Pin adjusting mechanism and method for thin-film capacitor

Abstract

The invention relates to the technical field of capacitor production. A pin adjusting mechanism of a thin-film capacitor comprises an adjusting support, a lifting mounting block, a transverse plate, apin adjusting air cylinder, a wedge-shaped ejector block, an elastic push block, a middle block, a pin adjusting block and a stop block. The lifting mounting block is connected into the adjusting support; the transverse plate is installed on the lifting mounting block, a limiting rail is arranged at the upper end of the transverse plate, the wedge-shaped ejector block is movably matched in the limiting rail, and the end of the wedge-shaped ejector block is in a sharp top shape. The telescopic end of the pin adjusting air cylinder is connected with the wedge-shaped ejector block. The elastic push block is located at the lower end of the wedge-shaped ejector block. The elastic push block is in corresponding transmission with the middle block, and the wedge-shaped ejector block is in corresponding transmission with the pin adjusting block; and the middle block is movably connected into the limiting rail. The pin adjusting device has the advantages of being high in pin flattening precision and efficient in pressing action.

Description

technical field [0001] The invention relates to the technical field of capacitor production, in particular to a leg-setting mechanism of a film capacitor. Background technique [0002] Film capacitors use metal foil as an electrode, and it is laminated with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and then wound into a cylindrical capacitor. According to the type of plastic film, it is called polyethylene capacitor (also called Mylar capacitor), polypropylene capacitor (also called PP capacitor), polystyrene capacitor (also called PS capacitor) and polycarbonate capacitor. Film capacitors are excellent capacitors due to their many excellent characteristics. Its main characteristics are as follows: non-polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), and low dielectric loss. Based on the above advantages, film capacitors are widely used in analog circuits. Especially...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to propose a film capacitor leg adjustment mechanism with high pin flatness precision and efficient pressing action in view of the problems in the prior art that the unevenness of the pins of the film capacitor affects the processing accuracy and the steps of pressing the pins are cumbersome.
