Waterproof encapsulation structure and its integrated molding process

Abstract

A waterproof packaging structure includes a transparent cover, a grid and a T-shaped sealing rubber ring. The grid includes a middle dividing unit and a peripheral stepped supporting surface; a rectangular T-shaped sealing rubber is set at the sealing groove of the grid. ring; a transparent cover is placed on the T-shaped sealing rubber ring, and the special-shaped sealing glue is directly injected into the gap between the T-shaped sealing rubber ring and the end face of the transparent cover. The present invention aims at the technical problem of how to waterproof and seal LED lighting lamps in deep water and high pressure environments. It adopts sealant injection molding integrated molding technology to seal the transparent cover sheet and the grid used to separate the LED light-emitting chips under vacuum conditions. At the same time, it adopts The T-shaped sealing rubber ring and the injection-molded special-shaped sealing rubber allow the gap between the two parts to form an integrated sealing system. This structure completely solves the problem of water seepage gaps that still exist in other sealing methods, and the sealing effect is good. High-level sealing can still be maintained under deep water and high pressure environments.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of packaging of highly waterproof and anti-penetration LED lighting lamps, in particular to the processing technology of the packaging shell and packaging structure of LED lighting lamps that need to resist external high pressure, waterproof and anti-penetration in a high-pressure environment. [0003] 【Background technique】 [0004] The packaging system of the present invention is mainly aimed at highly waterproofing the LED lamps for lighting, not only can ensure the internal sealing performance under normal temperature and pressure, but also can be applied to deep water and high water pressure environments. [0005] In the prior art, most of the housings of LED lighting lamps are installed and fastened by screws, and one of the waterproof methods used is to use cold gel to seal the entire PCB board and the part of the circuit board, which is a partial sealing method; the other is It is to add a se...

AI Technical Summary

Problems solved by technology

[0006] However, this level of sealing is not suitable for sealing, waterproofing and anti-penetration in deep water and high pressure environment, because in high water pressure environment, it is simple to open a waterproof groove on the contact surface and set a waterproof rubber ring in the waterproof groove The structure is unable to resist strong external pressure

Failure in deep water, high pressure and high pressure environment, passive water seepage occurs, resulting in seal failure
