Abstract
The utility model discloses a square hot gas welding tip, which is provided with a wind gun joint. The clamp nut is arranged on the top of and outside wind gun joint, and the bottom of the wind gun joint is connected with the upside of the bell mouth for dispelling wind. A sealing board is arranged at the bottom of the bell mouth for dispelling wind. The technical proposal: a square outlet air hole is arranged in the middle of the sealing board of the bell mouth, and the boarding which is changed into square passage is arranged at the bottom of the sealing board. In addition, a square passage is connected with the outlet air hole. The utility model overcomes the shortcomings in prior art, such as the asymmetric heating, high cost and low welding quality, and provides a square hot gas welding tip with simple structure, low cost, symmetrical heating, and perfect welding effect.
Description
[technical field]
The utility model relates to a kind of noncontact welder, a kind of hot blast tip of more specifically saying so.
[background technology]
At present, when using hot blast welding machine welding CPU or IC in the industry, all be directly to blow facing to CPU or IC with welding gun, because CPU or IC are square, and welding gun is circular, will cause CPU or the IC piece inequality of being heated like this, the not good and thermal waste of welding effect, heat time heating time is long, need could guarantee welding quality than CPU or the more heavy in section air pressure gun of IC area, cause hot blast welding product production cost height, welding quality is not good.
[summary of the invention]
The utility model purpose is to have overcome the inequality of being heated in the prior art, the production cost height, the deficiency that welding quality is not good, provide a kind of simple in structure, production cost is low, be heated evenly, square hot blast tip that welding effect is better.
The utility model is achieved through the following technical solutions:
A kind of square hot blast tip, comprise the air pressure gun joint, the air pressure gun upper end of joint outside is provided with clamp nut, air pressure gun joint lower end is connected with diffusing air horn mouth upper end, diffusing air horn mouth lower end is provided with the horn mouth hush panel, it is characterized in that being provided with a square exhaust vent in the middle of the horn mouth hush panel, be provided with the coaming plate that surrounds square duct in the lower end of hush panel, square duct and exhaust vent connect;
Aforesaid a kind of square hot blast tip is characterized in that described exhaust vent 401 is the square opening corresponding with IC;
Aforesaid a kind of square hot blast tip, it is characterized in that described coaming plate 5 be by two L type thin plates be buckled into square;
Aforesaid a kind of square hot blast tip, it is characterized in that described coaming plate 5 be by two U type thin plates be buckled into square;
Aforesaid a kind of square hot blast tip, it is characterized in that described coaming plate 5 be by a thin plate surround square.
The utility model has following advantage:
1, simple in structure, air-out passway shape is consistent with the welded part shape, reduces heated time, and production cost is low;
2, be heated evenly, the welding foot effect is better.

Fig. 2 is a upward view of the present utility model;
Fig. 3 is a side view of the present utility model;
Fig. 4 is a cutaway view of the present utility model.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
A kind of square hot blast tip, comprise air pressure gun joint 1, the outside, air pressure gun joint 1 upper end is provided with clamp nut 2, be used for being connected of fastening air pressure gun joint and air pressure gun, air pressure gun joint 1 lower end is connected with diffusing air horn mouth 3 upper ends, the air horn mouth 3 that looses is used for spreading the hot blast that comes out from air pressure gun joint 1, diffusing air horn mouth 3 lower ends are provided with horn mouth hush panel 4, be provided with a square exhaust vent 401 in the middle of the horn mouth hush panel 4, be provided with the coaming plate 5 that surrounds square duct in the lower end of hush panel 4, square duct and exhaust vent 401 connect.Described exhaust vent 401 is the square opening corresponding with IC.Described coaming plate 5 be by two L types or U type thin plate be buckled into square, or by a thin plate surround square.
When using the utility model to carry out the noncontact welding, square hot blast tip is connected on the air pressure gun of hot blast welding machine, air-flow comes out from air pressure gun, enter the air pressure gun joint 1 of hot blast tip, by the air horn mouth 3 that looses with thermal current diffusion back in the square duct that is filled in coaming plate 5 after the exhaust vent 401 of horn mouth hush panel 4 flows out and surrounds, square duct faces CPU or the IC piece that is placed on the circuit board, hot blast comes out to face to blow on CPU or the IC piece from square duct, and CPU or IC piece promptly all can be soldered on the circuit board.
