Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to ring solder manufacturing for manufacturing a ring solder, which is used when fitting a part to a stud or the like standing upright from a work and firmly fixing the part to the stud. Regarding the machine.

[0002]

2. Description of the Related Art Recently, when a desired component is mounted on a work, the soldering work is often used because the mounting of the component becomes easy if a large force does not act on the component. In particular, a ring solder that is inserted through the stud is used when fitting the component to a stud or the like that stands upright from the work and firmly fixing the component to the stud.

[0003]

However, since this ring solder has to be formed into a ring shape at the time of manufacturing the solder, there are disadvantages such that the manufacturing is troublesome and the cost of the ring solder is high, and the cost is low. There is a demand for an apparatus for easily producing ring solder from wire solder.

The present invention has been invented in view of the above demands, and an object thereof is to provide a ring solder manufacturing machine capable of manufacturing ring solder from winding solder.

[0005]

A winding shaft for winding the winding solder for one rotation and stopping the rotation is horizontally slidably arranged in a feed allowance adjusting ring. Further, there are provided a cutter that can move forward and backward in a direction intersecting with the winding shaft, and a reciprocating drive unit that moves the cutter forward and backward every one rotation of the winding shaft. Further, there is provided a forward / backward means for moving the cutter forward and backward to return the winding shaft to the original position by reciprocating the winding shaft by the diameter of the winding solder, and after cutting the winding solder by the cutter, the winding solder is wound. The take-up shaft is retracted to drop the cut solder from the take-up shaft.

[0006]

In this ring solder manufacturing machine, the winding solder is closely wound around the winding shaft leaving a space for one winding, and when the winding shaft is rotated once from this state, the winding solder is It is wound up once. After the winding shaft is stopped, the reciprocating driving means is operated, the cutter advances toward the winding solder, and the winding solder cuts only the first winding. Thereafter, when the cutter retracts, the advancing / retreating means of the winding shaft operates, and the winding shaft retracts with respect to the feed allowance adjusting ring by the diameter of the winding solder. Therefore, the solder wound around the take-up shaft is relatively pushed out from the take-up shaft, and one roll of the ring solder cut and held at the tip of the take-up shaft falls to produce ring solder. After that, the advancing / retreating means moves back to advance the winding shaft and return the winding shaft to the original position.At this time, the winding shaft moves forward together with the solder wound on the winding shaft and is wound around the winding shaft. Leave a space for one roll of wire solder and prepare for the next work.

In the ring soldering machine, the winding shaft 4 is
Then, the winding solder 6 is closely wound after leaving one rotation, and the motor is rotated from this state to rotate the first output shaft 23a and the second output shaft 23b of the rotation indexing unit 23, respectively. The rotation of the first output shaft 23a is transmitted to the first driven pulley 7 via the I-th drive pulley 24 and the first timing belt 25, and the winding shaft 4 makes one rotation integrally therewith and stops for a while. With one rotation of the winding shaft 4, the winding solder 6 is wound around the winding shaft 4 for one rotation. At the same time, the second output shaft 23b
Is rotated by the second drive pulley 27 and the second driven pulley 29.

Therefore, the cam shaft 18 rotates, and the arm cam 15 and the lever cam 1
1 rotates together. When the arm cam 15 starts to rotate, the cam follower 14a attached to the arm 14 follows an arcuate surface until the winding shaft 4 stops, and the arm 14 is kept in a constant posture. When the winding shaft 4 is stopped, as shown in FIG. 5, the cam follower 14a follows the gently rising surface of the arm cam 15, and the arm 14 rotates on a horizontal plane. By this rotation of the arm 14, the cutter shaft 13 is guided by the linear bush 12a and advances toward the winding solder 6 wound on the winding shaft 4, and the cutter 13a at the tip thereof is wound as shown in FIG. The wire solder 6 is cut only at the first winding.

Return from 4 to the original position.

At the same time when the arm cam 15 rotates, the lever cam 11 rotates integrally, but until the cam follower 14a of the arm 14 reaches the arc surface of the arm cam 15, the cam follower attached to the lever 9 is attached. 9a follows the arc surface. Therefore, the posture of the lever 9 is kept constant during that time, but when the cam follower 14a of the arm 14 reaches the arc surface of the arm cam 15 as shown in FIG. 6, the cam follower 9a of the lever 9 moves to the lever cam 11. The lever 9 rotates along the mounting plate 3 on a horizontal plane following the sharp convex surface.

The winding shaft 4 integral with this is guided by the thrust bearing 3a and retracts by a distance corresponding to the diameter of the winding solder 6. Therefore, the winding shaft 4 retracts with respect to the feed allowance adjusting ring 5 by the diameter of the winding solder 6, and the winding solder 6 wound around the winding shaft 4 is relatively pushed out from the winding shaft 4. At this time, the ring solder 6a for one rotation cut and held at the tip of the winding shaft 4 drops, and the ring solder 6a is manufactured. After that, the cam follower 9 of the lever 9
As soon as a goes over the convex surface of the lever cam 11, it reaches the circular arc surface and the lever 9 returns, and at the same time, the first driven pulley 7 and the winding shaft 4 also return to the original position. Moreover, at this time, the remaining winding solder 6 wound around the winding shaft 4
Moves forward integrally with the winding shaft 4, and a space for one rotation is formed between the winding allowance adjusting ring 5 and the winding solder 6 around the winding shaft 4, so that it can be prepared for the next work. ..

Further, the ring solder 6a dropped from the winding shaft 4 is sent between the pressing rollers 31 and the ends thereof are pressed by the pressing rollers 31 to form a ring solder 6a having a perfect shape. , Is discharged from the discharge chute 37 and is stored in a component storage box (not shown).

Although the winding shaft has a hexagonal cross section in the embodiment, it may have another polygonal shape or an elliptical shape.

[0019]

As described above, according to the present invention, one end of the winding solder is wound on the winding shaft and cut for each winding, and the winding shaft after cutting is formed by the diameter of the winding solder. The winding solder that is retracted and cut and held at the tip of the winding shaft is dropped, and after winding solder is cut, the winding shaft is returned to the original position together with the remaining winding solder, and the next winding is wound. Since it is configured to secure a space for wire solder, there are advantages such that ring solder can be easily and continuously manufactured from wound wire solder, and a machine for manufacturing inexpensive ring solder can be provided. ..
