Product Overview

Key Features

  • • Area camera (image processing) classifies part type and orientation
  • • Ultrasonic motor gripper enables vibration-free, heat-free picking
  • • AVW function removes tip adhesion (Anti Van der Waals force)
  • • Supports both chip-part and pin-part sorting/alignment workflows
  • • Desktop form factor for easier installation
  • • Compatible with gripper head series (TGH-1011 / 1021 / 1031)

Operation Flow

Chip Parts
① Separate
② Recognize
③ Grip
④ Verify Pick
⑤ Remove & Align
Pin Parts
① Separate
② Recognize
③ Grip
④ Level & Re-grip
⑤ Remove & Align

For chip parts, MPPS runs a 6-step sequence from diffusion to alignment, reducing mis-picks, orientation errors, and residual sticking at the same time.

1. Diffusion

Vibration disperses randomly piled parts (table specification can be customized)

2. Recognition

Image processing identifies position and shape

5. Adhesion Removal

AVW removes tip adhesion for accurate transfer

Chip part alignment

6. Alignment

High-precision alignment to fixed position and orientation (tray can be customized)

For pin parts, MPPS adds horizontal correction and re-gripping to stabilize posture of thin/long workpieces before final alignment or insertion.

1. Pin Diffusion

Pins are separated and dispersed by vibration

2. Pin Recognition

Image processing identifies position and posture

3. Gripping

Ultrasonic motor gripper performs picking

4. Horizontal Correction & Re-grip

Place once on jig, then re-grip at proper position

5

5. Adhesion Removal & Alignment

After AVW removal, align pins (or insert to jig when needed)

Pin Options / Stabilization

Pin Horizontal Correction Flow

Overlapping Pins

(Re-grip even if not overlapping)

→ When pins overlap,
→ the grip is not horizontal
→ place on a flat jig once
→ re-grip at the correct position
→ proceed to the next step

AVW Unit — Anti Van der Waals Force

Micro parts can cling to gripper tips due to Van der Waals force — neither magnetic nor electrostatic, but powerful at micro scale. The AVW unit eliminates this adhesion, enabling accurate transfer and alignment.
