Description

Brazing device that prevents malfunction of conveyor by flux {A device for brazing check the a bad movable of a conveyer on flux}

The present invention is a configuration in which a collecting chamber is provided at the inlet or outlet of the brazing apparatus to collect the flux of particles or molten state, the movement of the conveyor by the flux to prevent the conveyance of the conveyor by the flux attached to the conveyor A brazing device in which a defect is prevented.

In general, brazing is to join the base material with a filler metal in which the brazing object is melted by a constant heat below the melting point, and the brazing is heated to below the solidus temperature of the base material. Joining the brazing object to the base material with a filler material having a liquidus temperature of more than 450 ℃.

That is, the filler metal that has reached a certain temperature is melted by the capillary phenomenon, soaking between the base material and the brazing object to join.

Here, the property of expressing the affinity between the base material and the brazing object is called wetting, and if the wetting of the base material to be brazed is bad, the bonding force is reduced, resulting in incomplete bonding.

Conventional continuous brazing automation device, supply base for supplying a base material having a filler material, a preheating unit for preheating the base material supplied from the supply base, a heating unit for heating to braze the base material preheated in the preheating unit to the filler metal, A cooling unit for cooling the base material brazed in the heating unit, an outlet for discharging the cooled base material to the cooling unit, a conveyor belt for continuously transferring the base material from the supply base to the discharge zone, and a drive connected to drive the conveyor belt Contains a motor.

In addition, the preheating unit is provided with a preheating tube for transferring the base material, the preheating tube is built in the preheater to preheat the base material supplied from the supply table, the atmosphere to form the preheated base material by the preheater in a reduced state Atmospheric gas to form a is supplied to the preheating tube.

And the preheating unit is provided with a gas curtain to block the outside air flowing through the supply pipe supply pipe, the heating unit consists of a plurality of zones with a built-in heating heater to sequentially increase the heating temperature for heating the base material, While passing through the plurality of zones, the base material gradually rises in temperature to be brazed into the filler metal.

The brazing device as described above is preheated while passing through the preheating unit, starting with the supply stage, while the to-be-joined material with the filler metal is continuously transferred by the conveyor belt in the state of being set to the jig, and brazing while passing through the heating unit. It is cooled while passing through the cooling unit is discharged to the discharge.

Conventional brazing apparatus using a brazing method associated with such a technique is disclosed in Korean Patent Laid-Open No. 2003-28856, the configuration of which is a conveyor (circulated and rotated by a transmission means 102), as shown in FIG. 104) The plurality of heat sinks are inserted at equal intervals, so that the prefabricated aluminum products are moved forward and moved, so that each of the oil dryers 110, FLUX (solvent) sprayers 120, and FLUX dryers 130 installed above are installed. It is applied to the product.

At this time, the removal of the oil layer formed on the surface of the product by the oil dryer 110 is for smooth adsorption because the powdered FLUX is injected in a mixed state with water, and sprayed on the product by the FLUX dryer 130 Drying the applied FLUX is to remove moisture since the FLUX is applied in a mixed state with water.

Therefore, heating and melting in the brazing furnace 70 by the conveyor 104 in a state where a certain amount of FLUX is applied to the product gap by the oil dryer 110, the FLUX (solvent) sprayer 120, and the FLUX dryer 130. And joining is performed.

However, in the conventional brazing apparatus as described above, the flux melted in the brazing furnace is accumulated in the conveyor while being cured in the cooling unit provided on one side of the brazing furnace, and when the flux is deposited on the conveyor for a long time, the conveyor is caused by interference with surroundings. There is a problem that is stopped, may cause damage to the entire brazing device when the conveyance of the conveyor.
