What is an Automatic Screw Feeder?

An automatic screw feeder is a device that automates the screw feeding process with precision and efficiency. It is commonly used in component assembly, PCB manufacturing, and equipment production.

The main function of an automatic screw feeder is to organize and deliver screws in a fixed orientation quickly and accurately, allowing operators or robots to pick them up easily and efficiently.

How a Screw Feeder works?

The screw feeder operates by automatically transporting screws from the storage chamber to the screw dispensing position via mechanical structures.

When screws are loaded into the hopper in bulk, the system automatically pushes them along a designated path towards the dispensing exit. At this point, the screw stops with its head facing upwards, ready for tools such as electric screwdrivers, automatic screwdrivers, or robotic arms to pick up and fasten them in the required locations. 

This system ensures precise screw supply, improving fastening accuracy and speed in assembly lines, reducing errors, and enhancing efficiency and throughput.

5 Outstanding Advantages of an Automatic Screw Feeder

1. High Flexibility

Automatic screw feeders can easily change rails to accommodate various screw sizes. Screws are fed horizontally, ensuring smooth and consistent delivery.

Temas is the official distributor of Janome Automatic Screw Feeders, which support multiple screw types ranging from M1.0 to M5.0. Additionally, with two design options—handheld screwdriver-compatible feeders and robot-compatible feeders—you can flexibly choose the screw feeder that best suits your application.

Janome screw feeders also provide multiple jig plate options with different orientations and heights when used with desktop robots, offering users greater flexibility and adaptability in various assembly scenarios.

The Janome screw feeder supports a variety of screws, including magnetic screws, non-magnetic screws, and even hexagonal-head screws.

2. Overload Protection Function

A key advantage of automatic screw feeders is their built-in overload protection, which safeguards the machine for stable and reliable operation. 

If too many screws accumulate in the pick-up chamber or a screw gets jammed, the motor automatically reverses for a short duration to self-adjust.

If the issue persists and the screw feeder does not return to normal operation, the built-in safety function will cut off the motor’s power supply, preventing damage and protecting the device

3. External Output Signal

The automatic screw feeder is designed with an external output signal as a standard feature, ensuring continuous and concentrated screw supply during assembly processes. 

For handheld applications, the output signal is triggered when a screw is successfully picked up. For robotic applications, the output signal provides real-time updates on screw availability or shortage, enabling precise and efficient assembly control.

4. Space-Saving Design & Long Lifespan

With a compact design, the screw feeder is optimized for seamless integration with robots and easy installation in tight spaces, maximizing workspace efficiency.

Its superior durability ensures a lifespan twice as long as other products on the market, delivering stable and long-term performance for production lines.

5. Reduced Operating Time & Increased Productivity

Automatic screw feeders significantly reduce fastening time and manual handling efforts. The system can filter out defective screws and minimize assembly errors. 

This system also allows for adjustable settings to accommodate different screw sizes and lengths, simplifying assembly for workers, expanding automation capabilities for robots, and boosting productivity in industrial machinery assembly.
