A kind of welding procedure for capacitor lead wireTechnical field
The present invention relates to capacitor lead wire welding technology field, particularly relate to a kind of welding procedure for capacitor lead wire.
Background technology
As shown in Figure 1, the manufacturing of electrolytic capacitor lead-in wire, main employing tin silk by aluminum steel 1 and fine copper tinned wire 3 welded together, then through punch forming be required product, under prior art in welding process, with being installed in the semi-circular recesses of fixed block 4 mostly by fine copper tinned wire 3, and then compress the fit depressions of copper sheet 2 bottom surface with top, and then complete the location of fine copper tinned wire, this kind of operating type, irregular burr can be produced in gap place between upper and lower two grooves after pad is formed, make solder joint mellow and full not, full, can not effectively meet product processing quality requirement.
Summary of the invention
The invention provides and a kind ofly can make the mellow and full full welding procedure of solder joint.
For reaching this object, the present invention by the following technical solutions:
For a welding procedure for capacitor lead wire, comprise the following steps:
1). fine copper tinned wire is penetrated in the cavity for the ceramic conduit of capacitor lead wire welding, and make the front end of fine copper tinned wire concordant with the front end of described ceramic conduit, then the ceramic conduit being equipped with fine copper tinned wire is fixed on welding equipment;
2). aluminum steel wire diameter being greater than described fine copper tinned wire is installed on the welding equipment of ceramic conduit front end, and the fine copper tinned wire of the front end of described aluminum steel and described ceramic conduit front end is adjacent to;
3). start welding equipment, weld with described fine copper tinned wire joint place at described aluminum steel.
Wherein, described ceramic conduit runs through along its length and is provided with through hole, and the inner surface of described through hole is provided with the light face being convenient to the feeding of fine copper tinned wire.
Wherein, the incoming line of described through hole is provided with the fillet being convenient to fine copper tinned wire threading.
Wherein, described welding equipment is provided with the feeding mechanism for the feeding of fine copper tinned wire, for the welder of described aluminum steel and the welding of described fine copper tinned wire, and for the shear of the capacitor lead wire fixed length after welding.
Wherein, described welder comprises and is arranged at the described top of ceramic conduit front end and/or the welding gun of below, the adjustable setting of distance between described welding gun muzzle and described ceramic conduit front end.
Wherein, the axis coaxle of described aluminum steel and described fine copper tinned wire is arranged.
Beneficial effect of the present invention: the present invention includes following steps:
1). fine copper tinned wire is penetrated in the cavity for the ceramic conduit of capacitor lead wire welding, and make the front end of fine copper tinned wire concordant with the front end of described ceramic conduit, then the ceramic conduit being equipped with fine copper tinned wire is fixed on welding equipment; 2). aluminum steel wire diameter being greater than described fine copper tinned wire is installed on the welding equipment of ceramic conduit front end, and the fine copper tinned wire of the front end of described aluminum steel and described ceramic conduit front end is adjacent to; 3). start welding equipment, weld with described fine copper tinned wire joint place at described aluminum steel.Said welding method, can form mellow and full full solder joint at the front end place of ceramic conduit, and then meet product processing quality requirement.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing 2.
For a welding procedure for capacitor lead wire, comprise the following steps:
1). fine copper tinned wire 3 is penetrated in the cavity for the ceramic conduit 5 of capacitor lead wire welding, and make the front end of fine copper tinned wire 3 concordant with the front end of described ceramic conduit 5, then the ceramic conduit 5 being equipped with fine copper tinned wire 3 is fixed on welding equipment;
2). the aluminum steel 1 wire diameter being greater than described fine copper tinned wire 3 is installed on the welding equipment of ceramic conduit 5 front end, and the fine copper tinned wire 3 of the front end of described aluminum steel 1 and described ceramic conduit 5 front end is adjacent to;
3). start welding equipment, weld with described fine copper tinned wire 3 joint place at described aluminum steel 1.
Further preferred, described ceramic conduit 5 runs through along its length and is provided with through hole 6, and the inner surface of described through hole 6 is provided with the light face being convenient to fine copper tinned wire 3 feeding.
Preferred further, the incoming line of described through hole 6 is provided with the fillet 61 being convenient to fine copper tinned wire 3 threading.
Further preferred, described welding equipment is provided with the feeding mechanism for fine copper tinned wire 3 feeding, for the welder of described aluminum steel 1 and the welding of described fine copper tinned wire 3, and for the shear of the capacitor lead wire fixed length after welding.
Further preferred, described welder comprises and is arranged at the described top of ceramic conduit 5 front end and/or the welding gun 7 of below, the adjustable setting of distance between described welding gun 7 muzzle and described ceramic conduit 5 front end.
Preferred further, described aluminum steel 1 is arranged with the axis coaxle of described fine copper tinned wire 3.
Adopt above-mentioned processing technology to carry out capacitor lead wire welding, solder joint can be made mellow and full full, and then can effectively ensure product quality requirement, eliminate the burr on solder joint.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
