Description

[0001] Apparatus For Soldering Shaped Like A Syringe [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soldering apparatus, and more particularly, to a scanning type soldering apparatus that enables accurate and convenient supply of solder to a soldering position in a scanning manner.

In general, soldering work requires soldering iron, lead solder, paste, and the like. The process of bringing the lead solder close to the soldering object and applying heat with the soldering iron to dissolve the lead solder and drop it on the soldering object is a soldering work process.

In educational settings such as academies, high schools, or universities, students actually practice soldering during practice sessions. In general, students are not professionally skilled and can not solder well. There are always the following difficulties for beginners. In other words, the lead and the pharynx are separated from each other and must be held with both hands, so it is difficult to drop an appropriate amount of lead in the correct position. In many cases, soldering is just a process of actually verifying the theory learned. However, due to the error of the solder, a circuit error such as a short circuit was caused, and in spite of being a simple experiment, a lot of time had to be wasted. Increasing proficiency in soldering work for simple theoretical verification can sometimes be seen as inefficient.

In some cases, it is also necessary to provide a means for simply repairing faults in electrical appliances caused by disconnection in a home. This is because it is wasteful to dispose of or to apply for A / S despite a simple malfunction.

2 is a sectional view of a scanning type soldering mechanism according to an embodiment of the present invention.
3 is a sectional view of a scanning type soldering apparatus according to another embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached hereto. First, one embodiment of the present invention will be described with reference to Figs.

The scanning type soldering apparatus of the present invention has a configuration similar to a general syringe. That is, the brazing mechanism includes a cylinder portion 10 and a piston portion 20 which is fitted in the cylinder portion 10 and performs a piston movement.

The cylinder portion 10 includes a cylinder 11 having an opening at the rear and a diaphragm 14 at the front. At the center of the diaphragm (14), an ejection hole (13) is provided. The cylinder portion 10 is basically made of a heat-resistant material and / or a heat-insulating material. The inner wall surface of the cylinder 11 may be provided with a smooth and heat-resistant material in lining form to facilitate the piston action. Sometimes, it can be smoothed by coating it as a heat resistant material. The outside of the cylinder of the cylinder part can be protected with a heat insulating material such as asbestos and gypsum, so that it is safe even if the heating part is held by hand.

The piston 20 is slidably inserted into the cylinder portion 10 and presses the material injected into the cylinder portion 10 in a direction to discharge the material through the spray hole 13. The piston portion 20 includes a piston body 23 closely fitted to the inner wall of the cylinder 11 of the cylinder portion and a rod 22 connected to the piston body 23 and a grip portion 21 provided at the end of the rod .

The heating means 30 is installed in the cylinder portion 10 so as to heat and liquefy the solder P injected into the cylinder portion 10 and to be sprayed through the spray hole 13. [ The heating means 30 is preferably a heating element. The solder (P) may be heated at a temperature suitable for use in practice, or at a temperature suitable for use in electrically connecting the disconnected parts in the home, though the melting point differs depending on the application or characteristics. The solder P can be charged by cutting the solder P to a proper length and putting it into the cylinder 11.

Hereinafter, the heating means 30 will be described. The heating means 30 includes a heating cylinder 32 fitted to the inner wall of the cylinder 11 of the cylinder portion in the same manner as the lining provided in the cylinder of the engine and a heating cylinder 32 integrally provided at the front end of the heating cylinder 32, And a nozzle pipe 31 protruding toward the front of the cylinder unit 10 through the nozzle pipe 13. The heating cylinder 32 is heated by an electric force and is capable of applying heat to the material contained in the inner space S. The power supply portion including the electric wire 34 is connected to the heating cylinder 32 to supply electric current to the heating cylinder 32. [ The piston main body 23 is slid along the inner wall surface of the cylinder 11 of the cylinder portion 10 and the heating cylinder inner wall surface 32a provided on the same plane to push the solder P in the melted state It can be jetted through the nozzle hole 33 of the nozzle tube.

The diameter of the nozzle tube 31 becomes smaller toward the end, so that the solder can be dropped by a small amount at an accurate position. According to the drawings, the end portion 31a of the nozzle tube 31 is an inclined surface.

The base body 23 may be made of a ceramic material for heat resistance. A ring-shaped packing 25 made of Teflon or heat-resistant rubber may be provided on the circumferential surface of the base 24 for the sealing function.

A step 12 protrudes radially from the rear end of the cylinder portion 10 so that the piston portion 10 can be pressed by one hand.

Hereinafter, another embodiment of the present invention will be described with reference to FIG.

According to the present embodiment, the cylinder 11 of the cylinder portion 10 is provided with the pull ring 15 to which the fingers can be inserted. A bar-shaped handle 26 is formed at the end of the rod 22 so that the piston 20 can also be gripped by hand. According to the present embodiment, a scanning type soldering mechanism can be used as if a pistol grip and a trigger are used.

According to the present embodiment, the heating means 30 is provided at the tip end of the cylinder portion in a short section. The piston main body 23 is designed not to descend to the heating means 30. According to this embodiment, molten solder is ejected by using the air pressure generated in the cylinder portion 10 as the piston portion 20 is pressed.

In the case where the piston body 23 does not reach the heating means, the shape of the heating means can be changed into various forms. For example, a fin may be projected toward the inner space P to facilitate heating more quickly.

The above description is only an example based on the technical idea of the present invention. Those skilled in the art will recognize that various modifications may be made by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims. For example, all embodiments described above may be freely combined and practiced by those skilled in the art, and any combination thereof should be construed as being included within the scope of the present invention.
