Embodiment Construction

[0043] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the application more thorough and comprehensive.

[0044] In the manufacturing process of display devices (such as smart phones, smart watches, tablet computers, TVs, etc.), an airtightness test is required after the screen is dispensed onto the casing, and products that fail the airtightness test will be regarded as unqualified. Good product. For this reason, it is necessary to remove the screen of the defective product from the housing and re-dispense the glue, and then perform the air ...

Abstract

The invention relates to an airtight maintenance method and a maintenance device. The airtight maintenance method is used for achieving airtight maintenance between a screen and a shell in a sample to be detected and comprises the steps of providing a jig with an air hole, placing the sample to be detected on the jig, enabling a cavity to be formed among the jig, the shell and the screen, and enabling the air hole to be communicated with the cavity; inflating the cavity from the air hole; marking the position of a gas discharge leakage port between the screen and the shell; exhausting air in the cavity from the air hole; and arranging a filling glue at the marked position, and blocking the leakage opening by the filling glue under the action that the air hole exhausts air from the cavity. According to the method, the leakage opening can be repaired without dismounting the screen so that the sample damage caused by dismounting can be prevented.

Description

technical field [0001] The present application relates to the field of airtight detection, in particular to an airtight inspection method and an inspection device. Background technique [0002] In the manufacturing process of display devices (such as smart phones, smart watches, tablet computers, TVs, etc.), an airtightness test is required after the screen is dispensed onto the casing, and products that fail the airtightness test will be regarded as unqualified. Good product. For this reason, it is necessary to remove the screen of the defective product from the housing and re-dispense the glue, and then perform the air tightness test again. However, during the disassembly process of the screen, it is particularly easy to cause damage to the screen (especially the flexible screen) and scratches on the casing. Contents of the invention [0003] Embodiments of the present application provide an airtight inspection method and inspection device that can effectively reduce p...
