Description

  The present invention relates to a mechanism of a device for supplying thread solder to a tip of a tip such as a rod-type soldering iron or a gun-type soldering iron which is generally used.

  Conventionally, in soldering operations with a soldering iron, thread solder is supplied by hand. Holding the thread solder with one hand and holding the trowel with the other hand, there is no problem in the soldering work, but there is a special contrivance in the work such as soldering unstable parts to the base and wiring installation. It was necessary.

  In that case, keep the parts fixed to the base by hand and supply solder with your hands, or fix the parts with some tools and perform the soldering work, etc. May take two steps.

  For this reason, a number of soldering irons for manually supplying thread solder have been proposed to eliminate the inconvenience. (For example, see Patent Document 1, Patent Document 2, and Patent Document 3)

JP 2004-130340 A Real fairness 06-027259 Japanese Utility Model 01-89868

  However, the soldering irons that have been considered to be used for manually supplying thread solder, the guides for guiding the solder, the position of the supply nozzle, etc. are all fixed to the iron, so sometimes they are out of the supply nozzle. There is a problem that the thread solder becomes a hindrance to work, and a general iron table cannot be used (because the guide and supply nozzle do not enter the tube of the iron table into which the tip is inserted).

  In addition, since the positional relationship between the solder feeder and the soldering iron is fixed, the solder feeder cannot be removed even when it is not necessary to manually supply the thread solder for a long time, and in terms of weight and usability, There may be situations where you need to use multiple trowels (one with or without a solder feeder).

  SUMMARY OF THE INVENTION An object of the present invention is to provide a mechanism of a manual thread solder supply device that eliminates the conventional problems.

  In order to solve the above problems, the following features are provided.

  According to the first aspect of the present invention, there is provided a yarn solder supply device that is attached to or used by a soldering iron, wherein the yarn solder supply device includes a mechanism that feeds the yarn solder and the fed yarn solder. A tubular member guided to the tip and an operating element, and the operating element is operated to rotate the tubular member about the predetermined axis with respect to the soldering iron, whereby the thread solder is moved from the tip. It is arranged to be retractable.

  According to a second aspect of the present invention, the yarn solder supply device according to the first aspect is detachable from a base integrally formed with the handle of the soldering iron or a base part attached to the handle of the soldering iron. It is attached to.

  According to the mechanism of the yarn solder supply device of the present invention, the soldering iron can be used for temporary attachment of parts by soldering or when the tip nozzle is close to the tip and there is no particular problem in operation. Thread solder can be supplied with one hand, so the other hand can support the parts.

  Also, if the tip nozzle is near the tip, soldering work in a narrow place where it hits or interferes with other parts, or when inserting the soldering iron into a general iron stand, In the case of cleaning, the tip nozzle can be temporarily retracted from the tip of the tip by operating an operator such as a lever, and these operations can be performed without any problem.

  Furthermore, when manual feeding is not necessary, it can be used as a general soldering iron by removing the thread soldering supply device from the soldering iron. Therefore, according to the present invention, one soldering iron can be used according to each work content. it can.

It is a side view of the whole thread | yarn solder supply apparatus containing a soldering iron. It is a top view of the thread | yarn solder supply apparatus in the state which supplies thread | yarn solder. It is AA sectional drawing of FIG. FIG. 7 is a cross-sectional view taken at the same position as in FIG. 6 in a state where the yarn solder is retracted from the soldering iron. It is the perspective view which showed the state which removed the thread | yarn solder supply apparatus from the soldering iron.

  Embodiments of the present invention will be described with reference to the drawings. However, although a rod-shaped soldering iron will be described as an example in the figure, the solder supply device of the present invention can be configured to be attachable to a gun-type soldering iron.

  As shown in FIG. 1, the base 11 is firmly fixed to the handle 9 of the soldering iron. The body mounting part 12 is attached to the base 11 by sliding the rail 12a of the body mounting part 12 into the groove 11a of the base 11 by sliding it from above. The base 11 and the main body attachment part 12 are structured to be detachable with high accuracy so that the position of the tip nozzle 3 is stabilized. After the main body attachment part 12 is mounted on the base 11, both of them can be pressed with screws, springs, etc. in order to prevent the main body attachment part 12 from moving relative to the base 11.

  A support pipe 14 is fixed to the main body attachment part 12 with a fastening bolt 22, and the angle adjustment part 15 is fixed to the support pipe 14 with a stopper bolt 20. A shaft 18 (see FIG. 2) for transmitting the rotation of the feed roller 13 to the gear 6 is rotatably passed through the support pipe 14.

  The support pipe 14 is passed through the solder supply unit frame 5. The solder supply unit frame 5 is sandwiched between the E-ring 17 (see FIG. 2) and the angle adjusting component 15 without play, and is configured to rotate with respect to the soldering iron handle 9 about the support pipe 14. That is, the position of the main body attachment part 12, the angle adjustment part 15, and the support pipe 14 is fixed with respect to the soldering iron, and the solder supply unit frame 5 slides and rotates with respect to the angle adjustment part 15 and the support pipe 14. The support pipe 14 is rotatable with respect to the soldering iron.

  The thread solder 2 passes through the hole of the solder supply unit frame 5 and is pressed against the gear 6 by coming into contact with the pressing bar 7 urged by the force of the pressing spring 8. Accordingly, the gear 6 is rotated by turning the feed roller 13 with the index finger of the hand having the handle of the soldering iron, and the yarn solder 2 is fed to the tip nozzle 3.

  FIG. 2 shows a state in which the solder supply unit 30 is disassembled in an easy-to-understand manner.

  As shown in FIG. 3, when the base 11 is not integrated as a part of the handle 9, the base 11 is fixed to the handle 9 with a fastening component 19 such as an insulok.

  As shown in FIG. 4, with the index finger of the hand holding the handle 9 of the soldering iron, the lever 10 is pulled rearward (near) of the handle 9, so that the solder supply unit 30 rotates around the support pipe 14. The tip nozzle 3 can be retracted from the tip 1. When the lever 10 is released, the original spring solder is returned to the tip with the force of the return spring 16 (see FIGS. 6 and 7).

  The plan view of FIG. 5 shows the cutting positions of the cross-sectional views shown in FIGS.

  FIG. 6 shows a state when supplying thread solder. The positioning bolt 21 attached to the solder supply unit frame 5 is pressed against the stopper bolt 20 of the angle adjusting component 15 fixed to the support pipe 14 by the force of the return spring 16. As a result, the solder supply unit frame 5 is stabilized at the position, and the tip nozzle 3 can supply the thread solder 2 to the tip 1.

  FIG. 7 shows a state when the tip nozzle 3 is retracted from the tip 1. By pulling the lever 10 with the finger in the direction of the arrow, the positioning bolt 21 of the solder supply unit 30 pushes the return spring 16 and the solder supply unit frame 5 rotates around the support pipe 14. By stopping the pulling of the lever 10, the solder supply unit frame 5 returns to the form shown in FIG.

  FIG. 8 shows a state where the solder supply device is removed from the soldering iron. By pulling up the main body attachment part 12 with respect to the base 11, the fitting between the groove 11a and the rail 12a is released, and the yarn solder supply device is removed from the soldering iron.

  In the above-described embodiment, the case where the yarn solder supply device is removable from the soldering iron has been described. However, the yarn solder supply device of the present invention is fixedly attached to the soldering iron in advance and cannot be removed. It can also be configured.
