Sequence includes putting, electrode closure, welding, electrode opening, taking), electrode is contact type welding with product, each solder joint will be completed
A whole set of action, each solder joint at least want could complete for 1 second；2) consistency of solder joint is of poor quality, and the characteristic of electric resistance welding exists
In：The resistance that welded article body bond pad locations contact with each other is that fever loads, and welded article body phase mutual connection is symmetrically pressed by two electrodes
Discharge high current in short-term after touch, keep contact point exothermic melting and adhesion, during electric resistance welding, top electrode and lower electrode and
The welded article being accessed can all generate resistance, and the welding circuit of series circuit is formed with the purpose resistance to be welded, and weld work(
Rate will be distributed on the resistance other than solder joint, cause between electrode and soldered object sparking, adhesion, purpose pad again rosin joint,
Dry joint has several factors and randomness because generating the resistance other than purpose pad, and can only control to prevent completely, so electric
The solder joint of welding resistance only welds above, and the shape, size, degree of adhesion of solder joint cannot be required to have very high consistency.The present invention adopts
It is welded with Laser Welding, compares traditional electric resistance welding, the advantage is that：1) solder joint speed of welding is fast, and Laser Welding welding is
Contactless light irradiation welding (welding sequence includes putting, welding, taking) a set of action can complete all welderings of batch
Spot welding, puts：It is merely placed in specified larger (such as diameter 20cm) circular scope, as long as all pads are in this circular scope
It is interior, it can once put a batch and want soldering part；Welding：Whole solder joints are once soldered within the scope of this, as long as several milliseconds of each solder joint,
Our production efficiency practice result is 10 times of electric resistance welding or more；2) Laser Welding welding is contactless illumination weldering
Connect, the consistent property amount of solder joint only by：1. light absorptive (identical material identical surface conformance is high) 2. spot sizes of welded article,
The shape of light extraction effect, light extraction time (welding parameter is controlled by laser machine completely, is not influenced by welding circuit, consistency height) solder joint
Shape, size, degree of adhesion are fully controllable, and consistency is high.
As shown in Fig. 2, the upper reed plate 4 with current-limiting resistance is equipped with the mounting hole 35 being fixed on insulation assembly, peace
It fills 35 upside of hole and is equipped with upper reed plate current-limiting resistance R129, upper reed plate current-limiting resistance R129 is correspondingly arranged on adjustment upper reed plate current limliting
The notch 33 of the notch 31 of resistance R1 width and adjustment upper reed plate current-limiting resistance R1 length, 35 downside of mounting hole are equipped with upper reed plate
Current-limiting resistance R230, upper reed plate current-limiting resistance R230 be correspondingly arranged on adjustment upper reed plate current-limiting resistance R2 width notch 32 with
Adjust the notch 34 of upper reed plate current-limiting resistance R2 length.Using such structure setting, by adjusting upper reed plate current-limiting resistance R1
The notch 31 of width and the notch 33 of adjustment upper reed plate current-limiting resistance R1 length are equipped with realization and change upper reed plate current-limiting resistance
The width and length of R129, by adjusting the notch 32 and adjustment upper reed plate current-limiting resistance R2 long of upper reed plate current-limiting resistance R2 width
The notch 34 of degree is equipped with the width and length realized and change upper reed plate current-limiting resistance R230.

In practical application, upper reed plate current-limiting resistance R129 and upper reed plate current-limiting resistance R230 are symmetrical arranged, and resistance is equal, root
According to the law of resistance, (resistance of conductor is directly proportional with its length, i.e., in material and constant cross-sectional area, length is longer, conductor
Resistance is bigger, and the cross-sectional area with it is inversely proportional, i.e., in material and constant length, cross-sectional area is bigger, and resistance is smaller, also with
The resistivity of material of conductor has relationship, this rule is just the law of resistance) upper reed plate current-limiting resistance R129 and upper reed plate current limliting
Resistance R230 is designed to can be by changing the structure of length and width, thick its resistance value of size Control, and operation principle is as follows：
It is assumed that the resistivity of upper reed plate material：ρ=2.4m Ω cm/mm2 (resistivity of material of 1mm2 sectional area 1cm length
It is 2.4m Ω), it is assumed that the electric current by upper reed plate is 10A, the width W121=0.6mm of upper reed plate current-limiting resistance R1, upper reed plate
The thickness T122=0.6mm of current-limiting resistance R1, the length L123=8.75mm of upper reed plate current-limiting resistance R1, since upper reed plate limits
Leakage resistance R1 and upper reed plate current-limiting resistance R2 is symmetrical arranged, and resistance is equal, the width W224=of upper reed plate current-limiting resistance R2
0.6mm, the thickness T225=0.6mm of upper reed plate current-limiting resistance R2, the length L226=8.75mm of upper reed plate current-limiting resistance R2.
According to law of resistance formula R=ρ L/S to the resistance value of R1：
R1=ρ × L1/ (T1 × W1)=2.4m Ω × (8.75 ÷ 10) cm/ (0.6mm × 0.6mm)=5.83m Ω
If the width of upper reed plate current-limiting resistance R1 is widened from 0.6mm to 1.0mm, (other parameters are constant) calculates again
The resistance value of reed current-limiting resistance R1：
R1=ρ × L1/ (T1 × W1)=2.4m Ω × (8.75 ÷ 10) cm/ (0.6mm × 1.0mm)=3.5m Ω (resistance values
Reduce)
Similarly change the thickness of upper reed plate current-limiting resistance R1 (the resistance value inverse ratio of R1 changes)；Change upper reed plate current-limiting resistance R1
The length resistance value direct ratio of R1 (change)
Electrical power calculation formula：P=UI；In pure resistor element circuit, according to Ohm's law U=IR；R=U/I；I=U/R generations
Entering in P=UI can also obtain：P=I2R=U2/R
Electrical power is when calculating R1=5.83m Ω：(145.75mW milliwatt)；Electrical power is when R1=3.5m Ω：
87.5mW (milliwatt)
Conclusion：In the case of constant by electric current, change upper reed plate current-limiting resistance R1's and upper reed plate current-limiting resistance R2
Length and width, thick size, or change material (resistivity), it is attained by upper reed plate current-limiting resistance R1 and the R2 resistances of upper reed plate current-limiting resistance

The resistance value of R1 is calculated according to law of resistance formula R=ρ L/S such as icon dimensioning：
R1=ρ × L1/ (T1 × W1)=3.2m Ω × (3.5 ÷ 10) cm/ (0.2mm × 1.25mm)=4.48m Ω
If the width of lower reed current-limiting resistance R1 is reduced to 0.8mm from 1.25mm, (other parameters are constant) calculates again
The resistance value of R1：
R1=ρ × L1/ (T1 × W1)=3.2m Ω × (3.5 ÷ 10) cm/ (0.2mm × 0.8mm)=(resistance value subtracts 7m Ω
It is small)
Similarly change the thickness of lower reed current-limiting resistance R1；Change the length of lower reed current-limiting resistance R1
Electrical power calculation formula：P=UI；In pure resistor element circuit, according to Ohm's law U=IR；R=U/I；I=U/R generations
Entering in P=UI can also obtain：P=I2R=U2/R
Electrical power is when calculating R1=4.48m Ω：112mW (milliwatt)；Electrical power is when R1=7m Ω：175mW (millis
Watt)

Length and width, thick size, or change material (resistivity), it is attained by lower reed current-limiting resistance R1 and lower reed current-limiting resistance R2 resistances
Value variation controls calorific value and electrothermal calefactive rate at work to reach lower reed current-limiting resistance R1 and lower reed current-limiting resistance R2
