Further, described laser generator is 532nm laser instrument.
Further, described beam expanding lens is 5 power beam expansion lens, and the described aperture of the diaphragm is 2mm, and described F-Theta field lens focal length is 254mm.
It is a kind of for welding the laser tin-soldering device of mobile phone camera that the utility model provides, by laser generator emission pulse laser process beam expanding lens, diaphragm, laser galvanometer and F-Theta field lens arrive processing platform and carry out scolding tin, the time of a scolding tin is divided into a plurality of time periods that connect successively, by described PWM modulation circuit, adjust the dutycycle of described laser pulse, laser pulse dutycycle in each time period remains unchanged, the dutycycle of the laser pulse that different time sections is corresponding increases gradually, thereby simulate a discrete scolding tin curve from low temperature to high temperature, the temperature for the treatment of solder(ing) paste is increased gradually, in the situation that guarantee mean power and the constant peak power that reduces laser of frequency of laser, thereby also reduced the power density at processing place laser facula, effectively prevented because temperature excursion causes tin cream to splash the problem with the scald of non-weld.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 for the utility model embodiment provide a kind of for welding the structural representation of the laser tin-soldering device of mobile phone camera.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, it is a kind of for welding the laser tin-soldering device of mobile phone camera that the utility model embodiment provides, comprise laser generator 1, be arranged on the beam expanding lens 2 of described laser generator 1 output, be arranged on the diaphragm 3 of described beam expanding lens 2 outputs, be arranged on the laser galvanometer 4 of described diaphragm 3 outputs, be arranged on the F-Theta field lens 5 of described laser galvanometer 4 outputs and the PWM modulation circuit being connected with described laser generator 1, described F-Theta field lens 5 is right against processing platform 6, in preferred embodiment of the present utility model, described laser generator 1 is 532nm end pumping coupling fiber solid state laser, the pulse width of Output of laser is nanosecond, it is a kind of for welding the laser tin-soldering device of mobile phone camera that the utility model provides, by laser generator 1 emission pulse laser, through beam expanding lens 2, diaphragm 3, laser galvanometer 4 and F-Theta field lens 5, arrive processing platform 6 and carry out scolding tin, laser scolding tin device structure of the present utility model is simple, and cost is low.
A kind of for welding the embodiment of the laser tin-soldering device of mobile phone camera at the utility model, described processing platform 6 is in positive out of focus position, can be by adjusting the distance between whole laser tin-soldering device and processing platform 6, adjust the distance between F-Theta field lens 5 and processing platform 6, the top of the focus that makes laser in processing platform 6, it is positive out of focus, adopt positive out of focus, make laser spot outside soldered tin cream, the laser power density at soldered like this tin cream place is also relatively little, the phenomenon of having avoided tin cream variations in temperature acutely to splash.
Further, described beam expanding lens 2 is 5 power beam expansion lens 2, and described diaphragm 3 apertures are 2mm left and right, and described F-Theta field lens 5 focal lengths are 254mm.
It is a kind of for welding the method for the laser tin-soldering device welding mobile phone camera of mobile phone camera that embodiment of the present utility model provides, and comprising:
Step 1, mobile described laser tin-soldering device to described F-Theta field lens 5 are right against processing platform 6, and a plurality of mobile phone cameras to be welded are housed on described processing platform 6;
Step 2, described laser generator 1 emission pulse laser, described laser passes through described beam expanding lens 2 successively, diaphragm 3, laser galvanometer 4 and F-Theta field lens 5 are got on the mobile phone camera to be welded on processing platform 6, carry out scolding tin, welded a mobile phone camera, by laser galvanometer 4, adjust the position of laser, laser is moved to next mobile phone camera place, carry out scolding tin next time, the time of a scolding tin is generally 350ms, described PWM modulation circuit is adjusted the dutycycle of described laser pulse, one time scolding tin process was comprised of a plurality of time periods that connect successively, the dutycycle of the described laser pulse described in each in time period remains unchanged, in described a plurality of time period, the dutycycle of corresponding described laser pulse increased gradually from first time period to last time period.
