Description

TECHNICAL FIELD

[0001] The present application relates to the field of capacitor elements, in particular to a winding finishing shaping mechanism of a capacitor element. BACKGROUND

[0002] Capacitor elements are the core part of capacitors, which play important functions such as storing electrical energy, filtering, coupling and many others in electronic circuits. Capacitor element winding refers to the process of winding the electrode plate material (such as metal foil) and the dielectric material (such as plastic film, electrolytic paper, etc.) of the capacitor together in a certain order and manner through a specific device (winding machine) to form a compact capacitor element with a multi-layer structure. This winding structure can effectively increase the electrode plate area and reduce the electrode plate spacing in a limited space, thereby increasing the capacitance of the capacitor.

[0003] After winding is completed, the electrode plate material in the winding needs to be cut off. However, the electrode plate material is supported by tension during winding, and after cutting, it loses external tension support, causing the electrode plate material formed by winding to loosen, which in turn causes a certain gap between the electrode plate materials in the winding, resulting in an increase in the overall diameter of the capacitor element and affecting the winding finishing effect of the capacitor element as a whole.

[0004] In view of the above related technology, the inventor believes that the electrode plate material after cutting has the defect of overall loosening during winding finishing of the capacitor element, and therefore proposes a winding finishing shaping mechanism of a capacitor element to solve the above problems. CONTENT OF THE INVENTION

[0008] Preferably, the clamping mechanism comprises a fixed frame fixedly installed at one side of the movable support, and a clamping plate symmetrically rotatably installed at the upper and lower ends of the inner wall of the fixed frame.

[0009] Preferably, a fixed groove is provided in the middle of one end of the winding processing part, a gear is rotatably installed in the fixed groove, and a guide rack plate is fixedly connected to the inside of the fixed groove.

[0010] Preferably, the guide rack plates are symmetrically arranged at the upper and lower ends of the outer surface of the gear, abut against the outer surface of the gear at one end, and are in mesh with each other.

[0011] Preferably, through holes are provided in the vicinity of the four corners on one side of the movable support, the outer diameter of the fixed support plate is smaller than the inner diameter of the through hole, and the fixed support plate and the through hole are embedded in each other.

[0012] In summary, the present application has the following beneficial technical effects:

[0013] By allowing the movable support to be movably arranged on the outer surface of the fixed support plate under the pulling of the contraction spring, the driving winding roller can be used to wind and process the polar plate material, and when the winding and cutting of the polar plate material is completed, the conical limiting body can be used to movably push the clamping plate to clamp the cutting end of the polar plate material, the contraction spring can be used to pull the connected polar plate material and movable support to be wound and tightened, and the two movable supports can be movably arranged relative to each other under the connection of the gear and the guide rack plate.

The upper and lower ends of the inner wall of the fixed frame 10 are symmetrically and rotatably mounted with clamping plates 11.
