Description
Technical field
The present invention relates to metallic film capacitor field, more particularly to a kind of metal spraying side of metallic film capacitor
Method.
Background technology
In the manufacture method of traditional metallic film capacitor, it is common practice to by two panels metallized film phase
Pair and wind, after making winding film with core, extract core out, then hot pressing then carries out metal spraying to two end faces of fuse,
Electrode lead-out part is re-formed, so as to produce thin film capacitor sub-prime.For metallic film capacitor, evaporated film and
The adhesive strength of outside extraction electrode (metal spraying) is the galvanic key factor of influence.When evaporated film and outside extraction electrode
When adhesive strength is weaker, the loss of capacitor can be caused big, tan δ and ESR increase, so as to cause heating big.
Metallic film capacitor fuse after winding, lamination, its end face usually collapses due to the stress of film metal spraying
(deformation downwards), produces shadow portion, according to conventional way, subsequently still can carry out metal spraying by horizontal direction to fuse end face, due to
Film metal spraying collapses and produces shadow portion, metal spraying can not fully with evaporation metal adherence, so as to influence metallized film capacitor
The performance of device.
The content of the invention
Present invention seek to address that above-mentioned mentioned technical problem, there is provided a kind of metal spraying side of metallic film capacitor
Method.
To reach above-mentioned purpose, technical scheme is as follows：
A kind of metal spraying method of metallic film capacitor, comprises the following steps：
1) after sub-prime is wound, thermocompression forming obtains capacitor body；
2) fixed capacity device fuse；
3) spray gun is moved into capacitor body top, the distance between adjustment capacitor body end face and spray gun；
4) spray gun is adjusted, is allowed to form angle with capacitor body end face, metallic film capacitor fuse end face is entered
The oblique metal spraying of row；
5) repeat the above steps 2-4, and another end face to capacitor body carries out metal spraying.
Preferably, step 3) in the distance between capacitor body end face and spray gun determined by the area of capacitor body end face
It is fixed.
Preferably, step 4) in the angle of spray gun and capacitor body end face be 20-40 degree.
Preferably, step 5) in spray gun and capacitor body end face angle by the deformation downwards of capacitor body end face journey
Degree is determined.
Beneficial effects of the present invention：
The influence for being collapsed by film metal spraying and being produced shadow portion is overcome by the way of oblique metal spraying, enables metal spraying more abundant
It is attached to evaporation metal surface, it is ensured that the performance of metallic film capacitor.
