Embodiment 1

[0040] combine figure 1 with figure 2 As shown, a LED display module lamp seam glue filling process in this embodiment includes the following steps:

[0041] Step S10, the LED display module 10 to be glued is turned upside down on the adhesive film 20, and the adhesive film 20 is pasted on the turned-down LED display module 10 to be glued. face.

[0042] Specifically, prepare an adhesive film 20 with a certain viscosity and can be removed later and the LED display module 10 to be glued, spread the adhesive film 20 flat, and then place the LED display module 10 to be glued face down On the flat adhesive film 20, the adhesive film 20 is pasted on the lamp surface of the LED display module 10 to be glued upside down, and the stickiness of the adhesive film 20 can be used directly, or Auxiliary other means such as heat pressing. As an optimization, after the LED display module 10 to be glued is buckled upside down on the adhesive film 20 , the distance between each side of th...

Embodiment 2

[0057] The difference between this embodiment and the first embodiment is that the adhesive film in this embodiment is a hot-melt adhesive film, which is pasted on the lamp surface of the LED display module to be glued by hot pressing.

[0058] In step S10 of the first embodiment, the lamp surface of the LED display module to be glued is turned upside down on the adhesive film, and the adhesive film is pasted on the lamp surface of the LED display module to be glued. Such as image 3 with Figure 4 As shown, in this embodiment include:

[0059] Step S11, spread a silicone mold or release film 100 on the platform of the heat press machine.

[0060] Concretely, lay a piece of silicone mold or release film 100 on the hot press platform of the hot press. on the platform.

[0061] Step S12 , spreading a piece of hot melt adhesive film 20 on the silicone mold or release film 100 .

[0062] Specifically, a piece of hot-melt adhesive film 20 is spread flat on the silicone mold or...

Embodiment 3

[0071] The difference between this embodiment and embodiment one is that the composition of the sol tank is different, such as Figure 5 As shown, the LED display module lamp seam glue filling process in this embodiment includes the following steps:

[0072] Step S100 , turning the LED display module lamp to be glued face down on the adhesive film, and attaching the adhesive film to the lamp surface of the LED display module to be glued upside down.

[0073] Step S200, opening a through hole on the adhesive film.

[0074] Step S300, buckle the LED display module to be glued with the adhesive film upside down, with the adhesive film facing downwards, into a glue potting jig, and the glued upside down LED display module to be filled with the adhesive film The outer sides of the glued LED display module and the inner sides of the glue potting jig form a glue-holding groove.

[0075] Specifically, prepare a glue filling jig, put the LED display module to be glued with the glued ...

Abstract

The invention discloses an LED display module lamp seam glue pouring process, and belongs to the technical field of LED display screens. The glue pouring process comprises the steps that the lamp faceof the LED display module to be subjected to glue pouring is downwards buckled on a glue film in an inverted mode, and the glue film is attached to the lamp face of the LED display module to be subjected to glue pouring in an inverted mode; a through hole is formed in the adhesive film; fences are adhered to the four sides of the adhesive film, and the fences are folded to enable the fences, theinverted LED display module to be filled with the adhesive and the adhesive film to form an adhesive containing groove; glue is injected into the glue containing groove; connecting an air pipe into the through hole and vacuumizing until glue filling is completed to form a semi-finished product of the LED display module filled with glue; and the LED display module semi-finished product filled withthe glue is stood until the LED display module semi-finished product is cured. According to the whole process, only existing simple equipment needs to be adopted, the fluidity of glue in the lamp seams is good, meanwhile, the LED display module finished product with the lamp seams filled with the glue and thicker and more uniform glue filling thickness can be obtained with lower cost and higher efficiency, and the front face of the LED display module has the anti-collision, damp-proof and waterproof capacity.

Description

technical field [0001] The invention relates to the technical field of LED display screens, more specifically, it relates to a glue filling process for lamp seams of LED display modules. Background technique [0002] At present, due to packaging factors, the LED lamp beads in the LED display module are easy to enter moisture and cause short-circuit dead lights. In order to solve this problem, it is generally necessary to inject glue into the light gap of the LED display module through a glue filling method or process. As the dot pitch of the lamp beads in the LED display module becomes smaller and smaller, the width of the lamp seam between the lamp beads becomes smaller and smaller. In the existing glue filling method or glue filling process, the glue in the lamp seam The fluidity in the lamp is poor. On the one hand, the efficiency of glue filling is low. On the other hand, the glue filled in the lamp slit is less, and it is difficult to achieve a good protective effect o...
