Working Principle
-
Screw Loading:
- Screws are either manually poured into a hopper or fed from bulk storage.
- The hopper uses vibration or a rotating drum to move the screws into position.
-
Screw Orientation & Sorting:
- The system orients screws head-up or tip-up, depending on the requirement.
- Incorrectly positioned screws are recycled back into the hopper.
-
Feeding Mechanism:
- Once correctly oriented, screws are fed one by one into a guide rail or tube.
- This is typically done using vibration, air pressure (blow feeding), or a mechanical pusher (suction feeding).
-
Screw Presentation:
- The screw is delivered to a fixed or handheld driver head.
- In handheld systems, the operator positions the driver; in automated setups, a robotic arm may do this.
-
Screw Tightening:
- The screwdriver engages with the screw and drives it into the target material.
- Torque and depth can be controlled automatically for consistency.
⚙️ Types of Feeding Systems
- Blow Type: Uses air pressure to blow the screw through a tube to the screwdriver.
- Suction Type: Uses vacuum suction to carry screws.
- Pick-and-Place Type: A robotic arm picks up each screw and places it.
✅ Key Features
- High-speed feeding (up to 60 screws/min or more)
- Suitable for various screw types (Phillips, hex, torx, etc.)
- Programmable torque and depth settings
- Reduces manual handling, improving efficiency and ergonomics
