Capacitor element winding device and capacitor element winding method

Abstract

The capacitor element winding device of the present invention includes a first needle winding shaft, a second needle winding shaft, a first driving mechanism and a second driving mechanism. The first needle roller shaft and the second needle roller shaft are coaxial and oppositely arranged, and the end of the first needle roller shaft close to the second needle roller shaft is provided with a first needle roller toward the second needle roller shaft, and the second needle roller shaft The end of the first needle shaft is provided with a second needle towards the first needle shaft, and the first needle and the second needle are close to each other and are used for winding to form a capacitor element. The first drive mechanism drives the first needle roll shaft and the second needle roll shaft to rotate synchronously, and the second drive mechanism drives the first needle roll shaft and the second needle roll shaft to move closer to or move away from each other. It can avoid the deformation of the capacitor element caused by the winding device of the capacitor element when drawing the needle, reduce the gap between the aluminum foils of the capacitor element, improve the quality of the capacitor element product, and reduce the waste of materials. The invention also relates to a capacitor element winding method.

Description

technical field [0001] The invention relates to a capacitor production device, in particular to a capacitor element winding device and a capacitor element winding method. Background technique [0002] A capacitor is a device that stores charge and is widely used in modern electronic and electrical equipment. The main structure of the capacitor includes a capacitor element formed by winding aluminum foil, electrolytic paper and a guide pin. [0003] figure 1 It is a structural schematic diagram of an existing capacitor element winding device. figure 2 It is a structural schematic diagram of a winding needle of an existing capacitor element winding device. like figure 1 and figure 2 As shown, the capacitor element winding device 20 includes a needle winding shaft 22 , a first driving mechanism 24 and a second driving mechanism 26 . The needle winding shaft 22 includes a needle winding rod 222 and a winding needle 223 connected to the end of the needle winding rod 222. ...

Problems solved by technology

However, when the winding needle 223 of the capacitor element winding device 20 is extracted from the capacitor element, since the first winding needle arm 224 and the second winding needle arm 225 of the winding needle 223 are tightly wound together with the aluminum foil and the electrolytic paper, There will be relatively large frictional force between the first needle winding arm 224 and the second needle winding arm 225 and the aluminum foil and the electrolytic paper. 225 is easy to take out a part of the aluminum foil or electrolytic paper to deform the capacitor element, especially when making a element with a width of 20-30mm, the winding needle 223 of the capacitor element winding device 20 is easier to take out a part of the aluminum foil or electrolytic paper , so that the quality of the produced capacitor element is reduced, resulting in a waste of materials

Moreover, when the winding needle shaft 22 of the capacitor element winding device 20 rotates at a high speed, the first winding needle arm 224 and the second winding needle arm 225 will bend due to inertia, and then a gap will be generated between the aluminum foils of the capacitor element, reducing the capacity of the capacitor.
