An automotive painting production line, comprising a part feeding and discharging workbench (1), a pretreatment room (2), a painting room (3), a drying room (4), an electric controller (5), and a conveying mechanism (6). A stopping module, a walking module, and a speed reducing module are used for controlling starting, stopping, and speed reducing of a drive motor correspondingly, so that the durations during which an automotive part stays on the part feeding and discharging workbench, in the pretreatment room, in the painting room, and in the drying room can be controlled. By means of the coordinative provision of an RFID information recognition module and an RFID electronic tag, the position to which a conveying device conveys the automotive part can be detected in advance, so that the conveying mechanism can be stopped on the part feeding and discharging workbench, or in the pretreatment room, or in the painting room, or in the drying room by means of the speed reducing module and the stopping module. By means of the coordinative provision of a wireless information receiving module and a wireless information transmitting device, running and stopping of a moving mechanism can be remotely controlled, and running and stopping of the conveying mechanism can be remotely controlled. Thus, the automotive painting production line can be suitable for painting operations of different automotive parts, and the applicability of the production line is improved.
