In modern automated production, an automatic screw-tightening station plays a vital role. It not only boosts production speed but also guarantees consistent quality and reliability. Below is a breakdown of the main building blocks of such a station, illustrated with Danikor solutions.

1. Screw Feeder – Orderly Supply

The screw feeder is the foundation of the whole system. It takes randomly oriented screws and lines them up, then delivers them to the tightening screwdriver via a blow tube. Three common feeder types are:

• Vibratory Bowl – general purpose

• Disc Feeder – ideal for micro screws

• Step Feeder – Danikor’s flagship for M2–M24 screws, capable of long-screw handling and low-noise operation.

  

2. Tightening Module – Accurate Execution

The tightening module holds and guides the screw while a cylinder or servo motor drives the tool to apply torque. Danikor offers:

• Universal modules – compact, quick-change heads

 

• Offset / 90° modules – for tight spaces

• Floating modules – compensate for hole position errors up to 2.5 mm

3. Motion System – Precise Positioning

• 3-Axis Cartesian Platform – high-precision ball-screw axes (X-Y-Z) deliver repeatable placement within 0.1 mm.

• 6-Axis Robot – Danikor integrates directly with major robot brands, enabling complex paths for multi-angle or multi-location tightening.
