and the bending formation position P2 is located on the downstream side A2. After stopping at the spacing adjustment position P1, the component 3 is conveyed to the downstream side A2 and stops at the bending formation position P2. In this embodiment, the spacing adjustment position P1 and the bending formation position P2 are set at positions separating the two spacings.

[0073] The second drive source 48 is a drive source for reciprocating the movable guide 44 along the transverse direction B. The second drive source 48 serves as a drive source for the aforementioned first drive source 34 ( Figure 2 The second drive source 48 of the embodiment is a working 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.

[0074] The cam mechanism 50 is a mechanism for converting the driving force along the conveying direction A based on the second drive source 48 into a lateral driving force 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 engaged with the cam 54 and connected to the movable guide 44. A cam groove 55 is formed at the front end 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 inclined shape when viewed from above, which causes the cam follower 56 to move laterally B when the cam 54 moves back and forth along the conveying direction A. The cam follower 56 is mounted on the main body 43 of the device in a state in which it can move laterally B and its movement in the back-and-forth direction is restricted.

[0075] According to this structure, when the second drive source 48 drives the output shaft 49 back and forth along the conveying direction A, the cam 54 moves back and forth, and the cam follower 56, which engages with the cam 54, reciprocates along the transverse direction B. This allows the movable guide 44, connected to the cam follower 56, to reciprocate along the transverse direction B. Figure 4 , Figure 5 The diagram shows the movable guide 44 approaching the fixed guide 46 (forward state). Figure 6 , Figure 7 The figure shows the movable guide 44 in a state away from the fixed guide 46 (retreat state).

[0076] like Figure 6 , Figure 7As shown, the movable guide 44 has two contact portions 60 and 62 that contact the lead wire 3R of the component 3. The contact portion 60 is provided in the spacing adjustment position P1, and the contact portion 62 is provided in the bending formation position P2. The contact portion 60 functions to adjust the spacing of the lead wire 3R when it contacts the lead wire 3R of the component 3 in the spacing adjustment position P1, and the contact portion 62 functions to bend a portion of the lead wire 3R to form a bend when it contacts the lead wire 3R of the component 3 in the bending formation position P2.

[0077] Here, use Figure 8 , Figure 9 The detailed structure of the movable guide 44 is explained. Figure 8 , Figure 9 This is a perspective view showing the movable guide 44.

[0078] like Figure 8 , Figure 9 As shown, the contact portion 60 of this embodiment has two claw portions 60A and 60B. Claw portions 60A and 60B each have a shape that protrudes laterally along the B direction towards the lead wire 3R (not shown) of the component 3, and are a pair of claw portions spaced apart along the conveying direction A. In this embodiment, the claw portions 60A and 60B contact each other in such a way that they clamp the two lead wires 3R of the component 3 located at the spacing adjustment position P1 in the conveying direction A, thereby narrowing the spacing of the lead wires 3R to below a predetermined spacing.

[0079] Claw portion 60A has an inclined portion 64A and a non-inclined portion 65A, and claw portion 60B has an inclined portion 64B and a non-inclined portion 65B.

[0080] Inclined portions 64A and 64B are surfaces that are inclined relative to both the conveying direction A and the transverse direction B when viewed from above. Non-inclined portions 65A and 65B are surfaces that extend along the transverse direction B when viewed from above.

[0081] Inclined portion 64A contacts the rear (upstream A1) lead 3R of the two leads 3R of component 3 located at the pitch adjustment position P1. Inclined portion 64B contacts the front (downstream A2) lead 3R of the two leads 3R of component 3 located at the pitch adjustment position P1. Inclined portion 64A has a conical shape that is inclined towards the downstream A2 of the conveying direction A, moving further away from the fixed guide 46, while inclined portion 64B has a conical shape that is inclined towards the upstream A1 of the conveying direction A, moving further away from the fixed guide 46.

[0082] The non-inclined portion 65A extends laterally along B inside the inclined portion 64A and connects to the inclined portion 64A. The non-inclined portion 65B extends laterally along B inside the inclined portion 64B and connects to the inclined portion 64B. By providing the non-inclined portions 65A and 65B, the spacing of the lead wires 3R of the component 3 after contacting the inclined portions 64A and 64B is limited to a constant width.

[0083] Figure 9 The distance L1 between the non-tilted portions 65A and 65B shown is set based on the required spacing length of the lead 3R. In this embodiment, taking into account the springback of the lead 3R, the distance L1 between the non-tilted portions 65A and 65B is set to be shorter than the required spacing length of the lead 3R.

[0084] While contact portion 60 is composed of two claw portions 60A and 60B, contact portion 62 is composed of one claw portion. Contact portion 62 has a tapered shape (sloping shape) that becomes narrower towards the front end. In this embodiment, contact portion 62 contacts the two leads 3R of component 3 located at the bending formation position P2 from the inside, and bends a portion of the leads 3R outward to form a bend.

[0085] The contact portion 62 has two inclined portions 66A and 66B and a front end face 68.

[0086] Inclined portions 66A and 66B are both surfaces that are inclined relative to both the conveying direction A and the transverse direction B when viewed from above. Inclined portion 66A contacts the rear (upstream side A1) lead 3R of the two leads 3R of component 3 located at the bending formation position P2, and inclined portion 66B contacts the front (downstream side A2) lead 3R of the two leads 3R of component 3 located at the bending formation position P2. Inclined portion 66A has a shape that is inclined further away from the fixed guide 46 as it approaches the upstream side A1 of the conveying direction A, and inclined portion 66B has a shape that is inclined further away from the fixed guide 46 as it approaches the downstream side A2 of the conveying direction A.

[0087] The inclined portions 66A and 66B each have a shape in which a portion (central portion) protrudes outward in the Z direction. By providing the protrusions in the inclined portions 66A and 66B so that the protrusions come into contact with the lead wire 3R of the component 3, the lead wire 3R is not bent as a whole, but a portion of the lead wire 3R can be easily bent to form a bend.

[0088] The front end surface 68 is the surface that forms the front end of the contact portion 62. The front end surface 68 is positioned opposite the recess 72 of the fixed guide member 46 described later, and performs the opening and closing actions of the gate members 74A and 74B.

[0089] return Figure 7The fixed guide 46 forms two recesses 70 and 72. The recesses 70 and 72 respectively form spaces for accommodating the contact portions 60 and 62 of the movable guide 44 when the movable guide 44 approaches. The recess 70 is provided in the spacing adjustment position P1 to accommodate the contact portion 60, and the recess 72 is provided in the bending formation position P2 to accommodate the contact portion 62.

[0090] Here, use Figure 10 , Figure 11 The detailed structure of the fixed guide 46 is described below. Figure 10 This is a perspective view showing the fixed guide 46. Figure 11 This is a front view showing an enlarged view of the recess 72 of the fixed guide 46.

[0091] like Figure 10 As shown, the recess 70 is continuously formed in such a way that it has a pair of claw portions 60A and 60B (not shown) that are capable of accommodating the contact portion 60. When the claw portions 60A and 60B are disposed in the recess 70, the claw portions 60A and 60B do not contact the fixing guide 46.

[0092] The recess 72 is continuously formed in such a way that it is large enough to accommodate the contact portion 62 (not shown). The recess 72 forms an opening corresponding to the front end face 68 of the contact portion 62 and has a tapered shape that narrows towards the inner side. The inner side of the recess 72 has an inclined shape that corresponds to the inclined shape of the inclined portions 66A and 66B of the contact portion 62.

[0093] The recess 72 is composed of a pair of gate members 74A and 74B. The gate members 74A and 74B are a pair of members configured to open and close in the direction of conveying direction A (Y direction) in response to contact with the contact part 62.

[0094] Gate components 74A and 74B each have opposing surfaces 76A and 76B. The opposing surfaces 76A and 76B are arranged in a manner that they are opposite to the lead wire 3R of component 3 in the transverse direction B, and receive and support the lead wire 3R pressed by the contact part 62.

[0095] When the inclined portions 66A and 66B of the contact portion 62 press the lead wire 3R, the lead wire 3R is pressed in the direction of widening along the conveying direction A, and is also pressed in the transverse direction B. By using the opposing surfaces 76A and 76B to support the lead wire 3R in the transverse direction B, deformation of the lead wire 3R in the transverse direction B can be prevented and it can be easily bent in the conveying direction A, making it easy to form a bend.

[0096] Gate components 74A and 74B are subjected to force in the closing direction (arrows C1 and C2) by force-applying components not shown.

[0097] Here, use Figure 11The operation of gate components 74A and 74B is explained. For example... Figure 11 As shown in (a), in the non-contact state where the contact portion 62 is not in contact with the gate members 74A and 74B, the gate members 74A and 74B remain closed (arrows C1 and C2). At this time, the opening area of ​​the recess 72 becomes minimal, and the opposing surfaces 76A and 76B around the recess 72 are exposed with their maximum area. As shown by the dashed lines, if the lead wire 3R is arranged to be pressed by the contact portion 62, the opposing surfaces 76A and 76B receive and support the lead wire 3R.

[0098] Then, as the movable guide 44 moves toward the fixed guide 46, the front end face 68 of the contact portion 62 enters the opening of the recess 72. For example... Figure 11 As shown in (b), the gate members 74A and 74B are pushed outwards through contact with the contact portion 62 (arrows D1 and D2). Even though the gate members 74A and 74B widen, the lead wire 3R will not enter the recess 72 because the contact portion 62 is embedded in the recess 72, and will remain supported by the opposing surfaces 76A and 76B. As shown by the dashed line, with the lead wire 3R forming a bend 3K, the opposing surfaces 76A and 76B are completely opposed to the lead wire 3R including the bend 3K.

[0099] According to the above actions, the gate components 74A and 74B open in response to contact with the contact portion 62, thereby ensuring that the surface of the lead wire 3R received by the opposing surfaces 76A and 76B is larger, and the contact portion 62 can move further inward, thereby making it easier to bend the lead wire 3R outward.

[0100] like Figure 11 As shown, recesses 77A and 77B are formed in front of the opposing surfaces 76A and 76B. Recesses 77A and 77B are recesses for accommodating the lead wire 3R pressed by the contact portion 62. Recesses 77A and 77B each have a shape that widens outward in part corresponding to the portion where the bend 3K is formed.

[0101] Although Figure 6 , Figure 7 The illustration is omitted, but the movable guide 44 is equipped with auxiliary components to assist in the adjustment of the lead wire spacing and the bending formation action. Figures 12-14B The structure and operation of the auxiliary components are explained.

[0102] Figure 12 This is a perspective view showing the periphery of the movable guide 44 and the fixed guide 46. Figure 13A , Figure 13B This is a side view of the surrounding area when viewed along the conveying direction A.

[0103] like Figure 12As shown, the movable guide 44 is equipped with an installation part 82, a first pressing part 84, and a second pressing part 86.

[0104] The mounting part 82 is a component for mounting the first pressing part 84 and the second pressing part 86 to the movable guide 44. By using the mounting part 82 to mount the first pressing part 84 and the second pressing part 86 to the movable guide 44, the first pressing part 84 and the second pressing part 86 move integrally with the movable guide 44 along the lateral direction B.

[0105] The first pressing part 84 is a component used to press the main body 3B of the component 3, located at the bending formation position P2, toward the fixing guide 46. By pressing the main body 3B of the component 3 along the transverse direction B with the first pressing part 84, the entire component 3 is pressed toward the fixing guide 46.

[0106] The second pressing part 86 is a component used to press the main body 3B of the component 3, located at the bending formation position P2, in the opposite direction to the first pressing part 84. The second pressing part 86 has a generally L-shaped cross-sectional shape and extends to a position opposite to the first pressing part 84 across the conveying path TR. After the main body 3B of the component 3 is pressed towards the fixed guide 46 by the first pressing part 84, it is pressed back to the conveying path TR by the second pressing part 86 in a direction away from the fixed guide 46 when the movable guide 44 retracts.

[0107] In this embodiment, the first pressing part 84 is configured to rotate about a rotation axis Ax that passes through the mounting part 82. The first pressing part 84 is also subjected to force in the rotation direction R1 by a force-applying member such as a spring, and remains stationary at a predetermined stop position under this applied force. When an external force opposite to the rotation direction R1 is applied to the first pressing part 84, the first pressing part 84 can rotate in the opposite direction to R1. On the other hand, the second pressing part 86 is fixed to the mounting part 82 and cannot move relative to the mounting part 82.

[0108] Based on the above structure, such as Figure 13A As shown, with the movable guide 44 in a retracted state (arrow E1), the component 3, located at the bending formation position P2, is positioned between the first pressing part 84 and the second pressing part 86. Although the first pressing part 84 is subjected to force in the direction toward the body 3B of the component 3 (arrow R1), it stops at a position before contacting the body 3B.

[0109] like Figure 13BAs shown, when the movable guide 44 moves toward the fixed guide 46 (arrow E2), the first pressing part 84 contacts the main body 3B of the component 3, pressing the main body 3B toward the fixed guide 46 (arrow E2). By pressing the main body 3B of the component 3 against the fixed guide 46 and then contacting the lead wire 3R with the contact part 62, the lead wire 3R can be easily bent outward to form a bend 3K. At this time, the first pressing part 84 can rotate in the opposite direction to the force (arrow R2), thus pressing the main body 3B against the fixed guide 46 with sufficient force while avoiding excessive pressing force on the main body 3B. Therefore, damage to the component 3 can be suppressed.

[0110] Then, when the movable guide 44 retracts, it returns. Figure 13A The state shown is (arrow E1). At this time, the main body 3B of component 3 is pressed by the second pressing part 86 (arrow E1) and returns to its original position.

[0111] In this embodiment, the moving direction of the movable guide 44 is set to a direction inclined relative to the horizontal direction. For example... Figure 13B As shown, the movable guide 44 moves diagonally downwards (arrow E2) as it advances toward the fixed guide 46, as... Figure 13A As shown, when moving away from the fixed guide 46, it moves diagonally upward (arrow E1). Thus, when the movable guide 44 advances and contacts the lead wire 3R of the component 3, the component 3 is not lifted, and the load on the component 3 is suppressed.

[0112] return Figure 12 A fixed guide 90, different from the fixed guide 46, is provided at the spacing adjustment position P1. The fixed guide 90 is a guide part located on the opposite side of the fixed guide 46, across the conveying path TR. The fixed guide 90 is located at the same height as the main body 3B of the component 3, guiding the main body 3B of the component 3, which is conveyed along the conveying direction A, to the predetermined position of the spacing adjustment position P1. By providing the fixed guide 90, the position of the component 3 can be stabilized.

[0113] use Figure 14A , Figure 14B The operation of the bending forming mechanism 40 having the above structure will be explained. Figure 14A , Figure 14B This is a perspective view used to illustrate the operation of the bending forming mechanism 40; details are omitted. Figure 13A , Figure 13B The diagram shows the auxiliary components.

[0114] like Figure 14AAs shown, with the movable guide 44 in the retracted state (arrow E1), neither the contact portions 60 nor 62 are in contact with the lead wire 3R of component 3. At this time, neither component 3 in the spacing adjustment position P1 nor component 3 in the bending formation position P2 is pressed toward the fixed guide 46, and they are arranged in a row with other components 3 on the conveying path TR.

[0115] like Figure 14B As shown, when the movable guide 44 moves toward the fixed guide 46 (arrow E2), the contact parts 60 and 62 move together. The contact part 60 contacts the lead wire 3R of the component 3 located at the pitch adjustment position P1, and the contact part 62 contacts the lead wire 3R of the component 3 located at the bending formation position P2.

[0116] like Figure 8 , Figure 9 As shown, the contact portion 60 has a pair of claw portions 60A and 60B. In the spacing adjustment position P1, the inclined portions 64A and 64B contact the two leads 3R from the outside, thereby narrowing the spacing of the leads 3R to below the specified interval.

[0117] Additionally, the contact portion 62, which consists of a claw, contacts the two leads 3R from the inside via inclined portions 66A and 66B, thereby bending a portion of the leads 3R outward at the bending formation position P2 to form a bend 3K. The component 3 located at the bending formation position P2 is pressed against the body 3B by the second pressing portion 86 (see reference). Figure 13B When pressed against the fixed guide 46, the inclined portions 66A and 66B of the contact portion 62 come into contact with the lead wire 3R and form a bend 3K.

[0118] like Figure 11 As shown, the lead wire 3R of component 3 is disposed in the recesses 77A and 77B of the fixing guide 46, and is pressed against the opposing surfaces 76A and 76B by the pressing of the contact portion 62. With the opposing surfaces 76A and 76B supported from opposite sides, the contact portion 62 moves toward the lead wire 3R, thereby easily bending the lead wire 3R along the transport direction A to form a bend 3K. As described above, the inclined portions 66A and 66B of the contact portion 62 have a shape in which the central portion protrudes outward, thus making it easy to bend a part of the lead wire 3R to form a bend 3K.

[0119] like Figure 11As shown, as the movable guide 44 advances, the front end face 68 of the contact portion 62 enters the recess 72 of the fixed guide 46, and a pair of gate members 74A and 74B open outwards (arrows D1 and D2). The gate members 74A and 74B are respectively forced in the direction they are closed when not in contact with the movable guide 44 (arrows C1 and C2), and open accordingly upon contact with the contact portion 62. This ensures a wider area for the opposing surfaces 76A and 76B of the lead wire 3R used to support the member 3, and allows the contact portion 62 to move further inwards, making it easier to form the bend 3K.

[0120] By the forward movement of the movable guide 44, such as Figure 15 As shown, the lead wires 3R of component 3 can be processed into the desired shapes at the spacing adjustment position P1 and the bending formation position P2, respectively. For component 3 at the spacing adjustment position P1, the spacing between the two lead wires 3R is adjusted to a specified length (e.g., spacing L2) or less. For component 3 at the bending formation position P2, a bend 3K is formed on the two lead wires 3R.

[0121] exist Figure 15 In the example shown, an intermediate position P3 is provided between the spacing adjustment position P1 and the bending formation position P2. If the component 3 at the spacing adjustment position P1 is fed with one spacing, it stops at the intermediate position P3; if it is fed with another spacing, it stops at the bending formation position P2. By providing the intermediate position P3, it is also possible to handle situations where the component 3 is configured and fed with spacing in the component holding belt 4.

[0122] Then, if the movable guide 44 retracts, it returns. Figure 14A The state shown. As the movable guide 44 retracts, the main body 3B of component 3, located at the bending formation position P2, is pressed by the second pressing part 86 (see reference). Figure 13A Press the component 3 away from the fixed guide 46. As a result, component 3 returns to the designated position in the transport path TR.

[0123] It should be noted that the component 3, located at the pitch adjustment position P1, moves slightly in the lateral direction B through contact with the contact part 60, but becomes clamped by a pair of claws 60A and 60B, and moves together with the contact part 60, and can easily return to its original position.

[0124] When returning Figure 14A In the indicated state, component 3 is fed by a pitch amount via the first drive source 34. The subsequent components 3 stop at the pitch adjustment position P1 and the bending formation position P2, respectively. In this state, the second drive source 48 causes the movable guide 44 to reciprocate, thereby performing the same lead wire processing on both the component 3 at the pitch adjustment position P1 and the component 3 at the bending formation position P2.

[0125] By alternately performing the aforementioned pitch feeding action of component 3 by the first drive source 34 and the reciprocating action of movable guide 44 by the second drive source 48, it is possible to simultaneously perform pitch feeding on component 3 and sequentially form bends 3K on the lead wire 3R of component 3 (refer to...). Figure 15 ).

[0126] According to the above structure, by using the movable guide 44 and the fixed guide 46, a bend 3K can be formed on the lead wire 3R of the component 3 traveling in the conveying path TR. Compared with the structure in the prior art where the mold with the protrusion and the mold with the concave are manually fitted together, the bend 3K can be formed automatically, thereby improving the supply efficiency of the component 3.

[0127] In addition, a spacing adjustment position P1 is set on the upstream side of the bending formation position P2. The bending 3K is formed based on the adjustment of the spacing of the lead wire 3R, thereby making it easy to form the bending 3K into the desired shape.

[0128] As described above, the component supply device 13 of the embodiment has a transport path TR that transports the component 3 along the transport direction A toward the pickup position 13P, and a bending forming mechanism 40 that bends the lead wire 3R of the component 3 in the transport path TR by forming a bend 3K. Furthermore, the bending forming mechanism 40 includes a movable guide 44 that can move in a transverse direction B intersecting the transport direction A, and a fixed guide 46 that faces the movable guide 44 across the transport path TR. Additionally, the movable guide 44 has a contact portion 62 that can contact the lead wire 3R of the component 3 when moving toward the component 3, and the contact portion 62 has inclined portions 66A and 66B that are inclined outward in the direction in which a portion of the contacting lead wire 3R is bent.

[0129] According to this structure, the lead wire 3R of component 3 can be bent 3K in the middle of the conveying path TR, which can improve the supply efficiency of component 3 compared with the conventional structure in which the molds are manually fitted together.

[0130] Furthermore, according to the component supply device 13 of the embodiment, the fixing guide 46 has opposing surfaces 76A and 76B opposite to the lead wire 3R of the component 3. When the contact portion 62 of the movable guide 44 contacts the lead wire 3R of the component 3, the opposing surfaces 76A and 76B receive and support the lead wire 3R of the component 3 from opposite sides. With this structure, by bending the lead wire 3R of the component 3 in the state where it is received by the opposing surfaces 76A and 76B, the lead wire 3R can be easily bent in the desired direction.

[0131] Furthermore, according to the component supply device 13 of the embodiment, the opposing surfaces 76A and 76B have a gate function that opens in response to contact with the movable guide 44. With this structure, by opening the opposing surfaces 76A and 76B when the movable guide 44 moves forward, the surface for receiving the lead wire 3R of the component 3 is secured, and the movable guide 44 is moved to a deeper position, thereby making it easier to bend the lead wire 3R.

[0132] Furthermore, according to the component supply device 13 of the embodiment, the fixed guide 46 is forced in the direction of closing the opposing surfaces 76A and 76B. With this structure, when the movable guide 44 contacts and the opposing surfaces 76A and 76B open, the operation can be performed in a manner that minimizes the area that can be opened.

[0133] Furthermore, according to the component supply device 13 of the embodiment, the movable guide 44 moves obliquely downward when approaching the component 3 and obliquely upward when moving away from the component 3. With this structure, when the movable guide 44 contacts the lead wire 3R of the component 3, it is difficult to lift the component 3 upward, and the load on the component 3 can be suppressed.

[0134] Furthermore, according to the component supply device 13 of the embodiment, the movable guide 44 has a pressing part (first pressing part) 84 that presses the main body 3B of the component 3 toward the fixed guide 46 when it moves toward the component 3. With such a structure, the entire component 3 can be pressed toward the fixed guide 46, and a bend 3K can be easily formed.

[0135] Furthermore, according to the component supply device 13 of the embodiment, the movable guide 44 has a pressing part (second pressing part) 86 that presses the main body 3B of the component 3 away from the fixed guide 46 when it moves away from the component 3. With this structure, the component 3 pressed by the fixed guide 46 can be returned to its original position.

[0136] Furthermore, according to the component supply device 13 of the embodiment, the movable guide 44 also has another contact portion 60 that contacts the lead wire 3R of the component 3 at a spacing adjustment position P1 located upstream of the bending formation position P2. The other contact portion 60 has inclined portions 64A and 64B that are inclined in the direction of narrowing the spacing of the lead wire 3R of the component 3. With this structure, by adjusting the spacing of the lead wire 3R upstream of the bending formation position P2, it is easy to form a bend 3K of the same shape at the bending formation position P2.

[0137] Furthermore, the component supply device 13 of the embodiment includes a first drive source 34 for feeding the component 3 on the transport path TR, and a second drive source 48 for driving the movable guide 44 along the transverse direction B. With this structure, the feeding action of the component 3 and the reciprocating drive of the movable guide 44 can be performed independently.

[0138] Furthermore, the component supply device 13 in this embodiment also includes a control unit 16, which intermittently performs feeding operations on the component 3 based on the first drive source 34, and drives the movable guide 44 based on the second drive source 48 during periods when the feeding of the component 3 based on the first drive source 34 stops. With this structure, unnecessary interference of the movable guide 44 with the component 3 can be prevented.

[0139] Furthermore, the component mounting machine 1 of the embodiment includes a component supply device 13 having a bending forming mechanism 40 and a component assembly mechanism 15. The component assembly mechanism 15 picks up the component 3 at the pick-up position 13P in the component supply device 13 and inserts the lead 3R of the picked-up component 3 into the substrate 2 to assemble the component 3 onto the substrate 2. The component mounting machine 1 with this structure can achieve the same effect as the component supply device 13 having the bending forming mechanism 40.

[0140] Furthermore, the component supply method of the embodiment includes a conveying step of conveying the component 3 toward the pickup position 13P in the conveying path TR, and a bending forming step of forming a bend 3K in the lead wire 3R of the component 3 in the conveying path TR. In the bending forming step, a bending forming mechanism 40 is used, which has a movable guide 44 that can move in the transverse direction B that intersects the conveying direction A and a fixed guide 46 that is opposite to the movable guide 44 across the conveying path TR. The movable guide 44 is moved toward the component 3, and the inclined portions 66A and 66B provided on the movable guide 44 come into contact with the lead wire 3R of the component 3. A portion of the contacting lead wire 3R is bent outward to form a bend 3K.

[0141] According to this method, the same effect as the component supply device 13 in the embodiment can be achieved.

[0142] The present invention has been described above with examples of the embodiments described above, but the present invention is not limited to the embodiments described above. For example, in this embodiment, the case in which the spacing of the leads 3R is narrowed at the spacing adjustment position P1 and a portion of the leads 3R is bent outward at the bending formation position P2 to form a bend 3K is described, but the present invention is not limited to this case. For example, the spacing of the leads 3R may be widened at the spacing adjustment position P1 and a portion of the leads 3R may be bent inward at the bending formation position P2 to form a bend 3K. That is, the inclined portions 64A and 64B of the contact portion 60 may be inclined in the direction of widening or narrowing the spacing of the contacts of the leads 3R, and the inclined portions 66A and 66B of the contact portion 62 may be inclined in the direction of bending a portion of the contacts of the leads 3R outward or inward.

[0143] The invention has been fully described with reference to the accompanying drawings and in connection with preferred embodiments; however, various modifications and alterations will be apparent to those skilled in the art. Such modifications and alterations should be understood as being included as long as they do not depart from the scope of the invention based on the appended technical solutions. Furthermore, variations in the combination and order of elements in the various embodiments can be implemented without departing from the scope and spirit of the invention.

[0144] It should be noted that by appropriately combining any of the above-described embodiments and variations, the respective effects can be achieved.
