The application solutions of Automatic dispensing machines in the LCD/OLED screens industry need to address the differentiated requirements of these two technologies. Below is a detailed analysis from core application areas and technological innovation perspectives:

 

LCD Screen Dispensing Solutions

1.Bezel Sealing

● Function: Achieve secure adhesion between the screen and middle frame via dispensing, enhancing structural strength while preventing moisture/dust ingress .

● Technical Implementation: CCD vision-guided dispensers with sub-pixel positioning accuracy (±0.01mm) adapt to varying sizes of LCD modules;

 multi-axis collaboration enables continuous bead application for complex trajectories .

 

2.Backlight Unit Encapsulation

● Function: Fixate light guides and reflective films with uniform adhesive layers to avoid optical performance degradation .

Technical Implementation: High-speed dispensers rapidly apply even coatings across large areas, balancing efficiency and precision; supports multiple adhesive types (e.g., silicone, epoxy) with pressure control systems preventing drippage of low-viscosity materials .

Second Intelligent In-line Automated Glue Dispensing Machine SEC-DH400L adopts an integrated mineral casting design, with ultra-high precision and super stability, powerful expansion capabilities, and can realize ion cleaning, dispensing, detection, UV exposure and other functions;

Adopting a gantry structure, it can bear large loads, stable structure, and a powerful CCD visual positioning system, which can meet the requirements of Mark point positioning, edge positioning, and 3D scanning positioning; strong scalability, and can expand AOI detection 3D detection, UV exposure curing and other functions;

Strong platform compatibility, contact and non-contact dispensing, single-head and multi-head synchronous dispensing, automatic compensation and adjustment of double-head spacing, five-axis dispensing function based on needle A/R displacement, etc.

 

 

3.Notch Area Light Blocking

● Function: Seal gaps between lower polarizers and backlight modules to prevent light leakage interfering front camera imaging .

● Technical Implementation: Precision nozzles paired with micro-dosage control target narrow gap regions accurately.

 

4.Flexible Display Lamination

 

● Function: Ensures reliable curved bonding for foldable devices through dynamic angle/pressure adjustments .

● Technical Implementation: Four-axis dispensers coordinated with rotary motion resolve uneven adhesive distribution on irregular surfaces.

 

Second Intelligent has played an important role in theresearch, development, manufacturing, pre-sales and after-sales services of fluid dispensing robot, potting and coating solutions which range from various types of automatic fluid dispensing, potting, two-component potting machines and coating machines with desktop, free-standing, inline or cobot combined systems, and widely used in global electrical, electronics, home appliances, automobile, telecom, pharmaceutical, automotive electronics, semiconductor, aerospace, LED and more.
