Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoke damage preventive soldering iron.

[0002]

2. Description of the Related Art Generally, in a soldering robot or a soldering work, smoke generated therein adheres to a movable part such as a holder or a joint and has an adverse effect. Conventionally, in order to prevent smoke damage in the soldering work, the soldering iron and the robot are regularly cleaned, and as shown in FIG.
Smoke generated by 21 and local suction means 23 disposed in the vicinity thereof
It is aspirated and eliminated by.

[0003]

By the way, in the above-mentioned prior art, when the local suction means 23 is mounted on the soldering robot, if the suction tube 24 is too thick, it hinders the movement of the robot arm or interferes with the work. If the suction tube 24 is too thin, it will be clogged with just a small amount of suction, and it will have to be cleaned frequently.In addition, even when soldering by hand, the generated smoke will rise due to the rising airflow due to the iron heat. Therefore, there is a problem that it cannot be sufficiently sucked and removed.

The present invention has been made in view of the above-mentioned circumstances, and the purpose thereof is to surely suck and remove the generated smoke, to completely prevent smoke damage, and to avoid frequent cleaning. It is to provide a smoke damage prevention soldering iron suitable for a soldering robot.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention is characterized in that a cover for covering the trowel body excluding its tip is attached to the holder of the soldering iron, an air supply pipe is connected to the cover, and air is blown out from the tip of the cover. .

Further, the present invention is characterized in that an inner cover for preventing a temperature drop is attached to a tip portion of the trowel body. Furthermore, the present invention is characterized in that the cover has a double structure with an inner and outer cylinder, and air is supplied between the inner and outer cylinders.

[0007]

According to the present invention, the fresh air blown from the tip of the cover pushes back the rising smoke generated by the heat of the tip of the iron body to push back the smoke, and the dirt such as smoke adheres to the soldering iron and its peripheral equipment. Can be prevented. The air pushed back by the air is effectively sucked and removed by the local suction means.

Further, by providing an inner cover or a cover having a double structure for preventing temperature drop at the tip of the iron body,
Maintains the iron tip temperature at an optimum level and allows good soldering.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment in which the present invention is applied to a soldering robot, 1 is a soldering iron, 2 is a trowel body, 3 is a trowel holder, 4 is a power wire, 5 is a cover,
6 is a solder supply device, 7 is an inner cover for preventing temperature drop,
8 is an air supply pipe, and 9 is an air amount control valve.

The cover 5 has a cylindrical shape with a canopy, and has a trowel body insertion hole 10 in the center of the canopy 5A. The trowel body 2 is inserted into the hole 10 to fix the canopy 5A to the trowel holder 3. There is. An air supply pipe is provided on the side surface of the cover 5 near the canopy 5A.
8 is connected through the valve 9. The length of the cover 5 is such that the tip of the iron body 2 projects from the opening end 5B by a required length, and the opening end 5B is slightly reduced in diameter so that air can be efficiently blown out. is there.

The inner cover 7 has a cylindrical shape, and its inner end is fixed to the large diameter portion 2A of the intermediate portion of the trowel body 2 so that the position of the outer end can be adjusted. The soldering device 6 is attached to the cover 7 so that the solder 11 is automatically supplied. In the first embodiment, when performing the soldering work, as shown in FIG. 2, when the local suction device 13 is arranged on the work floor 12 and the work is started, an appropriate amount of fresh air is generated at the cover opening end 5A. The inner cover 7 is blown out from between the tips of the iron cover 2 and pushes back the smoke 14 rising due to the ascending air current generated by the heat of the tip of the iron body 2 to prevent the smoke from being attached to the soldering iron 1 and the movable parts such as the joints of the robot. The smoke is removed and the smoke is led to an external dust collecting facility by the local suction device 13.

Since the inner cover 7 prevents air from directly contacting the tip of the trowel body 2, a temperature drop can be prevented, an optimum iron tip temperature can be secured, and good soldering can be performed under favorable conditions. it can. The air is supplied by compressed air used for driving the robot or by a separately installed compressor, fan, etc., and the amount of air blown out is adjusted by the valve 9.

FIG. 3 shows a second embodiment in which the present invention is applied to a manual soldering iron, and a cover 15 having a double structure for covering the soldering iron body 2 of the soldering iron 1 excluding the tip is used for the soldering iron holder 3.
The cover 15 is composed of an inner cylinder 15A and an outer cylinder 15B. The open end of the inner cylinder 15A is made slightly longer than the open end of the outer cylinder 15B so that the air blown out from the iron body 2
Do not directly touch the tip of the.

The air supply pipe 16 is an outer cylinder of the cover 15.
15B is connected to the iron holder 3 near the
It is designed to be supplied between A and 15B. In the second embodiment, when performing the soldering work, when the soldering is performed while blowing fresh air from the tip of the cover 15,
The generated smoke is blown by the fresh air toward the local suction device, the rising air flow due to the heat generated by the iron tip disappears, the worker does not inhale the rising smoke, and there is no risk of health damage due to smoke. . Further, according to the second embodiment, the temperature drop of the iron body 2 can be completely prevented, and the bad influence on the soldering can be eliminated, so that good soldering can be performed and the soldering can be made robust and the cover can be attached. Is easy.

The present invention is not limited to the above-mentioned embodiment, and for example, the first embodiment can be adopted in a manual soldering iron, and the second embodiment can be adopted in a soldering robot. Further, in the first embodiment, the inner cover 7 can be fixed to the outer cover 5, and the design can be changed appropriately.

[0016]

As described above, according to the present invention, the holder for the soldering iron is provided with the cover for covering the iron body except the tip thereof, the air supply pipe is connected to the cover, and the air is blown out from the tip portion of the cover. Since it is characterized by doing so, the rise of generated smoke is prevented to prevent dirt such as smoke from adhering to the soldering iron, smoke damage is prevented and frequent cleaning is not required, and a local suction device ensures reliable operation. It can be removed by suction, and harm to the human body can be eliminated, and its compact size does not hinder its movement even when it is attached to a soldering robot, and does not interfere with work.

Further, the present invention is characterized in that the tip portion of the trowel body is provided with an inner cover for preventing temperature drop, so that the air blown to the tip portion of the trowel body does not come into direct contact with the trowel body and the temperature drop thereof occurs. Can be prevented, the temperature can be maintained at the optimum temperature, and good soldering can be achieved. Furthermore, in the present invention, the cover has a double structure with an inner and outer cylinder,
Since it is characterized by supplying air between the outer cylinders, the structure can be made simple and robust,
In addition, it is easy to attach to the holder, the temperature of the tip of the iron body can be prevented from lowering, and the temperature of the iron tip can be maintained at the optimum temperature, good soldering can be performed, smoke damage can be prevented, and adverse effects on the human body can be eliminated.
