[Abstract]:With the development of surface mount technology (SMT) into the mainstream technology of modern electronic manufacturing industry, placement machine as the key equipment in SMT production line has been developed rapidly. The continuous development of electronic products drives the development of assembly technology, and assembly technology puts forward new requirements for assembly process and placement machine equipment, that is, the placement machine is developing towards more intelligent, precise, high-speed and multi-function. As a result, the motion control structure is more complex. In particular, the motion structure of multi-head placement machine is more complex and the number of driving motor is large. The traditional motion control structure of parallel connection of board card is difficult to meet the requirements of motion control of placement machine. Although the rapid development of fieldbus technology and industrial Ethernet technology makes the network has become a trend in the field of motion control, but due to the number and types of servo execution equipment required by the placement machine are more, It is necessary to develop a unified network interface to realize network connection. In order to meet the above requirements, this paper studies the networked multi-axis motion control system based on EtherCAT technology. In this paper, the motion structure of four mounting machines and the requirements of motion control system are analyzed, and the structure of motion control system is planned. The motion control of 12 axes is divided into three types, each of which is realized by a network node. According to the characteristics of EtherCAT network structure, the master node and slave node unit of networked motion control are programmed and designed. According to the characteristics of different actuator of placement machine, the selection of motor is carried out, and the interface of slave node is designed according to the requirement of motor control signal. The motion control strategy of the placement machine is studied, and the requirements of the motion control trajectory of the placement machine are analyzed. According to the characteristics of high speed and high precision point position control, the motion trajectory control is carried out. The acceleration and deceleration control strategy of motor is studied. Then the related software is designed, and the network communication message planning, data structure, workflow and so on are completed. The motion control system of mounting machine based on EtherCAT is tested and verified. It is proved that the communication between master and slave stations of the motion control system is good, and the motion modules of the motion control system can run normally according to the control instructions, and meet the requirements of application.
