Novel fully-automatic scissor type winder for capacitor

Abstract

The invention discloses a novel fully-automatic scissor type winder for a capacitor, which comprises a stepper motor, a synchronous belt of a motor fixing seat, a synchronous belt wheel, a high-density urethane paper feed roller, a paper feed roller seat, a paper feed tensioning steel wheel, a tensioning steel wheel seat, a pressing foil block, a foil feed station, a winding needle, a paper drawing clip and a paper padding device, wherein the paper padding device comprises an electrolytic paper double-rail fixing block, an electrolytic paper double rail, a pair of paper padding scissors and a paper padding support sheet. When the paper padding device is used, the insulation grade between a positive aluminum foil and a negative aluminum foil during working can be improved, and the capability of resisting pressure, temperature and ripples of a capacitor is improved, thus the qualified product yield can be directly improved in production and further the quality and the service life of the product are improved.

Description

technical field [0001] The invention relates to a winding machine device, in particular to a novel full-automatic scissors type winding machine for capacitors. Background technique [0002] In the prior art, the winding machine stretches the upper layer of paper to the set length under the pulling of the paper clip, the rolling needle stretches out the upper layer of paper and places it in the opening of the rolling needle, the initial roll of the rolling needle opens the paper clip, and at the same time presses the foil The block presses the aluminum foil on the foil feeding table, and the foil feeding table moves to send the aluminum foil to the coiling needle in the tangential direction of the roll paper, and bring it into the winding until the element is completed. However, when the aluminum foil is wound, its surface is easily washed, scraped off burrs or foil dust and other impurities, which will reduce or disappear the insulation degree of the electrolytic paper.

Problems solved by technology

However, when the aluminum foil is wound, its surface is easily washed, scraped off burrs or foil dust and other impurities, which will reduce or disappear the insulation degree of the electrolytic paper. Formed by contact and extrusion, which reduces the insulation level between aluminum foils

As a result, the insulation degree of the electrolytic paper is reduced or disappeared, the qualified rate of the product is reduced, waste is caused, and the production cost is virtually increased.

At the same time, there are unforeseen quality hidden dangers, such as inter-electrode burr flashover, leakage, short circuit, and current breakdown when used in high-voltage, high-ripple conditions.
