Problems solved by technology

[0004] During the research and practice of the prior art, the inventors of the present invention have found that when the traditional glue dispenser is pressing the glue, the pressure of the glue is controlled by the air pressure. Because the air pressure is unstable, it is difficult to control accurately, and the viscosity of the colloid Uncertainty and other factors, each dispensing requires repeated debugging, it is difficult to accurately control the glue flow

Abstract

The invention discloses a glue dispensing control method, a glue dispenser and a related device. In the embodiment of the invention, the glue pressing rate of a glue pressing plug is calculated through obtaining the glue extruding rate information of a glue dispensing head, and a driving motor is controlled to drive the glue pressing plug to extrude glue through the glue dispensing head accordingto the calculated glue pressing rate. Compared with the prior art in which an air pressure glue pressing mode is adopted, the invention adopts the motor to drive the glue pressing, the glue extrudingrate is not influenced by the viscosity of glue, and the glue pressing rate and the glue extruding rate are in an accurate linear relation, therefore, accurate glue dispensing control is realized, and the glue dispensing is more uniform. In addition, when an operator performs glue dispersing each time, complex debugging is not needed so that the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a dispensing control method, a dispensing machine and related devices. Background technique [0002] Dispensing machine is a common equipment for industrial control of dispensing, which makes the process of dispensing automatic. Compared with the original manual dispensing, it greatly improves the work efficiency. There are applications in the production field. [0003] Existing glue dispensers generally include: a compressed air source, a main compressed air pipeline, an auxiliary compressed air pipeline, a glue gun and a timing controller. The main compressed air pipeline is provided with a pressure regulating valve, a pressure gauge and a three-way valve in sequence, and one end thereof is connected with the compressed air source, and the other end is connected with the hose. The auxiliary compressed air pipeline connected with the compressed air source is provide...
