Seal Schedule Settings (Part 2) - Middle of Dispense

In this tech short, we will go over the critical seal schedule settings that influence the middle of a dispense process. These settings play a key role in achieving consistent bead quality and optimizing flow control during robotic dispensing. Whether you are fine-tuning for accuracy or troubleshooting performance issues, understanding these parameters will help you improve results and reduce variability. We start by reviewing the generic dispense process signal timing diagram and identifying the five main settings that impact the middle of a bead. Each setting serves a specific purpose in controlling flow rate and adapting to changes in robot speed or path geometry. By the end of this session, you will have a clear understanding of how these adjustments work together to maintain precision.

Key Requirements for Effective Adjustment:

• SpotTool+ software properly configured for dispense operations
• A working knowledge of seal schedule settings and their role in bead formation
• Dispenser I/O mapped and verified for accurate signal communication

What You Will Learn:

• How Flow Rate determines bead size and why it is the most critical setting
• The role of Equipment Anticipation Time in preparing for speed changes
• Why Additional Anticipation Time is essential for reducing flow rates effectively
• How to apply Correction Factor for individual seal schedule accuracy
• When to use Correction Bias for corners and slower robot speeds
• The impact of TCP height on bead shape and quality

We will also touch on different flow rate types and how they influence dispense performance. By understanding these concepts, you can make informed adjustments that improve consistency and efficiency in your robotic dispense operations.
