Capacitor manufacturing device and capacitor manufacturing method

Abstract

A capacitor making apparatus comprises a foil disc, a conducting bar disc, a cold welding mechanism, a conducting bar transfer mechanism, a conducting bar cutting mechanism and a foil pulling mechanism. A foil band on the foil disc successively passes through the cold welding mechanism and the foil pulling mechanism. The conducting bar disc is used for outputting a conducting bar band to the outside world. The conducting bar transfer mechanism is used for clamping the conducting bar band and pulling the conducting bar band to pass through a conducting bar cutting mechanism preset length. The conducting bar cutting mechanism is used for cutting the conducting bar band so that a portion clamped by the conducting bar transfer mechanism forms a conducting bar. The conducting bar transfer mechanism can transfer the conducting bar to the cold welding mechanism so that one end of the conducting bar aligns at a side edge of the foil band. The cold welding mechanism welds the conducting bar on the foil band through pressure. The foil pulling mechanism is used for pulling the foil band to move a preset length after the cold welding mechanism welds the conducting bar on the foil band. By using the capacitor making apparatus, through mechanical loading, conducting bar welding can be performed, production efficiency is high, consistency of produced capacitor products is good and capacitor product quality is increased. The invention also relates to a capacitor making method.

Description

technical field [0001] The invention relates to the technical field of capacitor manufacturing, in particular to a capacitor manufacturing device and a capacitor manufacturing method. Background technique [0002] A capacitor is a device that stores charge and is widely used in modern electronic and electrical equipment. [0003] The main structure of the capacitor includes aluminum foil, electrolytic paper and guide strips (positive and negative electrodes). One end of the guide strip is welded on the aluminum foil, and the aluminum foil and electrolytic paper welded to the guide strip are wound together to form a capacitor element. Before making the capacitor elements, it is necessary to prepare the guide strips, manually cut the guide strips into the required length of the guide strips, then place the guide strips on the foil strip, determine the position to be welded, and finally weld the guide strips on aluminum foil. [0004] However, welding guide bars by manual loa...

AI Technical Summary

Problems solved by technology

[0004] However, welding guide bars by manual loading not only has low production efficiency and high labor intensity, but also the quality cannot be well guaranteed

Moreover, due to the limitation of the characteristics of the guide bar itself (long bar length, narrow width, and thin thickness), the guide bar is prone to bending and deformation during the feeding process, which affects the production of subsequent capacitors.
