DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic electronic component supply device configured to supply an electronic component having cap-shaped electrodes attached to at least both ends to a supplied object, and particularly to It is an object of the present invention to provide a novel automatic feeding device for electronic parts which can be reliably fed to the body and which can simplify the structure for this purpose. This will become clear from the detailed description of an example of an automatic supply device for electronic components.

First, to describe an electronic component that can be applied to the present invention, an example thereof is, for example, a carbon film resistive element, which is generally designated by the reference numeral 1 as shown in FIG.
A pair of cap-shaped electrodes 3 are provided at both ends of a resistance element body 2, which is formed by attaching a carbon film to the surface of a cylindrical or cylindrical insulating substrate.
and 3' are attached to the pair of cap-shaped electrodes 3 and 3.
A pair of leads 4 and 4' made of a conductive material are attached to the resistive element body 2 and the cap-shaped electrodes 3 and 3, respectively, which can be extended outward by a predetermined length in the left and right directions. ' is covered with an insulating film.

In this case, each of the pair of cap-shaped electrodes 3 and 3' is made of a magnetic material, for example, iron.

The above is an example of an electronic component that can be applied to the present invention. Next, an automatic electronic component supply device according to the present invention, which is adapted to supply such an electronic component to a supplied object, will be described with reference to FIG. In FIG. 2, reference numeral 11 indicates a main body of the supply device that accommodates a large number of the above-mentioned resistive elements 1, and as is clear with reference to FIG. Each of the component supply tools 12 has a spherical diaphragm 13, for example, whose center part is bulged upward, at the bottom thereof, as is clear with reference to FIG. A guide groove 14 is formed on the inner circumferential surface of the diaphragm 13 so as to spirally extend upward from a position facing the outer circumferential edge of the diaphragm 13 to the upper end surface of the case body 12.

In this case, the diaphragm 13 is connected to a drive source (not shown), and is rotated by this drive source at a relatively slow speed clockwise at a predetermined angle when viewed from the plane, and then rotated in the opposite clockwise direction. If the above-mentioned resistance element 1 is placed on this diaphragm 13, The resistance element 1 is transferred to the outer circumferential edge of the diaphragm 13 and thus to the inner circumferential surface of the component supply tool 12 in the direction of discontinuation, and is delivered to the guide groove 14.

Therefore, if a large number of resistance elements 1 are stored in this component supply tool 12, the second equal resistance elements 1 are sequentially fed into the guide groove 14, thereby moving upward in this guide groove 14 one after another. It is done like this.

Further, reference numeral 21 denotes a holding means for temporarily holding the resistive element 1 from the supply device main body 11, which is formed, for example, in the shape of a rectangular parallelepiped as a whole and is made of a non-magnetic material, as is clear with reference to FIGS. 3 and 4. For example, it has a case body 22 attached to the guide groove 14 position on the upper surface of the above-mentioned supply device 12, and a resistance element 1 that communicates with the above-mentioned guide groove 14 is connected to the front right side of the case body 22, and its leads 4 and 4' are tied together. A first guide part 23 made of, for example, an arc-shaped guide groove is provided, and the first guide part 23 is formed of, for example, an arc-shaped guide groove, and is guided in a substantially horizontal direction. Lever guide part 23
A case in which a similarly arc-shaped guide groove 24 located slightly below the guide groove 24 and a resistance element 1 connected to the guide groove 24 on the rear side thereof are guided so that the direction in which the leads 4 and 4' are connected is approximately horizontal. A second guide portion 26 consisting of a guide hole 25 that penetrates the case body 22 and extends rearward is disposed, and a permanent magnet 27, for example, is disposed on the upper surface of the case body 22 facing the guide hole 25. A magnetic leg 28 made of a magnetic material, for example, an iron plate is attached to the front end face of the magnet 27.
The lower end of the guide hole 25 is located below the upper end surface of the case body 22.
A semicircular notch 30 corresponding to the guide hole 25 is attached to the extended portion of the guide hole 25 through a split groove 29 that can be extended, and a side surface 31 forming the guide portion 23 of the case body 22 is provided with a semicircular notch 30 corresponding to the guide hole 25. It has a configuration in which the rear portion thereof is curved and extended in an arc shape.

In this case, the length of the guide groove 24 is equal to the length between the free ends of the leads 4 and 4' of the resistance element 1.

are chosen almost equally. Further, a bypass hole 32 is provided to communicate between the rear side of the magnetic leg 28 of the guide hole 25 and the rear side of the side surface 31 forming the guide portion 23.

As described above, when the resistance element 1 is guided by the guide groove 14 of the supply device main body 11 and brought to the position of the guide part 23, the first resistance element 1 is placed at the free end of the lead 4 or 4'. is guided by the curved portion of the side surface 31 and moved into the guide groove 24, and when the resistance element 1 is brought into the guide groove 24, the cap-shaped electrodes 3 and 3' are made of magnetic material. Therefore, one side of these magnetic legs 28 is attracted by the magnetic legs 28, and thus the resistive element 1 is held in that position.

While the first resistive element 1 is being held, the free end of the lead 4 or 4' of the succeeding resistive element 1 is similarly guided by the side surface 31 into the guide groove 24. However, since the free end of the lead 4 or 4' is held in the guide groove 24, the first resistance element 1 is held in the guide groove 24, so this is prevented by contacting the element body 2, and this resistance The resistance elements 1 following element 1 fall onto the diaphragm 13 one after another because the advance of the previous resistance element 1 is blocked as described above.

Further, reference numeral 41 indicates a supply means for supplying the resistive element 1 held by the above-mentioned holding means 21 to the supplied object 81, which will be described later. For example, four inverted truncated cone-shaped through holes 44a to 44d are bored in the lower surface plate 43, and through holes are formed in the upper surface plate 45 at positions facing the through holes 44a to 44d, respectively. 46a to 46d are connected to pipes 48a to 48d in such a manner that a through hole 47 is bored in the left side thereof, and the through holes 44a to 44d are reached through the through holes 46a to 46d, respectively.
The free ends of the secondary pipes 48a to 48d are connected to the guide hole 25 of the holding means 21 mentioned above, and a pipe 49 communicating therewith is connected in the through hole 47.
The free end of the pipe is connected to a vacuum source 51 via a switching valve 50, and the pipe 52a to 52d, which has a translucent property, is connected to a holding means 61, which will be described later, in communication with the through hole 44a to 44d. The free ends are connected.

Further, 61 indicates a holding means for temporarily holding the resistive element 1 from the supply device main body 11 mentioned above at a position below the supply means 41 mentioned above, for example, the upper plate part 62 and the lower plate part 63. Side plate part 64 that can be extended between the right edge of the lower plate part 63
and a fixed guide plate 65 formed into a U-shape when viewed in cross section;
A movable guide plate 66 is provided between the upper plate part 62 and the lower plate part 63 of the fixed guide plate 65 so as to be slidable in the left and right direction, for example.

In this case, the fixed guide plate 65 has an upper plate portion 62 and a lower plate portion 6.
The through holes 44a of the fixing plate 42 of the supply means 41 mentioned above in 3.
Through holes 67a to 67d and 6 are provided at positions opposite to 44d, respectively.
8a to 68d are bored, respectively.

In this case, the through holes 67b to 67d and 68b to 68d are guided vertically in the direction in which the leads 4 and 4' of the resistor element 1 are connected, so that the diameter thereof when viewed in cross section is approximately the diameter φ of the resistor element 1.

It is made almost equal.

Also, the movable guide plate 66 is connected to the through holes 67a to 67 of the fixed guide plate 65.
Through holes 69a to 69d similar to d and 68a to 68d are bored, and this movable guide plate 66 is connected to a suitable connecting mechanism 7.
It is connected to the drive source 71 through 0 and is slidable left and right, however, at the right sliding position, through holes 69a to
69d are the through holes 67a to 67d and 68 of the fixed guide plate 65.
The holes 69a to 69d are positioned on the plate surface of the fixed guide plate 65 on the right side from the positions a to 68d, and when the plate is slid to the left, the through holes 69a to 69d correspond to the through holes 67a to 67a of the fixed guide plate 65, respectively.
67a and 68a to 68d, and the pipes 52a to 52d from the supply means 41 are connected to the through holes 67a to 67d of the fixed guide plate 65,
Further, pipes 72a to 72d are connected to the through holes 68a to 68d, respectively, in communication with a supplied body 81, which will be described later.

Note that 75 is a stopper engager for regulating the left sliding position of the movable guide plate 58.

Also, the pipes 52a to 52 on the upper surface of the fixed guide plate 65
Detecting means 74a to 74d consisting of, for example, a light emitting element 73 and a light receiving element 73' are disposed at positions facing each other with d in between, and these detecting means 74a to 74d detect the pipe 52a.

A detection signal indicating whether or not the resistive element 1 is present in the detection means 74a to 74d is obtained, and the drive source 71 described above is controlled based on the detection signal from the detection means 74a to 74d. is being done.

Further, reference numeral 81 indicates an object to which the above-mentioned resistance element 1 is supplied, which is arranged below the holding means 61, and the pipes 72a to 72d from the above-mentioned holding means 61 are connected to which the resistance element 1 is supplied. It is designed to be supplied.

The above is an example of the configuration of the automatic electronic component supplying device according to the present invention.To further describe the operation, as described above, the first negative resistance element 1 from the supplying device main body 11 is connected to the guide portion 26 of the holding means 21. The next negative resistance element 1 is held in the guiding part 23, and the movable plate 66 of the holding means 61 is in a position where it can slide to the right, so that the through holes 67a to 67d of the fixed plate 64 is blocked by the upper surface of the movable plate 66, and if the switching valve 50 of the supply means 41 is switched to establish communication between the vacuum source 51 and the fixed plate 42, the air inside the fixed plate 42 will be transferred to the vacuum source 51. In this case, the through holes 67a to 67 of the fixed guide plate 65 of the holding means 61
d is closed by the movable plate 66, so the pipe 48a
The air in ~48d is suctioned, and the resistance element 1 held by the guide portion 26 of the holding means 21 is suctioned, passing through the pipes 48a~48d, and further through the pipes 52b~52d to the movable plate 66 of the holding means 61. You can receive it.

In this case, when the resistance element 1 held by the guide part 26 of the holding means 21 is suctioned by the vacuum source 51, the resistance element 1 held by the guide part 23 is also suctioned at the same time. However, in this case, the resistance element 1 is
3 and this guide part 26, a side passage hole 32 is formed between the side passage hole 32 and the vacuum source 51 through this side passage hole 32.
The resistive elements 1 are arranged so as not to move, so that only one resistive element 1 is attached to the pipes 48a to 48d from the holding means 21.
This is what is sent to.

In addition, the resistance element 1 that passes through the pipes 52a to 52d and is received on the upper surface of the movable plate 66 cannot pass through the pipes 52a to 52d because the holding means 61 side of the pipes 52b to 52d is closed by the movable plate 66. When the resistance element 1 passes, the air between it and the movable plate 66 is compressed by the resistance element 1, and the falling speed is reduced by the air resistance, so that the second resistance element 1 is movable. If the lead 4 or 4' is received by the plate 66, it is inevitable that the lead 4 or 4' will be deformed or damaged.

If the resistance element 1 is received on the movable plate 66 as described above, the detection means γ4a.

Detection signals are obtained from each of 74b, 74c, and 74d, so that the drive source 71 can drive them.

Therefore, when such a state is obtained, the rear drive source 71 is driven to move the movable plate 66 to the left through the through hole 69 through the coupling mechanism 71.
When a to 69d are slid to communicate with the through holes 67a to 67d and 68a to 68d of the fixed guide plate 65, the resistance elements 1 received on the upper surface of the movable plate 66 simultaneously Through holes 69a, 69b, 69c and 69d
, through holes 68a and 68b of the guide plate 65.

68c and 68d, and pipes 72ay72b.

It is to be guided to the object to be supplied 81 through 72c and 72d, respectively.

As described above, according to the present invention, the resistive elements 1 sequentially supplied from the component supply tool 12 of the supplying device main body 11 are held by the second guide portion 26 of the holding means 21, and the resistive elements 1 are The other negative resistance element 1 is made to stand by at the first guide part 23, and the resistance element 1 is held by the second guide part 26 of the holding means 21 by the operation of the supply means 41.
Since the resistance element 1 is supplied to the object to be supplied 81, the supply of the resistance element 1 to the object to be supplied 81 is ensured. Since the resistance element 1 to be put on standby is held through the bypass hole 32 communicating between the first and second guide parts 23 and 26 when the supply means 41 is activated, the second resistance element 1 of the holding means 21 is Since only the resistive elements 1 held by the guide portion 26 are supplied, this can be done reliably without malfunction, and the main body of the supplying device is configured to supply the resistive elements 1 in sequence. 11, a holding means 21, and a supply means 41, and is of a simple, long structure.

In the above description, the electronic component is the resistance element 1 having the leads 4 and 4'.
It will be obvious that the present invention can be applied to resistive elements that do not have a resistive element or to other electronic components as long as they have electrodes at both ends.

In addition, although the case where one spiral guide groove 14 is provided on the inner circumferential surface of the case body 12 of the supply device main body 11 has been described above, it is also possible to provide a plurality of guide grooves similar to the guide grooves 14. In this way, a plurality of resistive elements 1 can be supplied simultaneously from one supplying device main body 11.

Further, in the above description, the case was described in which the component supply tool 12 of the supply device main body 11 has a diaphragm 13, but this is sufficient as long as the electronic components are supplied sequentially. .

Further, in the above description, the case where the holding means 21 is directly attached to the supplying device body 11 has been described, but the holding means 21 is not limited to this, and it can also be arranged between the supplying device body 11 and the object to be supplied 81. Various other modifications may be made.
