Nozzle Manufacturer Analyzes Causes and Solutions for SMT Nozzle Pickup Failure and Errors

Before publishing this article, many people have asked about the causes of SMT nozzle pickup failure and errors. Below, the nozzle manufacturer intends to share the corresponding solutions.

1. Multiple Causes for Nozzle Pickup Failure

Key factors include coordinate deviations, insufficient vacuum pressure, and improper Z-axis height.

2. Insufficient Vacuum Pressure

Common triggers are contaminated filters or misaligned brackets.

3. Component or Packaging Issues

Check if the component is overly heavy, stuck too tightly in the tape pocket, or if the contact surface between the component and the nozzle is uneven.

4. Nozzle Wear and Damage

Nozzle wear, deformation, clogging, or damage leads to insufficient air pressure, resulting in failure to pick up components. Regularly inspect the nozzle's wear level and replace severely damaged ones promptly.

5. Improper Feeder or Component Tray Placement

Ensure the feeder or component tray is correctly positioned.

Corresponding Solutions

For optimal component pickup by the SMT nozzle, the center of the component, the center of the nozzle, and the spatial center of the captured image must align. The adjustment of the optical vision system essentially compensates for deviations caused by misalignment in actual working conditions.

Different surface mount components require specific nozzles for pickup. Nearly all nozzles are equipped with a reflective background, which provides a favorable backdrop during image acquisition. This ensures accurate highlighting of target information during image processing—when capturing images, the nozzle acts as a background to enhance the contrast of the component's image, making it clearer and more distinguishable.
