Problems solved by technology
[0003] The main shortcomings of the existing welding technology are as follows: 1. The guide pin material of the solid capacitor is aluminum wire Φ1.2mm and tinned copper-clad steel wire (cp wire) Φ0.6mm for butt welding, while the traditional guide pin cp wire Φ0.5mm, due to two different diameters of cp wires, the containment area of solder joints of solid capacitor special guide pins is reduced by 1 / 3 compared with that of traditional guide pins, resulting in the tensile strength and bending times of solder joints ≤3.5kg and Number of bending ≤ 8 times
Easy to produce virtual soldering and solder joints falling off
2. The surface of the welding point is rough and irregular, and the diameter of the welding point exceeds the diameter of the aluminum wire by 0.4-0.6mm, which is protruding. During the assembly process of the solid capacitor, the solder joint of the guide pin must pass through the inner hole of the sealing rubber plug. Protruding solder joints can easily strain the inner hole of the rubber plug, resulting in reduced sealing performance
3. During the processing of solid capacitors, the solder joints of the guide pins fall off, causing the solid capacitors to be scrapped.

The invention discloses a guide pin welding device and a guide pin welding method for solid capacitors. An aluminum wire chuck is movable on the upper side, the cp wire chuck and the aluminum wire chuck are located on the same horizontal line, and two air guide pipes are arranged between the cp wire chuck and the aluminum wire chuck, and the frame A signal switch is provided on the inner side of the slider, and the signal switch is located below the slider, and the two air guide branch pipes converge on one air guide main pipe. Beneficial effects of the present invention: the beneficial effects of the present invention are mainly reflected in: the solder spot does not exceed the outer diameter of the high-purity aluminum wire; Smooth to prevent scratches on the inner hole of the rubber plug in the assembly of solid capacitors; the solder joints are strong, and the number of bending times reaches more than 12.
Description
technical field [0001] The invention relates to the technology of special components for solid capacitors, in particular to a special guide pin welding device for solid capacitors and a production method thereof. Background technique [0002] Solid capacitor is a new type of electronic component that has been industrialized in recent years. It is gradually used in the field of electronic information. The technical problem that has plagued manufacturers in the process of industrialization of solid capacitors is the special guide pin. The guide pin is small in size and high in accuracy. High, there are special requirements for solder joints and tensile strength. [0003] The main shortcomings of the existing welding technology are as follows: 1. The guide pin material of the solid capacitor is aluminum wire Φ1.2mm and tinned copper-clad steel wire (cp wire) Φ0.6mm for butt welding, while the traditional guide pin cp wire Φ0.5mm, due to two different diameters of cp wires, the...
