Abstract

The invention provides an LED module glue coating process and an LED module. The LED module glue coating process comprises the following steps: ion cleaning, glue spraying, vacuumizing, glue cleaning and baking. According to the LED module glue coating process, plasma equipment is firstly adopted to clean the LED module, so that the plasma covers the surface of the whole LED module to be coated with glue; secondly, glue is sprayed on the LED module subjected to plasma cleaning, so that LED lamp bases, bonding pads and the surface of a PCB of the LED module are covered with the glue; then the LED module subjected to glue spraying is subjected to vacuumizing treatment, so that the glue permeates into each part of the LED module; and then, the LED module subjected to vacuumizing treatment is cleaned so that glue on the lamp surface of the LED module can be removed, and finally, the LED module subjected to glue cleaning is baked so that curing of the glue on the LED module can be completed. The strength of the LED module coated with the glue can be improved, and the LED module is waterproof and moistureproof.

Description

technical field

[0001] The invention belongs to the technical field of LED display screens, and more specifically relates to a glue coating process for an LED module and an LED module. Background technique

[0002] In the prior art, outdoor LED display module products are packaged with silica gel, and the silica gel becomes black after curing. The operation method is: put the LED display module with the light-emitting surface facing up and place it in the tooling fixture, and then pour glue directly from the light-emitting surface, that is, Inject silica gel so that there is a layer of black potting glue on the surface of the LED display module. This glue is mainly to protect the LED lamp pins and pads from absorbing water, but this potting glue has poor adhesion and weak strength; water vapor can easily penetrate into the Inside, there is no moisture-proof ability, and it is easy to absorb moisture during use.
