Abstract

The utility model relates to a solder station with a radiating device. A platform is provided with more than one group of welding racks which comprise a first rack and a second rack for respectively placing power converter assemblies to be welded, wherein each welding rack is provided with a radiating socket on the second rack; the radiating socket is respectively provided with jacks; at least one radiating fins is arranged at the inner side of the socket; when a circuit board of the power converter and a shell with electrical sheets are respectively placed on the first and second racks, the electrical sheets on the shell are inserted in the radiating socket to form thermal contact with the radiating fin. Accordingly, when the electrical sheets are welded, the radiating area can be increased with the radiating fin so as to avoid deformation at the joint of the electrical sheet and the shell resulting from high temperature.

Description

The welding stage of tool heat abstractor

Technical field

The utility model refers to a kind of welding stage of tool heat abstractor especially about a kind of welding stage.

Background technology

General electronic products roughly comprises circuit board and shell, the power supply changeover device (adapter) of for example a lot of small electric apparatus indispensabilities, promptly as shown in Figure 3, in a shell 80, be provided with a circuit board (this is not shown in the figures), further be provided with two power connecting sheets 81 on this shell 80 as attaching plug, for being plugged in the supply socket, two power connecting sheets, 81 medial extremitys also see through welding manner and are electrically connected with the circuit board formation.Because shell 80 generally is made of plastic material, and this power connecting sheet 81 with shell 80 ejection formations after the beginning carry out weld job, and welding the time applies the high temperature that gives on the power connecting sheet 81 and may make itself and the joint melting deformation of shell 80, so its environment that welds must have the cooling measure of the status avoided generation.

See also shown in Figure 4, for being used for the existing welding stage of aforementioned weld job, this welding stage mainly is to be arranged with plural number weldering frame 70 on a continuous platform, each weldering frame 70 includes one first bin 71 and one second bin 72, wherein first bin 71 is a little more than second bin 72, form a perforation 720 again on second bin 72, and below perforation 720, locate to be provided with a radiating groove 73, be loaded with cooling fluid in the radiating groove 73 as water.

Please cooperate and consult shown in Figure 5ly, wait when carrying out weld job, the shell 80 that order has power connecting sheet 81 is positioned on second bin 72, and makes power connecting sheet 81 pass the perforation 720 on second bin 72 and stretch in the cooling fluid of radiating groove 73.The predetermined circuit boards of being located in the shell 80 82 then are placed on first bin 71, and this circuit board 82 is provided with two leads 820, treat with shell 80 on power connecting sheet 81 weld.And when welding,,, utilize cooling fluid to produce the cooling heat dissipation effect only because power connecting sheet 81 major parts are immersed in the cooling fluid though on power connecting sheet 81, produce high temperature, make the unexpected melting deformation of joint of shell 80 and power connecting sheet 81.

Though the cooling measure on the aforementioned welding stage can prevent shell 80 and be out of shape when weld job, but because this power connecting sheet 81 is soaked in cooling fluid, make power connecting sheet 81 when cooling fluid is taken out,, and back end test is caused puzzlement or electrical characteristic is produced harmful effect residual a little cooling fluid.

Summary of the invention

Therefore the utility model main purpose is at the welding stage that a kind of tool heat abstractor is provided, and the heat abstractor that makes this welding stage have a non-water-cooled makes electronic product when welding stage welds, and can reach radiating effect; In addition, when electronic product carries out back end test, the also unexpected electronic product yield that influences.

For reaching the technological means that aforementioned purpose takes is to make aforementioned welding stage comprise:

One platform, it has a surface;

At least one weldering frame is arranged on the surface of aforementioned platform;

One socket is located at and is respectively welded on the frame, and it has at least one jack;

At least one fin is arranged in the socket and is positioned at the jack inboard.

When the electronic product as power supply changeover device welds on welding stage, its power connecting sheet by with socket in fin constitute and to electrically contact, and provide big area of dissipation to reach the effect of heat radiation indirectly by fin.Owing to this fin after power supply changeover device is finished welding promptly with its on power connecting sheet break away from fully do not have any residual, so when back end test, can not cause operation puzzlement or harmful effect.

The specific embodiment

See also shown in Figure 1ly, be 10 1 preferred embodiments of the utility model welding stage, mainly comprise a platform 20, at least one weldering frame 30, a Radiating socket 40, and at least one groups of fins 50 as shown in Figure 2.

This platform 20 is strip, and it has a surface;

Each welds frame 30 and is arranged on the surface of platform 20, it comprises first,

second bin

31,32, and this first bin 31 is formed by plural L shaped bracing frame 311, and each bracing frame 311 with suitable distance alternately, this second bin 32 is continuous shape, for Radiating socket 40 is installed;

Please cooperate and consult shown in Figure 2ly, have one group of jack 41 on this Radiating socket 40, and in the jack 41 inboard accommodation spaces 42 that form, this accommodation space 42 is for ccontaining groups of fins 50;

In the present embodiment, this groups of fins 50 comprises two first fin 51 and two second fin 52, its two be located at jack 41 inboards on the Radiating socket 40 in couples, wherein first fin 51 is generally S-shaped, two second fin 52 link to each other with an end and take the shape of the letter U.

When aforementioned welding stage 10 is used for that power supply changeover device carried out weld job, earlier two power connecting sheets 81 on its shell 80 are inserted in two jacks 41 on the Radiating socket 40, and constitute thermo-contacts with the groups of fins 50 of jack 41 inboards, make the circuit board 82 of power supply changeover device be positioned on first bin 31 again.

And when each power connecting sheet 81 welded, its heat energy will conduct on the fin 50 via power connecting sheet 81, and utilizes this fin 50 to dispel the heat, and is out of shape because of welding high temperature to avoid power connecting sheet 81 and shell 80 joints.

Utilize the design of aforementioned welding stage except that can be to the device radiation that carries out weld job, owing to take the heat dissipation design of non-water-cooled, event is unexpected to cause the operation puzzlement or the harmful effect of back end test because of residual moisture after welding finishes, so possessed outstanding technical characterictic and obvious progress.
