Description

[0002] In film capacitors, there are many benefits to designing the capacitor pole foil structure into a wavy edge, such as: the wavy edge design can significantly increase the surface area of ​​the pole foil, thereby increasing the capacitance value of the capacitor. The increase in specific surface area means that more charge can be stored in the same volume, thereby improving the performance of the capacitor; the shape of the wavy edge can better disperse the electric field and reduce the concentration of the electric field at one point, thereby reducing the possibility of local discharge, helping to extend the service life of the capacitor and improve its stability; in some applications, the wavy edge design can also provide better mechanical strength and stability, especially in high-frequency and high-voltage environments, the wavy edge pole foil can better withstand vibration and stress changes.

The receiving drive member 62 drives the main transmission wheel 63 to rotate, the main transmission wheel 63 drives the two auxiliary transmission wheels 64 to rotate, and the two auxiliary transmission wheels 64 respectively drive the first receiving shaft 56 and the second receiving shaft 57 to rotate. For example, the pole foil raw material is cut into four groups by the centimeter cutter 2 and the female cutter 3, which are group one, group two, group three and group four, respectively. Group one and group three are wound on the first receiving shaft 56, and group two and group four are wound on the second receiving shaft 57. Blind holes are provided on the axis of both ends of the third pressing shaft 59 and the fourth pressing shaft 60, and one end of the two second tension springs 61 is respectively inserted into the blind holes at both ends of the third pressing shaft 59, and the other end of the two second tension springs 61 is respectively inserted into the blind holes at both ends of the fourth pressing shaft 60.

[0026] In some embodiments, the pole foil 18 on the first receiving shaft 56 is arranged alternately with the pole foil 18 on the second receiving shaft 57. Among them, since the two sides of the pole foil 18 are wavy after cutting, if one receiving shaft is used to wind the pole foil 18, during the winding process, the pole foil 18 is stacked layer by layer, and the wavy structures on the two adjacent pole foil rolls will be embedded in each other, which makes it impossible to separate the two adjacent pole foil rolls, making the later processing difficult. Therefore, the first receiving shaft 56 and the second receiving shaft 57 are set to separate the two adjacent received pole foil rolls.
