The specific embodiment
Followingly be elaborated to implementing optimal morphology of the present utility model with reference to accompanying drawing.
Fig. 1 is the stereogram of the general structure of the scolder of the 1st embodiment of the present utility model hot blast blowoff 10 (being designated hereinafter simply as " hot blast blowoff ") of handling usefulness.The general structure of hot blast blowoff 10 comprises apparatus main body (station) 47, handle portion 11, blast tube 15, can nozzle 30 be installed at the front end of blast tube 15 as required.Apparatus main body 47 is connected with handle portion 11 usefulness stube cables 45.
Detailed structure is described in detail in the back, and the wind that 10 formation of hot blast blowoff can be sent apparatus main body 47 here is from the structure of the front end ejection of blast tube 15.The heater of the electric power heating that dress use device main body 47 provides in blast tube 15, wind becomes later the hot blast ejection through heating.Use device main body 47 is set, and for example can be adjusted into 23 liters/minute of maximums quantity of wind, 100～500 ℃ of hot blast temperatures.
In Fig. 1, express and utilize hot blast blowoff 10, make solder fusing by means of hot blast, the duty that the electronic component C that tellite P is upward welded takes off.Electronic component C in the figure is the IC chip that electrode protrudes from each limit of the main body of rectangular flat shape.Being under the situation of object with such electronic component C, preferably hot blast is not blown on the main body of electronic component C, and only to the electrode blowing hot-air.Under such situation, preferably as shown in the figure, nozzle 30 is installed at the front end of blast tube 15.At the front end of nozzle 30, be provided with along the front port 35 on each limit of electronic component C, from the structure of these front port 35 ejection hot blasts.
Fig. 2 is the cross-section front view of handle portion 11 and nozzle 30.Again, Fig. 3 is the exploded perspective view of handle portion 11 and blast tube 15.
Like this, form the structure that the wind passage sprays from hot air blow port 18 in the device that wind forms by the inside by the inside of stube cable 45, handle portion 11 and blast tube 15.
At the base end side of handle portion 11, the 1st, the 2nd cable connecting part 19a, 19b are set, stube cable 45.
Nozzle 30 is mainly by constituting at the nozzle body that is roughly the round-ended cylinder shape 31 of front enlarged-diameter and at the front port 35 that the front end of nozzle body 31 forms.Form on the base end side of nozzle body 31 and can utilize the flexible portion 32 that screw 33 expansions or diameter reduction are installed.
The internal diameter of the base end side of nozzle 30 is substantially equal to the external diameter of blast tube 15, inserts the front end of blast tube 15 in nozzle body 31, with this nozzle 30 is installed.The structure that the insertion of formation blast tube 15 is stopped by near the stop part 34 of the undergauge direction of principal axis central authorities of nozzle body 31.In case nozzle 30 is installed, because hot air blow port 18 is connected in stop part 34, therefore, stop part 34 becomes the cardinal extremity mouth that receives hot blast from hot air blow port 18.
The front port 35 of present embodiment forms its base end side and is connected in nozzle body 31, and front is along the structure of each limit opening of rectangle.Thereby nozzle body 31 becomes wind passage in the nozzle that is communicated with stop part 34 (cardinal extremity mouth) and front port 35.
Fig. 4 represents wind deflector 20, (a) is its front view, (b) is its vertical view.Wind deflector 20 adopts on discoideus substrate 21, with about 45 ° interval from beginning to form radial joint-cutting 23 near the center, part between the adjacent joint-cutting 23 forms a slice blade 22, and each blade 22 is with respect to the simple structure of substrate 21 with tiltangle (θ among this embodiment=45 °) bending.Blade 22 is made 8.The central part of substrate 21 is provided with medium pore 24.
Action to hot blast blowoff 10 describes below.As the preparation of work, nozzle 30 is installed on blast tube 15 at first.Specifically, send out and screw 33 is installed nozzle 30 is installed on the front end of blast tube 15, fixed at the position tighten the screws 33 that hot air blow port 18 and stop part 34 prop up.
Then, the switch of operator's engaging means main body 47, the temperature with air quantity and hot blast is set on the desirable numerical value simultaneously.The air a (with reference to Fig. 2) of the air quantity of setting leads to the inside of handle 11 by the inside of stube cable 45, further is drawn towards the inside of blast tube 15 again.
On the other hand, the electric power of apparatus main body 47 offers heating portion 16 by electric wire 14.The heat that heating portion 16 takes place offers air a, and therefore, air a forms hot blast h in passing through the process of blast tube 15.The temperature of hot blast h detects in sensor portion 17, and its feedback information is given apparatus main body 47.At apparatus main body 47, at any time the electric power that provides is adjusted, so that the temperature of the 17 detected hot blast h of sensor portion is a design temperature.
Hot blast h by sensor portion 17 is drawn towards wind deflector 20.Shown in Fig. 4 (a), the blade 22 of wind deflector 20 is with respect to the flow direction tilt angle theta (45) of hot blast h, and therefore, hot blast h beats obliquely on fixing blade 22, and its reaction causes air-flow complicated, impels temperature distribution homogenization.In addition, the hot blast h of central part promotes the heat exchange with nozzle body 31 also towards flows outside.That is, nozzle body 31 is heated energetically.
Thereafter hot blast h is by the inside of nozzle body 31, from the front end ejection of front port 35.The hot blast h of ejection concentrates weldering place (scolder handling part) of spraying in the electrode of electronic component C.By the temperature distribution homogenization of hot blast h, scolder melts equably, therefore can take off electronic component C from tellite P rapidly.
Fig. 5 (a) is that expression is arranged at the number of the blade 22 on the wind deflector 20 and the curve map of the relation of the Temperature Distribution of the hot blast h that blows out from hot air blow port 18.Transverse axis is represented to locate, the longitudinal axis represent practical measurement temperature (℃).Respectively locate A, A ', B, B ', C, C ', O is shown in Fig. 5 (b).That is to say, be exactly the O that locates near the center of hot air blow port 18, from the radial arrangement A row of this beginning, B row, C row.Be designated as A ', B ', C ' near the locating of O that locate, be designated as A, B, C away from locating of the O that locates.
Design temperature adopts 500 ℃, and air quantity adopts 20 liters/minute.The number of preparing blade 22 is that 7 kinds of wind deflectors 20 of 4～10 are as sample.The inclination angle of blade 22 is all adopted 45 °.The prior art product of having prepared not to be provided with wind deflector 20 again is sample as a comparison.
With these eight kinds of results that sample is tested, obtain the result shown in the curve of Fig. 5 (a).Under the situation that does not have wind deflector 20, the temperature deviation that causes because of the difference that locates is 290～620 ℃ (the temperature fluctuation amplitude is 330 ℃), and have under 8 the situation at for example blade 22, the temperature deviation scope is 455～535 ℃ (the temperature fluctuation amplitude is 80 ℃).Lobe numbers is under the situation of other numbers, and the temperature fluctuation amplitude is also all below 80 ℃.According to this result, can confirm that wind deflector has excellent equalizing temperature effect.Particularly when the sheet number of blade 22 is 6～10, Temperature Distribution is for being the good distribution at center with 500 ℃ of design temperatures.
Fig. 6 is the curve map of the relation between the Temperature Distribution of the hot blast h that sprays of inclination angle and the hot air blow port 18 of the expression blade 22 that is arranged at wind deflector 20.Transverse axis represents to measure temperature, the longitudinal axis represent practical measurement temperature (℃).Respectively locate A, A ', B, B ', C, C ', O is as the criterion with Fig. 5 (b).
Design temperature adopts 500 ℃, and air quantity adopts 20 liters/minute.The inclination angle of preparing blade 22 is that 4 kinds of wind deflectors 20 (all being fixed on the blast tube 15) of 30 °, 40 °, 45 °, 60 ° are as sample.Again, prepare the inclination angle and adopt 45 °, and the sample of rotatably wind deflector 20 being supported sample as a comparison.The sheet number average of blade 22 adopts 8.
The result that these 5 kinds of samples are tested obtains curve shown in Figure 6.For example, the inclination angle is under the situation of 45 ° (fixing), and the deviation range of temperature is 455～535 ℃ (the temperature fluctuation amplitude is 80 ℃).Under the situation at other inclinations angle, the temperature fluctuation amplitude also is about 70～80 ℃, but is under 45 ° the situation at the inclination angle, obtains more near being the good result of the distribution at center with 500 ℃ of design temperatures.
And supporting that rotatably the inclination angle is under 45 ° the situation of wind deflector 20, it is 430～550 ℃ (the temperature fluctuation amplitude is 120 ℃) that the deviation range of temperature worsens.And, it all is the stable trend (trend that slowly rise in oriented the right in curve) that increases a little near central temperature more that the structure that wind deflector 20 is fixed can be regarded as, and make the result under the situation of its rotation be, and the temperature height is chaotic, and temperature stability is poor.
Though its reason can not be understood fully, but can think that its reason is, under the situation that wind deflector 20 is fixed, in a single day hot blast h runs into hot blast plate 20 will be subjected to very big reaction, its flow direction has very big change (flowing to the homogenising of complicated promotion Temperature Distribution), still, and under situation about rotatably being supported, the reaction that is subjected to is little, flows to change not quite.
In addition, usually hot blast h exists near the low more trend of temperature outside that contact with outer wall (being blast tube 15 here), but when wind deflector 20 was rotated, this trend significantly presented.That is, the A that locates, the B of the deep O of locating, C place temperature especially reduce.By contrast, fixedly the time, especially the inclination angle of blade 22 is near the structure 45 ° with wind deflector 20, and this trend obviously obtains relaxing.This can think because make the complex flowization of hot blast h by fixing wind deflector 20, and is also fully mobile towards the outside, has promoted the cause with the heat exchange of outer wall.That is, can think initial heating outer wall, be inhibited so near the temperature the outer wall descends.In addition, can think has not had to be used to rotate the energy consumption of wind deflector 20, and this has also played favourable effect.
From the above as can be known, hot blast blowoff 10 is by fixedly installing wind deflector simple in structure 20, though the temperature distribution homogenization that also can seek to make expeditiously hot blast h simple in structure in the path of wind.
