Rapid air tightness detection device for quartz crystal resonator

Abstract

The invention provides an air tightness rapid detection device for a quartz crystal resonator, and relates to the technical field of detection equipment, and the device comprises a main body, the top of the main body is provided with a sealing groove, the side surface of the top of the main body is provided with a cover plate through a hinge, and the top of the main body is provided with a plurality of inner grooves; arc-shaped open grooves are formed in the two sides of the inner groove, open grooves are formed in the side face of the inner groove, a push plate in the inner groove is arranged on the inner side of the cover plate, and an inner plate in the inner groove is connected with a connecting plate on the side face of the main body; and the bottom plate is mounted at the bottom of the main body. When the air tightness detection device is used, the air pressure in the inner groove is reduced, and the sealing plate drives the convex block at the outer end of the inner rod to move upwards under the action of the spring to contact with the warning lamp switch at the bottom of the side surface of the rotating plate, so that the warning lamp at the top of the bottom plate is turned on. An operator needs to observe the change of the pressure gauge to judge the air tightness of the quartz crystal resonator, and the observation is time-consuming and labor-consuming.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a fast air tightness detection device for a quartz crystal resonator. Background technique [0002] Quartz crystal resonator is an electronic component that uses the piezoelectric effect of quartz crystal to generate high-precision oscillation frequency. When it is used in the later circuit, it will cause short circuit or open circuit. [0003] However, when the existing air tightness detection device is in use, the quartz crystal resonator is tested by injecting air pressure, and the operator needs to observe the change of the pressure gauge to judge the air tightness of the quartz crystal resonator, and the pressure gauge has a small number , It is time-consuming and laborious to observe, and when the air-tightness detection device is in use, the quartz crystal resonator needs to be clamped and fixed, and the clamping tool needs to be opened again when it is taken ...
