DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply device for supplying a bulk electronic component such as a chip component.

[0002]

2. Description of the Related Art This type of conventional apparatus employs a system in which a chip component is transported to a predetermined take-out position by a belt or the like, and the chip component is taken out by a suction nozzle. For example, in order to mount a chip component on a board using this apparatus, the suction nozzle is reciprocated once between the component pick-up position and the component mounting position, and the suction nozzle is moved in each of the component pick-up position and the component mounting position. You need to move it up and down.

[0003]

By the way, electronic components such as chip components to be supplied are usually subjected to a characteristic inspection in a pre-process, and electronic components having defective characteristics are eliminated in the same process in advance. However, since the above-described characteristic inspection requires a dedicated parts inspection line, there is, of course, a problem that the cost for equipment and work increases. Particularly, in recent years, there has been a high demand for cost reduction, and it is necessary to take measures to eliminate the dedicated inspection line as described above.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide inspection of component characteristics and elimination of defective components immediately before component supply without providing a dedicated component inspection line. It is an object of the present invention to provide a component supply device capable of performing the above.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a component passage provided with a plurality of bulk electronic components movable in a state of being aligned in a length direction, and provided at a tip of the component passage. A component discharging means for sequentially discharging the leading electronic component in the component passage from the component discharge port; and a characteristic inspection means for sequentially inspecting the characteristic of the electronic component moving toward the component discharging port in the component path. The inspection means includes a stop mechanism capable of temporarily stopping an electronic component to be inspected at a predetermined position in a component passage, an inspection mechanism capable of performing a characteristic test on the stopped electronic component, and an electronic component having a defective characteristic. And an elimination mechanism that can be eliminated outside the component passage.

[0006] In this component supply device, during the process in which the leading electronic component in the component path is sequentially discharged from the component discharge port, the characteristic of the electronic component moving toward the component discharge port in the component path is checked by the characteristic inspection means. Inspection can be performed sequentially, and when the characteristics of the inspected electronic component are defective, the electronic component can be removed out of the component passage to reliably prevent the electronic component from being erroneously supplied.

As shown in FIG. 17, a solenoid 16a disposed on the lower surface of the device base 11 via a bracket 20, a pin support member 16c connected to a plunger 16b of the solenoid 16a, and a support piece 16e for a stopper 16d. It is composed of The sleeves of the two inspection pins 15 are fixed to the pin support member 16c of the third actuator 16 so as to be parallel to each other with a vertical interval. In the standby state, since the solenoid 16a is not energized, the plunger 16b is retracted to a position where the plunger 16b comes into contact with the stopper 16d by the biasing force of the built-in spring. Although inserted into the moving hole 1a13, it does not protrude into the third linear portion 1a5 of the component passage 1a.

As shown in FIG. 17, the slider 17 has a rectangular cross section slightly smaller than the cross section of the slider moving cavity 1a12, and has a rectangular cross section which can match with the third linear portion 1a5. (Storage hole) 17a. The vertical dimension of the slider 17 (storage hole 17a) matches the length of the chip component P, and one chip component P can be stored in the storage hole 17a in the length direction. The slider 17 is housed in the slider moving cavity 1a12 via the coil spring CS.

Fourth actuator 18 for driving slider
As shown in FIG. 17, a solenoid 18a disposed on the lower surface of the device base 11 via a bracket 20 common to the third actuator 16 and a solenoid so as to be able to contact the left side of the slider 17 in the drawing. A slider pressing member 18c connected to the plunger 18b 18a, a stopper 18d for adjusting the stroke, and a support piece 18e for the stopper are provided. Since the solenoid 18a is not energized in the standby state, the plunger 18
b attempts to move to the left in the figure by the biasing force of the built-in spring, but its movement position is regulated by a regulating member 19c described later. The slider 17 also attempts to move leftward in the figure due to the urging force of the coil spring CS, but its movement position is regulated by the slider pressing member 18c.
Coincides with the third straight line portion 1a5.

As shown in FIG. 17, a fifth actuator 19 for regulating the slide position is a solenoid 19a disposed on the lower surface of the apparatus base 11 via a bracket 20 common to the third and fourth actuators 16 and 18. A regulating member 19c fixed to a plunger 19b of a solenoid 19a so as to be able to contact a left side surface of the slider pressing member 18c in the drawing, and a stroke adjusting stopper 19d;
And a support piece 19e for a stopper. In the standby state, the plunger 19b and the regulating member 19c have been moved to predetermined positions in the right direction in the figure by energizing the solenoid 19a. That is, the slider pressing member 18c
Stops at a position where it comes into contact with the regulating member 19c,
The slider 17 stops at a position where it contacts the slider pressing member 18c.

In this embodiment, an inspection mechanism capable of performing a characteristic inspection on the chip component P is constituted by the inspection pin 15 and the third actuator 16 for driving the inspection pin. In addition, the slider 17, the fourth actuator 18 for driving the slider, and the fifth actuator 19 for regulating the slide position allow the chip component P to be inspected to be temporarily stopped at a predetermined position in the component passage 1a. An elimination mechanism capable of excluding the mechanism and the chip component P having the characteristic failure outside the component passage 1a is configured, and the inspection mechanism, the stop mechanism, and the elimination mechanism constitute a characteristic inspection unit.

The operation of the above embodiment will be described below.

The parts are replenished into the parts storage case 9 by opening the case lid 9f and putting the chip parts P into the parts storage room SC. FIG. 14 shows a small number of chip components P.
Is stored, but actually thousands or tens of thousands of chip components P are stored in the component storage room SC.

In the standby state shown in FIG. 14, the upper end of the parts supply pipe 10a is at the same or slightly lower position as the deepest part of the parts storage chamber SC. The upper end of the movable pipe 10b is located lower than the upper end of the component supply pipe 10a, and an annular space is formed above the movable pipe 10b. In the state shown in the figure, a small number of chip components P have entered the annular space formed above the movable pipe 10b.

In the state shown in FIG. 14, the first actuator 13
When the cam 13b is rotated 180 degrees counterclockwise or clockwise in FIG. 1 by the motor 13a,
The lever 13c rotates a predetermined angle clockwise about the one end 13c1. The engagement piece 13c3 is raised by the rotation of the lever, and the movable pipe 10b is raised against the urging force of the second coil spring 10e as the engagement piece 13c3 is raised (see FIG. 18). One more cam 13b
When rotated by 80 degrees, the lever 13c has its one end 13c1
Around a predetermined angle clockwise. The engagement piece 13c3 is lowered by the rotation of the lever, and the movable pipe 10b is lowered with the lowering of the engagement piece 13c3 (see FIG. 14). That is, by rotating the cam 13b, the movable pipe 10b can be reciprocated vertically.

When the movable pipe 10b rises, as shown in FIG. 18, the chip component P above the movable pipe 10a moves upward, and when the movable pipe 10b is lowered from the raised position, the movable pipe 10b moves downward. The chip component P on the upper side moves downward. Due to the vertical movement of the movable pipe 10b, the chip components P in the component storage room SC are subjected to a stirring action, and as a result, the movable pipe 10b
While being guided by the inclination of the guide surface 10b1, the chip component P on the upper side is taken into the upper end opening of the component supply pipe 10a in the length direction.

The chip component P taken into the component supply pipe 10a moves downward by its own weight in the component supply pipe 10a and is sent into the component passage 1a from the lower end of the component supply pipe 10a. That is, by moving the movable pipe 10b of the pipe mechanism 10 up and down, the chip components P stored in the component storage case 9 are taken into the component supply pipe 10a one by one in the length direction, and the chip The part path 1 through the part supply pipe 10a
a.

The parts passage 1 through the parts supply pipe 10a
The chip component P sent into the “a” has a tapered portion 1a1.
1, a first straight portion 1a1, a first curved portion 1a2, a second straight portion 1a3, a second curved portion 1a4, and a third straight portion 1a
5 to move in order.

Since the thickness dimension of the tapered portion 1a11 is set slightly larger than the maximum value of the diagonal dimension Dp of the chip component P, the chip component P after insertion is shown in FIG.
, That is, the four side surfaces of the chip component P may enter in a posture that is not parallel to the four inner surfaces of the tapered portion 1a11. However, the tapered portion 1a1
Since the thickness dimension of the chip component P gradually decreases downward, the position of the chip component P is corrected by coming into contact with two tapered inner surfaces of the tapered portion 1a11, particularly in the thickness direction, and the first linear portion 1a1 is corrected. Figure 2
1 (B), that is, the four side surfaces of the chip component P face the four inner surfaces of the first linear portion 1a1, respectively.

Further, even when the attitude of the chip component P from the tapered portion 1a11 is disturbed as shown in FIG. 21A when the chip component P passes through the first linear portion 1a1, the chip component P remains in the first position. When passing through the curved portion 1a2, the posture is corrected by contacting the two inner surfaces of the first curved portion 1a2, particularly in the thickness direction, and the proper posture as shown in FIG. 21B is obtained.

Furthermore, even when the attitude of the chip component P from the first curved portion 1a2 passes through the second straight portion 1a3 and the posture of the chip component P is disturbed as shown in FIG. When passing through the second curved portion 1a4, the posture is corrected by contacting the two inner surfaces, especially in the thickness direction, of the second curved portion 1a4, and the proper posture as shown in FIG. 21B is obtained.

When the pusher plate 3 described later descends, as shown in FIG.
8 to the plunger 18 by energizing the solenoid 18a.
b and the slider pressing member 18c move rightward from the standby position, and the slider 17 moves rightward from the standby position against the urging force of the coil spring CS by the pressing of the slider pressing member 18c. For this reason, the chip component P above the slider 17 is moved downward by the slider 1.
7 and stops at a position corresponding to the inspection pin moving hole 1a13. Almost simultaneously with the stop, the power supply to the solenoid 16a of the third actuator 16 moves the plunger 16b and the two inspection pins 15 rightward from the standby position, and the two inspection pins 15 move to the third linear portion 1a5.
Each tip of the chip component P comes into contact with the external electrode Pe of the chip component P in a stopped state. Although not shown, a device for inspecting component characteristics is connected to the two inspection pins 15. For example, when the chip component P is a chip capacitor, the device is based on an electric signal from the inspection pin 15. The capacitance value is instantly inspected, and when the chip component P is a chip resistor, the resistance value is instantly inspected based on an electric signal from the inspection pin 15.

When the above-described characteristic inspection is completed, the energization to the solenoid 18a of the fourth actuator 18 and the solenoid 16a of the third actuator 16 is stopped, and the slider 17 and the inspection pin 15 return to the standby position shown in FIG. The chip component P after the characteristic inspection stopped by 17 enters the storage hole 17a.

As a result of the characteristic inspection, the inspected chip component P
19, the slider pressing member 18c is moved rightward by energizing the solenoid 18a of the fourth actuator 18, and the slider 17 is moved by the pressing of the slider pressing member 18c, as shown in FIG. It moves rightward from the standby position against the urging force of CS. As a result, the storage hole 17a of the slider 17 matches the upper end of the fourth curved portion 1a6 of the component passage 1a,
The chip component P (a chip component with good characteristics) in 7a is sent to the fourth curved portion 1a6. At this time, since the downward movement of the subsequent chip component P is restricted by the slider 17, the same characteristic inspection as described above is performed on the subsequent chip component P.

On the other hand, if the characteristic of the inspected chip component P is defective as a result of the characteristic inspection, as shown in FIG.
The energization of the solenoid 19a of the fifth actuator 19a is stopped, and the plunger 19b and the regulating member 19c are moved leftward in the figure by the biasing force of the built-in spring, and the slider pressing member 18c whose position regulation by the regulating member 19c has been released and The plunger 18b is moved leftward in the figure by the biasing force of the built-in spring, and
The slider 17 whose position regulation by c has been released moves leftward in the figure by the urging force of the coil spring CS. As a result, the storage hole 17a of the slider 17 protrudes out of the chute plate 1, and the chip component P in the storage hole 17a.
(Chip components with poor characteristics) are excluded outside the component passage 1a. Storage hole 17 that protrudes out of shoot plate 1
If a box is arranged below “a”, chip components P having poor characteristics can be collected. At this time, since the downward movement of the subsequent chip component P is restricted by the slider 17, the same characteristic inspection as described above is performed on the subsequent chip component P.

As described above, the characteristic inspection is sequentially performed on the chip components P in the component passage 1a, and the chip component P having the defective characteristic is removed out of the component passage 1a.

The chip component P having good characteristics sent into the fourth curved portion 1a6 of the component passage 1a passes through the fourth curved portion 1a6 while undergoing the same correcting action as described above. In the process of passing through 1a6, the direction is changed from portrait to landscape.

The chip component P after being changed to the horizontal direction is pushed rightward so as to sequentially pass through the fourth linear portion 1a7, the fifth linear portion 1a8, and the sixth linear portion 1a9 while being pushed by the subsequent chip component P. Go to

Since the thickness dimension of the fifth straight portion 1a8 gradually decreases to the right, the third curved portion 1a8
Even when the posture of the chip component P is disturbed as shown in FIG. 21A when the chip component P from a6 passes through the fourth linear portion 1a7, the chip component P remains in the fifth linear portion 1a8.
When the vehicle passes through, the posture is corrected by contacting the inclined upper surface of the fifth linear portion 1a8, and the proper posture as shown in FIG. 21B is obtained.

The chip component P from the fifth linear portion 1a8 passes through the sixth linear portion 1a9, and the leading chip component P comes close to the permanent magnet 4 as shown in FIG. , And is attracted and held with its end surface in contact with the exposed surface of the permanent magnet 4. Subsequent chip components P are connected without gaps after the leading chip component P. In the standby state, as shown in FIG. 22, the lower surface of the distal end portion 3a of the pusher plate 3 is located at the same height as the upper surface of the distal end of the component passage 1a.
Since the left edge of the tip 3a of the pusher plate 3 is chamfered 3a1 or rounded to prevent the chip component P from being caught, even if the tip 3a is slightly lowered, the permanent magnet 4 Of the chip component P attracted to the front end 3a. Further, since the component holding force of the permanent magnet 4 is larger than the weight of one chip component, the leading chip component P adsorbed by the permanent magnet 4 maintains the state of FIG. 22 without dropping its own weight from the component discharge port 1b. I do.

When the second actuator 14 is operated to lower the pusher plate 3 in the state shown in FIG.
As shown in FIG. 3, the leading chip component P attracted and held by the permanent magnet 4 is pushed downward by the tip portion 3a and moves, and the chip component P is discharged from the component discharge port 1b to the outside in the horizontal posture. Is done.

If the lowering speed of the pusher plate 3 is equal to or higher than the falling speed of the chip component P by its own weight, the chip component P can be discharged to the outside while being in contact with the lower surface of the tip 3a. Also, since the surface of the component discharge port 1b and the surface of the pusher insertion port 1d on the same side as the end surface of the front end of the component passage 1a are on the same plane as the end surface of the front end of the component passage 1a, the pusher plate accompanying the component discharge 3 tip 3a
The movement of the chip component P and the movement of the chip component P can be performed smoothly, and the posture of the chip component P can be prevented from being disturbed during the component discharging process.

When the pusher plate 3 is raised and returned after discharging the components, as shown in FIG. 22, the entire following chip component moves under its own weight in the component passage 1a while receiving the same posture correcting action as described above. When the chip component P comes close to the permanent magnet 4, it is attracted by the magnetic force of the permanent magnet 4, and is attracted and held with its end surface in contact with the exposed surface of the permanent magnet 4. The succeeding chip component P continues after the leading chip component P without a gap.

That is, if the lowering and raising of the pusher plate 3 are repeated by the second actuator 14, the leading chip component P in the component passage 1a can be sequentially discharged from the component discharge port 1b in the horizontal position.

Therefore, as shown in FIG. 24, if the substrate S is arranged near the component discharge port 1b, the discharged component P can be mounted on the substrate electrode SE such as a land. In addition, since it is not necessary to transport the chip component by the suction nozzle and then mount it, unlike the related art, the component mounting time per component can be significantly reduced. If a paste-like joining material such as cream solder is applied on the substrate electrode SE in advance, the chip component P can be temporarily fixed by utilizing the viscosity of the joining material, and the discharged component P can be attached to the substrate S
It is also possible to press against. Further, if the above-described component discharge is performed while changing the relative position between the substrate S and the component supply device, the components can be mounted on the substrate S at a high-speed cycle.

Further, as shown in FIG. 25A, if the component packaging tape ET is arranged near the component discharge port 1b, the discharged component P is inserted into the storage recess ETa of the component packaging tape ET. It is not necessary to transport and insert the chip components by the suction nozzle as in the related art, so that the component insertion time per component can be greatly reduced. Also, if the above-described component ejection is performed while changing the relative position between the component packaging tape ET and the component supply device, the component can be inserted into the storage recess ETa at a high-speed cycle. Incidentally, the component packaging tape ET shown in FIG. 25A has a large number of storage recesses ETa at equal intervals in the length direction as shown in FIG. 25B, and the storage recess ETa after component insertion. Is covered with a cover tape CT which is removably adhered to the surface of the component packaging tape ET. The component packaging tape ET has guide holes ETa that engage with pins of a sprocket (not shown) for moving the tape at equal intervals in the length direction, and is moved in the direction of the arrow by a distance corresponding to the interval of the storage recess ETa. Move intermittently.

According to the above-described component supply apparatus, the chip components P stored in the component storage case 9 are moved one by one in the length direction by reciprocating the movable pipe 10b of the pipe mechanism 10 in the vertical direction. The chip component P can be taken into the component supply pipe 10a and sequentially sent to the component passage 1a through the component supply pipe 10a. In other words, the storage parts P in the parts storage case 9 can be accurately replenished to the parts passage 1a, the chip parts P in the parts passage 1a can be reliably prevented from being empty, and the discharge of the parts is interrupted. You can continue without doing.

Further, according to the above-described component supply apparatus, the first chip component P in the component passage 1a is sequentially discharged from the component discharge port 1b in the horizontal position by reciprocating the pusher plate 3 in the vertical direction. be able to.
Therefore, if the substrate S is arranged near the component discharge port 1b, the component is discharged while changing the relative position between the substrate S and the component supply device, so that the component mounting on the substrate S can be performed at a high speed cycle. It is also possible to carry out component mounting in an extremely fast cycle of 0.1 sec or less. Also, if the component packaging tape ET is arranged near the component discharge port 1b, the component is discharged while changing the relative position between the component packaging tape ET and the component supply device. Insertion can be performed in a high-speed cycle, and component insertion can be performed in an extremely fast cycle of 0.1 sec or less.

Further, according to the above-described component supply device, the chip component P which moves in the component path 1a toward the component discharge port 1b in accordance with the component discharging operation is moved to the slider 1
7 to stop sequentially at a predetermined position (inspection position) in the component passage 1a, and the external electrodes P of the chip component P in the stopped state
When the characteristic of the inspected chip component P is defective, the chip component P can be removed from the component passage 1a by the slider 17 if the characteristic of the inspected chip component P is defective. That is, the characteristic of the chip component P moving toward the component discharge port 1b in the component passage 1a is inspected immediately before the component discharge, and if the characteristic of the inspected chip component P is defective, the chip component P is removed. Since it can be accurately removed from the outside of the component passage 1a, it is possible to reliably prevent incorrect supply of chip components P with defective characteristics, and to perform a dedicated component inspection for inspecting component characteristics in a preliminary process. Eliminating the need for lines can greatly contribute to reducing equipment costs.

Further, since three curved portions 1a2, 1a4 and 1a6 are interposed in the middle of the component passage 1a, and two of them have different curved directions, the component passage 1a
The chip component P, which moves by its own weight downward in the inside, can be brought into contact with the two inner surfaces of the curved portions, particularly in the thickness direction, so that the posture can be accurately corrected, whereby the component movement in the component passage 1a can be extremely smoothly performed. Can be done. Therefore, even when the above-described component discharge cycle is accelerated, the component movement in the component passage 1a is reliably followed by the component discharge cycle, and the desired component discharge is performed satisfactorily without causing a defect. Can be. Further, since the posture of the chip component P in the component passage 1a can be optimized, the external electrode P
There is no possibility that the contact of the test pin 15 with the external electrode Pe is good, and the characteristic test can be reliably performed by making good contact of the test pin 15 with the external electrode Pe.

The above-described component supply device can handle electronic components other than the chip components shown in FIG. 6, for example, composite components such as LC filters and networks, and integrated circuit components such as semiconductor elements. Yes, it is fully possible to handle columnar electronic components.

Further, in the above-described component supply device, it is possible to discharge components even when the component supply device itself is slightly tilted, so that components can be mounted on an inclined board or a component packaging tape can be tilted. Can be fully adapted to the insertion of parts into the storage recess.

Further, in the above-mentioned component supply device, the slider pressing member 18c of the fourth actuator 18 for driving the slider is shown in contact with the slider 17, but as shown in FIG. 26, it is attached by the coil spring CS2. A biased rotatable buffer lever 18c1 may be provided on the slider pressing member 18c so that the buffer lever 18c1 contacts the slider 17. In this case, the force relationship between the coil spring CS1 for biasing the slider 17 and the coil spring CS2 is set to CS2> CS1. As shown in FIG. 27A, when the slider 17 is moved rightward in the figure against the urging force of the coil spring CS1 by pressing the buffer lever 18c1, the coil spring CS2 does not contract, but as shown in FIG. As shown in (B), when an overload is applied to the movement of the slider 17 for some reason, for example, the chip component is moved to the storage hole 17a.
When the slider 17 is inclined and clogged in the middle of entry, or when the slider 17 falls into a state where it is difficult to move due to intrusion of dust or the like, it is possible to prevent the coil spring CS2 from contracting and forcibly moving the slider 17.

FIGS. 28 to 31 show modified examples of the characteristic inspection means. In the figure, 21 is an inspection pin, 22 is a third actuator for driving the inspection pin, 23 is a stop rod, 24 is a fourth actuator for driving the stop rod, 25 is a holding rod, and 26 is a fifth actuator for driving the holding rod. It is.

The third straight portion 1a5 of the component passage 1a and the third straight portion 1a5
The curved portion 1a6 is continuous as shown in the figure, and a suction passage 1a14 for removing parts is formed on the inner surface of the third linear portion 1a5. The vertical dimension of the opening of the suction passage 1a14 is slightly larger than the length dimension Lp of the chip component P, and the horizontal dimension is equal to the thickness dimension of the third linear portion 1a5. In addition, a shutter 27 for opening and closing this opening is movably disposed at the opening position of the suction passage 1a14. Although not shown, the suction passage 1a14 is connected to an air circuit including a vacuum pump and the like, and the shutter 27 is connected to an actuator for driving a shutter, for example, a solenoid. Further, the third straight line portion 1
On the left side of a5, two inspection pin moving holes 1a16 are formed at intervals in the vertical direction. The inspection pin moving hole 1a16 has its left end opened on the left side of the chute plate 1, and its right end opened on the inner surface of the third linear portion 1a5. Further, a stop rod moving hole 1a17 is formed below the test pin moving hole 1a16, and a holding rod moving hole 1a18 is formed above the test pin moving hole 1a16.

The inspection pin 21 has a sharp shape with at least the tip formed of a conductive material, is movably inserted into the two inspection pin moving holes 1a16, and is located outside the chip component P to be inspected. Contact with each electrode Pe is enabled. Each inspection pin 21 is composed of a sharp pin body, a sleeve that houses the pin body, and a spring material that supports the pin body in the sleeve. That is, the pressure when the pin body contacts the external electrode Pe of the chip component P is reduced by the spring material, so that the external electrode Pe can be prevented from being damaged.

Third actuator 22 for driving inspection pin

And a stopper 22d for adjusting the stroke, and a support piece 22e for the stopper. The sleeves of the two inspection pins 21 are fixed to the pin support member 22c of the third actuator 22 so as to be parallel to each other with a space between them vertically. In the standby state, the tip ends of the two inspection pins 21 are inserted into the inspection pin moving holes 1a16, but the third linear portions 1a of the component passages 1a.
5 does not protrude.

The stop rod 23 has at least a distal end formed of a non-magnetic material, has a rounded distal end, and is movably inserted into the stop rod moving hole 1a17.

Fourth actuator 2 for driving stop rod
Reference numeral 4 denotes a solenoid 24a disposed on the lower surface of the device base 11 via a bracket common to the third actuator 22, a rod support member 24c connected to a plunger 24b of the solenoid 24a, and a stroke adjusting stopper 24d. , And a stopper support piece 24e. The stop rod 23 is fixed to the rod support member 24c of the fourth actuator 24. In the standby state, the end of the stop rod 23 is inserted into the stop rod moving hole 1a17, but does not protrude into the third linear portion 1a5 of the component passage 1a.

The holding rod 25 has at least a tip made of a non-magnetic material, has a rounded tip, and is movably inserted into the holding rod moving hole 1a18. If a spring support structure similar to that of the inspection pin 21 is employed for the holding rod 25, the pressure when the holding rod 25 presses and holds the chip component P is relieved by the spring material, and the chip component P is damaged by pressing. Can be prevented.

The fifth actuator 26 for driving the holding stop rod includes a solenoid 26a disposed on the lower surface of the apparatus base 11 through a bracket common to the third actuator 22, and a rod connected to a plunger 26b of the solenoid 26a. It is composed of a support member 26c, a stopper 26d for stroke adjustment, and a support piece 26e for stopper. The holding rod 25 is fixed to the rod supporting member 26c of the fifth actuator 26. In the standby state, the tip end of the holding rod 25 is inserted into the holding rod moving hole 1a18, but does not protrude into the third linear portion 1a5 of the component passage 1a.

When the aforementioned pusher plate 3 is lowered, as shown in FIG. 29, the stop rod 23 moves rightward in the figure by energizing the solenoid 24a of the fourth actuator 24 and moves into the third linear portion 1a5. Since the chip component P has entered, the chip component P stops moving downward.
3 and stops at the position corresponding to the inspection pin moving hole 1a16. Almost simultaneously with the stop, the two inspection pins 21 enter the third linear portion 1a5 by energizing the solenoid 22a of the third actuator 22, and the respective tips contact the external electrodes Pe of the chip component P in the stopped state. I do. Although not shown, a device for inspecting component characteristics is connected to the two inspection pins 21. For example, when the chip component P is a chip capacitor, the device is based on an electric signal from the inspection pin 21. The capacitance value is instantly inspected, and when the chip component P is a chip resistor, the resistance value is instantly inspected based on an electric signal from the inspection pin 21.

As a result of the characteristic inspection, the inspected chip component P
In the case where the characteristic is good, first, as shown in FIG. 30, the energization of the solenoid 26a of the fifth actuator 26 causes the holding rod 25 to enter the third linear portion 1a5, and the chip component P on the upper side of the inspection component. Are pressed and held at the same position, and the subsequent components are prevented from falling. And the third
The inspection pin 21 returns to the standby position by stopping the power supply to the solenoid 22a of the actuator 22, and the stop rod 23 returns to the standby position by stopping the power supply to the solenoid 24a of the fourth actuator 24. A chip part having good characteristics is sent to the fourth curved portion 1a6. The chip component P after the inspection is the fourth curved portion 1
After being sent to a6, the stop rod 23 enters the third linear portion 1a5, and the holding rod 25 returns to the standby position, and the same component inspection as described above is repeated.

On the other hand, as a result of the characteristic inspection, when the characteristic of the inspected chip component P is defective, as shown in FIG.
First, when the solenoid 26a of the fifth actuator 26 is energized, the holding rod 25 enters the third linear portion 1a5, and the upper chip component P of the inspection component is held at the same position. You. And
When the power supply to the solenoid 22a of the third actuator 22 is stopped, the inspection pin 21 returns to the standby state. Next, the shutter 27 is moved rightward by the operation of the actuator, and the opening of the suction passage 1a14 is opened.
Chip component P after inspection by negative pressure acting on a14
(A chip component having a poor characteristic) is sucked into the suction passage 1a14 and is discharged out of the component passage 1a. After the inspected chip component P is removed out of the component passage 1a, the holding rod 25 returns to the standby position, and the same component inspection as described above is repeated.

According to the structure shown in FIGS.
The characteristics of the chip component P moving toward the component discharge port 1b in the component passage 1a are inspected immediately before the component discharge. If the characteristics of the inspected chip component P are defective, the chip component P is removed. Since it is possible to accurately remove the chip component P with a defective characteristic from being erroneously supplied to the outside of the passage 1a, a dedicated component inspection line for inspecting the component characteristic in a preliminary process can be surely prevented. And can greatly contribute to reduction of equipment costs.

FIG. 32 shows a modification of the part discharge port.
In this embodiment, an air suction hole 1k is provided instead of the permanent magnet 4 in the component supply device.
A tube from an air circuit (not shown) equipped with a vacuum pump or the like is connected to k. The leading chip component P that moves in the component passage 1a is attracted by the suction force of the air suction hole 1k when it comes close to the air suction hole 1k, and its end surface is in contact with the end surface of the tip of the component passage 1a. Is held by suction. To further stabilize the posture of the leading chip component P in the discharge standby state, the air suction holes 3 reaching the lower surface of the tip portion 3a of the pusher plate 3 are formed.
e is formed, and the suction force of the air suction hole 3e may be used to assist the suction and holding of the leading chip component P. If the suction force of the air suction hole 3e is released after the component is discharged by the pusher plate 3, the tip 3a can be separated from the component without any problem.

[0103]

As described in detail above, according to the present invention,
The characteristics of the electronic components that move toward the component outlet in the component passage are inspected immediately before component ejection, and if the characteristics of the inspected electronic components are defective, this electronic component is accurately removed out of the component passage. Therefore, even when the component supply cycle is accelerated, it is possible to reliably prevent erroneous supply of an electronic component P having a defective characteristic, and to provide a dedicated component for inspecting the component characteristics in a preliminary process. Eliminating the need for a component inspection line can greatly reduce equipment costs.
