Packaging device of shell-free capacitor

Abstract

The invention discloses a packaging device for a shell-free capacitor, and belongs to the technical field of thin film capacitor packaging. Comprising a die body, a base and an overflow collector, the die body is supported on the base, a feeding pipe is arranged at one end of the top of the die body in the length direction, the lower end of the feeding pipe extends to the base, a feeding valve is arranged on the feeding pipe, an air inlet pipe and an overflow pipe are arranged at the other end of the top of the die body in the length direction, and the air inlet pipe is connected with an external air source. A pressure increasing valve and a deflation valve are arranged on the air inlet pipe, the overflow pipe is connected to one side of the overflow collector, an air outlet pipe is arranged on the other side, corresponding to the overflow pipe, of the overflow collector, a vacuum valve is arranged on the air outlet pipe, the base comprises a bottom plate and a pair of supporting legs, and a plurality of terminal positioning holes penetrating from the upper surface to the lower surface are formed in the bottom plate. And the height of the supporting leg is greater than the length of the terminal of the capacitor to be packaged. The capacitor filling machine has the advantages that enough compactness can be ensured in the capacitor filling process, the problem that materials cannot be completely filled in the filling process is solved, and the quality of finished capacitors is improved.

Description

technical field [0001] The invention belongs to the technical field of film capacitor packaging, and in particular relates to a packaging device for a caseless capacitor. Background technique [0002] Film capacitors are one of the main passive devices in the power electronics industry. They are favored by users at home and abroad for their non-polarity, high insulation resistance, excellent frequency characteristics, and small dielectric loss. Common such as support, absorption, and filtering Capacitance such as resonance and resonance are film capacitors. The current film capacitors are mainly composed of cores, packaging materials, shells, terminals and insulating materials. With the increase of the power of the power supply, the capacity of the selected capacitor also increases, and often the single-capacity core capacitor can no longer meet the capacity requirements. In order to achieve the withstand voltage, capacity and working current and other indicators of capaci...

AI Technical Summary

Problems solved by technology

In the above structure, since the epoxy material is not only used as the shell of the capacitor, but also directly affects the overall shock resistance / vibration and self-radiation performance of the capacitor, it is required that there should be no air holes during the epoxy filling process, and there must be enough In the process of filling epoxy resin, if the air cannot be completely discharged, the epoxy resin cannot be completely filled, which will affect the performance of the product.
