Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called electronic component chain (taping electronic component) in which lead wires of small electronic components such as ceramic capacitors are fixed to a band-shaped holder at a constant pitch.

Fig. 1 shows a conventional electric component series, in which 1 is a band-shaped holder made of cardboard and adhesive tape;
Reference numeral 2 denotes an electronic component equipped with a radial lead wire, which in the illustrated case is a ceramic capacitor.

Reference numeral 3 denotes lead wires, and by holding the lead wires 3 on the band-shaped holder 1, a large number of electronic components are fixed at regular intervals.

Reference numeral 5 denotes feed holes, and the holes 5 are provided in a line at the same pitch as the electronic components 2 at approximately the center of the band-shaped holder 1.

The conventional electronic component series has the above-mentioned configuration, and the feed hole 5 is used in all processes, that is, on the manufacturing equipment side, on the user side, that is, the side that manufactures the electronic components themselves, and on the electronic circuit using electronic components. on both sides, each used by an automatic machine.

That is, on the manufacturing equipment side, a sprocket or positioning pin for automatic feeding to an automatic measuring machine for the manufacturing process or the shape of the electronic component 2 is engaged with the feed hole 5 to perform automatic feeding.

On the user side, a sprocket or the like of an automatic insertion machine that automatically inserts the lead wire of the electronic component 2 into the lead wire insertion hole of the printed circuit board is engaged with the feed hole 5 to perform automatic feeding.

In this way, in conventional electronic component series, the same feed hole is used many times on both the manufacturing equipment side and the user side, so the feed hole 5 and the teeth of the sprocket and the positioning pin are engaged and disengaged many times. become.

Therefore, the feed hole 5 is severely worn, causing an error in the feed pitch of the electronic component series in an automatic insertion machine that requires high precision, resulting in problems such as the inability to accurately insert the lead wire 3.

This invention was made in order to solve the above-mentioned problems associated with conventional electronic components. A highly accurate feed pitch can be achieved by providing a feed hole row with a diameter larger than that of the staggered hole row in the center of the belt-shaped holder used in the stage of configuring the electronic circuit. The object of the present invention is to provide a series of electronic components for automatic insertion into a printed circuit board.

Hereinafter, an embodiment of an electronic component series of the present invention will be described based on FIG. 2.

In the drawings, the same parts as those in the electronic parts series shown in FIG.

In the case of this invention, in addition to the conventional feed holes 5, feed holes 6 with a slightly smaller diameter than the feed holes 5 are provided on both sides of the belt-shaped holder 1 at the same pitch as the feed holes 5, and the upper and lower feed holes 6 are staggered. Provided so that the arrangement is as follows.

At this time, make sure to avoid the lead wire 3 through the feed hole 6.
Needless to say, it is necessary to provide

In the case of the above-mentioned embodiment, for example, on the manufacturing equipment side, sprocket teeth or positioning pins are engaged with the staggered feed holes 6 to perform various operations such as measurements.

After that, this electronic component chain is packaged and transported to the user's side, and when the electronic component chain is used at the user's side, the central feed hole 5 is inserted into the sprocket teeth or positioning pin of an automatic love insertion machine. When engaged, the electronic component 2 is automatically inserted into a printed circuit board or the like.

In this invention, as in the above embodiment,
Multiple rows of feed holes are provided, including feed holes used in the manufacturing stage of electronic components and feed holes used in the stage of configuring electronic circuits, and these are arranged in a staggered manner on both sides of a belt-shaped holder used in manufacturing equipment, etc. arranged perforations,
By separately using a row of perforations with a larger diameter than the staggered perforations in the center of the belt-shaped holder used by the user, the user can use the existing equipment as is. Moreover, it is possible to send a series of electronic components with a high precision pitch using a new, unused feed hole.

Therefore, it can be used satisfactorily even in cases where extremely high precision is required, such as in a device that automatically inserts lead wires of electronic components into lead wire insertion holes of printed circuit boards.

In addition, in this invention, the reason why the feed holes 6 are arranged in a staggered manner is to disperse the many stresses that are applied during long-time transportation during the manufacturing stage, and to eliminate lateral deviation during automatic feeding and positioning. This is to improve accuracy.

Although the feeding holes 5 and 6 are round holes in the illustrated example, they may have various shapes such as elongated round holes, square holes, polygonal holes, etc. depending on the purpose.
