Precision Parts- Multi-Head Suction Nozzle

In chip processing, the precision Multi-head nozzle (also known as Jumper Pickup Nozzle) is used for vacuum adsorption, precise handling, and positioning of tiny chips or components, ensuring positional accuracy in bonding, mounting, and other processes.

Pain Point Analysis:
* Insufficient Adsorption: The current nozzles exist unstable vacuum suction, causing chip offset or falling off, which affects the yield.
* Wear Issues: Under high-frequent operations, the end face of the nozzle is worn due to friction with the chips, resulting in vacuum leaks and decreased adsorption performance.

Solutions:
– Structural Design: Adopt a tapered inner cavity design and optimize airflow paths through fluid simulation to enhance local vacuum pressure by over 20%.
– Material Upgrade: Use martensitic stainless steel SUS440C (HRC≥40) to ensure wear resistance and corrosion resistance.
– Surface Treatment: Apply precision hard chrome plating to further reduce the friction coefficient.

Final Effects:
Improved Adsorption Efficiency: The chip pickup success rate increased from 90% to 99.9%.
Cost Effectiveness: Yield increased by 2.7%, and rework cost decreased by 40%.
