Technical Q&A: Automatic Screwdriving Machine

1. Is the screw feeding process stable in Everprecision’s automatic screw driving machines?
2. How does the system detect stripped threads or high screws (floating screws)?
3. Is it difficult to switch product specifications (screw sizes)?
4. Is production data traceable (Industry 4.0)?


1. Is the screw feeding process stable in Everprecision’s automatic screw driving machines?

A： Our machines utilize a screw feeder equipped with high-precision track designs. It uses physical screening based on the screw head and geometry to ensure screws are automatically aligned in a fixed orientation during transport. A specialized indexing mechanism then controls the output to one screw at a time, ensuring maximum stability and consistency during the fastening process.


2. How does the system detect stripped threads or high screws (floating screws)?

A： This is a critical factor for quality control. Our systems can be equipped with an Intelligent Servo Screwdriver, which provides real-time monitoring of both torque and angle (rotation count). If the rotation count is insufficient, the system identifies it as a "high screw" and triggers an error signal. This ensures every screw is fully seated and properly fastened, rather than simply reaching a torque threshold.


3. Is it difficult to switch product specifications (screw sizes)?

A： Many users worry about the difficulty of changeovers. Everprecision’s intuitive software interface allows for quick transitions; users simply switch to a pre-saved program profile. By swapping out modular tracks and indexing discs tailored to different screw sizes, the entire changeover process can typically be completed within 15 minutes, providing excellent production flexibility.


4. Is production data traceable (Industry 4.0)?

A： To meet the demands of modern management, Everprecision automatic screw driving machines are equipped with IoT connectivity (MQTT, HTTP, FTP). Production data is recorded and exported in a "Standard Data Field Format." This includes information such as Product SN, Operator ID, screw count, fastening status, and fastening torque (when paired with an intelligent screwdriver). Customers can extract
