Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for transporting a coil bobbin in a small coil part during the manufacturing process of a small coil part having a terminal plate having a plurality of terminal pins embedded therein.

Conventionally, small coil parts, such as high-frequency coils, include a cylindrical coil bobbin having a terminal portion with a plurality of terminal pins implanted in one collar, and a high-frequency magnetic core is threaded onto this coil bobbin, and the coil is wound around the coil bobbin. It is composed of:

In such a small coil component, the coil bobbin 1 before winding the coil is separated by a partition plate 2 (see FIG. 1).
The parts were stored in a parts box 3 partitioned into a room and transported to the winding process, where they were taken out one by one and set in a winding machine, and after winding, they were stored in separate packaging boxes.

This method has poor productivity and
Because it is done manually, external force is applied to the terminal pins when putting them in and taking them out of the parts box, making it impossible to attach them to the winding machine, resulting in poor yields and a significant cost disadvantage. It was something.

The present invention eliminates the drawbacks of the prior art as described above.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings of FIGS. 2 and 3.

First of all, in FIG. 2, 4 is a turntable, and this turntable 4 includes a terminal part 6 formed by implanting three or more terminal pins 5 in one collar, and a bobbin around which a coil is wound. A plurality of holders 8 that hold the coil bobbin 9 consisting of the section 7 are provided at equal intervals, and during this rotating process, the high frequency magnetic core is screwed into the coil bobbin 9.

Of course, some small coil parts do not require a high frequency magnetic core, and in this case, the turntable 4 is used only for attachment to a tape, which will be described later.

Further, at a certain position of the turntable 4, the extrusion rod 10 operates to extrude the coil bobbin 9 held by the holder 8.

In other words, at the position where the coil 9 is pushed out,
A conveyor tape 11 made of synthetic resin or the like is arranged.

This conveyance tape 11 is pulled out from a tape reel 12, and is wound around a winding drum 16 via a tape guide 13.

In the same way as the tape reel 12 and the tape guide 13 of the conveying tape 11, a component insertion jig is installed at the corresponding position of the coil bobbin 9 with the same number of pins 14 as the terminal pins 5 of the coil bobbin 9. 15 are arranged.

That is, the conveying tape 11 is hooked on the three pins 14 of the component insertion jig 15 and is bent into a U-shape.

In this state, the terminal pin 5 is placed on the carrier tape 11.
When the coil bobbin 9 held by the holder 8 of the turntable 4 is pushed out in the direction of the arrow with the pushing rod 10,
The three terminal pins 5 arranged in a straight line are connected to the conveyor tape 1.
1.

In this engagement, for example, the terminal pins 5 at both ends are connected to the carrier tape 1.
10 If it is on the front side, the one in the center will be on the back side.

In addition, in synchronization with the engagement of the terminal pin 5 with the transport tape 11, the component insertion jig 15 also moves in the same direction as the push rod 10, and the dowel pin 14 moves onto the transport tape 11. Move it just before it comes off the edge.

In this state, the conveying tape 11 is wound onto the one-pitch winding drum 16 side.

When the transport tape 11 advances one pitch in this way, the component insertion jig 15 moves in the direction opposite to the direction of the arrow in FIG. 2 to completely engage the transport tape 11 with the terminal pin 5 of the coil bobbin 9. Curve it into any shape you can.

By repeating these 6 operations, the transport tape 11
The coil bobbin 9 can be sequentially assembled into the coil bobbin 9.

In this embodiment, it has been described that the conveying tape 11 engaged with the coil bobbin 9 is wound onto the winding drum 16, but the coil bobbin 9 is automatically or manually fed in this state until the winding process. It may also be taken out from the carrier tape 11 and mounted on a winding machine.

The use of the winding drum 16 as described above is effective when the winding process is performed at completely different locations.

Further, in the above embodiment, the case where the product is used as a semi-finished product has been described, but after finishing the winding, the finished product is covered with a case and is assembled into this conveying tape 11, and various electronic parts are mounted on the printed circuit board. It may also be used to transport the product to the assembly process where it is incorporated.

As described above, according to the method for conveying a coil bobbin in a small coil component of the present invention, automation is possible, and assembly and removal can be performed easily and reliably, speeding up the work, and significantly improving productivity. In addition to this, there is no risk of deforming the terminal pins, quality can be guaranteed, and the device can be extremely simple and inexpensive, making it a dog of industrial value. .
