Embodiment Construction

[0062] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0063] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0064] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention provides an airtightness test device and method. The device comprises an air pressure test assembly, an upper die and a lower die which is arranged opposite to the upper die. The airtightness test device provided by the invention can carry out positive and negative air pressure airtightness tests, and realize the visualization of test results. The upper die and the lower die are aligned in real time, so that high test accuracy and relatively high data repeatability and relevance are achieved. A sealing assembly is in contact with a component to be tested, so that damage to the appearance of the component to be tested is reduced. The sealing assembly can be disassembled and replaced rapidly, so that the test efficiency of the test device is improved. A multi-power sealing structure is used for sealing step by step, so that stress on the component to be tested is reduced, and the process problem in the component to be tested can be debugged and analyzed. A pre-pressing function is realized, so that the stability of airtightness data can be improved effectively.

Description

technical field [0001] The invention belongs to the field of air tightness testing, and more specifically relates to an air tightness testing device. Background technique [0002] At present, electronic products have higher requirements on the airtightness of products. Good airtightness can make electronic products have better waterproof and dustproof performance. Therefore, the airtightness test of the electronic product, that is, the airtightness test of the components of the electronic product (which may specifically refer to the casing of the electronic product), seems quite necessary. [0003] However, the airtightness test of the electronic product is easy to cause damage to the components of the electronic product to be tested, and the test efficiency is low, so it is difficult to test the airtightness of the electronic product components in batches. Contents of the invention [0004] The object of the present invention is to provide an airtightness testing device...
