Product Feature
Core Selling Points
1.Semi-Automatic Adaptation: After manual feeding, the twist nut machine automatically performs the nut tightening process. This not only retains the flexibility required for rapid model changes in small-batch production but also completely avoids torque errors caused by manual nut tightening, ensuring consistent quality.
2.Precision Torque Control: The torque adjustment range of the twist nut machine covers 0.5-5N・m, with a tightening precision of ±0.05N・m. This eliminates potential connection reliability hazards caused by loose or over-tightened nuts from the source, guaranteeing optimal performance.
3.Rapid Model Change: Compatible with various mainstream photovoltaic connector specifications, the twist nut machine allows fixture replacement in just 2 minutes, efficiently adapting to the production needs of multiple specifications and small batches.
4.Easy Operation: Parameters can be set with one click through the touch screen, and the twist nut machine is equipped with independent start/emergency stop buttons. New operators can master proficient operation after just 10 minutes of training, making it user-friendly and accessible.

Product Advantages
1.Efficiency Upgrade: The processing time per unit with the twist nut machine is ≤10 seconds, with a daily output exceeding 1500 pieces. This makes the production efficiency 3 times that of pure manual operation, significantly boosting productivity.
2.Controllable Quality: The tightening yield of the twist nut machine is stably maintained at ≥99.8%, effectively avoiding torque fluctuations caused by manual operation and ensuring product consistency and reliability.
3.Cost-Effective: The equipment procurement cost of the twist nut machine is only 40% of that of fully automatic models. It enables automatic upgrading without high investment, accurately adapting to the needs of small and medium-capacity production environments.

Usage Instructions
1.Pre-Production Preparation: Prepare photovoltaic connector terminals and nuts, and set the target torque through the touch screen of the twist nut machine.
2.Feeding Operation: Manually place the connector terminal into the fixture and sleeve the nut by hand, ensuring proper alignment for the twist nut machine to operate effectively.
3.Start Tightening: Press the start button on the twist nut machine, and the equipment will automatically complete nut tightening and torque detection, ensuring precise and reliable assembly.
4.Unloading and Circulation: Manually take out the finished product and repeat the feeding process to continue production with the twist nut machine.
5.Daily Maintenance: Clean up debris in the fixture daily and check the accuracy of the torque sensor monthly to maintain optimal performance and extend the service life of the twist nut machine.
