Background technology
The patent of invention of existing Patent No. ZL201110162314.8 discloses a kind of welding method of magnetic coil,
Include the following steps：Magnetic coil with several the end of a thread is provided；Electric connecting part equipped with several conduction regions is provided；There is provided one
Radium-shine laser equipment；One welding equipment is provided；The end of a thread is aligned one by one with conduction region, the end of a thread one section of definition corresponding with conduction region
For welding section, the coat of paint of the radium-shine laser equipment removal welding section；The welding section of the end of a thread is welded in using welding equipment and is led
In electric area.Due in advance removing welding section coat of paint, in final welding process, welding section is not susceptible to deformation, to ensure
The end of a thread good tensile strength.But surface labeling type electronic element need to usually be heated through reflow soldering, therefore this method
In the presence of the unreliable hidden danger of welding：After welding need in further brush tin on solder joint, if soldered magnetic coil is heated again,
After tin can be heated to melt to be flowed around, there is even tin short circuit hidden danger between adjacent welds, also, tin is lost in, it is welded on conduction region
The end of a thread be easy detached with conduction region due to own tension, so as to cause product open a way；If after welding, brush tin, solder joint be not reliable
Property it is low, the end of a thread be easy from conduction region be detached from.
Invention content
For overcome the deficiencies in the prior art, it is high, still reliable through solder joint when high temperature to provide a kind of production efficiency by the present invention
Magnetic coil welding method.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of magnetic coil welding method, includes the following steps：（a）An insulating base is provided, the insulating base includes
Several side walls and a bottom wall, several side walls and bottom wall form a storage tank, and insulating base is provided with several mutual in side wall
The solder bath separated, further includes several conducting terminals for being fixed on side wall, and the conducting terminal has the weldering for being exposed to solder bath
Connect plane；（b）Holder with an at least fixing groove is provided, the insulating base is fixed on fixing groove；（c）If providing has
The magnetic coil of dry lead, the magnetic coil are contained in storage tank；（d）Lead is placed in solder bath, lead is made to be located at weldering
It connects above plane, it is further comprising the steps of：（e）Lead and welding plane welding are integrated by a plumb joint；（f ）Removal
Positioned at the insulating layer of solder bath wire surface；（g）Solder is added in solder bath, and so that solder is fixed on welding by heating and puts down
Face.
Magnetic coil lead and conducting terminal welding are integrated by the present invention by plumb joint, and can effectively improve solder joint can
By property, melting even if solder joint is heated again, lead will not occur to detach with conducting terminal because of own tension, simultaneously as
Solder is placed in solder bath spaced apart from each other, will not be lost in after the heated thawing of solder, after temperature reduces, be melted around
Solder can solidify again, to ensure that the reliability of solder joint, prevented short circuit and open circuit phenomenon generation, in addition, solder
Curing mode can be used high temperature furnace and be cured, and such as reflow soldering or oven, product can in high volume carry out heating simultaneously makes solder
Admittedly being fixed on welding plane, production efficiency is efficient.

Specific implementation mode
Shown in Fig. 6, a kind of 4 welding method of magnetic coil includes the following steps：One insulating base 1 is provided,
The insulating base 1 includes several side walls 11 and a bottom wall 12, and several side walls 11 and bottom wall 12 form a storage tank 13, absolutely
Edge pedestal 1 is provided with several solder baths spaced apart from each other 14 in side wall 11, and solder bath 14 is spaced from each other by jube 16, further includes
Several conducting terminals 2 of side wall 11 are fixed on, the conducting terminal 2 has the welding plane 21 for being exposed to solder bath 14；It provides
The insulating base 1 is fixed on fixing groove 31 by the holder 3 with an at least fixing groove 31, and a fixation can be arranged in holder 3
Slot 31（Such as Fig. 4）, or multiple fixing grooves 31 are set（Such as Fig. 5）, with improving production efficiency；Magnetism with several leads 41 is provided
Coil 4, the magnetic coil 4 are contained in storage tank 13；Lead 41 is placed in solder bath 14, lead 41 is made to be located at welding plane
21 tops, lead 41 can be fixed by holder 3, or be fixed on external auxiliary jig, further comprising the steps of：Pass through a plumb joint
（It is not shown）Lead 41 and 21 welding of welding plane are integrated, the plumb joint uses high-frequency welder principle, plumb joint tool
There is the tip less than solder bath 14 to heat up by moment when tip is contacted with lead 41, lead 41 is made to be fused to welding plane
21；Insulating layer of the removal positioned at 14 lead of solder bath, 41 surface（Lead 41 is enameled wire, and internal is metallic conductor, surface packet
It has been covered with the coat of paint of insulated barriers effect, insulating layer has been constituted, the insulation can be removed by existing common laser or wicking mode
Layer）；Solder is added in solder bath 14, and so that solder is fixed on welding plane 21 by heating.
