Abstract

PROBLEM TO BE SOLVED: To provide an electronic component supplying apparatus which can make a stable and accurate transportation of components by air suction. SOLUTION: Suction holes 6f which allows an air suction force to work inside a transportation path 6a so that electronic components EC may be transported in the transportation path 6a towards a stopper 7 are formed at the sides of the forefront electronic component EC in such a state as abutted by the stopper 7. Therefore, there is nothing to interrupt the air flow between the transportation path 6a and the suction holes 6f, and also there is nothing to narrow an air channel. In other words, such an air flow that the air in the transportation path 6a may be directly sucked into the suction holes 6f can be generated by suppressing the generation of such phenomena as a turbulance, pressure loss, change in air flow rate, or the like, in the air flow from the transportation path 6a to the suction holes 6f and thereby transporting the components by air suction smoothly.

The operation of the apparatus according to the first embodiment will now be described with reference to FIG.
This will be described with reference to FIG.

The device according to the first embodiment, in the state where thousands to tens of thousands of electronic components EC are stored in bulk in the component storage room 2a, as shown in FIGS. The operation of pushing down the one roller 9a by a predetermined stroke and thereafter returning the operation lever 9 is performed in a predetermined cycle, for example, 0.
By repeating the process in about one second, the intended parts supply is performed.

When the first roller 9a of the operating lever 9 is pushed down, as shown in FIG. 9, the operating lever 9 rotates counterclockwise, and the second roller 9b of the operating lever 9 causes the inclined surface of the drive lever 10 to rotate. 10a is pushed downward, and the drive lever 10 rotates counterclockwise. When the depression of the first roller 9a of the operation lever 9 is released, as shown in FIG. 10, the operation lever 9 rotates in the opposite direction by the urging force of the fourth coil spring CS4 to return, and interlocks with this rotation return. As a result, the drive lever 10 rotates in the opposite direction by the biasing force of the first coil spring CS1 and returns.

When the drive lever 10 rotates in the counterclockwise direction, the movable pipe 4 rises a predetermined stroke while compressing the first coil spring CS1, and the rising of the movable pipe 4, as shown in FIG. The electronic component EC on the upper side is lifted upward, and the electronic component EC in the storage room 2a is subjected to a stirring action.
C is inserted one by one in the length direction into the upper end of the inner hole of the fixed pipe 3 using the inclination of the guide surface 4a or directly. Also,
When the drive lever 10 returns, the movable pipe 4 is lowered from the raised position by the urging force of the first coil spring CS1, and the electronic component EC on the upper side of the movable pipe 4 is lowered by the lowering of the movable pipe 4, so that the storage chamber 2a Electronic components E in
C is subjected to the same stirring action as described above, whereby the storage components EC enter the upper end of the inner hole of the fixed pipe 3 one by one in a lengthwise direction by utilizing the inclination of the guide surface 4a or directly.

The electronic component EC that has entered the inner hole of the fixed pipe 3 as the movable pipe 4 moves up and down moves down the inner hole due to its own weight, enters the transport passage 6a, and moves through the curved portion by its own weight. The posture is changed from portrait to landscape and enters the horizontally long part. Since both the curved portion and the horizontally long portion of the transport passage 6a have a rectangular cross section, the directions of the four side surfaces of the electronic component EC except for both longitudinal end surfaces are corrected mainly when passing through the curved portion, and When entering, it is almost aligned with the four inner surfaces of the horizontally long part.

On the other hand, when the first roller 9a of the operating lever 9 is pushed down, as shown in FIG.
The rod 12a of the air cylinder 12 connected to the operation lever 9 retreats by a predetermined stroke in conjunction with the rotational displacement of. At this time, since the rear side of the control valve 13 serves as an exhaust port, air is discharged to the outside as shown by a broken arrow with the retraction of the rod 12a.

When the depression of the first roller 9a of the operation lever 9 is released, as shown in FIG. 10, the rod 12a of the air cylinder 12 advances from the retracted position in conjunction with the return of the rotation of the operation lever 9. At this time, since the front side of the control valve 13 serves as an intake port, the air suction force is generated by the advancement of the rod 12a via the air tube 14 and the tube connector 15 in the two suction holes 6 of the passage block 6.
Acts on f. Incidentally, this air suction force is not generated at the same time when the rod 12a of the air cylinder 12 starts to advance, but actually starts to act immediately after the advance is completed.

The component outlet 6b and the recess 6c of the passage block 6 are covered by the shutter 8, and the transfer passage 6
When the air suction force acts on the two suction holes 6f in a state where the front end opening of the a is closed by the component stopper 7, the air in the transport passage 6a is sucked into the two suction holes 6f, and the broken line in FIG. As shown by, an air flow is generated in the transport passage 6a toward the upper end openings of the two suction holes 6f. As a result, the electronic component EC that has entered the horizontally long part of the component passage 6a is drawn in by the air flow and is transported forward in an aligned state in the transport passage 6a. As shown in FIG. The EC contacts the component stopper 7 and is attracted by the magnetic force of the permanent magnet MG.

On the other hand, when a predetermined time elapses after the pressing of the first roller 9a of the operating lever 9 is started, in other words, immediately before the pressing operation is completed, as shown in FIG. The third roller 9c abuts on the rear end of the control hole 11c of the drive plate 11, and thereafter, the drive plate 11
It retreats by a predetermined stroke against the urging force of the coil spring CS5. When the drive plate 11 is retracted, FIGS.
As shown in FIG. 5, the shutter 8 connected to the drive plate 11 retreats by a predetermined stroke, whereby the opening 8b of the shutter 8 matches the concave portion 6c of the passage block 6, and the component outlet 6b is exposed. When the shutter 8 retreats, as shown in FIGS. 14 and 15, the slope of the projection 8 c of the shutter 8 becomes the curved surface portion 7 a of the component stopper 7.
And the curved surface portion 7a is pushed to the left, thereby
The component stopper 7 rotates a small angle in the clockwise direction, for example, about 3 degrees, against the urging force of the third coil spring CS3, and the surface of the component stopper 7 on the permanent magnet side becomes the transport passage 6a.
The front end opening is opened apart from the front end opening of the front end.

The electronic components EC are lined up in the transport path 6a in an aligned state, and the first electronic component EC is placed in the component stopper 7.
When the component stopper 7 rotates in the clockwise direction in a state of being sucked, the leading electronic component EC slightly moves forward together with the component stopper 7 as shown in FIGS. The leading electronic component EC is separated from the subsequent electronic component EC. By the way, the first electronic component EC is shown in FIG.
And in the state shown in FIG. 15, it is taken out from the component outlet 6b by the suction nozzle or the like.

When the depression of the first roller 9a of the operation lever 9 is released, as shown in FIG. 10, the drive plate 11 is advanced by the urging force of the fifth coil spring CS5 in conjunction with the return of the rotation of the operation lever 9. To return. With the return of the drive plate 11, the shutter 8 connected to the drive plate 11 is returned, whereby the opening 8b of the shutter 8 is disengaged forward from the recess 6c of the passage block 6, and the component outlet 6b and the recess 6c are again opened. While being closed, the curved surface portion 7 of the component stopper 7 by the projection 8c
a is released, the component stopper 7 rotates in the reverse direction and returns by the urging force of the third coil spring CS3, and the front end opening of the transport passage 6a is closed again.

That is, by performing an operation of rotating the operation lever 9 by a predetermined angle and returning it, the movable pipe 4 is moved up and down to feed the electronic component EC in the component storage chamber 2a into the transport passage 6a in a predetermined direction. it can. When rotating the operation lever 9 by a predetermined angle,
b and release the first electronic component EC to the subsequent component EC
When the operation lever 9 returns, the electronic component EC sent to the transport path 6a can be transported forward by air suction.

As described above, according to the device of the first embodiment,
A suction hole 6f for applying an air suction force to the inside of the transport passage 6a so that the electronic component EC in the transport passage 6a is transported toward the component stopper 7 is formed in the leading electronic component EC.
Is provided at the side position of the leading electronic component EC in a state in which it comes into contact with the component stopper 7, so that there is no portion serving as an air flow barrier between the transport passage 6a and the suction hole 6f.
In addition, there is no portion that restricts the air flow path. That is,
Since the air flow in which the air in the transport passage 6a is directly sucked into the suction holes 6f can be generated,
It is possible to suppress the occurrence of phenomena such as turbulence, pressure loss, and flow rate fluctuation in the air flow from the conveyance passage 6a to the suction hole 6f, and to perform the component conveyance by the air suction extremely well.

Further, since two suction holes 6f are provided symmetrically on both sides of the leading electronic component EC in a state of contacting the component stopper 7, a uniform air flow is formed in the transport passage 6a. Thus, the above-described component conveyance can be performed smoothly.

Further, since a part of the upper end opening of the two suction holes 6f is provided so as to appear on both the left and right sides of the bottom surface of the transport passage 6a, two suctions are performed by the leading electronic component EC contacting the component stopper 7. The upper end opening of the hole 6f is not closed.

Further, since the two suction holes 6f are provided so as to be located forward of the longitudinal center of the first electronic component EC in a state where the two suction holes 6f are in contact with the component stopper 7, the first electronic component EC is provided. Can be restrained from moving forward more than necessary due to inertia, and the impact when contacting the component stopper 7 can be reduced.

Further, the front end opening of the transport passage 6a is closed by the component stopper 7, and the component outlet 6b
Is simply closed by the shutter 8, so that air leaks from the boundaries between the members can be suppressed as much as possible, and the suction air can be effectively used for conveying parts.

Further, since the air cylinder 12 is used as an air suction source for carrying parts, and the air cylinder 12 is mounted on the frame 1 and operated by the operation lever 9, the air cylinder 12 is used for air suction. The apparatus itself can be configured simply and inexpensively without the need for a large suction source such as a vacuum pump and air piping from the suction source.

Further, the leading electronic component EC in the transfer passage 6a is attracted to the component stopper 7 by the magnetic force of the permanent magnet MG, and when the component outlet 6b is opened, the leading electronic component EC is displaced by the component stopper 7. Part E
C can be separated from the succeeding component EC, so that the leading electronic component E can be separated from the component outlet 6b by a suction nozzle or the like.
When taking out C, it is possible to prevent the electronic component EC from interfering with the succeeding component EC and perform the component taking-out operation satisfactorily.

In the first embodiment described above, the two suction holes 6f are formed in the form shown in FIG. 8, but the position, number, shape, etc. of the suction holes 6f can be changed in various ways. is there.
