[0005] Patent Document 1: Japanese Patent No. 5864294 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, sometimes the orientation of the component at the pickup position deviates due to issues such as component precision. If the orientation of the component at the pickup position deviates, the component assembly mechanism will be unable to pick up the component properly, increasing the likelihood of errors. As a result, the component supply efficiency decreases.

[0012] Furthermore, the component mounting machine of the present invention includes: the component supply device; and a component assembly mechanism that picks up a component at the pick-up position in the component supply device and inserts the lead wire of the picked-up component into a substrate to assemble the component onto the substrate.

[0013] Additionally, the component supply method of the present invention includes: a conveying step of conveying a component toward a pickup position in a conveying direction; and an attitude correction step of correcting the attitude of a component located at the pickup position, the attitude correction step performing: a first limiting step of limiting lateral movement of the component at the pickup position that intersects the conveying direction; and a second limiting step of limiting movement of the component at the pickup position in the forward and backward direction along the conveying direction.

Detailed Implementation

[0079] 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 derived from the same technical concept are included in the present invention.

[0080] (Implementation Method 1)

[0081] Figure 1 The component mounting machine 1 according to Embodiment 1 of the present invention is shown. The component mounting machine 1 is an apparatus for assembling components 3 on 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. For ease of explanation, the left-right direction of the component mounting machine 1 as observed by 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.

[0082] exist Figure 1In this system, the substrate conveying mechanism 12 uses a pair of conveying mechanisms 12a to transport the substrate 2 along the X-axis direction and position the substrate 2 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.

[0083] exist Figure 1 In this process, each component supply device 13 has a component supply port 13K on its front end side, and a pickup position 13P directly below the component supply port 13K. Figure 2 The component 3 is continuously supplied by the component supply device 13. In embodiment 1, the component 3 supplied by the component supply device 13 is a radial component with leads (radial taping component), and as shown... Figure 3 The diagram shows a cylindrical trunk 3B and two leads 3R extending downward from the trunk 3B.

[0084] 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 has its field of view facing upwards and captures images of the component 3 picked up by the component assembly mechanism 15 from below.

[0085] exist Figure 1 In this assembly mechanism 15, a head moving mechanism 21 is mounted on a base 11, and an assembly head 22 is moved by the head moving mechanism 21. The head moving mechanism 21 includes a fixed platform 21a, a moving platform 21b, and a moving plate 21c. The fixed platform 21a is fixed to the base 11, and the moving platform 21b is movable along the fixed platform 21a in the Y-axis direction. The moving plate 21c is movable along the moving platform 21b in the X-axis direction, and the assembly head 22 is mounted on the moving plate 21c. The assembly head 22 is movable in the horizontal direction by the movement of the moving platform 21b and the moving plate 21c.

[0086] 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 by the vacuum source, thereby generating a vacuum suction force at the component suction port of each suction nozzle 22a.

[0087] After the head moving mechanism 21 moves the assembly head 22 above the component supply port 13K of the component supply device 13, the suction nozzle 22a descends and the lower end of the suction nozzle 22a contacts the main body 3B of the component 3 for vacuum suction. This allows the component 3 supplied to the pickup position 13P to be picked up. Figure 2 , Figure 3 ).

[0088] 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 causes the touch panel 101 to display content related to the operating status of the component mounting machine 1 and accepts input from the operator (OP).

[0089] exist Figure 2 In the middle, each component supply device 13 has a connection to the trolley 11D ( Figure 1 The base portion 31 and the cover portion 32 mounted on the base portion 31 are provided. A component holding belt 4 is provided on the base portion 31 in the area covered by the cover portion 32. The component holding belt 4 is a strip-shaped member that holds the lead wires 3R of a plurality of components 3, and travels along the Y-axis in the conveying direction A along the conveying path TR provided inside the cover portion 32.

[0090] like Figure 2 As shown, a first drive source 34 for maintaining the components at a 4-pitch distance is provided inside the component supply device 13. In this embodiment, the first drive source 34 is a working cylinder with 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.

[0091] 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.

[0092] Figure 2 The component supply device 13 shown is equipped with at least two component correction mechanisms 40 and 42, which serve as mechanisms for correcting the attitude, position, lead wire spacing, etc. of the component 3 conveyed on the conveying path TR. Figure 2 In the diagram, the locations of the component correction mechanisms 40 and 42 are indicated by dashed lines, and the specific structural diagrams are omitted.

[0093] The first component correction mechanism 40 is located at a position A1 upstream of the pickup position 13P in the conveying direction A, and the second component correction mechanism 42 is located at the pickup position 13P downstream of the first component correction mechanism 40 in the conveying direction A2.

[0094] By providing component correction mechanisms 40 and 42 in the component supply device 13, the posture and position of component 3 at pickup position 13P are stabilized, thereby improving the success rate of component assembly mechanism 15 in picking up component 3. Furthermore, by adjusting the lead spacing of component 3, the lead 3R of component 3 picked up by component assembly mechanism 15 can be inserted with good accuracy into the insertion hole of substrate 2. This improves the component supply efficiency of component supply device 13.

[0095] The following uses Figure 4 The following figures will illustrate the structure and operation of the component correction mechanisms 40 and 42.

[0096] (First component correction mechanism 40: Posture correction mechanism 40A)

[0097] Figure 4 , Figure 5 This is a perspective view and a top view of the first component correction mechanism 40 in Embodiment 1. The first component correction mechanism 40 in Embodiment 1 is an attitude correction mechanism 40A used to correct the attitude of the component 3 midway along the transport path TR. Hereinafter, the first component correction mechanism 40 will be described as the attitude correction mechanism 40A.

[0098] 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 mounted on the main body 43 of the device that forms the conveying path TR.

[0099] The movable guide 44 and the fixed guide 46 are components used to clamp the lead wire 3R of component 3 in the middle and correct the posture of the conveying direction A of component 3.

[0100] The movable guide 44 is a guide portion configured to move in a transverse direction B, which is intersecting the conveying direction A. In Embodiment 1, the transverse direction B is a horizontal direction orthogonal to the conveying direction A and corresponds to the X-axis direction. The fixed guide 46 is disposed opposite the movable guide 44 across the conveying path TR and is fixed to the main body 43 of the device.

[0101] 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 stopping at the first correction position P1, the component 3 is fed a distance and stops at the second correction position P2.

[0102] The movable guide 44 and the fixed guide 46 have the function of changing the tilt of component 3 in the first correction position P1 towards the forward side (downstream side A2), and also have the function of changing the tilt of component 3 in the second correction position P2 towards the rearward side (upstream side A1). By changing the tilt of component 3 towards both the forward and rearward sides, regardless of whether component 3 tilts forward or backward, it is possible to correct component 3 towards an upright posture while taking into account the springback of lead wire 3R. Details will be described later.

[0103] 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 serves as a drive source for the aforementioned first drive source 34 (…). Figure 2 The second drive source 48 of Embodiment 1 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.

[0104] The cam mechanism 50 is a mechanism for converting the driving force of the second drive source 48 along the conveying direction A 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 a protrusion 58 of the cam follower 56 is engaged in the cam groove 55. The cam groove 55 has an inclined shape when viewed from above, such that the cam follower 56 moves along the lateral direction 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 where it can move in the lateral direction B and its movement in the back and forth direction is restricted.

[0105] According to this structure, if 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 engaged with the cam 54 reciprocates in the transverse direction B. Thus, the movable guide 44 connected to the cam follower 56 can reciprocate in the transverse direction B. Figure 4 , Figure 5 In the example, the state (when in motion) of the fixed guide 46 closest to the movable guide 44 is shown.

[0106] Next, use Figures 6-9 The structures of the movable guide 44 and the fixed guide 46 are described.

[0107] Figure 6 , Figure 7 This is a perspective view showing the movable guide 44, the fixed guide 46, and the component retaining band 4. Figure 8 , Figure 9 Is with Figure 6 , Figure 7 The corresponding top views. Figure 6 , Figure 8 The image shows the movable guide 44 approaching the fixed guide 46. Figure 7 , Figure 9 The image exaggerates the state in which the movable guide 44 is far removed from the fixed guide 46. Figures 6-9 The illustrations of other components, including component 3, are omitted.

[0108] like Figure 7 , Figure 9 As shown, the movable guide 44 has two contact portions 60 and 62. Contact portions 60 and 62 are respectively used to contact the lead wire 3R of the component 3 located in the correction positions P1 and P2 and change the posture of the component 3. Contact portions 60 and 62 both have a shape that protrudes laterally B towards the fixed guide 46 in the movable guide 44.

[0109] Recesses 64 and 66 are formed at both ends of the fixed guide 46. Recesses 64 and 66 are recesses that receive one end of the contact portions 60 and 62 when they approach each other.

[0110] like Figure 7 , Figure 9 As shown, 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.

[0111] Inclined portions 60A and 62A are surfaces that are inclined relative to both the conveying direction A and the transverse direction B when viewed from above. Non-inclined portions 60B and 62B are surfaces that extend in the transverse direction B when viewed from above.

[0112] The first inclined portion 60A is the part that contacts the lead wire 3R of component 3 located at the first correction position P1 and changes the orientation of component 3 towards the forward side (downstream side A2). The first inclined portion 60A contacts the rear side (upstream side A1) of the two leads 3R of component 3. In Embodiment 1, the first inclined portion 60A has a conical shape that is inclined towards the downstream side A2 of the conveying direction A, moving further away from the fixed guide member 46.

[0113] The second inclined portion 62A is the part that contacts the lead wire 3R of the component 3 located at the second correction position P2 and changes the posture of the component 3 to the rearward side (upstream side A1). The second inclined portion 62A contacts the front side (downstream side A2) of the two leads 3R of the component 3. The second inclined portion 62A of Embodiment 1 has a conical shape that is inclined in a direction that is further away from the fixed guide member 46 as it moves towards the upstream side A1 of the conveying direction A.

[0114] The first non-inclined portion 60B is the portion that extends laterally B and connects to the first inclined portion 60A on the inner side of the first inclined portion 60A. The first non-inclined portion 60B abuts the lead wire 3R of the component 3 after it comes into contact with the first inclined portion 60A and restricts its movement upstream to the A1.

[0115] The second non-inclined portion 62B is the portion that extends laterally B and connects to the second inclined portion 62A on the inner side of the second inclined portion 62A. The second non-inclined portion 62B abuts the lead wire 3R of the component 3 after it comes into contact with the second inclined portion 62A and restricts its movement to the downstream side A2.

[0116] The movable guide 44 also has a connecting portion 68. The connecting portion 68 connects the first non-tilted portion 60B and the second non-tilted portion 62B, and extends along the conveying direction A. The connecting portion 68 is located in a position recessed inward relative to the first non-tilted portion 60B and the second non-tilted portion 62B, and is opposed to the fixed guide 46 in the transverse direction B. Together with the fixed guide 46, the connecting portion 68 restricts the movement of the lead wire 3R of the component 3 located at the correction positions P1 and P2 in the transverse direction B. In Embodiment 1, the connecting portion 68 has a length including both the first correction position P1 and the second correction position P2.

[0117] use Figures 10A to 10D as well as Figures 11A to 11D This describes a method for correcting the tilting of component 3 in the transport direction A using an attitude correction mechanism 40A with the above-described structure. Figures 10A to 10D This diagram illustrates the correction method when component 3 tilts backward. Figures 11A to 11D This diagram illustrates the correction method when component 3 tilts forward.

[0118] exist Figure 10A , Figure 10B In the example shown, component 3 (illustrated by dashed lines) delivered to the first correction position P1 is tilted rearward (upstream side A1) relative to its upright posture with respect to the vertical axis Q0. The central axis Q1 of component 3 is tilted rearward relative to the vertical axis Q0. If the second drive source 48 is driven in this state ( Figure 4 , Figure 5The movable guide 44 is driven laterally in the direction B, close to the fixed guide 46. The first inclined portion 60A of the first contact portion 60 then contacts the lead wire 3R on the rear side of the component 3 at the first correction position P1 (first contact step). The first inclined portion 60A tilts so that the closer it is to the downstream side A2 of the conveying direction A, the further it is from the fixed guide 46. As the movable guide 44 advances, the first inclined portion 60A presses the lead wire 3R against the fixed guide 46 while simultaneously applying force to the downstream side A2. As a result, the posture of the component 3 changes towards the forward side C1 (downstream side A2) (illustrated by solid lines).

[0119] like Figure 10A As shown, in the first correction position P1, the shape and position of the first tilting part 60A are set such that the central axis Q2 of component 3 is tilted forward relative to the vertical axis Q0. As will be described later, taking into account the springback generated by the lead wire 3R of component 3, the first tilting part 60A corrects the posture of component 3 to a position that is tilted forward than the upright posture.

[0120] The lead wire 3R of component 3 after contacting the first inclined part 60A and Figures 7-9 The first non-inclined portion 60B, located inside the first inclined portion 60A, makes contact. When the lead wire 3R of component 3 springs back and returns to the upstream side A1, the first non-inclined portion 60B blocks the lead wire 3R, thereby restricting its movement to the upstream side A1.

[0121] The lead wire 3R of component 3 is positioned in the area between the connecting portion 68 and the fixed guide 46, which is provided inside the first non-inclined portion 60B. As a result, the lateral movement B of the lead wire 3R is restricted.

[0122] exist Figure 10C , Figure 10D The text shows from Figure 10A , Figure 10B The state shown indicates that the movable guide 44 has retracted. (As shown) Figure 10C , Figure 10D As shown, when component 3, located in the first correction position P1, is tilted slightly forward relative to the vertical axis Q0 (illustrated by dashed lines), the contact with the first contact portion 60 is released, and a spring is generated at the lead wire 3R of component 3, so that the lead wire 3R naturally returns to the upstream side A1. The tilt of component 3 changes to the rearward side C3 (upstream side A1) (illustrated by solid lines).

[0123] In Embodiment 1, considering the springback of the lead wire 3R, the target posture for correcting the posture of the component 3 using the first tilting part 60A is set such that the component 3 after springback is in a generally upright posture and the central axis Q3 is approximately aligned with the vertical axis Q0.

[0124] After being corrected to an upright position at the first correction position P1, component 3 is fed along the conveying direction A (conveyance step) and stops at the second correction position P2. Figure 10A , Figure 10B Part 3 is shown stopping at the second correction position P2.

[0125] like Figure 10A , Figure 10B As shown, when component 3, stopped at the second correction position P2, is in a roughly upright posture (illustrated by dashed lines), if the movable guide 44 is driven towards the fixed guide 46 using the aforementioned second drive source 48, the second inclined portion 62A of the second contact portion 62 contacts the lead wire 3R on the front side of component 3 (second contact step). As a result, the posture of component 3 changes to the rearward side C2 (upstream side A1) (illustrated by solid lines).

[0126] Regarding the second correction position P2, taking into account the springback of the lead wire 3R of component 3, the target posture of component 3 after posture correction by the second tilting part 62A is set as the position where the central axis Q4 of component 3 is tilted to the rear side C2 compared to the vertical axis Q0.

[0127] Then, if the movable guide 44 is retracted, then as Figure 10C , Figure 10D As shown, when component 3 is tilted slightly backward relative to the vertical axis Q0 (illustrated by dashed lines), a springback occurs at the lead wire 3R of component 3, causing the tilt of component 3 to naturally change forward to the front side C4 (downstream side A2) (illustrated by solid lines). Similar to the first correction position P1, after the springback, component 3 becomes approximately upright, and the central axis Q5 of component 3 is approximately aligned with the vertical axis Q0.

[0128] As described above, component 3, which has been corrected to an upright posture at the first correction position P1, is also corrected to an upright posture again at the second correction position P2. In this way, when component 3, which has been fed to the first correction position P1, tilts to the rear side (upstream side A1), the posture correction mechanism 40A corrects the posture of component 3 in two stages, thereby correcting component 3 to an upright posture.

[0129] Next, use Figures 11A to 11D The posture correction method for component 3 when it tilts forward (downstream side B2) is explained.

[0130] exist Figure 11A , Figure 11B In the example shown, component 3 (illustrated by solid lines) delivered to the first correction position P1 is tilted forward (downstream side A2) relative to its upright posture with respect to the vertical axis Q0. The central axis Q6 of component 3 is tilted forward relative to the vertical axis Q0. If the second drive source 48 is driven in this state ( Figure 4 , Figure 5 ), and drive the movable guide 44 laterally in a manner close to the fixed guide 46, then as Figure 11A , Figure 11B As shown, when component 3 tilts significantly forward, the first inclined portion 60A of the first contact portion 60 does not contact the guide wire 3R on the rear side of component 3, and does not correct the posture of component 3 (arrow C1). In this case, even if the movable guide 44 is retracted, no rebound occurs on the guide wire 3R of component 3, therefore... Figure 11C , Figure 11D As shown, component 3 maintains a forward tilted position.

[0131] On the other hand, when the tilt of component 3 is small, when the movable guide 44 approaches the fixed guide 46, it is in harmony with... Figures 10A to 10D As shown, the first inclined part 60A contacts the lead wire 3R on the rear side of the component 3 and corrects the posture of the component 3 to the forward side C1.

[0132] Component 3, whose posture was not corrected at the first correction position P1, is fed to the second correction position P2. For example... Figure 11A , Figure 11B As shown, when component 3, which is stopped at the second correction position P2, tilts significantly forward (illustrated by dashed lines), if the movable guide 44 is driven towards the fixed guide 46 using the aforementioned second drive source 48, the second tilting portion 62A of the second contact portion 62 contacts the lead wire 3R on the front side of component 3. As a result, the posture of component 3 changes to the rearward side C5 (upstream side A1) (illustrated by solid lines).

[0133] and Figures 10A to 10D The situation is similar. After attitude correction by the second tilting part 62A, the target attitude of component 3 is determined by considering the springback of the guide wire 3R of component 3, and the central axis Q7 of component 3 is set to tilt rearward by C5 relative to the vertical axis Q0. Then, if the movable guide 44 is retracted, then... Figure 11C , Figure 11D As shown, the lead wire 3R of component 3 springs back, and the posture of component 3 naturally changes to the forward side C6 (downstream side A2) (illustrated by solid lines).

[0134] As described above, even if component 3 tilts forward, the attitude correction mechanism 40A can be used to correct component 3 towards an upright posture. In this case, when the tilt of component 3 is large, it is not corrected to an upright posture at the first correction position P1, but at the second correction position P2. When the tilt of component 3 is small, it is corrected to an upright posture at both the first correction position P1 and the second correction position P2. In this way, similar to the case where component 3 tilts backward, the posture of component 3 can be corrected towards an upright posture.

[0135] according to Figures 10A to 10D , Figures 11A to 11D The actions shown involve changing the orientation of component 3 forward at the first correction position P1 and changing its orientation backward at the second correction position P2. Therefore, regardless of whether component 3 is tilted forward or backward, it can be corrected to an upright posture.

[0136] Subsequently, the attitude correction of component 3, which stops sequentially at correction positions P1 and P2, is performed based on the attitude correction mechanism 40A. This allows the attitude of component 3 to be corrected midway to the pickup position 13P, stabilizing the attitude of component 3 upon arrival at pickup position 13P. Consequently, the success rate of component assembly mechanism 15 picking up component 3 at pickup position 13P is improved, and the supply efficiency of component supply device 13 for component 3 is increased.

[0137] (The function and effects related to the 40A posture correction mechanism)

[0138] As described above, the component supply device 13 of Embodiment 1 includes a transport path TR that transports the component 3 toward the pickup position 13P in the transport direction A, 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 having contact portions 60 and 62 that can contact the lead wire 3R of the component 3, and being movable in a transverse direction B intersecting the transport direction A; and a fixed guide 46 disposed at a position opposite to the movable guide 44 across the lead wire 3R of the component 3. The movable guide 44 has a first contact portion 60 that contacts the lead wire (first lead wire) 3R on the rear side of the component 3 and a second contact portion 62 that contacts the lead wire (second lead wire) 3R on the front side of the component 3. The first contact portion 60 has a first inclined portion 60A that is inclined to the forward side (downstream side A2) of the component 3, and the second contact portion 62 has a second inclined portion 62A that is inclined to the rear side (upstream side A1) of the component 3.

[0139] According to this structure, the orientation of component 3 can be changed to the forward and rearward sides respectively using the two tilting parts 60A and 62A, so that the orientation of component 3 can be corrected regardless of whether it is tilted forward or backward. As a result, the supply efficiency of component supply device 13 to component 3 can be improved.

[0140] Furthermore, according to the component supply device 13 of Embodiment 1, the first inclined portion 60A has a shape that is inclined towards the downstream side A2 of the conveying direction A, moving further away from the fixed guide 46, and the second inclined portion 62A has a shape that is inclined towards the upstream side A1 of the conveying direction A, moving further away from the fixed guide 46. With this structure, the posture of the component 3 can be changed towards the desired target posture using the two inclined portions 60A and 62A.

[0141] Furthermore, according to the component supply device 13 of Embodiment 1, the first contact portion 60 also has a first non-inclined portion 60B extending along the transverse direction B inside the first inclined portion 60A. Additionally, the second contact portion 62 also has a second non-inclined portion 62B extending along the transverse direction B inside the second inclined portion 62A. With this structure, the movement of the lead wire 3R of the component 3 in the transport direction A after contact with the inclined portions 60A and 62A can be restricted by the non-inclined portions 60B and 62B, and the posture of the component 3 can be accurately corrected.

[0142] Furthermore, according to the component supply device 13 of Embodiment 1, the attitude correction mechanism 40A has a connecting portion 68 that extends along the transport direction A in a manner that connects the first non-tilting portion 60B and the second non-tilting portion 62B. With this structure, the lead wire 3R of the component 3 can be clamped between the connecting portion 68 and the fixed guide 46 and its movement in the lateral direction B can be restricted, and the tilting of the component 3 in the transport direction A can be corrected with good precision.

[0143] Furthermore, according to the component supply device 13 of Embodiment 1, the first contact portion 60 is located at a position A1 upstream of the second contact portion 62 in the conveying direction A. With this structure, the two inclined portions 60A and 62A are formed inward, which enables miniaturization of the movable guide 44.

[0144] Furthermore, the component supply device 13 in Embodiment 1 also includes a control unit 16. The control unit 16 controls the first drive source 34 to perform intermittent feeding operations on the components 3, and stops each component 3 at both the first correction position P1 where the first contact portion 60 contacts the rear-side lead wire (first lead wire) 3R and the second correction position P2 where the second contact portion 62 contacts the front-side lead wire (second lead wire) 3R. With this structure, both corrections that change the posture of each component 3 to the forward side and corrections that change the posture of each component 3 to the rear side can be performed, and the posture of the component 3 can be corrected regardless of whether the component 3 is tilted forward or backward.

[0145] Furthermore, the component supply device 13 of Embodiment 1 includes a first drive source 34 for feeding the component 3 in the transport path TR and a second drive source 48 for driving the movable guide 44 in 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 executed independently.

[0146] Furthermore, according to the component supply device 13 of Embodiment 1, the component 3 is fed intermittently based on the first drive source 34, and the movable guide 44 is driven by the second drive source 48 during the period when the feeding of the component 3 based on the first drive source 34 stops. With this structure, interference of the movable guide 44 with the component 3 can be prevented.

[0147] Furthermore, the component mounting machine 1 of Embodiment 1 includes: a component supply device 13 having an attitude correction mechanism 40A; and a component assembly mechanism 15. The component assembly mechanism 15 picks up a component 3 from 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 attitude correction mechanism 40A.

[0148] Furthermore, the component supply method of Embodiment 1 includes: a conveying step, in which the component 3 is conveyed toward the pickup position 13P in the conveying direction A; and an attitude correction step, in which the attitude of the component 3 is corrected. The attitude correction step uses an attitude correction mechanism 40A equipped with a movable guide 44 and a fixed guide 46 to perform a first contact step and a second contact step. In the first contact step, the first contact portion 60 of the movable guide 44 contacts the lead wire 3R (first lead wire) on the rear side of the component 3, and the component 3 is tilted forward (downstream side A2) by the first tilting portion 60A provided on the first contact portion 60. In the second contact step, the second contact portion 62 of the movable guide 44 contacts the lead wire 3R (second lead wire) on the front side of the component 3, and the component 3 is tilted backward by the second tilting portion 62A provided on the second contact portion 62.

[0149] According to this method, the orientation of component 3 can be changed to the forward and rearward sides respectively, so that the orientation of component 3 can be corrected regardless of whether it is tilted forward or backward. As a result, the supply efficiency of component 3 can be improved.

[0150] (Modifications related to posture correction mechanism 40A)

[0151] In Embodiment 1, the case where a set of movable guides 44 and fixed guides 46 are provided is described, but this is not limited to this case. For example, two or more sets of movable guides 44 and fixed guides 46 may be provided at intervals along the conveying direction A. In Embodiment 1, the case where the posture of the component 3 after springback correction at both the first correction position P1 and the second correction position P2 is described as being approximately upright is described, but this is not limited to this case. For example, the component 3 may be corrected to an upright posture by significantly tilting forward at the first correction position P1 and slightly tilting backward at the second correction position P2. That is, the correction may be performed in a manner that does not bring the posture of the component 3 close to an upright posture at the first correction position P1. In this case, another set of movable guides 44 and fixed guides 46 may be provided on the downstream side B2, and in the other set, the component may be significantly tilted backward at the first correction position and slightly tilted forward at the second correction position. Therefore, regardless of whether component 3 is tilted forward or backward, by setting two sets of movable guides 44 and fixed guides 46 to correct the tilt of component 3, the posture of component 3 can be made close to an upright posture.

[0152] Furthermore, in Embodiment 1, the case where a movable guide 44 integrally forms the first contact portion 60 and the second contact portion 62 was described, but this is not limited to this case, and they can also be configured separately. That is, it is also possible to provide a first movable guide with the first contact portion 60 and a second movable guide with the second contact portion 62.

[0153] (Second component correction mechanism 42)

[0154] Next, use Figures 12-24B For Figure 2 The second component correction mechanism 42, which is provided at the pickup position 13P of the component supply device 13 shown, will be described.

[0155] Figure 12 , Figure 13 This is a perspective view of the second component correction mechanism 42 in embodiment 1. Figure 14This is a top view of the second component correction mechanism 42. The second component correction mechanism 42 in Embodiment 1 is an attitude correction mechanism 42A for correcting the attitude of the component 3 located at the pickup position 13P. Hereinafter, the second component correction mechanism 42 will be described as attitude correction mechanism 42A.

[0156] As described above, the attitude correction mechanism 40A is used to temporarily correct the attitude of the component 3 on the upstream side A1 of the pickup position 13P. The component supply device 13 of Embodiment 1 is also provided with an attitude correction mechanism 42A at the pickup position 13P in order to maintain the component 3 at the pickup position 13P in an upright posture with better accuracy.

[0157] As will be described later, in the component supply device 13 of Embodiment 1, the orientation of the component 3 at the pick-up position 13P is easily distorted because the lead wire 3R is cut when the component 3 is at the pick-up position 13P. Therefore, in the component supply device 13 of this embodiment, an orientation correction mechanism 42A is provided at the pick-up position 13P to perform the lead wire 3R cutting operation while maintaining the component 3 in an upright position. This ensures that the orientation of the component 3 remains stable even after the cutting operation.

[0158] Figures 12-14 The attitude correction mechanism 42A shown includes a first limiting part 100, a second limiting part 102, a first drive source 34, a cam mechanism 106, and a lead wire cutting part 107. The first limiting part 100, the second limiting part 102, the first drive source 34, the cam mechanism 106, and the lead wire cutting part 107 are all mounted on the main body 43 of the device that forms the transport path TR.

[0159] The first limiting part 100 and the second limiting part 102 are components used to limit the movement of the component 3 located at the pick-up position 13P and to maintain the posture of the component 3 in an upright position. The specific structure of the first limiting part 100 and the second limiting part 102 will be described later, but the first limiting part 100 has the function of limiting the lateral movement B of the component 3, and the second limiting part 102 has the function of limiting the movement of the component 3 in the forward and backward direction along the conveying direction A.

[0160] By providing the first limiting part 100 and the second limiting part 102, the horizontal movement (XY axis direction) of the component 3 is restricted, and the component 3 located at the pickup position 13P can be held in an upright position with good accuracy. As a result, the lead wire 3R can be cut while maintaining the posture of the component 3.

[0161] In the attitude correction mechanism 42A of Embodiment 1, the first limiting part 100 is fixed to the main body part 43, and the second limiting part 102 is mounted to the main body part 43 in a manner that allows it to move laterally B. The second limiting part 102 is driven by a first drive source 34 for performing the feeding action of the component 3. Figure 12 )drive.

[0162] The first driving source 34 is used to... Figure 2 The component shown retains a drive source with a 4-pitch feed and also serves as a drive source for driving the second limiting part 102 in the transverse direction B. The output shaft 35 of the first drive source 34 is connected to the cam mechanism 106.

[0163] The cam mechanism 106 is a mechanism for converting the driving force of the first drive source 34 along the conveying direction A into a driving force in the lateral direction B and transmitting it to the second limiting part 102. The cam mechanism 106 includes a cam 108 connected to the output shaft 35 and a cam follower 110 engaged with the cam 108 and connected to the second limiting part 102. A cam groove 109 is formed in the cam 108, and a protrusion 111 of the cam follower 110 is engaged in the cam groove 109. The cam groove 109 has an inclined shape when viewed from above, such that the cam follower 110 moves in the lateral direction B when the cam 108 moves back and forth along the conveying direction A. The cam follower 110 is mounted on the main body 43 of the device in a state where it can move in the lateral direction B and its movement in the back and forth direction is restricted.

[0164] According to this structure, if the first drive 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 transverse direction B. This allows the second limiting part 102 connected to the cam follower 110 to reciprocate in the transverse direction B. The second limiting part 102 reciprocates between a limiting position for the movement of the limiting member 3 and a retracted position from the member 3. Figures 12-14 The example shows the second limiting part 102 in the limiting position (when in operation).

[0165] The lead wire cutting section 107 is a component that cuts the lead wire 3R of the component 3 located at the pickup position 13P. By cutting the lead wire 3R of the component 3 at the pickup position 13P, the length of the lead wire 3R is pre-adjusted to the desired length.

[0166] The lead wire cutting section 107 has a fixed section 107A and a movable section 107B. The fixed section 107A is a member fixed to the main body section 43 of the device, and the movable section 107B is a member configured to reciprocate in the lateral direction B by a drive source (not shown). The fixed section 107A and the movable section 107B each have a cutting edge (not shown) for cutting the lead wire 3R of the member 3. The lead wire 3R of the member 3 is cut by clamping the cutting edges of the member 3 between the movable section 107B and the fixed section 107A when the movable section 107B approaches the fixed section 107A.

[0167] like Figures 12-14 As shown, a conveyor chute 112 is provided on the downstream side A2 of the pickup position 13P. The conveyor chute 112 is a component used to further feed the component holding belt 4 downstream from the pickup position 13P. Since the component 3 is picked up at the pickup position 13P, the component holding belt 4 conveyed to the conveyor chute 112 does not normally hold the component 3. Exceptions include situations where the operator manually feeds the component holding belt 4 downstream to A2 while the component supply device 13 is stopped, in which case the component holding belt 4 conveyed by the conveyor chute 112 may sometimes hold the component 3.

[0168] Next, use Figures 15-17 The specific structures of the first restriction section 100 and the second restriction section 102 will be explained.

[0169] Figure 15 This is a perspective view showing the peripheral structure of the first limiting part 100 and the second limiting part 102. Figure 16 , Figure 17 This is a side view showing the surrounding structure.

[0170] like Figure 15 As shown, the first limiting part 100 includes a first horizontal guide 113 and a second horizontal guide 114. The horizontal guides 113 and 114 are members that clamp the component 3 located at the pick-up position 13P in the horizontal direction B and restrict its movement. The first horizontal guide 113 is disposed on the right side facing the conveying direction A, and the second horizontal guide 114 is disposed on the left side facing the conveying direction A. Both horizontal guides 113 and 114 are plate-shaped members extending along the conveying direction A and are fixed to the side of the conveying path TR to avoid interfering with the feeding action of the component 3.

[0171] The second limiting part 102 includes a front guide part 116 and a rear guide part 118. The guide parts 116 and 118 are members that clamp the component 3 located at the pickup position 13P in the front-back direction and restrict its movement. The front guide part 116 is disposed in front of the pickup position 13P (downstream side A2), and the rear guide part 118 is disposed behind the pickup position 13P (upstream side A1).

[0172] Both the front guide portion 116 and the rear guide portion 118 are connected to the aforementioned cam follower 110 and move integrally along the transverse direction B. Figures 15-17 In, with Figures 12-14 Similarly, the example shows the front guide 116 and the rear guide 118 in a restricted position that limits the movement of the restricting member 3.

[0173] The front guide portion 116 of Embodiment 1 has an L-shaped form when viewed from above. The front guide portion 116 extends downstream of the conveying direction A to the side A2 and then bends at approximately a right angle, and extends along the transverse direction B. The front end portion of the front guide portion 116 extending along the transverse direction B is configured to block the front of the member 3, thereby restricting the movement of the member 3 downstream of the side A2.

[0174] The rear guide portion 118 of Embodiment 1 has a so-called "hinge" structure. The rear guide portion 118 includes a fixing portion 120, a rotating portion 122, and a pressing portion 124.

[0175] The fixed part 120 is a plate-shaped member fixed to the cam follower 110. The rotating part 122 is a plate-shaped member connected to the fixed part 120 and configured to rotate about the rotation axis X1. The rotating part 122 rotates about the rotation axis X1 when it comes into contact with the component 3 that is moving along the conveying direction A, thereby preventing interference with the component 3.

[0176] The pressing part 124 is a force-applying member that applies force in the opposite direction to the rotational force that causes the rotating part 122 to rotate forward (downstream side A2). By providing the pressing part 124, the rotating part 122 is prevented from rotating violently forward due to contact with the component 3, and the operation of the rotating part 122 can be stabilized.

[0177] Here, using Figure 18A , Figure 18B The functions and operations of the rear guide section 118 are explained. Figure 18A This is a side view showing the state where component 3 is not in contact with the rotating part 122. Figure 18B This is a side view showing the state in which component 3 abuts against the rotating part 122 and the rotating part 122 has rotated.

[0178] like Figure 18AAs shown, the rotating part 122 is in a vertically downward position when it is not in contact with the component 3. At this time, the front end 110A of the cam follower 110 abuts against the root portion of the rotating part 122, thereby restricting the movement of the rotating part 122 so that it cannot rotate upstream to the A1 side (arrow R1). When the rotating part 122 is able to rotate downstream to the A2 side (arrow R2), the pressing part 124 abuts against the rotating part 122 and applies force in the opposite direction (arrow R3), thus generating resistance when the rotating part 122 rotates.

[0179] like Figure 18B As shown, if component 3 is conveyed in the conveying direction A and comes into contact with the rotating part 122, the rotating part 122 rotates downstream to the A2 about the rotation axis X1 (arrow R2) by contacting the side of component 3. By rotating the rotating part 122, interference with component 3 can be prevented.

[0180] When the rotating part 122 rotates, because the pressing part 124 applies force to the rotating part 122 in the opposite direction (arrow R3), the rotating part 122 does not rotate violently, but rotates slowly while maintaining contact with the side of the component 3. Therefore, the rotating part 122 will not collide with anything. Figure 18B The component 3 in front of the component 3 shown (not shown) rotates only within the necessary range, and the operation of the rotating part 122 is stable.

[0181] use Figure 19 The following figures illustrate the operation of the posture correction mechanism 42A having the above-described structure.

[0182] Figure 19 This is a top view showing the second limiting part 102 being reciprocated in the transverse direction B using a first drive source 34 having an output shaft 35. Figure 19 In the above, (a) corresponds to the state in which the second limiting part 102 is in the limiting position, and (b) corresponds to the state in which the second limiting part 102 is in the retreating position.

[0183] like Figure 19 As shown in (a), if the first drive source 34 drives the output shaft 35 to move the cam 108 of the cam mechanism 106 downstream to side A2, the protrusion 111 of the cam follower 110 moves laterally to side B along the cam groove 109, thereby moving the cam follower 110 to the left of the paper. The second limiting part 102 connected to the cam follower 110 also moves toward the left of the paper and toward the limiting position of the component 3 that limits the movement of the pickup position 13P.

[0184] like Figure 19As shown in (b), if the first drive source 34 drives the output shaft 35 to move the cam 108 of the cam mechanism 106 upstream to side A1, the protrusion 111 of the cam follower 110 moves laterally to side B along the cam groove 109, thereby moving the cam follower 110 toward the right side of the paper. The second limiting part 102 connected to the cam follower 110 also moves toward the right side of the paper and toward the retraction position of the component 3 retracting from the pickup position 13P.

[0185] The first drive source 34 drives the output shaft 35 in the front-rear direction at a predetermined cycle, thereby alternately switching between the state shown in (a) and the state shown in (b). The second limiting part 102 reciprocates between the limiting position and the retracting position, selectively limiting the front-rear movement of the component 3.

[0186] In Embodiment 1, a common first drive source 34 is used to drive the pitch feed of component 3 and the second limiting part 102. Therefore, a rotating part 122 is provided in the rear guide part 118 to prevent interference between the feed action of component 3 and the rear guide part 118, thereby enabling the simultaneous execution of the pitch feed of component 3 and the drive of the second limiting part 102.

[0187] Here, using Figure 20 The structure related to the feed action of component 3 will be described. Figure 20 This is a schematic side view showing the component retaining belt 4 and the plurality of components 3 held by the component retaining belt 4.

[0188] like Figure 20 As shown, the component retaining belt 4 has multiple feed holes 126 for pitched feeding. The feed holes 126 engage with a claw (not shown) connected to the first drive source 34.

[0189] When the first drive source 34 drives the claw downstream to side A2, the component holding belt 4 advances at a certain interval while the claw is engaged with the feed hole 126. On the other hand, when the first drive source 34 drives the claw upstream to side A1, the engagement between the claw and the feed hole 126 is released, so the component holding belt 4 remains stationary instead of retracting. By reciprocating the claw at a predetermined cycle by the first drive source 34, the component holding belt 4 is fed at intervals along the conveying direction A, and the feeding action of component 3 is performed intermittently.

[0190] In embodiment 1, large radial components are specifically treated as component 3. For example... Figure 20As shown, the spacing Y2 of component 3 is set to be longer (twice as in embodiment 1) relative to the spacing Y1 of feed hole 126. If the first drive source 34 performs two reciprocating drives, component holding belt 4 is fed downstream to A2 with two spacing amounts (Y1×2) of feed hole 126, and component 3 is fed downstream to A2 with one spacing amount (Y2).

[0191] When the first drive source 34 drives two reciprocating movements, the component 3 is fed by one pitch. In response, the reciprocating movement of the second limiting part 102, which is based on the same first drive source 34, is two reciprocations in the lateral direction B. That is, when the component 3 is fed by 0.5 pitch, the second limiting part 102 performs one reciprocation in the lateral direction B, so that the rear guide part 118 of the second limiting part 102 contacts the component 3 located in front of the pickup position 13P.

[0192] Therefore, in Embodiment 1, the posture correction mechanism 42A has the aforementioned rotating part 122 provided in the rear guide part 118, and the rotating part 122 can rotate when it comes into contact with the side of the component 3 located in front of the pickup position 13P. As a result, when the same first drive source 34 is used to perform the feeding action of the component 3 and the reciprocating action of the second limiting part 102, interference between the component 3 and the second limiting part 102 can be prevented, and the two actions can be performed simultaneously.

[0193] use Figures 21A to 24B The specific operation of the posture correction mechanism 42A with the above structure will be explained.

[0194] Figure 21A , Figure 21B This is a side view or perspective view showing the state of component 3 after it has been picked up at pickup position 13P.

[0195] like Figure 21A , Figure 21B As shown, the first limiting unit 100 has already limited the lateral movement B of the component 3 from the position behind the pickup position 13P. On the other hand, the second limiting unit 102 is in the retracted position and does not limit the movement of the component 3.

[0196] If from Figure 21A , Figure 21B From the state shown, the first drive source 34 drives the output shaft 35 forward (downstream side A2), thus becoming Figure 22A , Figure 22B The state shown.

[0197] like Figure 22A , Figure 22B As shown, component 3 is fed downstream to side A2 at 0.5 intervals (conveying step), and the second limiting part 102 moves laterally to side B in a manner close to the conveying path TR.

[0198] Component 3 is located in front of the pickup position 13P, so if the rotating part 122 of the second limiting part 102 moves laterally B, it will contact the side of component 3. Due to the contact with component 3, the rotating part 122 rotates towards the downstream side A2. Figure 22A (arrow R2). This prevents interference between the rear guide portion 118 and the component 3. At this time, the rotating portion 122 rotates while being pressed by the pressing portion 124 to the opposite side, so it does not rotate violently to the downstream side A2, but rotates slowly while maintaining contact with the side of the component 3. This makes the rotation of the rotating portion 122 stable.

[0199] Thus, even when the component 3 moves forward at a distance of 0.5 intervals due to the reciprocating drive of the first drive source 34, interference between the rear guide 118 and the component 3 can be prevented, and the feeding action of the component 3 and the reciprocating action of the second limiting part 102 can be performed simultaneously.

[0200] If from Figure 22A , Figure 22B From the state shown, the first drive source 34 drives the output shaft 35 to the rearward side (upstream side A1), thus becoming Figure 23A , Figure 23B The state shown.

[0201] like Figure 23A , Figure 23B As shown, component 3 remains stationary and does not move, while the second limiting part 102 moves laterally B away from the transport path TR and moves towards the retracted position. The rotating part 122, having been released from contact with component 3, returns to its vertically downward extending state.

[0202] If from Figure 23A , Figure 23B From the state shown, the first drive source 34 drives the output shaft 35 forward (downstream side A2), thus becoming Figure 24A , Figure 24B The state shown.

[0203] like Figure 24A , Figure 24B As shown, component 3 is fed downstream to A2 at a 0.5-pitch interval and reaches pickup position 13P. As the second limiting part 102 moves laterally to B near the transport path TR, component 3 moves towards pickup position 13P, so the rotating part 122 does not contact component 3. The rotating part 122 enters the area between component 3 at pickup position 13P and the component 3 in front of it.

[0204] If used Figure 18AAs explained, the rotation of the rotating part 122 is restricted to the upstream side A1 by the front end 110A of the cam follower 110, thereby restricting the movement of the component 3 to the upstream side A1. As a result, the component 3 located at the pickup position 13P is restricted from moving in the front and rear directions by being sandwiched between the front guide part 116 and the rear guide part 118.

[0205] exist Figure 24A , Figure 24B In the shown state, the first limiting part 100 restricts the lateral movement B of the component 3 at the pickup position 13P (first limiting step), and the second limiting part 102 restricts the movement of the component 3 at the pickup position 13P in the forward and backward direction along the conveying direction A (second limiting step). Thus, the horizontal movement of the component 3 can be restricted, while maintaining the component 3 in an upright position with good accuracy.

[0206] Then, the lead wire 3R is cut by the lead wire cutting part 107 on the component 3 located at the pickup position 13P. Specifically, the movable part 107B approaches the fixed part 107A and clamps the lead wire 3R of the component 3 between them, thereby cutting the lead wire 3R.

[0207] The lead wire cutting section 107 performs the cutting action on the lead wire 3R while the horizontal movement of the component 3 is restricted by the first limiting section 100 and the second limiting section 102. As a result, it is possible to suppress the distortion of the component 3's posture caused by the cutting action of the lead wire 3R and to maintain the upright posture of the component 3 with good accuracy.

[0208] The component 3 whose lead 3R has been cut was Figure 1 The component assembly mechanism 15 shown picks up the component. The component assembly mechanism 15 lowers the assembly head 22 located above the pick-up position 13P and brings the suction nozzle 22a of the assembly head 22 into contact with the upper surface of the main body 3B of the component 3 to suction the component 3. As a result, the component 3 at the pick-up position 13P is picked up, and the component supply device 13 supplies the component 3.

[0209] After picking up component 3, component assembly mechanism 15 inserts the lead 3R of component 3 into the insertion hole of substrate 2 and assembles it on substrate 2.

[0210] (The function and effect of posture correction mechanism 42A)

[0211] As described above, the component supply device 13 of Embodiment 1 includes: a transport path TR that transports the component 3 toward the pickup position 13P in the transport direction A; a first drive source 34 for performing a feeding action on the component 3 on the transport path TR; and an attitude correction mechanism 42A that corrects the attitude of the component 3 located at the pickup position 13P. The attitude correction mechanism 42A includes: a first limiting part 100 that limits the lateral movement B of the component 3 at the pickup position 13P that intersects the transport direction A; and a second limiting part 102 that limits the movement of the component 3 at the pickup position 13P in the forward and backward direction along the transport direction A.

[0212] Based on this structure, the attitude correction mechanism 42A is used to correct the attitude of the component 3 at the pickup position 13P, thereby improving the pickup success rate of the component 3. This, in turn, improves the supply efficiency of the component supply device 13 in supplying the component 3.

[0213] Furthermore, according to the component supply device 13 of Embodiment 1, the second limiting part 102 includes a front guide part 116 located on the downstream side A2 of the pickup position 13P and a rear guide part 118 located on the upstream side A1 of the pickup position 13P. With this structure, by providing the guide parts 116 and 118 on the front and rear of the component 3 located at the pickup position 13P, the movement in the front-rear direction can be limited with good precision.

[0214] Furthermore, according to the component supply device 13 of Embodiment 1, the second limiting part 102 is configured to move along the lateral direction B, thereby reciprocating between a limiting position and a retracting position that restricts the movement of the component 3 at the pick-up position 13P. With this configuration, by making the second limiting part 102 movable, the movement limiting action of the component 3 performed by the second limiting part 102 can be executed simultaneously with the feeding action of the component 3.

[0215] Furthermore, according to the component supply device 13 of Embodiment 1, the rear guide portion 118 has a rotating portion 122 configured to rotate in response to contact with the side of the component 3 when it moves toward the component 3 located in front of the pickup position 13P. With this structure, even when in contact with the component 3 located in front of the pickup position 13P, interference with the component 3 can be prevented by rotating the rotating portion 122 of the rear guide portion 118.

[0216] Furthermore, according to the component supply device 13 of Embodiment 1, the second limiting part 102 is connected to the first drive source 34 and is driven in the transverse direction B along with the feeding action of the component 3 performed by the first drive source 34. With this structure, the feeding action of the component 3 and the movement action of the second limiting part 102 can be performed using the shared first drive source 34.

[0217] Furthermore, according to the component supply device 13 of Embodiment 1, the attitude correction mechanism 42A also includes a cam mechanism 106 that converts the forward and backward driving force of the first drive source 34 into a lateral driving force B and transmits it to the second limiting part 102. With this structure, a simple mechanism can be used to convert the driving force of the first drive source 34 while simultaneously transmitting it to the second limiting part 102.

[0218] Furthermore, according to the component supply device 13 of Embodiment 1, the component 3 is a radially tapered component, and the conveying path TR carries the component holding belt 4, which holds multiple components 3, in the conveying direction A. With this structure, the radial component, especially in cases of poor component accuracy, is prone to deviation in the conveying direction A due to tilting. By using the second limiting part 102 to restrict movement in the forward and backward directions, the posture correction effect is significantly achieved.

[0219] Furthermore, according to the component supply device 13 of Embodiment 1, the first limiting part 100 includes a first horizontal guide 113 located on one side of the component 3 in the horizontal direction B relative to the pickup position 13P, and a second horizontal guide 114 located on the other side of the component 3 in the horizontal direction B relative to the pickup position 13P. With this structure, the horizontal movement of the component 3 in the horizontal direction B can be limited using a simple mechanism.

[0220] Furthermore, the component supply device 13 of Embodiment 1 also includes a lead cutting section 107 for cutting the lead wire 3R of the component 3 located at the pickup position 13P. With this structure, even when the lead wire 3R of the component 3 is cut at the pickup position 13P, since the cutting operation can be performed while the horizontal movement of the component 3 is restricted by the first limiting section 100 and the second limiting section 102, the orientation of the component 3 can be maintained with good accuracy after the lead wire is cut.

[0221] Furthermore, the component mounting machine 1 of Embodiment 1 includes: a component supply device 13 having an attitude correction mechanism 42A; and a component assembly mechanism 15. The component assembly mechanism 15 picks up a component 3 from 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 attitude correction mechanism 42A.

[0222] Additionally, the component supply method of Embodiment 1 includes: a conveying step, in which the component 3 is conveyed toward the pickup position 13P in the conveying direction A; and an attitude correction step, in which the attitude of the component 3 located at the pickup position 13P is corrected. In the attitude correction step, a first limiting step is performed to restrict the movement of the component 3 at the pickup position 13P in the lateral direction B intersecting the conveying direction A, and a second limiting step is performed to restrict the movement of the component 3 at the pickup position 13P in the forward and backward direction along the conveying direction A.

[0223] According to this method, by correcting the posture of component 3 at pickup position 13P, the pickup success rate of component 3 can be improved, and the supply efficiency of component 3 can be improved.

[0224] (Modifications related to posture correction mechanism 42A)

[0225] In implementation method 1, such as Figure 20 As shown, the distance Y1 between the feed holes 126 of the component holding belt 4 is twice the distance Y2 between the components 3, and the component 3 is fed one distance when the first drive source 34 performs two reciprocating drives. However, this is not limited to this case. The relationship between the distance Y1 between the feed holes 126 and the distance Y2 between the components 3 can be appropriately changed when the first drive source 34 performs one reciprocating drive to feed the component 3 one distance, or when it performs three or more reciprocating drives. Even in this case, according to the attitude correction mechanism 42A of Embodiment 1, since the second limiting part 102 also performs one reciprocating movement when the first drive source 34 performs one reciprocating drive, the movement of the component 3 reaching the pickup position 13P can be limited each time. Furthermore, since a rotating part 122 is provided in the rear guide part 118, interference with the component 3 located in front of the pickup position 13P can also be prevented.

[0226] (Implementation Method 2)

[0227] The component supply device according to Embodiment 2 of the present invention will be described. It should be noted that in Embodiment 2, the description mainly focuses on the differences from Embodiment 1, and the descriptions that are repeated in Embodiment 1 are omitted.

[0228] In embodiment 1, as the first component correction mechanism 40, an attitude correction mechanism 40A is provided with the attitude of the correction component 3. Figures 4 to 11D However, in Embodiment 2, a lead spacing adjustment mechanism 40B is provided as the first component correction mechanism 40 to adjust the spacing between the two leads 3R of the adjustment component 3. Hereinafter, the first component correction mechanism 40 will be described as the lead spacing adjustment mechanism 40B.

[0229] Figure 25 , Figure 26 These are, respectively, a perspective view and a top view of the lead wire spacing adjustment mechanism 40B in Embodiment 2.

[0230] The lead wire spacing adjustment mechanism 40B includes a movable guide 200, a fixed guide 202, a limiter 204, a second drive source 206, and a cam mechanism 208. The movable guide 200, the fixed guide 202, the limiter 204, the second drive source 206, and the cam mechanism 208 are all mounted on the main body 43 of the device that forms the conveying path TR.

[0231] The movable guide 200 is a guide portion configured to move laterally in the B direction. The movable guide 200 has the function of changing the spacing of the two leads 3R by contacting the two leads 3R of the component 3, which is stopped at a predetermined spacing adjustment position P3 in the transport path TR. It should be noted that... Figure 25 The following example illustrates the case where the main body 3B of component 3 is rectangular.

[0232] The fixed guide 202 is a guide part disposed opposite the movable guide 200 across the conveying path TR, and is fixed to the main body 43 of the device. The fixed guide 202 is disposed opposite the main body 3B and the lead wire 3R of the component 3 located at the pitch adjustment position P3, and has the function of maintaining the posture of the component 3 when the movable guide 200 contacts the lead wire 3R of the component 3.

[0233] The limiter 204 is a component used to maintain the posture of the component 3, which is located at the pitch adjustment position P3, together with the fixed guide 202. The limiter 204 is positioned opposite the fixed guide 202 across the conveying path TR and is fixed to the main body 43 of the device. If the main body 3B of the component 3 is arranged between the limiter 204 and the fixed guide 202, the lateral movement B of the main body 3B is restricted.

[0234] The movable guide 200 and the limiter 204 are positioned at different heights relative to the conveying path TR, on the same side. The movable guide 200 is positioned at the same height as the lead wire 3R of component 3, and the limiter 204 is positioned at the same height as the main trunk 3B of component 3. The fixed guide 202 is positioned at a height that overlaps with both the lead wire 3R and the main trunk 3B of component 3.

[0235] 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 serves as a drive source for the aforementioned first drive source 34 ( Figure 2 Different drive sources are provided, and an output shaft 207 capable of being driven along the conveying direction A is provided. In Embodiment 2, the second drive source 206 is a working 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.

[0236] The cam mechanism 208 is a mechanism for converting the driving force of the second drive source 206 along the conveying direction A into a lateral driving force 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 front end of the cam 210, and a protrusion 213 of the cam follower 212 engages with the cam groove 211. The cam groove 211 has a top-view inclined shape such that when the cam 210 moves back and forth along the conveying direction A, the cam follower 212 moves along the lateral direction B. The cam follower 212 is mounted on the main body 43 of the device in a state where it can move in the lateral direction B but its movement in the back-and-forth direction is restricted.

[0237] According to this structure, if the second drive source 206 drives the output shaft 207 back and forth along the conveying direction A, the cam 210 moves back and forth, and the cam follower 212 engaged with the cam 210 reciprocates in the transverse direction B. Thus, the movable part 200 connected to the cam follower 212 can reciprocate in the transverse direction B. Figure 25 , Figure 26 The image shows the state in which the movable guide 200 is closest to the fixed guide 202.

[0238] Next, use Figures 27-34 The structures of the movable guide 200, the fixed guide 202, and the limiter 204 are described.

[0239] Figure 27 , Figure 28 The images show a top view and a perspective view of the movable guide 200, the fixed guide 202, the limiter 204, and the component retaining band 4. Figure 29 , Figure 30 These are a top view and a perspective view showing the movable guide 200 and the component retaining band 4, respectively.

[0240] like Figures 27-30 As shown, the movable guide 200 has two contact portions 214 and 216. Contact portions 214 and 216 each have a lead wire 3R that connects to the component 3 located at the pitch adjustment position P3. Figure 27 (Diagram shown in dashed lines) The contact portions 214 and 216 in Embodiment 2 have the function of narrowing the spacing between the two leads 3R of the component 3.

[0241] like Figure 29 , Figure 30As shown, contact portions 214 and 216 each have a shape that protrudes laterally 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.

[0242] Inclined portions 214A and 216A are surfaces that are inclined relative to both the conveying direction A and the transverse direction B when viewed from above. Inclined portions 214A and 216A are inclined in opposite directions when viewed from above. On the other hand, non-inclined portions 214B and 216B are surfaces that extend in the transverse direction B when viewed from above.

[0243] The first inclined portion 214A contacts the rear side (upstream side A1) of the two leads 3R of the component 3 located at the pitch adjustment position P3. The first inclined portion 214A of Embodiment 1 has a conical shape that is inclined in a direction that is further away from the fixed guide 202 as it tends to the downstream side A2 of the conveying direction A.

[0244] The second inclined portion 216A contacts the lead 3R on the front side (downstream side A2) of the two leads 3R of the component 3 located at the pitch adjustment position P3. The second inclined portion 216A of Embodiment 1 has a conical shape that is inclined in a direction that is further away from the fixed guide 202 as it tends to the upstream side A1 of the conveying direction A.

[0245] The first non-inclined portion 214B is the portion that extends laterally B inside the first inclined portion 214A and connects to the first inclined portion 214A. The first non-inclined portion 214B abuts the lead wire 3R of the component 3 after it comes into contact with the first inclined portion 214A and restricts its movement upstream to the A1.

[0246] The second non-inclined portion 216B is the portion that extends laterally B inside the second inclined portion 216A and connects to the second inclined portion 216A. The second non-inclined portion 216B abuts the lead wire 3R of the component 3 after it comes into contact with the second inclined portion 216A and restricts its movement to the downstream side A2.

[0247] By providing non-tilted portions 214B and 216B, the spacing of the lead wire 3R, which is narrowed by the tilted portions 214A and 216A, can be limited to not widening.

[0248] Figure 29 , Figure 30 The distance D1 between the first non-tilted portion 214B and the second non-tilted portion 216B shown is set based on the desired spacing length of the lead 3R. In Embodiment 1, taking into account the springback of the lead 3R, the distance D1 between the non-tilted portions 214B and 216B is set to be shorter than the desired spacing length of the lead 3R.

[0249] The movable guide 200 also has a connecting portion 218. The connecting portion 218 is the portion that connects the first non-tilted portion 214B and the second non-tilted portion 216B, and extends along the conveying direction A. The connecting portion 218 is provided at a position that is recessed inward relative to the first non-tilted portion 214B and the second non-tilted portion 216B.

[0250] The position (depth) of the connecting part 218 is set such that when the movable guide 200 contacts the lead wire 3R of the component 3, the lead wire 3R and the connecting part 218 do not contact each other but are positioned opposite each other in the transverse direction B. The lead wire 3R of the component 3 only contacts the inclined parts 214A, 216A and the non-inclined parts 214B, 216B.

[0251] Figures 31-35 This is a perspective view showing the peripheral structure of the movable guide 200 and the fixed guide 202.

[0252] Figure 31 The diagram shows the movable guide 200 and the fixed guide 202 separately. Figure 32 This diagram shows the state in which the movable guide 200 is close to the fixed guide 202. Figure 33 The diagram shows the limiter 204 separately. Figure 34 This diagram shows the fixing guide 202, the limiter 204, and the component 3 held by the component holding band 4. Figure 35 Is Figure 34 The diagram shows a structure with a movable guide 200 added.

[0253] like Figure 31 As shown, the fixed guide 202 has an opposing surface 220 and two recesses 224 and 226.

[0254] Opposite surface 220 is with Figure 33 The limiting device 204 shown is opposed to the opposing surface 225. The main body 3B of the component 3 is sandwiched between the opposing surfaces 220 and 225, thereby... Figure 34 , Figure 35 The lateral movement of component 3, located at the spacing adjustment position P3, is restricted.

[0255] Recesses 224 and 226 are recesses used to support the contact portions 214 and 216 of the movable guide 200, respectively. Figure 32 As shown, when the movable guide 200 approaches the fixed guide 202, the recesses 224 and 226 respectively accommodate one end of the contact portions 214 and 216, thereby preventing interference between the movable guide 200 and the fixed guide 202.

[0256] like Figure 33As shown, the limiter 204 has an opposing surface 225. The opposing surface 225 has the function of clamping the main body 3B of the component 3 together with the opposing surface 220 of the aforementioned fixing guide 202, and is positioned at the same height as the main body 3B of the component 3.

[0257] use Figures 36A to 36D The method for adjusting the spacing of the lead wires 3R of the adjusting component 3 using the lead wire spacing adjustment mechanism 40B having the above-described structure will be described. Figures 36A to 36D This is a top view illustrating the method of adjusting the spacing of lead 3R using lead spacing adjustment mechanism 40B.

[0258] like Figure 36A As shown, the component holding belt 4 (not shown) is fed in the conveying direction A (conveyor step), and the new component 3 stops at the pitch adjustment position P3. With the stopping of component 3, the movable guide 200 is driven in the transverse direction B (arrow F1), and the contacts 214 and 216 advance toward the two leads 3R of component 3 located at the pitch adjustment position P3. Figure 36A In the example shown, the distance between the two leads 3R is the length D2.

[0259] If the movable guide 200 moves forward, then as Figure 36B The first contact portion 214 contacts the lead wire 3R on the rear side of component 3, and the second contact portion 216 contacts the lead wire 3R on the front side of component 3 (first contact step). In the first contact portion 214, the part that begins to contact the lead wire 3R of component 3 is the first inclined portion 214A, and in the second contact portion 216, the part that begins to contact the lead wire 3R of component 3 is the second inclined portion 216A.

[0260] Both inclined portions 214A and 216A have a conical shape that slopes inwards towards the connecting portion 218. Therefore, as the movable guide 200 moves forward (arrow F2), the two leads 3R are pressed towards each other (arrow F3). As a result, the distance between the leads 3R is gradually narrowed.

[0261] If the movable guide 200 moves further forward, then as Figure 36C The two leads 3R shown cross the inclined portions 214A and 216A and come into contact with the non-inclined portions 214B and 216B (second contact step). The non-inclined portions 214B and 216B have a shape in which the spacing in the conveying direction A remains constant, so during the forward movement of the movable guide 200, the two leads 3R are also subjected to pressure in the direction of narrowing of the spacing (arrow F4). At this time, the spacing of the leads 3R is temporarily narrowed to the aforementioned spacing D1 of the non-inclined portions 214B and 216B.

[0262] Component 3 is also pressed in the transverse direction B through contact with the inclined portions 214A and 216A, but as Figure 36B , Figure 36C As shown, the main body 3B of component 3 abuts against the fixed guide 202. Since a limiter 204 is also provided on the opposite side of the fixed guide 202, the spacing of the lead wire 3R is adjusted while the movement of component 3 in the lateral direction B at the spacing adjustment position P3 is restricted.

[0263] If from Figure 36C Starting from the state shown, the movable guide 200 retracts laterally in the horizontal direction B (arrow F5), then as follows Figure 36D As shown, the movable guide 200 moves to the retracted position, and the contact between the contacts 214, 216 and the lead wire 3R of the component 3 is released.

[0264] Since the lead wire 3R of component 3 is made of an elastic material, it springs back as contact with the contact portions 214 and 216 is released. As a result, the spacing of the lead wires 3R widens, becoming a length D3 (>D1 and <D2). Taking this springback into account, by setting the spacing D1 of the non-tilted portions 214B and 216B to be shorter than the desired length D3, the spacing of the lead wires 3R after springback can be changed to the desired length D3.

[0265] Next, the component holding belt 4 is fed in the conveying direction A, and the next component 3 stops at the spacing adjustment position P3. By reciprocating the movable guide 200 relative to the next component 3, the spacing of the lead wires 3R can be adjusted to the desired length. In this way, the spacing of the lead wires 3R can be adjusted for each component 3 conveyed on the conveying path TR.

[0266] Each component 3 is conveyed toward the pick-up position 13P with the leads 3R having the desired spacing. This allows for precise insertion of the component 3 when the component assembly mechanism 15 picks up the component 3 and inserts its leads 3R into the insertion holes of the substrate 2, reducing errors caused by the spacing of the leads 3R. Consequently, the supply efficiency of the component supply device 13 for supplying the component 3 is improved.

[0267] (Related functions and effects of the lead wire spacing adjustment mechanism 40B)

[0268] As described above, the component supply device 13 of Embodiment 1 includes: a transport path TR that transports the component 3 toward the pickup position 13P in the transport direction A; and a lead wire spacing adjustment mechanism 40B that adjusts the spacing of the leads 3R of the component 3 in the transport path TR. The lead wire spacing adjustment mechanism 40B includes: a movable guide 200 that can move in a transverse direction B intersecting the transport direction A; and a fixed guide 202 that is disposed at a position opposite to the movable guide 200 across the component 3. The movable guide 200 has contact portions 214 and 216 that can contact the two leads 3R of the component 3 when moved in a direction closer to the component 3. The contact portions 214 and 216 have inclined portions 214A and 216A that are inclined in a direction that narrows the spacing between the two leads 3R.

[0269] According to this structure, in the conveying path TR where the two leads 3R are conveyed at a distance from each other in the conveying direction A, the contact portions 214 and 216 of the movable guide 200 are brought into contact with the leads 3R, thereby allowing the spacing of the leads 3R to be adjusted. Thus, by adjusting the spacing of the leads 3R in the conveying path TR, the supply efficiency of the component supply device 13 for supplying the component 3 can be improved.

[0270] Furthermore, according to the component supply device 13 of Embodiment 1, the contact portions 214 and 216 also have non-inclined portions 214B and 216B extending along the transverse direction B inside the inclined portions 214A and 216A. With this structure, after the lead wire 3R of component 3 contacts the inclined portions 214A and 216A, it contacts the non-inclined portions 214B and 216B, thereby restricting the movement of the lead wire 3R in the transport direction A and making it easy to adjust the spacing of the lead wire 3R to a constant length.

[0271] Furthermore, according to the component supply device 13 of Embodiment 1, the contact portions 214 and 216 also have a connecting portion 218 (opposing portion) located inside the non-inclined portions 214B and 216B. The connecting portion 218 is positioned at a distance in the transverse direction B from the lead wire 3R of the component 3 that contacts the non-inclined portions 214B and 216B. With this structure, by preventing the lead wire 3R of the component 3 from contacting the connecting portion 218, it is possible to maintain the contact state between the lead wire 3R and the non-inclined portions 214B and 216B, and to suppress damage to the lead wire 3R caused by contact with the connecting portion 218.

[0272] Furthermore, according to the component supply device 13 of Embodiment 1, the fixed guide 202 is formed in the recesses 224 and 226 at the end of the movable guide 200 that receives the contact portions 214 and 216 when it approaches the fixed guide 202. With this structure, the movable guide 200 can be moved to a position closer to the fixed guide 202, for example, by lengthening the non-tilted portions 214B and 216B, and by designing the contact time and distance between the extended lead 3R and the non-tilted portions 214B and 216B.

[0273] Furthermore, according to the component supply device 13 of Embodiment 1, the lead wire spacing adjustment mechanism 40B also includes a limiter 204 which is positioned opposite the fixed guide 202, separated by the main stem 3B of the component 3, and arranged at a different height position relative to the movable guide 200. With this structure, the main stem 3B of the component 3 is sandwiched in the lateral direction B between the fixed guide 202 and the limiter 204, thereby stabilizing the posture of the component 3 when the movable guide 200 contacts the lead wire 3R and the spacing is adjusted. This improves the accuracy of the spacing adjustment.

[0274] Furthermore, the component supply device 13 according to Embodiment 1 includes: a first drive source 34 for feeding the component 3 in the transport path TR; and a second drive source 206 for driving the movable guide 200 in the transverse direction B. With this structure, the feeding action of the component 3 and the movement of the movable guide 200 can be performed independently.

[0275] Furthermore, the component supply device 13 in Embodiment 1 also includes a control unit 16. The control unit 16 intermittently performs the feeding operation of the component 3 based on the first drive source 34, and drives the movable guide 200 with the second drive source 206 during the period when the feeding of the component 3 stops. With this structure, interference between the movable guide 200 and the component 3 can be prevented, and the feeding operation of the component 3 and the spacing adjustment of the lead wire 3R can be performed separately.

[0276] Furthermore, the component mounting machine 1 of Embodiment 1 includes: a component supply device 13 having a lead pitch adjustment mechanism 40B; and a component assembly mechanism 15. The component assembly mechanism 15 picks up a component 3 from 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 lead pitch adjustment mechanism 40B.

[0277] Additionally, the component supply method of Embodiment 1 includes: a conveying step, in which the component 3 is conveyed toward the pickup position 13P in the conveying direction A; and a lead wire spacing adjustment step, in which the spacing of the leads 3R of the component 3 is adjusted. The lead wire spacing adjustment step performs a first contact step, in which a lead wire spacing adjustment mechanism 40B is used to move the movable guide 200 in a direction closer to the component 3, using a movable guide 200 that can move in a transverse direction B that intersects the conveying direction A and a fixed guide 202 disposed at a position opposite the movable guide 200 across the component 3, and to make the inclined portions 214A and 216A disposed on the movable guide 200 contact the leads 3R of the component 3 to widen the spacing of the leads 3R.

[0278] According to this method, the spacing of the lead wires 3R can be adjusted in the transport path TR, thereby improving the supply efficiency of component 3.

[0279] (Modifications related to the lead pitch adjustment mechanism 40B)

[0280] In Embodiment 2, the case where the lead spacing adjustment mechanism 40B narrows the spacing of the leads 3R of component 3 was described. However, it is not limited to this case; the adjustment can also be performed by widening the spacing of the leads 3R. In this case, by changing the tilting direction of the tilting portions 214A and 216A of the contact portions 214 and 216, the shape can be changed to widen the spacing of the leads 3R. Thus, the tilting portions 214A and 216A of the contact portions 214 and 216 can be tilted in the direction that widens or narrows the spacing between the two leads 3R.

[0281] (Implementation Method 3)

[0282] The component supply device according to Embodiment 3 of the present invention will be described. It should be noted that in Embodiment 3, the description mainly focuses on the differences from Embodiments 1 and 2, and the descriptions that are repeated in Embodiments 1 and 2 are omitted.

[0283] In Embodiment 2, the first component correction mechanism 40 is provided with a lead wire spacing adjustment mechanism 40B that adjusts the spacing between the two leads 3R of the component 3. However, in Embodiment 3, the first component correction mechanism 40 is provided with a "component correction mechanism 40C" that has both the function of adjusting the spacing of the leads 3R and the function of correcting the posture of the component 3. Hereinafter, the first component correction mechanism 40 will be described as the component correction mechanism 40C.

[0284] Figure 37 , Figure 38 These are, respectively, a perspective view and a top view of the component correction mechanism 40C of Embodiment 3.

[0285] The component straightening mechanism 40C includes a pusher 300, a rod member 302, a base 304, a second drive source 306, and a cam mechanism 308. The pusher 300, rod member 302, base 304, second drive source 306, and cam mechanism 308 are all mounted on the main body 43 of the device that forms the conveying path TR.

[0286] The pusher 300 is a component used to press the rod member 302 to rotate it. The pusher 300 is configured to move laterally B and move toward the member 3 which stops at the predetermined correction position P4 (pressing direction G1), and pass through the gap between the two leads 3R of the member 3, pressing the rod member 302.

[0287] The lever member 302 is a member that rotates by being pressed by the pusher 300. The lever member 302 is positioned opposite the pusher 300 across the conveying path TR. When the lever member 302 rotates, the limiting portions 336 and 340 of the lever member 302... Figure 40 The two leads 3R of component 3, which are located at the correction position P4, are opposite each other in the conveying direction A. The two leads 3R are sandwiched in the gap between the pusher 300 and the rod member 302, thereby positioning the leads 3R in a specified position and realizing the functions of correcting the spacing of the leads 3R and correcting the posture of component 3.

[0288] The base 304 is a component that supports the rod member 302 so that it can rotate. The base 304 is fixed to the main body 43 of the device.

[0289] The second drive source 306 is a drive source for reciprocating the pusher 300 in the transverse direction B. The second drive source 306 serves as a drive source for the aforementioned first drive source 34 (…). Figure 2 Different drive sources are provided, and an output shaft 307 capable of being driven along the conveying direction A is provided. In Embodiment 3, the second drive source 306 is a working 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.

[0290] The cam mechanism 308 is a mechanism for converting the driving force of the second drive source 306 along the conveying 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 engaged with the cam 310 and connected to the pusher 300. A cam groove 311 is formed at the front end of the cam 310, and a protrusion 313 of the cam follower 312 is engaged in the cam groove 311. The cam groove 311 has a top-view inclined shape such that when the cam 310 moves back and forth along the conveying direction A, the cam follower 312 moves along the lateral direction B. The cam follower 312 is mounted on the main body 43 of the device in a state where it can move in the lateral direction B and its movement in the back-and-forth direction is restricted.

[0291] According to this structure, if the second drive source 306 drives the output shaft 307 back and forth along the conveying direction A, the cam 310 moves back and forth, and the cam follower 312 engaged with the cam 310 reciprocates in the transverse direction B. Thus, the pusher 300 connected to the cam follower 312 can reciprocate in the transverse direction B. Figure 37 , Figure 38 The example shows the state where the pusher 300 is away from the rod member 302 (when not in operation).

[0292] Next, use Figures 39-42 The surrounding structure of the pusher 300 and the rod member 302 is described. Figures 39-42 The illustration of component 3 is omitted in the text.

[0293] Figure 39 It is a three-dimensional view obtained by enlarging the surrounding structure of the pusher 300 and the rod member 302.

[0294] like Figure 39 As shown, the pusher 300 has a pressing surface 314 for pressing the lever member 302. The pressing surface 314 is an end of the pusher 300 that protrudes in the transverse direction B and is opposite the lever member 302 in the transverse direction B. The pressing surface 314 is a surface that extends along the conveying direction A when viewed from above.

[0295] The rod member 302 has a first rod 316 and a second rod 318.

[0296] The first rod 316 and the second rod 318 are each configured to rotate, and their rotation is achieved by being pressed by the pressing surface 314 of the pusher 300. In embodiment 3, the first rod 316 and the second rod 318 are pressed in the pressing direction G1 by the same pressing surface 314 of the pusher 300.

[0297] The first rod 316 can rotate in the rotation direction R4 around the first rotation axis 317 extending along the Z-axis, and the second rod 318 can rotate in the rotation direction R5 around the second rotation axis 319 extending along the Z-axis. When the first rod 316 rotates, it is opposite to the rear (upstream A1) lead 3R of the two leads 3R of component 3. When the second rod 318 rotates, it is opposite to the front (downstream A2) lead 3R of the two leads 3R of component 3.

[0298] The component correction mechanism 40C also includes a force-applying component 320, a first limiter 322, and a second limiter 324.

[0299] The force-applying member 320 is a member used to apply force to the first rod 316 and the second rod 318. In Embodiment 3, the force-applying member 320 is a spring-like member that connects the first rod 316 and the second rod 318, and applies force in the direction that pulls the first rod 316 and the second rod 318.

[0300] The first rod 316 is forced by the force-applying member 320 in a rotational direction R6 opposite to the rotational direction of the lead wire 3R on the rear side of the component 3. The second rod 318 is forced by the force-applying member 320 in a rotational direction R7 opposite to the rotational direction of the lead wire 3R on the front side of the component 3. By providing the force-applying member 320, the first rod 316 and the second rod 318 can be pre-emptively retracted when not pressed by the pusher 300 (in non-operational state).

[0301] The first limiter 322 is a component that limits further rotation of the first rod 316, which is subjected to force by the force-applying member 320. The second limiter 324 is a component that limits further rotation of the second rod 318, which is subjected to force by the force-applying member 320. By setting the first limiter 322 and the second limiter 324, the first rod 316 and the second rod 318 are respectively stopped at a predetermined retraction position.

[0302] In addition to limiting the rotation of rods 316 and 318, the first limiter 322 and the second limiter 324 also help prevent the lead wire 3R of component 3 from falling off when rods 316 and 318 rotate due to the pressing of the pusher 300. Details will be described later.

[0303] Next, use Figures 40-42 The detailed structure of the pusher 300, the rod member 302, the force-applying member 320, and the limiters 322 and 324 is described. Figures 40-42 It is a perspective view of the pusher 300, the rod component 302, the force-applying component 320, and the limiters 322 and 324.

[0304] like Figures 40-42As shown, the pusher 300, in addition to the pressing surface 314, also has 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.

[0305] The first inclined surface 326 and the second inclined surface 328 are inclined relative to the conveying direction A and the transverse direction B, respectively, when viewed from above. The first inclined surface 326 is located opposite the first rod 316 in the transverse direction B, and the second inclined surface 328 is located opposite the second rod 318 in the transverse direction B.

[0306] The first inclined surface 326 and the second inclined surface 328 are inclined in different directions. The first inclined surface 326 is inclined further away from the rod member 302 as it approaches the upstream side A1 of the conveying direction A, while the second inclined surface 328 is inclined further away from the rod member 302 as it approaches the downstream side A2 of the conveying direction A.

[0307] The first opposing surface 330 and the second opposing surface 331 are respectively disposed on the inner sides of the first inclined surface 326 and the second inclined surface 328, and extend along the transverse direction B when viewed from above. The first opposing surface 330 and the second opposing surface 331 are respectively opposite to the lead wire 3R of component 3 from the side opposite to the rods 316 and 318 when the rods 316 and 318 have rotated. The first opposing surface 330, together with the first rod 316, is opposite to the lead wire 3R on the rear side of component 3, and the second opposing surface 331, together with the second rod 318, is opposite to the lead wire 3R on the front side of component 3.

[0308] By setting opposing surfaces 330 and 331, the lead wire 3R of component 3 can be clamped together with the rod member 302 in the conveying direction A and the lead wire 3R of component 3 can be positioned in a predetermined position. This allows adjustment of the distance between the two lead wires 3R and correction of the orientation of component 3 in the conveying direction A.

[0309] The third opposing surface 332 and the fourth opposing surface 333 are respectively disposed inside the first opposing surface 330 and the second opposing surface 331, and extend along the conveying direction A when viewed from above. The third opposing surface 332 and the fourth opposing surface 333 are respectively opposite to the lead wire 3R of the component 3 in the transverse direction B when the pusher 300 moves forward in the pressing direction G1. The third opposing surface 332 is opposite to the lead wire 3R on the rear side of the component 3, and the fourth opposing surface 333 is opposite to the lead wire 3R on the front side of the component 3.

[0310] like Figures 40-42 As shown, the first lever 316 has a first pressed portion 334 and a first limiting portion 336.

[0311] The first pressed portion 334 is an end that is pressed by the pressing surface 314 of the pusher 300, and is opposite to the pressing surface 314 in the transverse direction B. The first limiting portion 336 is an end at a different position from the first pressed portion 334, and is opposite to the lead wire 3R on the rear side of the component 3 when the first rod 316 has rotated.

[0312] like Figures 40-42 As shown, the second rod 318 has a second pressed portion 338 and a second limiting portion 340.

[0313] The second pressed portion 338 is one end that is pressed by the pressing surface 314 of the pusher 300, and is opposite to the pressing surface 314 in the transverse direction B. The second limiting portion 340 is an end at a different position from the second pressed portion 338, and contacts the lead wire 3R on the front side of the component 3 when the second rod 318 rotates.

[0314] like Figure 40 As shown, the first limiter 322 has a first rod abutment portion 342 and a first lead wire opposing portion 344.

[0315] The first rod abutment portion 342 is the portion that abuts against the first rod 316 that is subjected to force by the force-applying member 320 and prevents further rotation in the rotation direction R6. The first lead wire opposing portion 344 is the portion that faces the third opposing surface 332 of the pusher 300, which is separated from the lead wire 3R on the rear side of the member 3, when the pusher 300 advances in the pressing direction G1.

[0316] like Figure 40 As shown, the second limiter 324 has a second rod abutment portion 346 and a second lead wire opposing portion 348.

[0317] The second rod abutment portion 346 is the portion that abuts against the second rod 318 that is subjected to force by the force-applying member 320 and prevents further rotation in the rotation direction R7. The second lead wire opposing portion 348 is the portion that opposes the fourth opposing surface 333 of the pusher member 300, which is separated from the lead wire 3R on the front side of the member 3, when the pusher member 300 advances in the pressing direction G1.

[0318] use Figure 43A , Figure 43B A method for adjusting the spacing of the lead wires 3R of component 3 and correcting the posture of component 3 using the component correction mechanism 40C having the above-described structure will be described. Figure 43A , Figure 43B This is a top view illustrating the method of correcting component 3 using component correction mechanism 40C.

[0319] like Figure 43AAs shown, with the pusher 300 in the retracted position (non-operational), the component holding belt 4 is fed in the conveying direction A at intervals (conveying step), and one component 3 (shown by dashed lines) stops at the correction position P4. With the stopping of component 3, the second drive source 306 ( Figure 37 , Figure 38 The drive pusher 300 is moved forward in the pressing direction G1.

[0320] If the pusher 300 moves forward in the pressing direction G1, the pressing surface 314 of the pusher 300 passes between the two leads 3R and moves toward the pressed parts 334 and 338 of the rods 316 and 318.

[0321] like Figure 43B As shown, the pressing surface 314 of the pusher 300 contacts the pressed portions 334 and 338 of the rods 316 and 318, and presses in the pressing direction G1. The rods 316 and 318 rotate respectively. The first rod 316 rotates in the rotation direction R8 with the first rotation axis 317 as the center, and the second rod 318 rotates in the rotation direction R9 with the second rotation axis 319 as the center (component correction step).

[0322] As the first lever 316 rotates, the first limiting part 336 is positioned opposite the lead wire 3R on the rear side (upstream side A1) of component 3 in the first pressing direction H1. The first pressing direction H1 is towards the downstream side A2 of the conveying direction A. Figure 43B In the example shown, the first limiting part 336 contacts the lead wire 3R of component 3 and presses it in the first pressing direction H1. The lead wire 3R of component 3, pressed in the first pressing direction H1, is pressed toward the first opposing surface 330 of the advancing pusher 300. As a result, the rear lead wire 3R is positioned in the gap between the first limiting part 336 and the first opposing surface 330, and its movement in the forward and backward direction along the conveying direction A is restricted (first lead wire correction step).

[0323] The lead wire 3R is also sandwiched between the third opposing surface 332 of the advancing pusher 300 and the first lead wire opposing portion 344 of the first limiter 322. Therefore, the movement of the rear lead wire 3R in the lateral direction B is also restricted. In this way, the movement of the lead wire 3R in the horizontal direction is restricted.

[0324] It should be noted that the first limiting part 336 of the first lever 316, which rotates in the rotation direction R8, abuts against the first lead-opposing part 344 of the first limiter 322 and is restricted from further rotation. The first lead-opposing part 344 also functions as a limiter for the first lever 316.

[0325] As the second lever 318 rotates, the second limiting part 340 is positioned opposite the lead wire 3R on the front side (downstream side A2) of component 3 in the second pressing direction H2. The second pressing direction H2 is towards the upstream side A1 of the conveying direction A. Figure 43B In the example shown, the second limiting part 340 contacts the lead wire 3R of component 3 and presses it in the second pressing direction H2. The lead wire 3R of component 3, which is pressed in the second pressing direction H2, is pressed toward the second opposing surface 331 of the advancing pusher 300. As a result, the lead wire 3R on the front side is positioned in the gap between the second limiting part 340 and the second opposing surface 331, and its movement in the forward and backward direction along the conveying direction A is restricted (second lead wire correction step).

[0326] The lead wire 3R is also sandwiched between the fourth opposing surface 333 of the advancing pusher 300 and the second lead wire opposing portion 348 of the second limiter 324. Therefore, the movement of the lead wire 3R on the front side in the lateral direction B is also restricted. In this way, the movement of the lead wire 3R in the horizontal direction is restricted.

[0327] It should be noted that the second limiting part 340 of the second rod 318, which rotates in the rotation direction R9, abuts against the second lead-opposing part 348 of the second limiter 324 and is prevented from rotating further. The second lead-opposing part 348 also functions as a limiter for the second rod 318.

[0328] exist Figure 43B In the shown state, the two leads 3R are positioned at specified locations, thereby adjusting the spacing between the leads 3R to the desired length and correcting the orientation of component 3. Figure 43A In the unadjusted state shown, the spacing between the two leads 3R is wider than the desired spacing length. Figure 43B As shown, the limiting parts 336 and 340 press the two leads 3R closer to each other, thereby narrowing the gap between the leads 3R. At the same time, when the two leads 3R are tilted relative to the vertical direction (Z-axis direction), the component 3 is corrected to an upright posture.

[0329] Then, if the pusher 300 is driven in the retraction direction G2, which is opposite to the pressing direction G1, it returns to the position of... Figure 43A The state shown is the same as the state shown. The lead wire 3R springs back, but compared with the state before the pusher 300 is actuated, the spacing of the lead wire 3R is close to the desired spacing length, and the posture of the component 3 is close to the upright posture.

[0330] Next, the component 4 is fed along the conveying direction A, and the next component 3 is stopped at the correction position P4. By reciprocating the pusher 300 relative to the next component 3, the spacing of the lead wires 3R can be adjusted to the desired length, and the tilting of the component 3 can be corrected. In this way, the spacing of the lead wires 3R and the tilting of the component 3 can be adjusted for each component 3 conveyed on the conveying path TR.

[0331] Each component 3 is conveyed toward the pick-up position 13P with the desired spacing of its leads 3R. This allows for precise insertion when the component assembly mechanism 15 picks up the component 3 and inserts its leads 3R into the insertion holes of the substrate 2, reducing errors caused by the spacing of the leads 3R. Furthermore, since each component 3 is conveyed toward the pick-up position 13P while maintaining a generally upright posture, the success rate of picking up the component 3 by the component mounting machine 15 is improved. This, in turn, improves the supply efficiency of the component supply device 13 for supplying the component 3.

[0332] It should be noted that, in Figure 43A , Figure 43B The example shown illustrates a case where the spacing between the two leads 3R is wider before the actuator 300 is activated, and then the spacing between the leads 3R is narrowed. However, this is not a limitation; the spacing between the leads 3R can also be adjusted by widening it. For example, in... Figure 43A In the state before adjustment, when the distance between the two leads 3R is narrow, as the pusher 300 moves forward, 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. Corresponding to the respective 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. Thus, the distance between the two leads 3R widens, and... Figure 43B As shown, the lead wires 3R are positioned at predetermined locations. In this way, even when the spacing of the lead wires 3R is narrow, the spacing of the lead wires 3R can be widened by using the inclined surfaces 326 and 328, and the orientation of the component 3 can be corrected.

[0333] (The function and effect related to the 40C component correction mechanism)

[0334] As described above, the component supply device 13 of Embodiment 3 includes: a transport path TR that transports the component 3 toward the pickup position 13P in the transport direction A; and a component correction mechanism 40C for correcting the component 3 in the transport path TR. The component correction mechanism 40C includes: a pusher 300 that is movable in a transverse direction B intersecting the transport direction A in a manner that passes between the leads 3R; and a rod member 302 that is pressed by the pusher 300 and rotates. The rod member 302 has a first rod 316 and a second rod 318. The first rod 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 clamps the lead 3R (first lead) of the component 3 between the first opposing surface 330 of the pusher 300. The second rod 318 rotates around the second rotation axis 319 in response to the pressing of the pressing surface 314 (second pressing surface) of the pusher 300, and the lead wire 3R (second lead wire) of the component 3 is sandwiched between the second opposing surface 331 of the pusher 300.

[0335] According to this structure, by using the pusher 300 and the two rods 316 and 318 to clamp the two lead wires 3R, the spacing between the two lead wires 3R can be adjusted or the tilting of the component 3 can be corrected. As a result, the supply efficiency of the component supply device 13 to the component 3 can be improved.

[0336] Furthermore, according to the component supply device 13 of Embodiment 3, the first rod 316 has a first limiting portion 336 that clamps the lead wire 3R (first lead wire) between the first opposing surface 330 of the pusher 300 and restricts the movement of the lead wire 3R in the conveying direction A, and the second rod 318 has a second limiting portion 340 that clamps the lead wire 3R (second lead wire) between the second opposing surface 331 of the pusher 300 and restricts the movement of the lead wire 3R in the conveying direction A. With this structure, by restricting the movement of the two lead wires 3R in the conveying direction A, the spacing adjustment of the lead wires 3R and the tilting correction of the component 3 can be performed with high precision.

[0337] Furthermore, according to the component supply device 13 of embodiment 3, the pusher 300 also includes: a third opposing surface 332, which is opposed in the transverse direction B to the lead wire 3R (first lead wire) sandwiched between the first opposing surface 330 and the first rod 316; and a fourth opposing surface 333, which is opposed in the transverse direction B to the lead wire 3R (second lead wire) sandwiched between the second opposing surface 331 and the second rod 318. With this structure, the opposing surfaces 332 and 333 can be used to prevent the lead wire 3R from falling off in the transverse direction B.

[0338] Furthermore, according to the component supply device 13 of Embodiment 3, the pusher 300 also includes: 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. With this structure, particularly when the spacing of the leads 3R is narrow, the leads 3R of the component 3 can contact the inclined surfaces 326 and 328 and be guided toward the opposing surfaces 330 and 331.

[0339] Furthermore, according to the component supply device 13 of Embodiment 3, the first rod 316 is positioned upstream of the second rod 318 in the conveying direction A. The first inclined surface 326 has a shape that is inclined towards the upstream side A1 of the conveying direction A, away from the first rod 316, and the second inclined surface 328 has a shape that is inclined towards the downstream side A2 of the conveying direction A, away from the second rod 318. With this structure, the front end of the pusher 300 can be miniaturized.

[0340] Furthermore, according to the component supply device 13 of Embodiment 3, the pressing surface 314 (first pressing surface) of pressing the first rod 316 and the pressing surface 314 (second pressing surface) of pressing the second rod 318 are formed on the same surface of the pusher 300. With this structure, the structure of the pusher 300 can be simplified.

[0341] Furthermore, according to the component supply device 13 of Embodiment 3, the component correction mechanism 40C also includes a force-applying member 320, which applies force to the first rod 316 in the rotational direction R6 of the lead wire 3R (first lead wire) away from the rear side of the component 3, and applies force to the second rod 318 in the rotational direction R7 of the lead wire 3R (second lead wire) away from the front side of the component 3. With this structure, the rod member 302 can be preemptively retracted when not pressed by the pusher 300.

[0342] Furthermore, according to the component supply device 13 of Embodiment 3, the component correction mechanism 40C further includes: a first limiter 322, which abuts against a first rod 316 subjected to force by the force-applying member 320 (first force-applying member) to limit further rotation of the first rod 316; and a second limiter 324, which abuts against a second rod 318 subjected to force by the force-applying member (second force-applying member) to limit further movement of the second rod 318. With this structure, the rods 316 and 318 subjected to force by the force-applying member 320 can be pre-positioned in a predetermined retraction position away from the transport path TR.

[0343] Furthermore, according to the component supply device 13 of Embodiment 3, the first limiter 322 is positioned opposite the lead wire 3R (first lead wire) sandwiched between the first opposing surface 330 and the first rod 316 of the pusher 300 in the transverse direction B, and the second limiter 324 is positioned opposite the lead wire 3R (second lead wire) sandwiched between the second opposing surface 331 and the second rod 318 of the pusher 300 in the transverse direction B. With this structure, the limiters 322 and 324 can prevent the lead wire 3R from falling off in the transverse direction B.

[0344] Furthermore, according to the component supply device 13 of Embodiment 3, a common force-applying member 320 applies force to the first rod 316 and the second rod 318. With this structure, the number of components in the component correction mechanism 40C can be reduced, and costs can be lowered.

[0345] Furthermore, the component mounting machine 1 of Embodiment 3 includes: a component supply device 13 having a component correction mechanism 40C; and a component assembly mechanism 15. The component assembly mechanism 15 picks up a component 3 from 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 component correction mechanism 40C.

[0346] Additionally, the component supply method of Embodiment 3 includes: a conveying step, in which component 3 is conveyed toward pickup position 13P in conveying direction A; and a component correction step, in which component 3 is corrected. The component correction step uses component correction mechanism 40C to perform a first lead wire correction step and a second lead wire correction step. In the first lead wire correction step, the first rod 316 of the pusher member 302 is rotated by pressing the pressing surface 314 (first pressing surface) of the pusher member 300, thereby clamping the lead wire 3R (first lead wire) of component 3 between the first opposing surface 330 of the pusher member 300 and the first rod 316. In the second lead wire correction step, the second lead wire correction step is performed by pressing the second rod 318 of the pusher member 302 by pressing the pressing surface 314 (second pressing surface) of the pusher member 300, thereby clamping the lead wire 3R (second lead wire) of component 3 between the second opposing surface 331 of the pusher member 300 and the second rod 318.

[0347] According to this component supply method, two lead wires 3R are clamped between a pusher 300 and two rods 316 and 318, thereby adjusting the spacing of the lead wires 3R or correcting the tilting of the component 3. This improves the supply efficiency of the component 3.

[0348] (Modifications related to component straightening mechanism 40C)

[0349] In Embodiment 3, the case where two rods 316 and 318 are pressed using a single pusher 300 is described, but the method is not limited to this; different pushers can also be used to press the two rods separately. Figures 44-45B This variation will be explained.

[0350] Figure 44 This is a perspective view of the component correction mechanism 40D, which is a modified example of embodiment 3. Figure 45A , Figure 45B This is a top view illustrating the method of correcting component 3 using the component correction mechanism 40D of this variant.

[0351] Figure 44 The component correction mechanism 40D shown has two pushers 400A and 400B and two rods 416 and 418.

[0352] The first pusher 400A is a component used to press the first rod 416 to rotate it, and the second pusher 400B is a component used to press the second rod 418 to rotate it. The first pusher 400A, together with the first rod 416, positions the lead wire 3R (not shown) on the rear side of component 3 at the first correction position P5. The second pusher 400B, together with the second rod 418, positions the lead wire 3R (not shown) on the rear side of component 3 at the second correction position P6.

[0353] In this modified example, two pushers 400A and 400B are integrally formed and driven in the transverse direction B by the same drive source (e.g., the second drive source 306 of embodiment 3).

[0354] 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, components with the same names as those in Embodiment 3 have the same structure and function as the components already described in Embodiment 3, and detailed descriptions are omitted.

[0355] The first rod 416 is rotatable about the first rotation axis 417 and has a first pressing part 434 and a first limiting part 436. The first force-applying member 420A applies force to the first rod 416 in the rotation direction R10. The first support part 421A is a shaft-shaped member that supports one end of the spring-shaped first force-applying member 420A and is mounted on the base 404 together with the first rotation axis 417. The first limiter 422 limits further rotation of the first rod 416, which is subjected to force by the first force-applying member 420A, in the rotation direction R10.

[0356] 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.

[0357] The second rod 418 is rotatable about the second rotation axis 419 and has a second pressed portion 438 and a second limiting portion 440. The second force-applying member 420B applies force to the second rod 418 in the rotation direction R11. The second support portion 421B is a shaft-shaped member that supports one end of the spring-shaped second force-applying member 420B and is mounted on the base 404 together with the second rotation axis 419. The second limiter 424 limits further rotation of the second rod 418, which is subjected to force by the second force-applying member 420B, in the rotation direction R11.

[0358] like Figure 45A As shown, with pushers 400A and 400B in the retracted position (not in operation), the component holding belt 4 is conveyed in the conveying direction A. One component 3 stops at the first correction position P5, and the adjacent component 3 stops at the second correction position P6. As component 3 stops, pushers 400A and 400B are driven in the pressing direction G3.

[0359] If 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 located in the first correction position P5 and advances toward the first pressed portion 434 of the first rod 416. Similarly, the second pressing surface 414B of the second pusher 400B passes between the two leads 3R of the component 3 located in the second correction position P6 and advances toward the second pressed portion 438 of the second rod 418.

[0360] like Figure 45B As shown, the first pressing surface 414A of the first pusher 400A presses against the first rod 416, and the first rod 416A rotates in the rotation direction R12. The first limiting part 436 of the first rod 416 is at the first opposing surface 430 of the advanced first pusher 400A ( Figure 45A The lead wire 3R of component 3 is positioned between the first pusher 400A and the first limiter 422. The lead wire 3R is also sandwiched between the third opposing surface 432 of the first pusher 400A and the first limiter 422, and its horizontal movement is restricted.

[0361] Similarly, the second pressing surface 414B of the second pusher 400B presses against the second rod 418, causing the second rod 418 to rotate in the rotation direction R13. The second limiting portion 440 of the second rod 418 is positioned opposite the second opposing surface 431 of the advanced second pusher 400B. Figure 45A The lead wire 3R on the front side of component 3 is positioned between the two. The lead wire 3R is also sandwiched between the fourth opposing surface 433 of the second pusher 400B and the second limiter 424, and its horizontal movement is restricted.

[0362] Based on the above actions, the lead wire 3R on the rear side of component 3 at the first correction position P5 is positioned at a predetermined position, and the lead wire 3R on the front side of component 3 at the second correction position P6 is positioned at a predetermined position. Thus, the posture of component 3 can be corrected at correction positions P5 and P6 respectively, and the distance between the two lead wires 3R can ultimately be adjusted to the desired length. Furthermore, by stopping component 3 sequentially at the first correction position P5 and the second correction position P6, regardless of whether component 3 is tilted to the front or rear, its posture can be corrected towards an upright position while considering rebound.

[0363] The present invention has been described above using embodiments 1 to 3, but the present invention is not limited to embodiments 1 to 3. For example, the attitude correction mechanism 40A of embodiment 1 and the lead wire spacing adjustment mechanism 40B of embodiment 2 may be provided in the same component supply device 13. In this way, the attitude of component 3 can be corrected midway through the transport path TR, and the spacing of lead wires 3R can be adjusted.

[0364] Although the present invention has been fully described with reference to the accompanying drawings and preferred embodiments, various modifications and variations will be apparent to those skilled in the art. It should be understood that such modifications and variations are 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.

[0365] It should be noted that by appropriately combining the above-described embodiments and any of the embodiments and variations, the respective effects can be achieved.
