The second feed lever 62 is connected to the first feed lever 37 via a connecting link 67. That is, one end of the connecting link 65 is connected to the second feed lever 62 via the pin 66, and the other end is connected to the first feed lever 3 via the pin 67.
It is designed to be connected to 7.

The pin 61 rotatably supports the feed gear 71. A large number of pins 72 are planted on the outer peripheral surface of the feed gear 71, and the component holding tape is fed by these pins 72. Moreover, a ratchet gear 73 is attached to the side surface side of the feed gear 71, and the ratchet gear 73 is provided with a second ratchet gear 73 as shown in FIG.
Ratchet pawl 74 supported by the feed lever 62
Is engaged with. Moreover, the returning position of the ratchet pawl 74 is restricted by the eccentric pin 75.
Therefore, by adjusting the rotational position of the pin 75, the stop position of the ratchet pawl 74 is adjusted.

Further, a stop lever 76 is arranged below the shutter 55 to regulate the returning position of the ratchet gear 73. Stop lever 7
6 is rotatably supported by an eccentric pin 77, and by adjusting the rotation of the eccentric pin 77, the stop position of the ratchet gear 73 by the stop lever 76 is adjusted. Further, the stop lever 76 is urged to rotate counterclockwise about the pin 77 by the spring 78 in FIG. 5, so that the tip end portion of the stop lever 76 is correctly positioned.
To be engaged with.

As shown in FIGS. 9 to 11, a lock lever 82 is arranged on the side of the tip of the base 20 opposite to the side on which the ratchet gear 73 is attached, and a pin 83 is provided. It is rotatably supported by. Moreover, by the spring (not shown) wound around the pin 83,
The lock lever 82 is urged to rotate in the counterclockwise direction in FIG. 9 about the pin 83. Further, a stopper pin 84 is planted on the base 20 so as to be located on the side surface side of the lock lever 82.

Further, a lock release lever 85 is arranged below the lock lever 82, and is rotatably supported by a pin 86. The protrusion 87 formed on the side portion of the lever 85 presses the side portion of the lock lever 82, whereby the lock releasing operation is performed. Also, this lock release lever 85
Is connected to the second feed lever 62 via a connecting pin 88 that is planted on the lower end side thereof.

Below the base 20 is shown in FIGS.
Two pins 92 and 98 are planted as shown in FIG.
The pin located on the tip side of the base 20 is composed of a circular reference pin 98, whereas the pin implanted on the rear side is composed of an eccentric pin 92. The pin 92 is fitted in a pin hole 93 of the base 20 and fixed to the base 20 by a nut 94 and a washer 95, as shown in particular in an enlarged scale in FIG.

In order to receive the pin 20, a long hole 96 as shown in FIG. 7 is formed on the mount table for mounting the component supply unit 11. This long hole 9
The width of 6 is the same as the diameter of the eccentric pin 92. Therefore, by rotating the pin 92, the base 20 can be adjusted laterally at the eccentric pin 92, that is, in the direction shown by the arrow 97, as shown in FIG.

Next, the structure of the take-up reel 36 for winding the above-mentioned top tape will be described with reference to FIGS. The take-up reel 36 is used in combination with the drive wheel 103, as shown in FIG. The drive wheel 103 is a wheel that is rotatably supported by a pin 35 of a mounting piece 34 and is intermittently fed by a ratchet pawl 38, and a boss 104 is projectingly provided on the center side thereof as shown in FIGS. 13 and 14. ing. Moreover, three push-up claws 105 are continuously provided on the outer peripheral side of the boss 104.

On the other hand, the top tape take-up reel 3
As shown in FIGS. 15 and 16, 6 has a winding portion 109 formed on the center side thereof, and the winding portion 109
A slit 111 is formed on the flange 110 at a part of the outer peripheral side in the circumferential direction, and the slit 111 configures the winding portion 109 to be partially deformable in the radial direction.

When such a take-up reel 36 is combined with the drive wheel 103, the push-up claws 105 of the drive wheel 103 form the outer periphery of the portion where the slit 111 of the take-up portion 109 of the take-up reel 36 is formed. It will be pushed up to the side as shown in Figure 12,
In that state, the two will be combined.

Therefore, after the top tape is wound by the winding portion 109 of such a top tape winding reel 36, the winding reel 36 is driven by the drive wheel 10.
When the tape is removed from No. 3, the winding portion 109 in which the slit 111 is formed is deformed toward the center side in the radial direction due to the winding force of the top tape, whereby the top tape can be easily removed.

17 to 22 show a modified top tape take-up reel 36. The drive wheel 103 in combination with the modified reel 36 is shown in FIGS.
As shown in 0, the boss 104 is formed on the center side, and three engagement holes 115 are formed on the outer peripheral portion of the boss 104 at intervals of 120 degrees in the circumferential direction.

On the other hand, the take-up reel 36 is shown in FIGS.
As shown in FIG. 2, the winding portion 109 on the center side is divided into a plurality of pieces in the circumferential direction by the slits, and the three divided portions form engaging claws 116. Notches 117 are formed at the ends of these engaging claws 116.

Such reel 36 is used for the wheel 10 described above.
When combined with 3, as shown in FIGS. 17 and 18,
The engaging claw 116 is inserted into the engaging hole 115 of the flange 110. In this state, when the top tape take-up reel 36 is rotated with respect to the drive wheel 103 in the circumferential direction by a predetermined angle, the notch 117 of the engaging claw 116 is formed in the engaging hole 115 formed in the flange of the drive wheel 103. To engage the edges,
As a result, the top tape take-up reel 36 is assembled.

According to the take-up reel 36 of such a modified example, as shown in FIGS. 17 and 18, the top tape is wound in a state of being coupled with the drive wheel 103, and a predetermined amount of the top tape is wound. Once taken, the top tape take-up reel 36 is separated from the drive wheel 103. Then, the winding portion 109, which is divided into a plurality of pieces by the slit of the winding reel 36, is deformed toward the center in the radial direction, whereby the top tape is easily removed from the reel 36.

Next, the operation of the component supply unit 11 of the electronic component supply apparatus having the above structure will be described. As shown in FIG. 1, the component supplied by the component supply unit 11 is sucked by the mount head 15 and then mounted on a predetermined position on the printed board 14 positioned by the XY table 13. It has become so. The selection of the plurality of component supply units 11 is performed by moving the X-direction moving table 12 on which the component supply units 11 are mounted. Therefore, here, it is necessary to arrange at least the number of component supply units 11 corresponding to the types of components on the X-direction moving table 12.

The operation of each component supply unit 11 will be described. As shown in FIG. 3, the first actuator 12
1 pushes the tip of the first feed lever 37 downward, or the second actuator 122 pushes the second feed lever 37 downward.
The feed lever 62 is pushed to the right. Although two actuators 121 and 122 are shown here for the sake of convenience, only one type of actuator is actually required.
Further, instead of the actuator, a pressing piece may be provided on the mount head 15, and the one of the feed levers 37 and 62 may be pressed by this pressing piece.

When the first actuator 121 presses the feed lever 37, this causes the ratchet pawl 38 to move.
The top tape take-up reel 36 is intermittently driven via the to wind the top tape, and the rotational movement of the feed lever 37 is transferred to the second feed lever 62 shown in FIGS. 4 and 5 via the connecting link 65. As a result, the second feed lever 62 is rotated about the pin 61 in the clockwise direction in FIG. Then, the ratchet pawl 74 sends the ratchet gear 73 in conjunction with the backward movement of the second feed lever 62, and the stop lever 76 prevents the ratchet gear 73 from rotating in the reverse direction.
Then, the component holding tape wound on the component holding tape supply reel 23 is moved to the base 20 by the pin 72 of the feed gear 71 having the ratchet gear 73 attached to the side surface.
The sheet is intermittently fed along the guide surface 32.

When the second feed lever 62 is rotated clockwise about the pin 61, the pin 63 of the lever 62 moves the shutter 55 to the right in FIG. 5, and the component take-out hole 57 (see FIG. 2). ) Will be exposed. Therefore, the component held by the component holding tape is exposed through the component take-out hole 57. Therefore, at the portion of the chuck on the tip side of the mount head 15 shown in FIG. 1, the shutter 55 is opened and the component exposed by the component extraction hole 57 is chucked and taken out.

When the actuator 121 is subsequently moved back, the feed lever 37 is moved back, whereby the second feed lever 62 is moved back about the pin 61 in the counterclockwise direction in FIG. Becomes,
The ratchet pawl 74 intermittently feeds the ratchet gear 73 as described above. In addition, the feed lever 62
When the pin 63 rotates in the counterclockwise direction, the pin 63 is released from the shutter 5.
5 is moved to the front end side, and the component extraction hole 57 of the cover 52 is moved.
Will come to close.

When the second actuator 122 is used instead of the first actuator 121, the second feed lever 62 is directly rotated by the actuator 122, and the second feed lever 62 is rotated. The subsequent movement associated with the rotation of is similar to that of the first feed lever.

When the second feed lever 62 is rotated by the actuator 122, the rotational movement of the second feed lever 62 is performed via the link 65.
7, the feed lever 37 allows the top tape take-up reel 36 to be intermittently fed via the ratchet pawl 38. Therefore, even when the second actuator 122 is used, the final movement is the same.

The component supply unit 11 according to the present embodiment as described above is provided with the first feed lever 37 and the second feed lever 62 as shown in FIG. By pushing the feed levers 37 and 62 of
The parts are taken out when intermittently fed.
Therefore, it can be applied to both a high speed type electronic component mounting machine and a low speed type electronic component mounting machine. Alternatively, the component supply unit 11 can be applied to the odd-shaped electronic component mounting machine. Therefore, this component supply unit can be applied to various mount machines by replacing the component holding tape supply reel 23, and a component supply unit with high versatility can be provided.

As shown in FIGS. 3 and 4, two pins 9 are provided on the lower surface of the base 20 of the component supply unit 11.
2, 98 are planted, and the rear pin 92 is composed of an eccentric pin. That is, as shown in FIG. 6, the pin 92 is eccentric by e with respect to the center, and such an eccentric pin 92 is received in the long hole 96 whose width is equal to the diameter of the pin 92 as shown in FIG. Therefore, by rotating the pin 92, the base 20 can be swung in the direction indicated by the arrow 97 about the pin 98 as shown in FIG.

Therefore, the tip side of the base 20, that is, FIG.
In, the tip end side portion of the base 20 on the side opposite to the eccentric pin 92 with respect to the reference pin 98 and from which the chip-shaped component is taken out by the mount head 15 can be adjusted in the direction indicated by the arrow 99. Therefore, the tape feeding direction supplied by the component holding tape, that is, the base 20
The take-out position of the component can be adjusted in the direction perpendicular to the length direction of the, and the take-out position can be surely adjusted.

This makes it possible to increase the adsorption rate of the entire mount machine that mounts components. That is, according to the conventional chip component supply device, since the position adjustment of the component supply unit 11 can be performed only in the feeding direction of the base 20, the chip component suction accuracy is low, but by providing the eccentric pin 92. By solving such a problem, the suction accuracy can be improved.

A cover 52 is attached to the tip of the base 20 as shown in FIGS. 9 to 11, and is rotatable by a pin 53. That is, when the component holding tape is inserted, or when a trouble occurs, the cover 52 can be opened together with the auxiliary cover 46 as shown in FIG. 10 if necessary, and the chip-shaped electronic components are evenly spaced. When the enclosed component holding tape is delivered to the component take-out position through the transport section, the covers 46 and 52 are closed to prevent the component holding tape from rising, as shown in FIG. Moreover, as shown in FIG. 10, the cover 52 is locked by the lock lever 82 in the opened state, which facilitates handling of the tape when the cover 52 is opened.

Moreover, when the second feed lever 62 is rotated as shown in FIG. 11 to supply the components, the lock release lever 85 is centered on the pin 86 via the connecting pin 88 as shown in FIG. It is designed to be rotated counterclockwise. The protrusion 87 of the release lever 85 presses the side portion of the lock lever 82 to perform the lock release operation in conjunction with such a rotational movement. In this way, the cover 52 is automatically closed in association with the supply of parts.

Therefore, when the first feed lever 37 or the second feed lever 62 is pushed after the component holding tape is set to the component take-out position, the lock release lever 85 which is interlocked with the second feed lever 62 via the connecting pin 88 is used. The lock lever 82 releases the lock, the cover 52 presses the tape, and thereby prevents the tape from floating, which makes setting easier and faster than before. Further, since the lock is released by rotating the feed lever 62, even if the cover 52 is left open and forgotten to be closed, the setting error can be prevented.

On the chip-shaped electronic parts supplied with the tape through the parts holding tape supply reel 23,
Although a top tape is applied, this top tape is peeled off at the shutter 55 as shown in FIGS. 2 and 3, and is taken up by the top tape take-up reel 36.

As shown in FIGS. 15 and 16, the take-up reel 36 for winding the top tape has slits 11
A part of the take-up portion 109 can be deformed in the radial direction by 1, and when combined with the boss 104 of the drive wheel 103, the push-up claw 105 pushes it up to the outer peripheral side in the radial direction as shown in FIG. It is designed to be combined with each other.

Therefore, when the take-up reel 36 is removed from the drive wheel 103 after winding a predetermined amount of the top tape, the take-up portion 109 is removed from the slit 111 of the take-up portion 109 by the winding-up force of the top tape. The top tape can be easily removed from the winding portion 109 by being deformed toward the center in the radial direction. That is, unlike the prior art, it is not necessary to pull the top tape by hand to remove it, and thus it does not take time to remove the top tape from the take-up reel.

According to the modified take-up reel 36 shown in FIGS. 17 to 22, the reel 36 is mounted on the drive wheel 1.
When it is combined with No. 03, the winding portion 109 is fixed in the radial direction with the engagement claw 116 engaged with the engagement hole 115. Moreover, since the winding portion 109 is divided into a plurality of pieces in the circumferential direction by the plurality of slits, the tape wound around the winding portion 109 is such that the winding reel 36 can be removed from the drive wheel 103. By the winding force of the top tape, the winding portion 109
Is deformed to the center side in the radial direction, so that it can be easily removed from the reel 36.

That is, according to the modified example, the take-up reel 3
6 is combined with the drive wheel 103 to make the winding portion 109 into a substantially circular shape, and by removing from the drive wheel 103, the winding portion divided by the slit including the engaging claw 116 of the winding portion 109. The fact that one end of 109 is deformed toward the center in the radial direction is used to facilitate the removal of the top tape from the reel 36. Therefore, also in this case, the top tape can be easily removed from the take-up reel 36.

Therefore, by such rotation adjustment of the eccentric pin, the base is pivoted about the reference pin, and the take-out position of the electronic component provided on the tip end side of the base is located in the lateral direction of the base. Will be adjusted. Therefore, it becomes possible to adjust the pick-up position of the electronic component to an optimum position, whereby the adsorption rate of the electronic component by the mount head can be improved and the variation of the adsorption rate can be eliminated.
