Description
Technical field
The utility model is related to a kind of quartz-crystal resonator sealing performance leakage detection apparatus.
Background technology
In press seal, resonator inside requires to vacuumize and be filled with nitrogen quartz-crystal resonator, to ensure quartz wafer
Be not corroded and can normal starting of oscillation, quartz-crystal resonator completes press seal, after soldering and sealing, needing to Quartz crystal resonant
The sealing performance of device is detected, quartz-crystal resonator encapsulation after whether gas leakage, be crystal product reliability important indicator
One of.Traditional quartz-crystal resonator detection method is liquid pressing detection method, and the detection method of this method is：By quartz-crystal
Body resonator, which is immersed in alcohol, to be placed into vacuum pressed tank, and compressed air is then added into vacuum pressed tank, makes vacuum pressed
Pressure in tank is maintained at 4.5kg, and the time is 30 minutes, then takes out quartz-crystal resonator, to it into line frequency, electrically etc.
Parameter detecting, if quartz-crystal resonator sealing performance is not up to standard, during the test, alcohol will pass through quartz-crystal resonator
On leak source enter the inside of quartz-crystal resonator, lead to that quartz-crystal resonator frequency, electrically etc. parameters change,
Operating personnel can judge whether the sealing performance of quartz-crystal resonator is up to standard according to the result of electrical testing.This detection skill
Art needs to clean pressure vessel before testing, clamping locking, and operating process is cumbersome, detection sensitivity and detection efficiency
It is relatively low, it is mismatched, and due to the raising of container inner pressure with production production capacity, having certain probability leads to quartz-crystal in container
Body resonator distorted appearance causes to scrap, so need that existing detection method is further improved with equipment,
A kind of high detection sensitivity, detection efficiency height, quartz-crystal resonator sealing performance leakage detection apparatus easy to operation is developed just to show
It obtains necessary.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of detection sensitivity
High, detection efficiency height, quartz-crystal resonator sealing performance leakage detection apparatus easy to operation.
Technical solution is used by the utility model：The utility model includes vacuum tank and negative-pressure vacuum generator, institute
It states negative-pressure vacuum generator and is arranged on the vacuum tank side and passes through connecting tube and be connected with the vacuum tank, the negative pressure is true
Empty generator can vacuumize the vacuum tank, and the side of the vacuum tank is additionally provided with control device, the control device
Including the time relay and vacuum pressure display, the time relay is electrically connected with the negative-pressure vacuum generator, described
Vacuum pressure display is connected with the vacuum tank.
It being further described as to said program, the top of the vacuum tank is additionally provided with openable and closable cover,
The cover can be fixed by clamping spanner and the vacuum tank.
It is further described as to said program, the vacuum tank tank interior is additionally provided with liner, and the liner can
To hold quartz-crystal resonator to be tested and test solution.
It is further described as to said program, the quartz-crystal resonator sealing performance leakage detection apparatus further includes bottom
Seat, the vacuum tank, the negative-pressure vacuum generator and the control device are fixedly connected by stent with the pedestal.
The beneficial effects of the utility model are：The utility model can be more accurately to stone than traditional compression testing device
The leakproofness of English crystal resonator is detected, during applied voltage test, due to inside quartz-crystal resonator also for vacuum state simultaneously
And by certain air pressure level, even if test liquid is also difficult to be filled in the case that product to be tested has leak source under pressurised conditions
Into quartz-crystal resonator inside, it is thus possible to which there is a situation where leakproofness fails to judge, test leakage, product hermeticity can cannot get phase
The guarantee answered, but when using negative-pressure vacuum test device, the pressure in vacuum tank gradually reduces, and will not treat test product
Appearance has an impact, and effectively reduces product and unnecessary scrap is generated due to test, it can be seen that, the utility model tool
Standby easy to operation, detection sensitivity higher, effectively inhibits the characteristics of scrappage at detection efficiency higher.
