Description

technical field [0001] The invention relates to the technical field of silver removal for dielectric filters, in particular to a laser silver removal machine for dielectric filters and an automatic parallel silver removal method thereof. Background technique [0002] In the production process of the dielectric filter, by adjusting the silver layer in the multiple resonant holes on the dielectric filter cavity, the state in the resonant hole and the coupling relationship between the resonant holes can be adjusted, and then the waveform of the dielectric filter according to the design can be realized. to output. The dielectric filter is usually composed of multiple resonant holes, so it is necessary to adjust the silver layer in several to a dozen resonant holes. [0003] At present, the usual way to adjust the resonance hole in the industry is to first fix the dielectric filter on the debugging platform, read the real-time monitoring performance of the dielectric filter thro...

Problems solved by technology

[0004] 1) The removal device for quantitatively removing the silver layer generally adopts mechanical grinding, which essentially controls the back and forth movement of the grinding head through a servo drive device to remove the silver layer. The operation is inconvenient, cumbersome and complicated, and the grinding is unstable. Low precision, high cost and low efficiency;

[0005] 2) Using the serial adjustment method, a single channel of the vector network analyzer can only adjust one dielectric filter at a time, that is, when the removal device removes the silver layer on the surface of one of the resonant holes, the network analyzer is in an idle state, and only one adjustment is completely completed After that, the next time can be started, resulting in low work efficiency, high energy consumption, and high cost
