Description

Technical Field

[0001] The present invention relates to the field of capacitor electrode foils, and particularly to an automatic wave slitting and trimming device for thin film capacitor electrode foils. Background Art

[0002] In thin film capacitors, designing the capacitor electrode foil structure with a wavy edge has many advantages. For example, the wavy edge design can significantly increase the surface area of the electrode foil, thereby increasing the capacitance value of the capacitor. The increase in specific surface area means that more charges can be stored in the same volume, thus improving the performance of the capacitor. The shape of the wavy edge can better disperse the electric field, reducing the situation where the electric field is concentrated at one point, thereby reducing the possibility of partial 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 electrode foil can better withstand vibrations and stress changes. In the prior art, the wave slitting and trimming of the electrode foil are processed in two independent devices. Processing at two workstations not only causes trouble in processing, reduces processing efficiency, but also increases production costs. Summary of the Invention

The third pressing shaft 59 and the fourth pressing shaft 60 are respectively rotatably arranged on the upper and lower sides of the second sliding groove. Both ends of the third pressing shaft 59 and the fourth pressing shaft 60 are connected by a second tension spring 61. The first material receiving shaft 56, the second material receiving shaft 57, and the fourth bending shaft 58 are all rotatably arranged on the frame 1. The material receiving driving component is fixedly arranged on the frame 1 and is used to drive the first material receiving shaft 56 and the second material receiving shaft 57 to rotate. After the electrode foil 18 is output from the trimming assembly, a part of it passes through the fourth bending shaft 58 and then winds around the first material receiving shaft 56, and another part winds around the second material receiving shaft 57 after passing through the fourth bending shaft 58. The material receiving driving component includes a material receiving driving member 62, a main transmission wheel 63, and a sub-transmission wheel 64. The material receiving driving member 62 is fixedly arranged on the frame 1 and its output part is fixedly connected to the main transmission wheel 63. Sub-transmission wheels 64 are fixedly arranged on both the first material receiving shaft 56 and the second material receiving shaft 57 and are in transmission cooperation with the main transmission wheel 63. The material receiving driving member 62 is electrically connected to the control center. Among them, the material receiving driving member 62 is a motor in the prior art, the main transmission wheel 63 and the sub-transmission wheels 64 are all gears, both sub-transmission wheels 64 are meshed with the main transmission wheel 63, the two sub-transmission wheels 64 are the same gears, and the diameters of the first material receiving shaft 56 and the second material receiving shaft 57 are the same. The first material receiving shaft 56, the second material receiving shaft 57, the fourth bending shaft 58, the third pressing shaft 59, and the fourth pressing shaft 60 are all arranged in parallel with the main shaft 4. The material receiving driving member 62 drives the main transmission wheel 63 to rotate, the main transmission wheel 63 drives the two sub-transmission wheels 64 to rotate, and the two sub-transmission wheels 64 respectively drive the first material receiving shaft 56 and the second material receiving shaft 57 to rotate. For example, the electrode foil raw material is cut into four groups by the centering cutter 2 and the mother cutter 3, namely the first group, the second group, the third group, and the fourth group. The first group and the third group are wound around the first material receiving shaft 56, and the second group and the fourth group are wound around the second material receiving shaft 57. Blind holes are provided at the axial centers of both ends of the third pressing shaft 59 and the fourth pressing shaft 60. One ends of the two second tension springs 61 are respectively inserted into the blind holes at both ends of the third pressing shaft 59, and the other ends of the two second tension springs 61 are respectively inserted into the blind holes at both ends of the fourth pressing shaft 60.

[0036] In some embodiments, the electrode foils 18 on the first material receiving shaft 56 and the second material receiving shaft 57 are arranged alternately. Among them, since the two side edges of the electrode foil 18 are wavy after slitting, if a single material receiving shaft is used to wind the electrode foil 18, during the winding process, the electrode foil 18 is stacked layer by layer, and the wavy structures on adjacent two electrode foil rolls will be embedded into each other, resulting in the inability to separate adjacent two electrode foil rolls and causing difficulties in subsequent processing. Therefore, the first material receiving shaft 56 and the second material receiving shaft 57 are provided to separate adjacent two wound electrode foil rolls.
