DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring-shaped solder suitable for welding internal components such as a portable telephone, and more particularly, to a thread solder with a built-in flux core from a thread solder supply source. It is continuously supplied to the ring forming mechanism to form a circular shape, the circular solder is supplied to the cutter mechanism at regular intervals, and at the same time, one turn of the circular solder is cut off, and the separated deformed ring is sent to the sorting mechanism. The present invention relates to an automatic ring-shaped solder manufacturing method and a manufacturing apparatus for supplying a non-defective and non-defective deformed ring to a ring shaping unit for correction and shaping.

[0002]

2. Description of the Related Art In the case of manufacturing a ring-shaped solder having a diameter of, for example, about 5 mm from a thread solder having a built-in flux core, conventionally, for example, a thread solder fed from a thread solder supply mechanism is used to remove the peripheral surface of a circular shaping roller. A semi-arc shaped shaping die which is supplied above and arranged on the circumferential surface of the shaping roller is continuously stamped on the shaping roller circumferential surface, and a circle shaped along the circumferential surface of the shaping roller. The ring-shaped solder was shaped by cutting the shaped rings one by one. Further, as another conventional manufacturing method, a solder having a built-in flux core of this type is formed into a sheet having an appropriate size, and a ring-shaped punching die is used from the sheet solder.
Ring solder was punched out and shaped one by one.

[0003]

However, in the case of the manufacturing method using a shaping roller and a shaping die, the thread solder itself is extremely fine, and therefore, when stamping, the thread solder changes from a solid round shape to a flat shape. Not only is it crushed and deformed, but it also takes a considerable amount of time to shape one ring-shaped solder because it transfers and shapes the yarn solder along the circumference of the shaping roller while stamping. From what you need,
It lacked mass productivity. In particular, if the diameter of the ring-shaped solder is 3
When the diameter is as small as mm or less, it was almost impossible to shape the ring-shaped solder by the manufacturing method by stamping.

In a method of manufacturing from a sheet solder by using a punching die, first, a solder having a built-in flux core must be formed into a sheet of an appropriate size, or a ring is punched from a sheet material by a punching die. In this case, material loss occurs and it is not economically favorable,
Moreover, since the flux core is exposed on the entire peripheral surface of the ring-shaped punched circular solder, there is a problem in long-term storage due to oxidation due to contact with the atmosphere.

The inventor of the present invention has made an effort to improve the above-mentioned manufacturing method and realize the manufacturing by fully automatic operation. We have succeeded in developing a completely new production method and a production apparatus for the same, which can be stored for a long period of time with minimum prevention.

An object of the present invention is to provide a ring-shaped solder automatic manufacturing method and an apparatus for manufacturing the same, which can perform a proper cutting.

[0010] Still another object of the present invention is to provide an automatic polishing of the cutting edge by rotating a circular cutter so that a contact-type abrasive is detachably contacted with the cutting edge which separates the circular solder one turn at a time.

The deformed ring 40a cut and cut by the circular cutter 39 is put into the entrance 117 of the chute 116 from the tip 37a of the winding shaft 37. The deformed ring that has passed through the chute 116 is dropped onto the rotating turntable 126 from the outlet thereof. In this case, the turntable 126 is rotated at a constant speed by the pulley 152 being rotated from the pulley 155 of the motor 154 via the belt 153 and the turntable shaft 150 being rotated thereby.

Further, in this case, the turntable 1
Since the ring 26 is a circular movement, the deformed ring dropped on the surface of the turntable 126 is transported while being acted on in the circumferential direction, and is supplied to the sorting mechanism 125 in cooperation with the guide edge 129. Since the sorting element 132 is arranged on the surface of the turntable 126 so as to protrude from the circumferential direction to the center direction, the sorting element 132 sorts various deformed rings carried on the turntable 126 and transferred. The selection gap 135 allows only the non-defective deformation ring 127 to pass, and the defective deformation ring 128 in which several pieces are overlapped cannot pass through the selection gap 135, and the defective deformation ring 128 is discharged from the shaping line.

The non-defective ring 127 passing through the sorting gap 125 is guided under the rotating shaping roller 140. That is, the rotation of the turntable shaft 150 causes the bevel gear 1 to rotate.
The shaping roller shaft 158 is rotated via 56 and 157,
The shaping roller 140 is rotated on the surface of the turntable 126. The shaping roller 140 is rotated at a predetermined distance from the surface of the turntable 126, and therefore, the opening 127 of the non-defective deformation ring 127 is rotated by the shaping roller surface 159.
b is corrected under pressure, the ring-shaped solder 127a is corrected and shaped, and the ring-shaped solder as a final product is automatically shaped.

As described above, the thread solder is continuously formed into a circular solder, the circular solder is supplied to the cutter at regular intervals, and each turn of the circular solder is cut off. A series of steps of selecting only non-defective deformed rings having predetermined dimensions from among deformed rings having an opening and correcting and shaping the selected non-defective deformed rings into a ring shape can be performed by fully automatic operation. Solder can be manufactured very efficiently and mass-produced.
