Abstract

The utility model relates to a soldering bit, which is characterized in that a groove is arranged at the end of a body and two heaters are formed at the end of the body. When in welding operation, a solder wire is disposed in the groove and is melted in the groove after the soldering bit is heated. Influence of external environmental temperature to the groove is small, high temperature can be maintained, and then the soldering bit dose not need frequent heat compensation for welding operation, thereby increasing welding speed while saving energy resources.

Description

Solder horn

Technical field

A kind of solder horn that metal material is melted and carries out weld job that can provide after heating is provided the utility model.

Background technology

Solder horn is an end that is installed in heater, solder horn is improved temperature and the tin silk of contact is melted with heater, can provide electronic component to be welded in printed circuit board (PCB) (printed circuit board; PCB) on, see also shown in Figure 5, solder horn for prior art, it has a body 50, and the end of this body 50 is tip shape and is formed with two inclined-planes 51, when carrying out weld job, utilize solder horn that the pad on the circuit board is given preheating, an amount of tin silk is contacted with 51 places, an inclined-plane, and the heating iron head makes tin silk fusing to reach welding, solder horn is removed solder joint to finish weld job after finishing welding.

Yet actual weld job has following shortcoming:

1. electronic component Chang Wufa once just is welded on the printed circuit board (PCB) really, and must carry out the secondary repair welding, because weld interval is long, about 2.8 seconds of the time of a point of average welding, printed circuit board (PCB) causes the copper foil circuit of weld to be heated to heave because of the high-temperature soldering of secondary easily and peels off mutually with printed circuit board (PCB) sheet material, thereby produces defective products.

2. be solid-state tin silk and can produce tiny tin sweat(ing) because tin is quick-fried in the melted by heat contacting with the solder horn that is high temperature, tin sweat(ing) splash everywhere is on printed circuit board (PCB), make circuit on the printed circuit board (PCB) phenomenon that is short-circuited easily, influence the quality of product, and also increase the use amount of tin, that on average welds a point at present is about 0.0351 gram with the tin amount.

3. the solder horn that is heated is with its inclined-plane fusing tin silk, because the inclined-plane toward the outer side, is influenced by ambient temperature easily and lowers the temperature, so must continue solder horn is given thermal compensation, just get, and the heating that continues will produce the shortcoming of energy consumption so that the hot iron head is kept required welding high temperature.

Summary of the invention

Because the shortcoming of aforementioned prior art, the purpose of this utility model is to provide a kind of solder horn, by design on a body one groove is arranged, and provides Xi Si can place this groove to heat, and reaches the purpose that promotes speed of welding and save the energy.

For reaching aforesaid purpose, the solder horn that the utility model is designed, it has a body, this body is a block made from metal material, a groove is established in its end, and the front and back ends of this groove is open shape, and the both sides of groove are formed with a heating block respectively.

Described solder horn, wherein a heating block is at the vertical height that vertically highly be higher than another heating block of this long axis of body to the position.

Described solder horn, wherein the end face of this two heating block is the inclined-plane, and the extension line on this inclined-plane is formed with an angle with respect to the center line of this long axis of body to the position.

Described solder horn, wherein the recessed groove face of this groove is the inclined-plane, and the extension line on this inclined-plane is formed with an angle with respect to the center line of this long axis of body to the position.

Described solder horn, wherein the bevel angle of the recessed groove face of this groove is identical with the bevel angle of the end face of heating block.

Described solder horn, wherein this body is an elongated cylinder, this this long axis of body to the center line of position be elongated cylinder major axis to center line.

Solder horn provided by the utility model, advantage that can obtain and effect enhancement comprise at least:

1. be to connect solder joint to have the shortcoming that heat scatters and disappears easily compared to prior art with the body side, body of the present utility model is provided with groove in centre, because high temperature can concentrate on groove, provide the tin silk that places groove can melt and reach the welding purpose fast, the time of a point of average welding can significantly shorten compared to prior art, the copper foil circuit heated time that can avoid weld is long and peel off mutually with printed circuit board (PCB) sheet material, reduce the generation of defective products thus, and because welding efficiency obtains to promote, the required human cost of weld job also can reduce.

2. the tin sweat(ing) of the quick-fried generation of Xi Siyinxi can be subjected to the covering of heating block of body, and not splash everywhere on PCB, effectively prevent the PCB phenomenon that is short-circuited, and owing to can keep full tin in the groove, therefore required less with the tin amount of each welding, what on average weld a point is saving with the tin amount compared to prior art.

3. the solder horn that is heated is with its groove fusing tin silk, because the heating block of groove both sides has screening effect, groove is not subject to the influence of ambient temperature and can keeps required high temperature, so do not need solder horn is given frequent thermal compensation, provides the effect of saving the energy.

The specific embodiment

See also Fig. 1 to shown in Figure 3, solder horn of the present utility model, it has a body 10, this body 10 is a cylinder block made from metal material, preferred embodiment shown in the figure is an elongated cylinder, its end middle position is established radially a groove 11, before this groove 11, the rear end is open shape, and the recessed groove face 111 of groove 11 is the inclined-plane, be the extension line of recessed groove face 111 and body 10 major axis to centreline space be formed with an angle, and be formed with a heating block 12 respectively in groove 11 both sides of

body

10,12A, this two heating block 12, the end face 121 of 12A, 121A also is the inclined-plane, this end face 121, the bevel angle of 121A is identical with the gradient face angle of the recessed groove face 111 of groove 11, and wherein a heating block 12 body 10 major axis to the vertical height that vertically highly is higher than another heating block 12A.

See also shown in Figure 4, body 10 is to be installed in heater 20 1 ends, in actual when carrying out weld job, with the two heating blocks 12 with high low head, 12A is resisted against on the solder joint on printed circuit board (PCB) 30 surfaces, make body 10 can be skewed and the welding personnel handled easily is provided, and groove 11 forms the identical passage in a front and back ends aperture, tin silk 40 is placed this groove 11, heat with 20 pairs of bodies 10 of heater, and then can make tin silk 40 melted by heat and reach electronic component is welded in purpose on the printed circuit board (PCB) 30.

When being heated by body 10, the high temperature of its generation can concentrate on the groove 11 of body 10 central authorities, provide the tin silk 40 in the groove 11 to melt fast, to shorten weld interval and to promote welding efficiency, the damage of the printed circuit board (PCB) 30 that prevents the high-temperature soldering overlong time and cause, and

heating block

12,12A can completely cut off extraneous air, make the heat energy dissipation degree reduction of groove 11 and be maintained required high temperature, so do not need body 10 is given frequent thermal compensation, and have an effect of saving the energy, tin silk 40 can be subjected to heating block 12 because of the tin sweat(ing) of the quick-fried generation of tin in addition, and 12A's covers, and splash everywhere is not on printed circuit board (PCB) 30, effectively prevent printed circuit board (PCB) 30 phenomenon that is short-circuited, provide the quality of product can be more stable.
