Selecting the Right Adhesive Dispense & Curing Technologies

Choosing the appropriate curing method is a critical aspect of adhesive selection, as it directly impacts the strength, durability, and performance of bonded assemblies. The curing process transforms adhesives from liquid or semi-liquid to solid, creating strong bonds. Several factors must be considered when selecting the proper curing method.

Firstly, understanding the adhesive’s curing mechanism is essential. Adhesives can cure through various methods such as chemical reactions, heat, UV light, moisture, or a combination of these.

Each method also has its requirements and considerations. For instance, heat curing may involve subjecting the adhesive to specific temperatures for a designated period, while UV curing utilizes ultraviolet light to initiate and complete the curing process rapidly.

Integrating Advanced Robotics & Motion Control

For highly precise or complex dispense objectives, sophisticated motion control must ensure that part positioning, placement, and movement are coordinated perfectly with the dispensing process.

By integrating the adhesive dispense system with the overall control system of the production line, manufacturers can achieve synchronized and coordinated operations. This integration allows for real-time communication, data exchange, and control signals between the adhesive dispense system and other equipment, such as assembly stations or curing ovens.

Incorporating robotics into adhesive dispense systems brings a new level of accuracy, repeatability, and flexibility to the process. With programmable motion control, robots can precisely control the dispensing path, nozzle positioning, and dispense parameters, ensuring accurate and repeatable adhesive application.

Working from your requirements, we help you achieve the targeted degree of accuracy for part placement.

Integrating Advanced Vision & Inspection Systems

The integration of advanced vision and inspection systems into adhesive dispense processes has become a game-changer, significantly elevating the quality and reliability of bond formation. By integrating vision systems, manufacturers can ensure precise alignment of dispense paths and patterns, detecting any deviations or errors that may compromise bond strength.

These systems can also identify issues such as air bubbles, voids, or uneven dispense, allowing for immediate corrective actions. The real-time feedback provided by vision systems empowers operators to make adjustments on the fly, ensuring consistent, high-quality adhesive application and minimizing the risk of defects or rework.

> Select the right vision technology for your specific application, including profilometer laser scanners and high resolution camera systems
> Configure vision systems to accurately locate and scan parts and surfaces, from 2D to 3D scanning
> Coordinate and integrate vision systems with motion and dispense systems for dispense operations onto parts, surfaces, contours, and geometries

Reducing Manual Maintenance Procedure Overhead

One of the most common and time-consuming challenges we hear about is the high level of maintenance required for adhesive dispense manufacturing.

Automation plays a crucial role in reducing manual overhead and enhancing the efficiency of adhesive dispense operations. By integrating automated systems, such as robotic arms or gantries, manufacturers can automate repetitive tasks, such as adhesive dispensing or nozzle cleaning, eliminating the need for manual intervention and reducing the associated labor costs.
