Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing devices, in particular to a glue dispensing device which is convenient for replacing a glue nozzle. Background Art

[0002] Glue dispensing machine is also called glue coating machine, glue dripping machine, glue spraying machine, glue filling machine, etc. It is specially used to control fluids. It is an automated machine that drips and applies fluids on the surface or inside of products. It can achieve three-dimensional and four-dimensional path dispensing, precise positioning, precise glue control, no drawing, no leakage, and no dripping. Glue dispensing machine is mainly used for glue, paint and other liquids in product processes to accurately point, inject, apply and drip at the precise position of each product. It can be used to achieve dotting, drawing lines, circles or arcs.

[0003] Most of the existing glue dispensing machines are fixed-type glue dispensing during operation. For example, when dispensing glue on a circuit board, there are many places where glue needs to be dispensed. Since the glue dispensing machine is generally fixed, the circuit board needs to be moved frequently, and the frequent movement of the circuit board is likely to cause collision damage to the circuit board. In addition, the fixed glue dispensing efficiency is low, and it is easy to have certain limitations for mass-produced products. In addition, the glue nozzle is easily damaged and is generally threaded. Due to the nature of the glue, the glue nozzle and the rubber hose are easily fixed, which makes it inconvenient to disassemble and replace. Utility Model Content
