summary of the invention:
In order to overcome the deficiencies in the prior art, provide a kind of contact resistance little, large by electric current, connect more more reliable, electrolytic capacitor laser soldering device and the method for work thereof of product longer service life.
The purpose of this utility model is achieved through the following technical solutions: a kind of electrolytic capacitor laser soldering device, comprise rotating disk and laser weld transmitting tube, be connected with laser weld transmitting tube and spinning apparatus in the upper end of rotating disk, on rotating disk, be provided with many core assemblies bag positioning seat and cover plate bolt positioning seat, on cover plate bolt positioning seat, be arranged with two locating holes, locating hole is corresponding with the exit bolt on cover plate, and cover plate bolt positioning seat is in the outside of core bag positioning seat, spinning apparatus comprises lower air cylinder and banking stop, on banking stop, have spacing hole, on lower air cylinder, be connected with spinning bar, spinning bar is through spacing hole, the straight warp of spinning bar is 8-12mm, spinning masthead end is indent circle, its recessed degree of depth 2-4mm, recessed circle is directly through 4-6mm, when work, be swing rotary pressurization, pendulum angle is 10 ~ 30 degree.
The utility model compared with prior art has following characteristics:
1, revolving contact resistance after riveting, laser weld is 0.02-0.05m Ω, less 10 times than original single cold riveting technique;
2,, when the product that revolves riveting, laser weld uses, the capacitor temperature 1-2 DEG C that only rises, than the original single cold riveting product 3-4 DEG C that declined;
3, after the product that revolves riveting, laser weld falls, weld contact resistance variation rate≤0.5% is less 5 times than original single cold riveting technique;
4, the product that revolves riveting, laser weld is after 105 DEG C, 7000 hours life tests, all qualified.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: air cylinder, 7-banking stop, 8-spacing hole, 9-spinning bar, 10-locating hole under 1-rotating disk, 2-laser weld transmitting tube, 3-spinning apparatus, 4-core bag positioning seat, 5-cover plate bolt positioning seat, 6-.
