Description
Technical field
The present invention relates to a kind of test devices, more specifically to a kind of waterproof performance test device.
Background technique
With the development of the society, people are also more and more extensive to electronic product use in daily life and work.And it is electric
Sub- product, which has a problem in that, to get wet, so as the electronic products such as mobile phone, wrist-watch need to consider waterproof performance.It is currently
The sampling of the electronic products such as mobile phone is directly put into water or other liquid, certain depth and time are placed.It not only imitates in this way
Rate is low, and the product for impregnating liquid cannot be sold, so cannot 100% full inspection.
Monocrystalline silicon pressure transmitter is the piezoresistive effect using monocrystalline silicon, and when pressure changes, monocrystalline silicon generation is answered
Become, makes directly to be diffused in strain resistor above and generate and obtained accordingly with by the proportional variation of measuring pressure, then by bridge circuit
Voltage output signal.It may determine that the variation of pressure according to the voltage signal of output, so that the leakproofness for obtaining mobile phone is come
Judge whether it meets water-proof function.
Summary of the invention
The technical problem to be solved in the present invention is that in view of the drawbacks of the prior art, providing a kind of waterproof performance test dress
It sets.
The technical solution adopted by the present invention to solve the technical problems is: constructing a kind of waterproof performance test device, utilizes
Monocrystalline silicon pressure transmitter judges the pressure change of mobile phone, replaces direct immersion liquid using the leakproofness of test product.
In waterproof performance test device of the present invention, the waterproof performance test device includes the waterproof performance
Test device includes that bottom plate, the third cylinder on bottom plate and third cylinder drawer appliance connected horizontally, drawer appliance upper end are set
Monocrystalline silicon pressure transmitter and vacuum generator on the fixation bracket set, fixed bracket.
In waterproof performance test device of the present invention, the drawer appliance includes drawer panel and with type chamber
Lower jig；The upper jig with type chamber is equipped with above the lower jig, the upper bracket is in fixed internal stent；The upper jig
Seal cavity is formed with lower jig；The drawer appliance is connected by sliding rail with bottom plate.
In waterproof performance test device of the present invention, the other side is additionally provided with air exhaust head and the second gas on the bottom plate
Cylinder, second cylinder are located at air exhaust head upper end, the interface docking that the air exhaust head and seal cavity are reserved.
In waterproof performance test device of the present invention, the monocrystalline silicon pressure transmitter is equipped with pressure detecting mould
Block.
In waterproof performance test device of the present invention, the fixed pedestal upper end is additionally provided with the first cylinder, described
First cylinder is connected with upper jig.
Implement waterproof performance test device of the invention, has the advantages that the monocrystalline Silicon pressure in the present invention becomes
The air pressure change for sending device micrometer small, the pressure detecting module detect total atmospheric pressure value.
The effect of the vacuum is to generate vacuum, the compatible positive/negative-pressure two ways measurement of this device.The waterproofness
Energy test device uses the leakproofness of test product instead of direct immersion liquid, the testing efficiency not only improved, and can be complete
Inspection, avoids the waste of sampling, and factory product quality is more guaranteed.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:
