Description

Technical Field

[0001] The invention belongs to the field of equipment manufacturing, and in particular relates to an automated device for filter debugging. Background Art

[0002] Filters can effectively filter out signals of specific frequencies and are widely used in digital communications, 5G base stations, and other fields. During filter production, it is often necessary to adjust the height of the tuning screws to tune the filter to a specific frequency to meet the needs of signals in different bands. Figure 1 The figure shows a typical filter, which has two types of debugging screws: one with only a self-locking screw 93 and the other with a regular screw 91 and a locking nut 92. Currently, the filter debugging process is usually completed manually. The debugging process requires the filter to be connected to the vector network analyzer through a test cable. The screw and nut are manually adjusted using a screwdriver and a nut sleeve. The process requires manual adjustment of the screw height while observing the waveform curve of the vector network analyzer. This requires high skills and operational level of workers. At the same time, batch operations can easily cause worker fatigue, which in turn affects production efficiency and product qualification rate. With the advent of the 5G era, the demand for communication filters is increasing. The shortage of highly skilled workers has led to insufficient product debugging capacity and the continuous increase in labor costs required. There is an urgent need for an automated device that can replace manual debugging and meet the debugging needs of different types of filters. Summary of the Invention
