Abstract

The invention discloses a quartz crystal resonator produced, researched and developed on the basis of novel devices. The quartz crystal resonator has a known structure, and is produced by three novel devices, namely, a spiral high-speed chamfering corrugated barrel, a three-dimensional glue dispenser and an automatic soldering and welding mold changing machine. Through the corrugated spiral barrel, a wafer is chamfered more uniformly; damage to the surface of the wafer is reduced; and the wafer has the characteristics of wide temperature and stable electric parameter. Through a three-dimensional glue dispensing process, the positions and sizes of the wafer and glue points are more uniform, stable and consistent during glue dispensing operation, and the falling resistance and impact resistance of the quartz crystal resonator are enhanced. Through a soldering and welding mold changing device, automatic operation of mold changing in a soldering and welding process is realized, and the accuracy and stability of the quartz crystal resonator are improved.

Description

technical field [0001] The invention relates to the field of quartz crystal production, in particular to a quartz crystal resonator produced and developed based on a new device. Background technique [0002] Quartz crystal resonator, also known as quartz crystal, commonly known as crystal oscillator, is a resonant element made of the piezoelectric effect of quartz crystal. It has highly stable physical and chemical properties, making it an important component for stabilizing and selecting frequencies. With the rapid increase in the application of intelligent terminal equipment, the requirements for quartz crystals are getting higher and higher; in the production of quartz crystal resonators, the uneven chamfering of the wafer is likely to cause damage to the surface of the wafer, and the dispensing position is inaccurate or uneven. Affect the drop and impact resistance of the quartz crystal resonator; sealing and welding will affect the sealing of the quartz crystal resonato...
