111.The method for processing the first hole 111 includes at least one of Laser Processing, mechanical stamping and machine drilling.As shown in Figure 2 A,
In the present embodiment, the quantity in the first hole 111 is multiple, each first hole 111 be directly to blind hole, the first hole 111
The surface 101 of extending direction and the first metalwork 110 is perpendicular.In other embodiments, the first hole 111 or through-hole.
Multiple first holes 111 can be arranged in circle on the surface 101 of the first metalwork 110 or be arranged in array-like.It is appreciated that
Multiple first holes 111 can also be arranged in other arbitrary shapes.
S102：One second metalwork 120 is fixed on surface 101 of first metalwork 110 with the first hole 111.
As shown in Figure 2 B, the second metalwork 120 being fixed and being pressed on the first metalwork 110 has the table in the first hole 111
On face 101.The material of second metalwork 120 and the first metalwork 110 may be the same or different, the first metalwork 110 and the second gold medal
Belonging to the shape of part 120 can be set according to actual demand.
S103：The position that the first hole 111 is corresponded to the second metalwork 120 carries out laser welding, makes the second metalwork of part
120 melt and fill the first hole 111, and the first metalwork 110 and the second metalwork 120 are riveted.
Referring to Fig. 2 B and 2C, in side of second metalwork 120 far from the first metalwork 110, and first is corresponded to
The position in hole 111 carries out laser welding.Melted by heat is simultaneously under the action of laser for the second metalwork of part 120 at Laser Processing
It is filled into the first hole 111 of the first metalwork 110, forms riveted structure.After the completion of welding, the first metalwork 110 and
Two metalworks 120 are riveted together, and have stronger riveted power between the two.In above-mentioned laser clinching method, bond pad locations
Structural integrity, the molten bath of solder joint is complete, flawless, and clear in structure, and the depth in solder joint molten bath is relatively stable.
It is appreciated that the heat that laser is sent out also is spread on the periphery in the first hole 111, the first hole 111 will be heated gradually to be increased
Greatly, to be effectively increased the pool depth of laser welding.
Referring to Fig. 3 A to Fig. 3 C, laser clinching method and first embodiment in second embodiment of the invention
Similar, difference is：In step S101, at least one first hole 211 is processed on the first metalwork 210, first hole
211 be substantially in reverse V-shaped and the first oblique hole 212 and the second oblique hole 213 including intersecting, and the first oblique hole 212 and second is oblique
Surface 201 to hole 213 with the first metalwork 210 is obliquely installed, and is symmetrically distributed in the both sides of the vertical axis N on surface 201.
When processing the first hole 211, first time Laser Processing is first carried out to the precalculated position of the first metalwork 210, for the first time
The vertical axis N of the incident angle of Laser Processing and the first metalwork 210 deviates certain angle, to be formed and the first metalwork
The first oblique hole 212 that 210 surface 201 is obliquely installed.Then, it carries out second to the precalculated position to laser machine, second
The incident angle of the incident angle of secondary Laser Processing and for the first time Laser Processing is symmetrical relative to vertical axis N, to be formed and the
The second oblique hole 213 that the surface 201 of one metalwork 210 is obliquely installed, the first oblique hole 212 and the second oblique hole 213 are
Intersect on the surface 201 of one metalwork 210, to form the first hole 211.
Then, the second metalwork 220 is fixed on surface 201 of first metalwork 210 with the first hole 211.Then,
The position that the first hole 211 is corresponded to the second metalwork 220 carries out laser welding, and the second metalwork of part 220 is made to melt and fill
First hole 211, the first metalwork 210 and the second metalwork 220 are riveted.
In this second embodiment, since each first hole 211 includes the first oblique hole 212 and the second oblique hole 213,
Second metalwork 220 of fusing will fill the first oblique hole 212 and the second oblique hole 213 respectively, so as to further increase first
Riveted power between 210 and second metalwork 220 of metalwork.
Please refer to Fig. 4, the laser clinching method in third embodiment of the invention is similar to first embodiment, difference
It is：Before laser welding is carried out to the second metalwork 320, on surface of second metalwork 320 far from the first metalwork 310
Upper at least one second hole 321 of processing.In the present embodiment, the quantity in the second hole 321 is multiple, and each second hole 321 is
Through-hole, and it is corresponding with the position in the first hole 311 respectively.It is appreciated that in other embodiments, the second hole 321 is alternatively
Blind hole, and the second hole 321 can be also not correspond to the position in the first hole 311.
In the third embodiment, since the surface of the second metalwork 320 is machined at least one second hole 321, phase
For the laser clinching method of first embodiment, this method can further reduce energy required during laser welding, reduce
The peak value of laser.This method effectively increases the pool depth of laser welding, improves the first metalwork 310 and the second metalwork
Riveted power between 320.
It is appreciated that in other embodiments, shape, quantity and the position in the first hole 111 can be according to the realities of riveting
Border demand is configured.
In addition, those skilled in the art can also do other variations in spirit of the invention, certainly, these are smart according to the present invention
The variation that god is done should be all included in scope of the present invention.
