Quartz crystal frequency fine tuning system and device

Abstract

The invention provides a quartz crystal frequency fine tuning system and device, and the system comprises a pedestal, a rotary hinge seat, a lifting rod, a sliding seat, a fixed frame, a fixed plate, a conduction support, a connection socket, a connection seat, a lifting mechanism, and an angle adjustment mechanism. The height of the fixing plate is adjusted through the lifting mechanism, the inclination angle of the fixing plate is adjusted through the angle adjusting mechanism, the quartz crystal can be conveniently adjusted and machined through etching equipment, the corresponding quartz crystal can be selected through the relay set in the machining process, the vibration frequency of the quartz crystal can be measured in real time, and adjustment of machining fine adjustment equipment is facilitated. Due to the selection function of the relay set, the quartz crystals on the whole fixing plate can be machined at a time each time, batch machining of the quartz crystals is achieved, the fixing plate is detachably installed on the fixing frame, electric connection is achieved through cooperation of the connecting socket and the connecting base, and the quartz crystals can be conveniently placed in the containing groove of the fixing plate.

Description

technical field [0001] The invention relates to the technical field of quartz crystal processing, in particular to a quartz crystal frequency fine-tuning system and device. Background technique [0002] Quartz crystal resonators have been widely used in military, communications, computers, household appliances and various industrial electronic equipment due to their excellent frequency stability, high Q value, high oscillation frequency and small size. The continuous development of the quartz crystal resonator has higher and higher requirements for the accuracy of the quartz crystal resonator. The precise adjustment of the frequency of the quartz crystal resonator is a hot issue in research and production at home and abroad. The quartz crystal is fine-tuned in the process, usually by laser etching, ion etching, magnetron sputtering, etc., which is to achieve thinning of the film by transferring energy to the surface film of the quartz crystal and peeling it off from the bott...

Problems solved by technology

[0003] Publication No. CN207351546U provides a quartz crystal frequency plate quality detection device, which is set on the upper fixed splint and the lower fixed splint by setting the detection port of the frequency pickup , and then place the quartz crystal on the upper and lower fixing splints for detection, so that the frequency pickup can detect the frequency of the quartz crystal, which is convenient for later fine-tuning. This is also the conventional setting of the current quartz crystal frequency fine-tuning system, which can only detect each time Fine-tune a piece of quartz crystal. After each adjustment, you must remove the adjusted quartz crystal and then install a new one. The size of the quartz crystal is small. This operation is very inefficient, and it is very difficult to place the quartz crystal. trouble
