Description

The gas preheating unit of rotating disc type soldering furnace

Technical field

The utility model relates to the soldering furnace structural improvement that is applied in the electronic component weld job, aims to provide a gas preheating unit, can increase the heating power of soldering furnace, and makes the thermal treatment zone of soldering furnace can keep certain high temperature.

Background technology

As shown in Figure 1, be one to be commonly called as the structural representation of tunnel type soldering furnace, its soldering furnace mainly is to be transported with linear fashion in order to transport carbon dish 30 by a conveyer belt 10, and the stroke place that transports that is engaged in conveyer belt 10 is provided with a heating compartment 20 that supplies conveyer belt 10 to pass through, desire to carry out weld job electronic component then be to be fixed on later on the carbon dish 30 at last tin cream, its carbon dish 30 that is loaded with electronic component and tin cream promptly passes through heating compartment 20 via transporting of conveyer belt 10, in order to high temperature action, finish such as SMT via heating compartment 20, SMA, the electronic component weld job of SMB.

Because, the high temperature action that electronic component and tin cream must be subjected to soldering furnace really can weld, so must have the heating compartment 20 of enough heating strokes in order to electronic component and tin cream are heated to required working temperature, electronic component by heating compartment 20 must can make its Welding Structure fixing really again in the cooling through appropriateness in addition, therefore under certain travelling speed, the total length of its conveyer belt 10 must be enough to satisfy the time that electronic component is stopped by heating compartment 20, and still must continue to rest on the cooling time on the conveyer belt 10 after electronic component is by heating compartment 20.

Only, under the limited processing operating environment in space, the heating compartment 20 of long distance and the equipment of the conveyer belt 10 great space that will account for, and be unfavorable for the space planning of processing environment, if and prolong in the mode that slows down travelling speed between the heating of 20 pairs of electronic components of heating compartment, the production capacity of integral solder operation will be reduced, and its carbon dish quantity that rests on the conveyer belt 10 also increases relatively, more will cause excessive cost expenditure; Moreover, when electronic component passes through heating compartment 20, contain part special metal (as: copper) on the carbon dish 30 because of electronic component and tin cream, in being heated to pyroprocess, can produce oxidation reaction, so generally can feed gas, as: nitrogen, to produce oxidation resistant effect; Only, generally the device of logical people's nitrogen there is no the surface that is sprayed directly on electronic component through preheating, and the temperature that can slightly reduce heating compartment 20 reduces heating power simultaneously.
