Embodiment

[0040] This embodiment discloses a pre-cutting process of a network filter, which is mainly used in the winding process of the network filter, and is used to cut each lead-out enameled wire of the network filter before winding, so that it can be cut in the following During the winding process, the excess wire ends can be removed more conveniently.

[0041] The process in this embodiment is mainly to use the cutting module to cut the enameled wire of the network filter to form a cut with a cutting depth not greater than 45%. The position of the cut is adjusted according to actual needs to ensure that there is enough surplus material to form a coil. Then the network filter with the slit is sent into the winding process to form a coil on the structure of the outer winding head 11, and after the coil is formed, it is disconnected from the slit, and the coil falls to the inner end of the corresponding pin, This automatically removes excess threads.

[0042] Further, since the tech...

Abstract

The invention belongs to the technical field of network filter winding equipment, and discloses a pre-cutting process of a network filter, which is used for cutting an enameled wire before the enameled wire of the network filter is wound, cutting the enameled wire led out of the network filter through a cutting module, determining a cutting area of the enameled wire, and cutting the enameled wire through a cutting module. At least one notch with the cutting depth not smaller than 45% of the diameter of the enameled wire is formed in the cutting area. According to the invention, the notch meeting the requirement is formed firstly, so that the coil which is wound outside to form the enameled wire can be automatically cut off from the notch after falling into the corresponding pin in the subsequent winding treatment process, and the effect of automatically removing the wire end 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 process of a network filter. Background technique [0002] The function of the filter is to allow a certain part of the frequency signal to pass smoothly, while the other part of the frequency signal is greatly suppressed, it is essentially a frequency selection circuit. In the filter, the frequency range that the signal can pass through is called the passband or passband; on the contrary, the frequency range where the signal is greatly attenuated or completely suppressed is called the stopband; the boundary frequency between the passband and the stopband is called the stopband. is the cut-off 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 the stopband of the actual fil...
