Dispensing method for LED display screen and dispensing device for LED display screen

Abstract

The invention discloses a dispensing method for an LED display screen and a dispensing device for the LED display screen. The LED display screen comprises a circuit board and multiple LED lamps arranged on the circuit board. The dispensing method for the LED display screen includes the steps that the circuit board including the multiple LED lamps is arranged on a heating table of the dispensing device; the single-time glue spraying amount of a dispensing nozzle of the dispensing device is set according to the distance between the adjacent LED lamps; an adhesive in an adhesive cylinder of the dispensing device is heated to the target temperature, and the dispensing nozzle of the dispensing device is used for extruding out the adhesive so that the part between every two adjacent LED lamps can be filled with the adhesive; and the circuit board obtained after dispensing is baked so that the adhesive formed between the LED lamps in a filling manner can be formed. By means of the dispensingmethod for the LED display screen and the dispensing device for the LED display screen, the single-time glue spraying amount of the dispensing nozzle is set according to the distance between the adjacent LED lamps, the temperature of the adhesive is controlled to be the target temperature, the requirement for conducting dispensing between small-distance light sources can be met, the phenomenon ofglue pulling or glue hanging is avoided, and the performance of the LED display screen is improved.

Description

technical field [0001] The present application relates to the technical field of LED display screens, in particular to a dispensing method for LED display screens and dispensing equipment for LED display screens. Background technique [0002] The LED display is mainly to install a large number of LED lights on the circuit board, and then the circuit board drives the LED lights to emit light to realize the display. During the production process, after the LED lamp is installed on the circuit board, glue needs to be applied to the edge of the LED lamp to fix the LED lamp on the circuit board. In order to prevent the glue from directly pointing on the LED lamp and thus affecting the luminous effect of the LED lamp, the glue is usually dispensed between the LED lamps during the dispensing process, that is, the glue is placed between the LED lamps, and then the fluidity of the glue is used to flow To the edge of the LED light to achieve the fixation of the LED light and the circ...

Problems solved by technology

[0004] In view of the above defects or improvement needs of the prior art, this application provides a dispensing method for LED display screens and dispensing equipment for LED display screens, the purpose of which is to set dispensing nozzles according to the distance between adjacent LED lights The amount of glue sprayed at a time, and the temperature of the glue is controlled at the target temperature, which can meet the needs of dispensing glue between small-pitch light sources, avoid the occurrence of glue pulling or hanging glue, and improve the performance of the LED display; thus Solve the technical problem that in the process of LED dispensing, the dispensing needle is prone to pulling or hanging glue, resulting in uneven dispensing of LEDs, which will reduce the quality of LED products
