A vacuum injection mechanism of a digital tube double-liquid automatic glue filling machine

Abstract

The invention discloses a vacuum injecting mechanism for a nixie tube dual-liquid automatic glue pouring machine. The vacuum injecting mechanism comprises a box cavity body; side covers are mounted onthe two sides of the box cavity body in a sealed manner; an L-shaped connecting plate is mounted at the upper end of the box cavity body; the upper end of the L-shaped connecting plate is connected with a moving plate in a sliding manner; and the moving plate is mounted on a moving plate of an air cylinder in the glue pouring machine. According to the vacuum injecting mechanism, the side covers are fixed to the box cavity body through matched design of a three-way pipe and a glue inlet pipe; meanwhile, the sealing property between the side covers and the box cavity body is ensured; the problem that the box cavity body is inconvenient to clean is solved; the function of pouring two types of glue simultaneously is realized through the design of the two side plates; the glue pouring operation period of a product is greatly shortened; and through matched design of a vacuum pipe, the box cavity body and the L-shaped connecting plate, the problem about air bubbles in glue pouring of a product is solved.

Description

technical field [0001] The invention belongs to the field of digital tube production, and in particular relates to an automatic glue filling machine, more specifically a vacuum injection mechanism of a digital tube double-liquid automatic glue filling machine. Background technique [0002] The glue filling machine is an automatic machine that controls the fluid, and drips, coats, and pots the liquid on the surface of the product or inside the product, so that it can achieve the functions of sealing, fixing, and waterproofing. Generally, it is a double-group part glue. The glue filling machine is often used for glue filling of LED display screen, glue filling of LED energy-saving lamp, glue filling of LED power supply, LED light bar, glue filling of computer power supply, glue filling of relay module, glue filling of sensor, glue filling of PCB board, glue filling of solar panel , Coil inductance glue filling, soft light strip glue filling, point light source glue filling, L...

AI Technical Summary

Problems solved by technology

[0003] During the processing of digital tubes, glue filling is an essential production process. In the current production process of digital tubes, there are some deviations between the injection mechanism and the actual working position during injection. Usually, the product contains a certain amount due to insufficient vacuum. Bubbles will affect the quality and performance of the product. At the same time, due to the mixing of two-component glue in the injection mechanism, regular cleaning and cleaning are required. Due to the problem of sealing, the components of the existing injection mechanism are welded. Thereby bringing great inconvenience for cleaning
