[0002] High-speed glue dispensing machine is a precision fluid control equipment used for precision coating, glue dripping and glue spraying. It adopts advanced control technology and precision glue spraying head, and can achieve a dispensing speed of up to hundreds of times per second. It has the advantages of high production efficiency, high precision and good stability, labor saving and cost reduction. It is widely used in electronics, automobile, aviation and other industries.

[0003] When using the existing glue dispensing equipment, a common problem is that the glue dispensing head is blocked by solid residues inside the colloid, which causes the colloid to easily accumulate inside the glue dispensing tube. When the glue dispensing equipment stops using, excess glue will also accumulate inside the glue dispensing tube. If it is not cleaned in time, it may easily solidify inside the glue dispensing head, affecting the glue dispensing effect. In addition, the existing glue dispensing equipment is usually only suitable for straight line glue dispensing, which is inconvenient for glue dispensing on arc-shaped workpieces and has a limited scope of use. Therefore, a glue dispensing device with anti-glue accumulation for a glue dispensing machine is proposed. Summary of the invention
