Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a frequency modulation machine, in particular to a crystal oscillator automatic frequency modulation machine. Background technique [0002] Crystal oscillator is the abbreviation of quartz crystal oscillator. Crystal oscillator is a resonant device made by using the piezoelectric effect of quartz crystal (silicon dioxide). The production process of the crystal oscillator is to cut a thin slice (referred to as a wafer, which can be square, rectangular or circular, etc.) from a quartz crystal at a certain azimuth angle, and coat its two corresponding surfaces with a silver layer as an electrode. Solder a lead wire on each electrode and connect it to the pin, then perform frequency modulation and packaging, and add an IC to form a crystal element of the oscillation circuit inside the package to make a crystal oscillator. The crystal oscillator package generally uses a metal shell, ...

AI Technical Summary

Problems solved by technology

The problems of this processing method are: 1. Manual grinding of crystal oscillators has high requirements for workers’ operations, and repeated grinding and measurement lead to large errors in the frequency of crystal oscillators; 2. High requirements for the number of workers are not conducive to production. Maintenance of the workshop environment, dust and other pollutants in the air can easily lead to product quality defects; 3. Manual processing has low work efficiency and high production costs
