Description

Technical Field

[0002] A quartz crystal resonator is an electronic component that uses the piezoelectric effect of a quartz crystal to generate a high-precision oscillation frequency. It is a passive component. During the production process, the quartz crystal resonator needs to be tested for airtightness to prevent short circuits or open circuits when used in subsequent circuits. An airtightness detection device is required for testing.

[0003] When the existing device is testing, in order to ensure that the terminal socket on the resonator can be aligned with the terminal post used for testing, a limit groove needs to be set. Although the limit groove can ensure the alignment of the terminal socket and the terminal post, it cannot adapt to resonators of different models and has low practicality. The sealing structure between the test box and the cover plate of the existing device is single, and the risk of air leakage during testing is high, which will directly affect the detection accuracy when leakage occurs.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a resonator airtightness detection device and a detection method thereof are provided, in order to achieve a more practical purpose. Summary of the invention

The test should ensure that the four resonators (5) are located between the clamping blocks (302) and that the resonators (5) are located at the initial center position of the clamping blocks (302); 03. Control the eight second electric cylinders (301) to extend so that the clamping block (302) contacts the resonator (5); 04. Control the four first electric cylinders (202) to retract, and the four first electric cylinders (202) drive the cover plate (101) to move downward. At this time, the resonator (5) is aligned with the terminal post (601) under the movement of the limit block (403). After the cover plate (101) is completely closed, the terminal post (601) contacts the terminal seat on the resonator (5); 05. Start the air supply pump box of the peripheral device to supply air to the four detection areas. At this time, observe the value on the pressure gauge (7) and the value on the resonator (5) detector.
