Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for correcting the posture of electronic components, and in particular, a pocket groove formed on the outer periphery of a rotating shifting ring is used to adjust the polarity of electronic components such as capacitors. This invention relates to a posture correction device for electronic components that can be sent out in the same orientation.

[Technical background and problems of the invention]

In order to send electronic components such as capacitors stored in a vibrating bowl feeder at regular intervals,
A coordinating ring, commonly known as a cornice wheel, is used.
This transfer ring has a large number of pocket grooves formed at a constant pitch on its outer circumferential surface, and electronic components are placed at regular intervals by storing components in these pocket grooves and rotating the transfer ring. It can then be sent out. The capacitors to be supplied into the pocket grooves of the shunting ring are randomly supplied directly above the supply position on the shunting ring. As a result, the polarity of the leads of the capacitors housed in the pocket groove of the transport ring was uneven, with the anode lead leading in the direction of movement, and the cathode lead leading the other way. . This caused various troubles in subsequent steps. In order to prevent this problem from occurring, the orientation of the capacitors, which have different polarities, must be corrected in advance, which has been an obstacle to improving work efficiency.

[Purpose of the invention]

Therefore, an object of the present invention is to correct the direction of the capacitor so that the polarity direction of the electronic components randomly supplied into the pocket groove of the shunting ring is adjusted so that the longer lead leads during transportation by the shunting ring. To provide an apparatus for correcting the posture of electronic components, which can be sent to the next process with the polarities aligned.

[Summary of the invention]

In order to achieve the above object, the present invention provides an electronic component in which a plurality of pocket grooves are formed at regular intervals on the outer periphery of a transfer ring, and two leads with different leg lengths are provided in these grooves. This method corrects the posture of electronic components by rotating the feeding ring while storing the electronic components in a lying position, aligning the long and short directions of the leads of the electronic components so that the longer leads, and then sending them out at regular intervals. In the device: A lift cam that continuously forms an upwardly sloped part, a central flat part, and a downwardly sloped part is provided on the movement path of the lead with the longer leg, and the lead with the longer leg is located inside the downwardly sloped part of this lift cam. The first part attracts only the short lead and applies braking.
A second magnet is placed outside and in front of the first magnet to attract only the lead with the longer leg.

[Embodiments of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an electronic component posture correction apparatus according to the present invention will be described below with reference to the drawings.

In FIG. 1, the reference numeral 1 designates a vibrating bowl feeder, which is known per se and has a spiral-shaped vibrating bowl 2, and inside the vibrating bowl 2 there is a vibrating bowl 2 which is disposed from the bottom toward the outer periphery. A spiral feed track 3 is formed. The lower surface of the vibrating bowl 2 is equipped with an electromagnet that generates electromagnetic vibration for transporting parts, a vibrating plate spring that supports the bowl and converts it into vibration for transport, and a controller. Therefore, when the electromagnet is energized, the capacitor stored in the vibrating bowl 2 can be delivered along the feed track 3 from the inside to the outside.

Therefore, at the outlet end of the feed track 3,
A parts sorting device, generally designated by numeral 5, is provided,
This parts sorting device 5 is equipped with a sorting ring 6 commonly called a cornice wheel, and a plurality of pocket grooves 7, 7, . There is. The size of this pocket groove 7 is
For example, the size is set such that electronic components such as the capacitor 8 can be accommodated in a lying position. That is, the main body 9 of the capacitor 8 is accommodated in the pocket groove 7, and the anode lead 10a and the cathode lead 10b are protruded outward in the radial direction in a lying position.
Incidentally, the capacitor 8 treated according to the present invention
The leg lengths of the anode lead 10a and the cathode lead 10b are different, and the anode lead 10a is usually set longer than the cathode lead 10b.

The sending ring 6 is placed on a table 11 of a vibrating bowl feeder, and is given a clockwise rotational motion as shown by the arrow when vibrating. As a result, a large number of capacitors 8 are accommodated in the pocket grooves 7, 7, .

According to the present invention, the posture correction device 12 disposed on one area of the feeding ring 6 allows the anode lead 10a with long legs to lead in the direction of travel, and the cathode lead 10b with short legs to follow. It can be aligned in such a direction.

The posture correction device 12 has an anode lift cam 14 that acts only on the long-legged anode lead 10a, and this lift cam 14 is fixed to the side surface of the table 11 with screws 15. The lift cam 14 includes a cam surface 19 in which an upwardly inclined portion 16, a central flat portion 17, and a downwardly inclined portion 18 are continuously formed from the inlet side toward the outlet side. This cam surface 19 needs to be located on the moving path of the tip of the anode lead 10a.

On the other hand, a sector-shaped restraining plate 20 is arranged in a predetermined area on the sending ring 6 inside the lift cam 14. This restraining plate 20 closes the upper openings of the pocket grooves 7, 7, . The above-mentioned lift cam 14 and restraining plate 20
The cam surface 19 of the lift cam 14
The long anode lead 10 of the capacitor 8
As is clear from FIG. 3, when a slides, the cathode lead 10b is moved in the direction of the arrow while remaining in a downward position under the influence of gravity.

On the other hand, the short cathode lead 1 of the capacitor 8
0b is on the moving path and the lift cam 14
A segment-shaped first magnet 21 is arranged inside the downwardly inclined portion 18 . This first magnet 21 has the function of attracting the short-legged cathode lead 10b in the middle of the downward slope section 18 to provide a braking action. It is configured. Furthermore, a second magnet 22 is disposed on the outside of the first magnet 21, preferably in substantially the same plane so as to partially overlap in the circumferential direction of the first magnet 21. Therefore, the capacitor 8 attempts to rotate counterclockwise around the cathode lead 10b attracted to the first magnet 21, and immediately after the anode lead 10a passes the end point of the downwardly inclined surface 18 of the cam surface. The anode lead 10a is attracted by the second magnet 22, and as a result, the anode lead 10a is in a leading position. In this way, capacitor 8
In this case, the long-legged anode lead 10a is connected to the second magnet 2.
2, while the cathode lead 10 with short legs
b remains attracted to the first magnet 21 and rotates clockwise together with the adjustment ring 6 in FIGS. 1 and 2. Thereafter, the bases of the anode and cathode leads 10a, 10b of the capacitor 8 are supported by the support guide 28.

Therefore, after the posture correction device 12,
A device 23 is arranged to change the orientation of the capacitor 8 from a lying position to an upright position. This conversion device 23 has a deflection plate 24, which includes:
The deflection plate 24 is arranged so as to form a circumferential gap 25 between it and the adjustment ring 6, and a deflection plate 24 that changes from a substantially horizontal plane to a vertical plane is formed on a part of the peripheral edge of the table 11 from near the entrance to the center of the deflection plate 24. A surface 26 is formed, and the anode lead 10a and cathode lead 10b of the capacitor 8 drop down the leads 10a, 10b along this deflection surface 26, and are gradually converted to an upright position. As shown, the capacitor 8 is completely converted to the upright position. Then, the capacitors 8, 8, .

Since the present invention is constructed as described above, when the vibrating bowl feeder 1 is driven to vibrate, the capacitor 8 in the bowl is conveyed from the inside to the outside along the feeding track 3. On the other hand, when the table 11 is vibrated and driven in synchronization with the driving of the vibrating bowl feeder 1, the vibration is propagated to the shuffling ring 6, and the shuffling ring 6 rotates continuously in the clockwise direction. A large number of capacitors 8 are then randomly supplied by gravity falling from the feeding station into the pocket groove 7 of the sending ring 6. The polarities of the capacitors 8 accommodated in the pocket groove 7 are uneven, and the anode lead 10a may be in front in the direction of movement, and conversely, the cathode lead 10b may be in the lead. . In any case, as the sending ring 6 rotates in the direction of the arrow, the anode lead 1 of the capacitor 8
0a rides on the upwardly inclined surface 16 of the cam surface 19 of the lift cam 14, and is sent in the direction of the arrow while sliding on the cam surface.

During this time, the cathode lead 10b moves downward under the action of gravity, as is clear from FIG. 3, and the main body 9 of the capacitor 8 rotates slightly within the pocket groove 7.
When the cathode lead 10b reaches directly above the first magnet 21, it is attracted downward under the influence of the magnetic attraction force, and the cathode lead 10b is finally attracted by the first magnet 21. Then, the anode lead 10a is connected to the downward slope portion 1 of the lift cam 14.
8, the cathode lead 10b is attracted to the first magnet 21 and receives a stronger braking force, while the anode lead 10a is attracted and adsorbed by the second magnet 22, and the capacitor 8 In the figure, the anode lead 10a is rotated counterclockwise so that the anode lead 10a is sent first.

Note that in the above embodiment, the first and second
Although the magnet is made of magnetic rubber, the present invention is not limited to this and may be made of an electromagnet, in which case the magnitude of the attractive force can be adjusted.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, while the electronic component is accommodated in the pocket groove of the transfer ring and sent in the circumferential direction, the lead on the longer leg side is moved along the cam surface of the lift cam. While lifting, the first magnet attracts and adsorbs the lead with the shorter legs and moves it forward while applying braking, and the second magnet actively moves the lead with the longer legs just after passing the exit of the downward slope of the lift cam surface. The lead with longer legs can be adsorbed to the target and placed ahead of the lead with shorter legs in the direction of travel, and while the lead with longer legs passes through the posture correction device, the lead with longer legs will correct its posture and proceed to the subsequent process. Can be transported.
