Embodiment Construction
[0040] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, and the described specific embodiments are only used to explain the present invention, and are not intended to limit the specific embodiments of the present invention.
[0041] The invention discloses a leak detection device for electronic products, and the electronic products include waterproof watches, waterproof mobile phones, waterproof lenses and the like. see figure 1 as shown, figure 1 It is a schematic diagram of the principle of the detection device of the present invention. The detection device includes a quantitative cavity 100 and a test cavity 200. The quantitative cavity 100 is set as a reference quantitative cavity, that is, a certain amount of gas enters the quantitative cavity 100; The test cavity 200 is used to house the product to be tested. Both the quantitative chamber 100 and the testing chamber 200 are airtightly arr...

The invention discloses a sealing detecting device and method for an electric product. The sealing detecting device and method for the electric product comprises a quantitative cavity, a measuring cavity, a first pressure sensor and a second pressure sensor, wherein the quantitative cavity and the measuring cavity are arranged in an airtight mode and communicated through a separation body, an air inlet cavity pipe is arranged on the quantitative cavity, an air outlet cavity pipe is arranged on the measuring cavity, the first pressure sensor is communicated with the quantitative cavity, and the second pressure sensor is communicated with the measuring cavity. Since the pressure sensors are adopted to read the intensity of the pressure of the whole measuring process and the intensity changing relationship of the pressure intensity, the sealing detection device and method for the electric product can accurately judge whether the sealing is qualified, calculates the sealing size of the product to be detected and detects whether the volume of the product is normal.
Description
technical field [0001] The invention relates to the field of detection of electronic products, more specifically, to the field of detection of airtightness of products with internal void structures. Background technique [0002] With the development of electronic products such as waterproof watches, waterproof mobile phones, and waterproof lenses, the detection of the sealing performance (referred to as sealing, that is, leak-proof) of products with a closed volume has become more and more important. In order to ensure the quality of such electronic products, every All electronic products need to be tested for airtightness before leaving the factory. At present, the airtightness detection methods of electronic products mainly include the following types: [0003] (1) Differential pressure air detection method [0004] The differential pressure air detection method is to pressurize the electronic product to be tested and the standard product respectively, and use a pressure...
