Abstract
The invention provides a GPS (Global Position System) module watergithness testing device, comprising a compressed air source, a valve switch P1, a sealed room and a gas pressure meter which are connected in sequence. A pressure regulating valve is installed between the sealed room and the valve switch; a starting switch S1 is connected in parallel on the valve switch; the on-off of the starting switch S1 is controlled by the valve switch; one end of the starting switch is connected with a direct current power source and the other end is connected with a timer; and an indicator light LED1 (light-emitting-diode) is connected on the timer. The GPS module watertightness testing device solves the problems in the prior art that the product testing time is too long, products with unqualified watertightness are scrapped due to that water enters the insides of the products, and that the manufacturing cost is increased; the risk of scrapping of the products is reduced through a pressure test method; the product detecting time is shortened; the production efficiency is improved; and the quality of the products is strictly controlled through the tested parameters of a pressurization test.
Description
Technical field
The present invention relates to a kind of GPS module waterproof test device, belonged to product waterproof test technical field.
Background technology
Along with development of science and technology, people require increasingly high to the water resistance of various devices.Usually people need put into product in the dark water of 1M when the GPS module is carried out waterproof test, and in water, stop taking-up after 30 minutes, and the outside of product is dried, and open product, and whether inspection inside exists steam, and judges with this whether product is qualified.
Make when testing in this way, need 1.5 meters dark buckets, and the bottom want 1.1 meters dark; Need in water, stop the long period, consuming time longer when product detects, cause the serious waste in man-hour; And the underproof product of waterproof can increase manufacturing cost because inner inlet causes product rejection.
And this method of testing can only test product, and the performing leak test of parts in can not producing.
Summary of the invention
Technical matters to be solved by this invention provides a kind of GPS module waterproof test device, can reduce the risk of scrapping of product, shortens product detection time, enhances productivity, and has controlled the quality of product through the test parameter strictness of applied voltage test.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of GPS module waterproof test device is characterized in that: comprise the compressed air gas source, valve switch P1, seal cavity and the rain glass that connect successively.
Aforesaid GPS module waterproof test device is characterized in that: also comprise a pressure regulator valve, said pressure regulator valve is connected between said valve switch P1 and the seal cavity.
Aforesaid GPS module waterproof test device is characterized in that: also comprise successively the direct supply, switch S 1 and the timer that connect, said switch S 1 with by said pressure switch P1 control break-make.
Aforesaid GPS module waterproof test device is characterized in that: be connected with a pilot lamp LED1 on the said timer.
Beneficial effect of the present invention is following:
1, reduce the product rejection risk: can not exist because of product because of technological problems causes the risk of product rejection, reduced unnecessary cost waste.
2, enhance productivity: can produce in batches, originally the method for testing needs could detect 10 parts of products at most in about 35 minutes, and new method of testing only needs just can accomplish in about 40 seconds the detection of 1 part of product, improves the production efficiency of producing line effectively.
3, stable testing property is strong: the quality of product has been controlled in the test parameter strictness of applied voltage test.
Description of drawings
Fig. 1 is the structural representation of GPS module waterproof test device of the present invention.
Embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figure 1, a kind of GPS module waterproof test device comprises the compressed air gas source, valve switch P1, seal cavity and the rain glass that connect successively.
Between seal cavity and the valve switch pressure regulator valve is installed; Be parallel with a starting switch S1 on the valve switch, said starting switch S1 has valve switch control break-make, and an end connects direct supply; Other end connection timer is connected with pilot lamp LED1 on timer.
Because the flowability of water and air is mobile identical, promptly all-pervasive, so when opening replacement hydraulic pressure and come the water resistance of test products, have identical effect and effect with air pressure.
When utilizing this device to carry out GPS mould waterproofing tests, at first product to be detected is put into seal cavity, open valve switch, the air pressure in the seal cavity is risen gradually; Regulate the air pressure in the seal cavity through pressure regulator valve, when rain glass is shown as 0.020MPa, the valve-off switch; Closing Switch S1 lights pilot lamp LED1 simultaneously, after the time of timer settings arrives; Pilot lamp extinguishes, and observes the atmospheric pressure value on the rain glass simultaneously, when being greater than or equal to 0.018MPa as if the interior air pressure of seal cavity this moment; The water resistance of judging this product meets the requirements, if atmospheric pressure value during less than 0.018MPa, judges that the water resistance of this product is undesirable.
The anti-water coefficient of different product is also inequality, can satisfy different testing requirements through the timing time of regulating pressure regulator valve, setting timer.
Because this device utilizes air pressure to replace hydraulic pressure, thereby it can not only test product, can also test the parts in the associated production.
In sum, a kind of GPS module waterproof test device provided by the invention can reduce the risk of scrapping of product, shortens product detection time, enhances productivity, and has controlled the quality of product through the test parameter strictness of applied voltage test.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the instructions just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain by appending claims and equivalent circle thereof.
