Two-component servo glue shaft dispensing case study: AB adhesive bonding application for curved glass displays?

The application of “two-component servo glue shaft dispensing” technology to the bonding of curved glass displays using A/B adhesives represents a highly precise process step in current consumer electronics manufacturing.

 

Ι.Analysis of the key elements of the case::

 

● Core Process:Two-component servo glue shaft adhesive dispensing system. This is a high-precision automated dispensing machine technology that uses a servo motor to drive a plunger, precisely controlling the mixing ratio (e.g., 1:1) and dispensing volume of the A and B components. After uniform mixing in the mixing tube, the adhesive is applied to the designated location. Its advantages include precise mixing ratios (with errors controllable within ±1.5%), stable dispensing, and a clean, string-free cut-off, making it highly suitable for high-viscosity, high-filler adhesives.

 


Benchtop Desktop Glue Dispensing Robot machine SEC-E480

 

 

This is the Second Intelligent SEC-E480 desktop dispensing machine, which features one-piece casting, strong structure, and stable operation; smaller size and larger stroke. Adopting the transmission method of stepper motor plus synchronous belt, it has the advantages of low cost and low noise! Flexible matching of different glue supply/control systems; realize dispensing of different products with different processes. In addition, adopting stepper motor + precision imported synchronous belt drive, it can ensure high accuracy and have higher cost performance

 

● Key Materials:AB Adhesive. Here, “AB adhesive” is a broad term; in display bonding applications, it typically refers to the following types:

OCA (Optical Clear Adhesive): Used for bonding optical layers within the display, requiring high transparency without affecting display performance. For example, there is an AB adhesive specifically designed for curved screens, whose structure includes an OCA layer and a soft substrate layer to adapt to the curved shape without causing bubbles.

Structural AB Adhesive: Used for filling and structural bonding between the glass cover plate and the display module. For example, in a curved screen lamination process, adhesives from the same system are used: uncured Part A is applied as a temporary “dam” to prevent adhesive overflow, followed by Part A mixed with Part B (curing agent) as the top coat for filling and bonding.


Second Intelligent has strong solution and technical service capabilities, and will provide customized automatic fluid dispensing and glue filling solutions to customers based on their adhesive characteristics, production process requirements, production capacity requirements, factory space, and other comprehensive factors. At the same time, in the global market, we will provide comprehensive solutions and technical support services to global customers through distributors, agents, and our headquarters’ 50+technical team.
