Research and development of Ten servo linkage assembly control systems

1. Electronic cams are adopted to replace mechanical cams in controlling the transverse seal

1) Simplify mechanical components and installation, and facilitate debugging

2) The operation curve of the equipment is gentle and the mechanical noise is low

2. The connection between the NX controller and the 1S servo motor is realized by adopting the E-CAT bus form

1) The electrical wiring is simple, saving panel assembly time and wiring costs

2) The 1S servo is of absolute value type, does not require an origin proximity switch, and has a power-off retention function

3. EtherNet network is adopted to facilitate remote data monitoring and management.

1) High-speed bus communication technology: This project will adopt the high-speed and high-bandwidth EtherCAT bus communication technology to ensure real-time, bidirectional and large-capacity data transmission between the PLC and the servo driver. This communication technology features low latency, high reliability and strong anti-interference ability, and can meet the requirements of pillow wrapping machine, high-precision and high-stability control.

2) High-precision servo drive technology: Servo drives are key components for achieving precise control. This project will select high-performance servo drivers and study their control characteristics, such as dynamic response, control accuracy, and speed regulation range. By optimizing the parameter configuration and control strategy of the servo driver, it is ensured that the pillow wrapping machine can operate with high precision and high stability.

3) Motion planning and trajectory optimization: The motion planning of pillow packaging machines directly affects the forming quality and production efficiency of drug outer packaging. This project will study advanced motion planning algorithms, such as interpolation algorithms and trajectory optimization algorithms, to achieve efficient, smooth CAM motion and precise positioning control. At the same time, considering the actual working environment of the pillow wrapping machine and the characteristics of the packaging materials, the movement trajectory is optimized to improve the production efficiency and quality of the products.

At present, pillow packaging machines are widely used in the pharmaceutical packaging industry. With the development of pharmaceutical technology, the market has put forward diverse demands for drugs, which requires packaging equipment to reach a higher and better level, mainly reflected in high-speed, stable and flexible production.
