  • Aiming at the problems of low efficiency, accuracy and poor reproducibility in manual measurement of weight quality, the work flow of weight measurement, the stability of mass comparator, the motion control of three-dimensional manipulator and the positioning accuracy of loading and unloading are studied. The basic principle of PLC servo control system is analyzed, and a set of control system of weight automatic verification device based on PLC is designed and developed. Taking CX programmer as the development platform, the control system is established by using PLC and ladder diagram programming language. The automatic control of the whole process of weight loading and unloading and the automatic detection of weight quality are realized. The overall debugging and experimental verification of the system are carried out. The results show that the control system has the advantages of simple structure, high efficiency and avoiding human error, and improves the automation level and reliability of weight verification.
