Abstract
The invention provides a manufacturing method for an aluminum electrolytic capacitor. The manufacturing method is characterized by comprising the following steps of: firstly, conveying a dried element into an onboard vacuum impregnation machine for impregnation, wherein the element is impregnated twice, 11 to 13 seconds each time; secondly, performing dehydration for 1 to 2 seconds; thirdly, performing vaccumizing impregnation for 6 to 10 seconds; fourthly, performing vacuum dehydration twice, 3 to 5 seconds each time; and finally conveying the impregnated element to an assembly machine connected with the onboard vacuum impregnation machine by using a conveyor, and directly assembling the impregnated element, wherein the air pressure of -0.1MPa is realized by the vacuumizing in the vacuumizing impregnation and vacuum dehydration. The manufacturing method for the aluminum electrolytic capacitor has the advantages that: the service life of the aluminum electrolytic capacitor manufactured by the method is prolonged, and the reliability of the aluminum electrolytic capacitor is improved.
Description
Technical field
The present invention relates to the preparation method of the aluminium electrolytic capacitor of a kind of long-life, high reliability, belong to aluminium electrolytic capacitor manufacturing approach technical field.
Background technology
In traditional alminium electrolytic condenser production technology, the core winding is after accomplishing, and (a collection of quantity 8000-10000 does not wait) through oven dry, impregnating process in batches, and then organizes upright assembling.In this traditional handicraft, be example with 10000 of a collection of products, dip time needs 2 hours; The upright installation time of group needs 2-3 hour, and whole process length consuming time, efficient are low, and have very big inconsistency between the product individuality; Especially it is long that the core after the impregnation wraps in the air open-assembly time; Airborne impurity and moisture can pollute the core bag, product quality are brought very big hidden danger, simultaneously; Electrolyte in the core bag has the volatilization of trace, also can cause deterioration, the lost of life of properties of product.
Summary of the invention
The purpose of this invention is to provide a kind of preparation method who improves the aluminium electrolytic capacitor of alminium electrolytic condenser life-span and reliability.
In order to achieve the above object, technical scheme of the present invention has provided a kind of preparation method of aluminium electrolytic capacitor, it is characterized in that, step is: the core bag after drying is accomplished is sent into the vacuum impregnation machine and is carried out impregnation; The impregnation number of times is 2 times, and each time is 11-13 second, takes off liquid subsequently; Taking off the liquid time is 1-2 second, vacuumizes impregnation again, and the time is 6-10 second; Carry out twice vacuum again and take off liquid, each time is 3-5 second, and at last that impregnation is good sub-prime is delivered to directly to organize on the upright machine of the group that is connected with the vacuum impregnation machine through conveyer and stood; Wherein, vacuumize impregnation and vacuum and take off in the liquid, vacuumize and be set at-0.1MPa.
Advantage of the present invention is: through the aluminium electrolytic capacitor that method provided by the invention prepares, its life-span and reliability all are improved.
Embodiment
For making the present invention more obviously understandable, now with a preferred embodiment.
The preparation method of a kind of aluminium electrolytic capacitor provided by the invention, step is: the core bag after drying is accomplished sends into that the vacuum impregnation machine carries out impregnation on the machine, and the impregnation number of times is 2 times; Each time is 12 seconds, takes off liquid subsequently, and taking off the liquid time is 1 second; Vacuumize impregnation again, the time is 8 seconds, carries out twice vacuum again and takes off liquid; Each time is 4 seconds, at last that impregnation is good sub-prime through conveyer deliver to machine on directly group is upright on the upright machine of group that is connected of vacuum impregnation machine, wherein; Vacuumize impregnation and vacuum and take off in the liquid, vacuumize and be set at-0.1MPa.
Empirical tests, in this technology, sub-prime begins to organizing the upright time of accomplishing generally about 90 minutes from last machine impregnation; The traditional handicraft that compares; Single product has begun to the upright time decreased of accomplishing of group about 62% from impregnation, significantly reduced the time that product exposes in air, has reduced the possibility that sub-prime receives contaminating impurity in the air; And the impregnation time between the sub-prime individuality is in full accord, the amount of impregnation electrolyte zero deflection almost between the sub-prime individuality.
Consistency of performance between the product individuality also is improved significantly simultaneously: 500 products are carried out total verification experimental verification, 0.5 ℃ of-1.5 ℃ of scope of surface temperature rise distribution in the temperature rise testing experiment between the alminium electrolytic condenser individuality; In the high-temperature load experimental verification, the shortest product of life of individual has also reached 95% of nominal life, and product reliability and stability improve greatly.
