In this manner, the efficiency of supplying the components 3 by the component supply device 13 can be improved.

The configuration and operation of each of the component correction mechanisms 40 and 42 will be described below with reference to FIG. 4 and subsequent drawings.

(First component correction mechanism 40: posture correction mechanism 40A)
4 and 5 are a perspective view and a plan view of the first component correcting mechanism 40 according to the first embodiment. The first component correcting mechanism 40 of the first embodiment is a posture correcting mechanism 40A for correcting the posture of the component 3 in the middle of the transport route TR. Below, the first component correcting mechanism 40 will be described as a posture correcting mechanism 40A.

The posture correction mechanism 40A includes a movable guide 44, a fixed guide 46, a second drive source 48, and a cam mechanism 50. As shown in FIG. The movable guide 44, the fixed guide 46, the second drive source 48, and the cam mechanism 50 are all attached to the apparatus main body 43 that forms the transport path TR.

The movable guide 44 and the fixed guide 46 are members for correcting the posture of the component 3 in the conveying direction A by sandwiching the lead 3R of the component 3 therebetween.

The movable guide 44 is a guide portion configured to be movable in a lateral direction B that intersects the conveying direction A. As shown in FIG. The lateral direction B in the first embodiment is a horizontal direction orthogonal to the transport direction A and corresponds to the X-axis direction. The fixed guide 46 is arranged at a position facing the movable guide 44 across the transport path TR, and is fixed to the apparatus main body 43 .

A region between the movable guide 44 and the fixed guide 46 includes correction positions P1 and P2 for correcting the posture of the component 3. As shown in FIG. The first correction position P1 is positioned on the upstream side A1, and the second correction position P2 is positioned on the downstream side A2. After stopping at the first correction position P1, the component 3 is fed by one pitch and stops at the second correction position P2.

The movable guide 44 and the fixed guide 46 have the function of changing the inclination of the component 3 at the first correction position P1 to the front side (downstream side A2), and furthermore, change the inclination of the component 3 at the second correction position P2. It has a function to change to the rear side (upstream side A1). By changing the inclination of the part 3 to both the front side and the rear side, the part 3 is corrected toward the upright posture while considering the springback of the lead 3R regardless of whether the part 3 is tilted forward or backward. can be done. Details will be described later.

The second drive source 48 is a drive source for reciprocating the movable guide 44 in the lateral direction B. As shown in FIG. 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 along the conveying direction A. As shown in FIG. The second drive source 48 of the first embodiment is a cylinder that drives the output shaft 49 back and forth. A cam mechanism 50 is connected to the output shaft 49 of the second drive source 48 .

The cam mechanism 50 is a mechanism for converting the driving force along the conveying direction A by the second driving source 48 into the driving force in the lateral direction B and transmitting it to the movable guide 44 . The cam mechanism 50 includes a cam 54 connected to the output shaft 49 and a cam follower 56 engaged with the cam 54 and connected to the movable guide 44 . A cam groove 55 is formed at the tip of the cam 54 , and a projection 58 of a cam follower 56 is engaged with the cam groove 55 . The cam groove 55 has an oblique shape in a plan view 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. As shown in FIG. The cam follower 56 is attached to the device main body 43 in a state in which it can move in the lateral direction B, but its movement in the front-rear direction is restricted.

According to such a configuration, when the second drive source 48 drives the output shaft 49 back and forth along the conveying direction A, the cam 54 moves back and forth, and the cam follower 56 engaged with the cam 54 moves laterally. Move back and forth to B. Thereby, the movable guide 44 connected to the cam follower 56 can be reciprocated in the lateral direction B. As shown in FIG. 4 and 5 illustrate a state (during operation) in which the movable guide 44 is closest to the fixed guide 46. FIG.

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

6 and 7 are perspective views showing the movable guide 44, the fixed guide 46 and the component holding tape 4, and FIGS. 8 and 9 are plan views corresponding to FIGS. 6 and 7, respectively. 6 and 8 show a state in which the movable guide 44 approaches the fixed guide 46, and FIGS. 7 and 9 show a state in which the movable guide 44 is separated from the fixed guide 46 in an exaggerated manner. 6 to 9 omit illustration of other components including the part 3. FIG.

As shown in FIGS. 7 and 9, the movable guide 44 has two contact portions 60,62. The contact portions 60 and 62 are portions for changing the attitude of the component 3 by contacting the leads 3R of the component 3 at the correction positions P1 and P2, respectively. Both of the contact portions 60 and 62 have shapes protruding in the lateral direction B toward the fixed guide 46 in the movable guide 44 .

Concave portions 64 and 66 are formed at both ends of the fixed guide 46 . The recesses 64, 66 are recesses for accommodating one ends of the contact portions 60, 62, respectively, when the contact portions 60, 62 come closer.

As shown in FIGS. 7 and 9, the first contact portion 60 has a first inclined portion 60A and a first non-inclined portion 60B, and the second contact portion 62 has a second inclined portion 62A and a second inclined portion 62A. 2 non-inclined portions 62B.

Both the inclined portions 60A and 62A are surfaces that are inclined with respect to both the conveying direction A and the lateral direction B in plan view. Both of the non-inclined portions 60B and 62B are surfaces extending in the lateral direction B in plan view.

The first inclined portion 60A is a portion that contacts the lead 3R of the component 3 at the first correction position P1 and changes the posture of the component 3 to the front side (downstream side A2). Of the two leads 3R of the component 3, the first inclined portion 60A contacts the lead 3R on the rear side (upstream side A1). The first inclined portion 60A of Embodiment 1 has a tapered shape that is inclined in a direction away from the fixed guide 46 toward the downstream side A2 in the transport direction A. As shown in FIG.

The second inclined portion 62A is a portion that contacts the lead 3R of the component 3 at the second correction position P2 and changes the posture of the component 3 to the rear side (upstream side A1). Of the two leads 3R of the component 3, the second inclined portion 62A contacts the lead 3R on the front side (downstream side A2). The second inclined portion 62A of the first embodiment has a tapered shape that is inclined in a direction away from the fixed guide 46 toward the upstream side A1 in the transport direction A. As shown in FIG.

The first non-inclined portion 60B is a portion extending in the lateral direction B inside the first inclined portion 60A and connected to the first inclined portion 60A. The first non-inclined portion 60B receives the lead 3R of the component 3 after coming into contact with the first inclined portion 60A, and restricts movement toward the upstream side A1.

The second non-inclined portion 62B is a portion extending in the lateral direction B inside the second inclined portion 62A and connected to the second inclined portion 62A. The second non-inclined portion 62B receives the lead 3R of the component 3 after coming into contact with the second inclined portion 62A, and restricts movement toward the downstream side A2.

The movable guide 44 also has a connecting portion 68 . The connection portion 68 is a portion that connects the first non-inclined portion 60B and the second non-inclined portion 62B, and extends along the transport direction A. As shown in FIG. The connecting portion 68 is recessed inwardly with respect to the first non-inclined portion 60B and the second non-inclined portion 62B, and faces the fixed guide 46 in the lateral direction B. As shown in FIG. The connecting portion 68, together with the fixed guide 46, restricts the lateral movement of the lead 3R of the component 3 at the correction positions P1 and P2. The connection portion 68 of Embodiment 1 has a length that includes both the first correction position P1 and the second correction position P2.

10A to 10D and 11A to 11D, a method of correcting the inclination of the component 3 in the conveying direction A using the posture correcting mechanism 40A having the configuration described above will be described. 10A to 10D are diagrams for explaining the correction method when the component 3 has fallen backward, and FIGS. 11A to 11D show the correction method when the component 3 has fallen forward. It is a figure for explaining.

In the example shown in FIGS. 10A and 10B, the component 3 (illustrated by the dotted line) conveyed to the first correction position P1 falls backward (upstream side A1) with respect to the upright posture with respect to the vertical axis Q0. is in good condition. A central axis Q1 of the component 3 is inclined rearward with respect to the vertical axis Q0. In this state, when the second drive source 48 (FIGS. 4 and 5) is driven to drive the movable guide 44 in the horizontal direction B so as to approach the fixed guide 46, the first inclined portion 60A of the first contact portion 60 is moved. contacts the lead 3R on the rear side of the component 3 at the first correction position P1 (first contact step). The first inclined portion 60A is inclined away from the fixed guide 46 toward the downstream side A2 in the conveying direction A. As the movable guide 44 advances, the first inclined portion 60A moves the lead 3R to the fixed guide 46. It is biased toward the downstream side A2 while pressing. As a result, the posture of the component 3 is changed to the front side C1 (downstream side A2) (illustrated by the solid line).

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

After contacting the first inclined portion 60A, the lead 3R of the component 3 contacts the first non-inclined portion 60B inside the first inclined portion 60A shown in FIGS. When the lead 3R of the component 3 springs back and tries to return to the upstream side A1, the first non-inclined portion 60B receives the lead 3R, thereby restricting the movement to the upstream side A1.

The lead 3R of the component 3 is arranged in the region between the connecting portion 68 provided inside the first non-inclined portion 60B and the fixed guide 46. As shown in FIG. This restricts the lateral movement of the lead 3R in the B direction.

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

In the first embodiment, in consideration of the springback of the leads 3R, the component 3 is in an approximately upright posture after the springback, and the first inclined portion 60A moves the component 3 so that the central axis Q3 approximately coincides with the vertical axis Q0. A target posture is set for correcting the posture.

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

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

As for the second correction position P2, considering the springback of the lead 3R of the component 3, the target posture of the component 3 after posture correction by the second inclined portion 62A is set so that the central axis Q4 of the component 3 is positioned above the vertical axis Q0. It is set at a position inclined to the rear side C2.

After that, when the movable guide 44 is retracted, as shown in FIGS. 10C and 10D, when the part 3 is tilted slightly rearward with respect to the vertical axis Q0 (illustrated by the dotted line), the lead 3R of the part 3 is pulled by the spring. The inclination of the part 3 is naturally changed to the front side C4 (downstream side A2) by the back movement (illustrated by the solid line). As in the first correction position P1, the component 3 after springback is in a substantially upright posture, and the central axis Q5 of the component 3 substantially coincides with the vertical axis Q0.

As described above, the part 3 corrected to the upright posture at the first correction position P1 is again corrected toward the upright posture at the second correction position P2. In this way, when the component 3 sent to the first correction position P1 is tilted backward (upstream side A1), the posture of the component 3 is corrected in two steps using the posture correction mechanism 40A. and corrects the part 3 to an upright posture.

Next, a posture correcting method when the component 3 is tilted forward (downstream side B2) will be described with reference to FIGS. 11A to 11D.

In the example shown in FIGS. 11A and 11B, the component 3 (illustrated by the solid line) conveyed to the first correction position P1 falls forward (downstream side A2) with respect to the upright posture with respect to the vertical axis Q0. is in good condition. A central axis Q6 of the component 3 is inclined forward with respect to the vertical axis Q0. In this state, when the second drive source 48 (FIGS. 4 and 5) is driven to drive the movable guide 44 in the horizontal direction B so as to approach the fixed guide 46, the part 3 is moved as shown in FIGS. 11A and 11B. is greatly tilted forward, the first inclined portion 60A of the first contact portion 60 does not contact the lead 3R on the rear side of the component 3 and does not correct the posture of the component 3 (arrow C1). In this case, even if the movable guide 44 is retracted, the leads 3R of the component 3 do not spring back, so the posture of the component 3 is maintained tilted forward as shown in FIGS. 11C and 11D.

On the other hand, when the inclination of the component 3 is small, when the movable guide 44 approaches the fixed guide 46, the first inclined portion 60A becomes the lead on the rear side of the component 3 as in the case shown in FIGS. 10A to 10D. By contacting 3R, the posture of the component 3 is corrected to the front side C1.

The part 3 whose posture has not been corrected at the first correction position P1 is then sent to the second correction position P2. As shown in FIGS. 11A and 11B, when the component 3 stopped at the second correction position P2 is greatly tilted forward (indicated by a dotted line), the movable guide 44 is moved to the fixed guide 46 by the second drive source 48 described above. , the second inclined portion 62A of the second contact portion 62 contacts the lead 3R on the front side of the component 3. As shown in FIG. As a result, the posture of the component 3 is changed to the rear side C5 (upstream side A1) (illustrated by the solid line).

10A to 10D, the target posture of the component 3 after posture correction by the second inclined portion 62A is determined by considering the springback of the lead 3R of the component 3 so that the central axis Q7 of the component 3 is It is set to incline to the rear side C5 with respect to the vertical axis Q0. After that, when the movable guide 44 is retracted, as shown in FIGS. 11C and 11D, springback occurs in the leads 3R of the component 3, and the attitude of the component 3 is naturally changed to the forward side C6 (downstream side A2). (illustrated by solid lines).

As described above, even when the component 3 is tilted forward, the posture correction mechanism 40A can be used to correct the component 3 toward the upright posture. In this case, when the inclination of the component 3 is large, it is corrected to the upright posture at the second correction position P2 without being corrected to the upright posture at the first correction position P1. When the inclination of the 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 manner, the posture of the component 3 can be corrected toward the upright posture as in the case where the component 3 is tilted backward.

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

After that, the posture correction by the posture correction mechanism 40A is performed on the parts 3 that are successively stopped at the correction positions P1 and P2. As a result, the posture of the component 3 can be uniformly corrected on the way to the pickup position 13P, and the posture of the component 3 reaching the pickup position 13P can be stabilized. In this way, the success rate when the component mounting mechanism 15 picks up the component 3 at the pickup position 13P can be improved, and the efficiency of supplying the component 3 by the component supply device 13 can be improved.

The second component correcting mechanism 42 of the first embodiment is a posture correcting mechanism 42A for correcting the posture of the component 3 at the pick-up position 13P. Below, the 2nd component correction mechanism 42 is demonstrated as 42 A of attitude|position correction mechanisms.

As described above, the posture of the component 3 is temporarily corrected on the upstream side A1 of the pickup position 13P using the posture correction mechanism 40A. The component supply device 13 of Embodiment 1 further includes an attitude correction mechanism 42A at the pickup position 13P in order to hold the component 3 at the pickup position 13P in an upright posture with higher accuracy.

As will be described later, the component supply device 13 of the first embodiment cuts the leads 3R of the component 3 at the pick-up position 13P, so the posture of the component 3 tends to change at the pick-up position 13P. In response to this, in the component supply device 13 of the present embodiment, the posture correcting mechanism 42A is provided at the pickup position 13P, and the lead 3R is cut while the component 3 is held in the upright posture. As a result, the posture of the component 3 can be stabilized even after the cutting operation.

The posture correcting mechanism 42A shown in FIGS. 12 to 14 includes a first restricting portion 100, a second restricting portion 102, a first driving source 34, a cam mechanism 106, and a lead cutting portion 107. As shown in FIG. The first restricting portion 100, the second restricting portion 102, the first driving source 34, the cam mechanism 106, and the lead cutting portion 107 are all attached to the device main body portion 43 that forms the transport path TR.

The first restricting portion 100 and the second restricting portion 102 are members for restricting the movement of the component 3 at the pick-up position 13P and holding the posture of the component 3 in an upright posture. Specific configurations of the first restricting portion 100 and the second restricting portion 102 will be described later. has a function of restricting movement of the component 3 in the forward and backward direction along the conveying direction A. As shown in FIG.

By providing the first restricting portion 100 and the second restricting portion 102, it is possible to restrict the movement of the component 3 in the horizontal direction (in the XY-axis direction) and to accurately hold the component 3 at the pickup position 13P in an upright posture. can. As a result, the lead 3R can be cut while the posture of the component 3 is maintained.

In the posture correcting mechanism 42A of Embodiment 1, the first restricting portion 100 is fixed to the device body portion 43, and the second restricting portion 102 is attached to the device body portion 43 so as to be movable in the lateral direction B. As shown in FIG. The second restricting portion 102 is driven by a first drive source 34 (FIG. 12) for feeding the component 3 .

The first drive source 34 is a drive source for pitch-feeding the component holding tape 4 shown in FIG. The output shaft 35 of the first drive source 34 is connected to the cam mechanism 106 .

The cam mechanism 106 is a mechanism for converting the driving force along the conveying direction A of the first driving source 34 into the driving force in the horizontal direction B and transmitting it to the second restricting portion 102 . The cam mechanism 106 includes a cam 108 connected to the output shaft 35 and a cam follower 110 engaged with the cam 108 and connected to the second restricting portion 102 . A cam groove 109 is formed in the cam 108 , and a projection 111 of a cam follower 110 engages with the cam groove 109 . The cam groove 109 has an oblique shape in a plan view such that the cam follower 110 moves along the lateral direction B when the cam 108 moves back and forth along the conveying direction A. The cam follower 110 is attached to the device main body 43 in a state in which it can move in the lateral direction B but its movement in the front-rear direction is restricted.

According to such a configuration, when 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 moves in the lateral direction B. move back and forth to Thereby, the second restricting portion 102 connected to the cam follower 110 can be reciprocated in the lateral direction B. As shown in FIG. The second restricting portion 102 reciprocates between a restricting position that restricts movement of the component 3 and a retracted position that retracts from the component 3 . 12 to 14 illustrate the state (during operation) in which the second restricting portion 102 is in the restricting position.

The lead cutting part 107 is a member for cutting the lead 3R of the component 3 at the pickup position 13P. By cutting the lead 3R of the component 3 at the pickup position 13P, the length of the lead 3R is previously adjusted to a desired length.

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

As shown in FIGS. 12 to 14, a transport chute 112 is provided on the downstream side A2 of the pickup position 13P. The transport chute 112 is a member for transporting the component holding tape 4 further downstream from the pickup position 13P. Since the component 3 is picked up at the pickup position 13P, the component holding tape 4 transported to the transport chute 112 does not normally hold the component 3 . Exceptionally, when the operator OP manually feeds the component holding tape 4 to the downstream side A2 while the operation of the component supply device 13 is stopped, the component holding tape 4 conveyed to the conveying chute 112 does not have the component 3 thereon. may be retained.

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

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

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

The second restricting portion 102 includes a front guide portion 116 and a rear guide portion 118 . The guide portions 116 and 118 are members that sandwich the component 3 at the pick-up position 13P in the front-rear direction and restrict movement thereof. The front guide portion 116 is arranged in front of the pickup position 13P (downstream side A2), and the rear guide portion 118 is arranged behind the pickup position 13P (upstream side A1).

Both the front guide portion 116 and the rear guide portion 118 are connected to the cam follower 110 described above and move along the lateral direction B integrally. 12 to 14, FIGS. 15 to 17 illustrate states in which the front guide portion 116 and the rear guide portion 118 are in restricting positions for restricting movement of the component 3. FIGS.

The front guide portion 116 of Embodiment 1 has an L-shaped shape in plan view. The front guide portion 116 extends downstream A2 in the transport direction A, then bends at a substantially right angle, and extends along the lateral direction B. As shown in FIG. A tip side portion of the front guide portion 116 extending along the lateral direction B is arranged so as to block the front of the component 3, and restricts the movement of the component 3 to the downstream side A2.

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

The fixed portion 120 is a plate-like member that is fixed to the cam follower 110 . The rotating portion 122 is a plate-like member that is connected to the fixed portion 120 and configured to be rotatable about the rotation axis X1. The rotating part 122 has a function of preventing interference with the part 3 by rotating around the rotation axis X<b>1 when coming into contact with the part 3 moving forward along the conveying direction A.

The pressing portion 124 is an urging member that urges the rotating portion 122 in a rotational direction opposite to the rotational force that causes the rotating portion 122 to rotate forward (downstream side A2). By providing the holding portion 124, the rotating portion 122 can be prevented from rotating vigorously forward due to contact with the component 3, and the operation of the rotating portion 122 can be stabilized.

Here, functions and operations of the rear guide portion 118 will be described with reference to FIGS. 18A and 18B. 18A is a side view showing a state in which the component 3 is not in contact with the rotating portion 122, and FIG. 18B is a side view showing a state in which the component 3 is in contact with the rotating portion 122 and the rotating portion 122 is rotated. .

As shown in FIG. 18A , the rotating portion 122 extends vertically downward when the component 3 does not come into contact with the rotating portion 122 . At this time, the distal end 110A of the cam follower 110 abuts on the root portion of the rotating portion 122, so that the rotating portion 122 is restricted from rotating upstream A1 (arrow R1). While the rotating part 122 can rotate downstream A2 (arrow R2), the pressing part 124 contacts the rotating part 122 and urges it in the opposite direction (arrow R3), so that the rotating part 122 rotates. resistance occurs.

As shown in FIG. 18B, when the component 3 is transported in the transport direction A and contacts the rotating part 122, the rotating part 122 rotates downstream A2 around the rotation axis X1 due to contact with the side surface of the component 3 ( Arrow R2). Interference with the component 3 can be prevented by rotating the rotating part 122 .

When the rotating part 122 rotates, the pressing part 124 urges the rotating part 122 in the opposite direction (arrow R3), so the rotating part 122 does not rotate vigorously and maintains contact with the side surface of the component 3. Rotate slowly while As a result, the rotating part 122 does not collide with the part 3 (not shown) in front of the part 3 shown in FIG.

The operation of the posture correcting mechanism 42A having the configuration described above will be described with reference to FIG. 19 and subsequent figures.

FIG. 19 is a plan view of the case where the first drive source 34 having the output shaft 35 is used to reciprocate the second restricting portion 102 in the lateral direction B. FIG. In FIG. 19, (a) corresponds to the state in which the second restricting portion 102 is in the restricting position, and (b) corresponds to the state in which the second restricting portion 102 is in the retracted position.

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

As shown in FIG. 19B, when the first drive source 34 drives the output shaft 35 to move the cam 108 of the cam mechanism 106 to the upstream side A1, the projection of the cam follower 110 moves along the cam groove 109. 111 moves in the horizontal direction B, and the cam follower 110 moves toward the right side of the drawing. The second restricting portion 102 connected to the cam follower 110 also moves toward the right side of the drawing and moves to the retracted position retracted from the component 3 at the pick-up position 13P.

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

Particularly in the first embodiment, the common first drive source 34 is used to perform pitch feeding of the component 3 and drive of the second restricting portion 102 . Therefore, by providing the rotating portion 122 in the rear guide portion 118 to prevent interference between the feeding operation of the component 3 and the rear guide portion 118, the pitch feeding of the component 3 and the driving of the second restricting portion 102 can be performed in parallel. can be executed.

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

As shown in FIG. 20, the component holding tape 4 has a plurality of feed holes 126 for pitch feeding. A pawl (not shown) connected to the first drive source 34 is engaged with the feed hole 126 .

When the first drive source 34 drives the pawl toward the downstream side A2, the pawl is engaged with the feed hole 126, and the component holding tape 4 is advanced by one pitch. On the other hand, when the first drive source 34 drives the pawl to the upstream side A1, the engagement between the pawl and the feed hole 126 is released, so the component holding tape 4 does not retreat and remains stationary. The component holding tape 4 is pitch-fed along the conveying direction A by reciprocating the claw portion with the first drive source 34 at a predetermined cycle, and the component 3 is intermittently fed.

Especially in Embodiment 1, a large radial component is handled as the component 3 . As shown in FIG. 20, the pitch Y2 of the parts 3 is set longer than the pitch Y1 of the feed holes 126 (twice in the first embodiment). When the first drive source 34 performs two reciprocating motions, the component holding tape 4 is sent to the downstream side A2 of two pitches (Y1×2) of the feed holes 126, and the component 3 is sent to the downstream side of one pitch (Y2). Sent to A2.

When the first driving source 34 is driven for two reciprocating motions, the part 3 is fed by one pitch, whereas the reciprocating motion of the second restricting portion 102 by the same first driving source 34 makes two reciprocating motions in the horizontal direction B. . That is, when the component 3 is fed by 0.5 pitches, the second restricting portion 102 makes one reciprocation in the lateral direction B. Therefore, the second restricting portion 102 does not guide the component 3 in front of the pick-up position 13P. Portions 118 come into contact.

In response to this, the posture correcting mechanism 42A of the first embodiment provides the rotating portion 122 described above in the rear guide portion 118, and rotates when the rotating portion 122 contacts the side surface of the component 3 in front of the pickup position 13P. I am making it possible. As a result, when the same first driving source 34 is used to perform the feeding operation of the component 3 and the reciprocating operation of the second restricting portion 102, both operations can be performed in parallel while preventing interference between the component 3 and the second restricting portion 102. can be run as

A specific operation of the posture correcting mechanism 42A having the configuration described above will be described with reference to FIGS. 21A to 24B.

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

As shown in FIGS. 21A and 21B, the first restricting part 100 already restricts movement in the lateral direction B from the part 3 positioned behind the pickup position 13P. On the other hand, the second restricting portion 102 is at the retracted position and does not restrict the movement of the component 3 .

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

As shown in FIGS. 22A and 22B, the component 3 is sent downstream A2 by 0.5 pitches (conveying step), and the second restricting portion 102 is moved in the lateral direction B so as to approach the conveying route TR. .

Since the component 3 is in front of the pick-up position 13P, when the rotating portion 122 of the second restricting portion 102 moves in the lateral direction B, it contacts the side surface of the component 3. As shown in FIG. The contact with the part 3 causes the rotating part 122 to rotate toward the downstream side A2 (arrow R2 in FIG. 22A). This prevents interference between the rear guide portion 118 and the component 3 . At this time, since the rotating part 122 rotates while being urged in the opposite direction by the pressing part 124, it does not rotate vigorously toward the downstream side A2, but rotates slowly while maintaining contact with the side surface of the component 3. . Thereby, the rotation operation of the rotating portion 122 can be stabilized.

In this way, even when the part 3 moves forward by 0.5 pitches due to one reciprocating drive of the first drive source 34, the part 3 is prevented from interfering with the rear guide portion 118 and the part 3. The feeding operation and the reciprocating operation of the second restricting portion 102 can be executed in parallel.

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

As shown in FIGS. 23A and 23B, the component 3 remains stationary without moving, and the second restricting portion 102 moves in the lateral direction B away from the transport path TR and moves to the retracted position. . The rotating portion 122, which has been released from contact with the component 3, returns to a vertically downwardly extending state.

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

As shown in FIGS. 24A and 24B, the component 3 is sent to the downstream side A2 by 0.5 pitches and reaches the pick-up position 13P. When the second restricting portion 102 moves in the lateral direction B so as to approach the transport path TR, the rotating portion 122 does not contact the component 3 because the component 3 has moved to the pickup position 13P. The rotating part 122 enters the area between the part 3 at the pick-up position 13P and the part 3 in front of it.

As described with reference to FIG. 18A , rotation of rotating portion 122 toward upstream side A1 is restricted by distal end 110A of cam follower 110, and movement of component 3 toward upstream side A1 is restricted. As a result, the component 3 at the pick-up position 13P is sandwiched between the front guide portion 116 and the rear guide portion 118 in the front-rear direction, and movement in the front-rear direction is restricted.

In the state shown in FIGS. 24A and 24B, the first restricting portion 100 restricts the movement in the lateral direction B of the part 3 at the pickup position 13P (first restricting step), and the second restricting portion 102 moves in the conveying direction A. movement in the front-rear direction along the line is regulated (second regulating step). As a result, the horizontal movement of the component 3 is restricted, and the component 3 can be held in an upright posture with high accuracy.

After that, the leads 3R are cut by the lead cutting section 107 for the component 3 at the pick-up position 13P. Specifically, the movable portion 107B approaches the fixed portion 107A and sandwiches the lead 3R of the component 3, thereby cutting the lead 3R.

The cutting operation of the lead 3R by the lead cutting section 107 is performed in a state where the horizontal movement of the component 3 is restricted by the first restricting section 100 and the second restricting section 102 . As a result, it is possible to prevent the posture of the component 3 from collapsing due to the cutting operation of the leads 3R, and to maintain the upright posture of the component 3 with high accuracy.

The component 3 from which the lead 3R has been cut is picked up by the component mounting mechanism 15 shown in FIG. The component mounting mechanism 15 lowers the mounting head 22 positioned above the pick-up position 13P to bring the suction nozzle 22a of the mounting head 22 into contact with the upper surface of the body 3B of the component 3 to pick up the component 3. As a result, the component 3 at the pickup position 13P is picked up, and the component supply device 13 supplies the component 3. As shown in FIG.

After picking up the component 3, the component mounting mechanism 15 inserts the lead 3R of the component 3 into the insertion hole of the board 2 and mounts it on the board 2. - 特許庁

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

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

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

The first inclined portion 214A contacts the lead 3R on the rear side (upstream side A1) of the two leads 3R of the component 3 at the pitch adjustment position P3. 214 A of 1st inclination parts of Embodiment 1 have the taper shape inclined in the direction away from the fixed guide 202, so that it goes to downstream A2 of the conveyance direction A.

FIG. 31 shows the movable guide 200 and the fixed guide 202 independently, and FIG. 32 shows a state in which the movable guide 200 approaches the fixed guide 202. FIG. 33 is a diagram showing the stopper 204 alone, FIG. 34 is a diagram showing the fixed guide 202, the stopper 204, and the component 3 held by the component holding tape 4, and FIG. 35 is a diagram showing FIG. It is the figure which added the movable guide 200 in addition to the structure.

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

By sandwiching the body 3B of the component 3 between the facing surface 220 and the facing surface 225, as shown in FIGS. 34 and 35, movement in the lateral direction B of the component 3 located at the pitch adjustment position P3 is restricted.

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

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

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

As shown in FIG. 36A, the component holding tape 4 (not shown) is fed in the transport direction A (transport step), and the new component 3 stops at the pitch adjustment position P3. As the component 3 stops, the movable guide 200 is driven in the lateral direction B (arrow F1), and the contact portions 214 and 216 move forward toward the two leads 3R of the component 3 at the pitch adjustment position P3. In the example shown in FIG. 36A, the pitch of the two leads 3R is length D2.

When the movable guide 200 advances, as shown in FIG. 36B, the first contact portion 214 contacts the lead 3R on the rear side of the component 3, and the second contact portion 216 contacts the lead 3R on the front side of the component 3. (first contact step). The portion of the first contact portion 214 that starts contacting the lead 3R of the component 3 is the first inclined portion 214A, and the portion of the second contact portion 216 that starts contacting the lead 3R of the component 3 is the second inclined portion. 216A.

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

As the movable guide 200 moves further forward, the two leads 3R cross over the inclined portions 214A and 216A and contact the non-inclined portions 214B and 216B as shown in FIG. 36C (second contact step). Since the non-inclined portions 214B and 216B have a shape in which the interval in the transport direction A is kept constant, a pressing force is applied to the two leads 3R in the direction of narrowing the pitch even while the movable guide 200 is moving forward. (Arrow F4). At this time, the pitch of the leads 3R is temporarily narrowed to the interval D1 between the non-inclined portions 214B and 216B.

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

When movable guide 200 is retracted in lateral direction B from the state shown in FIG. 36C (arrow F5), as shown in FIG. Contact with lead 3R is released.

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

After that, the component holding tape 4 is fed in the conveying direction A, and the next component 3 stops at the pitch adjustment position P3. By reciprocating the movable guide 200 with respect to the next component 3 as well, the pitch of the leads 3R can be adjusted to a desired length. In this way, it is possible to adjust the pitch of the leads 3R for each of the components 3 conveyed on the conveying route TR.

Each component 3 is conveyed toward the pick-up position 13P with the leads 3R having a desired pitch. As a result, when the component mounting mechanism 15 picks up the component 3 and inserts the leads 3R of the component 3 into the insertion holes of the substrate 2, it is possible to insert the component 3 with high precision, thereby preventing the occurrence of errors due to the pitch of the leads 3R. can be reduced. In this manner, the efficiency of supplying the components 3 by the component supply device 13 can be improved.

(Actions and Effects Related to Lead Pitch Adjustment Mechanism 40B)
As described above, the component supply device 13 of the first embodiment includes a transport route TR that transports the component 3 toward the pickup position 13P in the transport direction A, and a lead that adjusts the pitch of the lead 3R of the component 3 in the transport route TR. and a pitch adjustment mechanism 40B. The lead pitch adjustment mechanism 40B includes a movable guide 200 that can move in a lateral direction B that intersects the transport direction A, and a fixed guide 202 that is provided at a position facing the movable guide 200 with the component 3 interposed therebetween. The movable guide 200 has contact portions 214 and 216 that can come into contact with the two leads 3R of the component 3 when it moves toward the component 3 . The contact portions 214 and 216 have inclined portions 214A and 216A that are inclined in the direction of narrowing the pitch of the two leads 3R.

According to such a configuration, by bringing the contact portions 214 and 216 of the movable guide 200 into contact with the leads 3R on the transport route TR along which the two leads 3R are transported with a gap in the transport direction A, The pitch of the leads 3R can be adjusted. As a result, the pitch of the leads 3R can be adjusted in the transport route TR, and the efficiency of supplying the components 3 by the component supply device 13 can be improved.

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

As shown in FIG. 43A, when the pusher 300 is in the retracted position (during non-operation), the component holding tape 4 is pitch-fed in the transport direction A (transport step), and one component 3 (illustrated by the dotted line) is It stops at the correction position P4. As the component 3 stops, the second drive source 306 (FIGS. 37 and 38) drives the pusher 300 to advance in the pressing direction G1.

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

As shown in FIG. 43B, the pressing surface 314 of the pusher 300 contacts the pressed portions 334 and 338 of the levers 316 and 318 and presses them in the pressing direction G1. Each of the levers 316 and 318 rotates, the first lever 316 rotates about the first rotation shaft 317 in the rotation direction R8, and the second lever 318 rotates about the second rotation shaft 319 in the rotation direction R9. (part straightening step).

As the first lever 316 rotates, the first restricting portion 336 faces the lead 3R on the rear side (upstream side A1) of the component 3 in the first pressing direction H1. The first pressing direction H1 is a direction toward the downstream side A2 in the transport direction A. As shown in FIG. In the example shown in FIG. 43B, the first restricting portion 336 contacts the lead 3R of the component 3 and presses it in the first pressing direction H1. The lead 3R of the component 3 pressed in the first pressing direction H1 is pressed toward the first opposing surface 330 of the pusher 300 that has moved forward. As a result, the rear lead 3R is positioned in the gap between the first restricting portion 336 and the first opposing surface 330, and is restricted from moving forward and backward along the transport direction A (first lead correcting step).

The lead 3R is also sandwiched between the third facing surface 332 of the advanced pusher 300 and the first lead facing portion 344 of the first pusher 322 . As a result, the lateral movement of the leads 3R on the rear side is also restricted. In this way, the horizontal movement of the lead 3R is restricted.

The first restricting portion 336 of the first lever 316 that rotates in the rotation direction R8 contacts the first lead facing portion 344 of the first stopper 322 and is restricted from further rotation. The first lead facing portion 344 also functions as a stopper for the first lever 316 .

As the second lever 318 rotates, the second restricting portion 340 faces the lead 3R on the front side (downstream side A2) of the component 3 in the second pressing direction H2. The second pressing direction H2 is the direction toward the upstream side A1 in the transport direction A. As shown in FIG. In the example shown in FIG. 43B, the second restricting portion 340 contacts the lead 3R of the component 3 and presses it in the second pressing direction H2. The lead 3R of the component 3 pressed in the second pressing direction H2 is pressed toward the second facing surface 331 of the pusher 300 that has moved forward. As a result, the lead 3R on the front side is positioned in the gap between the second restricting portion 340 and the second facing surface 331, and movement in the front-rear direction along the transport direction A is restricted (second lead correcting step).

The lead 3R is further sandwiched between the fourth facing surface 333 of the advanced pusher 300 and the second lead facing portion 348 of the second pusher 324 . As a result, the lateral movement of the lead 3R on the front side is also restricted. In this way, the horizontal movement of the lead 3R is restricted.

The second restricting portion 340 of the second lever 318 rotating in the rotation direction R9 contacts the second lead facing portion 348 of the second stopper 324 and is restricted from further rotation. The second lead facing portion 348 also functions as a stopper for the second lever 318 .

In the state shown in FIG. 43B, the two leads 3R are positioned at respective predetermined positions, so that the pitch of the leads 3R is adjusted to a desired length and the posture of the component 3 is corrected. In the state before adjustment shown in FIG. 43A, if the pitch of the two leads 3R is wider than the desired pitch length, as shown in FIG. By pressing in the direction, the pitch of the leads 3R is narrowed. At the same time, if the two leads 3R are inclined with respect to the vertical direction (Z-axis direction), the component 3 is corrected toward the upright posture.

After that, when the pusher 300 is driven in the retreating direction G2 opposite to the pressing direction G1, the same state as shown in FIG. 43A is restored. Springback occurs in the leads 3R, but the pitch of the leads 3R approaches the desired pitch length and the posture of the component 3 approaches the upright posture compared to the state before the pusher 300 is operated.

After that, the component holding tape 4 is fed in the conveying direction A, and the next component 3 is stopped at the correction position P4. By reciprocating the pusher 300 with respect to the next component 3 as well, the pitch of the leads 3R can be adjusted to a desired length, and tilting of the component 3 can be corrected. In this manner, pitch adjustment of the leads 3R and tilt correction of the component 3 can be performed for each of the components 3 transported on the transport path TR.

Each component 3 is conveyed toward the pick-up position 13P with the leads 3R having a desired pitch. As a result, when the component mounting mechanism 15 picks up the component 3 and inserts the leads 3R of the component 3 into the insertion holes of the substrate 2, it is possible to insert the component 3 with high precision, thereby preventing the occurrence of errors due to the pitch of the leads 3R. can be reduced. In addition, since each component 3 is conveyed toward the pick-up position 13P while being maintained in a substantially upright posture, the pick-up success rate of the component 3 by the component mounter 15 is improved. In this manner, the efficiency of supplying the components 3 by the component supply device 13 can be improved.

In the example shown in FIGS. 43A and 43B, the case where the pitch of the two leads 3R is wide before the pusher 300 operates and the pitch of the leads 3R is narrowed has been described. It is also possible to adjust so as to widen the pitch of the leads 3R. For example, in the state before adjustment shown in FIG. 43A , if the pitch between the two leads 3R is narrow, the two leads 3R come into contact with the inclined surfaces 326 and 328 as the pusher 300 advances. The leads 3R on the rear side contact the first inclined surface 326, and the leads 3R on the front side contact the second inclined surface 328. As shown in FIG. Depending on the inclination direction of each 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 toward the second opposing surface 331. directed outward (downstream side A2). As a result, the pitch between the two leads 3R is widened, and the leads 3R are positioned at predetermined positions as in the case shown in FIG. 43B. In this manner, even if the pitch of the leads 3R is narrow, by using the inclined surfaces 326 and 328, the pitch of the leads 3R can be widened and the posture of the component 3 can be corrected.
