It is still another object of the present invention to provide an automatic soldering machine which has a uniform soldering and reliability because the soldering operation is performed by setting the soldering temperature of the iron to an optimum temperature for the soldering member.

An object of the present invention, the workbench is provided with a hollow column,

A soldering iron detachably coupled to a frame rotatably coupled to the pole and rotatable,

Lead supply means for automatically supplying the lead wound on the reel rotatably installed on the work table to the end of the iron;

Hazardous gas discharge means for sucking the solder smoke generated during soldering by the suction pipe connected to the top of the column and discharged by the suction fan drive formed in the discharge pipe connected to the bottom of the column;

It is achieved by providing an automatic soldering machine, which is installed on a work table, selects a work mode according to a signal input by a switch operation by a user, and has a control unit having a control panel that can variably adjust the iron temperature.

According to a preferred embodiment, it is provided with a pedestal for stably supporting the wrist of the user holding the soldering member mounted on the workbench and soldered by the iron.

Also, a foot switch is used as the switch described above.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, which are intended to describe in detail enough to enable those skilled in the art to easily practice the present invention. It does not mean that the technical spirit and scope of the invention are limited.

As shown in Fig. 1 to 5, the automatic soldering machine according to the present invention, the worktable 2 is provided with a hollow pillar (1) is installed, and the frame (3) rotatably coupled to the pillar (1) ), A iron (4) formed on a fixing table (14) rotatably and detachably coupled to the frame (3), a reel (5) rotatably installed on the work table (2), and with a lead (6) wound thereon; Solder harmful to the human body generated during soldering by lead supply means for automatically supplying lead (6) wound on reel (5) to the end of iron (4), and suction pipe (7) connected to the top of column (1) It is provided with harmful gas discharge means for inhaling dust, gas and the like due to the driving of the suction fan 21 by the drive motor 22 mounted on the discharge pipe (8) connected to the lower end of the column (1).

In addition, the work table 2 is installed on the work table 2 described above, and the work mode according to the work type can be selected according to the signal input by the user's foot switch operation, and the temperature of the iron 4 can be adjusted. A stand for stably supporting a user's wrist holding a control unit 11 having a control panel 10 and a soldering member (not shown) such as an IC mounted on the work table 2 and soldered by the iron 4. (12) is provided.

At this time, the above-described lead supply means, the roller 13 is rotatably mounted to the frame 3, and the pair of rollers 17 mounted to the rotating piece 16 rotatably coupled to the fixing table 14 and And a lead transfer drive motor 18 for driving the roller 17 to feed the lead 6 wound on the reel 5.

In the figure, reference numeral 15 denotes a caster rotatably mounted on the back of the worktable 2, 20 is a power plug for supplying commercial power from the outside, and 23 is passed through the roller 17 to the end of the iron 4. It is a tube for guiding the lead (6) to be transferred.

Hereinafter, a use example of the automatic soldering machine according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 5, when a circuit component such as an IC (hereinafter referred to as a soldering member) is to be soldered to a printed circuit board embedded in various electrical and electronic products, the soldering member is seated on the work table 2 described above. By operating the corresponding button mounted on the control panel 10, the commercial power is applied to the driving motor 22 for driving the lead transfer and the driving motor 22 for driving the suction fan 21 through the power plug 20. Complete a task that can be initialized.

At this time, as the operator presses the foot switch 9, the control panel 10 selects the required working mode according to the soldering operation of the soldering member. That is, in the first mode, the component (that is, the driving motors 18 and 22) is pre-programmed to be driven only for a predetermined time when the foot switch 9 is pressed. In the second mode, the foot switch 9 is It is pre-programmed so that the above-mentioned part is driven only during pressurization.

Therefore, when the foot switch 9 is pressurized, the lead 6 is supplied to the welded portion of the soldering member placed on the work table 2, and at the same time, the soldered part can be soldered by the iron 4 heating. As the pair of rollers 17 are driven by the drive motor 18 for lead transfer, the lead 6 wound on the reel 5 is mounted on the frame 3 by the frictional force of the rollers 17. After passing through the roller 13 and the roller 17 in order, it is guided by the tube 23 and supplied to the end of the iron 4.

At this time, the soldering temperature of the iron 4 can be varied according to the type of soldering member within the range of 200 ~ 450 ℃. That is, the soldering temperature is selected by operating the corresponding button mounted on the control panel 10, or soldering is performed by a preset temperature.

That is, the iron 4 has a constant temperature because the detected signal of the temperature sensor mounted on the iron 4 is applied to the control panel 10 to control the temperature so that the set temperature is kept constant during operation. It can maintain uniform soldering work.

On the other hand, harmful gases harmful to the human body such as solder smoke, dust and harmful gases generated during soldering can be easily discharged from the soldering workshop.

Pass through and discharge to the outside.

On the other hand, the height and direction of the iron 4 can be easily adjusted according to the shape and shape of the soldering member. That is, by operating the fastening member 3a, the frame 3 on which the iron 4 is fixed is moved up and down with respect to the column 1, and at the same time, it is possible to rotate in the circumferential direction so that the height and direction of the iron 4 can be easily changed. Changes can improve workability.

In addition, the angle of the iron 4 can be easily changed according to the shape and shape of the soldering member. That is, by operating the fastening member (4a) can be rotated with respect to the frame (3) fixed to the iron 14 is fixed to the frame (3) can easily change the iron 4 angle to improve workability.

On the other hand, according to the shape and shape of the soldering member can be easily adjusted the lead (6) supply direction. That is, by operating the fastening member 16a, the rotating piece 16 on which the roller 17 is fixed can be rotated in the horizontal direction with respect to the holder 14 (possible to rotate within the range of 260 degrees). Easily change direction to improve workability.

In addition, by placing both wrists of the operator on the pedestal 12 installed on one side of the workbench 2 described above, the soldering member is held and supported by both hands, so that the soldering member is prevented from shaking and the soldering welding is made precisely. By keeping comfortable, worker's fatigue can be significantly reduced.
