1. Field of the Invention
The invention relates to a waterproof testing system and a method thereof, and more particularly to a waterproof testing system and a method thereof which determine whether the waterproof function of a sample is well by adjusting gas pressure for the sample.
2. Description of Related Art
With currently available techniques, a conventional gas positive/negative pressure tester has to rely on human's visual observation to obtain the waterproof test data of a sample; whether the waterproof function of the sample is good or not is determined at human's discretion. In that case, the deviation results from human negligence affects the test data and may lead to a wrong judgment over the waterproof function of the sample. Besides, human inspection may cause human resource costs as well as testing time to increase and the efficiency of an overall testing process may also decrease.
The invention provides a waterproof testing system, including a sample, a gas tester, and a master device. The master device is connected to the gas tester to control the gas tester to adjust gas pressure for the sample and to control the gas tester to read an effect pressure value that is being affected on the sample. Then the master device determines whether the effect pressure value is equal to a goal pressure value. If the result is positive, then the gas tester is controlled to adjust the gas pressure for the sample to the goal pressure value to last for a first length of time. Then the gas tester reads the effect pressure value affected on the sample and the master device determines whether the effect pressure value still maintains within a first pressure range relative to the goal pressure value. If the result is positive, then the gas tester is controlled to stop adjusting the gas pressure for the sample and to read the effect pressure value affected on the sample. Then the master device determines whether the effect pressure value still maintains within a second pressure range relative to the goal pressure value. If the result is positive, then the master device continues to determine whether a time in which the effect pressure value maintains within the second pressure range relative to the goal pressure value has exceeded a second length of time. If the result is positive, then it is determined that the waterproof test is successful.
In one embodiment of the invention, the waterproof testing system further includes that when the master device controls the gas tester to adjust the gas pressure for the sample and determines that the effect pressure value has not been equal to the goal pressure value, then the master device continues to determine whether an operation of adjusting the gas pressure has exceeded a predetermined time limit. If the result is positive, then it is determined that the waterproof test fails.

The invention provides a waterproof testing method, using a gas tester to adjust gas pressure for a sample to test the waterproofing capability of the sample. The waterproof testing method includes controlling the gas tester to adjust the gas pressure for the sample and controlling the gas tester to synchronously read an effect pressure value being affected on the sample; determining whether the effect pressure value is equal to a goal pressure value; if the result is positive, then controlling the gas tester to adjust the gas pressure for the sample to the goal pressure value to last for a first length of time, then reading the effect pressure value affected on the sample; determining whether the effect pressure value still maintains within a first pressure range relative to the goal pressure value; if the result is positive, then controlling the gas tester to stop adjusting the gas pressure for the sample and reading the effect pressure value affected on the sample; the master device determining whether the effect pressure value maintains within a second pressure range relative to the goal pressure value; if the result is positive, then the master device continues to determine whether a time in which the effect pressure value maintains within the second pressure range relative to the goal pressure value has exceeded a second length of time; if the time has exceeded the second length of time, then it is determined that the waterproof test is successful.
Based on the above, the invention provides a waterproof testing system and a method thereof The master device uses the gas tester to adjust the gas pressure for the sample and obtains test data automatically for determining whether the waterproof test for the sample is successful. Human labor is no longer required for interpreting the test data for the waterproof capability of the sample, so a more objective and accurate judgment over the waterproof capability of the sample may be made. Also, human labor is no longer required for carrying out testing steps, so the overall waterproof testing process may run faster and more efficiently, thereby decreasing human resource costs to a large extent.
In order to make the aforementioned features and advantages of the invention more comprehensible, embodiments accompanying figures are described in detail below.
If the result in the step S215 is positive, then the test enters the pressure stabilizing stage of the waterproof testing method. The master device 110 controls the gas tester 120 to adjust the gas pressure for the sample 130 to the goal pressure value to last for a first length of time (step S230), wherein the first length of time may be further designed depending on the demand for the accuracy of the waterproof test. Thereafter, the gas tester 120 reads the effect pressure value affected on the sample 130 (step S235). Then, the master device 110 determines whether the effect pressure value still maintains within a first pressure range relative to the goal pressure value (step S240). In other words, the step S240 is to determine whether the effect pressure value affected on the sample 130 is within an acceptable deviation range at an upper and lower limit relative to the goal pressure value. The first pressure range may be further designed by users depending on the demand of the test. If the result in the step S240 is negative, then it is determined that the waterproof test fails (step S225).
If the result in the step S240 is positive, then the test enters the pressure holding stage of the waterproof testing method. The master device 110 controls the gas tester 120 to stop adjusting the gas pressure for the sample 130 (step S245). Also, the master device 110 controls the gas tester 120 to read the effect pressure value affected on the sample 130 (step S250). The master device 110 then determines whether the effect pressure value maintains within a second pressure range relative to the goal pressure value (step S255). Similarly, the step S255 is to determine whether the effect pressure value affected on the sample 130 is within the acceptable deviation range at the upper and lower limit relative to the goal pressure value. The second pressure range may also be further designed by the users depending on the demand of the test. If the result in the step S255 is negative, then it is determined that the waterproof test fails (step S225).
If the result in the step S255 is positive, then the master device 110 continues to determine whether a time in which the effect pressure value maintains within the second pressure range relative to the goal pressure value has exceeded a second length of time (step S260), wherein the second length of time may also be further designed depending on the demand for the accuracy of the waterproof test. If the result in the step S260 is negative, then the step S250 is resumed. The master device 110 continues to control the gas tester 120 to read the effect pressure value affected on the sample 130 to determine whether the effect pressure value maintains within the second pressure range relative to the goal pressure value. When the result in the step S260 is positive, it means that the effect pressure value is still able to maintain within the second pressure range after the second length of time, and then it is determined that the waterproof test is successful (step S265).
Base on the above, the invention provides a waterproof testing system and a method thereof. The master device uses the gas tester to adjust the gas pressure for the sample and to determine whether the waterproof test for the sample is successful through the pressure applying, stabilizing, and holding stages. The invention uses the master device to obtain the test data automatically. Human labor is not required for interpreting the test data for the waterproof capability of the sample. Therefore, the judgment over the waterproof capability of the sample may be more objective and accurate so that human errors may be avoided. Meanwhile, human labor is no longer required for carrying out testing steps, so the overall waterproof testing process may run faster and more efficiently, thereby decreasing human resource costs to a large extent.

It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the invention without departing from the scope or spirit of the invention. Therefore, the protecting range of the invention falls in the appended claims.
