Reference numeral 1 denotes a workpiece on which electronic components and the like are placed and soldered. The solder feeding section 3 supplies the thread solder 2 to a soldering portion a of the workpiece 1. .

The solder feeding section 3 sandwiches the thread solder 2 between a pair of rollers, and turns the pair of rollers by a motor or the like (not shown) so that the thread solder 2 can be sent or returned. The thread solder 2 coming out of the solder feeding section 3 is inserted into a hollow introduction pipe 4 bent in the direction of the soldering section a and supplied to the soldering section a.

The thread solder 2 is wound around a rotatably held bobbin 5, and when the thread solder 2 runs out, it is replaced with a bobbin 5 wound with the thread solder 2.

The introduction pipe 4 is provided with a detection section 6 for detecting the feeding state of the thread solder 2.

The solder feeder 3, the inlet pipe 4, the bobbin 5, and the detector 6 are held by a head 7.

0, the irradiation unit 9 is movable.

The solder feeder 3, the detector 6, the heat source 1
0, the detection unit 10a, and the moving means 13 are connected to a control unit 15 via a control cable 14, and the control unit 15 performs operation control and operation state determination.

The control unit 15 includes an input / output unit 16, a CP
U17 and a storage means 18, and the storage means 18 stores operation programs of the solder feeding section 3, the detection section 6, the heat source 10, and the moving section 13 relating to the soldering work. The input / output means 16 controls the solder feeder 3, the detector 6, the heat source 10, and the moving means 13.

During the normal soldering operation, the above-mentioned solder feeding section 3, heat source 10, and moving means 13 are operated according to the control program to perform soldering as appropriate. Control unit 15 based on a signal from
However, when it is determined that the solder, that is, the breakage of the solder or the problem caused by the heat source has occurred, the CPU 17 first stores the current working position in the storage unit 18 and stops the heat source 10 as a process of the CPU 17. As shown in FIG. 2, the moving means 13 is driven to drive the torch 11 through the arm 12.
The (head unit 7, heat source 10) is moved to a maintenance position such as a solder replacement position or a heat source repair position, which is stored in advance, and the device is automatically stopped after the torch 11 reaches the maintenance position.

After that, the operator corrects the problem (in the case of solder, that is, the solder clogged in the introduction pipe 4 is removed, and in the case of broken solder, the bobbin 5 is replaced with a rolled solder, and the heat source is removed. If the problem is caused by the heat source 10
Replacement or repair).

After the repair work, when the work is resumed (the apparatus is restarted), the moving means 13 is operated at the position where the work stored in the storage means 18 is interrupted, and the torch 11 (the head 7, the heat source 10) is operated. , And then the heat source 10 is operated to resume the operation.
