Detailed Description

Exemplary embodiments of a component feeder, a component mounter provided with the component feeder, and a component feeding method according to the present invention will be described below with reference to the accompanying drawings. The present invention is not limited to the specific configuration of the following embodiments, and configurations based on the same technical ideas are also included in the present invention.

(embodiment)

Fig. 1 shows a component mounter 1 according to an embodiment of the present invention. The component mounter 1 is a device that mounts components 3 onto a board 2. The component mounter 1 includes a base 11, a substrate conveying mechanism 12, a plurality of component feeders 13, a component camera 14, a component mounting mechanism 15, and a control unit 16. For convenience of explanation, the left-right direction of the component mounter 1 viewed from the operator OP is referred to as the X-axis direction, the front-rear direction is referred to as the Y-axis direction, and the up-down direction is referred to as the Z-axis direction.

In fig. 1, a substrate conveying mechanism 12 conveys a substrate 2 in the X-axis direction by a pair of conveyor mechanisms 12a to be positioned at a predetermined working position near the center of a base 11. The plurality of component supply devices 13 are arranged in a row on a carriage 11D mounted on the base 11.

In fig. 1, the component supply devices 13 each include a component supply port 13K on the tip end side, and continuously supply the components 3 to a pickup position 13P (see fig. 2) immediately below the component supply port 13K. In the embodiment, the component 3 supplied by the component supply device 13 is a radial component (radial braid component) with a lead wire, and as shown in fig. 3, has a cylindrical main body 3B and two lead wires 3R extending downward from the main body 3B.

In fig. 1, a component camera 14 is provided in an area between the substrate conveyance mechanism 12 and the component supply device 13. The component camera 14 captures the component 3 picked up by the component mounting mechanism 15 from below with the imaging field of view directed upward.

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

In fig. 1, the mounting head 22 includes a plurality of suction nozzles 22a. Each suction nozzle 22a extends downward, has a lower end that is a component suction port, and is configured to be movable up and down in the Z-axis direction. The mounting head 22 includes an adsorption control mechanism 22b, and the adsorption control mechanism 22b is connected to a vacuum source, not shown. The suction control means 22b controls the vacuum pressure supplied from the vacuum source, thereby generating a vacuum suction force at the component suction ports of the respective suction nozzles 22a.

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

The control unit 16 is a means for controlling the operation of the component mounter 1. The control unit 16 is electrically connected to each component of the component mounter 1, and controls the operation of each component. The control unit 16 has, for example, a microcomputer. The control unit 16 displays content related to the operation state of the component mounter 1 on the touch panel 101, and receives an input from the operator OP.

In fig. 2, each component supply device 13 includes a base portion 31 coupled to a carriage 11D (see fig. 1), and a cover portion 32 attached to the base portion 31. The component holding tape 4 is provided in the region covered by the cover portion 32 on the base portion 31. The component holding tape 4 is a tape-shaped member holding the leads 3R of the plurality of components 3, and travels at intervals in the conveyance direction a along the Y-axis direction on the conveyance path TR provided inside the cover portion 32.

As shown in fig. 2, a first drive source 34 for advancing the component holding tape 4 at a pitch is provided inside the component supply device 13. The first drive source 34 of the present embodiment is a cylinder having an output shaft 35, and drives the output shaft 35 back and forth in the conveying direction a. The first drive source 34 is drive-controlled by the control unit 16.

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

In the component supply device 13 shown in fig. 2, a bending mechanism 40 is provided as a mechanism for bending the lead 3R of the component 3 conveyed along the conveying path TR. In fig. 2, the general installation position of the bending mechanism 40 is shown by a broken line, and the specific structure is not illustrated.

By providing the bending mechanism 40 in the component feeder 13, the lead 3R of the component 3 can be bent in the middle of the conveying path TR, and the feeding efficiency of the component 3 by the component feeder 13 can be improved.

The structure and operation of the bending mechanism 40 will be described below with reference to fig. 4 and the following drawings.

Fig. 4 and 5 are a perspective view and a plan view, respectively, of the bending mechanism 40 according to the embodiment. Fig. 6 and 7 are perspective views showing the movable guide 44 and the fixed guide 46, respectively, with parts of the bending mechanism 40 omitted from illustration.

The bending mechanism 40 includes a movable guide 44, a fixed guide 46, a second drive source 48, and a cam mechanism 50. The movable guide 44, the fixed guide 46, the second drive source 48, and the cam mechanism 50 are mounted on the apparatus main body 43 forming the conveyance path TR.

The movable guide 44 and the fixed guide 46 are members for sandwiching the lead 3R of the component 3 therebetween to bend the lead 3R of the component 3.

The movable guide 44 is a guide portion configured to be movable in a lateral direction B, which is a direction intersecting the conveying direction a. The lateral direction B of the embodiment is a horizontal direction orthogonal to the conveying direction a, and corresponds to the X-axis direction. The fixed guide 46 is disposed at a position facing the movable guide 44 with the transport path TR interposed therebetween, and is fixed to the apparatus body 43.

The region between the movable guide 44 and the fixed guide 46 includes a pitch adjustment position P1 for adjusting the pitch of the lead 3R, and a bend forming position P2 for forming a bend. The pitch adjustment position P1 is located on the upstream side A1, and the bending formation position P2 is located on the downstream side A2. The member 3 is conveyed downstream A2 after stopping at the pitch adjustment position P1, and stops at the bending position P2. The pitch adjustment position P1 and the bending position P2 of the present embodiment are provided at positions separated by two pitches.

The second drive source 48 is a drive source for reciprocating the movable guide 44 in the lateral direction B. The second drive source 48 is provided as a drive source different from the first drive source 34 (fig. 2) described above, and has an output shaft 49 that can be driven in the conveying direction a. The second drive source 48 of the embodiment is a cylinder that drives the output shaft 49 back and forth. An output shaft 49 of the second drive source 48 is coupled to a cam mechanism 50.

The cam mechanism 50 is a mechanism for converting a driving force in the conveying direction a based on the second driving source 48 into a driving force in the lateral direction B and transmitting the driving force to the movable guide 44. The cam mechanism 50 includes a cam 54 coupled to the output shaft 49, and a cam follower 56 engaged with the cam 54 and coupled to the movable guide 44. A cam groove 55 is formed at the front end of the cam 54, and a projection 58 of the cam follower 56 engages with the cam groove 55. The cam groove 55 has a shape inclined in a plan view, which moves the cam follower 56 in the lateral direction B when the cam 54 moves back and forth in the conveying direction a. The cam follower 56 is attached to the apparatus main body 43 in a state of being movable in the lateral direction B and being restricted from moving in the front-rear direction.

According to such a configuration, when the second drive source 48 drives the output shaft 49 back and forth in the conveying direction a, the cam 54 moves back and forth, and the cam follower 56 engaged with the cam 54 moves back and forth in the lateral direction B. Thereby, the movable guide 44 coupled to the cam follower 56 can be reciprocally moved in the lateral direction B. Fig. 4 and 5 show a state (advanced state) in which the movable guide 44 approaches the fixed guide 46, and fig. 6 and 7 show a state (retracted state) in which the movable guide 44 is away from the fixed guide 46.

As shown in fig. 6 and 7, the movable guide 44 has two kinds of

contact portions

60 and 62 as portions that contact the lead 3R of the component 3. The contact portion 60 is provided at the pitch adjustment position P1, and the contact portion 62 is provided at the bending formation position P2. The contact portion 60 functions to adjust the pitch of the leads 3R when contacting the leads 3R of the component 3 positioned at the pitch adjustment position P1, and the contact portion 62 functions to bend a part of the leads 3R to form a bend when contacting the leads 3R of the component 3 positioned at the bend formation position P2.

The detailed structure of the movable guide 44 will be described with reference to fig. 8 and 9. Fig. 8 and 9 are perspective views showing the movable guide 44.

As shown in fig. 8 and 9, the contact portion 60 of the present embodiment has two

claw portions

60A and 60B. The

claw portions

60A and 60B each have a shape protruding in the lateral direction B toward the lead 3R (not shown) of the member 3, and are a pair of claw portions provided at intervals along the conveying direction a. The

claw portions

60A and 60B of the present embodiment contact each other so as to sandwich the two leads 3R of the component 3 positioned at the pitch adjustment position P1 in the conveying direction a, and function to narrow the pitch of the leads 3R to a predetermined pitch or less.

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

The

inclined portions

64A and 64B are inclined with respect to both the conveying direction a and the lateral direction B in a plan view. The

non-inclined portions

65A and 65B are surfaces extending in the lateral direction B in a plan view.

The inclined portion 64A contacts the lead 3R on the rear side (upstream side A1) of the two leads 3R of the component 3 located at the pitch adjustment position P1. The inclined portion 64B 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 P1. The inclined portion 64A has a tapered shape inclined in a direction away from the fixed guide 46 as going toward the downstream side A2 of the conveying direction a, and the inclined portion 64B has a tapered shape inclined in a direction away from the fixed guide 46 as going toward the upstream side A1 of the conveying direction a.

The non-inclined portion 65A extends in the lateral direction B inside the inclined portion 64A and is connected to the inclined portion 64A. The non-inclined portion 65B extends in the lateral direction B inside the inclined portion 64B and is connected to the inclined portion 64B. By providing the

non-inclined portions

65A, 65B, the pitch of the leads 3R of the component 3 after contact with the

inclined portions

64A, 64B is restricted to be not widened.

The interval L1 between the non-inclined portion 65A and the non-inclined portion 65B shown in fig. 9 is set based on the required pitch length of the lead 3R. In the present embodiment, the distance L1 between the

non-inclined portions

65A and 65B is set shorter than the pitch length of the lead 3R in consideration of springback of the lead 3R.

The contact portion 60 is constituted by two

claw portions

60A and 60B, and the contact portion 62 is constituted by one claw portion. The contact portion 62 has a tapered shape (inclined shape) which becomes narrower as it approaches the tip end side. The contact portion 62 of the present embodiment contacts the two leads 3R of the member 3 located at the bending position P2 from the inside, and bends a part of the leads 3R to the outside to form a bend.

The contact portion 62 has two

inclined portions

66A, 66B and a front end face 68.

The

inclined portions

66A and 66B are inclined with respect to both the conveying direction a and the lateral direction B in a plan view. The inclined portion 66A is in contact with the lead 3R on the rear side (upstream side A1) of the two leads 3R of the member 3 located at the bending position P2, and the inclined portion 66B is in contact with the lead 3R on the front side (downstream side A2) of the two leads 3R of the member 3 located at the bending position P2. The inclined portion 66A has a shape inclined in a direction away from the fixed guide 46 as the upstream side A1 of the conveying direction a is moved, and the inclined portion 66B has a shape inclined in a direction away from the fixed guide 46 as the downstream side A2 of the conveying direction a is moved.

The

inclined portions

66A and 66B each have a shape in which a part (central portion) in the Z direction protrudes outward. By providing the

inclined portions

66A and 66B with protruding portions so that the protruding portions are in contact with the lead 3R of the component 3, the entire lead 3R is not bent, and a part of the lead 3R is easily bent to form a bend.

The front end surface 68 is a surface constituting the front end of the contact portion 62. The front end surface 68 is provided at a position facing a recess 72 of the fixed guide 46 described later, and performs opening and closing operations of the

shutter members

74A, 74B.

Returning to fig. 7, the fixed guide 46 forms two

recesses

70, 72. The

recesses

70, 72 form spaces for accommodating the

contact portions

60, 62 of the movable guide 44 when the movable guide 44 approaches, respectively. The concave portion 70 is provided at the pitch adjustment position P1 to accommodate the contact portion 60, and the concave portion 72 is provided at the bending formation position P2 to accommodate the contact portion 62.

The detailed structure of the fixing guide 46 will be described with reference to fig. 10 and 11. Fig. 10 is a perspective view showing the fixing guide 46, and fig. 11 is a front view showing the recess 72 of the fixing guide 46 in an enlarged manner.

As shown in fig. 10, the recess 70 is continuously formed to have a size capable of accommodating a pair of

claw portions

60A, 60B (not shown) of the contact portion 60. In a state where the

claw portions

60A, 60B are arranged in the concave portion 70, the

claw portions

60A, 60B are not in contact with the fixed guide 46.

The recess 72 is continuously formed to have a size capable of accommodating the contact portion 62 (not shown). The recess 72 forms an opening corresponding to the front end surface 68 of the contact portion 62, and has a tapered shape that is narrower toward the inner side. The inner side of the recess 72 has an inclined shape corresponding to the inclined shape of the

inclined portions

66A, 66B of the contact portion 62.

The recess 72 is constituted by a pair of

shutter members

74A, 74B. The

shutter members

74A and 74B are a pair of members configured to open and close in a direction (Y direction) along the conveying direction a in response to contact with the contact portion 62.

The

shutter members

74A, 74B have facing

surfaces

76A, 76B, respectively. The facing surfaces 76A and 76B are surfaces provided so as to face the lead 3R of the component 3 in the lateral direction B, and receive and support the lead 3R pressed by the contact portion 62.

When the

inclined portions

66A, 66B of the contact portion 62 press the lead 3R, the lead 3R is pressed in a direction widening along the conveying direction a, and is also pressed in the lateral direction B. By supporting the lead 3R in the lateral direction B by the opposing

surfaces

76A, 76B, the deformation of the lead 3R in the lateral direction B can be prevented, and bending in the conveying direction a can be easily performed.

The

shutter members

74A and 74B are biased in the closing direction (arrows C1 and C2) by a biasing member (not shown).

Here, the operation of the

shutter members

74A and 74B will be described with reference to fig. 11. As shown in fig. 11 a, in the non-contact state in which the contact portion 62 is not in contact with the

shutter members

74A, 74B, the

shutter members

74A, 74B are maintained in the closed state (arrows C1, C2). At this time, the opening area of the concave portion 72 becomes minimum, and the opposing

surfaces

76A, 76B around the concave portion 72 are exposed to the largest area. As indicated by the broken line, when the lead 3R pressed by the contact portion 62 is disposed, the opposing

surfaces

76A and 76B receive and support the lead 3R.

Then, when the movable guide 44 advances toward the fixed guide 46, the front end surface 68 of the contact portion 62 enters the opening of the recess 72. As shown in fig. 11B, the

shutter members

74A and 74B are pushed outward (arrows D1 and D2) by contact with the contact portion 62. Even if the

shutter members

74A and 74B are widened, the contact portion 62 is buried in the recess 72, so that the lead 3R does not enter the recess 72 and is maintained in a state supported by the facing

surfaces

76A and 76B. As shown by the broken line, in a state where the lead 3R is bent 3K, the opposing

surfaces

76A, 76B oppose the entire lead 3R including the bent 3K.

According to the above-described operation, the

shutter members

74A and 74B are opened in response to the contact with the contact portion 62, whereby the surface receiving the lead 3R by the opposing

surfaces

76A and 76B can be ensured to be large, and the contact portion 62 can be advanced further inward, so that the lead 3R can be easily bent outward.

As shown in fig. 11,

concave portions

77A, 77B are formed in front of the opposing

surfaces

76A, 76B. The

concave portions

77A and 77B are concave portions for accommodating the lead 3R pressed by the contact portion 62. The

concave portions

77A and 77B each have a shape that corresponds to a portion where the bend 3K is formed and a part of which widens outward.

Although not shown in fig. 6 and 7, the movable guide 44 is provided with an auxiliary member for assisting the pitch adjustment operation and the bending operation. The structure and operation of the auxiliary member will be described with reference to fig. 12 to 14B.

Fig. 12 is a perspective view showing the peripheries of the movable guide 44 and the fixed guide 46, and fig. 13A and 13B are side views when the peripheries are viewed along the conveying direction a.

As shown in fig. 12, the movable guide 44 is attached with an attachment portion 82, a first pressing portion 84, and a second pressing portion 86.

The mounting portion 82 is a member for mounting the first pressing portion 84 and the second pressing portion 86 to the movable guide 44. By attaching the first pressing portion 84 and the second pressing portion 86 to the movable guide 44 by the attachment portion 82, the first pressing portion 84 and the second pressing portion 86 move integrally with the movable guide 44 in the lateral direction B.

The first pressing portion 84 is a member for pressing the main body 3B of the member 3 located at the bending position P2 toward the fixed guide 46. The main body 3B of the member 3 is pressed in the lateral direction B by the first pressing portion 84, so that the whole of the member 3 is pressed toward the fixed guide 46.

The second pressing portion 86 is a member for pressing the main body 3B of the member 3 located at the bending position P2 in a direction opposite to the first pressing portion 84. The second pressing portion 86 has a substantially L-shaped cross-sectional shape, and extends to a position opposite to the first pressing portion 84 across the conveying path TR. After being pressed toward the fixed guide 46 by the first pressing portion 84, the main body 3B of the member 3 is pressed in a direction away from the fixed guide 46 by the second pressing portion 86 and returns to the conveying path TR when the movable guide 44 is retracted.

The first pressing portion 84 of the present embodiment is configured to be rotatable about a rotation axis Ax passing through the mounting portion 82. The first pressing portion 84 is biased in the rotation direction R1 by a biasing member such as a spring, and is stationary at a predetermined stop position in a biased state. When an external force is applied to the first pressing portion 84 on the opposite side to the rotation direction R1, the first pressing portion 84 can rotate to the opposite side to the rotation direction R1. On the other hand, the second pressing portion 86 is fixed to the mounting portion 82 and cannot move relative to the mounting portion 82.

According to the above configuration, as shown in fig. 13A, in a state where the movable guide 44 is retracted (arrow E1), the member 3 positioned at the bending position P2 is arranged between the first pressing portion 84 and the second pressing portion 86, and the first pressing portion 84 is biased in a direction toward the main body 3B of the member 3 (arrow R1), but is stopped at a position before contacting the main body 3B.

As shown in fig. 13B, when the movable guide 44 advances toward the fixed guide 46 (arrow E2), the first pressing portion 84 contacts the main body 3B of the member 3 to press the main body 3B toward the fixed guide 46 (arrow E2). When the lead 3R is brought into contact with the contact portion 62 in a state where the main body 3B of the member 3 is pressed against the fixing guide 46, the lead 3R is easily bent outward to form the bend 3K. At this time, the first pressing portion 84 is rotatable in a direction opposite to the urging force (arrow R2), so that it is possible to avoid applying an excessive pressing force to the main body 3B while pressing the main body 3B against the fixed guide 46 with a sufficient force. This can suppress breakage of the member 3.

Then, when the movable guide 44 is retracted, the state shown in fig. 13A is returned (arrow E1). At this time, the main body 3B of the member 3 is pressed by the second pressing portion 86 (arrow E1) and returns to the original position.

In the present embodiment, the moving direction of the movable guide 44 is set to be inclined with respect to the horizontal direction. As shown in fig. 13B, the movable guide 44 moves obliquely downward (arrow E2) when advancing toward the fixed guide 46, and moves obliquely upward (arrow E1) when retracting away from the fixed guide 46 as shown in fig. 13A. Thus, when the movable guide 44 moves forward and comes into contact with the lead 3R of the component 3, the component 3 can be prevented from being lifted, and the load on the component 3 can be suppressed.

Returning to fig. 12, a fixing guide 90 different from the fixing guide 46 is provided at the pitch adjustment position P1. The fixed guide 90 is a guide portion provided on the opposite side of the fixed guide 46 across the conveyance path TR. The fixed guide 90 is located at the same height position as the main body 3B of the component 3, and guides the main body 3B of the component 3 conveyed in the conveying direction a to a predetermined position of the pitch adjustment position P1. By providing the fixing guide 90, the position of the member 3 can be stabilized.

The operation of the bending mechanism 40 having the above-described structure will be described with reference to fig. 14A and 14B. Fig. 14A and 14B are perspective views for explaining the operation of the bending mechanism 40, and the auxiliary members shown in fig. 13A and 13B are omitted.

As shown in fig. 14A, in a state where the movable guide 44 is retracted (arrow E1), neither of the

contact portions

60, 62 is in contact with the lead 3R of the component 3. At this time, neither the member 3 located at the pitch adjustment position P1 nor the member 3 located at the bending position P2 is pressed against the fixed guide 46, and is aligned with the other members 3 on the conveying path TR.

As shown in fig. 14B, when the movable guide 44 advances toward the fixed guide 46 (arrow E2), the

contact portions

60, 62 move integrally, the contact portion 60 comes into contact with the lead 3R of the member 3 located at the pitch adjustment position P1, and the contact portion 62 comes into contact with the lead 3R of the member 3 located at the bending formation position P2.

As shown in fig. 8 and 9, the contact portion 60 has a pair of

claw portions

60A and 60B, and the

inclined portions

64A and 64B contact the two leads 3R from the outside at the pitch adjustment position P1, so that the pitch of the leads 3R is narrowed to a predetermined interval or less.

The contact portion 62 formed of one claw is brought into contact with the two leads 3R from the inside by the

inclined portions

66A, 66B, and thereby bends a part of the leads 3R to the outside at the bending position P2 to form a bend 3K. The member 3 located at the bending position P2 is bent 3K by the

inclined portions

66A and 66B of the contact portion 62 coming into contact with the lead 3R in a state where the main body 3B is pressed against the fixed guide 46 by the second pressing portion 86 (see fig. 13B).

As shown in fig. 11, the lead 3R of the component 3 is disposed in the

concave portions

77A, 77B of the fixed guide 46, and is pressed against the opposing

surfaces

76A, 76B by the pressing of the contact portion 62. The contact portion 62 advances toward the lead 3R in a state where the opposing

surfaces

76A, 76B are supported from the opposite sides, and the lead 3R is easily bent in the conveying direction a to form the bend 3K. As described above, since the

inclined portions

66A and 66B of the contact portion 62 have a shape in which the central portion protrudes outward, a portion of the lead 3R is easily bent to form the bent portion 3K.

As shown in fig. 11, as the movable guide 44 advances, the front end surface 68 of the contact portion 62 enters the recess 72 of the fixed guide 46, and the pair of

shutter members

74A, 74B open outward (arrows D1, D2). The

shutter members

74A and 74B are biased in the closing direction (arrows C1 and C2) in a state where the movable guide 44 is not in contact with each other, and are opened in response to contact with the contact portion 62. This ensures a wide area of the opposing

surfaces

76A, 76B for the lead 3R of the support member 3, and allows the contact portion 62 to move further inward, thereby making it easier to form the bend 3K.

By advancing the movable guide 44, as shown in fig. 15, the lead 3R of the component 3 can be processed into a desired shape at the pitch adjustment position P1 and the bending position P2, respectively. The pitch of the two leads 3R is adjusted to be equal to or smaller than a predetermined length (for example, the pitch L2) for the member 3 at the pitch adjustment position P1, and a bend 3K is formed for the two leads 3R for the member 3 at the bend formation position P2.

In the example shown in fig. 15, an intermediate position P3 is provided between the pitch adjustment position P1 and the bending formation position P2. The member 3 at the pitch adjustment position P1 is stopped at the intermediate position P3 when being conveyed by one pitch, and stopped at the bending position P2 when being conveyed by one pitch. If the intermediate position P3 is provided, the components 3 can be disposed and pitch-fed with a gap between the component holding tapes 4.

Then, when the movable guide 44 is retracted, the state shown in fig. 14A is returned. With the retraction of the movable guide 44, the main body 3B of the member 3 located at the bending position P2 is pressed by the second pressing portion 86 (see fig. 13A) in a direction away from the fixed guide 46. Thereby, the member 3 returns to the predetermined position in the conveying path TR.

The member 3 located at the pitch adjustment position P1 is slightly moved in the lateral direction B by contact with the contact portion 60, but is held between the pair of

claw portions

60A and 60B, moves integrally with the contact portion 60, and is also easily returned to its original position.

When returning to the state shown in fig. 14A, the component 3 is conveyed by the first drive source 34 by the amount of one pitch. The rear member 3 is stopped at the pitch adjustment position P1 and the bending position P2, respectively. In this state, the second driving source 48 reciprocates the movable guide 44, and thereby the same wire processing is performed on the member 3 at the pitch adjustment position P1 and the member 3 at the bending position P2, respectively.

By alternately performing the pitch feeding operation of the component 3 by the first drive source 34 and the reciprocating operation of the movable guide 44 by the second drive source 48, the bending 3K can be sequentially formed on the lead 3R of the component 3 while pitch feeding the component 3 (see fig. 15).

According to the above configuration, by using the movable guide 44 and the fixed guide 46, the bending 3K can be formed for the lead 3R of the component 3 traveling in the conveying path TR. In comparison with a structure in which a mold having a convex portion and a mold having a concave portion are fitted manually as in the prior art, the formation of the bending 3K can be automatically performed, and the supply efficiency of the component 3 can be improved.

Further, by providing the pitch adjustment position P1 on the upstream side of the bending formation position P2 and forming the bending 3K on the basis of adjusting the pitch of the lead 3R, the bending 3K can be easily formed into a desired shape.

As described above, the component supply device 13 of the embodiment includes the conveying path TR for conveying the component 3 in the conveying direction a toward the pickup position 13P, and the bending mechanism 40 for forming the bending 3K for the lead 3R of the component 3 in the conveying path TR. The bending mechanism 40 includes a movable guide 44 movable in a lateral direction B intersecting the conveying direction a, and a fixed guide 46 opposed to the movable guide 44 via a conveying path TR. The movable guide 44 has a contact portion 62 that can be brought into contact with the lead 3R of the component 3 when moving in a direction approaching the component 3, and the contact portion 62 has inclined

portions

66A and 66B that incline in a direction bending a part of the contacted lead 3R outward.

According to this configuration, the bent portion 3K can be formed on the lead 3R of the component 3 in the middle of the conveying path TR, and the supply efficiency of the component 3 can be improved as compared with a configuration in which the dies are manually fitted to each other as in the conventional apparatus.

In addition, according to the component supply device 13 of the embodiment, the fixing guide 46 has the facing

surfaces

76A, 76B facing the lead 3R of the component 3. The opposing surfaces 76A, 76B receive and support the lead 3R of the member 3 from the opposite side when the contact portion 62 of the movable guide 44 contacts the lead 3R of the member 3. According to this configuration, by bending the lead 3R in a state where the lead 3R of the member 3 is received by the opposing

surfaces

76A, 76B, the lead 3R is easily bent in a desired direction.

In addition, according to the component supply device 13 of the embodiment, the opposing

surfaces

76A, 76B have a shutter function that opens in response to contact of the movable guide 44. According to this configuration, the opposing

surfaces

76A and 76B are opened when the movable guide 44 is advanced, whereby the surface for receiving the lead 3R of the component 3 is secured, and the movable guide 44 is advanced to a deeper position, whereby the lead 3R is easily bent.

In addition, according to the component supply device 13 of the embodiment, the fixed guide 46 is biased in the direction of the

closing opposing surfaces

76A, 76B. With this configuration, when the movable guide 44 contacts and the opposing

surfaces

76A and 76B are opened, the operation can be performed with a minimum area opening.

In addition, according to the component supply device 13 of the embodiment, the movable guide 44 moves obliquely downward when approaching the component 3, and moves obliquely upward when moving away from the component 3. According to such a configuration, when the movable guide 44 contacts the lead 3R of the component 3, it is difficult to lift the component 3 upward, and the load on the component 3 can be suppressed.

In addition, according to the component supply device 13 of the embodiment, the movable guide 44 has a pressing portion (first pressing portion) 84 that presses the main body 3B of the component 3 toward the fixed guide 46 when moving in the direction approaching the component 3. With this configuration, the whole of the member 3 can be pressed against the fixed guide 46, and the bending 3K can be easily formed.

In addition, according to the component supply device 13 of the embodiment, the movable guide 44 has the pressing portion (second pressing portion) 86 that presses the main body 3B of the component 3 in the direction away from the fixed guide 46 when moving in the direction away from the component 3. With this configuration, the member 3 pushed by the fixed guide 46 can be returned to the original position.

In addition, according to the component supply device 13 of the embodiment, the movable guide 44 also has another contact portion 60 that contacts the lead 3R of the component 3 at the pitch adjustment position P1 located on the upstream side of the bending formation position P2. The other contact portion 60 has inclined

portions

64A, 64B inclined in a direction to narrow the pitch of the leads 3R of the component 3. According to this structure, by adjusting the pitch of the leads 3R on the upstream side of the bending position P2, it is easy to form the same-shape bend 3K at the bending position P2.

The component supply device 13 of the embodiment includes a first drive source 34 for performing the feeding operation of the component 3 on the transport path TR, and a second drive source 48 for driving the movable guide 44 in the lateral direction B. According to such a configuration, the feeding operation of the member 3 and the reciprocating drive of the movable guide 44 can be independently performed.

The component supply device 13 according to the embodiment further includes a control unit 16, and the control unit 16 intermittently performs the feeding operation of the component 3 by the first drive source 34 and drives the movable guide 44 by the second drive source 48 while the feeding of the component 3 by the first drive source 34 is stopped. With this configuration, unnecessary interference of the movable guide 44 with the member 3 can be prevented.

The component mounter 1 of the embodiment includes a component supply device 13 having a bending mechanism 40, and a component mounting mechanism 15. The component mounting mechanism 15 picks up the component 3 at the pickup position 13P in the component supply device 13, and inserts the lead 3R of the picked-up component 3 into the substrate 2 to mount the component 3 on the substrate 2. According to the component mounter 1 having such a structure, the same effects as those of the component supply device 13 having the bending mechanism 40 can be obtained.

In addition, the component supply method of the embodiment includes a conveying step of conveying the component 3 toward the pickup position 13P in the conveying path TR, and a bend forming step of forming a bend 3K to the lead 3R of the component 3 in the conveying path TR. In the bending step, the movable guide 44 is moved in a direction approaching the member 3 by using the bending mechanism 40 including the movable guide 44 movable in the lateral direction B intersecting the conveying direction a and the fixed guide 46 opposed to the movable guide 44 via the conveying path TR, and the

inclined portions

66A and 66B provided in the movable guide 44 are brought into contact with the lead 3R of the member 3, and a part of the contacted lead 3R is bent outward to form a bend 3K.

According to this method, the same effects as those of the component supply device 13 of the embodiment can be obtained.

The present invention has been described above by way of the embodiments described above, but the present invention is not limited to the embodiments described above. For example, in the present embodiment, the case where the pitch of the lead 3R is narrowed at the pitch adjustment position P1 and a part of the lead 3R is bent outward at the bending formation position P2 to form the bend 3K has been described, but the present invention is not limited to this case. For example, the pitch of the leads 3R may be widened at the pitch adjustment position P1, and a part of the leads 3R may be bent inward at the bending position P2 to form the bend 3K. That is, the

inclined portions

64A and 64B of the contact portion 60 may be inclined in a direction to widen or narrow the pitch of the contacted leads 3R, and the

inclined portions

66A and 66B of the contact portion 62 may be inclined in a direction to bend a part of the contacted leads 3R outward or inward.

The present invention has been fully described in connection with the preferred embodiments with reference to the accompanying drawings, but various modifications and corrections will be apparent to those skilled in the art. Such variations and modifications are to be understood as included within the scope of the present invention as defined by the appended claims. Further, the combination of elements and the change of the order of the elements of the embodiments can be realized without departing from the scope and spirit of the invention.

The above-described embodiments and any of various modifications are appropriately combined to achieve the respective effects.
