Abstract
The invention provides a preheating hot wind unit used for a crest welder. A whole preheating box comprises an upper shell body and a lower shell body, the lower shell body is of an inverted-cone shape, a fan is arranged at the bottom of the lower shell body, and the upper shell body is of a symmetric cone body shape. An opening is arranged on the top of the upper shell body. A heating device is arranged inside the preheating box and composed of heat pipes, heat conduction holes and a heat conduction plate, the heat conduction plate is fixedly arranged, a plurality of the heat pipes are arranged inside the heat conduction plate, and a plurality of the heat conduction holes are formed in the heat conduction plate. Heat of the heat pipes is transmitted to cold air blown by the fan and the cold air is fully heated inside the preheating box with upper and lower portions both of a reversed cone body shape and then blown to a PCB which conducts motion at the upper portion to achieve preheating effect. A whole heating process is simple, gas temperature rising is quick, and heating efficiency is high.
Description
Technical field
The present invention relates to a kind of crest welder preheating device, provide a kind of for the preheated hot air unit on crest welder.
Background technology
In wave-soldering, need to carry out preheating after welding PCB (printed circuit board (PCB)) spraying scaling powder, existing preheating method mainly contains two kinds of infrared preheating and hot-air pre-heatings.Hot-air pre-heating is to blow to to-be-welded pieces by the air after heating, and preheating is even and efficient is high.In prior art, the heating process of cold air is slower, causes whole warm slack-off.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of for the preheated hot air unit on crest welder, pass to by the heat with heat pipe the cold wind that fan blows into, and the abundant pcb board of heating after-blow in the motion of top in the preheating cabinet that is up and down the centrum shape reaches the effect of preheating.
To achieve these goals, the technical solution used in the present invention is:
A kind of for the preheated hot air unit on crest welder, whole preheating cabinet is comprised of upper shell 2 and lower house 4, and lower house 4 is the vertebral body shape, bottom provided with fan 1, upper shell is symmetrical centrum shape, opening is arranged at the top, and heater is arranged on preheating cabinet inside, by heat pipe 3, thermal hole 6 and heat-conducting plate 7 form, heat-conducting plate 7 fixed installation, several heat pipes 3 are arranged on heat-conducting plate 7 inside, have several thermal holes 6 on heat-conducting plate 7.
Described thermal hole 6 is through hole.
The present invention compared with prior art, whole heating process is simple, gas heating is fast, the efficiency of heating surface is high.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details.
The invention provides a kind ofly for the preheated hot air unit on crest welder, be mainly used in the preheating of the PCB of crest welder.In the present embodiment, whole preheating cabinet is comprised of upper shell 2 and lower house 4.Lower house 4 is the vertebral body shape, and bottom provided with fan 1, upper shell are symmetrical centrum shape, and opening is arranged at the top.Heater is arranged on preheating cabinet inside, and by heat pipe 3, thermal hole 6 and heat-conducting plate 7 form.Heat-conducting plate 7 fixed installation, several heat pipes 3 are arranged on heat-conducting plate 7 inside, have several thermal holes 6 on heat-conducting plate 7, and thermal hole 6 is through hole.
The direction of motion of whole hot blast as shown by arrows in FIG..Fan 1 blows into preheating cabinet with cold wind, and after heat pipe 3 heating, whole heat-conducting plates 7 heat up, and cold wind is heated to be hot blast after blowing over thermal hole 6, blows to pcb board 5 bottoms by the outlet of upper shell 4 and carries out preheating.
The present invention is simple in structure, and the efficiency of heating surface is high, passes to by the heat with heat pipe 3 cold wind that fan 1 blows into, and the pcb board 5 during fully the heating after-blow is moved to top in the preheating cabinet that is up and down the centrum shape, reaches the effect of preheating.Whole heating process is simple, and gas heating is fast, and the efficiency of heating surface is high.
In a word, the invention provides a kind ofly for the preheated hot air unit on crest welder, can be used for the PCB preheating on various crest welders.
Do not break away from the spirit and scope of the present invention and can make many other changes and remodeling.Should be appreciated that to the invention is not restricted to specific execution mode, scope of the present invention is defined by the following claims.
