Specific embodiment
Now in conjunction with attached drawing, elaborate to presently preferred embodiments of the present invention.
As shown in Figures 1 to 7, the present invention provides a kind of preferred implementation of the weld seam forming method of plate and frame in mobile phone
Example.
Specifically, with reference to Fig. 1, a kind of weld seam forming method, the weld seam forming method includes the following steps：
Plate 1 in mobile phone is placed in frame 2 by step 11, determines region 3 to be processed；
Step 21 emits high-frequency pulsed lasers towards region 3 to be processed, and it is 1KHz to 100KHz, duty that frequency, which is arranged,
Than being 10% to 100%；
Step 30, until forming suitable weld seam.
Structure is complicated for plate 1 in mobile phone, and the cost for carrying out numerical control processing is very high, then, in order to reduce cost, is replaced using cast aluminium
For aluminium, using mobile phone weight can also be mitigated while cast aluminium；And frame 2, for proof strength, the material used need to be 6063
Aluminium alloy.But cast aluminium and 6063 aluminium alloys are easy to produce crackle using pulse or continuous welding, and the weld seam generated compared with
It greatly, is 0.8mm or so.Therefore, it is necessary to be processed using above-mentioned weld seam forming method, firstly, referring specifically to fig. 6, passing through machine
Plate 1 in mobile phone is manually placed among frame 2 by tool hand, and determines region 3 to be processed by scanning, described to be processed
Region 3 is the end face that plate 1 is contacted with frame 2 in mobile phone；Then, the laser of transmitting is adjusted to high-frequency pulsed lasers, at this point, high
The frequency of frequency pulse laser is 1KHz to 100KHz, and duty ratio is 10% to 100%；After welding processing after a period of time,
Suitable weld seam, and flawless can be formed, stops weld seam and forms processing；Finally, carrying out next step operation again, carries out weld seam and fill out
It is filled with and knife Milling Machining, plate 1 in mobile phone is combined with frame 2.
It should be noted that duty ratio refers in a pulse cycle, conduction time is relative to ratio shared by total time
Example.
Preferably, the frequency of the high-frequency pulsed lasers is 1KHz to 30KHz, and the duty ratio is 10% to 50%.This
0.4mm or less weld width can be obtained in Shi Jinhang processing, and welding penetration is while guaranteeing bead weld up to 1.5mm or more
It can guarantee big fusion penetration, depth-to-width ratio reaches 5 or more, the welding position burn positions such as frame 2 and inner wall battery compartment are avoided, in addition,
The generation of crackle can effectively be inhibited, increase weld strength.
In the present embodiment, with reference to Fig. 2, step 21 specifically includes following steps：
Laser is integrated into high-frequency pulsed lasers by CW modulation by step 211, and the frequency that high-frequency pulsed lasers are arranged is
1KHz to 100KHz, duty ratio are 10% to 100%；
Step 212 emits high-frequency pulsed lasers towards region 3 to be processed.
Wherein, change control mode by updating board and software and be tuned into CW modulating mode, Fig. 7 shows laser and carries out CW
Waveform diagram when modulation, waveform modulated are sinusoidal signal, control laser at this time and are integrated into high-frequency pulsed lasers, make pulse
Out when light between 0.005ms-1ms, in addition, the frequency of setting high-frequency pulsed lasers is 1KHz to 100KHz, duty ratio is
10% to 100%, it is re-directed towards the region to be processed 3 of plate 1 and frame 2 in mobile phone and emits high-frequency pulsed lasers.In this way, can
Heat input is reduced, effectively control crackle, obtained weld seam carries out simultaneously flawless generation after metallographic test；Due to heat input
It reduces, heat distortion amount can be reduced, guarantee that plate 1 will not be deformed with frame 2 in mobile phone；It can be improved weld strength, weld strength
It can reach 100-200kg, guarantee the performance reliability of plate 1 and frame 2 in mobile phone；The width of weld seam can be effectively controlled simultaneously,
It is even more that weld seam can be controlled in 0.3mm or less under maximum conditions.
More specifically, also being followed the steps below simultaneously with reference to Fig. 3 carrying out step 21：
Step 20 emits high-frequency pulsed lasers towards region 3 to be processed, meanwhile, protection gas is blown into towards region 3 to be processed
Body.
When wherein, due to emitting high-frequency pulsed lasers towards region 3 to be processed, high temperature can be generated, therefore, it is necessary to courts simultaneously
It is blown into protective gas to region 3 to be processed, temperature is reduced with this, avoids in mobile phone plate 1 and frame 2 since high temperature damages.It is preferred that
Ground, the protective gas are argon gas.
Further, with reference to Fig. 4, step 11 is further comprising the steps of later：
After plate 1 is placed in frame 2 in step 12, mobile phone, fixed using welding fixture.
Wherein, it when plate 1 is placed in frame 2 in mobile phone, needs to be fixed using welding fixture, prevents subsequent welded
Slit is mobile at plate 1 in mobile phone when processing and frame 2, guarantees welding quality.
Still further, with reference to Fig. 5, it is further comprising the steps of after step 12：
After plate 1 and frame 2 are fixed in step 13, mobile phone, are cleaned, dried.
Wherein, after plate 1 in mobile phone and fixed frame 2, the surface of plate 1 and frame 2 in Rapid Cleaning, dry mobile phone, and
And the contact jaw in emphasis cleaning, dry mobile phone between plate 1 and frame 2, avoid surface impurity from influencing welding quality.
The present invention also provides the preferred embodiments that the weld seam of plate and frame in a kind of mobile phone forms device.
Specifically, the weld seam of plate 1 and frame 2 forms device in a kind of mobile phone, and the weld seam forms device and uses institute as above
The weld seam forming method stated, it includes objective table, welding mechanism and processor that the weld seam, which forms device, wherein Fig. 6 is referred to,
Plate 1 in mobile phone is placed in frame 2, and is placed on objective table, the processor determines region 3 to be processed；The processor
It controls welding mechanism and emits high-frequency pulsed lasers towards region 3 to be processed, and high-frequency pulsed lasers are arranged in the processor
Frequency is 1KHz to 100KHz, and duty ratio is 10% to 100%；Until forming suitable weld seam, the processor controls bonding machine
Structure stops transmitting high-frequency pulsed lasers.
Further, it further includes the air blowing for being blown into protective gas towards region 3 to be processed that the weld seam, which forms device,
