CN105006363A - Capacitor packet processing technology - Google Patents

Abstract

The present invention discloses a capacitor packet processing technology. The processing technology comprises the following steps of S1 making a plurality of capacitor elements of same specification, wherein each capacitor element is formed by winding an aluminum foil and a polypropylene film; S2 laminating and pressing fitting the plurality of capacitor elements into a packet, and then carrying out a charging test; S3 after the charging test is qualified, putting the packet into a drying room to heat to 40-50 DEG C; S4 carrying out the planar packet soldering on an aluminum foil protrusion part of each heated capacitor element to connect the capacitor elements, and leading out the capacitor elements via the connecting sheets and the conducting wires. The capacitor packet soldered by the processing technology provided by the present invention is good in soldering quality, and does not generate the pseudo soldering easily.

Description

A kind of capacitor body processing technology

Technical field:

The present invention relates to power capacitor field, is specifically a kind of capacitor body processing technology.

Background technology:

Traditional capacitor fuse welding be reel, press-fit, charge after welding again, welding surroundings carries out at normal temperatures, it is also large that polar plate area due to capacitor is also just equivalent to area of dissipation very greatly, the temperature difference is throughout the year also larger, so easily occur that welding temperature is inadequate when welding, especially be winter, in welding process, easily cause the phenomenons such as rosin joint like this.

Summary of the invention:

Technical problem to be solved by this invention is, provide the capacitor body processing technology that a kind of welding quality is good, this processing technology not easily produces rosin joint.

Technical solution of the present invention is, provide a kind of capacitor body processing technology, processing technology comprises the steps,

The first step, makes the capacity cell that multiple specification is identical, and wherein each capacity cell is reeled by aluminium foil and polypropylene film and forms;

Second step, stacks multiple capacity cell and press-fits into a fuse, then carries out charge test;

3rd step, after charge test is qualified, puts into drying room fuse and heats, fuse is warmed to 40 ~ 55 degree;

4th step, is carried out the weldering of plane core and makes it be connected, drawn by brace, wire by the aluminium foil protuberance of each capacity cell after heating.

As preferably, the temperature of fuse is warmed to 50 degree.

After the operations such as fuse winding complete, fuse being put into drying room makes fuse be warmed to 40 ~ 55 degree, then welding effect is carried out fine, especially butt welding cooling water pipe, product successful that inner series element aluminium foil area is larger, not easily there is rosin joint phenomenon, because capacitor plate area is large, the time of energy storage is also long, and in the process of welding, the variations in temperature of fuse is little.

Embodiment:

With regard to embodiment, the invention will be further described below:

A kind of capacitor body processing technology, processing technology comprises the steps,

The first step, makes the capacity cell that multiple specification is identical, and wherein each capacity cell is reeled by aluminium foil and polypropylene film and forms;

Second step, stacks multiple capacity cell and press-fits into a fuse, then carries out charge test;

3rd step, after charge test is qualified, puts into drying room fuse and heats, fuse is warmed to 40 ~ 55 degree, and preferably temperature is 50 degree;

4th step, is carried out the weldering of plane core and makes it be connected, drawn by brace, wire, complete fuse and make by the aluminium foil protuberance of each capacity cell after heating.

The fuse welding quality made by this processing technology is good, not easily occurs rosin joint.

Below only just preferred embodiment of the present invention is described, but can not be interpreted as it is limitations on claims.Every equivalent flow process conversion utilizing specification of the present invention to do, includes within scope of patent protection of the present invention.
