Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic component supply device that supplies electronic components having no lead wire side by side in a fixed direction.

[0002]

[Prior Art]

 An electronic component having no lead wire (hereinafter, simply referred to as component), for example, a component capable of supplying by arranging components such as a cylindrical inductor and a capacitor in a longitudinal direction is disclosed. No. 62-280129 is known.

The supply device disclosed in the above publication discloses a chip storage chamber for storing parts, a secondary storage chamber provided below the chip storage chamber via a gate, and the secondary storage chamber. It is equipped with a chip alignment hole formed at the lower end of the chamber and a fumarole provided in the secondary storage chamber. By intermittently ejecting air from the fumarole into the secondary storage chamber, the components inside the chamber The chip aligning holes receive some of the components that fall after the blowing and then supply the components from the lower end of the chip aligning holes.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional feeding device, since the components are only lifted up intermittently by the air ejected from the fumarole, the probability that the falling components are received by the chip alignment holes is extremely low, and Since it is not possible to continuously eject the liquid, it takes a considerable time for the parts to be aligned, and the supply speed is slow.

Further, since the passages for conveying the aligned parts are hermetically closed, it is difficult to eliminate the clogging of the parts in the passages. Also, the inclination of the parts in the passages is used as a conveying force. However, there is a problem that it is difficult to convey the aligned components to a desired position because the released air easily deteriorates.

The present invention has been made in view of the above circumstances, and an object of the present invention is to arrange electronic parts in a short time so that the supply can be performed quickly and the electronic parts can be conveyed without trouble. It is to provide a supply device.

[0007]

[Means for Solving the Problems]

 To achieve the above object, the present invention provides a component storage chamber for storing a large number of leadless electronic components having a predetermined shape, a lower end of the component storage chamber and a lower end of the storage chamber, and a throttle passage. Air chamber that communicates with each other, a component alignment groove that is installed diagonally downward in the air chamber to receive electronic components in a certain direction, and a component alignment groove that is provided on the side surface of the air chamber and is orthogonal to the alignment groove above the lower end of the component alignment groove. Air-blowing hole that blows air in the direction of, the component-transporting passage that is provided below the air chamber and communicates with the lower end of the component alignment groove, and the window hole that is formed along at least a part of the component-transporting passage. The above constitutes an electronic component supply device.

[0008]

[Action]

 The electronic component supply apparatus according to the present invention is used by inserting a desired electronic component into the component storage chamber in a state where air is blown into the air chamber from the air outlet.

The electronic components that have been put into the component storage chamber are restrained from moving downward at the throttle passage position due to the wind pressure of the air circulating in the air chamber.

The electronic component standing by at the throttle passage position is received in the component alignment groove while being guided by the flow of air circulating in the air chamber and at the same time having its direction corrected. This alignment operation is sequentially performed for the electronic components waiting at the throttle passage position. The electronic components arranged in the component alignment groove in a certain direction move along the transport passage by the flow of air from the alignment groove toward the component transport passage.

Further, since a window hole is formed in the component transfer passage along the transfer passage, even if a component clogging occurs in the transfer passage, it can be easily eliminated through the window hole. There is also a good escape of the air used as the carrying force.

Next, the component supply operation in the above-described electronic component supply device will be described with reference to FIGS. 6 to 8.

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

The air blown out from the air outlet holes 6 collides with the other side surface, and most of the air after the collision flows upward along the side surface as shown in FIG. The air flows downward along the side surface of the air outlet 6 side and circulates. The air that has circulated in the air chamber 3 exits from the window hole 14 through the throttle passage 3 and the component storage chamber 2, and also through the first and second component passages 7 and 12.

As shown in FIG. 6, the component D put in the component storage chamber 2 has a wind pressure of the air circulating in the air chamber 3 and an air flowing from the throttle passage 3 to the component storage chamber 2. Due to the flow, the downward movement of the throttle passage position 4 is suppressed.

As shown in FIG. 7, the part D standing by at the position of the throttle passage 4, especially the part D near the guide surface 5b of the guide rail 5, is guided by the flow of the air entrained in the same part and is guided by the guide surface. 5b enters into the component alignment groove 5a. In the same figure, the state in which the component D is inserted into the component alignment groove 5a in parallel is shown. However, even when the component D is vertically or obliquely entered in the component alignment groove 5a, the wind pressure applied to the protruding portion of the component D causes It is possible to correct the direction in parallel.

The above-described alignment action is sequentially performed on the parts D standing by at the position of the throttle passage 4. In practice, as shown in FIG. Line up in the direction. Even if the component D moves downward while vertically or obliquely entering the alignment groove 5a in the state of FIG. 8, the component D is blown away by the strong wind pressure at the position of the air-blowing hole 6 and returned to the position of the throttle passage 4. be able to.

The parts D lined up in the part alignment groove 5a are moved to the first part passage 7 and the second part passage 12 while being accompanied by their own weight sliding due to the flow of air from the alignment groove 5a toward the first part passage 7. The part D at the tip passes under the pressing piece 25a, is sent to the take-out port 12a, and abuts on the stop plate 15.

When the lever 22 is pushed down here, the rotary plate 24 rotates in the clockwise direction in FIG. 1, and the rotation causes the convex portion 24c to be disengaged from the receiving piece 25b of the component holding plate 25. 25a descends and the subsequent part D is pressed and held at the same position (see the chain double-dashed line in FIG. 4). At the same time, the holder 26a of the pressing rod 26 is pressed forward by the rotation of the rotary plate 24, whereby the stop plate 15 and the receiving pieces 15a, 16b of the pop-out prevention plate 16 are pushed at the front end of the pressing rod 26. Each of them is pressed forward and bent, and the stop plate 15 separates from the component D, and the bent portion of the pop-out prevention plate 16 comes out of the outlet 12a (see a chain double-dashed line in FIG. 5).

The part D at the outlet 12a is taken out by the suction nozzle N as shown in FIG. When the lever 22 is released after the parts are taken out, the receiving piece 25b of the part holding plate 25, the stop plate 15 and the pop-out prevention plate 16 are returned to their original positions, and the succeeding part D is taken out of the take-out port 12a. Sent to.

As described above, in the present embodiment, the air blown from the air-blowing holes 6 is circulated in the air chamber 3 to reduce the downward movement of the component D in the component storage chamber 2 to the fourth position of the throttle passage. It is possible to sequentially guide the parts D standing by at the position of the throttle passage 4 into the part alignment groove 5a in the air chamber 3 while arranging them in a line in the longitudinal direction while restraining the position of the throttle passage 4 in a continuous direction. The parts D can be aligned and supplied quickly in a short time.

Further, since the window hole 14 is provided on the side surface of the second component passage 12, even if the component D is clogged in the passage 12, it is possible to easily eliminate it through the window hole 14. .. Moreover, the presence of the window hole 14 makes it possible to maintain good escape of the air used as the carrying force, so that even if the parts incline in the passage 12 or the like, the parts after alignment are taken to the take-out position. Can be transported smoothly.

Furthermore, since the take-out port 12a is covered by the upper bent portion of the pop-out prevention plate 16, when the part D moves vigorously toward the take-out port 12a or when the follow-up part D presses the take-out port 12a. Even if a load is applied to the parts D standing by, it is possible to prevent the parts D from popping out or tilting.

Furthermore, by pressing down the lever 22 at the same time as the parts are taken out, the succeeding parts D are pressed and held by the holding pieces 25a of the parts holding plate 25, and the stop plate 15 is moved to the taking-out position with the position displaced. Since a certain part D can be taken out, when taking out the part D, the subsequent part D is not hooked and tilted by the part D, and the takeout resistance can be greatly reduced.

In the above embodiment, a cylindrical part is taken as an example. However, if the part does not have a lead wire, a part having another shape such as a prism or an ellipse may be a target for supply. it can.

[Effect of the device]

 As described above in detail, according to the present invention, the air blown from the air outlet is circulated in the air chamber to suppress the downward movement of the component in the component storage chamber at the throttle passage position. The parts standing by at the throttle passage position can be sequentially guided into the parts alignment groove in the air chamber and arranged in a line in the longitudinal direction, enabling continuous air blowing and shortening the parts alignment and supply. It can be done quickly in time.

Further, since the window hole is provided along the parts conveying passage, even if the parts are clogged in the passage, it is possible to easily eliminate the parts through the window hole and the existence of the window hole. As a result, the air used as the conveying force can be kept satisfactorily released, so that even if the components are inclined in the passage, the aligned components can be smoothly conveyed to the take-out position. ..
