Description
Technical field
The utility model 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.
Utility model content
The technical problem to be solved by the present invention is in view of the drawbacks of the prior art, provide a kind of waterproof performance survey
Trial assembly is set.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of waterproof performance test device is constructed,
The pressure change that mobile phone is judged using monocrystalline silicon pressure transmitter replaces direct immersion liquid using the leakproofness of test product.
In waterproof performance test device described in the utility model, the waterproof performance test device includes the waterproof
Performance testing device includes bottom plate, the third cylinder on bottom plate and third cylinder drawer appliance connected horizontally, on drawer appliance
It holds the fixation bracket of setting, fix the monocrystalline silicon pressure transmitter and vacuum generator on bracket.
In waterproof performance test device described in the utility model, the drawer appliance include drawer panel and have type
The lower jig of chamber；The upper jig with type chamber is equipped with above the lower jig, the upper jig is in fixed internal stent；On described
Jig and lower jig form seal cavity；The drawer appliance is connected by sliding rail with bottom plate.
In waterproof performance test device described in the utility model, the other side is additionally provided with air exhaust head and on the bottom plate
Two cylinders, 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 described in the utility model, the monocrystalline silicon pressure transmitter is examined equipped with pressure
Survey module.
In waterproof performance test device described in the utility model, the fixed pedestal upper end is additionally provided with the first cylinder,
First cylinder is connected with upper jig.
The waterproof performance test device for implementing the utility model, has the advantages that the monocrystalline in the utility model
The small air pressure change of Silicon pressure transmitter micrometer, the pressure detecting module detect total atmospheric pressure value.The effect of the vacuum
It is to generate vacuum, the compatible positive/negative-pressure two ways measurement of this device.The waterproof performance test device is using test product
Leakproofness replaces direct immersion liquid, the testing efficiency not only improved, and can avoid the waste of sampling with full inspection, dispatches from the factory
Product quality is more guaranteed.
