Automatic Screwdriving Systems refer to automated equipment that can automatically complete the entire process of screw sorting, arrangement, transportation, and fastening according to a certain program. They are widely used in mechanical manufacturing, automotive industry, electronics, electrical appliance manufacturing and other fields, playing a vital role in improving production efficiency. This article focuses on introducing fully automatic screw machines from the aspects of working principles, classification and advantages, and applications.
Working Principles
Automatic Screwdriving Systems achieve automatic screw assembly through electric drive devices and automatic control systems. The working principles are as follows:
1. Automatic Feeding
Screws are automatically discharged from the feeder through the automatic feeding device and transported to the assembly position.
2. Screw Identification
Fully automatic screw machines can automatically identify the model and size of screws to ensure accurate assembly.
3. Screw Tightening
According to pre-set torque and angle requirements, the screw machine uses an electric drive device to quickly and accurately tighten the screws.
4. Electric Drive Device
Screw machines typically use high-speed electric screwdriver as drive devices, which are characterized by high speed and high torque to quickly complete screw tightening.
5. Automatic Control System
The screw machine controls the tightening process through an automatic control system, including functions such as torque and angle control, screw identification, and data recording.
Classification and Advantages
Common automatic screw machines can be classified by transmission method into handheld screw machines, single-axis screw machines, multi-axis screw machines, and turntable screw machines.
Feature: Eliminates manual screw picking; screws are automatically and quickly fed into the screw nozzle for the next fastening cycle.
Advantage: Frees the operator's hand to handle products, enabling efficient work and time savings.
2. Single-Axis Screwdriver Machine
Feature: No manual alignment or fastening is required. After fixing the product in the fixture and pressing the start button, the equipment automatically completes the fastening operation.
Advantage: Reduces labor costs by 1–2 personnel, improving efficiency through fully automated single-screw fastening.
3. Multi-Axis Screwdriving Machine
Feature: Designed with adjustable axis positions and quantities based on the product's processing requirements, enabling simultaneous fastening of multiple screws without operator intervention.
Advantage: Reduces labor costs by 1–3 personnel. The fully automated multi-screw fastening process is effortless and highly efficient.
4. Turntable Screw Fastening Machine
Feature: Uses a workstation turntable to achieve automatic screw driving for products requiring multi-point, multi-position, and high-speed fastening. Equipped with an external LCD touchscreen for real-time progress monitoring.
Advantage: Faster than single-axis and multi-axis models, with higher precision. Reduces labor costs by 2–4 personnel while significantly enhancing production efficiency and profitability.
Application
Automatic screw machines achieve automatic screw assembly through electric drive devices and automatic control systems, and can be applied in industries such as the telecommunications industry, home appliance industry, automotive industry, equipment processing, and toy manufacturing industry.
Telecommunications Industry: Products and equipment such as mobile phones, laptops, game consoles, telephones, watches, and keyboard lights are all applicable to fully automatic screw machines.
Home Appliance Industry: Power strips, computer monitors, remote controls, TV cabinets, refrigerators, fan remote controls, LED lighting fixtures, pendant lights, etc.
Automotive Industry: Vehicle remote controls, car gearshifts, car DVFs, car navigation devices, car parts, car keys, etc.
Equipment Category: Equipment, accessories, clinical testing equipment, computer accessories, etc.
Toy Manufacturing Industry: Assembly of toy wheels, toy parts, etc.
