Applications of Automatic Dispenser Machines in LCD/OLED Screens Industry Solutions？

 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 .

Automatic In-line PCB Glue Dispensing Machine SEC-DH400L

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.

Common Causes of Scattered Dots in Glue Dispensing Machines and Second Intelligent’s Solutions

图片
  As a leading enterprise in the fluid application field in China, Shenzhen Second Intelligent Equipment Co., Ltd. (referred to as "S econd  Intelligent") has been dedicated to dispensing technology for nearly 20 years. Its products are widely used in 3C electronics, new energy, biomedicine, and other industries. During the dispensing process, "scattered dots" and "splashing" are core defects that affect product yield. This article analyzes the causes of scattered dots and proposes systematic solutions based on Second  Intelligent’s technical expertise and industry experience. 1 . Common Causes and Mechanisms of Scattered Dots l  Temperature Fluctuations Causing Viscosity Changes Adhesives are temperature-sensitive, and ambient temperature fluctuations significantly alter their viscosity. For example, epoxy resin becomes less viscous and more fluid when temperatures rise. Failure to adjust dispensing parameters in real-time may lead to trajectory deviation...

Thermally Conductive Paste Dispensing– The Hot Spot Solution Application

图片
  The application of dispensing thermally conductive paste is a key technology for solving the “hot spot” problem in electronic devices. Below, I will systematically explain it to you, including its principles, solutions, application cases, and best practices. 1.Core Concept: Why Apply Thermally Conductive Paste? — From “Surface Heat Dissipation” to “Precision Heat Dissipation” Traditional methods of applying thermal paste using scraping or manual application have several problems: ● Uneven Thickness: Easily creates areas of varying thickness, affecting overall heat transfer efficiency. ● Air Bubbles: Manual application easily introduces air, forming insulating bubbles. ● Inability to Handle Complex Structures: Difficult to achieve uniform coverage for chips with inconsistent heights or areas containing components. The core advantages of thermal paste application technology lie in its precision, controllability, and automation. It can: 1.Precise Positioning:  Accurately apply ...
