Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a flux coating device that applies a flux solution to the stripped end of a covered electric wire.

(Prior art and its problems) Conventionally, this type of device pumps up the flux solution in the flux tank using a circulation device such as a circulation pump, and jets the flux solution downward from an upper position. There is an apparatus (for example, Japanese Patent Application Laid-open No. 118284/1984) that allows the stripped end of a covered wire to pass through the area and applies a flux solution to the stripped end.

Incidentally, in the above-mentioned apparatus, a flux tank, a circulation device, a pan for collecting surplus flux solution, etc. are integrated in order to collect surplus flux solution in a flux tank and reuse it. Therefore, if the operation of the circulation system is stopped for a long time, the flux diluted solution in the flux solution will evaporate during that time, causing flux to build up on the internal bottom of the flux tank, circulation system, pan, or pipes connecting these. The stock solution precipitates and solidifies, making circulation of the flux solution impossible. As a result, there is a problem that the device no longer functions as a flux coating device. In this case, a possible solution is to add a new flux diluent, but simply adding a flux diluent will not dissolve the precipitates and coagulates easily and will remain on the internal bottom of the pipe, etc., so the above measures are not recommended. It's not a real solution. Here, for example, the stirrer disclosed in Japanese Patent Application Laid-Open No. 53-35158 may be provided in the flux tank, but this would complicate the device configuration. Another problem arises in that the cost of the flux coating device increases.

Furthermore, since the flux solution contains chlorine, corrosion of metal members by the flux solution poses a problem. In particular, since the above device is a jet type, the flux solution scatters around the device when the flux solution is jetted, corroding metal members around the device.

(Purpose of the invention) This invention was made in order to solve the above problems, and the sixteenth purpose is to have a simple structure that prevents the flux stock solution from stagnating as the flux dilution solution evaporates.
It is an object of the present invention to provide a flux coating device that can easily dissolve the precipitate and coagulation even if the flux coagulates, and can apply a flux solution to the stripped end of a coated wire. The second purpose is to reduce or prevent scattering of the flux solution during flux application. The object of the present invention is to provide a flux coating device.

(Means for Achieving the Object) The invention of claim 1 is a flux application device that applies a flux solution to the stripped end of a covered wire at a predetermined flux application position, which achieves the first object. In order to do this, a flux tank for storing a flux solution, a stirring rod having a screw part,
and a driving means for rotationally driving the stirring rod in the flux tank, and by driving the stirring rod to rotate, the flux solution in the flux tank is stirred and the flux solution is directed upward. a stirring mechanism for transporting the flux solution; a partition plate for guiding the flux solution carried upward by the screw part to a flux application position; and a partition plate for guiding the flux solution carried along the partition plate at the flux application position to the coating and a flux applying means for applying flux to the stripped end portion of the electric wire.

In addition, in order to achieve the second object, the device of claim 2 includes the flux applying means being provided at the flux applying position and holding the flux absorbing material impregnated with the flux solution and the covered electric wire. and a wire holding and moving means for moving the covered wire so as to press the stripped end of the covered wire against the flux absorbing material and applying the flux solution to the stripped end. .

(Embodiment) FIG. 1 is a cross-sectional view showing an embodiment of the flux coating device according to the invention, and FIG. 2 is a view taken along the - line in FIG. 1. As shown in Figure 1,
This flux application device includes a flux tank 2 that stores a flux solution 1, a stirring mechanism section 3 that stirs the flux solution 1 in the flux tank 2, and a system for guiding the flux solution 1 stirred by the stirring mechanism section 3 to a flux application position. the partition plate 16 and the flux solution 1 guided by the partition plate 16
a flux applying means 5 for applying flux to the stripped end 4a of the covered wire 4 at a flux applying position; and a receiving tray 6.
It is made up of.

The flux tank 2 is made of a material that is corrosion resistant to the flux solution 1, such as vinyl chloride. Further, a flux application window 7 is provided on the outer peripheral surface of the flux tank 2 at a position facing the stripped end 4a of the coated wire 4, that is, at a flux application position.

The stirring mechanism section 3 includes a motor 8, a motor support member 9, a helical coupling 10, a shaft 11, and a bearing 1.
2, a connecting member 13 and a stirring rod 14. The motor 8 is fixed to a motor support member 9, and its drive shaft 8a is connected to one end of a shaft 11 by a helical coupling 10. Here, the shaft 11 is rotatably supported by the motor support member 9 via a bearing 12. The other end of the shaft 11 is connected via a connecting member 13 to a stirring rod 14 having a screw at a lower position. That is, the stirring mechanism section 3 drives the stirring rod 1 by driving the motor 8.
4 in the direction X (Fig. 2) around the vertical axis,
The flux solution 1 in the flux tank 2 is configured to be stirred. For this reason, the stirring rod 14
As the screw rotates, the flux solution 1 is carried upward along the screw portion.

The flux application means 5 includes a flux absorber 15 such as a sponge, and a wire holding and moving means (not shown).
It is made up of. The flux absorber 15 is arranged at a flux application position corresponding to the flux application window 7 and is fixed by a partition plate 16.

The flux tank 2 and the partition plate 16 are connected and fixed by bolts 17, and the flux tank 2 and the stirring mechanism section 3 are also connected and fixed by bolts 18.

Next, the operation of the flux coating apparatus configured as described above will be explained. First, prior to flux application, the motor 8 is driven and the stirring rod 1
4 rotates in direction X (Fig. 2) around a vertical axis.
As a result, the flux solution 1 in the flux tank 2 is stirred, so even if precipitated coagulation of the flux solution 1 is deposited on the bottom of the flux tank 2, it is easily dissolved. Further, the stirred flux solution 1 is applied to the flux absorber 15 at the flux application position along the path Y by the action of the screw part of the stirring rod 14 and the partition plate 16.
guided by. That is, when the stirring rod 14 rotates, the flux solution 1 stirred in the flux tank 2 is carried upward by its screw portion, as is well known in the art. Furthermore, the flux solution 1 flows on the partition plate 16 and is guided to the flux application position. As a result, the flux solution 1 is supplied to the upper part of the flux absorber 15,
Furthermore, the flux solution 1 is diffused throughout the flux absorber 15 from that portion, and the entire flux absorber 15 is impregnated with the slack solution 1. This makes it possible to start flux application.

Next, the wire holding and moving means (not shown) holds the covered wire 4 to which the flux solution 1 is to be applied, while pressing the stripped end 4a against the flux absorber 15 through the flux application window 7. The covered electric wire 4 is moved in the P direction. As a result, the flux solution 1 is applied to the stripped end portion 4a of the covered wire 4.

Thereafter, when the application of the flux solution 1 is completed, the wire holding and moving means moves the covered wire 4 in the Q direction while holding it.

As described above, the stripped end 4a of the covered wire 4
The application of flux solution 1 to the substrate is completed.

Note that when the amount of flux solution 1 in flux tank 2 decreases, remove replenishment lid 19 and
Flux solution 1 can be replenished from there.

As described above, the flux coating device according to the present invention is configured so that the stirring bar 14 rotates to stir the flux solution 1 in the flux tank 2, so that the precipitated coagulum of the flux solution 1 is removed. Can be easily dissolved. Furthermore, at the same time as the stirring rod 14 rotates, the stirring mechanism section 3 cooperates with the partition plate 16 to transport the stirred flux solution 1 to the flux application position, eliminating the need for a circulation device and simplifying the configuration. become. Further, the flux tank 2 and the stirring mechanism section 3 are connected to each other by bolts 1.
8, the stirring mechanism section 3 can be removed by simply removing the bolts 18. Therefore, it is easy to disassemble and clean the flux coating device.

Furthermore, a flux absorber 15 such as a sponge is impregnated with the flux solution 1, and the stripped end 4a of the covered wire 4 is pressed against the flux absorber 1 so that the flux solution 1 is applied to the stripped end 4a. Therefore, there is less risk of the flux solution scattering around the device as in the conventional case, and corrosion of metal members around the device can be reduced or prevented. Note that even if some of the flux solution 1 is scattered when applying the flux solution 1 to the stripped end 4a, it will be collected by the saucer 6, so that metals around the device due to the flux solution 1 scattering will be collected. Corrosion of the components is almost completely prevented.

In the above embodiment, the case where the flux application means 5 is composed of the flux absorber 15 and the electric wire holding and moving means (not shown) is explained, but the flux application means is not limited to this, and for example, It may be of a conventionally well-known jet type. In this case, stirring of the flux solution has the effect that precipitates and coagulation of the flux solution can be easily dissolved.

(Effect of the invention) As described above, according to the flux coating device according to the invention of claim 1, the flux solution is stored in the flux tank, and the flux solution in the flux tank is stirred by the stirring mechanism. Therefore, even if the flux undiluted solution of the flux solution precipitates or coagulates due to the evaporation of the flux diluted solution of the flux solution, the precipitate and coagulate can be easily dissolved. . Furthermore, the flux solution stirred in the flux tank is carried upward by the rotation of the stirring rod, and the flux solution is further guided to the flux application position, so that the flux can be easily applied with a simple configuration. While stirring the flux solution in the tank, the stirred flux solution can be applied to the stripped end of the coated wire.

According to the flux applicator according to the invention of claim 2, the flux applicator is provided at the flux applicating position, and while holding the flux absorbing material impregnated with the flux solution and the covered wire, and a wire holding and moving means for moving the covered wire so as to press the stripped end of the covered wire against the flux absorbing material and applying the flux solution to the stripped end. In addition to the effects, scattering of the flux solution during flux application can be reduced or prevented.
