Abstract: China is a major producer of tea. Tea harvesting mainly relies on manual plucking and machine cutting. Manual plucking is time-consuming and laborious, while machine cutting lacks selectivity. To address these issues, the development of an automated tea harvesting device that is selective, efficient, and has a low damage rate has become an inevitable choice for promoting the sustainable development of the tea industry. In order to achieve automation, a tea harvesting automatic control system is implemented. This design is based on a three-axis servo control system using a PLC (Programmable Logic Controller). It explores aspects such as the selection and matching of servo motor parameters, the design of motion control flowcharts, the development and implementation of PLC programs, and the design of human-machine interaction interfaces. The Siemens S7-1200 PLC controller is used to achieve single-axis control and multi-axis control of the three-axis mechanism. Single-axis control includes job movement mode, relative movement mode, and absolute movement mode for the X-axis, Y-axis, and Z-axis respectively. The three-axis coordinated control mode includes absolute movement mode and relative movement mode. The status monitoring function is implemented through the human-machine interface (HMI). Through experimental testing of the system, it has been proven that the designed three-axis servo control system can meet the requirements of motion control.
