Quantitative dispensing device for LED display module processing

Abstract

The invention relates to the technical field of dispensing equipment, in particular to a quantitative dispensing device for LED display module processing, which comprises a workbench, supporting columns are symmetrically and fixedly connected to the upper surface of the workbench, a horizontal plate is fixedly connected to the upper surfaces of the supporting columns, and a supporting plate is fixedly connected to one side, away from the supporting columns, of the horizontal plate. The upper surface of the supporting plate is fixedly connected with a servo motor, one side of the servo motor is rotationally connected with a driving rotating shaft, the driving rotating shaft is sleeved with a protective sleeve, and the outer surface of the driving rotating shaft is fixedly connected with an extrusion protruding block on the front side of the protective sleeve. The induced draft fan generates wind power, blowing force towards the outer side is generated in the air outlet pipe located below the protection box, air flow on the surface of a product is accelerated, air accelerates cleaning of particles on the surface of the product and fixing of glue liquid, the waiting time is shortened, and therefore the cleaning effect can be achieved; and the effects of accelerating the fixation of the glue solution and reducing the waiting time can be achieved.

Description

technical field [0001] The invention relates to the technical field of dispensing equipment, in particular to a quantitative dispensing device for LED display module processing. Background technique [0002] The LED module is composed of light-emitting diode quadrilateral modules integrated with multiple rows and columns. The LED module is a widely used product in LED products. It is mainly used to display the night effect of advertising fonts and logos. It uses text or logos as the medium. Installation On the top of the building or on the wall, it can not only show the daytime effect of the logo, but also use LED as a light source; [0003] In the few existing dispensing control methods, people have tried to use various means to accurately point out the volume of the set viscous fluid, but the existing dispensing equipment cannot achieve the effect of quantitative dispensing, and often occurs The situation of overflowing glue leads to too much glue on the LED module board,...

Problems solved by technology

[0006] By shielding the dispensing tube with the shielding covers on both sides, the air is prevented from contacting the residual glue on the inner wall of the dispensing tube, so that the glue is fixed and blocked the outlet of the dispensing tube, and at the same time it helps to improve the quality of the glue and the efficiency of dispensing. Therefore, the effect of anti-blocking is achieved, and the problem that the existing residual glue will dry out in contact with the air and cause the blockage of the dispensing head; by making the piston at the lower end of the piston rod squeeze the glue inside the glue tube, the glue will flow from the point The inside of the hose drips onto the product, and the piston rod moves the same distance each time, that is, the dispensing amount is the same, so the same amount of dispensing at the extrusion can be achieved, and the effect of quantitative dispensing can be achieved, and the equipment can be improved. The effect of glue dispensing, through the induced fan to generate wind, the inside of the air outlet pipe located under the protective box generates a blowing force to the outside, accelerating the air flow on the surface of the product, and the air accelerates the cleaning of particles on the surface of the product and the fixation of the glue. It helps to reduce the waiting time, so it can not only achieve the effect of cleaning, but also achieve the effect of accelerating glue fixation and reducing waiting time
