[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip component supply device which is detachably mounted on a feeder bank of a chip component automatic mounting machine for an electronic circuit board and supplies chip components one by one.

[0002]

2. Description of the Related Art As a chip component supplying device for supplying a chip component to a chip component mounting machine, there is conventionally a tape feeder type chip component supplying device 1 as shown in FIG.

This chip component supply device 1 supplies a chip component 4 taped and packaged to a tape 3 having a feed hole 2 as shown in FIG. Here, the chip component 4 has a rectangular shape, and its short side is parallel to the tape feeding direction.

The tape 3 is rolled and attached to the reel hook 5 in the chip component supplying apparatus 1 of FIG. 6, passes through the tape groove 6, and the cover film is peeled off below the upper cover 7. It is supplied to a pickup point 9 which is opened and closed by the shutter 8. Reference numeral 10 in the figure denotes a tape holder for winding the cover film.

The chip component supplying apparatus 1 is mounted on a feeder feeder bank 11 of a chip component mounting machine (not shown) as shown in FIG. 4, and a head 12 of an air cylinder (not shown) at the mounting position. By pushing up the knock lever 13 at the lower end of the tip, the tape 3 is intermittently fed by the pitch of one chip component 4.

Reference numeral 14 designates a lock shaft 15 of the feeder bank 11 of the supply unit when the chip component supply apparatus 1 is mounted.
A lock holder for engaging and fixing the

At the time of mounting, the positioning pins 16 and 17 are fixed to the positioning holes 16A and 17 on the feeder bank 11 side of the supply section.
If it is pushed in according to A, the lock holder 14 engages with the lock shaft 15 on the side of the feeder bank 11 of the supply unit, and the mounting of the chip component supply device 20 on the feeder bank 11 of the supply unit is completed.

Head 12 on the feeder bank 11 side of the supply section
Is intermittently driven by an air cylinder to intermittently push up the knock lever 13 on the chip component supply device 20 side.

When the roller 13A side of the knock lever 13 is pushed up by the head 12, the knock lever 13 is swung counterclockwise in FIG. 2, which causes the free link 40 to move leftward in FIG. 2 against the spring 40B. Move to.

The dog 40C abuts and opens the pneumatic valve 44 by the leftward movement of the free link 40, so that compressed air passes through the pressure air pipe 46 and the air holes 32A, 3
2A is supplied.

Therefore, pressure air is jetted into the lane 30 from the air holes 32A, 32A, the chip component 22 in the lane 30 is sent out to the right in FIGS. One chip component 22 is pushed out from the outlet 30B of the lane 30.

On the other hand, the swing link 48 engaging with the knock lever 13 also drives the shutter 34 leftward in FIGS. 1 and 2 via the shutter link 52.

If the projection timing of the shutter 34 is matched just before the chip part 22 is pushed onto the pickup point 28, one chip part 22 is placed on the pickup point 28 below the shutter 34.
Is pushed out, and the shutter 34 is projected so as to cover the upper surface of the chip component 22. At this time, the tip of the shutter 34 prevents the chip component 22 from being blown off, and at the same time, the chip component 22 on the pickup point 28 prevents the next chip component 22 from being discharged.

Head 12 on the feeder bank 11 side of the supply section
Is returned downward, knock lever 13 and free link 4
0, the swing link 48 is returned to the state of FIG. 2 by the spring 40B that biases the free link 40.

Therefore, the dog 40C is separated from the pneumatic valve 44, the pneumatic valve 44 closes the pressure air line 46, and the shutter 34 is returned to the standby position as shown by the solid line in FIG. Top one chip part 2
2 is exposed, and the exposed chip component 22 is taken out by a suction pin 54 of a chip mounting machine (not shown).

By repeating the above operation, the chip components 22 are supplied one by one from the chip component supply device 20.

Here, when the chip component 22 is moved in the lane 30 in the right direction in FIG. 1 by the pressurized air ejected from the air holes 32A and 32B of the chip component feeding means 32, the front of the outlet 30B is reached. By passing through the curved portion 30A, the attitude of the chip component 22 is turned by 90 ° with respect to the straight portion in front of the curved portion 30A, so that the chip component 22 on the pickup point 28 is the tape feeder. The attitude is the same as that of the chip component supply device 1 of the type.

Therefore, in this embodiment, the posture of the chip component is set to 90 without using a complicated structure such as a chip component separating mechanism having a rotating index wheel.
° It can be converted and supplied to the chip component mounting machine.

In this embodiment, since the accuracy of supplying the chip component 22 to the pickup point 28 is determined only by the concave portion of the pickup point 28 continuous from the lane 30, it is hard to be influenced by the machine life and the like and is highly accurate. The chip component 22 can be fed onto the pick-up point 28.

Next, a second embodiment of the present invention shown in FIG. 5 will be described.

In the second embodiment, the chip component 22 is sent by compressed air in the first embodiment, whereas the chip component 22 is sent by vibration.

The chip part feeding means 54 in the second embodiment has a pair of leaf springs 54A for supporting the bulk case 24, the cassette 26 and the lane 30 so as to be swingable within the vertical plane with respect to the feeder base 36. And a solenoid device 54B which is disposed between the feeder base 36 and the lane 30 side and which vibrates when energized, and a dog 40C which is provided on the free link 40, for turning on / off the solenoid device 54B. Switch 5
4C and.

Since the other structure is the same as that of the first embodiment, the same portions are denoted by the same reference numerals as those in FIG. 2 and the description thereof will be omitted.

In the second embodiment, the knock lever 13 is driven by the head 12 on the feeder bank 11 side of the supply section.
Is pushed up and the free link 40 moves to the left, the dog 40C turns on the switch 54C, and the solenoid device 5
4B is vibrated vertically.

Since the lane 30 side is floatingly supported on the feeder base 36 by a pair of leaf springs 54A,
The spring 54A is swung in the vertical plane along the deformation direction,
As a result, the chip components 22 in the lane 30 are fed.

Since the drive mechanism of the shutter 34 and its operation are the same as those in the first embodiment, the description thereof will be omitted.
