Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic component feeding device, and in particular, to smoothly move electronic components in an aligned state in which a plurality of lead wires of different lengths protrude in the same direction. The present invention relates to an electronic component feeding device that allows short lead wires to be easily aligned in a predetermined direction and transferred to the next process.

Generally, lead wires for electronic components such as capacitors are made of copper-plated iron wire and then metal-plated with tin, solder, or leaded tin, and there are at least two wires on each side of the component body. They are pulled out in opposite directions or in the same direction from one side. Among components whose lead wires are drawn out in the same direction, the length of the lead wires of capacitors, especially polar electrolytic capacitors, differs depending on the polarity.

FIG. 1 shows a cross section of an electrolytic capacitor, in which an electrolytic capacitor 1 has a capacitor element 2 connected to an anode lead wire 3. Cathode lead wires 4 are drawn out through tab terminals 3a and 4a, and 11 people are placed inside a case 5 having an opening using a sealing member 6 made of rubber or the like.

Such an electrolytic capacitor is manufactured in the following manner. An aluminum wire is welded to the aforementioned lead wire, and a portion of this aluminum wire is pressed to flatten it to form a lead tab terminal. The lead tab terminal thus formed to be connected to the lead wire is mechanically and electrically connected to an aluminum electrode foil for anode which has been cut to a predetermined width and has an anodic oxide coating by caulking, crimping or welding, and then A counter electrode foil having a lead wire terminal is wound together with the above-mentioned anode electrode foil with a separator paper interposed therebetween to form a capacitor element. This element is impregnated with electrolyte, inserted into an aluminum case, and sealed with a rubber backing or the like. Furthermore, the finished product goes through an aging process that lasts from several minutes to several hours before being turned into a product. In this aging process, in the case of a polar electrode, the anode side is aged,
In the case of non-polar electrolytic content 4, both electrodes are aged, but in either case, by applying a voltage with the impregnated electrolyte on the cathode side, the surface of the aluminum electrode foil and the aluminum electrode foil of the lead wire tab terminal can be aged. The damaged parts of the oxide film on the connecting parts and the aluminum electrode foil are reformed, the oxide film is generated and repaired, and the product is manufactured by aging until a predetermined leakage current value is obtained.

By the way, in order to supply finished products to such an aging process, it is necessary to align the polarities of the lead wires in the same direction and insert them one by one into the aging sorter.

Conventionally, a supply mechanism as shown in FIG. 2 has been used to supply components such as the electrolytic capacitor 1 to the ging process. This feeding mechanism includes a parts feeder 7, a sub feeder 8. Linear feeder 9° rotor 10 and product holder 1
1, a polarity detection section 12 attached to a product holder 11, and a 180° rotation section 3 at each holder position. The parts feeder 7 stores a large number of parts and feeds them one by one to the sub-feeder 8 at the next stage by vibration etc. In the sub-feeder, the lead wire direction is almost aligned and the lead wire direction to the next stage linear feeder 9 is -1-1. Supply towards the direction. The linear feeder 9 is formed in the shape of a gutter with an open upper side, and the parts are moved in four parts formed along the longitudinal direction in a line with the lead wires facing upward. Then, the aligned parts are supplied one by one to the rotor 10 in this state, and the lead wire interval is widened.

Next, the products are transferred to the product holder 11 and aligned one by one at regular intervals. At this point, the lead wire moves in an upward direction like the linear feeder 9 described above. On the travel path of the product boulder 11, there is a polarity detecting section 12 consisting of a direction plate 12a, a polarity detection rod 12b, and a micro switch 12C as shown in FIGS. 12a is arranged at a position corresponding to the true position of the component, and a slit is formed on one side of the direction plate 12a, and the tip of the polarity detection rod 12b is rotatably inserted into this slit for detection. The microswitch 12c is turned on and off by rotating the rod 12b. When the component 15- moves together with the product holder 11 to the polarity detecting section 12, the direction plate 12a is inserted between the two spread lead wires 3 and 4. At this time, when the two lead wires 3.4 are placed on both sides of the direction plate 12a with the two lead wires 3.4 facing in the normal direction as shown in FIG. When the rod 12b passes through the rod 12b without touching it and is facing in the opposite direction as shown in FIG. is turned on and 180 is in the next holder position.
'The rotating part 13 rotates to align the lead wires 3.4 in the normal direction.

However, with the above-mentioned feeding device, when the component 1 moves through the linear feeder 9, it may fall down in the direction of movement, resulting in problems such as not being smoothly supplied to the next rotor 10, or failure to transfer the component 1 to the rotor 10 properly. This is likely to occur, and the rotor 1 is required to align the polarity on the product holder 11.
0 had the disadvantage of having to widen the one-dot line spacing in advance.

= 6- In view of these circumstances, the present invention makes it possible to smoothly move electronic components having lead wires drawn out in the same direction to the next process with the lead wire directions aligned, and also to easily align the polarity of the lead wires. An object of the present invention is to provide an electronic component supplying device that can perform the following steps.

The device of the present invention arranges magnetic force means near the lead wires of electronic components moving along a supply path so that the parts can be aligned and moved without falling over, and further combines the magnetic force means and a separation plate to prevent the parts from falling over. Configure so that lead polarity alignment can be performed.

Embodiments of the present invention will be described below based on the drawings.

4 and 5 relate to the first embodiment of the present invention, FIG. 4 is a perspective view showing the feeding process from the parts feeder to the linear feeder, and FIG. 5 is an enlarged view of the main part of FIG. 4. FIG.

In these figures, numerals 14, 15, and 16 indicate a parts feeder, a sub feeder, and a linear feeder, respectively, and the parts feeder 14 has two lead wires 1 in the same direction.
A large number of capacitors 19 having 7.18 are stored and supplied one by one to the next stage sub-feed 'g15, and then supplied to the next stage linear feeder 16 with the lead wires 17 and 18 almost aligned in the sub-feeder 15. . The linear feeder 16 is formed in the shape of a gutter with an open upper side, and a magnetic plate (magnet) 21 is provided above the recess 20 formed in the longitudinal direction substantially parallel to the feeder. Concave portion 20 of linear feeder 16
A capacitor 19 is supplied from the sub-feeder 15 to the capacitor 19 with its lead wires 17 and 18 facing upward.

In the above configuration, the linear feeder 16 is connected to the capacitor 19
When the lead wire moves straight in the direction shown by arrow A with the lead wire direction upward, the magnetic plate 21 is placed on the extension of the lead wire 17°18, so the magnetic force moves the lead wire 1.
7.18 is pulled upward, and the capacitor 19 moves straight without falling over.

In the above example, an electrolytic capacitor is illustrated in which Miki's lead wires of different lengths are drawn out in the same direction as an electronic component, but the electronic components to be moved are not limited to capacitors, but also include multiple wires in the same direction. Any component with lead wires drawn out may be used.

FIG. 6 is a perspective view showing a polarity detection process on a product holder according to a second embodiment of the present invention.

In this figure, numeral 22 indicates a product holder,
One capacitor 19 is connected to the lead wire 17 on the tray.
18 is directed upward and is conveyed in the direction of arrow B. In this case, the lead wires 17, 18 have different lengths for each polarity. A polar separation plate 23 is provided above the product boulder 22 to determine the length of the lead wires 17 and 18. This polarity separation plate 23 is perpendicular to the lead wire extraction surface of the capacitor 19 and the short lead wire 18
The distal end thereof is curved in a direction perpendicular to the direction in which the parts travel. Further, a magnetic plate (magnet) 24 is arranged on the curved side of the polar separation plate 23 so as to be substantially parallel to the separation plate 23.

In the above configuration, when the capacitor 19 is conveyed in the direction of the arrow B, the long lead wire 17 will touch the curved part of the polarity separation plate 23 no matter which direction the lead wires 17 and 18 are oriented. The short lead wire 18 runs on one side of the separation plate 23 while being guided by the curved surface of the magnetic plate 2.
4 to the other side of the separating plate 23. Therefore, the polarity of the long lead wire, ie, the anode lead side, and the short lead wire, ie, the cathode lead side, are aligned in polarity. According to such a polarity detection step, it is possible to perform polarity alignment without having to set the lead wires 17, 18 in advance and spread them apart. Therefore, when combined with the embodiment described above, the rotor 10 in the capacitor supply process shown in FIG. 2 becomes unnecessary, and the capacitor can be directly supplied from the linear feeder to the product holder.

Note that in the above embodiment, Miki lead wires of different lengths were arranged, but for parts with Miki lead wires or more, for example, one Miki lead wire is long and one short. You can distinguish the merits and demerits even in the case of

As described above, according to the present invention, a magnetic force means is disposed near the lead wires of the supply path for moving a large number of components having lead wires drawn out in the same direction so that the lead wire directions are aligned. In addition, in combination with a separation plate, it is possible to determine the length of the lead wires, which prevents the parts from falling during the process of aligning and moving the parts, and also makes it possible to easily align the polarity of the component lead wires. . Therefore, for example, in the process of supplying an electrolytic capacitor to an aging process, the flow of the capacitor becomes smooth, and processes such as widening the lead wire interval for polarity determination can be eliminated, and the process can be simplified.
