Problems solved by technology
However, with this detection method, when the airtightness of the smart watch to be detected is not good, only the overall air leakage can be determined, and the specific air leakage position on the smart watch to be detected cannot be further determined, and the detection accuracy is relatively low. Low

The invention relates to the technical field of intelligent product air tightness detection, and discloses an air tightness testing device and method. The air tightness testing device comprises a rack, a bearing jig, a sealing part and a detection assembly, the bearing jig comprises a base and a cover body which are oppositely arranged, at least one of the base and the cover body is slidably arranged on the rack, the cover body can cover the base, a containing cavity is formed between the base and the cover body, a to-be-tested workpiece is borne in the containing cavity, the to-be-tested workpiece is provided with a plurality of to-be-tested holes, the cover body is provided with a plurality of mounting holes which are opposite to the to-be-tested holes one by one, the cover body is also provided with an air vent communicated with the containing cavity, the air vent is used for introducing gas, a sealing part is arranged in each mounting hole in a sliding manner, and the sealing part can seal the corresponding to-be-tested hole; and the detection assembly is used for collecting leaked gas in the containing cavity. The air tightness testing device can judge the specific position of air leakage on the workpiece to be tested, and the detection result is accurate.
Description
technical field [0001] The invention relates to the technical field of air tightness detection of smart products, in particular to an air tightness test device and a test method. Background technique [0002] The function of a smart watch is similar to a personal digital assistant. In addition to indicating the time, it should also have one or more functions such as reminder, navigation, calibration, monitoring and interaction. With the continuous development of science and technology, smart watches The field of application is also expanding. [0003] Before the smart watch leaves the factory, it is usually necessary to test the airtightness of the smart watch. The existing test method is usually to place the smart watch to be tested in the corresponding accommodation space, then inject gas into the accommodation space, and A test instrument is used to collect whether the gas leaked from the accommodating space is within a preset range. However, with this detection method,...
