Description

    The present invention relates to an automatic soldering iron.

The automatic soldering iron that solders thread solder secures the movement of the soldering position by air cylinder and motor drive instead of the soldering iron used for manual operation, and also has a position movement confirmation detection sensor. Is not generally used as an automatic soldering iron, hand-held soldering iron is held in human hands, soldering accuracy depends on its proficiency, and the difficulty of soldering work has become an obstacle to product quality and productivity Yes. The automatic soldering iron has a limit in reproducing delicate soldering work like a human hand. The soldering tip incorporated in the soldering iron is a consumable item, and the automatic soldering tip is more expensive than the hand soldering. Furthermore, the automatic soldering iron is larger in weight and size than the hand soldering iron.

    An automatic soldering iron with a mechanism that can reduce the price of the iron tip, which is a consumable part of the automatic soldering iron, reduce the size and weight of the iron, simplify it, and perform a delicate soldering operation like a human hand. desired. In addition, a data management method for optimizing manual work using a commercially available hand soldering iron has not been established.

  In recent years, commercially available hand soldering irons have also been improved to reduce the size and weight, the tip replacement is one-touch, and the accuracy of mounting dimension reproducibility has also been improved, whereby hand soldering irons are used as automatic soldering irons.

The wire actuator moving body to which the soldering iron is attached is moved by the spring incorporated in the wire actuator fixed body, the wire being unwound in the direction of the soldering position by pneumatic pressure, etc. The same soft landing as that of fineness is performed, and variations in solder positions are absorbed.

The soldering iron holder for attaching the soldering iron to the wire actuator moving body is provided with a fluctuation operation function effective in absorbing the ambiguity of heat transfer.

  Attach a soldering iron to the moving body of the wire actuator that uses a spring or pneumatic pressure on the return side, rotate the drum with a motor that can control the position of the moving body of the wire actuator, and wind up the wire. Are connected through the inside of the outer tube, and the outer tube is fastened by an actuator fixing member and a drum case.

Combines an automatic yarn solder feeder and a wire actuator automatic soldering iron using a manual soldering iron, extracts data on the optimum soldering conditions of the manual soldering iron, and manages the soldering based on the data as manual soldering data .

The automatic soldering iron is often used by being mounted on a robot or the like. In that case, the driving mechanism, wiring, and piping increase the load and operation restrictions of the robot. In the automatic soldering iron of the present invention, the soldering iron driving mechanism is soldered. Since it is not integrated with the iron, wiring and piping do not need to be attached to the soldering iron, the size and weight can be reduced, and the load and operation restrictions of the robot can be reduced, and maintenance can be reduced.

Automatic soldering irons can be made up of cheap, lightweight and small hand-held soldering irons, especially consumable ironing tips.

        The soldering iron movement to the soldering position can be soft-landed using a wire actuator and a spring, etc., and the delicate work of the hand can be realized.

        The fluctuation function of the solder cage absorbs the ambiguity of the soldering iron heat transfer.

        When combined with an automatic thread solder feeder, data on the optimum soldering conditions for commercially available manual soldering irons can be created.

    A commercially available hand soldering iron is attached to a moving body of a wire actuator that returns with a spring or the like through a cage having a fluctuation function, and the wire is connected to the moving body and passes through an outer tube attached to the actuator fixing body.
