Next, the control system of the component mounting apparatus constructed according to this embodiment will be explained based on FIG.

(85) is a CPU, and RAM (86)
It controls various operations related to the operation of mounting the chip component (4) on the printed circuit board (5) according to the program stored in the ROM (87) based on various data stored in the ROM (87).

A component extraction memory (88) is provided in the RAM (86) for each bulk cassette feeder (8), and a component extraction memory (88) is provided for each bulk cassette feeder (8).
34) It remembers whether the part (4) is taken out from (35). When "0" is stored, the part (4) is taken out from both rotors (34) and (35), when "1" is stored, the part (4) is taken out from the rotor (34), and when "2" is stored, the part (4) is taken out from the rotor (34) and (35). 35). (89) is an interface, and a drive circuit (90)
through the feed table drive motor (10) and plunger (7
0) etc. are connected to the CPU (85).

The operation of the above configuration will be explained below.

First, before automatic operation of the component mounting device, the operator manually pulls and feeds the swing arm (60) of the bulk cassette feeder (8), and then moves the swing arm (60) of the bulk cassette feeder (8)
The chip components (4) are stored in the chip separation station (35) and the groove (33) at the stop position rotated 90 degrees from the station. In addition, chip components (4) are continuously arranged in the first chute (25) and second chute (26) of the cassette feeder (8) from the second chamber (23) and (24) side to the exit side, respectively. ing. The memory (88) in the RAM (86) contains the rotor (3
4) "0" is stored in accordance with the state of (35). The initial setting of this memory (88) can be performed by an operator using an operation unit (not shown) in accordance with the states of the rotors (34) and (35). Alternatively, "0" may be stored at the start of operation.

[0038] When automatic operation starts, the RAM (86)
According to the installation data (not shown) stored in the CPU
(85) controls the drive of the supply table drive motor (10), and then the parts (4) to be sucked by the suction nozzle (14).
The tape feeder (7) or bulk cassette feeder (8) that supplies the parts is moved along the linear guide (12) and stopped at a part suction position.

Next, the three bulk cassette feeders shown in FIG.
8), and if the current position of the feed table (6) is as shown in Figure 2, the CPU (85)
Since "0" is stored in the memory (88), the motor (10 ) to move the supply stand (6).

As the supply table (6) moves, the next mounting head (15) moves to the suction station due to the intermittent rotation of the turntable (13), but when the supply table (6) stops, the feed lever cam (66 ), the feed swing lever (68) swings in the counterclockwise direction in FIG. 7 about the support shaft (67), and the feed lever (64) is biased by the tension spring (69) as shown in FIG. Move to the left and swing arm (60)
is swung leftward in FIG. 7 against the tension spring (63).

Then, the compression spring (59) moves the rack as shown in FIG.
And a guide roller (57) and a guide body (
58), and the pinions (43) and (44) are rotated. As a result, the ratchet bracket (46) (
47), the ratchets (51) and (52) rotate the ratchet wheels (48) and (49), respectively. At the position where the ratchet wheels (48) (49) have rotated 90 degrees, the rack (56) is stopped by a stopper (not shown), the ratchet wheels (48) (49) stop rotating, and at this position the ratchet lock pawl ( 53 and 54 engage with the wheel grooves (50) of the ratchet wheels (48) and (49), respectively. In this way, the ratchet wheel (
Rotor shafts (40) and (41) to which 48 and 49 are respectively attached
) rotates 90 degrees, the rotor (34) rotates 90 degrees clockwise in FIG. is moved to the chip suction station, and the component (
4) slides on the component placement surface (36) and moves to the station.

Next, when the feed lever (64) returns to the left side in FIG. 4, the swing arm (60) returns to the pinion (43).
(44) and the ratchets (51, 52) also return to their original positions, but the ratchet wheels (48, 49) do not rotate because they are locked by the ratchet lock pawls (53, 54), respectively. (34) and (35) maintain the rotated positions.

At this time, at each chip separation station of the rotor (34) (35), the groove (
33) Storage is performed inside.

That is, the fitting pin (80) reaches the right end of the elongated hole (79) due to the swinging of the swing arm (60) due to the movement of the feed lever (64) to the right in FIG. 60) swings, the lever (76) moves to the right in FIG. Then, the lever (77) moves to the support shaft (
The cam follower (81) swings around the pin (78) as a fulcrum.
75) to the left side in FIG. 1 against the compression spring (82). As a result, the ball (74) is compressed by the ball compression spring (7).
3) and is pushed away from the sealing (72) to open the air passage (31).

Then, the parts (4) aligned in the chutes (25) and (26) are discharged from the chute air supply holes (29 and 30), respectively, when the rotors (34 and 35) stop. The first part (4) is pushed by compressed air.
is extruded and stored in the groove (33) of each chip separation station.

On the other hand, chamber air supply holes (28) (29)
) and the chute air supply holes (29) and (30) at the same time, compressed air blows out from the second chambers (23) and (24).
), the feed lever (64) returns to the left in Fig. 1, and when the swing arm (60) returns, the pin (75) returns to the right and releases the ball (74). ) is in close contact with the seal ring (72), and the air passage (
31) is closed. Then each chamber (23) (
The parts (4) that have been blown apart in 24) fall, and a portion of them enters the respective chutes (25) and (26). The parts (4) that entered this chute (25) (26)
), the air supply holes (29) (
Since the part (4) is missing between 30), it slides down the chutes (25) and 26 due to its own weight, aligns itself in the chutes (25 and 26), and moves to the next rotor (34).
) (35) is provided for the discharge of compressed air when rotating.

[0047] A rotor (35) is located at the component suction position.
Since the chip suction station is located, the suction nozzle (14) suctions and takes out the chip part (4) from the rotor (35), and the CPU (85) reads the part taking out memory (
88).

Next, at the suction station, the mounting head (15) having the nozzle (14) that has suctioned the component (4) is moved to the next stop position by the intermittent rotation of the turntable (13), and is moved to the next stop position. The mounting head (15) moves to the suction station.

[0049] Next, if the type of part (4) to be taken out next is supplied by the same bulk cassette feeder (8), the CPU (85) will When the memory (88) is read and "2" is stored, the motor (10) is driven so that the chip suction station of the rotor (34) of the feeder (8) stops at the component suction position. (6) Move. That is, in the case of this embodiment, the supply table (6) is as shown in FIG.
It moves 8.5mm to the right of and stops.

Furthermore, since the data in the component extraction memory (88) is not "0", the CPU (85) excites the plunger (70) via the interface (89) and the drive circuit (90), and the engagement piece (71) is moved to the left side in FIG. The plunger (70) is activated when the rotational position of the feed lever cam (66) is such that the feed lever (64) is still held on the right side in FIG. 7 against the biasing force of the tension spring (67). During this period, the engagement piece (71) prevents the swing lever (68) from rotating in the counterclockwise direction in FIG.

In this way, the chip suction station of the rotor (34) stops at the component suction position and the feed lever cam (
Due to the rotation of the engagement piece (66), even though the feed lever (64) would normally move to the left in FIG.
71), the feed lever (64) does not move and the rotors (34) and (35) do not rotate. Also ball (74)
The air passage (31) also remains blocked, and after the previous discharge of compressed air, air passes through the air supply holes (29) and (30) while falling through the chutes (25) and (26). Even if there is a part (4) that is not installed, the chute air supply hole (
Since compressed air is not discharged from 29) and 30, it can pass through the chute air supply holes 29 and 30.

[0052] In this way, the suction nozzle (14) is attached to the rotor (
The component (4) is sucked and taken out from the groove (33) of the chip suction station (34), and the CPU (85) reads the memory (88) because the current data in the part removal memory (88) is not "0". At the same time, the plunger (70) is deenergized and the engaging piece (71) is returned to the right side in FIG. 7. At this time, the feed lever cam (66) has rotated to a position that moves the feed lever (64) to the right side in FIG. 7, and the feed lever (64) is held at this position.

Next, if the type of component (4) to be taken out next is also supplied by the same bulk cassette feeder (8), the CPU (85) reads the memory (88) and stores "0". ” is stored, the rotor (34) with the smaller moving distance “0” is selected among the two rotors (34) and (35), and the supply table (6) is kept stopped. When the next mounting head (15) rotates to the suction station, the feed lever (64) rotates as described above due to the rotation of the feed lever cam (66) as shown in FIG.
to the left side and swing the swing arm (60), the rotors (34) and (35) rotate in the same manner as described above, and the chip parts (4) are placed in the grooves (33) of the respective chip suction stations. ) is supplied.

At this time, the air passage (31) is connected to the ball (7).
4) is opened by being pressed by the pin (75),
Chute (25) (26) after the previous compressed air discharge
The chute (25) (including the part (4) that slid down inside)
The parts (4) aligned in the air supply hole (26)
9) The air discharged from (30) causes the chute (
25) is pushed toward the exit side of (26), and the leading part (4) is stored in the groove (33) of the chip separation station. Also, the chute (25) of the second chamber (23) (24)
) (26) Parts that were stuck near the entrance (4)
are blown loose by compressed air from the air supply holes (27) and (28) in the same manner as described above.

Next, the suction nozzle (14)
4) Pick up the part (4) of the chip pick-up station,
The CPU (85) stores "1" in the memory (88).

Next, if the type of component (4) to be taken out next is supplied from another tape feeder (7), the supply stand (6) The suction nozzle (14) of the mounting head (15) moves to stop at that position and then rotates to suction the component (4).

Next, if the type of component (4) to be taken out next is from the center feeder (8) of the bulk cassette feeders (8) in FIG. Since the memory (88) of (8) is read and "1" is stored instead of "0", the corresponding feeder (
8) The supply stand (6) is moved so that the rotor (35) stops at the component suction position.

[0058] Then, as mentioned above, the plunger (70)
is excited, and the rotors (34) and (35) do not rotate. When the component (4) in the chip suction station of the rotor (35) is attracted to the suction nozzle (14), the memory (88) is "0" is stored and the excitation of the plunger (70) is cut off.

As described above, the chip component (4) is attracted to the suction nozzle (14) each time the mounting head (15) rotates intermittently, and moves to the stop position of the next intermittent rotation. The intermittent rotation of the table (13) causes the chip parts (4
) When the suction nozzle (14) that is suctioning the part (
4) positional deviation is recognized.

Next, when the suction nozzle (14) that is suctioning the part (4) stops at the angle correction station, the nozzle rotation roller (1
8), the suction nozzle (14) is rotated in the θ direction to correct the positional deviation of the rotation angle of the component (4).

Next, when the suction nozzle (14) that is suctioning the component (4) stops at the mounting station, the XY table (1) on which the printed circuit board (5) is placed is moved by the X-axis motor (
2) and the rotation of the Y-axis motor (3), the recognition device (17
) is corrected and moved, and the component (4) is mounted at a predetermined position on the printed circuit board (5).

In this embodiment, a feed lever (64) is provided that can swing the swing arm (60) regardless of which of the chip suction stations of the rotor (34) and the rotor (35) is in the component suction position. However, for example, the rotor (
The swing arm (60) can only swing when the chip suction station (34) is in the component suction position, and the rotor (
35) cannot be swung when they are in the same position, the following can be done.

That is, when the component (4) is no longer attracted by both the chip suction stations of the rotor (34) and (35), the chip suction station of the rotor (34) is stopped at the component suction position and the feed lever is moved. (64) is moved to swing the swing arm (60) to supply the component (4) to the chip suction stations of both rotors and cause the component (4) to be suctioned.

[0064] Next, the parts (
4), the chip suction station of the rotor (35) is stopped at the component suction position and is suctioned.

In this case, even if the feed lever (64) reciprocates, it does not hit the swing arm (60), so the rotors (34) and (35) do not rotate, and the pin (7
5) does not move and the air passage (31) also remains closed, so there is no need to provide a plunger (70). Also,
The CPU (85) determines if there is no component (4) in both chip suction stations of the rotor (34) and (35).
In order to discriminate between the two states of being taken out from the rotor (34) and being present in the rotor (35), a discrimination memory is provided.
It is sufficient to store "0" and "1" in correspondence with the two states for each suction operation, read the contents of the memory, and determine which rotor to move to as described above.

Furthermore, in this embodiment, the bulk case (20
) is slightly smaller than the width of the bulk cassette feeder (8), so they were installed back and forth as shown in Figure 1, but the width of the case (20) ) may be installed side by side in the moving direction of the supply stand (6).

Furthermore, in this embodiment, the bulk case (20
) is configured to be attached to each chute (25) and (26), for example, the second chamber (23).
Two chutes are connected to each other at the bottom of the chutes, each chute is provided with a supply hole for discharging compressed air, and the aligned parts (4) are pushed out to the chute exit side. It is also possible to install only one.

Furthermore, in this embodiment, a plunger (70
), but an air cylinder or the like may be used instead, and the plunger (70) supports the lower part of the support shaft (67) of the feed swing lever (68) shown in FIG. The upper part of the shaft (67) may be pressed, or the feed lever (64) may be pressed directly to the right side in FIG.

Furthermore, the position of the chip suction station of the rotor (34) is on the straight line connecting the two locate pins (19), and the parts (
4) is adsorbed by the suction nozzle (14), which is also on the straight line connecting the two locating pins (not shown) of the tape feeder (8), so these positions are lined up on the supply table (6) at a pitch of 17 mm. The 17mm is the supply stand (6
) serves as a reference when moving. The position of the chip suction station of the rotor (35) is 8.5 mm away from this position, which is half of 17 mm, and this distance is added or subtracted to supply the rotor (35) to the component suction position. The moving distance of the table (6) will be calculated. Therefore, if the position of the rotor (34) is as described above, the position of the rotor (35) can be freely selected even if it is not 8.5 mm away from the position of the rotor (34), and when calculating the moving distance, the distance should be taken into consideration. In this way, the sizes of the rotors (34) and (35) can also be changed.

However, some tape feeders (7) are larger than those mentioned above and can be installed at a pitch of 1.5 times the 17 mm, so in order to install them efficiently, the
．． Locate pin (19) to supply table (6) at 5mm pitch
When drilling a hole, the standard for movement is 8.5 mm, but in this case, the distance between the rotors (34) and (35) is 8.5 mm.
5 mm is convenient. Conversely, if the holes for the locate pins (19) are drilled at a pitch of 8.5 mm,
It is also possible to widen the bulk cassette feeder (8) to a width of 25.5 mm to increase the spacing and size of the rotors (34) and (35).

Furthermore, the number of rotors is not two but three or more, and one or more racks are provided to intermittently rotate the third and subsequent rotors so that they reciprocate together with the rack (56). Therefore, three or more may be rotated intermittently at the same time. In this case, the chute and the chute air supply hole may also be provided corresponding to the rotor.

Furthermore, the pitch of the locate pin is 8.5.
If the pitch is not mm, this embodiment may be applied based on that pitch. Furthermore, in this embodiment, the rotor (34) (35
) is driven by a drive source that rotates the turntable (13), so it uses a plunger (70) to prevent it from being activated even by intermittent rotation of the turntable (13). However, instead of rotating the turntable (13), the feed lever cam (66) is rotated by an independent drive source, a ball screw is rotated, or an air cylinder or the like is used to rotate the feed lever cam (66). 64) to reciprocate, the CPU
(85) controls this drive source to control the turntable (13).
) can be prevented from reciprocating even if the feed lever (64) rotates intermittently.

Furthermore, in this embodiment, the swing arm (6
Both the rotation of the rotor (34) (35) and the reciprocating movement of the valve opening/closing pin (75) are linked by the swinging of the valve opening/closing pin (75). Alternatively, another mechanism similar to the reciprocating mechanism of the feed lever (64) may be provided, and the reciprocating movement of the feed lever may be synchronized with the rotation of the rotors (34) and (35). ) The pin (75) may be reciprocated by a drive source different from the drive source that drives the pin (75).

[0074]

As described above, according to the present invention, the same chip components are simultaneously supplied from multiple chutes, and the chip components in the chip component storage chamber are blown up in synchronization with this. This is done after all of the components have been taken out, so sufficient time is secured for the chip parts to fall into the chute and line up, and the number of chip parts lined up in the chute does not decrease and the time required to take out the parts is reduced. The interval can be shortened.
