Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing equipment, in particular to an adjustable annular plastic part glue dispensing device. 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 glue leakage, and no glue 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] Ring-shaped plastic parts are needed in the assembly process of industrial robots. During the production process, the surface of the ring-shaped plastic parts needs to be coated with glue to achieve a sealing effect. However, the current ring-shaped plastic part dispensing equipment is not convenient for dispensing glue on plastic parts of different diameters. At the same time, the method of fixing the plastic parts with bolts is rather cumbersome. Therefore, we propose an adjustable ring-shaped plastic part dispensing device to solve the above problems.
