Abstract

The invention discloses a double-layer packing paper winding mechanism for a capacitor and a winding method of the double-layer packing paper winding mechanism. The mechanism comprises a guide rail device, a shutdown mechanism, a winding mechanism and a paper pulling mechanism, wherein the shutdown mechanism is located at a paper outlet end of the guide rail device; the winding mechanism is located at the paper outlet end of the guide rail device; the guide rail device comprises upper and lower layer double-rail guide rails, and anode and cathode foil guide rails; the upper layer double-rail guide rail is provided with an unwinding prevention clamping device; the upper layer double-rail guide rail and the paper pulling mechanism are located on the two sides of the winding mechanism; paper outlet ends of the anode and cathode foil guide rails are provided with anode and cathode foil feed devices respectively; and a connecting line of the anode and cathode foil guide rails penetrates through the winding mechanism. The method comprises the steps that upper layer isolation paper is introduced; the upper layer isolation paper is pulled to be tangential to a winding shaft; cathode foil, lower layer isolation paper and anode foil are introduced; the winding shaft rotates; the upper layer isolation paper is started to wind; the cathode foil, the lower layer isolation paper and the anode foil are embedded into the upper layer isolation paper to wind together; when guide pin sensors detect guide pins, the upper layer isolation paper, the cathode foil, the lower layer isolation paper and the anode foil are shut down; and winding is stopped. According to the mechanism and the method, the isolation paper can be prevented from being punctured, and a wastage rate (tg delta) and ESR (equivalent series resistance) of the capacitor are reduced, so that the service life of the capacitor is prolonged.

Description

technical field [0001] The invention relates to capacitor winding equipment, in particular to a double-layer spacer paper winding mechanism for double capacitors and a winding method thereof for realizing winding of double-layer spacer paper. Background technique [0002] Capacitors are usually referred to simply as capacitors, which are "charged containers" and are devices that hold charges. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. [0003] Capacitors are essential basic components in electronic equipment and power equipment. They are widely used in audio-visual equipment, computer terminal equipment, communication equipment, energy-saving light sources, automotive electronics, electrical equipment, electronic systems, military products, aerospace and other fields. [0004] The demand for capacitors is incr...
