[0002]

2. Description of the Related Art A part in which lead pins are led out in parallel from a radial-shaped part body, such as a coil with a lead pin, is called a so-called radial part. For example, in the case of a core with lead pins for winding the coil, the core of the component body has a drum shape or a cylindrical shape, and a pair of lead pins are led out in parallel to one end face thereof.

Conventionally, when a lead pin is fitted into a component body to manufacture a radial component, as shown in FIG. 8, an upper portion of a first support portion 4 arranged on the rear side of the lead insertion jig 2 is placed. The bobbin 1 of the coil, which is the component body, is dropped into the plurality of large V-shaped grooves 3, 3, ... Next, the second support portions 6 arranged in two stages on the front side of the lead insertion jig 2,
The lead pins 5 and 5 to be inserted are dropped into the plurality of small V-shaped grooves 7, 7, which are also continuous and formed on the substrate 6, and are arranged at predetermined positions. At this time, an adhesive is applied in advance to the tip portions of the lead pins 5, 5 to be inserted and fixed. After that, while pressing the bobbin 1 from the rear,
The lead pins 5 and 5 are pushed and inserted into the pair of holes 8 formed in the end surface of the bobbin 1.

[0004]

However, in the above-described lead pin insertion jig and insertion method according to the prior art, the bobbin arrangement and alignment, the lead pin arrangement, and the lead pin insertion work are not automated. , Therefore, the productivity of such radial parts was low. Therefore, in view of the above problems in the conventional technique, it is an object of the present invention to provide a lead component mounting device for a radial component that can automatically perform a lead component insertion operation for a radial component.

[0005]

Lead pin arranging portions, and an adhesive applying means for applying an adhesive to the tips of the lead pins arranged in the lead pin arranging portions,
Arranged adjacent to the conveyor section, the lead pin insertion section for pressing the lead pin and the component body on the conveyor from both sides to insert the lead pin into the hole formed in the end face of the component body, and the component body. A lead pin mounting device for a radial component, comprising: an adhesive curing furnace for curing an adhesive of the inserted lead pin.

[0006]

According to the present invention described above, the component body and the lead pin are arranged on the conveyer portion so as to face each other by the component body arranging portion and the lead pin arranging portion, and the adhesive is applied to the tip of the lead pin. . In this state, the lead pin and the component body are pressed from both sides by the lead pin insertion portion, so that the lead pin is inserted into the hole on the end face of the component body. Then, the adhesive is heated and cured in the adhesive curing furnace. Therefore, the work of inserting the lead pin of the radial component can be automatically performed.
