Will be separated from the chute (23) by the rotation of the rotor (30).

At the stop position where the chip separation station is rotated twice intermittently, that is, rotated by 180 degrees, the suction suction of the chip component (4) is performed by the suction nozzle (14).
This stop position is called a "chip suction station".

The next stop position of the chip suction station of the groove (29) due to the rotation of the rotor (30) is the "suction-missing chip discharge station", and the chip component mounting surface below the groove (29) of the station. (31) is open, and the chip component (4) that is not adsorbed falls and is ejected. This is because, if not ejected, there is a risk of catching on the chute (23) or the leading chip part (4) aligned with the chute (23) at the chip separation station.

The chip separation station and the next stop position of the station are rotated to the cover position by the chip pop-out prevention cover (60) rotatably provided around the support shaft (61). It is covered and prevents the chip component (4) from popping out by the rotation of the rotor (30). In the state where the cover (60) is rotated to the cover position, the chip suction station and the suction-mistake chip discharge station are not covered, and as shown in FIG. 4, all the stop positions can be rotated to a position not covered. it can.

Next, when the chip part (4) housed in the groove (29) is moved by the rotation of the rotor (30) between the chip separation station and the chip adsorption station, the chip part (4) and the rotor (30) are moved downward. ) Is vacuum-sucked to the center, but this vacuum suction will be described.

In FIGS. 1, 4 and 8 to 11,

Is provided from the chip separation station to the chip adsorption station, and a groove communication hole (64) opening below the inner side surface forming each groove (29) of the rotor (30) is provided in the vacuum groove (63). Is in communication with. further,
A vacuum groove (65) for sucking and holding the chip component (4) downward is engraved on the outside of the vacuum groove (63) of the chip component mounting surface (31). The vacuum groove (63) sucks the chip component (4) toward the center of the chip separation station at the chute (23).
This is to prevent it from hitting the outlet of the robot and biting it, and also when the chip component (4) dances or hits the cover (60) while moving along with the suction of the vacuum groove (65). This is to ensure that there is no Even if the chip component (4) is housed in each groove (29), the vacuum leaks from the vacuum grooves (63) (65) and the groove communication hole (64).

The vacuum groove (63) is through a vacuum hole (66) opened on its bottom surface, and the vacuum groove (65) is through a vacuum hole (67) opened on its bottom surface, respectively, and a vacuum passage (68) is provided.
And the vacuum passage (68A). Vacuum passage (6
A valve (6) for opening and closing the passage (68) is provided in the middle of 8).
9) is provided. The valve (69) is connected to the passage (6
8) Bushing (7
A rod (73) having two large diameter portions, an upper large diameter portion (71) and a lower large diameter portion (72), is slidably pierced through the inside of 0). (73) is urged downward in FIG. 8 by a spring (74). The lower end of the bush (70) projects inward, and the lower large diameter part (72) is locked to the projecting part to regulate the lower end position. A valve opening / closing claw (75) formed on the swing arm (46) can be engaged with the lower end surface of the rod (73), and the swing arm (46) swings counterclockwise in FIG. If the rod (73) has the claw (7
5) engages and pushes up against the spring (74). At the position shown in FIG. 8, the vacuum passage (68) closed by the upper large diameter portion (71) is communicated, and as shown in FIG. Diameter part (7
It is supposed to be closed in 2).

In this way, when the valve (69) is closed, the vacuum suction of the vacuum grooves (63) (65) is not performed, and when the valve (69) is open, the groove (2
The chip component (4) in 9) is sucked.

The vacuum passage (68) is connected to the condenser (76), and the compressed air sent from a compressed air source (not shown) supplied to the condenser (76) is exhausted (77).
By being further evacuated, a reduced pressure is generated in the vacuum passage (68), and the chip component (4) can be vacuumed.

From 0 degree of the feed lever cam (52) to 3
The movement of the swing arm (46) during one rotation of 60 degrees,
The timing of the suction operation of the tip part (4) of the rotor (30) and the suction nozzle (14) and the opening and closing timing of the valve (69) are shown in FIG. 12 from the top in this order from "swing arm""rotor""suctionoperation"" Vacuum suction "is performed.

The vacuum passage (68) also has a chute (23).
The chip parts (4) that are communicated with each other through the vacuum suction hole (78) and that are lined up in the chute (23).
3) The vacuum suction hole (7
The chip component (4) above 8) is sucked. However, since the force of blowing the compressed air from the supply hole (25) is stronger than the force of suction from the vacuum suction hole (78), there is no problem in supplying the chip component (4) to the chip separation station. Further, the vacuum suction of the vacuum suction hole (78) of the chute (23) is always performed, but since the chip component (4) is constantly suctioned, the amount of vacuum leakage is small.

The operation will be described below with the above configuration.

First, the worker manually pulls and sends the swing arm (46) of the bulk cassette feeder (8) to the rotor (30) before the automatic operation of the component mounting apparatus.
The chip parts (4) are stored in the grooves (29) of the chip separation station and the next station. In addition, the chute (2) of each cassette feeder (8)
In the inside of 3), chip parts (4) are continuously arranged from the second chamber (22) side to the outlet side.

When the automatic operation is started, the tape feeder (7) or the tape feeder (7) for supplying the component (4) to be sucked next to the suction nozzle (14) according to the mounting data (not shown) stored in the storage means (not shown). The bulk cassette feeder (8) moves along the linear guide (12) by the drive of the supply table drive motor (10) and stops at the component suction position.

At this time, it is assumed that the third bulk cassette feeder (8) from the right in FIG. 2 is stopped at the component suction position.

Further, in the cassette feeder (8), as shown in FIG. 8, the swing arm (46) is in a position where it is locked by the stopper (56), and the valve opening / closing claw (75) and the rod (73). ), A rod (73) is located at the position where it is restricted by the lower end of the bush (70), and the vacuum passage (68) has an upper large diameter portion (71). Shut off and valve (69) is closed.

Further, as shown in FIG. 5, the ratchet pawl (38) is in a position where it does not engage with the wheel groove (37).

Next, when the mounting head (15) moves to the suction station due to the rotation of the turntable (13), the cam (52) rotates through the 0 degree rotation position of FIG. The feed lever (51) moves to the left side in FIG. 3, and the swing arm (46) is moved against the tension spring (49) as shown in “Swing arm” in FIG.
In order to swing to the left from the position of the retracted end regulated by 6), first the valve opening / closing claw (75) engages with the rod (73) and is raised as shown in FIG. ) Rises so as to communicate with the vacuum passage (68) and the vacuum suction shown in FIG.
Vacuum suction is started from the vacuum grooves (63) and (65) via the (67), and the chip part (4) of the groove (29) at the stop position of the chip separation station and the rotor (30) next thereto is a groove communication hole. It is sucked toward the center of the rotor (30) via (64) and is sucked to the chip component mounting surface (31).

Further, the swinging of the swing arm (46) causes the compression spring (45) to move the rack (43) along the guide roller (44) to rotate the pinion (34). As a result, rotation of the ratchet bracket (35) causes the ratchet pawl (38) to engage the wheel groove (37) as shown in FIG. 6 to rotate the ratchet wheel (36). In this way, the rotor (30) is rotated after the vacuum suction is first performed as shown in the timing of "vacuum suction" and the rising timing of the "rotor" in FIG. When the ratchet wheel (36) is rotated 90 degrees as shown in FIG. 7, the rack (43) is stopped by the stopper (58), and the ratchet wheel (36) is stopped.
Stops rotating, and at this position, the ratchet lock pawl (40) is urged by the spring (41) to move the ratchet wheel (3).
6) Engage with the wheel groove (37). At this time, FIG.
As shown in FIG. 11, the vacuum passage (68) is kept in communication, but even if the rack (43) is stopped, the swing arm (46) continues to swing and the stopper (57) as shown in FIG. ) And stop. In this stop position, the lower large diameter portion (72) closes the vacuum passage (68) and the valve (69) is closed. Thus, when the rotor shaft (33) on which the ratchet wheel (36) is pivoted rotates by 90 degrees, the rotor (30) rotates by 90 degrees and the groove (29) at the next stop position of the chip separation station absorbs chips. Moving to the station, the component (4) in each groove (29) slides on the component mounting surface (31) and does not hit the exit of the chute (23) and the pop-out prevention cover (60). Move to the station.

Next, as shown in FIG. 12, when the swing arm (46) is at the forward end as shown in FIG. 11, the suction nozzle (14) in the state where the "suction operation" is started up is performed. A vertical movement means (not shown) descends to perform vacuum suction of the chip component (4) at the chip suction station to take it out.

Next, when the feed lever (51) returns to the left side of FIG. 3, the swing arm (46) moves to the valve (6) of FIG.
9) returns to the closed position, and the pinion (34) and ratchet pawl (38) also return to their original positions, but the ratchet wheel (36) does not rotate because it is locked by the ratchet lock pawl (40), and the rotor (30) holds the rotated position.

Next, the operation of the rotor (30) at each stop station after the rotor (30) has stopped will be described.

First, in the chip separating station, the chip component (4) is stored in the groove (29).

That is, the parts (4) aligned in the chute (23) are vacuum-sucked through the vacuum suction holes (78), the rotation of the rotor (30) starts, and the groove (29) becomes the chip separation station. The pressure for pressing the leading part (4) does not work until it further rotates, but when the rotation of the rotor (30) is stopped, the valve (26) is opened and the chute compressed air supply hole is opened. Compressed air is discharged from (25) and the chip component (4) in the chute (23) is pushed against the vacuum suction force, and the leading component (4) is pushed into the groove (29) and supplied.

On the other hand, also from the chamber compressed air supply hole (24), the compressed air is ejected at the same time from the chute compressed air supply hole (25) to remove the chip parts (4) accumulated in the second chamber (22). Blow loose, but when the valve (26) is closed, the blown loose components (4) fall and some of them enter into the chute (23). The part (4) that has entered this chute (23) is
Since the component (4) is lost between the inlet of the chute (23) and the supply hole (25) by the compressed air from 5), the chute (23) slides down by its own weight and is aligned in the chute (23). Then, the compressed air is prepared for the next rotation of the rotor (30). At this time, after the discharge of the compressed air is completed, the vacuum suction hole (78) sucks and closes the component (4) above it, and does not suck other components (4). At this time, the screws (81) (8) of the first and second adjusting mechanisms (24B) (24C)
The pushing amount of 1) is adjusted, and the adjustment mechanism (24
B) By (24C), the supply amount of compressed air is adjusted to an appropriate state in advance before the shipment of this component supply device to the market.
That is, the first adjusting mechanism (24B) adjusts the amount of compressed air supplied from the air source corresponding to each bulk cassette feeder (8) to be constant, and the second adjusting mechanism (24C) adjusts it. The cassette portion (8B) side is also adjusted so that the amount of compressed air supplied is constant. As a result, the user of this device can select which main body side (8
Regardless of which cassette unit (8B) is installed in A), an appropriate amount is always supplied without readjusting the adjusting mechanisms (24B) and (24C).

When the chute (23) is worn due to the movement of the part (4) in the chute (23), the cassette (8) is temporarily replaced with another cassette part (8A) or when the chute (23) is cleaned. When replacing the portion (8B), the first and second adjustment mechanisms (24
B) Since the amount of compressed air supplied to each part is adjusted by (24C), it is not necessary to adjust the amount of compressed air supplied at this time.

In this way, a series of operations were performed by rotating the rotor (30) by 90 degrees. Next, at the suction station, the nozzle (1) that sucked the component (4) was sucked.
The mounting head (15) having 4) stops at the recognition station due to the intermittent rotation of the turntable (13). At the station, the component recognizing device (17) recognizes the positional deviation of the component (4) attracted by the suction nozzle (14), and the nozzle rotation roller (18) causes the component to be displaced at the angle correction station which is the next stop station. (4)
The positional deviation of the rotation angle of is corrected.

Thereafter, the component (4) sucked by the suction nozzle (14) is moved to the X-axis motor (2) at the mounting station.
By the rotation of the Y-axis motor (3) and the correction of the positional deviation, the printed circuit board (5) on the XY table (1) is moved and mounted.

On the other hand, when the mounting head (15) holding the first sucked component (4) rotates, the next mounting head (15) moves to the suction station.

Then, during this intermittent rotation, the tape feeder (7) or the bulk cassette feeder (8) for supplying the next component (4) to be sucked in the same manner as described above.
Moves to the suction position of the component (4), but the valve (69) of each cassette feeder (8) remains closed.

Next, when the other cassette feeder (8) is stopped at the component suction position, the same operation as described above is performed, and the valve (69) of the cassette feeder (8) other than the component suction position is closed during this period. It is in a state of being.

As described above, the amount of vacuum leaking from the vacuum passage (68) leaks in a non-negligible amount only when the swinging arm (46) is swinging at the component suction position. Since there is almost no leakage from the suction hole (78), a large volume of the condenser (7
It is not necessary to use 6). That is, it is not necessary to use a large amount of compressed air.

Furthermore, if the valve (69) is opened and closed by using a solenoid valve or the like without interlocking with the swing arm (46), it is opened at least before the rotor (30) begins to rotate and the rotor (30) is opened. ) Is stopped, the suction nozzle (1
It may be closed before the component suction of 4), and the closed state may be continued. Alternatively, in the cassette (8) in which the component suction is not performed after the component suction, at least while the other bulk cassette feeder (8) opens the valve (69) due to the rotation of the rotor (30) or the like. The valve (69) may be closed.

[0067]

As described above, according to the present invention, the user of the component supplying apparatus does not need to adjust the air supply amount when replacing the cassette portion.
