An optimized structure of a small aluminum electrolytic capacitor stack machine

Abstract

The invention discloses an optimized structure of a small aluminum electrolytic capacitor assembly machine, which relates to the technical field of aluminum electrolytic capacitor manufacturing. The invention redesigns the so-called "triple combination structure" in which the original traditional assembly core is wrapped into a rubber cover and reduces the It is a "double combination structure", by sending the core package to the end stroke of the guide pin alignment clamp, the guide pin is directly guided into the rubber cover, and it is coaxial in place in one step, avoiding the displacement of the core package riveting point; On the one hand, by setting the pneumatic mechanical foot pulling device under the rubber cover station plate, the pneumatic foot pulling device can effectively clamp the two guide pins of the core package to make it into a "vertical" state, so that the subsequent actions can be "coaxial". The guide pin enters the rubber cover under the "state", avoiding the "top-heavy" phenomenon of the core package and the guide pin, which may cause the guide pin to be skewed or strained, etc., ensuring that the electrical properties of the solid-state SMD series products are not affected, and at the same time stabilizing the capacitance of the capacitor. performance parameters, greatly improving product quality.

Description

technical field [0001] The invention relates to the technical field of manufacturing aluminum electrolytic capacitors, in particular to an optimized structure of a small aluminum electrolytic capacitor assembly machine. Background technique [0002] With the development of high-speed communication and digital electronic products, the demand for miniaturization and planarization of electronic equipment has spread all over the world; therefore, the development of high-level and high-quality chip electronic components, including small aluminum electrolytic capacitors, is not only in There are requirements on the size of the product, and the electrical performance of the product is also more stringent; at present, in the entire aluminum electrolytic capacitor industry, the structure of the assembly machine in the assembly process of the capacitor manufacturing process will directly affect the electrical performance of the product, especially the solid-state SMD series. Aluminum ...

Problems solved by technology

[0003] Throughout the various assembly machines in the manufacturing process of the international capacitor industry, as well as single-station and multi-station (such as 6-station, 8-station, 12-station, and 16-station, etc.) assembly machines, during the assembly operation The mode of inserting the capacitor core pack into the rubber cover is "step-by-step entry method", among which the "Lifu model" is the most used; according to statistics, the number of "Lifu model" owned by domestic enterprises alone is as high as Tens of thousands of units, because this kind of assembly machine is a "single-station series", so the price is low, so it is widely used in the capacitor industry; however, because the operation mode of this "single-station series" assembly machine is "step-by-step The structure of the assembly machine is the so-called "triple combination structure". There are serious technical defects in the structure of this assembly machine, that is, when the core-wrapped guide pin is inserted into the rubber cover, it is not inserted directly at one time. Multi-step completion; because the depth of the core pack guide pin entering the rubber cover is usually shallow, it is easy to make the core pack and the guide pin unable to maintain 100% "perpendicularity". Therefore, this operation often causes the core pack riveting point to shift. It leads to poor electrical conductivity, such as increased leakage current, and sometimes even causes the riveting point of the core package to fall off and cause the product to fail, which will seriously affect the improvement of product quality
