Detailed Guide to Using a Cordless Screwdriver

  Intelligent electric screwdrivers, also known as smart electric screwdrivers, are highly efficient tools in the industrial assembly field. They integrate high-precision sensors, servo motors, and intelligent algorithms to precisely control parameters such as torque and angle, ensuring the quality of screw fastening. This article will detail the usage of intelligent electric screwdrivers to help users quickly get started and operate them correctly.

I. Preparations before use

1. Tool connection
   • Connect the smart electric screwdriver to the transformer power supply, ensuring good contact.
   • Connect the transformer power supply to an AC220V power source, turn on the power switch, and confirm that the electric screwdriver indicator light is on to enter standby mode.
2. Bit installation
   • Choose the appropriate screwdriver bit (such as Phillips, slotted, or hexagonal) according to the screw size.
   • Turn off the power, insert the bit into the electric screwdriver chuck, and use a wrench to adjust the tightness to ensure there is no wobbling.
3. Parameter settings
   • Torque upper and lower limits: Set the torque range; the electric screwdriver will alarm if the torque is exceeded.
   • Seat detection (SSL): Prevents torque impact when screws are not screwed in, and is usually set to 35%-55% of the set torque.
   • Soft start function: For small screws (<5mm) or plastic parts, it slowly accelerates to the set speed to avoid damage.
   • You can set parameters such as torque, speed, and angle through the software interface or control panel of the electric screwdriver. 

II. Operating Procedures

1. Tighten the screws

• Forward rotation mode: Set the rotary switch to the “forward rotation” position.
• Small screws (<5mm):
  • Insert the screw vertically into the screwdriver bit, aligning it with the screw hole.
  • Press down the switch lever, and the electric screwdriver will automatically tighten the screw to the set torque and then stop.
• Large screws (≥5mm):
  • Manually insert the screw into the nut hole, keeping the electric screwdriver in a straight line with the screw.
  • Press down the switch lever to lock the electric screwdriver to the set parameters.

2. Screw removal

• Reverse mode: Turn the rotary switch to the “Reverse” position.
• Align the screwdriver with the screw hole to be removed and keep the screwdriver vertical.
• Press down the switch lever, loosen the screws, and then release the lever to complete the disassembly.

III. Real-time monitoring and data recording

• Display monitoring: During operation, you can view data such as torque value, speed, and angle in real time.
• Data recording: The tightening results (time, torque, angle) of each screw are automatically saved and can be exported to the MES system for easy traceability and analysis.

IV. Safety Regulations and Precautions

1. Operational safety
   • Do not plug or unplug the handle or controller interface while it is powered on to prevent damage to the circuit.
   • Wear protective goggles when using to avoid eye injury from flying debris.
2. Environmental requirements
   • Avoid using in environments with high humidity, oil, or corrosive gases.
   • Storage temperature range: -20℃~65℃, relative humidity: 0%~90% (non-condensing).
3. Maintenance
   • Regular cleaning: Keep the surface of the electric screwdriver clean to prevent oxidation.
   • Lubrication check: After every 1 million tightening cycles, lubricate the mechanical parts and calibrate the torque.
   • Troubleshooting: If any abnormality occurs, stop the machine immediately and contact a professional for repair.

V. Advanced Function Applications

• Multi-task switching: Supports 16 tightening tasks, suitable for different product assembly needs.
• Communication protocol: It can be linked with PLC and other equipment through Modbus-RTU/TCP protocol to realize automated production.
• Alarm protection: Automatic alarms are triggered for abnormal conditions such as excessive torque, stripping, and floating, ensuring assembly reliability. 

Conclusion

Intelligent electric screwdrivers, with their high precision and efficiency, have become a powerful tool in modern industrial assembly. Mastering their correct usage not only improves production efficiency but also ensures product quality. Following safety regulations and performing regular maintenance will maximize the lifespan of the equipment. With the advancement of Industry 4.0, the application scenarios for intelligent electric screwdrivers will become even more extensive, helping the manufacturing industry transform towards intelligent manufacturing.
