[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component supply apparatus for supplying electronic components having no lead wires in a predetermined direction.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Application Publication No. 2004-214,643 discloses a device capable of supplying components having no lead wires (hereinafter simply referred to as components), for example, components such as a columnar inductor and a capacitor in a line in the longitudinal direction. Japanese Patent Application Publication No. Sho 62-280129 is known.

The supply device disclosed in the publication includes a chip storage room and a secondary storage room provided below the chip storage room via a gate, and is provided near an opening of a chip alignment hole. By intermittently ejecting pressurized air from each of the fumarole, the fumarole provided near the gate in the chip storage chamber, and the fumarole provided near the opening in the chip alignment hole, the chip storage chamber is discharged. Then, the chips in the secondary storage chamber are blown out, and among the blown out chips, the chips that match the openings are dropped into the chip alignment holes.

[0004]

In the above-described conventional supply device, the chips in the chip storage chamber and the secondary storage chamber are only blown out by intermittently ejecting pressurized air from each of the blowing ports. The probability of dropping the blown chips into the chip alignment holes is extremely low, and it takes a considerable amount of time before the parts are aligned and supplied because the compressed air cannot be continuously ejected. In addition, there is a disadvantage that the supply speed is low.

A component alignment groove to be received in a fixed direction and a portion corresponding to the lower end upper side of the component alignment groove on one side of the air chamber, so that it passes through the lower end upper side of the component alignment groove and collides with the other side surface of the air chamber. And a component conveying path provided below the air chamber and communicating with the lower end of the component alignment groove.

According to the above construction, the air continuously blown out from the air blowout hole provided on one side of the air chamber is caused to collide with the other side of the air chamber through the lower end of the component alignment groove. Most of the air flows upward along the collision surface, and can be circulated through a path that flows downward from the upper wall of the air chamber along the side surface on the side of the air outlet. The parts in the parts storage chamber are restrained from moving downward in the throttle passage position by the flow of air from the air chamber to the parts storage chamber, and are guided by the flow of air circulating in the air chamber to be fixed in the alignment alignment groove. In the direction of.

The second component passage 9 has a stopper 9a at the front end, and this portion is opened as an outlet 9b. In this embodiment, the second component passage 9 and the first component passage 7 constitute a component conveying passage.

Next, a component supply operation in the above-described electronic component supply device will be described with reference to FIGS.

First, an air supply source (not shown) connected to the air supply port 6b is operated to continuously blow air into the air chamber 3 from the air blow hole 6, and the parts are stored in the parts storage chamber 2 in the same state. Input D.

The air continuously blown out of the air blowout holes 6 is supplied to the component alignment grooves 5a as shown by solid arrows in FIG.
Collides with the other side surface of the air chamber 3 through the upper end of the lower end of the air chamber 3. Most of the air after the collision flows upward along the collision surface as shown in FIG. 5, and further circulates in a path flowing downward from the upper wall of the air chamber 3 along the side surface on the side of the air outlet 6.

However, even when the component D enters the component alignment groove 5a in a vertical or oblique direction, The direction of the part D can be corrected in parallel with the groove by the wind pressure of the circulating air hitting the protruding portion from the groove.

The above-described component aligning operation is sequentially performed on the component D waiting at the position of the throttle passage 4, and in practice, as shown in FIG. Enter in a line and line up. Even if the component D moves vertically or obliquely into the component alignment groove 5a in the state shown in FIG. 7 and moves downward, the component D will not move due to the wind pressure of the circulating air hitting the projecting portion from the groove.

Components D arranged in a line in the component alignment groove 5a
The first component passage 7 is moved by its own weight due to the flow of air from the component alignment groove 5a toward the first component passage 7.
Then, the component D moves along the second component passage 9 and the leading component D is sent to the outlet 9b.

The component D sent to the outlet 9b is taken out by a suction nozzle N as shown in FIG. 1, and the subsequent component D is sequentially fed to the outlet 9b after the component is taken out.

As described above, according to the above-mentioned electronic component supply device, the air blowing holes 6 provided on one side surface of the air chamber 3 are provided.

Most of the air after the collision flows upward along the collision surface, and is circulated downward along the side surface of the air chamber 3 from the upper wall of the air chamber 3 to the inside of the component storage chamber 2. Of the part D is restricted by the flow of air from the air chamber 3 toward the parts storage chamber 2 at the position of the throttle passage 4, and is guided by the flow of air circulating in the air chamber 3 to form the alignment groove 5a. In a predetermined direction.

That is, air is continuously blown from the air blowout hole 6 provided on one side surface of the air chamber 3 through the lower end upper side of the component alignment groove 5a so as to collide with the other side surface. In this way, a flow of air suitable for taking in parts can be formed, and the parts D in the parts storage chamber 2 can be efficiently inserted into the alignment and alignment groove 5a in a predetermined direction by using the flow of air. Can be promptly performed in a short time.

In the above-described embodiment, a cylindrical component is taken as an example. However, components having other shapes such as a prism and an ellipse can be supplied as long as they have no lead wire.
Further, the shape of the component alignment groove may be such that the groove width increases upward as indicated by 5 'in FIG. 8 so that the component can easily enter the component alignment groove.
