Then, the high-speed chip component placement machine 101 is configured to take out the electronic component 108 supplied to the component supply position 112 of the selected component supply device 102 and mount it on a printed circuit board.

The supply of the electronic component 108 to the component supply position 112 in the component supply device 102 is performed as follows. That is, as shown in FIG. 15, the push rod 113 of the high-speed chip
When the feed lever 111 is pushed down, the feed lever 111 is rotated as shown in FIG. Then, as shown in FIG. 14, on the front end side of the frame 117, the link lever 115 connected to the feed lever 111 via the link 114 rotates clockwise in FIG. The shutter 116 moves backward, and opens above the component supply position 112. Then, the hand (not shown) of the high-speed chip component mounting machine 101 takes out the electronic component 108 supplied thereto from the component supply position 112 and mounts the electronic component 108 on the printed circuit board.

When the pressing operation by the push rod 113 is released, the feed lever 111 is moved to the other end 111a and the frame 11 of the component supply device 102 as shown in FIG.
As shown in FIG. 17, the tension coil spring 118 is returned to the initial position by the restoring force. With such return of the feed lever 111,
The link lever 115 is rotated in the counterclockwise direction in FIG. 13, and the shutter 116 linked therewith moves forward to close the part supply position 112 above.

In the component supply device 102, a tape ratchet 119 is provided at the front end side of the frame 117 so as to be rotatable via a fulcrum shaft 120 coaxially with the link lever 115. When the feed lever 111 is pressed down at a high speed, the link lever 115 connected to the feed lever 111 via the link 114 rapidly rotates clockwise in FIG. At this time, the link lever 11
The ratchet pawl 121 rotatably attached to the gear 5 and meshing with the tape ratchet 119 moves clockwise around the fulcrum shaft 120. The ratchet claw 121 is rotationally biased by a biasing means in a direction in which it engages with the tape ratchet 119 (counterclockwise direction in FIG. 14).

The tape ratchet 119 is provided with a positioning and holding mechanism (not shown) that rotates only in the counterclockwise direction in FIG. 14 and does not rotate in the clockwise direction. Therefore, the tape ratchet 119 is connected to the feed lever 111.
When the ratchet claw 121 is moved by being pushed down, it does not rotate clockwise in FIG. Therefore, at this time, the ratchet claw 121 is
After getting over 19a, go to the next ratchet tooth 119b. When the link lever 115 has finished rotating in the clockwise direction in FIG. 14, the ratchet pawl 11 is rotated and urged in the counterclockwise direction in FIG. 14 by the urging means. The teeth 119b do not exceed the ratchet teeth 119b.

Next, when the pressing operation of the feed lever 111 by the push rod 113 is released, as shown in FIG. 13, the link lever 115 rotates counterclockwise in the drawing. At this time, the ratchet pawl 121 slides and meshes between the valleys between the ratchet teeth 119a and the ratchet teeth 119b while being pressed against the tooth surface of the ratchet teeth 119b of the tape ratchet 119, and moves the tape ratchet 119 counterclockwise in FIG. Rotate. The tape ratchet 119 has feed holes 110 for the component storage tape 104,
110 are integrally provided with a tape feeding claw engaged with the tape. Therefore, the tape ratchet 1
When the electronic component 108 is rotated, the component storage tape 104 is fed forward by a predetermined amount, and the electronic component 108 is removed from the concave portion 10.
The recess 1 that houses the electronic component 108 located next to 7
07 is located at the component supply position 112.

On the other hand, as shown in FIG. 12, the cover tape 109 of the component storage tape 104 is
The sheet is peeled off from the backing tape 106 at a position closer to the front side, that is, at a slit 122 located on the reel mounting portion side, and is pulled out from the slit 122 upward. Then, the cover tape 109 is taken up by a take-up reel 123 supported rotatably coaxially with the feed lever 111. As shown in FIG. 15, the rotating shaft of the take-up reel 123 has
The one-way clutch 124 is provided therein, and the take-up reel 123 is rotatable only in the counterclockwise direction in FIG.

Further, as shown in FIG. 15, there is provided a swing lever 125 whose base end is rotatably supported coaxially with the feed lever 111. This swing lever 125
And the other end 111a of the feed lever 111 are connected by a tension coil spring 126. In addition, the swing lever 125 includes the feed lever 11.
A pressed portion 125a protruding toward one is provided.

The take-up reel 123 is integrally provided with a take-up reel ratchet 127, as shown in FIG. Further, the winding claw 1 is provided on the tip side of the swing lever 125.
28 is rotatably supported. This winding claw 128
The take-up reel ratchet 127
To be pressed in the direction of pressing against.

As described above, when the feed lever 111 is pushed down by the push rod 113, the swing lever 1
25 is pressed against the pressed portion 125a by the feed lever 111 which rotates clockwise in FIG.
It is rotated clockwise. At this time, swing lever 1
The take-up claw 128 supported on the tip side of the take-up reel 25 slides on the peripheral edge of the take-up reel ratchet 127, and engages the claw 128a with the ratchet 127 when the rotation of the swing lever 125 stops. .

When the pressing operation of the push rod 113 on the feed lever 111 is released and the feed lever 111 returns to the initial position by the restoring force of the tension coil spring 118 as shown in FIG.
25 is rotated counterclockwise in FIG. 17 by being pulled on the distal end side via a tension coil spring 116. Then, as shown in FIG. 18, the winding claw 18 supported on the distal end side of the swing lever 125 pulls the ratchet 127 to rotate in a counterclockwise direction in FIG. 18 with a force corresponding to the force of the coil spring 116. Let it. By the rotation of the ratchet 127, the take-up reel 123 is rotated in the counterclockwise direction in FIG. 18 to take up the cover tape 109 by a predetermined amount.

[0016]

In the above-described component supply apparatus, the high-speed chip component mounting apparatus 1
As the tact time for mounting the chip-type electronic component 108 of FIG. 1 is accelerated, the chip-containing electronic component 108 can be supplied to the fixed position of the component supply position 112 with high precision by sending the component storage tape 104 at a constant pitch. There is a problem of disappearing.

Further, as the speed increases, the vibration increases immediately after the electronic component 108 is sent to the component supply position 112, that is, immediately before the electronic component 108 is taken out.
The posture of the electronic component 108 becomes unstable,
8 cannot be taken out.

For example, when the feed lever 111 is returned at high speed by the restoring force of the tension coil spring 118, the swing lever 125 is pulled by the force of the tension coil spring 126, but the position is maintained by the potential energy of its own weight. And the operation timing is delayed. Further, the swinging lever 125 once rotated tries to rotate the take-up reel 123 through the take-up claw 128 to a position corresponding to the amount of force of the tension coil spring 126. In addition, the kinetic energy of the swing lever 125 and the like when it is turned increases due to the mass of the swing lever 125 and the like.

Further, if the amount of force of the tension coil spring 126 is increased in order to reduce the delay in the operation timing of winding the cover tape 109, the moment of inertia of the swing lever 125 increases, and the winding reel 123
Too much, and as a result, the cover tape 109
Too much. Then, the mounting tape 106 is deformed, or a force that is excessively applied acts, so that the accuracy of the constant pitch feeding is disturbed, and the chip-type electronic component 108 cannot be accurately supplied to a fixed position of the component supply device 101. .

Further, when the swing lever 125 is flipped up in the counterclockwise direction in FIG. 16 by the feed lever 111, impact vibration generated when the feed lever 111 hits the pressed portion 125a of the swing lever 125 is generated. There is a problem in that the posture of the electronic component 108 immediately before being sucked is disturbed, and mounting stability is impaired.

Further, the life of the tension coil spring 126 is remarkably reduced due to the ramping or surging (resonance) of the tension coil spring 126 generated when the swing lever 125 is flipped up at a high speed and returned after a predetermined time has elapsed. Or the take-up claw 128 is the take-up reel ratchet 127
There are also problems of vibration and wear when sliding.

In the mechanism for feeding the component storage tape 104 of the component supply device 102 at a high speed at a constant pitch, when the feed lever 111 is pressed down at a high speed, the link lever 115 connected via the link 114 is rapidly moved. 14 is rotated clockwise in FIG. A ratchet pawl 121 is mounted on the link lever 115, and when the link lever 115 rotates clockwise in FIG.
Over the 19 ratchet teeth 119a, it heads to the next ratchet tooth 119b. At this time, the ratchet claw 121
14 is urged to rotate in the counterclockwise direction in FIG. 14, and thus vigorously collides against the tape ratchet teeth 119b. The vibration at this time increases as the speed increases,
The problem is getting bigger.

Accordingly, the present invention has been proposed in view of the above-mentioned circumstances, and is intended to reduce the delay in the start operation timing of the cover tape winding and to prevent the winding reel from rotating more than necessary. To prevent the cover tape from being unnecessarily wound up, to prevent impact vibration when the swing lever is flipped up, to prevent the tension coil spring from running out and surging, and to prevent the take-up claw and take-up reel ratchet from slipping. It is an object of the present invention to provide a component supply device capable of smoothly supplying components by eliminating vibration and wear of the components.

[0024]

In order to solve the above-mentioned problems, a component supply device according to the present invention comprises a mount tape having recesses containing electronic components formed at a constant pitch and a tape attached to the mount tape. A component storage tape comprising a cover tape for closing the concave portion, and a component supply for supplying the electronic components in the winding concave portion to a component supply position by peeling off the cover tape while feeding the component storage tape at a constant pitch; A device, wherein a take-up reel for winding a cover tape and one of electronic components stored in a component storage tape are moved to a component supply position by being rotatably supported and rotated in one direction. A feed lever for rotating the feed lever in another direction, a biasing means for biasing the feed lever in another direction, and a feed lever rotated in one direction by a rotation operation in one direction.

A one-way clutch that enables rotation only in the take-off direction is provided, and the take-up reel and the feed lever are connected via a wave washer whose connection force in the rotation direction is adjustable. Is what you do.

That is, in the component supply device according to the present invention, the swinging lever used in the conventional component supply device is not required, and a winding claw to be attached to the tip end thereof, and a winding reel ratchet meshing with the winding claw are provided. Further, a tension coil spring for urging them is unnecessary.

As shown in FIG. 1, a reel 105 around which a component supply tape 104 is wound is rotatably attached to the component supply device. Further, a feed lever 2 is provided in the component supply device. Each time the feed lever 2 is pressed down, the electronic components 108 stored in the component storage tape 104 are supplied one by one to a predetermined component supply position 6 of the component supply device.

The feed lever 2 is, as shown in FIG.
It has a "U" shape when viewed from the side, and its bent portion is rotatably supported on the frame 1 via the support shaft 10. One end of the feed lever 2 is a portion pressed by the push bar 113 of the high-speed chip component mounting machine 101. A tension coil spring 8 serving as an urging means is stretched between the other end 2a of the feed lever 2 and the frame 1.

In the high-speed chip component mounting machine 101,
The moving base 103 is moved in the direction of the arrow A in FIG. 11, and the component supply device to which the component storage tape 104 storing the necessary chip-type electronic components 108 is attached is selected. The selected component supply device is stopped at a predetermined component suction position. Then, the high-speed chip component mounting machine 101
Is configured to take out the electronic component 108 supplied to the component supply position 6 of the selected component supply device and mount it on a printed circuit board.

The supply of the electronic component 108 to the component supply position 6 in the component supply device is performed as follows.
That is, as shown in FIGS. 2 and 3, when the push rod 113 of the high-speed chip component mounting machine 101 located above the feed lever 2 of the component supply device pushes down the feed lever 2 of the component supply device, FIG. As shown, the feed lever 2 is rotated. Then, as shown in FIG.
At the front end side of the frame 1, the link lever 4 connected to the feed lever 2 via the link 3 rotates clockwise in FIG. 8, and the shutter 5 connected to the link lever 4 moves backward. Then, the upper part of the component supply position 6 is opened. Then, the hand (not shown) of the high-speed chip component mounting machine 101 takes out the electronic component 108 supplied thereto from the component supply position 6 and mounts the electronic component 108 on the printed circuit board.

When the pressing operation by the push rod 113 is released, the feed lever 2 is pulled, as shown in FIG. 6, by the tension coil spring 8 stretched between the other end 2a and the frame 1 of the component supply device. Due to the restoring force, as shown in FIG. 6, it is returned to the initial position. With the return of the feed lever 2, the link lever 3 is rotated in the counterclockwise direction in FIG. 7, and the shutter 5 interlocked with the link lever 3 moves forward, and moves above the component supply position 6. Close.

Further, a tape ratchet 9 is provided coaxially with the link lever 4 on the front end side of the frame 1.
Are rotatably provided via a fulcrum shaft 10. When the feed lever 2 is pressed down at a high speed, the link lever 4 connected to the feed lever 2 via the link 3
It rotates rapidly in the clockwise direction in FIG. At this time, the tape ratchet 9 is attached rotatably to the link lever 4.
The ratchet pawl 11 meshing with the shaft 10 moves clockwise around the fulcrum shaft 10. The ratchet pawl 11 is rotationally biased by a biasing means in a direction meshing with the tape ratchet 9 (counterclockwise direction in FIG. 8).

The tape ratchet 9 is provided with a positioning and holding mechanism (not shown) which rotates only in the counterclockwise direction in FIG. 8 and does not rotate in the clockwise direction. Therefore, the tape ratchet 9 does not rotate clockwise in FIG. 8 even when the feed lever 2 is pressed down and the ratchet pawl 11 moves. Therefore, at this time, the ratchet pawl 11 goes over the ratchet tooth 9a and moves to the next ratchet tooth 9b. Here, the ratchet claw 11
Since the rotation is urged in the counterclockwise direction in FIG. 8, when the ratchet tooth 9a is passed, the next ratchet tooth 9
It rotates vigorously in the direction corresponding to b. Ratchet claw 11
A variably adjustable stopper member 21 is attached to a position where the ratchet pawl 11 comes into contact with immediately before the ratchet teeth 9b come into contact with the next ratchet tooth 9b. The stopper member 21 is formed from a shock absorbing material. This stopper member 21
Accordingly, the link lever 4 ends the clockwise rotation in a state where the ratchet teeth and the ratchet claw 11 do not directly collide with each other. The fact that the ratchet teeth and the ratchet pawls 11 do not directly collide with each other means that the ratchet teeth and the ratchet pawls 11 are made of a material having high hardness in order to improve durability and wear resistance. The effect of suppressing the occurrence of is large.

Next, when the pressing operation of the feed lever 2 by the push rod 113 is released, as shown in FIG. 7, the link lever 4 rotates counterclockwise in the figure. At this time, the ratchet claw 11 is pressed against the tooth surface of the ratchet tooth 9b of the tape ratchet 9 while the ratchet tooth 9a is pressed.
The tape ratchet 9 is rotated in a counterclockwise direction in FIG. 7 by sliding down and meshing between the valleys of the tape ratchet 9 and the ratchet teeth 9b. The tape ratchet 9 is integrally provided with a tape feed claw that is engaged with the feed holes 110, 110... 110 of the component storage tape 104. Therefore, when the tape ratchet 9 rotates, the component storage tape 104 is moved forward by a predetermined amount, and the concave portion 107 storing the electronic component 108 located next to the concave portion 107 from which the electronic component 108 is taken out is supplied. It is located at position 6.

On the other hand, as shown in FIG. 7, the cover tape 109 of the component housing tape 104 is provided with
The tape is peeled off from the backing tape 106 at the position 2 and the slit 12
Pulled upward from. And this cover tape 1
Reference numeral 09 denotes a take-up reel 13 rotatably supported via a support shaft 10 coaxially with the feed lever 2 as shown in FIG.
It is wound up. The rotation axis of the take-up reel 13 is shown in FIG.
As shown in FIG. 7, a one-way clutch 14 is provided, and the take-up reel 13 is rotatable only in a direction in which the cover tape 109 is taken up (counterclockwise in FIG. 6).

The take-up reel 13 and the feed lever 2
As shown in FIG. 4, the wave washer 20
Is decorated. Therefore, a certain connection force is generated between the field lever 2 and the take-up reel 13 due to the contact reaction with the wave washer 20.

In this component supply device, the feed lever 2 is connected to the push rod 113 of the high-speed chip component mounting machine 101.
When one end of the feed lever 2 is pushed down, the feed lever 2 is turned clockwise in FIG. 5 against the urging force of the tension coil spring 8 as shown in FIG.

When the feed lever 2 is turned by the push rod 113 against the urging force of the tension coil spring 8,
As shown in FIG. 8, the shutter 5 is moved rearward via the link 3 and the link lever 4, and opens above the component supply position 6. Thus, the electronic component 108 located at the component supply position 6 is taken out by the high-speed chip component mounting machine 101.

In this component supply apparatus, as described above, the electronic component 108 by the high-speed chip component mounting machine 101 is used.
Immediately before the suction, the stopper member 21 is provided, so that the occurrence of vibration is suppressed, and the component suction posture and the suction quality can be stabilized.

The rotation of the feed lever 2 in the clockwise direction in FIG. 5 causes the take-up reel 13 to rotate in the same direction as the feed lever 2 by the action of the wave washer 20. Since the feed lever 2 cannot be rotated in the same direction by the action of the clutch 14, slippage with respect to the wave washer 20 occurs,
Keep it as it is.

When the pressing operation by the push rod 113 is released, the feed lever 2 is rotated counterclockwise in FIG. 5 by the restoring force of the tension coil spring 8, and as shown in FIG. Is returned to the position. With the return of the feed lever 2, as shown in FIG. 7, the link lever 4 is rotated counterclockwise in FIG. 7 and moves the shutter 5 connected to the link lever 4 forward. Then, the upper part of the component supply position 6 is closed.

At this time, the take-up reel 13 is synchronously rotated in the counterclockwise direction in FIG. 6 following the feed lever 2 by the coupling force due to the contact resistance of the wave washer 20, and the cover tape 109 is moved by a predetermined amount. Take up. At this time, the take-up reel 13 is rotated by a force corresponding to a constant rotational force (torque) due to the contact resistance force of the wave washer 20 to take up a predetermined amount of the cover tape 109. Causing slippage. Due to such slippage of the wave washer 20, a torque limiter function in which a winding force is not applied beyond a certain rotation torque is realized.

Further, the coupling force due to the contact resistance of the wave washer 20 has a high effect on the initial rotational force when the feed lever 2 starts to rotate counterclockwise in FIG. This is because the starting static torque is much greater than the dynamic torque. That is, since the starting torque at the start of winding of the winding reel 13 is increased, the high-speed followability (winding startability) is improved.

In the wave washer 20,
A desired torque control is possible by adjusting the leaf spring force based on the wave amount and the gap for housing the wave washer 20 in consideration of the required torque at the start of winding. Thus, it is possible to realize a torque limiter function that prevents the cover tape 109 from being unnecessarily wound while enabling high-speed winding start.

It should be noted that the shapes and structures of the respective parts shown in the above-described embodiments are merely examples of the specific embodiments to be carried out when carrying out the present invention, and the technical scope of the present invention is thereby described. Should not be interpreted restrictively.

[0048]

As described above, in the component supply device according to the present invention, the feed lever for moving the electronic component stored in the component storage tape to the component supply position, and the feed lever is rotated by the return of the feed lever. A take-up reel 13 for winding a cover tape of the component storage tape,
A one-way clutch for preventing reverse rotation of the take-up reel is provided on a fulcrum shaft of the take-up reel, and the take-up reel and the feed lever are connected via a wave washer whose connection force in the rotational direction is adjustable.

The coupling force between the take-up reel and the feed lever is an initial rotational force at the start of rotation, that is, the static torque at the start is much larger than the dynamic torque. The starting torque is high and the high-speed followability is good. Further, by adjusting the leaf spring force based on the wave amount and the gap for housing the wave washer in consideration of the required torque at the time of starting the wave washer, desired torque control is possible. That is,
It is possible to function as a torque limiter, and thereby, it is possible to prevent the cover tape from being unnecessarily wound up while enabling high-speed starting.

Further, since the number of components of this component supply device is smaller than that of the conventional component supply device, it is possible to simplify the production and reduce the cost.

In the component supply device according to the present invention, since the mass is reduced by reducing the number of components and the moment of inertia of the winding system is suppressed, the startability at the start of winding of the winding reel is further improved. It is possible to enhance the high-speed follow-up property by suppressing the overrun (over-rotation) and to prevent the cover tape from being unnecessarily wound up.

Further, this component supply device does not have a mechanism for sliding the take-up claw on a take-up reel ratchet (ratchet wheel) engraved around the take-up reel.
Vibration can be suppressed, and components can be supplied stably without causing the supplied components of the component supply device to vibrate.

Also, since this part supply device eliminates direct contact between the ratchet teeth and the ratchet pawl,
Occurrence of vibration immediately before the suction is suppressed, and the component supply attitude can be stabilized without increasing the vibration of the supplied component, and the component supply quality can be improved. This effect is particularly remarkable when components such as ratchet teeth and ratchet claws are formed of a material having higher hardness in order to improve durability by increasing the speed.

As described above, in the component supply apparatus according to the present invention, adverse effects and resonance due to vibration of the components are prevented, fatigue wear is prevented, and the life of the apparatus is extended.

That is, the present invention reduces the delay of the start operation timing of the cover tape winding and prevents the winding reel from rotating more than necessary so that the cover tape is not unnecessarily wound. In addition, it eliminates the impact vibration when the swing lever is flipped up, the runaway and surging of the tension coil spring, and eliminates the vibration and wear when the take-up claw and the take-up reel ratchet slide. Thus, it is possible to provide a component supply device configured as described above.
