With the rapid development of the stationery industry and increasing consumer demand for product refinement, correction tape as an essential tool for daily office and study continues to see growing market demand. Traditional correction tape production relies on manual or semi-automatic assembly, characterized by low efficiency and poor precision, making it difficult to meet mass production requirements with high consistency. Particularly in the assembly of key components - the main gear (drive gear) - manual operations frequently encounter issues like misalignment and gear jamming, directly affecting product smoothness and lifespan.

In this context, the fully automatic main gear assembly machine for correction tape has emerged. Specifically designed for the core transmission structure of correction tape, this equipment integrates high-precision positioning, automatic feeding, and press-fit detection functions to efficiently complete precise assembly between the main gear and tape core. Compared to traditional manual assembly, this machine not only increases production efficiency by 3-5 times but also ensures assembly accuracy within ±0.02mm, significantly reducing defect rates. Moreover, its modular design supports quick changeovers to accommodate different specifications of correction tape products, meeting diversified production needs.

Currently, the stationery manufacturing industry is accelerating its transition towards automation and intelligence. The adoption of main gear assembly machines not only addresses industry pain points but also provides crucial technological support for enterprises to reduce costs, improve efficiency, and enhance product competitiveness. Looking ahead, with deeper integration of intelligent manufacturing, this equipment is expected to become an indispensable core component in correction tape production lines.

The system adopts the FATEK MS2C4-1616T PLC as the core control unit, utilizing EtherCAT bus technology to achieve multi-station collaborative control. It is equipped with high-precision PPU motor-driven large gear stations and inner disk stations, paired with an industrial-grade vision guidance system.

The vision system captures spring position coordinates in real time, guiding robotic arms to perform precise material picking and loading, and features automatic compensation to effectively handle material size deviations. The rotary table control system employs servo drive technology—after each station completes its operation, the system automatically triggers the table's rotation, while the unloading station simultaneously removes finished products, forming an efficient closed-loop production process.

A touchscreen provides an intuitive human-machine interface, supporting recipe management, parameter setting, and real-time monitoring, enabling operators to quickly switch between different product models. The system integrates comprehensive quality inspection functions to monitor key parameters during assembly in real time. In case of abnormalities, it triggers automatic alarms and stops to prevent defective products.

Production data is automatically recorded and stored, providing enterprises with key performance indicators such as production efficiency and yield rates, ensuring long-term operational stability.

By combining precision machinery, intelligent vision, and advanced motion control, this system achieves fully automated production of correction tape large gear assembly. Compared to traditional manual assembly, production efficiency is increased by over four times, while the defect rate is reduced to below 0.1%, offering stationery manufacturers an efficient and reliable intelligent solution.
