AI Technical Summary

Technical Problem

Existing cleaning methods for quartz pendulums can damage them, and the cleaning effect cannot meet the requirements for production and use. Furthermore, they cannot guarantee the adhesion and conductivity of the film layer, thus affecting the performance of the quartz flexural accelerometer.

Method used

A combination of etching followed by foaming, ultrasonic cleaning, hot water cleaning, multiple deionized water cleaning, slow drying, and two aging treatments is employed to ensure the surface cleanliness of the quartz pendulum and the adhesion of the film layer, while reducing internal stress.

Benefits of technology

This improved the quality stability and film adhesion of the quartz pendulum, reduced production costs, and ensured the measurement and control accuracy and pass rate of the quartz flexible accelerometer.

Abstract

The application relates to the quartz pendulum plate processing field, and aims to solve the problem that the existing quartz pendulum plate cleaning method cannot guarantee the quality stability of the quartz pendulum plate and proposes a processing method for improving the reliability of the quartz pendulum plate, which comprises the following steps: firstly, carrying out glue removal treatment on the etched quartz pendulum plate; secondly, heating an ultrasonic cleaning agent tank and a hot water tank; firstly, placing the quartz pendulum plate into the ultrasonic cleaning agent tank to carry out ultrasonic cleaning, then placing the quartz pendulum plate into the hot water tank to carry out cleaning, and then sequentially placing the quartz pendulum plate into multiple deionized water tanks to carry out cleaning; thirdly, placing the cleaned quartz pendulum plate into a slow-drawing baking equipment to carry out drying treatment; fourthly, placing the dried quartz pendulum plate into a vacuum drying box to carry out first aging treatment; fifthly, placing the quartz pendulum plate after the first aging treatment into a vacuum evaporation machine to carry out vacuum evaporation treatment; and sixthly, placing the quartz pendulum plate into the vacuum drying box again to carry out second aging treatment, so that the cleaning of the quartz pendulum plate is completed.
