Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to the polarity or insulation direction of electronic components with lead wires (axial type electronic components) such as diodes, capacitors, fixed film resistors, wire-wound resistors, etc. The present invention relates to a direction sorting device for aligning.

Prior Art For example, the diode D shown in FIG. 6 has a main body d1.
Although lead wires d2 are provided on both sides of the lead wires, it is necessary to align them so that their polar directions are aligned before performing characteristic measurements. In addition, a fixed film resistor R shown in FIG. 7A
is provided with lead wires r2 on both sides of main body r1, and insulating part r3 is applied to the base of one lead wire r2, forming as shown in FIG. 7B (substrate press-fit)
and taping as shown in FIG. 7C. In addition, before color coating, stamping, etc., it is necessary to align the insulation directions so that they are aligned. Insulating parts may also be provided on the lead wires of diodes, capacitors, and wire-wound resistors, but in this case as well, it is necessary to align the polarity directions.

Conventionally, the following three methods can be cited as typical examples of devices for aligning the directions of electronic components with lead wires.

(1) An electronic component with a lead wire is transported by a chain with an attachment, and the polarity of the electronic component with a lead wire is measured during the transportation. After the measurement, if the polarity of the lead wired electronic component is in the opposite direction, a jig is raised from below the chain, and the lead wired electronic component is removed above the attachment using this jig. After detachment, the jig and electronic component with lead wire are rotated 180 degrees, the jig and electronic component with lead wire are lowered, and the electronic component with lead wire is lowered onto the chain with attachment.

(2) Feed the electronic component with lead wires to the rotating measuring wheel using the chute, measure the polarity of the electronic component with lead wires while the measuring wheel is rotating, and then remove the electronic component with lead wires after measurement. Drop it sideways from the measuring wheel. At this time,
Depending on the measurement signal, bring the lead wires on either side into contact with the claws and drop them vertically to align the polarities. This dropped electronic component with lead wire is supplied to the rotating supply wheel by a chute,
This method supplies the chain to a chain with an attachment and transports it.

(3) A groove is formed on the outer periphery of the rotary disk, and a clamp member is attached to the outer periphery of the rotary disk to rotatably hold the electronic component body within the groove, and the electronic component with lead wires supplied to the rotary disk is clamped as described above. It is held by a member and the polarity of the electronic component with lead wires is measured while the rotary disk is rotating. After measurement, if the polarity of the electronic component with lead wires is in the opposite direction, push up the lead wires with the correction claw, guide the pushed up lead wires with the reversing plate, and use the grooves above to remove the electronic component with lead wires. After rotating 180 degrees and aligning, the clamp member is released and the electronic components with lead wires are transferred to the supply rotary disk.

Problems to be Solved by the Invention However, in the first method, the jig needs to be raised, reversed, and lowered, and there are many steps, so the direction alignment work for electronic components with lead wires is approximately 120 pieces per minute. ,
Poor work efficiency. Moreover, if the lead wire is bent, there is a risk that it may enter an adjacent attachment when descending, which tends to cause transportation troubles. In addition, in the second method described above, the direction alignment work of electronic components with lead wires is approximately 300 pieces per minute, and although the efficiency of the alignment work itself can be improved, it is difficult to keep the electronic components with lead wires in contact with the claws. Since it is dropped onto the chute while being inverted, it becomes unstable and tends to cause inversion mistakes. Moreover, since it is a double chute, if the lead wire is bent, it will easily become clogged, resulting in poor work efficiency. In addition, in the third method described above, the direction alignment work of electronic components with lead wires is approximately 300 pieces per minute, and although work efficiency can be improved, since the lead wires are reversed by applying a direct load with the straightening claw, There is a risk of bending the lead wires, so it cannot be carried out particularly when aligning electronic components using lead wires made of soft materials.

Therefore, the present invention can improve the work efficiency of directional alignment of electronic components with lead wires, can prevent reversal errors, and can prevent lead wires from bending, allowing lead wires made of various materials to be used. It is an object of the present invention to provide a direction alignment device for electronic components with lead wires, which can be carried out in the direction alignment work of electronic components, and furthermore, does not require monitoring and can save labor.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to provide a structure that is rotatably provided, and grooves for engaging lead wires of electronic components are arranged at approximately equal intervals on the outer periphery. A measuring wheel provided in large numbers, a device for rotating the measuring wheel, and a detecting device for detecting a direction by contacting a lead wire of an electronic component with a lead wire engaged in an engagement groove of the measuring wheel. , At a position downstream from this detection device in the rotational direction of the measuring wheel, the electronic components with lead wires in the forward and reverse directions are swung toward the entrance and exit side and the bottom side of the engagement groove of the measuring wheel, respectively, according to the command from the detection device. A sorting device, which guides the electronic components with lead wires sorted by the sorting device in a sorted state as the measuring wheel rotates, and separates the electronic components with lead wires in the forward and reverse directions into different directions of the measuring wheel. A guide member for ejecting electronic components with lead wires at a certain position, a receiving plate in which a hole for ejecting electronic components with lead wires is formed, and electronic components with lead wires that are rotatably supported on the receiving plate and falling in the opposite direction are accommodated. A direction changing wheel in which a plurality of direction changing holes are radially formed for conversion, and the direction changing wheel is rotated to eject the electronic components with lead wires. and a direction changing device consisting of a drive device that sequentially aligns the direction with the holes.

Effect The effects of the above technical means are as follows.

As the measurement wheel rotates, the electronic component with the lead wire engaged in the engagement groove detects the direction of the lead wire by a detection device, and the direction of the lead wire is determined by the operation of the sorting device based on the command from the detection device. Distribute the electronic components with lead wires in the direction to the entrance/exit side of the engagement groove and the groove bottom side. As the measuring wheel rotates,
The electronic components with lead wires are transferred and discharged in the sorted state as described above under the guidance of the guide member. The electronic component with the lead wire in the opposite direction falls into the direction change hole of the direction change wheel that is being rotated, and its direction is changed in the forward direction by the rotation of the direction change wheel. The electronic component with lead wires after the direction change can be discharged from the discharge hole by aligning the direction change hole with the discharge hole of the receiving plate. Therefore, the electronic components with lead wires can be continuously aligned and transported to a desired process by a transport device or the like without bending the lead wires.

A sprocket 72 is mounted on the rotating shaft 70, and the sprocket 72 is connected to a drive source via a chain (not shown). Guide members 73 are mounted on the horizontal plate 67 to prevent the lead wire d2 of the diode D, which is located on both sides of the conveyance chain 69 and is engaged with the conveyance chain 69, from shifting laterally.

Next, the operation of the above embodiment will be explained. The diode D is fed from the parts feeder into the hopper 25 shown in FIG. The diodes D in the hopper 25 are sequentially ejected one by one due to the vibration caused by the vibration source 26, and fall down the passage 27 of the lightning bolt type chute 24. The main body d1 of the dropped diode D is sequentially engaged with the engagement groove 23 of the rotating supply wheel 22. The diode D in the engagement groove 24 is guided by the guide member 28 and moved downward as the supply wheel 22 rotates. In this way supply wheel 2
The lead wires d2 of the diodes D transferred downwardly are sequentially engaged with the engagement grooves 8 of the rotating measuring wheel 5. At this time, the lead wire d2 is supported by the receiving member 10 on the entrance/exit side of the engagement groove 8. This diode D is transferred on the receiving member 10 as the measuring wheel 5 rotates, and is connected to the lead wire d2.
contacts the detection plate 30 of the detection device 11, and its polar direction is detected. If the polarity is in the opposite direction, the distribution lever 42 is activated by a command from the detector 36.
The distribution portion 45 collapses and bridges the outer circumferential surface of the receiving member 10 and the outer circumferential surface of the guide member 13. As a result, the diode D has its lead wire d2 connected to the distribution section 45.
The outer periphery of the guide member 13 is engaged with the entrance/exit side of the engagement groove 8 and transferred. At this time, the main body d1 of the diode D is guided by the guide member 14 to prevent it from coming off the engagement groove 8. When the diode D in the opposite direction leaves the guide member 14,
The direction changing wheel 5 detaches from the engagement groove 8 of the measuring wheel 5, falls, rotates, and stops.
They are sequentially accommodated in the two direction changing holes 56 and supported on the pins 3. The diode D housed in the direction changing hole 56 is pushed by the inner wall of the direction changing hole 56 as the direction changing wheel 52 rotates as described above, and is transferred on the pin 74 while changing direction. During this time, the subsequent diode D is stored in the subsequent direction change hole 56, but the main body d1 of this subsequent diode D is stacked on the main body d1 of the diode D stored in the previous direction change hole 56. It will be done. Direction changing wheel 5
The rotation of step 2 causes diode D to move in the same direction as when it was dropped.
When the direction is changed to a direction crossing 162 degrees, the lead wire d2 separates from the pin 74 and falls onto the receiving plate 51. When the direction change hole 56 of the direction change wheel 52 is further rotated by about 18 degrees, that is, about 180 degrees from the initial state, the direction change hole 56 of the direction change wheel 52 coincides with the discharge hole 55 of the receiving plate 51, so that the lead wire d2 is aligned horizontally with the pin 74. The diode D transferred through the lower side of the section is discharged from the direction change hole 56 through the discharge hole 55. The discharged diode D is conveyed to a desired process by having its lead wire d2 engaged with an attachment of a traveling conveyance chain 69.

Also, if the polarity of diode D is positive,
The solenoid 37 is energized by the command from the detector 36, and as shown in FIG. It comes into contact with the distribution part 45 and moves to the bottom side of the engagement groove 8,
In this state, it is transferred along the inner peripheral surface of the guide member 13. The main body d1 of the diode D that has left the guide member 13 is guided by the guide member 15 and transported. When the diode D leaves the guide member 15,
It is discharged from the measurement wheel 5, and the lead wire d2 is engaged with the engagement groove 63 of the rotating first discharge wheel 61. As the first discharge wheel 61 rotates, the diode D is guided by the guide member 65 and transferred downward. When the transferred diode D leaves the guide member 65, it is engaged with the engagement groove 64 of the rotating second discharge wheel 62. As the second discharge wheel 62 rotates, the diode D is guided by the guide member 66 and transferred downward, and when it leaves the guide member 66, it falls downward, and the lead wire d2 is transported downward. It is engaged with the attachment of the chain 69 and transported to a desired process. Therefore, the conveyor chain 6
At 9, the polarity directions of the lead wires d2 of all the diodes D are aligned and transported.

According to the above embodiment, the direction alignment work of the diodes D can be performed at a rate of about 350 diodes per minute.

In the above embodiment, the lightning bolt type chute 24 is used as the supply device 9, but it may also be supplied from a feeder (not shown) to the supply wheel 22 shown in FIG. 1 via a supply wheel (not shown). good. Also, the measuring wheel 5 and the supply wheel 2
2. Direction changing wheel 52, discharge wheel 6
1 and 62 may be rotated intermittently. In addition, the present invention can be modified in various ways without departing from its basic technical concept.

Effects of the Invention As is clear from the above description, according to the present invention, as the measurement wheel rotates, the direction of the lead wire of the lead wire-equipped electronic component that is engaged with the engagement groove is detected by the detection device. By operating the sorting device based on the commands from the detection device, electronic components with lead wires in the reverse direction and in the forward direction are sorted into the entrance/exit side of the engagement groove and the groove bottom side. As the measurement wheel rotates, the electronic components with lead wires are transferred and discharged in the sorted state as described above by the guidance of the guide member. An electronic component with a lead wire in the opposite direction is dropped into the direction change hole of the direction change wheel which is being rotated, and the direction is changed in the forward direction by rotation of the direction change wheel. Electronic components with lead wires after direction change can be discharged from the discharge hole by aligning the direction change hole with the discharge hole of the receiving plate. Therefore, the direction of the electronic components with lead wires is aligned. It can be transported to a desired process using a transport device or the like. In this manner, the direction detection and sorting operations are performed while the electronic components with lead wires are being transferred by the rotation of the measuring wheel, so that the efficiency of the directional alignment operation can be improved. In addition, since the direction is changed to the positive direction by rotating the direction change wheel, it is possible to prevent reversal errors and also to prevent bending of the lead wire, so it is possible to use various types of leads without being affected by the material of the lead wire. This method can be used to align the directions of electronic components with wires, and can also prevent transportation troubles. Therefore, monitoring becomes unnecessary and labor saving can be achieved.
