Automatic trimming apparatus for microwave ceramic component semimanufacture and trimming method thereof

Abstract

Provided is a microwave ceramics component semi finished article automatic trimming device and a trimming method thereof, which relates to the adjustment of resonance frequency of the microwave ceramics components, providing a microwave ceramics component semi finished article automatic trimming device and a trimming method thereof which can realize the adjustment process automatization, the real-time detection and storage of the component parameter, and can markedly advance the rate of products meeting standards. The trimming device is arranged with a resonant cavity, a sample conveying device, a baffle, a motor driving and controlling circuit, a vector network analyzer and a laser. The light beam is assembled on the semi finished articles and transmitted between an upper parallel plate and a lower parallel plate; the parameters of the semi finished articles are gathered to the computer, to check whether matching with the finished product requirement compared with the set adjustment parameters, if not, the laser is started to etch the semi finished article. The computer obtains the trimming parameters of the semi finished articles and the set processing parameters to compare, when consistent, the etching is stopped. The processed parameters of the semi finished articles are stored, and the control motor transmits the next semi finished article till the completion of the semi finished article.

Description

technical field [0001] The invention relates to an adjustment of the resonant frequency of a microwave ceramic component, in particular to an automatic fine-tuning device and an automatic fine-tuning method for the resonant frequency of a semi-finished microwave ceramic component. Background technique [0002] Microwave ceramics (or microwave dielectric ceramics, MWDC) refer to ceramics that are used as dielectric materials in microwave frequency bands (mainly UHF, SHF frequency bands, 300MHz~300GHz) circuits and perform one or more functions. Hotspots in the research field of microwave dielectric materials. Filters, duplexers, GPS antennas, chip capacitors, etc. made of microwave ceramic materials have the advantages of small size, light weight, good temperature stability, and low price. They are key components for the miniaturization and integration of modern communication equipment . [0003] Components made of microwave ceramics, such as cylindrical and coaxial dielect...
