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.
