Automatic spraying electric control system and method for roller tractor chassis

The invention discloses an automatic spraying electric control system and method for roller tractor chassis. The method comprises the steps of recording the complete machine number of each tractor chassis by using RFID (radio frequency identification devices) equipment, screening spraying track numbers of four major parts of the chassis by a database, combining respective spraying tracks into an automatic spraying track of the chassis according to the spraying track numbers, and controlling a robot to automatically spray in a partition manner, wherein the spraying track combined spraying manner is high in adaptivity, and meets the timeliness of producing thousands of machine models with the same line. In addition, interlock, monitoring and error-proof measures are arranged between the chassis spraying track automatic combined data and automatic partition spraying electric control of the robot, the problem of equipment damage caused by collision of a sprayer and a chassis workpiece due to wrong chassis spraying track automatic combined data is effectively solved, the work method is simple and feasible, the performance is safe and reliable, and a good use value is realized.
