Abstract

The invention discloses a capacitor production equipment and process, which is applied in the field of capacitor production, and solves the problem that the air in the impregnating agent delivery pipeline is not removed when the capacitor is impregnated, and the dye solution produces air bubbles during the impregnating agent transportation process. A technical problem that affects the quality of produced capacitors. The main point of the technical solution is a capacitor production equipment, including a vacuum tank. Buffer tube, there is a pipeline valve at the connection between the buffer tube and the vacuum tank, and the outer wall of the upper end of the buffer tube is connected with a vent pipe, and the upper end of the vent pipe is provided with a vent port, and the diameter of the cross section of the vent pipe increases first and then becomes smaller from bottom to top , the air release pipe is provided with a floating block, the outer wall of the floating block is attached to the inner wall of the lower end of the air release pipe; the technical effect is to ensure the vacuum state in the capacitor and ensure the quality of the produced capacitor.

Description

technical field [0001] The invention relates to the technical field of capacitor production, in particular to a capacitor production equipment and process. Background technique [0002] With the rapid development of the electronic industry, the demand for capacitors is increasing, and the requirements for the quality of capacitors are also getting higher and higher. In the production process of capacitors, vacuum drying and impregnation is the most important and critical process. During the impregnation process, the capacitor needs to be evacuated, and then the impregnating agent is injected through the impregnation port of the capacitor. If the capacitor contains air or steam in the process of dipping, it is easy to generate bubbles in the impregnating agent, which affects the effect of dipping. [0003] The Chinese patent with the existing publication number CN107452509A discloses a production process of an aluminum electrolytic capacitor, including the following contents...
