Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic component sorting device, and in particular, to a sorting device for electronic components such as a variable resistor that is sent out from a vibrating bowl feeder with the lead portion facing downward. The present invention relates to an electronic component sorting device that uses magnetic attraction to sort out items with the same orientation.

[Technical background of the invention and its problems]

Generally, vibrating bowl feeders are widely used when feeding electronic components such as variable resistors stored in a hopper to a place of use. According to this vibratory bowl feeder, electronic components such as variable resistors stored in the bowl are fed from the inside to the outside on the spiral feeding track by electromagnetic vibration. Further, when it is necessary to transport parts to a location away from the vibratory bowl feeder, a linear feeder of an appropriate length is connected to the outlet side of the bowl feeder.

By the way, the postures of the electronic components sent from the vibrating bowl feeder are different, and the electronic components are sent in different orientations in a random state. However, when inserting electronic components into a printed circuit board in the next process, it is necessary to align the polarity, so it is necessary to unify the orientation of the electronic components fed on the feeding track of the linear feeder. . For this reason, it is desirable to sort out and send out only electronic components oriented in the same direction at the exit of the vibrating bowl feeder.

In addition, the electronic component has a head and legs,
For example, in the case of electronic components such as transistors and variable resistors that have thin lead wires protruding from the main body, it is better to transport them in an upright position with the lead wires facing downward when transporting them using a straight feeder. Easy to perform various treatments in the next process.

[Purpose of invention]

Therefore, the purpose of this invention is to focus on the fact that the lead wires of electronic components that are vibrated and transported in a random state on a feeding track are made of magnetic material, and to utilize the effect of magnetic attraction to generate magnetic attraction. To provide an electronic component sorting device which allows only electronic components facing in a certain direction with a strong resistance to pass through and rejects electronic components facing the opposite direction by dropping from a feeding track.

[Summary of the idea]

In order to achieve the above object, the present invention is an electronic component in which a plurality of lead wires protrude from the main body, and a part of the lead wires is buried in a biased manner close to one of the opposing sides of the main body. The bottom surface of the main body is supported on the support track of the feeding track, the lead wire is placed on the inclined track, and the electronic component is moved forward by vibration action, and the orientation of the electronic component is adjusted on the feeding track. In a sorting device for electronic parts, the sorting means includes an exclusion groove that is a part of the inclined track of the feeding truck and is cut out through a portion through which the lead wire passes; There is a support plate that rises from the upper support track surface and one side of the main body of the electronic component slides on it, and a lead wire of the electronic component that is installed near the surface of this support plate and moves forward in the normal direction. The device is characterized by comprising an attraction and holding device including a permanent magnet piece that attracts the upper end.

[Example of idea]

Embodiments of the electronic component sorting apparatus according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 designates a vibrating bowl feeder, which is of a type known per se, and has an inner conical vibrating bowl 2.
A spiral bowl track 3 is formed in the vibrating bowl 2 from the bottom toward the outer periphery. The lower surface of the vibrating bowl 2 includes an electromagnet that generates electromagnetic vibration for transporting parts, and a diaphragm spring that supports the bowl and converts it into vibration for transportation.
Equipped with a controller. Therefore,
When the electromagnet is energized, the variable resistor 4 stored in the vibrating bowl 2 can be sent out along the bowl track 3 from the inside to the outside.

The configuration of the variable resistor 4 will now be explained with reference to FIG. 2. The variable resistor 4 has a main body 5 and three lead wires 6 protruding from the bottom of the main body 5. There is. These lead wires 6 are made of a magnetic material, and a lead wire buried portion 6a buried in the main body portion 5 is bent into the shape of a key and one side surface 5 is bent.
It is located close to a. The present invention was devised by focusing on the fact that a part of the lead wire 6 of the main body part 5 is buried in one side surface 5a of the main body part 5.

A feeding track 8 is extended on the exit side of the feeding track.
The support track 10 supports the inclined track 9 inclined with respect to the horizontal plane and the bottom surface of the main body 5 of the variable resistor 4.
It is composed of. The height of the inclined track 9 is set to about 4/5 of the length of the lead wire 6,
As shown in the figure, the bottom surface of the main body 5 of the variable resistor 4 contacts the support track 10, while the lead wire 6 slides on the inclined track 9 and is vibrated in the direction of the arrow.

A part of the inclined track 9 is cut out to form an exclusion groove 11 through which the variable resistor 4 in an irregular orientation can be dropped and removed.

A support plate 12 is provided on the outer peripheral edge of the feed track 8 in the region including the exclusion groove 11 and projects obliquely upward. A suction holding device 14 for the main body 5 of the variable resistor 4 is provided on the upper surface of the support plate 12 . This suction holding device 14 is a permanent magnet piece 1
5, and the permanent magnet piece 15 is connected to the case 1.
A protection plate 17 made of a magnetically permeable material is attached to the lower surface of the case 16. Both the case 16 and the protection plate 17 are preferably made of 18-8 stainless steel.

Since the present invention is constructed in this way, when the vibrating bowl feeder 1 is driven to vibrate, the variable resistor 4 in the bowl is vibrated and transported from the inside to the outside along the bowl track 3. A group of variable resistors 4, 4, transferred from the bowl track 3 to the feed track 8;
... 4 are vibrated and transported in a random state on the feed track 8 toward the exit side with the lead wire 6 facing downward and the main body 5 facing upward. At this time, the main body 5
is supported on the upper surface of the support track 10, and the three lead wires 6 are sent face down on the raceway surface of the inclined track 9, so the variable resistor 4 has the lead wire buried portion 6a closest to the support plate 12. Two positions can be taken at random: a normal state appearing on one side and an irregular state appearing on the opposite side. As shown in FIG. 3, the variable resistor 4, which has been vibrated and transported in the normal state where the lead wire buried portion 6a is closest to the surface of the support plate 12, has the attraction force of the permanent magnet piece 15 on the lead wire. The variable resistor 4 acts effectively on the buried portion 6a and advances while being held in an adsorbed state, so that the variable resistor 4 can be smoothly transferred on the feeding track 8 without falling even when passing through the exclusion groove 11.

On the other hand, in the variable resistor 4 that has been vibrated and transported in an irregular state, the lead wire buried portion 6a in the main body portion 5 exists at a position farthest from the surface of the support plate 12,
The magnetic attraction force of the permanent magnet piece 15 is weak. Therefore, the variable resistor 4 falls into the exclusion groove and is removed as shown in FIG.

Therefore, among the variable resistors 4 vibrating and transported in a random state on the feeding track 8, only the variable resistors 4 with the lead wire buried portions 6a facing inward are attracted by the permanent magnet pieces 15 of the attracting and holding device 14. The variable resistor 4, which is held by a force and transported by vibration, cannot maintain its upright position due to its weak magnetic attraction force, and falls down through the removal groove 11 and is removed.

Although the above embodiments have been described using a variable resistor as an example of an electronic component, the present invention is not limited thereto, and can be widely applied to electronic components having similar configurations.

[Effect of idea]

As is clear from the above explanation, according to the present invention, since the suction holding device including the permanent magnet piece is arranged on the support plate through which the main body of the electronic component that is sent under the vibration effect passes, the main body of the electronic component is Using the difference in the magnetic attraction between the lead wires buried inside the unit and the permanent magnet piece, electronic components facing the same direction are allowed to pass through, electronic components facing the opposite direction are allowed to fall, and electronic components facing the same direction are removed. can be transported to the desired location using the vibration transport effect.
