Automotive assembly line

Automotive assembly lines effectively combine humans and machines and play a crucial role in automobile production. An automotive assembly line generally refers to an integrated system composed of conveying equipment (overhead and ground conveying equipment) and specialized equipment (such as lifting, turning, filling equipment, power manipulators, testing equipment, and bolt and nut tightening equipment): including final assembly interior, final assembly chassis, main assembly line, and final assembly testing line.

The S7-1500 connects to IP67 IO-LINK master modules via the Profinet bus communication protocol. The IP67 modules receive collected signals such as position and pressure, convert them into signals that the S7-1500 can recognize and process, and then output signals to control the corresponding contactors, indicator lights, and other actuators of the conveying and specialized equipment.

The IACM IP67 IO-LINK master station achieves efficient and accurate reading of RFID information through the standard IO-LINK bus, integrating into the production scheduling system for data traceability and better ensuring automobile quality.

IP67 master and slave analog modules are used in blow molding machines.

Plastic pellets are dried, melted, and then injection-molded into preforms, which are then formed into packaging containers using a blow molding machine. The empty bottles are sterilized with ultraviolet light before entering the clean filling area, where liquid is precisely injected using isobaric filling technology for cold-filling of mineral water. After filling, the bottles are sealed by a capping machine, and finally undergo labeling, coding, and online inspection (liquid level, sealing integrity, foreign objects). Qualified products are automatically boxed, palletized, and stored in the warehouse.

High-speed rotary blow molding machines require a large number of sensor signal lines and load control lines connected to I/O modules. Supei provides IP67-rated integrated modules that integrate one analog current input, eight PNP outputs, and six PNP inputs/outputs.

The analog input allows for fast and accurate acquisition of bottle wall thickness data, directly controlling high-load actions such as flow valves, ensuring the efficient and stable operation of the blow molding machine.

Robotic workstation

This solution uses an IP67-rated IO-Link PN master to connect six industrial RFID readers through IO-Link. The readers perform real-time tag read/write operations, recording traceability data throughout the product’s manufacturing process.

Sensor signals are collected via I/O points and transmitted to the controller, which then drives actuators—such as cylinders and motors—to execute robotic actions.

By integrating IO-Link with RFID, the system enhances production flexibility, simplifies equipment adjustments, and improves maintenance efficiency across the assembly line.
