[0002] As a new type of automated soldering tool, the soldering robot directly turns the robot into a direct productivity. While changing the traditional production mode, it also shows great advantages in improving productivity and adaptability to the market, and it It is of great significance to promote economic development and social progress to replace people from the harsh and dangerous working environment and carry out civilized production. However, the main control chips of the existing soldering robots mostly use 8-bit single-chip microcomputers. Insufficient computing power leads to slow operation of the welding system. In addition, the existing soldering robots use stepping motors, and their bodies are generally multi-phase structures. The control circuit needs to use multiple power tubes, making its control circuit It is relatively complicated, and increases the price of the controller, and the switching between multiple phases increases the pulsating torque of the system, which is not conducive to the improvement of the dynamic performance of the system, and the stepping motor greatly increases the mechanical noise of the system operation , is not conducive to environmental protection, and due to the frequent spot welding between the solder joints of the automatic soldering robot, frequent braking and starting, which increases the workload of the single-chip microcomputer, a single single-chip microcomputer cannot meet the requirements of the automatic soldering robot to quickly start and stop , due to the interference of unstable factors in the surrounding environment, the single-chip controller often appears abnormal, causing the soldering robot to lose control, and the anti-interference ability is poor
