Description

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

Conventional technology For example, the diode D shown in Fig. 9 has a main body b1
Although lead wires d2 are provided on both sides of the lead wires, they must be aligned so that their polar directions are aligned before performing characteristic measurements. Furthermore, if the fixed resistor R shown in FIG. 10A is equipped with a lead wire r2 of a main body r1, and an insulating part r3 is applied to the base of one lead wire r2, the forming (board press-fit) shown in FIG. 10B is performed. Then, taping as shown in FIG. 10C is performed, and before performing 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 reversed, 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 transfer the electronic component with lead wires after measurement to the measuring wheel. Make it fall more sideways. At this time, the lead wires on either side are brought into contact with the claws according to the measurement signal, and the lead wires are dropped vertically to align the polarities. A system in which the dropped electronic components with lead wires are supplied to a rotating supply wheel using a chute, and from there, they are supplied to a chain with an attachment and transported.

(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 reversed, push up the lead wire with the correction claw, guide the pushed up lead wire with the reversing plate, and use the above groove 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 rotating board for supply.

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.
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 the efficiency of the alignment work itself can be improved. Since it is dropped onto the chute while being inverted, it becomes unstable and tends to cause inversion errors. Moreover, since it is a double chute, if the lead wire is bent, it is likely to 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, which improves work efficiency. There is a risk of bending the lead wire, so it cannot be carried out especially when aligning electronic components using lead wires made of soft material.

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 can be used to align the direction of electronic components, thus eliminating the need for monitoring and saving labor.Furthermore, the opening/closing position of the chuck member remains unchanged on the outer circumference of the rotating body, allowing parts with lead wires to be easily aligned. The direction of electronic components with lead wires allows for easy assembly of each component, such as supply, detection, and discharge, and also simplifies the configuration by placing the reversing device of the chucking device in one place. The present invention seeks to provide an alignment device.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems includes: a rotating body; support cylinders rotatably supported at a plurality of locations on the outer periphery of the rotating body at approximately equal intervals;
A chuck member that is openable and closable in a fixed position with respect to the support tube and capable of gripping an electronic component with a lead wire; a spring that urges the chuck member to close; and a chuck member that moves in the axial direction inside the support tube. a movable member that opens the chuck member against the elasticity of the spring; a chucking device having a plurality of protrusions provided on the outer periphery of the support tube; and a movable member that opens the chuck member against the elasticity of the spring; positioning means for holding the movable member in a rotational position every 180 degrees, an opening curved surface provided on the center side of the rotating body for advancing the movable member to the chuck member open position; a fixed cam having a gripping curved surface for retracting to a position; a detection device that detects the direction by contacting the lead wire of the electronic component with a lead wire gripped by the chucking device; and a position downstream of the rotating body from the detection device. a plurality of operating protrusions provided so as to be able to advance to a position where they engage with the plurality of protrusions or retreat to a position where the protrusions pass; and a drive for advancing or retracting the operating protrusions in response to commands from the detection device; The chucking device is rotated 180 degrees against the spring force of the positioning means by engagement with the protrusion of the chucking device that grips the electronic component with the lead wire when the operation protrusion moves forward, and the lead wire is rotated by 180 degrees against the spring force of the positioning device. It is equipped with a reversing device for reversing it so that it faces in the opposite direction.

Effects The effects of the above technical means are as follows.
That is, as the rotating body rotates, when the movable member moves forward by the opening curved surface of the fixed cam provided on the center side of the rotating body, the chuck member opens against the elasticity of the spring, and the movable member grips the fixed cam. When the chuck member is retracted by the curved surface, the chuck member closes due to the elasticity of the spring. Then, the electronic component with the lead wire is supplied to the chuck member in the open state, and when the movable member retreats by the gripping curved surface of the fixed cam as the rotating body rotates as described above, the chuck member closes and the electronic component with the lead wire is supplied to the chuck member in the open state. Grip electronic components. As the rotating body rotates, the gripped electronic component with lead wires has a detection device that detects the direction of the lead wires, and if the direction is reversed, the operating protrusion of the reversing device moves forward according to a command from the detection device. Then, the protrusion of the chucking device that grips the electronic component with the lead wire is engaged with this operation protrusion, and the chucking device is rotated 180 degrees against the spring force of the positioning means, and the lead wire is reversed so that it is oriented in the opposite direction. The electronic components with lead wires aligned in this manner are ejected when the movable member is advanced by the opening curved surface of the fixed cam and the chuck member is released.

In addition, the supporting tube of the chucking device is held at rotational positions of 180 degrees by the spring force of the positioning means, and the operating protrusion is engaged with the protrusion of the chucking device to rotate the chucking device 180 degrees.
Since it is designed to be reversed every time, the reversing device having the operating protrusion only needs to be provided at one location.

Then, the diode D in the parts feeder is fed into the hopper 43 through the chute 45, and the diode D in the hopper 43 passes through the passage 46 of the lightning-shaped chute 42.
The body d1 is sequentially received by the receiving groove 41 of the rotating supply wheel 40. A support member 47 for preventing the diode D from coming off from the receiving groove 41 is provided on the outside of the supply wheel 40 that reaches the discharge position on the lower side of the supply position of the diode D with respect to the supply wheel 40 of the lightning bolt type chute 42. ing.

An insulating material 49 is used for detection at least at the detection position of 8.

To explain the detection device 34, as shown in FIGS. 1 and 2, with respect to the lead wires d2 on both sides of the diode D held by the tracking device 5,

An operation plate 58 is slidably supported on these guide shafts 57, and a shaft 59 of a solenoid 56 is connected to the operation plate 58. On the front surface of the operation plate 58, a plurality of (four in the illustrated example) operation protrusions 60 that sequentially engage with the protrusions 24 of the chucking device 5 are arranged in parallel at equal intervals along the moving direction of the chucking device 5. (See Figure 5). The solenoid 56 is connected to the detector 54, and the solenoid 56 is energized by a command from the detector 54, and the shaft 59 and the operation plate 5 are energized.
8 is moved forward, and the operating projection 60 is positioned so as to mesh with the projection 24 of the chucking device 5, as shown in FIG. Accordingly, as the chucking device 5 moves as the rotating body 4 rotates, its protrusions 24 successively engage with the operating protrusions 60 of the operating plate 58 and are reversed approximately 180 degrees. Thereafter, when the solenoid 56 disappears, the shaft 59, the operation plate 58, and the operation protrusion 60 retreat to the position where the protrusion 24 passes.

The redetection device 36 shown in FIG.
This is provided to compensate for detection errors caused by adhesion of dust etc. in the detection device 34, and is configured similarly to the detection device 34.
Although the detailed explanation is omitted, the difference from the detector 34 is that the detector 5

There are multiple locations on the outer circumference of the unloading wheel 63 (8 in the illustrated example).
Receiving grooves 64 are formed at equal intervals. Thus, the body d1 of the diode D released from the chucking device 5 as the carrying-out wheel 63 rotates can be received in the receiving groove 64 one after another. On the outside of the carry-out wheel 63 that reaches the carry-out position below the receiving position of the carry-out wheel 63, there is a support member 6 that guides the diode D so that it does not come off from the receiving groove 64.
5 is provided. A diode D discharged from the carry-out wheel 63 is located below the carry-out wheel 63.
A pair of conveyance chains 66 with attachments are provided for receiving the lead wire d2 and conveying it to the next process.

A lead wire is connected to prevent the diode D from detaching from the chucking device 5 in the range from the position of the re-detection device 36 to the receiving position by the unloading wheel 63.
A support member 67 that supports d2 is provided.

As shown in FIG. 2, timing wheels 68 and 69 are mounted on the rotating shafts 3 and 62, and a timing wheel (not shown) is also mounted on the rotating shaft 39 (see FIG. 2). A timing belt 7 is attached to a timing wheel (not shown) mounted on the motor output shaft.
0 is applied, and the rotating body 4, the supply wheel 40, and the delivery wheel 63 can each rotate in the direction of the arrow shown in FIG. 1 by driving the motor.

Next, the operation of the above embodiment will be explained. First, the motor is driven as described above, and the rotating body 4,
The supply wheel 40 and the discharge wheel 63 are rotated in the direction of the arrow in FIG. Along with this, the diode D is connected to the chute 4 shown in Fig. 3 from the parts feeder.
5 and then put into the hopper 43. Hopper 43
The diode D inside is connected to the hopper 4 by the vibration source 44.
3, the pieces are sequentially ejected one by one and fall down the passage 46 of the lightning-shaped chute 42. The fallen diode D is delivered to the receiving groove 41 of the supply wheel 40 whose main body d1 is rotating. The diode D in the receiving groove 41 is supported by the support member 47 and transferred downward as the supply wheel 40 rotates. On the other hand, when the rotor 23 of the chucking device 5 rides on the opening curved surface 31a on the upper part of the fixed cam 30 as described above with the rotation of the rotor 4, movable members such as the rotor 23, the opening/closing shaft 20, the pressing body 21, etc. 19 advances radially outwardly, opening the chuck member 11 against the elasticity of the spring 18 (see dashed lines in FIG. 4A).
The diode D transferred below the supply wheel 40 as described above is supplied onto the support member 48 inside the chuck member 11 whose body d1 is open. As the chucking device 5 moves, this diode D is pushed by one of the chuck members 11 and rolls on the support member 48, and the rotor 23 separates from the opening curved surface 31 of the fixed cam 30 and moves onto the gripping curved surface 32. Once reached, the chuck member 11 is moved by the spring 18.
The operation part 14 is urged inward, the movable members 19 such as the pressing body 21, the opening/closing shaft 20, and the rotor 23 are retreated inward in the radial direction, and the chuck member 11 is closed. Grasp the main body d1 of the diode D (see solid line in FIG. 4A).
The diode D moves while being held by the tracking device 5, and the lead wire d2 is connected to the detection device 34.
The polarity direction is detected by contacting the detection plate 50. When the polarity direction is reversed, when the chucking device 5 reaches the position of the reversing device 35,
The solenoid 56 is excited by the command from the detector 54, and the shaft 59 and the operation plate 58 move forward. As a result of this forward movement, the first to fourth protrusions 24 of the chucking device 5 are sequentially engaged with the first to fourth operating protrusions 60 of the operating plate 58, as shown in FIG. approximately 180 against
rotated by degrees. At this time, even if the chucking device 5 has not completely rotated 180 degrees, the flat portion 29 of the support tube 8 is rotated against the control plate 2 due to the elasticity of the compression spring 28.
7, so it is controlled to be completely inverted 180 degrees. If the polarity direction of the diode D is correct, the solenoid 56 is not excited, the operation plate 58 is retracted, and the chucking device 5 and diode D pass through the reversing device 35 as they are. The polarity direction of the diode D which has passed through the reversing device 35 in this manner is re-detected by the re-detecting device 36. If the redetection device 36 makes a detection error, the drive of the motor is stopped by a command from the detector 54, and the diode D is taken out from the chucking device 5. In most cases, the polarity direction of the diodes D is detected by the detection device 34, and the polarity direction is aligned in the correct direction by the reversing device 35, so that these diodes D pass through the redetection device 36 as they are. After passing, when the rotor 23 of the chucking device 5 rides on the lower opening curved surface 31b of the fixed cam 30, the movable members 19 such as the rotor 23, the opening/closing shaft 20, and the pressing body 21 move outward in the radial direction in the same manner as described above. The chuck member 11 is released against the elasticity of the spring 18. As a result, the diode D is released and discharged into the receiving groove 64 of the carry-out wheel 63. The diode D received in the receiving groove 64 is supported by the support member 65 as the carry-out wheel 63 rotates, is transferred downward, falls onto the conveyance chain 66, and is attached to the lead wire.
d2 is engaged with the attachment and transported to the next process.

According to the above embodiment, the direction alignment of the diodes D can be performed at a rate of approximately 300 diodes per minute.

In the above embodiment, the chucking device 5 grips the main body d1 of the diode D, but may grip the base of the lead wire d2.

FIG. 7 is a schematic explanatory diagram showing a second embodiment of the present invention. In this embodiment, the diode D is supplied from the magnetic feeder 71 via the supply wheel 40 to the chucking device 5 from a side position, and the diode D after polarity alignment is directly supplied to the chucking device 5 through the supply wheel 40.
It is designed to be transported by dropping it on
The other configurations are the same as those of the first embodiment.

FIG. 8 is a schematic explanatory diagram showing a third embodiment of the present invention. In this embodiment, the diode D is supplied from a lower position to the chucking device 5 by the conveyance chain 72, and the diode D after polarity alignment is dropped into the conveyance chain 66 for conveyance. The configuration is the same as that of the first embodiment.

Effects of the Invention As is clear from the above description, according to the present invention, a chuck member capable of gripping electronic components with lead wires is provided at approximately equal intervals at a plurality of locations on the outer circumference of a rotating body, and a movable member that opens and closes this chuck member. rotatably supports a chucking device having a chuck, the movable member is advanced to the chuck member open position by the opening curved surface of the fixed cam, and the movable member is retreated to the chuck member closed position by the gripping curved surface of the fixed cam. Then, a detection device detects the direction of the lead wire of the electronic component with a lead wire held by the above-mentioned chucking device, and a reversing means reverses the lead wire of the chucking device that grips the electronic component with a lead wire based on a command from the detection device. I'm trying to flip it so that it faces the same direction. Since the detection and reversal operations are performed while the electronic components with lead wires are being transferred by the rotation of the rotating body, the efficiency of the directional alignment operation can be improved. Furthermore, since the chucking device is reversed, reversal errors can be prevented. Moreover, since it is possible to prevent the lead wire from bending, it is possible to carry out the work of aligning the direction of various electronic components with lead wires, regardless of the material of the lead wire, and also to prevent transportation troubles. . Therefore, there is no need for monitoring,
Labor saving can be achieved.

Furthermore, since the fixed cam for opening the chuck member of the chucking device is provided on the center side of the rotating body, the opening/closing position of the chuck member can be kept unchanged on the outer circumference of the rotating body, and therefore the lead It is possible to easily assemble each member, such as supplying, detecting, and discharging electronic components with wires. In addition, the support tube of the chucking device is held at rotational positions of 180 degrees against the spring force of the positioning means, and the chucking device is reversed every 180 degrees by engaging the operating protrusion with the protrusion of the chucking device. Therefore, the reversing device having the operation protrusion only needs to be provided at one location, and the configuration of the reversing device is also simplified.
