Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a bar-shaped article insertion device for efficiently inserting a plurality of bar-shaped articles having different diameters at the top and bottom into a receiver such as a sealing jig.

For example, when manufacturing an airtight terminal in which lead wires are hermetically and insulated sealed inside a metal outer ring through glass, the lead wires are inserted into the grooves provided in the sealing jig, and each lead wire is covered with glass. The tablet and the metal outer ring are inserted in sequence, and the glass tablet is sealed by heating and melting it.

However, the groove of the sealing jig! J-)" Inserting the wire takes a lot of time, especially if the lead wire is nail-shaped or the pipe tip is flared, and the top and bottom have different diameters, so the insertion work must be done quickly. I couldn't do it.

The present invention was proposed in view of the above points, and is designed to allow a large number of rod-shaped articles having different diameters at the top and bottom to be inserted into a receptacle for a sealing jig or the like at once.

An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 to 5, 1 has through holes 2 for accommodating several nail-shaped lead wires a as an example of a rod-shaped article at predetermined intervals. A plurality of substrates are provided, and a guide frame 3 for positioning is provided on the outer periphery of the substrate. 4 corresponds to each through hole 2 of the substrate 1 and is an example of an insertion portion into which only the small diameter portion of the lead wire a can be inserted. A first auxiliary plate 6 is provided with insertion holes 5 of the auxiliary plate 4, and has an insertion groove I into which a glass tablet b can be inserted, and a lead connected to the insertion groove T, corresponding to each insertion hole 5 of the auxiliary plate 4. A second auxiliary plate 10 is provided with an insertion groove 8 into which the large diameter portion of the wire a can be inserted, and a guide frame 9 is provided on the outer periphery of the second auxiliary plate, and 10 is a sealing jig as an example of a receiver for the lead wire a. , Corresponding to each insertion groove 8 of the auxiliary plate 6, an insertion groove 11 into which only the small diameter portion of the lead wire a can be inserted is provided.

Now, the substrate 1 and the first auxiliary plate 4 are placed one on top of the other via the guide frame 3, a large number of lead wires a are placed on the top surface of the substrate 1, and vibrations are applied to the lead wires a by an appropriate means. As shown in FIG. One small diameter part with the head a' facing up is the first
is inserted into each insertion hole 5 of the auxiliary plate 4.

Next, with the board 1 and the first auxiliary board 4 stacked on each other, the board 1 and the first auxiliary board 4 are rotated 90 times in a vertical plane to remove the auxiliary board 4 from the board 1, and then the second auxiliary board 6 is moved around its guide frame 9. By superimposing it on the first auxiliary plate 4 through the auxiliary plate 4 and rotating it by 90 degrees in the same direction, the lead wires a inserted into the respective insertion holes 5 of the first auxiliary plate 4 will be aligned as shown in FIG. Then, it is inserted into each insertion groove 8 of the second auxiliary plate 6 with the large diameter portion a' facing down.

Next, the first auxiliary plate 4 is removed, a large number of glass tablets b are placed on the upper surface of the second auxiliary plate 6, and vibrations are applied to them by an appropriate means, as shown in FIG. 3. Then, a glass tablet b is inserted into each insertion groove 7.

Next, the sealing jig 10 is stacked downwardly on the upper surface of the second auxiliary plate 6 via the guide frame 9, and then rotated 180 degrees in a vertical plane. The lead wire a inserted into the insertion groove 8 falls and is inserted into each insertion groove 11 of the sealing jig 10, as shown in FIG.

Next, remove the second auxiliary plate 6, and insert the metal outer ring C, which has been inserted into the insertion groove of the third auxiliary plate (not shown), into each glass tablet b of the sealing jig 10. For example, as shown in FIG. 5, lead wires a are placed on the sealing jig 10 at predetermined intervals.
, the glass tablet b, and the metal outer ring C are assembled into a plurality of assemblies.

When the assembly thus obtained is placed in a heating furnace, the glass tablet b is melted and an airtight terminal is obtained.

In the above embodiment, the first auxiliary plate 4 may have a non-penetrating insertion groove instead of the insertion hole 5, as shown by the two-dot chain line in the figure.

Furthermore, when overlapping the substrate 1 and the first auxiliary plate 4, as shown in FIG. and
If the two first auxiliary plates 4゜4' are used alternately from now on, not only will the trouble of placing a large number of lead wires a on the board 1 each time be eliminated, but also each Among the plurality of lead wires a accommodated in the through hole 2, those with the heads a' facing down can be used efficiently.

Furthermore, in the above embodiment, the second auxiliary plate 6 has glass taps.
The insertion groove 7 for the glass tablet b is provided so that the glass tablet b can be inserted through the lead wire a when the lead wire a is inserted. If there is no groove for positioning the sealing jig 10,
It is difficult to place the glass tablet B or the like in a predetermined position and insert the lead wire later, so it is more convenient to do as described above.

However, if a sealing jig 10 having grooves 12 for positioning the glass tablet b or metal outer ring C is used as shown in FIG.
Since a glass tablet B or a metal outer ring C can be inserted inside, a glass tablet (as shown in Fig. 8) can be inserted.
The second auxiliary plate 6 without the insertion groove 7 of b can be used.

Further, in the above embodiment, the nail-shaped lead wire is inserted into the sealing jig of the airtight terminal, but the present invention is not limited to this, and the lead wire may be shaped like a nail or have a flared tip. As long as it is possible to insert rod-shaped articles with different diameters at the top and bottom, it can be used for any purpose, not just inserting an airtight terminal into a sealing jig.

For example, as shown in FIG. 9, a lead wire e is fixed to one end of a metal case d, and inside the metal case d is a temperature-sensitive agent f made of a chemical substance that melts at a specific temperature, a strong compression spring g, and a movable contact h. , weak compression springs i are inserted one after another, and an insulating plug j, through which a lead wire a having a head a' that serves as a fixed contact is inserted through the center hole, is fixed to the open end of a metal case d, and the outer surface of the insulating plug j is In a temperature fuse coated with an insulating sealant K,
As shown in FIG. 10, the assembly jig 13 serving as a receiver can also be used to insert lead wires a into a large number of insulating plugs j.

Since the present invention has the above-described configuration, it is possible to insert a large number of rod-shaped articles with different diameters at the top and bottom into the receiver of a sealing jig, etc. at the same time, thereby significantly improving the efficiency of the insertion work. I can do it.
