Pin winding pre-cutting system of network filter and pin winding system thereof

Abstract

The invention belongs to the technical field of network filter winding equipment, and discloses a pin winding pre-cutting system of a network filter and a pin winding system thereof, which are used in a pin winding process of the network filter, the pin winding pre-cutting system comprises a cutting module and a fixed end face, the network filter is fixed on the fixed end face, and an enameled wire is led out for fixation; the cutting module is manually or automatically controlled to move relative to the fixed end face, and the fixed varnished wire is cut by the cutting module to form a notch not larger than 45% of the diameter of the varnished wire. According to the invention, manual or automatic wire winding and cutting processing of multiple groups of network filters can be realized through the cutting module and the fixed end face, and a notch meeting requirements is formed firstly, so that a coil which is wound outside to form an enameled wire can be automatically cut off from the notch after falling into a corresponding pin in a subsequent wire winding processing process, and the production efficiency is improved. Therefore, the effect of automatically removing the thread residues is achieved.

Description

technical field [0001] The invention belongs to the technical field of network filter manufacturing equipment, and in particular relates to a pre-cutting system of a network filter and a foot winding system thereof. Background technique [0002] The function of the filter is to allow the signal of a certain part of the frequency to pass smoothly, while the signal of the other part of the frequency is greatly suppressed. It is essentially a frequency selection circuit. In the filter, the frequency range in which the signal can pass is called the passband or passband; conversely, the frequency range in which the signal is greatly attenuated or completely suppressed is called the stopband; the boundary frequency between the passband and the stopband is called is the cutoff frequency; the voltage gain of the ideal filter is constant in the passband, and the voltage gain in the stopband is zero; there is a transition band of a certain frequency range between the passband and stop...
