LED outdoor screen double-groove glue layer quick smearing device

Abstract

The invention discloses an LED outdoor screen double-groove glue layer quick smearing device. The LED outdoor screen double-groove glue layer quick smearing device structurally comprises a glue smearing moving arm, a machine body, an action arm, four expansion force arms, an anti-skid head and a base, wherein the glue smearing moving arm is perpendicularly fixed to the top of the machine body; a rotating shaft in the middle of the machine body is consistent with the center of the action arm; the four expansion force arms are uniformly fixed around the action arm; the ends of the expansion force arms are tightly attached to the anti-skid head through bolts; the bottom of the machine body is welded and fixed to the base; and the glue smearing moving arm is fixed to the top of the action armand is in signal communication with the action arm through a wire. To sum up, after improvement, the glue smearing moving arm is used for mechanically and rapidly carrying out waterproof treatment onthe edge of an LED lamp board, and better stability and better port flushness are realized due to a double-groove mode while waterproof treatment.

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
