[0021] The working principle of the fully automatic pre-treatment system for coating workpieces provided by the present invention is as follows: Workpiece loading and initial positioning: The workpiece is placed at a preset loading position, and the slider 3 moves to drive the carrying rod 4 connected thereto to transport the workpiece to the core area of ​​the pre-processing device 1; During this process, the telescopic rod 6 mechanism automatically extends and clamps the workpiece to ensure its stability during subsequent processing; The workpiece moves to the processing position: The slide block 3 continues to move along the slide rail 2, and the carrying rod 4 and the workpiece are accurately moved to the predetermined processing position; Workpiece rotation start: When the workpiece reaches the processing position, the driving gear 92 on the carrying rod 4 begins to mesh with the rack 91 fixed inside the device; As the rack 91 moves or the driving gear 92 rotates, the bearing rod 4 is driven to rotate, thereby driving the workpiece to rotate together; Rotation and cleaning of the rotating disk 7: At the same time, the transmission rod 94 on one side of the bearing rod 4 rotates along the axis driven by the rotation of the bearing rod 4; The driving bevel gear 96 on the transmission rod 94 meshes with the driven bevel gear 97 on the rotating disk 7 to convert the rotational motion of the bearing rod 4 into the rotation of the rotating disk 7; The rotation of the rotating disk 7 is combined with the rotation of the bearing rod 4 to realize the complex motion trajectory of the workpiece in three-dimensional space, so that the cleaning liquid can fully flush the surface of the workpiece, including grooves, holes and other hard-to-reach areas; Cleaning and wastewater treatment: While the workpiece is rotating, the nozzle array sprays cleaning fluid onto the surface of the workpiece for cleaning; The waste water generated by cleaning flows into the waste water collection tank 11 through the drainage system for treatment; Automatic control and monitoring: The entire pre-treatment process is monitored and precisely controlled in real time by an advanced control system to ensure that all components operate in coordination according to the preset program; Through the viewing window 10 and internal sensors and other devices, the operator can observe the processing status of the workpiece in real time.
