Description

[Detailed description of the invention] The invention relates to an automatic insertion machine that separates a ladder-shaped series of electronic components, which is made up of a large number of electronic components connected in a ladder shape, into individual electronic components and inserts them into a printed circuit board, etc. In particular, the present invention relates to a feeding device for feeding a ladder-shaped series of electronic components into an automatic insertion machine.

Some electronic components, such as capacitors, that have two leads are connected in a ladder shape and supplied to an automatic insertion machine. After such a ladder-shaped series of electronic components is fed into an automatic insertion machine, they are cut into individual electronic components using a cutter and mounted on a printed circuit board or the like.

FIG. 1 shows the case of a cylindrical capacitor as an example of the ladder-shaped electronic component series 2. In FIG. 4 is an element part of a capacitor, and a plurality of element parts 4 are connected to 2
They are connected in a ladder shape by book leads 6. The ladder-shaped electronic component string 2 is generally stored wound around a drum or the like, so when feeding it to an automatic insertion machine, in order to remove any curls, the electronic component string pulled out from the drum 8 as shown in Fig. 2 is used. 2 is sent to a cutter section (not shown) of an automatic insertion machine via a plurality of rotating reels 10, and the cutter section cuts the capacitors into individual capacitors, which are then mounted on a printed circuit board or the like. Although not shown, the drum 8 is provided with a control device so that tension is applied to the lead 6 of the electronic component series 2 passing through the reel 10.

However, conventionally, as shown in Figure 3, reel 1
Since the circumferential surface 10a of the reed 6 was simply cylindrical, the reed 6 after passing through the reel 10 still retains the curvature from when it was formed into a ladder shape. For this reason, the two leads 6 of the capacitor after being separated one by one intersect as shown in FIG. 4, which often causes the inconvenience that the capacitor cannot be automatically inserted into a printed circuit board or the like.

The purpose of the present invention is to eliminate such conventional drawbacks, and the electronic component series 2 is connected to the reel 1.
In the process of passing 0, a slight outward bending force is applied to the two leads 6 to remove the inward bending of the leads 6, and an automatic machine inserts the leads into the mounting holes of the printed circuit board, etc. 6 can be inserted reliably.

Next, an embodiment of the present invention applied to the electronic component series shown in FIG. 1 and the supply device shown in FIG. 2 will be described with reference to the drawings.

The ladder-type electronic component supply device of the present invention is similar in basic structure to the conventional one, but has a distinctive feature in the shape of the reel 10.
The figure is a front cross-sectional view of the reel 10 of the present invention, and what makes this reel 10 different from conventional reels is the shape of its circumferential surface 10a. That is, the circumferential surface 10a of the reel 10 of the present invention has a groove 10b with a substantially V-shaped cross section formed therein. Therefore, when the electronic component train 2 passes through the reel 10, a part of the lead 6 falls into the groove 10b due to the tension acting on the lead 6, as shown in FIG.
The two leads 6 are given a bending force that spreads them outward. Figure 7 shows the state of the electronic component series 2 after it has passed through the reel 10. When the electronic component series 2 is separated into individual capacitors by a cutter, the two leads 6 of the capacitor are always in an open state without crossing. Therefore, as shown in Figure 8, the tapered holes 12a
By using the guide member 12 having the
The leads 6 of the capacitor can be reliably inserted into the mounting holes 14a of the printed circuit board 14 by an automated machine.

Note that the groove 10b does not necessarily fit all reels 10.
There is no need to provide one reel 10.
It is also possible to simply form the Furthermore, it goes without saying that the present invention can be applied not only to electronic components mounted on a printed circuit board, but also to electronic components mounted on the base of an intermediate frequency coil or the like.

Since the ladder-shaped electronic component chain supply device according to the present invention has the above-described configuration, according to the present invention, the bent leads can be easily corrected by simply passing the electronic component chain through the reel, and the leads of the electronic components can be easily straightened. This has the effect that it can be reliably inserted into the mounting hole of a printed circuit board or the like using an automatic insertion machine.
