Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a solder feeding device in a manual soldering work.

[0002]

2. Description of the Related Art Conventionally, when temporarily fixing an electric component such as a resistor to a board, it is common practice to hold the electric component and thread solder in one hand and the soldering iron in the other hand. is there.

[0003]

However, when this method is used, it is necessary to concentrate the work on the arrangement of the electric parts at a predetermined position on the board and the feeding of the tip of the thread solder to a predetermined position, which is troublesome. The work of the soldering iron is neglected at the same time, and quick and reliable work cannot be performed.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to provide a device which is easy and quick to manufacture, and which enables reliable manual soldering work.

[0010]

The present invention will be described in detail with reference to the embodiment shown in the drawings. A rotatable winding frame 2 around which a thread solder 1 is wound, and a forward / reverse direction in which the thread solder 1 is sandwiched and fed out or pulled back. The feeding rollers 4, 4'driven by the motor 3 of FIG.
A flexible guide tube 5 which is located at the feeding opening of the la 4, 4'and has a tip extending outward, and a bending piece 11 which can be bent, and a gripping piece 11 which is in contact with the thread solder 11 at the tip of the guide tube 5. , 11 ′, which are driven by the control mechanism 10.

The control mechanism 10 comprises a control panel 7, a feeding timer-8 and a returning timer-9, and the motor 3 is connected to a feeding timer-8 which is determined by adjusting the feeding length of the thread solder 1. It is set so that the motor 3 is stopped when the thread solder 1 having a predetermined length is driven for a predetermined time and protrudes from the tip of the sensor 6.

The return timer 9 for the thread solder 1 after a certain period of time operates to reverse the motor 3 and the tip of the thread solder 1 is detected by the sensor.
When the contact is released after passing through 6, the reverse rotation of the motor 3 is stopped. After this stop (preferably about 0.1 to 0.6 seconds), the feeding timer-8 is operated to rotate the motor 3 in the forward direction and feed the yarn solder 1 for a predetermined length. It is designed to be repeated in the following order.

Reference numeral 12 in the drawing is a tension.

Although the sensor 6 is of the contact type, it may be of the non-contact type using an infrared sensor or the like.

[0015]

The present invention is embodied as described above. To use this, the thread solder 1 is pre-wound on the winding frame 2 and the tip is inserted between the rollers 4, 4 '. Flexible guide tube
The motor 3 is inserted through the sleeve 5 and continuously driven to bring it into contact between the sandwiching pieces 11 and 11 'of the sensor 6 so as to be projected for a predetermined length.

At this time, the feed-out timer of the control mechanism 10
8. Adjust the return timer-9 to adjust the pay-out length and return time of the thread solder 1, and flex while the tip of the thread solder 1 projects from the tips of the gripping pieces 4, 4 '. Solder while bending the guide tube 5 to a position where it can be easily operated.

After a certain period of time (standby time) that has been set regardless of the progress of the soldering work, the return timer-9 is activated to monitor the mode.
When the motor 3 reverses and the tip of the thread solder 1 passes through the sensor 6 and the contact is released, the motor 3 stops. The setting of the waiting time is determined by the relative relationship between the working time and the protruding length of the thread solder 1, but it can be freely adjusted.

After this stop (preferably 0.1 seconds to 0.6 seconds), the feeding timer-8 is operated to rotate the motor 3 in the normal direction so that the thread solder 1 is held between the sensor 6 and the clamp piece 11. It extends for a predetermined length while contacting between 11 '. The pay-out length of the thread solder 1 is determined by adjusting the adjusted pay-out timer-8.

[0019]

[Effect] The present invention is, as described above, the feeding roller 4, 4 which is driven by the rotatable winding frame 2 around which the thread solder 1 is wound, and the motor 3 which moves the thread solder 1 between the forward and reverse directions. 'When,
The thread solder 1 is inserted and the base end is located at the pay-out port of the pay-off rollers 4, 4'and the tip extends to the outside, and the flexible guide tube 5 that can be bent and the tip of the guide tube 5 are provided. It is composed of a thread solder 1 and a sensor 6 which can be contacted with each other. These motors 3 and 6 are connected to a control mechanism 10 including a control panel 7, a feeding timer 8 and a return timer 9. Since the thread solder 1 having a constant length can be freely moved in and out from the tip of the sensor 6 for a predetermined time, the parts to be temporarily soldered and the tip of the thread solder can be freely brought close by operating the flexible guide tube. Work can be performed, efficient safety and reliable work can be performed, and the used thread solder can be instantly replenished to the original length without waste of time, and the structure can be easily provided at low cost.
