Embodiment 1

[0060] S1: Partitioning treatment: After partitioning the foil strip 1 with the separator 102, the foil strip 1 is cut.

[0061] S2: Fixing treatment: one end of the cut foil strip 1 coated with the spacer 102 is arranged at intervals and fixed on the side of the strip 504; the foil strip 1 is fixed in parallel with the strip 504; A gap is left between the opposite surfaces, and the edge of the handle bar 504 is exposed from the end away from the end coated with the spacer glue 102 .

[0062] S3: Spraying treatment process: the strip 504 will be fixed in the bracket 503 of the spraying mechanism 5; , the spraying area 6 covers the first surface 1011, the second surface 1012 and the side surface 1013 of the foil strip 1; the number of sprays is set to 1; the air pressure of the first spray head 501 and the second spray head 502 is 0.4MP6, so The speed of the described spraying mechanism 5 moving along the bar 504 is 10 cm / s. And start the spraying mechanism 5 to spray silver ...

Abstract

The invention relates to a silver paste spraying process of a novel capacitor laminated pole piece. The silver paste spraying process comprises the following steps: S1, zoning treatment: coating a chaff with insulating glue for zoning and then cutting the chaff, S2, fixing treatment: fixing the cut chaff on a handle strip, and S3, spraying treatment process: fixing the handle strip in a bracket of a spraying mechanism; silver paste spraying is conducted on the first surface, the second surface and the side surface of the chaff at the same time; and the silver paste coating with uniform and flat thickness is formed on the surface of the sprayed chaff and is integrated with the chaff. And S4, drying treatment is conducted, specifically, the sprayed chaff silver paste coating is dried, and the silver paste coating with the expected thickness can be obtained. Quantitative spraying is carried out on the surface of the chaff, so that the coating performance of the silver paste coating is higher, the corners are coated, the pole piece with the uniform coating thickness is obtained, the silver-sprayed coating is thin, multiple pole pieces can be stacked, the pole pieces make full contact with one another, the use amount of materials and the stacking thickness are reduced, meanwhile, the ESR performance is more excellent, and the capacity is improved.

Description

technical field [0001] The invention belongs to the field of capacitor manufacturing, in particular to a silver paste spraying process for a novel capacitor laminated pole piece. Background technique [0002] As modern electronic products put forward higher requirements in terms of miniaturization, portability, and high reliability, the precision of capacitors is extremely high, and the manufacturing process of capacitors also needs to be continuously improved to adapt to the integration of electronic equipment. Machines are miniaturized. The multilayer capacitor core is mainly composed of several pole pieces stacked by silver paste, and the surface flatness of each stack and the thickness of the silver paste need to be strictly and precisely controlled. The existing process is to directly soak the pole piece in the silver paste for a period of time and take it out. Because on the one hand, the amount of the silver paste is too much to control the content of the silver past...
