Abstract

The invention belongs to the technical field of air tightness detection, and discloses an air tightness detection device which is used for detecting the air tightness of a sheet covering the inner side of an orifice of a first through hole of a panel and comprises a carrier, a covering part and an air tightness detector. The carrier bears the panel, the covering part is arranged above the carrier and can ascend and descend, the covering part is provided with a first groove, a second groove is concavely formed in the covering part and/or a third groove is concavely formed in the carrier, and when the covering part abuts against the carrier, part of the covering part abuts against the panel, so that a first cavity is formed between the first groove and the panel, and the second groove and/or the third groove form a chamber of the second cavity; orifices at two ends of the first through hole are respectively communicated with the first cavity and the second cavity, the carrier or the covering part is provided with an inflation port communicated with one of the first cavity and the second cavity, and the air tightness detector detects the air pressure of the other one of the first cavity and the second cavity, so that the air tightness of the sheet is detected.

Description

technical field [0001] The invention relates to the technical field of air tightness detection, in particular to an air tightness detection device. Background technique [0002] The panel of the screen of an electronic product is usually provided with a handset hole, and the inside of the hole of the handset hole of the panel is covered with a mesh sheet. Before together, it is necessary to test the airtightness of the sheet covering the inner side of the hole of the earpiece hole on the panel of the electronic product to prevent water, air or dust from entering the electronic product during use, but currently there is no There is no instrument specially used for air tightness testing on panels of electronic product screens. [0003] Therefore, the above-mentioned problems need to be solved urgently. Contents of the invention [0004] The purpose of the present invention is to provide an airtightness detection device to detect the airtightness of the sheet covered inside...
