The invention relates to an automobile coating parallel mechanism conveyer, which comprises two functional parts: a traveling mechanism and a lifting and turning mechanism. The traveling mechanism finishes the traveling and transporting functions of the conveyer; the lifting and turning mechanism consists of one or more parallel mechanisms; the body of the automobile or other objects to be conveyed are arranged on a moving platform of the parallel mechanism; and the parallel mechanism is driven to finish the lifting and turning of the object to be conveyed. The movement of the traveling mechanism is combined with that of the parallel mechanism; the body is driven to realize advancing and retreating, lifting, tilting or composite movement thereof so as to be fully stirred in an electrophoresis tank to achieve the purpose of completely eliminating bubbles on the top of the automobile body during the electrophoresis. Because the parallel mechanism is adopted by the conveyer, the bearing capacity of the conveyer is increased so as to be suitable for conveying the bodies of different types or sizes, and the flexibility of the conveyer is also increased; and because the suspending and conveying system has a gantry structure, the conveyer successfully overcomes the defect of dropping liquid pollution and is therefore an environment-friendly conveyer on the automobile coating production line.
