Classification of Automatic Screw Locking Machines: From Working Principles to Industrial Applications

By Feeding Mechanism

1 ​​Vacuum Adsorption Type​​

• ​​Principle​​: Uses vacuum suction for screw delivery, suitable for non-magnetic screws (e.g., plastic or copper) and precision assembly
• ​​Applications​​: High-stability scenarios requiring diverse screw sizes

2 ​​Pneumatic Blowing Type​​

• ​​Principle​​: Airflow-driven continuous feeding, faster than adsorption but limited to screws with length-to-diameter ratios 1.5
• ​​Applications​​: High-speed production of standardized screws (e.g., keyboard assembly, circuit boards)
