Abstract

The invention discloses a digital pneumatic quantitative glue injection system which comprises a glue cylinder. An outlet of the glue cylinder is connected with a glue nozzle through a glue injection pipe; the glue cylinder is fixedly connected to a frame; a bottom plate is fixed below the frame; a cylinder is arranged on the bottom plate; a moving rack is connected with the outer end of a piston rod matched with the cylinder; a slideway is formed between the moving rack and the bottom plate; the glue nozzle is mounted at the front end of the moving rack; and a cavity in the rear part of a glue pushing piston inside the glue cylinder is connected with a pneumatic control device comprising a quantitative valve through an air pipe connecting port. The glue injection mechanism has the advantages of high accuracy, timeliness, quantification, high glue injection quality and high efficiency and is free of checking during glue injection.

Description

technical field [0001] The invention relates to a glue injection mechanism, in particular to a digital pneumatic quantitative glue injection system. Background technique [0002] In the process of aircraft manufacturing and assembly, some parts need to be partially injected with glue. At present, manual glue injection is used. The glue injection tools include rubber cartridges. There is a glue injection pipe connected to the front outlet of the glue cartridge. The glue injection pipe is connected to the nozzle. There is a piston inside, and the push rod connected with the piston rod pushes the piston forward to achieve the purpose of glue injection. The glue injection mechanism of this structure is very random, the amount of glue injection is not easy to control, the glue injection is troublesome, time-consuming and laborious, the efficiency is low, and the appearance effect after glue injection is poor, and manual inspection is required. Contents of the invention [0003...
