Overview of the Vision Dispensing Machine

The vision dispensing machine uses a 360° panoramic automatic inspection system. Its working area and dispensing accuracy can be customized according to the specific product requirements. The machine offers powerful recognition capabilities and can quickly dispense adhesive on complex and irregular products with extremely high precision.

We typically use imported industrial cameras with image resolutions of up to 8 megapixels, ensuring clear image capture and accurate positioning. The high-resolution vision system enables faster dispensing speeds and more precise glue application. Every company can customize the machine configuration based on its products and production capacity.

Floor-standing vision dispensing machines are generally available in two types:

• Panoramic Vision Dispensing Machines

• Local Vision Dispensing Machines

Inline vision dispensing machines are designed for fully automated production and can achieve unmanned operation. For assistance in selecting the most suitable vision dispensing solution, customers are welcome to contact our technical team.

Intelligent Vision-Guided Dispensing Process

Products can be placed randomly on the machine worktable without precise positioning fixtures. The vision dispensing system automatically identifies the product location and generates the dispensing path. It can perform dots, lines, circles, S-shaped patterns, and other customized dispensing trajectories.

The machine can also automatically identify defective products or parts that do not require adhesive application. Combined with multi-head dispensing technology, it delivers higher efficiency, faster production speeds, and significant labor cost savings.

Compared with manual dispensing, a vision dispensing machine can accurately dispense extremely small amounts of adhesive into narrow gaps and complex areas that are difficult or impossible for manual operators to reach.

The machine supports dual-station automatic cycling and can operate continuously 24 hours a day, greatly improving production efficiency. Equipped with high-speed dispensing valves, it eliminates the need for precision fixtures. Once the vision system scans and captures the product image, the dispensing program is generated automatically, allowing the machine to start dispensing immediately.

The system can also automatically detect defective products or components that do not require adhesive, helping manufacturers reduce production costs and improve product consistency.

Glue Supply Principle of the Vision Dispensing Machine

The vision dispensing machine adopts a metering and dispensing glue supply system.

• Component A is metered independently.

• Component B is metered independently.

• Both components are delivered separately to the dispensing valve, where they are mixed immediately before dispensing.

This design eliminates concerns about adhesive curing inside the material tank.

The following parameters can be adjusted directly through the machine interface:

• Dispensing volume

• Bead width

• Dispensing speed

• Dispensing duration

• Glue shut-off time

The system ensures stable glue output with excellent consistency and prevents dripping or leakage.

Metering Pump Configurations

1. Gear Pump Configuration

A gear pump transfers liquid by changing the working volume formed between the pump housing and meshing gears while maintaining stable pressure.

Its main structure consists of:

• Two precision gears

• Sealing plates

• Pump body

• Screw rods

• Front and rear covers

These components form two sealed chambers. When the gears rotate, a vacuum is created on the inlet side, drawing liquid into the pump. The liquid is then transported to the discharge side and pushed into the delivery pipeline.

The flow rate depends on the clearance between the gears and is controlled by the motor speed. Higher motor speed results in higher flow output. The outlet pressure is determined primarily by the resistance and pressure requirements of the dispensing system.

2. Screw Pump Configuration

A screw pump operates through the interaction between the screw rotor and sealing elements, enabling high-pressure delivery.

Key advantages include:

• Excellent corrosion resistance

• High-temperature resistance

• Strong tolerance to impurities and fillers

As the screw rotates, sealed chambers continuously form at the suction end. The adhesive is trapped within these chambers and transported axially along the screw toward the discharge end. The process is similar to a nut moving forward along a rotating threaded shaft. This continuous conveying action is the fundamental working principle of a screw pump.

Vision Dispensing Valve Configuration

The machine is equipped with a dual-component instant suction-back dispensing valve, which offers:

• Fast adhesive cut-off

• Stable dispensing performance

• No dripping or leakage

The internal sealing components are manufactured from high-performance materials that provide excellent wear resistance and high-temperature resistance.

In addition, a high-speed servo mixing motor is integrated into the valve assembly to ensure thorough mixing of the two adhesive components, guaranteeing consistent adhesive quality and dispensing accuracy.
