Problems solved by technology

However, it is sealed by an internal and external overlapping structure, which is prone to gaps and cannot prevent the leakage of water vapor, oily smoke, and dust
[0007] For the welding process, the contact positions of one or more parts to be sealed can be brought into close contact by welding, but the parts after welding are usually difficult to separate non-destructively, resulting in inconvenience, especially for electronic When the electrical box of the device is sealed by ultrasonic welding, it is easy to damage the electronic device

Abstract

A detachable sealing structure and a sealing method thereof, the method comprising the following steps: providing a first structure and a second structure detachably connected together; Foam: after the liquid foam is solidified, the first structure and the second structure are installed together, and the first structure and the second structure are sealed by the solidified foam. The solution of the invention can realize the sealing of complex structures, easily disassemble the sealing structure, and avoid damage to electronic devices during the sealing process.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a detachable sealing structure and a sealing method thereof. Background technique [0002] In the prior art, there are various sealing methods to meet the requirements of different processes and scenarios. For example, for a detachable sealing structure, solid foam, sealing ring / pad, and internal and external lap structures can be used to connect the parts to be sealed; for a non-removable sealing structure, fusion welding can be used to connect the parts to be sealed, which can specifically include ultrasonic welding. and hot melt process. [0003] Specifically, for solid foam, the solid foam can be cut according to the size of the sealing area and filled onto the contact surface of the parts to be sealed, so that the effect of sealing and anti-leakage can be achieved through the solid foam. However, it is difficult to achieve sealing of complex structures. [0004] For the s...
