DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply apparatus used for a component mounting machine for mounting components such as electronic components on a printed circuit board.

[0002]

2. Description of the Related Art In recent years, when electronic components are mounted on a printed circuit board, there has been a demand for a high-speed electronic component supply.

Hereinafter, a conventional component supply device will be described. As shown in FIG. 4, the supply table 16 to which a plurality of parts cassettes 15 on which parts are mounted is mounted is driven in the direction shown by the arrow X, and performs positioning so that necessary component tapes come to a predetermined position. After the supply table 16 stops, the feed lever 17 descends and the parts cassette 1
In contact with the lever 18 of No. 5, the shutter of the component tape covering the component is opened, and the nozzle 19 is lowered to the suction position to suck and raise the component. Feed lever 17 lowered
After being lifted and separated from the lever 18, the supply table 16 is driven again for the next component selection.

In this configuration, the vertical movement of the feed lever 17 as shown by the arrow G is driven from one drive source in order to synchronize with the turning movement of the nozzle 19 shown by the arrow H and the vertical movement shown by the arrow A. ing. Therefore, even when the supply table 16 is not driven, the feed lever 17 and the nozzle 19 move up and down at the same timing.

[0005]

However, in the above-described conventional configuration, a series of operations such as opening and closing of the shutter covering the component, suction of the component, and feeding of the component tape are all performed within the time when the supply table 16 is stopped. Therefore, there is a problem that the supply of parts cannot be speeded up.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a component supply apparatus in which component supply is speeded up.

[0007]

In order to achieve this object, a component feeder according to the present invention comprises a drive roller rotatable along a moving direction of a component feeder and movable vertically.
A lever portion that can be directly moved by a driving roller, a transmission portion that transmits the drive of the lever portion, a feeding unit that sequentially sends parts by driving from the transmission portion, and an opening in a covering portion of a predetermined component by driving from the transmission portion. This is a configuration provided with a shutter unit that enables the above.

[0008]

In this configuration, the drive roller operates while the component supply unit is moving, the lever is driven to open the shutter unit, and the suction nozzle sucks the component immediately after the movement of the component supply unit is completed. Then, after the component supply unit starts the next movement, the drive roller operates to perform the sequential feeding of the component and the closing of the shutter unit via the lever unit and the transmission unit.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a drive roller 3 rotatable perpendicular to the moving direction of the component supply unit 1 is disposed above the parts cassette positioned by the positioning pins 2 in the component supply unit 1. . The linearly movable lever portion 4 comes into contact with the drive roller 3. A link lever 6 is rotatably connected to a distal end of a transmission portion 5 that transmits the drive of the lever portion 4 by a pin 7, and the link lever 6 and the ratchet wheel 8 are rotatably fixed by a pin 9. The pin 10 of the link lever 6 is connected to a shutter section 11 that covers the component mounted on the component tape. A ratchet pin 12 and a stopper lever 13 for preventing reverse rotation are engaged with the uneven portion on the outer peripheral portion of the ratchet wheel 8. Reference numeral 14 denotes a suction nozzle that drives the device up and down as indicated by an arrow A for sucking components.

The operation of the component supply device configured as described above will be described below. The lever portion 4 is driven by coming into contact with the drive roller 3, and the pin 7 of the link lever 6 swings about the pin 9 via the transmission portion 5,
The link lever 6 rotates.

With the rotation of the link lever 6, the pin 10
The shutter 11 connected to the pin 10 opens the cover of the component, and the suction nozzle unit 14 descends to suck the component, and then moves up.

Further, the ratchet pin 12 also rotates around the pin 9 with the rotation of the link lever 6, and slides on the uneven portion around the ratchet wheel 8.

Next, in the returning step of the drive roller 3, the transmission portion 5 and the link lever 6 are driven, the ratchet pin 12 is caught on the uneven portion around the ratchet wheel 8, and the ratchet wheel 8 rotates around the pin 9. At the same time, a wheel (not shown) integrated with the ratchet wheel 8 also rotates, and a component tape containing components is fed by a plurality of pins around the wheel. Pin 10 at the same time
The shutter unit 11 connected to is also moved to cover the components.

The operation in which the lever unit 4 is driven by contact with the drive roller 3 will be described below. As shown in FIG. 2A, a plurality of levers 4 reciprocating in a direction indicated by an arrow B are provided with a predetermined width, and are separated from the levers 4 by a certain distance and are indicated by an arrow C. Forward and backward, and rotate in the direction indicated by arrow D. A drive roller 3 is provided. As shown in FIG. 2B, the driving roller 3 is driven together with the movement of the component supply unit 1, and the edge of the lever unit 4 driven in the direction indicated by arrow F passes through the rotation center of the driving roller 3. Touch Thereafter, while the component supply unit 1 moves, the drive roller 3 rotates in the direction shown by the arrow D, and FIG.
The driving is ended as shown in FIG. The same operation is performed in the return stroke. FIG. 3 shows a timing chart of each operation of the above-described component supply unit 1, drive roller 3, and suction nozzle 14. Drive roller 3
The stroke of (1) is provided with a switching unit (not shown) that can be switched by previously storing the storage pitch of the parts in the device, and switching can be performed according to the storage pitch.

As described above, according to the present embodiment, the operation of the drive roller 3 can be almost completed during the moving time of the component supply unit 1, so that the speed of component supply can be increased. Further, by switching the drive stroke in accordance with the component storage pitch, the impact force applied to the parts cassette can be reduced, which is suitable for speeding up the supply of components.

[0017]

As is apparent from the above description of the embodiment, the present invention provides a drive roller rotatable along the moving direction of the component supply unit and vertically movable, and a linearly movable drive roller. A lever unit, a transmission unit that transmits the drive of the lever unit, a feeding unit that sequentially sends parts by driving from the transmission unit, and a shutter unit that enables opening of a covering part of a predetermined component by driving from the transmission unit. With such a configuration, it is possible to realize an excellent component supply device in which component supply is speeded up.
