Dispenser Ejection Dispensing Module

Abstract

The invention relates to an ejection type dispensing module of a glue dispenser, comprising a rubber outlet tube and a rubber extrusion sleeve slidingly sleeved outside the rubber outlet tube; when the rubber outlet tube moves toward the head of the rubber outlet tube relative Extrude the rubber tube radially to make the glue come out from the head; there are several piezoelectric shrapnels evenly arranged outside the head of the rubber outlet tube; The glue drop is ejected to its front; the ejection type dispensing module of the dispenser uses the high viscosity of the glue itself to decompose the dispensing process into extrusion and elastic, combining the advantages of the two methods to achieve faster , More stable and more accurate glue and viscose, to avoid glue dragging, drawing, etc., the pressure required for glue is small, and the viscose has wide applicability, which is conducive to dispensing operations for various parts with complex structures.

Description

technical field [0001] The invention relates to the field of dispensing machines, in particular to the ejection type dispensing module of the dispensing machine. Background technique [0002] The actuator of the dispensing machine is mainly responsible for dispensing operations, and the driving mechanism can help the actuator to achieve more accurate and high-quality dispensing, which of course also depends on a scientific and reasonable control system. [0003] The actuator is composed of two parts, the manipulator and the torso. The manipulator operates in a straight line during the operation. In order to cooperate with the operation of the manipulator, the so-called linear hydraulic cylinder, swing hydraulic cylinder, electro-hydraulic pulse motor, servo hydraulic motor, AC servo motor, DC servo motor and stepping motor are generally used as actuators. The torso of the dispenser is the main part of the dispenser, including the installation arm, power source, brackets fo...

AI Technical Summary

Problems solved by technology

[0004] The speed of the existing dispensing machine is relatively slow. The main reason is that each dispensing process requires multiple actions of the manipulator and the torso. The movement is complex and the total stroke is long. It is necessary to consider the problem of overcoming the inertial acceleration and deceleration of the manipulator and the torso, etc.;

[0005] Existing dispensing machines are difficult to choose for parts with narrow paths and deep positions, and the efficiency is low. Because the dispensing positions with narrow paths and deep positions need slender glue needles for dispensing, the required glue pressure The pressure is high, the reaction time is long, the glue output is difficult to control, and the life is short; and this kind of glue needle is not suitable for the position where the surface part needs a large amount of glue. It is necessary to replace the dispensing module or dispense glue on a different dispenser. Low, the dispensing effect is poor, most parts need to be dispensing at the same time, the scope of application is small

[0006] Existing glue dispensing machines are prone to unfavorable situations such as glue dragging and wire drawing, and the need for ultra-high-quality glue will undoubtedly increase production costs
