Abstract

PURPOSE:To provide a brazing device which can supply automatically a flux in an automatic brazing stage by immersing the tip of a brazing rod in the flux so that the flux sticks to the tip of the brazing rod prior to supplying of the brazing rod by a means for supplying the brazing rod by a means for supplying the brazing rod. CONSTITUTION:A brazing rod 7 extends always for a specified length from the tip of a nozzle 6. An air cylinder 12 is actuated in this state to extend a piston 13 which turns a holder 9 around a shaft 11. More specifically, a means 4 for supplying the brazing rod is displaced downward and therefore the tip of the rod 7 is dipped into the flux 22 in a flux-contg. case 21 so that the pasty flux 22 is stuck thereto. The piston 13 is then returned to the home position and the air cylinder 5 of the means 4 is actuated to advance the nozzle 6. The rod 7 is therefore supplied toward the brazing position of preliminarily heated base metals 1 and at the same time the flux 22 sticking to the tip of the rod 7 is supplied to the position 3.

Description

[Detailed description of the invention] The present invention relates to an automatic waxing machine.

As is well known, several automatic brazing devices have been developed. For example, an index table type automatic brazing machine automatically performs preheating, 8-burner heating, wax supply, air cooling, water cooling, cleaning, Equipment that performs various processes such as air blowing and then solders has also been put into practical use and is widely used in various industrial fields.

These automatic welding methods are suitable for cleaning the base metal and preventing surface oxidation of the base metal and wax, as well as dissolving metal compounds generated during soldering, and cleaning the wax in a single step. 7 lux is applied to the solder joints to provide free flow and other functions.

Attempts have been made to automate the application of this 7-lux for automatic brazing connection layers, but it is still difficult to handle mechanically as the inner part of the flux is powder-like or paste-like. The reality is that no effective means of automatic application has been implemented.

Therefore, in the past, the actual situation was that this flux application was done manually. That is, before subjecting the base material to the brazing process, it is applied one by one using a brush or the like, and then transferred to the automatic brazing process.

Even though this A1 ■ industry is a 1! 1 process, and it is processed as efficiently as J tun ding, there is a limit to the improvement of the overall process.

In addition, after coating the base material as described above, the automatic brazing equipment goes through preheating and heating processes, and then enters the process of supplying the wax. A portion of the flux may evaporate and flow down due to the force of the UNI heat flame.

For this reason, a situation occurs in which the base material is partially heated without flux, resulting in oxidation even at low temperatures, resulting in pinholes and leaks in the soldered product. Furthermore, if the base material of the pond is soldered to the side of the base material,
Even if 7 lux is applied to that part, the wax may flow down in the direction F before starting the soldering process using the wax lining. In such a case, the same problem as above will occur.

The present invention was developed based on these points, and its gist is that the soldering material (base material) to be soldered is
a wax supply means for supplying wax to the solder contact position;
It has a heating means for heating the base material and a case for accommodating flux, and either part or both of the wax supplying means and the flux accommodating device is provided with the wax supplying means. A movable mechanism is attached for immersing the tip of the wax, which is slightly exposed from the nozzle, into the 7 lac through the 7 lac lu surface of the 7 lac, and before the wax is supplied by the zelkova supply means. This brazing device is characterized in that the tip of the solder is immersed in flux by operating a movable screw, so that the flux adheres to the tip of the solder. The object of the present invention is to provide an Htit that can automatically supply flux at the soldering point, and moreover, to provide a reading that can reliably and timely supply flux to the soldering position.

Therefore, even in the case where flux is applied to the base material in advance before the automatic process, it is necessary to provide a device that can re-supply flux to the wax level at the wax level. It is on offer.

Next, an example of the present invention will be described in detail with reference to the accompanying drawings.

No. 11iJ shows an example of an automatic brazing process. (At the 0 position, the base material---for example, pulp, cock, air conditioner a part, etc. Then, JJO heat and wax supply are carried out, and the motherboard is soldered.Then, it is air-cooled at the C position, and (00
It is cooled with water at the position (7') and taken out at the position (7'). Each of these steps is performed on a strict timer. In the conventional apparatus, flux application was carried out manually at the point 1d in point (2) above.

The brazing device according to the present invention is used when performing the above-mentioned process.Of course, even when using the present invention'A++it, in order to prevent acclimatization of the base material during preheating,
It is bad to apply 7 lux in the position of ■ and ■
In some cases, it is applied during preheating lσ.

Now, the first embodiment of 杢＠明 is shown in FIG.

In the figure, l indicates a base material consisting of members a and b.

This row shows an example in which part ib is soldered to the side surface of member a, and base material l is held by setting means 2.

This setting means 2 is attached to an index table (not shown), and the setting means 2 is attached to an index table (not shown). rJ is missing rotation.

The wax feeding means 4 are disposed obliquely so as to aim at the solder contact +t3 of the base material 1.

In the illustrated example, the nozzle 6 at the tip moves backward by +tff due to the reciprocating movement of the air cylinder 5, and the nozzle 6 moves backward by +tff at the forward limit position.
The solder shell 7 facing from the base metal l is at the solder contact position 3 at t#
This shows what is provided. The wax supply equipment 4 is supported by a machine stand 8 in a vertically movable manner.

That is, the holder 9 is held around the air cylinder 5 of the row # supplying means 4, the placket lυ is attached to the top of the local machine stand 8, and 1lill is placed between the placket 1o and the holder 9.
Because l is passed through, row 41A kaide e! < is supported by the undulating R. A rotating machine 412 is attached to the rear side of the top of the machine base 8, and is rotated from an air cylinder.
The tip of the piston 13 and the 11 surface 14 of the holder 9
has been achieved. Therefore, when the piston 13 extends, the wax supply means 4 held by the holder 9 changes to the original position, and when the piston 13 retreats to the original position 1d, the wax supply means 4 returns to its original position. to return to.

The above-mentioned machine stand 8 has an upper drive mechanism installed 5, and an F1tJ rear drive means 16.
, the left-right movement small setting 7 is set 4, and the fine adjustment in the three-dimensional direction is the second row.

A curved blade, wax 4 supplying means 4, nozzle 6 has a holder 18 attached thereto, a case holder I9 is fixed to the upper part of the holder 19, and the case holder 19 has a top surface. A flux storage case 21 that can be opened is set. It is desirable that the flux 22 in the flux storage case 21 is in the form of a paste.0 And, what is particularly important is that the air cylinder 5 forming the wax supply means 4 returns to the t & retreat limit, and then When displaced in the direction, the tip of the wax 47, which is the tip of the nozzle 6, is positioned so that it is immersed in the 7 lux 4 in the 7 lux storage case.

The operation will be explained based on this groove configuration. When the wax acid is finished in the previous step, the air cylinder 5 enters the retracting operation and the nozzle 6 returns to the retracting limit. The solid line diagram in Figure 2 is
This state is shown below. At this time, the wax 7 is facing the hole for a certain length from the base of the nozzle 6. At the time of this review, the air cylinder 12 that forms the town's support is operated to extend the bin 13. Therefore, the holder 9 rotates about the shaft 11 as a fulcrum. In other words, the row sleeve joint means 4 is displaced downward. For this reason, the tip of the wax 7 is immersed in the 7 lacs ρ in the blacks collection case 21, and 7 lacs in paste form is adhered thereto. This state is shown in a single point diagram in FIG.

Since the piston 13 of the air cylinder 12 that constitutes the wider gTIJJ mechanism returns to its original position, the wax supply means 4 returns to its original position, and then the air cylinder 5 of the wax supply means 4 returns to its original position.
operates and the nozzle 6 advances by +jfl.

Therefore, the wax 7 is supplied to the soldering position of the base material 1, which is being IJO-heated by the heating means of the burner (not shown). That is, along with the wax 14!7, the 7 ranox 4 attached to the tip of the wax #7 is supplied to the wax level filter 3. As this charcoal and air cylinder 5 return to their original positions, the next base material to be waxed is positioned at the brazing contact distance d, and the same operation is repeated.

In this way, the 7 lux a is automatically attached to the tip of the solder grain 7, and then the solder grain 7 is supplied to the base material 1 (1) cy welding device 3, so that the solder grain 7 can be applied to the solder joint accurately and at the right time. Flux 4 is often supplied. The supplied flux 4 not only prevents acclimatization of the wax storage, but also quickly flows to the wax-encumbered area to prevent acclimatization of the matrix, and evenly spreads the molten wax to the soldering area. spread widely.

Therefore, in the case where the base material is coated with flux in advance, even if the flux evaporates due to the preliminary f$44, 7 lux will be supplied at the time of waxing. A good wax acid can be produced. Also, like this example,
As in the case of waxing a member on the (1) side,
When applying flux to the side surfaces, there is a risk that it will flow down due to gravity even if the flux is applied in advance.If there is no flux at the time of supplying the wax, a situation like this will occur at any time. Since flux is also supplied when wax is supplied to the machine, good wax acid can be produced.

Next, a second example will be explained according to FIG. For convenience of explanation, the same parts are given the same reference numerals.

In this example, a mounting plate 18 on which the flux storage plate 21 is placed is shown.
In this case, the wax supply device 4 simply moves forward and backward to supply the wax 11!7. Just do it.

That is, the air cylinder 5 of the wax supply means 4 is moved back,
Nozzle 6 retreats. At this time, the wax head 7 is at the retraction limit with a head that is one radial % apart from the nozzle tip. Next, the air cylinder forming the movable mechanism moves upward to move the flux storage case 4 upward. The upper St lagoon is set at a position where the tip of the wax 7 is immersed in the 7 lux ρ in the 7 lac collection case 21, so 7 lux n is placed at the tip of the wax 7 at the upper limit of movement. adhere to. After that, the air cylinder constituting the movable mechanism moves F, and the air cylinder 5 of the wax 4 supplying means 4 operates, and the nozzle 6
is extended.

As a result, the wax 7 to which the flux 4 is attached is supplied to the wax level 7 of the base material, and the same soldering as in the previous actual case is performed.

In each of the above embodiments, the movable mechanism is shown as an air cylinder, but means such as hydraulic pressure, an electric motor, etc. may also be used. A single motion motor is equipped with a crank means and a lead spline hand +9 to convert rotational interlocking to reciprocating interlocking.
-1 is used.

Furthermore, both the flux storage case 21 and the flux supply means 21 of the above embodiment may be operated.Regardless of the first embodiment or the second actual case, the flux storage case 4 may be , it may be moved slowly and approximately horizontally within that range, provided that it allows the wax 7 to be immersed.

An air cylinder can be considered as a means for horizontally moving it in this way, but by doing so, the I! i! The pond, which can change the entire soaking position, helps to level out the 7 razox 4 in the flux storage case 21.

The first aspect of the present invention described in detail above includes a brazing supply means for supplying brazing to the brazing position of the soldering member to be brazed, and a brazing supply means for heating the soldering member. It is equipped with a D0 heating means and a 7 lux storage case, and one or both of the wax supply means and the flux storage case has a 7 lux accommodating case with a tip of the wax that slightly faces from the nozzle of the wax supply means. A movable mechanism is attached for immersing the flux into the flux through the opening surface of the storage case, and the movable mechanism is moved before supplying the wax to the wax level 1f of the soldering member. This is a brazing device that is characterized by immersing the tip of the wax in 7 lux to adhere 7 lac to the tip of the wax, so the automatic brazing device can automatically add 7 lac to the tip of the wax. It has the advantage that it can be supplied to the wax of the wax contact member at the hair position.Since it is attached to the tip of the wax, it can be supplied to the wax contact position along with the wax.

Also, since it is supplied in synchronization with the raw salary, the timing is good. Furthermore, since the wax tip is simply immersed in the 7 lacs in the 7 lacs storage case, it can be carried out simply and easily, and it can be well matched with the two factories in the automation pond. Also, apply 7 Lanox to the pre-swaged base material and preheat it.)
J[I] Even if the wax applied in advance evaporates or flows when the fence is applied through a heat process, this device will By attaching it, you can sufficiently compensate for the flux lost at the tip, and prevent poor soldering, leaks due to pinholes, and cracks on the soldering surface, making it possible to perform more effective soldering. It is an enabler of advantages.
