  FIG. 1 shows a first embodiment of an automatic soldering apparatus according to the present invention.

  In the automatic soldering apparatus of the first embodiment, the iron unit 1 is attached to an arm 2 capable of coordinate control of the x-axis, y-axis, and z-axis. The arm 2 can be moved by a servomotor along the x-axis rail 2a and the y-axis rail 2b. With respect to the z-axis, the z-axis arm 2c is moved up and down by the servomotor. Each tube connected to the iron unit 1, that is, an electric wiring tube, an air tube, a solder feeding tube, etc., is once collected on the disk-shaped umbrella member 3 provided above the iron unit 1 so as not to get entangled. Has been processed.

  As shown in detail in FIG. 2, the iron unit 1 holds the iron 1a with a holding arm 1c protruding from the suspension portion 1b, and the iron 1a is supported so that it can be retracted upward in the drawing. . The gripping arm 1c is urged in the forward direction, which is downward in the drawing, by an urging means such as a coil spring of a suspension provided in the suspension portion 1b. Therefore, the iron 1a grasped by the grasping arm 1c is also simultaneously urged in the forward direction, and the iron tip 1d of the iron 1a is elastically brought into contact with the object S to be soldered. The tip weight is applied.

  The iron 1a includes a holder 1e fixed to the gripping arm 1c and a replaceable iron tip 1d held by the holder 1e. A flange 1g for attaching a supply nozzle 1f that feeds the solder wire toward the iron tip 1d is provided around the tip of the holder 1e.

  In the automatic soldering apparatus according to the first embodiment, the tip weight meter 4 is provided at a position different from the jig portion J on which the object S to be soldered is placed. The iron tip weight meter 4 is provided within the movable range of the arm 2, and the iron tip 1 d of the iron 1 a can be brought into contact with the operation of the arm 2. When the tip 1d is brought into contact, the tip weight generated by the suspension 1b is measured, and a numerical value is displayed on the display unit 5 of the operation panel.

  The iron tip weight meter 4 can be configured using a strain gauge, a piezoelectric element, or the like, and measures the iron tip weight by converting the pressure applied from the iron tip 1d into an electrical signal. Then, an upper limit value and a lower limit value for the measurement value can be set, and when the measurement value exceeds the setting range, an error display may be performed through the display unit 5 or the like.

  According to the first embodiment described above, since the solder tip weight meter 4 is provided, the solder tip weight can be measured and managed even after the automatic soldering apparatus is installed on the production line. That is, the user can continue to manage the iron tip weight.

  In the automatic soldering apparatus according to the first embodiment shown in FIG. 1, since the tip weight meter 4 is installed at a position different from the jig portion J, the soldering is being performed on the object S. The tip weight cannot be measured. Therefore, FIG. 3 shows a second embodiment in which the iron tip load during the soldering operation can also be measured. Hereinafter, the description of the parts common to the first embodiment will be omitted.

  The automatic soldering apparatus of the second embodiment is different in the structure of the jig portion J, and includes four struts J1 on which the object S is placed, a support base J2 of the strut J1, and a lower side of the support base J2. And a solder tip weight meter J3 provided in the head. The iron tip weight gauge J3 uses a strain gauge or a piezoelectric element similarly to the iron tip weight gauge 4 of the first embodiment, and converts the pressure applied from the iron tip 1d in contact with the object S into an electrical signal. The tip weight is measured, and the measured value is displayed on the display unit 5. Further, as described above, an upper limit value and a lower limit value for the measurement value are set, and when the measurement value exceeds the set range, an error can be displayed through the display unit 5 or the like.

  As in the second embodiment, FIG. 4 shows the inside of the iron unit of the third embodiment that can also measure the iron tip load during the soldering operation. The soldering apparatus according to the third embodiment is an example in which a solder tip weight meter 1h is incorporated in the suspension portion 1b of the solder unit 1.
