Gripper vs Vacuum Nozzle: Which Is Better for SMT Spring Pickup
| Product Name | Gripper Nozzle |
|---|---|
| Model Number | FE01, FE02 |
| Used for component | Special SMT component like spring, Irregularly shaped components |
| Apply for pick and place head | Multi-function placement head, Odd-shaped head (multi-function head) |
[ GXH Multi-Function Head ]
│
[ Gripper Mechanism ] ← pneumatic or mechanical drive
/ \ ← two or more gripper jaws
[ Spring ] ← grip D1 or D2 outer diameter
▄ D2 = φ0.6
█ D1 = φ1.5
| Machine Model | Placement Head Type | Nozzle Quantity | Applicable Component Size | Placement Accuracy | Gripper Nozzle Supported |
|---|---|---|---|---|---|
| GXH-3 | High-speed placement head | 12 nozzles | 0.6 × 0.3 mm (0201) ~ 44 × 44 mm | ±0.01 mm | ❌ No |
| GXH-3 | Multi-function placement head | 3 nozzles | Wide range of components including odd-shaped parts | ±0.01 mm | ✅ Yes |
| GXH-1S | High-speed head | 12 nozzles | 0402 (optional) ~ 44 × 44 mm | ±0.05 mm (up to ±0.035 mm with special calibration) | ❌ No |
| GXH-1S | Odd-shaped head (multi-function head) | 3 nozzles | 3216 ~ □55 mm, connectors up to 100 × 26 mm, thickness ≤ 25.4 mm | ±0.05 mm | ✅ Yes |
| G5S | High-speed placement head | 15 nozzles | 0402 ~ □44 mm | ±25 μm | ❌ No |
| G5S | Multi-function placement head | 3 nozzles | Components within □55 mm, connectors up to 100 × 26 mm, thickness ≤ 25.4 mm | ±15 μm | ✅ Yes |
| Problem | Vacuum Nozzle | Gripper Nozzle |
|---|---|---|
| D2 end face is too small (φ0.6 mm) | Insufficient suction, parts easily drop | Mechanical clamping, not dependent on end surface |
| Eccentric spring (0.4 mm offset) | Difficult alignment, easy to jam | Clamp jaws can adapt to eccentricity |
| Hollow structure | Vacuum leakage likely | Clamps hold the outer diameter, not affected by hollow structure |
| Feeding direction (D2 facing up) | Can only pick the small end surface | Clamp jaws can grip from the side |
