A rapid application device for double groove adhesive layer of LED outdoor screen

Abstract

The invention discloses a double-groove adhesive layer rapid application device for an LED outdoor screen. The rotating shaft at the top and the middle of the body is consistent with the center of the action arm. There are four expansion arms and they are evenly fixed around the action arm. The end of the expansion arm is closely fitted with the anti-skid head through bolts, and the bottom of the body is welded to the base. , the glued boom is fixed on the top of the moving arm and the two communicate with each other through wires. In summary, after the improvement of the present invention, the glued boom is used to mechanize and quickly waterproof the edge of the LED light board. The way of groove is waterproof and more stable, and the interface is more flush.

Description

technical field [0001] The invention relates to an LED assembly device, in particular to a device for quickly applying double-groove adhesive layers on an LED outdoor screen. Background technique [0002] LED advertising is a form of new media advertising. Advertisement words or pictures made of light-emitting diodes can gradually form video playback with the iterative update of products. Most LEDs are installed by splicing multiple pieces, especially for some plug-ins. Displays on uncovered poles require special treatment: [0003] Since the display screen is composed of a dense array of LED light-emitting diodes, in order to make the black border of the display segment smaller, the edge interval needs to be controlled very small. In order to be waterproof, the edge of the display panel needs to be coated with glue. The high heat generation of the board is easy to cause it to fall off, but if it is painted inside, the thickness is difficult to control, resulting in too lar...

AI Technical Summary

Problems solved by technology

[0003] Since the display screen is composed of a dense array of LED light-emitting diodes, in order to make the black border of the display segment smaller, the edge interval needs to be controlled very small. In order to be waterproof, the edge of the display panel needs to be coated with glue. The high heat generation of the board is easy to cause it to fall off, but if it is painted inside, the thickness is difficult to control and the gap is too large to affect the display effect, and because the sealing strip is heated and contracted, it is very easy to get damp when the light board is turned off in the early morning
