[0025] The workpiece transport device for an automated coating production line disclosed in this utility model relies on the wireless communication and coordination between the control cabinet 801 and each transport control box 502. The control cabinet 801 is equipped with a main controller, a memory, a main wireless communication module, a display screen, and a keypad. The main controller is electrically connected to the memory, the main wireless communication module, the display screen, and the keypad. Each transport control box 502 is equipped with a slave controller, a voltage acquisition circuit, a slave wireless communication module, and a travel drive circuit. The slave controller is electrically connected to the card reader 524, the voltage acquisition circuit, the slave wireless communication module, and the travel drive circuit.

The main wireless communication module is wirelessly connected to each slave wireless communication module.

[0026] When the workpiece transport device for an automated coating production line disclosed in this utility model is in operation, the worker first adjusts the support angle of each workpiece support rod 535 according to the model of the workpiece 100 so that the two workpiece multi-point support units can provide stable multi-point support for the workpiece 100; then the worker places each workpiece 100 to be painted on the two workpiece multi-point support units of each workpiece transport device.

[0027] After the control cabinet 801 is started via the button panel, the main controller starts each workpiece transport device in sequence according to the set time order. The main controller sends control signals to the corresponding slave controllers through the wireless communication between the main wireless communication module and the slave wireless communication module. The slave controllers control the walking drive motor 501 to start working, so that the corresponding workpiece transport device lifts a workpiece 100 to be transported and moves it along the support track 601.

[0028] The slave controller checks whether the voltage of the battery module 504, collected by the voltage acquisition circuit, is lower than the set low-voltage threshold. If it is lower, the slave controller sends a charging request to the master controller through the wireless communication module and the master wireless communication module. At the same time, the slave controller controls the walking drive motor 501 to stop working. After seeing the corresponding request information, the worker replaces the battery module 504 on the corresponding transport control box 502, so that the workpiece transport device can continue to participate in the transport.
