【 摘 要 】

In large-scale automated production, the production process often requires the use of conveyor belts to smoothly transport the product to the appropriate location. However, during the entire transmission process, due to the long-term operation and wear of the machine, the condition of the conveyor belt is easily degraded, so that the required product cannot be accurately transported to the corresponding fixed position. In order to solve this problem, this paper uses the PLC which is often used in mechanical control to study the precise positioning of mechanical devices. Through the use of high-precision couplings, with the PLC electronic control part, optimize the structure of the precise positioning device. Practice has shown that the PLC-based mechanical precise positioning control device greatly improves positioning control accuracy and control stability than conventional devices.
