Seal Schedule Settings (Part 3) - End of Dispense

In this session, we will go over the critical seal schedule settings that influence how a dispense process ends and transitions into the next bead. These adjustments are essential for maintaining precision, preventing pressure spikes, and ensuring consistent quality in automated dispensing applications. We start by reviewing the generic signal timing diagram from the SpotTool+ manual, highlighting the key parameters that control the end of a dispense. From there, we break down three important settings:

1. Gun Off Anticipation Time – Learn how this setting determines when the valve closes relative to the taught point and why it matters for bead accuracy.
2. Equipment Anticipation Time – Understand how this timing helps the system slow down before the valve closes, avoiding high-pressure situations.
3. Seal End Offset Time – Explore how this fine-tuning option stabilizes pressure and improves stitching performance.

Throughout the video, we will explain how these settings interact and provide practical examples of ideal versus incorrect adjustments. You’ll also see why timing changes can impact corner performance and how to optimize for smooth transitions between beads.

Requirements for Applying These Concepts:

• Familiarity with SpotTool+ or similar dispense control software
• Basic understanding of robotic dispense processes
• Access to system configuration tools for timing adjustments

What You Will Learn:

• How to interpret the dispense process signal timing diagram
• The role of anticipation times in controlling valve behavior
• Techniques for preventing pressure spikes at the end of a dispense
• Best practices for stitching applications and PrePressure optimization

By the end of this session, you’ll have a clear understanding of how to fine-tune seal schedule settings for improved dispense accuracy and system stability. If you’re looking to enhance your process control and reduce variability, this video is a must-watch.
