Embodiment 1

[0040] This embodiment provides a method for testing the airtightness of a product, including:

[0041] To judge the overall yield rate of the tested product, specifically, randomly sample the tested product, the number of samples shall not be less than the preset number of yield test pieces, conduct an air tightness test on the sampled tested product, and count the tested products The yield rate of the product meeting the airtightness requirements. When the airtightness test is carried out on the sampled products to be tested, the airtightness test shall be carried out by means of a separate test. Optionally, the above-mentioned number of yield tests may be 10 or 15. The number of yield test pieces should not be too large, otherwise the test efficiency will be reduced; and if the number of yield test pieces is too small, the true yield of the tested product cannot be measured.

[0042] If it is determined that the yield rate of the tested product is greater than 70%, the fi...

Embodiment 2

[0050] This embodiment provides a method for testing the airtightness of a product, including:

[0051] Judge the overall yield of the tested product.

[0052]If it is determined that the yield rate of the tested product is greater than 70%, the first test mode is used to perform an airtightness test on the tested product. The first test mode is: placing a predetermined number of tested products in an airtight test device, and the airtight test device can perform an airtight test on several tested products at one time. The first test mode performs a test and only outputs one test result. When the airtightness of the tested product meets the preset airtightness requirements, the output test result is qualified; when any one or more tested products are When the airtightness does not meet the preset airtightness requirements, the output test result is unqualified.

[0053] If the yield rate of the tested product is less than or equal to 70%, each tested product is put into a si...

Embodiment 3

[0057] This embodiment provides an airtight test device, which can be used to implement the first test mode and the second test mode in the first and second embodiments. Such as figure 1 As shown, the airtightness test device includes a cavity 1, a predetermined number of product tooling 2 and an airtightness leak detector. The product tooling 2 is arranged in the cavity 1, and the product tooling 2 can be used to carry the tested product and / or the standard test piece. The airtightness of the standard test piece meets the preset airtightness requirements. When the standard test piece is placed in each product tooling 2 and the airtightness test is performed, the test result shows that the airtightness meets the requirements. The airtightness leak detector is used to test the airtightness of the tested product or standard test piece placed on the product tooling 2 .

[0058] When carrying out the airtightness test, when the product tooling 2 all carries the tested product, i...

Abstract

The invention discloses an airtightness testing method and device of a product. The testing method includes: a yield of tested products is determined; if the yield of the tested products is larger than 70%, airtightness testing is carried out on a predetermined number of tested products simultaneously by using a first testing mode; if the yield of the tested products is less than or equal to 70%,airtightness testing is carried out on one tested product and a predetermined number of standard test pieces simultaneously by using a second testing mode, wherein the airtightness performances of thestandard test pieces meet a preset airtightness requirement; each testing of the first testing mode and the second testing mode outputs one testing result, the testing result demonstrates the qualification information if the airtightness performances of the tested products meet the preset requirement, and otherwise, the testing result demonstrates non-qualification information; and testing is carried out by the first testing mode, if the testing result demonstrates non-qualification information, each tested product of the testing is tested again by using the second testing mode. Therefore, the e efficiency of the product airtightness testing is improved.

Description

technical field [0001] The invention relates to the technical field of product air tightness testing, and more particularly, to a product air tightness testing method and device. Background technique [0002] In recent years, the technology of electronic products has developed rapidly, and devices such as mobile phones and tablet computers have become indispensable items in people's daily life. With the application of consumer electronic products more and more widely, the requirements for its performance and reliability are gradually increasing. Water resistance and air tightness are important indicators of the reliability and life of electronic products. Good water resistance and air tightness can prevent electronic products from being damaged by foreign objects and liquids and ensure the reliability of use. [0003] At present, in the field of airtightness testing, the commonly used airtightness testing device can only test one product at a time. Although this method can...
