On-line detecting device for quartz crystal product

Abstract

The invention discloses an on-line detecting device for a quartz crystal product. The on-line detecting device for the quartz crystal product comprises a lower computer responsible for front end dataacquisition, an upper computer responsible for back end data processing, a power supply module for supplying power to the lower computer and a quartz crystal oscillator. The lower computer comprises an oscillation starting circuit, a detection circuit and a single chip microcomputer control circuit. An amplification circuit receives a resonance signal output by the quartz crystal oscillator, and after amplification, the amplification signal is output, a resonance resistance detection circuit receives a resonance signal output by the quartz crystal oscillator, a voltage signal of resonance resistance is output; and the lower computer comprises a level conversion circuit and a computer. When the quartz crystal oscillator does not vibrate and has no resonance signal output, a self-oscillation-starting circuit automatically excites and outputs the resonance signal. The on-line detecting device for the quartz crystal product realizes online frequency detection, resonance resistance measurement and data transmission, and realizes various management functions in the upper computer, so that production efficiency and the qualified rate of the manufactured products are improved.

Description

technical field [0001] The invention relates to the technical field of quartz crystal detection, in particular to an online detection device for quartz crystal products. Background technique [0002] Today, with increasing emphasis on efficiency, the efficiency of production has been paid more and more attention by various enterprises. Off-line sampling and testing are used in the existing quartz crystal production, with few samples and low efficiency. At the same time, the data storage and analysis of the original manual inspection are difficult, and the production cannot be tracked and improved in time, thus reducing the production efficiency and product qualification rate. For quartz crystals with high precision requirements, this detection method seriously restricts large-scale and standardized production. Contents of the invention [0003] The object of the present invention is to provide an online detection device for quartz crystal products, so as to effectively o...
