Abstract

The invention provides a device and method for detecting the airtightness of a special part of a product, and relates to the technical field of airtightness detection devices. The device comprises a sealing mechanism, a testing box for placing a detected product, and a press-fit positioning mechanism. The test box moves in the first direction, wherein the first direction is a direction from a place where the detected product is placed to a work position for detecting the airtightness of the detected product. When the testing box moves to the work position for detecting the airtightness of thedetected product, the sealing mechanism is located at the upper end of the testing box, and the press-fit positioning mechanism drives the sealing mechanism to move to get close to or leave from the testing box. The sealing mechanism makes contact with the testing box to form a detection cavity for detecting the airtightness of the product. The device and method solve a technical problem that theairtightness of the special position and contour of the product cannot be detected in the prior art.

Description

technical field [0001] The invention relates to the technical field of airtightness detection devices, in particular to an airtightness detection device and an airtightness detection method at a special position of a product. Background technique [0002] Due to the particularity of the profile of the product to be tested, it is impossible to test the waterproof and airtightness of the product by directly testing the sealing ring. In order to realize some special contours and points of the product, it is necessary to do a waterproof and tightness test, so this indirect test method was developed and designed to realize the leaking point of the product that cannot be sealed directly for the leak test. Make sure that the product is on the market, can realize normal life, and has a waterproof level for diving. [0003] The information disclosed in this Background section is only intended to enhance the understanding of the general background of the present invention, and should...
