Technical Field

The invention relates to the technical field of winding machines, in particular to a winding machine capable of realizing multistage online impregnation and a capacitor manufacturing method.

Background

In any capacitor that uses a winding process and needs to be impregnated with an electrolyte, particularly in the production of a liquid, solid or gel capacitor, the impregnation needs an electrolyte, but the impregnation requires pressure, usually a negative pressure and a positive pressure alternate cycle, and heating is sometimes required, and even some electrolytes with high viscosity are very difficult to impregnate deep into the micropores of the electrode material, resulting in poor capacitor characteristics.

The wound element is formed by winding an aluminum foil and an electrolytic paper with a certain width into a cylinder shape by winding tension, fixing the cylinder shape by glue or adhesive tape, then the electrolyte must be infiltrated into the cylindrical element by positive and negative pressure circulation and auxiliary heating, the requirement on pressure is high, the electrolyte is difficult to quickly permeate to the center of the element and penetrate to the deep of the micropores of the aluminum foil due to the fact that the cylindrical elements are overlapped layer by layer, and the element is wholly soaked in the electrolyte, so that the electrolyte is adhered to the guide pin, therefore, the assembly is required to be cleaned to ensure the weldability of the guide pin on the substrate, and because the cleaning needs to use a cleaning agent, because the components of the electrolyte consist of organic solvent, inorganic or organic carboxylic acid and ammonium salt thereof and various functional additives, the electrolyte can cause long-term damage to the environment or increase the treatment pressure to relevant units even if the electrolyte is an environment-friendly cleaning agent.
