It is advanced to the discharge port where it is blocked by the first blocking device. In this state, the mating member is inserted into the ring-shaped part at the tip through the U-shaped notch and fitted. Thereafter, when the operating member is operated to move the first and second blocking devices to the second position, the components behind the ring-shaped component at the tip are prevented from advancing by the second blocking device, and the mating member is inserted. Since the U-shaped notch is open toward the discharge port, the ring-shaped part at the tip can be released while being fitted into the mating member. Then, by returning the first and second blocking devices to the first position using the operating member, the next ring-shaped component can be supplied and inserted.

【Example】

An embodiment of this invention will be described below with reference to the drawings. In the embodiment described here, the small circular component is a ring solder. First, a first example will be described. Figure 1 shows
FIG. 2 is an exploded perspective view showing the first to third embodiments of this invention, and FIG. 2 is an enlarged cross-sectional view of the tip of the first embodiment. Shown after parts are released. In Fig. 1, this supply/insertion tool can be roughly divided into a hopper 2 for storing the ring solder 10, a groove 3 for aligning and feeding the ring solder 10, and a mechanism for discharging the ring solder 10 one by one. There is. The hopper 2 is a space located at the right end of the main body 1 in which a large number of ring solders 10 are stored. At the left end of the hopper 2, there is a funnel-shaped discharge port 2a. A shallow U-shaped groove 3 is connected to the discharge port 2a, and the ring solder 10 is fed in a line inside the groove 3. The other end of the groove 3 is open to form a discharge port 4. This outlet 4
can take various forms, as explained below. Now, the members for discharging the ring solder 10 one by one from the discharge port 4 are the first and second stoppers 5 and 6 and the operating fitting 7. 1st, 2nd
The stoppers 5 and 6 are made of spring plates, and each tip is bent at a nearly right angle, and the other end is bent to the main body 1.
are fixed opposite each other on the sides of the Note that the tips thereof have an interval corresponding to the diameter of the ring solder 10, and the first stopper 5 is located in the front. The operation fitting 7 has an operation button 7a as described below.
A shaft with a partially tapered base is connected to the shaft. The second stopper 6 is fitted into the tapered base portion of the operating fitting 7, and the shaft portion is loosely inserted into the hole drilled in the main body 1. Its end is prevented from coming out by a first stopper 5. A fixed lid 8A is fixed to the top surface of the main body 1 with unmarked screws, and a movable lid 8B has its left end fitted into the right end of the fixed lid 8A, and can be attached and removed using a stopper 9 at its right end. possible to be suppressed.
The fixed lid 8A and the movable lid 8B can be made of transparent material. Note that the content explained above is common to the first to third embodiments. In FIG. 2, the main body 1 and the groove 3 in the first embodiment
The configuration of the tip, the first and second stoppers 5 and 6, and the operating fitting 7 will be described in more detail. The tip 5a of the first stopper 5 can stop the tip of the main body 1 and the tip of the groove 3, and the intermediate portion 5b is in contact with the shaft end of the operating fitting 7. Further, a stopper 1a is penetrated and opened at the tip of the main body 1, and the bent tip 6a of the second stopper 6 is fitted into this. Also, the second stopper 6
The intermediate portion 6b is fitted into the neck at the base of the operation button 7a of the operation fitting 7. A U-shaped notch 3b is provided at the bottom of the tip of the groove 3 with the opening thereof on the left side.
Since the configuration is as described above, the operation of the first embodiment is as follows. (1) A large number of ring solders 10 are stored in the hopper 2 (see Figure 1), and (2) when fine vibrations are applied to the hopper 2, the ring solders 10 are placed in grooves one by one from the outlet 2a of the hopper 2. I am guided by 3. (3) The ring solder 10, which is aligned in a line and advances in the groove 3, is stopped from advancing at the tip 5a of the first stopper 5, which closes the other opening of the groove 3. (See Figure 2a). (4) In this state, insert the tip of the groove 3 into a predetermined location of the mating member where the ring solder 10 is to be supplied and inserted - for example, the upper outer periphery of the glass terminal 52 (the eighth
(see figure) - and use the terminal bar of the glass terminal 52 to cut the U-shaped notch 3b and the ring solder 10.
pass through the center hole. (5) Press the operating button 7a of the operating metal fitting 7, push down the intermediate portion 5b of the first stopper 5 with the tip of its shaft, lower the tip 5a, and open the opening of the groove 3. In this state, when the main body 1 is pulled to the right, the ring solder 10 is released from the opening of the groove 3 and placed at a predetermined location, for example, on the outer peripheral surface of the glass terminal 52.
It is supplied and inserted in a loose fit. At this time, since the tip 6a of the second stopper 6 is in a position to close the groove 3, the next ring solder 10 is blocked and will not be ejected. (6) When the operation button 7a of the operation fitting 7 is released, the first stopper 5 returns to the position where it closes the opening of the groove 3 due to its elasticity (the second
At the same time, the second stopper 6 also returns to its original position due to its elasticity, opening the groove 3. Then, the next ring solder 10 moves forward until it reaches a position where it can be released, and is stopped by the tip 5a of the first stopper 5. (7) By returning to the above-mentioned item 4 and repeating the same procedure, it is possible to supply and insert the ring solder 10 one after another. In addition, in the center recess of the cap 51 in FIG.
When dropping the ring solder 20, it is sufficient to discharge it from the left opening of the groove 3 while vibrating the main body 1 finely as described in item 5 above (see FIG. 2b).
Of course, in this case the U-shaped notch 3b is not functioning. In this first embodiment, when the ring solder 10 is carried to a predetermined location, that is, when it is in the state shown in FIG. There is no risk of it falling off even if it receives a shock. Next, a second embodiment will be described with reference to FIG. 3. FIG. 3 is an enlarged cross-sectional view of the tip of this embodiment, and the figure a shows the part just before it is released;
Figure b shows the part after it has been released. This embodiment is different from the first embodiment described above in that the upper half of the tip of the main body 11 is cut out. The left part is missing. By doing this, when inserting the ring solder 10 around the outer circumference of the glass terminal 52 in FIG. 8a, there is no difference from the first embodiment, but when inserting the ring solder 20 into the central recess of the cap 51, It can be emitted from the left tip of the main body 1 to the left or upward, so it is possible to choose a direction in which it is easy to apply fine vibrations. This is a great advantage in practice because the ring solder 20 is small and light. A third embodiment will be described with reference to the enlarged cross-sectional view of the distal end of FIG. 4. Note that the states shown in a and b in the same figure are the same as those in the case of FIGS. 2 and 3 already described. In this embodiment, the tip end and groove bottom 13a of the groove 13 of the second embodiment are removed to form the groove 23, and the tip end 5 of the first stopper 5 of the second embodiment is replaced.
This embodiment differs from the second embodiment in that a rectangular bottom plate is provided at the corner of a and serves as a first stopper 25. In addition, 2
5a is the tip of the first stopper 25, and 25c is a rectangular receiving plate provided at the corner of this tip 25a. The function of this third embodiment is different from that of the previous ones by pushing down the operation fitting 7 to pull the receiving plate 25c.
The ring solder 10 can be discharged. That is, there is no need to apply fine vibrations to the main body 21. In this third embodiment, the receiving plate 25c may be provided with a U-shaped hollow portion opening at its upper side. By doing this, ring solder 1
0 can also be inserted into the glass terminal 52 of FIG. Next, a fourth embodiment will be described with reference to the exploded perspective view of FIG. 5. In this embodiment, the main body 3
1. The fixed lid 38A and the movable lid 38B are curved as shown in the figure. Related members also have slightly different shapes in this regard, but detailed explanations will be omitted. According to the fourth embodiment, even if the location where the ring solder 10 is to be supplied and inserted is located at a deep location, the tip of the tool can be placed in a position that makes it easy to supply and insert the ring solder 10. This will be specifically explained with reference to FIG. This figure shows the glass terminal 52 of the assembly unit 50 of FIG.
The relative positional relationship when inserting the ring solder 10 using the fourth embodiment is shown. Dot-dashed line B
is the center line of the main body 31 (see FIG. 5) of the fourth embodiment when viewed from the side, and the tip thereof is the glass terminal 52.
almost perpendicular to the axis of A comparison with the first to third embodiments can be seen in FIG. That is, the dashed dotted line A in FIG. 6 is the center line of the main body 1, 11, 21 of the first to third embodiments when viewed from the side, and it is clear that the tip thereof is aligned with the line perpendicular to the axis of the glass terminal 52. It is sloping. This is ring solder 10
This means that it is difficult to insert. Main body 1, 1
