If you’ve ever tried picking up small eccentric springs with a standard SMT vacuum nozzle, you probably know the problem: parts drop, misalign, or get stuck.
Recently we worked on a case involving a GXH pick-and-place machine where the spring had:
• A very small end face (φ0.6mm)
• 0.4mm eccentric offset
• Hollow structure
• Feeding direction with the small end facing up
A traditional vacuum nozzle simply couldn’t handle it.
So we designed a custom gripper-style SMT nozzle to clamp the spring instead of relying on vacuum. The pickup became much more stable.
I summarized the problem and solution in this short article:
If you’re dealing with difficult SMT components like springs or special parts, this might help.
