Description

Technical Field

[0002] In the production process, a glue dispensing device is often used to apply glue on the surface of an object. At present, the glue dispensing devices on the market generally rotate and dispense glue by driving an inclined glue dispensing nozzle to achieve uniform glue coating on the object. However, the inclined installation angle of the glue dispensing nozzle of the existing glue dispensing device is usually fixed, resulting in a fixed circumference size of the glue dispensing nozzle rotating to dispense glue. When it is necessary to apply rubber rings of different circumference sizes, it is necessary to replace glue dispensing nozzles with other inclined angles, especially when different parts of the same object need to apply rubber rings of different circumference sizes. If the glue dispensing nozzle is replaced frequently, it will take a long time to disassemble and install the glue dispensing nozzle, and the glue coating production efficiency is low and the flexibility is poor, which makes it difficult to meet the actual glue coating production needs.
