The operating principles of screw and nut assembly machines primarily involve core processes such as automatic feeding, precise positioning, and mechanical locking. Specific implementation methods vary between models:
Typical Operating Principle
Automatic Feeding System
Screws, nuts, and other components are arranged and transported to the locking station via a vibrating plate, conveyor belt, or other devices. Some models, such as the PC dual-station screw locking machine, utilize a dual-station design to enable simultaneous loading, locking, and inspection.
Precise Positioning and Clamping
A robotic arm or vacuum suction platform, combined with a vision recognition system, precisely positions and clamps the workpiece, ensuring accurate alignment of the screw and nut.
Mechanical Locking Mechanism
Rotary Automatic Screw Machine: A high-speed rotating bit grasps the screw and precisely inserts it into the workpiece hole, achieving torque control accuracy of ±2%.
Expansion Screw Assembly Machine: A robotic arm grasps the screw at preset intervals, and an electric push rod pushes the nut to engage the thread.
Key Technical Features
Intelligent Control: An integrated AI defect detection system analyzes thread forming quality in real time and provides feedback on adjustment parameters.
High Compatibility: Supports various screw sizes from M1.4 to M4.0 and is compatible with plastic parts with a thickness of 1.5-5mm.
Energy-Saving Design: Utilizes a low-power servo motor and a gas-electric hybrid drive for reduced energy consumption.
Application Scenarios
Home Appliance Industry: Assembly of PC components for air ducts on air conditioners, with two-station alternating screwing of 8 M3 self-tapping screws in a cycle time of ≤3 seconds per screw.
Automotive Electronics: Attaching ABS panels to dashboards, solving the visual recognition challenge of screw holes on curved workpieces.
3C Products: Attaching router housings, using an anti-static nozzle and vacuum suction platform to prevent scratches on plastic surfaces.
