The bending mechanism is actuated via the switching mechanism, and the bending mechanism bends the lead wire of the continuous cut piece of the axial electronic component into a radial shape and transfers it to the chuck. It is an object of the present invention to provide an electronic component transfer device that also makes it possible to insert axial electronic components using an automatic insertion device.

Embodiments of the electronic component transfer device according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a state in which an electronic component transfer device using a pallet for electronic component transfer is incorporated into an automatic insertion device. In this figure, electronic component transfer device 1
has an intermittent running endless belt mechanism in which a chain is stretched between sprockets 2A to 2D, and pallets 4 for transferring electronic components that can be used for both axial and radial components are fixed at equal intervals on this chain. There is. Each pallet 4 holds a series of axial or radial electronic component pieces obtained by cutting a series of axial or radial electronic components into pieces each having one electronic component. The supply parts 5 are arranged at equal intervals to the pallets 4 along the linear running part of the chain, that is, the straight running part of the pallets 4,
Each supply section 5 is connected to an axial or radial electronic component string pulled out from a package 6 rotatably housing a reel wound with the electronic component string. In this case, the package 6 is also arranged at the same spacing as the supply section 5, and the axial or radial electronic component series pulled out from the package 6 are drawn out to the supply section 5 as they are without twisting or the like. At this time, the drawer length of the electronic component series is 6 for each package cage.
The same is true for

The automatic insertion device includes, in addition to the electronic component transfer device 1, a chuck 10 that clamps the radial lead wire of the continuously cut electronic component piece transferred by the device, and a rotary disk 11 on which the chucks 10 are provided at equal intervals. Lead wires of electronic components transported by chuck 10
It includes an insertion section 13 that is inserted into the printed circuit board on the XY table 12.

The electronic component transfer device 1 is a folding device that bends a pallet 4 and the lead wires of continuous cut pieces of axial electronic components transferred by the pallet 4 into a radial shape and transfers them to a chuck 10 located along the pallet travel path. It is equipped with a bending mechanism and a switching mechanism that switches the operation between when the pallet supports the continuous cut pieces of axial electronic components and when the pallet holds the continuous cut pieces of radial electronic components. This is shown in FIGS. 2 to 16.

In FIGS. 2 to 8, a pallet 4 for transferring electronic components that can be used for both axial and radial parts is fixed to the chain 3 at a pallet body 20, and hinges projecting from the side of the pallet body 20. A component holding portion 22 for holding a radial electronic component is pivotally attached to the portion 21 by a pin 23. The component holding section 22 is provided with a holding claw 24, and the holding claw 24 is urged by a spring 25 so as to come into pressure contact with the upper surface of the component holding section 22. Further, a slide bar 26 having a shape shown in FIG. 6 is slidably passed through the pallet main body 20.
The component holding portion 2 is inserted into the groove 27 at the tip of the slide bar 26.
A pin 28 protruding from the lower surface of 2 engages with the pin 28. An extension spring 30 is provided between the pin 29 at the rear end of the slide bar 26 and the pallet body 20, and as a result, the slide bar 26 is in a state of protruding forward, that is, the component holding portion 22 is not attached to the pallet body 20. It is kept in a parallel drawn state.
When a command is given to supply radial electronic components to the pallet 4, in this state, the radial electronic component chain 7 is cut into one electronic component as shown by the dashed line A in FIG. The operation of supplying the continuous cut pieces 40 onto the component holding section 22 is performed by the radial supply section 5 shown in FIG.

Furthermore, as shown in FIG. 7, a component receiving jig 32 for receiving axial electronic components is fixed on the pallet body 20 via a pedestal 31. The component receiving jig 32 has a pair of elastic arms 34 having a V-shaped lead engagement groove 33 formed at the tip thereof.
When the supply of axial electronic components is instructed, the axial electronic component chain 35 in the state shown in FIG. 3 is cut to have one electronic component as shown by the dashed line B in FIG. The operation of supplying the cut piece 36 onto the component receiving jig 32 is performed by the axial supply section 5 shown in FIG. In this feeding operation, as shown in FIG. 3, the tip of the elastic arm 34 is accurately positioned by a guide 37 on the feeding section side, thereby correcting the positional shift of the pallet 4 due to chain drive.

Now, the pallet 4 for transferring electronic parts is in the state shown in FIG. 2 or 3 during normal travel, but
Sprocket 2 with chucks 10 closely facing each other
When the pallet 4 travels in an arc along the path C, the component holding portion 22 of the pallet 4 rotates as shown in FIG. It is designed to be able to be transported in a fixed position. A mechanism for this is provided radially on the sprocket 2C, and as the sprocket 2C rotates, a hook 46 that engages with a groove 60 at the rear end of the slide bar 26 pulls the slide bar 26 toward the center to remove the parts. Holding part 22
is rotated until it reaches a position protruding perpendicularly to the side of the pallet body 20.

On the other hand, when the pallet 4 is transporting the continuous cut pieces 36 of axial electronic components, the component holder 22 returns to its original position when it comes to a position facing the chuck 10, as shown in FIG. Details of the switching mechanism for this purpose and the bending mechanism for bending the lead wire of the axial electronic component continuous cut piece 36 into a radial shape and transferring it to the chuck 10 are shown in FIGS. 8 to 16. In these figures, a cam 41 is fixedly supported by a cam support member 42 concentrically with the sprocket 2C, and fixed blocks 43 are fixed radially on the sprocket 2C at equal angular intervals. A cam follower 44 is provided so as to slidably pass through it. And cam follower 44
The hook 46, which can engage with the groove 60 at the rear end of the slide bar 26, is attached to the tip of the slide bar 26. A roller 49 is provided at the rear end of the cam follower 44 so that it can come into contact with the cam 41. An extension spring 50 is provided between the cam follower 44 and the fixed block 43. This extension spring 50 is sufficiently stronger than the extension spring 30 on the pallet 4 side, so that the cam follower 44 is normally urged in a direction in which it comes into pressure contact with the cam 41.

On the other hand, although not shown in FIG. 1, a support plate 70 is horizontally fixed to the main frame at a position above the sprocket 2C as shown in FIG. is fixed, and a horizontal slider 72 is slidably attached to the horizontal slider 72.
An L-shaped roller contact plate 73 is fixed to the slider 72. This roller abutment plate 73 is used only when inserting axial parts into the shaft 74 erected on the cam follower 44.
It can come into contact with a roller 75 provided in the. However, the roller contact plate 73 contacts the roller 75 only with respect to the cam follower 44 that drives the pallet 4 that is in front of the chuck 10 located along the pallet travel path. Further, a support block 80 is fixed to the tip of the support plate 70, and a vertical slider 81 is provided to support the support block 80 so as to be slidable in the vertical direction.

As shown in FIG. 8, the vertical slider 81 moves up and down almost directly above the chuck 10, which is located along the pallet travel path.

As shown in FIGS. 11 to 16, a bending mechanism 85 consisting of a lower die 82, an upper die 83, and a horizontal die 84 is pivotally attached to the lower end of the vertical slider 81 by a pin 86. As shown in FIG. 11, the lower mold 82, the upper mold 83, and the horizontal mold 84 are commonly pivotally connected to the vertical slider 81 by pins 86, and the lower mold 82 is connected to the horizontal mold 84.
4 is pushed up by a compression spring 88 provided at the bottom connecting portion 87. The amount of push-up in this case is regulated by a stopper 89 formed on the lower die 82 coming into contact with the right side surface of the bottom connecting portion 87 . The lower mold 82 is formed with a main body holding groove 90 for holding the electronic component main body 36A of the axial electronic component cut piece 36, and the upper mold 83 has protrusions 91 at both ends that hold down the bases of the lead wires of the axial electronic component. have. In addition, the horizontal mold 84 has a pair of bent portions 92 with an interval slightly larger than the width of the upper mold 83.
has. Levers 93 and 94 are commonly pivotally connected to the upper end of the vertical slider 81 by a pin 95, one end of the lever 93 and the horizontal mold 84 are connected by a link 96, and one end of the lever 94 and the upper mold 8 are connected to each other by a link 96.
3 through a link 97. The other ends of these levers 93, 94 are further connected to the switching mechanism 11.
The drive force from the cam mechanism is received through the link mechanism. On the other hand, bell cranks 99, 100 are mounted on the support plate 70 by a bracket 98.
is pivotally connected by pin 101, and bell crank 99
One end of the vertical slider 81 is connected to the link 102
are connected with. As shown in FIG. 9, one end of the bell crank 100 is connected via a link 103 to a radial lead holding member 104 provided on the support block 80 so as to be slidable in an oblique direction. This radial lead holding member 104 is
This is to ensure that when the continuous cut piece 40 of the radial electronic component is to be held at 0, the lead wire is pressed against the chuck 10 to ensure that it is held. The other ends of the bell cranks 99 and 100 receive the driving force of the cam mechanism via the link mechanism of the switching mechanism 110.

As shown in FIG. 10, the switching mechanism 110 includes cams 111A to 111E, cam followers 112A to 112E that contact the cams, a switching slide bar 113, and a switching cylinder 114, and a support block 115 fixed to the main body frame. On the other hand, each of the cam followers 112A to 112E is slidably provided. In addition, the switching slide bar 11
3 is slidably provided on the support block 115 in a direction perpendicular to each of the cam followers 112A to 112E, and the switching cylinder 114 is fixed to the side surface of the support block 115. Here, the cam followers 112C and 112D are connected to the switching slide bar 1.
13, the cams 111C and 111D are always operated and connected to levers 94 and 93 via links 116C and 116D, respectively. Therefore, the bending mechanism 8
5 constantly repeats opening and closing operations. The cam follower 112A, 112B is a switching slide bar 113.
When the switching cylinder 114 is extended and moved to the forward position as shown in FIG.
13A and 113B, it becomes a released state and is operated by cams 111A and 111B. The cam follower 112A is connected to one end of a lever 117 pivotally supported on the support plate 70 via a link 116A, and the other end of the lever 117 is connected to the horizontal slider 72. Therefore, the cam follower 11
2A moves the horizontal slider 72 forward during operation to push the roller 75 on the pallet 4 side via the roller contact plate 73, and moves the component holder 22 of the pallet 4 at a position facing the chuck 10 as shown in FIG. return. Further, the cam follower 112B is connected to the bracket 98 on the support plate 70 via the link 116B.
The bell crank 99 is connected to one end of the bell crank 99, which is pivotally supported by the bell crank 99. As a result, when the cam follower 112B is operated, the vertical slider 81 is lowered via the link 116B and the bell crank 99 as shown in FIGS. enables bending action. On the other hand, during the axial operation shown in FIG. 10, the cam follower 112E is in a non-operating state with its groove 118E locked to the switching slide bar 113. This cam follower 112E is connected to the cylinder 114
When the switching slide bar 113 retreats due to the retracting movement, it passes through the groove 113E of the switching slide bar 113 and enters the released state. In this state, that is, during radial operation, the bell crank 100 connected via the link 116E is rotated,
Lower the radial lead holding member 104 and chuck the lead wire of the radial electronic component continuous cut piece 40.
Perform a pressing motion against the object. During radial operation, the switching slide bar 113 engages with the grooves 118A, 118B of the cam followers 112A, 112B to lock them. The movement of the switching slide bar 113 is based on the movement of the cam follower 112A, 11
2B, 112E grooves 118A, 118B, 118
E is aligned in a line and coincides with the switching slide bar 113, and each cam follower 112A, 1
12B and 112E are urged by an extension spring 120 in a direction to abut against the cams 111A, 111B and 111E, respectively.

Next, the operation of the above embodiment will be explained. Due to the intermittent rotational movement of the sprockets 2A to 2D, the pallet 4 for transferring electronic components executes an intermittent traveling operation. When the pallet 4 is in a position facing the supply section 5, a radial electronic component chain or an axial electronic component chain of a predetermined type is selected and cut by the supply section 5 to form a radial electronic component series cut piece 40 or an axial electronic component chain. The cut pieces 36 are supplied to the pallet 4.

If it is the radial electronic component continuous cut piece 40, the second
As shown in the figure, the pallet 4 is held on the component holding portion 22 by the holding claws 24.

If it is an axial electronic component continuous cut piece 36, it is transferred to the component receiving jig 32 as shown in FIG.
The lead wire of the axial electronic component continuous cut piece 36 is held in the engaged state in the lead engagement groove 33 . At this time, the distance between the pair of elastic arms 34 of the component receiving jig 32 is set to be slightly smaller than the dimension D between the inner edges of the tape of the axial electronic component continuous cut piece 36, and the electronic component main body 36A is The elastic arm 34 is positioned at an intermediate position.

Pallet 4 each holding continuous cut pieces of electronic components
moves in the direction of sprocket 2C where chuck 10 is located. During this normal movement, the part holding portion 22 is kept parallel to the pallet body 20 by the action of the extension spring 30 of the pallet 4.
Even when the pallet 4 reaches the sprocket 2C, the hook 4 remains in its initial position as shown in Figures 4 and 5.
6 is not engaged with the groove 60 of the slide bar 26, and the pallet 4 remains in the front position. Next, when the pallet 4 begins to travel in an arc along the sprocket 2C, the tip of the hook 46 engages with the groove 60. Thereafter, as the pallet 4 travels in an arc, the hook 46 moves backward, thereby moving the slide bar 26 and rotating the component holding section 22. When the pallet 4 facing the chuck 10 holds the radial electronic component continuous cut piece 40 as shown in FIG. Since the contact plate 73 is in the retracted position, the hook 46 engages with the groove 60 of the slide bar 26 while the pallet 4 rotates 90 degrees along the sprocket 2C.
The component holder 22 holding the continuous cut radial electronic component piece 40 is rotated to transfer the continuous cut radial electronic component piece 40 to the chuck 10 in a constant posture.
Then, the position where sprocket 2C is rotated 90 degrees,
That is, on the front side of the chuck 10, the chuck 10 clamps the lead wire of the electronic component of the radial electronic component continuous cut piece 40 held by the component holding portion 22 which projects at a right angle to the side of the pallet body. At this time, the cam follower 112B is locked and the bending mechanism 85 is in the raised position so as not to be disturbed, and the operation of the cam follower 112E causes the link 116E and the bell crank 100 to
The radial lead pressing member 104 is lowered through the
to ensure that it is held securely. After the chuck 10 has clamped the radial electronic component continuous cut piece 40, a predetermined automatic insertion operation is performed.

On the other hand, when the pallet 4 holds the axial electronic component continuous cut piece 36, when the pallet 4 comes to the position where the sprocket 2C has rotated 90 degrees, that is, in front of the chuck 10, the switching mechanism 1
10 is axial operation, cam follower 11
2A is actuated, the roller contact plate 73 in FIGS. 8 and 10 moves in the direction of arrow X through the link 116A and the lever 117 to move the roller 75, and as a result, the hook 46 is moved by the action of the extension spring 50. Regardless, the slide bar 26 returns to the forward position, and the component holder 22 is forcibly returned to the retracted position parallel to the pallet body 20 in FIG. 3. This is to prevent the component holder 22 for the radial electronic component from interfering with the movement of the bending mechanism 85 for bending the continuous cut piece 36 of the axial electronic component. At the same time, the vertical slider 81 is lowered by the action of the cam follower 112B via the link 116B and the bell crank 99, and the bending mechanism 85 is lowered to the position shown in FIGS. 8 and 11. Lower mold 82 and upper mold 83 of bending mechanism 85
And the horizontal mold 84 is waiting in an open state as shown in FIGS. 11 and 12. Next, the lever 93,
According to the rotation of 94, links 96 and 97 are lowered,
As a result, the axial electronic component continuous cut piece 36 holds its electronic component main body 36A in the main body holding groove 90 of the lower die 82.
and the upper mold 83, the horizontal mold 84
By the action of the pair of bending portions 92, the lead wire is bent diagonally upward as shown in FIGS. 13 and 14 to form a component 36B having a radial lead wire. In this state, the component 36B is removed from the component receiving jig 32 on the pallet side.
Furthermore, as shown in FIG. 15, the lead wire of the component 36B is held in a horizontal state by rotating the bending mechanism 85 in the direction of the arrow Y. Thereafter, the rotation of the bell crank 99 by the cam follower 112B is transmitted to the vertical slider 81 via the link 102, and the vertical slider 81 is lowered.As a result, the component 36B is transferred to the chuck 10 as shown in FIG. The lead wire of component 36B, which has been bent, is held in place.

As explained above, the electronic component transfer device according to the present invention includes a pallet capable of transferring radial or axial continuous electronic component fragments, and a chuck by bending the lead wires of the axial continuous electronic component fragments into a radial shape. The axial parts can be inserted using an electronic part automatic insertion device having a chuck that clamps the radial parts by combining a bending mechanism that transfers the parts to the parts and a switching mechanism that switches between the radial operation and the axial operation. is possible,
It is possible to improve the performance and effectively utilize the automatic insertion device.
